Problems solved by technology

[0002] With the strong momentum of my country's economic growth promoting the rapid development of infrastructure, the demand for construction of large ports, large hydropower stations, and cross-river and sea bridges continues to increase, driving the demand for large-tonnage, high-lift large cranes in these infrastructure constructions. Demand, and the drum is a key typical component in the crane wire rope winding system. When designing the hoisting mechanism of these large-tonnage, high-lift large cranes, it is found that the traditional spiral drum can no longer meet the requirements of multi-layer winding. However, the appearance of the parallel folding line reel has improved the above situation, but due to the special arrangement of the grooves on the surface of the parallel folding line reel, it is difficult to improve the performance of the surface and grooves, so it is urgent to solve the problem of parallel folding line multilayer reel high-quality surface treatment

Abstract

The invention discloses a surface treatment process of parallel-broken-line multilayer rope winding drum. The surface treatment process specially comprises the following steps that a winding drum body is preheated to reach 80-120 DEG C; the winding drum is turned, and meanwhile heat preservation sand is sprayed towards the preheated winding drum body, and the spraying time is 5-10 minutes; wrapping heat preservation is conducted by adopting steel ropes along parallel-broken-line grooves formed in the surface of the winding drum, the heat preservation time is 2-4 hours, then the steel ropes are loosened, and the heat preservation sand is removed; the winding drum is turned, meanwhile an oxidation-resistant and abrasion-resistant coating is sprayed to the surface of the winding drum body, and finally a firm oxidation-resistant and abrasion-resistant layer formed on the surface of the drum body. In the mode of dual heat preservation based on the heat preservation sand and steel rope wrapping, the heat treatment quality of the parallel-broken-line grooves formed in the surface of the winding drum can be improved, meanwhile the follow-up spayed oxidation-resistant and abrasion-resistant coating can be rapidly cured, the spraying quality can be improved, and finally the surface of the winding drum body can have excellent abrasion resistance, oxidation resistance and higher hardness.
