Concrete movable guardrail for expressway runway
The invention relates to a concrete movable guardrail for expressway runway, The concrete movable guardrail comprises a guardrail body internally provided with an installation cavity, a mechanical lifting device is arranged in the installation cavity, the mechanical lifting device comprises at least two levers hinged to the guardrail body, and the mechanical lifting device further comprises an adjusting screw rod capable of moving up and down. The bottom of the adjusting screw rod is used for being matched with the upper ends of the corresponding levers in an abutting mode so that the levers can rotate around the hinge axes of the levers, and lever transmission gears are fixed to the bottoms of the levers. The mechanical lifting device further comprises walking mechanisms corresponding toall levers one by one. Each walking mechanism comprises a guardrail transmission gear rotationally assembled on the guardrail body and a transmission rack assembled on the guardrail body in a guidingand moving mode, the guardrail transmission gear is in meshing transmission with the transmission rack and the lever transmission gear, and universal wheels are arranged at the bottom of the transmission rack. The invention provides a movable concrete guardrail for an expressway runway.
本发明涉及一种高速公路飞机跑道混凝土活动护栏，包括内设有安装腔的护栏本体，安装腔中设置有机械举升装置，机械举升装置包括至少两个与护栏本体铰接相连的杠杆，机械举升装置还包括能够上下移动的调节螺杆，调节螺杆的底部用于与对应杠杆的上端顶压配合以使杠杆绕其铰接轴线转动，杠杆的底部固定有杠杆传动齿轮，机械举升装置还包括与各杠杆一一对应布置的行走机构，行走机构包括转动装配于所述护栏本体上的护栏传动齿轮和导向移动装配于护栏本体的传动齿条，护栏传动齿轮与所述传动齿条和杠杆传动齿轮咬合传动，传动齿条的底部设置有万向轮。本发明提供了一种能够移动的高速公路飞机跑道混凝土活动护栏。
