[0044] The crawling device 200 includes a side beam 210, at least two walking mechanisms 220 and a wheeled shoe holding mechanism 230: wherein the side beam 210 is connected to one side of the fuselage frame 100; at least two walking mechanisms 220 are respectively arranged at the front and rear ends of the side beam 210, for crawling along the handrail rope 301. Of course, three walking mechanisms 220 can also be arranged, with one walking structure arranged at the center of the side beam 210; the wheeled shoe holding mechanism 230 includes a mounting base 231, a first roller assembly 232, a second roller assembly 233 and a first driving assembly 234, wherein, referring to Figure 4 The mounting base 231 is connected to the side beam 210, the first roller assembly 232 and the second roller assembly 233 are slidably arranged on the mounting base 231, and the sliding direction thereof is the width direction of the fuselage frame 100. The first driving assembly 234 is arranged on the mounting base 231, and is used to drive the first roller assembly 232 and the second roller assembly 233 to move toward or away from each other. The first roller assembly 232 includes a plurality of first rollers 2321, which are used to be pressed on one side of the handrail rope 301, and the second roller assembly 233 includes a plurality of second rollers 2331, which are used to be pressed on the other side of the handrail rope 301. At least one of the first roller 2321 and the second roller 2331 is provided with a driving motor 2332.

[0045] Among them, the width direction of the fuselage frame 100 is the left-right direction in the drawing, the length direction of the fuselage frame 100 is the front-back direction in the drawing, and the height direction of the fuselage frame 100 is the up-down direction in the drawing, which will not be described in detail later.

[0046] Furthermore, one or more wheeled shoe-holding mechanisms 230 may be provided along the length direction of the side beam 210 for clamping on both sides of the handrail rope 301 .

[0047] During use, the rollers of the two walking mechanisms 220 are pressed downward on the left and right handrails 301 to support the cable maintenance equipment, so that the cable maintenance equipment is stably loaded on the two handrails 301, so that it can stably move forward along the handrails 301; at the same time, the first driving assembly 234 drives the first roller assembly 232 and the second roller assembly 233 to move toward each other, the first roller 2321 of the first roller assembly 232 is pressed on the left or right side of the handrail 301, and the second roller 2331 of the second roller assembly 233 is pressed on the other side of the handrail 301, so that the wheeled shoe holding mechanism 230 is tightly held on the handrail 301. Then, the driving motor 2332 drives the first roller 2321 and / or the second roller 2331 to rotate, so that the cable maintenance equipment can be driven to move forward along the handrail 301. The bottom of the cable inspection equipment is usually loaded with a detection mechanism or a maintenance mechanism. The wheeled shoe holding mechanism 230 drives the cable inspection equipment to move forward along the handrail rope 301, thereby efficiently inspecting or repairing the cable 302.

[0048] Moreover, each crawling device 200 is provided with at least two wheeled shoe holding mechanisms 230. When the previous wheeled shoe holding mechanism 230 encounters an obstacle ahead, the first driving assembly 234 can drive the first roller assembly 232 and the second roller assembly 233 to move away from each other. At this time, the next wheeled shoe holding mechanism 230 drives the cable repair device to continue to move forward, so that the first roller assembly 232 and the second roller assembly 233 of the previous wheeled shoe holding mechanism 230 can effectively avoid the obstacle and move forward. After the previous wheeled shoe holding mechanism 230 passes the obstacle, the first driving assembly 234 drives the first roller assembly 232 and the second roller assembly 233 to move relative to each other and re-press onto the handrail rope 301.

[0049] In some embodiments, reference Figure 3 and Figure 4 , along the length direction of the side beam 210, that is, the front-to-back direction, the first roller 2321 and the second roller 2331 are arranged alternately in sequence. In this arrangement, the first roller 2321 and the second roller 2331 can be compactly pressed on the left and right sides of the handrail rope 301 by utilizing the gap between the two rollers, and there is a sufficiently large friction force between the first roller 2321 and the second roller 2331 and the handrail rope 301, and the driving motor 2332 can drive the first roller 2321 and / or the second roller 2331 to crawl along the handrail rope 301, so as to ensure that the cable maintenance equipment can move normally along the handrail rope 301.

[0050] Furthermore, the first roller assembly 232 includes two first rollers 2321, and the second roller assembly 233 includes a second roller 2331. The first roller 2321 and the second roller 2331 are alternately arranged, so that the second roller 2331 utilizes the gap between the two first rollers 2321, and the first roller 2321 and the second roller 2331 tightly hold the left and right sides of the handrail rope 301, and the second roller 2331 is provided with a driving motor 2332. With such arrangement, the first roller assembly 232 and the second roller assembly 233 have a simple overall structure and can be tightly clamped to the left and right sides of the handrail rope 301; and the second roller 2331 utilizes the gap between the two first rollers 2321 to be tightly pressed onto the side of the handrail rope 301, and the second roller 2331 is provided with a driving motor 2332. When the driving motor 2332 drives a second roller 2331 to rotate, it can stably drive the cable maintenance equipment to move along the handrail rope 301.

