    A scraper-chain conveyor has channel-sections or pans arranged end-to-end along which a scraper-chain assembly is circulated. Each pan is composed of rolled side walls with a floor plate welded therebetween. The side walls are reinforced by upper and lower elongate bars welded to their exteriors. These bars have shaped apertures designed to accept and locate the heads and shanks of bolts used to fix attachments to the side walls. The side walls are recessed behind the apertures and these recesses define with the apertures, pockets for receiving the heads of the bolts.

    专利说明:

    The invention relates to chain scraping downhole conveyors used in the mining industry. The known section of the groove of the chain scraper downhole conveyor contains side profiles connected to the base, which between the upper and lower shelves have V-shaped recesses with welded intermediate holders and provided with a side covering consisting of almost the entire length the gutter sections of the reinforcement bars, with side profiles boiled to the profile webs, and having holes along the length of the Cl3 bolts. Due to welding to the side profile of the reinforcing bars, the gutter sections acquire an increased width. However, in these Cases, comparatively flat plates can be made on the reinforcement bars to accommodate bolt heads into which relatively thin bolts can be inserted, which reduces the strength of the bolted joints. The closest to the invention in terms of the totality of features and the effect achieved is the rail section of the chain-driven scraper downhole coil weir, which includes a base fixed on the sidewalls with V-shaped grooves between the upper and lower shelves, in which intermediate holders are welded, and located along the entire length of the sidewalls, reinforcing strips with holes and recesses for the heads of bolts welded to the outside of the lintels of the side profiles and parts of intermediate holders protruding from the V-image of the breathing grooves 2. For Wow, in order to use fastening bolts in this section of the required strength, the reinforcing bars must be of relatively large thickness. In conformity with this, the sections of the gutter with reinforcing strips welded to the sidewalls should have a relatively large structural width. However, this is a disadvantage, in particular, when using the gutter sections in close underground workings. The width of the space should be as small as possible in order to manage the roof reliably. In addition, on the charging side of the downhole conveyor, usually, there should be installed a leg drive with hydraulic drive, often together with other additional devices. In order to ensure that there is enough space between the gutter sections and the hydraulic walking support, there is enough space for the workers to pass the lava, the walking support should be moved relatively far from the clearing hole. This leads to the fact that the tops of the walking support, supporting the roof, should be relatively far above the conveyor to the clearing slab. For these reasons, the constructive width of the conveyor should be no larger than necessary, without reducing the required cross-section of the layer of material being transported. At the same time, in practice, this is only a few centimeters. However, reducing the thickness of the reinforcing bars leads to a decrease in the strength of the fastening bolts for mounting the parts on the reinforcing bars. In addition, dredging gblovok bolts open up, which leads to clogging coal coal these holes. The aim of the invention is to ensure the durability of bolt fastening of parts on reinforcing bars of reduced thickness. This goal is achieved by the fact that in the groove section of a chain scraper downhole conveyor comprising a base fixed on the sidewalls with V-shaped grooves between and lower shelves, in which intermediate holders are welded, and located along the entire length of the sidewall reinforcing strips with holes and grooves for bolt heads, welded to the outside of the lintels of the side profiles and parts of intermediate holders protruding from V-shaped grooves, the lintels have grooves in the reinforcement points Lankah recesses for bolt heads, each of which, together with the recess for the bolt head in the reinforcing bars, form an oval socket, the longitudinal axis of which passes
    parallel to the axis of the housing section, while the thickness of the slats is less than the number 1 of jumpers.
    FIG. 1 shows a section of a groove of a chain scraper face-face conveyor 5, side view; in FIG. 2, section A-A in FIG. one.
    The section of the groove of the chain scraper downhole conveyor contains two sidewalls 1, which are interconnected by means of 10 welded base 2. The sides 1 have upper 3 and lower 4 shelves, a middle edge 5, vertical bars 6 and 7, as well as knees 8 and 9, which converge towards the base. Vertical lintels 6 and 7 connect the knees 8 and 9 to the upper and lower shelves 3 and 4. On the outside, the elongated sides of the knees 8 and 9 form a profile V-shaped recess 10, which is located midway between the upper 3 and lower 4 shelves. Above the base 2 passes the upper BetBb con- 2S weier, and below it the lower branch. Along connected from separate sections of the gutter of the entire body of the conveyor passes at least one endless chain with located. zo on her scrapers ..
    In the V-shaped recess 10 along the entire length of the gutter section, intermediate holders 11 are welded, koto ry stand out of the profile 35. recesses 10. Intermediate holders 11 have a bolt hole 12 open to the side. Two reinforcing strips 13 and 14 are welded to the sidewalls 1 from the outside, the thickness of which is less than the thickness of the jumpers 6 and 7, made in the form of rolled metal. The reinforcing bar 13 of its upper 15 is at the level of the upper side 16 of the upper shelf 3. In a corresponding manner, the lower surface 17 of the lower flange 4 is flush with the lower surface 18 of the reinforcing bar 14. Reinforcing planes Ok 13 and 14 pass through along the length of the gutter sections. Reinforcement bars 13 and 14 are welded on one side with sidewalls 1, and on the other side with protruding parts 19 of pro- s-. perish holders 11.
    Reinforcement bars 13n14 have holes and nwfMKH 20 for heads
    bolts oval contour. The longitudinal axis of the opal runs parallel to the longitudinal axis of the section. The notches 20 for the bolt heads are in each case on a vertical line with notches or holes 12 intermediate holders 11. Corresponding notches 21 for bolt heads are provided under the holes 12 of the intermediate holders 11 on the reinforcement bar 14. The holes for the bolts on the intermediate holders and reinforcing strips are arranged so that on the outer side of the sidewall there are three parallel rows of holes passing along the gutter sections, and the openings of these rows are located along one vertical so that A lead 12 is a recess 21 for the bolt head, and above this hole is a recess 20 for the bolt head.
    On the jumpers 6 and 7 in individual places there are recesses 22 in the form of grooves, which together with grooves 21 or 20 for bolt heads: form one nest, the depth of which is equal to the sum of the depths of the grooves 2C, 22 or 21, 22. in the bridge, perform in the interior of the oval by milling in the side walls obtained by rolling.
    Ka reinforced sidewalls 1 can be attached in the usual way and structural elements are known, such as loaded sheets of metal, guiding strips guiding the tires of the mining machine. Bolts are used as fasteners, which. with their heads they are screwed into the sockets, with the bolt body passing through the hole 12 of the corresponding intermediate holder. Similarly, the structural elements can also be fastened by means of bolts 23 and 24, the rods of which pass through the openings of the grooves 20 or 21 of the reinforcing bars 13 and 14, the heads 25 or 26 of which are located in account grooves reinforcing strips and profile jumpers. At the same time, the heads of the bolts are supported on the skis 27 or 28, formed by the front notch 20 or 21 for the 14) side of the bob.
    Generally, structural elements, such as side sheets of metal and the like, are fastened to only two rows of bolts to the sidewalls 1. In the event that loads from the middle of the conveyor are transmitted to the side sheets of metal or similar elements, it is recommended to use the upper row of holes for fastening them. , as well as a number of holes formed in the intermediate holders 11. With oppositely directed loads
    The attachment of structural elements is more expedient to produce by means of bolts, which on one side rest on intermediate holders 11, and on the other hand on bolt sockets in the lower part of the sidewalls.
    This embodiment of the proposed device provides the strength of bolting parts on the reinforcing bars of reduced thickness.
