Rotary drum device capable of automatically winding and unwinding cable

Abstract

The invention discloses a rotary drum device capable of automatically winding and unwinding a cable. A rotary drum shaft is sleeved with a rotary drum end gearwheel, a rotary drum and an anti-explosion junction box; the anti-explosion junction box is fixedly connected with a bearing support on one side; a slip ring, an AC contactor and a breaker are arranged in the anti-explosion junction box; an encoder is arranged at one end of the rotary drum shaft; the rotary drum and the rotary drum end gearwheel are coaxially and fixedly connected; the rotary drum end gearwheel is in meshing transmission connection with a motor end pinion; a gear protection cover is arranged on the outer surfaces of both the rotary drum end gearwheel and the motor end pinion; the motor end pinion is coaxially connected with an AC asynchronous motor through a torque transducer; and the AC asynchronous motor, the encoder, the torque transducer, the AC contactor and the breaker are all connected with an anti-explosion motor control cabinet. The rotary drum device provided by the invention effectively avoids excessive cable being damaged caused by friction or abrasion by other equipment.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a roller device with automatically retractable cable length. Background technique [0002] At present, in order to meet various heavy-duty production needs, large-scale hoisting and drilling machinery have appeared in rail-type and transport-type methods. For example, most of the gantry cranes are rail-type, which requires frequent mobile hoisting machinery and equipment. The mobile power supply of the crane is One of the first problems to be solved; there are also large-scale artificial island drilling rigs that are also orbital, requiring the drilling rig to move on a large circular track to complete the drilling of multiple wellbores, requiring a large number of power supply cables and control cables to follow during the control process Mobile needs to set up a large number of busbars or use mobile power supply equipment, etc., which is difficult to control cost and...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a roller device with automatically retractable cable length, which solves the problems in the prior art that a large number of bus bars need to be erected or mobile power supply equipment is used, which requires a lot of cost and time, and the work efficiency is low
