Abstract
The invention provides a hydraulic support with filling and leakage-preventing function, belonging to the fully-mechanized mining supporting equipment. The hydraulic support with filling and leakage preventing function comprises a front upright, a rear upright, a top beam and a pedestal. The pedestal is in a semi-open bottom box structure and is provided with a bottom lifting mechanism and a bottom adjusting mechanism; the top beam is in an integral top beam structure and is articulated with a tail beam on the rear part; the lower part of the tail beam and the lower part of the top beam are connected with a hydraulic cylinder; the hydraulic cylinder can push the tail beam out so that the tail beam and the top beam are arranged on the same plane to serve as supporting top plates; when the tail beam recovers under the action of the hydraulic cylinder and forms a right angle with the top beam, the tail beam serves as an upper isolation plate; the middle part of the tail beam is provided with a material tube connection hole; the rear part of the pedestal is raised integrally to form a lower isolation plate; and the upper isolation plate lapped with the lower isolation plate to form an isolation wall. The hydraulic support has enough support strength when being used for coal mining, the isolation wall can be formed on the tail part of the hydraulic support, and the hydraulic support can fill the rear mined area when being pushed forwards.
Description
Technical field
The present invention relates to a kind of comprehensive mechanical coal mining equipment.
Background technology
At present, to filling in the coal mine gob be the basic demand in field, colliery.When filling, need take divider wall the goaf is sealed, this kind mode is cumbersome, and operating efficiency is lower.Hydraulic support is the key equipment of comprehensive mechanical coal mining.Present hydraulic support only has the function of support shield, can not carry out shutoff to the filling isolated area, has reduced operating efficiency.Therefore, a kind of hydraulic support with filling isolation features of research and development has just become the task of top priority.
Summary of the invention
The present invention is directed to defective of the prior art, a kind of hydraulic support with filling drip-preventing function is provided.This hydraulic support not only can guarantee to have enough supporting intensities when mining, and the afterbody of this hydraulic support can form divider wall, also can carry out filling to the goaf at rear portion after hydraulic support is pushed ahead, and need not to take in addition divider wall.
Its technical solution is: a kind of hydraulic support with filling drip-preventing function, column, back timber and base before and after comprising, base adopts half bottom opened box-structure, be equipped with bottom raising mechanism and end regulating mechanism, back timber adopts the integral top beam structure, the back timber rear portion is hinged with tail boom, the bottom of described tail boom and the bottom of back timber are connected with hydraulic cylinder, hydraulic cylinder tail boom can be released with back timber in one plane as supporting roof, division board in the conduct when withdrawal under the effect of tail boom at hydraulic cylinder meets at right angles state with back timber, the middle part of tail boom offers material pipe connecting hole; Whole high the rising in the rear portion of described base forms division board down; Last division board and following division board overlap mutually, constitute divider wall.
The same side of above-mentioned back timber, tail boom and base is provided with the active side backplate.
The invention has the beneficial effects as follows: under the condition that can guarantee hydraulic support stability, can also satisfy the needs of filling leakproof, and filling connects the top rate and reaches more than 95%.Hydraulic support of the present invention is when mining, and tail boom is positioned on the same horizontal plane active support filling area top board stretching out under the effect of hydraulic cylinder with back timber; When filling, the tail boom withdrawal, with the back timber state that meets at right angles, become and go up division board, last division board and top beam rear end, following division board overlap mutually, constituted the divider wall with good drip-preventing function, and the same side of back timber, tail boom and base are provided with the active side backplate, guaranteed that adjacent hydraulic support contacts side surfaces is tight, prevented that slip from revealing between two hydraulic supports.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details, as shown in Figure 1, a kind of hydraulic support with filling drip-preventing function adopts high-strength steel sheet to make, and hydraulic system adopts this manually big flow control system.Front column 1, rear column 2 adopts preposition positive four connecting rod forms, and front and rear row column spacing is rationally adjusted, and provides the space for the layout of filling pipeline and whole reach and personnel walk; Base 3 adopts half bottom opened box-structure, and preceding gap bridge adopts the high-strength steel sheet of 100 millimeters of thickness, is equipped with bottom raising mechanism and end regulating mechanism, and whole high the rising in the rear portion of base forms division board 4 down, and a side of following division board 4 is provided with active side backplate 5.Back timber 6 adopts overall structure, and the rear portion is hinged with tail boom 7, and the same side of back timber 6 and tail boom 7 is provided with active side backplate 8.The bottom of tail boom and back timber is connected with hydraulic cylinder 9, tail boom 7 can stretch out under the effect of hydraulic cylinder 9 with back timber 6 and form supporting roof at same horizontal plane, when tail boom 7 is regained and back timber 6 states of meeting at right angles form division board, the middle part of tail boom 7 offers material pipe connecting hole, when needing to arrange filling pipe, filling pipe is connected with material pipe connecting hole, material pipe connecting hole can be blocked when not needing to arrange filling pipe.
The present invention adopts the direct contact seal structure of steel plate, and top and back timber, bottom and base top overlap joint were realized contact seal jointly when back timber and tail boom adopted flexible board-like line contact sealing structure tail boom to regain; Hermetically-sealed construction can adapt to maximum bow adopt 10 the degree requirements.The back timber of adjacent hydraulic support, tail boom and base active side backplate mutual extrusion are fitted, and realize sealing.Base active side backplate is designed to maze-type structure, forms labyrinth sealing with top body plate, avoids retractable one-tenth flute profile spillage passage, is close to sealing between side guard board when guaranteeing the allowed band deflection.
Certainly, the present invention comprises and is not limited to the foregoing description, so long as those skilled in the art does not have a creationary improvement to what the present invention made, all within the protection domain of patent of the present invention.
Claims (2)
1. hydraulic support with filling drip-preventing function, column, back timber and base before and after comprising, base adopts half bottom opened box-structure, be equipped with bottom raising mechanism and end regulating mechanism, back timber adopts the integral top beam structure, the back timber rear portion is hinged with tail boom, the bottom that it is characterized in that described tail boom and back timber is connected with hydraulic cylinder, hydraulic cylinder tail boom can be released with back timber in one plane as supporting roof, division board in the conduct when withdrawal under the effect of tail boom at hydraulic cylinder meets at right angles state with back timber, the middle part of tail boom offers material pipe connecting hole; Whole high the rising in the rear portion of described base forms division board down; Last division board and following division board overlap mutually, constitute to have divider wall.
