Abstract
The invention discloses a pin dismounting device. The pin dismounting device comprises a hydraulic rod, a hydraulic nut, a gasket, a cushion cover and a changing head, wherein the hydraulic nut is firstly mounted at one end of the hydraulic rod, subsequently the gasket is mounted on the hydraulic rod, and lastly the cushion cover and the changing head are mounted on the hydraulic rod. The pin dismounting device disclosed by the invention has the advantages of being simple in structure, convenient in operation for dismounting a pin and capable of saving time, saving labor and protecting equipment.
Description
Technical field
The present invention relates to a kind of out of stock device, particularly relate to a kind of out of stock device.
Background technology
In the various kinds of equipment of colliery, pin need to be dismantled frequently, owing to bearing pin adopts various pins in interference fit, particularly coal machine to use the time long, is more difficult to lay down, makes troubles to maintenance during dismounting, and equipment is easily caused damage by brute-force dismounting.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, easy to operate, time saving and energy saving and protection equipment out of stock device.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of out of stock device, including: hydraulic stem, hydraulic nut, pad, cushion cover and change head, it is characterized in that: hydraulic nut is first arranged on hydraulic stem one end, then installs pad on hydraulic stem, then installs cushion cover successively on hydraulic stem and become head
When the invention have the advantage that use; only the dismounting eye and out of stock device that are disassembled bearing pin need to be become head to connect; hydraulic nut end uses hydraulic stem pressurization, pin can be taken out of, and this apparatus structure is simple and release pin child-operation is convenient, time saving and energy saving and protection equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In accompanying drawing
1, head is become；2, cushion cover；3, pad；4, hydraulic nut；5, hydraulic stem.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described with specific embodiment:
A kind of out of stock device, including: hydraulic stem 5, hydraulic nut 4, pad 3, cushion cover 2 and change 1, hydraulic nut 4 is first arranged on hydraulic stem 5 one end, then installs pad 3 on hydraulic stem 5, then installs cushion cover 2 and change 1 successively on hydraulic stem 5.
When the method have the benefit that use; only the change 1 of the dismounting eye and out of stock device that are disassembled bearing pin need to be connected; hydraulic nut 4 end uses hydraulic stem 5 to pressurize, and pin can be taken out of, and this apparatus structure is simple and release pin child-operation is convenient, time saving and energy saving and protection equipment.
Embodiment described above is only that the preferred embodiment of the present invention is described; not design and the protection domain of the present invention is defined; under the premise without departing from design concept of the present invention; various modification that in this area, technical scheme is made by ordinary skill technical staff and improvement, all should fall into protection scope of the present invention.