[0051] In some embodiments, the first roller 2321 and the second roller 2331 are respectively provided with annular flanges at both ends of the outer circumferential surface. With such arrangement, when the first roller 2321 and the second roller 2331 hold the handrail rope 301, the annular flanges at the upper and lower positions can effectively ensure that the handrail rope 301 is always located between the first roller 2321 and the second roller 2331, thereby ensuring that the cable maintenance equipment can move forward along the handrail rope 301.

[0052] In some embodiments, reference Figure 4 and Figure 5 The first driving assembly 234 includes a first driving member 2341, a first bidirectional screw rod 2342, a first sliding seat 2343 and a second sliding seat 2344, wherein the first bidirectional screw rod 2342 is arranged on the mounting base 231 along the width direction of the fuselage frame 100 and is rotatably connected to the mounting base 231. The first driving member 2341 can be a servo motor. The first driving member 2341 is arranged on one side of the mounting base 231. The driving shaft of the first driving member 2341 is transmission-connected to the first bidirectional screw rod 2342. Therefore, the first driving member 2341 is used to drive the first bidirectional screw rod 2342 to rotate. The first sliding seat 2343 and the second sliding seat 2344 are both slidably set on the mounting base 231 along the width direction of the fuselage frame 100. The first sliding seat 2343 is threadedly connected to a threaded section of the first bidirectional screw rod 2342, and the base of the first roller assembly 232 is connected to the first sliding seat 2343; the second sliding seat 2344 is threadedly connected to another threaded section of the second bidirectional screw rod 241, and the base of the second roller assembly 233 is connected to the second sliding seat 2344.

[0053] Specifically, if the first driving member 2341 drives the first bidirectional screw rod 2342 to rotate forward, the first bidirectional screw rod 2342 drives the first sliding seat 2343 and the second sliding seat 2344 to move toward each other, and the first roller assembly 232 and the second roller assembly 233 move toward each other synchronously, thereby clamping the left and right sides of the handrail rope 301; if the first driving member 2341 drives the first bidirectional screw rod 2342 to rotate reversely, the first bidirectional screw rod 2342 drives the first sliding seat 2343 and the second sliding seat 2344 to move away from each other, the first roller assembly 232 and the second roller assembly 233 move away from each other synchronously, and the first roller assembly 232 and the second roller assembly 233 release their clamping of the handrail rope 301.

[0054] In other possible embodiments, two first drive components 234 are provided, and the first drive components 234 can be a motor screw structure, or a drive structure such as a cylinder; wherein, one first drive component 234 is connected to the first roller component 232, and the other first drive component 234 is connected to the second roller component 233, thereby, the two first drive components 234 cooperate to push the first roller component 232 and the second roller component 233 to move toward each other or move away from each other.

[0055] In order to ensure that the walking mechanism 220 has the ability to overcome obstacles during the movement along the handrail rope 301, in the first embodiment, Figure 2 and Figure 3 The walking mechanism 220 includes a fixed base 221, a connecting rod 222, a shock absorber 223 and a walking roller 224, wherein the fixed base 221 is connected to the end of the side beam 210, one end of the connecting rod 222 is rotatably connected to the fixed base 221, and the other end is rotatably connected to the base of the walking roller 224, one end of the shock absorber 223 is rotatably connected to the fixed base 221, and the other end is rotatably connected to the base of the walking roller 224, and the shock absorber 223 is used to keep the walking roller 224 pressed against the handrail rope 301.

[0056] In a specific application process, when the walking mechanism 220 encounters an obstacle, the walking roller 224 overcomes the obstruction of the shock absorber 223, and the walking roller 224 adjusts its own height upward to pass over the obstacle in front. After the walking roller 224 passes over the obstacle, the walking roller 224 returns to its original position under the action of the shock absorber 223, so as to be pressed downward on the handrail rope 301.

[0057] In the second embodiment, the walking mechanism 220 includes a fixed base 221, a connecting rod 222, an electric push rod (not shown in the figure) and a walking roller 224, wherein the fixed base 221 is connected to the end or other position of the side beam 210, one end of the connecting rod 222 is rotatably connected to the fixed base 221, and the other end is rotatably connected to the base of the walking roller 224, the base of the electric push rod is rotatably connected to the fixed base 221, the push rod of the electric push rod is rotatably connected to the base of the walking roller 224, and the electric push rod is used to keep the walking roller 224 pressed against the handrail rope 301.

[0058] In a specific application process, when the walking mechanism 220 encounters an obstacle in front, the electric push rod pulls the walking roller 224 to rotate upward, and the walking roller 224 adjusts its own height to cross the obstacle in front. After the walking roller 224 crosses the obstacle, the walking roller 224 returns to its original position under the action of the electric push rod to press downward on the handrail rope 301.

[0059] In other possible embodiments, the walking mechanism 220 includes a fixed base 221, a connecting rod 222, an electric push rod, a shock absorber 223 and a walking roller 224, wherein the fixed base 221 is connected to the end or other position of the side beam 210, one end of the connecting rod 222 is rotatably connected to the fixed base 221, and the other end is rotatably connected to the base of the walking roller 224, the base of the electric push rod is rotatably connected to the fixed base 221, the push rod of the electric push rod is fixedly connected to one end of the shock absorber 223, and the other end of the shock absorber 223 is rotatably connected to the base of the walking roller 224, and the electric push rod is used to keep the walking roller 224 pressed against the handrail rope 301. The electric push rod and the shock absorber 223 can be installed in a swapped position.

