Problems solved by technology

Due to the structural design and manufacturing process of the previous movable support, the cross arm often fell off under the action of external force, causing the laid cable to fall, and this type of support component could not bear the heavy weight of the cable (such as the commonly used in urban power grid) 10KV power cable), so the scope of use of this movable cable support is greatly limited, only limited to the laying of weak current cables with a small weight
As mentioned above, there is a certain distance between the cross arms of the existing cable support, so the number of laid cables is also subject to certain restrictions.

Embodiment Construction

[0015] refer to Figure 1 to Figure 5 , The cable support of the present invention is composed of a carrier frame 1 and several (at least one) transverse arms 2 . Carrying frame 1 is elongated component, and its front lower end has the protrusion 14 of one band reinforcing rib 15, and there is a longitudinal reinforcing rib 13 in the middle of the back side, and both sides 16 become slide rail shape structure (such as figure 2 , Figure 5 shown); the expansion bolt 3 fastens the carrier frame 1 on the wall 4 through the mounting hole 11; the mounting hole 11 is oblong, which is beneficial to adjust the position of the carrier frame up, down, left, and right during installation, and the surrounding of the mounting hole 11 faces the back Protrude to at least the same height as the reinforcing rib 13 to form a raised platform 17, which is connected with a transverse reinforcing rib 12 to make the installation more secure. The cross arm 2 includes a unit cross arm 2a with only ...

Abstract

The cable rack consists of bearing frame and horizontal arms, which are sleeved onto the bearing frame and capable of sliding up and down and have notches to lay cable. The slide and cascade structure of the cable rack makes laid cable less likely to disconnect and the cable rack has high reliability, easy installation, cable-laying amount capable of being increased easily and small occupied space, so that the cable rack is suitable for use especially in underground engineering, expressway and other places with limited installation space.

Description

technical field [0001] The invention relates to a support for laying cables. Background technique [0002] Before the present invention was made, the supports for laying cables were classified by structure, and were usually divided into two categories: fixed (carrying frame and cross arm were fixed as one) and movable (cross arm can be separated from carrying frame). Regardless of the type of structure, there is a certain distance between the cross arms carrying cables on the same support, and this distance is generally a certain value (such as 60, 120, 180 mm, etc.). When laying the cable, after the cable is placed on the cross arm, fix it on the cross arm with clips or ropes. Due to the structural design and manufacturing process of the previous movable support, the cross arm often fell off under the action of external force, causing the laid cable to fall, and this type of support component could not bear the heavy weight of the cable (such as the commonly used in urban ...
