Description

Technical Field

[0001] The present invention relates to the technical field of aerial work equipment, and particularly relates to a manned pole climbing work device. Background Art

[0002] In the field of aerial work, especially in industries such as power, communication, and construction, manned pole climbing work is a common and important work method. Traditional pole climbing work methods, such as the foot loop pole climbing method and the ladder pole climbing method, although simple to operate, still require manual climbing, and at the same time, the working space is limited. Especially when facing uneven conditions such as uneven thickness, potholes, and damage on the pole surface, these traditional methods often cannot provide sufficient stability, and the operators are prone to deviation or imbalance due to the unevenness of the pole body, increasing the operation risk and safety hazards.

[0003] In addition, some existing modern equipment, such as insulated boom trucks and building insulated platforms, although they can improve safety, their operation efficiency is low. Moreover, they usually rely on a relatively flat environment and are restricted by the geographical environment and working space.

[0004] Therefore, in view of the problems of uneven pole surface and uneven pole thickness, there is an urgent need for a new type of manned pole climbing work device that can adapt to pole surfaces with different thicknesses and irregularities, and can provide sufficient stability and a large working space to ensure the safety and operation efficiency of the operators during the operation process. Summary of the Invention

[0005] (1) The technical problems to be solved by the present invention are: in the face of uneven conditions such as uneven thickness, potholes, and damage on the pole surface, how to ensure that the manned pole climbing work device can stably adapt to various irregular pole surfaces; at the same time, provide sufficient working space to ensure the safety and efficiency of the operators during the operation process.

[0006] (2) Technical Solution To solve the above technical problems, an embodiment of the present invention provides a manned pole climbing work device for the manned climbing of a pole with uneven thickness during the pole climbing operation process. The manned pole climbing work device includes: Two sets of symmetrically arranged support frames, which are respectively located on two opposite sides of the pole to be climbed. Clamping components are provided on the adjacent sides of the two sets of support frames for clamping two opposite sides of the pole; A driving mechanism, connected to the two sets of support frames, for the two sets of support frames to move towards or away from each other; Two sets of climbing mechanisms, which are respectively located on the other two orthogonal opposite sides of the pole, for driving the manned pole climbing work device to climb, descend, or stay stationary relative to the pole to be climbed through clamping friction; Linkage mechanism, connecting two sets of the support frames and the crawling mechanism. When the driving mechanism drives the two support frames to move towards or away from each other, the linkage mechanism synchronously drives the two sets of crawling mechanisms to approach or move away from the rod body to be climbed, so that the clamping assembly and the crawling mechanism form synchronous clamping on four sides of the rod body to be climbed.

[0007] Through the coordinated work of symmetrically arranged support frames and the linkage mechanism, it can adapt to the uneven surface of the rod body and ensure stable clamping force. The driving mechanism controls the movement of the support frames to achieve stable climbing or descending on the surfaces of rod bodies with different shapes and sizes, improving the operation efficiency and safety. At the same time, without complex external equipment or secondary operations, the reliability of the device is enhanced.

[0008] According to an embodiment of the present invention, there are two sets of the linkage mechanism. Each set of the linkage mechanism includes two sets of driving support arms. The outer ends of each set of the driving support arms are respectively hinged to the two sets of support frames, and the inner ends are respectively hinged to the corresponding crawling mechanisms. When the driving mechanism drives the two sets of support frames to move towards each other, the reduction amplitude of the distance between the outer ends of the two driving support arms of the same set of the linkage mechanism is greater than the reduction amplitude of the distance between the inner ends, driving the crawling mechanism to stick to the rod body to be climbed.

[0009] Through the setting of two sets of driving support arms in the linkage mechanism, when the driving mechanism drives the support frames to move towards each other, the crawling mechanism and the clamping assembly can move towards the rod body synchronously, so as to ensure that when the diameter of the rod body to be climbed changes, synchronous clamping in four directions can be realized, ensuring that the device always maintains stable contact under different rod body surface conditions, and effectively improving the operation stability and safety.

