Abstract
The utility model relates to a coal mine underground crossheading forepoling supporting frame, which consists of a left frame body and a right frame body with the same structure, wherein each frame body consists of a front frame, a middle frame and a back frame which all consist of a top beam, a base and hydraulic upright posts; the middle frame is connected with the top beam between the front frame and the back frame and the base between the front frame and the back frame by using a hinged structure; the top beam and the base of the front frame are hinged with each other by using a hydraulic prop; the top beam and the base of the middle frame are hinged with each other by using a front hydraulic prop and a back hydraulic prop, and form a stabilizing mechanism by using a four bar mechanism; the top beam and the base of the back frame are hinged with each other by using a hydraulic prop; and finally, the left frame body and the right frame body are hinged into a whole by a hydraulic jack on the middle frame. The utility model has the advantages that: during advanced gallery supporting, the coal mine underground crossheading forepoling supporting frame is arranged on two sides of a working surface reversed loader to replace the original single prop so as to realize the functions of pushing the reversed loader and an end supporting frame.
Description
Technical field
The utility model relates to coal mine downhole crossheading and uses support apparatus, is specifically related to a kind of advanced support rack of coal mine downhole crossheading.
Background technology
In the coal mine downhole crossheading temporary lining at present, generally adopt individual prop to carry out temporary lining.Because the hydraulic support of individual prop and coal-face is mismatched, so labour intensity is big.
The utility model content
The purpose of the utility model is to propose a kind of advance support rack that is used in combination with the work plane fully-mechanized mining equipment.
A kind of advanced support rack of coal mine downhole crossheading; It by about two identical support bodys of structure form; Each support body is made up of side arm, middle frame and after-frame; Side arm, middle frame and after-frame all are made up of back timber, base and hydraulic vertical prop, and middle frame adopts articulated structure to be connected with back timber and middle frame between forward and backward with base between forward and backward; Wherein the back timber of side arm and base are hinged with a hydraulic prop; The back timber and the base of middle frame adopt forward and backward two hydraulic props hinged, and adopt quadric chain as stabilizing mechanism; The back timber of after-frame and base adopt a hydraulic prop hinged, last about two support bodys be hinged to one by the hydraulic jack on the middle frame.
Temporary lining when making somebody a mere figurehead the top for realizing moving, the back timber of side arm is the extensible canopy structure.
The utility model has the advantages that, when ultra roadway support, the utility model is arranged in work plane elevating conveyor both sides, replace original individual prop, realize passing the function of elevating conveyor and face end support.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the lateral view of Fig. 1.
Label 1 is an extensible canopy in the accompanying drawing, and 2 is front-axle beam, and 3,4 is hydraulic vertical prop, and 5 is central sill, and 6 is quadric chain; 7,8 is hydraulic vertical prop, and 9 is the back rest, and 10 is rear base, and 11 is middle base; 12 is preceding base, and 13 is left half, and 14 is right half, and 15,16 is hydraulic jack.
The specific embodiment
With reference to Fig. 1, like Fig. 2 the utility model is further specified: as seen from the figure, it is made up of side arm, middle frame and after-frame three parts.Be made up of the identical left and right sides two parts of structure for every, as shown in Figure 1 is that left half also is right half, and left and right two parts utilize hydraulic jack 15 to fix with 16 or hinged respectively, constitute a frame integral body.Side arm is by extensible canopy 1, and front-axle beam 2, hydraulic vertical prop 3 and preceding base 12 are formed; Middle frame is made up of central sill 5, quadric chain 6, hydraulic vertical prop 4, hydraulic vertical prop 7 and middle base 11, and after-frame is made up of the back rest 9, hydraulic vertical prop 8 and rear base 10; All adopt articulated structure between every hydraulic vertical prop and the back timber base; In back timber and base between frame and forward and backward all adopt articulated structure.
Claims (2)
