Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a cable sheath cutting device. Background Art

[0002] Power cables are widely used to transmit and distribute electric energy. They are often used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. At present, the trunk lines in the power system are generally used to transmit and distribute high-power electric energy with power cables, including 1-500KV and above various voltage levels.

[0003] In some special scenarios (such as the production of submarine cable heads), a steel ring-type cable sheath is generally used to compress the ends of the power cable. On the one hand, this cable sheath is used to compress the armor of the power cable. On the other hand, it is used to prevent the cable from being subjected to external forces during use, causing the compressed cable copper core to spread out, thereby reducing the risk of power transmission.

[0004] When the power cable is repaired or the cable head is remade, this steel ring type cable sheath needs to be removed.

[0005] The traditional removal method is generally that the operator uses an electric cutting machine to directly cut the cable sheath. However, in actual operation, the applicant found that this traditional cutting method has the following problems:

[0006] 1. The steel ring cable sheath is only connected to the cable protective layer. During the cutting process, it is easy to accidentally damage the cable protective layer due to poor cutting depth control;

[0007] 2. Since the cable is a cylindrical structure, it is not easy to fix, and the steel ring cable sheath is hard, it is easy to slip when the cutting machine is cutting, causing injuries to personnel and cable cuts. In addition, the track is often not straight during cutting, resulting in low cutting efficiency and a lot of time wasted.

[0008] Therefore, there is an urgent need for a cable sheath cutting device to solve the above technical problems. Summary of the invention

[0009] The purpose of the present invention is to provide a cable sheath cutting device to solve the technical problems that the steel ring type cable sheath is only connected to the cable protective layer in the prior art, and the cable protective layer is easily damaged due to poor cutting depth control during the cutting process, and the cable is a cylindrical structure and is not easy to fix. The steel ring type cable sheath is hard and is easy to slip when the cutting machine is cutting, causing injuries to personnel and cable cuts, and the track is often not a straight line during cutting, resulting in low cutting efficiency and a lot of time wasted. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the present invention are described in detail below.
