Description
Technical Field
[0001] This invention relates to the field of power construction and maintenance facilities and equipment technology, and in particular to a pole climbing device. Background Technology
[0002] Traditional pole climbing devices have a major flaw: in actual working scenarios, the diameter of the pole gradually decreases from the bottom up. When the operator climbs, every one or two steps, they have to readjust the size of the device opening by manually tightening screws or adjusting buckles through complex mechanical operations. After the adjustment is completed, it must be manually fixed again to ensure a perfect fit with the ever-changing thickness of the pole. Summary of the Invention
[0003] This invention provides a pole climbing device to solve the problem in the prior art that requires manual adjustment and fixing of the opening width of the device to adapt to the constantly changing diameter of the pole.
[0004] The present invention provides a pole climbing device, comprising: a first clamp, a second clamp, a foot pedal assembly, a locking component, and an unlocking component;
[0005] One end of the first clamp is rotatably connected to one end of the second clamp, and the other end of the first clamp is connected to the foot pedal assembly; the first clamp is provided with a first contact rod portion, and the second clamp is provided with a second contact rod portion, the first contact rod portion and the second contact rod portion being used to contact the rod on opposite sides of the rod body respectively;
[0006] The foot pedal assembly is disposed on one side of the first contact rod portion and is opposite to the contact rod end face of the first contact rod portion;
[0007] The locking member is located at the rotation point between the first clamp and the second clamp, and is used to control the second clamp to rotate unidirectionally around the first clamp, and to lock in the opposite direction, so that the first clamp and the second clamp clamp the rod.
[0008] The unlocking component is connected to the locking component, and the unlocking component is used to unlock the locking component, so that the second clamping component can rotate bidirectionally around the first clamping component.
[0009] Furthermore, the locking member includes a ratchet and a pawl. The ratchet is fixedly connected to the rotating end of the second clamping member, and the pawl is fixedly connected to the rotating end of the first clamping member. The pawl is located on one side of the ratchet and contacts the ratchet.
[0010] Furthermore, one end of the first clamp and one end of the second clamp are connected by a rotating structure. The rotating structure includes a column and a collar. The column is connected to the second clamp and is fixedly connected to the ratchet and coaxially arranged. The collar is connected to the end of the first clamp and is sleeved on the column to realize the rotatable connection between the first clamp and the second clamp.
[0011] Furthermore, the unlocking component includes an adjusting rod, an elastic element, and a telescopic element. The pawl is fixedly connected to the adjusting rod, the middle portion of the adjusting rod is rotatably connected to the first clamping member, one end of the adjusting rod is connected to one end of the elastic element, the other end of the elastic element is fixedly connected to the first clamping member, and the other end of the adjusting rod is connected to the telescopic element. The telescopic element is used to stretch the elastic element when it contracts, and the adjusting rod rotates around its middle portion to disengage the pawl from the ratchet. The telescopic element is used to extend when the elastic element recovers, and the adjusting rod rotates around its middle portion to engage the pawl with the ratchet.
[0012] Furthermore, the telescopic component includes a fixed tube, a strip, and a puller. The fixed tube is fixed to the first clamp. The strip penetrates the interior of the fixed tube and is movably connected to the fixed tube. One end of the strip is exposed outside the fixed tube and connected to the adjusting rod. The other end of the strip is connected to the puller, and the puller abuts against the end of the fixed tube.
[0013] Furthermore, the puller includes a first frustum and a second frustum, both of which are axially provided with through holes. The strip-shaped member passes through the through holes. The larger diameter end of the first frustum is fixedly connected to the end of the fixed tube. The larger diameter end of the second frustum is fixedly connected to the end of the strip-shaped member. The smaller diameter end of the first frustum abuts against the smaller diameter end of the second frustum.
[0014] Furthermore, the contact rod ends of the first and second contact rod portions are provided with rubber.
[0015] Furthermore, the foot pedal assembly is higher or lower than the first contact rod portion.
