The top beam of a filling support is supported through uprights, and is connected with a base through a stabilizing mechanism; the top beam and a hinged tail beam are connected through a hinge pin, one end of a tail beam jack is hinged with the top beam, and the other end of the tail beam jack is hinged with a hinged tail beam; the uprights are placed on the base; a separating mechanism is arranged on the tail of the base; the stabilizing mechanism consists of an oblique beam, a front connecting rod and a rear connecting rod; the front row of uprights are located in front of the stabilizing mechanism so as to support the front part of the top beam, and the rear rows of uprights are located behind the stabilizing mechanism so as to support the rear part of the top beam; one end of an ascending jack is hinged with the base, and the other end of the ascending jack is hinged with a segregation board. The hydraulic support has the advantages of being applicable to filling various pastes into the working surface; furthermore, in the process of mining coal with filling, a support to-be-filled area can be conveniently and quickly obtained so as to set a filling separator; meanwhile, under the premise of guaranteeing to effectively seal the separator and prevent the filling paste from flowing into the working surface, the working time for filling preparation can be shortened, the manual labor can be reduced, and the paste filling working efficiency can be improved.
Description
Technical field
The utility model relates to a kind of support apparatus of coal-face, particularly a kind of hydraulic support for coal mine paste filling exploitation.
Background technology
Conventional hydraulic support major function is supporting roof of coal face, and in paste body filling coal mining process, carries out filling isolation preparation in the goaf that workman need form after support moves frame.This requires paste filling hydraulic bracket having outside the function of supported face top board, also needs to carry out supporting management to moving the filling area for the treatment of producing after frame, thereby provides safe working space for filling preparation.Apply existing support apparatus and can not meet filling coal mining supporting requirement, also need to take in addition artificial measures, carry out supporting management as manually set up the measures such as wood point post or supporting monomer column to treat filling area.After filling preparation completes, need reclaim the support apparatus of having set up.The too much manual work of whole filling isolation set-up procedure causes filling coal mining mechanization degree low, and whole work efficiency is difficult to improve.
Patent CN 102042026A discloses a kind of filling hydraulic support with tail boom.This support is after moving frame, and when workman carries out filling preparation, support tail boom can overturn and lift supporting roof.After filling preparation completes, tail boom is regained vertical with back timber, and now tail boom can be used as division board.But tail boom top is to take filling quarantine measures key position.Described in this patent, the problem of support is, it is only after tail boom upset is regained, and workman could isolate preparation to this tail boom top.Roof timbering measure now still must be manually set, and workman just can carry out the isolation preparation work of tail boom top.Therefore, above-mentioned this hydraulic support could not solve the filling area supporting problem for the treatment of.
Patent CN102269010A discloses a kind of integrated paste filling hydraulic bracket.This support comprises side arm and after-frame.After-frame back timber afterbody is provided with back bar, and this back bar is fixed, in the time carrying out paste body filling, cannot regain, and certainly will have influence on paste body filling and connect top effect.
In sum, under the prerequisite of assurance filling effect, combine and adopt in technology at paste body filling at present, still exist and treat filling area roof timbering problem of management.
Utility model content
The purpose of this utility model is that a kind of hydraulic support for coal mine paste filling exploitation will be provided, and solution preparation time before coal mine filling is longer, and hand labor intensity is large, the problem that efficiency is lower.
The technical scheme that realizes the purpose of this utility model employing is as follows:
This coal mine filling support comprises: back timber, stabilizing mechanism, column, hinged tail boom, tail boom jack, interrupter, rising jack and base; Back timber is by upright supports; Back timber is connected with base by stabilizing mechanism; Between back timber and hinged tail boom for bearing pin is connected; Tail boom jack one end and back timber are hinged, and the tail boom jack other end and hinged tail boom are hinged; Base is used for laying described column; Base afterbody is equipped with interrupter; Stabilizing mechanism is made up of cant beam, front rod and back link; Totally four, column, two is that a component is two groups, is respectively front-seat column and rear row's column; Front-seat column is positioned at stabilizing mechanism front, supporting top beam front portion, and rear row's column is positioned at stabilizing mechanism rear, supporting top beam rear portion; Interrupter comprises division board and lower division board, and rising jack one end and base are hinged, and on the rising jack other end, division board is hinged.
Described hinged tail boom is box-structure, or frame construction.
Described upper division board is box-structure, or frame construction.
Described lower division board is box-structure, or frame construction.
Described stabilizing mechanism is quadric chain.
Beneficial effect, owing to adopting such scheme, in the time carrying out filling isolation preparation, only hinged tail boom 4 need be routed up to supporting treats filling area, workman can carry out filling isolation preparation in the scope that has supporting, manually treats filling area support work without workman.Before paste body filling, hinged tail boom 4 rotations are regained, and do not affect support afterbody packing job, and have guaranteed paste body filling effect.It is longer to have solved before coal mine filling the preparation time, and hand labor intensity is large, and the problem that efficiency is lower has reached the utility model object.
Advantage: in filling coal mining, quick-setting is treated filling area supporting, is guaranteeing to treat filling area roof timbering, under the prerequisite that prevents from treating to fall filling area cash hurts sb.'s feelings, cancels the artificial support work of workman, reduces hand labor, improves filling integral operating efficiency.
