[0032] Example 1

[0033] See Figures 1 to 8 A climbing structure includes a frame having three first bodies 11 arranged in a C-shape. Each first body 11 has a first vertical plate 11a, and first end plates 11b are respectively provided at both ends of the first vertical plate 11a. The inner side of the first end plate 11b is arc-shaped. Adjacent first bodies 11 are connected by a connecting component.

[0034] The climbing device is arranged at the first main body 11 via an inner convex plate 21 and includes a tracked walking part 22. The tracked walking part 22 is connected to the inner convex plate 21 via a linkage assembly. The cylinder body of the inverted push cylinder 23 (including but not limited to electric cylinders and hydraulic cylinders; in this embodiment, a hydraulic cylinder is used) for pushing the tracked walking part to clamp the pole is movably connected (e.g., hinged) to the inner convex plate 21.

[0035] The push cylinder, track walking unit (track walking unit's walking motor, described below) is connected to the control unit.

[0036] In this embodiment, the connecting assembly includes a first connector 41 located on the inner bottom side (near the pole side) of the first main body (one end of the first connector 41 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw), a second connector 42 located on the inner top side (near the pole side) of the first main body (one end of the second connector 42 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw), a third connector 43 located on the outer bottom side (away from the pole side) of the first main body (one end of the third connector 43 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw), and a fourth connector 44 located on the outer top side (away from the pole side) of the first main body (one end of the fourth connector 44 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw).

[0037] In this embodiment, a baffle 45 is provided between the third connector 43 and the fourth connector 44. This design can form a shield, improving safety and connection stability.

[0038] In this embodiment, the tracked walking unit 22 includes a walking frame 22a. At both ends of the walking frame 22a are a track drive wheel 22c and a track driven wheel 22d driven by a walking motor 22b, respectively. A track 22e (preferably made of anti-slip rubber track, which has good climbing ability, is not easy to damage the pole, facilitates data collection, and improves the safety of the climbing structure) is arranged between the track drive wheel 22c and the track driven wheel 22d. Multiple auxiliary rotating wheels 22f are arranged in the walking frame near the pole side. The auxiliary rotating wheels 22f assist the track 22e in rotating and improve the clamping ability when the tracked walking unit clamps the pole.

[0039] In this embodiment, the linkage assembly includes two first linkages 51 located at the lower part of the track running section (located on both sides of the track running section), two second linkages 52 located at the upper part of the track running section (located on both sides of the track running section), and two actuating linkages 53 arranged at the track running section (located on both sides of the track running section); one end of the first linkage 51 is movably connected to the inner protrusion plate 21, and the other end is movably connected to the track running section 22; one end of the second linkage 52 is movably connected to the inner protrusion plate 21, and the other end is movably connected to the track running section 22; The actuating linkage 53 includes a third lower rod body 53a, which has a blind hole. Two blind hole notches are provided on the side of the blind hole (one located near the track running section and the other away from it). A third protrusion 53c is provided at the lower end of the third upper rod body 53b. The third protrusion 53c is installed at the blind hole. A limiting protrusion 53d is provided at the end of the third protrusion 53c, located at the blind hole notch (the third protrusion can move axially within the blind hole; the limiting protrusion prevents the third protrusion from dislodging). A spring 53f is installed on the three protruding pillars 53c (one end of the spring 53f is fixedly connected to the third lower rod 53a, and the other end is fixedly connected to the third upper rod 53b). The bottom of the third lower rod 53a is movably connected to the track walking part 22 (the third lower rod 53a is located outside the second connecting rod 52). The third upper rod 53b is movably connected to the movable body 53e. The movable body 53e is movably connected to the inner protruding plate (the movable body 53e can move up and down at the inner protruding plate, the inner protruding plate is provided with a slot, and the movable body 53e includes a movable body connecting rod with a U-shaped cross section). The connecting part 53e1, the movable body connecting part 53e1 is installed at the slot of the inner convex plate through two shafts 53e2 [one end of the shaft is connected to one side of the movable body connecting part, and the other end passes through the slot and is connected to the other side of the movable body connecting part]. Through this connection method, the movable body can move up and down. The movable body connecting part 53e1 is provided with two vertical connecting plates 53e3 on the side away from the inner convex plate, and a horizontal plate 53e4 is provided on the top of the two vertical connecting plates 53e3. The piston rod of the push cylinder 23 is connected to the movable body 53e (the horizontal plate connecting the movable body).

