The invention discloses a shear fork mechanism which comprises a shear fork assembly, a rear frame wheel seat and a front frame wheel seat. The shear fork assembly comprises a first shear fork arm assembly, a second shear fork arm assembly and multiple connecting shafts. The first shear fork arm assembly and the second shear fork arm assembly are connected through the multiple connecting shafts. The first shear fork arm assembly is provided with a first hinged point. The second shear fork arm assembly is provided with a second hinged point. A first hydraulic cylinder and a second hydraulic cylinder are arranged on the rear frame wheel seat. The moving end of the first hydraulic cylinder is connected with the first hinged point in the first shear fork arm assembly, and the moving end of thesecond hydraulic cylinder is connected with the second hinged point in the second shear fork arm assembly. According to the shear fork mechanism, the dual hydraulic cylinders are arranged to drive ashear fork component, and stability in the stretching and contracting process of the shear fork component is guaranteed; and the dual hydraulic cylinders are arranged obliquely, so that the first hydraulic cylinder and the second hydraulic cylinder achieve point-to-point contact with the shear fork arm assemblies, and abnormal sounds are prevented from being produced in the stretching and contracting process of the shear fork component.

    本发明公开了一种剪叉机构,其包括剪叉组件、后架轮座和前架轮座;剪叉组件包括第一剪叉臂总成、第二剪叉臂总成和多个连接轴;所述第一剪叉臂总成和第二剪叉臂总成通过多个连接轴相连;所述第一剪叉臂总成设置有第一铰接点,所述第二剪叉臂总成设置有第二铰接点;所述后架轮座设置有第一液压缸和第二液压缸,所述第一液压缸的活动端与第一剪叉臂总成中第一铰接点相连,所述第二液压缸的活动端与所述第二剪叉臂总成中第二铰接点相连;本发明公开了一种剪叉机构,其设置有双液压缸驱动剪叉组件,保证剪叉组件伸缩过程的稳定性;双液压缸倾斜设置并使得第一液压缸和第二液压缸与剪叉臂总成实现点与点接触,避免剪叉组件在伸缩过程中产生异响。
