It should be understood that the implementation of the present utility model is not limited to the following embodiments, and any form of modification and / or change made to the present utility model will fall within the protection scope of the present utility model.

[0018] In the present utility model, unless otherwise specified, all parts and percentages are in weight units, and the equipment and raw materials used can be purchased from the market or are commonly used in the art. The methods in the following embodiments are conventional methods in the art unless otherwise specified. The components or equipment in the following embodiments are all standard parts or components known to those skilled in the art unless otherwise specified, and their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0019] Example 1:

[0020] As Figure 1 、 2 shown, the present utility model provides a technical solution, a guardrail emergency escape device, which includes side guardrail plates 1 on both sides and an intermediate guardrail plate 2 located between the two side guardrail plates 1. The side guardrail plates 1 are fixedly installed on one side of the road through the first upright posts 3 and bolts on the inner side. One end of the inner side surface of the intermediate guardrail plate 2 is fixedly installed with a vertically arranged steering sleeve 4. The inside of the steering sleeve 4 is hollow, and a second upright post 5 is also fixedly installed on one side of the road. The steering sleeve 4 is sleeved on the outer side wall of the second upright post 5. The intermediate guardrail plate 2 can rotate around the second upright post 5 through the steering sleeve 4. A universal wheel 7 is provided at one end of the inner side surface of the intermediate guardrail plate 2 away from the steering sleeve 4 through a support column 6. The lower end of the support column 6 is detachably and fixedly connected to the universal wheel 7 through a bolt; the intermediate guardrail plate 2 and the side guardrail plate 1 are fixedly connected through a positioning component, and the separation between the intermediate guardrail plate 2 and the side guardrail plate 1 can be quickly realized through the positioning component.

[0021] Example 2:

[0022] As Figure 1 、 2 shown, the present utility model provides a technical solution, a guardrail emergency escape device, which is different from that of Example 1 in that there are two sets of left and right positioning components, each consisting of a first connecting steel plate 8, a second connecting steel plate 9, a first positioning sleeve 10 and a second positioning sleeve 11. The first connecting steel plate 8 is fixedly installed on the inner side surface of the side guardrail plate 1 through a bolt. The second connecting steel plate 9 is fixedly installed on the inner side surface of the intermediate guardrail plate 2 through a bolt. The first positioning sleeve 10 is vertically welded and fixed on the inner side surface of the first connecting steel plate 8. The second positioning sleeve 11 is vertically welded and fixed on the inner side surface of the second connecting steel plate 9. And the first positioning sleeve 10 and the second positioning sleeve 11 correspond to each other, and the intermediate guardrail plate 2 and the side guardrail plate 1 are fixed by a positioning pin inserted on the first positioning sleeve 10 and the second positioning sleeve 11.

[0023] Specifically, the first connecting steel plate 8 and the second connecting steel plate 9 are arranged in a staggered manner up and down. In this embodiment, the universal wheel 7 is installed on the left side of the middle guardrail plate 2, and the steering sleeve 4 is installed on the right side of the middle guardrail plate 2; the first connecting steel plate 8 of the left positioning assembly extends out of the side guardrail plate 1, and the second connecting steel plate 9 does not extend out of the middle guardrail plate 2. When the middle guardrail plate 2 and the side guardrail plate 1 are connected together, the side of the left end of the middle guardrail plate 2 away from the driving lane contacts the side of the corresponding side guardrail plate 1 facing the driving lane; the first connecting steel plate 8 of the side positioning assembly does not extend out of the side guardrail plate 1, and the second connecting steel plate 9 extends out of the middle guardrail plate 2. When the middle guardrail plate 2 and the side guardrail plate 1 are connected together, the side of the right end of the middle guardrail plate 2 facing the driving lane contacts the side of the corresponding side guardrail plate 1 away from the driving lane; the driving direction is as Figure 3 shown. The purpose of such a design is to maintain the protective function of the guardrail.

[0024] In case of an emergency, pull out the positioning pins at both ends, and open the middle guardrail plate 2 towards the lane side near the universal wheel to provide a safe escape passage for people. After the rescue is over, reset the middle guardrail plate 2 and insert the positioning pins, which is simple to operate.

[0025] Embodiment 3:
