Two symmetrically distributed first fixing seats 21 are fixedly installed on the upper surface of the inner wall of the groove 2, and a first threaded rod 22 with the same thread is rotatably installed on the top of each first fixing seat 21. The outer sides of the two first threaded rods 22 are threadedly connected with a moving block 23, and the moving block 23 is slidably clamped in the first empty groove 2. The opposite ends of the moving block 23 are fixedly installed with a limiting column 24. A slot 25 corresponding to the limiting column 24 is opened through the middle of the U-shaped fixing block 16. The positioning device 17 mainly includes: GPS positioning, incremental encoder ranging positioning, laser ranging positioning, RFID positioning, infrared positioning, ultrasonic positioning, contact sensor positioning, etc.

[0021] The first and second screw rods 22 are connected to the drive shaft 31 and the second screw rods 22 are connected to the drive shaft 31. The first and second screw rods 22 are connected to the drive shaft 31 and the second screw rods 22 are connected to the drive shaft 31.

[0022] A second slot 5 is provided at the bottom of the support plate 14, and two symmetrically distributed second fixing seats 50 are fixedly installed on the lower surface of the inner wall of the second slot 5. A worm 51 is rotatably installed at the bottom of the second fixing seat 50, and a worm wheel 52 is meshingly connected to the outer side of the worm 51. A rotating rod 53 is fixedly passed through the middle of the worm wheel 52, and the bottom end of the rotating rod 53 is fixed on the connecting block 15, and the top end of the rotating rod 53 is rotatably clamped in the support plate 14, and the worm 51 rotates and passes through the support plate 14.

[0023] A plurality of evenly distributed annular limit blocks 4 are fixedly mounted on the outside of each limit column 24. A limit groove 41 corresponding to the limit block 4 is provided through the middle of the U-shaped fixed block 16 and located on the outside of the card slot 25. By providing the limit block 4 and the limit groove 41, the limit column 24 is more stable when it is inserted into the card slot 25.

[0024] The bottom ends of the two connecting plates 13 are penetrated by two symmetrically distributed third slots 6, and the bottom end of the slide seat 11 is threadedly connected with a second threaded rod 61 corresponding to the third slots 6. The second threaded rod 61 penetrates the corresponding third slots 6, and the bottom end of each second threaded rod 61 is fixedly installed with a fixing plate 62, and the bottom end of the fixing plate 62 is fixedly installed with a diamond block 63. By setting the second threaded rod 61, when the diamond block 63 is rotated, the fixing plate 62 is driven to rotate, thereby driving the second threaded rod 61 to rotate. The second threaded rod 61 is threadedly connected to the slide seat 11, so that the fixing plate 62 slowly fits with the slide seat 11. When the fixing plate 62 fits on the slide seat 11, the fixing plate 62 and the third slot 6 are in a cross shape, thereby fixing the connecting plate 13 and the support plate 14 on the slide seat 11. The operation is simple, easy to disassemble and install, and can be installed and disassembled without the aid of other tools.

[0025] The length and width of each third slot 6 are longer than those of the fixing plate 62 , so that the third slot 6 in the connecting plate 13 can quickly pass through the fixing plate 62 , and the connecting plate 13 and the supporting plate 14 can be disassembled more quickly.

[0026] A motor 54 is fixedly installed on one side of the support plate 14 away from the inspection robot 12 . The driving end of the motor 54 is fixedly installed on the end of the worm 51 . By setting the motor 54 , when the motor 54 is started, the worm 51 is driven to rotate, thereby driving the worm wheel 52 to rotate.

[0027] Working principle: In actual use, when the positioning device 17 needs to be installed on the connecting block 15, first rotate the rotating shaft 3 to drive the main bevel gear 31 to rotate, thereby driving the two slave bevel gears 32 to rotate. The cooperation between the main bevel gear 31 and the slave bevel gear 32 drives the corresponding first threaded rod 22 to rotate at the same time. With the rotation of the first threaded rod 22, the corresponding moving block 23 and the limiting column 24 are driven to move in the opposite direction in the first slot 2, so that the limiting column 24 is stuck in the corresponding slot 25 in the U-shaped fixing block 16, so that the positioning device 17 is installed on the connecting block 15 through the U-shaped fixing block 16;

[0028] When the positioning device 17 needs to be rotated, the worm 51 is rotated to drive the worm wheel 52 to rotate. The worm 51 and the worm wheel 52 cooperate to drive the connecting block 15 to rotate, thereby driving the positioning device 17 installed on the connecting block 15 to rotate.