[0016] Furthermore, a vertical rod is provided at the connection end between the first clamp and the foot pedal assembly. The top of the vertical rod is connected to the first clamp, the bottom of the vertical rod is connected to the foot pedal assembly, and the first contact rod is located in the middle or at the top of the vertical rod.
[0017] Furthermore, it also includes a foot fixing component, which includes a first fixing strap, a second fixing strap, and a third fixing strap. The first fixing strap is disposed on the foot pedal assembly and is used to fix the foot pedal assembly to the middle of the foot. The second fixing strap and the third fixing strap are both disposed on the vertical bar. The second fixing strap is used to fix the ankle, and the third fixing strap is used to fix the lower leg.
[0018] As can be seen from the above technical solutions, the present invention has the following advantages: the locking member controls the second clamp to rotate unidirectionally around the first clamp, so that the first clamp and the second clamp clamp the pole body. The angle between the first clamp and the second clamp can be adjusted according to the diameter of the pole body, thereby adapting to different diameters of the pole body; the reverse rotation of the locking member prevents the second clamp from turning back and loosening during the climbing process, eliminating the need to manually fix the angle between the first clamp and the second clamp, and ensuring the safety of the pole climbing operation; the unlocking member unlocks the locking member to achieve bidirectional rotation of the second clamp, which facilitates quick adjustment of the position of the pole climbing device on the pole body, or enables quick removal of the pole climbing device from the pole body and installation of the pole climbing device onto the pole body.

[0026] Please see Figure 1 , Figure 1 A pole climbing device is provided as an embodiment of the present invention.
[0027] The present invention provides a pole climbing device, comprising: a first clamp 1, a second clamp 2, a foot pedal assembly 3, a locking component 4, and an unlocking component 5;
[0028] One end of the first clamp 1 is rotatably connected to one end of the second clamp 2, and the other end of the first clamp 1 is connected to the foot pedal assembly 3; the first clamp 1 is provided with a first contact rod 11, and the second clamp 2 is provided with a second contact rod 21. The first contact rod 11 and the second contact rod 21 are used to contact the rod on opposite sides of the rod body respectively.
[0029] The foot pedal assembly 3 is located on one side of the first contact rod portion 11 and is away from the contact rod end face of the first contact rod portion 11;
[0030] The locking member 4 is located at the rotation point between the first clamp 1 and the second clamp 2, and is used to control the second clamp 2 to rotate unidirectionally around the first clamp 1, and to lock in the opposite direction, so that the first clamp 1 and the second clamp 2 clamp the rod.
[0031] The unlocking component 5 is connected to the locking component 4. The unlocking component 5 is used to unlock the locking component 4, so that the second clamp 2 can rotate bidirectionally around the first clamp 1.
[0032] It is understood that in this embodiment, the foot pedal assembly 3 receives a downward force from the foot, which is transmitted to the first clamp 1 and the second clamp 2 through the lever principle, causing the first clamp 1 and the second clamp 2 to clamp the pole together. When the pedal is not subjected to the force of the foot, the second clamp 2 and the first clamp 1 are not subjected to any force, and the pole will be released. Therefore, in the specific implementation process, the pole climbing device in this embodiment is installed on the left leg and the right leg respectively. When one leg provides a downward force to the foot pedal assembly 3, the corresponding pole climbing device clamps the pole, and the other leg does not need to provide a downward force to the pedal, so there is no looseness between the pole climbing device and the pole. At this time, the other leg moves up or down along the pole, and the left and right legs alternately apply force according to the above process to achieve pole climbing. In this embodiment, the pole is a utility pole.
