Introduction to the hydraulic pull-out device: The hydraulic pull-out device is a special tool suitable for daily maintenance and repair of railway lines. It has two functions of lifting and pulling out the rail. It has a simple structure, easy operation, high efficiency, does not invade boundaries, and is safe and reliable to use. It is an ideal tool for railway operations.
The working principle of the hydraulic puller:
The hydraulic puller is composed of a cylinder, a cylinder base, a fuel tank, a plunger pump, a bracket, a base and a handle. The base, bracket and cylinder seat are hinged with pins to form a planar four-bar linkage mechanism. The oil cylinder seat is equipped with safety valve, oil return valve and other mechanisms. Move the control rod to allow the high-pressure oil generated in the plunger pump to enter the oil cylinder, pushing the piston to extend. Under the action of the piston thrust, the oil cylinder and the bracket rotate upward around the pin on the base at the same time, creating a vertical motion at the hinge of the starting wheel. The upward thrust also generates a horizontal thrust on the top block of the bracket, thereby achieving the purpose of starting and pulling out of the track.
