[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 includes: a weighing base plate 11, and two rows of weighing plates 12 arranged on the weighing base plate 11, with each row of weighing plates 12 having four pieces; the weighing base 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 base plate 1 by the hydraulic drive device.

[0027] Each side of the weighing body 1 is equipped with two universal wheel mounts 3. Each universal wheel mount 3 is equipped with a multi-section telescopic cylinder 41, which connects to a universal wheel 4. The height of the universal wheel 4 is adjusted by the multi-section telescopic cylinder. After the large-scale weighing system is folded, the universal wheels 4 can be extended, and the weighing system can be pushed into the transport vehicle via the four universal wheels 4. At the weighing site, the weighing system is flattened and the four universal wheels 4 are retracted, allowing the weighing system to be 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 deployed at the weighing site, a removable support rotator 6 is installed at the center below the bottom of the weighing body 1. The support rotator 6 comprises a disc-shaped base 61, a cylindrical support member 63 at its center housing a thrust ball bearing 62, and six universal ball bearings 64 spaced apart on the periphery. The support rotator 6 assists the four universal wheels 4 in rotating the weighing system. After the weighing system is positioned, the four universal wheels 4 are lowered via a multi-section telescopic cylinder, and the weighing body 1 is raised. The support rotator 6 is then removed from the weighing system using tools. The four universal wheels 4 are then raised via a multi-section telescopic cylinder 41, retracted into the universal wheel seat 3, and completely lifted off the ground. The guide plate 2 is then unfolded and laid flat on the ground by a hydraulic drive mechanism, and weighing can then begin.

[0032] The utility model can fold 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 traffic.

[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.
