Description

Technical Field

[0001] This invention relates to the field of pole climbing auxiliary devices, specifically a pole lifting device and its usage method. Background Technology

[0002] This invention relates to the field of aerial work equipment technology, specifically to a pole lifting device, which is particularly suitable for the installation, inspection and maintenance of upright poles such as utility poles, street light poles and monitoring poles in industries such as power, communications and municipal engineering.

[0003] Currently, in pole-mounted high-altitude operations in the aforementioned fields, the traditional and commonly used operating methods mainly include the following: 1. Traditional manual pole climbing with foot straps relies entirely on workers using foot straps and safety harnesses to climb the pole by hand. This method has significant drawbacks: First, it requires extremely high physical strength and technical proficiency from the workers. The climbing process consumes a lot of physical strength, easily leading to fatigue, which directly affects the safety and quality of subsequent high-altitude operations. Second, workers need to frequently climb up and down the pole to retrieve tools and materials, greatly increasing the labor intensity and the risk of falls.

[0004] 2. Using aerial work platforms or insulated boom lifts: These mechanical devices lift the work platform to a high altitude, which reduces the climbing burden on personnel to some extent, but their limitations are also very prominent: the cost of purchasing and leasing the equipment is high; there are strict requirements on the road conditions and working space at the construction site, and it is often impossible to enter and operate in areas such as narrow alleys, rugged mountains or soft ground; their large size also makes it inconvenient to move between sites and has poor flexibility.

[0005] 3. Using ladder trucks or scaffolding provides a relatively stable working platform, but it has problems such as complicated installation and dismantling, difficult transportation, large footprint, low efficiency, and is also limited by terrain, making it difficult to adapt to various complex outdoor working environments.

[0006] In summary, existing pole-mounted operation methods all have significant drawbacks: they are either inefficient and pose high safety risks (such as manual pole climbing), or costly and unsuitable for use (such as work vehicles), or bulky, inconvenient, and lack flexibility (such as ladder truck scaffolding). The industry has long lacked a dedicated pole-mounted operation lifting device that can simultaneously achieve high efficiency, safety, economy, portability, and adaptability. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an efficient, safe, economical and portable pole lifting device and its usage method.

[0008] The technical solution adopted by this invention to solve its technical problem is: A pole lifting device includes a transport platform with a climbing frame installed at the bottom of the transport platform. The climbing frame is adapted to be installed on the pole to be climbed. A hydraulic rod is installed at the bottom of the climbing frame, with the output end of the hydraulic rod facing the pole to be climbed and a drive wheel installed at the output end of the hydraulic rod. The climbing frame is also equipped with a drive motor, a driven wheel, and a friction block. The output end of the drive motor is connected to the drive wheel. The driven wheel is installed on the side of the climbing frame facing the pole to be climbed and abuts against the pole to be climbed. The friction block is located inside the climbing frame and is detachably engaged with the pole to be climbed.

[0009] As a preferred embodiment, a further technical solution of the present invention is: Preferably, a limiting groove is provided on the inner side of the climbing frame corresponding to the position of the friction block, a ball set is embedded in the limiting groove, and a wear-resistant rotating sleeve is sleeved on the outer side of the friction block. The wear-resistant rotating sleeve is snapped on the outer side of the ball set and rotates in cooperation with the limiting groove.

[0010] Preferably, it also includes a power supply and a remote control, with the power supply electrically connected to the drive motor and the remote control wirelessly connected to the drive motor.

[0011] Preferably, the hydraulic rod is inclined along the bottom of the climbing frame toward the pole to be climbed, and the inclination angle of the hydraulic rod is 30°~60°.

[0012] Preferably, the friction block is made of wear-resistant rubber.

[0013] Preferably, the climbing frame includes two symmetrically arranged arc-shaped clamping arms, the ends of which are connected by a detachable bolt assembly.

[0014] Preferably, it also includes a safety rope; the upper end of the safety rope is fixedly connected to the top of the pole to be climbed or to a fixed point above the working height; the lower end of the safety rope is connected to the transport platform via an automatically locking fall arrestor.

