Abstract
The utility model relates to the field of coal mine underground fully mechanized working face support equipment, in particular to a two-column shield type hydraulic support for filling and mining, which solves the problem that supporting intensity and supporting height of an existing hydraulic support cannot meet requirements, reciprocating motion of a telescopic beam is unstable and the like. The two-column shield type hydraulic support for the filling and the mining comprises a base, a top beam and a column. A four-bar linkage mechanism formed by a front connecting bar, a rear connecting bar and a shield beam is arranged between the base and the top beam, a telescopic beam and a telescopic oil cylinder which are matched with the top beam are arranged at the front end of the top beam, a pushing rod and a pushing oil cylinder are arranged in the base in penetrating mode, a pull-shift oil cylinder is arranged on the rear portion of the base, the rear end of the top beam is hinged to a tail beam, dovetail grooves are arranged on two side edges of the telescopic beam respectively, and projections matched with the dovetail grooves are arranged on two sides of the inner portion of the top beam. The two-column shield type hydraulic support for the filling and the mining is simple in structure, reasonable in design, convenient to use, safe and reliable, can fully meet requirements of a filling hydraulic support for supporting strength and supporting height, solves the problem of simultaneous operation of underground coal mining and filling operation, and can be widely applied to underground mining of a coal mine.
Description
Technical field
The utility model relates to underground fully-mechanized mining working support apparatus field, colliery, is specially a kind of filling mining two column protected type hydraulic support.
Background technology
In the coal mining, after fully-mechanized mining working advanced, the work plane rear portion formed the goaf; The goaf can progressively collapse along with the propelling of work plane; Cause the mine geology structural change, even face of land ground settlement, above ground structure, road, water body are damaged; Thereby cause China's " three times " to press the coal recovery ratio low, resource can't make full use of.The flyash discharge value was huge during a large amount of spoils that produce in the coal production process simultaneously, colliery power plant for self-supply produced, and can not effectively utilize.Implement spoil, flyash filling mining, both can all be backfilling into the goaf to spoil that is produced in the Coal Production process and discarded object flyash, can reduce surface settlement to greatest extent again, the safety and stability of arable land, protection ground and building.Realize fully-mechanized mining working spoil, flyash filling mining, need constantly to carry spoil, flyash filler that the packing job operating personnel's that need protection simultaneously safety just needs to adopt the filling hydraulic support to the goaf.And existing filling hydraulic support adopts four post support shield type frame type; The structure design that is connected of back timber and its front end extensible canopy is unreasonable; It is unstable to cause extensible canopy to move back and forth; Effective support intensity is relatively poor, and the filling hydraulic support provide long supporting can't be effectively for the bashing territory, can't realize mining and filling operation such as carries out simultaneously at problem.
Summary of the invention
The utility model moves back and forth instability, can't long supporting is provided for effectively the bashing territory for the extensible canopy that solves existing filling hydraulic support employing; Can't realize mining and filling operation such as carries out simultaneously at problem, a kind of filling mining two column protected type hydraulic support is provided.
The utility model is to adopt following technical scheme to realize: a kind of filling mining two column protected type hydraulic support; Comprise base, back timber, be connected with column between base and the back timber, the quadric chain that is made up of front rod, back link and caving shield also is set between base and the back timber; Be provided with balancing cylinder between caving shield and the back timber; The back timber front end is provided with extensible canopy and the telescopic oil cylinder that cooperatively interacts with it, runs through in the base pusher rod to be set and to pass oil cylinder, and the base rear portion is provided with to draw moves oil cylinder; Top beam rear end is hinged with tail boom; Be provided with short column between back timber and the tail boom, the innovative point of the utility model is that two sides of extensible canopy offer dovetail groove respectively, and the inner both sides of back timber are respectively equipped with the projection that cooperatively interacts with dovetail groove.Adopt this form of structure, can guarantee that extensible canopy operates steadily reliably, effectively the inbreak of control bracket front end top board.
Said drawing moved oil cylinder and drawn for two flexible double actings and move oil cylinder, and stroke reaches 1800mm, and the operating position of template is isolated in the control filling, is to realize mining and critical component that filling operation is carried out simultaneously.
Compared with prior art, the utility model is simple in structure, and is reasonable in design; Easy to use, safe and reliable, adopt two column protected type frame type; Can satisfy the requirement of filling hydraulic support to supporting intensity and supporting height fully, extensible canopy operates steadily reliably, effectively the inbreak of control bracket front end top board; Solve the difficult problem that down-hole coal excavation and filling operation are carried out simultaneously, can be widely used in coal mine retrofilling exploitation instructions for use.
