[0002] In the power industry, pole towers are the supports used to support overhead transmission lines. Mostly constructed of steel or reinforced concrete, they serve as the primary support structure for overhead transmission lines. For line maintenance personnel, climbing poles to repair power lines is an essential step, and standardized operations are directly related to the safety of operators and the safe operation of the power system.

[0003] Climbing aids are essential tools for pole climbing. Currently, the most commonly used climbing aid is a rubber foot buckle.

Each upward step requires the climber to overcome their own gravity, exerting considerable energy. Furthermore, the foot buckle must be adjusted constantly throughout the climb. Adjusting one foot buckle shifts the body's center of gravity to the other side, requiring the other leg and foot to support the entire body weight. This poses a risk of falling from height due to exhaustion.

[0004] Therefore, how to improve operating efficiency while reducing the labor intensity of operators has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0032] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] Based on the defects in the prior art, Figure 1-3 The pole tower climbing device of the utility model is described in detail.

[0034] like Figure 1-3 As shown, it is a structural schematic diagram of a preferred embodiment of the pole tower climbing device of the present invention. The pole tower climbing device includes a climbing drive mechanism 1, a driving wheel assembly 2, a universal joint 4 and a foot buckle assembly 3. The driving wheel assembly 2 of this embodiment includes an active driving wheel 21 and an active driving shaft 22. The active driving shaft 22 is arranged on both sides of the climbing drive mechanism 1. The active driving wheel 21 is arranged on the active driving shaft 22. The end of the active driving shaft 22 is transmission-connected with the universal joint 4. The active driving wheel 21 is spaced apart from the universal joint 4 through the active driving shaft 22 to form a circular ring structure. The foot buckle assembly 3 is fixed to the periphery of the circular ring structure. The climbing drive mechanism 1 drives the active driving wheel 21 to move up and down along the axial direction of the pole tower 8 through the active driving shaft 22.

[0035] The active drive wheel 21, the active drive shaft 22, and the universal joint 4 of this embodiment all include a plurality of active drive wheels 21. The active drive shaft 22 is mounted on the active drive shaft 22. Adjacent active drive shafts 22 are connected by universal joints 4. That is, the active drive shaft 22 and the universal joint 4 are arranged at intervals. The plurality of universal joints 4 and the plurality of active drive shafts 22 form an annular structure, which can be sleeved on the pole tower 8. When the climbing drive mechanism 1 drives the active drive shaft 22 to rotate, the active drive shaft 22 drives the active drive wheel 21 to rotate. As the active drive wheel 21 rotates, climbing on the pole tower 8 is achieved, thereby replacing the active climbing of the operator and improving the working efficiency.

[0036] As a preferred embodiment, Figure 1As shown, the climbing drive mechanism 1 includes a climbing motor 11 and a climbing gearbox 12 , the climbing motor 11 is drivingly connected to the climbing gearbox 12 , and the active drive shaft 22 is provided on both sides of the climbing gearbox 12 and is drivingly connected to the climbing gearbox 12 at the same time.

[0037] The climbing motor 11 serves as a power mechanism and is driven and connected to the climbing gearbox 12. The climbing gearbox 12 is driven and connected to the active drive shaft 22. The climbing gearbox 12 can be used to adjust the output speed of the active drive shaft 22. Since the climbing motor 11 serves as a power mechanism, it can save manpower of the operating personnel.

[0038] The active drive wheels 21 of this embodiment are mounted on the active drive shaft 22. The active drive shaft 22 rotates under the drive of the climbing motor 11, so the active drive wheels 21 also rotate. Different active drive wheels 21 are connected by universal joints 4, which can realize power transmission. That is, the upper active drive wheel 21 transmits power to the next active drive wheel 21, thereby realizing that all the active drive wheels 21 rotate. When the active drive wheels 21 rotate, it is the climbing process on the tower 8.

[0039] At the same time, the climbing motor 11 of this embodiment can realize both forward rotation and reverse rotation to achieve the purpose of ascending or descending the climbing device.

[0040] As a preferred embodiment, continue to refer to Figure 1 As shown, it also includes a diameter-changing driving mechanism 5, which is arranged between adjacent active driving wheels 21 and is used to control the radius of the annular structure.

