[0047] A spring 13 is hinged between one end of the second swing link 102 away from the synchronous tooth and one end of the fourth swing link 104 away from the synchronous tooth; the spring 13 shortens the distance between the first limit connecting plate 401 and the second limit connecting plate 402 through the second swing link 102 and the fourth swing link 104, and provides initial preload force for the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602.

[0048] The first limiting connection plate 401, the second limiting connection plate 402, and the side of the wearing connection plate are all provided with through holes, and the wearer's safety belt can pass through the through holes.

[0049] The mounting plate 2 is an axisymmetric plate-like structure; a through hole is provided on the side of the mounting plate 2, and the wearer's safety belt can pass through the through hole.

[0050] like Figure 8As shown: the first motor 501, the second motor 502, the third motor 503 and the fourth motor 504 are winch motors with the same rotation speed, two in a group, with opposite rotation directions, responsible for providing strong power to drive the special-shaped synchronous belt 6 to rotate;

[0051] A pig tail guide frame 8 is provided on the mounting plate 2 along the axial direction of the traction rope 11 to guide the direction of the traction rope 11 and facilitate the installation of the traction rope 11.

[0052] like Fig.11 As shown: the inner rings of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 are provided with inner ring synchronous teeth for transmitting the torque of the first motor 501, the second motor 502, the third motor 503 and the fourth motor 504 through the synchronous belt pulleys respectively matched therewith.

[0053] The outer ring teeth of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 have concave arc-shaped grooves. During the extrusion and biting process of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602, the hole formed by the extrusion of the arc-shaped groove can just hold a rope. The diameter of the arc-shaped groove is smaller than the diameter of the rope, and the clamping range can be adjusted according to the diameter of the rope.

[0054] The materials of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 are composite materials with high wear resistance and high toughness.

[0055] A battery pack 9 for providing power and connected to the first motor 501, the second motor 502, the third motor 503 and the fourth motor 504 is arranged on the first synchronous belt support frame 701, and an electronic control package 10 for adjusting the rotation speed and direction of the motor and connected to the battery pack 9, the first motor 501, the second motor 502, the third motor 503 and the fourth motor 504 respectively is arranged on the second synchronous belt support frame 702; during the mutual opposite rotation of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602, the traction rope 11 and the belt teeth of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 produce relative motion, thereby pulling and driving the mounting plate 2 to move relative to the traction rope 11.

[0056] The battery pack 9 has the same shape as the electronic control pack 10 and is symmetrically arranged along the axis of the traction rope 11 .

[0057] The first motor 501, the second motor 502, the third motor 503 and the fourth motor 504 have the same rotation speed, are grouped in pairs, and have opposite directions, and are responsible for providing strong power to drive the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 to rotate; the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 have opposite directions and rotate toward the side of the traction rope 11, thereby generating an upward squeezing force on the traction rope 11, forming an overall climbing effect along the traction rope 11; the pig tail guide frame 8 is used to guide the direction of the traction rope 11 to facilitate the installation of the traction rope 11; the first limiting connecting plate 401 and the second limiting connecting plate 402 provide the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 with an initial estimated force through the spring 13, so that the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 can bite the traction rope 11 without bearing the load of the wearer. During the rising process of the device, the uneven pulling force applied by the wearer to the left and right sides is converted into power for driving the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 to be synchronously clamped centripetally through the mutual meshing of the synchronous teeth of the first swing connecting plate 101 and the second swing connecting plate 102 connected to the first limit connecting plate 401 and the second limit connecting plate 402; and the mutual meshing of the synchronous teeth of the third swing connecting plate 103 and the fourth swing connecting plate 104.

[0058] The outer ring teeth of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 have concave arc grooves. During the extrusion and biting process of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602, the hole formed by the extrusion of the arc groove can just hold the traction rope 11 tightly. The diameter of the hole formed by the extrusion of the arc groove is slightly smaller than the diameter of the rope, and the clamping range can be adjusted according to the diameter of the traction rope 11. The first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 have opposite directions, which produce extrusion force on the rope, and will not slip under the action of friction; when the first motor 501 and the second motor 502 drive the first special-shaped synchronous belt 601, and the third motor 503 and the fourth motor 504 drive the second special-shaped synchronous belt 602 to rotate continuously, the entire device has continuous upward traction, providing the wearer with continuous upward power.

