[0026] See also Figure 1 , Figure 1 A pole climbing device is provided in 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 footrest assembly 3, a locking member 4 and an unlocking member 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 pedal assembly 3; the first clamp 1 is provided with a first rod-touching portion 11, and the second clamp 2 is provided with a second rod-touching portion 21, and the first rod-touching portion 11 and the second rod-touching portion 21 are used to contact the rod at opposite sides of the rod body respectively;

[0029] The pedal assembly 3 is disposed on one side of the first contact rod portion 11 and faces away from the contact rod end surface of the first contact rod portion 11;

[0030] The locking member 4 is arranged at the rotation position between the first clamping member 1 and the second clamping member 2, and is used to control the second clamping member 2 to rotate unidirectionally around the first clamping member 1, and to lock the reverse rotation, so that the first clamping member 1 and the second clamping member 2 clamp the rod body;

[0031] The unlocking member 5 is connected to the locking member 4 , and the unlocking member 5 is used to unlock the locking member 4 , so that the second clamping member 2 can rotate bidirectionally around the first clamping member 1 .

[0032] It can be understood that the present embodiment is subjected to the downward force of the foot through the pedal assembly 3, and the force is transmitted to the first clamp 1 and the second clamp 2 through the lever principle, so that the first clamp 1 and the second clamp 2 clamp the rod body under the joint action; when the pedal is not subjected to the action of the foot, the second clamp 2 and the first clamp 1 are not subjected to the force, and the rod body will be loosened. Therefore, in the specific implementation process, the pole climbing device of the present embodiment is respectively installed on the left leg and the right leg. When the pedal assembly 3 of one leg provides a downward force, the corresponding pole climbing device clamps the rod body, and the other leg does not need to provide a downward force to the pedal, so that there is looseness between the pole climbing device and the rod body. At this time, the other leg moves up or down along the rod body, and the left and right legs apply force alternately according to the above process to achieve pole climbing. Among them, the pole body of the present embodiment is a telephone pole.

[0033] It should be further explained that, in this embodiment, a lever is formed by the pedal assembly 3, the first clamp 1, and the second clamp 2; the pedal assembly 3 is a power arm, the first touch rod portion 11 is a fulcrum, and the portion consisting of the first clamp 1 and the second clamp 2 located between the first touch rod portion 11 and the second touch rod portion 21 is a resistance arm; when the pedal assembly 3 is subjected to a downward force, the first touch rod portion 11 contacts the rod body and generates a squeezing friction force, and the second clamp 2 is subjected to an upward force and generates a movement tendency to rotate around the first touch rod portion 11, so that the second touch rod portion 21 contacts the rod body and generates a squeezing friction force. Therefore, the squeezing friction force on the rod body is generated on the opposite sides of the rod body by the first clamp 1 and the second clamp 2, so that the first clamp 1 and the second clamp 2 clamp the rod body.

[0034] It needs to be further explained that, in this embodiment, the locking member 4 is used to control 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 rod body, and the angle between the first clamp 1 and the second clamp 2 can be adjusted according to the diameter of the rod body, so as to adapt to different diameters of the rod body; by locking in reverse rotation, the second clamp 2 can be prevented from reversing and loosening during the climbing process, thereby ensuring the safety of the pole climbing operation; by unlocking the locking member 4 through the unlocking member 5, the second clamp 2 can be rotated in both directions, which is convenient for quickly adjusting the position of the pole climbing device on the pole body, or realizing the quick removal of the pole climbing device from the pole body and the installation of the pole climbing device on the pole body.

[0035] In a more specific embodiment, 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 clamp 2, the pawl 42 is fixedly connected to the rotating end of the first clamp 1, the pawl 42 is located on one side of the ratchet 41, and the pawl 42 contacts the ratchet 41. It can be understood that in a specific implementation, the pawl 42 contacts the ratchet 41 to achieve unidirectional rotation of the second clamp 2 around the first clamp 1 and reverse locking.

