Description

Technical Field

[0001] This utility model relates to the field of cable support structure technology, and in particular to a cable trench roller-type cable support device. Background Technology

[0002] The installation of cable-bearing structures in cable trenches is a crucial step in the laying of power and communication pipelines. Through rigid or rolling supports, the cable-bearing structures distribute the cable's own weight and external loads, preventing problems such as long-term stress cracking of the insulation layer and separation of joints caused by the cable sags.

[0003] In the prior art, a search revealed a Chinese patent entitled "A Cable Trench Rolling Cable Carrying Device," application number "202320401686.X." This patent mainly includes a bracket, several crossbars, several rollers, and several outer protective wheels. The crossbars are horizontally spaced along the vertical direction on the bracket. The rollers are fitted onto the crossbars and are evenly spaced. The outer protective wheels are vertically installed on both sides of each roller in the horizontal direction and connected between adjacent crossbars. After installation, the outer protective wheels and rollers form a grid structure, with two adjacent rollers (upper and lower) and two adjacent outer protective wheels (left and right) forming a grid point. While this patent effectively separates cables through a grid structure and uses rollers to allow cables to be smoothly dragged on the bracket without damage, the integrated bracket with multiple rollers carrying cables makes it difficult to flexibly handle construction environments with varying cable trench dimensions (such as different widths or heights). For example, cable trenches with limited width may not be suitable for installation, and cable trenches with insufficient height may hinder installation due to excessive vertical space occupied by the supports. Therefore, this invention provides a roller-type cable support device for cable trenches to solve the problems mentioned in the background art. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 The present invention relates to a cable trench roller-type cable support device, which includes multiple independently set fixing plates 7. Each fixing plate 7 has multiple independently set mounting frames 1 on one side. The fixing plates 7 are connected to the cable trench wall by second bolts 8. Each mounting frame 1 has a roller support assembly on its inner side. Each mounting frame 1 has a connecting plate 4 fixedly fixed at equal intervals on its outer side. Each pair of adjacent connecting plates 4 are detachably connected by first bolts 5 and nuts. The mounting frame 1 closest to the fixing plate 7 is fixedly connected to the fixing plate 7.

[0025] A connecting plate 4 is provided on the outer side of the mounting frame 1 to connect with the connecting plate 4 of another mounting frame 1. The connection is made by fastening the first bolt 5 and nut, realizing modular and rapid assembly. At the same time, the independent structure between the fixing plates 7 allows for the installation of different numbers of fixing plates 7 according to usage requirements, thereby adjusting the number of mounting frames 1 according to actual cable support requirements and the size of the cable trench.

[0026] Because the fixing plate 7 and the mounting frame 1 adopt an independent structural design, users can freely adjust the number of mounting frames 1 according to the actual cable support requirements and the width and height of the cable trench, avoiding the problem that traditional integral brackets cannot adapt to changing construction environments. For example, the number of mounting frames 1 can be reduced in cable trench sections with narrow widths, while the number of fixing plates 7 can be reduced in cable trenches with narrow heights, and flexible expansion helps to improve construction efficiency.

[0027] The roller support assembly includes three mounting plates 2 fixed inside the mounting frame 1 and rollers 3 rotating inside the mounting plates 2. The center of each roller 3 is recessed, and the mounting plates 2 are all U-shaped and together form a triangular structure.

[0028] The structure consists of three U-shaped mounting plates 2 forming a triangular support structure. The rollers 3 rotating inside the mounting plates 2 can serve as guides and supports to facilitate the support and guidance of the cable. The concave structure of the rollers 3 makes the cable more stable with the lower limit located between the rollers 3.

[0029] Each fixing plate 7 has an extension 13 at its top and a groove 12 at its bottom. The extension 13 can be inserted into the adjacent groove 12. When installing the fixing plates 7 according to the number of fixing plates used, the extension 13 of the fixing plate 7 is connected to the groove 12, which makes the connection between adjacent fixing plates 7 more stable.

[0030] The mounting frame 1, which is far from the fixed plate 7, is symmetrically provided with diagonal fixing components. The diagonal fixing components include a diagonal rod 9 located at the top of the mounting frame 1, a movable plate 11 that rotates at one end of the diagonal rod 9 near the fixed plate 7, a third bolt 10 inserted at the other end of the diagonal rod 9, and a threaded groove 6 opened on the top side of the mounting frame 1. The third bolt 10 is connected to the threaded groove 6.

[0031] One end of the diagonal tie rod 9 is connected to the cable trench wall via a movable plate 11, and the other end is screwed into the threaded groove 6 on the top of the mounting frame 1 via a third bolt 10, forming a stable triangular tie structure, which is beneficial for improving the lateral tensile load-bearing capacity of the lifting device. Threaded grooves 6 are also provided on the top of the mounting frame 1 to cooperate with the diagonal tie rod 9, and one end of the diagonal tie rod 9 is movably connected to the movable plate 11. By changing the inclination angle of the diagonal tie rod 9, it can be connected to the corresponding mounting frames 1 according to the number of mounting frames 1 to be installed.

[0032] The mounting frame 1, mounting plate 2, connecting plate 4, fixing plate 7, movable plate 11, and diagonal tie rod 9 are all coated with galvanized steel to improve durability in underground environments. Rollers 3 are made of insulating material to enhance insulation.

[0033] Working principle: A connecting plate 4 is set on the outside of the mounting frame 1 and connects to the connecting plate 4 of another mounting frame 1. The connection is fastened by the first bolt 5 and nut, realizing modular and rapid assembly. At the same time, the independent structure between the fixing plates 7 allows for the installation of different numbers of fixing plates 7 according to usage requirements, so that the number of mounting frames 1 can be adjusted according to the actual cable support requirements and the size of the cable trench.

[0034] The cable is inserted between the rollers 3, and a triangular support structure is formed by three U-shaped mounting plates 2. The rollers 3 rotating inside the mounting plates 2 can play a guiding and supporting role, so as to support and guide the cable. The concave structure of the rollers 3 makes the cable more stable with the lower limit located between the rollers 3.

[0035] Then, one end of the diagonal tie rod 9 is connected to the wall of the cable trench through the movable plate 11, and the other end is screwed into the threaded groove 6 at the top of the mounting frame 1 through the third bolt 10, forming a stable triangular tie structure, which is beneficial to improving the lateral tensile load bearing capacity of the device.

[0036] Because the fixing plate 7 and the mounting frame 1 adopt an independent structural design, users can freely adjust the number of mounting frames 1 according to the actual cable support requirements and the width and height of the cable trench, avoiding the problem that traditional integral brackets cannot adapt to changing construction environments. For example, the number of mounting frames 1 can be reduced in cable trench sections with narrow widths, while the number of fixing plates 7 can be reduced in cable trenches with narrow heights, and flexible expansion helps to improve construction efficiency.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
