Description

Technical Field

[0001] This utility model relates to the technical field of climbing operations, specifically to a climbing mechanism for a ring-shaped work platform suitable for buildings with variable diameters. Background Technology

[0002] Wind turbine towers and utility poles, among other pole-like structures, often require climbing for inspection or spraying and rust removal. To avoid safety accidents that can easily occur during manual maintenance, a type of climbing robot has been developed for this purpose.

[0003] When performing operations on buildings with varying diameters, robots capable of adapting to different rod diameters are selected. For example, Chinese utility model patent application CN202221874181.7 discloses an automatic climbing and maintenance device for large-diameter variable rods, which overcomes the technical problem of excessive space occupation caused by the traditional method of using cylinders as variable diameter drive by using a scissor frame as a drive support.

[0004] However, as is well known, the surface of a variable-diameter building is necessarily inclined. When the scissor lift drives the climbing wheels inward, the driving direction of the scissor lift and the direction of the reaction force on the scissor lift are not consistent. When the ring platform is lifting, especially when the diameter of the building changes significantly, the force on the scissor lift in the non-outward direction will be greater. Therefore, under such long-term unbalanced force conditions, the scissor lift is prone to deviation, breakage, or even damage, resulting in the ring platform's lifting function being unreliable and its adaptability being limited.

[0005] Therefore, in order to ensure the stable and reliable lifting capacity of the ring platform, this application proposes a more balanced force-bearing climbing mechanism for ring work platforms suitable for variable-diameter buildings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a climbing mechanism for a ring-shaped work platform suitable for buildings with varying diameters.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a climbing mechanism for a ring-shaped work platform suitable for variable-diameter buildings, comprising several scissor frames, a climbing unit rotatably mounted on the top end of the scissor frames, and a cylinder for driving the extension and retraction of the scissor frames;

[0008] It also includes a transverse guide rail for slidingly mounting each of the climbing units. The transverse guide rails are all fixedly connected to the annular platform. The other end of the transverse guide rail is provided with a vertical guide rail. The two handles of the scissor frame away from the climbing unit are respectively rotatably connected to the vertical guide rail and slidably connected to it. The cylinder is mounted on the vertical guide rail, and the top end of the cylinder is rotatably connected to a slidable handle on the scissor frame.

[0009] Preferably, the transverse guide rail is further provided with a sliding groove, and the shaft of the scissor bracket near one end of the transverse guide rail is slidably connected in the sliding groove.

[0010] Preferably, the transverse guide rail is fixedly connected to the bottom of the annular platform, and the scissor frame and climbing unit are both located at the bottom of the transverse guide rail.

[0011] Preferably, the climbing unit includes a slider and a wheel, the slider being slidably connected to a transverse guide rail, and the wheel being rotatably connected to the end of the slider.

[0012] Preferably, the climbing unit further includes a rotating rod and a wheel frame, the rotating rod being rotatably connected to the end of the slider, the wheel frame being fixedly connected to the rotating rod, and both wheels being rotatably mounted on the wheel frame.

[0013] Preferably, the climbing unit further includes a drive belt, which is disposed between the two wheels to drive the two wheels to rotate synchronously.

[0014] Preferably, the transverse guide rails comprise at least three.

[0015] Preferably, the climbing unit is connected to the transverse guide rail via a pressure detection unit, and also includes a control unit. The output of the control unit is electrically connected to the input of the cylinder and the input of the climbing unit, and the output of the pressure detection unit is electrically connected to the input of the control unit.

[0016] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped working platform suitable for variable-diameter buildings, including the above-mentioned climbing mechanism, and also including a ring-shaped platform.

[0017] Preferably, the annular platform is composed of several arc-shaped monorails spliced ​​together, and the transverse guide rail is detachably connected to the arc-shaped monorails.

[0018] Compared with the prior art, this utility model provides a climbing mechanism for a ring-shaped work platform suitable for buildings with variable diameters, which has the following advantages:

[0019] This climbing mechanism for a circular work platform suitable for variable-diameter buildings offers a more reliable force balance during movement compared to current solutions that directly place the climbing unit at the top of the scissor lift. It reduces the likelihood of the scissor lift or vertical guide rail shifting, breaking, or being damaged due to the misalignment between the scissor lift's outward direction and the reaction force exerted on the climbing unit on the variable-diameter building. This mechanism ensures sufficient load-bearing capacity for the circular platform and reliable lifting functionality without requiring excessive use of scissor lifts and climbing units.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see Figure 1-3 This utility model provides the following technical solution: a climbing mechanism for a ring-shaped work platform suitable for variable-diameter buildings, including several scissor frames 1, climbing units 2 rotatably mounted on the top end of the scissor frames 1, and cylinders 3 for driving the extension and retraction of the scissor frames 1; it also includes transverse guide rails 4 for slidingly mounting each climbing unit 2, the transverse guide rails 4 are all fixedly connected to the ring-shaped platform A, and the other end of the transverse guide rails 4 is provided with a vertical guide rail 5, the two handles 11 at the end of the scissor frame 1 away from the climbing unit 2 are respectively rotatably connected and slidably connected to the vertical guide rail 5, the cylinder 3 is mounted on the vertical guide rail 5, and the top end of the cylinder 3 is rotatably connected to the slidable handle 11 on the scissor frame 1.

[0032] As an optional implementation of this utility model, the ring platform A is existing technology. It can be a split type, a clamp type structure, or a combination of multiple arc-shaped monorails. The fixed connection between the transverse guide rail 4 and the ring platform A is preferably a detachable connection, such as a threaded connection. This allows for the selection of a ring platform A with a suitable inner diameter when dealing with buildings of different diameters. Similarly, the climbing unit 2 is also an existing technical solution. It can be a tire with an electromagnet or a suction cup type, etc. This technical solution is not specifically limited. It should be understood that this technical solution is an improvement on the installation method of the climbing mechanism on the ring platform A, rather than an improvement on the ring platform A or the climbing unit 2. Among them, the ring platform A is also the moving track for the robot to move around the variable diameter building for painting, rust removal and other tasks. When it is necessary to change the working height of the robot on the variable diameter building, the climbing unit 2 is controlled to drive the ring platform A to move up and down on the variable diameter building. In addition, the scissor frame 1 is also a common scissor frame 1. In this technical solution, the installation method of the two handles 11 of the scissor frame 1 is as follows: the first handle 111 is rotatably connected to the vertical guide rail 5, and the second handle 112 is slidably connected to the vertical guide rail 5.

[0033] When it is necessary to raise or lower the circular platform A, multiple cylinders 3 are controlled to extend and retract, so that the slidable second handle 112 slides on the vertical guide rail 5. This allows the entire scissor frame 1 to extend and retract, thereby driving the climbing unit 2 to approach or move away from the surface of the variable-diameter building. At the same time, the climbing unit 2 is controlled to move on the surface of the variable-diameter building, so that the climbing unit 2 can always maintain contact with the surface of the variable-diameter building, and achieve a stable raising and lowering process for the entire circular platform A. Since the climbing unit 2 is slidably installed with the transverse guide rail 4, the climbing unit 2 is also guided by the transverse guide rail 4 during the process of the scissor frame 1 driving the climbing unit 2 to approach or move away from the variable diameter building. Compared with the current technical solution of directly setting the climbing unit 2 at the top end of the scissor frame 1, the climbing unit 2 in this technical solution has a more reliable force balance state when moving. It is less likely that the scissor frame 1 or the vertical guide rail 5 will be deflected, broken or even damaged due to the inconsistency between the top direction of the scissor frame 1 and the direction of the reaction force on the climbing unit 2 on the variable diameter building. It can ensure that the ring platform A has sufficient load capacity and ensure the reliable lifting function of the ring platform A without using too many scissor frames 1 and climbing units 2.

[0034] With the above structure, compared with the current technical solution of directly setting the climbing unit 2 at the top end of the scissor frame 1, the climbing unit 2 has a more reliable force balance state when moving. It is less likely that the scissor frame 1 or the vertical guide rail 5 will be deflected, broken or even damaged due to the inconsistency between the top direction of the scissor frame 1 and the direction of the reaction force on the climbing unit 2 on the variable diameter building. It can ensure that the ring platform A has sufficient load capacity and ensure the reliable lifting function of the ring platform A without using too many scissor frames 1 and climbing units 2.

[0035] like Figure 2-3 As shown, the transverse guide rail 4 is also provided with a slide groove 41, and the shaft 12 of the scissor bracket 1 near one end of the transverse guide rail 4 is slidably connected in the slide groove 41.

[0036] As an optional embodiment of this utility model, shaft 12 should be considered as a rotating shaft located near the transverse guide rail 4 along the length of the scissor frame 1, used to connect the two connecting rods on the scissor frame 1. Based on the sliding engagement between the climbing unit 2 and the transverse guide rail 4, the extension and retraction of the scissor frame 1 further engages with the transverse guide rail 4, thus further improving the stability of the ring platform A during lifting, especially during ascent.