[0010] According to an embodiment of the present invention, the crawling mechanism includes: Support base body, hinged to the inner end of the driving support arm of the linkage mechanism; Friction driving component, arranged on the support base body for fitting the rod body to be climbed; Moving driving unit, driving the friction driving component to move the friction driving component along the surface of the rod body to be climbed.

[0011] The crawling mechanism is hinged to the inner end of the driving support arm of the linkage mechanism through the support base body, so that the crawling mechanism can stably contact the surface of the rod body. The friction driving component is driven by the moving driving unit after fitting the surface of the rod body to be climbed, so that the friction driving component can move smoothly along the surface of the rod body, thus ensuring the stability of the crawling mechanism during the operation process.

[0012] According to an embodiment of the present invention, the friction drive assembly includes multiple sets of climbing wheels arranged along the length direction of the pole to be climbed. Each set of climbing wheels has two connected by a fixed shaft, and multiple sets of the climbing wheels are interconnected through worm wheels and worm gears arranged on the fixed shaft, such that the climbing wheels are arranged in two rows and synchronously fit the pole to be climbed along the length thereof.

[0013] The climbing wheels extend in two rows and synchronously fit the surface of the pole to be climbed, ensuring that the friction drive assembly can always move uniformly along the surface of the pole during operation, providing stable frictional force. This structure effectively improves the adaptability of the device on uneven surfaces, ensures the stability and efficiency of the operation, and avoids problems such as uneven contact or sliding of the climbing wheels due to surface irregularities.

[0014] According to an embodiment of the present invention, the clamping assembly includes two sets of clamping wheels and elastic deflection buffer members. The clamping wheels are connected to the corresponding support frames through the elastic deflection buffer members, and the distance and deflection angle between the clamping wheels and the support frames are adjusted through the elastic deflection buffer members.

[0015] Ensure that the clamping wheels can be adaptively adjusted according to the irregularities of the surface of the pole to be climbed, avoid rigid contact caused by changes in the surface of the pole, thereby providing stable clamping force, effectively enhancing the adaptability of the device under different pole surface conditions, and ensuring that the clamping assembly always maintains the best contact state during the operation process.

[0016] According to an embodiment of the present invention, an abutting portion is provided on the abutting side of the support base; The crawling mechanism further includes a telescopic assembly. The friction drive assembly and the support base are connected through the telescopic assembly, and the telescopic assembly is configured to drive the crawling mechanism to retract or protrude the abutting portion along the radial direction of the pole to be climbed; When the friction drive assembly retracts, the abutting portion of the support base contacts and abuts against the surface of the pole to be climbed and locks.

[0017] When the crawling mechanism retracts, the abutting portion contacts and locks with the surface of the pole to be climbed, ensuring that the device can be firmly fixed on the pole during the working state, preventing sliding or instability. At this time, the elastic potential energy of the elastic deflection buffer member increases, and it can further increase the frictional force of the clamping assembly on the pole to be climbed.

[0018] According to an embodiment of the present invention, the manned pole climbing operation device further includes: A manned platform fixedly connected to one set of the crawling mechanisms, and a leaning portion is provided on the tabletop of the manned platform; The abutting parts of the two groups of the crawling mechanisms both include inclined abutting surfaces, and the two abutting surfaces have the same inclination direction as the rod body, so that when the abutting parts are locked with the rod to be climbed, the manned rod-climbing working device forms a backward-leaning operation inclination angle relative to the rod body to be climbed.

[0019] The abutting parts of the two groups of crawling mechanisms both include inclined abutting surfaces, and the two abutting surfaces have the same inclination direction as the rod body, ensuring that a backward-leaning operation inclination angle is formed between the manned platform and the rod body to be climbed during locking. At this time, the whole manned rod-climbing working device is in an inclined state, and the leaning part is located at the lowest position of the manned platform in this inclined state, thereby increasing the working space. The operator can lean on the leaning part obliquely, avoiding looking up at the high working area for a long time, and providing comfortable support for the operator. This design enables the operator to work in a more comfortable and stable posture during the work process, reduces the discomfort during long-term operation, increases the working space at the same time, and improves the convenience and comfort of the operation.

