Description

Drag chain

Technical Field

The utility model belongs to the technical field of the tow chain equipment, especially, relate to a tow chain.

Background

At present, the drag chain has been widely applied to a great deal of fields such as digit control machine tool, stone material machinery, glass machinery, door and window machinery, injection molding machine, manipulator, jack-up transportation equipment, automatic warehouse, the drag chain can play traction and guard action to built-in cable of machinery, oil pipe, trachea, water pipe etc. makes the whole more pleasing to the eye that looks of machinery simultaneously. The drag chain of prior art comprises a plurality of main part link joint more, and the drag chain can be divided into the triplex according to the motion state when using: the lower section of the drag chain, the turning ring section and the upper section of the drag chain. The existing drag chain is small in hanging bearing capacity, when the length of the drag chain is long, the drag chain can be bent to different degrees under the action of the self weight and the built-in cables and pipelines, and the built-in cables and pipelines of the drag chain can be damaged by the bending phenomenon. If the drag chain is stressed too much, the upper section of the drag chain is even superposed on the lower section of the drag chain, which is commonly called as waist collapse, if the upper section of the drag chain continuously rubs with the lower section of the drag chain for a long time, not only can the built-in line be damaged, but also the drag chain can be seriously worn, the phenomena of disconnection and fracture of the drag chain are caused, and the service life of the drag chain is seriously shortened.

The existing solutions to the above technical problems are generally: a follow-up supporting mechanism which moves along with the drag chain is arranged below the long-distance drag chain to support the long-distance drag chain and avoid the waist collapse phenomenon. Although the following support mechanism solves the technical problem that the towline collapses the waist, the following defects still exist:

firstly, for a long-distance drag chain, the length of a drag chain follow-up support matched with the drag chain is also longer, and the follow-up support of the long-distance drag chain not only has high manufacturing cost and large difficulty in later management, but also is not high in stability and very easy to break down.

The follow-up supporting mechanism is only suitable for the long-distance drag chain to run under the low-speed state, and when the long-distance drag chain reciprocates under the high-speed state, the phenomenon that the drag chain is partially disconnected can be caused, and under the long-time high-speed state motion state, the follow-up supporting mechanism is great to the wearing and tearing of drag chain, can seriously influence the operational reliability of drag chain, shortens the life of drag chain.

In conclusion, how to design a drag chain which does not collapse down in long-distance turnover work, has long service life and ensures quality becomes a technical problem which needs to be solved urgently.
