Problems solved by technology

[0002] The drag mechanism in the existing mechanical equipment mostly uses electric power as the power source of the entire drag mechanism, dragging the equipment to move in a straight line in the horizontal direction. This kind of drag mechanism has a large structure and is inconvenient to assemble, and is not suitable for ships or Underground and other special working places
In addition to electricity, there are also hydraulic cylinders used as the power source of the dragging mechanism. Since the hydraulic cylinder can perform reciprocating motion, the reciprocating motion of the hydraulic cylinder can be used to drag heavy objects or other functions related to the reciprocating motion of the oil cylinder. , but due to the limited length of the existing oil cylinders on the market, long-distance dragging motions cannot be realized, resulting in limited use of the dragging mechanism

Abstract

The invention belongs to the technical field of dragging machines, and particularly relates to a horizontal chain type dragging machine driven by an oil cylinder. The machine comprises a chain and a telescopic mechanism, wherein a hollow cavity is formed in the center of a piston rod of the telescopic mechanism, the end of the piston rod is connected with a tensioning lock cylinder, the chain penetrates through the hollow cavity of the piston rod and the tensioning lock cylinder, and the tensioning lock cylinder locks or loosens the chain to enable the chain to move along with movement of thepiston rod. The chain type dragging machine is small in size, high in dragging force, capable of achieving long-distance dragging, simple in structure and convenient to use.
