Description

Technical Field

[0001] The present invention relates to the technical field of bridge detection, and particularly to a bridge vehicle weight detection device. Background Art

[0002] When a vehicle passes a bridge in the prior art, it is necessary to detect its weight to prevent overweight from endangering the stability of the bridge. The weight detection of automobiles usually relies on platform scales. Currently, most installation methods of platform scales are divided into two types: buried and placed. Although the buried platform scale does not hinder vehicle passage and is simple and efficient, it is easily damaged under the action of vehicle gravity, and it is inconvenient to repair when a failure occurs. And some placed platform scales lack limit fixing measures and are prone to shift when a vehicle passes, affecting the actual detection operation, with poor practicability and being not conducive to popularization and use.

[0003] In the prior art patent CN113188640A, a bridge vehicle weight detection device is disclosed, which relates to the technical field of bridge detection. The bridge vehicle weight detection device includes a platform scale body. A bearing plate is fixedly installed at the bottom of the platform scale body. A lifting mechanism is arranged below the bearing plate. A driving mechanism is arranged outside the lifting mechanism. A protection mechanism is arranged below the lifting mechanism. Limit connection mechanisms are arranged on both sides of the platform scale body. Two groups of conical guiding platforms are fixedly installed on the top of the bearing plate and are respectively attached to both sides of the platform scale body. The bridge vehicle weight detection device adopts a lifting structure design, which is convenient to lift the platform scale body from the ground for maintenance operations when a failure occurs in the platform scale body, improving the overall practicability of the device, meeting various requirements during use, not requiring complex and cumbersome removal operations on the platform scale body during a failure, reducing the difficulty of maintenance operations, and enhancing the actual use experience.
