Description

一种带剥离功能的钎杆 所属技术领域
本发明属于破碎锤技术领域，尤其涉及一种带剥离功能的钎杆。
背景技术
目前破碎锤的钎杆只能撞击物体，使目标物破碎，在实际操作过程中，已经破碎的石块如果没有被及时清理掉会使钎杆无法准确瞄准破碎点，进行下一次打击；当目标物已被击碎时，再继续撞击会造成前体及主体螺丝松动及受损，严重的情况下还会损及工程机械体；如果在破碎作业进行时，企图将钎杆摇晃使用以清理破碎的石块，主体螺丝与钎杆将有破裂的可能。
本发明设计一种带剥离功能的钎杆解决如上问题。
发明内容
为解决现有技术中的上述缺陷，本发明公开一种带剥离功能的钎杆，它是采用以下技术方案来实现的。
一种带剥离功能的钎杆，其特征在于：它包括触发拨片、剥离片、剥离头、钎杆壳、钎杆顶盖、承力杆、承力杆复位弹簧、第一卡环、第二卡环、剥离储能弹簧、第三卡环、承力杆套、固定环、剥离推杆、卡孔、剥离安装孔、剥离片转轴、滑动键、固定孔、滑动槽、卡锁卡块、卡锁复位弹簧、推杆转动副、卡块限位件、卡块滑槽、拨片滑槽、限位件滑槽，其中钎杆壳的顶端安装有钎杆顶盖，钎杆壳的底端安装有剥离头，钎杆壳内部安装有承力杆；钎杆顶盖、承力杆复位弹簧、第一卡环、第二卡环、剥离储能弹簧、第三卡环从上至下依次安装在承力杆上，第一卡环和第二卡环固定在承力杆上，第三卡环安装在承力杆套顶端，承力杆复位弹簧安装在钎杆顶盖和第一卡环之间，剥离储能弹簧安装在第二卡环和第三卡环之间；承力杆的下端对称地安装有两个滑动键，承力杆套的内部对称地开有两个滑动槽，承力杆下端安装在承力杆套中，滑动键滑动于滑动槽中；承力杆套的底端安装有固定环，固定环周向均匀开有四个固定孔，四根完全相同的剥离推杆安装在固定环下方，对于任意一个剥离推杆，它的一端通过圆孔安装在固定环的固定孔孔壁上，另一端通过推杆转动副安装在剥离片内侧；剥离片有四个，四个剥离片为完全相同的五边形，对于任意一个剥离片，它通过剥离片转轴安装在剥离头上，剥离头上开有四个完全相同的剥离安装孔，剥离头的剥离安装孔底 端内侧开有四个卡孔，剥离片的内侧开有卡块滑槽，卡锁复位弹簧安装在卡块滑槽中，卡锁复位弹簧一端安装有卡锁卡块，卡锁卡块滑动于卡块滑槽中，两个卡块限位件对称地安装在卡锁卡块两侧，剥离片的内部开有两个限位件滑槽，卡块限位件滑动于限位件滑槽中，剥离片的外侧开有拨片滑槽，触发拨片安装在卡锁卡块上且从拨片滑槽中伸出。
本发明中，承力杆从钎杆顶盖中伸出一小段，撞击锤向下运动首先会撞击到钎杆中的承力杆，承力杆受到撞击力向下运动，之后撞击锤撞击到钎杆顶盖，整个钎杆向下运动；承力杆向下运动的过程中，承力杆复位弹簧被拉伸，剥离储能弹簧被压缩，承力杆在承力杆套中向下滑动，通过第三卡环、承力杆套、固定环、剥离推杆可以将剥离储能弹簧的推力传递到剥离片上，但由于剥离片上的卡锁卡块卡在卡孔中，剥离片即便受到剥离推杆的推力也无法转动打开；当钎杆撞击到物体时，剥离头上的触发拨片也会撞击到物体，触发拨片受到力的作用在拨片滑槽中向上滑动，同时与触发拨片相连接的卡锁卡块在卡块滑槽中向上滑动，卡锁复位弹簧被压缩，卡锁卡块从卡孔中移出，剥离片便在剥离推杆推力的作用下从剥离安装孔中弹出，此时剥离储能弹簧已将弹力释放，剥离推杆可绕固定环转动，此时四根剥离推杆张开的角度增大，已被破碎的石块便会被剥离片从破碎点剥离开。之后承力杆会在承力杆复位弹簧拉力的作用下回位，第二卡环向上运动，剥离储能弹簧被拉伸，第三卡环受到剥离储能弹簧的拉力作用带动承力杆套向上运动，四根剥离推杆张开的角度减小，将剥离片拉回到剥离片安装孔中，卡锁卡块重新回到卡孔中。
