Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to a power climbing device with a fall protection structure and its usage method. Background Technology

[0002] During power construction, workers often need to use pole climbing hooks to climb utility poles. During the climb, workers need to hold the pole tightly with both hands and lift one foot so that the pole climbing hook is released from its original position and rises with the foot. Then, the workers move their hands up to move the entire worker up.

[0003] However, the existing climbing method using foot catches poses significant safety hazards and requires experienced personnel to use. Current foot catches are generally semi-circular, with the open end used to engage the pole. Novice workers are prone to accidentally detaching the foot catch from the pole or slipping off, causing falls and delays in the project schedule. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an electric climbing device with a fall protection structure and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The ring seat includes a first arc plate and a second arc plate for surrounding the wire rod. The first arc plate and the second arc plate are rotatably connected to both ends of the mounting base. A positioning component is provided at the end of the first arc plate and the second arc plate away from the mounting base.

[0011] Preferably, a first pull rope is fixedly provided on the positioning block. The end of the first pull rope away from the positioning block passes through the positioning rod, the groove, and the movable groove in sequence and is fixedly connected to the first arc plate. The first arc plate and the guide plate connected thereto have sliding grooves for the movement of the first pull rope. A second rotating shaft is also fixedly provided on the guide plate. A force plate is provided on the second rotating shaft. A second torsion spring is sleeved on the second rotating shaft. A pressure block that moves against the first pull rope is fixedly provided on the force plate of the first arc plate.

[0012] Preferably, the abutting mechanism includes a swing groove formed on the mounting base, a third rotating shaft rotatably connected in the swing groove, a swing rod fixed on the third rotating shaft, a third torsion spring with its two ends respectively connected to the mounting base and the swing rod, and a pedal and a first abutting plate respectively connected to the two ends of the swing rod.

[0013] Preferably, the pedal and the swing arm are inclined, the heel position of the pedal is lower than the toe position, and the pedal is provided with straps for binding the feet.

[0014] Preferably, the abutting mechanism further includes support plates fixedly mounted on the first and second arc plates, with a second pull rope slidably connected within each support plate. A fourth rotating shaft is rotatably mounted on both the first and second arc plates, and an elastic telescopic plate is fixedly mounted on the fourth rotating shaft. The fixed end of the elastic telescopic plate is fixedly connected to the fourth rotating shaft, and the telescopic end of the elastic telescopic plate is connected to a second abutting plate. The end of the elastic telescopic plate away from the second abutting plate is fixedly connected to one end of the second pull rope. The end of the second pull rope away from the elastic telescopic plate passes through the support plate and the mounting base and is connected to the lower side of the swing rod.

[0015] Preferably, the second abutment plate is provided with a sliding groove, a sliding block is slidably connected in the sliding groove, a third elastic element is provided between the sliding block and the inner wall of the sliding groove, the sliding block is movably connected to the end of the elastic telescopic plate away from the second pull rope by a pin, and a grounding plate is provided at the bottom of the second abutment plate by a connecting block.

[0016] Preferably, both the second abutment plate and the first abutment plate are provided with an installation sleeve. One end of the installation sleeve is provided with an anti-slip surface, and the anti-slip surface is provided with a plurality of sharp protrusions. An installation hole is opened on the side of the installation sleeve away from the anti-slip surface, and a bolt is movably connected in the installation hole.

[0017] This invention also discloses a method of using an electric climbing device with a fall protection structure, comprising the following steps:

[0018] S1: When workers climb the pole, they first tie their feet to the footboard with straps, and then their feet move towards the pole by moving the ring seat through the mounting bracket.

[0019] S2: Place the rod between the two guide plates, then make the annular seat continue to move closer to the rod and abut against it. The force plate on the guide plate first abuts against the outer wall of the rod. The force plate weakens the impact force of the annular seat on the rod. The force plate fits against the guide plate with the second rotating shaft as the center. The pressure block on the force plate presses against the first pull rope. The first pull rope is forced to retract the positioning block into the groove. Then the first pull rope transmits the force to the positioning rod, causing the positioning rod to retract into the movable groove. The first elastic element and the second elastic element are both compressed, and the first arc plate and the second arc plate are no longer restricted.

