It is our problems to be solved.
Utility model content
For various deficiencies of the prior art, now providing one kind can quickly pull pin what the pin shaft of formation abrasion was extracted
Device.
To achieve the above object, the utility model provides the following technical solutions:
A kind of hydraulic support pin removal, including jack of pulling pin, the jack of pulling pin include piston rod and cylinder body, institute
State piston rod be located at cylinder interior one end be equipped with piston head, it further includes bolt that end, which is located at outside cylinder body, the bolt
One end sequentially passes through the piston rod and cylinder body and connect with pin shaft to be dismantled, the other end and the fixed company of the piston-rod end
It connects.
Further, the bolt is fixed with the piston-rod end by nut, the nut and the piston-rod end
Between be equipped with securing plate.
Further, lengthening set is fixed with outside the cylinder body, the lengthening set is located along the same line with the cylinder body, institute
It states and lengthens set described in bolt-through.
Further, the first guide ring and first sealing device are equipped between the piston head and cylinder interior.
Further, the first sealing device includes chevron circle and the first flower bud type circle.
Further, the piston rod is arranged with guide sleeve at cylinder mouth, and the is equipped between the guide sleeve and piston rod
Two guide rings and the second sealing device.
Further, second sealing device includes the second flower bud type circle and O-ring.
The beneficial effects of the utility model are:
1, the inside of the bolt-through piston rod, the pressure that plunger shaft generates can effectively be transferred to bolt, be conducive to
Pin shaft to be dismantled is pulled out.
2, first sealing device includes chevron circle and the first flower bud type circle, and the second sealing device includes the second flower bud type circle and O-shaped
Circle, can effectively play sealing function.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In attached drawing: 1- pin shaft to be dismantled, 2- pull pin, and jack, 3- lengthen set, 4- bolt, 5- securing plate, 6- nut, 7- live
Stopper rod, 8- piston head, 9- guide sleeve.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below with reference to the utility model
Attached drawing carries out clear, complete description to the technical solution of the utility model, and based on the embodiment in the application, this field is general
