[0003] When the existing wire rack is in use, the wires are installed on the wire rack mostly by fixing the wires with a fixing ring and a plurality of bolts. When it is necessary to maintain and service the cables at the connection between the wire rack and the fixing ring, it is necessary to remove the plurality of bolts, and then take out some cables in the fixing ring for maintenance and service. However, whether it is the process of removing or installing the wires in the wire rack, it is necessary to control a plurality of bolts. Since the bolts are small in size, they need to be specially stored, otherwise they are very easy to fall and lose. At this time, new bolts are required to fix the wires. This not only causes a waste of resources, but also makes it troublesome to install or remove the wires in the wire rack. Therefore, it is necessary to design a wire rack for power transmission engineering. Utility Model Content

During operation, by pulling the connecting rod 8 to move in the direction away from the fixing frame 3, the card block 11 is driven to gradually disengage from the slot 12, and the spring 10 is stretched until the card block 11 is completely disengaged from the slot 12, the pressure rod 6 can be rotated along the damping shaft 5 in the direction close to the fixing rod 1, until the pressure rod 6 is rotated to no longer block the placement slot 4, the wires located inside the placement slot 4 can be taken out, and some of the wires inside the placement slot 4 can be maintained and serviced. After completion, the wires are placed in the placement slot 4 again, and the pressure rod 6 is rotated in the opposite direction, so that the pressure rod 6 gradually enters the first rectangular slot 16. In this process, the card block 11 will gradually move in the direction away from the fixing frame 3 due to being blocked by the fixing frame 3, and drive the connecting rod 11 to move in the direction away from the fixing frame 3, and drive the connecting rod 11 to move in the direction close to the fixing frame 12, and drive the connecting rod 11 to move in the direction close to the fixing frame 12. The rod 8 moves and the spring 10 is stretched at the same time, until the pressure rod 6 is located in the first rectangular groove 16, and the block 11 moves to the corresponding position of the slot 12. At this time, under the action of the spring 10, the connecting rod 8 drives the block 11 to move in the direction of the slot 12 until the block 11 is completely inserted into the slot 12. At this time, with the cooperation of the block 11, the connecting rod 8 can be stably connected to the pressure rod 6, and then the pressure rod 6 can be stably pressed on the upper end of the fixing frame 3. At this time, the wire can be stably located in the placement groove 4, so that whether it is the way to install or remove the wires in the fixing frame 3, it is relatively simple, convenient and fast; using the overall equipment to support the wires can be applied in the field of power transmission engineering to transmit power.

[0023] Furthermore, the lower end of the pressure rod 6 is fixedly connected with a rubber pressure block 7. During operation, under the action of the rubber pressure block 7, the wire can be more stably located in the placement groove 4.

[0024] Furthermore, a sliding groove 13 is provided inside the pressure rod 6, and a sliding block 14 is slidably connected inside the sliding groove 13, and the sliding block 14 is fixedly connected to the clamping block 11. During operation, this not only allows the clamping block 11 to stably move inside the pressure rod 6, but also makes it difficult for the clamping block 11 to separate from the pressure rod 6.

[0025] Furthermore, an end face of the clamping block 11 away from the connecting rod 8 is provided with an inclined surface 15. During operation, when the pressing rod 6 is rotated in a direction away from the fixing rod 1, the connecting rod 8 and the clamping block 11 are driven to rotate. At this time, due to the existence of the inclined surface 15, although the clamping block 11 is blocked by the fixing frame 3, it will gradually move in a direction away from the fixing frame 3 and drive the connecting rod 8 to move, so that the pressing rod 6 can rotate smoothly and finally press on the upper end of the fixing frame 3.

[0026] Further, a plurality of evenly distributed climbing frames 2 are fixedly connected to the circumferential surface of the fixed rod 1. During operation, the existence of the climbing frames 2 facilitates the staff to climb up the fixed rod 1 to maintain the electric wires.

[0027] Furthermore, the plurality of sets of fixing frames 3 are distributed up and down, and the length of each set of fixing frames 3 increases from top to bottom, and the placement slots 4 on each set of fixing frames 3 are arranged in a stepped manner. When working, it is convenient to neatly arrange various wires in the overall device.

[0028] Furthermore, the locking assembly includes a threaded shaft 18, a fastening cap 19, a mounting seat 20, a mounting hole 21 and a mounting block 22. The front and rear ends of each fixing frame 3 are fixedly connected with the mounting seat 20, and the right end faces of multiple mounting seats 20 are provided with mounting holes 21. The circumferential surface of the fixing rod 1 is fixedly connected with the mounting block 22, and the end of the mounting block 22 away from the fixing rod 1 is fixedly connected with the threaded shaft 18. The circumferential surface of the threaded shaft 18 is threadedly connected with the fastening cap 19, and the mounting block 22 is connected to the mounting seat 20 through the mounting hole 21. During operation, when disassembling the fixing frame 3, it is necessary to first remove the fastening cap 19 from the threaded shaft 18, and then pull the fixing frame 3 along the mounting block 22 to move away from the fixing rod 1, so that the mounting seat 20 is gradually separated from the mounting block 22, and the disassembly operation of the fixing frame 3 is completed. When a new fixing frame 3 needs to be installed, the mounting seat 20 can be connected to the mounting block 22 under the action of the mounting hole 21, and a new fastening cap 19 can be replaced and threadedly installed on the circumferential surface of the threaded shaft 18, so that the fastening cap 19 is firmly connected to the threaded shaft 18, and the fastening cap 19 is in close contact with the mounting seat 20 and the mounting block 22 to ensure that the fixing frame 3 is stably connected to the fixing rod 1, and then the fixing frame 3 can be used to support and fix the wires.
