[0024] See also Figures 1-8, a high-altitude power maintenance power tool anti-fall device, including a mounting frame 1, a driving mechanism 2 is provided on the mounting frame 1, and symmetrical upper rollers 4 and lower rollers 41 are provided on the upper and lower sides of the driving mechanism 2. The upper rollers 4 and the lower rollers 41 are rotatably arranged on the line, and the mounting frame 1 is also provided with a limiting mechanism 3 for limiting the driving mechanism 2. An openable baffle 5 is provided on the side of the upper roller 4 away from the driving mechanism 2. The mounting frame 1, the upper roller 4, the lower roller 41 and the baffle 5 wrap the line. A lifting mechanism 6 is provided below the lower roller 41, and a lifting rope 7 is connected to the lifting mechanism 6. The bottom of the lifting rope 7 is fixedly connected to the power maintenance tool box.

[0025] The present application adjusts the distance between the upper roller 4 and the lower roller 41 through the driving mechanism 2, so that the upper roller 4 and the lower roller 41 clamp the line, and the upper roller 4 and the lower roller 41 are rolled along the line through the moving device to realize the movement of the device. The bottom of the device is connected to the power maintenance tool box through the lifting rope 7. When working, the maintenance personnel only carry the device to climb. After climbing to the top of the tower, the device is fixed on the line, and then the power maintenance tool box is lifted to the line position through the lifting mechanism 6. Through this setting, there is no need for maintenance personnel to manually carry tools to climb and route the line, which reduces the burden on maintenance personnel and improves work efficiency.

[0026] A turntable 42 is rotatably installed at both ends of the upper roller 4 and the lower roller 41. An upper connecting block 43 is fixedly connected to one side of the upper turntable 42. A lower connecting block 44 is fixedly connected to the turntable 42 on the side of the lower end close to the baffle 5. A fixed handle 45 is fixedly installed on one side of the upper connecting block 43.

[0027] Under the action of the driving mechanism 2, the upper connecting block 43 and the lower connecting block 44 move simultaneously, driving the upper and lower turntables 42, the upper roller 4 and the lower roller 41 to move simultaneously, thereby clamping or loosening the line. After the upper roller 4 and the lower roller 41 clamp the line, the entire device can be driven to move along the line by moving the fixed handle 45, thereby reducing the burden on maintenance personnel in routing the line.

[0028] The driving mechanism 2 includes a bidirectional screw 22, which is rotatably installed in the mounting frame 1. A guide rod 21 is provided on one side of the bidirectional screw 22, and the guide rod 21 is fixedly installed in the mounting frame 1. The upper connecting block 43 is movably connected to the bidirectional screw 22 and the guide rod 21. A first worm gear 23 is fixedly provided in the middle part of the bidirectional screw 22, and a first worm 24 is meshedly connected to one side of the first worm gear 23. A rotating handle 25 is fixedly installed inside the first worm 24, and the rotating handle 25 is rotatably installed on the mounting frame 1.

[0029] The driving mechanism 2 is used to adjust the distance between the upper roller 4 and the lower roller 41. During adjustment, the first worm 24 and the first worm wheel 23 are driven to rotate by rotating the handle 25, and the first worm wheel 23 drives the bidirectional screw 22 to rotate, so that the upper roller 4 and the lower roller 41 are moved closer or farther away from each other, thereby adjusting the distance between the two and facilitating fixation or disassembly.

[0030] The limiting mechanism 3 includes a bevel gear 31, which is fixedly mounted on the rotating handle 25. The bevel gear 31 is meshed with a limiting tooth plate 32, and the limiting tooth plate 32 is fixedly mounted on the lower surface of the movable plate 33. The movable plate 33 is Z-shaped, and the upper surface of the lower end of the movable plate 33 is fixedly connected with a telescopic rod 36 and a first spring 37. The first spring 37 is mounted on the telescopic rod 36. The upper ends of the telescopic rod 36 and the first spring 37 are fixedly connected with a fixed block 35. The fixed block 35 is fixedly mounted on one side of the mounting frame 1. The upper surface of the upper end of the movable plate 33 is fixedly connected with a limiting rod 34, and the limiting rod 34 slides through the fixed block 35.

[0031] The limiting mechanism 3 is used to limit the upper roller 4 and the lower roller 41. The main action part is the rotating handle 25. The limiting tooth plate 32 presses the bevel gear 31 under the elastic force of the first spring 37 to prevent the bevel gear 31 and the rotating handle 25 from reversing, thereby ensuring the stability of the upper roller 4 and the lower roller 41. When the rotating handle 25 is operated in the forward direction, the limiting tooth plate 32 alternately engages with the teeth of the bevel gear 31. When the rotating handle 25 is operated in the reverse direction, the limiting tooth plate 32 engages with the teeth of the bevel gear 31 to prevent the rotating handle 25 from reversing.

