The invention relates to a conveying vehicle, namely to heat-resistant conveyor belts for transporting hot material.
The aim of the invention is to increase the life of the tape,
FIG. 1 shows a diagram of the conveyor with the location of the tape on it; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - the location of the tape on the drive drum; in fig. 4 the same on the guide drum; in fig. 5-17 tapes; FIG. 18, conveyor belt; longitudinal section HS of FIG. 19 - a tape in the place of its loading, cross section.
The conveyor belt 1 passes around the leading drum 2 and the driven drum 3 and is provided with a series of small guide rollers 4 for guiding the rear surface of the belt 1. A pair of opposite upper large guide drums 5 are located on the longitudinal intermediate part of the return section of the belt 1 , and below the space between the teeth, the lower big guide drum 6 is positioned by the reels 5 for guiding the back surface of the belt 1 ..
As shown in FIG. 2 rows of small guide rollers 4 are arranged in the form of a groove, thus the conveying surface of the belt has the shape of a groove and it has a pair of curved parts 7. As shown in FIG. and 4 the tape contains the main part 8, block 9 and ni50MeKyTO4Hbm element 10
The main part 8 (FIG. 5) contains an industrial belt inserted with a front rubber cover 11 removed and consists of a core 12, a pair of rubber covers 13 for opposite edges covering the opposite surfaces of the core 12 and a back rubber cover 14 covering the back surface of the core 12. Usually The core 12 is obtained by impregnating and coating a sheet of cotton fabric 15 of a certain thickness with rubber glue and rolling the sheet into pieces. For core 12, steel cord is recommended. Rubber coatings 11, 13, and 14 are made from a high-strength wear-resistant vulcan-1 shzirovannoy rubber. The front rubber cover 11 is removed by

directly cutting the belt from the transporting surface between the opposite sides of the front rubber cover 11 and the opposite edge rubber coating 13 with a knife to form notches reaching the core 12 and stripping the front cover 11 from the core 12.
The block 9 covers the surface of the core 12 with an intermediate element 10 located between them, mainly to form the conveying surface of the tape 1. One or a number of blocks 9 are positioned along the width of the tape 1. The block 9 comprises a base 16 and a series of individual small block portions 17. The base 16 is made of uncured rubber and has a thickness of from a few millimeters to over 10 mm, depending on the strength required for the tape dL. A small portion 17, the size of which varies from the size of the tape, has a square shape of about 1 cm% when viewed from above and a thickness of 2 to several millimeters. A series of small pieces 17 are regularly arranged on the base 16 in a staggered order and they are glued to the base by means of vulcanization, as a result of which the surface of the said base is covered with small pieces 17. The separate block part 17 is made of ceramic resistant to heat and abrasion.
The small portions 17 are glued to the base by vulcanization as follows. As shown in Fig. 6, glue 18 for rubber is applied to the surface of the base 16 and / or on the back surfaces of small parts 17. Then small parts 17 are placed adjacent to the surface of the base 16, which is covered with small parts 17, and all this is vulcanized using heat for bonding. Usually, glue 18 is applied only to the surface of the base 16 or to the back surfaces of small parts 17. Usually, the adhesive is not applied to the surface of the base, which is made of uncured rubber. In addition, when two elements are glued together (as will be described later), glue is usually applied to only one of the elements, and an element of unvulcated rubber does not crush:
cm. In order to achieve better d) fecke from skleiiapi, at the same time as glue 18, used in this case, it is possible to use additional glue when this is required.
The intermediate element 10 together with the base 16 forms a shock absorbing layer, which absorbs and reduces the impact when the transported material falls into small parts 17 on the belt. Intermediate element 10 is made of unvulcanized rubber and is in the form of a thin sheet with a thickness of 2 to several millimeters when required. The upper surface of the core 12 is covered with one or a number of intermediate elements 10, which glue the block 9 to the core 12 by means of vulcanization, so a number of small parts I7 form the conveying surface of the tape 1. The surfaces of the small parts 17 are flush with the surfaces of the edge rubber. coatings 13,
Blocks 9 are glued to the core 12 by vulcanization as follows. The front surface of the core 1 2 and / or the rear end and the front surfaces of the intermediate elements 10 (FIG. 7) and / or the rear surfaces of the blocks 9 are coated with glue. Blocks 9 are then placed with bases 16 down on the front surface of core 12 with intermediate elements 10 located between them, and vulcanized for bonding.
