Description

Technical Field

[0001] This invention relates to the field of pole climbing high-altitude operations technology, and in particular to a pole climbing auxiliary device and a pole climbing operation method thereof. Background Technology

[0002] In the power industry, high-altitude operations often require climbing utility poles. Current technologies primarily employ two methods: First, workers wear climbing straps to grip the pole and climb independently. Second, a lifting platform is used, utilizing its telescopic function to adjust the work platform to the desired height on the pole. However, the first method suffers from slippage on the pole due to the straps, increasing the risk of worker missteps and posing a significant safety hazard, while also resulting in low efficiency. The second method involves a lifting platform that occupies considerable space around the pole, has limited lifting height, and is bulky, making it difficult to climb flexibly. Summary of the Invention

[0003] To overcome the problem of difficulty in flexibly climbing utility poles for high-altitude operations in existing technologies, this invention provides a pole climbing auxiliary device and a pole climbing operation method, which can effectively improve the connection stability between the device and the utility pole, improve operational safety, reduce space occupation, and improve the flexibility of climbing along the pole.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pole climbing auxiliary device, including a driving wheel, a driven wheel, a main frame and a control unit. The driving wheel and the driven wheel are respectively installed on the main frame. The driving wheel and the driven wheel are offset from the pole, so that the main frame is tilted and hung on the pole. The control unit is electrically connected to the driving wheel.

[0005] Furthermore, the driving wheel is mounted at a lower position on the pole than the driven wheel is mounted on the pole.

[0006] Furthermore, the driving wheel and the driven wheel are each provided with a ratchet mechanism, which is used to limit the driving wheel and the driven wheel from rotating counterclockwise and to brake them in the clockwise direction.

[0007] Furthermore, the outer walls of the driving wheel and the driven wheel are respectively provided with anti-slip rubber pads.

[0008] Furthermore, the main frame is provided with a lifting plate at one end for mounting the drive wheel, and the lifting plate is provided with a lifting ring for attaching the traction rope.

[0009] Furthermore, the lifting ring is equipped with a damping traction wheel.

[0010] Furthermore, the main frame is provided with two brake devices, which are used to brake the driving wheel and the driven wheel respectively, and the control unit is electrically connected to the brake devices.

[0011] Furthermore, the main frame includes a C-shaped steel frame and a movable rod, the C-shaped steel frame and the movable rod forming a ring structure, and the movable rod is used to control the opening and closing of the ring structure.

[0012] Furthermore, gravity sensing modules are distributed on the main frame, and the gravity sensing modules are electrically connected to the control unit.

[0013] Furthermore, the present invention also provides a pole climbing operation method, implemented based on the above-mentioned pole climbing auxiliary device, specifically including the following steps:

[0014] S1: The main frame is fitted onto the utility pole, so that the driving wheel and the driven wheel respectively abut against the utility pole;

[0015] S2: A lifting plate is mounted on the main frame, a lifting ring is set on the lifting plate, a traction rope is threaded through the lifting ring, and the two ends of the traction rope are placed on the ground;

[0016] S3: The control unit drives the drive wheel to rotate, causing the pole climbing auxiliary device to climb along the pole until the pole climbing auxiliary device reaches the working position;

[0017] S4: Use the control unit to brake the drive wheel, so that the drive wheel and the driven wheel are respectively stationary against the pole, and keep the pole climbing auxiliary device stationary at the working position on the pole;

[0018] S5: A heavy object is connected to one end of the traction rope, and a pulling force is applied to the other end of the traction rope by manpower or power equipment. The lifting ring serves as the fulcrum of the traction rope, so that the heavy object at the other end of the traction rope is lifted by force, thus completing the heavy object lifting operation.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention provides a pole climbing assist device that utilizes the offset contact between the driving wheel and the driven wheel and the pole, allowing the main frame to be tilted and hung on the pole. The device uses an angle balancing mechanism between the main frame and the pole to balance the force on the pole, and the offset arrangement of the driving wheel and the driven wheel increases the friction between the device and the pole, effectively improving the connection stability between the device and the pole, enhancing climbing stability and operational safety. Furthermore, the main frame of this invention can be directly hung on the pole for climbing, reducing additional space requirements and increasing flexibility compared to existing lifting devices.

