Description
Technical field
For dismantling the tool for connecting pin shaft in stroke hole when the utility model relates to adjust rod-pumped well stroke.
Background technique
There are two symmetrical cranks on pumping unit horsehead, there are several strokes of mirror image each other on two cranks
Hole is connected with pin shaft in each stroke hole, when adjusting rod-pumped well stroke, needs to disassemble the connection pin shaft.
In general, tool used in dismantling connection pin shaft is sledgehammer, before disassembly, the nut that pin shaft front end connects is screwed down,
So that pin shaft head is exposed to crank surface, then vertically hammers pin shaft head using sledgehammer, pin shaft is finally made to exit stroke hole.
The cooperation of usual pin shaft and stroke hole neck bush is close, in addition pumping unit works long hours, also has and gets rusty sometimes
Phenomenon causes the operation for dismantling pin shaft using sledgehammer highly difficult；In addition, operator is slightly when using sledgehammer hammering pin shaft head
There is the screw thread that will be pounded accidentally to pin shaft surface, causes pin shaft heap button, and the pin shaft of screw thread damage cannot be used continuously, under disassembly
Breakage rate is high for the pin shaft come.
For problem brought by sledgehammer tool ejector pin shaft is used alone, currently, scene is carried out there are also a kind of with sledgehammer
Matching used pin shaft loosening device.The structure of the pin shaft loosening device is that one end has hammering end face, and the other end has helicitic texture.
When dismantling pin shaft, the nut that pin shaft front end connects is screwed down, then connects the pin shaft loosening device by helicitic texture
To pin shaft front end, then apply impact force to the hammering end face of pin shaft loosening device with sledgehammer.
Because having several stroke holes of mirror image each other on pumping unit on two cranks, it is desirable that connected in each stroke hole
Helicitic texture on pin shaft is opposite with the helicitic texture of pin shaft connected in image side stroke hole, that is to say, that side pin shaft
If right-handed thread, then the screw thread of the pin shaft of image side requires to be left-hand thread screw thread.
In this case, it is desirable that there are two pin shaft loosening device must have, one is right-handed thread, another is left-hand thread spiral shell
Line could complete the disassembly of the pin shaft on a pumping unit.For this purpose, needing to take two pin shaft loosening devices when work, on the one hand
Pin shaft loosening device is heavy, not Portable belt, on the other hand, after damage it is complete re-work it is costly.
