Description

Technical Field

[0001] This utility model relates to the field of cable support technology, and more specifically, to a cable support for cable trenches. Background Technology

[0002] Cable trenches are underground pipes used for laying and replacing power or telecommunications cables. They also serve as the enclosure structure for the cables being laid. They come in various pipe structures, such as rectangular, circular, and arched. When laying cables in a cable trench, cable supports need to be installed on the side walls of the trench.

[0003] Currently, in the process of laying cables in cable trenches, the first step is to set up supports in the cable trench, and then lay the cables on the supports. However, the current cable supports are all cable angle steel supports. After installation, for some narrow cable trenches, the horizontal clearance of the supports will inevitably be too small, leaving insufficient safe operating space for cable laying personnel in the cable trench, which seriously hinders the work of the laying personnel. Therefore, this invention provides a cable support for cable trenches. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cable support for cable trenches, which solves the problem that after the cable support is installed, in some narrow cable trenches, the horizontal clearance of the support is too small, which leaves insufficient safe operating space for cable laying personnel in the cable trench, seriously hindering the operation of the laying personnel.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A cable support in a cable trench includes a base, a pair of connecting lugs fixedly connected to one side of the base, telescopic connecting assemblies rotatably connected to the outer circumferential surfaces of the pair of connecting lugs, a connecting plate fixedly connected to one side of the telescopic connecting assemblies, and a bracket fixedly connected to one side of the connecting plate.

[0009] A connecting block is fixedly connected to the side of the connecting plate away from the bracket. A slot is opened on the upper surface of the connecting block. A connecting block is fixedly connected to the side of the base near the connecting block. A pin is movably connected through the connecting block, and the lower end of the pin is engaged with the slot.

[0010] Furthermore, the telescopic connecting assembly includes a collar, lugs, a movable block, and a second limiting block. The collar is sleeved on the outer circumferential surface of the connecting lug. A pair of lugs are fixedly connected to the outer circumferential surface of the collar. Each pair of lugs has a through hole. A movable block is provided between the pair of lugs. The two sides of the movable block are fixedly connected to the second limiting block. One end of the second limiting block passes through the through hole, and one end of the movable block is fixed to the connecting plate.

[0011] Furthermore, one end of the bracket is curved upwards.

[0012] Furthermore, a stop block is fixedly connected to one side of the base, and the stop block is located above the pin.

[0013] Furthermore, a limiting block is fixedly connected to the outer circumferential surface of the collar.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution features a rotatable design for traditional angle steel brackets. After the base is installed on the side wall of the cable trench, the bracket can be rotated and placed against the side wall of the cable trench. After the bracket is placed against the side wall of the cable trench, the distance between the two opposing brackets will increase. Compared with the narrow cable trench, this can effectively improve the safe operating space for cable laying personnel and reduce the occurrence of collisions, scratches and other phenomena that hinder the construction of laying personnel.

[0017] (2) When laying cables, this solution rotates the support bracket to be perpendicular to the base, and then pushes the support bracket to one side of the base. During the pushing process, the pin will automatically engage with the connecting block installed on the back of the support bracket, thereby limiting the support bracket and ensuring the stability of the support bracket when supporting the cable. Moreover, the unfolding process of the support bracket is smooth and quick, which can effectively improve the efficiency of cable laying. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example

[0027] like Figure 1-5 As shown, a cable support in a cable trench includes a base 1, a pair of connecting lugs 2 fixedly connected to one side of the base 1, a telescopic connecting assembly 3 rotatably connected to the outer circumferential surface of the pair of connecting lugs 2, a connecting plate 4 fixedly connected to one side of the telescopic connecting assembly 3, and a bracket 5 fixedly connected to one side of the connecting plate 4.

[0028] A connecting block 6 is fixedly connected to the side of the connecting plate 4 away from the bracket 5. A slot 601 is opened on the upper surface of the connecting block 6. A connecting block 7 is fixedly connected to the side of the base 1 close to the connecting block 6. A pin 8 is movably connected through the connecting block 7. The lower end of the pin 8 is engaged with the slot 601.