[0041] The variable diameter drive mechanism 5 here is used to control the radius of the circular ring structure composed of the drive shaft and the universal joint 4. The radius can be adjusted to adapt to pole towers 8 of different radii. For example, if the bottom end of the pole tower 8 is generally thicker, the circular ring structure will be enlarged, and when it reaches the top end of the pole tower 8, the circular ring structure will be reduced.

[0042] In detail, the variable diameter drive mechanism 5 is provided with an active drive shaft 22 extending to both sides. The active drive shaft 22 here is two of the above-mentioned active drive shafts 22. The interval between the active drive shafts 22 is adjusted by the variable diameter drive mechanism 5. The active drive shaft 22 is driven and connected to the active drive wheel 21.

[0043] The variable diameter drive mechanism 5 includes a variable diameter motor 51 and a variable diameter gearbox 52. The variable diameter motor 51 is driven and connected to the variable diameter gearbox 52. The variable diameter gearbox 52 is driven and connected to the active drive shafts 22 extending on both sides, and is used to control the distance between the active drive shafts 22 extending on both sides.

[0044] The driving connection between the variable diameter gearbox 52 and the active drive shaft 22 is preferably a meshing transmission connection.

[0045] The variable diameter gearbox 52 has several gears, which are arranged in pairs and have a certain spacing. The variable diameter motor 51 drives the gears to rotate. Since the active drive shaft 22 also has teeth, the symmetrical gears are simultaneously engaged with the active drive shafts 22 extending on both sides through the teeth. Through the rotation of the gears, the active drive shafts 22 on both sides are driven to move in the direction of approaching or moving away, thereby achieving the purpose of variable diameter.

[0046] As a preferred embodiment, Figure 4 As shown, the active driving wheel 21 is provided with a speed monitor 211 , the speed monitor 211 is electrically connected to the control module 212 , and the control module 212 is control-connected to the climbing motor 11 .

[0047] Thus, when the climbing device falls rapidly, the speed monitor 211 detects that the speed exceeds the preset value, and the speed monitor 211 transmits the signal to the control module 212, which controls the climbing motor 11 to slow down or stop. The speed monitor 211 and the control module 212 cooperate to prevent the climbing device from falling.

[0048] As a preferred embodiment, in order to keep the entire climbing device balanced, Figure 2 and 3 As shown, it also includes a passive wheel assembly 7, which is arranged below the driving wheel assembly 2 and is connected to the driving wheel assembly 2 through a connecting chain 6. The passive wheel assembly 7 has no driving force and is driven by the power of the driving wheel assembly 2 to achieve up and down movement on the tower 8.

[0049] In detail, the passive wheel assembly 7 includes a passive drive wheel 71 and a passive drive shaft 72. The passive drive wheel 71 is arranged on the passive drive shaft 72. The end of the passive drive shaft 72 is transmission-connected to the universal joint 4. The passive drive wheel 71 is spaced apart from the universal joint 4 through the passive drive shaft 72 to form a circular ring structure.

[0050] The passive drive wheel 71 moves up and down driven by the active drive wheel 21, generating friction between the passive drive wheel 71 and the outer wall of the tower 8. The passive drive wheel 71 rotates, driving the passive drive shaft 72 to rotate, and then power is transmitted through the universal joint 4, so that the entire passive drive wheel 71 moves evenly on the outer wall of the tower 8.

[0051] As a more preferred embodiment, the foot buckle frame includes two foot buckle frame units 31, the foot pedal 323 unit has a lug 32, the foot pedal 323 is arranged on the lug 32, the foot buckle frame unit 31 is semi-annular, and the openings are arranged oppositely, one of the lugs 32 is provided with a fixed buckle 321, and the other lug 32 is provided with a movable buckle 322 adapted to the fixed buckle 321.

[0052] The two semi-annular tripod frame units 31 are fixed to the periphery of the annular structure formed by the active drive shaft 22 and the universal joint 4, and the cooperation between the fixed buckle 321 and the movable buckle 322 facilitates disassembly.