[0020] S3: As the first and second arc plates continue to move toward the pole position, the ends of the first and second arc plates away from the mounting base separate from each other and provide space for the pole to enter. The ring seat continues to move toward the pole until the pole is completely enclosed within the area formed by the first and second arc plates. At this time, the force plate is no longer under force, and the positioning rod drives the positioning block to reset, so that the first and second arc plates are inserted.

[0021] S4: After the ring seats on both feet surround the line pole, the height of the heels of both feet is lower than the toes. The pedal drives the first abutment plate to flip through the swing rod. When the swing rod flips, it drives the second pull rope to move. The second pull rope pulls down the upper end of the elastic telescopic plate, causing the elastic telescopic plate to deflect around the fourth pivot. The elastic telescopic plate drives the second abutment plate to abut against the two sides of the line pole, increasing the contact area between the ring seat and the line pole. Before the first abutment plate abuts against the outer wall of the line pole, the second abutment plate has already abutted against the line pole. The elastic telescopic plate begins to contract and drives the sliding block to move upward in the sliding groove to ensure that the swing rod pulls the second pull rope normally. After the first abutment plate abuts against the side wall of the line pole, the positioning work of the ring seat and the line pole is completed.

[0022] S5: When starting the climbing work, the worker first raises one foot so that the heel is higher than the toes. The swinging rod drives the first abutment plate to return to its original position and rotate. The first abutment plate no longer abuts against the pole. At the same time, the second pull rope no longer pulls down the elastic telescopic plate. The second abutment plate returns to its original position. At this time, the moving resistance between the ring seat and the pole is reduced. After the raised foot drives the ring seat to move up, the worker continues to press down the pedal with the heel so that the first abutment plate and the second abutment plate abut against the pole again.

[0023] Repeat the above operation with the other foot to move the other ring seat upward on the rod;

[0024] S6: Repeat step S5 until the worker climbs to the designated working position on the pole.

[0025] Compared with the prior art, the present invention provides an electric climbing device with a fall protection structure and its method of use, which has the following beneficial effects:

[0026] 1. The power climbing device with an anti-fall structure and its usage method, by setting a ring seat to surround the pole, can prevent the device from separating from the pole during climbing, and by using an abutment mechanism to tightly abut against the pole during climbing, effectively preventing falls during climbing, thereby improving the safety of power construction.

[0027] 2. The electric climbing device with an anti-fall structure and its usage method, through the positioning component, positions the first arc plate and the second arc plate, effectively preventing the ring seat from separating from the pole during climbing. When the guide plate at the end of the ring seat abuts against the pole, the positioning component automatically releases the positioning between the first arc plate and the second arc plate. The operation is simple and facilitates the improvement of construction progress.

[0028] 3. The electric climbing device with an anti-fall structure and its usage method: By lowering the heel height below the toes, the pedal drives the first abutment plate to flip via the swing rod. When the swing rod flips, it drives the second pull rope to move. The second pull rope pulls down the upper end of the elastic telescopic plate, causing the elastic telescopic plate to deflect around the fourth pivot. The elastic telescopic plate drives the second abutment plate to abut against the two sides of the pole, increasing the contact area between the ring seat and the pole. Before the first abutment plate abuts against the outer wall of the pole, the second abutment plate has already abutted against the pole. The elastic telescopic plate begins to contract and drives the sliding block to move upward in the sliding groove to ensure that the swing rod can pull the second pull rope normally. After the first abutment plate abuts against the side wall of the pole, the positioning of the ring seat and the pole is completed. During climbing, only one foot can be lifted to move upward, while the other foot supports, allowing the worker to ascend stably while climbing the pole.

[0029] 4. The electric climbing device with anti-fall structure and its usage method, by setting a grounding plate on the underside of the second contact plate, even if the ring seat slides down the pole, when the grounding plate contacts the ground, the third elastic element and the elastic telescopic plate play a role in unloading and buffering, reducing the risk of workers falling.

[0030] 5. The electric climbing device with anti-fall structure and its usage method, by setting an installation sleeve on the outside of the first abutment plate and the second abutment plate, the sharp protrusion on the outside of the installation sleeve can increase the friction with the pole, and avoid the device slipping due to the reduced friction between the first abutment plate and the pole caused by the pole being weathered, covered with moss or advertising paper, thereby improving the climbing stability.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 An electric climbing device with a fall protection structure includes a mounting base 1, and further includes:

[0047] The annular seat 2 includes a first arc plate 201 and a second arc plate 202 for surrounding the wire rod 3. The first arc plate 201 and the second arc plate 202 are rotatably connected to the two ends of the mounting base 1, and a positioning component is provided at the end of the first arc plate 201 and the second arc plate 202 away from the mounting base 1.

