Description
Technical Field
The utility model relates to a mine car buffer is instrument technical field for the dismouting, especially relates to an instrument that is used for dismouting spring apparatus.
Background
In the fields of coal mining, tunneling and other engineering, a mine car is generally used for rail transportation, and the mine car is free of a braking system, so that a mine car buffer is adopted at the joint of the mine car and the mine car to realize rigid collision connection. After the mine car is frequently used, the spring of the buffer of the mine car is seriously fatigued, and is easy to break; when the spring of the buffer of the mine car is replaced, the spring is difficult to detach and assemble due to the characteristics of large diameter, strong elasticity and the like; the intensity of labour of operating personnel is big, simultaneously because spring elasticity is strong, in the installation, if the operating personnel is injured by the easy pop-up of misoperation, danger coefficient is high, consequently, needs to provide a instrument that can assemble mine car buffer spring.
Disclosure of Invention
The utility model provides a tool for disassembling and assembling spring instruments, which solves the problem of difficult replacement of buffer springs of mine cars in the prior art.
In order to realize the purpose, the technical scheme of the utility model is that:
a tool for disassembling and assembling spring instruments comprises a supporting plate and a lead screw, wherein fixing plates are connected to two ends of the supporting plate, a hole is formed in the middle of the supporting plate, a nut is rotatably connected in the hole, the lead screw is arranged in the nut, and the lead screw is in threaded connection with the nut; one end of the screw rod is fixed with a trapezoidal buckle, and the other end of the screw rod is fixed with a bracket; through holes are formed in the two ends of the support.
Further, the support is of a U-shaped structure.
Furthermore, the upper part of the through hole is rectangular, and the lower part of the through hole is of a circular structure.
Further, the supporting plate and the fixing plate are made of I-shaped steel.
Through the technical scheme, the beneficial effects of the utility model are that:
the utility model discloses a setting of backup pad, lead screw and support is worn the through-hole of support on the pin of mine car, and the fixed plate both ends are placed on the mine car buffer, and swivel nut compresses tightly the fixed plate, makes the buffer that the fixed plate was forced to compress the mine car move inwards to realize the installation and the dismantlement of spring, simple structure, convenient to use reduces operating personnel's intensity of labour, guarantees the safety when operating personnel dismantles and installs the spring.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 to 3, a tool for disassembling and assembling a spring instrument comprises a support plate 1 and a lead screw 6, wherein the support plate 1 is made of 11-type i-steel for mining in the embodiment, and the length of the support plate 1 in the embodiment is 600 mm; the two ends of the supporting plate 1 are both connected with fixing plates 2, and the fixing plates 2 are made of I-shaped steel and are conveniently arranged on a buffer of the mine car; a hole is formed in the middle of the supporting plate 1, a nut 5 is rotatably connected in the hole, the screw rod 6 is arranged in the nut 5, and the screw rod 6 is in threaded connection with the nut 5; in the embodiment, the screw rod 6 is made of carbon steel phi 40 with the length of 500 mm; the lower part of the screw rod 6 is fixed with a trapezoidal buckle 7, and the upper part of the screw rod 6 is fixed with a bracket 3; support 3 is "U" type structure, and support 3 adopts long 100mm, thickness to be 80 mm's steel sheet and makes in this embodiment, and through-hole 4 has all been seted up at 3 upper portion both ends of support, 4 upper portions of through-hole are the rectangle structure, and 4 lower parts of through-hole are circular.
When the spring needs to be disassembled, the through hole 4 of the support 3 penetrates through a pin of a mine car, two ends of the fixing plate 2 are placed on a buffer of the mine car, and the fixing plate 2 is tightly pressed by the rotary nut 5, so that the fixing plate 2 is forced to compress the buffer of the mine car and moves inwards for 20-30 mm, and then the pin for fixing the spring is loosened and taken out; and then the nut 5 is loosened reversely, and the buffer and the spring of the mine car can be taken out.
When the spring needs to be installed, after the spring and the buffer are assembled, the support 3 of the lead screw 6 penetrates through the pin of the mine car, two ends of the fixing plate 2 are placed on the buffer of the mine car, the nut 5 is rotated to compress the steel plate at the moment, and the fixing plate 2 is forced to compress the buffer and then moves 20-30 mm inwards to fix the pin. The labor intensity of operators is reduced, and meanwhile, the safety of the operators is improved.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
