具体实施方式
如图1所示,单侧打击破碎锤结构为:连接板2上分别设有两个轴孔4,连接板2前端固定连接法兰盘5,法兰盘5螺栓连接多孔缸体31,多孔缸体31分别设有两个通孔,一个通孔内安有活塞杆11,活塞杆11下半部分与通孔上端安有轴套一3,通孔中间分别安有数个销轴33,活塞杆11底端安有轴套二32;多孔缸体31上端与活塞杆11下半部分***安有限位器25,限位器25下端设有限位器减震胶26,限位器减震胶26下端设有限位器调整油缸1,活塞杆11下半部分与油缸桶9之间安有油缸密封导向套一7,油缸密封导向套一7上设有氮气室8,油缸密封导向套一7外端设有充气阀6,活塞杆11外部分设有油缸桶9,油缸桶9通过减震胶套10连接锤铁固定套筒22,锤铁固定套筒22顶部与油缸桶9中间设有碟型弹簧21,活塞杆11上端设有中空油缸杆15,油缸桶9上端与中空油缸杆15之间安有油缸密封导向套二14,油缸密封导向套二14下端设有液压油室12,中空油缸杆15下端设有油道孔13,中空油缸杆15上端设有通孔连接油道17;中空油缸杆15顶端通过缸杆帽固定螺栓19固定连接缸杆帽18,缸杆帽18底端与中空油缸杆15顶端之间设有油封20,缸杆帽18单侧端安有电控换向阀16,电控换向阀16连接油道17;锤铁固定套筒22下端安装锤铁23,锤铁23滑动安装在锤铁导向套24内;多孔缸体31另一个通孔内安有钎杆30,多孔缸体31上端安有锤铁导向套24,多孔缸体31下端安有钎杆导向套29通过销轴一28固定,钎杆30中间由扁销铁27滑动连接。
单侧打击破碎锤的中间是液压油缸,液压油缸外部是减震胶,减震胶带动外面固定套筒,固定套筒带动锤铁上升和下落,液压部分和打击部分采用并联结构,打击锤铁和钎杆为外露式串联结构。
单侧打击破碎锤具体运行原理如下:
1、向上运动说明:由挖掘机油泵提供的高压油,通过电控换向阀16的进油口(此时阀杆处在进油位置)进入油道17,油道17中的高压油,通过油道孔13进入液压油室12,高压油推动油缸桶9和锤铁固定套筒22和锤铁23向上移动至设定距离,同时氮气室8内的氮气被压缩。
2、向下运动说明:油缸桶9移动至设定距离后,电控换向阀16进油口关闭并同时打开出油口,氮气室8内压缩后的氮气反向推动油缸桶9向下移动,油缸桶9同时带动锤铁固定套筒22和锤铁23向下打击钎杆30,同时活塞杆11挤压液压油室12内的高压油,高压油通过油道孔13经过电控换向阀16的排油口进入挖掘机回油***。以上动作循环往复。
3、当锤铁23打击钎杆后仍没有停止时,会打击在限位器25顶部,限位器25下部限位器减震胶26将被压缩吸收部分冲击力,避免锤铁23对多孔缸体31的冲击。
4、以上运动不断重复。
