Description

Technical Field

[0001] This utility model relates to the field of cable supports, and in particular to a cable support with an adjustable structure that can adapt to cable trenches of different depths. 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, most cable supports are integral structures, requiring the cables to be installed before being placed into the cable trench. In actual installation, cable trench dimensions often have tolerances, and errors can even occur along the length of the trench. These errors make it difficult to install standard support components, especially when the cable trench is deep enough to prevent complete placement. This necessitates extensive on-site cutting or correction, resulting in low efficiency, large errors, and negatively impacting construction quality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a multi-layered cable trench support, 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] A multi-layered cable trench support includes a support frame, horizontal bars, vertical bars, cable rollers, and sleeves. The two ends of the horizontal bars are connected to the support frame. The support frame is assembled from multiple layers of interlocking panels, each with grooves and protrusions. Adjacent panels are connected by a mortise and tenon structure formed by the grooves and protrusions. The vertical bars are inserted between the horizontal bars to form a grid structure. Combined with the cable rollers on the horizontal bars, rolling traction of the cable is achieved, making it suitable for retrofitting cable laying requirements.

[0007] Furthermore, the splicing plate is provided with expansion screw holes for fixing the cable trench bracket to the side wall of the cable trench.

[0008] Furthermore, the cable roller is rotatably mounted on the crossbar for supporting and pulling the cable.

[0009] Furthermore, the roller includes a steel sleeve, an insulating layer, and an outer protective layer, the outer protective layer being provided with a mud-blocking rubber ring.

[0010] Furthermore, the bracket is located on top of the support and is used to support the maintenance cable inspection device.

[0011] 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.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] It supports layered and step-by-step installation, improving installation accuracy and efficiency; it retains the advantages of the original layered and rolling cable laying; and it has a simple structure that is easy to process and produce. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Implementation, for example Figures 1 to 7As shown, a multi-layered cable trench support includes: a support 1, a horizontal bar 2, a vertical bar 3, a roller 4, and a sleeve 201. The support 1 is composed of multiple splicing plates 101. The splicing plates 101 are provided with grooves 102 and protrusions 103. By connecting one splicing plate to another through a tenon and mortise structure formed by the groove 102 and the protrusion 103 aligned with another splicing plate, the required support height can be formed. The splicing plates 101 are also provided with mounting holes 105 for installing expansion screws, and a fixing hole 104 for connecting with the horizontal bar is provided in the middle. During installation, a single horizontal bar 2 and splicing plate 101 can be fixed as a prefabricated layer at the bottom of the cable trench 6, and then the layers are assembled one by one, which can adapt to cable trenches of different heights.

[0024] Both ends of the crossbar 2 are connected to the bracket 1, and the end of the crossbar 2 is a hollow sleeve 201, inside which a connecting rod 202 is inserted. The connecting rod 202 is provided with an elongated hole 203. The sleeve 201 is provided with 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 bracket can be adjusted to adapt to the installation requirements of different cable trench widths.

[0025] 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.

[0026] 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.

[0027] 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.