[0048] The abutting mechanism is mounted on the mounting base 1 and moves against the pole 3.

[0049] Specifically, when the device is in use, the first arc plate 201 and the second arc plate 202 surround and enclose the pole 3. The positioning component positions the enclosed state between the first arc plate 201 and the second arc plate 202, which can prevent the device from separating from the pole 3 when climbing. When the worker climbs the pole 3, the abutment mechanism makes a tight contact with the pole 3, which effectively prevents him from falling while climbing the pole 3, thereby improving the safety of power construction.

[0050] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A power climbing device with an anti-fall structure, based on embodiment 1, further includes a mounting base 1 comprising a main base 101 and side bases 102 fixed on both sides of the main base 101. A connecting seat 4 is provided on both the first arc plate 201 and the second arc plate 202. A first rotating shaft 401 is provided between the connecting seat 4 and the side base 102. A first torsion spring 402 is sleeved on the first rotating shaft 401, with its two ends respectively connected to the connecting seat 4 and the side base 102. A guide plate 5 is fixed at the end of the first arc plate 201 and the second arc plate 202 away from their respective connecting seats 4.

[0051] Specifically, the first arc plate 201 and the second arc plate 202 can rotate relative to the main body 101, so that the ends of the first arc plate 201 and the second arc plate 202 away from the main body 101 can separate from each other. In specific operation, the rod 3 is placed between the two guide plates 5, and then the ring seat 2 continues to move closer to the rod 3 and abut against it. After the two guide plates 5 are subjected to the abutting force with the rod 3, they separate from each other, so that the rod 3 passes between the two guide plates 5. As the ring seat 2 continues to move towards the rod 3, the rod 3 completely enters the enclosed area formed by the first arc plate 201 and the second arc plate 202. Then, the first arc plate 201 and the second arc plate 202 are reset and abut against each other under the action of the first torsion spring 402. The two guide plates 5 remain in abutting state under the action of the positioning component to prevent the ring seat 2 from separating from the rod 3 during climbing.

[0052] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 , Figure 10 and Figure 11A power climbing device with an anti-fall structure, based on embodiment 2, further includes a positioning component comprising a movable groove 6 on a first arc plate 201, a positioning rod 601 slidably connected in the movable groove 6, a first elastic element 602 disposed between the positioning rod 601 and the inner wall of the movable groove 6, a groove 7 on the positioning rod 601, a positioning block 701 slidably connected in the groove 7, and a second elastic element 702 disposed between the inner wall of the groove 7 and the positioning block 701. The second arc plate 202 is provided with a slot 8 that mates with the positioning rod 601, and the inner wall of the slot 8 is provided with a positioning hole 801 that mates with the positioning block 701.

[0053] Furthermore, a first pull rope 9 is fixed on the positioning block 701. The end of the first pull rope 9 away from the positioning block 701 passes through the positioning rod 601, the groove 7, and the movable groove 6 in sequence and is fixedly connected to the first arc plate 201. The first arc plate 201 and the guide plate 5 connected thereto are provided with a sliding groove 10 for the movement of the first pull rope 9. A second rotating shaft 11 is also fixed on the guide plate 5. A force plate 111 is provided on the second rotating shaft 11. A second torsion spring 112 is sleeved on the second rotating shaft 11. A pressure block 113 that moves against the first pull rope 9 is fixed on the force plate 111 of the first arc plate 201.

[0054] Specifically, the rod 3 is placed between the two guide plates 5, and then the annular seat 2 continues to move closer to and abut against the rod 3. The force plate 111 on the guide plate 5 first abuts against the outer wall of the rod 3, weakening the impact force of the annular seat 2 on the rod 3. The force plate 111 adheres to the guide plate 5 with the second rotating shaft 11 as the center, and the pressure block 113 on the force plate 111 presses against the first pull rope 9. The first pull rope 9, under force, causes the positioning block 701 to retract into the groove 7. Then, the first pull rope 9 transmits force to the positioning rod 601, causing the positioning rod 601 to retract into the movable groove 6. Both the first elastic element 602 and the second elastic element 702 are compressed. The elastic element 702 is set as a spring, and the first arc plate 201 and the second arc plate 202 are no longer restricted. As the first arc plate 201 and the second arc plate 202 continue to move toward the pole 3, the ends of the first arc plate 201 and the second arc plate 202 away from the mounting base 1 separate from each other and provide entry space for the pole 3. The ring seat 2 continues to move toward the pole 3 until the pole 3 is completely enclosed within the enclosed area formed by the first arc plate 201 and the second arc plate 202. At this time, the force plate 111 is no longer under force, and the positioning rod 601 drives the positioning block 701 to reset, so that the first arc plate 201 and the second arc plate 202 are inserted. The operation is simple and does not require additional manual operation by the staff, which facilitates the improvement of construction progress.