[0020] According to an embodiment of the present invention, fixed support frames and sliding support frames are respectively provided at the tops of the two groups of support bases; The manned platform is U-shaped and wound around the rod body to be climbed. The closed end of the U-shaped platform is fixedly connected to the support base through the fixed support frame, and the two open ends of the U-shaped platform are slidably connected to the support base through the sliding support frame.

[0021] Through the connection of the sliding support frame, the balance and stability of the manned platform during the operation are ensured, the instability caused by the unilateral support of the support base is avoided, and a more comfortable and safe working environment is provided.

[0022] According to an embodiment of the present invention, a transition arc surface for smoothly abutting against the rod body to be climbed is provided at the initial abutting position of the inclined abutting surface.

[0023] The setting of this transition arc surface can effectively reduce the stress concentration generated when the abutting surface contacts the rod body, ensure that the contact between the abutting surface and the rod body surface is smoother and more uniform, and at the same time avoid damaging the rod body surface.

[0024] According to an embodiment of the present invention, the manned rod-climbing working device further includes a control device, and the control device is used to connect and control the movements of the driving mechanism and the crawling mechanism; The control device includes a pressure sensor, and the pressure sensor is arranged on the clamping assembly and used to detect the contact pressure between the clamping assembly and the rod body to be climbed in real time; The control device automatically adjusts the movement parameters of the driving mechanism and the crawling mechanism according to the pressure value detected by the pressure sensor.

[0025] When the pressure is too high or too low, the control device will automatically adjust the movement speed or direction of the crawling mechanism and the distance between the two sets of support frames to ensure that the contact pressure between the clamping assembly and the crawling mechanism and the rod body is within an appropriate range, thereby effectively preventing the operation instability caused by poor contact or excessive pressure, and ensuring that the device can always maintain the best contact force with the rod body surface during the operation.

[0026] (III) Beneficial effects of the present invention: Through the synergistic effect of the symmetrically arranged support frames and the linkage mechanism, the manned pole climbing operation device of the present invention can adapt to uneven and pitted and damaged surfaces of the pole climbing, and ensure that the operation device forms a stable clamping force with the rod body surface. The driving mechanism controls the forward or reverse movement of the two sets of support frames to achieve stable climbing or descending on the surfaces of rod bodies with different thicknesses and irregular shapes, ensuring the stability of the device in a complex environment and significantly improving the operation efficiency and safety. At the same time, the device does not need to rely on complex external equipment or secondary operations, further improving the operation efficiency and reliability.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation modes. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention. Specific embodiment

[0031] As Figures 1 to 7 shown, this embodiment provides a man-carrying pole-climbing operation device, which is applicable to high-altitude operation tasks in industries such as electric power, communication and construction. It can adapt to pole surfaces of different thicknesses and irregular shapes, ensuring stability and efficiency during the operation process. Through the coordinated work of various components, this device can provide a comfortable and stable operation environment for the operators.

[0032] The core structure of this device includes a support frame 1, a crawling mechanism 2, a clamping assembly 11, a linkage mechanism 3, a man-carrying platform 4 and a control device. These components cooperate with each other to ensure that the operation device can climb, descend or remain stationary stably on poles with different shapes, sizes and irregular surfaces. The following is the detailed implementation plan of the present invention: As Figures 1 to 4 shown, the support frame 1 structure of the man-carrying pole-climbing operation device of the present invention is composed of two groups of symmetrically arranged support structures, which are respectively located on two opposite sides of the pole to be climbed 5. The main function of the support frame 1 is to provide stable support and ensure that the man-carrying operation device can contact the pole smoothly. The specific design of the support frame 1 can adopt various frame forms, and the specific form is flexibly configured according to actual needs. In this embodiment, the support frame 1 is composed of two support columns and two cross beams connecting the support columns.

