Description

Technical Field

[0001] This utility model relates to the field of cable shaft construction technology, and in particular to an adjustable support device for cable shafts. Background Technology

[0002] In existing technologies, when installing cables inside a shaft, a U-shaped mounting bracket is fixed to the side wall of the shaft using expansion bolts. The cable tray is then placed on the U-shaped mounting bracket, holes are drilled at the bottom of the cable tray, and bolts are used to fix the cable tray to the U-shaped mounting bracket. The cable is then laid inside the cable tray and fixed to the cable tie inside the cable tray. Finally, the cable tray cover is placed on top to complete the cable laying. However, in actual use, the distance between the U-shaped mounting bracket and the side wall of the shaft is small. When installing the cable tray on the U-shaped mounting bracket, the nuts are difficult to fix due to the space between the U-shaped mounting bracket and the side wall of the shaft, which affects the operation progress. In addition, the existing cable tie is welded inside the cable tray, making the manufacturing process cumbersome. Utility Model Content
