The advantage of such an arrangement is that, through the arrangement of the reset spring 18, the cross roller 15 can always play a squeezing effect on the electric pole when rotating, thereby improving the stability during lifting.

[0038] like Figure 8 As shown, the rotating mechanism includes a gear 23 and two semicircular racks 24. A through hole is opened on the top inner wall of the U-shaped rotating block 22. A rotating rod 25 is rotated in the through hole. The bottom end of the rotating rod 25 is rotatably installed on the bottom inner wall of the U-shaped rotating block 22. A first knob 26 is fixedly installed on the top of the rotating rod 25. The gear 23 is fixedly sleeved on the rotating rod 25. The two semicircular racks 24 are respectively fixedly arranged on the circumferential outer walls of the two semicircular shells 1. The gear 23 is adapted to the two semicircular racks 24. A damping washer 27 is fixedly sleeved on the rotating rod 25. The circumferential outer wall of the damping washer 27 fits with the circumferential inner wall of the through hole.

[0039] like Figure 8As shown, the sliding mechanism includes a screw rod 30, two ends of which are rotatably installed on the side of the U-shaped rotating block 22 and the side inner wall of the U-shaped frame 28, respectively; a movable plate 29 is threadedly installed on the screw rod 30, a limiting hole is provided on the side of the movable plate 29, a limiting rod 35 is slidably installed in the limiting hole, two ends of the limiting rod 35 are fixedly installed on the side of the U-shaped rotating block 22 and the side inner wall of the U-shaped frame 28, a round shaft 33 is rotatably installed on the side inner wall of the U-shaped frame 28, the other end of the round shaft 33 extends to the outside of the U-shaped frame 28 and is fixedly provided with a second knob 34, a worm 31 is fixedly sleeved on the round shaft 33, a worm wheel 32 is fixedly sleeved on the screw rod 30, and the worm 31 is meshingly installed with the worm wheel 32.

[0040] like Fig. 9 As shown, the adjustment mechanism includes two connecting rods 43, and rectangular grooves are provided on both sides of the movable plate 29.

The two connecting rods 43 are rotatably sleeved on the four fixed columns 42 respectively, and two of the fixed columns 42 are provided with stretching components.

[0041] like Fig.10 As shown, the reset assembly includes a slide rod 39, both ends of which are fixedly mounted on the inner walls of both sides of the rectangular groove, and the lifting block 40 is slidably mounted on the slide rod 39. An adjusting spring 41 is sleeved on the slide rod 39, and the adjusting spring 41 is sleeved on the slide rod 39. One end of the adjusting spring 41 is fixedly mounted on the bottom of the lifting block 40, and the other end of the adjusting spring 41 is fixedly mounted on the bottom inner wall of the rectangular groove. The advantage of this arrangement is that, through the setting of the adjusting spring 41, when the limit on the lifting block 40 is released, the lifting block 40 can be driven to achieve the reset function through its elastic action.

[0042] like Fig.10As shown, the stretching assembly includes two steel wire ropes 46, one ends of the two steel wire ropes 46 are respectively fixedly arranged on two of the fixed columns 42, a winding shaft 44 is rotatably installed on the inner wall of the side of the U-shaped frame 28, the other end of the winding shaft 44 extends to the outside of the U-shaped frame 28 and is fixedly arranged with a third knob 47, a winding roller 45 is fixedly sleeved on the winding shaft 44, the other ends of the two steel wire ropes 46 are respectively arranged on the two winding rollers 45, a limiting screw hole is provided on the top of the U-shaped frame 28, a limiting bolt 48 is installed in the inner thread of the limiting screw hole, and the limiting bolt 48 is adapted to the winding shaft 44. The advantage of such an arrangement is that, through the arrangement of the two winding rollers 45 and the two steel wire ropes 46, the lifting block 40 can be driven to realize the descending function by the winding of the steel wire rope 46, thereby realizing the angle adjustment of the rotating plate 37, and the adjustment operation is convenient, and the adjustment knobs are all in the same position, which is convenient for actual operation.