[0032] The upper end of the baffle 5 is rotatably installed in the upper connecting block 43, and an adjusting slot 51 is opened at the lower end. A positioning assembly 52 is provided in the adjusting slot 51. The positioning assembly 52 includes a sliding frame 521. The sliding frame 521 is slidably connected to the adjusting slot 51 up and down. Both sides of the sliding frame 521 are slidably connected with baffles 522. The inner sides of the two baffles 522 are fixedly connected with second springs 524, and the outer sides are fixedly connected with insertion rods 523. The insertion rods 523 slide through both sides of the sliding frame 521 and are respectively inserted into the lower connecting block 44.

[0033] The upper end of the baffle 5 is rotatably installed in the upper connecting block 43 and can be rotated around the upper connecting block 43 to open or close. A positioning assembly 52 is set in the adjusting slot 51 at the lower end. The sliding frame 521 in the positioning assembly 52 can slide up and down in the adjusting slot 51. The baffle 522 is connected by a second spring 524, and the insertion rod 523 can be inserted into the lower connecting block 44 to fix the baffle 5. When it is necessary to open the baffle 5 to install or remove the device, pinch the baffle 522 to compress the second spring 524, so that the insertion rod 523 is pulled out from the lower connecting block 44, and the baffle 5 can be rotated to open. When closing, rotate the baffle 5 to the appropriate position, loosen the baffle 522, and the insertion rod 523 is inserted into the lower connecting block 44 under the action of the second spring 524 to fix the baffle 5. During the movement of the device, closing the baffle 5 can prevent the device and the power maintenance tool box from falling, thereby ensuring the safety of the tool during movement.

[0034] The lifting mechanism 6 includes a base frame 61, which is rotatably mounted on the lower end turntable 42. A fixing frame 66 is fixedly mounted inside the base frame 61, and an I-shaped pulley 65 is rotatably mounted on the fixing frame 66. The upper end of the lifting rope 7 is fixedly connected to the I-shaped pulley 65, and a second worm gear 67 is coaxially fixedly connected to one side of the I-shaped pulley 65. A second worm gear 68 is meshedly connected to one side of the second worm gear 67. A mounting box 62 is fixedly connected to the bottom of the base frame 61, and a battery 63 and a motor 64 are fixedly mounted inside the mounting box 62. The output end of the motor 64 is fixedly connected to the second worm gear 68. A switch 69 is fixedly mounted on the upper end of the mounting frame 1, and the battery 63, motor 64 and switch 69 are electrically connected.

[0035] The motor 64 in the installation box 62 is powered by the battery 63. The output end of the motor 64 drives the second worm 68 to rotate. The second worm 68 engages with the second worm wheel 67, and then drives the coaxial I-wheel 65 to rotate, thereby realizing the retraction and extension of the lifting rope 7, thereby lifting or lowering the power maintenance tool box.

[0036] With this arrangement, when maintenance personnel forget to bring or bring the wrong maintenance tools, they do not have to go down the tower and climb up again to replace them. By lowering the lifting rope 7, the ground staff can change to the corresponding tools and then automatically lift them to the top of the tower, which reduces the risk of maintenance personnel climbing repeatedly and alleviates their burden.

[0037] The working principle of this high-altitude power maintenance power tool anti-fall device: During high-altitude power maintenance operations, the power maintenance tool box is first fixedly connected to the bottom of the lifting rope 7. After the maintenance personnel climb to the top of the tower, they first install the device on the line, and by rotating the rotating handle 25 of the driving mechanism 2, adjust the distance between the upper roller 4 and the lower roller 41 to adapt to the thickness of the line. The limiting mechanism 3 then locks the roller distance, opens the baffle 5 to improve the stability of the connection between the device and the line, turns on the switch 69 of the lifting mechanism 6, and the motor 64 drives the I-wheel 65 to rotate. The lifting rope 7 lifts the tool box to the required position. When checking the wiring, the upper roller 4 and the lower roller 41 are rolled along the line through the fixed handle 45, driving the device and the tool box to move. The baffle 5 prevents the tools from falling, effectively solving the problems of inconvenient carrying and easy falling of tools and heavy burden on maintenance personnel in the traditional high-altitude power maintenance wiring process, thereby improving the safety and efficiency of the operation.
