Description

TECHNICAL FIELD

[0001] The utility model relates to a drag chain structure technical field, concretely relates to a mixed installation aerial work platform drag chain. BACKGROUND

[0002] The drag chain plays a traction and protection role to the cable, oil pipe, gas pipe and water pipe built in the machine, and makes the whole machine look more beautiful. It is mainly used for pipeline protection of the aerial work platform or telescopic arm, and makes it reciprocate. The conventional drag chain is divided into two categories of steel drag chain and plastic drag chain according to the material type. The inner and outer layer connecting pieces of the conventional drag chain are bolted.

[0003] The drag chain is composed of multiple chain link structures, and the adjacent two drag chain links can rotate by a certain angle. In long-term use, if the structural strength of the drag chain link is not high, damage is prone to occur, and in the rotation use of the adjacent two drag chain links, the arc-shaped slide rail limiting is generally used, and when the sliding block slides in the arc-shaped slide rail, impact is prone to occur, which on one hand causes noise, and on the other hand causes damage to the sliding block and the arc-shaped slide rail. SUMMARY

[0004] The utility model mainly solves the deficiency in the prior art, provides a mixed installation aerial work platform drag chain, it has simple structure, high strength and good use effect characteristics. Solve the problem that the steel drag chain needs many quality heavy pin shafts and the plastic drag chain is low in strength. Realize the role of protecting the equipment cable pipeline.

[0005] The above technical problems of the utility model are mainly solved by the following technical scheme:

[0006] A mixed installation aerial work platform drag chain, comprising.

[0007] As preferred, a plurality of drag chain links are connected to form a shape, the drag chain link comprises a pair of steel chain plates II, the outer side of the front end of the steel chain plate II is provided with a steel chain plate I, the side of the steel chain plate I and the steel chain plate II is provided with a nylon chain plate, and the nylon chain plate is connected with the steel chain plate I and the steel chain plate II.

[0008] As preferred, the connection structure of the nylon chain plate and the steel chain plate I and the steel chain plate II adopts an integral stretching pin of the steel chain plate I and the steel chain plate II matched with an integral pin of the nylon chain plate.

[0009] As preferred, the upper and lower parts between the steel chain plates II are provided with nylon crosspieces. The nylon crosspieces play a supporting and protecting role on the cable pipeline.

[0010] As preferred, the nylon chain plate is provided with an insertion buckle block corresponding to the insertion of the steel chain plate II and the nylon crosspiece.

[0011] The utility model discares the following effects:

[0012] The utility model provides a kind of mixed installation aerial work platform tow chain, compared with prior art, with simple structure, high strength and good use effect characteristics.The problem of multiple quality heavy pin shaft required by steel tow chain and low strength of plastic tow chain is solved.Mixed installation structure of nylon chain plate and steel chain plate is adopted, and nylon chain plate installed on the outside effectively prevents external force rubbing chain plate and destroying steel chain plate surface treatment protective layer.

[0013] Pipeline of aerial work platform or telescopic arm is actually in suspended state in equipment use, increase tow chain to make pipeline built-in, protect pipeline from being drawn to prevent abrasion.Nylon chain plate and steel chain plate combination, under the same specification, higher strength than pure plastic tow chain, lighter than pure steel chain.
