    It is an object of the invention to provide an improved shield-carrying roof support unit which has a linkage for adjusting the elevation of the cap while the pivotal connection between the cap and the shield is constrained to move substantially at right angles to the base frame. The provision of auxiliary links having pivotal connections at properly selected points results in a linkage which has a precisely defined configuration and avoids an overloading of the pivotal connections such as could occur in known shield-carrying roof support units of the same kind.

    (54) SECTION OF MECHANIZED SHIELD STRAP
    The invention relates to mining, specifically to mechanized fortifications for cleansing faces. The known mechanized shaft support section, which includes a base with a support, an overlap fence made in the form of a lever pivotally mounted on a support, and a power hydraulic jack installed between the base and the overlap 1. removable reservoir capacity. The closest to the technical essence of the present invention is a mechanized shield panel section comprising a stand connected to the base and the top hinged on the panel fence which is hinged to the base by means of inclined mounted driving arms, the hinges of the connections with the panel fence are placed at a distance shorter than the hinges located at the same height of their connection with the base, with the drive lever located on the side of the tab, shorter than the lever located with On the side of the bottom, and on the top of the hinge is fixed at one end, auxiliary i drive lever, the second end of which is hinged on drive lever 2. The disadvantage of the mechanized shield support section is the unfavorable interaction with the roof rocks of the rear honsoli top when it is required length, which leads to breakage lining and rock falls. The purpose of the invention is to increase the reliability of work by unloading the roof from the nipples arising near the chest in the upper forces. The goal is to reach the fact that the upper to the place of the hinge attachment to the Shield fence is complete with the console directed downwards, the attachment of the end is auxiliary; the drive lever to the top is made on this console, and the stand is connected to the top in the place of the hinged joint of the top with the shield enclosure. FIG. 1 shows a section of mechanized shield support in the extended position, side view; 2, the same plan view; FIG. 3 is a view A of FIG. one; in fig. 4 - section
    lining in the folded position, side view.
    The lining section includes a base 1, on which the shield fencing 2 is hinged by means of downhole drive 3 and 4 downhole levers. The length of the lever 3 is greater than the length of the lever 4. The distance between the hinges 5 and 6, connecting these levers with the base 1 and being at the same height, is greater than the distance between the hinges 7 and 8, connecting the levers with the panel shield. A hinge 9 is attached to the shield shield by the top to 10, made with the console 11 pointing downwards. The console 11 is hinged to the drive downhole lever 3 by means of an auxiliary drive lever 12 and axes 13 and 14. A swivel pressure element is hinged on the top of the bottom side. 15 connected to the top by means of an axis 16 and a hydraulic jack 17 of the control. A hydraulic post 18 is installed between the base and the top one, and the axis of its hinge attachment with the top one is flush with the joint 9 relative to the coal face and the working soil.
    In the section can be installed not one, but several gidroek. Auxiliary drive lever 12 is made in the form of a power cylinder. On base 1, a hydraulic cam 19 is secured, associated with a downhole conveyor belt.
    The shield fencing 2, the bottomhole console 11 3, and the auxiliary 12 drive arms form a parallelogram that allows the hinge 9 to move vertically when the section height changes in accordance with the varying thickness of the formation.
    Making the lever 12 in the form of a power cylinder allows the upper to be pressed against the roof in all cases where it is non-parallel to the soil. After the passage of the excavation machine and the movement of the conveyor, it is unloaded and, by means of a hydraulic cylinder 19, is moved to the bottom. Then, the hydraulic post 18 is moved apart up to the stop of the top 10 into the roof and spread, and the rotary element 15 is pressed against the roof by means of a hydrojack 17.
    The implementation of the lining section with the auxiliary lever connecting the Kori salt top with the bottom-hole actuating lever provides for an increase in the stability of the section, unloading the hinge connecting the top to the shield, as well as better interaction of the top with the roof.
