The invention provides a supporting wheel mechanism for realizing overturning in a reach forklift and the forklift, and the supporting wheel mechanism comprises a mounting bracket connected to a supporting leg, a rotating shaft extending along a second direction is arranged on the mounting bracket, and a first chain wheel and a locking block sleeve the part of the rotating shaft, which is positioned on the inner side of the mounting bracket at an interval; the part, positioned on the outer side of the mounting bracket, of the rotating shaft is fixedly connected to a vertical swing arm; the sliding block and the locking block which are arranged on the rotating shaft on the inner side of the mounting bracket in a sleeving manner are respectively provided with a locking mechanism for matched locking on the opposite side surfaces; supporting wheels connected to the supporting legs through pivotal shafts are sleeved with second chain wheels; the first push plate and the second push plate are connected to the door frame and are linked with the door frame; the end, close to the sliding block, of the second push plate can make contact with the sliding block and push the sliding block to move in the direction away from the locking block when moving in the first direction so that the supporting wheel can at least turn over between the vertical position and the horizontal position located in the front. According to the supporting wheel mechanism, the gravity center of the forklift can move backwards.

    本发明提供一种在前移式叉车中实现翻转的支撑轮机构及叉车,其中支撑轮机构包括:连接至支腿的安装支架设置有沿第二方向延伸布置的旋转轴,旋转轴位于安装支架内侧的部分间隔套设第一链轮和锁块,旋转轴位于安装支架外侧的部分固接至竖向的摆臂;套设在安装支架内侧的旋转轴上的滑动块和锁块在相对的侧面分别设置用于配合锁紧的锁紧机构;经由枢转轴连接至支腿的支撑轮套设第二链轮;连接至门架并与门架联动的第一推板和第二推板;第二推板靠近滑动块的一端沿第一方向移动时能够接触滑动块并推动滑动块向远离锁块的方向移动,以使支撑轮至少在竖直位置和位于前方的水平位置之间翻转。根据本发明提供的支撑轮机构,可实现叉车重心后移。
