Description

Technical Field

[0001] This invention relates to an electrically assisted pole climbing device. Background Technology

[0002] Nowadays, power line towers are being built higher and higher. For example, 220kV line towers are generally over 50 meters high. When carrying out high-altitude power operations, the work site has always been moved vertically by human hands to the work location. This has been the case both in the past and present, both domestically and internationally. Vertical human climbing of towers is extremely physically demanding.

[0003] Meanwhile, workers working at heights (maintenance or construction) must carry appropriate safety equipment, maintenance tools and materials with them, and the weight they carry will seriously affect climbing speed or work efficiency.

[0004] The main body of the power transmission tower is basically vertical. When workers climb it, their bodies will naturally lean backward, which can result in a negative angle between the human body and the ground. This increases the skill difficulty of climbing, the fear of heights, and the safety hazard of falling.

[0005] Climbing towers and reaching high-altitude work positions relies on a type of iron tower material called "foot spikes." These "foot spikes" are semi-enclosed structures without any protective measures, posing a serious risk of falls to workers during vertical climbing and movement. A 50-meter iron tower is equivalent to a 16.6-story residential building (3 meters per floor). When carrying out a power outage maintenance operation (such as replacing tension insulators on a 220kV line), the worker carries a load of approximately 10kg (safety belt, safety helmet, 60-meter Φ16 working rope, personal tool kit (including two wrenches and pliers), and other necessary tools or fittings). Because the upper part of the tower is a vertical structure, when climbing to the upper part, the human body will be in a -5° to -10° upward and backward position, increasing the difficulty and strength of the climb. Therefore, the combination of free climbing, carrying a load, and the backward leaning of the body will result in severe physical exhaustion, slow speed, safety hazards, and inefficient operation.

[0006] Employees use "foot spikes" as climbing hardware. The foot spikes are alternately installed on both sides of the main tower structure (angle steel) at 40cm intervals up to the top. They are typically designed as a bolt-like rod with a 45° angled end to prevent hand or foot slippage and fall prevention. However, traditional foot spikes have a small foothold area, resulting in low friction or resistance. In wet conditions, outdoor work, or when shoes are covered in slippery mud, there are safety hazards during the climb without full-time protection. Therefore, there is a high risk of falls during high-altitude climbing, along with severe fear of heights, slow speed, and low work efficiency.

[0007] To address the issues of insufficient physical strength, fall risk, and inefficiency faced by power company employees during high-altitude maintenance and construction (specifically referring to the climbing process), an electric-assisted pole climbing device is proposed. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of existing electric-assisted pole climbing devices, which can reduce the load and increase the speed, while also providing fall protection during the climbing process.

[0009] The technical solution to achieve the above objective is: an electric assisted pole climbing device, including an outer shell, a traction component is provided inside the outer shell, the traction component is connected to a rope, the two ends of the rope are located outside the outer shell and are connected to an upper fixing component; a locking hole is provided on the lower end face of the outer shell, and the outer shell is connected to a lower fixing component through the locking hole.

[0010] Preferably, the traction assembly includes a brushless motor connected to the left side of the inner side of the outer casing. The output end of the brushless motor is connected to a rubber wheel. The rubber wheel is fixed to the middle of the rope by a suspension rope. Both ends of the rope are wound around the rubber wheel multiple times. The ends of the rope extend to the upper end of the outer casing.

[0011] Preferably, the traction assembly further includes a motor control circuit board, a motor driver, and a lithium battery. The motor control circuit board, the motor driver, and the lithium battery are all located on the right side of the inner side of the housing. The motor control circuit board and the motor driver control the brushless motor, and the lithium battery provides power to the brushless motor.

[0012] Preferably, the upper fixing component consists of two sets, respectively connected to both ends of the rope body; the upper fixing component includes a nylon flat strap, the lower end of which is connected to a rope length adjustment ring, and the rope length adjustment ring is connected to the rope body; the upper end of the nylon flat strap is looped and connected to an elastic ring, and the looped portion of the upper end of the nylon flat strap is connected to an index finger sleeve and a thumb sleeve.

[0013] Preferably, the upper fixing component further includes a remote control connecting finger sleeve, on which a remote control board is connected. The remote control board is provided with a motor wireless remote control button, and the remote control connecting finger sleeve can be worn on the operator's finger.

[0014] Preferably, the lower fixing component includes a safety belt, the two ends of which are connected by a connecting buckle, and the safety belt is connected to the buckle hole.

[0015] Preferably, the end of the rubber wheel facing away from the output end of the brushless motor is connected to a built-in rubber wheel bearing, and the rubber wheel is connected to the side wall of the outer casing through the built-in rubber wheel bearing.

[0016] Preferably, the outer casing is further provided with a direction switching switch, a speed control knob switch, and a power display screen that displays the power level of the lithium battery.

[0017] The beneficial effects of this invention are: This electric-assisted tower climbing device uses a traction component. A motor shortens one end of the rope and lengthens the other, using foot spikes as the fulcrum to pull the worker upwards. The worker climbs to the next level with the help of the traction component, similar to a winch pulling an object in reverse. This process is repeated until the top of the tower. The motor can achieve a pulling force of 15kg, reducing the load and increasing efficiency, while also providing protection throughout the entire high-altitude climbing process.

