Technical Field

[0001] The utility model relates to the technical field of cable supports, and in particular to a cable support used in a transformer substation. Background Art

[0002] Substation cable rack is a device used to support, fix and protect cables. It is commonly used in substations and power transmission lines. The cable rack provides a supporting structure to suspend the cables in the air or on the ground to ensure that the cables remain in a stable position during operation. The cable rack can ensure that the cables are properly fixed to prevent them from shaking or being damaged in extreme weather conditions such as wind and rain.

[0003] Patent publication number "CN218335144U" discloses "an assembled substation cable support, comprising a support body, a support frame rotatably arranged on the support body, a limit plate fixedly arranged on the support frame, a recovery mechanism for storing the support frame is arranged between the limit plate and the support body, an extension plate is slidably arranged in the support frame, a plurality of telescopic rods are slidably arranged in the extension plate, two clamping rings are fixedly arranged on the plurality of telescopic rods, a spring is fixedly arranged between the two clamping rings, a plurality of circular holes are opened on the support frame, and the recovery function of the support frame is realized by arranging the support frame, the rotating shaft one and the rotating shaft two, and the support frame can be folded up when not working, and the extension plate is arranged inside the support frame, so that when a large number of cables need to be supported, the length of the support frame can be adjusted, so as to fully support them, thereby solving the problem that the existing support device cannot adjust the support frame."

[0004] Although the existing cable brackets used in substations are convenient for adjusting the length of the support frame, they cannot fix the surface of the cable, which may cause the cable to shake under the action of external force, and may cause the cable to separate from the bracket, increasing the risk of cable damage. Therefore, there is a problem of inconvenience in limiting the cable. Utility Model Content

The spring rebounds and drives the sliding frame to slide downward along the outer surface of the limiting column, so that the multiple groups of first rollers and the multiple groups of second rollers can clamp the outer surface of the cable. On the one hand, when the cable is pulled, the friction between the cable and the fixed frame and the sliding frame is reduced, which makes it easier to pull the cable and slide between the fixed frame and the sliding frame. On the other hand, it is easy to limit the outer surface of the cable to prevent the cable from sliding left and right significantly.

[0022] 2. Slide the sliding block into the inner side of the mounting frame, slide it to the appropriate position and then turn the knob. The knob drives the two-way threaded rod to rotate.

[0032] Specifically, the outer surface of the sliding frame 202 is slidingly connected to the limiting column 205, the lower surface of the limiting column 205 is fixedly connected to the upper surface of the sliding plate 207, and the upper surface of the limiting column 205 is fixedly connected to the limiting plate 203, the lower surface of the limiting plate 203 is fixedly connected with a spring 204, and the other end of the spring 204 is fixedly connected to the upper surface of the sliding frame 202, wherein the outer surface of the sliding plate 207 is threadedly connected with a fixing bolt 206, the lower end of the fixing bolt 206 is threadedly connected to the upper surface of the support plate 307, and the upper surface of the support plate 307 is provided with multiple groups of threaded holes.

[0033] The outer surface of the sliding frame 202 is further pulled up to compress the spring 204, and then one end of the cable is passed through between the fixed frame 201 and the sliding frame 202. Then the sliding frame 202 is released, and the spring 204 rebounds to drive the sliding frame 202 to slide downward along the outer surface of the limiting column 205, so that the multiple groups of first rollers 208 and the multiple groups of second rollers 209 can clamp the outer surface of the cable. On the one hand, when the cable is pulled, the friction between the cable and the fixed frame 201 and the sliding frame 202 is reduced, which makes it easier to pull the cable and slide between the fixed frame 201 and the sliding frame 202. On the other hand, it is easy to limit the outer surface of the cable to prevent the cable from sliding left and right significantly.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment.

The spring 204 rebounds and drives the sliding frame 202 to slide downward along the outer surface of the limiting column 205, so that the multiple groups of first rollers 208 and the multiple groups of second rollers 209 can clamp the outer surface of the cable.
