Description

Technical Field

[0001] This utility model belongs to the technical field of cable laying devices, and relates to a cable support, especially a temporary cable support for power engineering construction. Background Technology

[0002] During power engineering construction, it is often necessary to lay temporary power cables to supply power to electrical equipment. The common method for laying these temporary cables is to use temporary cable supports on the construction site. Existing temporary cable supports generally need to be set up in advance at the installation location, and are often laid manually one by one before the cable is pulled and placed onto the pre-installed temporary supports. However, cables have a certain weight, and workers often find it difficult to pull them straight, preventing them from drooping. When the distance between two temporary supports is large, the cable can easily drag on the ground, causing abrasion to the cable sheath during installation and potentially leading to leakage or electric shock.

[0003] Therefore, it is necessary to provide a temporary cable support that can reduce the labor intensity of workers while effectively preventing the cable from dragging on the ground and abrading the sheath. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary cable support for power engineering construction, so as to solve the technical problems in the prior art that it cannot provide timely support and protection for temporary cables laid by traction and that the cable sheath is easily worn.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A temporary cable support for power engineering construction includes a support body, a cable erection section, a traveling section, a linkage section, and a direction adjustment section. The cable erection section is located at the upper end of the support body, the traveling section is located at the lower end of the support body, and there are two or more support bodies. The direction adjustment section is located on the support body and has the freedom to rotate relative to the support body with the vertical direction of the support body as the axis. The linkage section is located between two adjacent support bodies, with one end hinged to the direction adjustment section and the other end hinged to the lower part of another support body.

[0007] The support body includes a support rod and support legs from top to bottom. The support rod is a vertical round rod, and the support legs are three or more and are evenly arranged around the support rod.

[0008] The support leg includes a fixed support leg and a swing support leg. The swing support leg is mounted on the lower end of the support rod via a hinge seat A and has the freedom to swing relative to the support rod. The fixed support leg is welded to the lower end of the support rod, and the walking part is fixed to the lower end of the support leg.

[0009] The direction adjustment part is fitted onto the support rod and is located between the cable erection part and the support leg.

[0010] The direction adjustment part includes a sliding sleeve with a hinge seat B. The sliding sleeve is fitted on the bracket body and has a clearance fit with the bracket body, and has the freedom to slide up and down relative to the bracket body and rotate around the bracket body. The linkage part includes a linkage rod. The front end of the linkage rod is hinged to the hinge seat B of the sliding sleeve on the previous bracket body, and the rear end is hinged to the lower part of the next bracket body.

[0011] The rear end of the linkage rod is hinged to the swing support leg on the rear bracket body.

[0012] The distance between the hinge axis of the swing support leg and the upper end of the swing support leg is D1, and the minimum distance between the hinge axis of the swing support leg and the side of the support rod is D2, where D1 > D2; the width of the hinge seat at the top of the swing support leg is W1, and the width of the support rod is W2, where W1 < W2.

[0013] The cable erection section includes an erection pole, mounting bases, and porcelain insulators. The erection pole is horizontally fixed to the top of a support pole. The mounting bases are fixed in pairs on the erection pole. The porcelain insulators are horizontally arranged between the pairs of mounting bases and have the freedom to rotate around their own axis. There are three porcelain insulators, which are evenly distributed along the length of the erection pole.

[0014] The walking part includes walking wheels, which are fixed to the lower end of the support body.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a temporary cable support for power engineering construction. By configuring the support as multiple support bodies connected by a linkage, in use, the end of the cable is passed from the cable mounting part on the rear support body to the cable mounting part on the front support body. Then, the cable is fixed to the front cable mounting part. Pulling the front cable support pulls the cable, and at the same time, the linkage gradually unfolds to its maximum unfolding angle, pulling the next support body. This continuously provides support for the unfolded cable during the cable pulling process, and so on, until the linkage at the front of the last support body is fully unfolded. In this way, effective support is provided for the cable during the laying of the cable and the pulling of the cable from one temporary installation support to the next, avoiding wear and tear on the cable sheath from dragging on the ground and reducing the labor intensity of workers.

[0016] In addition, this utility model also provides a direction adjustment part on the support body, which can adjust the pulling direction of the cable during the cable laying process, thereby meeting the usage requirements when the cable needs to be laid in a bend.

[0017] The technical solution provided by this utility model can provide real-time protection for cables during the installation process using a simple structure. It is easy to use, low in cost, and suitable for widespread application in the installation of temporary power cables during power construction. Attached Figure Description

Detailed Implementation

[0024] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0025] like Figures 1 to 5As shown, this utility model provides a temporary cable support for power engineering construction, which is used to support the cable and prevent it from dragging on the ground during the process of erecting the cable on the temporary cable support at the construction site. It includes a support body 1, a cable laying section 2, a traveling section 3, a linkage section, and a direction adjustment section. The cable laying section 2 is located at the upper end of the support body 1 and is used to place and support the cable. The traveling section 3 is located at the lower end of the support body 1 and is used to drive the support body 1 and the cable on it to travel. In order to provide effective support for the cable during the pulling process, the number of support bodies 1 needs to be two or more. In this embodiment, there are five. The direction adjustment section is located on the support body 1 and has the degree of freedom to rotate relative to the support body 1 with the vertical direction of the support body 1 as the axis. It is used to provide steering for the previous support body 1 during the pulling process, so as to adapt to the requirements of cable turning settings on the construction site. The linkage section is located between two adjacent support bodies 1. One end is hinged to the direction adjustment section and the other end is hinged to the lower part of another support body 1. This setting can drive the support body 1 behind to move together when the foremost support body 1 is pulled. In addition, the linkage section and the direction adjustment section are used to increase the distance between two adjacent support bodies 1, thereby increasing the support length of the temporary cable support for the cable in this embodiment.