[0036] In a more specific embodiment, one end of the first clamp 1 is connected to one end of the second clamp 2 via 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, the column 61 is fixedly connected to the ratchet 41 and coaxially arranged, the collar 62 is connected to the end of the first clamp 1, and the collar 62 is sleeved on the column 61 to realize the rotational connection between the first clamp 1 and the second clamp 2. It can be understood that in a specific implementation, a position is provided on the column 61 for placing the collar 62, so that the collar 62 will not fall off the column 61 while rotating relative to the column 61. The rotational connection between the first clamp 1 and the second clamp 2 is realized by the cooperation between 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, the column 61 is fixedly connected to the ratchet 41 and is coaxially arranged, and the pawl 42 is arranged on one side of the ratchet 41, when the pawl 42 contacts the ratchet 41, under the limiting effect of the ratchet 41 and the pawl 42, the second clamp 2 can only rotate unidirectionally around the column 61 toward the first contact rod portion 11 close to the first clamp 1, and cannot rotate in the opposite direction. In the specific implementation process, the second clamp 2 is rotated unidirectionally by swinging the pole climbing device with the feet. In the process of climbing the pole, the legs are swung toward the pole body, which can make the second clamp 2 rotate unidirectionally, and the angle between the second clamp 2 and the first clamp 1 becomes smaller until it adapts to the diameter of the pole body, and the reverse locking function of the ratchet 41 and the pawl 42 is used to realize the automatic locking of the first clamp 1 and the second clamp 2, without the need for manual adjustment and manual fixation. In addition, in the existing manual adjustment and manual fixing methods, the method of determining how much to adjust the angle between the first clamp 1 and the second clamp 2 is based on guessing. If the guess is wrong, the user may have to adjust it again at best, or even fall and get injured at worst. The present embodiment uses the ratchet 41 and the pawl 42 to control the 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 and automatically adapt to gradually tapering poles without guessing, which significantly improves the accuracy and efficiency of the angle adjustment between the first clamp 1 and the second clamp 2.

[0038] In a more specific embodiment, Figure 1-2 As shown, the unlocking member 5 includes an adjusting rod 51, an elastic member 52 and a telescopic member 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 clamping member 1, one end of the adjusting rod 51 is connected to one end of the elastic member 52, the other end of the elastic member 52 is fixedly connected to the first clamping member 1 through a screw, and the other end of the adjusting rod 51 is connected to the telescopic member 53; the telescopic member 53 is used for the elastic member 52 to be stretched when contracting, and the adjusting rod 51 rotates around its middle to disengage the pawl 42 from the ratchet 41; the telescopic member 53 is used for the adjusting rod 51 to rotate around its middle when the elastic member 52 recovers, and the telescopic member 53 extends to make the pawl 42 contact the ratchet 41.

[0039] It can be understood that, in a specific implementation, the telescopic member 53 contracts, the elastic member 52 is stretched, the adjusting rod 51 rotates around its center, and the adjusting rod 51 tilts toward the telescopic member 53, driving the pawl 42 to disengage from the ratchet 41, thereby unlocking the ratchet 41, and the column 61 and the ring 62 can rotate freely relative to each other, that is, the second clamp 2 can rotate bidirectionally around the first clamp 1; the telescopic member 53 extends, the spring recovers, the adjusting rod 51 rotates around its center, and returns to the direction of the elastic member 52, driving the ratchet 41 to contact the ratchet 41.

[0040] In a more specific embodiment, the elastic member 52 is a spring. The spring has good elasticity and automatic adjustment ability, and its deformation and recovery changes are rapid, which helps to improve the unlocking efficiency of the unlocking member 5 of this embodiment.

[0041] In a more specific embodiment, the telescopic member 53 includes a fixed tube 531 and a strip member 532. The fixed tube 531 is fixed on the first clamp 1. The strip member 532 passes through the interior of the fixed tube 531 and is movably connected to the fixed tube 531. One end of the strip member 532 is exposed outside the fixed tube 531 and connected to the adjusting rod 51. The other end of the strip member 532 is connected to the puller 533, and the puller 533 abuts against the end of the fixed tube 531.

