[0002] With the rapid development of electronic technology in the new century, the price of electronic scales and balances has dropped significantly. Modern high-precision electronic balances can distinguish down to the microgram level and have improved environmental adaptability. As is well known, when unloading and weighing goods loaded on large trucks, the goods are usually first unloaded from the truck, then transported to a weighing scale or electronic scale for weighing, and finally moved to the designated location.

[0003] According to the patent titled "An Electronic Weighing Device with Hydraulic Lifting Function" (Patent Publication No.: CN211651811U, Patent Publication Date: 2020-10-09), the device includes a base. The upper surface of the base has two ends fixedly connected to the bottom ends of a lifting plate via hydraulic telescopic rods. A support plate is mounted on the lifting plate via shock absorbers, and a pressure sensor is fixedly installed at the connection between the bottom of the support plate and the shock absorbers. A display is installed at one end of the lifting plate. A weighing platform is fixedly mounted on the upper surface of the support plate. The weighing platform and support plate are easily disassembled and assembled, facilitating cleaning of the weighing platform. The height of the weighing platform is easily adjustable, allowing workers to directly move goods onto the platform for weighing, saving time and effort and improving the practicality of the weighing device.

[0004] Based on the aforementioned existing technologies, current electronic weighing equipment with hydraulic lifting functions still has the following problems: once installed, traditional equipment permanently occupies a specific location and cannot be flexibly adjusted according to production needs or logistics changes. In scenarios with limited space or requiring weighing at multiple locations, multiple devices must be purchased or inefficient handling tools must be relied upon. Therefore, this utility model provides an electronic weighing device with hydraulic lifting function. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An electronic weighing device with hydraulic lifting function includes a lifting weighing mechanism 1. A moving mechanism 2 is provided below the lifting weighing mechanism 1 to facilitate movement of the lifting weighing mechanism 1. The moving mechanism 2 includes:

[0025] The walking unit 21 is located below the lifting and weighing mechanism 1 and includes a mounting base box 211. Four sets of limiting rails 212 are fixedly installed inside the mounting base box 211. A set of lifting plates 213 is slidably installed inside the limiting rails 212. A base plate 214 is fixedly installed at the bottom of the lifting plate 213, and straight wheels 215 and omnidirectional wheels 216 are fixedly installed at the bottom of the base plate 214. The lifting plate 213 moves up and down to make the straight wheels 215 and omnidirectional wheels 216 contact or not contact the ground, thereby realizing the movement of the lifting and weighing mechanism 1.

[0026] The fixed unit 22 is located inside the walking unit 21 and is used to drive the movement of the lifting plate 213.

[0027] In this embodiment, the walking unit 21 also includes four mounting seats 218 fixedly installed at the four corners of the mounting base box 211. The mounting seat 218 has a threaded rotating rod 219 rotatably installed inside, and a support plate 2110 is rotatably installed at the bottom end of the threaded rotating rod 219. By rotating the threaded rotating rod 219, the support plate 2110 is brought into contact with the ground to support and fix the device. A set of rectangular grooves 2111 is opened at the bottom of the mounting base box 211, and the bottom plate 214 is adapted to enter the rectangular grooves 2111.

[0028] The equipment is stably supported on uneven ground by using four independently adjustable threaded rotating rods 219 and support plates 2110.

[0029] The rectangular groove 2111 design ensures that the lifting plate 213 fits seamlessly with the base box when it is raised or lowered, avoiding structural interference.

[0030] In this embodiment, the fixing unit 22 includes a small hydraulic rod 221 fixedly installed inside the mounting base box 211. A movable seat 222 is fixedly installed at one end of the small hydraulic rod 221, and a set of connecting rods 223 are fixedly installed on both sides of the movable seat 222. A roller 224 is rotatably installed at one end of the connecting rod 223.

[0031] The small hydraulic rod 221, model YHG1, horizontally pushes the roller 224 along the inclined groove 217, converting the horizontal thrust into vertical lifting. It has a compact mechanical structure and hydraulic drive to provide high output force, ensuring the smooth lifting of heavy equipment.

[0032] In this embodiment, a set of inclined grooves 217 are provided inside the lifting plate 213, and the roller 224 slides inside the inclined grooves 217. The lifting plate 213 moves up and down by sliding the base plate 214.

[0033] In this embodiment, the lifting and weighing mechanism 1 includes a base 11 fixedly installed on the top of the mounting box 211. A set of first cross rods 12 are rotatably installed inside the base 11. A set of second cross rods 13 are rotatably installed on the inner side of the first cross rods 12. A top seat 16 is rotatably installed on the upper end of the second cross rods 13. The first cross rods 12 are movably installed on the left side of the base 11. One end of the lifting hydraulic rod 112 is connected to its movable component through a connecting seat on the inner side of the second cross rods 13. A second pulley 18 is rotatably installed on the upper end of the first cross rods 12. An upper limit seat 17 is fixedly installed below the top seat 16. The second pulley 18 slides inside the groove of the upper limit seat 17. A first pulley 14 is rotatably installed on the lower end of the second cross rods 13. A set of lower limit seats 15 is fixedly installed inside the base 11. The first pulley 14 slides inside the groove of the lower limit seat 15. The lifting hydraulic rod 112 pushes the second cross rods 13 to achieve the cross rotation of the first cross rods 12 and the second cross rods 13, thereby realizing the lifting and lowering of the device. The controller 111 is fixedly installed on the top right side of the mounting box 211.

[0034] The lifting hydraulic rod 112 is model YB1-4. When the lifting hydraulic rod 112 operates, it pushes the connecting seat inside the second cross rod 13, causing the first cross rod 12 and the second cross rod 13 to rotate crosswise. At the same time, the first pulley 14 slides inside the groove of the lower limit seat 15, and the second pulley 18 slides inside the groove of the upper limit seat 17, causing the top seat 16 to rise. The top seat 16 drives the weighing platform 19 to rise synchronously to a suitable weighing height for weighing.

[0035] In this embodiment, a weighing platform 19 is fixedly installed on the top of the top seat 16, and three sets of baffles 110 are fixedly installed on all four sides of the weighing platform 19.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, firstly, the small hydraulic rod 221 is operated to push the movable seat 222 to move. The movable seat 222 slides the roller 224 inside the inclined groove 217 through the connecting rod 223, causing the lifting plate 213 to move down. The lifting plate 213 drives the straight wheel 215 and the universal wheel 216 to move down synchronously through the base plate 214, so that the straight wheel 215 and the universal wheel 216 contact the ground to support the device and move the device.

[0038] Next, the operator rotates the threaded rod 219, which drives the support plate 2110 to move down, so that the support plate 2110 contacts the ground to support the device and fix the position of the device.

[0039] Then, the lifting hydraulic rod 112 operates to push the connecting seat inside the second cross rod 13, causing the first cross rod 12 and the second cross rod 13 to rotate crosswise. At the same time, the first pulley 14 slides inside the groove of the lower limit seat 15, and the second pulley 18 slides inside the groove of the upper limit seat 17, causing the top seat 16 to rise. The top seat 16 drives the weighing platform 19 to rise synchronously to a suitable weighing height for weighing.
