the lifting hydraulic cylinder 15 and the pushing hydraulic cylinder 23 are hydraulic cylinders, and the hydraulic cylinders are hydraulic actuating elements which convert hydraulic energy into mechanical energy and perform linear reciprocating motion (or swinging motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the effective area; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffering device and an exhaust device. The damping device and the exhaust device are determined according to specific application occasions, and other devices are necessary.

The Motor 35 is an electric Motor, and an electric Motor (Motor) is a device that converts electric energy into mechanical energy. The electromagnetic power rotating torque is formed by utilizing an electrified coil (namely a stator winding) to generate a rotating magnetic field and acting on a rotor (such as a squirrel-cage closed aluminum frame). The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor is different from the rotating speed of a rotor to keep synchronous speed). The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to enable the motor to rotate.

The cylinder 38 is a cylinder, which is a cylindrical metal work that guides a piston to reciprocate linearly in the cylinder. Air converts thermal energy into mechanical energy by expansion in an engine cylinder; the gas is compressed by a piston in a compressor cylinder to increase pressure, and the working principle of the pneumatic cylinder is to convert the potential energy of the compressed air into mechanical energy or kinetic energy of motion of applied force. In the pneumatic cylinder, the two chambers are maintained at different air pressures. The piston (sometimes referred to as a rod) attached to the dividing wall begins to move because the volume of the chamber changes in response to the relative pressures of the two chambers. At least one chamber is connected to a port allowing air to flow in and out of a pneumatic cylinder, the cylinder is required to be connected with a solenoid valve when in use, the solenoid valve is industrial equipment controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator and is not limited to hydraulic pressure and pneumatic pressure. Used in industrial control systems to regulate the direction, flow, velocity and other parameters of a medium. The solenoid valve can be matched with different circuits to realize expected control, and the control precision and flexibility can be ensured. The solenoid valves are various, different solenoid valves play a role in different positions of a control system, the most common solenoid valves are one-way valves, safety valves, direction control valves, speed regulating valves and the like, the solenoid valves need to be connected with a compressed air source and a PLC (programmable logic controller), and the PLC can control the solenoid valves, so that the solenoid valves can control the on-off of air paths to control the air cylinders.
