Side-turn cart and control system thereof

Abstract

The invention provides a side-turn cart and a control system of the side-turn cart. The control system of the side-turn cart comprises hydraulic cylinders, a pneumatic hydraulic pump and pneumatic control reversing valves, wherein each hydraulic cylinder comprises a cylinder body, a piston is arranged in each cylinder body, each piston divides each cylinder body into a first cavity body and a second cavity body, the number of the hydraulic cylinders is four, every two hydraulic cylinders are set as one group, the two groups of the hydraulic cylinders are respectively arranged at two sides of the side-turn cart, the pneumatic hydraulic pump is provided with an air inlet, a liquid inlet and a liquid outlet, the air inlet is communicated with a pressure air source, the liquid inlet is communicated with a pressure liquid source, the pneumatic control reversing valves are connected between the pneumatic hydraulic pump and the hydraulic cylinders, the number of the pneumatic control reversing valves is two, and every two hydraulic cylinders at one side of the side-turn cart are communicated with one pneumatic control reversing valve. The side-turn cart comprises a cart compartment and the control system. According to the side-turn cart and the control system of the side-turn cart, through the arrangement of the hydraulic cylinders, the pneumatic hydraulic pump and the pneumatic control reversing valves, the safe stability of the side-turn cart is improved.

Description

technical field [0001] The invention relates to the drive technology of a rollover vehicle, in particular to a rollover vehicle and its control system. Background technique [0002] At present, there are two main transmission methods for railway rollover vehicles. One is to use the locomotive pressure wind source to drive the cylinder to expand and contract to realize rollover for unloading operations; the other is to use ground power or diesel generators to drive the motor to drive the hydraulic pump. Provide pressure oil source, and then realize rollover and unloading through the expansion and contraction of hydraulic cylinder. [0003] The air compressor equipped with the locomotive engine provides a pressure air source, drives the cylinder to expand and contract, and realizes vehicle rollover and unloading. The buckle phenomenon; the air cylinder is large in volume, and there are rollover vehicles driven by cylinders, the pressure air is usually about 600Kpa, and the di...

AI Technical Summary

Problems solved by technology

[0003] The air compressor equipped with the locomotive engine provides the pressure air source, drives the cylinder to expand and contract, and realizes the rollover and unloading of the vehicle, which can effectively use the air source. The buckle phenomenon; the air cylinder is large in size, and there are rollover vehicles driven by cylinders. The pressure air is usually about 600Kpa, and the diameter of the cylinder reaches about 800mm; the controllability is poor, and the speed of the air cylinder is uncontrollable because it uses pneumatic expansion and contraction. , and then the movement suddenly accelerated

The transmission mode of hydraulic cylinder driven by generator set or ground power supply is usually AC220V or AC380V. Due to the introduction of high-voltage power supply, the safety requirements are higher, and it is not easy to use in anti-riot occasions.
