Abstract
The utility model discloses a kind of pin removal extracted for hydraulic support bearing pin, including stud, anchor cable lock, anchor cable, sleeve and supporting plate, the sleeve bottom is welded with supporting plate, and supporting plate center is machined with anchor cable and stretches out hole, and anchor cable is stretched out in hole from anchor cable to be passed through whole sleeve；The anchor cable front end is additionally provided with anchor cable lock, and anchor cable lock front end is welded with stud.The beneficial effects of the utility model are that making is simple, quick, cost is cheap and service life is grown, and improves operating efficiency using the present apparatus, has saved resource.
Description
Technical field
It the utility model is related to coal mine machinery technical field, more particularly to a kind of pulling pin for the extraction of hydraulic support bearing pin
Device.
Background technology
Colliery is adjusted due to production area in process of production, and working face needs to install and reclaimed, and generally requires hydraulic pressure
Support carries out disassembling assembling, because underworkings gross distortion ceiling height lowest part only has 2 meters, support gross weight permits more than winch
Perhaps the maximum weight lifted, hydraulic support need to disassemble into top cover, tail boom, column and the part of base four in underground transportation.Hydraulic pressure
Support upper pin fit clearance is small, has for a long time in underground using the generation for causing corrosion phenomena in the environment of water and coal dust, stiff
Extremely in pin-and-hole, gas cutting can only be used, has a strong impact on safety；Before can only be with instruments such as crowbars bit by bit by it from support
Sled gets off, and an assembling and dismantling sometimes, which unload personnel one day, can just tear four to five serious pins of deformation open, extremely inefficient；And in order to ensure
Progress, dismounting personnel amount can only be increased, waste a large amount of manpowers.
Utility model content
For disadvantages described above, the utility model provides a kind of pin removal extracted for hydraulic support bearing pin, existing to solve
There is hydraulic support dismounting operating efficiency low, the problem of wasting time and energy.
To achieve the above object, the utility model uses following technical scheme：

Embodiment
The utility model is specifically described below in conjunction with the accompanying drawings, as Figure 1-3, one kind is used for hydraulic support bearing pin
The pin removal of extraction, the sleeve 4 are made using 6 writing brushes, and the top of sleeve 4 is provided with gap 8, and gap 8 can allow sleeve 4 to avoid pin
Axial prominent gusset, allows sleeve 4 smoothly to withstand on working face；In the bottom soldering pallet 5 of sleeve 4, supporting plate 5 is to rise
The acting surface of oil cylinder is drawn, the anchor cable that a diameter of 20mm is processed in the center of supporting plate 5 stretches out hole 7, with a diameter of 17.8mm anchor
Rope 3 stretches out hole 7 through anchor cable and runs through whole sleeve 4；Two anchor cable locks 2 are installed in the front end of anchor cable 3, rear end anchor cable lock 2 is used
In connection tensioner anchor cable 3, front end anchor cable lock 2 do not put lock core by anchor cable 3 put in increase anchor cable 3 by moment, in front end anchor
The front end welding M30 of rope lockset 2 stud 1；The carrying present apparatus for convenience, all it is welded with the side of sleeve 4 and supporting plate 5
Handle 6.
The operation principle of the present apparatus：When using the present apparatus, the stud 1 of the front end of anchor cable 3 is first screwed to the screwed hole of bearing pin
It is interior, then sleeve 4 is withstood on the working face where bearing pin, will rise and draw oil cylinder to withstand on supporting plate 5 anchor cable 3 in succession, finally start
Rise and draw oil cylinder supercharging outwards to pull bearing pin by anchor cable 3.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody principle of the present utility model to some variations that some of which part may be made, and belong to the utility model
Protection domain within.