[0055] Example 4: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 and Figure 7 A power climbing device with an anti-fall structure, based on embodiment 3, further includes an abutment mechanism comprising a swing groove 12 formed on a mounting base 1, a third rotating shaft 121 rotatably connected within the swing groove 12, a swing rod 122 fixed on the third rotating shaft 121, and a third torsion spring 123 sleeved on the third rotating shaft 121, with its two ends respectively connected to the mounting base 1 and the swing rod 122, and the two ends of the swing rod 122 respectively connected to a pedal 124 and a first abutment plate 125.

[0056] Furthermore, the pedal 124 and the swing arm 122 are inclined, the heel position 1241 of the pedal 124 is lower than the toe position 1242, and the pedal 124 is provided with a strap 1243 for binding the foot.

[0057] Specifically, when climbing pole 3, the worker first secures their feet to the footrest 124 using straps 1243. Then, the footrest moves towards pole 3 via the mounting base 1, which in turn moves the ring seat 2. After the first arc plate 201 and the second arc plate 202 encircle pole 3, the heels of both feet are lower than the toes. The footrest 124, via the swing rod 122, rotates the first abutment plate 125. Once the first abutment plate 125 is pressed against the side wall of pole 3, the positioning of the ring seat 2 and pole 3 is complete. The worker then begins climbing. First, lift one foot so that the heel is higher than the toes. The swing lever 122 drives the first abutment plate 125 to rotate back to its original position. The first abutment plate 125 no longer abuts against the pole 3. At this time, the moving resistance between the ring seat 2 and the pole 3 is reduced. After the lifted foot moves the ring seat 2 upward, continue to press down the pedal 124 with the heel so that the first abutment plate 125 and the second abutment plate 132 abut against the pole 3 again. Repeat the above operation with the other foot to move the other ring seat 2 upward on the pole 3 until the worker climbs to the designated working position on the pole 3.

[0058] Example 5: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A power climbing device with an anti-fall structure, based on embodiment 4, further includes a support plate 14 fixed on the first arc plate 201 and the second arc plate 202. A second pull rope 141 is slidably connected in each support plate 14. A fourth rotating shaft 13 is rotatably arranged on both the first arc plate 201 and the second arc plate 202. An elastic telescopic plate 131 is fixed on the fourth rotating shaft 13. The fixed end of the elastic telescopic plate 131 is fixedly connected to the fourth rotating shaft 13. The telescopic end of the elastic telescopic plate 131 is connected to a second abutment plate 132. One end of the elastic telescopic plate 131 away from the second abutment plate 132 is fixedly connected to one end of the second pull rope 141. The end of the second pull rope 141 away from the elastic telescopic plate 131 passes through the support plate 14 and the mounting base 1 and is connected to the lower side of the swing rod 122. The second pull rope 141 and the first pull rope 9 are made of steel wire rope.

[0059] Furthermore, a sliding groove 1321 is provided on the second abutment plate 132, and a sliding block 1322 is slidably connected in the sliding groove 1321. A third elastic element 1323 is provided between the sliding block 1322 and the inner wall of the sliding groove 1321. The sliding block 1322 is movably connected to the end of the elastic telescopic plate 131 away from the second pull rope 141 through a pin. A grounding plate 15 is provided at the bottom of the second abutment plate 132 through a connecting block.

