Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lifting hangers, more particularly, it relates to a lifting and hoisting system for four-fluorine metal hose production. BACKGROUND

[0002] The four-fluorine metal hose is a composite hose combining the characteristics of polytetrafluoroethylene (PTFE, commonly known as "Teflon") and metal materials, which has corrosion resistance, high temperature resistance, flexibility and pressure resistance, and is widely used in chemical, pharmaceutical, food, semiconductor and other industries. It is composed of an inner liner, a reinforcing layer and an outer layer. The PTFE dispersion liquid is sprayed on the surface of the inner liner to give the inner liner corrosion resistance, non-stickness and low friction.

[0003] During the transfer of the metal hose, the metal hose needs to be lifted and transferred by using a lifting hanger. When the metal hose is lifted and hoisted, the metal hose is prone to excessive falling and excessive bending deformation, and then pipe body damage and safety accidents occur.

[0004] At the same time, during the spraying production of the inner wall of the metal hose, the metal hose is usually placed flat on the processing table, the connecting flanges at both ends of the metal hose are fixed, the spray head is inserted into the metal hose for spraying, however, the metal hose body is not effectively supported and protected, and the metal hose is prone to fluctuation during spraying, affecting the normal spraying and reducing the spraying quality.

[0005] The above-mentioned clamping of the metal hose for transfer and spraying production is operated separately, and the metal hose needs to be repeatedly taken by human, which is complicated and reduces the work efficiency.

[0006] Therefore, it is necessary to design a lifting hanger that integrates safety hoisting and spraying protection. SUMMARY

[0007] In view of the deficiencies of the prior art, the purpose of the present application is to provide a lifting and hoisting system for four-fluorine metal hose production. When the lifting hanger is in the lifting state, the upper half holding pipe and the lower half holding pipe are kept separate and unfolded, which facilitates the placement and taking of the metal hose, and the metal hose is hoisted and transported to avoid falling and deformation. When the lifting hanger is not in the lifting state, the linkage between the components drives the groups of upper half holding pipes to descend and cover the corresponding lower half holding pipes synchronously, completing the synchronous protection and clamping of the groups of metal hoses, preventing the metal hose from fluctuating during subsequent spraying, and improving the spraying quality.
