Early warning large arm jacked type electric shovel and early warning method
The invention provides an early warning large arm jacked-up type electric shovel and an early warning method. The electric shovel comprises a large arm and an operation room, and the large arm is hinged to the operation room; the coupling structure and the buffer early warning structure are matched to be used for monitoring whether the big arm is jacked up or not; the coupling structure comprises a pressure push rod, one end of the pressure push rod is fixed to the pressure plate, the other end of the pressure push rod is in threaded connection with a U-shaped connector, the other end of the U-shaped connector is hinged to the push rod through a pin, the other end of the push rod is connected with a large arm cross rod, and the large arm cross rod is rotationally installed on the large arm through a rolling bearing. The push rod is sleeved with the push rod sliding block. One end of the supporting rod is hinged to the push rod sliding block, the other end of the supporting rod is fixedly connected with a supporting cross rod, and the supporting cross rod is rotationally installed on the large arm through a rolling bearing. Whether the large arm of the electric shovel is jacked up or not can be effectively monitored, certain counter force can be provided to prevent the large arm from being jacked up, and when the large arm is jacked up, an alarm device is triggered.
本发明提出了一种预警大臂被顶起式电铲及预警方法，该电铲包括：大臂和操作室，大臂铰接于操作室；耦合结构和缓冲预警结构，两者配合以用于监测大臂是否被顶起；其中：所述耦合结构包括：压力推杆，其一端固定于压力板，另一端与U型接头通过螺纹连接，U型接头的另一端通过销钉与推杆相铰接，推杆的另一端与大臂横杆连接，大臂横杆通过滚动轴承转动安装于大臂；推杆滑块套设于推杆；支撑杆，其一端与推杆滑块铰接，另一端与支撑横杆固定连接，支撑横杆通过滚动轴承转动安装于大臂。本发明可有效监测电铲大臂是否被顶起，并可以提供一定的反力阻碍大臂被顶起，当大臂被顶起时，触发报警装置。
