Description

Technical Field

[0001] This utility model belongs to the field of power engineering, specifically relating to a pole-climbing robot for cement utility poles. Background Technology

[0002] In the field of power engineering, State Grid construction workers mainly rely on traditional foot straps to climb concrete utility poles. These foot straps use the worker's own weight to maintain contact with the pole, and then use their feet to move up and down. Their advantages lie in their simple structure and low cost, making them a classic climbing tool in power construction.

[0003] However, this method has significant drawbacks: First, it is extremely physically demanding on construction workers, and prolonged work can easily lead to fatigue and increase safety risks; second, relying solely on manual climbing results in low work efficiency, especially when tools need to be carried or complex tasks are performed, further increasing the difficulty; third, the damping of traditional foot catches relies entirely on gravity, lacking additional safety mechanisms in certain special circumstances, such as worker errors or exhaustion. Currently, there is no mature, specifically designed electric pole-climbing robot for concrete utility poles that can effectively combine mechanical structure and power system to address the aforementioned shortcomings of traditional foot catches. Utility Model Content

[0004] The present invention aims to provide a robot for climbing cement utility poles, so as to achieve the technical goals of reducing the physical exertion of construction workers, improving the efficiency of climbing operations, and enhancing the safety of operations.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cement pole climbing robot includes a pole lifting mechanism, a support and fixing mechanism, and a seat. The pole lifting mechanism includes a notched annular clamp, a drive wheel, and a driven wheel. The notched annular clamp is inclined and the drive wheel is rotatably connected to the bottom of the inner side of the notched annular clamp. There are two driven wheels, which are rotatably connected to the left and right sides of the top of the inner side of the notched annular clamp. The drive wheel is driven to rotate by a drive motor fixed to the notched annular clamp or the support and fixing mechanism. The notched annular clamp has a notch on the bottom side for the cement pole to enter the center of the notched annular clamp. The support and fixing mechanism includes a mounting frame. The upper front part of the mounting frame is fixedly connected to the bottom of the notched annular clamp. A rechargeable battery electrically connected to the drive motor is installed in the mounting frame. The seat is located on the top of the mounting frame.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the seat is connected to the top of the mounting frame via an angle adjustment assembly at the bottom. The angle adjustment assembly includes a fixed sleeve, a connecting plate, a drive gear, a driven gear, and an angle adjustment motor. The top of the mounting frame is rotatably connected to a horizontal shaft via bearings on both sides. The fixed sleeve is coaxially fixed to the middle of the horizontal shaft, and the driven gear is coaxially fixed to the middle of the fixed sleeve. The drive gear meshes with the driven gear. The angle adjustment motor is fixedly connected to the mounting frame, and its output end is coaxially fixedly connected to the drive gear.

[0008] Furthermore, it also includes a control panel for controlling the start and stop of the drive motor and the angle adjustment motor.

[0009] Furthermore, one end of the horizontal shaft extends outside the mounting frame and is fixedly connected to the lower end of an obliquely extending support rod, the upper end of which is fixed with the control panel.

[0010] Furthermore, both ends of the horizontal shaft extend outside the mounting frame and are respectively connected to downward-extending L-shaped connecting rods, with a foot pedal fixedly connected to the lower end of the L-shaped connecting rod.

[0011] Furthermore, the mounting frame is made of stainless steel, and the seat is made of stainless steel or hard plastic.

[0012] Furthermore, the driving wheel and the driven wheel are respectively connected to the inner side of the notched annular clamp via U-shaped parts. The closed end of the U-shaped part is fixedly connected to the inner side of the notched annular clamp. The driving wheel and the driven wheel are located inside the corresponding U-shaped parts and are rotatably connected to the U-shaped parts via two rotating shafts on both sides.

