重/轻型液压扩张钳操作规范和注意事项 | 2011-3-30 11:38:00

重/轻型液压扩张钳操作规范和注意事项

基本功能与设备构成：用于扩张、抬升重型构件。由液压泵、液压胶管、扩张钳、扩张钳头、强力扩张钳头组成。
操作步骤
⑴ 连接液压泵、液压胶管、扩张钳；
⑵ 启动液压泵，打开液压油阀门；
⑶ 操作手柄上的“←→”（扩张）或“→←”（闭合）；
⑷ 牵拉时，将钳头完全张开，更换专用钳头，连接牵引链，固定被牵引物体，闭合扩张钳，进行牵拉；
⑸ 撤收时，闭合扩张钳，关闭液压阀、液压泵，将液压管与液压泵、扩张钳进行分解。
常见故障排除
扩张钳与液压泵、液压胶管连接不上时，应检查液压泵、液压胶管和工具本身是否存有压力，快速接头是否损坏。用液压阀放掉存留的压力，更换损坏的快速接头。
注意事项
⑴ 扩张时要使两个钳头始终保持垂直，扩张点受力要均衡。
⑵ 当扩张到最大行程时，不得对扩张器实施压力传输。
⑶ 在液压泵处于工作状态时，禁止进行分解作业。
⑷ 最大扩张力作用点在扩张臂的根部。
⑸ 最大扩张距离为833mm。
