Problems solved by technology

This method requires the use of tools for related operations, and the transmission efficiency is low. Usually, the operator does not perform the operation of jacking up the counterweight, which will easily lead to a reduction in the service life of the wire rope, thereby affecting the function of the lifting device to lift the upper chassis.

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the drawings and embodiments.

[0022] Such as figure 1 , figure 2 As shown, the present invention provides a jacking device for railway freight cars, which includes a fixed beam 1, a fixed seat 2, a rotating cam, a top block, a limit device and a stopper. Both ends of the fixed beam 1 are connected to the base of the truck by bolts, so that the fixed beam 1 is fixed on the inner wall of the truck; a fixed seat 2 is provided at the middle position of the fixed beam 1. The rotating cam is arranged in the middle of the fixed base 2 through a pin shaft, and the limiting device is also arranged on the outside of the fixed base 2 through the pin shaft. After the limiting device locks the rotating cam, the rotating cam cannot rotate counterclockwise. The top block is arranged in the middle of the fixed beam 1, the upper part of the rotating cam is in close contact with the lower end of the top block, and ...

Abstract

The invention relates to a jacking device for a rail wagon. The jacking device comprises a fixing beam, a fixing base, a rotating cam, a top block, a limiting device and stop iron. The two ends of the fixing beam are connected with a base of a wagon through bolts. The fixing base is arranged in the middle of the fixing beam. The fixing base is of a U-shaped structure. The rotating cam is arranged in the middle of the fixing base through a pin shaft. The limiting device is arranged on the outer side of the fixing base through a pin shaft. The top block is arranged in the middle of the fixing beam. The upper portion of the rotating cam makes tight contact with the lower end of the top block. The upper end of the top block penetrates through the fixing base and the fixing beam to make contact with a balancing weight. The stop iron is fixedly arranged on the fixing beam on one side of the top block. The jacking device is easy to operate and high in efficiency and improves the reliability of a lifting device.

Description

Technical field [0001] The invention relates to a jacking device, in particular to a jacking device for railway freight cars used in the railway field. Background technique [0002] At present, the SQ6 type double-deck railway transport vehicle is equipped with a lifting device, which uses a counterweight to achieve lifting. In order to ensure that the wire rope is not stressed during operation, the method of lifting the counterweight with bolts is required. This method requires the use of tools for related operations, and the transmission efficiency is low. Usually, the operator does not carry out the operation of lifting the counterweight, which easily causes the service life of the wire rope to be reduced, thereby affecting the function of lifting the upper chassis of the lifting device. Summary of the invention [0003] In view of the above problems, the object of the present invention is to provide a jacking device for railway freight cars, which has simple operation and hig...
