Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution operation and maintenance equipment technology, and in particular to a pedal-type pole climbing device. Background Technology
[0002] In power grid operation and maintenance, power line workers must climb distribution poles to inspect the installation quality and maintain the operational status of equipment on the poles. With the expansion of distribution networks, distribution pole structures are diverse, and their distribution environments are complex, often involving residential areas, farmland, mountains, and roadsides. Some sections have undulating terrain, narrow passages, or are adjacent to buildings, making access difficult for personnel and equipment. Furthermore, operation and maintenance work frequently faces severe weather conditions such as strong winds, heavy rain, high temperatures, and low temperatures, significantly increasing operational risks and safety pressures.
[0003] Currently, individual pole-climbing operations for power distribution line maintenance still primarily rely on foot straps or climbing boards in conjunction with full-body safety harnesses. However, traditional foot straps or climbing boards have a core drawback: their force application mode is lateral. Specifically, when climbing a pole, the operator needs to push the foot straps or climbing boards outwards laterally with their legs, relying on lateral force to generate friction between the foot straps and the pole surface for fixation. This lateral force application method has several drawbacks: First, it requires precise control of the pressing angle and force, demanding a high level of skill and leg strength. Novices or those fatigued are prone to slipping their foot catches due to improper force application, leading to accidents. Second, the force is dispersed during lateral pressing and is easily affected by the pole's taper and surface flatness. When facing different types of poles, the frictional stability is poor, increasing operational risks. Third, prolonged lateral force application keeps leg muscles in an unnatural state of tension, easily leading to fatigue, reducing work efficiency, and is not conducive to long-term pole work. Fourth, the lateral force application structure requires multiple sets of screws and rivets to connect components and transmit lateral force. Too many connection points can easily deform, loosen, or even jam during long-term use, further weakening pole climbing safety. Summary of the Invention
[0004] The technical problem to be solved by this invention is that traditional pole climbing tools, which exert lateral force, are difficult to operate and pose high safety risks.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A pedal-type pole climbing device includes a base, a movable arm, a pedal module, a foot pedal module, and a gripper module; one end of the base is rotatably connected to one end of the movable arm; the pedal module is fixedly connected to the other end of the movable arm, and the other end of the movable arm is connected to the gripper module via an elastic element; the gripper module is fixedly connected to the base, and the foot pedal module is detachably connected to the pedal module.
[0006] The beneficial effects of this invention are as follows: by innovating the lateral force application mode of traditional pole climbing tools into an ergonomic longitudinal force application mode, specifically through the rotational connection between the base and the movable arm, and the linkage between the elastic element and the gripper module, the operator only needs to step on and lift the pedal module longitudinally with the ball of the foot to drive the gripper module to open and close. The force is transmitted by the weight of the human body, without the need for precise control of the pressing angle and force, which greatly reduces the dependence on the operator's technical proficiency and leg strength, and effectively avoids the risk of slippage caused by improper force application when the user is a novice or fatigued.

[0009] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0010] Please refer to Figures 1 to 15 A pedal-type climbing pole device includes a base, a movable arm 3, a pedal module 4, a foot pedal module 6, and a gripper module 5; one end of the base is rotatably connected to one end of the movable arm 3; the pedal module 4 is fixedly connected to the other end of the movable arm 3, and the other end of the movable arm 3 is connected to the gripper module 5 through an elastic element 10; the gripper module 5 is fixedly connected to the base, and the foot pedal module 6 is detachably connected to the pedal module 4.
[0011] As can be seen from the above description, the beneficial effects of the present invention are as follows: by means of the rotational connection between the base and the movable arm 3, and the linkage between the elastic element 10 and the gripper module 5, the operator only needs to step on the pedal module 4 longitudinally with the ball of the foot to drive the gripper module 5 to open and close, and use the weight of the human body to transmit the force, without the need for precise control of the pressing angle and force, which greatly reduces the dependence on the operator's technical proficiency and leg strength.
[0012] Furthermore, the gripper module 5 includes two gripping arms 51, which are symmetrically arranged arc-shaped structures; the fulcrum 52 of the gripping arms 51 is fixed to the base, and the gripping arms 51 can rotate around the fulcrum 52.
[0013] As can be seen from the above description, the two clamping arms 51 are symmetrically arranged arc-shaped structures that can accurately fit the circular contour of the distribution pole, ensuring that the clamping arms 51 are fully in contact with the surface of the pole when clamping, and can also build a stable lever transmission structure with the help of the fulcrum 52, so that the force transmitted by the operator through the movable arm 3 can be accurately transmitted to the clamping arms 51, realizing the smooth opening and closing of the gripper.
