[0029] During operation, the track scale body 201 is installed on the road where the track is connected, and the motor 301 is started to rotate the active rod 302.

[0030] Furthermore, a through slot is fixedly provided at the top of the track scale body 201, and a weighing plate 202 is fixedly provided on the inner wall of the through slot. The weighing plate 202 enables the track scale body 201 to calculate corresponding data when a train passes through the rail 1. The bottom surfaces of the two rails 1 are fixedly provided with mounting posts 203. The inner wall of the track scale body 201 is fixedly provided with an electromagnet 204. The bottom surface of the mounting post 203 is magnetically connected to the top surface of the electromagnet 204. The magnetic attraction force of the electromagnet 204 on the mounting post 203 is much greater than the force of the longitudinal movement of the rail 1.

[0031] During operation, the mounting post 203 at one end of the rail 1 is inserted into the corresponding track scale body 201, and the electromagnet 204 is started, so that the electromagnet 204 magnetically attracts the mounting post 203 to fix it magnetically.

[0032] Furthermore, an active rod 302 is fixedly arranged on the left end face of the output rod of the motor 301, the model of the motor 301 is Y2-112M-6, and two bidirectional threaded rods 303 are respectively arranged on the inner walls of the front and rear ends of the track scale body 201, and the surfaces of the two bidirectional threaded rods 303 are respectively connected to the inner walls of the track scale body 201 by bearings for rotation;

[0033] During operation, the motor 301 is started to rotate the active rod 302 , and through the transmission effect of the three transmission wheels 304 and the belt 305 , the two bidirectional threaded rods 303 are rotated simultaneously.

[0034] Further, the left end surfaces of the active rod 302 and the two bidirectional threaded rods 303 are respectively fixedly sleeved with three transmission wheels 304, the three transmission wheels 304 have the same shape and size, the belts 305 are tightly wound around the surfaces of the three transmission wheels 304, the surfaces of the three transmission wheels 304 are wound with belts 305, the three transmission wheels 304 are connected by the belts 305, and the inner walls of the left and right ends of the track scale body 201 are fixedly provided with device blocks 306;

[0038] Furthermore, two springs 308 are fixedly arranged on the inner side surfaces of the front and rear ends of the connecting block 307, and a fixing plate 309 is fixedly arranged on the other end surfaces of the two springs 308. The inner wall of the bottom end of the fixing plate 309 is frictionally and slidably connected with the surface of the bidirectional threaded rod 303, and the inner side surfaces of the two fixing plates 309 at the left and right ends are respectively pressed and contacted with the outer side surfaces of the two rails 1;

[0039] During operation, when the connecting block 307 moves, the fixing plate 309 contacts the side of the rail 1. The fixing plate 309 is squeezed by the spring 308 to fix the side of the rail 1 and effectively reduce shock when the train passes through this section of the rail 1.

[0040] Working principle: When in use, first install the track scale body 201 on the track connection road, and insert the mounting column 203 at one end of the rail 1 into the track scale body 201, start the electromagnet 204, so that the electromagnet 204 magnetically attracts the mounting column 203 to fix it magnetically, start the motor 301, and rotate the active rod 302. Through the transmission action of the three transmission wheels 304 and the belt 305, the two bidirectional threaded rods 303 rotate at the same time, and through the action of the two reverse threads, the connecting block 307 moves in opposite directions. When the connecting block 307 moves, the fixing plate 309 contacts the side of the rail 1. Through the squeezing of the spring 308, the fixing plate 309 can fix the side of the rail 1 and effectively reduce the shock when the train passes through this section of the rail 1. When the electromagnet 204 magnetically attracts the mounting column 203, the rail 1 will not move longitudinally, and the weighing plate 202 inside the track scale body 201 can accurately analyze and calculate various data.
