[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a robotic arm 1 and a detector 2, with the detector 2 fixedly mounted on the robotic arm 1; It also includes: The base 3 is fixedly mounted at the bottom of the robotic arm 1. Several fixed posts 4 with equal rounded corners are distributed on the outer ring wall of the base 3. Movable rods 5 are movably inserted into the fixed posts 4. A movable frame 6 is fixedly mounted at one end of the movable rod 5. Reinforcing frames 7 are fixedly mounted on both the upper and lower side walls of the movable rod 5, and are fixedly connected to the movable frame 6. The reinforcing frames 7 can improve the structural strength at the connection between the movable rod 5 and the movable frame 6. Two rotating rods 8 are rotatably mounted on the movable frame 6 via bearings. Rotating wheels are fixedly sleeved at the ends of the rotating rods 8. 9. An anti-slip sleeve 20 is fixedly fitted on the rotating wheel 9. Several limiting strips 21 are distributed on the inner wall of the anti-slip sleeve 20 with rounded corners. The limiting strips 21 are set in the strip-shaped slots 22 opened on the rotating wheel 9. The anti-slip sleeve 20 can effectively increase the friction between the rotating wheel 9 and the inner wall of the precast well, thereby making the movement of the detection device in the precast well more stable. In addition, through the cooperation of the limiting strips 21 and the strip-shaped slots 22, the installation of the anti-slip sleeve 20 on the rotating wheel 9 can be limited, preventing the anti-slip sleeve 20 from rotating on the rotating wheel 9. The No. 1 motor 10 is fixedly installed on the inner top wall of the base 3. The No. 1 surface gear 11 is fixedly sleeved on the output shaft of the No. 1 motor 10. Several No. 1 linkage shafts 12 with equal rounded corners are rotatably inserted through bearings on the annular side wall of the base 3. One end of the No. 1 linkage shaft 12 is fixedly sleeved with a No. 1 spur gear 13 that meshes with the No. 1 surface gear 11. The second linkage shaft 14, there are several second linkage shafts 14, which are respectively rotatably inserted into several movable rods 5 through bearings. The other end of the first linkage shaft 12 is movably inserted into the second linkage shaft 14. The base 3 is provided with a synchronous adjustment mechanism 16 connected to the movable rods 5. The third linkage shaft 15, there are several third linkage shafts 15, which are rotatably installed in several movable frames 6 through bearings. The end of the third linkage shaft 15 is connected to the rotating rod 8 through a bevel gear pair. One end of the second linkage shaft 14 is connected to the third linkage shaft 15 through a bevel gear pair. The synchronization adjustment mechanism 16 includes: The second motor 16-1 is fixedly mounted on the inner bottom wall of the base 3. A second face gear 16-2 is fixedly sleeved on the output shaft of the second motor 16-1. Several threaded rods 16-3 with equal rounded corners are rotatably passed through the annular side wall of the base 3 via bearings. A second spur gear 16-4 that meshes with the second face gear 16-2 is fixedly sleeved at one end of the threaded rod 16-3. A partition 19 is fixedly installed inside the base 3. The output shafts of the first motor 10 and the second motor 16-1 are rotatably connected to the upper and lower side walls of the partition 19 via bearings. The partition 19 can provide support for the ends of the output shafts of the first motor 10 and the second motor 16-1, thereby effectively improving the rotational stability of the output shafts of the first motor 10 and the second motor 16-1. A fixed frame 16-5, comprising several fixed frames 16-5, is fixedly installed at the bottom of several fixed columns 4. The other end of the threaded rod 16-3 is rotatably connected to the fixed frame 16-5 via a bearing. A movable block 16-6 is rotatably fitted onto the threaded rod 16-3 via a threaded loop. The movable block 16-6 is movably installed in a movable groove 16-7 opened on the bottom wall of the fixed column 4, and is fixedly connected to the movable rod 5. Through a synchronous adjustment mechanism 16, the several movable rods 5 can be moved synchronously according to the diameter of the precast well, so that the several rotating wheels 9 can all abut against the inner wall of the precast well, realizing the adaptation of the detection device to precast wells of different diameters. Guide blocks 17 are fixedly installed on both sides of the movable block 16-6. The guide blocks 17 are movably installed in a guide groove 18 opened on the inner wall of the movable groove 16-7. The guide blocks 17 can provide auxiliary guidance for the movement of the movable block 16-6, thereby effectively improving the stability of the movable block 16-6.

[0018] When using this invention, the detection device is placed inside the precast well opening, and the second motor 16-1 is started. The second motor 16-1 drives the second face gear 16-2 to rotate, which in turn drives several second spur gears 16-4 to rotate synchronously. The second spur gears 16-4 drive the threaded rod 16-3 to rotate, causing the moving block 16-6 to move the movable rod 5. The movable rod 5 then drives the moving frame 6 to move, so that several rotating wheels 9 all come into contact with the inner wall of the precast well. Then, the first motor 10 can be started, which drives the first face gear 11 to rotate. The first face gear 11 drives several first spur gears 13 to rotate synchronously. The first spur gear 13 drives the first linkage shaft 12 to rotate. The first linkage shaft 12 drives the second linkage shaft 14 to rotate. The second linkage shaft 14 drives the third linkage shaft 15 to rotate through the bevel gear pair. The third linkage shaft 15 drives the rotating rod 8 to rotate through the bevel gear pair. The rotating rod 8 drives the rotating wheel 9 to rotate, realizing the movement of the detection device in the precast well. During this movement, the robotic arm 1 can also drive the detector 2 to move or rotate in multiple directions, so that the detector 2 can perform all-round detection of the inner wall of the precast well.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the coordinated action of the synchronous adjustment mechanism 16, the synchronous movement of multiple movable rods 5 can be controlled, so that several rotating wheels 9 can all abut against the inner wall of the precast well, realizing the rapid adaptation of the detection device in precast wells of different diameters, and significantly improving the versatility of the detection device. 2. The anti-slip sleeve 20 can not only increase the friction generated with the inner wall of the precast well and improve the stability of the detection device moving in the precast well, but also realize the convenient installation and removal of the anti-slip sleeve 20 on the rotating wheel 9 by using the plug-in cooperation of the limiting strip 21 and the strip groove 22. 3. The partition 19 can provide support for the output shaft ends of motor 10 and motor 16-1, thereby effectively improving the rotational stability of the output shafts of motor 10 and motor 16-1. 4. The guide block 17 can provide auxiliary guidance for the movement of the moving block 16-6, thereby effectively improving the stability of the moving block 16-6.