[0014] Furthermore, the gripper module 5 also includes a transmission component 53, with one end of the gripper arm 51 rotatably connected to one end of the transmission component 53.
[0015] As can be seen from the above description, the transmission component 53 can drive the clamping arm 51 to rotate stably around the fulcrum 52 according to the lever principle, thereby realizing the smooth opening and closing of the gripper.
[0016] Furthermore, it also includes a second connector 9, one end of which is rotatably connected to the transmission member 53, and the other end of the second connector 9 is fixed with a first protrusion 91. The other end of the movable arm 3 is fixed with a second protrusion 31, and the first protrusion 91 and the second protrusion 31 are connected by an elastic member 10.
[0017] As can be seen from the above description, through the cooperation of the first protrusion 91, the second protrusion 31 and the elastic element 10, the movement of the movable arm 3 can be accurately transmitted to the second connector 9 through the elastic element 10, thereby driving the clamping arm 51 to open and close smoothly; at the same time, the elastic characteristics of the elastic element 10 can automatically compensate for the slight displacement during the clamping process, ensuring the adaptive clamping force of the jaws on poles of different diameters, ensuring the stability of the clamping, and avoiding excessive clamping that could damage the pole or device.
[0018] Furthermore, the pedal module 4 includes a convex latch 42 and a pedal 41. The convex latch 42 includes a rod portion 422 and a tongue portion 421. One end of the rod portion 422 is fixed to the pedal 41, and the other end is fixed to the tongue portion 421.
[0019] As can be seen from the above description, this structural design not only ensures the firmness of the connection between the convex locking buckle 42 and the pedal 41, preventing loosening or breakage under force, but also achieves the cooperation and fixation with the foot pedal module 6 through the tongue 421.
[0020] Furthermore, the foot pedal module 6 includes a foot plate 61, on which an elongated slot 611 is formed. The length of the elongated slot 611 is greater than the length of the tongue 421; the width of the elongated slot 611 is greater than the width of the tongue 421 and less than the length of the tongue 421; the thickness of the foot plate 61 is less than the distance between the tongue 421 and the pedal 41.
[0021] As can be seen from the above description, the elongated slot 611 and the tongue 421 of the convex locking buckle 42 are precisely matched in size. The length and width of the elongated slot 611 are greater than the corresponding size of the tongue 421, which facilitates the quick insertion of the tongue 421. The design that the width is smaller than the length of the tongue 421 allows locking to be achieved by rotating after insertion, preventing the foot pedal module 6 and the pedal module 4 from accidentally separating. At the same time, the thickness of the foot plate 61 is smaller than the distance between the tongue 421 and the pedal 41, ensuring that the two fit tightly and are firmly connected.
[0022] Furthermore, the base includes a fixed arm 2, which is rotatably connected to one end of a movable arm 3. The connection of the fixed arm 2 is provided with a semi-circular groove 21, and the connection of the movable arm 3 is provided with a protrusion 32, which is embedded in the groove 21.
[0023] As can be seen from the above description, the protrusion 32 and the groove 21 limit the movement of the movable arm 3, which can only rotate relative to the fixed arm 2 along the trajectory of the groove 21. This prevents the movable arm 3 from rotating inward toward the fixed arm 2 during use, which would cause the clamping arm 51 to open when stepped on.
[0024] Furthermore, the foot pedal module 6 also includes a short side plate 62 and a long side plate 63, which are respectively fixed on opposite sides of the foot plate 61. A first strap 64 is provided between the short side plate 62 and the long side plate 63. A second strap 65 is provided at the end of the long side plate 63 away from the foot plate 61.
[0025] As can be seen from the above description, the foot pedal module 6 constructs a lateral protection frame through the short side plate 62 and the long side plate 63, and works with the first strap 64 to fix the foot laterally, while the second strap 65 specifically fixes the lower leg.
[0026] Furthermore, the base also includes a base 1 and a first connector 8. One end of the base 1 is fixedly connected to the other end of the fixed arm 2, and the fulcrum 52 of the clamping arm 51 is fixed to the base 1 through the first connector 8.
