Problems solved by technology

[0004] The purpose of the present invention is to improve and innovate the problems existing in the background technology, to provide a cable reel that can be used for high-frequency and high-speed cable rewinding, and to use the characteristics of the vortex spring to solve the problem of cable reel rewinding and unwinding. When the impact torque is too large, the tension of the cable fluctuates greatly, so the use is safe and reliable, and the service life of the cable is greatly extended.

Embodiment Construction

[0018] The present invention will be further described below according to the accompanying drawings and specific examples.

[0019] Depend on figure 1 It can be seen that the present invention is mainly composed of a reel 1, a cable 2, a reduction box 5, a vortex spring 4, a drive unit 8, and a conductive slip ring box 9. The drive unit 8 adopts a hysteresis coupling drive, a hydraulic coupling drive or a variable frequency motor, etc. Flexible drive system. The drive unit 8 is connected to the reduction box 5 through bolts, the gear or sprocket 7 is installed on the output shaft of the drive unit, and is connected to the flange 6 in the reduction box through gear transmission or chain transmission, and the flange 6 is connected to the vortex spring cover 10 Through bolt connection, the inner hook and outer hook of the scroll spring are respectively connected with the spring cover 10 and the output shaft 3 of the reduction box. The output shaft 3 of the reduction box has a fl...

Abstract

The invention discloses a cable winding drum under the condition of high-frequency high-speed winding and unwinding. The cable winding drum is composed of a reel, a reduction gearbox, a drive unit anda conductive slip ring box. The cable winding drum is characterized in that the drive unit is a flexible drive system, the drive unit is connected with the reduction gearbox through gear transmissionor chain transmission, and a volute rotation spring is installed on the output shaft of the reduction gearbox. The cable winding drum is suitable for a high-frequency high-speed winding and unwindingcable, so that the problem that the tension fluctuation of the cable is large due to overlarge impact torque during winding and unwinding of the cable winding drum is solved, the cable winding drum is safe and reliable, and the service life of the cable is greatly prolonged.

Description

technical field [0001] The invention relates to a cable reel, in particular to a cable reel for high-frequency and high-speed rewinding and unwinding of cables. Background technique [0002] At present, the cranes used for loading and unloading (such as container cranes, grab cranes and other spreaders, etc.) all require high efficiency, so the cable reels that supply power to them also need to have high-speed and efficient operation. At present, the combination drive of three-phase asynchronous motor and hysteresis coupling or the combination drive of three-phase asynchronous motor and hydraulic coupling or the combination drive of frequency conversion control and frequency conversion motor are mostly used as the drive unit of the cable reel. These drive units can achieve the required winding speed and winding torque, and also have the overload protection function for the cable. However, in the process of reeling and unwinding the cable, especially at the moment of start-u...