[0042] It can be understood that, in a specific implementation, by pulling the puller 533, the strip member 532 is caused to move 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, so that the telescopic member 53 contracts, driving the adjusting rod 51 to tilt toward the fixed tube 531, and at the same time the spring is stretched, at which time the pawl 42 disengages from the ratchet 41; when the pulling of the puller 533 is stopped and the puller 533 is released by hand, the spring loses its force and recovers by itself, driving the adjusting rod 51 to return to the original state, so that the distance between the adjusting rod 51 and the fixed tube 531 increases to the initial state, and at the same time the strip member 532 moves relative to the fixed tube 531 as the adjusting rod 51 returns to the original state, driving the puller 533 to reset, at which time the pawl 42 and the ratchet 41 remain in contact. Therefore, in this embodiment, as long as the puller 533 is not moved, the pawl 42 and the ratchet 41 can be ensured to maintain contact, thereby 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 be quickly restored to contact due to the rapid recovery action of the spring. Therefore, the unlocking member 5 of 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 understandable that, in a specific implementation, 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 member 5331 and a second frustum member 5332. The first frustum member 5331 and the second frustum member 5332 are both axially provided with a through hole, and the strip member 532 passes through the through hole. The larger diameter end of the first frustum member 5331 is fixedly connected to the end of the fixed tube 531, the larger diameter end of the second frustum member 5332 is fixedly connected to the end of the strip member 532, and the smaller diameter end of the first frustum member 5331 is abutted against the smaller diameter end of the second frustum member 5332.

[0045] It is understandable that the distance between the second truncated table 5332 and the first truncated table 5331 is controlled to adjust the distance between the second truncated table and the fixed tube 531. Based on the inclined surface of the truncated table, it is more suitable for hand design and convenient for one-hand operation. In specific implementation, the rear finger supports the inclined surface of the second truncated table 5332, and the front finger pushes the inclined surface of the first truncated table 5331, so that the distance between the second truncated table 5332 and the first truncated table 5331 can be increased, and the distance between the second truncated table 5332 and the end of the fixed tube 531 can be increased. The strip 532 moves with the second truncated table 5332 in the fixed tube 531, and the distance between the adjustment rod 51 and the fixed tube 531 is reduced, so as to achieve unlocking. Therefore, this example makes the unlocking operation of the unlocking member 5 more convenient and quick through the design of the first truncated table 5331 and the second truncated table 5332.

[0046] In a more specific embodiment, an anti-dropout piece 534 is provided at the end of the strip member 532 connected to the second truncated table member 5332 , and the anti-dropout piece 534 presses against the second truncated table member 5332 to prevent the second original table member from falling off from the end of the strip member 532 .

[0047] In a more specific embodiment, rubber is provided on the end surfaces of the first touch rod portion 11 and the second touch rod portion 21. It is understandable that, in a specific implementation, the rubber has good elasticity and flexibility, and when the rubber contacts the rod body, it can be adaptively deformed according to the shape of the contact surface, and fit more closely with the surface of the rod body, thereby increasing the actual contact area and improving the friction between the first touch rod portion 11 and the second touch rod portion 21 and the surface of the rod body.

[0048] In a more specific embodiment, the pedal assembly 3 is higher or lower than the first pole-touching portion 11. It is understandable that the traditional pole climbing device (Zhang Kejin's iron shoes in 1960) needs to hook the higher pole on the opposite side through a ring, and then clamp it with a fulcrum, and at the same time, the body needs to exert force outward and downward to fix it. When people are afraid, they are more willing to get close to and hold the pole tightly, which will inevitably cause them to fall and get injured. The use skills do not conform to conventional thinking and are prone to falling and getting injured; this device conforms to conventional human thinking, and can get close to and hold the pole tightly, and apply force downward to obtain a fixed support force. Compared with the prior art in which the pedal assembly 3 is set next to the first pole-touching portion 11, by having the pedal assembly 3 higher or lower than the first pole-touching portion 11, the power arm between the first pole-touching portion 11 and the pedal assembly 3 is extended without widening the distance between the foot and the pole body. The larger the power arm, the more labor-saving it is. When the foot exerts a downward force on the pedal assembly 3, the pedal assembly 3 can have a tendency to rotate around the first touch rod portion 11 close to the rod body, thereby causing the first touch rod portion 11 of the first clamp 1 and the second touch rod portion 21 of the second clamp 2 to press the surface of the rod body, thereby achieving the first clamp 1 and the second clamp 2 clamping the rod body, without the foot applying a tilting force on the pedal assembly 3, thereby reducing the difficulty of applying force with the foot.

[0049] In a more specific embodiment, a vertical rod 10 is provided at the connecting end of the first clamp 1 and the 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 pedal assembly 3, and the first contact rod portion 11 is provided in the middle or top of the vertical rod 10.

