Directional deflection self-locking method for universal wheels of mobile traffic signal lamp

Abstract

The invention provides a directional deflection self-locking method for the universal wheels of a mobile traffic signal lamp, and the method comprises the steps that firstly a traffic police carries the universal wheels to the ground of an intersection, holds a handle to push an installation box to the central position of the intersection under the rolling action of the universal wheels, and debugs a signal lamp group and puts the signal lamp group into use; then, an electromagnetic triggering device drives the front wheels and the deflection devices corresponding to the front wheels to be switched from a free state to a restrained state, the deflection devices restrain the degrees of freedom of the front wheels, and the deflection driving mechanisms drive the front wheels to deflect leftwards by 90 degrees; and finally, the electromagnetic triggering device drives the rear wheels to switch the corresponding deflection devices from the free state to a constraint state, the deflection devices restrain the degrees of freedom of the rear wheels, and then the deflection driving mechanisms drive the front wheels and the rear wheels to synchronously deflect rightwards by 45 degrees, at the moment, the front wheels of the universal wheel deflect leftwards by 45 degrees, and the rear wheels of the universal wheel deflect rightwards by 45 degrees to complete the self-locking.

Description

technical field [0001] The invention relates to a traffic signal lamp, in particular to a directional deflection self-locking method for universal wheels of a mobile traffic signal lamp. Background technique [0002] The mobile traffic signal light mainly includes an installation box, a signal light group fixedly installed on the top of the installation box, and a universal wheel movable at the bottom of the installation box. Move to the traffic signal light and place it in the center of the road surface at the intersection to guide the road traffic. The universal wheel is for the convenience of movement, but there are also certain disadvantages. For example, the universal wheel cannot make the mobile traffic signal light stable. If it is placed on the road, especially on a slope, the traffic police need to use bricks to resist the universal wheel, which is time-consuming and labor-intensive. Moreover, even if it is placed on a horizontal road, the vibration caused by the cr...

[0002] The mobile traffic signal light mainly includes an installation box, a signal light group fixedly installed on the top of the installation box, and a universal wheel movable at the bottom of the installation box. Move to the traffic signal light and place it in the center of the road surface at the intersection to guide the road traffic. The universal wheel is for the convenience of movement, but there are also certain disadvantages. For example, the universal wheel cannot make the mobile traffic signal light stable. If it is placed on the road, especially on a slope, the traffic police need to use bricks to resist the universal wheel, which is time-consuming and labor-intensive. Moreover, even if it is placed on a horizontal road, the vibration caused by the crosswind or heavy trucks on the road will not be affected. It will cause the rolling and deflection of the universal wheel. Therefore, in order to enable the mobile traffic signal light with universal wheel to be placed on the road stably, it is necessary for the present invention to provide a mobile traffic signal light with ingenious structure, simple principle, and convenient operation and use.
