The pin shaft dismounting device has the advantages that the pin shafts are pulled out of structural members of the hydraulic support through cooperation of the hydraulic oil cylinder and the lead screw, the pin shaft dismounting device can adapt to different support heights and positions through the lifting oil cylinder and the universal wheels on the base, it is guaranteed that the pin shafts are smoothly pulled out after being aligned with the dismounting device, and the labor intensity of workers in dismounting the pin shafts is greatly relieved.

Description

Coal mine hydraulic supporting eliminator
Technical field
This patent relates to a kind of coal mine hydraulic supporting eliminator, belongs to mining equiment, for the dismounting of bearing pin.
Background technology
Coal mine hydraulic supporting volume is general all very large, and must carry out disintegration before entering well and disassemble, generally support disassemblying is become three parts such as base, back timber, tail boom, then entrucking is gone into the well respectively.Disassemble support and mainly tear hinging pin shaft open, artificial unloading usually adopts and gets rid of pull pin method and chain block of hammer and to pull pin method, but due to bearing pin length and diameter excessive, dismantle very difficult, affect removal efficiency.
Summary of the invention
The object of this invention is to provide a kind of coal mine hydraulic supporting eliminator, solve the problem that artificial unloading's efficiency is low, labour intensity is large.
For achieving the above object, the technical solution used in the present invention is:
A kind of coal mine hydraulic supporting eliminator, comprise lifting support, it is characterized in that, also comprise rotating seat, oil cylinder with pin, screw mandrel, hoist cylinder, with the base of universal wheel, lifting oil pump, to pull pin oil pump, described lifting support is fixed in the middle part of base, hoist cylinder is positioned at lifting support inside, described rotating seat is arranged on hoist cylinder top, described oil cylinder with pin by pinned connection in rotating seat, described screw mandrel runs through oil cylinder with pin inside, screw mandrel one end is provided with nut and is stuck in oil cylinder with pin rear end, the screw mandrel other end coordinates with bearing pin internal thread hole and is connected, described hoist cylinder is connected with lifting oil pump pipeline, oil cylinder with pin is connected with oil pump pipeline of pulling pin.
As preferably, described rotating seat can around the 5 degree of rotations to the left and right of hoist cylinder week, and oil cylinder with pin can around the upper and lower 5 degree of rotations of bearing pin.
As preferably, described lifting oil pump and, oil pump of pulling pin divides and is located at base lifting support both sides.
As preferably, described base and lifting support adopt square tubes soldering.
The invention has the advantages that, utilize the larger pulling force of hydraulic pressure to be pulled down from equipment by bearing pin.Coordinate by hydraulic jack and screw mandrel and bearing pin is extracted out from hydraulic support structural member, this eliminator can be adapted to different support heights and position by the universal wheel on hoist cylinder and base, ensure that bearing pin and provision for disengagement align rear smooth extraction, base is furnished with universal wheel and can moves to any direction, alleviates the labour intensity of workman when tearing pin open greatly.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
In accompanying drawing: 1, nut; 2, oil cylinder with pin; 3, leading screw; 4, rotating seat; 5, bearing pin; 6, lifting support; 7, hoist cylinder; 8, base; 9, universal wheel; 10, lifting oil pump; 11, to pull pin oil pump.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1, comprise lifting support 6, it is characterized in that, also comprise rotating seat 4, oil cylinder with pin 2, screw mandrel 3, hoist cylinder 7, with the base 8 of universal wheel 9, lifting oil pump 10, to pull pin oil pump 11, described lifting support 6 is fixed in the middle part of base 8, it is inner that hoist cylinder 7 is positioned at lifting support 6, described rotating seat 4 is arranged on hoist cylinder 7 top, described oil cylinder with pin 2 is connected to rotating seat 4 by bearing pin 5, it is inner that described screw mandrel 3 runs through oil cylinder with pin 2, screw mandrel 3 one end is provided with nut 1 and is stuck in oil cylinder with pin 2 front end, screw mandrel 3 other end with to dismantle bearing pin internal thread hole and coordinate and be connected, described hoist cylinder 7 is connected with lifting oil pump 10 pipeline, oil cylinder with pin 2 is connected with oil pump 11 pipeline of pulling pin.
According to described coal mine hydraulic supporting eliminator, described rotating seat 4 can around hoist cylinder 5 degree of rotations to the left and right in 7 weeks, and oil cylinder with pin 2 can around the upper and lower 5 degree of rotations of bearing pin.
According to described coal mine hydraulic supporting eliminator, described lifting oil pump 10 and 11 points, oil pump of pulling pin are located at base 8 lifting support 6 both sides.
According to described coal mine hydraulic supporting eliminator, described base 8 adopts square tubes soldering with lifting support 6.
The base of this device adopts structure of steel product welding arrange and ensure certain structural strength and weight.
When tearing pin open, pin oil cylinder 2 front end is torn in adjustment open and required bearing pin outer end is in same direction, first start lifting oil pump, oil cylinder with pin 2 and bearing pin to be torn open are aligned, then by screw mandrel 3 and bearing pin, tear pin oil cylinder 2 open and couple together, pin oil pump is torn in operation open, utilizes hydraulic coupling hydraulic control oil cylinder constantly to stretch out, and drives screw mandrel to be pulled out by bearing pin.Oil cylinder with pin can realize up and down along connecting rod, the rotation of 45 degree, left and right.After extracting, bearing pin falls by operation lifting oil pump, by universal wheel mobile chassis, just bearing pin can be moved to other place.
