The platform scale can be divided into: the U-shaped steel platform scale, the channel steel platform scale, the I-beam platform scale, and the reinforced concrete platform scale (common name cement scale).
Comparison of 1U steel and channel steel.
Why choose U-shaped steel floor scales instead of channel steel floor scales?
A: 1 First, let us say that the channel scale body is made up of channel steel main beam, and then connected with a horizontal diaphragm, and then the cover plate is used at the bottom. The U-shaped steel scale body is based on the bridge principle, with U-shaped steel at the bottom to support, without the closure plate and the mold partition. In comparison, the same type of scale body, the channel steel scale weighs the U-shaped steel scale body. Interest is higher than U-shaped steel scales. The plate body of the channel scale plays a role in tension, but U-shaped steel does not.
2 From the welding point of view, U-shaped steel scales are full welding, and channel steel scales are spot welding. Therefore, the industry believes that U-shaped steel is better than channel steel.
At present, manufacturers of floor scales on the market mainly use U-shaped steels and channel steels, of which the U-shaped steel structure of the platform scale has become the mainstream in the market, the U.S., Germany, China and even the world's ground pound manufacturers have adopted U-shaped steel structure, U-shaped steel platform scales.
The 3 channel steel belongs to the third generation of weighing devices. The channel steel has two supporting beams at the bottom and the middle is empty, so the bracing performance is worse. Simply speaking, the steel structure ratio is not very reasonable. The channel steel weigher is equal to the steel plate, but the same tonnage channel steel is heavier than the U-shaped steel from the scale body weight. This truth.
U-shaped steel, the fourth generation of industrial weighing equipment, U-shaped steel scale must be equipped with equipment is a bending machine. Kelida Company adopts 600T large-scale double-acting linkage bending machine. The shearing machine has high positioning accuracy and high speed. The equipment is advanced in the same industry in the province. The price of U-shaped steel scales is more expensive than that of channel steels. The steel structure is reasonable, the rigidity is good, the strength is good, and the lateral resistance is strong, so the scale body can resist winding. ,long life. At the bottom of U-shaped steel is a U-shaped steel weighing platform designed with a bridge structure. U-shaped main beam 5-7 (designed according to tonnage and countertop dimensions) to ensure the overall rigidity of the weighing platform, the weighing platform cavity is sealed, not easy to rust, After the steel plate has been shot blasted, the epoxy zinc-rich primer and acrylic acid marine paint are used. The oil film is thick, and the thickness is 100 microns. The pressure resistance, acid resistance, alkali resistance and corrosion resistance are stronger.
2 I-beams, also known as steel beams, are long steel I-beams with an I-section and are also referred to as steel beams. I-shaped long steel bars are used for cross-sections. Its specification is waist height (h * leg width (b * waist thickness (d number, such as "worker 160 * 88 * 6" means waist height is 160 mm, leg width is 88 mm, waist thickness is 6 mm I-beam The specifications of the I-beam can also be expressed by the model number, which indicates the centimeters of the waist height, such as the I-beam with the same height of the waist of the 16# waist, if there are several different leg widths and waist thicknesses, it is necessary to add the abc on the right side of the model. For example, 32a#32b#32c#, etc. The I-beam is divided into common I-beam and light I-beam, and the specification of hot-rolled I-beam is 10-63#. 12-55# I-beam is widely used in various building structures, bridges, vehicles, supports, machinery and so on.
3 Reinforced Concrete Floor Scales Reinforced concrete weighbridge (common name cement weigher) is equivalent to full electronic weighbridge, digital weighbridge, and analog weighbridge. The biggest difference lies in the difference in scale structure. The former is a reinforced concrete structure, and the latter is an all-steel structure. The scales, junction boxes, and printer sensors used in these floor scales (the vehicle's nominal scale) are generally the same. The working principle and the lightning protection facilities are basically the same. The construction of the ground scales is the same, and there is no essential difference in function. However, the cement scale is much longer than the full steel structure in the production cycle. Therefore, if you want to use the cement scale as the platform scale, it is best to consult with the manufacturer as early as possible to avoid delaying the use of the floor scale.
Advantages of cement scales: Fundamentally solve the problems of corrosion caused by rain and sunlight, acid and alkali corrosion, and thermal expansion and contraction of structures during the use of all-steel structure loadometers, and the use of precision and service life is reduced. Corrosion ability, structural stability, self-importance, accurate positioning, no deformation, and maintenance-free are applicable to public pound stations, chemical companies, port terminals, frozen industries, and other industries that require high anticorrosion functions.
Scale body classification and performance
As an indispensable part of the scales - weighing platform, the selected data and performance will directly affect the life of the platform scale, what kind of scale is suitable for their own use? This issue has become one of the key factors in purchasing floor scales.
