Description

Technical Field

[0001] The utility model relates to the technical field of automobile scales, in particular to an electronic automobile scale with improved stability. Background Art

[0002] Weighbridges are also called truck scales. They are large scales set on the ground and are usually used to weigh the tonnage of a truck. They are the main weighing equipment used by factories, mines, and businesses for bulk cargo measurement. Weighbridges can be divided into I-beam weighbridges, T-beam weighbridges, L-beam steel weighbridges, U-beam weighbridges, channel steel weighbridges, and reinforced concrete weighbridges according to the scale structure; they can be divided into digital weighbridges and analog weighbridges according to the sensor type. The working principle of a truck weighbridge is that when the cargo enters the weighing platform, the elastic body of the weighing sensor undergoes elastic deformation under the action of the cargo's gravity, and the bridge impedance of the strain gauge attached to the elastic body loses balance, outputting an electrical signal proportional to the weight value. The digital signal is processed by the amplifier, A / D converter, microprocessor and other electronic components inside the sensor, and then enters the weighing display instrument through a repeater to directly display the weight and other data. If the display instrument is connected to a computer or printer, the instrument can simultaneously output the weight signal to the computer and other equipment to form a complete weighing management system.

[0003] Truck scales, also known as floor scales, are the main weighing equipment used for bulk cargo measurement in factories, mines, and businesses. In the mid-1980s, as high-precision weighing sensor technology became increasingly mature, mechanical floor scales were gradually replaced by electronic truck scales that are more accurate, more stable, and easier to operate.

[0004] A highly stable explosion-proof truck scale disclosed in the Chinese utility model patent application disclosure CN206339286U is provided with a fixing groove, and the tire of the vehicle to be weighed is sunk into the fixing groove for fixing, thereby preventing the parking position of the vehicle to be weighed on the truck scale from being unstable, resulting in uneven force on the weighing sensor and weighing errors. At the same time, an anti-skid layer is provided in the fixing groove. After the vehicle to be weighed is weighed, the anti-skid layer increases the friction with the vehicle to be weighed, making it easier for the vehicle to be weighed to drive out of the fixing groove, thereby greatly improving the practicality of the highly stable explosion-proof truck scale. However, during the use of the electronic truck scale, the center of gravity moves when the vehicle drives in, causing the weighing platform to shake, which will affect the subsequent vehicle driving in and out, as well as the stability of use and the accuracy of the weighing data, and is in urgent need of development. Utility Model Content

[0005] The purpose of the utility model is to provide an electronic truck scale with improved stability, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic truck scale with improved stability, comprising a supporting base, a hydraulic jack, a hydraulic buffer support and a weighing sensor, wherein the hydraulic jacks are symmetrically arranged at the bottom of the supporting base, the tops of the two hydraulic jacks are connected with connecting plates, the tops of the connecting plates are connected with connecting seats, the tops of the connecting seats are evenly connected with hydraulic buffer supports, the tops of the supporting bases are connected with an operating port, the bottom of the operating port is symmetrically connected with weighing sensors, a weighing platform is arranged at the top of the operating port, the bottom of the weighing platform is connected with an explosion-proof layer, the bottom surface of the explosion-proof layer is contacted with the bottom of the hydraulic buffer support, the two ends of the bottom of the explosion-proof layer are symmetrically connected with pillars, and the bottoms of the pillars are connected with positioning blocks.

[0007] Preferably, driving slopes are symmetrically connected to both sides of the supporting pier, and speed bumps are laid on the top surfaces of the driving slopes.

[0008] Preferably, two sides of the operating port are symmetrically connected with limiting sliding grooves.

[0009] Preferably, two groups of limiting wheel grooves are symmetrically connected inside the top of the weighing platform, and the inner surfaces of the limiting wheel grooves are paved with an anti-slip layer.

[0010] Preferably, guide wheels are symmetrically connected to both sides of the weighing platform.

[0011] Preferably, the bottom of the positioning block corresponds to the position setting of the weighing sensor.

[0012] Preferably, the guide wheel is slidably connected to the limiting slide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) This electronic vehicle scale with improved stability uses a hydraulic jack to separate the weighing platform and the weighing sensor, and uses a hydraulic buffer support to achieve a buffering force when a vehicle just enters, so that the weighing platform and the positioning block connected to the bottom can smoothly contact the weighing sensor, and when the hydraulic buffer support is lowered, the weighing can be carried out smoothly, and the device can buffer the impact force generated by the weighing platform when the vehicle just enters, thereby enhancing the load-bearing capacity of the device;

[0015] (2) This type of electronic truck scale with improved stability realizes the up and down movement of the limited stability auxiliary weighing platform through the coordinated use of the guide wheel and the limit slide, improves the stability of the weighing platform and the support, and effectively improves the service life of the weighing platform, positioning block, and weighing sensor component structure;

[0016] (3) This electronic truck scale with improved stability can effectively prevent the parking position of the vehicle to be weighed from being unstable on the weighing platform, which would cause uneven force on the weighing sensor and thus weighing errors, by setting a limit wheel groove and an anti-skid layer. The anti-skid layer can increase the friction with the vehicle to be weighed, thereby improving the practicality of the truck scale. The explosion-proof layer is made of tempered glass, so that its surface has compressive stress. When it is subjected to external force, the surface stress is first offset, thereby improving the overall bearing capacity of the weighing platform and enhancing the glass's own resistance to wind pressure, cold and heat, and impact, thereby ensuring explosion-proof safety and practicality.
