    The invention relates to equipment for mechanizing the extraction of coal by an underground method, in particular, to coal mine control devices.
    plow
    A device for controlling a plow, including a linear section of the conveyor, a guide plow, connected to it by an articulated conveyor plate, a power jack and a horizontal slider (1].
    The disadvantage of this device is its insufficient adjustment efficiency during the operation of plow complexes.
    The closest in technical essence to the proposed one is the plow control device, including cantilever beams pivotally connected to the conveyor 20 with the possibility of regulation in vertical and horizontal planes through an intermediate element, the ends of which are located in the rails on the movable roof support 25, and a control jack [2 ].
    However, this device does not accurately control the position of the plow in the soil of the formation. thirty
    The purpose of the invention is to increase the efficiency of plow control in a vertical plane with uneven soil.
    This goal is achieved by the fact that the intermediate element is made with a jack for hydraulic jack control, and the hinge connecting the intermediate element with. beams made cylindrical, while the axis of the hinge coincides with the longitudinal axis of the intermediate element, and the intermediate element is made of two identical parts connected along the longitudinal axis and forming a jack for control jacks.
    11a of FIG. 1 shows the proposed control device, side view; figure 2 - connection of the cantilever beams with the guide plow, side view; in Fig.Z - an intermediate element, a horizontal section; figure 4 - one of the embodiments of the invention, in which the guide beams are located above the bases of the mobile lining; in FIG. 5 is the same side view ;, FIG. 6 is the same top view; 7 is an embodiment of the invention.
    A scraper conveyor 1 is located before the face. On the conveyor 1, a guide for the plow is mounted on the side of the bottom (the plow and the guide are not shown for the plow).
    The plow has a portal 2 protruding beyond the conveyor 1, resting on a guide 3, which is mounted on the sides 4. The vortices 4 are attached to the conveyor 1 from the side of the worked out space. On the same side. conveyor 1 sets of 'support, predominantly enclosing' types are installed. The lining kits have an integral or composite base 5, a shield 6 hinged to it and hydraulic struts 7, hingedly supported by their lower parts on the base 5, and bear the upper part of the shield (not shown), pivotally connected in the upper part to the shield 6. Tops .ικ supported the uprights 7. between the guide plow and the plow taken bolting control device including control hydraulic cylinders 8 which shtokami.9 its piston pivotally connected through the bolts 10 with connecting arm 11, pri- 1 fastening at the top of on the sides 4. The control hydraulic jacks 8 have ball heads 12, with the help of which they are located with the possibility of comprehensive rotation in the sockets 13 of the intermediate element 14, By the intermediate element 14, the cantilever beams 15 are connected to the guide of the plow., and therefore the conveyor 1. The ends of the cantilever beams 15 are placed in guides 16 located at the bases of 5 sets of supports. The beams 15 have pins 17, which are installed, for example, in U-shaped guide bases in the forward direction. At the same time, a location is chosen in which the beams 15 can be rotated around the pins 17 in a vertical plane, while the rear ends of the beams are fixed from being lifted by the pins 17.
    The intermediate elements 14 are connected through a hinge 18 with the conveyor 1, and therefore, with the hinged part of the conveyor located on the side of the mined space. The axes ..- of the hinges 18 are placed along the longitudinal axis of the conveyor 1, due to which the conveyor 1 and the plow guide, On the one hand, and the cantilever beams 24, on the other hand, can perform rotational movements around the axes of the hinges 18. Since the cantilever beams'15 are held from lifting at their rear ends with pins 17, when the hydraulic jacks 8 are extended or retracted, the conveyor 1 together with the plow guide rotates in a vertical plane either up (when retracting) or down (when extending). In this way; You can precisely adjust the cutting horizon of the plow.
    The intermediate elements 14 are made of two parts (2 and 3), which are connected along the longitudinal axis X. Both parts 19 and 20 are of the same design (they are mainly made of stamped forgings or castings). The detachable connection of the parts 19 and 20 is horizontal bolts passing through the coaxial holes of both parts. Bolts 21 are located on both sides of the socket 13, in which the ball head 12 of the hydraulic jack 8 of the control is located with the possibility of rotation of L in all directions. The socket 13 formed by both parts 19 and 20 (FIG. 2) is designed so that it covers the ball head 12 by more than half. Therefore, the ball-head works in tension in the socket, so that when the hydraulic jack 8 is pushed in, it remains in the socket. In addition, both parts 19 and 20 (FIG. 2) of the intermediate element 14 have a recess 22 for rotating the hydraulic jack 8 and together form a hole 23 for the bolt 24, with which the intermediate element 14 is pivotally connected to the bracket 25. The hole 23 and the bolt 24 form hinge 18 (figure 1).
