Embodiment 1

[0024] Referring to Figures 1 to 4 As shown in the drawings, a staggered overlap transition protection system at an opening of a highway guardrail, comprising: an upstream overlap guardrail 1, a self-moving guardrail 2 and a downstream transition guardrail 3 arranged in sequence along the driving direction on one side of the driving lane 4; the self-moving guardrail 2 is overlapped upstream to the rear of the upstream overlap guardrail 1 and overlapped downstream to the front of the downstream transition guardrail 3; the self-moving guardrail 2 comprises: a guardrail body, a guide rail 24 and a track wheel 23, the guide rail 24 is laid from the front of the downstream transition guardrail 3 to the rear of the upstream overlap guardrail 1, and the track wheel 23 is rotationally connected to the bottom of the guardrail body. When the self-moving guardrail 2 is opened, the self-moving guardrail 2 is pushed to translate along the guide rail 24, so that the self-moving guardrail 2 is translated to the rear of the upstream overlap guardrail 1, and at this time the field area road 5 is not blocked. The vehicle collision to the upstream end of the self-moving guardrail 2 can be avoided, and when the self-moving guardrail 2 is closed, the upstream overlap guardrail 1, the self-moving guardrail 2 and the downstream transition guardrail 3 are cooperatively stressed when the vehicle collides with the upstream overlap guardrail 1. Based on the transition mode of staggered overlap, the self-moving guardrail 2 is realized to be opened as a whole, so that the opening at the opening of the highway guardrail is more convenient, and the opening time is saved.

[0025] Please refer to Figure 2 In this embodiment, as preferred, the guardrail body is composed of two groups of frame units connected in series, and the frame unit comprises: two stand columns 21 and two crossbeams 22; the two stand columns 21 and the two crossbeams 22 form a rectangular frame, each stand column 21 is provided with a track wheel 23 at the bottom, and the track wheel 23 is above the guide rail 24.