[0033] The support columns are the main load-bearing parts of the support frame 1 and are usually made of high-strength steel or alloy materials to ensure that the support frame 1 does not deform when bearing loads; two cross beams connect the two support columns. The function of the cross beams is to provide support and provide an installation position for the clamping assembly 11 in the middle. The two ends of the cross beams are connected to the support columns by welding or bolts, and the connection method can be selected according to the working environment and load requirements of the device.

[0034] The driving mechanism 12 is connected to the two groups of support frames 1. In this embodiment, the driving mechanism 12 includes two groups of driving motors and lead screws. Each group of driving motors drives the movement of the support frame 1 through the lead screw. The support columns of the two groups of support frames 1 are respectively connected to the forward and reverse rotation of the lead screw. By rotating the lead screw through the driving motor, it is converted into a linear displacement. Due to the different connection directions of the lead screws, when the driving motor drives the lead screw to rotate, the support frames 1 can move synchronously towards or away from each other, so as to achieve precise clamping between the clamping assembly 11 and the rod body. The lead screw is made of high-strength materials to ensure stable operation under high loads, and to adapt to the operation requirements under different surface conditions, providing stable clamping force and support force; As Figure 4 And Figure 5 As shown, the clamping assembly 11 is installed in the middle of the cross beam and is connected to the inner side of the support frame 1, mainly used to assist in clamping the rod body 5 to be climbed, ensuring stability during the climbing process. The clamping assembly 11 includes two groups of clamping wheels 111 and elastic deflection buffer members 112. Each group of clamping wheels 111 consists of two wheel bodies, and these wheel bodies are connected to the clamping assembly 11 through bearings and can rotate freely to ensure stable friction with the surface of the rod body.

[0035] In this embodiment, the elastic deflection buffer member 112 is arranged in a Y shape, with the front end connected to the wheel body of the clamping wheel 111 and the rear end being the elastic deflection part. Through the design of the elastic deflection buffer member 112, the clamping wheel 111 can automatically adjust the angle according to the irregular situation of the rod body surface to ensure stable clamping force. In this embodiment, the deflection part is connected to the middle of the cross beam through an elastic torsion spring, and the elastic deflection of the torsion spring provides the necessary resilience and adjustment ability, enabling the clamping assembly 11 to adapt to the changes of the rod body.

[0036] In addition to the elastic torsion spring, the deflection function can also be achieved by other elastic elements, such as rubber springs or pneumatic springs, etc. These alternative solutions can also provide the required deflection and resilience capabilities to ensure that the contact force between the clamping wheel 111 and the rod body always remains within an appropriate range, thereby avoiding damage to the rod body caused by excessive friction or instability of the device due to insufficient clamping force.

[0037] Ensure that the clamping wheel 111 can be adaptively adjusted according to the irregularities on the surface of the pole to be climbed 5, avoid rigid contact caused by changes in the pole surface, thereby providing a stable clamping force, effectively enhancing the adaptability of the device under different pole surface conditions, and ensuring that the clamping assembly 11 always maintains the best contact state during the operation.

[0038] As Figure 4 shown, wherein, the linkage mechanism 3 serves as the core transmission unit for four-way clamping. Each group of mechanisms includes two driving support arms 31 arranged symmetrically in a V shape. The outer ends of the driving support arms 31 are connected to the columns of the two side support frames 1 by pin hinge means, and the inner ends are coupled to the support base 21 of the crawling mechanism 2 by a universal hinge structure. When the driving motor drives the support frames 1 to move towards each other, the distance between the outer hinge points of the driving support arms 31 contracts at a rate faster than the distance between the inner ends, forming a lever effect similar to a scissor mechanism. This differential motion transmission forces the two crawling mechanisms 2 to synchronously move towards the center of the pole along the radial direction orthogonal to the moving direction of the support frames 1, ensuring that the crawling mechanisms 2 and the clamping assemblies 11 in the four directions of the pole to be climbed 5 maintain a centrally symmetric clamping posture.