[0059] There are two fixed points on the first limit connecting plate 401 and the second limit connecting plate 402, wherein the first fixed point of the first limit connecting plate 401 is hinged to the mounting plate 2, and the second fixed point of the first limit connecting plate 401 is connected to the wearing connecting plate, the first motor 501 and the second motor 502 bearings; the first fixed point of the second limit connecting plate 402 is hinged to the mounting plate 2, and the second fixed point of the second limit connecting plate 402 is connected to the wearing connecting plate, the third motor 503 and the fourth motor 504 bearings;

[0060] The wearing connecting plate is connected to the wearer's safety belt, that is, the wearer passes the safety belt through the through hole of the wearing connecting plate, and the connection between the mounting plate 2 and the first limiting connecting plate 401 and the second limiting connecting plate 402 acts as a fixed fulcrum. When a certain preload force is applied to the spring 13 installed between the second swing connecting plate 102 and the fourth swing connecting plate 104, the spring 13 shortens the distance between the first limiting connecting plate 401 and the second limiting connecting plate 402 through the first swing connecting plate 101 and the fourth swing connecting plate 104, thereby providing an initial preload force for the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602. In the process of the entire device pulling the wearer upward, due to the relationship between the action force and the reaction force, the wearer will also generate a reaction pulling force on the device through the wearing connecting plate, and because the wearer's left and right feet take turns to exert force when climbing the tower, the pulling force generated on the wearing connecting plate is also uneven, through the mutual meshing of the synchronous teeth of the first swing connecting plate 101 and the second swing connecting plate 102; the mutual meshing of the synchronous teeth of the third swing connecting plate 103 and the fourth swing connecting plate 104, the power is converted into power to drive the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 to clamp each other.

[0061] like Figure 1 As shown: the hinge point between the mounting plate 2 and the third swing connecting plate 103 provides a fixed fulcrum ZD;

[0062] The first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 generate pressure on the traction rope 11. When the gravity and the friction force are balanced, the output force of the driving motor provides the power for upward acceleration. The entire force-bearing simplified structure is as follows: Figure 7 As shown:

[0063] The mounting plate 2 is fixedly worn on the person, and the force exerted by the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 on the traction rope 11 is simplified into one force point. The secondary simplified force is as follows: Figure 8 As shown;

[0064] At this time, the simplified force analysis diagram is as follows Fig. 9 As shown:

[0065] Where: G' is the device's own gravity, F N F is the reverse pressure generated by the traction rope 11 on the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602, A is the pulling force of the movable two-way rod on the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602;

[0066] G' / F N =tanα, where α = (0°~30°), that is, 0 <tanα<0.57,

[0067] It is known that after the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 press the traction rope 11, the device is subjected to the upward friction force μF of the traction rope 11 N , and the downward gravity G', in order for the equipment to be firmly stuck on the traction rope 11 when the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 are not rotating, the friction force and the gravity need to be equal, such as Fig.10 As shown:

[0068] μF N =G', μ = G' / F N ,

[0069] That is, 0<μ<0.57, that is, as long as the friction coefficient of the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 to the traction rope 11 is greater than or equal to 0.57, no matter how G' changes, the device can be firmly stuck on the traction rope 11.

[0070] Steps:

[0071] Step 1: Fig.11 As shown: Wear the safety belt, connect the tower climbing device to the safety belt, and wear it on your chest or waist.

[0072] Step 2: If Fig.12 As shown: manually open the first limit connecting plate 401 and the second limit connecting plate 402, and wind the traction rope 13 into the pig tail guide frame 8 for assisting tower climbing.

[0073] Step 3: Start the power supply of the battery pack 9. Driven by the motor, the first special-shaped synchronous belt 601 and the second special-shaped synchronous belt 602 rotate clockwise and counterclockwise, so that the assisting device climbs up along the traction rope 11. During the climbing process, the squeezing force automatically adapts to the pulling force of the human body on the equipment, thereby always ensuring sufficient meshing force.

[0074] The present invention provides a transmission line tower climbing assist device, which is small and light, powerful, quick and easy to install, and highly safe. It can be used in rope traction operations, stably provide strong traction force, and move stably along the rope with a traction rope or a traction device. It can be flexibly used in tower climbing by power workers and in various rope traction operation scenarios.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