[0060] In a specific application process, when the walking mechanism 220 encounters an obstacle in front, it determines the type of the obstacle in front. If the obstacle in front is low, the walking roller 224 overcomes the obstruction of the shock absorber 223, and the walking roller 224 adjusts its own height upward to cross the obstacle in front; if the obstacle in front is high, the electric push rod pulls the walking roller 224 to rotate upward, and the walking roller 224 adjusts its own height to cross the obstacle in front.

[0061] In addition, when the wheeled shoe-holding mechanism 230 encounters a high obstacle in front, each electric push rod pushes the walking roller 224 to rotate downward, and the height of the crawling device 200 is increased. Correspondingly, the height of the wheeled shoe-holding mechanism 230 is increased, so that the wheeled shoe-holding mechanism 230 can overcome the obstacle in front.

[0062] In a further embodiment, the crawling device 200 includes at least three walking mechanisms 220, which are sequentially arranged along the length direction of the side beam 210, for example, two walking mechanisms 220 are arranged at the front and rear ends of the side beam 210, and another walking mechanism 220 is arranged at the middle position of the side beam 210. It can be understood that when the front walking roller 224 is lifted upward to overcome an obstacle, the other two walking mechanisms 220 can stably support the crawling device 200, thereby ensuring that the crawling device 200 can stably move forward along the handrail rope 301.

[0063] In some embodiments, the wheeled shoe holding mechanism 230 further includes a second drive assembly (not shown in the figure), the second drive member 246 can be a motor screw structure, the second drive assembly is arranged on the side beam 210, and is connected to the mounting base 231 of the wheeled shoe holding mechanism 230, and the second drive assembly is used to drive the wheeled shoe holding mechanism 230 to move along the height direction of the fuselage frame 100. It can be understood that when the cable maintenance equipment is crawling along the handrail rope 301, the second drive assembly can drive the wheeled shoe holding mechanism 230 to adjust up and down, so that the handrail rope 301 can be maintained at the height position between the first roller 2321 and the second roller 2331, thereby ensuring the wheeled shoe holding mechanism 230 The tightening effect on the handrail rope 301, the cable maintenance equipment can stably crawl forward along the handrail rope 301.

[0064] In addition, when the wheeled shoe holding mechanism 230 encounters a higher obstacle in front, the second driving assembly drives the wheeled shoe holding mechanism 230 to adjust upward, so that the wheeled shoe holding mechanism 230 can go over the obstacle in front.

[0065] In some embodiments, reference Figure 2 , Figure 3 and Figure 6 The two side beams 210 are slidably arranged on the fuselage frame 100 along the width direction of the fuselage frame 100. The cable maintenance equipment also includes a variable pitch drive mechanism 240.

Thus, the two side inspection mechanisms 400 cooperate to inspect the surface defects of the cable 302.

[0070] Specifically, the side detection mechanism 400 includes an upper swing frame 420, a lower swing arm 430, a first electric push rod 440, a second electric push rod 450 and a first detection module 410, wherein a mounting seat 211 is provided on the outer side of the side beam 210, one end of the upper swing frame 420 is rotatably connected to the side beam 210, and the rotation center axis is arranged parallel to the side beam 210, the main body of the first electric push rod 440 is rotatably connected to the mounting seat 211, and the power rod of the first electric push rod 440 is rotatably connected to the upper swing frame 420, thereby, the first electric push rod 440 is used to push the upper swing frame 420 to rotate around a rotating axis parallel to the side beam 210. One end of the lower swing arm 430 is rotatably connected to the other end of the upper swing frame 420, and the rotation center axis is arranged parallel to the side beam 210. The main body of the second electric push rod 450 is rotatably connected to the upper swing frame 420, and the power rod of the second electric push rod 450 is rotatably connected to the lower swing arm 430. The first detection module 410 is arranged at the other end and / or other position of the lower swing arm 430.

When the side detection mechanism 400 is detecting the cable 302, the power rod of the first electric push rod 440 is extended, the upper swing frame 420 is rotated downward, and the power rod of the second electric push rod 450 is extended, and the lower swing arm 430 is rotated downward, thereby adjusting the position and posture of the side detection mechanism 400, and then the defects on the surface of the cable 302 can be fully detected.

[0072] In some embodiments, the cable repair equipment further includes an intermediate detection mechanism 500, which includes a second detection module 510 and a folding bracket 520. The folding bracket 520 is rotatably arranged on the intermediate frame, and the central axis of rotation is perpendicular to the side beam 210. The second detection module 510 is provided with the folding bracket 520. When the cable repair equipment is being transported, the folding bracket 520 can be folded upward and attached to the bottom of the intermediate frame, thereby facilitating the transportation of the cable repair equipment. When the cable repair equipment is in use, the folding bracket 520 can be rotated downward to unfold the folding bracket 520, and the second detection module 510 can inspect the upper side of the cable 302.