[0013] Furthermore, the notched annular clamp is formed by bending square steel, and the lower outer side of the notched annular clamp is welded and fixed to the upper front side of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through its notched ring-shaped clamp and the design of one driving wheel and two driven wheels, combined with the counterweight effect of the mount and support mechanism, can easily achieve a tight grip on cement utility poles. Simultaneously, the driving wheel is directly driven by a geared motor (drive motor), enabling ascent and descent along the cement utility pole. The geared motor has a self-locking function, allowing the pole-climbing robot to remain stably on the cement utility pole when the motor stops. The method of the drive motor directly driving the driving wheel is simpler in structure, easier to install, and has higher transmission efficiency than traditional methods using chains or synchronous belts.

[0016] The seat can be adjusted in angle using an angle adjustment component, allowing construction workers to work in a better position and improving installation and work efficiency.

[0017] This pole-climbing robot overcomes the shortcomings of traditional manual pole climbing, significantly reducing the physical exertion of construction workers, allowing them to focus more on the power operation itself, and reducing safety risks caused by fatigue. Attached Figure Description

[0026] The technical solution provided by this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, if terms such as "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" are used to indicate the orientation or positional relationship, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1 to 6 As shown, this utility model provides a cement pole climbing robot, which includes a pole lifting mechanism, a support and fixing mechanism, and a seat 7. The pole lifting mechanism includes a notched annular clamp 1, a drive wheel 2, and driven wheels 3. The notched annular clamp 1 is inclined, and the drive wheel 2 is rotatably connected to the bottom inner side of the notched annular clamp 1. There are two driven wheels 3, which are rotatably connected to the left and right sides of the top inner side of the notched annular clamp 1. The drive wheel 2 is driven to rotate by a drive motor 4 fixed to the notched annular clamp 1 or the support and fixing mechanism. The notched annular clamp 1 has a notch on the bottom side for the cement pole to enter the center of the notched annular clamp 1. The support and fixing mechanism includes a mounting frame 5. The upper front part of the mounting frame 5 is fixedly connected to the bottom of the notched annular clamp 1. A rechargeable battery 6 electrically connected to the drive motor 4 is installed in the mounting frame 5. The seat 7 is located on the top of the mounting frame 5.

[0029] It should be noted that the cement pole climbing robot provided by this utility model adopts an integrated design of "clamping-power-control-load-bearing," achieving autonomous climbing operations through the synergy of mechanical structure and electric drive. The entire system consists of five parts: a clamping mechanism, a power drive unit, a control unit, an energy storage battery module, and a human-machine operation load-bearing module. These modules are mechanically connected and integrated with electrical circuits to form a complete system. The clamping mechanism, also known as the pole-lifting mechanism, includes a notched annular clamp made of high-strength alloy material (such as square steel) with an opening angle of 120°-150° (suitable for the diameter range of common cement poles). It possesses a certain degree of elastic deformation capability to adapt to different surface tolerances of the poles. When the cement pole enters the notched annular clamp, the clamp should first be laid as flat as possible. Then, aligning the notch with the pole horizontally, the clamp is moved forward to allow the pole to enter. Then, the clamp is released, and the entire robot, relying on the weight of the motor and rechargeable battery, presses and grips the pole with the drive and driven wheels. Both the driving wheel and the driven wheel are high-friction rubber wheels, arranged in a triangular pattern inside the notched annular clamp. The wheel diameter is approximately φ50mm, and the wheel surface is decorated with anti-slip texture. They are hinged to the clamping frame via the wheel axle, and can adaptively adjust the contact angle according to the curvature of the utility pole surface.

[0030] In one embodiment of this utility model, the seat 7 is connected to the top of the mounting frame 5 via an angle adjustment component at the bottom. The angle adjustment component includes a fixing sleeve 8, a connecting plate 9, a driving gear 10, a driven gear 11, and an angle adjustment motor 12. The top of the mounting frame 5 is rotatably connected to a horizontal shaft 13 via bearings on both sides. The fixing sleeve 8 is coaxially fixed to the middle of the horizontal shaft 13. The driven gear 11 is coaxially fixed to the middle of the fixing sleeve 8. The driving gear 10 meshes with the driven gear 11. The angle adjustment motor 12 is fixedly connected to the mounting frame 5, and its output end is coaxially fixedly connected to the driving gear 10.

