[0033] like Figure 1 As shown, a detachable climbing gearbox includes a power box 1 with a climbing gear 11 inside. In this embodiment, the climbing gear 11 serves as the core load-bearing component and includes a hub 111. Several keyways 112 are machined evenly and at intervals on the inner wall of the hub 111. The keyways 112 allow the hub 111 to receive power via a key connection, ensuring the synchronicity and stability of power transmission. In addition, spokes 113 extend radially outward from the outer side of the hub 111, serving as intermediate connecting members and having multiple weight-reducing holes 113a. In this embodiment, eight weight-reducing holes 113a are provided, evenly distributed circumferentially around the hub 111. The weight-reducing holes 113a effectively reduce the overall weight of the gear and decrease the moment of inertia, thereby improving the responsiveness of the gear's starting, stopping, and speed change. Furthermore, several teeth 114 are circumferentially distributed at intervals along the outer edge of the spokes 113. In this embodiment, there are eleven teeth 114, which are distributed circumferentially along the spokes 113. In other embodiments, other numbers of teeth 114 may be provided as needed.

[0034] like Figure 2-4 As shown, the power box 1 also includes a housing 14, which is used to accommodate and support various functional components and has a clearance groove 141. Mounting bases 142 are symmetrically arranged on opposite sides of the clearance groove 141, and a limiting rod 143 is provided between the two mounting bases 142. The two ends of the limiting rod 143 are rotatably connected to the two mounting bases 142 respectively. In addition, two clamping wheels 144 are respectively provided on the two mounting bases 142, and the two clamping wheels 144 are rotatably connected to their respective mounting bases 142. More specifically, the positions of the two clamping wheels 144 and the limiting rod 143 are precisely designed. The two clamping wheels 144, the limiting rod 143, and the side walls of the two mounting bases 142 together enclose an installation space, which can stably constrain the power box 1 when it is installed in place.

[0035] In terms of power, a power supply 15 is installed inside the housing 14, which supplies power to the entire machine. The drive motor 16, as the power source, is electrically connected to the power supply 15, and a planetary reducer 17 is connected to its output shaft. In this embodiment, the planetary reducer 17 is a right-angle reducer, with its input and output shafts arranged at a right angle to facilitate the conversion of power transmission direction. Simultaneously, the coordinated arrangement of the drive motor 16 and the right-angle reducer makes the entire power housing 1 structure more compact, saving overall space. More specifically, the output shaft of the drive motor 16 is connected to the input end of the planetary reducer 17, while the output end of the planetary reducer 17 is connected to the hub 111 of the aforementioned climbing gear 11 via a key or other means, thereby efficiently and reliably transmitting the rotational power of the drive motor 16 to the climbing gear 11.

[0036] like Figure 5-6 As shown, a car 2 for carrying personnel or materials is detachably connected to the top of the power unit 1. In this embodiment, the detachable connection is a hinge. Specifically, the top of the power unit 1 is provided with a connecting lug 12 corresponding to the hinge support 22, and the hinge support 22 and the connecting lug 12 are hinged together by a hinge shaft 13. This design allows the car 2 and the power unit 1 to rotate relative to each other to adapt to changes in the slope of the tower guide rail, and can be easily separated when maintenance or transportation is required, realizing the modular independence of the power unit and the personnel unit.

[0037] At least one set of guide components 21 is provided on the frame of the car 2. Specifically, in this embodiment, four sets of guide components 21 are provided, and the four sets of guide components 21 are arranged in a spaced and symmetrical manner at the four key support parts of the car 2. Through the symmetrical arrangement of the four sets of guide components 21, uniform support and constraint points are formed around the perimeter. This layout can effectively balance the torques that may be generated in various directions during the operation of the equipment, significantly suppress the swaying and torsion of the car 2, ensure its extreme stability during the lifting process, and provide a solid and reliable platform for high-altitude operations.

[0038] Specifically, such as Figure 7As shown, each guide component 21 includes a mounting base 211. In this embodiment, the mounting base 211, serving as the mounting and load-bearing foundation, is made of high-strength material to ensure its reliability under heavy loads and high-frequency use. A support plate 212 is fixedly mounted on the mounting base 211. This support plate 212 serves as the skeleton of the entire guide structure, providing stable support for other moving parts. Two guide wheels 213, rotatably connected to the support plate 212, are spaced apart on the support plate 212. Setting the number of guide wheels 213 to two optimizes the force distribution and ensures the smooth operation of the car 2. More specifically, the support plate 212 is provided with two axles 214. One end of each axle 214 is fixed to the support plate 212 (e.g., by welding or bolting), and the other end extends in a direction perpendicular to the plane of the support plate 212 and passes through the guide wheels 213. In this embodiment, the guide wheels 213 are sleeved on the outside of the axles 214 and rotatably connected to them. The axles 214 provide the mounting base for the guide wheels 213. The guide wheel 213 has a shoulder 213a, the cross-sectional profile of which is configured such that its diameter gradually decreases with distance from the supporting upright plate 212, forming a unique arc-shaped guide structure. This design allows the guide wheel 213 to fit very precisely onto the guide post 31 (mentioned later). Figure 13-14 As shown in the figure, this effectively limits the lateral sway and wobble of the equipment during operation, thereby improving the guiding accuracy.

[0039] Meanwhile, to ensure that the guide wheel 213 will not accidentally detach from the axle 214 in the axial direction, a limiting ring 215 is provided at the end of the axle 214 away from the support plate 212. The outer diameter of the limiting ring 215 is larger than the inner diameter of the central shaft hole of the guide wheel 213, thereby forming an effective mechanical barrier and playing the role of axial positioning and safety protection.