[0033] It should be further explained that in this embodiment, a lever is formed by the foot pedal assembly 3, the first clamp 1, and the second clamp 2; the foot pedal assembly 3 is the power arm, the first contact rod 11 is the fulcrum, and the part composed of the first clamp 1 and the second clamp 2 located between the first contact rod 11 and the second contact rod 21 is the resistance arm; when the foot pedal assembly 3 is subjected to a downward force, the first contact rod 11 contacts the rod body and generates a squeezing friction force, the second clamp 2 is subjected to an upward force and generates a tendency to rotate around the first contact rod 11, so that the second contact rod 21 contacts the rod body and generates a squeezing friction force. Therefore, by generating a squeezing friction force on the rod body on the opposite sides of the rod body through the first clamp 1 and the second clamp 2, the first clamp 1 and the second clamp 2 clamp the rod body.
[0034] It should be further explained that in this embodiment, the locking member 4 controls the second clamp 2 to rotate unidirectionally around the first clamp 1, so that the first clamp 1 and the second clamp 2 clamp the pole. The angle between the first clamp 1 and the second clamp 2 can be adjusted according to the diameter of the pole, which can adapt to different diameters of the pole. By locking in the opposite direction, the second clamp 2 is prevented from turning back and loosening during the climbing process, ensuring the safety of the pole climbing operation. The unlocking member 5 unlocks the locking member 4 to realize the bidirectional rotation of the second clamp 2, which facilitates the quick adjustment of the position of the pole climbing device on the pole, or realizes the quick removal of the pole climbing device from the pole and the installation of the pole climbing device on the pole.
[0035] In a more specific embodiment, such as Figure 3 As shown, the locking member 4 includes a ratchet 41 and a pawl 42. The ratchet 41 is fixedly connected to the rotating end of the second clamping member 2, and the pawl 42 is fixedly connected to the rotating end of the first clamping member 1. The pawl 42 is located on one side of the ratchet 41 and contacts the ratchet 41. It can be understood that, in specific implementation, the contact between the pawl 42 and the ratchet 41 enables the second clamping member 2 to rotate unidirectionally around the first clamping member 1, thus locking in the opposite direction.
[0036] In a more specific embodiment, one end of the first clamp 1 and one end of the second clamp 2 are connected by a rotating structure 6. The rotating structure 6 includes a column 61 and a collar 62. The column 61 is connected to the second clamp 2 and is fixedly connected to and coaxially arranged with a ratchet 41. The collar 62 is connected to the end of the first clamp 1 and is sleeved on the column 61 to achieve a rotatable connection between the first clamp 1 and the second clamp 2. It is understood that, in specific implementations, the column 61 is provided with a locking position for placing the collar 62, so that the collar 62 will not fall off the column 61 while rotating relative to it. The rotatable connection between the first clamp 1 and the second clamp 2 is achieved through the cooperation of the collar 62 and the column 61.
[0037] It should be noted that, since the pawl 42 is fixedly connected to the first clamp 1, and the column 61 is fixedly connected to the ratchet 41 and coaxially arranged, with the pawl 42 located on one side of the ratchet 41, when the pawl 42 contacts the ratchet 41, under the constraint of the ratchet 41 and the pawl 42, the second clamp 2 can only rotate unidirectionally around the column 61 towards the first contact rod 11 of the first clamp 1, and cannot rotate in the opposite direction. In the specific implementation, the second clamp 2 is rotated unidirectionally by swinging the climbing device with the feet. During the climbing process, the legs are swung towards the pole, which allows the second clamp 2 to rotate unidirectionally, reducing the angle between the second clamp 2 and the first clamp 1 until it adapts to the diameter of the pole. Furthermore, through the reverse locking function of the ratchet 41 and the pawl 42, the first clamp 1 and the second clamp 2 are automatically locked, eliminating the need for manual adjustment and manual fixing. Furthermore, existing manual adjustment and fixing methods rely on guesswork to determine the angle between the first clamp 1 and the second clamp 2. If the guess is inaccurate, at best, readjustment is required, and at worst, a fall and injury may occur. This embodiment utilizes a ratchet 41 and a pawl 42 to achieve unidirectional movement of the second clamp 2 by swinging the foot. The first clamp 1 and the second clamp 2 automatically clamp the pole body, automatically adapting to gradually thinning poles, eliminating the need for guesswork and significantly improving the accuracy and efficiency of adjusting the angle between the first clamp 1 and the second clamp 2.
