The two ends of the connecting spring are fixedly connected to the surface of the upper plate and the surface of the lower plate, respectively. A key and a groove are respectively provided at the corresponding positions of the end of the detection wheel 434 that penetrates into the guide tube 431 and the inner wall of the guide tube 431.

[0039] In this embodiment, the structure and connection relationship of the tilt measuring device 43 are further explained. The tilt measuring device 43 is set up to facilitate the detection of whether the horizontal values ​​at both ends of the top of the stone 1 are within the qualified range. When in use, the detection wheel 434 rises and falls synchronously with the stone 1. During the rising and falling process, the detection wheel 434 squeezes the elastic mechanism 433 synchronously. When the elastic mechanism 433 is compressed, the pressure value detected by the pressure sensor 432 will change. When the pressure values ​​detected by the two sets of pressure sensors 432 differ from the set range, it means that the horizontal values ​​at both ends of the top of the stone 1 are not within the qualified range.

[0040] As a preferred embodiment of this example, Figures 1-7As shown, the front guide device 44 includes a front transverse shaft 441, a double-acting lead screw 442, a front drive bevel gear 443, a carriage 444, a plane detection assembly 445, a front wheel 446, and a front drive bevel gear 447. The front transverse shaft 441 is rotatably connected to the bottom of the frame 41. The double-acting lead screw 442 is rotatably connected to the bottom of the frame 41 and located on one side of the top of the front transverse shaft 441. The front drive bevel gear 443 is fixedly connected to the center of the outer surface of the double-acting lead screw 442. The carriage 444 is symmetrically threaded to the outer surface of the double-acting lead screw 442 and slidably connected to the outer surface of the front transverse shaft 441. The two sets of carriages 444 are along the outer surface of the double-acting lead screw 442. The outer surfaces of the front transverse shaft 441 move inward or outward synchronously. The plane detection component 445 is symmetrically installed on the surface of the carriage 444. The plane detection component 445 is electrically connected to the controller 47. Both ends of the front transverse shaft 441 extend out of the frame 41 and are fixedly connected to the front wheel 446. The front wheel 446 corresponds to the position of the curb stone 2. The front drive bevel gear 447 is rotatably connected to the bottom of the frame 41 and is located on one side of the top of the front transmission bevel gear 443. The front drive bevel gear 447 is meshed with the front transmission bevel gear 443. One end of the central shaft of the front drive bevel gear 447 extends out of the top of the frame 41 and is connected to one end of the adjusting handle 49.

[0041] In this embodiment, the structure and connection relationship of the front guide device 44 are further explained. The front guide device 44 is set up to facilitate guidance and can also detect the flatness of the sides of two adjacent groups of stones 1. In use, the front drive bevel gear 447 rotates synchronously to drive the front transmission bevel gear 443 to rotate. The rotation of the front transmission bevel gear 443 drives the bidirectional lead screw 442 to rotate synchronously. The rotation of the bidirectional lead screw 442 drives the two sets of slides 444 to move synchronously inward or outward to realize distance adjustment. The movement of the slides 444 drives the plane detection component 445 to move synchronously. During the movement, the plane detection component 445 contacts the sides of the two groups of stones 1 one after the other. When the pressure values ​​detected by the pressure sensors 432 in the two sets of plane detection components 445 differ from the set range, it means that the sides of the two adjacent groups of stones 1 are not on the same plane.

[0042] As a preferred embodiment of this example, Figures 1-7 As shown, the planar detection component 445 has the same structure as the tilt measuring device 43.

A pointer 492 is sleeved on the outside of the adjusting handle 49, and one end of the pointer 492 corresponds to the position of the scale line. One end of the adjusting handle 49 passes through the bottom of the mounting box 45 and is connected to one end of the central shaft of the front drive bevel gear 447 that passes through the top of the frame 41.

[0049] In this embodiment, the scale lines and pointer 492 are set to facilitate timely knowledge of the displacement information of the carriage 444, resulting in good performance.

Both the drive motor 4102 and the encoder 4103 are electrically connected to the controller 47.

[0051] In this embodiment, the structure and connection relationship of the electric drive device 410 are further explained. The electric drive device 410 is set up to facilitate the operation of the rear drive device 42 and has a good working effect.

[0052] As a preferred embodiment of this example, Figures 1-7 As shown, marking devices 411 are symmetrically installed on the top of the frame 41 and the surface of the carriage 444. The marking devices 411 are located inside the tilt measuring device 43 and the plane detection component 445, respectively. The marking device 411 consists of an electric spraying mechanism and a material box. The controller 47 is electrically connected to the electric spraying mechanism. The controller 47 controls the operation of the electric spraying mechanism. The electric spraying mechanism extracts the liquid inside the material box and sprays it onto the surface of the stone 1 to form a mark.

[0053] In this embodiment, the structure and connection relationship of the marking device 411 are further explained. The marking device 411 is set up to mark the stones 1 that need to be adjusted, which facilitates subsequent unified adjustment and has a good effect.

[0054] Working principle of this invention: In use, first turn the adjusting handle 49. The rotation of the adjusting handle 49 synchronously drives the front drive bevel gear 447 to rotate. The rotation of the front drive bevel gear 447 synchronously drives the front transmission bevel gear 443 to rotate. The rotation of the front transmission bevel gear 443 synchronously drives the double-acting screw 442 to rotate. The rotation of the double-acting screw 442 synchronously drives the two sets of slides 444 to move inward synchronously, realizing distance adjustment. The movement of the slides 444 synchronously drives the plane detection component 445 to move until one end of the plane detection component 445 contacts the side of the stone 1. The system then controls the drive motor 4102 to rotate via the controller 47. The drive motor 4102, after being reduced in speed by the reducer 4101, synchronously drives the rear transmission bevel gear 422 to rotate. The rear transmission bevel gear 422 then synchronously drives the rear drive bevel gear 424 to rotate. The rear drive bevel gear 424 then synchronously drives the rear transverse shaft 423 to rotate. The rear transverse shaft 423 then synchronously drives the rear wheel 425 to rotate, thus moving the entire frame 41. The system performs well, and the plane detection component 445 interacts with two adjacent groups during the movement. When the sides of the stones 1 are in contact, if the pressure values ​​detected by the pressure sensors 432 in the two sets of plane detection components 445 differ from the set range, it indicates that the sides of the two adjacent sets of stones 1 are not on the same plane. At this time, the controller 47 controls the audible and visual alarm to issue an alarm message, and simultaneously controls the marking device 411 to operate and mark the sides of the stones 1. The detection wheel 434 in the tilt measuring device 43 moves up and down synchronously with the undulation of the stones 1 during the movement. During the rising and falling process, the detection wheel 434 simultaneously squeezes the elastic mechanism 433. When the elastic mechanism 433 is compressed, it causes the pressure value detected by the pressure sensor 432 to change. When the pressure values ​​detected by the two sets of pressure sensors 432 differ from the set range, it indicates that the horizontal values ​​at both ends of the top of the stones 1 are not within the qualified range. At this time, the controller 47 controls the audible and visual alarm to issue an alarm message, and simultaneously controls the marking device 411 to operate and mark the top of the stones 1. The number of marks can be directly read through the display screen on the controller 47, which makes it easy to know in time the number of stones 1 that need to be adjusted, and the effect is good.
