Description

Technical Field

[0001] The invention relates to the field of electric power maintenance, in particular to a single-conductor passenger electric pulley device. Background Art

[0002] Overhead transmission lines operate in open-air environments, facing the challenges of harsh natural environments and inclement weather. These issues often lead to problems such as missing, rusted, and aged cotter pins and hardware, falling or shifting anti-vibration hammers, and foreign objects hanging on the conductors. Therefore, regular comprehensive line maintenance is particularly important.

[0003] During daily maintenance work, workers are required to move along the conductors. The mobile pulley used is as described in the application number "201921861108.4", including a ladder head for carrying workers and lifting pulleys symmetrically arranged on both sides of the ladder head frame, and the workers move along the conductors through the pulley structure. Due to the non-fixed position of the work point, the workers need to manually pull the mobile pulley along the conductor to the target work point. Since the conductor is in an arc state under the action of gravity, it is prone to slippage when passing through a conductor section with a large inclination. Ground workers are also required to use a traction rope to assist in pulling the mobile pulley along the conductor. Due to terrain restrictions, the movement speed is slow, time-consuming, and work efficiency is low, so it needs to be solved urgently. Summary of the Invention

[0004] To avoid and overcome the technical problems of the prior art, the present invention provides a single-conductor manned electric pulley device. The present invention can automatically and quickly drive operators along the conductor and adapt to terrains of varying inclinations, significantly improving maintenance efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A single-conductor passenger electric pulley device includes a traveling mechanism that moves along the conductor and a frame that moves synchronously with the traveling mechanism; the traveling mechanism includes a driving wheel and a driven wheel arranged on a support frame, and the wheel surface of the driving wheel and / or the driven wheel is provided with a wire groove along the circumferential direction for the conductor to be clamped and limited; the driving wheel and / or the driven wheel generate a vertical lifting action after being driven by a linear power source.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-2 In an embodiment of the present invention, a single-conductor manned electric pulley device includes a frame 1 for supporting an operator and a traveling mechanism 2 that can move along the conductor.

[0029] The traveling mechanism 2 includes a support frame 24, which is detachably fixed to the vehicle frame 1. In this embodiment, locating pins are mounted horizontally on both sides of the bottom of the support frame 24. Positioning holes are provided on both sides of the vehicle frame 1 for the locating pins to be inserted and positioned.

[0030] A driving wheel seat 23 is provided at the bottom of the support frame 24. The driving wheel seat 23 and the support frame 24 are slidably connected via a vertically arranged second guide post. A stop ring may be provided on the second guide post to limit the maximum sliding distance between the driving wheel seat 23 and the support frame 24. A second compression spring 232 is coaxially sleeved outside the second guide post, with its ends abutting the support frame 24 and the driving wheel seat 23, respectively. Four sets of second guide posts are preferably provided, arranged at the four corners of the bottom of the support frame 24.

[0031] A set of driving wheels 231 are mounted on the driving wheel seat 23. These are driven by a motor. A quick-swappable battery module 11 is mounted on the vehicle frame 1 to power the motors of the driving wheels 231. A throttle 12, preferably a Hall effect throttle, is also mounted on the vehicle frame 1 to control the motor speed of the driving wheels 231.

[0032] A sliding seat 25 is also mounted vertically on the support frame 24. A slide rail is provided on the sliding seat 25 in the vertical direction, and the adjustment seat 21 is slidably mounted on the rail. A driven wheel seat 22 is provided above the adjustment seat 21. The driven wheel seat 22 and the adjustment seat 21 are slidably connected via a vertically arranged first guide post. A limit ring may be provided on the first guide post to limit the maximum sliding distance between the driven wheel seat 22 and the adjustment seat 21. A first compression spring 211 is coaxially sleeved outside the first guide post. The two ends of the first compression spring 211 abut against the adjustment seat 21 and the driven wheel seat 22, respectively. Four first guide posts are preferably provided, arranged at the four corner ends of the top of the adjustment seat 21.

[0033] The driving wheel seat 23 is positioned above the conductor, while the driven wheel seat 22 is positioned below the conductor. The driven wheel seat 22 preferably includes two sets of driven wheels 221, symmetrically positioned on either side of the driving wheel 231. The surfaces of the driven wheels 221 and 231 preferably have circumferential grooves to allow the guide to engage within the grooves, preventing the conductor from slipping.

[0034] In order to facilitate the operator to adjust the position of the driven wheel seat 22, an adjusting screw rod 26 is also installed on the sliding seat 25. The adjusting screw rod 26 and the adjusting seat 21 form a screw slider. By adjusting the screw rod 26 to drive the adjusting seat 21 up or down, the distance between the driven wheel 221 and the driving wheel 231 is indirectly adjusted, so that the driven wheel 221 and the driving wheel 231 clamp the wire in place.
