Title:

RAISING/LOWERING AND POSITIONING MECHANISM FOR REACTION CROSS BEAM

Document Type and Number:

WIPO Patent Application WO/2022/160854

Kind Code:

A1

Abstract:

A raising/lowering and positioning mechanism for a reaction cross beam, comprising stand columns, and a reaction cross beam which can move up and down along the stand columns and is positioned. Holding mechanisms are provided at the two ends of the reaction cross beam, respectively, and a driving mechanism used for driving the reaction cross beam to ascend or descend is provided on the outer sides of the stand columns; the driving mechanism comprises suspension oil cylinders provided on the outer sides of the stand columns and a double-cylinder synchronous motor hydraulic station provided on the reaction cross beam, and the double-cylinder synchronous motor hydraulic station is communicated with the suspension oil cylinders in an oil path by means of an oil pipe; and the suspension oil cylinders are vertically arranged, cylinder blocks of the suspension oil cylinders pass through and are fixedly connected to the reaction cross beam, and the upper ends of piston rods of the suspension oil cylinders are connected to suspension supports on the outer side surfaces of the stand columns. This mechanism is simple in structure, is safe and reliable, is convenient to disassemble and assemble, can provide great assistance for a vehicle or bogie test, can safely and effectively shorten the mounting time, strives for more test time for a test of a test piece, and significantly improves the test efficiency.
