[0002] Electricity maintenance usually includes the maintenance and modification of wires and electrical equipment. Wires are an important part of power transmission and distribution. Common power failures include short circuits. Wire short circuits often occur in old wires. Wire short circuits refer to unexpected connections between two or more conductors in a wire, resulting in a sharp increase in current. When a wire short circuits, the core generates high temperature, which can cause multiple damage and aging of the wire sheath, greatly increasing the risk of leakage and short circuits in the future. Therefore, when repairing old wires, it is often necessary to replace the entire circuit and inspect the electrical equipment on the circuit to ensure the safety of electricity use in the future.

[0003] In the prior art, it is often necessary to use a stepladder to repair and replace wires and electrical equipment. Since most of the indoor wires are generally arranged on the wall in a direction parallel to the ground, most of the electrical equipment is also arranged along the direction of the wires. Therefore, when performing power maintenance, it is necessary to constantly move forward to adjust the position of the stepladder. Since maintenance personnel cannot move the stepladder forward on the stepladder to adjust the climbing position, maintenance personnel need to frequently go up and down the stepladder, resulting in low maintenance efficiency. Moreover, when the wires and electrical equipment are arranged at a high level, frequent going up and down the stepladder is inconvenient, labor-intensive, and has low operating safety.

By providing the upper ladder 14 and the lower ladder 11 on both sides of the base 1, it is convenient for maintenance personnel to climb onto the seat 15 from both sides, and it is also convenient to adjust the height of the seat 15. The utility model can adjust the climbing height and is suitable for power maintenance at different heights; and before climbing onto the seat 15, the lifting mechanism can be used to lower the seat 15, at which time the upper ladder 14 will slide downward on the upper side of the lower ladder 11 and remain connected, and after the maintenance personnel climb up through the upper ladder 14 and the lower ladder 11 and sit on the seat 15, the lifting mechanism is used to drive the seat 15 to rise to a suitable height, because the seat 15 is climbed at a relatively low height, the operation safety is high, and during maintenance, the maintenance worker sits astride the seat 15 for maintenance, and both feet can also step on the upper ladder 14 on both sides, so that the maintenance worker can sit stably and comfortably for maintenance operations;

[0023] A sleeve 16 is rotatably inserted on the seat 15, and a driving part is provided on the upper end of the sleeve 16, which can drive the sleeve to rotate on the seat 15. A sliding groove 9 is provided on the inner wall of the lower side of the sleeve 16, and a sliding rod 19 is slidably provided on the lower side of the sleeve 16. A slider 20 is provided on the outer wall of the slider 19, and the slider 20 is slidably arranged in the sliding groove 9. The slider 20 is slidably arranged in the sliding groove 9, and the slider 19 is rotatably inserted on the base 1, so that the sleeve 16 can slide on the slider 19, and the sleeve 16 can drive the slider 19 to rotate on the base 1. The lower end of the slider 19 is driven and connected to the wheel shaft 7 through a worm gear transmission mechanism. The rotation of the slider 19 can drive the wheel shaft 7 to rotate through the worm gear transmission mechanism, and when the slider 19 rotates forward, the wheel shaft 7 drives the roller 8 to move forward, and when the slider 19 rotates reversely, the wheel shaft 7 drives the roller 8 to retreat. It can move forward in the state of climbing to adjust the maintenance position, and does not need to go up and down frequently, which reduces the maintenance labor intensity and improves the safety of maintenance operations.

[0024] Preferably, the lifting mechanism includes a U-shaped frame 21 fixedly arranged in the middle of the upper surface of the base 1 and an internal threaded sleeve 18 fixedly arranged on the lower surface of the seat 15, a shaft rod 22 is rotatably arranged between the opposite side walls of the U-shaped frame 21, and the two ends of the shaft rod 22 are respectively transferred to the opposite side walls of the U-shaped frame 21, the shaft rod 22 is connected to a motor 25, and the motor 25 is fixed on the side wall of the U-shaped frame 21, the internal thread of the internal threaded sleeve 18 is connected to a screw rod 24, the lower end of the screw rod 24 is rotatably arranged on the top of the U-shaped frame 21, and a bevel gear 23 is provided on the lower end of the screw rod 24 and the shaft rod 22, and the two bevel gears 23 are meshed with each other. The motor 25 is used to drive the shaft 22 to rotate on the side wall of the U-shaped frame 21, and the shaft 22 drives the screw 24 to rotate on the top wall of the U-shaped frame 21 through the engagement of two bevel gears 23. Since the seat 15 and the internal threaded sleeve 18 cannot rotate with the screw 24, the positive and negative rotation of the screw 24 can drive the internal threaded sleeve 18 to rise and fall, thereby adjusting the height of the seat 15.

[0025] Preferably, a slide bar 19 is rotatably inserted into the top of a U-shaped frame 21, internal threaded sleeves 18 are fixedly provided on both sides of the lower surface of the seat 15, bevel gears 23 are provided on both sides of an axle rod 22, and there are two screw rods 24, which are respectively located on both sides of the slide bar 19. The seat 15 is driven to rise and fall together by arranging two internal threaded sleeves 18 and two screw rods 24, so that the overall structure is evenly stressed during the lifting process.

[0026] Preferably, sleeve 2 13 is fixedly provided on the two upper side bars of the lower ladder 11, and slide bar 2 12 is fixedly provided at the bottom of the two side bars of the upper ladder 14. Slide bar 2 12 is slidably arranged in sleeve 2 13, so that when the upper ladder 14 is raised or lowered relative to the lower ladder 11, the lower end of the upper ladder 14 will swing on the upper surface of the base 1, and the upper end of the lower ladder 11 will swing on the lower surface of the seat 15, and at the same time, slide bar 2 12 slides in sleeve 2 13 to provide reasonable freedom of movement.

[0027] Preferably, the worm gear transmission mechanism includes a U-shaped frame 24 fixedly arranged on the lower surface of the base 1, and a shaft 25 is passed through the two side walls of the U-shaped frame 24 for common rotation, and a bevel gear 26 is fixedly arranged on the end of the shaft 25 and the wheel shaft 7, and the two bevel gears 26 are meshed with each other, and a worm wheel 3 is fixedly arranged on the shaft 25, and a worm 2 is fixedly connected to the lower end of the slide rod 19, and the lower end of the worm 2 is transferred to the bottom of the U-shaped frame 24, and the worm 2 is meshed with the worm wheel 3;

[0028] The slide bar 19 can be used to drive the worm 2 to rotate in the U-shaped frame 4. The worm 2 drives the shaft 5 to rotate on the two side walls of the U-shaped frame 4 through the worm wheel 3. The shaft 5 drives the front wheel axle 7 to rotate on the two wheel frames 10 through the two bevel gears 26, thereby driving the roller 8 to rotate. By utilizing the high transmission ratio of the worm wheel 3 and the worm 2, when a small driving force is input to the slide bar 19, the worm 2 can drive the shaft 5 to rotate through the worm 2, and can also realize the self-locking function, effectively avoiding the free rotation of the roller 8 and the movement of the base 1 when the slide bar 19 is not rotated, thereby reducing the operational safety of high-altitude power maintenance.

[0029] Preferably, the driving part is a handwheel 17 fixed to the upper end of the sleeve 16, and the handwheel 17 can drive the sleeve 16 to rotate on the seat 15. By rotating the sleeve 16, the forward movement distance can be accurately controlled, and with the cooperation of the worm gear 3 and the worm 2, the input force of rotating the handwheel 17 can be reduced.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
