Problems solved by technology

At this time, the number of turns that needs to be rotated is relatively large when the cable reel is retracted and unwound. Considering that the winding length of a single scroll spring is limited, it is difficult to meet the demand for the number of turns of the reel. Therefore, the existing cable reel A plurality of scroll springs in series are usually set inside, thereby increasing the total winding length of the scroll springs, which also makes this kind of cable reel costly, bulky and heavy

Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Various preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] See figure 1 with figure 2 , which shows the structure of the cable drum provided by the embodiment of the present invention. The cable reel includes:

[0031] The reel casing 9, and the scroll spring 2 and the planetary reduction mechanism 8 arranged in the reel casing 9;

[0032] The input end of the planetary reduction mechanism 8 is connected with the reel casing 9 , and the output end is connected with the free end of the scroll spring 2 .

[0033] The cable reel provided in this embodiment is a spring-driven type. The difference between it and the existing cable reel is that it is provided with a planetary reduction mechanism 8, that is, the rotation of the r...

Abstract

The invention discloses a cable reel and a piece of engineering machinery. The cable reel comprises a reel housing, and a scroll spring and a planet deceleration mechanism which are arranged in the reel housing. The input end of the planet deceleration mechanism is connected with the reel housing, and the output end of the planet deceleration mechanism is connected with the free end of the scroll spring. The cable reel can reduce the number of scroll springs while ensuring the reeling length of a cable. Compared to the scroll spring, the planet deceleration mechanism is quite light in weight, quite small in size and quite low in cost. Therefore, the whole cable reel correspondingly has the advantages of low cost, light weight and small size.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a cable drum and construction machinery. Background technique [0002] The cable reel is a cable winding device that provides power supply, control power supply or control signal for large mobile equipment. Cable reels are widely used in heavy engineering machinery such as cranes and ship loaders due to their small installation space, convenient maintenance, and reliable use. [0003] According to the drive form, the cable reel can be divided into spring drive type and motor drive type. Among them, the spring-driven cable reel is used to control the winding and unwinding of the cable, and the spring-driven type is mostly used on the crane. This kind of cable reel is equipped with a scroll spring in the cylinder. When the rope is released, the cylinder rotates to drive the scroll spring to stretch, and when the rope is retracted, the scroll spring returns to drive the drum ...