On each curved part 7 of the shown tape 1, a gap of .19 of the appropriate size is formed between the small parts 17 located adjacent along the width of the tape. On the curved part 7, the main part 8 of the tape, the intermediate element 10 and the base are elastically deformed, while the gap 19 closes to some extent on the front surface of the small parts 17, whereby the tape 1 is bent accordingly. Thus, the small portions 17 do not interfere with the formation of the tape 1 in the form of a gutter.
Even in the absence of a gap 19, the main part 8 of the tape, the intermediate element 10 and the base 16 are elastically deformed, simplifying manufacture. tapes 1 grooved. Thus, in this case, small hours124
These 7 7 do not cause work (guests in the molding of the gutter. It is advisable to bend the tape 1 to form a gap of about 0.5-2 mm between the small parts 17, which are located adjacent the width of the tape 1 and between small parts located adjacent along the length tapes in another part of tape 1, so even in the absence of such gaps, no difficulties are created. Although it is not always necessary to have a gap 19 when it is formed in this way, it can be filled with base rubber, glue 18 or the like for cementing when small pieces 17 are connected to the bases Niemi 16 by vulcanization.
Regardless of whether or not there is a gap 19 of an appropriate size between the small portions 17, which are arranged adjacently longitudinally to the tape, the main part 8 of the tape, the intermediate element 10 and the base 16 are elastically deformed to form an opening between the longitudinal adjacent small portions 17 on the surface of the tape 1 i.e. on the conveying surface on the parts of the belt around the lead 2, the follower 3 and the lower large guide drum 6 as shown in FIG. 3. In addition to the “shown in FIG. 4, the main part of the belt, the intermediate element 10 and the base 16 are likewise elastically deformed to form a hole between the longitudinally adjacent small parts on the back surface of the small parts 17, the part of the belt that passes over the upper large guide drum 5. Thus, small the parts 17 do not create difficulties in bending the belt 1 on its parts which pass around the reels 2, 3 and 5, 6 and the rollers 4. Moreover, when they form a gap between the small parts 17 which are located adjacent to the longitudinal tape, p can be filled with rubber base 16, the adhesive 18 or the like cementing material when small pieces 17 are bonded to the base by vulcanization. However, it is possible to do without cementing.
In the described construction, a number of small parts 17 of heat-resistant and wear-resistant material still lie essentially on the entire conveying surface of the belt 1, such
5.13
even when the tape 1 is used to transport hot material, such as coke, cement clinker or sintered ore, under severe conditions, the hot material has a high ZOO-ZOO C high temperature in the form of heated red-colored pieces that are unusually placed on tape 1, albeit temporarily, the intense heat from the hot material will not create shells with notches or similar defects in the tape. In addition, the contact of the rough surfaces of hot material is unlikely to cause noticeable wear. Accordingly, tape 1 has a longer service life than conventional tape. Tape 1 is designed for transporting hot materials, their temperature is 500-600 ° C.
Even if the belt conveyor is equipped with a pair of barriers to prevent material from falling out of belt 1, they will not significantly wear the side parts of the conveyor surface of the belt as a result of contact with it, thus this belt 1 will last longer than a conventional belt. In addition, when small parts 17 are made of ceramics and their surfaces have a good processing purity, the pies or particles of the material being transported will only stick to small parts. m 17, therefore it will not be necessary to equip the tape with a discharge-type cleaning device. This eliminates the possibility that the tape will be damaged by the metal element. The hardness of small parts effectively prevents tape wear.
Since the small parts 17 are joined by a shock-absorbing rubber layer with a core 12, the impact that occurs when the transported material falls onto the small parts 17 of the tape 1 can be absorbed and softened accordingly, even when the small parts 17 are made of ceramic or a durable solid material and can be effectively protected: from destruction or breakage upon impact and, consequently, the service life of the belt 1 is significantly increased.
