Insulating winding device for steel cable and manufacturing process of winding drum assembly

Abstract

The invention discloses an insulating winding device for a steel cable and a manufacturing process of a winding drum assembly. The insulating winding device for the steel cable comprises a driving shaft, a chamber, a spline pair flange, the steel cable, the winding drum assembly, a guide nut, an adjusting ring, a nut supporting barrel, a shaft end cover, a bearing, a plug, an elastic roller assembly, a bearing gland, screws and a shaft seal. The winding drum assembly comprises a winding drum body, an isolating ring, an isolating sleeve, a winding sleeve, a press plate, a flat head screw, a cylindrical head screw, a flat washer and a T-shaped sleeve. Insulating materials are reasonably used, ingenious structure combination is adopted, and equipment achieves an insulating effect while guaranteeing mechanical performance. The insulating winding device for the steel cable and the manufacturing process of the winding drum assembly can be applied to universal hoisting equipment, can also be applied to winding equipment with special requirements, and are particularly suitable for hoisting equipment required by precise experiments in laboratories, so that the situation that micro electricity generated due to magnetic induction and friction gathers at the tip end of a hook connected with the steel cable and affects the performance index of a hoisted object is prevented. The device is simple in structure and good in insulating performance.

Description

technical field [0001] The invention relates to the field of mechanical lifting equipment and mechanical manufacturing, in particular to a manufacturing process of an insulating steel cable hoisting device and a hoisting drum assembly. Background technique [0002] From an accidental electric leakage accident in the laboratory, I thought whether the hook of the hoist was charged when it was working normally. After testing, the lifting hook and the steel cables connected to it were charged to varying degrees, especially the tip of the lifting hook. Although the existing electricity is not enough to endanger life, it will affect the experimental results for some experiments that are sensitive to current. For example, when cultivating crystal growth, the inoculation rod is pulled. If the inoculation rod is charged to form a current, the crystal growth will be disordered. To analyze the conditions and reasons for the formation of electric current, and to cut off the possible cir...

Problems solved by technology

After investigation, the hoist and lifting device usually used do not have the function of insulation. Even if the hoist with special requirements has the function of insulation, it is still miniature, and it cannot be made larger, because the current insulation materials do not have any kind of insulation that can be compared with metal materials. mechanical properties compared to
