Double-mechanism warning device based on road and bridge construction

Abstract

The invention discloses a double-mechanism warning device based on road and bridge construction, relates to the technical field of warning devices, and solves problems that an existing warning devicewith an LED lamp is damaged by in-out personnel and equipment on a construction site, and the warning effect of the warning device without the LED lamp is poor at night. The double-mechanism warning device based on road and bridge construction comprises a lifting mechanism and an automatic starting and stopping mechanism, wherein the lifting mechanism is composed of an adjusting rod, a lifting gear and a shell, and the automatic starting and stopping mechanism is composed of a fixing shell and a pressing column. The device is advantaged in that a daytime warning shell and a night warning lampshell are matched, the device can play the normal warning effect no matter in the daytime or at night, the night warning lamp shell can be retracted into the daytime warning shell in the daytime, andmistaken touch and damage to an LED warning lamp in the night warning lamp shell by personnel and machines going in and out of a construction site are prevented.

Description

technical field [0001] The invention belongs to the technical field of warning devices for road construction, and more specifically relates to a dual-mechanism warning device for road and bridge construction. Background technique [0002] Warning devices are also known as construction signs and activity signs. It is used as a peripheral protection reminder for road construction sites, maintenance of municipal construction, and building construction. It can be placed where needed to guide traffic at any time to prevent accidental collisions and reduce losses. The exterior of the warning device is generally sprayed with safety signs or equipped with LED warning lights flashing safety colors to play a warning role. The safety signs are made of safety colors (safety colors are used to express the meaning of safety information such as prohibition, warning, instruction, and instructions. The specific regulations are four colors: red, blue, yellow and green. The contrasting colors...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a dual-mechanism warning device based on road and bridge construction, to solve the problem that the existing warning device with LED lights is installed at the initial position of the construction site due to entering and leaving the construction site during the daytime. There are many people and equipment on site, and LED lights are generally fragile and cannot be hidden after installation, which often causes damage to the warning device caused by people entering and leaving the construction site and equipment, resulting in the LED lights of the warning device not being able to properly warn and guide at night. The warning device without LED light can normally play the role of warning and guidance during the day, but the warning effect of the warning device without LED light at night is not satisfactory, and the practicability is not high.