[0018] This electrically assisted pole climbing device utilizes a nylon webbing system. During climbing, the lower end of the webbing is connected to a rope length adjustment ring, which is then connected to the rope body. The upper end of the webbing is looped and connected to an elastic ring. The looped portion of the upper webbing also includes index finger and thumb loops. The thumb and index finger are respectively inserted into the thumb and index finger loops. A square elastic ring is sewn into the end of the webbing. The webbing passes through this elastic ring to form a movable elastic loop. When the elastic loop is open, it can be inserted into the pole's foot spikes. In the event of a fall, the elastic loop quickly contracts and secures itself to the pole's foot spikes. The webbing is indirectly connected to a safety belt, allowing the worker to suspend in the air without falling, thus providing fall protection during pole climbing. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] like Figure 1-10 As shown, the electrically assisted pole climbing device is characterized by comprising an outer shell 27, within which a traction assembly is installed. The traction assembly is connected to a rope 6, with both ends of the rope 6 located on the outside of the outer shell 27 and connected to an upper fixing assembly. A locking hole 10 is provided on the lower end face of the outer shell 27, through which the outer shell 27 is connected to a lower fixing assembly. The outer shell 27 is designed as a box, with two suspension ropes (the two ends of the rope 6) extending from the upper middle part. The two ends of the rope 6 are connected to stress points such as pole anchors. A worker wearing a safety harness is connected to the lower fixing assembly via the locking hole 10 at the bottom of the traction assembly.

[0024] Specifically, when climbing the tower, the worker attaches the outer casing 27 to the lower fixing component, which is worn around the waist. The worker's left and right hands are fitted with fixing components, and they grip the tower's foot spikes. The upper fixing component acts as the fulcrum for the traction component. A command is issued through the upper fixing component, causing the traction component to shorten one end of the rope 6 and lengthen the other, using the foot spikes as fulcrums to pull the worker upwards. The worker climbs to the next level using the traction component, a process similar to a winch pulling an object in reverse. This process is repeated until the top of the tower is reached.

[0025] This electrically assisted pole climbing device is a tool designed to assist manual climbing of power poles. The product can be temporarily attached to the worker's safety harness, and the reciprocating rotation of the motor pulls the worker upwards. Initial product testing showed that the 60W motor can achieve a pulling force of 15kg, significantly reducing the burden on workers climbing at heights while providing comprehensive safety protection throughout the climbing process.

[0026] like Figure 2 , 3 As shown in Figures 4, 5, and 10, the traction assembly includes a brushless motor 1, which is connected to the left end of the inner side of the outer casing 27. The output end of the brushless motor 1 is connected to a rubber wheel 5. The rubber wheel 5 is fixed to the middle of the rope body 6 by a suspension rope 8. Both ends of the rope body 6 are wound multiple times around the rubber wheel 5, and the ends of the rope body 6 extend to the upper end of the outer casing 27. The end of the rubber wheel 5 facing away from the output end of the brushless motor 1 is connected to a built-in rubber wheel bearing 9, and the rubber wheel 5 is connected to the side wall of the outer casing 27 through the built-in rubber wheel bearing 9.

[0027] like Figure 3 As shown, the traction assembly also includes a motor control circuit board 2, a motor driver 3, and a lithium battery 4. The motor control circuit board 2, motor driver 3, and lithium battery 4 are all located on the right side inside the housing 27. The motor control circuit board 2 and motor driver 3 control the brushless motor 1, and the lithium battery 4 provides power to the brushless motor 1. The housing 27 also includes a direction switch 11, a speed control knob switch 12, and a power display screen 13 that shows the battery level of the lithium battery 4.

[0028] Specifically, the motor control circuit board 2 and the motor driver 3 are the control chips for the brushless motor 1. When the motor wireless remote control button 16 on the remote control board 14 is pressed (the motor wireless remote control button 16 is self-resetting, meaning it receives power when pressed and disconnects power when released), the brushless motor 1 rotates forward. When the other motor wireless remote control button 16 is pressed (the self-resetting button receives power when pressed and disconnects power when released), the brushless motor 1 rotates in reverse. After switching the direction conversion switch 11 on the motor control circuit board 2, the rotation logic sequence of the brushless motor 1 is reversed; when the motor wireless remote control button 16 is pressed, the brushless motor 1 rotates in reverse, and when the other motor wireless remote control button 16 is pressed, the brushless motor 1 rotates forward. The speed control knob switch 12 on the motor control circuit board 2 controls the speed of the brushless motor 1. The lithium battery 4 provides power to the brushless motor 1, and the power display screen 13 displays the lithium battery 4's power level and remaining time.

[0029] Specifically, the output shaft of the brushless motor 1 has a rubber wheel 5, in which a built-in rubber wheel bearing 9 is embedded, and the built-in rubber wheel bearing 9 is welded to the inner shell of the outer casing 27. That is, the rotating shaft of the brushless motor 1 rotates synchronously with the connected rubber wheel 5.

