The invention discloses a four-wheel linkage type trolley with a radius adjustable function. The four-wheel linkage type trolley comprises a supporting bottom frame, universal driving shafts capable of rotating are installed at the four corners of the supporting bottom frame, first connecting rods are fixedly connected to the upper portions of the universal driving shafts, wheel shafts are connected to the outer sides of the lower portions of the universal driving shafts, and wheels are installed on the wheel shafts; the bent pipe winding device is simple in design structure and convenient and fast to use, the movement track of the whole trolley can be changed by rotating the driving rod, winding work of bent pipes with different radians can be met, and the bent pipe winding device is convenient to use and high in practicability. And through the four-wheel linkage function, the movement track of the trolley can be effectively matched with the radian of the bent pipe, the situation that the coating machine above the trolley collides with the bent pipe is prevented, the coating quality is improved, and the working efficiency is also improved.

    本发明公开了一种具有半径可调功能的四轮联动式小车,包括支撑底架,支撑底架的四角位置处均安装有可进行转动的联动轴,联动轴的上方位置固定连接有第一连杆,联动轴的下方外侧位置连接有轮轴,轮轴上安装有车轮;小车同侧位置的两个第一连杆上均铰接有第二连杆,两个第二连杆的末端均铰接有第三连杆,本发明设计结构简单、使用便捷,能够通过旋转驱动杆来实现整个小车运动轨迹的改变,有利于满足不同弧度的弯管缠绕工作,且四轮联动的功能能够有效的实现小车运动轨迹与弯管弧度的匹配,防止小车上方的包覆机与弯管之间产生碰撞的情况出现,既提高了包覆的质量,也提高了工作效率。