[0021] Meanwhile, the pole climbing operation method based on the pole climbing auxiliary device provided by the present invention can lift heavy objects with the help of the pole climbing auxiliary device, and improve the connection stability between the device and the pole by utilizing the force balancing device for lifting heavy objects and the force between the pole. This improves the safety of the operation. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The present invention will be described in one embodiment below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present patent. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0032] Example 1

[0033] like Figure 1-5 As shown, this embodiment provides a pole climbing assist device that can be attached to a utility pole 4 to enable the device to automatically climb along the pole and hover safely and stably on the pole 4, avoiding slippage and improving safety. At the same time, heavy objects 9 can be hoisted onto the device for lifting heavy objects 9 in high-altitude operations. This device is lightweight, small in size, easy to carry, and highly flexible in use, and can meet the needs of various work scenarios.

[0034] Specifically, such as Figure 1-3 As shown, the pole climbing auxiliary device includes a main frame 3, a drive wheel 1, a driven wheel 2, and a control unit 11. The main frame 3 is used to mount the device onto the pole 4. The drive wheel 1 and the driven wheel 2 are respectively mounted on the main frame 3 and abut against the pole 4. The control unit 11 is used to electrically connect with the drive wheel 1. In use, the main frame 3 is mounted on the pole 4, so that the drive wheel 1 and the driven wheel 2 abut against the pole 4 respectively. The control unit 11 drives the drive wheel 1 to start. The friction between the drive wheel 1 and the pole 4 enables the device to climb along the pole. At the same time, the drive wheel 1 drives the driven wheel 2 to climb along the pole synchronously. This can maintain the climbing balance of the device and increase the contact area between the device and the pole 4, which is beneficial for climbing the pole and prevents slippage. The number of drive wheels 1 and driven wheels 2 can be adjusted and modified according to the usage.

[0035] Furthermore, in this embodiment, as Figure 6-7As shown, the main frame 3, as the main load-bearing structural component of the pole climbing auxiliary device, mainly consists of two parts: a C-shaped steel frame 310 and a movable rod 320. The C-shaped steel frame 310 and the movable rod 320 are assembled to form a ring structure. The movable rod 320 is movably connected to the open end of the C-shaped steel frame 310. By swinging the movable rod 320, the movable rod 320 can rotate around the C-shaped steel frame 310 to realize the opening and closing of the ring structure, which facilitates the locking and installation of the main frame 3 on the pole 4. Preferably, one end of the movable rod 320 is hinged to one end of the open end of the C-shaped steel frame 310, and the other end of the movable rod 320 is closed by a locking connection to the other end of the open end of the C-shaped steel frame 310.

[0036] Furthermore, in this embodiment, as Figure 6-7 As shown, the preferred design of the ring structure formed by assembling the C-shaped steel frame 310 and the movable rod 320 is a rectangular ring. This allows the length of the movable rod 320 to represent the maximum diameter of the pole 4 that can be fitted onto the main frame 3. Simultaneously, as... Figure 1-3 As shown, the driving wheel 1 and driven wheel 2 are preferably installed on opposite sides of the rectangular ring, so that the movable rod 320 is located between the driving wheel 1 and driven wheel 2. When the main frame 3 is installed on the pole 4, the driving wheel 1 and driven wheel 2 are offset relative to each other, and the driving wheel 1 and driven wheel 2 respectively abut against the pole 4. Preferably, the driving wheel 1 is set at a lower position than the driven wheel 2. Thus, the main frame 3 can limit the radial stress angle at the contact point between the device and the pole 4. Furthermore, the offset arrangement of the driving wheel 1 and driven wheel 2 on the pole 4 increases the friction between the device and the pole 4, improves the connection stability, prevents the device from detaching from the pole 4 or slipping, and increases operational safety.

[0037] Furthermore, in this embodiment, as Figure 6-7 As shown, it is preferable to make the four corners of the rectangular ring excessively rounded to avoid forming sharp structures that could cause bumps and damage.

[0038] Furthermore, in this embodiment, as Figure 1-3 As shown, the driven wheel 2 preferably includes an outer wheel 220 and an inner wheel 210. The inner wall of the outer wheel 220 is provided with ratchet teeth, and the inner wheel 210 is provided with a pawl that engages with the ratchet teeth. In this embodiment, the driven wheel 2 is preferably defined as rotating counterclockwise and braking clockwise. That is, through the engagement of the ratchet teeth and pawl between the inner wheel 210 and the outer wheel 220, the driven wheel 2 can only rotate counterclockwise and cannot rotate clockwise. Thus, during the process of the climbing auxiliary device climbing up the pole 4, the driven wheel 2 is passively rotated counterclockwise. At this time, there is rolling friction between the driven wheel 2 and the pole 4, which helps to improve the climbing efficiency. If the device has a tendency to fall during the ascent, the driven wheel 2 cannot rotate clockwise. At this time, there is sliding friction between the driven wheel 2 and the pole 4, which is used to prevent falling and improve the safety of use.

