Abstract
The invention discloses a flexible guarding protection-assisting device for a hydraulic support. The flexible guarding protection-assisting device comprises a face guard hinged to an extendable beam or top beam of the hydraulic support. Lap plates made of flexible flame-retardant materials are connected to left, right and lower side edges of the face guard respectively. The lap plates connected to the left, right and lower side edges of the face guard are of an integral U-shaped structure. The flexible guarding protection-assisting device has the advantages that the problem of unsafe factors caused by the fact that gaps exist between face guards of an existing adjacent hydraulic supports is solved; at work, the adjacent lap plates are overlapped to protect gaps which cannot be protected by the face guard.
Description
Technical field
The present invention relates to a kind of hydraulic support wall supporting auxiliary protecting device, especially relate to breaking roof exploitation, hydraulic support flexible side protecting auxiliary protecting device under thick and condition of thick seam in soft.
Background technology
Coal wall caving and beam-ends roof fall are that the principal element of adopting efficiency and safety of workers is combined in impact, and under particularly breaking roof exploitation, soft medium-thickness seam and condition of thick seam, problem is even more serious.Under action of underground, coal wall caving and beam-ends roof collapse bring out mutually, form vicious circle.Face guard is to improve the adaptive a kind of usual means of hydraulic support, and its effect is to be adjacent to rib by wall supporting, to rib, applies a support force, prevents wall caving.Once wall caving, also can block wall caving coal and not enter walkway, and prevent that wall caving from continuing to expand.But, fully-mechanized mining working, between hydraulic support, all can leave wall supporting protection less than gap, and occur once wall caving, coal cinder can collapse to hurt sb.'s feelings from these gap locations.
Summary of the invention
The object of the invention is to provide a kind of hydraulic support flexible side protecting auxiliary protecting device, for protect between adjacent side protection plate of hydraulic support protection less than gap.
For achieving the above object, the present invention takes following technical proposals:
Hydraulic support flexible side protecting auxiliary protecting device of the present invention, comprises the face guard being hinged with Telescopic beam of hydraulic bracket or back timber; Left and right, lower side edge along described face guard are connected with respectively the lapping plate that flexible flame retardant material is made.
Be connected to that described face guard is left and right, the lapping plate on lower side edge is whole U-shaped structure.
The invention has the advantages that and solve between existing adjacent side protection plate of hydraulic support due to the unsafe factor that exists gap to bring.During work, the overlapping overlap joint of adjacent lapping plate by face guard protection less than gap protect.
Accompanying drawing explanation
Fig. 1 is that the present invention uses view.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Fig. 3 is used adjacent two face guards overlap joint schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, 2, 3, hydraulic support flexible side protecting auxiliary protecting device of the present invention, comprises the face guard 1 being hinged with Telescopic beam of hydraulic bracket or back timber; Left and right, lower side edge along described face guard 1 are connected with the lapping plate 2 that flexible flame retardant material is made respectively, and described lapping plate 2 is whole U-shaped structure, by bolt, is fixedly connected with face guard 1.
Claims (2)
1. a hydraulic support flexible side protecting auxiliary protecting device, comprises the face guard (1) being hinged with Telescopic beam of hydraulic bracket or back timber; It is characterized in that: left and right, lower side edge along described face guard (1) are connected with respectively the lapping plate (2) that flexible flame retardant material is made.
2. hydraulic support flexible side protecting auxiliary protecting device according to claim 1, is characterized in that: be connected to that described face guard (1) is left and right, the lapping plate on lower side edge (2) is whole U-shaped structure.