[0026] Specifically, in order to enable the support body 1 to provide cable support while maintaining stable movement, the support body 1 in this embodiment includes a support rod 101 and support legs from top to bottom. The support rod 101 is a vertical round rod, and the number of support legs is three or more, evenly arranged around the support rod 101. In this embodiment, there are three legs. Furthermore, in order to facilitate the storage of the temporary cable support in this embodiment after the temporary cable is erected, the support legs in this embodiment include a fixed support leg 102 and a swing support leg 103. The swing support leg 103 is set at the lower end of the support rod 101 through a hinge seat A104 and has the freedom to swing relative to the support rod 101. The fixed support leg 102 is welded to the lower end of the support rod 101. The walking part 3 includes a directional walking wheel 10 and a universal walking wheel 11. The directional walking wheel 10 is set at the lower end of the fixed support leg 102, and the universal walking wheel is set at the lower end of the swing support leg 103. When it needs to be stored, the swing support leg 103 is pushed to swing until it is parallel to the support rod 101, which reduces the footprint of the bracket body 1 and allows the bracket body 1 to be stored together; when the bracket needs to be unfolded, the swing support leg 103 opens to provide auxiliary support for the bracket body 1, thereby improving its stability during the pulling process.

[0027] Furthermore, such as Figure 1 , Figure 5As shown, the direction adjustment part is fitted onto the support rod 101 and located between the cable mounting part 2 and the support leg. Specifically, in this embodiment, the direction adjustment part includes a sliding sleeve 4 with a hinge seat B5. The sliding sleeve 4 is fitted onto the support rod 101 and has a clearance fit with the support rod 101, and has the freedom to slide up and down relative to the bracket body 1 and rotate around the support rod 101. The linkage part includes a linkage rod 6. The front end of the linkage rod 6 is hinged to the hinge seat B5 of the sliding sleeve 4 on the front bracket body 1, and the rear end is hinged to the swing support leg 103 at the bottom of the rear bracket body 1. This arrangement can push the sliding sleeve 4 to slide up and down relative to the support rod 101 during the relative retraction or opening of the two adjacent bracket bodies 1, reducing the footprint of the linkage rod 6 when it is stored. At the same time, the movement of the linkage rod 6 can also drive the swing support leg 103 on the rear bracket body 1 to retract or open relative to the support rod 101 to which it is hinged. Thus, when the front bracket body 1 pulls the rear bracket body 1 through the linkage rod 6, the swing support leg 103 on the rear bracket body 1 can be automatically opened, increasing the stability of the bracket body 1 during the movement.

[0028] Furthermore, to provide a limiting effect for the swing support leg 103, in this embodiment, the distance between the hinge axis of the swing support leg 103 and its upper end is set to D1, and the minimum distance between the hinge axis of the swing support leg 103 and the side of the support rod 101 is set to D2, where D1 > D2; the width of the hinge seat at the top of the swing support leg 103 is W1, and the width of the support rod 101 is W2, where W1 < W2. This setting allows the upper end of the swing support leg 103 to abut against the side of the support rod 101 after the swing support leg 103 is opened to a certain acute angle, thereby using the support rod 101 itself to provide a limiting effect for the swing support leg 103 and preventing the swing support leg 103 from failing.

[0029] Furthermore, in order to provide support and guidance for the cable, and at the same time reduce the friction of the cable during the traction process, such as Figure 5 As shown, the cable erection section 2 in this embodiment includes an erection rod 7, a mounting base 8, and a porcelain insulator 9. The erection rod 7 is horizontally fixed to the top of the support rod 101 and is perpendicular to the opening direction of the swing support leg 103. The mounting bases 8 are fixed in pairs on the erection rod 7. The porcelain insulators 9 are horizontally arranged between the pairs of mounting bases 8 and have the freedom to rotate around their own axis. There are 3 porcelain insulators 9, which are evenly distributed along the length of the erection rod 7.

[0030] When pulling cables, workers only need to pull the ends of two two-phase cables or three three-phase cables sequentially from the porcelain insulator 9 on the last support body 1 to the porcelain insulator 9 on the first support body 1. Then, the cables are sequentially fixed to different porcelain insulators 9 on the first support body 1. Next, the swing support leg 103 on the first support body 1 is opened, and the first support body 1 is pulled. This allows multiple cables to be pulled simultaneously towards the fixed temporary cable support, saving time and effort and increasing efficiency. Furthermore, the combined design of multiple support bodies 1 and linkage rods 6 effectively provides long-distance support for the cables, thus effectively preventing them from dragging on the ground during pulling and providing effective protection. Once pulled to the next fixed temporary cable support, the cables can be detached from the first support body 1 and fixed to the fixed temporary cable support.