[0039] Specifically, such as Figure 1-3 As shown, in this embodiment, the driven wheel 2 is preferably installed at the top of the main frame 3, that is, at the top of the climbing pole auxiliary device. When the climbing pole auxiliary device is ascending along the pole, the driven wheel 2 follows the device upward. At this time, there is only rolling friction between the driven wheel 2 and the pole 4, which helps to improve the climbing efficiency. If the device accidentally falls and slides down, the driven wheel 2 will fall with the device. At this time, there is only sliding friction between the driven wheel 2 and the pole 4, which is used to slow down the falling speed. When the climbing pole auxiliary device is descending along the pole, the driven wheel 2 follows the device downward. At this time, rolling friction and sliding friction are allowed between the driven wheel 2 and the pole 4, which is used to balance the descent speed, avoid the device descending too fast and causing loss of control, and at the same time avoid the device descending too slowly and reducing the work efficiency, so as to keep the device descending speed within a reasonable range.

[0040] Furthermore, in this embodiment, in order to increase the friction between the driven wheel 2 and the pole 4, it is preferable to provide an anti-slip rubber pad on the driven wheel 2. This is beneficial for increasing the gripping force of the driven wheel 2 on the pole 4 when the device is rising, which is conducive to climbing. At the same time, it is beneficial for buffering the descent speed of the device in the event of an accidental fall, thereby improving the safety of use.

[0041] Furthermore, in this embodiment, it is preferable to design the driving wheel 1 with the same structure as the driven wheel 2, and preferably to install the driving wheel 1 at the bottom end of the main frame 3, that is, at the bottom end of the climbing pole auxiliary device, so as to cooperate with the driven wheel 2 to make the main frame 3 and the pole 4 tilt and hug tightly, that is, to form an angle lock between the main frame 3 and the pole 4, thereby improving the connection stability. At the same time, the driving wheel 1 can be driven by a motor, preferably a hub motor or a geared motor. The motor is electrically connected to the control unit 11. A gear set can also be set between the driving wheel 1 and the motor for speed adjustment, so as to flexibly control the climbing speed.

[0042] Furthermore, to prevent the climbing assist device from slipping off the pole 4 and to improve safety, in this embodiment, two brake devices are preferably installed on the main frame 3. The two brake devices are used to physically brake the drive wheel 1 and the driven wheel 2, respectively. Preferably, the brake devices are controlled by a relay adsorption method. The two brake devices are electrically connected to the control unit 11 to lock the drive wheel 1 and the driven wheel 2 when the climbing assist device accidentally falls off the pole 4. This ensures that in the event of an accidental fall, there is only sliding friction between the drive wheel 1 and the driven wheel 2 and the pole 4, thus braking the fall. At the same time, when the climbing assist device is climbing normally along the pole 4, the locking of the drive wheel 1 and the driven wheel 2 is released, allowing the drive wheel 1 and the driven wheel 2 to roll normally on the pole 4, improving climbing efficiency.

[0043] Specifically, in order to enable the climbing assist device to move flexibly and hover safely and stably on the pole 4, when the climbing assist device needs to be stationary on the pole 4, the control unit 11 activates the two brake devices to clamp and lock the driving wheel 1 and the driven wheel 2 respectively, so that there is only sliding friction between the driving wheel 1 and the driven wheel 2 and the pole 4, which is used to abut and lock the device on the pole 4. When the climbing assist device needs to climb on the pole 4, the control unit 11 activates the two brake devices to release the driving wheel 1 and the driven wheel 2 respectively, so that the driving wheel 1 and the driven wheel 2 can roll normally along the pole 4, improving the efficiency of the climbing operation.

[0044] Furthermore, such as Figure 1-4 As shown, to facilitate the hoisting of heavy objects 9 using the climbing pole auxiliary device, in this embodiment, a hoisting plate 5 is preferably provided on the main frame 3. The hoisting plate 5 is equipped with a hoisting ring 6 for installing the traction rope 8. Preferably, the hoisting plate 5 is positioned at one end of the main frame 3 where the drive wheel 1 is located. That is, when the hoisting plate 5 is connected to the heavy object 9 and subjected to force, the connection point between the main frame 3 and the hoisting plate 5 can be used as a fulcrum, causing the main frame 3 to tilt further. This, in turn, drives the drive wheel 1 and driven wheel 2 on the main frame 3 to approach and contact the pole 4, increasing the compressive force and improving the connection stability between the device and the pole 4. At this time, as... Figure 5 As shown, according to the force analysis, the load tension between the lifting plate 5 and the load 9 to be lifted, as well as the friction between the driving wheel 1, the driven wheel 2 and the pole 4, can be used to achieve the force balance of the pole climbing auxiliary device, so that the pole climbing auxiliary device can climb and stop stably on the pole 4. In this embodiment, it is preferable to design the lifting plate 5 and the main frame 3 to be foldable, which helps to save space. In addition, there is a mounting buckle between the lifting plate 5 and the main frame 3 to lock the folding angle of the lifting plate 5 relative to the main frame 3, thereby improving the operational stability of lifting the load 9.