[0038] In a more specific embodiment, such as Figure 1-2 As shown, the unlocking component 5 includes an adjusting rod 51, an elastic element 52, and a telescopic component 53. The pawl 42 is fixedly connected to the adjusting rod 51. The middle part of the adjusting rod 51 is rotatably connected to the first clamp 1. One end of the adjusting rod 51 is connected to one end of the elastic element 52. The other end of the elastic element 52 is fixedly connected to the first clamp 1 by a screw. The other end of the adjusting rod 51 is connected to the telescopic component 53. When the elastic element 52 is retracted, the elastic element 52 is stretched, and the adjusting rod 51 rotates around its middle part to disengage the pawl 42 from the ratchet 41. When the elastic element 52 is restored, the adjusting rod 51 rotates around its middle part, and the telescopic component 53 extends, allowing the pawl 42 to contact the ratchet 41.
[0039] Understandably, in practice, when the telescopic member 53 retracts, the elastic member 52 is stretched, the adjusting rod 51 rotates around its middle part, and the adjusting rod 51 tilts towards the telescopic member 53, causing the pawl 42 to disengage from the ratchet 41, thus unlocking the ratchet 41. The column 61 and the collar 62 can rotate freely relative to each other, that is, the second clamp 2 can rotate bidirectionally around the first clamp 1. When the telescopic member 53 extends, the spring returns to its original position, the adjusting rod 51 rotates around its middle part, and returns to its original position towards the elastic member 52, causing the ratchet 41 to contact the ratchet 41.
[0040] In a more specific embodiment, the elastic element 52 is a spring, which has good elasticity and self-adjustment ability. Its deformation and recovery are rapid, which helps to improve the unlocking efficiency of the unlocking element 5 in this embodiment.
[0041] In a more specific embodiment, the telescopic member 53 includes a fixed tube 531 and a strip 532. The fixed tube 531 is fixed to the first clamp 1. The strip 532 passes through the interior of the fixed tube 531 and is movably connected to the fixed tube 531. One end of the strip 532 is exposed outside the fixed tube 531 and connected to the adjusting rod 51. The other end of the strip 532 is connected to the puller 533, and the puller 533 abuts against the end of the fixed tube 531.
[0042] Understandably, in practice, by pulling the puller 533, the strip 532 moves relative to the fixed tube 531. When the distance between the puller 533 and the end of the fixed tube 531 increases, the distance between the adjusting rod 51 and the fixed tube 531 decreases, causing the telescopic member 53 to retract. This causes the adjusting rod 51 to tilt towards the fixed tube 531, and the spring is stretched. At this time, the pawl 42 disengages from the ratchet 41. When the puller 533 is stopped and the puller 533 is released, the spring loses its force and returns to its original position, causing the adjusting rod 51 to return to the starting position. This increases the distance between the adjusting rod 51 and the fixed tube 531 back to its initial state. At the same time, the strip 532 moves relative to the fixed tube 531 as the adjusting rod 51 returns to its original position, causing the puller 533 to reset. At this time, the pawl 42 remains in contact with the ratchet 41. Therefore, in this embodiment, as long as the puller 533 is not moved, the pawl 42 and the ratchet 41 can be kept in contact, preventing the second clamp 2 from rotating in the opposite direction. Even after the puller 533 is moved, the pawl 42 and the ratchet 41 can quickly return to contact under the rapid restoring action of the spring. Therefore, the unlocking member 5 in this embodiment has high control sensitivity and strong safety performance.
[0043] In a more specific embodiment, the strip 532 is a steel wire. It is understood that, in practice, the steel wire has high strength and good flexibility, and a long service life.