[0040] like Figure 8 As shown, a fall arrestor 23 is installed on the top of the car 2 to provide fall protection. Specifically, the fall arrestor 23 includes a brake 231, with an output gear 232 connected to the output shaft of the brake 231. The output gear 232 meshes with a brake gear 233, driving it to move synchronously. Further, fall arrestor gears 234 are coaxially spaced on the brake gear 233, and the fall arrestor gears 234 can rotate synchronously under the drive of the brake gear 233. When the equipment stalls and falls, the fall arrestor 23 can be quickly triggered, locking the fall arrestor gears 234 rapidly through the gear meshing relationship, thereby immediately stopping the equipment.

[0041] like Figure 9-10As shown, to further enhance safety, at least one support plate 24 is also provided on the top of the car 2. In this embodiment, four support plates 24 are arranged along the four corners of the car 2. Limiting plates 25 are slidably connected to the support plates 24 through clearance holes. Specifically, a sliding rod 241 is provided in the clearance hole. The sliding rod 241 passes through the clearance hole and can slide along the support plate 24. One end of the return spring 242 sleeved on the rod abuts against the support plate 24, and the other end is connected to the limiting plate 25. By setting the return spring 242, the impact energy is absorbed, generating a buffering or limiting effect.

[0042] like Figure 11-13 As shown, the present invention also provides a climbing system, including a detachable climbing box and guide posts 31 as described above. In this embodiment, two guide posts 31 are provided, spaced apart. To enhance the overall structural rigidity, several connecting rods 32 are provided between the two guide posts 31, with both ends of each connecting rod 32 firmly connected to the two guide posts 31, forming a stable truss-type support frame. Furthermore, the outer circumferential shape of the guide post 31 precisely matches the contour of the shoulder 213a of the aforementioned guide wheel 213, forming a stable rolling contact pair to ensure that the guide wheel 213 can roll smoothly along the surface of the guide post 31, thereby achieving precise guidance.

[0043] Specifically, such as Figure 12 As shown, a connector 32a is installed on some or all of the connecting rods 32. One end of the connector 32a is fixed to the connecting rod 32, and the other end (i.e., the end away from the connecting rod 32) is connected to a climbing rack 4. The climbing rack 4 meshes with the aforementioned climbing gear 11, thereby integrating the climbing rack 4, guide post 31, and connecting rod 32 into a high-rigidity integral guide rail unit. This combined guide rail structure, through rigid connection and truss design, significantly improves load-bearing capacity and resistance to bending and torsion, making it particularly suitable for applications such as high-altitude climbing equipment where high rigidity and stability of the guide rail are required.

[0044] like Figure 14 As shown, the climbing rack 4 includes a mounting groove 41. In this embodiment, the mounting groove 41 has a rectangular cross-section with an opening on one side. The mounting groove 41 is made of a high-strength material (e.g., high-strength alloy steel or heat-treated high-quality carbon structural steel) to ensure the necessary mechanical strength and durability as the mounting and load-bearing foundation for the entire rack. Inside the mounting groove 41, several teeth 42 are spaced apart. These teeth 42, as key components directly involved in the meshing transmission, are typically made of a material with superior wear resistance than the mounting groove 41, or their meshing surfaces are hardened through quenching or nitriding to significantly improve their wear resistance and service life.

[0045] Meanwhile, to further extend the length of the rack to adapt to different travel requirements, the climbing rack 4 of this invention can adopt a modular splicing design. Specifically, the number of mounting slots 41 is at least two sets, and these mounting slots 41 can be arranged sequentially end to end through precision positioning interfaces (not shown in the figure) provided at their ends. In this embodiment, the number of mounting slots 41 is set to ten sets, and in other embodiments, other numbers of mounting slots 41 can be selected for splicing according to the actual height of the power tower. This modular design allows the rack to be flexibly extended in length according to actual needs, and when a local tooth 42 is worn excessively, only the specific mounting slot 41 section can be replaced without scrapping the entire rack, greatly reducing the later maintenance and usage costs.

[0046] like Figure 15 As shown, the mounting groove 41 has a closed side 41a and an open side 41b, a design that facilitates the installation and maintenance of internal components. At both ends of the closed side 41a, there are first horizontally extending extensions 41a', which are arranged parallel to the main body of the mounting groove 41. Similarly, at both ends of the open side 41b, there are second horizontally extending extensions 41b', whose extension direction is also parallel to the mounting groove 41. This symmetrically extended structural design forms a stable guiding and load-bearing frame. In actual use, the clamping wheel 144 on the aforementioned power box 1 rolls against the first extension 41a', and the limiting rod 143 rolls against the second extension 41b' (the specific cooperation relationship between the two is as follows...). Figure 5 As shown, the climbing power box 1 effectively restricts the degree of freedom in the direction perpendicular to the mounting slot 41 by rolling and abutting each other, while ensuring the precise guidance and anti-overturning stability of the power box 1 and the entire climbing equipment during operation.

[0047] This application achieves adaptive operation and rapid maintenance of the equipment on variable-slope tracks through a hinged, detachable connection between the car and the power unit. Simultaneously, the integration of a guide assembly with wheel shoulders ensures precise guidance and stability during the climbing process, and incorporates fall arrestors and mechanical limit mechanisms to construct a multi-layered safety protection system, ultimately achieving a comprehensive improvement in the safety, adaptability, and maintainability of high-altitude operations.

[0048] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