[0015] The present invention also discloses a method for using a pole-mounted lifting device, the specific steps of which are as follows: Installation and fitting: The climbing frame is fitted onto the pole to be climbed, thus completing the installation and fitting of the device with the pole to be climbed. During the lifting operation, when climbing or lowering the pole, the hydraulic rod extends, causing the drive wheel and driven wheel to come into contact with the pole to be climbed, the friction block to separate from the pole, the drive motor to drive the drive wheel to rotate and pull the climbing frame up and down along the pole to be climbed, and the transport platform to rise and fall synchronously with the climbing frame. Once the designated height is reached, the hydraulic rod retracts, causing the friction block to come into close contact with the pole to be climbed. The drive motor then stops running, and the transport platform is fixed to the pole using gravity and friction.

[0016] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: By integrating drive wheels, hydraulic rods, and a remote control system, the automatic lifting of the transport platform is realized, fundamentally revolutionizing the operation mode from manual climbing to mechanical lifting. In terms of safety, a triple protection system of friction braking, anti-fall lock, and independent safety rope is constructed. At the same time, with the advantages of detachable modular structure and wireless control, it combines efficient operation, low-cost maintenance, and strong environmental adaptability, comprehensively solving the industry pain points of traditional pole climbing methods and aerial work platforms in terms of efficiency, safety, and cost.

[0019] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0020] like Figure 1 As shown in the figure, this embodiment provides a pole lifting device, including a transport platform 8, a climbing frame 2 installed at the bottom of the transport platform 8, the climbing frame 2 being adapted to be installed on the outside of the pole 1 to be climbed, a hydraulic rod 3 installed at the bottom of the climbing frame 2, the output end of the hydraulic rod 3 facing the pole 1 to be climbed, and a drive wheel 4 installed at the output end of the hydraulic rod 3, the climbing frame 2 also being provided with a drive motor, a driven wheel 5, and a friction block 6; the output end of the drive motor is connected to the drive wheel 4 for transmission, the driven wheel 5 is installed on the side of the climbing frame 2 facing the pole 1 to be climbed and abuts against the pole 1 to be climbed, and the friction block 6 is located inside the climbing frame 2 and is detachably engaged with the pole 1 to be climbed. The drive wheel 4 and the driven wheel 5 are both rubber-coated metal wheels (80mm in diameter, 30mm in width). The friction block 6 is made of wear-resistant rubber.

[0021] like Figure 2 The inner side of the climbing frame 2, corresponding to the position of the friction block 6, is provided with a limiting groove 9. A ball bearing assembly 10 is embedded in the limiting groove 9. A wear-resistant rotating sleeve is fitted onto the outer side of the friction block 6, and the wear-resistant rotating sleeve is snapped onto the outer side of the ball bearing assembly 10 and rotates in cooperation with the limiting groove 9. Specifically, the limiting groove 9 has a groove width of 30mm and a groove depth of 15mm. The ball bearing assembly 10 is made of standard carbon steel balls (8mm in diameter, 30-40 balls, evenly arranged), and the wear-resistant rotating sleeve is made of nylon PA6 material.

[0022] It also includes a power supply 7 and a remote control. The power supply 7 uses a rechargeable lithium battery pack (model: 18650, 24V / 10Ah) with a built-in charging protection board. The power supply 7 is electrically connected to the drive motor and hydraulic rod 3. The remote control is wirelessly connected to the drive motor. The remote control is an industrial wireless remote control F21-E1B.

[0023] The hydraulic rod 3 is inclined along the bottom of the climbing frame 2 towards the pole body 1 to be climbed, and the inclination angle of the hydraulic rod 3 is 30°~60°.

[0024] The climbing frame 2 includes two symmetrically arranged arc-shaped clamping arms, the ends of which are connected by a detachable bolt assembly. Specifically, each end of the two arc-shaped clamping arms is welded with a connecting lug, and the two connecting lugs are detachably connected by an M8 stainless steel bolt assembly.

[0025] It also includes a safety rope; the upper end of the safety rope is fixedly connected to the top of the pole 1 to be climbed or to a fixed point above the working height; the lower end of the safety rope is connected to the transport platform 8 via an automatically locking fall arrestor. The safety rope is a high-altitude work fall arrestor safety rope (model YL-10, diameter 12mm, breaking strength 15kN); the upper end of the safety rope is fixedly connected to the top of the pole 1 to be climbed or to a fixed point above the working height via a self-locking buckle, and the fall arrestor is a model TXS-2 connector.