[0030] Specifically, the rope 6 is wound around the rubber wheel 5. When the brushless motor 1 rotates forward, the rope wound around the rubber wheel 5 rotates and shortens. At this time, the end of the rope 6 uses the tower footing 18 as the fulcrum and pulls the personnel to the next floor (such as an inverted winch). At the same time, the rope 6 at the other end of the rubber wheel 5 extends. The personnel hang this rope 6 on the tower footing 18 of the next floor with their right hand. When the brushless motor 1 rotates in reverse, the rope 6 wound around the rubber wheel 5 rotates in the opposite direction. This process is repeated to pull the personnel up or down (the direction switch 12 needs to be switched).

[0031] Specifically, the rope fixing clip 8 is used to fix the rope 6 wound in the middle of the rubber wheel 5, to prevent the rope from spinning freely in the rubber wheel and thus making it impossible to pull.

[0032] like Figure 6 As shown, there are two sets of upper fixing components, which are respectively connected to the two ends of the rope body 6. The upper fixing components include a nylon flat strap 20, the lower end of which is connected to a rope length adjustment ring 24, and the rope length adjustment ring 24 is connected to the rope body 6. The upper end of the nylon flat strap 20 is wrapped into a loop and connected to an elastic ring 23. The looped part of the upper end of the nylon flat strap 20 is connected to an index finger sleeve 21 and a thumb sleeve 22.

[0033] like Figure 7 , 8 As shown, the upper fixing component also includes a remote control connecting finger sleeve 17, on which a remote control board 14 is connected. The remote control board 14 is provided with a motor wireless remote control button 16. The remote control connecting finger sleeve 17 can be fitted onto the operator's finger 19. The motor wireless remote control button 16 is a self-resetting single-button design. The self-resetting design means that when pressed, the switch emits a remote control indication, and when released, the remote control indication is disengaged.

[0034] Specifically, the motor wireless remote control has two buttons 16, one for each hand of the operator. These buttons are attached to the operator's fingers 19 via finger sleeves 17. During operation, pressing button 16 with the left finger sends a command, causing the brushless motor 1 to rotate left and begin operation. Similarly, pressing button 16 with the right finger causes the brushless motor 1 to rotate right and begin operation.

[0035] Specifically, the thumb and index finger are respectively inserted into the thumb sleeve 2 and the index finger sleeve 21. A square elastic ring 23 is sewn to the end of the flat strap. The nylon flat strap 20 passes through the elastic ring 23 to form a movable elastic band loop. When the elastic band loop is open, it can be inserted into the tower foot spike 18. When a person falls, the flat strap loop will quickly contract and fix itself in the tower foot spike 18. The nylon flat strap 20 is indirectly connected to the safety belt 26, so that the worker is suspended in the air without falling, thus achieving the protection against falling from height when climbing the tower.

[0036] Specifically, the lower end of the nylon flat strap 20 is connected to a rope length adjustment ring 24 and is connected to the traction assembly. The rope length adjustment ring 24 passes through the rope body 6 and achieves traction force fixation through multi-hole insertion or winding. The rope can be lengthened or shortened as needed in the rope length adjustment ring 24 to suit workers of different heights.

[0037] like Figure 9 As shown, the lower fixing component includes a seat belt 26, with both ends of the seat belt 26 connected by a connecting buckle 25, and the seat belt 26 connected to the buckle hole 10.

[0038] Specifically, according to electrical work regulations, workers at heights must wear safety harnesses. Therefore, during operation, the safety harness 26 is temporarily threaded through the buckle 25 and connected to the outer casing 27 via the buckle hole 10, integrating the upper fixing component, traction component, and lower fixing component of this product. The center of the main strap of the safety harness 26 serves as the traction attachment point, conforming to ergonomics. During traction, the hips and waist of the worker bear force simultaneously and evenly, and the worker remains upright during traction, facilitating climbing and reducing fear of heights. For example, in rock climbing, scientific evidence shows that when a person falls, the single point in the center of the waist of the safety harness is the optimal protective attachment point, while the rope being in front of the worker does not hinder climbing.

[0039] This electrically assisted pole climbing device uses an electric motor to assist in pole climbing, achieving a reduction in load and increasing speed. Preliminary estimates suggest an efficiency increase of 300%. During climbing, a nylon webbing 20 (with increased width for friction) is used to create an anti-slip loop, with the foot spikes at a high point serving as a safety attachment point. The lower part is secured to the waist of the safety harness, providing fall protection during the climb. The safety harness 26 is secured to the waist; its single-point and front-mounted design helps prevent rollover during a fall, keeping the body upright and reducing secondary injuries. The fall protection effect is improved, while reducing fear of heights; it is simple and convenient. The thumb loop 2 and index finger loop 21 made of the nylon webbing 20 (with increased width for friction) help secure the fingers, increasing the flexibility of the fall protection webbing. The finger loops formed by the webbing can be quickly slipped onto the pole spikes, achieving a high-point attachment point and fall protection. The motor remote control button is pressed while the webbing loops are tightening and securing, achieving a synchronized and quick overall operation.
