Detailed description of the invention
A kind of coal mine scraper conveyor actuating device guard shield, comprise and be arranged on shroud body above slat conveyer actuating device by some supports 8, shroud body comprises two chutes be arranged in parallel along slat conveyer throughput direction, chute outward opening is arranged, described chute comprises cell wall, lower cell wall and with upper, the vertical side walls that lower cell wall is fixedly connected, front apron 1 is overlapped with in the front portion of two chutes, on the bottom surface and chute of front apron 1 cell wall top between be provided with and interspace in advance, back shield 7 is fixed with between the inner side of two chute rear portion vertical side walls, chute between back shield 7 and front apron is provided with shifting board 3 by the orienting lug I 9 of slide anteroposterior on upper cell wall, the actuating device of shifting board being pushed ahead preset clearance is provided with between shifting board 3 and chute, the limiting stopper 13 coordinated with shifting board is provided with in the front end of chute.Article two, chute is symmetrically arranged left chute 11 and right rail 2; During described installation, first front apron can be slided to the front portion of chute, then by locating piece 10, front apron and chute are fixedly connected.Described support 8 plays support shield body, and left chute and support are passed through gusset piece Bolt Connection, right rail and support is passed through gusset piece Bolt Connection, form respectively the guide rail that can shifting board be allowed on top to slide like this outside two of chute.Front apron is taken the front portion being placed on left chute and right rail, again by front apron and orienting lug II 12 in both sides Bolt Connection, groove on orienting lug II 12 is arranged on the lower cell wall upper surface of left chute and right rail respectively, play a part to support front apron and guiding, and between the upper surface and the bottom surface of front apron of left chute, right rail, form certain headspace, for shifting board forward slip reserves space.Connected by bolt with inside the vertical cell wall of left chute, right rail by back shield, the position of its upper surface is lower than the position of shifting board lower surface; Shifting board is put into after on left chute and right rail, orienting lug I 9 is connected by bolt with shifting board.Want to interlock with orienting lug II 12 in the upper cell wall bottom surface of orienting lug I 9 chute, ensure not make a difference with orienting lug II 12 in shifting board moving process.By the operation of hydraulic efficiency pressure system hydraulic valve, realize the expanding-contracting action of hydraulic ram, promote shifting board and move forward with backward along chute.
Actuating device hydraulic motor chain tightening device is used to adjust scraper conveyor scraper chain predetermincd tension at needs, or maintenance, when more sliding actuating device connects the friction limit square device in cover cylinder, the hydraulic ram of shroud body is stretched out, drive shifting board moves forward, shifting board is made to be in open configuration, so motor tension chain device with connect cover cylinder and will expose, in the space that down-hole is severe and narrow, can under the condition not dismantling power part guard shield, miner just can carry out Related Work, both improve the comfort feature of operation, greatly reduce again the intensity of work, improve the safety and efficiency of operating maintenance.
The bottom surface, both sides of shifting board is arranged with some roller I 4 respectively that coordinate with cell wall on chute; The middle top surface of shifting board is provided with roller II 5 that is some and front apron bottom surface; Described front apron is arranged on chute by the orienting lug II 12 coordinated with lower cell wall, cell wall is provided with the locating piece 10 front apron and chute are fixedly connected under chute; Described actuating device is the hydraulic ram 6 be symmetricly set on inside two chute vertical side walls, and the cylinder body of hydraulic ram and the lower cell wall of chute are fixedly connected, and the piston rod of hydraulic ram connects with the front portion of shifting board.On shifting board, left and right bilateral symmetry is equipped with roller I, roller I contacts with left and right tongue upper surface respectively, can reduce friction in the process of shifting board movement, roller II 5 on shifting board, be in order to when shifting board moves to below front apron, reduce the frictional resistance between shifting board and front apron.
