Truck scale transition device for highway overload control system and installation method of device

Abstract

The invention discloses a truck scale transition device for a highway overload control system and an installation method of the device. The truck scale transition device comprises a guide plate I, a guide plate II and a truck scale body positioned therebetween, a connecting plate I and a connecting plate II are arranged on two sides of the truck scale body respectively, and the scale body is fixedly installed on a mobile base. When the truck scale transition device used by the highway overload control system is dismounted, it is only required to dismount the scale body on the mobile base, a truck scale used by the highway overload control system can be repeatedly used; and the surface of the scale body is provided with a square notch, a transition plate is erected in the square notch through a spring I and a spring II, and the transition plate is made to incline to a certain degree in the vehicle driving direction during weighing, so that a weighed vehicle bears certain resistance whendriving on the truck scale, and is decelerated, further the vehicle is buffered and transitioned on the truck scale, the weighing position of the vehicle on the truck scale is accurately controlled,and the weighing precision of the truck scale is improved.

Description

technical field [0001] The invention belongs to the technical field of highway overload control, in particular to a truck scale transition device used in a highway overload control system and an installation method thereof. Background technique [0002] In recent years, over-limit transportation has overwhelmed highways and bridges, greatly reducing the service life of roads and bridges. Existing ways to control overruns are mainly to detect vehicle weight and outer contour dimensions at the entrance of the expressway, and then prohibit or unload the goods. However, due to different law enforcement efforts in various places, there are still a large number of overrun vehicles entering the expressway. According to the actual needs of overrunning work, there is an urgent need for a device that can effectively identify overrun vehicles driving on the road. Among them, overrun vehicles refer to cargo transport vehicles with overweight, overheight, overwidth and overlength. [00...

AI Technical Summary

Problems solved by technology

For example, the Chinese patent application 201510074299.X is aimed at the detection of vehicles at the entrance of the toll station, which is used to prevent overloaded vehicles from entering the expressway. The platform scale is inconvenient to disassemble and assemble, and the existing truck scales used in the road overtaking system in the highway system are commonly used as platform-type axle load scales. The equipment cost of scale-type axle load scales is low and easy to install, but the existing The truck scale transition device used in the road overtaking system still has the following deficiencies:

[0004] 1. The platform-type axle load scale has a large overall thickness and low measurement accuracy. It needs a deep foundation pit on the road during installation. The construction is relatively large, and a certain gap is required between the weighing platform and the frame, which is easy to cause rainwater The deposition of sediment, etc. After a period of use, the foundation pit needs to be cleaned, which not only affects the normal operation of the road, but also has a high cost. It is difficult to dismantle and has great limitations;

[0005] 2. The existing truck scale transition device used in the highway overrunning system does not set a deceleration device and a weighing buffer mechanism for the vehicle when the vehicle is introduced into the truck scale body, which will easily cause the weighing vehicle to deviate from the weighing position and affect the vehicle. The weighing accuracy and service life of the scale;

[0006] 3. Existing truck scale transition devices used in highway overtaking control systems are usually installed at important locations such as intersections, but none of the existing truck scales is equipped with a reverse anti-punching device, which reduces the practicability of the truck scale