[0027] As can be seen from the above description, one end of the base 1 is fixedly connected to the other end of the fixed arm 2, forming a support carrier that links the base and the movable arm 3, ensuring the overall structural stability of the movable arm 3 when it rotates; at the same time, the fulcrum 52 of the clamping arm 51 is fixed to the base 1 through the first connecting piece 8, providing a firm installation and positioning for the clamping arm 51, so that the clamping arm 51 can rotate stably around the fulcrum 52 to achieve the clamping action.
[0028] Furthermore, the clamping arm 51 is provided with an anti-slip element 7 between the fulcrum 52 and the end away from the transmission component 53, and the base 1 is also provided with an anti-slip element 7 at the end away from the fixed arm 2.
[0029] As can be seen from the above description, both the clamping section of the clamping arm 51 and the base 1 are equipped with anti-slip parts 7. The double anti-slip design greatly improves the friction between the device and the surface of the distribution pole, effectively avoiding the risk of slippage caused by force or the condition of the pole surface during the pole climbing process.
[0030] Please refer to Figures 1 to 15 Embodiment 1 of the present invention is as follows: A pedal-type climbing pole device includes a base 1, a fixed arm 2, a movable arm 3, a pedal module 4, a foot pedal module 6, and a gripper module 5. One end of the fixed arm 2 is welded to one end of the base 1, and the other end is hinged to one end of the movable arm 3, ensuring a stable connection and precise rotation. The pedal module 4 is fixed to the other end of the movable arm 3. The movable arm 3 is connected to the gripper module 5 via a spring. The gripper module 5 is fixed to the base 1 via a first connecting member 8. The foot pedal module 6 and the pedal module 4 are detachably connected, forming a stable structure with coordinated operation. The gripper module 5 includes two symmetrically arranged arc-shaped gripping arms 51. The gripping arms 51 are fixed to the first connecting member 8 via a fulcrum 52 and can rotate around the fulcrum 52. One end of the gripping arm 51 is hinged to a transmission member 53, and the other end of the transmission member 53 is hinged to a second connecting member 9 with a first protrusion 91. The first protrusion 91 and the second protrusion 31 at the other end of the movable arm 3 are connected by a spring, realizing smooth force transmission and smooth opening and closing of the gripper. In its natural state, the elastic force generated by the deformation of the spring will continuously push the two clamping arms 51 to contract around the fulcrum 52, thereby keeping the clamping jaws closed.
[0031] In this embodiment, when it is necessary to clamp the power distribution pole, applying an external force to the spring's force-applying end overcomes the elastic force of the elastic element. This force, centered on fulcrum 52, transmits kinetic energy to the clamping arm 51 via the lever principle, causing it to open against the elastic force. Subsequently, the pole is placed into the open clamping jaws, and the spring's force-applying end is released. The spring's elastic force immediately takes over again, pulling the clamping arm 51 to close around fulcrum 52. Ultimately, the clamping jaws tightly adhere to the object's surface, and the resulting enormous clamping force and friction securely fix it to the power distribution pole.
[0032] In this embodiment, the pedal module 4 consists of a convex latch 42 and a pedal 41. One end of the rod portion 422 of the convex latch 42 is fixed to the center of the pedal 41, and the other end is fixed to the center of the tongue portion 421. The foot pedal module 6 is provided with a foot plate 61, on which an elongated slot 611 is provided. The length and width of the elongated slot 611 are both greater than the corresponding size of the tongue portion 421, and the width is less than the length of the tongue portion 421. The thickness of the foot plate 61 is less than the distance between the tongue portion 421 and the pedal 41, which is adapted to the convex latch 42 to achieve reliable locking. At the same time, a short side plate 62 and a long side plate 63 are fixed to both sides of the foot plate 61 of the foot pedal module 6, respectively. A first strap 64 is provided between the short side plate 62 and the long side plate 63, and a second strap 65 is provided at the end of the long side plate 63 away from the foot plate 61, forming a double fixing structure. In addition, anti-slip parts 7 are provided on the clamping arm 51 from the fulcrum 52 to the end away from the transmission component 53 and on the end of the base 1 away from the fixed arm 2, which further enhances the friction between the device and the distribution rod and ensures the stability of the clamping.