    The bracket 25 (FIG. 3) has cylindrical recesses 26 in the rear part, into which the bolts 24 enter at its ends. In addition, the bracket 25 has holes 27 for the bolts 28, by means of which it is attached to the conveyor 1 from the side of the worked-out space. The bracket can be attached to the holders (not shown) of the linear sections of the conveyor, which are welded into the V-grooves 2 of the 9 sidewalls and on which the bolts 28 are supported by their heads 30. To fasten the brackets 25 to the conveyor, another bolt 31 can be used that passes through it rests on the strap 32 of the conveyor side, using bolts simultaneously attached to the conveyor from the space mined side 4. These sides protect the bolts 24 from falling out of the recess 26 of the bracket 25. Both parts 19 and 20 of the intermediate element 14 issue are mounted on the opposite side so that they form a hinge 33. In this cylindrical, rotating hinge 33, a rotary element 34 is arranged to rotate about an axis. The hinge 33 and the pin portion of the rotary element included in it are made stepwise (FIG. 3)., So that a tensile connection is created between the Rotational, element 3 4 and the intermediate element 14. Two beams 36 and 37 are attached to the element 35 with their front ends which, as can be seen from FIG. 3, in the direction of the X axis, converge at their ends to each other.
    the beams 36 and 37 at the rear ends have trunnions 17 (Fig. 1) or other guiding bodies with which they move in the guiding bases 16 of the corresponding support set. It is recommended that the beams 36 and 37 be connected at the rear ends through a transverse clamp, on which the hydraulic jack rests with the possibility of rotation, the piston rod of which is pivotally connected to the console 35 of the lining base. A hydraulic jack 38 is located between the beams 36 and 37 at the rear of the lining kit under the shield 6. This hydraulic jack does not block the road between the conveyor 1 and the struts 7 of the lining kit. In addition, the inclined position of the beams 36 and 37, in which their front ends are pressed close to each other, and are also connected through the element 34 to the intermediate element 14, leads to space saving and simplification of the design of the connecting parts, the beam with the conveyor 1. At the same time spherical, swivel connection between the hydraulic jack and the intermediate element, as well as the presence of a cylinder. The hinge between the beams and the intermediate element provides relative movement between the plow guide, and therefore with the cone, and the support, and the beams, which is suitable, for example, for the extraction of coal in accordance with uneven soil, etc.

    Figure 4 schematically depicts an example embodiment according to which rod-shaped beams 15 which are placed above the bases 5 of the corresponding support set. The connection of both beams 15 with the intermediate element 14 is carried out in this case through a special rod head 39, which has connections 40 and 41 ( 5 and 6) for beams 24 located in the horizontal plane, as well as a connecting body 42 for connecting to the intermediate element 14. Connections 40 and 41 are located above the connecting body - 42. They consist of fork-shaped astey (4 and 5) provided with connection holes 43, in which their front ends are round bars 15 (Figure 4). The connection of the beams with joints 40 and 41 can be carried out by clamps, tubular split pins or other mechanical connecting bodies. Located coaxially below both connections 4Q and 41 at the rod head, the connecting member 42 has a cylindrical hole 44 into which the end 45 of the spigot of the intermediate element 14 enters. The connection of the rod head 39 with the intermediate element 14 is preferably carried out so that these two parts are rotatable around axle axis 45.
    Together with the axis of the hinge 18 (Fig. 13), a cardan joint is obtained between the beams and the guide of the plow, I and therefore the conveyor.
    The rod head 46 (Fig. 7) basically corresponds to the head 39. However, it is higher than the connecting member 47 * having a cylindrical bore.
    I hole has a head part 48, which is equipped with connections 49 for four rod beams 15. Thus, beams are arranged in pairs, one above the other and adjacent to each other, Beams 15, which are connected by their 1 front ends to joint head 46. Connections 49 also consist of fork-shaped bodies equipped with holes or holes for inserting guide rails 15. Tensile connection of beams to the rod head is achieved due to the fact that the beams in their longitudinal direction can be connected This can be easily achieved by interchangeable bolt connections. The head part “48 of head 46 has in this case a group of holes 50 for bolts that pass through the front end of the beam. This connection of the head allows you to adjust the distance between the support sets and the conveyor and the plow guide .
    The intermediate element 14 (Fig.7) has a trunnion end 51 included in the hole of the connecting body 47 of the head 46 ,. A groove 52, semicircular in cross section, extending about 180 ° around the trunnion end and ending at point 53, is located at the trunnion end. Connector 47 has a communicating transverse groove 54, which also has an approximately semicircular cross section and together with the groove forms a corresponding circular cross section of bolt 55 groove. Using bolt 55, parts 14 and 46 are tightly bound. Groove 51 allows for relative displacement between parts 14 and 4 of 6- around the axis of the pin, i.e. vertically to the axis of the bolt 18. This rotational movement between the connecting link and the head can also be provided in the exemplary embodiment. According to FIG. 4 - 6. The same applies to the rearranged - reinforcement of the beams 15 to the reaping head.
