The utility model discloses a novel holistic top beam suspending bracket, including a beam (1), a suspending top beam hydraulic support (6), an advancing support jack (3) and a sliding block. The utility model is characterized in that a slideway is arranged at the two sides of the beam (1) and the slideway on each side is respectively provided with a front slide block (5) and a back slide bock (2) which can slide along the slideway freely. The front slide block (5) and the back slide block (2) are respectively connected with the two ends of a connecting rod (4) by a hinge and are connected with the front and the back slide blocks of the adjacent bracket by a telescopic connecting rod (7). The cylinder rod of the advancing support jack (3) is hinged with the back slide block (2) by. The oil cylinder end of the advancing support jack (3) is hinged with the beam (1). The utility model has the advantages of convenient operation, fast advancing, high reliability and strong adaptability, improving the production efficiency and security greatly.
Description
Technical field
The utility model relates to the mine support apparatus field, especially a kind of novel overall back timber cantilever support that can effectively prevent the coal mine roof plate accident.
Background technology
In the Coal Production process, floods, fire, gas, coal dust, roof accident are called as five big disasters of serious threat coal miner personal safety.Old-fashioned hydraulic prop for moving suspended top beam results from eighties of last century eighties, and because of its inconvenient operation, production efficiency is low, and especially its safety is short of to some extent, is progressively eliminated.Occurred a kind of integral top beam sectional shelf-unit on the mine support Equipment Market in 2004, that its core technology is a back timber is square by being welded into steel plate, through two joists at work plane two in tow, finishes support moving to the rib direction.This support is when face pressure is big slightly, and because of joist is to be rigidly connected to be easy to make joist or beam body to deform, joist or beam body the card of spraining occurs after distortion occurring when moving frame, cause support can't move frame, cause support to use.
Summary of the invention
The utility model provides a kind of novel overall back timber cantilever support, can safeguard coal-face top board, isolate the goaf, for coal-face operating personnel and transporter, coal-winning machine provide safe operating space.
For achieving the above object, the technical solution of the utility model is as follows:
Include beam body, hydraulic prop for moving suspended top beam pillar, move frame jack and slide block, both sides at the beam body are respectively equipped with slideway, be respectively equipped with the front-slider and the rear slider that can be free to slide along slideway on every sideslip road, front-slider, rear slider are hinged with the connecting rod two ends respectively, front-slider, rear slider are hinged with front-slider, the rear slider of adjacent frame respectively by extensible link, the piston rod and the rear slider that move the frame jack are hinged, and the oil cylinder end that moves the frame jack is hinged on Liang Tishang.
Described adjacent two holes that the pin of extensible link is installed on the front-slider, rear slider of body of setting a roof beam in place are Long Circle;
Described adjacent two set a roof beam in place is provided with the compression spring in the front-slider, the extensible link between the rear slider of body.
The utility model is easy to operate, and it is rapid, safe and reliable to move frame, and compliance is strong, and production efficiency and safety are greatly improved.
Description of drawings
Fig. 1 is the structural representation of the utility model structure;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
Be an embodiment of the present utility model as depicted in figs. 1 and 2, beam body 1 is a box structure, the both sides of beam body 1 are symmetrical structure, be respectively equipped with the slideway that is free to slide for slide block, be separately installed with front-slider 5 and rear slider 2 on every sideslip road, hinged with connecting rod 4 respectively, front-slider 5 and rear slider 2 are connected as a single entity, realize the interlock of front-slider 5 and rear slider 2, the piston rod and the rear slider 2 that move frame jack 3 are hinged, the oil cylinder end and the beam body 1 that move frame jack 3 are hinged, front-slider 5, rear slider 2 by extensible link 7 respectively with the front-slider of adjacent frame A frame and C frame, rear slider is hinged.Set a roof beam in place body 1 of the B of entire working surface connects with adjacent frame A frame, the front-slider of C frame, rear slider by front-slider 5, rear slider 2 and extensible link 7, and 1 binding of the beam body on the entire working surface is become one.The hole that the pin 10 of extensible link 7 is installed on front-slider 5, the rear slider 2 is a Long Circle, beam body 1 has enough lifting spaces when moving frame with assurance, compression spring 8 can guarantee that extensible link 7 in time bounces back, between two pins 10, also be connected with theft-resistant link chain 9, when extensible link 7 is damaged, can guarantee the safety of beam body 1.
Move the frame method: all beam bodies 1 on the work plane (are A frame, B frame, C frame, D frame ...) supported by hydraulic prop for moving suspended top beam pillar 6, under the control that moves frame jack 3 and hydraulic control component reversal valve, hydraulic control one-way valve, move the piston rod retraction of frame jack 3, drive whole front-sliders, rear slider and extensible link and move forward a piston rod stroke.When mobile B sets a roof beam in place body 1, to support set a roof beam in place hydraulic prop for moving suspended top beam pillar 6 unloading of body 1 of B earlier, make the B body 1 of setting a roof beam in place be in relaxation state, front-slider 5, rear slider 2 and extensible link 7 are controlled at the set a roof beam in place fall of body 1 of B about 80mm, make itself and hydraulic prop for moving suspended top beam pillar 6 be suspension status, after hydraulic prop for moving suspended top beam pillar 6 bottoms are left about base plate 200mm, to the set a roof beam in place oil cylinder that moves frame jack 3 feed flow simultaneously of body 1 both sides of B, make its piston rod outwards move a piston rod stroke, other integral top beam cantilever support (A frame on the work plane, the C frame, the D frame ...) the oil cylinder that moves the frame jack by the hydraulic control one-way valve locking, promptly 4 slide blocks with the extensible link 7 joining adjacent framves of B frame form 4 fixed support points, extensible link 7 is at the front-slider 5 of B frame, rear slider 2 and A frame, the front-slider of C frame, can only in perpendicular to a plane of beam body 1, rotate up and down in the rear slider, so front-slider 5 of B frame, rear slider 2 has also formed 4 fixing strong points of fore-and-aft direction, the piston rod and the rear slider 2 that move frame jack 3 are hinged, beam body 1 is hinged with the oil cylinder end that moves frame jack 3, when the piston rod that moves frame jack 3 stretches out a stroke, promptly drive beam body 1 and moved forward a piston rod stroke.Hydraulic prop for moving suspended top beam pillar 6 is risen after body 1 moves frame and puts in place when B sets a roof beam in place, more corresponding hydraulic control component reversal valve is got to meta, make the jack 3 of hydraulic control one-way valve locking both sides, promptly finish the B frame and move frame work.Finish the work by that analogy C frame on the face, D frame ... the frame work that moves.
