Description
Technical field
The present invention relates to hydraulic pressure of the colliery equipment, particularly a kind of hydraulic pin remover dismantled for coal mine hydraulic supporting.
Background technology
Hydraulic support is the conventional supporting facility in colliery, as hydraulic support is increasing, between each structure member
Connect bearing pin also increasing, bearing pin size is by original φ 80*400 increases φ 150*750 till now, and bearing pin is assembled from
It is so troublesome, the problem of dismounting of bearing pin is also one very important.Because original bearing pin is smaller, dismounting is with mechanically pulling pin
Device.Quick mobile generation impulsive force of the mechanical pin removal mainly by percussion hammer on the guide bar, makes bearing pin be extracted from pin-and-hole.And
The quick movement of percussion hammer applies by human hand, it is clear that the impulsive force that percussion hammer is produced on the guide bar is limited, Zhi Nengshi
For the extraction of small clevis pin with head, the extraction to big bearing pin is just helpless, and this mode of pulling pin is easily damaged the end of bearing pin
Face screw.
Because the volume of large hydraulic support is big, weight big, underground needs to take apart on large hydraulic support when installing, reclaiming
Into part, to facilitate transport or go into the well, therefore need pin removal to extract the bearing pin for coupling each part of large hydraulic support, and to pull out
Go out φ 150*750 and the bearing pin being clamped, be clearly not all right using old-fashioned mechanical pin removal.Hydraulic support is reclaimed simultaneously
During upper well, it is serious in subsurface environment corrosion to be hinged big axle, disassembles very difficult, and support organic efficiency is low.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of easy to operate, dismounting is efficiently used for coal mine hydraulic supporting
The hydraulic pin remover of dismounting.
The present invention solve its technical problem use technical scheme be：
A kind of hydraulic pin remover dismantled for coal mine hydraulic supporting, including oil cylinder, are supported outside overcoat, connector, the support
The through-hole structure of longitudinally through body is arranged with, the outer end of support overcoat is more than the outer toroid of support overcoat external diameter provided with external diameter,
The inner of support overcoat is provided with inner affixed, the oil of the inner affixed interior annular with supporting overcoat, interior annular and cylinder block
The piston rod of cylinder is placed in the through hole of support overcoat；The outer end of cylinder piston rod is hinged by one end of bearing pin and connector, even
The shoulder hole structure of insertion body of the joint provided with longitudinal direction, one end of bearing pin connector is placed in the shoulder hole of connector.
Using the present invention of above-mentioned technical proposal, compared with prior art, beneficial effect is：
Simple in construction, easy to operate, dismounting is quick, is effectively protected the end face screw of bearing pin, time saving and energy saving.
Further, prioritization scheme of the invention is：
The section of the support overcoat through hole is ellipse or circular.
The outer face of the outer toroid is provided with reticulate structure.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
A kind of hydraulic pin remover dismantled for coal mine hydraulic supporting, including oil cylinder 1（Shown in Fig. 1）, support the interior of overcoat 2
End is provided with interior annular 2-3, and interior annular 2-3 is welded to connect with support overcoat 2, and interior annular 2-3 inner face is with cylinder block 1-3's
Outer face is bolted.Overcoat 2 is supported to be provided with the through-hole structure 2-1 of longitudinally through body（Shown in Fig. 2）, support overcoat to lead to
Hole 2-1 section is ellipse or circular, and the outer end of support overcoat 2 is provided with outer toroid 2-2, and outer toroid 2-2 is welded with support overcoat 2
Connect in succession, outer toroid 2-2 outer face is provided with reticulate structure（Shown in Fig. 3）, its effect is the outer toroid when the present embodiment is pulled pin
2-2 is close to hydraulic support side plate in the presence of pretightning force, it is not skidded.It is outer that the piston rod 1-4 of oil cylinder 1 is placed in support
In the through hole 2-1 of set 2, cylinder piston rod 1-4 outer end is hinged by one end of bearing pin 3 and connector 4, and connector 4 is provided with vertical
To insertion body shoulder hole structure 4-1, one end of bearing pin connector 5 is placed in the shoulder hole 4-1 of connector 4.This example
Middle bearing pin connector 5 is bolt, and the nut portion of bearing pin connector 5 is placed in shoulder hole 4-1.Connector 4 is provided with plurality of specifications, leads to
The connector 4 for changing different size is crossed, the bearing pin of various screw thread specifications can be pulled out, with versatility.Connector 4 and axle to be pulled pin
6 are bolted, because hydraulic coupling is the characteristics of gradually increase, it is to avoid the end face screw of axle 6 to be pulled pin is damaged.Oil cylinder 1
Cylinder body 1-3 welding hanging ring 1-5, lift and use.The present embodiment also include hydraulic power unit and hydraulicdirectional control valve, hydraulic power unit and
