The invention discloses a shear lifting mechanism type trailer. A plurality of installing bases on trailer guardrails on the two sides of a trailer frame of a trailer chassis are connected with a trailer bottom plate through shear fork type jacking mechanisms, a hydraulic cylinder control system of a remote control hydraulic control mechanism drives the shear fork type ejecting mechanisms to expand, the trailer bottom plate is lowered to the ground, a small crane hydraulic control system controls a small crane to put down a lifting hook for hooking up a steel wire rope of front wheels of an accident vehicle and to lift up the lifting hook and the front portion of the accident vehicle, a small crane telescopic arm retracts and pulls the accident vehicle onto the trailer bottom plate, and the shear fork type ejecting mechanism then retracts and lifts the trailer bottom plate up to an original position; and through reverse operation, the accident vehicle can be detached; the shear fork type ejecting mechanism stably performs lifting, the accident vehicle can be kept balanced all the time in the lifting, traction and transportation process, the trailer guardrails can also be used for limiting and fixing the accident vehicle and preventing the accident vehicle from inclining or disengaging in the transportation process, so that the secondary accident caused by secondary collision isavoided, stability and reliability are realized in the transportation process, the structure is simple and compact, manufacturing, installation and use and operation are convenient, and cost is low.
本发明的剪升机构式拖车,拖车底盘的拖车框架两侧边拖车护栏上多个安装座通过剪刀叉式顶升机构连接拖车底板,遥控液压控制机构的液压油缸控制系统驱动剪刀叉式顶升机构展开,将拖车底板降低至地面,小吊液控系统控制小吊机放下吊钩钩挂故事汽车前轮上的钢丝绳,将挂钩及事故汽车前部吊起,小吊机伸缩臂回缩将事故汽车拉到拖车底板上,剪刀叉式顶升机构再收缩将拖车底板上升至原始位置;反向操作可卸下事故汽车;剪刀叉式顶升机构升降平稳,起吊、牵引、运输过程中能够始终保持事故汽车平衡,拖车护栏还可以用于限位固定事故汽车,防止在运送过程中倾斜或脱落,避免发生二次碰撞造成二次事故,运输过程稳定可靠,结构简单紧凑,生产制造、安装使用操作方便,成本低廉。
