Problems solved by technology

[0004] First of all, the crane is used to lift the counter force beam, the work efficiency is low, and there are potential safety hazards
[0005] Secondly, the front and rear clamping plates are used to fix the reaction force beam. The weight of the front and rear clamping plates is relatively large, about 453kg, and cannot be moved manually. There is a gantry frame above the clamping plate to hinder the lifting of the crane, which is not easy to disassemble and assemble the beam.
[0006] Furthermore, the beam cannot be lifted and lowered independently, and can only be lifted by means of a crane, which is inconvenient to use
[0007] Finally, adjusting the installation height of the beam by hoisting the crane is not only time-consuming, labor-intensive, low-precision, but also has potential safety hazards

Abstract

The invention discloses a device for holding and lifting a counter-force beam of a test bed. The device comprises two stand columns (3) arranged at an interval and the counter-force beam (2) capable of moving up and down along the outer side faces of the stand columns (3) and being positioned, wherein holding mechanisms (5) used for fixing the counter-force beam (2) to the stand columns (3) are arranged at the two ends of the counter-force beam (2) respectively, a driving mechanism (6) used for driving the counter-force beam (2) to ascend or descend is arranged between the stand columns (3) and the counter-force beam (2), and a groove-shaped notch (13) used for assembling the driving mechanism (6) is formed in the face, attached to the stand columns (3), of the counter-force beam (2). Thedevice is simple in structure, safe, reliable, convenient to disassemble and assemble and capable of providing a great auxiliary effect for vehicle or bogie tests, the installation time can be safelyand effectively shortened, more test time is bought for tested piece tests, and the test efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle test devices, in particular to a device for lifting, lowering and fixing a test bench reaction beam in the design process of a rail vehicle. Background technique [0002] With the vigorous development of the rail transit industry, the vehicle design technology has been constantly innovating, and the continuous verification of the performance and reliability of the vehicle design has also continued to increase. Therefore, safe and reliable test equipment cannot be ignored. [0003] A typical test bench includes a reaction beam. During the test, the height of the reaction beam needs to be adjusted and fixed, but the existing equipment has the following disadvantages: [0004] First of all, using the crane to lift the counter force beam has low operating efficiency and potential safety hazards. [0005] Secondly, the front and rear clamping plates are used to fix the reaction force beam. The we...
