Description

Technical Field

[0001] The invention relates to the field of elevator accessories, in particular to an elevator cable clamping device and an elevator cable clamping structure. Background Art

[0002] At present, a large number of cables are usually arranged in elevators. Among them, several elevator cables are usually arranged together to reduce the difficulty of routing. Since there is no limit device between the existing elevator cables, when a large number of elevator cables are arranged together, the elevator cables are prone to entanglement with each other, making the elevator cables very messy.

[0003] This makes it difficult to repair or replace one of the elevator cables, which easily increases the difficulty of maintaining the elevator cables.

[0004] Although multiple elevator cables are now bundled together with strapping tape,

[0005] However, since the strapping tape is difficult to directly remove, when the elevator cable needs to be repaired or replaced, the strapping tape is generally cut directly, and then after the repair or replacement is completed, a new strapping tape is used to bundle multiple elevator cables together. It can be seen from this that the strapping tape is difficult to reuse, which easily leads to an increase in the maintenance cost of the elevator. Summary of the invention
