PC program control soft starting and falling device

A PC program control soft starting and falling device belongs to the technical field of control of scissor automobile elevators, and comprises a main oil cylinder I, an auxiliary oil cylinder I, a main oil cylinder II, an auxiliary oil cylinder II, a working solenoid valve, a return flow solenoid valve, a throttle valve, an overflow valve, a one-way valve, an electromotor, a gear pump, a filter, an oil tank and anti-explosion valves. The PC program control soft starting and falling device is characterized in that a solidification program of a PC program circuit board component is predesigned and compiled according to working requirements, the working solenoid valve and the return flow solenoid valve of a hydraulic system of the PC program control soft starting and falling device are controlled by the PC program to act according to the requirement that the automobile elevator needs being buffered in rising starting and lowering stopping processes; the flow of a hydraulic circuit is adjusted to control the rising and lowering speed of the oil cylinders to achieve the purpose of soft starting and falling; and the starting-rising and lowering-resetting processes are stable and safe. According to the PC program control soft starting and falling device, since the starting-rising and lowering-resetting speed of an elevator platform is slow, the soft starting and falling purpose is achieved, and the whole process is stable and safe.
