Design method of hoisting movable arm mechanism of pile cutting machine
The invention discloses a design method of a hoisting movable arm mechanism of a pile cutting machine, which comprises the following steps of: selecting and determining a hydraulic pile cutting device according to the characteristics of a pile type, and determining a pile head pulling construction acting force F 'N; designing a hoisting movable arm and a movable arm support; parameters of the double-acting hydraulic oil cylinder are determined, and the parameters comprise the design length LY0 of the double-acting hydraulic oil cylinder, the design stroke LY of the oil cylinder and the variable range [-FYmax, FYmax] of the load FY; determining parameters of the spring booster device, wherein the parameters comprise the sizes of the first component and the second component, the original length LT0 of the spring and the rigidity KT; according to the lifting movable arm mechanism of the pile cutting machine adopting the design method, gravitational potential energy generated when the lifting movable arm descends can be converted into elastic potential energy through the arrangement of the spring power assisting device, the elastic potential energy is converted into gravitational potential energy when the lifting movable arm ascends, and therefore energy consumption is reduced, thrust and tension of the double-acting hydraulic oil cylinder can be fully utilized, and the lifting movable arm can be stably lifted. The equipment cost is reduced.
本发明公开了一种截桩机吊装动臂机构的设计方法，所述设计方法包括如下步骤：根据桩型本身特征，选择确定液压截桩装置，并确定拔桩头施工作用力F’N；设计吊装动臂和动臂支座；确定双作用液压油缸的参数，包括双作用液压油缸的设计长度LY0、油缸设计行程△LY、荷载FY可变范围[‑FYmax,FYmax]；确定弹簧助力装置参数，包括第一构件、第二构件的尺寸，弹簧的原长LT0，刚度为KT。采用该设计方法的截桩机吊装动臂机构，通过设置弹簧助力装置可以将吊装动臂下降时的重力势能转化为弹性势能，在吊装动臂抬升时再将弹性势能转化为重力势能，从而降低能源消耗，并能充分利用双作用液压油缸的推力和拉力，降低设备成本。