[0044] In a more specific embodiment, the puller 533 includes a first frustum 5331 and a second frustum 5332. Both the first frustum 5331 and the second frustum 5332 are provided with axially arranged through holes. The strip 532 passes through the through holes. The larger diameter end of the first frustum 5331 is fixedly connected to the end of the fixed tube 531. The larger diameter end of the second frustum 5332 is fixedly connected to the end of the strip 532. The smaller diameter end of the first frustum 5331 abuts against the smaller diameter end of the second frustum 5332.
[0045] It is understandable that the distance between the second frustum 5332 and the first frustum 5331 is adjusted by controlling the distance between them. The inclined surface of the frustum is designed to fit the hand better, facilitating one-handed operation. In practice, the rear finger presses against the inclined surface of the second frustum 5332, while the front finger pushes the inclined surface of the first frustum 5331. This increases the distance between the second frustum 5332 and the first frustum 5331, thus increasing the distance between the second frustum 5332 and the end of the fixed tube 531. The strip 532 moves within the fixed tube 531 along with the second frustum 5332, decreasing the distance between the adjusting rod 51 and the fixed tube 531, thereby unlocking. Therefore, this example, through the design of the first frustum 5331 and the second frustum 5332, makes the unlocking operation of the unlocking component 5 more convenient and faster.
[0046] In a more specific embodiment, the end of the strip 532 connected to the second frustum 5332 is provided with an anti-detachment member 534, which abuts against the second frustum 5332 to prevent the second frustum from falling off from the end of the strip 532.
[0047] In a more specific embodiment, the contact rod end faces of the first contact rod portion 11 and the second contact rod portion 21 are provided with rubber. It is understood that, in practical implementation, rubber has good elasticity and flexibility. By using rubber in contact with the rod body, it can adaptively deform according to the shape of the contact surface, fitting more tightly with the rod body surface, increasing the actual contact area, and improving the frictional force between the first contact rod portion 11 and the second contact rod portion 21 and the rod body surface.
[0048] In a more specific embodiment, the foot pedal assembly 3 is higher or lower than the first contact rod portion 11. It is understandable that traditional utility pole climbing devices (such as Zhang Kejin's iron shoes from 1960) require hooking a ring onto a slightly higher pole on the opposite side and securing it with a fulcrum, while simultaneously exerting outward and downward force to achieve stability. When people are afraid, they tend to approach and hug the pole, inevitably leading to falls and injuries. This device aligns with conventional human thinking, allowing users to approach and hug the pole, and exert downward force to obtain stable support. Compared to existing technologies where the foot pedal assembly 3 is positioned next to the first contact rod portion 11, by positioning the foot pedal assembly 3 higher or lower than the first contact rod portion 11, the power arm between the first contact rod portion 11 and the foot pedal assembly 3 is extended without widening the distance between the foot and the pole. A larger power arm requires less effort. Furthermore, when the foot applies a downward force to the pedal assembly 3, the pedal assembly 3 tends to rotate around the first contact rod 11 and approach the rod body. This causes the first contact rod 11 of the first clamp 1 and the second contact rod 21 of the second clamp 2 to press against the surface of the rod body, thus achieving clamping of the rod body by the first clamp 1 and the second clamp 2. This eliminates the need for the foot to apply a tilting force to the pedal assembly 3, reducing the difficulty of applying force with the foot.
[0049] In a more specific embodiment, a vertical rod 10 is provided at the connection end between the first clamp 1 and the foot pedal assembly 3. The top of the vertical rod 10 is connected to the first clamp 1, the bottom of the vertical rod 10 is connected to the foot pedal assembly 3, and the first contact rod portion 11 is provided in the middle or at the top of the vertical rod 10.
[0050] Understandably, in specific implementation, the foot pedal is connected to the first clamp 1 via the vertical rod 10. The foot pedal is located at the bottom of the vertical rod 10, and the first contact rod 11 is located in the middle and bottom of the vertical rod 10, so that the foot pedal is lower than the first contact rod 11. In this embodiment, the first contact rod 11 is located on one side of the middle of the lower leg. When the weight of the person is added to the foot pedal assembly 3 at the lower position, a lever force effect is formed, which makes the climbing device more firmly fixed on the pole body. Moreover, the foot pedal assembly 3 can be pressed down with greater force to strengthen this fixing effect, thus overcoming the defect of traditional devices that will aggravate slippage and cause workers to fall when pedaling down.