The tape is made of an industrial belt by removing the front rubber from it.

the coating 11 and the placement of the intermediate element 10 and the block 9 in the formed cavity with the surfaces of small parts 17 are essentially flush with the surfaces of the edge rubber coatings 13, thus the tape 1 has the same thickness as the original belt, despite the placement of small parts 17.
A number of small portions 17 are glued by vulcanization to the surfaces of the bases 16 unvulcanized. rubber to form blocks 9, which are then placed along the surface of the core 12 with an intermediate element (s) 10 of unvulcanized rubber located between them and then the resulting device is vulcanized to bond, so that a number of small parts 17 are held in place over the entire surface of the conveyor surface of the belt 1. When blocks of a single type are made 9, tapes of various widths or thicknesses can be made. Consequently, tapes 1 having small portions 17 can easily be made from commercially available belts for a low cost with small parts glued to the core 12 with high bond strength.
FIG. 8 shows the tape manufacturing scheme of the second embodiment. The block 9 was prefabricated by applying glue to the front surface of the base 16 and / or the rear surfaces of the small portions 17 and simply glued the small portions 17 onto the base without vulcanization. Block 9 was connected to core 12 by applying glue 18 on the front surface of core 12 and / or on the back surface of the base, and then the device was vulcanized. In this case, not only the base 16 is glued to the core 12 by vulcanization, but also small parts 17 are glued to the base 16 by vulcanization, with the result that small parts are firmly bonded to the core 12. In this case, the base 16 serves as a shock-absorbing layer
According to this embodiment, one of the two stages of vulcanization and gluing was replaced by a gluing stage, which is easy to carry out, and it avoids an intermediate element.
This way, tape 1, according to this example, can be I31-capture easier and cheaper than in the first case.
FIG. 9 shows a third embodiment of the manufacture of a tape in which a series of small parts 17 are glued to the surface of the core 12 by means of vulcanization using an intermediate element 10 of uncured rubber. For bonding, glue I is applied by vulcanization to the front surface of core I2 and / or the back and to the front surface of the intermediate element 10 and / or to the back surfaces of small parts 17. In this construction, the intermediate element 10 serves as a shock absorbing layer.
FIG. 10 shows a fourth embodiment of belt manufacture, which is obtained from a commercially available belt by removing the transverse central portion (about 80% of the entire width) from its front rubber cover 11 and placing the small portions 17 into the cavity formed (the smaller portions 17 are prepared in the same way as in the first and third versions).
According to the fourth variant, a series of small parts 17 are fixedly placed along the transporting surface of the belt 1 onto its central part along the width where the material is placed for transportation, so that the belt 1 can be effectively protected from serrated cavities or similar damage when using a relatively small number of parts 17.
FIG. Figures 11-12 show the fifth and sixth versions of the tape production, according to which the front rubber coating 11 and the upper parts of the opposite edge rubber coatings I3 above the core 12 are removed from the industrial belt to accommodate small parts 17 in the cavity formed. The base 16 and the intermediate element 10 provide a pair of opposite edge portions 20, which are located outside the transverse, most distant from the center of the small parts.
According to the fifth and sixth variants, the main part 8 of the tape can be processed more easily than in the other structures described.
6128
According to the seventh variant (Fig. 13, the main part 8 of the tape is an industrial belt. An; in the first variant, small 5 parts 17 are distributed over the conveying surface formed by the front rubber coating I1 and the edge rubber coating 13. In this construction, the front rubber cover 11, the edge rubber covers 13, the intermediate element 10 and the base 16 serve as a shock-absorbing layer.
FIG. 14 shows the eighth production variant in which the block 9 is glued by vulcanization to the conveying surface formed by the front rubber coating 1 1 and the edge rubber coatings 13 of the main belt part 8 to form small parts 17. In this case, the front rubber coating 11 The edge rubber covers 13 and the base 16 form a shock absorbing layer. According to this construction, small parts can be formed in the following ways.
