Automatic retraction mechanism of cables

Abstract

The invention discloses an automatic retraction mechanism of cables. The automatic retraction mechanism is composed of a winding drum, a rotating disc, a stabilizing frame, a reset spring and a ball screw. Two ends of the ball screw are fixed on the stabilizing frame, the reset spring is sleeved on the ball screw, the winding drum is connected with the ball screw through a rolling bearing, the rotating disc is in sliding connection with the winding drum through a sliding groove on the winding drum and is in matched with the ball screw through rolling balls for transmission, and the automatic retraction mechanism resets automatically under thrust of the reset spring, so that the winding drum achieves automatic retraction on cables or pipelines. The automatic retraction mechanism achieves retraction on the cables or pipelines through matching transmission of the rolling balls and the ball screw, achieves automatic reset through the reset spring, requires no additional external force for driving, is simple in structure, small in number of parts, easy to manufacture and assemble, strong in practical applicability, convenient and fast to operate and free of maintenance and greatly reduces production cost.

Description

technical field [0001] The invention belongs to the technical field of cable retraction, and relates to an automatic cable retraction mechanism. Background technique [0002] In the power industry or engineering construction, the use frequency of cables is relatively high, especially in construction machinery and equipment, a large number of connecting cables are often used. Because the cables are long, it often takes a lot of money to undo them after they are deployed or terminated. Time, and need to invest more manpower and material resources. In order to solve the above-mentioned problems, various cable retracting and retracting mechanisms have appeared on the market at present, and these commonly used retracting and retracting mechanisms are mainly used for retracting and retracting pipelines and cables. The retracting mechanism is generally composed of a driver (motor or air motor), a reducer, a reel, and the like. These cable retracting and retracting mechanisms effe...

AI Technical Summary

Problems solved by technology

However, the above-mentioned retractable mechanism has certain requirements on the environment, and the driver retractable mechanism must have a power supply or an air source.

And when retracting and releasing cables or pipelines, the speed of retracting and releasing cables or pipelines should be roughly consistent with that of the driver, otherwise the arrangement of cables or pipelines will be disordered and the cables or pipelines will be damaged

The third is that the retractable mechanism driver and reducer have no braking device, which will cause cables or pipelines to be scattered during transportation.

Moreover, most of these cable retracting mechanisms have complex structures, difficult maintenance, and high production costs.
