Description

Technical Field

[0001] This utility model relates to the field of cable laying, specifically to cable laying supports. Background Technology

[0002] During cable laying, one end of the cable needs to be connected to the power station. If the cable diameter is large or the number of cables is large, conventional concrete covering can no longer meet the safety requirements of laying. Therefore, a special laying tunnel will be built for the cable laying to ensure the concentration of cable laying, safety of use and convenience of maintenance.

[0003] To ensure that cables are laid neatly and in a standardized manner in tunnels and to avoid cable overlap, supports are erected in the tunnels, and then cables are placed on the supports. The traditional method is to first pull the cable in the tunnel before placing it on the supports. After the cable is pulled, it is then lifted onto the cable supports. This lifting process requires lifting equipment to lift the cable section by section, and the narrow space of the tunnel greatly increases the difficulty of lifting. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cable laying support that allows the cable to be directly pulled on the support, thereby reducing the need for cable lifting operations in tunnels.

[0005] The technical solution adopted by this utility model to solve the above problems is a cable laying bracket, including a support frame. The support frame is designed to be horizontally fixed. The upper end of the support frame is provided with two ball bearings arranged along the length direction of the support frame. The distance between the two ball bearings is less than the diameter of the cable to be laid.

[0006] Compared with the prior art, the advantages of this utility model are as follows: two ball bearings are directly set on the support, and the distance between the two ball bearings is less than the diameter of the cable to be laid, which ensures the support and counteracting effect of the two ball bearings on the cable. Then, the rotation function of the ball bearings is used to directly pull the cable on the support frame. In this way, only one lifting is required when the cable enters the tunnel. The subsequent pulling process can always keep the cable on the support frame, reducing the lifting operation in the whole tunnel, having less impact from the terrain, and reducing the lifting difficulty.

[0007] As an improvement of this utility model, the upper end of the support frame is also provided with two right-angled wedge blocks, the inclined surfaces of the two right-angled wedge blocks are arranged opposite each other, and the two balls are respectively arranged on the inclined surfaces of the two right-angled wedge blocks. Through this improvement, the cable can be prevented from detaching from the support of the balls during the traction process, and the traction correction function can be provided, so that the cable is always restricted between the two right-angled wedge blocks and the support of the balls for the cable can be guaranteed.

[0008] As an improvement of this utility model, a ball groove is provided on the inclined surface of the right-angled wedge block, and the ball is rolled and connected in the ball groove. The depth of the ball groove is greater than the radius of the ball and less than the diameter of the ball. Through this improvement, the ball is installed. The depth of the ball groove being greater than the radius of the ball ensures the stability of the ball installation and effectively prevents the ball from detaching from the ball groove. The depth of the ball groove being less than the diameter of the ball ensures the ball protrudes on the inclined surface, thereby ensuring the abutment effect between the cable and the ball, ensuring the rolling connection during traction, and avoiding cable wear during traction.

[0009] As an improvement of this utility model, each of the right-angled wedge blocks is provided with multiple balls on its inclined surface. The multiple balls are arranged along the same horizontal plane. Through this improvement, the support stability of the balls for the cable is enhanced.

[0010] As an improvement of this utility model, one end of the support frame is fixedly connected to the wall, and a reinforcing frame is fixedly connected to the lower end of the end of the support frame that is fixed to the wall. Through this improvement, the fixing strength of the support frame is strengthened, and damage to the support frame is avoided during long-term support.

[0011] As an improvement of this utility model, the center of gravity of the cable is located in the area directly above the reinforcing frame. Through this improvement, the reinforcing effect of the reinforcing frame on supporting the cable is enhanced, thereby reducing the supporting load of the support frame and ensuring the service life of the support frame.

[0012] As an improvement of this utility model, multiple support frames are provided in the same longitudinal plane, thereby enabling the laying of a greater number of cables in the tunnel.

[0013] As an improvement of this utility model, in the same longitudinal plane, a support rod is connected between two adjacent support frames, and a support rod is also provided between the lowest support frame and the ground. The support rod is located at the end of the support frame away from the wall. Through this improvement, the support stability of the support frame is ensured by the design of the support rod.

[0014] As an improvement of this utility model, the support rod and the support frame are detachably connected. With this improvement, when the cable needs maintenance, it is easy to detach the cable from the support frame, thereby increasing the maintenance space for the cable and reducing the difficulty of maintenance.

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, a cable laying bracket includes a support frame 1, which is horizontally fixed and made of square tubular steel. The upper end of the support frame 1 is provided with two ball bearings 2 arranged along the length of the support frame 1. The distance between the two ball bearings 2 is less than the diameter of the cable 6 to be laid. The upper end of the support frame 1 is also provided with two right-angled wedge blocks 3, the inclined surfaces of the two right-angled wedge blocks 3 are arranged opposite each other, and the two ball bearings 2 are respectively arranged on the inclined surfaces of the two right-angled wedge blocks 3.

[0021] like Figure 2 , Figure 3 As shown, the inclined surface of the right-angled wedge block 3 is provided with a ball groove 3.1, and the ball 2 is tumblingly connected in the ball groove 3.1. The depth of the ball groove 3.1 is greater than the radius of the ball 2 and less than the diameter of the ball 2. Each right-angled wedge block 3 has multiple balls 2 on its inclined surface, and the multiple balls 2 are arranged along the same horizontal plane. Fixing holes are provided on the outer sides of both ends of the multiple balls 2. The fixing holes are used to fix the right-angled wedge block 3 to the support frame 1 by fastening bolts. During the traction process, friction between the cable 6 and the right-angled wedge block 3 is inevitable. To avoid wear on the cable 6, the right-angled wedge block 3 is made of wood. In order to ensure the smooth rotation of the metal balls 2 in the right-angled wedge block 3, a metal ball sleeve 2.1 is provided between the ball 2 and the right-angled wedge block 3. The ball sleeve 2.1 is embedded in the ball groove 3.1 for fixed connection, and the ball 2 is tumblingly connected in the ball sleeve 2.1.

[0022] like Figure 1 As shown, one end of the support frame 1 is fixedly connected to the wall, and a reinforcing frame 4 is fixedly connected to the lower end of the support frame 1 that is fixed to the wall. The center of gravity of the cable 6 is located in the area directly above the reinforcing frame 4.

[0023] In the same longitudinal plane, there are multiple support frames 1. In the same longitudinal plane, there is a support rod 5 connecting two adjacent support frames 1. The lowest support frame 1 is also provided with a support rod 5 between it and the ground. The support rod 5 is located at the end of the support frame 1 away from the wall. The support rod 5 is detachably connected to the support frame 1.

[0024] In a tunnel, for the installation of a single cable 6, a support frame 1 is installed every 3-5 meters. A traction steel bar is then used to sequentially pass over several support frames 1 along the tunnel's direction from the tunnel's end until it reaches the tunnel's beginning and is fixedly connected to the cable 6. The traction steel bar is then retracted, moving the cable 6 from the tunnel's beginning to the end above the support frames 1, thus completing the installation of the cable 6 on the support frames 1. For cables 6 directly buried on the ground, a traditional traction method can be used, placing a transport trolley beneath the cable 6 to complete its installation in the tunnel.

[0025] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