[0050] It can be understood that, in a specific implementation, the foot pedal is connected to the first clamp 1 through the vertical rod 10, the foot pedal is arranged at the bottom of the vertical rod 10, and the first touch rod portion 11 is arranged at the middle and bottom of the vertical rod 10, so that the foot pedal is lower than the first touch rod portion 11; the first touch rod portion 11 of this embodiment is located on one side of the middle of the calf, and when the weight of a person is added to the foot pedal assembly 3 at a lower position, a lever force effect is formed to fix the pole climbing device more firmly on the pole body, and the foot pedal assembly 3 can be pressed down with greater force to enhance the fixing effect, thereby overcoming the defect that the traditional device will aggravate the slipping phenomenon and cause the worker to fall when pedaling down.

[0051] In a more specific embodiment, the footrest assembly 3 is a foot pedal.

[0052] In a more specific embodiment, a rotation adjustment member is provided between the first touch rod portion 11 and the vertical rod 10. By setting the first touch rod portion 11 on the vertical rod 10, the first touch rod portion 11 can be rotated and adjusted around the vertical rod 10, so that the first touch rod portion 11 is in a more accurate relative position with the second touch rod portion 21.

[0053] In a more specific embodiment, the second clamp 2 is an arc-shaped rod, the second rod-touching portion 21 is an arc-shaped rubber, and the portion of the first rod-touching 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 assembly is also included, and the foot fixing assembly includes a first fixing strap 31, a second fixing strap 32 and a third fixing strap 33. The first fixing strap 31 is set on the footrest assembly 3, and the first fixing strap 31 is used to fix the footrest assembly 3 to the middle part of the sole of the foot. The second fixing strap 32 and the third fixing strap 33 are both set on the vertical rod 10, and the second fixing strap 32 is used to fix the ankle, and the third fixing strap 33 is used to fix the calf.

[0055] It is understandable that, in specific implementation, the first fixing belt 31 is used to connect the footrest to the middle of the sole, which is more stable than the connection with the forefoot in the prior art, making long-term standing work more comfortable and more ergonomic. The second fixing belt 32 and the third fixing belt 33 strengthen the connection between the leg and the device, making it difficult for the leg to detach from the device, thereby improving safety.

[0056] The working principle of a pole climbing device in this embodiment is as follows:

[0057] The middle part of the sole is fixed to the footrest by a first fixing belt 31, the ankle is fixed to the vertical rod 10 by a second fixing belt 32, and the leg is fixed to the vertical rod 10 by a third fixing belt 33;

[0058] The first contact rod portion 11 on the vertical rod 10 is brought into contact with the rod body, and the first contact rod portion 11 is made to fit by rotating the adjusting member;

[0059] The legs drive the first clamp 1 to swing closer to the rod body, so that the second clamp 2 rotates in one direction until the second rod-touching portion 21 on the second clamp 2 contacts the rod body;

[0060] When the foot exerts a downward force on the pedal, under the action of the lever principle, the first contact rod portion 11 of the first clamp 1 acts as a lever fulcrum, the first contact rod squeezes the surface of the rod body to generate friction, the second rod body generates an upward force and has a tendency to rotate around the first contact rod portion 11, so that the second contact rod portion 21 of the second clamp 2 squeezes the surface of the other side of the rod body to generate friction, and at this time the first clamp 1 and the second clamp 2 clamp the rod body;

[0061] When the foot stops exerting downward force on the pedal, the first clamp 1, the second clamp 2 and the pole body become loose, so that the pole climbing device can move up and down;

[0062] When the second truncated table member 5332 is manually pulled away from the first truncated table member 5331, the distance between the second truncated table member 5332 and the end of the fixed tube 531 increases, and the strip member 532 moves relatively in the fixed tube 531. The strip member 532 drives one end of the adjusting rod 51 to rotate toward the fixed tube 531, and the spring connected to the other end of the adjusting rod 51 is stretched, and the adjusting rod 51 drives the pawl 42 to disengage from the ratchet 41, so that the second clamping member 2 can rotate bidirectionally around the first clamping rod.

[0063] When the hand releases the second truncated table member 5332, the spring loses its force and recovers, driving the adjusting rod 51 to return to the normal position.