[0037] like Figure 1-2 As shown, the transverse guide rail 4 is fixedly connected to the bottom of the ring platform A, and the scissor frame 1 and climbing unit 2 are both located at the bottom of the transverse guide rail 4.

[0038] As an optional implementation of this utility model, since the spraying and rust removal robot usually moves above the ring platform A, it has the advantages of being easier to assemble and disassemble and having a better working field of vision. Therefore, the above structure makes it less likely for the robot to be obstructed during its movement and for its field of vision to be blocked during spraying and rust removal operations.

[0039] like Figure 3 As shown, the climbing unit 2 includes a slider 21 and a wheel 22. The slider 21 is slidably connected to the transverse guide rail 4, and the wheel 22 is rotatably connected to the end of the slider 21.

[0040] As an optional embodiment of this utility model, the wheel 22 is a common technical solution in the prior art, such as a tire with an electromagnet.

[0041] like Figure 3 As shown, the climbing unit 2 also includes a rotating rod 23 and a wheel frame 24. The rotating rod 23 is rotatably connected to the end of the slider 21, and the wheel frame 24 is fixedly connected to the rotating rod 23. Both wheels 22 are rotatably mounted on the wheel frame 24.

[0042] As an optional embodiment of this utility model, since some existing ring-shaped work platforms have two wheels 22 in each climbing unit 2, the wheel frame 24 is configured to rotate with the slider 21. This makes it easier for all wheels 22 to fit the surface of the variable-diameter building during climbing and descending, ensuring that the climbing unit 2 has sufficient climbing stability and static stability. Of course, there can be multiple wheels 22, and this technical solution does not specifically limit this.

[0043] like Figure 3 As shown, the climbing unit 2 also includes a transmission belt 25, which is located between the two wheels 22 to drive the two wheels 22 to rotate synchronously.

[0044] As an optional implementation of this utility model, in the prior art, the wheels 22 are usually driven by a servo motor, so multiple wheels 22 in the same climbing unit 2 can rotate synchronously through the transmission belt 25.

[0045] like Figure 1 As shown, the transverse guide rails 4 consist of at least three rails that are evenly distributed in a ring on the annular platform A.

[0046] As an optional embodiment of this utility model, multiple transverse guide rails 4 are evenly distributed in a ring on the ring platform A, so that the entire ring platform A is subjected to more balanced forces when it is raised and lowered.

[0047] like Figure 4 As shown, the climbing unit 2 is connected to the transverse guide rail 4 through the pressure detection unit 6, and also includes a control unit 7. The output end of the control unit 7 is electrically connected to the input end of the cylinder 3 and the input end of the climbing unit 2, and the output end of the pressure detection unit 6 is electrically connected to the input end of the control unit 7.

[0048] As an optional implementation of this utility model, the pressure detection unit 6 can be a pressure sensor, and a detection threshold can be preset. When the ring platform A is raised or lowered, the pressure detection unit 6 will detect the tension or pressure between the climbing unit 2 and the scissor frame 1. When the threshold is exceeded, the cylinder 3 will be controlled to start running, thereby driving the scissor frame 1 to push out or retract, in order to compensate for the changing pressure value, so that the force between the scissor frame 1 and the climbing unit 2 is always kept within a stable range, ensuring that the ring platform A can be stably attached to the variable diameter building during the entire operation.

[0049] Example 2:

[0050] A ring-shaped work platform suitable for variable-diameter buildings includes the climbing mechanism of Embodiment 1, and also includes a ring-shaped platform A, which is composed of several arc-shaped monorails spliced ​​together, and the transverse guide rail 4 is detachably connected to the arc-shaped monorails.

[0051] As an optional implementation of this utility model, when dealing with buildings with different maximum diameters, a ring platform A with a suitable inner diameter can be selected for construction.

[0052] The working principle and usage process of this utility model are as follows: When it is necessary to lift and move the ring platform A, multiple cylinders 3 are controlled to extend and retract, so that the slidable second handle 112 slides on the vertical guide rail 5. This allows the entire scissor frame 1 to extend and retract, thereby driving the climbing unit 2 to approach or move away from the surface of the variable-diameter building. At the same time, the climbing unit 2 is controlled to move on the surface of the variable-diameter building, so that the climbing unit 2 can always maintain contact with the surface of the variable-diameter building, and realize that the entire ring platform A has a stable lifting process.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
