[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] See Figures 1 to 9 As shown, the utility model is a column climbing device, which includes a frame assembly 10 and a climbing assembly 20.

[0034] The frame assembly 10 is in a ring shape that can be arranged around the column A. Figure 2 、 Figure 3 As shown, the frame assembly 10 in this embodiment is formed by six connecting plates 1 connected in the first position. If the connecting plates 1 are long straight plates, the resulting frame assembly 10 forms a regular polygon; if the connecting plates 1 are curved plates, the resulting frame assembly 10 forms a circle. The number of connecting plates 1 can be adjusted according to actual needs, but generally, at least three connecting plates 1 are used in the first position.

[0035] To facilitate processing and connection, two adjacent connecting plates 1 are connected by rivets via connecting blocks 14. To allow the frame assembly 10 to be mounted on the column A, the frame assembly 10 is provided with at least one pivot point 101 and a snap-fit point 102. The pivot point 101 allows the frame assembly 10 to be opened, while the snap-fit point 102 allows the frame assembly 10 to be closed and mounted on the column A.

[0036] The pivoting position 11 is located at the joint position of two connecting plates 1. Figure 3 As shown, in this embodiment, two pivoting positions 101 are provided, that is, the two ends of one connecting plate 1 are connected to the adjacent connecting plate 1 through pivots.

[0037] In order to facilitate opening of the frame assembly 10, the buckle position 12 is located on the connecting plate 1 away from the pivot position 11. Figure 4As shown, in this embodiment, the snap-fit position 12 includes: a first plate 11 and a second plate 12 that can be plugged into each other to form a connecting plate 1, and a connecting pin 13, the first plate 11 has a slot 111, and the second plate 12 has an insertion end 121 that can be inserted into the slot 111, and the first plate 11 and the second plate 12 are connected by the connecting pin 13 passing through the slot 111 and the insertion end 121.

[0038] When it is necessary to operate, the buckle position 102 on the frame assembly 10 is opened, and the frame assembly 10 is rotated along the pivot position 101 to open at the buckle position 12. The double pivot positions 101 in this embodiment can allow the frame assembly 10 to open to a larger angle.

[0039] To achieve uniform climbing force, at least three sets of climbing assemblies 20 should be provided, and these climbing assemblies 20 are evenly distributed in a ring shape on the frame assembly 10. Each set of climbing assemblies 20 includes: a swing mechanism 3 connected to the frame assembly 10, a roller mechanism 4, and a tensioning mechanism 5. The roller mechanism 4 has a roller driven by a roller motor. The tensioning mechanism 5 is provided on the swing mechanism 3. The tensioning mechanism 5 drives the swing mechanism 3 to swing, driving the rollers in the roller mechanism 4 close to the surface of the column A.

[0040] Specifically, the swing mechanism 3 comprises a positioning plate 31 fixedly connected to the frame assembly 10, a swing plate 32 pivotally connected to the roller mechanism 4, and a hinged rod 33 connected between the positioning plate 31 and the swing plate 32. The positioning plate 31 is provided with a number of evenly distributed strip holes 311. Bolts passing through the strip holes 311 secure the positioning plate 31 to the lower end of the corresponding connecting plate 1. Depending on the diameter of the column A, the strip holes 311 can be positioned differently for connection, ensuring that the area enclosed by the climbing assembly 20 matches the diameter of the column A.

[0041] In this embodiment, the swing mechanism 3 adopts a parallelogram linkage mechanism, which can make the swing plate 32 produce a stable horizontal swing. Specifically, two groups of four hinge rods 33 are provided between the positioning plate 31 and the swing plate 32.

[0042] In this embodiment, the tensioning mechanism 5 utilizes a motor-driven screw mechanism, specifically, a telescopic rod 51 that is retractable and extendable. The two ends of the tensioning mechanism 5 are movably connected between the positioning plate 31 and the swing plate 32, and are located diagonally on the parallelogram linkage of the swing mechanism 3. As a result, when the telescopic rod 51 of the tensioning mechanism 5 retracts and contracts, it pushes the swing plate 32 to swing horizontally relative to the positioning plate 31.

