The first layer of arc-shaped plates, the second layer of arc-shaped plates, and the third layer of arc-shaped plates are fixedly connected to each other, and the fourth layer of arc-shaped plates and the fifth layer of arc-shaped plates are fixedly connected to each other. The hydraulic cylinder bodies 5-1 of the multiple movable hydraulic cylinders 5 are fixed to the third arc plate between the second and third arc plates via cylinder seats.

Preferably, the multiple movable hydraulic cylinders are in four groups, and the hydraulic cylinder bodies 5-1 are evenly distributed on the second and third arc plates, while the hydraulic cylinder rods 5-2 of the multiple movable hydraulic cylinders are evenly distributed between the third and fourth arc plates.

[0016] Drive wheels 6, with their rotation axes arranged vertically, are rotatably connected to the middle of the first, second, fourth, and fifth arc-shaped plates. These drive wheels are connected to a rotation drive device and can rotate under the drive of the device. In one embodiment of this invention, the rotation drive device includes two drive wheels located on the first and second arc-shaped plates, their rotation axes connected by an upper connecting rod. The upper connecting rod is connected to an upper rotary bearing, which is installed on the first and second arc-shaped plates respectively. The rotating shafts of the two drive wheels located on the fourth and fifth arc-shaped plates are connected by a lower connecting rod on the rotating shaft fixing plate 12, which is fixedly connected to the fourth and fifth arc-shaped plates respectively. The rotating drive mechanism is a dual-axis motor fixed on the third arc-shaped plate. The upper motor shaft of the dual-axis motor, which serves as the rotational motion output end of the rotating drive mechanism, is fixedly connected to the upper connecting rod, and the lower motor shaft of the dual-axis motor is fixedly connected to the lower connecting rod.

[0017] An upper locking mechanism 3 is provided at each of the left and right ends between the first and second arc-shaped plates, and a lower locking mechanism 7 is provided at each of the left and right ends between the fourth and fifth arc-shaped plates. Each upper and lower locking mechanism includes a locking hydraulic cylinder 4. The end of the cylinder rod of each locking hydraulic cylinder, which is arranged horizontally, is fixedly connected to the lower part of a first vertical rod arranged vertically. The lower part of the first vertical rod, the second vertical rod arranged parallel to the first vertical rod, and the lower part of a driven wheel shaft 8 are all fixedly connected to a lower rotating plate, and the upper parts are all fixedly connected to a lower rotating plate. The upper rotating plate is fixedly connected, and a driven wheel 9 is rotatably connected to the upper and lower ends of the driven wheel shaft, respectively. The upper and lower ends of the second vertical rod are rotatably connected to the corresponding arc-shaped plates (rotary bearings can be installed on the arc-shaped plates, and the upper and lower ends of the second vertical rod can be inserted into the bearings, or other existing rotatable connection structures can be used). That is, the upper and lower ends of the second vertical rod of the upper locking mechanism are rotatably connected to the first and second arc-shaped plates, respectively, and the upper and lower ends of the second vertical rod of the lower locking mechanism are rotatably connected to the fourth and fifth arc-shaped plates, respectively. The driven wheels of the upper and lower locking mechanisms can be engaged or disengaged from the guide tube frame to be cleaned, which is installed inside the carrier body, under the drive of the locking hydraulic cylinder.

[0018] A work terminal interface 10 is installed on the first layer of the arc plate. The work terminal interface 10 is used to connect work equipment, such as cleaning equipment, detection equipment, etc. The specific equipment can be connected according to the work needs, and the connection can be made by bolts.

[0019] Preferably, the movable hydraulic cylinder and the locking hydraulic cylinder 4 are connected to the controller 2 via signal lines.

[0020] The working process of this vehicle is as follows:

[0021] First, with the cooperation of the construction personnel, the carrier is placed in the corresponding position on the guide pipe rack 11 to be cleaned, such as... Figure 3 As shown, after being placed in this position, the locking hydraulic cylinder 4 retracts, and the upper locking mechanism 3 and the lower locking mechanism 7 are locked under the drive of the locking hydraulic cylinder 4, fixing the carrier in the current designated position. After the carrier is fixed in the current position, the working terminal installed at the working terminal interface 10 performs the operation (the working terminal is a high-pressure water spray gun during cleaning and a testing device during testing). At the same time as the operation begins, the drive wheel 6 moves in a circle under the power provided by the rotation drive device, and the driven wheel of the upper and lower locking mechanisms also moves in a circle under the power provided by the drive wheel, so that the entire carrier moves in a circle on the surface of the waterproof sleeve. The carrier moves in a circle while working, completing a 360-degree circular operation on the surface of the waterproof sleeve.

[0022] After the cleaning of this location is completed, the moving hydraulic cylinder 5 drives the entire carrier to move up and down for operation. When moving down at this location, the original upper and lower locking mechanisms remain locked. Figure 5 As shown), the upper locking mechanism 3 remains locked, the lower locking mechanism 7 is released, and the hydraulic cylinder rod of the moving hydraulic cylinder 5 moves downward, causing the lower locking mechanism 7 to move downward. The fourth and fifth arc-shaped plates move downward, and when they reach the designated position, the lower locking mechanism 7 locks. Figure 5 (As shown), then the upper locking mechanism 3 is released, the hydraulic cylinder rod of the moving hydraulic cylinder 5 moves downward, and the upper locking mechanism 3 also moves downward under the drive of the moving hydraulic cylinder 5. The first, second, and third layer arc plates move downward and lock at the designated position. At this time, both the upper and lower locking mechanisms are locked at this position, and the entire vehicle is moved to the designated position. Figure 5 (As shown), and then perform a 360-degree circular operation again through the operation terminal installed at the operation terminal interface. This operation is repeated in a loop.

[0023] When moving upwards from this position, the lower locking mechanism 7 remains locked, while the upper locking mechanism 3 is released. The hydraulic cylinder rod of the moving hydraulic cylinder 5 moves upwards, causing the upper locking mechanism 3 to move upwards as well. The first, second, and third layer arc-shaped plates move upwards until they reach their designated positions, at which point the upper locking mechanism 3 locks. Then, the lower locking mechanism 7 releases, and the hydraulic cylinder rod of the moving hydraulic cylinder 5 moves upwards. The lower locking mechanism 7 also moves upwards under the influence of the moving hydraulic cylinder 5. The fourth and fifth layer arc-shaped plates move upwards until they reach their designated positions, at which point the lower locking mechanism 7 also locks. At this point, both the upper and lower locking mechanisms are locked at this position, and the entire vehicle has been moved to the designated location. Then, a 360-degree circular operation is performed again via the work terminal installed at the work terminal interface. This cycle is repeated continuously.

[0024] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
