A mobile guardrail and transport, installation and construction trolley

Abstract

The invention discloses a mobile guardrail and a transport, installation and construction trolley, comprising: a separation board, arranged longitudinally along the yellow line of the road; several guardrails, respectively arranged on one side of the separation board, and two adjacent guardrails Hinged on the opposite sides of a support rod through the first hinge, the bottom of the support rod is provided with a first roller; the buffer mechanism, one end of which is connected to the isolation plate, and the other end is connected to the guardrail or the support rod; the buffer layer, Evenly set on the side of the isolation board facing the guardrail. In the present invention, an isolation plate is arranged above the yellow line of the road, and a buffer layer is arranged on the isolation plate, and the guardrail on the road is connected through the buffer mechanism, so that when the vehicle collides, the guardrail can offset the impact of a part of the vehicle through the buffer mechanism. Energy, and then through the buffer layer to completely reduce the energy of the vehicle, so that when the car collides, the occurrence of casualties can be reduced.

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
