Abstract
The invention discloses an underground coal mine crossheading advanced support, which consists of a left support body and a right support body with the same structures, wherein each support body consists of a front support, an intermediate support and a rear support; the top between the intermediate support and the front support and the top between the intermediate support and the rear support are connected with a pedestal between the intermediate support and the front support and a pedestal between the intermediate support and the rear support by means of hinged structures; and finally the left support body and the right support body are hinged into a whole by a hydraulic jack on the intermediate support. The underground coal mine crossheading advanced support has the advantages of realizing the function of moving a reversed loader and a face-end support by arrangement of the underground coal mine crossheading advanced support on both sides of the reversed loader of a working surface instead of the prior single prop under the condition of advanced roadway support.
Description
Technical field
The present invention relates to the coal mine downhole crossheading support apparatus.
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.
Summary of the invention
The objective of the invention 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 and the dark and middle frame in the top between forward and backward adopt articulated structure to be connected 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.
Advantage of the present invention is, when super roadway support, the present invention is arranged in work plane elevating conveyor both sides, replaces original individual prop, realizes passing the function of elevating conveyor and face end support.
Description of drawings
Further specify structure of the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is a front view of the present invention;
Fig. 2 is the lateral view of Fig. 1.
Marginal data: 1---extensible canopy, 2---front-axle beam, 3,4---hydraulic vertical prop, 5-central sill, 6---quadric chain, 7,8---hydraulic vertical prop, 9---the back rest, 10---rear base, 11---middle base, 12---preceding base, 13---left half, 14---right half, 15,16---hydraulic jack
The specific embodiment
With reference to Fig. 1, the present invention is further described as Fig. 2: as seen from the figure, it is made up of side arm, middle frame and after-frame three parts.Form by the identical left and right sides two parts of structure for every, as shown in Figure 1 be that left half also is right half, left and right sides two parts are hinged with hydraulic jack 15 and 16, 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)
1, a kind of advanced support rack of coal mine downhole crossheading, it is characterized in that, 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 and the dark and middle frame in the top between forward and backward adopt articulated structure to be connected 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.
2, advanced support rack of coal mine downhole crossheading as claimed in claim 1 is characterized in that, described side arm back timber is the extensible canopy structure.
