Hydraulic support is the conventional supporting facility in colliery, as hydraulic support is increasing, between each structure member
Connection bearing pin is also increasing, and by original φ 80*400 increases, φ 150*750, bearing pin are assembled from bearing pin size till now
So trouble, 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 caused impulsive force is limited, Zhi Nengshi to percussion hammer on the guide bar
For the extraction of small clevis pin with head, the extraction to big bearing pin is with regard to 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 is big, underground needs to take apart on large hydraulic support when installing, reclaiming
Into part, with convenience in 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 recovery simultaneously
During upper well, it is serious in subsurface environment corrosion to be hinged big axle, disassembles very difficult, support organic efficiency is low.
Utility model content
In order to solve the above technical problems, the utility model provides, one kind is easy to operate, and dismounting is efficiently used for hydraulic pressure of the colliery
The hydraulic pin remover of support dismounting.