[0040] The following explains how the tracked running gear clamps the utility pole:

[0041] (I) Clamping process and spring action mechanism

[0042] Initially, spring 53f is in a pre-compressed state, providing basic clamping preload. When the piston rod extends, the moving body 53e moves downward, causing the third upper rod 53b to press down and compress spring 53f. As the piston rod moves downward, the third protrusion 53c presses down along the blind hole, further compressing the spring and increasing its elastic force. This elastic force is transmitted to the track travel part 22 through the third lower rod 53a, pushing the track to press firmly against the pole surface. The spring compression automatically adjusts with changes in pole diameter to ensure a constant clamping force for poles of different diameters (adaptive function). The limiting protrusion 53d at the blind hole notch prevents the third protrusion 53c from disengaging, forming a mechanical hard limit to prevent spring overload failure.

[0043] The state and stability of the push cylinder after clamping are guaranteed by a dual locking mechanism, namely, (1) hydraulic locking: the push cylinder is kept in the extended state and the piston rod position is locked by fluid pressure. (2) spring force maintenance: the spring is kept in the compressed state and continuously provides radial clamping force to counteract the loosening caused by unevenness or vibration of the pole surface.

[0044] Anti-interference capability: If an external impact causes the track to momentarily detach from the pole, the spring immediately releases its deformation energy, pushing the track back to its original position.

[0045] The stability advantages compared to existing technologies are shown in Table 1:

[0046] Table 1:

[0047]

[0048] (II) Reset Process and Spring Action

[0049] The piston rod retracts, the moving body 53e moves upward, the spring 53f gradually releases the compression, and the third upper rod 53b pulls the action link, so that the track travel part smoothly separates from the pole surface, avoiding sudden impact.

[0050] Spring return: After the piston rod is fully retracted, the spring returns to its pre-compressed state, preparing for the next clamping.

[0051] Through the linkage design of inverted push cylinder + preloaded spring + mechanical limit, the following are achieved: (1) Clamping force self-adaptation: spring deformation automatically matches the change in pole diameter; (2) Dual anti-loosening: hydraulic locking and spring elasticity complement each other; (3) Anti-vibration redundancy: spring dynamic compensation for instantaneous disengagement; (4) Smooth reset: avoids mechanism impact. This design fundamentally solves the shaking and displacement problems caused by a single drive source in traditional suspended detection devices, significantly improving the accuracy of detection data and operational safety.

[0052] Working process: First, the climbing structure is moved near the concrete pole to be inspected. The pole is then fitted into the climbing device through the opening (formed by the frame). The control unit controls the push cylinder to contact and clamp the tracked walking unit with the pole, ensuring the climbing structure is stably attached to it. Second, the control unit controls the tracked walking unit to start working, causing the climbing structure to move up or down along the pole.

[0053] The frame, linkage assembly, and tracked walking mechanism enable the device to maintain good stability when moving on the pole, effectively avoiding deviation or swaying and improving device safety.

[0054] Example 2: This example uses the climbing structure from Example 1.

[0055] See Figures 1 to 15 A robot for detecting corrosion on the surface of concrete poles includes a frame with three first bodies 11 arranged in a C-shape. Each first body 11 has a first vertical plate 11a and first end plates 11b are respectively provided at both ends of the first vertical plate 11a. The inner side of the first end plate 11b is arc-shaped. Adjacent first bodies 11 are connected by a connecting component.

[0056] The climbing device is arranged at the first main body 11 via the inner convex plate 21 and includes a tracked walking part 22. The tracked walking part 22 is connected to the inner convex plate 21 via a linkage assembly. The cylinder body of the inverted push cylinder 23 (including but not limited to electric cylinders and hydraulic cylinders; in this embodiment, a hydraulic cylinder is used) for pushing the tracked walking part to clamp the pole is movably connected (e.g., hinged) to the inner convex plate 21.

An actuating rack 33 is arranged between the two C-shaped sections 31. The outer side of the actuating rack 33 meshes with the outer gears. The inner side of the actuating rack 33 is limited by a limiting protrusion 34 arranged at the C-shaped section (the limiting protrusion 34 includes an upper limiting protrusion located at the upper C-shaped section and a lower limiting protrusion located at the lower C-shaped section).

[0059] In this embodiment, the connecting assembly includes a first connector 41 located on the inner bottom side (near the pole side) of the first main body (one end of the first connector 41 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw); a second connector 42 located on the inner top side (near the pole side) of the first main body (one end of the second connector 42 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw); a third connector 43 located on the outer bottom side (away from the pole side) of the first main body (one end of the third connector 43 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw); and a fourth connector 44 located on the outer top side (away from the pole side) of the first main body (one end of the fourth connector 44 is fixedly connected to the first end plate of the first main body on one side by a screw, and the other end is fixedly connected to the first end plate of the first main body on the other side by a screw). Adjacent first main bodies are fixedly connected by the connecting assembly.

[0060] In this embodiment, a baffle 45 is provided between the third connector 43 and the fourth connector 44. This design can form a shield, improving safety and connection stability.