[0039] As Figure 5 and Figure 6 shown, the crawling mechanism 2 serves as the core driving unit of the device. There are two groups and they are symmetrically arranged on both sides of the pole, and are dynamically connected to the support frame 1 through the linkage mechanism 3. In actual operation, this mechanism adopts a modular design to adapt to different working conditions: for example, the multi-wheel synchronous structure drives the roller group to rotate synchronously through a motor-driven chain, or the crawler-type solution uses a rubber crawler to wrap the pole to achieve continuous friction drive. In this embodiment, the multi-wheel synchronous design is preferably adopted. Specifically, the cubic support base 21 bears three groups of climbing wheel 221 assemblies. Each group of climbing wheels 221 is connected into a double-wheel clamping unit through a fixed shaft 222, and the wheel surface is designed with anti-slip textures to enhance the grip. The worm 224 and worm gear 223 transmission system is embedded inside the base. When the moving drive unit 23 is started, the worm 224 drives the three groups of worm gears 223 to rotate synchronously, so that the two rows of climbing wheels 221 uniformly press along the axial direction of the pole. The V-shaped driving arms of the linkage mechanism 3 are hinged to the support base 21. When the support frames 1 move towards each other, the change in the included angle of the driving arms pushes the crawling mechanism 2 to radially contract, and the four clamping units form an envelope-type clamping. This design enables the device to adaptively fine-tune the angle of the climbing wheels 221 when encountering unevenness on the pole surface, maintain a stable power output and clamping force balance, and ensure a smooth and reliable climbing process.

[0040] Further, the support base 21 of the crawling mechanism 2 is a rectangular parallelepiped frame structure, and a metal abutting portion 211 with a trapezoidal cross-section is provided on the side facing the rod body. The surface of the abutting portion 211 is anti-slip treated to enhance the friction with the surface of the rod body. An expansion and contraction assembly 24 is installed inside the support base 21. This assembly consists of two groups of electric push rods arranged in parallel and connects the mounting frame of the friction drive assembly 22. When the device needs to be fixed, the electric push rods start to contract, pulling the friction drive assembly 22 to retract towards the center of the base along the linear guide rail embedded in the support base 21 until the abutting surface of the abutting portion 211 completely fits the surface of the rod body to form a lock in the working state.

[0041] The abutting portions 211 of the two groups of crawling mechanisms 2 both include inclined abutting surfaces, and the two abutting surfaces have the same inclination direction as the rod body, ensuring that a backward tilting operation inclination angle is formed between the manned platform 4 and the rod body to be climbed during locking. The manned pole climbing operation device realizes stable inclination and optimized operation space through a co-designed mechanical structure. Abutting portion 211 with a trapezoidal cross-section is provided on the side of the support base 21 facing the rod body, and the working surface of the abutting portion 211 is processed into an inclined surface with a fixed inclination angle. The inclined directions of the two side inclined surfaces are the same. When the expansion and contraction assembly 24 drives the friction drive assembly 22 to retract, the inclined surface of the abutting portion 211 fits and locks with the surface of the rod body, forcing the whole device to form a backward tilting posture. The manned platform 4 adopts a U-shaped frame structure. Its closed end is rigidly connected to the top of one side support base 21 through a fixed support frame 42, and the open end is slidably matched with the other side support base 21 through a sliding support frame 43. The sliding support frame 43 includes a linear guide rail and a slider assembly, allowing the platform to finely adjust its position along the axial direction of the rod body to balance the load. A gradually changing transition arc surface 2111 is provided at the initial position where the inclined surface of the abutting portion 211 contacts the rod body. The length of the arc surface matches the inclination angle of the inclined surface, gradually guiding the abutting portion 211 to uniformly contact the surface of the rod body during the locking process. An arc-shaped leaning portion 41 is provided at the lowest part of the U-shaped platform, and its curvature fits the contour of the human back. When the device is tilted backward and locked, the operator naturally leans on this place, and the head maintains a comfortable elevation angle to observe the working area.

