Description

Technical Field

[0001] The utility model relates to the technical field of truck scales, in particular to an electric rail truck scale. Background Art

[0002] A truck scale, also known as a floor scale, is a large scale installed on the ground. It is usually used to weigh the tonnage of cargo carried by vehicles such as trucks and vans. It is also the main weighing equipment used for measuring bulk goods in factories, mines, and businesses.

[0003] When an electric rail truck scale is in operation, cargo enters the weighing platform. Under the action of the cargo's weight, the elastic body of the weighing sensor undergoes elastic deformation, causing the bridge impedance of the strain gauge attached to the elastic body to lose balance, and outputting an electrical signal proportional to the weight value. After being processed by the sensor's internal amplifier, A / D converter, microprocessor and other electronic components, the output digital signal is then transmitted through a repeater to the weighing display instrument, which directly displays the weight and other data. If the display instrument is connected to a computer or printer, the instrument can also output the weight signal to the computer and other devices, forming a complete weighing management system.

[0004] However, the electric rail truck scale in the prior art has the following defects when in use: 1. It cannot be lifted conveniently and effectively, so that it cannot move the lifting blocking plate out or in conveniently, and furthermore, it cannot effectively block the front wheel from collision, which reduces its blocking and collision prevention efficiency, and it cannot effectively adjust the position of the lifting blocking plate, which makes it unable to adapt to the use of different vehicles, reducing its use efficiency and work efficiency; 2. When the existing truck scale is in use, when the vehicle is loaded and weighed, after the vehicle drives onto the truck scale, it needs to be informed by an outsider to know that the vehicle has arrived at the designated position. This method is more troublesome and requires too much labor, and is not suitable for popularization and use; 3. It cannot effectively limit the position, and it cannot effectively adjust the limit position, which reduces its limit efficiency and use efficiency. Therefore, we proposed an electric rail truck scale. Summary of the Invention
