Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and in particular to an easy-to-install power crossarm. Background Technology

[0002] In the field of power technology, cement power poles are one of the more common infrastructures. The upper end of the power pole is equipped with a crossarm, and the overhead power line is installed on the insulator fixed on the crossarm. Therefore, the crossarm plays an important role. However, nowadays, most power crossarms are integrated with the fixed structure, which means that when personnel replace the power crossarm, the entire device needs to be disassembled. This operation is not only inconvenient for personnel to work at height, but also reduces the safety of personnel when working.

[0003] A Chinese patent (authorization announcement number CN217975666U) describes a crossarm for electrical installation, which "includes a sleeve, two fixed rods, a crossbar, multiple teeth, multiple insulators, multiple fixed seats, multiple connecting blocks, a fixing assembly, and multiple sets of shock-absorbing assemblies. The two fixed rods are respectively fixedly connected to the crossbar, and the sleeve is disposed between the two fixed rods."

[0004] It is evident that the cited patent document has the problem that the entire device needs to be disassembled when it is replaced. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-install power crossarm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install power crossarm, comprising a crossarm mounting block, with slots on both sides of the mounting block, a rotating shaft longitudinally arranged in the inner cavity of each slot, a rotating rod transversely arranged in the inner cavity of each slot, bevel gears meshing with each other at one end of each rotating rod and around the periphery of each rotating shaft, a power crossarm body in the inner cavity of each slot, two locking blocks symmetrically welded around the periphery of each rotating rod, a through groove for the rotating rod to pass through on one side of each power crossarm body, grooves for the locking blocks to pass through symmetrically arranged on the inner sidewalls of each through groove, and locking slots for the locking blocks to perform circular motion on the inner sidewalls of each through groove.

[0007] Preferably, the top ends of both of the rotating shafts extend through to the top of the crossarm mounting block and are connected to a knob, and two connecting boxes are symmetrically installed on the top surface of the crossarm mounting block.

[0008] Preferably, each of the two connecting boxes has two springs connected to its inner top surface, and the free ends of each pair of springs are connected to a horizontal plate that passes through the connecting box.

[0009] Preferably, the bottom surfaces of the two horizontal plates are each equipped with a fitting block, and the top surfaces of the two knobs are provided with four fitting slots that engage with the fitting blocks at equal intervals.

[0010] Preferably, one side of the crossarm mounting block is welded with a mounting block for fitting around the perimeter of the utility pole, and one side of the mounting block is threadedly connected to a threaded shaft via a screw hole.

[0011] Preferably, one end of the threaded shaft is rotatably connected to an arc-shaped block for clamping the utility pole via a pin, and both sides of the mounting block are provided with sliding grooves.

[0012] Preferably, the inner walls of both grooves are welded with limit rods, and the two sides of the arc-shaped block are welded with sliders that are slidably sleeved around the limit rods.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This easy-to-install power crossarm allows for rotation of the shaft by turning a knob, which in turn rotates the lever to align the locking block with the groove. Then, pulling the power crossarm body allows for disassembly. Compared to existing devices that require separate disassembly and installation of the power crossarm, this device allows for individual disassembly and installation of the power crossarm body, avoiding the need to disassemble the fixing device along with the power crossarm body when replacing it.

[0015] By moving the horizontal plate, the mating block can be taken out of the mating slot or put into the mating slot, thereby fixing the position of the knob and preventing it from shifting due to external factors.

[0016] By rotating the threaded shaft, the movement of the arc-shaped block can be powered, thereby clamping it around the periphery of the utility pole. The sliding groove, limit rod, and slider can limit the movement of the arc-shaped block and prevent deviation. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The diagram shows an easy-to-install power crossarm, including a crossarm mounting block 1. One side of the mounting block 1 is welded with a mounting block 17 for fitting around the perimeter of a utility pole. One side of the mounting block 17 is threadedly connected to a threaded shaft 18 via a screw hole. One end of the threaded shaft 18 is rotatably connected to an arc-shaped block 19 for clamping the utility pole via a pin. The other end of the threaded shaft 18 is connected to a handle. The operator slides the mounting block 17 over the utility pole, positioning the pole between the inner wall of the mounting block 17 and the arc-shaped block 19. Turning the handle rotates the threaded shaft 18, causing the arc-shaped block 19 to move towards the utility pole, thus clamping the utility pole between the inner wall of the mounting block 17 and one side of the arc-shaped block 19, thereby securing it in place.

[0029] Both sides of the mounting block 17 are provided with sliding grooves 20. The inner walls of the two sliding grooves 20 are welded with limit rods 21. Both sides of the arc-shaped block 19 are welded with sliders 22 that slide around the limit rods 21. When the arc-shaped block 19 moves, it will drive the sliders 22 to move around the limit rods 21, which can limit the movement trajectory of the arc-shaped block 19 and prevent deviation.

