Abstract
Description

[0003] To ensure the proper functioning of streetlights and the lifespan of the light poles, they require inspection, maintenance, and cleaning. These operations include polishing, repainting, and cleaning the poles. To perform these operations, workers use specialized tools to climb to the top of the light poles. They then inspect, maintain, and replace the bulbs, or clean the bulbs and lampshades. Once the work is complete, they descend the poles. To perform these operations, workers use climbing tools to reach the top of the poles and then crawl down from the top, performing the work while climbing. This requires workers to climb the poles, making the operation complex and posing a threat to their personal safety. To address this, workers can use a crawling device to drive a tool up the poles, allowing them to begin work once they reach their work location. However, the clamping force between the crawling device and the pole body is weak, making it prone to falling, making it impossible for the crawling device to reach its work location.

[0023] See also Figures 1 to 2 and Figure 5 , the figure shows the preferred structure of the clamping device in this embodiment. As shown in the figure, the clamping device includes: a clamping drive mechanism 1 and a clamping roller 2. Among them, the clamping drive mechanism 1 is used to be set on the first side of the body 81 of the pole climbing robot 8, and the clamping drive mechanism 1 is connected to the clamping roller 2. Specifically, the pole climbing robot 8 includes: a body 81, and the clamping drive mechanism 1 is set on the first side of the body 81.
[0024] The clamping roller 2 is parallel to the body 81 . More specifically, the clamping roller 2 is parallel to a first side of the body 81 , and the rod is clamped between the clamping roller 2 and the body 81 .
[0025] The clamping drive mechanism 1 is used to drive the clamping roller 2 to move toward the main body 81 so that the clamping roller 2 and the main body 81 clamp the rod.
[0026] It can be seen that in this embodiment, the clamping drive mechanism 1 is arranged on the first side of the main body 81 of the pole-climbing robot 8, that is, the clamping drive mechanism 1 and the pole-climbing robot 8 are relatively fixed, the clamping roller 2 is parallel to the main body 81, and the clamping drive mechanism 1 drives the clamping roller 2 to move toward the main body 81 so that the clamping roller 2 and the main body 81 clamp the rod body.

[0027] See also Figures 1 to 2 、 Figure 5 In the above embodiment, the clamping drive mechanism 1 includes: a support frame 11, a drive cylinder 12 and a sliding member 13. The support frame 11 is connected to the first side of the body 81. The drive cylinder 12 is arranged along the length direction of the support frame 11 ( Figure 1The drive cylinder 12 is disposed within the support frame 11 (as viewed from left to right in the figure). Specifically, the length of the support frame 11 is perpendicular to the first side of the main body 81. The drive end of the drive cylinder 12 is retractable along the length of the support frame 11. The drive end of the drive cylinder 12 is connected to a sliding member 13, which is connected to the clamping roller 2. The drive cylinder 12 is used to drive the sliding member 13 to slide along the length of the support frame 11, thereby driving the clamping roller 2 to move. Specifically, the sliding of the sliding member 13 drives the clamping roller 2 to slide along the length of the support frame 11, causing the clamping roller 2 to approach the main body 81, thereby causing the clamping roller 2 and the main body 81 to clamp the rod body. The structure of the clamping drive mechanism 1 is simple and easy to implement.

The two optical bars 14 are arranged side by side, and both extend along the length direction of the support tube 111.
[0034] See also Figure 1 and Figure 2 The sliding member 13 includes two driving plates 131, a first connecting plate 132, a second connecting plate 133, and two clamping sliders 134. The two driving plates 131 are arranged in parallel and extend along the length direction of the support frame 11. One of the driving plates 131 is parallel to the support cylinder 111 and is placed above the top of the support cylinder 111. Specifically, the driving plate 131 is placed between the top of the support cylinder 111 and the optical bar 14 above it. There is a certain gap between the driving plate 131 and the top of the support cylinder 111, and there is also a certain gap between the driving plate 131 and the optical bar 14 above it. Another driving plate 131 is parallel to the support cylinder 111 and is placed below the bottom of the support cylinder 111. Specifically, the driving plate 131 is placed between the bottom of the support cylinder 111 and the optical bar 14 below it. In addition, there is a certain gap between the driving plate 131 and the bottom of the support cylinder 111, and there is also a certain gap between the driving plate 131 and the optical bar 14 below.
[0035] The first connecting plate 132 is vertically clamped between the first ends of the two driving plates 131 ( Figure 1 The first connecting plate 132 blocks the first ends of the two driving plates 131, and the first connecting plate 132 is connected to the driving end of the driving cylinder 12.
[0036] The second connecting plate 133 is provided at the second end ( Figure 2 The right end (as shown) faces one side of the rod body, and the second connecting plate 133 is connected to the second ends of both drive plates 131. That is, the second connecting plate 133 is not located at the end surface of the second ends of the two drive plates 131, but is located on one side of the two drive plates 131. The second connecting plate 133 is perpendicularly connected to the end of the clamping roller 2 so that the clamping roller 2 is parallel to the body 81.
[0037] The two clamping sliders 134 correspond one-to-one to the two driving plates 131 , and each clamping slider 134 is arranged on the corresponding driving plate 131 . Furthermore, the two clamping sliders 134 correspond one-to-one to the two optical bars 14 , and each clamping slider 134 is slidably connected to the corresponding optical bar 14 .
[0038] The driving cylinder 12 is arranged inside the support frame 11, and the driving cylinder 12 is fixed as a whole. The extension and contraction of the driving end of the driving cylinder 12 drives the first connecting plate 132 to slide. The first connecting plate 132 drives the two clamping sliders 134 to slide along the corresponding optical bar 14 through the two driving plates 131.

[0041] In specific implementation, the limit positions of contraction and extension of the driving cylinder 12 are determined by the size of the rod body, and the clamping force is provided by the rodless cavity of the driving cylinder 12.
[0042] It can be seen that in this embodiment, the drive cylinder 12 drives the sliding member 13 to slide along the optical bar 14, driving the clamping roller 2 to move, so that the clamping roller 2 is close to the main body 81 and clamps the rod body. The structure of the clamping drive mechanism 1 is simple and easy to implement. In addition, the sliding member 13 slides along the optical bar 14, which not only ensures the linear motion of the clamping roller 2, but also can resist the bending moment generated by the larger clamping force. In this way, the clamping drive mechanism 1 can provide a larger force output and can also ensure that the sliding member 13 performs linear motion.
[0043] See also Figures 1 to 3 、 Figure 5 In the above embodiments, the clamping device further comprises a detection device 4. The detection device 4 is disposed in the body 81 and is used to detect the clamping force applied by the clamping roller 2 to the rod.
