It is, of course, also possible to be other materials, particular determination is not done herein.The quantity for grabbing ring 5 can be one, be also possible to multiple, act
For example, it can be 2,3,4 or 5, it is, of course, also possible to be other quantity, do not do particular determination herein.
Embodiment further provides a kind of gear cash systems for the disclosure, which may include any of the above-described embodiment party
The gangue stopping device and protective plate of formula, protective plate can be set to side of the top plate 2 far from substrate 6, and when in use, top plate 2 can contact
In protective plate.The specific structure and beneficial effect for keeping off cash system can refer to above-mentioned gear cash system, not repeat herein.
Protective plate can be matched with plate-like structure, shape with the shape at the top of tunnel.It for example, can be with
Be rectangle, be also possible to circle, can also be other shapes, will not enumerate herein, material can be metal, alloy or
Stainless steel etc., does not do particular determination herein.When in use, spoil at the top of tunnel can be prevented by protective plate contact at the top of tunnel
Fall, meanwhile, can by 2 contact of top plate in protective plate far from the side at the top of tunnel, so as to which protective plate is fixed on tunnel top
Portion.
The method for carrying out roadway support to the gangue stopping device of disclosure embodiment below does simple elaboration:
The disclosure gear cash gear cash system, gangue stopping device and its carry out roadway support method, can by 2 contact of top plate in
At the top of tunnel, and spoil can be kept out towards goaf；Meanwhile can by 3 contact of side plate in tunnel side wall, thus prevent spoil from
Side wall enters tunnel.In the process, lifting column 1 can drive 2 synchronization lifting of top plate, adapt to different head-rooms, and can be right
Back 2 keeps supporting role, guarantees that back 2 is complete, guarantees worker safety, and top plate 2 passes through lifting column 1
Support, can enhance the ability of the lateral force resistance of the gangue stopping device；Side plate 3 can contact in tunnel side wall, be caving generation punching in spoil
When hitting power, it is possible to provide stable barrier force will not topple over, and at the same time, side plate 3 can be and then applicable with 2 synchronization lifting of top plate
In different tunnel Sidewall Heights, spoil is avoided to enter tunnel from side wall, and stable rubble side can be formed.By being pushed up to tunnel
The support of plate and rubble side forms roadway support.In addition, side plate 3 can be in integral structure with top plate 2 or substrate 6, so as to keep away
Manpower-free is laid with multiple barrier structures, and then multiple components is avoided to connect, and simplifies structure, and save the time, speeds up the work；
Meanwhile manual operation can be reduced, worker's amount of labour is reduced, mechanization process is improved.When in use, can also by protective plate contact in
At the top of tunnel, and then it can prevent spoil at the top of tunnel from falling, meanwhile, it can be by 2 contact of top plate at the top of protective plate is far from tunnel
Side forms Double-protection so as to which protective plate to be fixed at the top of tunnel.
Those skilled in the art after considering the specification and implementing the invention disclosed here, will readily occur to its of the disclosure
Its embodiment.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or
Person's adaptive change follows the general principles of this disclosure and including the undocumented common knowledge in the art of the disclosure