[0060] Specifically, the heels of both feet are lower than the toes. The pedal 124 drives the first abutment plate 125 to rotate via the swing rod 122. When the swing rod 122 rotates, it drives the second pull rope 141 to move. The second pull rope 141 pulls down on the upper end of the elastic telescopic plate 131, causing the elastic telescopic plate 131 to deflect around the fourth pivot 13. The elastic telescopic plate 131 drives the second abutment plate 132 to abut against the two sides of the rod 3, increasing the contact area between the annular seat 2 and the rod 3. Before the first abutment plate 125 abuts against the outer wall of the rod 3, the second abutment plate 132 has already abutted against the rod 3. When the pole 3 abuts, the elastic telescopic plate 131 begins to retract and drives the sliding block 1322 to move upward within the sliding groove 1321, ensuring that the swing rod 122 can pull the second pull rope 141 normally. After the first abutting plate 125 abuts against the side wall of the pole 3, the positioning work between the annular seat 2 and the pole 3 is completed. By setting a grounding plate 15 on the lower side of the second abutting plate 132, even if the annular seat 2 slides down the pole 3, when the grounding plate 15 contacts the ground, the third elastic element 1323 and the elastic telescopic plate 131 play a role in unloading force and buffering, reducing the risk of workers falling.

[0061] Example 6: Refer to Figure 12A power climbing device with an anti-fall structure, based on embodiment 5, further includes a mounting sleeve 16 on both the second abutment plate 132 and the first abutment plate 125. One end of the mounting sleeve 16 is provided with an anti-slip surface, and several sharp protrusions 161 are provided on the anti-slip surface. A mounting hole 162 is opened on the side of the mounting sleeve 16 away from the anti-slip surface, and a bolt is movably connected in the mounting hole 162.

[0062] Specifically, the mounting sleeve 16 is installed on the outside of the first abutment plate 125 and the second abutment plate 132 by bolts. The sharp protrusion 161 on the outside of the mounting sleeve 16 can increase the friction with the pole 3, and prevent the first abutment plate 125 and the second abutment plate 132 from slipping due to weathering, moss or advertising paper on the pole 3. This improves the climbing stability.

[0063] This invention also discloses a method of using an electric climbing device with a fall protection structure, comprising the following steps:

[0064] S1: When the staff climbs pole 3, they first tie their feet to the footboard 124 with straps 1243, and then their feet move towards pole 3 by driving the ring seat 2 through the mounting seat 1.

[0065] S2: Place the rod 3 between the two guide plates 5, and then move the annular seat 2 closer to the rod 3 and abut it. The force plate 111 on the guide plate 5 first abuts against the outer wall of the rod 3. The force plate 111 weakens the impact force of the annular seat 2 on the rod 3. The force plate 111 adheres to the guide plate 5 with the second rotating shaft 11 as the center. The pressure block 113 on the force plate 111 presses the first pull rope 9. The first pull rope 9 is forced to move the positioning block 701 to retract into the groove 7. Then the first pull rope 9 transmits the force to the positioning rod 601, causing the positioning rod 601 to retract into the movable groove 6. The first elastic element 602 and the second elastic element 702 are both compressed, and the first arc plate 201 and the second arc plate 202 are no longer restricted.

[0066] S3: As the first arc plate 201 and the second arc plate 202 continue to move toward the rod 3, the ends of the first arc plate 201 and the second arc plate 202 away from the mounting base 1 separate from each other and provide entry space for the rod 3. The ring seat 2 continues to move toward the rod 3 until the rod 3 is completely inside the enclosed area formed by the first arc plate 201 and the second arc plate 202. At this time, the force plate 111 is no longer under force, and the positioning rod 601 drives the positioning block 701 to reset, so that the first arc plate 201 and the second arc plate 202 are inserted.

[0067] S4: After the ring seats 2 on both feet surround the line rod 3, the height of the heels of both feet is lower than the toes. The pedal 124 drives the first abutment plate 125 to flip through the swing rod 122. When the swing rod 122 flips, it drives the second pull rope 141 to move. The second pull rope 141 pulls down the upper end of the elastic telescopic plate 131, causing the elastic telescopic plate 131 to deflect around the fourth pivot 13. The elastic telescopic plate 131 drives the second abutment plate 132 to abut against the two sides of the line rod 3, increasing the contact area between the ring seat 2 and the line rod 3. Before the first abutment plate 125 abuts against the outer wall of the line rod 3, the second abutment plate 132 has already abutted against the line rod 3. The elastic telescopic plate 131 begins to contract and drives the sliding block 1322 to move upward in the sliding groove 1321 to ensure that the swing rod 122 pulls the second pull rope 141 normally. After the first abutment plate 125 abuts against the side wall of the line rod 3, the positioning work of the ring seat 2 and the line rod 3 is completed.

