Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a supporting device for laying underground cables. Background Art
[0002] To ensure orderly installation of cable lines, cables are typically laid underground. After laying the cables in the underground shaft, they need to be secured to the shaft wall to prevent disorganization. Existing techniques typically involve drilling holes in the shaft wall and installing expansion screws. A cable clamping device is then attached to the expansion screws, which are then used to clamp the cables. Cable expansion screw fixing is a common method for securing cables, particularly suitable for environments requiring high strength and stability, such as cable shafts and cable trays. Expansion screw fixing utilizes a wedge-shaped slope to promote expansion, generating frictional gripping force, thereby achieving a secure connection. An expansion screw consists of a screw and an expansion tube. The end of the screw is conical, with the larger diameter of the cone being larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the axial movement of the threads causes the cone to move, creating positive pressure on the outer circumference of the expansion tube. This creates frictional self-locking between the wall, the expansion tube, and the cone, achieving a secure connection.
[0003] The effectiveness of expansion screws is directly affected by the quality and condition of the substrate (e.g., wall, bracket, etc.). If the substrate is loose, fragile, or damaged, the expansion screws may not provide sufficient holding force, thus affecting the stability of the cable. In the case of poor-quality substrates, the cable may become loose or even fall off due to inadequate fixing, posing a threat to the normal operation of the cable system.
[0004] Furthermore, once the expansion screw is fixed, its expanded portion will fit tightly into the hole in the base material, forming a fixed grip. However, this fixing method is usually a one-time fixation method. That is, once the expansion screw is fixed, it is difficult to remove it again without damaging the base material or the screw itself.
[0005] Secondly, since the expansion screws cannot fill the wall after being embedded in the wall, there will be holes inside, which will affect the load-bearing capacity of the wall. Utility Model Content