作为本技术的进一步改进，上述卡块滑槽、拨片滑槽、限位件滑槽是相通的。由于卡锁卡块、触发拨片、卡块限位件三者相连接，当触发拨片在拨片滑槽中向上滑动时，卡锁卡块在卡块滑槽中向上滑动，卡块限位件在限位件滑槽中向上滑动。
作为本技术的进一步改进，上述剥离推杆通过旋转副安转在固定孔上，承力杆上下运动时，剥离推杆可以在固定环上转动。剥离推杆向外转动，可将剥离片从剥离安装孔中推出，剥离片绕剥离片转轴向外转动；剥离推杆向里转动，可将剥离片拉回至剥离安装孔中，剥离片绕剥离片转轴向里转动。
作为本技术的进一步改进，上述剥离安装孔的形状为五边形和剥离片的形状 相同。
相对于传统的破碎锤技术，本发明中钎杆的剥离头上安装有剥离片，当钎杆向下打击物体时，触发拨片受到物体的阻力向上运动，剥离片便从剥离安装孔中弹出，将已破碎的物体从破碎点剥离；本发明对破碎锤中的钎杆进行了改造，通过剥离片可以使破碎锤在破碎物体的同时将已破碎的物体剥离，使破碎点具有较好的视野，具有较强的实用效果。

具体实施方式
如图1、11所示，它包括触发拨片24、剥离片25、剥离头26、钎杆壳27、钎杆顶盖28、承力杆29、承力杆复位弹簧30、第一卡环31、第二卡环32、剥离储能弹簧33、第三卡环34、承力杆套35、固定环36、剥离推杆37、卡孔38、剥离安装孔39、剥离片转轴40、滑动键41、固定孔42、滑动槽43、卡锁卡块44、卡锁复位弹簧45、推杆转动副46、卡块限位件47、卡块滑槽48、拨片滑槽49、限位件滑槽50，其中如图2、4所示，钎杆壳27的顶端安装有钎杆顶盖28，钎杆壳27的底端安装有剥离头26，钎杆壳27内部安装有承力杆29；如图3、5、10所示，钎杆顶盖28、承力杆复位弹簧30、第一卡环31、第二卡环32、剥离储能弹簧33、第三卡环34从上至下依次安装在承力杆29上，第一卡环31和第二卡环32固定在承力杆29上，如图10所示，第三卡环34安装在承力杆套35顶端，承力杆复位弹簧30安装在钎杆顶盖28和第一卡环31之间，剥离储能弹簧33安装在第二卡环32和第三卡环34之间；如图8、9所示，承力杆29的下端对称地安装有两个滑动键41，承力杆套35的内部对称地开有两个滑动槽43，承力杆29下端安装在承力杆套35中，滑动键41滑动于滑动槽43中；如图11、12所示，承力杆套35的底端安装有固定环36，固定环36周向均匀开有四个固定孔42，四根完全相同的剥离推杆37安装在固定环36下方，对于任意一个剥离推杆37，它的一端通过圆孔安装在固定环36的固定孔42孔壁上，另一端通过推杆转动副46安装在剥离片25内侧；剥离片25有四个，四个剥离片25为完全相同的五边形，对于任意一个剥离片25，如图7所示