Longitudinal and transverse type limiting structure of electric automobile scale

Abstract

The invention provides a longitudinal and transverse four-directional limiting mechanism. A longitudinal and transverse type limiting structure of an electric automobile scale comprises a base and a weighing platform on the base and is characterized in that limiting plates which are assembled together with the weighing platform through first bolts and first nuts are arranged at the two ends, in the longitudinal direction, of the weighing platform respectively, and two pieces of box iron which is assembled together with the weighing platform through second bolts and second nuts is arranged at the two ends, in the transverse direction, of the weighing platform respectively. The aim of adjusting a gap between the weighing platform and the base can be easily and rapidly achieved when the bolts and the nuts are adjusted in the four longitudinal and transverse directions through visual inspection to be matched with one another, and safety and reliability of weighing of the automobile scale are ensured.

Description

technical field [0001] The invention relates to the field of truck scales, in particular to an electronic truck scale vertical and horizontal limiting structure. Background technique [0002] The electronic truck scale is composed of a weighing platform, a sensor, and a digital display instrument. It is installed on a concrete foundation. The installation method is divided into shallow foundation pit (underground embedded) and no foundation pit (ground type). There are gaps around the periphery (shallow foundation pit type installation) and both ends of the approach slope (ground type installation), so that there is no roof between the foundation pit and the end of the approach slope (hereinafter collectively referred to as "base") when the weighing platform on the car is loaded and shakes To ensure the accuracy of weighing data. Existing truck scales generally adopt a two-way limit structure. The limit structures at both ends of the two directions can only limit the fr...

AI Technical Summary

Problems solved by technology

Existing truck scales generally adopt a two-way limit structure. The limit structures at both ends of the two directions can only limit the front and rear two-way shaking. When the car drives horizontally on the weighing platform, the lateral shaking of the weighing platform is likely to cause the horizontal collision with the base. It directly affects the weighing accuracy, greatly shortens the service life of the sensor, and increases the maintenance cost of the user

There are also some manufacturers who use multi-sided semi-closed limit plates welded to the foundation embedded parts, which not only complicates the process, takes time and effort for installation and maintenance, but also increases the cost of raw steel plates
