Embodiment

[0043] Such as figure 1 , 2 As shown, a rail transit suspension spring disassembly device includes a bracket 1 and a gasket 13. The bracket 1 includes a supporting body 11 and a contact plate 14 connected to each other. The lower surfaces of the supporting body 11 and the contact plate 14 are connected to the jack 4 Connected, the upper surface of the contact plate 14 is connected with the axle box, the gasket 13 is connected with the upper surface of the support 11 and the elastic node 2 respectively, the rising and falling of the jack 4 drives the rising and falling of the bracket 1 and the gasket 13, combined with the elastic force of the spring 3. The elastic node 2 is further raised and lowered to realize the disassembly and assembly of the spring 3.

[0044] The supporting body 11 is a U-shaped body, the opening of the U-shaped body faces upward, and the contact plate 14 is connected to one side of the U-shaped body.

[0045] The contact plate 14 is arc-shaped where it connec...

Abstract

The invention relates to a rail transit suspension spring dismounting device which comprises a bracket (1) and a gasket (13), wherein the bracket (1) comprises a supporting body (11) and a contact plate (14) which are connected with each other, the lower surface of the supporting body (11) and the lower surface of the contact plate (14) are both connected with a jack (4), and the upper surface ofthe contact plate (14) is connected with an axle box. The gasket (13) is respectively connected with the upper surface of the supporting body (11) and an elastic node (2), the ascending and descendingof the jack (4) drive the ascending and descending of the bracket (1) and the gasket (13), and the elastic node (2) is further enabled to ascend and descend by combining the elastic force of a spring(3), so that the dismounting of the spring (3) is realized. Compared with the prior art, the problem of dismounting of the spring of a primary suspension device is solved; the spring dismounting process is safer; the dismounting efficiency of the rail transit suspension spring is improved; and the mass and size are small, and carrying and storage are convenient.

Description

Technical field [0001] The invention relates to the field of rail transit, and in particular to a device and method for disassembling and assembling a rail transit suspension spring. Background technique [0002] The first series of elastic nodes is a device connecting the bogie and the wheel set, one end of which is hinged with the axle box, and the other end is connected with the damping spring. Before removing the damping spring, it is necessary to remove the screw connecting the elastic node and the damping spring, but the damping spring has a pre-tightening torque. If the screw is directly removed without protective measures, it will pop up and hurt people. [0003] The Chinese invention patent CN201821145714.1 specification discloses a flexible node installation auxiliary device, including a clamping plate, a measuring ruler, a worm gear and a moving plate. The upper end of the clamping plate is provided with a first clamping slot penetrating its thickness, and the lower end ...
