[0032] In order to facilitate the rotation of the mounting frame 3, a driving component 1 for driving the mounting frame 3 to rotate is provided on the rope climbing detection robot 1, and the driving component 1 includes a motor 10 and a gear 11. The motor 10 is fixed to the outer wall of the rope climbing detection robot 1, and the gear 11 is coaxially fixedly connected to the output shaft of the motor 10. An outer gear ring 12 is fixedly connected to the mounting frame 3, and the outer gear ring 12 includes two half circles, and the two half circles are respectively fixedly connected to the two unit frames 4. When the two unit frames 4 are spliced ​​into the mounting frame 3, the two half circles are spliced ​​into the outer gear ring 12, and the gear 11 is used to mesh with the spliced ​​outer gear ring 12.

[0033] In another embodiment, the driving component 2 can also be driven by a roller, that is, a roller is used to replace the gear 11, and the roller is used to abut against the outer wall of the mounting frame 3. The rotation of the roller can drive the mounting frame 3 to rotate.

[0034] In this embodiment, the repair mechanism includes two sliding frames 13 , and the two sliding frames 13 are slidably connected to two unit frames 4 , respectively. The unit frames 4 are provided with a driving component 2 for driving the sliding frames 13 to slide.

[0035] The second driving assembly includes a second motor 14 and a screw rod 15 . The screw rod 15 is rotatably connected to the unit frame 4 . The second motor 14 is used to drive the screw rod 15 to rotate, and the rotation of the screw rod 15 drives the sliding frame 13 to slide.

[0036] In another embodiment, the second driving component may also be a cylinder.

[0037] In this embodiment, the repair mechanism further includes a laser cutting gun 16 , two laser cutting guns 16 are fixedly connected to one sliding frame 13 , and the shortest connection line between the two laser cutting guns 16 is arranged along the length direction of the cable 2 .

[0038] When the damaged part of the protective cover is detected by the climbing rope detection robot 1, the laser cutting gun 16 is moved to a suitable position by rotating the mounting frame 3 and sliding the sliding frame 13, and then the laser cutting gun 16 is turned on, and at the same time, the climbing rope detection robot 1 is moved along the length direction of the cable 2 to cut a strip groove at the damaged part of the protective cover, and then the mounting frame 3 is rotated, and the two laser cutting guns 16 can separate the damaged part of the protective cover from the protective cover, and then continue to adjust the position of the laser cutting gun 16 to cut another strip groove at the relative position of the first strip groove at the damaged part of the protective cover. At this time, the damaged part of the protective cover can be separated from the protective cover and fall off.

[0039] In this embodiment, in order to prevent the damaged part of the protective sleeve from falling off after cutting, an air nozzle 19 is fixedly connected to the unit frame 4, and an air pump 20 is fixedly connected to the sliding frame 13. The air pump 20 is connected to the air nozzle 19 through a hose. The air nozzle 19 is used for the downward cutting position of the laser cutting gun 16.

[0040] After the damaged part of the protective sleeve is cut off, a new protective sleeve needs to be filled, so the repair mechanism also includes two mounting plates 17, and the two mounting plates 17 are respectively arranged on the two sliding frames 13. The mounting plates 17 are connected with protective half sleeves 18 through connecting components. The protective half sleeves 18 on the two mounting plates 17 are arranged relatively to each other, and then the two sliding frames 13 are close to each other, driving the two mounting plates 17 to approach each other, so that the two protective half sleeves 18 can be embedded in the gap cut by the laser cutting gun 16 on the cable 2.

[0041] In addition, in order to fix the two protective half-sheaths 18 embedded in the notches cut by the laser cutting gun 16 on the cable 2 to form a protective sheath, two hot melt guns 21 are installed on the sliding frame 13 where the laser cutting gun 16 is not installed, and the shortest connecting line of the two hot melt guns 21 is arranged along the length direction of the cable 2. After the protective half-sheath 18 on the mounting plate 17 is embedded in the notch cut by the laser cutting gun 16 on the cable 2, the two protective half-sheaths 18 are hot-melted together by the hot melt gun 21, and the two protective half-sheaths 18 are hot-melted to the bridge cable 2 by the hot melt gun 21 at the same time.

[0042] In order to make the width of the protective half sleeve 18 adapt to the distance between the two laser cutting guns 16 and the two hot melt guns 21, the distance between the two laser cutting guns 16 and the distance between the two hot melt guns 21 are equal to or slightly larger than the width of the protective half sleeve 18 on the sliding frame 13.

A rack 24 is fixedly connected to the mounting plate 17 along its length direction. Gear two 23 is fixedly connected to the output shaft of motor three 22. Gear two 23 and rack 24 are meshingly connected.

[0045] In another embodiment, the drive component three may also be a screw rod 15 transmission component.

[0046] Reference Figure 1 and Figure 4 In this embodiment, due to the limitations of the distance between the two laser cutting guns 16 and the distance between the two hot melt guns 21, it is necessary to provide a slide groove 25 on the mounting plate 17 for the laser cutting gun 16 and the hot melt gun 21 to pass through, so as not to affect the sliding of the mounting plate 17 while ensuring that the distance between the two laser cutting guns 16 and the two hot melt guns 21 can adapt to the width of the protective half-cover 18.

[0048] In addition, in order to facilitate the operation of the repair mechanism, a plurality of cameras 29 are installed on the mounting frame 3 along its circumference, and the cameras 29 face the repair mechanism.

[0049] The implementation principle of the bridge cable 2 repair device of the embodiment of the present application is as follows: when in use, first install the two unit frames 4 on the cable climbing detection robot 1, and make the mounting frame 3 formed by the two unit frames 4 sleeved on the cable 2, then adjust the position of the guide rod 8 to insert the guide rod 8 into the annular groove 5, and then move the cable climbing detection robot 1. When the damaged part of the protective sleeve is detected by the cable climbing detection robot 1, the laser cutting gun 16 is moved to a suitable position by rotating the mounting frame 3 and sliding the sliding frame 13, and then the laser cutting gun 16 is turned on, and at the same time, the cable climbing detection robot 1 is moved along the length direction of the cable 2. Move to cut a strip groove on the damaged part of the protective sleeve, and then use the mounting frame 3 to rotate, the two laser cutting guns 16 can separate the damaged part of the protective sleeve from the protective sleeve, and then continue to adjust the position of the laser cutting gun 16, and cut another strip groove at the relative position of the first strip groove on the damaged part of the protective sleeve. At this time, the damaged part of the protective sleeve can be separated from the protective sleeve and fall off, and then slide the mounting plate 17 to move the protective half sleeve 18 on the mounting plate 17 to the notch position, and then slide the sliding frame 13 to embed the protective half sleeve 18 into the notch, and then use the hot melt gun 21 to fix the protective half sleeve 18.