[0042] Furthermore, the control device is integrated into the operation panel of the manned platform 4 and consists of a pressure sensing module, a central controller, and an actuator drive unit. The thin-film piezoresistive sensor of the pressure sensing module is embedded in the shaft seat of the clamping wheel 111 of the clamping assembly 11, and the contact pressure values of the four groups of clamping wheels 111 are fed back to the central controller in real time through wireless transmission. The central controller is built-in with an adaptive PID algorithm. When it detects that the pressure of any wheel group deviates from the preset range, it immediately generates an adjustment instruction: when the pressure is insufficient, the drive mechanism 12 increases the torque of the servo motor and speeds up the moving speed of the crawling mechanism 2, and at the same time reduces the distance between the support frames 1 to enhance the clamping force; when the pressure exceeds the limit, it reduces the motor output power and expands the distance between the support frames 1, and reverses the crawling mechanism 2 if necessary to relieve the pressure. The actuator drive unit synchronously controls the telescopic speed of the four groups of electric push rods and the rotation direction of the lead screw motor through the CAN bus to ensure that the four groups of clamping units always maintain dynamic balance during the clamping force adjustment process. The control panel is provided with multiple safety thresholds. When the pressure anomaly lasts for more than 2 seconds, it triggers an audible and visual alarm and activates the emergency brake, and the hydraulic locking mechanism synchronously intervenes to forcibly lock the device. This closed-loop control system enables the device to automatically compensate for the pressure fluctuations caused by the change in the rod diameter and the surface unevenness during the climbing process, and always maintain the optimal distribution of the contact force.

[0043] Working principle and usage method: Climbing process When the device starts the climbing mode, the drive mechanism 12 drives the two side support frames 1 to synchronously tighten towards the center of the rod. The V-shaped drive arm of the linkage mechanism 3 converts the horizontal displacement into a radial clamping force, pushing the friction drive assembly 22 of the crawling mechanism 2 to closely fit the surface of the rod. At this time, the drive unit of the crawling mechanism 2 is activated, and the friction assembly rolls along the rod to generate a thrust, and the device as a whole moves upward at a constant speed. The control device monitors the clamping force distribution in real time. If there are local depressions or protrusions on the rod, the clamping wheel 111 adaptively deflects through the elastic buffer structure, and the linkage mechanism 3 dynamically adjusts the distance between the support frames 1 to ensure the balanced transmission of the four-way clamping force and avoid slipping or deviation.

[0044] Descending control In the descending mode, the drive unit runs in reverse, the friction drive assembly 22 rolls in the reverse direction, and the device moves smoothly downward with the assistance of gravity. The linkage mechanism 3 maintains the clamping state, and the clamping assembly 11 always fits the surface of the rod to prevent free slipping. If it detects an abnormal descending speed (such as encountering an obstacle or a sudden change in the rod diameter), the control device immediately increases the clamping pressure and reduces the drive power, and triggers the hydraulic locking mechanism for emergency braking if necessary. The abutting part 211 quickly fits the rod to form a rigid fixation to ensure safe hovering.

[0045] High-altitude operation locking When the device needs to work in a fixed position, the telescopic component 24 contracts, the friction drive component 22 is completely retracted, and the inclined abutment portion 211 of the support base 21 fits tightly against the surface of the rod body, forming an irreversible rigid lock. At this time, the abutment surfaces with the same inclination on both sides force the device to lean back as a whole, and the manned platform 4 tilts to a preset angle. The operator leans against the arc-shaped backrest at the bottom of the U-shaped platform, with his head naturally tilted slightly up, and his line of sight is aligned with the high-altitude working point, balancing the center of gravity shift during the operator's operation. Once abnormal vibration or pressure fluctuation is detected, the sound and light alarm is immediately activated and forced locking is performed, providing double safety protection for high-altitude operations.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
