Multifunctional full-hydraulic electric control dragline excavator and dragging steel rope guiding device
The invention belongs to the technical field of engineering vehicles, and particularly provides a multifunctional full-hydraulic electric control dragline excavator and a dragging steel rope guiding device. A multifunctional full-hydraulic electric control dragline excavator comprises a rotary platform device, an operation arm, a variable-amplitude supporting frame, a variable-amplitude pulley device and a construction end, one end of the variable-amplitude supporting frame is hinged to the root of the operation arm, the other end of the variable-amplitude supporting frame is fixedly connected with one end of a suspension cable, and the other end of the suspension cable is fixedly connected with the top end of the operation arm; a steel rope pulling guide device comprises a connecting rack, a base, a pull rod, a guide pin shaft, a rotating base and a rotating pulley block. The variable-amplitude supporting frame is installed at the root of the operation arm frame, under the condition of the same size form of the supporting frame structure, the angle between the variable-amplitude guy rope and the axis of the arm frame is greatly improved, and the stress state of the arm frame is improved. The steel rope pulling guide device is simple in structural form, large in transmission force, safe, reliable and capable of being flexibly and smoothly self-adjusted along with the change of the in-out angle of the steel rope.
本发明属于工程车辆技术领域，特别提供了一种多功能全液压电控拉铲挖掘机及拉拽钢绳导向装置。一种多功能全液压电控拉铲挖掘机，包括回转平台装置、作业臂、变幅撑架、变幅滑轮装置和施工端，变幅撑架的一端铰接于作业臂的根部，变幅撑架的另一端与悬索的一端固定连接，悬索的另一端与作业臂的顶端固定连接；一种拉拽钢绳导向装置，包括连接机架、基座、拉杆、导向销轴、旋转基座和旋转滑轮组。变幅撑架安装在作业臂架根部，在撑架结构同等尺寸形式条件下，大大改善变幅绷绳与臂架轴心线的角度，改善了臂架的受力状态。拉拽钢绳导向装置的结构形式简单、传递力大、安全可靠，且能够灵活顺畅的随钢绳出入角度变化自调整。
