Description

Technical Field

[0001] The utility model relates to the technical field of cable trenches, in particular to a cable trench cable support which is convenient for cable installation. Background Art

[0002] The cable trench is an underground pipeline used for laying and replacing power or telecommunication cable facilities. It is also the enclosure structure of the laid cable facilities. There are rectangular, circular, arched and other pipeline structures. It is suitable for cable line paths with light ground loads, such as sidewalks, factory sites, etc. The cable trench cable bracket is a bracket inside the cable trench used to install and support cables. The cable trench cable bracket is usually made of angle steel profiles connected or spliced ​​by welding or fasteners. The traditional cable trench cable bracket has a simple structure, and the cable is prone to wear when dragged on the bracket. It does not have a clamping mechanism and has poor installation stability.

[0003] According to the search, the Chinese patent document, announcement number: CN219918266U, discloses a cable trench cable bracket that is convenient for cable installation. Through the installation of the cross bar, when the traction equipment pulls the cable on the cross bar, the cross bar is connected with the support rod through rotation, and the movement of the cable drives the cross bar to rotate relative to the support rod, thereby reducing the friction between the cable and the cross bar during the cable traction process; it not only reduces the wear on the cable during the cable traction process, but also after the cable is installed, the cross bar plays a supporting role for the cable, and it does not need to be removed, thereby improving the installation efficiency of the cable inside the cable trench. However, after the cable is placed, the cable trench cable bracket needs to manually install the pressure plates one by one on the bracket, which is very troublesome to operate and cannot quickly achieve the clamping and fixing of the cable.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] like Figure 1-6 As shown, the utility model provides a cable trench cable support which is convenient for cable installation, comprising a mounting seat 1, a support frame 2 is fixedly installed on the outer side of the mounting seat 1, a cavity 3 is opened inside the mounting seat 1, a connecting rod 4 is arranged inside the cavity 3, a slider 1 5 and a slider 2 6 are fixedly installed on the outer side of the connecting rod 4, a positioning screw 7 is threadedly installed on the outer side of the slider 2 6, a connecting block 8 is fixedly installed on the outer side of the slider 1 5, a slide groove 1 9 and a slide groove 2 10 are opened on the outer side of the mounting seat 1, a transmission roller 11 is rotatably installed on the outer side of the connecting block 8, connecting grooves 12 are opened on both sides of the support frame 2, a splint 13 is movably installed on the upper end of the support frame 2, a spring 14 is arranged inside the support frame 2, and an adjusting screw 15 is threadedly installed on the outer side of the support frame 2.

[0033] Specifically, the mounting base 1 has eight mounting holes 16 symmetrically arranged on both sides, and the support frame 2 has six equidistant mounting holes 16 arranged vertically, and the support frame 2 is a triangular structure. The advantage is that the mounting base 1 can be fixed to the inner wall of the cable trench by passing bolts through the mounting holes 16.

[0034] Specifically, two connecting rods 4 are provided, the second slider 6 is located above the first slider 5, and the positioning screw 7 passes through the second slide slot 10 and fits the outer side of the mounting seat 1. The advantage is that the positioning screw 7 is rotated outward to unlock the second slider 6, and the positioning screw 7 is moved up and down, and the connecting rod 4 slider 1 5 and the second slider 6 move accordingly. After moving to a suitable position, the positioning screw 7 is tightened to fix the second slider 6 by clamping.

[0035] Specifically, six sliders 5 are equidistantly arranged up and down, and the connecting block 8 is an "L"-shaped structure, and the connecting block 8 passes through the slide slot 9 and extends to the inside of the support frame 2. The advantage is that when the slider 5 moves, the transmission roller 11 is driven to move through the connecting block 8.

[0036] Specifically, the upper end of the support frame 2 is an open structure, and the transmission roller 11 extends to the upper side of the support frame 2. The advantage is that when the transmission roller 11 is located on the upper side of the support frame 2, the friction between the cable and the upper end of the support frame 2 is reduced, and the wear and tear caused by the cable when dragging is reduced.

[0037] Embodiment 2:

[0038] like Figure 1-6 As shown, as an improvement to the previous embodiment. Specifically, the clamping plate 13 passes through the connecting groove 12 and extends to the inside of the support frame 2. Eight clamping plates 13 are respectively provided at the upper end of the support frame 2, and seven springs 14 are respectively provided inside the support frame 2. Both ends of the spring 14 are fixedly connected to the clamping plates 13. The advantage is that the clamping plates 13 move horizontally at the upper end of the support frame 2 through the connecting groove 12, and the springs 14 apply elastic force to the clamping plates 13 on both sides, so that the distance between the eight clamping plates 13 remains consistent.

[0039] Specifically, the adjusting screw 15 is parallel to the driving roller 11, and the adjusting screw 15 is rotatably connected to the clamping plate 13. The advantage is that when the adjusting screw 15 is rotated, the clamping plate 13 at the most side is driven to move through the thread structure, and when the clamping plate 13 moves, the spring 14 is driven to contract, and the clamping plate 13 clamps and fixes the cable.

[0040] Working principle: First, use bolts to pass through the mounting holes 16 to fix the mounting base 1 on the inner wall of the cable trench. During the installation process, the cable is placed on the upper end of the support frame 2 and on both sides of the clamping plate 13. When the cable needs to be dragged, rotate the positioning screw 7 outward to unlock the slider 2 6, move the positioning screw 7 upward, and the connecting rod 4 slider 1 5 and slider 2 6 move accordingly. After moving to the top, tighten the positioning screw 7 to fix the slider 2 6 by clamping. At this time, the transmission roller 11 passes through the upper end of the support frame 2, and the cable moves along the transmission roller 11, reducing the friction between the cable and the upper end of the support frame 2. Friction can reduce the wear and tear of the cable when it is dragged. After the cable position is determined, the positioning screw 7 is moved downward to move the transmission roller 11 to the inside of the support frame 2, and then the adjusting screw 15 is rotated to drive the outermost clamping plate 13 to move through the threaded structure. When the clamping plate 13 moves, it drives the spring 14 to contract. The spring 14 applies elastic force to the clamping plates 13 on both sides to keep the distance between the eight clamping plates 13 consistent. When the clamping plates 13 contact both sides of the cable, the adjusting screw 15 is released. The clamping plates 13 clamp and fix the cable to prevent the cable from moving on the bracket, thereby improving the stability of the installation.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
