While the installation work is relatively simple, it has a high clamping force, can perform clamping and stable work for a long time, and has a high service life.

[0017] 2. By providing the clamping spring and the damping spring, the track vibration generated after the train travels on the weighing track can be weakened, and the weighing track can always be directly above the dynamic weighing device. The air vibration generated by the train traveling affects the surrounding ground, and the slight vibration generated by the ground and the dynamic weighing device will be greatly reduced under the influence of the stable spring, so as to provide a relatively stable weighing environment for the dynamic weighing device and greatly improve the weighing accuracy during the dynamic weighing work of the dynamic weighing device.

[0018] 3.

[0037] The installation device of a high-speed multi-channel dynamic weighing system of the present invention has the following working process:

[0038] Before work, install the installation limit block 14 together with the dynamic weighing device 15 into the installation chassis 12, and move the installation chassis 12 to the lower end face of the weighing track 11, so that the middle concave part of the upper end face of the installation chassis 12 fits with the lower end face of the weighing track 11. At this time, place the top fixing frame 21 on the upper end face of the installation fixing block 20, and make the top fixing frame 21 fixed to the upper end face of the installation fixing block 20 by installing the installation screw 25. At this time, the clamping top plate 23 is initially in contact with the side end face of the weighing track 11. Then, by screwing and rotating the screw 28, drive the threaded moving plate 27 to move towards the side close to the weighing track 11, and under the extrusion of the clamping spring 22, make the clamping top plate 23 be able to fit and fix with the left and right end faces of the weighing track 11, and provide the clamping force through the resilience of the clamping spring 22. Then, screw the bottom screw 18. The rotation of the bottom screw 18 drives the clamping and moving frame 19 to move towards the side close to the weighing track 11, so that the clamping bottom block 24 clamps with the weighing track 11. After fitting, the clamping and moving frame 19 can be fixed to the installation fixing block 20 by installing the fixing screw 26, and the installation operation of the track weighing system can be completed. The clamping bottom block 24 and the clamping top plate 23 can clamp and fix the weighing track 11.

[0039] When the weight car or train travels above the weighing track 11, the provided clamping spring 22 and damping spring 38 can weaken the track vibration generated after the train travels on the weighing track 11, and keep the weighing track 11 directly above the dynamic weighing device 15 all the time. The air vibration generated by the train travel affects the surrounding ground, so that the slight vibration generated by the ground and the dynamic weighing device 15 will be greatly reduced under the influence of the stabilizing spring 36, thereby providing a relatively stable weighing environment for the dynamic weighing device 15 and greatly improving the weighing accuracy during the dynamic weighing operation of the dynamic weighing device 15. The information after weighing can be transmitted to the outside processor through the data transmission line 16.