[0061] In this embodiment, the tracked walking unit 22 includes a walking frame 22a. At both ends of the walking frame 22a are respectively provided a track drive wheel 22c and a track driven wheel 22d driven by a walking motor 22b. A track 22e (preferably a non-slip rubber track, which has good climbing ability, is not easy to damage the pole, facilitates data collection and improves robot safety) is provided between the track drive wheel 22c and the track driven wheel 22d. The track 22e has strong climbing ability. Multiple auxiliary rotating wheels 22f are provided in the walking frame near the pole side.

[0062] In this embodiment, the linkage assembly includes two first linkages 51 located at the lower part of the track running section (located on both sides of the track running section), two second linkages 52 located at the upper part of the track running section (located on both sides of the track running section), and two actuating linkages 53 arranged at the track running section (located on both sides of the track running section); one end of the first linkage 51 is movably connected to the inner protrusion plate 21, and the other end is movably connected to the track running section 22; one end of the second linkage 52 is movably connected to the inner protrusion plate 21, and the other end is movably connected to the track running section 22; The actuating linkage 53 includes a third lower rod body 53a, which has a blind hole. Two blind hole notches are provided on the side of the blind hole (one located near the track running section and the other away from it). A third protrusion 53c is provided at the lower end of the third upper rod body 53b. The third protrusion 53c is installed at the blind hole. A limiting protrusion 53d is provided at the end of the third protrusion 53c, located at the blind hole notch (the third protrusion can move axially within the blind hole; the limiting protrusion prevents the third protrusion from dislodging). A spring 53f is installed on the three protruding pillars 53c (one end of the spring 53f is fixedly connected to the third lower rod 53a, and the other end is fixedly connected to the third upper rod 53b).

The connecting part 53e1, the movable body connecting part 53e1 is installed at the slot of the inner convex plate through two shafts 53e2 [one end of the shaft is connected to one side of the movable body connecting part, and the other end passes through the slot and is connected to the other side of the movable body connecting part]. Through this connection method, the movable body can move up and down. The movable body connecting part 53e1 is provided with two vertical connecting plates 53e3 on the side away from the inner convex plate, and a horizontal plate 53e4 is provided on the top of the two vertical connecting plates 53e3. The piston rod of the push cylinder 23 is connected to the movable body 53e (the horizontal plate connecting the movable body).

[0063] The following explains how the tracked running gear clamps the utility pole:

[0064] (I) Clamping process and spring action mechanism

[0065] Initially, spring 53f is in a pre-compressed state, providing basic clamping preload. When the piston rod extends, the moving body 53e moves downward, causing the third upper rod 53b to press down and compress spring 53f. As the piston rod moves downward, the third protrusion 53c presses down along the blind hole, further compressing the spring and increasing its elastic force. This elastic force is transmitted to the track travel part 22 through the third lower rod 53a, pushing the track to press firmly against the pole surface. The spring compression automatically adjusts with changes in pole diameter to ensure a constant clamping force for poles of different diameters (adaptive function). The limiting protrusion 53d at the blind hole notch prevents the third protrusion 53c from disengaging, forming a mechanical hard limit to prevent spring overload failure.

[0066] The state and stability of the push cylinder after clamping are guaranteed by a dual locking mechanism, namely, (1) hydraulic locking: the push cylinder is kept in the extended state and the piston rod position is locked by fluid pressure. (2) spring force maintenance: the spring is kept in the compressed state and continuously provides radial clamping force to counteract the loosening caused by unevenness or vibration of the pole surface.

[0067] Anti-interference capability: If an external impact causes the track to momentarily detach from the pole, the spring immediately releases its deformation energy, pushing the track back to its original position.

[0068] The stability advantages compared to existing technologies are shown in Table 1:

[0069] Table 1:

[0070]

[0071] (II) Reset Process and Spring Action

[0072] The piston rod retracts, the moving body 53e moves upward, the spring 53f gradually releases the compression, and the third upper rod 53b pulls the action link, so that the track travel part smoothly separates from the pole surface, avoiding sudden impact.

[0073] Spring return: After the piston rod is fully retracted, the spring returns to its pre-compressed state, preparing for the next clamping.

[0074] Through the linkage design of inverted push cylinder + preloaded spring + mechanical limit, the following are achieved: (1) Clamping force self-adaptation: spring deformation automatically matches the change in pole diameter; (2) Dual anti-loosening: hydraulic locking and spring elasticity complement each other; (3) Anti-vibration redundancy: spring dynamic compensation for instantaneous disengagement; (4) Smooth reset: avoids mechanism impact. This design fundamentally solves the shaking and displacement problems caused by a single drive source in traditional suspended detection devices, significantly improving the accuracy of detection data and operational safety.

