[0023] like Figures 1 to 6 As shown, a hydraulically driven foldable large-piece weighing system comprises: a weighing body 1, and two guide plates 2 respectively arranged at the front and rear ends of the weighing body 1;

[0024] The weighing body 1 comprises: a weighing bottom plate 11, and two rows of weighing plates 12 arranged on the weighing bottom plate 11, and the number of weighing plates 12 in each row is four; the weighing bottom plate 11 is 2m*5m; each weighing plate 12 is 1.20m*0.55m;

[0025] Each guide plate 2 is 1.2m*5m;

[0026] The two guide plates 2 and the weighing body 1 are connected by a hydraulic drive device. When transportation is required, the two guide plates 2 are folded above the weighing bottom plate 1 by the hydraulic drive device.

[0027] Two universal wheel seats 3 are provided on each side of the weighing body 1; a multi-section telescopic oil cylinder 41 is provided on the universal wheel seat 3, connected to a universal wheel 4, and the height of the universal wheel 4 is adjusted by the multi-section telescopic oil cylinder. After the large-scale weighing system is folded, the universal wheel 4 can be extended, and the weighing system can be pushed into the transport vehicle through the four universal wheels 4; when arriving at the weighing site, the weighing system is flattened and the four universal wheels 4 are retracted, so that the weighing system is laid flat on the ground.

[0028] The hydraulic drive device comprises: four hydraulic drive mechanisms 5 arranged on both sides,

[0029] Each hydraulic drive mechanism 5 includes: a hydraulic drive motor 52 and a three-link mechanism 53. The hydraulic drive motor 52 is arranged on the side of the weighing body 1 through a bracket 54 and is connected to the three-link mechanism 53. One end of the three-link mechanism 53 is connected to the side of the weighing body 1 through a rotating shaft 55, and the other end is connected to the side of the guide plate 2. The hydraulic drive motor 52 and the rotating shaft 55 are transmitted through a belt 56.

[0030] A handle 7 is also provided in the middle of the side of the weighing body 1 .

[0031] When the weighing system is arranged at the weighing site, a detachable support rotating body 6 is installed at the center below the bottom of the weighing body 1; the support rotating body 6 includes: a disc-shaped base 61, a cylindrical support member 63 for placing a thrust ball bearing 62 is provided in the center, and six universal ball bearings 64 are provided at intervals on the periphery. The support rotating body 6 can assist the four universal wheels 4 in rotating the weighing system in the direction. After the position of the weighing system is determined, the four universal wheels 4 are lowered by a multi-section telescopic cylinder, and the weighing body 1 is raised. At this time, the support rotating body 6 is separated from the weighing system, and then the support rotating body 6 is moved out of the weighing system by a tool, and the four universal wheels 4 are raised by a multi-section telescopic cylinder 41, so that they are retracted into the universal wheel seat 3, so that they are completely off the ground, and the guide plate 2 is unfolded by a hydraulic drive mechanism and laid flat on the ground, and then the weighing work can be carried out.

[0032] The present invention folds the weighing system for transportation, and when it arrives at the site, it only needs to be flattened, which can greatly save installation time, improve work efficiency, and ensure smooth roads.

[0033] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
