Description
Technical field
The invention belongs to underground coal mine coal excavation apparatus field, more particularly in the case of roadway's sides pressure is yielding greatly
A kind of automatic moving type forepoling hydraulic support with side guard plate.
Background technology
In process of coal mining, with the exhaustion of the continuous exploitation shallow-layer coal resources of coal resources, so will
The exploitation to deep coal resources is carried out, is melted however as deep and adopted, it has to the problems such as increasing severely in face of mine pressure, especially
In some Deep Mines, roadway workface deformation is serious, and two help serious breakoff phenomenon occur, and roof and floor also occurs not
With the destruction of degree, particularly it is even more in the advanced section of roadway workface and serious roadway deformation occurs, has a strong impact on working face
Propulsion, influences normal coal work, even more in the presence of serious potential safety hazard, influences the personal safety of workman, and to tunnel
Equipment produces destruction, so as to cause huge economic loss.
But in numerous advanced hydraulic supports, few equipment that roadway's sides are carried out with effective support, substantially all
That top board base plate is considered, however deforming in face of roadway's sides, it is raised, broken situations such as, without considering well and solve.
Roadway's sides deform very big on the influence of the section in tunnel, influence normal ventilation section, influence normal pedestrian and material
Transport etc..So being only also carried out supporting to roadway's sides, the supporting with roof and floor forms a support system for closure, ability
It is real that effective supporting is played to the advanced section in tunnel, reduce destruction of the pressure to tunnel.
The content of the invention
Part, super it is an object of the invention to provide a kind of automatic moving type with side guard plate in view of the shortcomings of the prior art
Preceding hydraulic support, during the advance support in coal work tunnel, realizes the effective support to roadway's sides, can reduce
The deformation failure of roadway's sides.
The purpose of the present invention is achieved through the following technical solutions：
A kind of automatic moving type forepoling hydraulic support with side guard plate, including two pack supports, wireless monitoring device and hydraulic system,
The hydraulic system is controlled by default to the operation order of hydraulic support, controls the operation of whole system, wherein：
Set before and after two pack support, the base being symmetrical set and back timber, connection back timber and base are included per pack support
Quadric chain, a pair of synchronous hydraulic telescopic columns being arranged between base and back timber, between the symmetrically arranged back timber
Connected by one group of hydraulically extensible oil cylinder group and base between, liquid is passed through between the base of front and rear two pack supports for setting
Pressure telescopic oil cylinder correspondence is connected；
The support also includes top side side board and bottom side side board, and the top side side board is by some groups of water setting up and down
Flat jack group is connected to back timber outside, and the bottom side side board is connected to by some groups of level jack groups setting up and down
Chassis outer side；
The wireless monitoring device include being separately positioned on pressure sensor in level jack and synchronous hydraulic telescopic column,
It is arranged on shock sensor and wireless communication apparatus on base.
Further, the described every group hydraulically extensible oil cylinder being arranged between back timber and base between includes at least three liquid
Compressing cylinder.
Preferably, it is described connection top side side board and back timber level jack group and be connected bottom side side board and base
The quantity of level jack group be at least four groups.
Further, the base two ends are wedge structure.
Further, spacing slide rail is additionally provided with the corresponding base of front and rear two pack supports, is set on the slide rail
The limit telescopic beam that cross section is " Jiong " shape is equipped with, the limit telescopic beam covers on hydraulically extensible oil cylinder top.
The present invention compared with the prior art, with advantages below and beneficial effect：
First, the present invention effectively can carry out supporting to roadway's sides, effectively can help to protect to two, it is to avoid deformation is made
Into destruction, while can with back timber, base engagement formed one closure support system, enhance the branch to tunnel globality
Shield, while making the globality intensity in tunnel also improve, is more beneficial for safety in production；
2nd, lateral wall plate is connected by jack with support, it is possible to achieve lateral wall plate transversal stretching, can when support is moved and is supported
Shunk and stretching, extension with corresponding, while support can be realized, from moving, so as to use manpower and material resources sparingly, meeting high-yield and high-efficiency working face
The requirement in face；
3rd, in level jack and synchronous hydraulic telescopic column pressure sensor and the shock sensor on base
The wireless monitoring device constituted with wireless communication apparatus can be to the pressure suffered by back timber, top side side board, bottom side side board
Carry out real-time monitoring and data are sent to outside well by wireless communication apparatus, staff is carried out the working condition of support
Monitoring, when support is subject to larger STRESS VARIATION, can be adjusted pressure release or to underworkings lateral wall to support in time
Reinforcement operation etc. is carried out with top board, it is ensured that the safe working in colliery.
