Description

Technical Field

[0001] This utility model relates to the field of magnetic adsorption wall-climbing robot technology, and in particular to a roller tensioning mechanism for a magnetic adsorption wall-climbing robot. Background Technology

[0002] Magnetic adsorption wall-climbing robots are specialized robots, primarily used in harsh, dangerous, and extreme working conditions to perform specific tasks such as detection, inspection, welding, and grinding on magnetically conductive walls. Currently, they are widely used in steel-structure-based production and construction industries, including nuclear power, petrochemicals, construction, fire services, and shipbuilding. Engineering applications of magnetic adsorption wall-climbing robots require addressing a series of challenges, including adsorption, driving, steering, obstacle crossing, adaptation to surfaces with small curvatures, load on working components, and even automatic control. Currently, continuous optimization efforts are underway to address these aspects. The adsorption tracks in magnetic adsorption wall-climbing robots exhibit extremely strong adsorption forces during operation. Existing tensioning structures generally provide limited tensioning support in such high-intensity adsorption environments; they are either overly complex and costly, or simple and lack stable tensioning capabilities.

[0003] For example, Chinese Patent Publication No. CN209274753U discloses a roller tensioning mechanism and a magnetic adsorption wall-climbing robot, relating to the technical field of magnetic adsorption wall-climbing robots. A roller tensioning mechanism, suitable for magnetic adsorption wall-climbing robots, includes a tensioning suspension, a tensioning wheel, and a tensioning adjustment assembly. One end of the tensioning suspension is rotatably connected to the body of the magnetic adsorption wall-climbing robot. The tensioning wheel is rotatably mounted on the tensioning suspension and is used to engage with the adsorption track of the magnetic adsorption wall-climbing robot. The tensioning adjustment assembly can drive the tensioning suspension to rotate relative to the body, and the tensioning suspension drives the tensioning wheel to tension the adsorption track, thereby adjusting the tensioning force of the tensioning wheel on the adsorption track.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The tensioning mechanism of the above-mentioned technical solution is not convenient for adjusting the spacing of the support rollers, so it is difficult to apply to magnetic adsorption wall-climbing robots with different spans, thus reducing its practicality. Utility Model Content

[0006] The purpose of this invention is to provide a tensioning mechanism for the support rollers of a magnetic adsorption wall-climbing robot. By setting a support mechanism, the tension of the support roller mechanism can be adjusted, and the distance between the two tensioning rollers can be adjusted, thus making it suitable for magnetic adsorption wall-climbing robots with different spans, thereby improving the practicality of this invention.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A roller tensioning mechanism for a magnetically adsorbed wall-climbing robot includes:

[0009] The mounting plate has a telescopic and adjustable support mechanism installed on its top. The support mechanism has a roller mechanism installed on its top. The roller mechanism includes a mounting shell, and adjustable tension wheels are provided on both sides of the mounting shell.

[0010] The aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism includes a support mechanism comprising a support shell fixedly connected to the mounting plate, and a support column slidably connected to the inner wall of the support shell.

[0011] In the aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism, a positioning pin for fixing the support column is installed on the top of the side of the support shell, and a plurality of positioning grooves are equidistantly arranged on the side of the support column corresponding to the position of the positioning pin.

[0012] In the aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism, a threaded column is rotatably mounted on the inner wall of the mounting shell via a bearing seat. A bearing seat is threaded onto the threaded column, and the end of the bearing seat is rotatably connected to the tensioning wheel via a bearing.

[0013] In the aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism, both sides of the threaded sleeve are fixedly connected to limit sliders, and the inner wall of the mounting shell is provided with a limit groove that matches the limit slider at the position corresponding to the limit slider.

[0014] In the aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism, the limiting slider on the side near the limiting groove moves through the limiting groove and extends into the interior of the limiting groove, where it slides in connection with the inner wall of the limiting groove.

[0015] In the aforementioned magnetic adsorption wall-climbing robot's roller tensioning mechanism, an adjusting handle is rotatably mounted at the center of the top of the mounting shell, and an active bevel gear is fixedly connected to the bottom of the adjusting handle. A driven bevel gear that meshes with the active bevel gear is mounted at the end of the threaded column and at a position corresponding to the active bevel gear.

