The utility model relates to a filling hydraulic support frame for the backfill of a coal mine and belongs to a hydraulic support frame for a coal mine. An externally-telescopic upper extension box is installed on an isolation plate; tail beam oil cylinders are installed on a top beam, one end of each tail beam oil cylinder is hinged with the top beam, and the other end of the tail beam oil cylinder is hinged with a telescopic tail beam; the telescopic tail beam is embedded and installed at the tail part of the top beam; diagonal-supporting oil cylinders are installed on the front side of the isolation plate, one end of each diagonal-supporting oil cylinder is hinged with a base of the isolation plate, and the other end of the diagonal-supporting oil cylinder is hinged with the isolation plate; telescopic oil cylinders are installed on the front side of the isolation plate, one end of each telescopic oil cylinder is hinged with the isolation plate, and the other end of the telescopic oil cylinder is hinged with the upper extension box; the upper extension box is embedded and installed at the upper part of the isolation plate; two tail beam oil cylinders, two diagonal-supporting oil cylinders and two telescopic oil cylinders are symmetrically arranged respectively; a four-connecting rod mechanism and an upright post are connected between the top beam and the base of the support frame; the upright post is positioned at one end of the top beam; and the four-connecting rod mechanism is positioned in the middle position of the top beam. The filling hydraulic support frame has the advantages that the isolation plate can adapt to the height change of a working surface, and the upper extension box can be horizontally supported by the telescopic tail beam under the protection function to optimize and improve the stress conditions of the isolation plate.

Description

The filling hydraulic support of colliery backfill
Technical field
The utility model relates to a kind of coal mine hydraulic supporting, the filling hydraulic support of particularly a kind of colliery backfill.
Background technology
At present, paste body filling usually need be built divider wall in the filling coal mining technology, and the divider wall construction method mainly contains two kinds: a kind of is that divider wall is built in manual work, and a kind of is at the support afterbody division board to be installed.Division board mainly contains two types: one type is the overlapping division board; Last division board in the overlapping division board is installed on the back timber; The frame operation need be fallen when support and top board seam crossing are done auxiliary seal; Fall the empty top of frame operation increase work plane scope, increased support and propped up the top number of times repeatedly, bring potential safety hazard to coal-face; Another kind of is telescopic division board, and the workman need treat that the filling area does a post and support when telescopic division board rear operating; Mounting or dismounting point post supports and has increased the working time, has reduced filling operation efficient, after telescopic in addition division board top box stretches out; Top box does not have level to be supported; This makes that stressing conditions worsened when division board and support bore lotion pressure, is difficult to effectively isolate filling area and work plane, also comes hidden danger for producing safety belt.
The utility model content
The purpose of the utility model is the filling hydraulic support that the backfill of a kind of colliery will be provided, and division board and support are difficult to effectively isolate the problem of filling area and work plane when solving in colliery backfill.
The purpose of the utility model is achieved in that this filling hydraulic support comprises: back timber, quadric chain, column, flexible tail boom, tail boom oil cylinder, on stretch case, telescopic oil cylinder, division board, diagonal brace oil cylinder, division board base and bracket base; Division board base and bracket base are hinged; Division board and division board base are hinged; Stretch case on telescopic in being equipped with on the division board; The tail boom oil cylinder is installed on the back timber; Tail boom oil cylinder one end and back timber are hinged, and an end and flexible tail boom are hinged, the flexible embedded back timber afterbody that is installed in of tail boom; The division board installed in front has the diagonal brace oil cylinder; Diagonal brace oil cylinder one end and division board base are hinged, and an end and division board are hinged; The division board installed in front has telescopic oil cylinder; Telescopic oil cylinder one end and division board are hinged, an end and on to stretch case hinged, on stretch the embedded division board top that is installed in of case; Tail boom oil cylinder, diagonal brace oil cylinder, telescopic oil cylinder are two, are symmetrical set; Between back timber and bracket base, be connected with quadric chain and column, column is positioned at an end of back timber, and quadric chain is positioned at the centre position of back timber.
Beneficial effect is: owing to adopted such scheme, isolate preparation when beginning in filling, the division board of filling hydraulic support need not support integral body and falls frame because have and stretch case and can do lifting action by independently relative support; In addition in stowing operation; The flexible tail boom 4 of support stretches out the top of stretching case in the support, optimizes the whole force-bearing situation of division board, before the paste body filling; The flexible tail boom of filling hydraulic support can provide effective shielding of preparing between the filling area, is convenient to the workman and carries out filling preparation.Division board and support are difficult to effectively isolate the problem of filling area and work plane when having solved in colliery backfill, have reached the purpose of the utility model.
Advantage: but the division board independent-lifting need not to fall body frame operation and just can adapt to face height and change, flexible tail boom under the function of shielding again can on stretch case horizontal support be provided, optimization improves the force status of division board.
