    • 专利摘要:
    A mine roof support has a slidable extension at the front end of an auxiliary roof cap pivoted for swinging up and down on a main cap. To prevent the extension from being extended when the angle of inclination of the auxiliary cap is too high an insulative cylindrical block is fitted to say the auxiliary cap to partially rotate as the auxiliary cap pivots. A flattened region on the block supports a metallic plate and indexes as the auxiliary cap pivots. A resiliently-mounted proximity switch on the main cap senses the presence of the plate and produces a signal to prevent the extension from being extended.

    leaf spring 22 fixed switch, made in the form of a relay 23. The switch faces the sleeve 16 and is installed with the ability to interact with segment 18, At a certain angle of inclination segment
    18 rotates in front of the surface of the relay 23 and generates a signal. The latter arrives at the electronic control system i and prevents the extension of the scattering valve, the visceral. 3 hp f-ly, 3 ill.
    The invention relates to a control device for temporary tops located on the suspended tops of the underground supports, especially for sliding tops with a switching device connected between the tops of the suspension and to the installation of the tops.
    The purpose of the invention is to prevent the retractable console from extending at a certain angle of inclination of the visor.
    FIG. 1 shows a mechanized lining with a visor and extendable top, side view; in fig. 2 — node I in FIG. 1, side view; in fig. 3 - control device, bottom view.
    The mechanized support 1 has a base 2, an overlap 3, and also support posts 4 embedded between overlap 3 and the base 2. To the overlap 3, the fence 5 is hinged on the side of the inlay, and on the coal side is the visor 6. 7 by means of a cylinder 8. A sliding console 9 is movably mounted above or in the visor 6, which is extended by means of a hydraulic cylinder 10 in movement. The cylinder 10 through the synchronous control device is automatically connected to the cylinder 11 of the movement of the mining device 12.
    On the visor 6 in the area of the hinge axis 7 in the recess 13, the holder 14 of the switching device 15 is rigidly fixed. The holder 14 is rigidly connected to the sleeve 16, which is hinged on the axis 7 of the hinge mounting bracket 6 to the overlap 3. The switching device 15 also contains a cylindrical non-metallic sleeve 16, made of plastic, mainly of ultraviolet, and a metal contact element (segment) 18, attached to, ke f with a flap 17. Metallic type, which is an element of 18, is pe rsvin., Cri i- l

    but made of stainless steel and fastened with screws 19 g-i g-ekupsg and c, - 17, extended to the bushing (switching device 15 (its sleeve 16) through the threaded pin 20 with a force and geometric closure rigidly united with the holder 14. The overlap 3 is made with an edge 21 on which; by means of the leaf spring 22 is fixed a switch made in the form of a proximity relay 23. The switch 24 is turned to the sleeve and is installed with the possibility of interaction with the segment.
    The proximity relay 23 adjoins with its sensitive surface to the outer perimeter of the cylindrical switching slide 15 so that the prc; -.- divided angle of inclination the metal contact element 18 rotates; in front of the sensitive surface of the proximity relay 23 and generates an electrical signal. This electrical field is recycled to the electronic system: the control of the support and prevents the extension of the sliding arm 9.