The method in which the commercially available belt is used as the main part 8 of the tape, like the seventh version, the small parts 17 form similarly to the third option on the conveying surface formed by the front rubber cover 5 and the edge rubber coatings 13 of vulcanized rubber.

the main part of the tape by coating the core 12 with rubber coatings 1 1, 13 and 14 of uncured rubber and gluing to the surfaces of the front rubber cover 11 and the edge rubber coating 13, vulcanized base 16, incorporated into block 9 by vulcanization or uncured base 16 included in
50 pre-manufactured block 9 by vulcanization. In the case of the above methods, rubber coatings 11, 13 and 14 are vulcanized when the base is glued by

According to the ninth variant (fig. 15) of the j tape preparation, a number of small parts of I7 are connected by means of 9.9.
the joint element 10 with the front rubber coating surfaces 11 and the edge rubber coatings 13 of the tape body 8. In this case, the front rubber coating 11, the edge rubber coating 13 and the intermediate element 10, are shock absorbers. According to this example, the small parts 17 are placed as follows: the belt inserted by the industry is used as the main part 8, like the eighth variant, the small parts 17 are fixed, like the second option, on the transport surface formed by a rubber coating 1 1 and edge rubber coatings 13 of vulcanized rubber.
The method of securing the small parts 17 simultaneously with the manufacture of the main part of the tape as in the eighth embodiment, by connecting the intermediate element 10 of unvulcanized rubber by vulcanizing small parts 17 with the surfaces of the front rubber cover 11 and the edge rubber of the unvulcanized rubber 13. FIG. 16 shows the tenth version, according to which small parts 17 are fixed simultaneously with the manufacture of the main part of the tape, similarly to the eighth variant, by gluing a series of small parts 17 by vulcanization directly to the surface of the front rubber covering 11 of uncured rubber. A pair of opposing edge elements 2 of uncured or vulcanized rubber is glued to the surfaces of the edge rubber coatings 13 by vulcanization and placing small parts distant from the center.17 In this case, the front rubber coating 1 is a cushioning layer.
According to the eleventh embodiment of the ribbon manufacture (Fig. 7), the edge sections 22 corresponding to the edge elements 21 in the tenth version are made in one piece with the edge rubber coatings 13 to simplify the production of the ribbon 1.
For the manufacture of ribbons, small parts 17 can be fastened more simply in accordance with the options ten and eleven. However, when it is required, for example, to place a heat 210
strong rubber between the small parts 17 and the main part 8 of the tape, the intermediate element 10 with high heat resistance can be made according to the second embodiment.
Small parts 17 are made simultaneously with the manufacture of the main part of the tape 1 having small parts 17. It is especially easy to make tapes 15 having small parts 17 in the manner in which block 9 is used.
FIG. 18 shows the ribbon manufacturing scheme according to the twelfth embodiment.
Tape 1 is applied in an inclined position, it is tilted down or. up in the direction of transport. The tape 1 has the first blocks 9, including the first small parts 17, which are arranged alternately longitudinally with a tape and are formed like the first embodiment of the production with a tape. The first small portions 17 have a rough surface formed by filing during or after the manufacture of blocks 9, while the small portions 17 have a smooth surface.
The tape 1 inclined according to the twelfth example of manufacture transports the materials satisfactorily, because the friction between the material and the first small parts 17, with a rough surface, has a large slip or rolling warning DD1I on the first small parts I 7,
Although the first and second blocks 9 are arranged alternately longitudinally with tape 1, their arrangement can be changed depending on the angle of inclination at which the tape is to be applied. For example, between the first blocks 9, which are located adjacent to each other longitudinally with tape 1, two or three or more second blocks 9 can be placed, although the first blocks can be used without the second blocks 9.
In FIG. 19, reference numeral 23 denotes a pair of oppositely arranged fences that lie in the same plane along belt 1 and which are located on the upper surface of the belt along the part of the belt with which the transported material falls into a groove (not shown), and also on opposite sides of a certain part