[0043] The present invention also includes an electronic telescopic ruler 8, which is disposed between the positioning plate 31 and the swing plate 32. The extension and contraction of the electronic telescopic ruler 8 is linked to the extension and contraction of the tensioning mechanism 5. This allows the electronic telescopic ruler 8 to measure the extension and contraction of the tensioning mechanism 5. The measured data can be fed back to the device's control module to ensure that the extension and contraction of the tensioning mechanism 5 matches the required pressure, thus preventing the tensioning mechanism 5 from failing to provide sufficient tension, causing the entire device to fall along the column A.

[0044] The swing mechanism 3 also includes an auxiliary roller 9, which does not serve as a drive wheel. The auxiliary roller 9 is hinged to the positioning plate 31 or the hinge rod 33. A guide groove can be provided in the middle of the auxiliary roller 9, allowing the auxiliary roller 9 to act as a guide wheel and climb linearly along the protrusion on the column A.

[0045] The roller mechanism 4 comprises a fixed plate 41 pivotally connected to the swing mechanism 3 and a roller unit 42 mounted on the fixed plate 41. The roller unit 42 has a left arm 421 and a right arm 422. Rollers 40 and roller motors 401 driving the rollers 40 are symmetrically mounted horizontally at the ends of the left and right arms 421 and 422. Each roller 40 is driven by an independent roller motor 401, allowing each roller to function as a drive wheel and generate sufficient climbing force.

[0046] In order to make the rollers 40 on the left and right sides of the roller unit 42 fit tightly against the surface of the column A, there should be a certain angle between the left arm 421 and the right arm 422. The size of the angle is adapted to the diameter of the column A, and the angle range can usually be selected between 120°-150°.

[0047] In addition, in order to increase the friction force, the upper and lower ends of the fixed plate 41 are respectively installed with parallel roller units 42. Each set of roller mechanisms 4 has four rollers 40, each of which serves as a driving wheel to provide sufficient climbing force for the entire device.

[0048] The column A is usually not a standard cylinder, and usually has a certain taper. Therefore, as the present invention climbs, the diameter of the column A gradually decreases. If the tensioning mechanism 5 is not adjusted accordingly, the present invention may experience insufficient friction and be unable to continue climbing. In order to overcome this problem, the present invention is provided with a pressure sensor 50 between the swing mechanism 3 and the roller mechanism. That is, a pressure sensor 50 is provided between the fixed plate 41 and the swing mechanism 3, and the pressure sensor 50 is electrically connected to the tensioning mechanism 5. Specifically, a swing shaft 321 is provided on the side of the swing plate 32 of the swing mechanism 3 close to the roller mechanism 4, and a swing seat 322 is sleeved on the swing shaft 321. The swing seat 322 is fixedly connected to a force-bearing plate 323. The pressure sensor 50 is located between the force-bearing plate 323 and the fixed plate 41 of the roller mechanism 4. This allows the roller mechanism 4 to be pivotally connected to the swing mechanism 3 via the swing shaft 321 and the swing seat 322. Simultaneously, the pressure exerted by the swing mechanism 3 on the roller mechanism 4 acts on the pressure sensor 50. When the pressure value detected by the pressure sensor 50 is less than a set value, the control unit activates the tensioning mechanism 5, increasing the extension length of the telescopic rod 51, thereby exerting sufficient pressure on the roller mechanism 4. Thus, during climbing, the present invention automatically adjusts the tensioning force based on the diameter of the column A, ensuring that the roller 40 exerts sufficient pressure on the surface of the column A, achieving stable climbing without falling.

[0049] In order to monitor the column A and the equipment mounted on the column, the utility model adopts CCD detection, that is, a plurality of cameras 6 are provided on the frame assembly 10, and the lenses of these cameras 6 are adjusted in direction as needed. During the climbing process of the utility model, the column and related equipment are photographed and archived until the detection is completed.

[0050] See Figure 10 As shown, in order to realize wireless control, the present invention can also set a wireless signal transmission device 100 on the frame assembly 10 to realize real-time transmission of the climbing speed and the image captured by the camera 6.

[0051] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
