Problems solved by technology

However, due to its mobility, it is limited by the physical conditions of the ground. The flatness of the ground has a considerable impact on the placement of the scale and the accuracy of the display, which greatly limits the scope of use of the portable truck scale and causes measurement problems. Increase in cost and decrease in precision and accuracy

Abstract

The invention provides a self-levelling portable truck scale, and particularly relates to a portable truck scale with a self-levelling function. The scale includes approach ramps, balancing boards, pressure sensors, hydraulic levelling devices, a control box, a computer and a printer, wherein the quantity of the approach ramps and the quantity of the balancing boards are even numbers, the approach ramps are arranged on the two ends of each balancing board, and the two balancing boards are parallel to each other; the balancing boards and the approach ramps are all connected through connecting rods, and the four corners of the lower end of each balancing board are provided with the pressure sensors and the hydraulic levelling devices. The pressure sensors and the printer are connected with the computer, and when the hydraulic levelling devices are connected with the control box for usage, the flatness can be adjusted according to actual conditions.

Description

technical field [0001] The invention relates to a truck scale, in particular to a portable truck scale with self-levelling function. Background technique [0002] Truck scales, commonly known as "weighbridges", are large scales set on the ground. They are usually used to weigh the tonnage of trucks. They are the main weighing equipment used for bulk cargo measurement in factories, mines, and businesses. Traditional truck scales are mainly mechanical and electrical, require foundation pits, and can only be used for static weighing. In recent years, with the development of technology, truck scales have developed in the direction of modularization and intelligence. They do not need foundation pits, can be used in the open air, are easy to install, have low infrastructure costs, and are portable vehicles with digital display, intuitive, fast speed, and high precision. Balance. However, due to its mobility, it is limited by the physical conditions of the ground. The flatness of...