[0051] In a more specific embodiment, the foot pedal assembly 3 is a foot pedal.
[0052] In a more specific embodiment, a rotation adjustment member is provided between the first contact rod 11 and the vertical rod 10. Since the first contact rod 11 is mounted on the vertical rod 10, the first contact rod 11 can be rotated and adjusted around the vertical rod 10 so that the first contact rod 11 is in a more accurate relative position with the second contact rod 21.
[0053] In a more specific embodiment, the second clamp 2 is an arc-shaped rod, the second contact rod portion 21 is an arc-shaped rubber, and the part of the first contact rod portion 11 that contacts the rod body is also an arc-shaped rubber, which can better fit the rod body.
[0054] In a more specific embodiment, a foot fixing component is also included, which includes a first fixing strap 31, a second fixing strap 32, and a third fixing strap 33. The first fixing strap 31 is disposed on the foot pedal assembly 3 and is used to fix the foot pedal assembly 3 to the middle of the foot. The second fixing strap 32 and the third fixing strap 33 are both disposed on the vertical bar 10. The second fixing strap 32 is used to fix the ankle, and the third fixing strap 33 is used to fix the lower leg.
[0055] Understandably, in practice, the first fixing strap 31 connects the foot pedal to the middle of the foot, providing greater stability compared to the existing technology that connects to the forefoot, making prolonged standing work more comfortable and ergonomic. The second fixing strap 32 and the third fixing strap 33 strengthen the connection between the leg and the device, making it less likely for the leg to detach from the device and improving safety.
[0056] The working principle of the pole climbing device in this embodiment is as follows:
[0057] The middle of the foot is fixed to the foot pedal by the first fixing strap 31, the ankle is fixed to the vertical bar 10 by the second fixing strap 32, and the leg is fixed to the vertical bar 10 by the third fixing strap 33.
[0058] The first contact rod 11 located on the vertical rod 10 abuts against the rod body, and the first contact rod 11 is made to fit by rotating the adjusting member;
[0059] The leg drives the first clamp 1 to swing closer to the rod, causing the second clamp 2 to rotate in one direction until the second contact rod 21 on the second clamp 2 contacts the rod.
[0060] When the foot exerts a downward force on the pedal, under the action of the lever principle, the first contact rod 11 of the first clamp 1 acts as the fulcrum of the lever. The first contact rod presses against the surface of the rod body to generate friction. The second rod body generates an upward force and tends to rotate around the first contact rod 11, so that the second contact rod 21 of the second clamp 2 presses against the surface of the other side of the rod body to generate friction. At this time, the first clamp 1 and the second clamp 2 clamp the rod body.
[0061] When the foot releases the downward force on the foot pedal, the first clamp 1 and the second clamp 2 loosen between themselves and the pole, allowing the pole climbing device to move up and down.
[0062] When the second frustum 5332 is manually pulled away from the first frustum 5331, the distance between the second frustum 5332 and the end of the fixed tube 531 increases, the strip 532 moves relative to the fixed tube 531, the strip 532 drives one end of the adjusting rod 51 to rotate closer to the fixed tube 531, the spring connected to the other end of the adjusting rod 51 is stretched, the adjusting rod 51 drives the pawl 42 to disengage from the ratchet 41, and the second clamp 2 can rotate bidirectionally around the first clamp rod;
[0063] When the hand releases the second frustum 5332, the spring loses its force and returns to its original position, causing the adjusting rod 51 to return to the center. The adjusting rod 51 then causes the pawl 42 to re-engage with the ratchet 41, and the second clamp 2 rotates unidirectionally around the first clamp 1. The second frustum 5332 then re-engages with the first frustum 5331.
[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
