Description
Technical Field
The utility model relates to the technical field of drag chain structures, in particular to a high-bearing steel fully-closed drag chain.
Background
At present, drag chains are widely applied to the fields of numerical control machines, stone machinery, glass machinery, door and window machinery, injection molding machines, hoisting and transporting equipment, automatic warehouses and the like. The drag chain can play the effect of drawing and protecting the built-in cable of machinery, oil pipe, trachea, water pipe etc. makes the whole more pleasing to the eye of machinery simultaneously. The existing drag chain is formed by connecting a plurality of drag block groups, and when the drag chain is used, the drag chain can be divided into three parts according to the motion state of the drag chain: the lower section of the drag chain, the turning ring section and the upper section of the drag chain.
With the improvement of the automation degree of the existing equipment, some original occasions needing manual operation are not suitable for manually controlling the reciprocating motion of the moving parts, for example, a roller conveying trolley under a buggy ladle in a steelworks steel-making workshop is originally used for withdrawing a cable and a feeding pipeline through a manual winch, so that the withdrawing speed is changed too greatly and is under the buggy ladle, the operation risk is extremely high, molten steel falls off by using a drag chain, so that the drag chain has no way to be used, and only the drag chain with excellent sealing performance and high temperature resistance can be used.
When an existing drag chain is used for installing cables, oil and gas pipes and the like, cables are required to penetrate from one end of an annular structure of the drag chain to the other end frequently, and finally the whole cables are limited in a long-strip drag chain, so that the drag protection effect of the cables is achieved.
Disclosure of Invention
The utility model mainly solves the defects of complex structure, low strength and short service life in the prior art, and provides a high-bearing steel fully-closed drag chain which has the characteristics of compact structure, high strength and long service life. And the stability of cable protection is improved through the totally-closed cover plate.
The technical problem of the utility model is mainly solved by the following technical scheme:
a high-bearing steel totally-enclosed drag chain comprises a movable end fixing frame and a fixed end connecting frame, wherein a plurality of drag chain components which are fixedly connected through pin shafts are arranged between the movable end fixing frame and the fixed end connecting frame. The drag chain assembly comprises a closed inner side cover plate, a plurality of steel chain plates which are vertically connected and fixed with the closed inner side cover plate in an inserting and embedding manner are arranged at the upper end of the closed inner side cover plate, a rotating pin shaft which is connected and embedded with the steel chain plates is arranged between the adjacent drag chain assemblies, and closed outer side cover plates which are connected and fixed with the steel chain plates in an inserting and embedding manner are arranged at the upper ends of the two adjacent steel chain plates.
Preferably, the side edges of two adjacent steel chain plates are respectively provided with a separation frame which is vertically connected and fixed with the closed inner side cover plate in an inserting manner, and the steel chain plates are fixedly connected with the separation frames through bolts.
Preferably, the movable end fixing frame and the fixed end connecting frame both comprise connecting shafts inserted with the drag chain assembly, and a plurality of fixing plates which are in compression joint with the steel chain plates and are sleeved with the connecting shafts are arranged on the connecting shafts.
Preferably, the cross section of the fixing plate is in an L-shaped structure.
The utility model can achieve the following effects:
compared with the prior art, the high-bearing steel totally-enclosed drag chain has the characteristics of compact structure, high strength and long service life. And the stability of cable protection is improved through the totally-closed cover plate.