[0026] The present invention also discloses a method for using the lifting device of the pole 1, the specific steps of which are as follows: Installation steps: First, loosen the bolt assemblies on the two arc-shaped clamping arms of the climbing frame 2 to open the climbing frame 2. Then, place the opened climbing frame 2 on the outside of the pole body 1 to be climbed, so that the driven wheel 5 naturally abuts against the pole body 1. Then, tighten the bolt assemblies to complete the initial installation and coordination between the device and the pole body 1 to be climbed. After installation, fix the upper end of the safety rope to the fixing point at the top of the pole body 1 and connect the lower end to the fall arrestor of the transport platform 8. Check the firmness of the connection of each component to ensure that there is no looseness.

[0027] Lifting and lowering operation steps: During the lifting and lowering operations, the hydraulic rod 3 is extended by remote control. The hydraulic rod 3 pushes the drive wheel 4 towards the rod body 1 until the drive wheel 4 is in close contact with the rod body 1. At this time, the driven wheel 5 is in closer contact with the rod body 1 due to the contact force of the drive wheel 4. The friction block 6 is completely separated from the rod body 1 (5-10mm gap) as the hydraulic rod 3 extends. Then, the drive motor is started by remote control. When the drive motor rotates clockwise, it drives the drive wheel 4 to rotate clockwise. The friction between the drive wheel 4 and the rod body 1 causes the climbing frame 2 to rise and fall along the rod body 1. When the drive motor rotates counterclockwise, it drives the drive wheel 4 to rotate counterclockwise, pulling the climbing frame 2 to rise and fall along the rod body 1. The transport platform 8 moves synchronously with the rise and fall of the climbing frame 2. During the lifting and lowering process, the speed of the drive motor can be controlled in real time by remote control.

[0028] Fixed operation steps: After the transport platform 8 reaches the designated working height, the hydraulic rod 3 is first retracted by the remote control. The hydraulic rod 3 drives the drive wheel 4 to move away from the pole 1. The contact force between the drive wheel 4, driven wheel 5 and the pole 1 disappears. At the same time, the friction block 6 is tightly abutted against the pole 1 to be climbed as the hydraulic rod 3 retracts. Using the weight of the device itself and the friction between the friction block 6 and the pole 1, the transport platform 8 is stably fixed on the pole 11 to be climbed. After the fixing is completed, the drive motor is stopped by the remote control, and the operator can then carry out high-altitude work on the transport platform 8.

[0029] Horizontal rotation operation steps: When it is necessary to adjust the working angle of the transport platform 8 during the operation, a slight pushing / pulling force is manually applied to the transport platform 8 in the target direction. At this time, the actions of each component are coordinated as follows: Under the manual force, the wear-resistant rotating sleeve rotates circumferentially along the ball set 10 in the limiting rotating groove 9. The ball set 10 converts the sliding friction between the wear-resistant rotating sleeve and the limiting rotating groove 9 into rolling friction, reducing rotational resistance and ensuring smooth rotation; the friction block 6 rotates synchronously with the wear-resistant rotating sleeve, maintaining a tight contact with the rod 1, without affecting the fixed stability of the device; the climbing frame 2, hydraulic rod 3, drive wheel 4, and driven wheel 5 all remain fixed, with only the wear-resistant rotating sleeve, friction block 6, and transport platform 8 forming a synchronous rotation structure. After the transport platform 8 is adjusted to the target working angle, the applied force can be released. During the rotation, the safety rope swings adaptively with the rotation of the transport platform 8, and the fall arrestor remains locked and ready, without affecting the rotation and ensuring operational safety.

[0030] It should be noted that the transport platform 8 can be used to transport personnel working at heights, as well as tools, accessories and other items required for the operation of the pole 1, thus meeting the dual needs of personnel transportation and material transfer for high-altitude operations.

[0031] The transport platform 8 of this device can simultaneously transport personnel working at height and transfer tools, accessories, materials, and other items. This effectively solves the industry pain points of traditional manual pole climbing operations, such as limited carrying capacity and the need for frequent climbing up and down the pole 1 to retrieve materials. It significantly reduces the labor intensity of workers and the risk of falls from height, further improving the overall efficiency and continuity of pole 1 operations at height. At the same time, it takes into account the safety of personnel transport and the convenience of material transfer. A single platform achieves dual functions without the need for additional material transport equipment, reducing the equipment investment cost for high-altitude operations. It is also more suitable for pole 1 operations in complex outdoor scenarios in industries such as power, communications, and municipal engineering.