[0031] It should be noted that both the drive motor and the angle adjustment motor are geared motors to ensure high torque output. The motor is preferably a DC brushless motor: 200W power, 48V rated voltage, 3000rpm speed, with overload protection and stall stop function; the reducer uses a three-stage reduction gearbox: transmission ratio 1:30, converting the high-speed rotation of the motor into low-speed, high-torque output from the rubber wheels. The gears undergo carburizing and quenching processes, with a lifespan ≥5000 hours. To ensure safety, the angle adjustment motor's adjustment angle can be set to a maximum adjustable angle, and this angle should ideally not exceed 5 degrees.

[0032] In one embodiment of this utility model, a control panel 14 is also included, which is used to control the start and stop of the drive motor 4 and the angle adjustment motor 12.

[0033] It should be noted that the controller in the control panel uses an STM32F4 series industrial-grade chip, integrating motor drive circuitry and logic control program to achieve closed-loop speed control. A wireless remote control module can also be configured as needed. This module supports 2.4G wireless communication, has a control distance of ≥50m, and includes buttons for ascending, descending, emergency stop, and speed adjustment.

[0034] In one embodiment of the present invention, one end of the horizontal shaft 13 extends outside the mounting frame 5 and is fixedly connected to the lower end of an obliquely extending support rod 15, and the control panel 14 is fixed to the upper end of the support rod 15.

[0035] In one embodiment of this utility model, both ends of the horizontal shaft 13 extend outside the mounting frame 5 and are respectively connected to downwardly extending L-shaped connecting rods. The lower end of the L-shaped connecting rod is fixedly connected to a foot pedal 16.

[0036] It should be noted that when the pole-climbing robot reaches a high point on the utility pole, if it tilts, the seat can be adjusted using the angle adjustment component to provide a more comfortable and safer posture for the worker sitting on it. The horizontal axis is mounted on the mounting frame via bearings, and the support rod and L-shaped connecting rod are connected to the horizontal axis. When the motor adjusting the seat rotates, it drives the rotating shaft through gear transmission, ensuring that the control panel and foot pedals always match the worker's sitting posture.

[0037] In one embodiment of this utility model, the mounting frame 5 is made of stainless steel, and the seat 7 is made of stainless steel or hard plastic.

[0038] In one embodiment of this utility model, the driving wheel 2 and the driven wheel 3 are respectively connected to the inner side of the notched annular clamp 1 through a U-shaped member. The closed end of the U-shaped member is fixedly connected to the inner side of the notched annular clamp 1. The driving wheel 2 and the driven wheel 3 are located in the corresponding U-shaped members and are rotatably connected to the U-shaped members through two rotating shafts on both sides.

[0039] In one embodiment of this utility model, the notched annular clamp 1 is formed by bending square steel, and the lower outer side of the notched annular clamp 1 is welded and fixed to the upper front side of the mounting frame 5.

[0040] In the above embodiments, the rechargeable battery is preferably a lithium battery, specifically a 48V / 10Ah lithium battery pack, which adopts a waterproof encapsulation design and is placed in a square battery compartment as shown in the attached figure.

[0041] The method of using the pole-climbing robot provided by this utility model is briefly described as follows: First, the utility pole is allowed to enter the center of the pole-climbing lifting mechanism through the notch of the notched annular clamp. After the notched annular clamp is subjected to the gravity of the mounting frame, seat, and rechargeable battery, it returns to its tilted position, and the drive wheel and driven wheel clamp the utility pole. Then, the construction worker sits on the seat to make the drive wheel clamp the pole even tighter. The construction worker starts the drive motor through the control panel to drive the drive wheel to climb the pole. When the desired height is reached, the drive motor is turned off, and the pole-climbing robot stops at that height. When it is necessary to descend, the drive motor is started again and reversed. When climbing to the designated height or during the pole climbing process, the posture of the pole-climbing robot may tilt to a certain extent. At this time, the construction worker starts the seat adjustment motor through the control panel. The motor drives the gears to adjust the posture of the seat through gear transmission, so that the seat is as perpendicular to the ground as possible.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
