With the development of weighing technology, the sensor technology of weighing instrument is becoming more and more digital. Whether the static weighing system of vehicle weighing or the static weighing system of axle weighing is developing towards the digital sensing technology. Today we will introduce explosion-proof electronic truck scale and hydraulic flip-flop electronic truck scale.
The explosion-proof electronic truck scale is an electronic truck scale used in explosion dangerous environment. First, the explosion-proof grade of the environment should be assessed by the explosion-proof department according to the dangerous degree of explosion on the spot. Then, according to the explosion-proof grade and dangerous area, the corresponding electronic vehicle temporary and explosion-proof kit should be selected to form the explosion-proof electronic vehicle scale.
Its structure includes weighing sensor, explosion-proof junction box, safety grid component (no safety grid component in dust environment) and weighing display controller. It can also be connected with the weighing display controller of the system in the safety zone by large screen display and computer.
This kind of truck scale is used in dangerous places with explosive gases, such as petroleum, chemical industry, medicine and so on. The commonly used types are intrinsically safe type, compound type and flameproof type:
(1) Intrinsically safe
This type of weighing display and safety gate components are installed in the safety zone. Instruments are connected by the safety gate and the bearer in the dangerous zone. The rest weight sensor and explosion-proof junction box are in dangerous places. The safety gate is the associated equipment. Its function is to prevent the non-essential weighing display stubble producer from adversely affecting the intrinsically safe weighing sensor and junction box.
(2) Duplex safe type
Loaders, weighing sensors, safety grids and weighing display controllers are all installed in flameproof enclosures and placed in dangerous areas.
This truck scale is an organic platform of hydraulic technology and modular electronic truck scale. It is suitable for automatic unloading of granular grain such as wheat, soybean, corn, peanut and rice in various grain warehouses and processing factories. It is also widely used in chemical, metallurgical, mining and all units and departments with bulk material receiving operations.
Heavy trucks are instructed to turn up the platform along the guide rail. After the vehicle is in position, the gear is lifted and the gear is blocked from the rear wheel of the vehicle. The main lifting cylinder is raised so that the turning platform can reach the specified angle, and the bulk material in the vehicle can be removed in the process. When the bulk material is wiped clean, the turning plate platform falls into place, the wheel retainer is retracted, and the truck scale opens the turning plate platform along the guide rail to complete the whole wiping process.
Its main structure:
(1) Turn-over platform: H-section steel is used as the main beam, the whole structure has enough strength and rigidity, and the deformation during lifting is very small. It is used to load the truck, and is equipped with automobile guide rail and wheel retainer.
(2) Main hoisting cylinder: Two multi-stage telescopic cylinders are arranged in one line, which ensures the lifting force, improves the stability of equipment and the safety and reliability of equipment operation.
(3) Hydraulic control system: It consists of hydraulic pump station, hydraulic circuit and control elements. The main control components of hydraulic system are imported high-quality components, which can ensure that no oil leakage occurs during long-term operation, and the system has the function of interlocking.
(4) Electrical control system: small-scale PLC control, with safety interlocking function. In the event of power outage or misoperation, the equipment will not cause misoperation and danger.
