Constant tension type cable reel device with flexible cable take-up

Abstract

The invention relates to cable winding equipment and in particular relates to a constant-tension type cable drum device capable of flexibly winding a cable. The constant-tension type cable drum device comprises a drum, wherein the drum is connected with a speed adjustment device through a drum shaft in a transmission manner; the speed adjustment device comprises a box body and a planetary differential transmission mechanism arranged in the box body; the planetary differential transmission mechanism comprises an input shaft arranged on the box body in a rotatable manner, a speed adjustment shaft and a planetary frame; a braking mechanism is arranged between the speed adjustment shaft and the box body and comprises a rotary friction disk and a mobile friction disk; a compression spring jacks one side of the mobile friction disk; furthermore, the mobile friction disk is connected with an adjustment mechanism in a transmission manner; the adjustment mechanism comprises an adjustment seat and a pressing disk; a mobile gear is arranged on the drum shaft in a rotation-stopping manner and is also connected with a shifting rod in a transmission manner; the planetary differential transmission mechanism is connected with the drum shaft through the planetary frame in a transmission manner. According to the constant-tension type cable drum device capable of flexibly winding the cable, the problem that the cable is damaged by the conventional cable drum device is solved.

Description

technical field

[0001] The present invention relates to cable take-up equipment, in particular to a constant tension type cable reel device capable of flexible take-up. Background technique

[0002] The cable reel device, as the name suggests, is mainly used for retracting and releasing cables. It is widely used to provide power supply, control power supply or control signal for mobile devices.

[0003] The current cable reel device mainly includes a reel and a slipping mechanism, wherein the slipping mechanism mostly adopts a friction clutch, a hydraulic coupler, a magnetic coupler, a stall torque motor, etc., and is arranged in the reel.

[0004] In use, the reel is mounted on and travels with the mobile device. When the cable is taken up, the winding speed of the reel is greater than the walking speed of the mobile device, and the sliding mechanism is used to keep the winding speed of the reel consistent with the walking speed of the mobile device, so that the cable is ...