[0033] In this embodiment, a method for climbing a pole using a pedal-type climbing device is also provided. Before operation, three checks are performed: on the pole, the safety belt, and the device itself. The pole is checked for cracks, tilting, and a firm base to ensure stability. Each module is carefully inspected for cracks, wear, or corrosion. All components are ensured to be intact. The safety belt is checked to ensure it is within its warranty period, and that the D-rings and buckles are free from deformation or cracks, and that the belt itself is unworn. Ensuring personal and equipment safety is a prerequisite for climbing the pole. Before climbing, the operator places their left and right feet into the foot pedal module 6, securing their feet and thighs with straps. Then, the foot pedal module 6 is locked to the pedal module 4 using a locking buckle to prevent the pedal module 4 from falling off.
[0034] In this embodiment, the pole climbing process is as follows: Since the climber's foot is already locked to the pedal module 4 via the foot pedal module 6, one foot can be lifted to horizontally engage the pole. During this engagement, the clamping arm 51, driven by the climber's forward lean, moves the sliding arm 3 to clamp the pole until it is fully engaged. The second step involves holding the pole with both hands, lifting the other foot, opening the clamping arm 51, and placing the pole into the clamping structure. Stepping on the convex locking buckle 42 firmly clamps the pole with the other foot, utilizing the friction of the double anti-slip pads to prevent the device from wobbling. Simultaneously exerting force with both hands and the right foot, the body leaps upward nimbly. At this point, the person's center of gravity is entirely on the second foot. Immediately afterward, fasten the safety belt, and once stable, quickly wrap the safety belt around the pole and fasten it, forming the first layer of safety protection. Finally, repeat the first and second steps of the pole climbing process, alternating between climbing upwards. During the climb, the body should maintain a certain distance from the pole, relying mainly on the strength of the arms and legs, with the waist slightly protruding to avoid the chest and abdomen pressing against the pole, in order to ensure flexible movements and easy observation of the situation above, and the toes should be pointed as close as possible to the pole.
[0035] In this embodiment, the pole lowering process is as follows: First, release the heel of the foot closer to the pole's top from the contact with the convex locking buckle 42, causing the clamping arm 51 to open. Use the heel of the other foot to firmly clamp the pole by stepping on the convex locking buckle 42. Second, hold the pole with both hands, move the foot closest to the pole to the foot already clamping it, and then clamp and step on the pole to confirm a secure hold. Finally, release the heel that was clamping the pole, allowing the body's center of gravity to gradually shift downwards. Repeat steps one and two until reaching the ground. When nearing the ground, release the heel, separating the left and right foot clamping modules 5 from the pole one by one, landing safely. The base 1 remains stationary throughout the entire process. By switching the force of the left and right feet on the pedal 41, the clamping and securing are achieved, while the release and upward / downward movement are accomplished, thus realizing the pole lowering / lowering action. By rotating the protruding latch 42 on the bottom of the foot, the pedal 41 is separated from the footrest, and then the strap is released. The device is then disassembled and retracted. The entire process of climbing up and down the bar is now complete.
[0036] In summary, the pedal-type pole climbing device provided by this invention represents a fundamental innovation in the pole climbing force generation mode, shifting from the traditional horizontal to the vertical direction. It successfully addresses the core pain points of existing pole climbing tools, such as high safety risks, high operational difficulty, and weak adaptability. In terms of device structural design, the hinged linkage of the base 1, fixed arm 2, and movable arm 3 serves as the core transmission foundation. This is complemented by the symmetrical semi-circular arc-shaped gripper arm 51 of the gripper module 5, the transmission structure of the elastic element 10, and the double straps and self-locking structure of the foot pedal module 6, forming a collaborative and efficient operating system. The vertical force generation mode is highly ergonomic, utilizing the user's own weight to transmit force. This eliminates the need for precise control of the pedaling angle and force by the operator, significantly reducing reliance on skill and physical strength. Even beginners or those experiencing fatigue can operate stably. The gripper module 5, through the combination of elastic element 10 and lever principle, achieves adaptive gripping of distribution poles with different diameters and tapers. The dual anti-slip element 7 design of the gripping section of the clamping arm 51 and the supporting end of the base 1 further enhances gripping stability and effectively avoids the risk of slippage. The corresponding pole climbing method is clear and easy to operate. The comprehensive inspection and fixing steps before climbing the pole, as well as the orderly operation of alternating clamping and center of gravity transfer during climbing and descending, combined with safety belt protection measures, ensure the safety and efficiency of the entire operation. Meanwhile, the device adopts a modular design with few connection points, which not only has excellent portability and ease of maintenance, but also adapts to the needs of power distribution operation and maintenance pole climbing operations in complex environments such as residential areas, farmland, and mountains, as well as under harsh weather conditions.
