Embodiment Construction

[0014] The hydraulic test system of railway tamping device load motor of the present invention can be applied to such as figure 1 In the hydraulic test system of the entire railway tamping device shown, the hydraulic test system of the load motor includes an oil tank 1 and a load motor test circuit. The load motor test circuit mainly includes a shock absorber 11, a first oil suction pump 12, and a logic valve. 13. The input end of the shock absorber 11 is connected to the fuel tank 1, and the output end is connected to the first oil suction pump 12; The output end of the logic valve 13 is respectively connected with the load motor group 2 of the tamping device through the pipe check valve; the input end of the logic valve 13 is respectively connected with the output end of the load motor group 2, and the output end of the logic valve 13 is connected through the first oil return filter. To the oil tank 1, and the logic valve 13 is electrically connected, and the power is cut of...

Abstract

The invention discloses a hydraulic test system of a loading motor of a railway tamping device. The hydraulic test system of the loading motor of the railway tamping device comprises an oil tank and a loading motor test loop. A simulation test can be carried out on the loading motor through the loading motor test loop, the quality of the loading motor is tested, and the loading motor can be maintained conveniently. Oil inside the oil tank can be cooled through an oil tank cooling loop. Due to the arrangement of a logical valve, when a motor of a first oil suction pump stops, power is lost for stopping, then a loading motor set stops rotating, and the motor is prevented from continuously rotating and causing air suction. Due to the arrangement of a pilot-operated type overflow valve, pressure in the loading motor test loop can be limited.

Description

technical field [0001] The invention belongs to a hydraulic power station, in particular to a hydraulic test system for a load motor of a railway tamping device. Background technique [0002] At present, railway tamping devices are common railway maintenance equipment. During its use, it is often necessary to overhaul its load motor group. After the overhaul, it also needs to be loaded and tested. If any problem is found, it needs to be dismantled and overhauled again, which is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic test system for a load motor of a railway tamping device, which can carry out a simulation test on the load motor, test its quality, and facilitate its maintenance. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A hydraulic test system for a load motor of a r...