，它通过剥离片转轴40安装在剥离头26上，剥离头26上开有四个完全相同的剥离安装孔39，如图6所示，剥离头26的剥离安装孔39底端内侧开有四个卡孔38，如图13、14、15所示，剥离片25的内侧开有卡块滑槽48，卡锁复位弹簧45安装在卡块滑槽48中，卡锁复位弹簧45一端安装有卡锁卡块44，卡锁卡块44滑动于卡块滑槽48中，两个卡块限位件47对称地安装在卡锁卡块44两侧，剥离片25的内部开有两个限位件滑槽50，卡块限位件47滑动于限位件滑槽50中，剥离片25的外侧开有拨片滑槽49，触发拨片24安装在卡锁卡块44上且从拨片滑槽49中伸出。
本发明中，承力杆29从钎杆顶盖28中伸出一小段，撞击锤17向下运动首先会撞击到钎杆13中的承力杆29，承力杆29受到撞击力向下运动，之后撞击锤17撞击到钎杆顶盖28，整个钎杆13向下运动；承力杆29向下运动的过程中， 承力杆复位弹簧30被拉伸，剥离储能弹簧33被压缩，承力杆29在承力杆套35中向下滑动，通过第三卡环34、承力杆套35、固定环36、剥离推杆37可以将剥离储能弹簧33的推力传递到剥离片25上，但由于剥离片25上的卡锁卡块44卡在卡孔38中，剥离片25即便受到剥离推杆37的推力也无法转动打开；当钎杆13撞击到物体时，剥离头26上的触发拨片24也会撞击到物体，触发拨片24受到力的作用在拨片滑槽49中向上滑动，同时与触发拨片24相连接的卡锁卡块44在卡块滑槽48中向上滑动，卡锁复位弹簧45被压缩，卡锁卡块44从卡孔38中移出，剥离片25便在剥离推杆37推力的作用下从剥离安装孔39中弹出，此时剥离储能弹簧33已将弹力释放，剥离推杆37可绕固定环36转动，此时四根剥离推杆37张开的角度增大，已被破碎的石块便会被剥离片25从破碎点剥离开。之后承力杆29会在承力杆复位弹簧30拉力的作用下回位，第二卡环32向上运动，剥离储能弹簧33被拉伸，第三卡环34受到剥离储能弹簧33的拉力作用带动承力杆套35向上运动，四根剥离推杆37张开的角度减小，将剥离片25拉回到剥离片安装孔39中，卡锁卡块44重新回到卡孔38中。
上述卡块滑槽48、拨片滑槽49、限位件滑槽50是相通的。由于卡锁卡块44、触发拨片24、卡块限位件47三者相连接，当触发拨片24在拨片滑槽49中向上滑动时，卡锁卡块44在卡块滑槽48中向上滑动，卡块限位件47在限位件滑槽50中向上滑动。
上述剥离推杆37通过旋转副安转在固定孔42上，承力杆29上下运动时，剥离推杆37可以在固定环36上转动。剥离推杆37向外转动，可将剥离片25从剥离安装孔39中推出，剥离片25绕剥离片转轴40向外转动；剥离推杆37向里转动，可将剥离片25拉回至剥离安装孔39中，剥离片25绕剥离片转轴40向里转动。
上述剥离安装孔39的形状为五边形和剥离片25的形状相同。
综上所述，本发明中钎杆的剥离头上安装有剥离片，当钎杆向下打击物体时，触发拨片受到物体的阻力向上运动，剥离片便从剥离安装孔中弹出，将已破碎的物体从破碎点剥离；本发明对破碎锤中的钎杆进行了改造，通过剥离片可以使破碎锤在破碎物体的同时将已破碎的物体剥离，使破碎点具有较好的视野，具有较强的实用效果。