[0029] When in use, after the base 1 is installed on the side wall of the cable trench, the bracket 5 can be rotated and placed against the side wall of the cable trench. After the bracket 5 is placed against the side wall of the cable trench, the distance between the two opposing brackets will increase. Compared with the narrow cable trench, this can effectively improve the safe operating space for cable laying personnel and reduce the occurrence of phenomena such as bumps and scratches that hinder the construction of laying personnel.

[0030] When laying cables, rotate the support bracket 5 to be perpendicular to the base 1, and then push the support bracket 5 to one side of the base 1. During the pushing process, the pin 8 will automatically engage with the connecting block 6 installed on the back of the support bracket 5, thereby limiting the position of the support bracket 5 and ensuring the stability of the support bracket 5 when supporting the cable. Moreover, the unfolding process of the support bracket 5 is smooth and quick, which can effectively improve the efficiency of cable laying.

[0031] like Figure 1-3As shown, the telescopic connecting assembly 3 includes a collar 301, lugs 302, a movable block 303, and a second limiting block 304. The collar 301 is sleeved on the outer circumferential surface of the connecting lug 2. A pair of lugs 302 are fixedly connected to the outer circumferential surface of the collar 301. Each pair of lugs 302 has a through hole 3021. A movable block 303 is provided between the pair of lugs 302. The second limiting block 304 is fixedly connected to both sides of the movable block 303. One end of the second limiting block 304 passes through the through hole 3021. One end of the movable block 303 is fixed to the connecting plate 4.

[0032] In use, after the pin 8 is pulled out of the slot 601, the bracket 5 can be stretched outward by one end under the connection of the telescopic connecting component 3. Then the bracket 5 can be rotated. During the rotation of the bracket 5, the connecting block 6 on the back is always in contact with the connecting block 7, but the slot 601 on the connecting block 6 and the pin 8 are misaligned. Therefore, the upper surface of the connecting block 6 always pushes up the pin 8. Therefore, when the connecting block 6 is reset, the slot 601 corresponds to the pin 8, and the pin 8 will automatically engage with the slot 601.

[0033] like Figure 1 As shown, one end of the bracket 5 is curved upwards.

[0034] When in use, the upward warping during cable laying can reduce the cable slipping off one end of the support 5.

[0035] like Figure 5 As shown, a stop 101 is fixedly connected to one side of the base 1, and the stop 101 is located above the pin 8.

[0036] When in use, the stop block 101 can limit the pin 8, so that the pin 8 can be bent out of the slot 601 without completely detaching from the connecting block 7, thus preventing the pin 8 from falling off or being lost.

[0037] like Figure 1 and 3 As shown in Figure 4, the outer circumferential surface of the collar 301 is fixedly connected to the limit block 3011.

[0038] During use, when the support 5 rotates to be perpendicular to the base 1 during the rotation and reset process, the limit block 3011 will contact the base 1 to prevent the support 5 from rotating excessively.

[0039] In summary, the specific working process of this solution is as follows: After the base 1 is installed on the side wall of the cable trench, the bracket 5 can be rotated and placed against the side wall of the cable trench. After the bracket 5 is placed against the side wall of the cable trench, the distance between the two opposing brackets will increase. Compared with the narrow cable trench, this can effectively improve the safe operating space for cable laying personnel and reduce the occurrence of phenomena such as bumps and scratches that hinder the construction of laying personnel.

[0040] During cable laying, the support bracket 5 is rotated to be perpendicular to the base 1, and then the support bracket 5 is pushed to one side of the base 1. During the pushing process, the pin 8 will automatically engage with the connecting block 6 installed on the back of the support bracket 5, thereby limiting the position of the support bracket 5 and ensuring the stability of the support bracket 5 when supporting the cable. Moreover, the unfolding process of the support bracket 5 is smooth and quick, which can effectively improve the efficiency of cable laying.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
