AI Technical Summary
Technical Problem
[0003]现有的液压打桩锤存在以下几个缺点：1、打桩锤工作时的高频振动会使锤壳上布置的线缆由于缺乏端部固定，随锤壳振动，导致线缆被拉伸、绝缘层被磨损，影响其正常使用；2、打桩过程中，钢丝绳与锤壳上的法兰、法兰螺栓直接接触并且相互摩擦，造成钢丝绳表面磨损，导致钢丝绳承载能力和使用寿命降低；3、锤壳顶部会设置卸扣，用于连接桩身和转移冲击力，而卸扣在施工过程中会与锤壳发生机械碰撞出现振动，导致锤壳出现凹坑、磨损等情况，甚至卸扣与锤壳连接处会出现破损，存在安全隐患；4、为适应不同桩径的施工需求，用户需购买最大桩径的打桩锤，当需要作业于较小直接钢桩时，在桩套内焊接筋板以改变桩套内径，反复拆装焊接会导致桩套性能下降、疲劳强度降低
Benefits of technology
[0006]具有上述特征的本实用新型：线缆的悬空端通过缓冲装置固定在安装板上，避免线缆随锤壳振动而摆动，从而避免线缆被反复拉伸；当锤壳高频振动时，上、下缓冲垫能够从两个方向吸收振动，为线缆提供双向减震功能，延长线缆的使用寿命。
