Device for holding and lifting the reaction beam of the test bench

Abstract

The invention discloses a device for holding and lifting a test bench reaction force beam, which comprises two columns (3) arranged at intervals and a reaction force beam (2) capable of moving up and down along the outer surface of the column (3) and positioned ), the two ends of the reaction force beam (2) are respectively provided with a holding mechanism (5) for fixing the reaction force beam (2) on the column (3), and the column (3) and the A drive mechanism (6) for driving the counter force beam (2) to rise or fall is provided between the counter force beams (2), and the side of the counter force beam (2) attached to the column (3) There are slot-shaped cutouts (13) for assembling the drive mechanism (6). The device has a simple structure, is safe and reliable, and is easy to disassemble and assemble. It can provide a great auxiliary effect for the vehicle or bogie test, can safely and effectively shorten the installation time, gain more test time for the test piece test, and significantly improve the test performance. efficiency.

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...

AI Technical Summary

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
