[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 A cable protection device for a magnetic chuck crane, installed on the hanger 2 of the magnetic chuck crane 1, is used to protect the cable 3, comprising:

[0033] The protective cylinder 4 is installed on the hanger 2, and the lower end of the cable 3 passes through the protective cylinder 4 and is connected to the electrical equipment on the hanger 2;

[0034] The limiting cage 5 is installed at the upper end of the protective cylinder 4;

[0035] Support 6 is located inside the protective cylinder 4, and a guide clamp 7 is provided on support 6 to guide the cable 3 in one direction;

[0036] The transmission mechanism 8 is mounted on the support 6 and is used to drive the guide clamp 7 to rotate.

[0037] In use, the protective cylinder 4 is installed on the hanger 2 of the magnetic chuck 1, so that the cable 3 leading down from the top of the magnetic chuck 1 falls into the protective cylinder 4, and the lower end of the cable 3 passes through the bottom of the protective cylinder 4 and connects to the electrical equipment on the hanger 2. When the lifting device of the magnetic chuck 1 moves the hanger 2 up and down, the end of the cable 3 will also move up and down. However, when rising, the cable 3 will fall into the protective cylinder 4, which avoids the cable 3 from dangling outside and rubbing or getting tangled with the hanger 2 or other mechanical parts, greatly preventing the cable 3 from wearing out or even breaking. The effect is good. At the same time, the limiting cage 5 can further guide and restrict the cable 3, which can effectively prevent the cable 3 from falling outside the protective cylinder 4 during the lifting process, better ensuring that the cable 3 falls into the protective cylinder 4, which has high practicality and improves the safety and reliability of equipment operation.

[0038] Furthermore, the cable 3 falling into the protective cylinder 4 will pass through the guide clamp 7. When the end of the cable 3 rises and falls together with the hanger 2, the transmission mechanism 8 will simultaneously drive the guide clamp 7 to rotate smoothly. The guide clamp 7 will guide the cable 3 to rotate around the axis of the protective cylinder 4, so that when rising, the cable 3 will fall into the protective cylinder 4 in an orderly and circular shape. When falling, the cable 3 in the protective cylinder 4 will move out in an orderly and circular shape. This allows the cable 3 inside the protective cylinder 4 to be neatly introduced, arranged and led out, further reducing the wear of the cable 3 and preventing the cable 3 from tangling and knotting inside the protective cylinder 4. This better protects the cable 3, significantly improves the service life and effectiveness of the cable 3, and has good performance. It can be widely promoted and used.
