Tubing unit box and hood opening-closing mechanism test bed

Abstract

The invention relates to a tubing unit box and a hood opening-closing mechanism test bed. The hood opening-closing mechanism test bed comprises a control device and a mechanical device. The mechanical device comprises an assembly workbench and a pneumatic clamping device. The assembly workbench comprises a workbench body, a simulation vehicle-mounted tubing unit box is installed in the workbench body, and the pneumatic clamping device of full-automatic clamping type is arranged on the upper surface of the workbench body. The control device controls the motion of a hood opening-closing cylinder, a lock opening-closing of a hood opening-closing mechanism and a clamp opening-closing cylinder of the pneumatic clamping device through a magnetic valve and a sensor. The hood opening-closing mechanism test bed is capable of performing comprehensive performance tests for the tubing unit box and the hood opening-closing mechanism and also capable of performing independent tests for the tubing unit box and the hood opening-closing mechanism respectively. The hood opening-closing mechanism test is reasonable in structure, reliable in performance, convenient in mounting and demounting sample parts, low in labor intensity, strong in universality, suitable for performing tests for the tubing unit box and the hood opening-closing mechanism of various bullet train overhaul bases and manufacturers during overhaul and production processes.

Description

technical field [0001] The invention relates to a railway vehicle test device, in particular to a test bench for performing performance tests on piping unit boxes and head cover opening and closing mechanisms for various types of EMUs. Background technique [0002] At present, there are four types of high-speed EMUs operating in my country: CRH1, CRH2, CRH3 and CRH5. The technical parameters of the piping unit box and the hood opening and closing mechanism of each model are different. When performing maintenance, different maintenance bases need to be set up. The piping unit box and the hood opening and closing mechanism of different models are overhauled, and the piping unit box and the hood opening and closing mechanism can only be tested separately, and the comprehensive performance test cannot be tested at the same time. The maintenance efficiency is low and the production cost is high. At present, there is no test equipment capable of performing the performance test of t...

[0002] At present, there are four types of high-speed EMUs operating in my country: CRH1, CRH2, CRH3 and CRH5. The technical parameters of the piping unit box and the hood opening and closing mechanism of each model are different. When performing maintenance, different maintenance bases need to be set up. Overhaul the piping unit box and hood opening and closing mechanism of different models, and the piping unit box and hood opening and closing mechanism can only be tested separately, and cannot be tested comprehensively at the same time, the maintenance efficiency is low, and the production cost is high

At present, there is no test equipment capable of performing the performance test of the piping unit box and the hood opening and closing mechanism at the same time, which is compatible with the performance tests of the piping unit box and the hood opening and closing mechanism of various CRH models, so as to meet the requirements of various CRH EMUs Maintenance test requirements
