Truck scale pre-arching device and technology

Abstract

The invention relates to the field of metering and weighing, and in particular relates to a truck scale pre-arching device and technology. The pre-arching device comprises a portal, a hydraulic arm and a force applying fixture, wherein the hydraulic arm is vertically fixed to the lower side of the portal and points to the ground, the force applying fixture is connected to the lower end of the hydraulic arm and installed to be longitudinally symmetrical to structural steel on the truck scale. The force applying fixture comprises a fixture body and a force applying plate, wherein the upper end of the fixture body is connected to the hydraulic arm, the force applying plate is arranged at the lower end of the fixture body and horizontally stretches towards the two sides of the fixture body to form a horizontal plate for applying force to the structural steel. The lower part of the fixture body is provided with an opening, and the shape of the opening is matched with the top structure of the structural steel; the force applying plate is arranged at the bottom of the fixture body and also arranged on the place which is directly contacted with the structural steel to apply force. According to the truck scale pre-arching device and technology, the surface of a weighing platform can be slightly protruded, thus overcoming the ponding problem of the weighing platform, increasing intensity of the weighing platform, and ensuring that the truck scale can be effectively and safely used for a longer time.

Description

technical field [0001] The invention relates to the field of metering and weighing, in particular to equipment and a process for pre-processing a metering device, and more particularly, to a device and a process for pre-arching a truck scale. Background technique [0002] Truck scales, also known as weighbridges, are the main weighing equipment used for bulk cargo measurement in factories, mines, and merchants. Truck scales that were common before the 1980s were also called mechanical weighbridges. In the mid-1980s, with the maturity of high-precision weighing sensor technology, mechanical weighbridges were gradually replaced by electronic truck scales with high precision, good stability, and easy operation. Roads, factories and mines and other fields. [0003] However, in the production process of truck scales, due to the large area of ​​the weighing platform and the dense distribution of weighing beams, the weighing beams of each part, that is, the section steel connecte...

Problems solved by technology

[0003] However, in the production process of the truck scale, due to the large area of ​​the weighing platform and the dense distribution of the weighing beams, the weighing beams of each part, that is, the section steel connected to the weighing platform panel, is often deformed due to welding due to heat, and every The deformation of a section of section steel is also inconsistent, so the surface of the weighing platform is often uneven during the manufacturing and welding process, and serious water accumulation occurs in rainy days, which brings safety hazards to the weighing vehicle; seriously, the weighing platform is sunken, which directly affects weighing. , affecting the service life of the truck scale

[0004] In terms of force, when the truck scale panel bears the load, it belongs to the force structure of the simply supported beam, and the single-section steel will bend downward. If the truck scale body is not loaded, there will be Downward deformation and certain deflection will reduce the bearing capacity of the scale body

However, relatively, if there is upward deformation and arching of the scale body of the truck scale when the truck scale is not loaded, it will increase the carrying capacity of the scale body

[0005] At present, the equipment for pre-arching processing of truck scales is relatively less stable, and the effect of Yugong is not satisfactory. Therefore, it is hoped to provide a truck scale pre-arching equipment and process to solve this problem
