Tension member and preparation method and engineering machinery thereof

Abstract

The invention discloses a tension member and the preparation method and the engineering machinery of the tension member. The tension member comprises a middle part and connecting parts, wherein the middle part comprises a carbon fiber composite material body, the connecting parts are arranged at two ends of the middle part, and each connecting part comprises a core part and a carbon fiber carbon fiber layer covering the surface of the core part. The tension member is mainly made of carbon fiber composite materials. The carbon fiber composite materials have the advantages of being low in density, high in axial strength and modulus, and good in fatigue durability. Therefore, weight of the tension member is lowered, and tensile strength and load-carrying property of the tension member are improved at the same time. The tension member has the advantages of being light in weight, and convenient to detach, install and transport. When the tension member is applied to a crane, hoisting capacity of the crane in large radius working conditions can be guaranteed. Besides, the tension member is high in strength and modulus, and the load-carrying property of the tension member is higher than that of an existing steel wire rope or a steel plate or steel tube.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a tension member, a preparation method thereof and construction machinery. Background technique [0002] Tension member is one of the important parts of construction machinery, which is used to transmit force. Especially in the field of cranes, such as crawler cranes and offshore engineering cranes, tension members are indispensable. In the prior art, commonly used tension members are mainly steel wire ropes, steel plates and steel pipes. [0003] In recent years, with the rapid development of engineering construction, the large-scale of the project is accelerating, which makes the construction machinery also develop towards large-scale. The enlargement of construction machinery also puts forward higher requirements on the load capacity of tension members. In order to provide a matching bearing capacity, the existing tension member usually needs to increase its own size, ...

AI Technical Summary

Problems solved by technology

In addition, for cranes with a large operating radius, the gravity of heavy tension members, such as steel wire ropes, steel plates, and steel pipe structures, will greatly consume the lifting capacity in the large radius range, which restricts the large radius capacity of the crane

[0004] Therefore, existing tension members have the disadvantages of low load capacity and heavy weight
