The measuring component is arranged on the top plate 103 for cooperating with the driven component for use.

[0021] Specifically, it should be noted here that the sensor 410 is electrically connected to the control unit through a wire. When the trigger block 409 touches the sensor 410, it counts once, and then calculates through the number of times and the distance required for the number of rotations of the driven rod 401, so as to facilitate measuring the moving distance of the frame 1. The specific working principle between them is all cited through the prior art and will not be elaborated here.

[0022] As an implementation manner in this embodiment, the driven component includes a carrier plate 2 fixedly installed on the top plate 103. One side of the carrier plate 2 is fixedly connected with a pair of slide rails 201. A slider 202 is slidably connected to the pair of slide rails 201.

A first spring 222 is sleeved on the positioning rod 220. Both ends of the first spring 222 are fixedly connected to the top surface of the sleeve 219 and the bottom surface of the collar 221 respectively.

[0023] Specifically, when the frame 1 is moving, wheels 102 are provided at the bottom position of the frame 1. When the wheels 102 are moving, a docking plate 207 is provided on the bottom surface of the frame 1, and hinge seats 208 are fixedly connected to the bottom surface position of the docking plate 207. A rod body 209 is rotatably connected to the hinge seats 208, and a roller 210 is fixedly connected to the rod body 209. The roller 210 on the rod body 209 rolls by being in contact with the ground during the movement of the frame 1. When the roller 210 encounters an uneven road surface, the docking plate 207 moves upward. The movement of the docking plate 207 causes the slider 202 to slide on the slide rail 201. The movement of the slider 202 causes the rotating sleeve 204 on the side rod 203 to slide inside the chute 215. Then, the roller 210 always rolls by being in contact with the ground due to the elastic force of the first spring 222.

[0024] As an implementation manner in this embodiment, the limiting component includes a pair of first shaft seats 3 fixedly installed at the bottom surface position of the load-carrying plate 2. A slide bar 301 is fixedly connected to the pair of first shaft seats 3. A sleeve block 302 is slidably connected to the slide bar 301. A snap ring 303 is fixedly connected to one end of the slide bar 301. A second spring 304 is sleeved on the slide bar 301. Two ends of the second spring 304 are respectively fixedly connected to one side of the sleeve block 302 and one side of the snap ring 303. A docking seat 305 is fixedly connected to the top surface position of the sleeve block 302. A pair of pulleys 306 are rotatably connected to the docking seat 305. The pair of pulleys 306 are slidably connected to a storage plate 307. One end of the storage plate 307 is fixedly connected to the first shaft seat 3. One side of the sleeve block 302 is fixedly connected to a main shaft 308. One end of the main shaft 308 is rotatably connected to a second belt pulley 309. A transmission belt 310 is sleeved on the second belt pulley 309. The bottom end of the transmission belt 310 is sleeved on a first belt pulley 211.

[0025] Specifically, when it is necessary to rotate the third belt pulley 402 on the driven rod 401, when the roller 210 rolls on the ground, the first belt pulley 211 on the rod body 209 is driven to rotate. The transmission belt 310 is sleeved on the first belt pulley 211. The rotation of the first belt pulley 211 drives the transmission belt 310 to rotate. The transmission belt 310 is sleeved on the second belt pulley 309. When the roller 210 encounters an uneven road surface, the sleeve block 302 slides on the slide bar 301 due to the elastic force of the second spring 304, avoiding the phenomenon of the transmission belt 310 coming off. The other end of the transmission belt 310 is sleeved on the third belt pulley 402. The rotation of the transmission belt 310 drives the driven rod 401 on the third belt pulley 402 to rotate.

[0026] As an implementation manner in this embodiment, the measuring component includes a pair of second shaft seats 4 fixedly installed on the load-carrying plate 2. A driven rod 401 is rotatably connected to the pair of second shaft seats 4. Third belt pulleys 402 are fixedly connected to both ends of the driven rod 401. The transmission belt 310 is sleeved on the third belt pulley 402. A cam 403 is fixedly connected to the middle position of the driven rod 401. A pair of insertion rods 404 are fixedly connected to the load-carrying plate 2. A limiting plate 405 is fixedly connected to the top ends of the pair of insertion rods 404. A sleeve seat 406 is slidably connected to the insertion rods 404. The sleeve seat 406 is fixedly connected to a movable block 407. The cam 403 is attached to the bottom surface position of the movable block 407. A third spring 408 is sleeved on the pair of insertion rods 404. A trigger block 409 is fixedly connected to the top surface position of the movable block 407. A sensor 410 is arranged at the top position of the trigger block 409. The sensor 410 is fixedly installed at the bottom surface position of the limiting plate 405.

[0027] Specifically, a cam 403 is fixedly connected to the middle position of the follower rod 401. The rotation of the follower rod 401 drives the cam 403 to rotate. The movable block 407 is attached to the cam 403 by the elastic force of the third spring 408. The rotation of the cam 403 drives the movable block 407 to move. Both ends of the movable block 407 are fixedly connected with socket seats 406, and the socket seats 406 are slidably connected to the plug rods 404. The movement of the movable block 407 slides on the plug rods 404 through the socket seats 406. When the cam 403 rotates one circle, the trigger block 409 on the movable block 407 contacts the sensor 410, so as to facilitate the measurement of the moving distance of the frame 1.

[0028] Working principle of the present invention: When the frame 1 is moving, wheels 102 are provided at the bottom of the frame 1. When the wheels 102 are moving, a docking plate 207 is provided on the bottom surface of the frame 1, and a hinge seat 208 is fixedly connected to the bottom surface of the docking plate 207. A rod body 209 is rotatably connected to the hinge seat 208, and a roller 210 is fixedly connected to the rod body 209. The movement of the frame 1 causes the roller 210 on the rod body 209 to roll on the ground. When the roller 210 encounters an uneven road surface, the docking plate 207 moves upward. The movement of the docking plate 207 causes the slider 202 to slide on the slide rail 201. The movement of the slider 202 causes the rotating sleeve 204 on the side rod 203 to slide inside the chute 215, and then the elastic force of the first spring 222 makes the roller 210 always roll on the ground; When it is necessary to rotate the third pulley 402 on the follower rod 401, when the roller 210 rolls on the ground, it drives the first pulley 211 on the rod body 209 to rotate. A transmission belt 310 is sleeved on the first pulley 211. The rotation of the first pulley 211 drives the transmission belt 310 to rotate. The transmission belt 310 is sleeved on the second pulley 309. When the roller 210 encounters an uneven road surface, the elastic force of the second spring 304 makes the sleeve block 302 slide on the slide rod 301 to prevent the transmission belt 310 from becoming disengaged. The other end of the transmission belt 310 is sleeved on the third pulley 402, and the rotation of the transmission belt 310 drives the follower rod 401 on the third pulley 402 to rotate; A cam 403 is fixedly connected to the middle position of the follower rod 401. The rotation of the follower rod 401 drives the cam 403 to rotate. The movable block 407 is attached to the cam 403 by the elastic force of the third spring 408. The rotation of the cam 403 drives the movable block 407 to move. Both ends of the movable block 407 are fixedly connected with socket seats 406, and the socket seats 406 are slidably connected to the plug rods 404. The movement of the movable block 407 slides through the socket seats 406 on the plug rods 404. When the cam 403 rotates one circle, the trigger block 409 on the movable block 407 contacts the sensor 410, so as to facilitate the measurement of the moving distance of the frame 1.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
