Abstract
The utility model provides a protective device. The protective device comprises a protective plate and a hydraulic cylinder, wherein the protective plate is vertically arrange on a piston bar of the hydraulic cylinder, and the tail end of a cylinder body of the hydraulic cylinder is used for connecting with a top beam of a hydraulic support. Due to the fact that the piston of the hydraulic cylinder pushes out and takes back the protective plate, the protective device is enabled to stretch out when needing using and be taken back when the protective device is not needed using. The protective device can protect a full-face distance from a front pillar of the hydraulic support to a coal wall section, prevent flying coal produced in working from damaging to workers on a working surface, and achieve safe production of a coal mine.
Description
Technical field
The utility model relates to a kind of mechanical device, relates in particular to a kind of protector.
Background technology
When Inclined Full-mechanized Mining Face carried out operation under coal mine, broken coarse coal can cause following security threat to the work plane constructor: 1, directly scurry in hydraulic support, the staff is damaged; 2, damage to the personnel in the rib scope entering the hydraulic support front column.
Existing solution is exactly the situation that the personnel of arranging work check top board and coarse coal, and arranges the staff who dresses safeguard procedures to set up protective equipment.Yet, do like this and still have potential safety hazard.Therefore, need badly and propose a kind of protector, to eliminate the potential safety hazard of fully-mechanized mining working, realize the safety in production in colliery.
The utility model content
The utility model provides a kind of protector, is used for when the fully-mechanized mining working operation, and the coal that flies that produces when preventing operation damages the staff in work plane, to realize the safety in production in colliery.
The utility model provides a kind of protector, comprises protected apron and hydraulic cylinder, and described protected apron vertically is arranged on the piston boit of described hydraulic cylinder, and the cylinder body end of described hydraulic cylinder is used for being connected with the back timber of hydraulic support.
Protector as above, wherein, described protected apron comprises crossbeam and riser, described riser top is connected with described crossbeam.
Protector as above, wherein, described crossbeam is the transverse beam body of i iron material.
Protector as above, wherein, described riser comprises steel plate and two rubber strips, described two rubber strips vertically are disposed on described steel plate.
As shown from the above technical solution, the protector that the utility model provides, release and regain protected apron by the piston boit of hydraulic cylinder, protector when using, is stretched out by needs, regain when not needing to use, can carry out full face protection to the distance of rib section to the hydraulic support front column, the coal that flies that produces when preventing operation damages the staff in work plane, has realized the safety in production in colliery.

The specific embodiment
Fig. 1 is the top view of the protector of the utility model embodiment.As shown in Figure 1, the protector that the present embodiment provides specifically comprises protected apron 101 and hydraulic cylinder 102, and protected apron 101 vertically is arranged on the piston boit 103 of hydraulic cylinder 102, and the cylinder body end 104 of hydraulic cylinder 102 is used for being connected with the back timber of hydraulic support.
Particularly, protected apron 101 can be used for when the fully-mechanized mining working operation for being used for stopping the platy structure that flies coal, stops that broken coarse coal enters to injure the staff in hydraulic support by a crashing object.
The protector that the present embodiment provides, protected apron 101 is released and regained to piston boit 103 by hydraulic cylinder 102, protector when using, is stretched out by needs, regain when not needing to use, can carry out full face protection to the distance of rib section to the hydraulic support front column, the coal that flies that produces when preventing operation damages the staff in work plane, has realized the safety in production in colliery.
Fig. 2 is the elevation of the protector of the utility model embodiment.
In the present embodiment, the protected apron 101 of this protector further can also comprise crossbeam 105 and riser 106, and crossbeam 105 can be the transverse beam body of i iron material.Particularly, the crossbeam 105 of this protected apron 101 is connected with riser 106 tops, and an end on crossbeam 105 tops is connected with the piston boit 103 of hydraulic cylinder 102, stretches to control stretching out and withdrawal of protected apron 101 by piston boit 103 in use.
In the present embodiment, the riser 106 of this protector further can also comprise steel plate and two rubber strips 107.Particularly, two rubber strips 107 vertically are disposed on steel plate, use bolt 108 to be connected with steel plate by punching.Yet the utility model is not as limit.
The protector that the present embodiment provides, its course of work can with reference to the associated description of the described protector of Fig. 1, not repeat them here.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
