Movable guardrail and transportation and installation construction trolley

Abstract

The invention discloses a movable guardrail and transportation and installation construction trolley which comprises: a partition plate longitudinally arranged along the yellow line trend of a road; aplurality of guardrails which are arranged on one side of the partition plate respectively, wherein every two adjacent guardrails are hinged to the two opposite side faces of one supporting rod through first hinge pieces respectively, and first rolling wheels are arranged at the bottoms of the supporting rods; a buffer mechanism, wherein one end of the buffer mechanism is connected to the partition plate, and the other end of the buffer mechanism is connected to the guardrails or the supporting rods; and buffer layers which are uniformly arranged on one surface, facing the guardrails, of thepartition plate. The partition plate is arranged above the yellow line of the road, meanwhile, the buffer layer is arranged on the partition plate, and the guardrails located on the road is connectedthrough the buffer mechanism, so that when a vehicle collides, the guardrails can counteract part of energy of the vehicle through the buffer mechanism, and then the energy of the vehicle is completely reduced through the buffer layer; therefore, casualty accidents of people can be reduced when the automobile is collided.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a mobile guardrail and a transport, installation and construction trolley. Background technique [0002] On the current road, there will be a row of guardrails to divide the road into left and right parts at the middle of the yellow line in the height and length direction, so that vehicles traveling in opposite directions on the road can be diverted, so that certain The degree of guarantee of the safety of the vehicle when exercising. In actual use, once a vehicle has a traffic accident, there is a high probability that it will collide with the guardrail in the middle of the road, and the current guardrail only has the function of separating the road without corresponding anti-collision function. When colliding with the guardrail, the current guardrail cannot withstand the impact force of the vehicle and cause damage. At the same time, the damaged guardrail will enter the...

Problems solved by technology

In actual use, once a vehicle has a traffic accident, there is a high probability that it will collide with the guardrail in the middle of the road. However, the current guardrail only has the function of separating the road and has no corresponding anti-collision function. When colliding with the guardrail, the current guardrail cannot withstand the impact force of the vehicle and cause damage. At the same time, the damaged guardrail will enter the interior of the vehicle under the strong impact force of the vehicle, which is very likely to hurt the people in the vehicle. Cause secondary injury, in severe cases, it will also cause a certain degree of casualties, and may cause collisions to vehicles traveling in the opposite direction