[0045] In use, the climbing auxiliary device is mounted on the pole 4 using the main frame 3. The traction rope 8 is passed through the lifting ring 6, with one end of the traction rope 8 connected to the load 9 and the other end held by the operator. When the control unit 11 drives the drive wheel 1 to climb and rise along the pole 4, the drive wheel 1 and the driven wheel 2 drive the climbing auxiliary device to rise along the pole 4. The main frame 3 moves the lifting plate 5 to the working position. At this time, the operator can pull the handheld end of the traction rope 8 to lift the load 9 using the lifting ring 6 as the fulcrum, thus completing the lifting of the load 9.

[0046] Furthermore, such as Figure 5As shown, in order to save effort when hoisting the heavy object 9, this embodiment preferably sets a damping traction wheel 7 on the hoisting ring 6, and hangs a traction rope 8 on the damping traction wheel 7. One end of the traction rope 8 is connected to the heavy object 9, and the other end of the traction rope 8 is connected to the ground module 10. The ground module 10 includes electrical equipment for actuating the traction rope 8. When the climbing auxiliary device rises along the pole 4, it drives the damping traction wheel 7 to rise. The damping traction wheel 7 drives the traction rope 8 between the heavy object 9 and the ground module 10 to rise to form a fulcrum and build a lifting channel for the heavy object 9. When the climbing auxiliary device reaches the working position on the pole 4, the control unit 11 activates the brake device to lock the driving wheel 1 and the driven wheel 2, so that the climbing auxiliary device can achieve force balance by relying on the friction between the driving wheel 1, the driven wheel 2 and the pole 4, and the load tension between the hoisting plate 5 and the heavy object 9, and remain stationary at the height of the pole 4. Afterwards, the heavy object 9 can be lifted by manually or electrically pulling the traction rope 8.

[0047] Furthermore, in this embodiment, when there are clamps or other insurmountable obstacles on the surface of the pole 4, multiple climbing assistance devices can be installed on the pole 4, and each climbing assistance device is located on both sides of the obstacle. This allows the climbing height to be increased through multiple climbing assistance devices, thus creating a multi-level lifting channel for heavy objects 9.

[0048] Furthermore, in this embodiment, as Figure 8 As shown, the control unit 11 includes a controller and a human-machine interface system. The controller is used to electrically connect to the motor driving the drive wheel 1 and to electrically connect to the brake device to realize the driving and braking of the pole climbing auxiliary device. The controller can also be used to send and receive remote control signals. The human-machine interface system includes a remote control handle for connecting to the controller to facilitate wireless control of the pole climbing auxiliary device by the operator.

[0049] Meanwhile, in this embodiment, as Figure 8 As shown, the control unit 11 is also equipped with a gravity sensing module, which is used to acquire the real-time force status of the climbing auxiliary device and the load of the damping traction wheel 7, and transmit the force data to the controller. After analyzing the force data, the controller can adjust the driving speed of the drive wheel 1 and the start and stop of the brake device to prevent the climbing auxiliary device from falling on the pole 4, and monitor the lifting status of the heavy object 9 in real time to avoid the danger of falling. Preferably, the gravity sensing module in this embodiment is a number of pressure sensors, which are set between the main frame 3 and the pole 4, between the drive wheel 1 and the pole 4, between the driven wheel 2 and the pole 4, and between the hoisting plate 5 and the main frame 3, to sense and acquire the force status at various parts of the device.

[0050] Meanwhile, in this embodiment, the control unit 11 is also equipped with a speed sensing module, which is used to obtain the running speed of the driving wheel 1, the driven wheel 2 and the damping traction wheel 7. The running speed can be transmitted to the controller, and the controller can adjust the climbing speed of the climbing auxiliary device along the pole 4 to improve the running stability. When the heavy object 9 is hoisted, the running speed of the damping traction wheel 7 is sensed, and the damping of the damping traction wheel 7 is controlled to counteract the driving force of the ground module 10 to ensure that the heavy object 9 is raised and lowered smoothly.

[0051] Furthermore, this embodiment also includes a power supply module 12 for supplying power to devices such as motors and controllers.
