Tool for dismounting central traction apparatus of bogie

Abstract

A tool for dismounting a central traction apparatus of a bogie is characterized by comprising a transition supporting seat, a supporting pin, a hydraulic cylinder and a cylinder jacket, wherein a central hole is formed in the transition supporting seat; the supporting pin is mounted in the central hole; the lower part of the transition supporting seat is connected with the cylinder jacket; the hydraulic cylinder is arranged in the cylinder jacket; a piston in the hydraulic cylinder is placed below the supporting pin; an oil injection hole is formed in a side wall of the hydraulic cylinder and is connected with an oil line pipe; and outer threads are arranged on the outer wall of the upper part of the transition supporting seat and are connected with an inner thread mounting connector of a conical rubber steel sleeve in a matched manner. According to the scheme, in an assembling process of the tool, the tool only needs to be assembled according to an existing connector, and specific requirements on fit dimensions do not exist. In an implementing process, only an operator needs to apply pressure to the cylinder through a hydraulic system, then a large dismounting force can be applied, and requirements on skill of the operator are low. Through an oil line of the hydraulic system, the operator can be away from a part, which is combined to the bogie, of a vehicle body when operating an oil pump, dangers are avoided, and space limitation does not exist.

Description

technical field [0001] The invention relates to a dismantling tool for a rail transit vehicle, in particular to a hydraulic dismantling tool for a central traction device of a bogie. Background technique [0002] With the development of urban rail transit, there are more and more connection methods between the car body and the bogie in rail transit vehicles through conical fit. At present, most of the dismantling tooling used for conical fit adopts mechanical structure. The operator applies force to a large hexagon head bolt through an extended torque wrench, and the axial force of the hexagon head bolt makes the car body and the bogie Achieve separation. There are the following problems in this disassembly method: [0003] 1. The operation process is relatively complicated, and a special tool for an extended torque wrench is required; [0004] 2. Due to the use of the extended torque wrench, it must be continuously fixed on the hexagonal head bolt by the operator during ...

AI Technical Summary

Problems solved by technology

[0003] 1. The operation process is relatively complicated, and a special tool for an extended torque wrench is required;

[0004] 2. Due to the use of the extended torque wrench, it must be continuously fixed on the hexagonal head bolt by the operator during the implementation process. Moreover, due to the large disassembly force required, at least two operators must use the extended torque wrench at the same time. Hex head bolts exert force and require high skill for operators;

[0005] 3. Since an operator continues to fix the extended torque wrench to the hexagon head bolt, which is directly below the separation position, the safety and reliability are low;

[0006] 4. Since the separation position is directly below the center of the bogie, the operation space of the extended torque wrench is small and inconvenient to operate
