Novel highway guardrail
The invention provides a novel expressway guardrail which comprises a guardrail body. The guardrail body is provided with a lifting device. The lifting device comprises a first nut, a first threaded block, a screw rod, a first supporting rod, a second supporting rod, a breast board and a sliding block; the outer walls of the two ends of the screw rod are rotationally connected with the guardrail through bearings, the right end of the screw rod is fixedly connected with a first nut, the outer wall of the screw rod is in threaded connection with a first threaded block, the first threaded block is rotationally connected with one end of a second supporting rod through a pin shaft, and the other end of the second supporting rod is rotationally connected with the breast board through a pin shaft; the middle position of the second supporting rod is rotationally connected with the first supporting rod through a pin shaft, the two ends of the first supporting rod are rotationally connected with the guardrail and the breast board through pin shafts respectively, sliding blocks are fixedly connected to the two sides of the breast board, and the two sliding blocks are slidably connected with the guardrail. The height of the guardrail can be adjusted according to needs, and every two adjacent guardrails can be connected conveniently.
本发明提供了一种新型高速公路护栏，包括护栏，护栏设置有升降装置；升降装置包括第一螺母、第一螺纹块、螺杆、第一支杆、第二支杆、栏板和滑块；螺杆两端的外壁通过轴承与护栏转动相连，螺杆的右端固接有第一螺母，螺杆的外壁螺纹连接有第一螺纹块，第一螺纹块与第二支杆的一端通过销轴转动相连，第二支杆的另一端与栏板通过销轴转动相连，第二支杆的中间位置与第一支杆通过销轴转动相连，第一支杆的两端分别与护栏和栏板通过销轴转动相连，栏板两侧均固接有滑块，两个滑块均与护栏滑动相连。本发明可根据需要调节护栏的高度，且相邻两个护栏之间的便于连接。
