Preset complete weighing narrow-strip high-speed weighing system

Abstract

The invention discloses a preset complete weighing narrow-strip high-speed weighing system. The system comprises a prefabricated member, two narrow-strip high-speed weighing table tops, a coil type vehicle separator and a data processing unit. The prefabricated member is formed by integrally pouring cement mortar and reinforcing steel bars at a time. And two narrow-strip-type high-speed weighing table tops with extended weighing table tops are buried in the prefabricated member at intervals. Two built-in narrow strip type high-speed weighing table tops are utilized to weigh the same tire of the same truck twice, the two weighing results supplement each other, and finally, the load capacity of the truck is calculated, so that the defect of incomplete weighing of a narrow strip type weighingdevice due to small contact area between the narrow weighing platforms and the tire is overcome. Therefore, the system is high in measurement precision and high in measurement result accuracy. Due tothe fact that the prefabricated member is an integrated prefabricated member and can be machined in a factory in advance, on-site installation is easy, the construction period is short, 72-hour rapidtraffic on a highway can be achieved, the technical requirement for on-site constructors is low, and the construction cost is low.

Description

technical field [0001] The invention relates to a narrow-strip high-speed weighing system, in particular to a factory-produced preset and complete-weighing narrow-strip high-speed weighing system. Background technique [0002] At present, the overloading of trucks in our country is relatively common. In order to control the overloading of trucks on highways, high-speed dynamic weighing systems are installed on some highways with serious overloading for dynamic weighing detection. The weighing devices used in the existing high-speed dynamic weighing systems include narrow-bar high-speed weighing devices, flat-plate high-speed weighing devices and piezoelectric weighing devices. [0003] The piezoelectric weighing device is easy to install and has a small amount of construction, but it is greatly affected by factors such as vehicle speed, and the measurement accuracy is low. The flat-panel weighing device has high measurement accuracy when the vehicle is running at a low spee...

Problems solved by technology

[0007] However, installing two adjacent narrow-strip high-speed weighing devices at intervals on the expressway has higher requirements on the construction environment. It is required that the weighing platforms of the two narrow-strip high-speed weighing devices must be on the same level. The heavy platform and the road between the two weighing platforms must be on the same level without bumps, otherwise the measurement accuracy will be seriously affected, and the installation level of the construction personnel is high.

In addition, the requirements for the construction period are relatively strict. The construction period cannot exceed 72 hours, and the expressway cannot be closed for a long time to affect traffic.
