The invention provides a multistage anti-collision buffer device applied to a road construction vehicle and the anti-collision construction vehicle. The multistage anti-collision buffer device comprises a vehicle body and a first buffer mechanism. The vehicle body comprises an upper vehicle seat, a front vehicle frame, a rear vehicle frame, an inner connecting plate and a traction frame, a first connecting shaft on the front vehicle frame is rotationally inserted into a fixed clamping barrel in a penetrating mode and locked through an upper limiting plate A and a lower limiting plate A, and asliding groove is formed in the other end of the upper vehicle seat; a second buffer mechanism comprises a movable clamping barrel, the movable clamping barrel is arranged in the sliding groove, and passes through a clamping plate clamping position; a second connecting shaft on the rear frame is rotationally inserted into the movable clamping barrel in a penetrating mode and locked through an upper limiting plate B and a lower limiting plate B. The first buffer mechanism is connected to the rear end side of the rear frame. When collision occurs, a buffer plate B of the arc-shaped structure firstly plays a role in buffering, secondary buffering is conducted through the rotating performance of a buffer plate A and the elastic force of a buffer springs A, buffering and force unloading are conducted through four sets of buffer springs B in the second buffer mechanism, and buffering is further conducted through the rear end of a third buffer beam.

    本发明提供应用于道路施工车的多级防撞缓冲装置及防撞施工车,包括车体,第一缓冲机构;所述车体包括上车座、前车架、后车架、内连板与牵引架,前车架上的第一连接轴转动穿插在固定卡筒上并通过上下两组限位板A锁位,上车座另一端设有滑槽,所述第二缓冲机构包括有活动卡筒,活动卡筒滑动安装在滑槽内并通过卡板卡位,后车架上的第二连接轴转动穿插在活动卡筒上并通过上下两组限位板B锁位,所述第一缓冲机构连接在后车架的后端侧。在发生碰撞时,弧形结构的缓冲板B首先起到缓冲作用,并通过缓冲板A的旋转性以及缓冲弹簧A的弹力进行二次缓冲,利用第二缓冲机构中的四组缓冲弹簧B进行缓冲并卸力,通过第三缓冲梁的后端进一步进行缓冲。
