Description

Technical Field

[0001] The present invention belongs to the technical field of climbing tools, and in particular relates to an auxiliary device for climbing an electric tower. Background Art

[0002] In the power transmission system, power lines are supported by power towers. When power maintenance is required, workers need to use auxiliary equipment to climb to the top of the tower. The tower consists of a tower body and multiple footrests.

[0003] In the existing technology, our unit has designed a climber, referring to Figure 1 The climber 4 includes a climber body 41, a clamping block 42 and a clamping rod 44. A groove is provided on the upper part of the climber body 41, and the clamping rod 44 is rotatably connected to the groove of the climber body 41. A U-shaped clamping hole 411 is provided at the front end of the climber body 41, and a clamping block 42 with a hook-shaped structure is provided at the front end of the clamping rod 44. When the user holds the climber body 41 and brings the clamping hole 411 close to the pedal 5, presses the rear end of the clamping rod 44, and the clamping block 42 at the front end of the clamping rod 44 opens. After the pedal 5 is clamped into the clamping hole, the clamping rod 44 is released. The clamping block 42 at the front end of the clamping rod 44 closes the opening at the front end of the clamping hole 411 under the action of the first spring 43, thereby fixing the pedal 5.

[0004] During long-term use and verification, it was found that when using this climber, the clamping rod needs to be pressed twice (when engaging and releasing the foot pedal) for each step of climbing. Since the height of the pole tower is generally high, pressing the clamping rod multiple times during the climbing process will cause soreness in the thumb joint. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an electric tower climbing assist device to solve the problem of physical discomfort to operators caused by the need to press the compression rod multiple times when using the existing pole tower assist climber.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] 18. The repairing kit for automotive dents, according to claim 1, wherein the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a orifice, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut.

[0008] By adopting the above technical solution, when the operator climbs along the power tower, he holds the gripping plate and moves the gripping plate so that the footrest is located on one side of the clamping groove, and then moves the gripping plate forward so that the footrest is clamped into the clamping groove. At this time, the first clamping block and the second clamping block rotate around the pin shaft to close the opening of the clamping groove. Since the operator's hand is above the head, the operator's legs and feet will continue to apply downward pulling force to the gripping plate as the body moves upward, so the footrest will be firmly fixed in the clamping groove; after the operator climbs up, the operator's hand moves upward, and the auxiliary device can be unlocked by simply pulling the gripping plate backward. Compared with the related art, this method uses the upward movement posture of the person during the climbing process and uses the first clamping block and the second clamping block to lock the footrest. It does not require the operator to press the clamping rod as in the existing climber, which increases the extra workload of the person, thereby making it easier for the person to use the auxiliary device for climbing operations.

[0009] As a further optimization of the present technical solution, a double torsion spring is provided on the pin shaft, both ends of the double torsion spring are inserted in the avoidance groove, the middle part of the double torsion spring is arranged on the upper part of the second clamping block, and in the initial state, the first clamping block is located in the third accommodating groove, and the second clamping block is located in the first accommodating groove, so that the clamping assembly is open outward in the initial state. When the pedal is clamped in the clamping groove, the double torsion spring is deformed, and the first clamping block rotates from the third accommodating groove to the first accommodating groove, and the second clamping block rotates from the first accommodating groove to the second accommodating groove. At this time, the double torsion spring has elastic force on the second clamping block, which facilitates the rapid reset of the clamping assembly.

[0010] As a further preferred embodiment of the present technical solution, the inner walls of the first clamping block and the second clamping block are provided with a plurality of evenly arranged serrations, which increase the friction between the device and the pedal, enable the pedal to be clamped more firmly, and increase the safety of the operator.

[0011] As a further preferred embodiment of the present technical solution, a limit block is provided on the upper portion of the avoidance groove, and the limit block is arranged between the second accommodating groove and the third accommodating groove to limit the rotation angle of the first clamping block.

[0012] As a further preferred embodiment of the present technical solution, a fixing assembly is provided on one side of the buckling plate, and a positioning hole is provided on one side of the first clamping block, and the fixing assembly includes a sleeve, which is fixedly mounted on one side of the buckling plate, and a positioning pin is provided in the sleeve, which passes through the side wall of one side of the buckling plate and is slidably connected to the buckling plate, and a second spring is provided on one side of the positioning pin, and the other end of the second spring is against the inner wall of the sleeve. In the initial state, the second spring is in a compressed state, and when the second spring is in a natural state, the positioning pin passes through the buckling plate and is inserted into the positioning hole; thus, when the buckling assembly and the buckling plate lock the pedal, the positioning pin is inserted into the positioning hole, which prevents the buckling assembly from automatically loosening and further ensures the safety of the operator; when the pedal needs to be unlocked, the operator pulls the holding plate horizontally backward, and the pedal hits the first clamping block. Under the action of the impact, the positioning pin falls off from the positioning hole, and the rotation of the buckling assembly can be restored.

