A hydraulically driven transfer device

Abstract

The invention discloses a hydraulically powered transfer device and belongs to the field of transport devices. The hydraulically powered transfer device comprises four work branches, the first work branches controls linear motion of a third track, the second work branch controls linear motion of a second track, the third work branch controls rotation of a rotary table, and the fourth work branch controls linear motion of a first track on the rotary table. A hydraulic motor driving technology is adopted, so that low-speed large-torque transmission and frequent reversing are easy to achieve; an energy accumulator serves as an auxiliary power source, has high power density and can recycle braking energy, and thus, energy sources are greatly saved; and the oil return backpressure liquid resistance of an oil return path of a constant displacement motor is set through return oil throttling speed adjusting, the speed can be automatically controlled easily, and operation smoothness is ensured.

Description

technical field [0001] The invention relates to a transport device, in particular to a hydraulically driven transfer device. Background technique [0002] The bogie is one of the key components of a railway passenger car, and its parameter performance directly determines the running speed, safety and comfort of the train, so it is necessary to regularly overhaul the bogie. During the overhaul process, the bogie needs to be transferred between equipment in different stations. In order to improve the transfer efficiency, transfer safety and transfer convenience of the bogie, the advanced repair workshop is equipped with a ground track transfer line, which is roughly divided into straight line transportation and turntable steering. Through on-site investigation, it was found that the transfer line was not practical, mainly due to the low speed of straight-line transportation, insufficient power of the turntable and easy jamming, and the inability to realize automatic flow cont...

AI Technical Summary

Problems solved by technology

Through on-site investigation, it was found that the transfer line is not practical, mainly due to the low speed of straight-line transportation, insufficient power of the turntable and easy jamming, and the inability to realize automatic flow control between lines

The existence of the above problems has led to a very low efficiency of bogie transfer and maintenance, which is far less than that of manual transfer.

In view of this situation, the current transfer of bogies still relies on manual work. In this way, not only the number of personnel is large, but also the work intensity is high and the work efficiency is low.
