Integral lifting steel wire rope device and bogie and vehicle body of integral lifting steel wire rope device

Abstract

The invention provides an integral lifting steel wire rope device. The integral lifting steel wire rope device comprises a steel wire rope body and steel wire rope lantern rings, wherein the steel wire rope lantern rings are arranged at the two ends of the steel wire rope body, and the steel wire rope lantern rings at the two ends are connected with a frame lifting base of a bogie and a lifting base of a vehicle body respectively. The integral lifting steel wire rope device is not limited by a dragging handle or an adjusting gasket in the prior art any more, and under the condition that the stress of a steel wire rope is within a bearable range when a bogie is integrally lifted, the steel wire rope lantern rings at the two ends are freely fixed to the frame lifting base of the bogie and the lifting base of the vehicle body through connection pins respectively, so that the steel wire rope device is allowed to be dislocated to a certain extent at the vertical installation position of thevehicle body end and the vertical installation position of the bogie end. According to the integral lifting steel wire rope device, the frame lifting base installed on the bogie can be flexibly installed above a frame transverse beam or on the lateral side of the frame transverse beam or at other suitable positions of a frame, and the integral lifting steel wire rope device can be suitable for the compact design space between the bogie and the vehicle body.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle bogies, and in particular relates to an integral hoisting wire rope device, a bogie and a car body thereof. Background technique [0002] With the increase of passenger capacity and various functional requirements of rail vehicles at home and abroad, especially for new double-decker passenger and freight trains, the space inside the bogie and between the bogie and the car body tends to be compact, how to use the compact space Meeting various requirements is an urgent problem to be solved for the new bogie. [0003] An example of the installation structure of the existing integral hoisting wire rope device on the bogie frame is as follows: figure 1 As shown, the wire rope is composed of a drag handle 3, a wire rope body 4 and a collar 5. The lower end of the drag handle 3 is installed on the frame mounting seat 1 through a fastener and an adjusting gasket 2, and the upper end is installed thr...

Problems solved by technology

[0005] In addition, the device also includes the following limitations: there needs to be space on the side of the frame beam steel pipe for arranging the frame hoisting seat, that is, the steel wire rope cannot be installed directly above the beam steel pipe; other equipment under the frame hoisting seat should be prevented from interfering with the wire rope drag handle; The steel wire rope body is prone to wear and tear when passing through the lifting seat of the frame, and a protective cover needs to be installed, and the structure tends to be complicated; when the wire rope device is installed and as the wheel wears out, it is necessary to increase or decrease the adjustment gasket to adjust the position of the wire rope.
