Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a cable corner support frame for power construction. Background Technology

[0002] In electrical construction, cable corner support frames are a key piece of equipment used to support and protect cables at corners. They ensure that cables maintain an appropriate bending radius when turning, preventing damage from excessive bending, while providing stable support to prevent sagging or displacement.

[0003] Existing cable corner support frames are typically used for cable wells or at corners within cable wells to support and deliver cables. These frames generally include rollers and brackets for mounting them. The brackets are placed on the already positioned cables below or on bricks to support cables not yet installed above. However, because the cables are unstable when being transported by the rollers, both the rollers and the cables move up and down, making this type of support unstable. This can easily cause the cables to detach from the rollers, affecting the normal transport of cables at corners and even causing the cables to get stuck at the corners of the cable well. Utility Model Content

[0004] To address the technical problems mentioned above, this utility model provides a cable corner support frame for power construction.

[0005] The technical solution of this utility model is as follows:

[0006] A cable corner support frame for power construction is installed in a rectangular cable well. It includes a first support frame and a second support frame that are vertically connected. The first support frame is vertically arranged, and the second support frame is horizontally arranged. At least one first roller is provided on the first support frame, and the axis of the first roller is vertically arranged. At least one second roller is provided on the second support frame, and the second roller is located on one side of the first roller. The axis of the second roller is horizontally arranged and perpendicular to the first roller.

[0007] A support frame is inclined on the side of the first support frame away from the second support frame. The support frame is telescopic and is connected to the inner wall of the cable well through a connector.

[0008] Preferably, there are two first rollers, which are arranged on both sides of the first support frame along the length direction.

[0009] Furthermore, the second roller is located between the two first rollers, and the axis of the second roller is higher than the lowest horizontal plane of the lower surface of the groove of the first roller.

[0010] When the cable passes through the first and second rollers, it generates thrust, causing the cable corner support frame to shift to one side. The cable well is generally a rectangular structure. The support frame is placed close to the inner wall of the adjacent cable well to counteract the thrust and reduce the overall movement of the cable corner support frame to one side. For this purpose, two support frames are provided, with their lengths perpendicular to each other, and each support frame is placed close to the inner wall of the adjacent cable well.

[0011] Furthermore, the angle between the support frame and the first support frame is 45°.

[0012] The specific structure of the aforementioned support frame is as follows: the support frame includes a rectangular tube and a support plate inserted inside the rectangular tube. The support plate is connected to the rectangular tube by fasteners, and a connector is located at one end of the outer side of the support plate.

[0013] Preferably, the lower surface of the second support frame is provided with support legs at all four corners, and the height of the support legs is adjustable.

[0014] The beneficial effects of this utility model are as follows:

[0015] Two parallel first rollers are positioned on the side of the first support frame closer to the second support frame and above the second support frame. The cable can move through the first and second rollers at the corner of the cable well, ensuring that the cable maintains an appropriate bending radius when turning and avoiding damage to the cable due to excessive bending. At the same time, the second rollers can provide stable support for the cable, preventing the cable from sagging or shifting, and at the same time, reducing wear on the cable surface.

[0016] The two support frames can be placed close to one corner of the cable well, which can counteract the thrust of the cable on the cable corner support frame as the cable moves, and prevent the cable corner support frame from shifting to one side, causing the cable to detach from the first and second rollers and affecting the movement of the cable. The support frame can be fixedly connected to the inner wall of the cable well through connectors, which can prevent the cable from detaching from the rollers and getting stuck.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cable corner support frame for power construction is installed in a rectangular cable well 10. It includes a first support frame 1 and a second support frame 2 connected vertically. The first support frame 1 and the second support frame 2 are rectangular frame structures. The first support frame 1 is set vertically, and the second support frame 2 is set horizontally. Two first rollers 3 are set on the first support frame 1. The two first rollers 3 are arranged on both sides of the first support frame 1 along the length direction, and the axis of the first rollers 3 is set vertically.

[0026] A second roller 4 is installed on the second support frame 2. The second roller 4 is located on one side of the first roller 3, with its axis horizontally positioned and perpendicular to the first roller 3. The second roller 4 is located in the lower part between the two first rollers 3, and its axis is positioned higher than the lowest horizontal plane of the lower surface 302 of the groove 301 of the first roller 3. The second roller 4 can support the cable and allows it to move smoothly on the second roller 4. The cable moves at an angle within the cable well 10, allowing it to contact the two first rollers 3 respectively, increasing the support points for the cable and enabling it to move at a suitable arc.

[0027] See Figure 2 and Figure 5As shown, a support frame 5 is inclined on the side of the first support frame 1 away from the second support frame 2. The support frame 5 is telescopic and is connected to the inner wall of the cable well 10 via a connector 6. The two support frames 5 can respectively abut against one corner of the cable well 10 and are connected to the inner wall of the cable well via connectors. This can counteract the thrust of the cable on the overall cable corner support frame when the cable moves, preventing the cable corner support frame from shifting to one side and causing the cable to detach from the first roller 3 and the second roller 4, thus affecting cable movement. The support frame 5 can be fixedly connected to the inner wall of the cable well 10 via connectors 6, preventing the cable from detaching from the rollers and getting stuck. The support frame 5 includes a rectangular tube 501 and a support plate 502 inserted into the rectangular tube 501. The support plate 502 is connected to the rectangular tube 501 via fasteners 8, and the connector 6 is located at one outer end of the support plate 502.

[0028] The rectangular tube 501 is horizontally positioned along its length. One end of the rectangular tube 501 is fixedly installed on one side of the first support frame 1, and the other end is inserted into the support plate 502. The fastener 8 is located on one side of the rectangular tube 501. A threaded hole communicating with the inside of the rectangular tube 501 is provided on one side of the rectangular tube 501. Both the fastener 8 and the connector 6 can be bolts. By tightening the fastener 8, one end of the fastener 8 can be pressed against the surface of the support plate 502, thereby limiting the position of the support plate 502.

[0029] When the cable passes through the first roller 3 and the second roller 4, a thrust is generated, causing the cable corner support frame to shift to one side. The cable well 10 is generally a rectangular structure. The support frame 5 is positioned close to the inner wall of the adjacent cable well 10 to counteract the thrust and reduce the overall movement of the cable corner support frame to one side. Therefore, two support frames 5 are provided, with their lengths perpendicular to each other, and each support frame 5 is positioned close to the inner wall of the adjacent cable well 10. Furthermore, the angle between the support frame 5 and the first support frame 1 is 45°.

[0030] The lower surface 302 of the second support frame 2 is provided with support legs at all four corners. The height of the support legs is adjustable. The support legs are existing technology and can be telescopic rods with locking function, which can be adaptively adjusted according to the height of the cables in the cable well 10.