[0016] This utility model has at least the following beneficial effects:

[0017] The magnetic adsorption wall-climbing robot tensioning mechanism provided by this utility model, by setting a support mechanism, can realize the adjustment of the tension of the roller mechanism, and facilitate the adjustment of the distance between the two tensioning rollers, so as to be applicable to magnetic adsorption wall-climbing robots with different spans, thus improving the practicality of this utility model.

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Please refer to Figures 1 to 4As shown, an embodiment of this utility model provides a roller tensioning mechanism for a magnetic adsorption wall-climbing robot, comprising: a mounting plate 1, an adjustable support mechanism 2 mounted on the top of the mounting plate 1, a roller mechanism 3 mounted on the top of the support mechanism 2, the roller mechanism 3 comprising a mounting shell 301, and adjustable tensioning wheels 3011 provided on both sides of the mounting shell 301.

[0032] By adopting the above technical solution, not only can the tension of the roller mechanism 3 be adjusted by setting the support mechanism 2, but it is also convenient to adjust the distance between the two tensioning rollers 3011, so that it can be applied to magnetic adsorption wall climbing robots with different spans, thus improving the practicality of this utility model.

[0033] Please refer to Figures 1 to 4 As shown, the support mechanism 2 includes a support shell 201 fixedly connected to the mounting plate 1. A support column 2011 is slidably connected to the inner wall of the support shell 201. By slidingly setting the support column 2011 inside the support shell 201, the support height of the mounting shell 301 can be adjusted, thereby facilitating the adjustment of the tensioning force of the tensioning wheel 3011. A positioning pin 202 for fixing the support column 2011 is installed on the top of the side of the support shell 201. The side of the support column 2011 and the position corresponding to the positioning pin 202 are provided with equidistant openings. Several positioning slots 2021 are arranged and are engaged with corresponding positioning pins 202 by positioning pins 202, thereby facilitating the limiting and fixing of the adjusted support column 2011. A threaded column 3021 is rotatably mounted on the inner wall of the mounting shell 301 via a bearing seat 3022. The bearing seat 3022 is threadedly connected to the threaded column 3021. The end of the bearing seat 3022 is rotatably connected to the tensioning wheel 3011 via a bearing. The tensioning wheel 3011 can be adjusted by the thread action of the threaded column 3021 and the threaded sleeve 302.

[0034] Please refer to Figures 1 to 4As shown, both sides of the threaded sleeve 302 are fixedly connected to limit sliders 3023. A limit groove 3024, matching the limit slider 3023, is provided on the inner wall of the mounting housing 301 at a position corresponding to the limit slider 3023. The side of the limit slider 3023 closest to the limit groove 3024 moves through the limit groove 3024 and extends into the interior of the limit groove 3024, slidingly connecting with the inner wall of the limit groove 3024. By setting the limit slider 3023 and the limit groove 3024, the threaded sleeve 302 is limited, thereby increasing the threaded sleeve's stability. The stability of the tensioning wheel 3011 is adjusted by 302. An adjusting handle 303 is rotatably installed at the center of the top of the mounting housing 301. The bottom of the adjusting handle 303 is fixedly connected to the driving bevel gear 3031. The end of the threaded column 3021 and the position corresponding to the driving bevel gear 3031 are installed with a driven bevel gear 3032 that meshes with the driving bevel gear 3031. The driving bevel gear 3031 is rotated by adjusting the handle 303, and the threaded column 3021 is driven to rotate under the meshing action of the driven bevel gear 3032 and the driving bevel gear 3031.

[0035] The working principle of this utility model is as follows: First, by loosening the positioning pin 202 and disengaging it from the corresponding positioning groove 2021, the support column 2011 slides and adjusts on the inner wall of the support shell 201. After adjustment, the positioning pin 202 is engaged in the corresponding positioning groove 2021, thereby adjusting the height of the tension wheel 3011. This allows for adjustment of the chain tension of the wall-climbing robot. Furthermore, by rotating the driving bevel gear 3031 through the adjusting handle 303, and under the meshing action of the driven bevel gear 3032 and the driving bevel gear 3031, the threaded column 3021 is driven to rotate. Under the action of the threaded sleeve 302, the tension wheel 3011 on the side of the threaded sleeve 302 is moved, thereby adjusting the distance between the two tension wheels 3011. This makes it suitable for magnetic adsorption wall-climbing robots with different spans, thus improving the practicality of this utility model.