[0075] In this embodiment, an actuating rack and pinion motor is arranged on an actuating rack and pinion motor mounting base 61. A first pulley 62, a second pulley 63, and a third pulley 64 are provided at the bottom of the actuating rack and pinion motor mounting base 61. The first pulley 62 is connected to the actuating rack and pinion motor. The two outer gears located on the side of the C-shaped part away from the opening are the first outer gear 71 and the second outer gear 72 (there are four outer gears, arranged circumferentially between the C-shaped parts. In addition to the first outer gear 71 and the second outer gear 72, the other two are located on both sides of the opening of the C-shaped part. Preferably, the four outer gears are arranged at equal intervals). The first mounting shaft of the first outer gear 71 has a first lower extension section, and the first lower extension section is provided with a first lower extension section pulley 71a. The second mounting shaft of the second outer gear 72 has a second lower extension section, and the second lower extension section is provided with a second lower extension section pulley 72a. The belt 73 is wrapped around the first pulley 62, the second pulley 63, the first lower extension section pulley 71a, the second lower extension section pulley 72a, and the third pulley 64.

[0076] The rack and pinion motor rotates, driving the first pulley 62 to rotate, thus rotating the belt (see...). Figure 14 The second pulley 63 and the third pulley 64 are used to limit and tension the belt. As the belt rotates, it drives the first lower extension pulley 71a and the second lower extension pulley 72a to rotate. Therefore, the first outer gear 71 and the second outer gear 72 rotate, which drives the actuating rack 33 to rotate (the actuating rack 33 is a ring-shaped structure with an opening on one side and teeth on the outer side, which can rotate circumferentially without derailing). The rotation of the actuating rack 33 allows the camera to rotate circumferentially.

[0077] In this embodiment, the camera mount 35 has ear-shaped parts 351 at both ends. One end of each ear-shaped part 351 is connected to the camera mount 35, and the other end is equipped with a lamp body 36. The lamp body illuminates the camera, improving the imaging effect and enhancing the robot's detection accuracy. Correspondingly, the lamp body is connected to the control unit, and when the control unit controls the camera to work, the lamp body is turned on simultaneously.

[0078] The working process is as follows: First, the robot is moved near the concrete pole to be inspected. The pole is fitted into the robot through the opening (formed by the frame, C-section, and movable rack). The control unit controls the push cylinder to move, causing the tracked walking unit to contact and clamp the pole, ensuring the robot is stably attached to it. Second, the control unit controls the tracked walking unit to start working, moving the robot up or down along the pole. Simultaneously, the motor drives the movable rack, which in turn drives an industrial camera to capture 360° images of the pole. The industrial camera acquires image information in real time (the acquired image information is transmitted to the data processing system [control unit], where image processing and analysis algorithms determine whether there are cracks on the pole surface and whether the flange joints are corroded. If an anomaly is detected, the system marks and records the relevant information. The image processing and analysis part can refer to existing technology and is not an innovation of this invention, so it will not be described in detail). Finally, after the inspection is completed, the control system controls the tracked walking unit to return the robot to its initial position.

[0079] The robot, through its frame, linkage assembly, and tracked walking mechanism, maintains excellent stability while moving on utility poles, effectively avoiding deviation or swaying and improving robot safety. Compared to existing detection devices with poor stability, the robot can collect detection data more accurately, improving the reliability of the detection results. The robot adapts to different pole diameters.

[0080] Example 3

[0081] The basic scheme is the same as in Embodiment 2, except that a mounting port 352 is provided on the camera mounting body 35, and a first mounting block 351a is installed at the mounting port 352. One end of the arc-shaped ear 351 is detachably connected to the first mounting block 351a (the side of the first mounting block 351a is provided with a first mounting block opening 351a1, and the first mounting block 351a is provided with a first mounting block groove 351a2). The end of the ear 351 is inserted into the first mounting block opening 351a1, and two screws are arranged at the first mounting block groove 351a2. The screws pass downwards through the upper side of the first mounting block opening 351a1, the ear, and the lower side of the first mounting block opening 351a1 in sequence to fix the end of the ear. After installation, the top of the screw is located at the first... The lamp body 36 is detachably connected to the second mounting block 351b (the two ends of the ear are inserted into the groove 351a2 of the mounting block 351b, and the other end is detachably connected to the second mounting block 351b). The second mounting block 351b has a second mounting block opening 351b1 on its side and a second mounting block groove 351b2 on its top. Two screws are arranged in the groove 351b2, passing downwards through the upper side of the second mounting block opening 351b1, the ear, and the lower side of the second mounting block opening 351b1 to fix the ear end. After installation, the top of the screws is located within the groove 351b2 of the second mounting block. The lamp body 36 is detachably mounted on the second mounting block 351b (including but not limited to fixing with screws). The detachable connection between the two ends of the ear and the lamp body facilitates installation and disassembly, making maintenance convenient. If a single lamp body is damaged, only that lamp body needs to be replaced, not the entire lamp body, resulting in lower maintenance costs.
