Hydraulic Driven Rail Transfer Trolley

The rail transfer trolley is a kind of flatbed trolley running on the track, which is generally composed of electrical control system, walking wheel system, power supply system, drive system and frame. Because of its fast transportation speed and high efficiency, it is widely used in the process of industrial production, goods transfer or large equipment transfer. In the existing hydraulic driven rail transfer trolleys, the rail flat trolley usually drives the rail wheel to rotate through the motor drive reducer, and the speed is adjusted through the motor controller. The operation mode adopts wired control and wireless remote control, and the reverse rotation of the motor is controlled by the contactor to realize the forward and backward of the flat trolley. Therefore, it is necessary to set multiple motor drive reducers and motor controllers, which leads to the increase of production cost. On the other hand, in order to lift the transported goods, the existing rail flatbed carts usually lift the flat plate set on the frame through the folding frame structure set in the frame, so as to realize the lifting of goods. The lifting process is slow. At the same time, there are certain requirements for the weight of transported goods, which reduces the practicability and transportation efficiency of rail flat carts. Therefore, the existing hydraulic driven rail flat trolley has defects and needs to be improved.

The rail transfer trolley of full hydraulic drive type includes: trolley body, power supply, oil pump drive motor, hydraulic drive system set in car body, wheel components set under trolley body; oil pump drive motor is electrically connected with power supply; hydraulic drive system includes: four lifting oil cylinders, hydraulic synchronous motor connected with four lifting oil cylinders, oil tank, hydraulic drive motor, gear pump. The output shaft of the oil pump driving motor is connected with the gear pump, the oil inlet end of the gear pump is connected with the oil tank through the pipeline, the oil outlet end of the gear pump is respectively connected with the hydraulic synchronous motor and the hydraulic driving motor through the pipeline, and the hydraulic driving motor is connected with the wheel assembly. The patent full hydraulic driven rail transfer trolley of the utility model can lift the goods with a load of 100t, with large load, so that the rail transfer trolley is no longer limited by the load, and its practicability is enhanced.
