Slide unit is arranged on saddle by " work " shape slide rail, and the both sides of " work " shape slide rail are the spacing slideway for accommodating pulley,
Pulley connects slide unit and causes to leave gap between slide unit and " work " shape slide rail upper surface by support, slide unit connection transverse hydraulic
Cylinder, movement of the slide unit relative to saddle is realized by transverse hydraulic cylinder.
The bottom of slide unit is provided with "eight" shape stay fork, the lower end of "eight" shape stay fork puts in and is arranged on " work " shape
In the oblique groove of slide rail side, gap is left between the lower end of "eight" shape stay fork and the cell wall of oblique groove, " eight " word
Gap between the lower end of shape stay fork and the bottom of oblique groove is less than the gap between slide unit and " work " shape slide rail upper surface.
"eight" shape stay fork uses elastic piece structure.
Advantageous effect：The utility model provides the cover frame that a kind of underground coal mine removes hydraulic support, and it utilizes working face
The emulsion that emulsion pump is provided is power source, and the manipulation valve being installed on shield support base by control is made on cover frame
Various jack actions, complete support drop frame, movement, supporting roof work, to adapt to the requirement of working face striking.
Which solve fully-mechanized mining working surface hydraulic support needs personnel nearby to play monomer, log supporting in the demolishing process of underground
The job safety coefficient that is brought during top board operation is low, labor strength is big, the problem more than waste of materials, using shield support branch
Shield empty top zone top board can safe, quick striking, brought to down-hole combined mining working hydraulic support dismounting work larger
It is convenient, improve operating efficiency.

Fig. 2 is the top view of saddle；
Fig. 3 is the side view of saddle.
Specific embodiment
As shown in figure 1, utility model provides the cover frame that a kind of underground coal mine removes hydraulic support, the support includes saddle
1st, slide unit 2, base 3, back link 4, front rod 5, caving shield 6, back timber 7, balance jack 8, hydraulic vertical prop 9, advancing jack
10 and carried bottom jack 11；
Base 3 is arranged on slide unit 2 by slide rail, and can be moved relative to slide unit 2, and slide unit 2 is arranged on support by slide rail
On platform 1, one end of back timber 7 is flexibly connected with the upper end of caving shield 6, and the lower end of caving shield 6 is flexibly connected with back link 4, preceding company
Bar 5 is connected to the middle part of caving shield 6, and back link 4 and front rod 5 are movably arranged on base 3；
Caving shield 6, back link 4 and front rod 5 form F shape structures, and balance thousand is connected between caving shield 6 and back timber 7
Jin top 8, back timber 7 is withstood in the three-legged structure of formation activity between caving shield 6, back timber 7 and balance jack 8, the upper end of hydraulic vertical prop 9
Bottom, the lower end of hydraulic vertical prop 9 set on the base 3；
Advancing jack 10 is horizontal jack, and the rear portion fixing end of advancing jack 10 is arranged on slide unit 2, passage thousand
Front portion god's contracting end connect base 3 on jin top 10, is moved by the flexible promotion base 3 of advancing jack 10 relative to slide unit 2；
Carried bottom jack 11 is upright jack, and the bottom fixing end of carried bottom jack 11 is arranged on slide unit 2, in base
" 7 " character form structure 12 being made up of cross bar and vertical pole is provided with 3, " 7 " character form structure 12 protrudes from base 3, carried bottom jack
The cross bar of " 7 " character form structure is withstood at 11 top god contracting end, by carried bottom jack 11 it is flexible head on base 3 and do move down
It is dynamic.
Slide unit 2 is arranged on saddle 1 by " work " shape slide rail 14, and the both sides of " work " shape slide rail are the spacing of receiving pulley 13
Slideway, primarily to saving vertical direction spatial in the form of this slideway；
Pulley 13 connects slide unit 2 and causes to leave gap between slide unit 2 and " work " shape slide rail upper surface by support, this
The effect of gap is, when slide unit 2 bears excessive power, the support for connecting pulley 13 is possible to fracture, and such slide unit 2 will be direct
Fall and play a part of on " work " shape slide rail 14 buffering,
The connection transverse hydraulic of slide unit 2 cylinder 17, movement of the slide unit 2 relative to saddle 1 is realized by transverse hydraulic cylinder 17.
The bottom of slide unit 2 is provided with "eight" shape stay fork 15, the lower end of "eight" shape stay fork 15 puts in and is arranged on
In the oblique groove of the side of " work " shape slide rail 14, between being left between the lower end of "eight" shape stay fork 15 and the cell wall of oblique groove
Gap, the gap between the lower end of "eight" shape stay fork and the bottom of oblique groove is less than slide unit 2 and " work " shape slide rail upper surface
Between gap, the main branch for being exactly to be connected when the power excess load that slide unit 2 bears pulley 13 of effect of "eight" shape stay fork
Frame is possible to fracture, and at this moment, "eight" shape stay fork will be inserted directly into the bottom of oblique groove, and because "eight" shape support
Gap between the lower end of fork and the bottom of oblique groove is less than the gap between slide unit 2 and " work " shape slide rail upper surface, so
"eight" shape stay fork can first realize support buffering, and when "eight" shape stay fork also fractures, slide unit 2 can just fall " work " shape
Further buffering is realized on slide rail 14.So will avoid what is be directly pressed down because of the back timber 7 brought without cushioning supportive
Problem, back timber 7 is directly pressed down can bring very big danger, and pass through to buffer the pressure for slowing down back timber 7 twice, and then quickly adopt
Take remedial measure.In order to increase buffering effect, "eight" shape stay fork can be using the resilient elastic piece structure of tool, its structure class
It is similar to the arc-shaped shock-absorbing piece on lorry.
When using, saddle 1 is dragged to specified location, the bottom of saddle 1 can set wheel or crawler belt, here no longer
Repeat, after reaching appointed place, the fixation of saddle 1 is realized by the hydraulic support leg 18 of the bottom of saddle 1, then by horizontal liquid
Cylinder pressure 17 adjusts the position of slide unit 2, and the position of base 3 is adjusted by advancing jack 10 and carried bottom jack 11, finally by
The position of balance jack 8 and the adjustment back timber 7 of hydraulic vertical prop 9 reaches working face.
Each colliery all suffers from the dismounting work of working surface hydraulic support, how to accomplish not only material-saving but also can safely,
Quick working surface hydraulic support of removing is the current problem for generally facing, and especially geologic structure complexity, roof pressure are big
And broken mine is even more and will remove the roof control of working face as the emphasis in major tasks, design of the present utility model with
Using the roof control problem for solving dismounting work facial triagnle, with utilization and promotional value well.
