Abstract

The invention relates to a novel hydraulic control system for a car dumper. The novel hydraulic control system for the car dumper comprises a hydraulic pump station, a car pressing device and a car leaning device, wherein the hydraulic pump station comprises a hydraulic pump, a driving device, a fuel tank and a hydraulic system; the hydraulic pump station is mounted on the ground; a control device is adopted; the car pressing device and the car leaning device are controlled by the control device; the driving device comprises a motor and the hydraulic pump and is connected with the hydraulic system through a hydraulic fuel path in a matched manner; the fuel tank is connected with the hydraulic system through the hydraulic fuel path in a matched manner; the car pressing device is a car pressing oil cylinder; the car leaning device is a car leaning oil cylinder; and the fuel tank is provided with a fuel level indicator, an air filter, a heater, a cooler and a fuel temperature measuring device. A hydraulic component with a differential circuit is adopted; a shuttle valve is arranged; a control cover plate capable of monitoring the off position with electricity is adopted; and a QM type induction stroke limiter is used for monitoring. The novel hydraulic control system for the car dumper has the advantages of novel idea, reasonable structure, stable performance and safety and reliability in application.

Description

technical field [0001] The invention relates to a hydraulic control system, in particular to a hydraulic control system for a dumper. The dumper is special equipment for dumping railway gondola cars, which belongs to the technical field of bulk material handling mechanical equipment. Background technique [0002] The dumper is a large-scale mechanical equipment used to dump railway open cars. It is suitable for large-scale thermal power plants, chemical plants, cement plants, ports, storage and transportation stations, and coking plants and sintering plants in the metallurgical industry. It is used for dumping various Coal, ore and other bulk materials carried by open railway cars. According to the number of dumping vehicles each time, the dumpers are divided into single-vehicle dumpers, double-vehicle dumpers, and three-vehicle dumpers. [0003] When the dumper starts dumping, it needs to drive its pressing mechanism and leaning plate to carry out pressing and leaning. A...
