The invention relates to the field of lifting appliances, in particular to an excavator guide wheel production lifting appliance which comprises a linear transmission mechanism, an electric rod and a mounting frame, two first mounting plates are welded to the outer wall of one side of the mounting frame, a motor is fixedly mounted on the outer wall of one of the first mounting plates, a first threaded rod is rotatably connected between the two first mounting plates, and a second threaded rod is rotatably connected between the two first mounting plates. The first threaded rod is fixedly installed with the output end of the motor, a threaded block is in threaded connection with a rod body of the first threaded rod, the rotating driving gear drives the guide wheel to rotate, so that the guide wheel is switched from the vertical state to the horizontal state, and the step of manually overturning the guide wheel by a worker is omitted; the clamping block moves in the direction close to the guide wheel along the third sliding rod, so that the clamping force of the clamping block on the guide wheel is increased, the clamping force of the clamping block is related to the inertia of the guide wheel, the larger the inertia acting force of the guide wheel is, the larger the clamping force of the clamping block is, and the more difficult the guide wheel to fall off from the lifting appliance in the overturning process is.
本发明涉及吊具领域,尤其涉及一种挖掘机引导轮生产用吊具,包括线性传动机构、电动杆和安装框,所述安装框一侧外壁上焊接有两个安装板一,其中一个所述安装板一外壁上固定安装有电机,两个所述安装板一之间转动连接有螺纹杆一,且螺纹杆一与电机输出端固定安装,所述螺纹杆一杆体上螺纹连接有螺纹块,旋转的主动齿轮带动引导轮进行旋转,使得引导轮由直立状态切换为水平状态,省去了工人手动翻转引导轮的步骤,夹持块会沿着滑杆三向靠近引导轮的方向进行移动,使得夹持块对引导轮的夹持力增大,夹持块的夹持力度与引导轮的惯性相关,引导轮的惯性作用力越大,夹持块的夹持力度越大,使得翻转过程中的引导轮越不易从吊具上脱落。