[0068] S5: When starting the climbing work, the worker first raises one foot so that the heel is higher than the toes. The swing rod 122 drives the first abutment plate 125 to return to its original position and rotate. The first abutment plate 125 no longer abuts against the pole 3. At the same time, the second pull rope 141 no longer pulls down the elastic telescopic plate 131. The second abutment plate 132 returns to its original position. At this time, the moving resistance between the ring seat 2 and the pole 3 is reduced. After the raised foot drives the ring seat 2 to move up, the worker continues to press down the pedal 124 with the heel so that the first abutment plate 125 and the second abutment plate 132 abut against the pole 3 again.

[0069] Repeat the above operation with the other foot to move the other ring seat 2 upward on the rod 3;

[0070] S6: Repeat step S5 until the worker climbs to the designated working position on pole 3.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. A method of using the electric climbing device with a fall protection structure according to claim 6, characterized in that, Includes the following steps: S1: When the staff climbs the pole (3), they first tie their feet to the footboard (124) with straps (1243), and then their feet move towards the pole (3) via the mounting seat (1) and the ring seat (2). S2: Place the rod (3) between the two guide plates (5), and then make the ring seat (2) continue to move closer to the rod (3) and abut. The force plate (111) on the guide plate (5) first abuts against the outer wall of the rod (3). The force plate (111) weakens the impact force of the ring seat (2) on the rod (3). The force plate (111) adheres to the guide plate (5) with the second rotating shaft (11) as the center. The pressure block (113) on the force plate (111) presses the first pull rope (9). The first pull rope (9) is forced to move the positioning block (701) to retract in the groove (7). Then the first pull rope (9) transmits the force to the positioning rod (601), causing the positioning rod (601) to retract into the movable groove (6). The first elastic element (602) and the second elastic element (702) are both compressed. The first arc plate (201) and the second arc plate (202) are no longer restricted. S3: As the first arc plate (201) and the second arc plate (202) continue to move toward the rod (3), the ends of the first arc plate (201) and the second arc plate (202) away from the mounting base (1) separate from each other and provide space for the rod (3) to enter. The ring seat (2) continues to move toward the rod (3) until the rod (3) is completely inside the enclosed area formed by the first arc plate (201) and the second arc plate (202). At this time, the force plate (111) is no longer under force, and the positioning rod (601) drives the positioning block (701) to reset, so that the first arc plate (201) and the second arc plate (202) are inserted. S4: After the ring seats (2) on both feet surround the line pole (3), the height of the heels of both feet is lower than the toes. The pedal (124) drives the first abutment plate (125) to flip through the swing rod (122). When the swing rod (122) flips, it drives the second pull rope (141) to move. The second pull rope (141) pulls down on the upper end of the elastic telescopic plate (131), causing the elastic telescopic plate (131) to deflect around the fourth pivot (13). The elastic telescopic plate (131) drives the second abutment plate (132) and the line pole (3) to move together. The two sides of the ring seat (2) abut against each other, increasing the contact area between the ring seat (2) and the rod (3). Before the first abutting plate (125) abuts against the outer wall of the rod (3), the second abutting plate (132) has already abutted against the rod (3). The elastic telescopic plate (131) begins to contract and drives the sliding block (1322) to move upward in the sliding groove (1321) to ensure that the swing rod (122) pulls the second pull rope (141) normally. After the first abutting plate (125) abuts against the side wall of the rod (3), the positioning work of the ring seat (2) and the rod (3) is completed. S5: When starting the climbing work, the worker first raises one foot so that the heel is higher than the toes. The swing rod (122) drives the first abutment plate (125) to reset and rotate. The first abutment plate (125) no longer abuts against the pole (3). At the same time, the second pull rope (141) no longer pulls down the elastic telescopic plate (131). The second abutment plate (132) resets. At this time, the moving resistance between the ring seat (2) and the pole (3) is reduced. After the raised foot drives the ring seat (2) to move up, the worker continues to press down the pedal (124) with the heel so that the first abutment plate (125) and the second abutment plate (132) abut against the pole (3) again. Repeat the above operation with the other foot to move the other ring seat (2) up on the rod (3); S6: Repeat step S5 until the worker climbs to the designated work position on the pole (3).
