Full-hydraulic split type cableway traction machine

Abstract

The invention relates to a full-hydraulic split type cableway traction machine. The full-hydraulic split type cableway traction machine comprises a power system, a hydraulic system and a traction system, wherein the power system, the hydraulic system and the traction system are arranged independently. The full-hydraulic split type cableway traction machine is characterized in that the power system comprises an engine and a hydraulic motor, the hydraulic system comprises a hydraulic variable pump which is driven by the engine, the hydraulic variable pump is used for driving the hydraulic motor, a high-pressure overflow valve is arranged between the hydraulic motor and the hydraulic variable pump, and the traction system comprises a traction drum which is driven by the hydraulic motor through a speed reducer. The full-hydraulic split type cableway traction machine further comprises a control system which is arranged independently, wherein the control system comprises a pressure control valve and a directional control valve, the pressure control valve is used for controlling the power system, the hydraulic system and the traction system, and a pressure gauge is arranged on the high-pressure overflow valve. According to the full-hydraulic split type cableway traction machine, stepless speed change is achieved, transmission is easy, hydraulic brake is reliable, and operation is easy; in addition, the continuous traction force is large, the traction speed is high, and the traction requirement of heavy-load cableways is met.

Description

technical field [0001] The invention relates to a fully hydraulic split cableway tractor, which is applied to cableway transportation. Background technique [0002] The performance of the cableway tractor directly determines the transportation efficiency of the temporary overhead freight ropeway. The existing cableway tractor is generally refitted from a motorized winch, and the price is relatively low, but the traction power is not large, the braking performance is not good, and the operation time is low. High heat, low speed, high failure rate. The existing hydraulic cableway traction machine has an integrated structure, belt drive, single-drum traction, general braking, and the maximum traction force is only 1.5t, which cannot meet the traction requirements of heavy-duty cableways. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a fully hydraulic split cableway traction machine. [0004...
