Description

Technical Field

[0001] This utility model relates to the field of cable supports, and in particular to an adjustable cable trench support with an adjustable structure that can be adapted to installation in different trench widths. Background Technology

[0002] Cables are needed for high and low voltage transformation and power supply in the region, and they are usually laid in cable trenches. Cable trenches are underground pipes used to lay and replace power or telecommunications cables, and they are also the protective structure for laying cable facilities. Common types of cable trenches in substation projects include cable tunnels, above-ground cable trenches, and underground cable trenches.

[0003] Currently, cable supports are often custom-made according to the transverse dimensions of the cable trench. However, in actual construction, there are tolerances in the width of the cable trench, and errors can even occur along the length of the trench. These errors make it difficult to install standard support components, requiring a large amount of on-site cutting or correction, which is inefficient, has large errors, and affects the construction quality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cable trench bracket with adjustable crossbar width, which improves installation adaptability without increasing production complexity through structural improvements.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-width cable trench support includes a support, a horizontal bar, a vertical bar, a rolling sleeve, a roller, and a bracket. The horizontal bar has a hollow end with a connecting rod inserted inside. The connecting rod has an elongated hole. The hollow horizontal bar has mounting holes aligned with the elongated holes. The connecting rod is adjustablely locked to the horizontal bar using bolts, thereby adjusting the overall width of the support.

[0007] With the help of the rollers on the crossbar and the cable, rolling traction can be achieved, which is suitable for retrofitting laying requirements.

[0008] Furthermore, the bolt assembly includes a bolt and a nut, which, when tightened, can securely lock the connecting rod inside the crossbar.

[0009] Furthermore, the cable roller is rotatably mounted on a crossbar for supporting and pulling the cable.

[0010] Furthermore, the vertical rod is inserted between multiple horizontal rods to form a grid structure, thereby achieving zoned and limited positioning of the cable.

[0011] Furthermore, the bracket is installed on top of the cable trench support and is used to support the maintenance device for the cable.

[0012] Furthermore, the roller includes a steel sleeve, an insulating layer, and an outer protective layer, wherein the outer protective layer has a through hole and mud-blocking rubber rings are provided at the upper and lower ends of the through hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The adjustable crossbar length adapts to different trench width errors; reduces on-site modification workload and improves installation accuracy and efficiency; maintains the advantages of original cable layering and rolling laying; simple structure and easy to process and produce.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] Implementation, for example Figures 1 to 4 As shown, an adjustable-width cable trench support includes: a support 1, a horizontal bar 2, a vertical bar 3, a roller 4, and a sleeve 201. Both ends of the horizontal bar 2 are connected to the support 1, and the end of the horizontal bar 2 is a hollow sleeve 201, inside which a connecting rod 202 is inserted. The connecting rod 202 has an elongated hole 203. The sleeve 201 has a horizontal mounting hole corresponding to the elongated hole 203. The sleeve 201 and the connecting rod 202 are fixedly connected by bolt assemblies passing through the horizontal mounting hole and the elongated hole 203. By sliding the connecting rod 202, the lateral width of the cable trench support can be adjusted to adapt to the installation requirements of different cable trench widths.

[0022] Vertical rods 3 are inserted between multiple horizontal rods to form a grid structure, achieving zoned and limited cable movement. One end of bracket 5 is located at the top of the entire cable trench support, and the other end of bracket 5 is directly supported at the bottom of the cable trench, which can be used to support maintenance cables.

[0023] The cable roller 4 includes a steel sleeve 401, an insulating layer 402, and an outer sheath 403. The insulating layer 402 is fitted onto the steel sleeve 401, and the outer sheath 403 is fitted onto the insulating layer 402. The steel sleeve 401 is fitted onto the crossbar 2, and the diameter of the opening in the steel sleeve 401 is larger than the cross-sectional diameter of the crossbar 2, so that the steel sleeve 401 can ensure that the cable roller 4 can roll smoothly. Since the object it carries is a cable, insulation is very important. The outer sheath 403 is in contact with the cable, and the insulating layer 402 is placed between the outer sheath 403 and the steel sleeve 401 to effectively insulate against current leakage, preventing current from being transmitted through the steel sleeve 401 and causing a safety accident, thus improving the safety of the cable-bearing device.

[0024] The above-described embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any equivalent variations made based on the claims of the present utility model shall still fall within the scope of the present utility model.