[0013] As a further optimization of the present technical solution, a plurality of finger grooves are provided on the lower portion of the gripping plate to facilitate the operator to grip the gripping plate and increase the comfort of the human hand gripping the gripping plate.

[0014] As a further preferred embodiment of the present technical solution, a plurality of weight-reducing holes are provided at the lower portion of the gripping plate to reduce the weight of the auxiliary device.

[0015] As a further optimization of this technical solution, a safety belt hanging hole is also provided on the gripping plate. The operator wears a safety belt and hangs the safety belt hook in the safety belt hanging hole, which avoids the need to move the hook every time the operator climbs a step, thereby improving the efficiency of the operator's climbing.

[0016] As a further preferred embodiment of the present technical solution, the inner diameter of the opening of the clamping groove gradually increases toward the outer side of the opening of the clamping groove, so as to facilitate the operator to quickly clamp and fix the auxiliary device to the pedal.

[0017] The beneficial effects of the present invention are:

[0018] 1) The present invention utilizes a snap-fit ​​assembly and a buckle plate to lock the footrest, and utilizes the operator's movements and posture during the climbing process to unlock the device, eliminating the need for the operator to repeatedly press the clamping rod, thereby improving the operator's climbing efficiency and comfort.

[0019] 2) A double torsion spring is provided on the pin shaft. In the initial state, the first clamping block is located in the third accommodating groove, and the second clamping block is located in the first accommodating groove, so that the clamping assembly is opened outward in the initial state. When the pedal is clamped into the clamping groove, the double torsion spring is deformed, and the first clamping block rotates from the third accommodating groove to the first accommodating groove, and the second clamping block rotates from the first accommodating groove to the second accommodating groove. At this time, the double torsion spring has elastic force on the second clamping block, which facilitates the rapid reset of the clamping assembly.

[0020] 3) The inner walls of the first clamping block and the second clamping block are both provided with a number of evenly arranged serrations, which increase the friction between the device and the pedal, making the pedal connection more secure and increasing the safety of the operator.

[0021] 4) A limit block is provided on the upper portion of the avoidance groove, and the limit block is arranged between the second accommodating groove and the third accommodating groove to limit the rotation angle of the first clamping block.

[0022] 5) A fixing assembly is provided on one side of the snap-fit ​​plate, and a positioning hole is provided on one side of the first clamping block. In the initial state, the second spring is in a compressed state, and when the second spring is in a natural state, the positioning pin passes through the snap-fit ​​plate and is inserted into the positioning hole; therefore, when the snap-fit ​​assembly and the snap-fit ​​plate lock the pedal, the positioning pin is inserted into the positioning hole, which prevents the snap-fit ​​assembly from automatically loosening and further ensures the safety of the operator; when the pedal needs to be unlocked, the operator pulls the grip plate horizontally backward, and the pedal hits the first clamping block. Under the action of the impact, the positioning pin falls off from the positioning hole, and the rotation of the snap-fit ​​assembly can be restored.

[0023] 6) Several finger grooves are provided at the bottom of the gripping plate to facilitate the operator to hold the gripping plate and increase the comfort of the human hand holding the gripping plate.

[0024] 7) Several weight-reducing holes are provided at the bottom of the gripping plate to reduce the weight of the auxiliary device.

[0025] 8) The gripping plate is also provided with a safety belt hanging hole. The operator wears a safety belt and hangs the safety belt hook in the safety belt hanging hole, which avoids the need to move the hook every time the operator climbs a step, thereby improving the efficiency of the operator's climbing.

