It can neatly arrange and fix cables to avoid cable confusion and damage, and it is also convenient for cable maintenance and management. The characteristic of the ladder cable tray is its unique ladder design, which makes it have good ventilation performance and helps the heat dissipation of cables. At the same time, the ladder cable tray also has the advantages of light weight, low cost and easy installation, so it has been widely used in cable laying. Hot-dip galvanized steel is a steel that has been treated with hot-dip galvanizing process, which has excellent corrosion resistance and durability.

[0003] In order to facilitate cable laying, a hot-dip galvanized steel ladder-type cable tray is required.

On the other hand, the existing ladder cable tray is usually only provided with a single-layer support arm. In some narrow environments, a single-layer cable tray is not enough to support a sufficient number of cables, and there is not enough space to lay multiple cable trays. Therefore, a hot-dip galvanized steel ladder cable tray is proposed to solve the above problems. Utility Model Content

A T-shaped slot 11 is opened inside the reinforcing rib 10, and a group of limiting holes 12 are opened on the upper and lower sides of the reinforcing rib 10, respectively. The limiting holes 12 are provided in four groups. A group of limiting holes 12 are distributed in the upper and lower sides of the reinforcing rib 10. A T-shaped block 13 is symmetrically arranged inside the T-shaped slot 11 and is slidably connected.

[0034] Working principle: When you want to reduce the vibration of the cable, the vibration is transmitted to the hanger 1, and the hanger 1 vibrates up and down, driving the fixed plate 2 to vibrate, compressing the first shock-absorbing spring 4 and the second shock-absorbing spring 5, which absorb the vibration and generate compression, and then release it, driving the shock-absorbing column 3 to slide up and down in the sliding sleeve 6. The shock-absorbing column 3 drives the rubber shock-absorbing ring 8 to slide up and down. The rubber shock-absorbing ring 8 is deformed and extruded, and slides to the adjacent shock-absorbing groove 7, generating a larger resistance to offset the vibration transmitted by the spring, thereby reducing vibration and protecting the cable surface. When you want to add a cable tray in a narrow place, press the threaded sleeve 17 up and down, the threaded sleeve 17 slides into the limiting groove 15, and at the same time squeezes the limiting spring 16 to slide the T-block 13 into the T-slot 11. When the threaded sleeve 17 contacts the limiting hole 12, the threaded sleeve 17 is not subject to force, and the limiting spring 16 pushes the threaded sleeve 17 upward and snaps into the limiting hole 12. Screw the bolt 18 into the threaded sleeve 17 to fix the T-block 13 and the auxiliary support arm 14 inside the hanger 1, so that more cables can be laid.