[0043] The working principle of the present invention is as follows: when performing emergency repair work on electricity, firstly, two semicircular shells 1 are sleeved on the electric poles, and then the two L-shaped plugs 8 that are adapted to each other are slid toward each other, the two compression springs 9 are squeezed, and then the two semicircular plates 7 are processed and plugged in, and then the limit of the L-shaped plugs 8 is released, and through the elastic action of the compression springs 9, multiple L-shaped plugs 8 are respectively engaged with multiple plug-in grooves 10, so that the two semicircular plates 7 and the two semi-annular bevel racks 6 are connected, and then the two semicircular shells 1 are fixed by multiple fixing bolts 3, so as to realize the assembly of the equipment, and the whole assembly operation is convenient and simple to operate.

[0044] Starting the adjusting motor 11 drives one of the screw guide sleeves 4 to rotate, and then drives the other three screw guide sleeves 4 to rotate synchronously under the meshing action of multiple bevel gears 5 and two semi-annular bevel racks 6, so that the four screws 12 and the four U-shaped blocks 13 are driven to move synchronously in the axial direction under the limiting action of multiple telescopic rods 14, so that the peripheral outer walls of the four cross rollers 15 are in contact with the peripheral outer walls of the poles. At this time, the four U-shaped blocks 13 continue to move, and the cross rollers 15 remain stationary due to the extrusion. At this time, multiple sliders 16 slide along the sliding holes and stretch multiple reset springs 18 until the multiple sliders 16 slide to the other side of the sliding holes. This arrangement can fix poles of different diameters, and the installation and fixing operation is simple and the stability is strong.

[0045] Start multiple drive motors 20 to drive multiple rotating shafts 19 and multiple cross rollers 15 to rotate synchronously. During the rotation of the cross roller 15, when the concave part contacts the outer wall of the peripheral side of the utility pole, the elastic action of the reset spring 18 makes the cross roller 15 always squeezed with the outer wall of the peripheral side of the utility pole, thereby effectively avoiding slipping. With this arrangement, the rotation of multiple cross rollers 15 can drive the equipment to automatically climb upward along the utility pole without the need for staff to carry it. Not only is the degree of stability high during lifting and lowering, but it also reduces the workload of staff and is highly practical.

[0046] During the lighting process, when it is necessary to adjust the lighting angle of the astigmatism lamp 36, the first knob 26 is rotated to drive the rotating rod 25 to rotate, and then the U-shaped rotating block 22 is driven to rotate under the meshing action of the gear 23 and the two semicircular racks 24, and then the U-shaped frame 28, the movable plate 29, and the astigmatism lamp 36 are driven to rotate synchronously, thereby realizing the angle adjustment function. When the position of the astigmatism lamp 36 is too close to affect the emergency repair operation or the position is too far to affect the lighting effect, the position of the astigmatism lamp 36 needs to be adjusted. At this time, the second knob 34 is rotated to drive the circular shaft 33 to rotate synchronously, and the meshing action of the worm 31 and the worm wheel 32 drives the lead screw 30 to realize the rotation function, and the movable plate 29 realizes horizontal movement through the thread action and the limiting function of the limit rod 35.

[0047] During the emergency repair process, sometimes it is necessary to provide centralized lighting for a certain position to facilitate observation by the staff. At this time, the spotlight 38 can be started to realize the lighting function of a certain position. When the illumination angle of the spotlight 38 needs to be adjusted, first release the limit bolt 48 on the winding shaft 44, and then rotate the third knob 47 counterclockwise to drive the two winding rollers 45 to rotate, thereby winding the two wire ropes 46. When the wire rope 46 is winding, the other end pulls the two fixed columns 42 and the two lifting blocks 40 to move downward, thereby driving the rotating plate 37 to realize the angle adjustment function under the connection action of the two connecting rods 43, thereby realizing the angle adjustment of the spotlight 38, and then rotate the limit bolt 48 to limit the winding shaft 44, thereby realizing the synchronous limit function of the rotating plate 37. After the limit bolt 48 on the winding shaft 44 is released, the lifting block 40 is driven to move upward by the elastic action of multiple adjustment springs 41, thereby driving the rotating plate 37 and the spotlight 38 to reset synchronously under the action of the two connecting rods 43.
