Abstract

The invention provides a driving device for a small rail car. The driving device is a hydraulic driving device. The hydraulic driving device consists of a motor pump group, an oil cylinder, a controlvalve group and an auxiliary device. The driving device adopts a gear pump with a simple structure and a low price. The gear pump also has the advantages of small size, light weight, good self-absorbing performance, convenient maintenance and repair and the like. The outlet of the pump is equipped with an electromagnetic relief valve for controlling the pressure of the system, the electromagneticrelief valve can realize zero-load start of the motor, the normal operation of a feeding device is realized, the production efficiency is improved, and the problem that the previous feeding device isoften stuck on the rail as a result of asynchrony of two cylinders can be changed.

Description

technical field [0001] The invention relates to the technical field of moving trolleys, in particular to a driving device for rail trolleys. Background technique [0002] In the prior art, the structure of the driving device of the feeding trolley is complex, and the feeding device cannot be accurately controlled for feeding, and the phenomenon that the feeding device is easily stuck on the track during the feeding process occurs, and the production efficiency is low. Contents of the invention [0003] In order to overcome the following problems in the prior art, the feeding trolley cannot accurately control the feeding device for feeding, and it is easy to cause the feeding device to be stuck on the track during the feeding process, resulting in low production efficiency. The present invention provides a driving device for rail trolley, which is characterized in that: the driving device is a hydraulic driving device, and the hydraulic driving device includes a motor pump ...