[0026] 9) The inner diameter of the opening of the clamping groove gradually increases toward the outer side of the opening of the clamping groove, which makes it easier for the operator to quickly clamp and fix the auxiliary device to the pedal. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 2-5As shown, an electric tower climbing assist device includes a gripping plate 1 and a clamping assembly 3; a gripping hole 11 is provided in the middle of the gripping plate 1 for the operator to hold the gripping plate 1 tightly, a buckle plate 2 is integrally formed on the upper end of the gripping plate 1, a clamping groove 22 is provided at the connection between the buckle plate 2 and the gripping plate 1, and one side of the clamping groove 22 is opened; an avoidance groove 21 is provided on the buckle plate 2, and the avoidance groove 21 includes a first accommodating groove 211, a second accommodating groove 212 and a third accommodating groove 213, wherein the first accommodating groove 211 is located on the side of the clamping groove 22 close to the gripping plate 1, and the second accommodating groove 2 12 is located on the side of the clamping slot 22 away from the opening of the clamping slot 22 itself, the third accommodating slot 213 is located on the side of the clamping slot 22 away from the holding plate 1, and the first accommodating slot 211, the second accommodating slot 212, the third accommodating slot 213 and the clamping slot 22 are interconnected; the middle part of the clamping assembly 3 is rotatably installed in the second accommodating slot 212 through a pin shaft 31, and the clamping assembly 3 includes a first clamping block 33 and a second clamping block 34 integrally formed with one end of the first clamping block 33, and the inner walls of the first clamping block 33 and the second clamping block 34 constitute a hook-shaped structure for inserting the pedal 5.

[0037] By adopting the above technical solution, when the operator climbs along the power tower, he holds the holding plate 1 and moves the holding plate 1 so that the pedal 5 is located on one side of the clamping groove 22, and then moves the holding plate 1 forward to make the pedal 5 clamped into the clamping groove 22. At this time, the first clamping block 33 and the second clamping block 34 rotate around the pin shaft 31 to close the opening of the clamping groove 22. Since the operator's hands are above the head, the operator's legs and feet will continue to apply downward pulling force to the holding plate 1 as the body moves upward, so the pedal 5 will be firmly fixed in the clamping groove 22; after the operator climbs up, the operator's hands move upward, and the auxiliary device can be unlocked by simply pulling the holding plate 1 backward. Compared with the related art, this method utilizes the upward movement required by the person during the climbing process and uses the first clamping block 33 and the second clamping block 34 to lock the footrest 5. It does not require the operator to press the clamping rod 44 as in the existing climber 4, which increases the operator's extra workload, thereby facilitating the use of the auxiliary device for climbing operations.

[0038] like Figure 5As shown, in this embodiment, a double torsion spring 32 is provided on the pin shaft 31, and both ends of the double torsion spring 32 are inserted in the avoidance groove 21, and the middle part of the double torsion spring 32 is arranged on the upper part of the second clamping block 34, and in the initial state, the first clamping block 33 is located in the third accommodating groove 213, and the second clamping block 34 is located in the first accommodating groove 211, so that the clamping component 3 is open outward in the initial state. When the pedal 5 is clamped in the clamping groove 22, the double torsion spring 32 is deformed, and the first clamping block 33 rotates from the third accommodating groove 213 to the first accommodating groove 211, and the second clamping block 34 rotates from the first accommodating groove 211 to the second accommodating groove 212. At this time, the double torsion spring 32 has an elastic force on the second clamping block 34, which facilitates the rapid reset of the clamping component 3.

[0039] like Figure 5 As shown, in this embodiment, the inner walls of the first clamping block 33 and the second clamping block 34 are provided with a plurality of evenly arranged serrations 35, which increase the friction between the device and the pedal 5, enable the pedal 5 to be clamped more firmly, and increase the safety of the operator.

In the initial state, the second spring 364 When the pedal is in a compressed state and the second spring 364 is in a natural state, the locating pin 363 passes through the snap plate 2 and is inserted into the locating hole 361; thus, when the snap assembly 3 and the snap plate 2 lock the pedal, the locating pin 363 is inserted into the locating hole 361, which prevents the snap assembly 3 from automatically loosening and further ensures the safety of the operator; when the pedal needs to be unlocked, the operator pulls the gripping plate 1 horizontally backward, and the pedal hits the first snap block 33. Under the action of the impact, the locating pin 363 falls off from the locating hole 361, and the rotation of the snap assembly 3 can be restored.

[0042] like Figure 2 As shown, in this embodiment, a plurality of finger grooves 12 are provided at the lower portion of the gripping plate 1 to facilitate the operator to grip the gripping plate 1 and increase the comfort of the human hand gripping the gripping plate 1 .

[0043] like Figure 2 As shown, in this embodiment, a plurality of weight-reducing holes 13 are provided at the lower portion of the gripping plate 1 to reduce the weight of the auxiliary device.

[0044] like Figure 2 As shown, in this embodiment, a safety belt hanging hole 14 is further provided on the gripping plate 1.