[0030] Both sides of the crossarm mounting block 1 are provided with slots 2. The inner cavity of each slot 2 is provided with a rotating shaft 3 longitudinally. The bottom ends of the two rotating shafts 3 are rotatably connected to the inner bottom surface of the slot 2 through pins. The top ends of the two rotating shafts 3 extend through to the top of the crossarm mounting block 1 and are connected to a knob 11. The inner cavity of each slot 2 is provided with a rotating rod 4 laterally. One end of each rotating rod 4 and the periphery of each rotating shaft 3 are provided with meshing bevel gears 5. By rotating the knob 11, the operator can drive the rotating shaft 3 to rotate, so that the rotating shaft 3 drives one of the bevel gears 5 to rotate. Since the two bevel gears 5 are meshed with each other, when one bevel gear 5 rotates, it will drive the other bevel gear 5 to rotate, thereby driving the rotating rod 4 to rotate.

[0031] Both slots 2 have an electric crossarm body 6 inside. Two locking blocks 7 are symmetrically welded to the periphery of both rotating rods 4. One side of each electric crossarm body 6 has a through slot 8 for the rotating rod 4 to pass through. The inner walls of both through slots 8 have symmetrical grooves 9 for the locking blocks 7 to pass through. The inner walls of both through slots 8 also have slots 10 for the locking blocks 7 to move in a circular motion. Initially, the rotating rod 4 and locking blocks 7 are located in the cavities of the through slots 8 and 10, respectively, fixing the electric crossarm body 6. If disassembly is required, the operator rotates the knob 11, which, through the shaft 3, rotating rod 4, and two bevel gears 5, rotates the two locking blocks 7 90 degrees, aligning them with the two grooves 9. At this point, the operator pulls the electric crossarm body. 6. The rotating rod 4 and the locking block 7 can be removed from the inner cavity of the through groove 8 and the groove 9, thus realizing the separate disassembly of the power crossarm body 6. If installation is required, first align the positions of the two locking blocks 7 with the positions of the groove 9, and then insert the power crossarm body 6 into the empty groove 2 so that the rotating rod 4 can enter the through groove 8, while the two locking blocks 7 will pass through the groove 9 and enter the locking groove 10. At this time, turn the knob 11, and the two locking blocks 7 will be rotated 90 degrees through the rotating shaft 3, the rotating rod 4 and the two bevel gears 5, so that the positions of the two locking blocks 7 can be offset from the positions of the two grooves 9, thus fixing the power crossarm body 6. This avoids the situation that the fixing device needs to be disassembled together when replacing the power crossarm body 6, improving the safety of personnel when working at height.

[0032] Two connecting boxes 12 are symmetrically installed on the top surface of the crossarm mounting block 1. Two springs 13 are connected to the inner top surface of each connecting box 12. The free end of each pair of springs 13 is connected to a horizontal plate 14 that passes through the connecting box 12. A vertical groove is opened on one side of the connecting box 12 for the horizontal plate 14 to pass through. A handle that passes through the connecting box 12 is connected to the top surface of the horizontal plate 14. By pulling the handle, the horizontal plate 14 can be moved upward and the springs 13 can be squeezed. The springs 13 will deform after being pressed, which will buffer the force and achieve a damping effect. If the person releases the handle, the horizontal plate 14 can be moved downward by the rebound of the springs 13.

[0033] Both horizontal plates 14 have a locking block 15 installed on their bottom surfaces. The top surfaces of the two knobs 11 are equally spaced with four locking slots 16 that engage with the locking blocks 15. When the horizontal plate 14 moves upward, it will drive the locking block 15 to move upward, thereby removing it from the inside of the locking slot 16. This will release the fixing of the knob 11, allowing the knob 11 to rotate 90 degrees. After the knob 11 has rotated 90 degrees, the person releases the handle, and the spring 13 will cause the horizontal plate 14 to move downward, allowing the locking block 15 to enter another locking slot 16. This will fix the position of the knob 11 after rotation, preventing the knob 11 from shifting due to external factors.

[0034] Working principle:

[0035] This easy-to-install power crossarm involves slipping the mounting block 17 over the top of the utility pole and rotating the threaded shaft 18, which moves the arc-shaped block 19. This allows the inner walls of the arc-shaped block 19 and the mounting block 17 to clamp the utility pole, thus fixing the position of the power crossarm body 6. When the power crossarm body 6 needs to be replaced, the operator rotates the knob 11 90 degrees, which rotates the shaft 3 90 degrees. The shaft 3, through two meshing bevel gears 5, drives the rotating rod 4 to rotate 90 degrees, causing the rotating rod 4 to rotate the two locking blocks 7 90 degrees so that the two locking blocks 7 are aligned with the two grooves 9. At this point, the operator can pull the power crossarm body 6 to remove the rotating rod 4 and locking blocks 7 from the inner cavity of the through groove 8 and the groove 9, thus achieving separate disassembly of the power crossarm body 6. This avoids the need to disassemble the fixing device together when replacing the power crossarm body 6, improving the safety of personnel working at heights.
