Abstract

The invention discloses a novel movable support type heavy-duty drag chain, relates to a novel movable support type heavy-duty drag chain which has the functions of centralized supporting, reciprocating movement traction and protection for various conveying pipes and cables of electric energy, hydraulic pressure, pneumatic power, liquid raw materials and the like of metallurgical steel rolling equipment, large-sized mechanical equipment and large-sized automatic production lines in continuous operation. The drag chain is characterized in that: one surface of a drag chain body consists of a group of powerful torsion springs and the other surface of the drag chain body consists of a plurality of freely adjustable chain rails to replace a thick and heavy chain plate which is formed by stamping and welding two layers of steel plates in the prior art; and a pipe / cable supporting bridge plate and a partition plate which are integrated with each other are used for replacing a supporting plate in the prior art. A manufacturing process can be performed without a series of stamping and carrying moulds and equipment with high cost. The key point of the invention is that: the drag chain can be bent and moved by elastic deformation of the torsion springs, and reverse acting force of the torsion springs is skillfully utilized to obviously relieve load and wear on a connection part of the drag chain. The drag chain is also characterized in that: the freely adjustable chain rails of the drag chain body and a roller or roller assembly which has the same bending radius as the drag chain and is provided with a tooth socket are adopted to movably support the drag chain to operate with heavy duty. The drag chain solves the problems of heaviness and unreasonable supporting of the heavy-duty drag chain in the prior art, and overcomes the disadvantages of quick wearing of a heavy-duty drag chain plate hole and a pin shaft in the prior art.

Description

technical field

[0001] The invention relates to a new type of heavy-duty mobile support for the reciprocating mobile traction and protection purposes of centralized load-carrying of electric energy, hydraulic pressure, pneumatic and liquid raw materials, etc., for metallurgy, shipbuilding, large-scale mechanical equipment, and large-scale automatic production lines. drag chain. Background technique

[0002] The chain plates on both sides of the structure of the heavy-duty towline in the prior art are welded with double-layer stamped steel plates after stamping of the plate, because the limitation of the support mechanism is to ensure the carrying capacity and free suspension capacity of the heavy-duty towline, and ensure Sufficient rigidity and strength often make the chain plate parts of the drag chain strong and heavy. After using a large number of working umbilical cables, the entire drag chain is very heavy, because the contact surface between the chain plate hole and th...
