The invention relates to a chassis lifting appliance capable of switching the length of a supporting arm, which comprises a lifting appliance supporting arm system consisting of a pair of lifting appliance supporting arms, and the lifting appliance supporting arm system is fixed at the bottom of a lifting appliance holding arm system through a fastening flange; the lifting appliance supporting arm comprises a flange plate, and the reinforcing rib and the fixed supporting block are integrally fixed on the flange plate; the L-shaped connecting plate is fixed with the fixed supporting block and the reinforcing rib; the two linear guide rail sliding blocks are fixed to the fixed supporting block, the rail ends of the linear guide rails are fixed to the supporting arm sliding blocks, and the supporting arm sliding blocks are connected with the end plates. The sliding block positioning plate is connected with the fixed supporting block; the positioning pin is fixed with the corbel sliding block, a spring structure is arranged in the positioning pin, and the pin can enter any one of the three round holes of the sliding block positioning plate to lock the position of the corbel sliding block. The positions of the lifting appliance supporting arms can be selectively adjusted, and switching of the lifting appliance supporting arms with different Y-direction lengths can be achieved; through switching of the lifting appliance supporting arms, the same lifting appliance can meet the transfer and process requirements of multiple platform vehicle models, and the transformation investment cost and the transformation period of the lifting appliance when a new platform vehicle model is on line are reduced.
本发明涉及一种可切换托臂长度的底盘吊具,包括一对吊具托臂组成的吊具托臂系统,其通过紧固法兰固定于吊具抱臂系统底部;吊具托臂包括法兰板,加强筋与固定托块整体固定在法兰板上;L型连接板与固定托块及加强筋固定;两个直线导轨滑块与固定托块固定,直线导轨轨道端与托臂滑块固定,托臂滑块与端板连接;滑块定位板与固定托块;定位销与托臂滑块固定,其内装有弹簧结构,销子能进入滑块定位板三个圆孔中的任意一个,对托臂滑块的位置进行锁定。本发明吊具托臂位置可选择调整,可以实现不同Y向长度吊具托臂的切换;通过吊具托臂的切换,同一个吊具能实现多平台车型的转运和工艺需求,降低新平台车型上线时吊具的改造投资成本和改造周期。
