Stall self-locking and jerking prevention device of deep-digging excavator
The invention relates to the technical field of excavators, and discloses a stall self-locking and jerking prevention device of a deep-digging excavator. The device comprises a mounting component, anda mounting groove is formed in the mounting component; a first spring mechanism is movably installed in the mounting groove, and the upper end of the first spring mechanism is fixedly connected witha push plate; the upper side of the push plate is fixedly provided with a metal part, and an ejector rod is movably installed in the first spring mechanism; and the upper end of the ejector rod is fixedly connected with the lower side of the push plate. In the fast falling process of an excavator bucket, an electrical metal sheet is powered on, so that an electromagnet is energized and generates huge magnetism; under the effect of centrifugal force, the electromagnet is expanded outwards, and a magnetic ring is expanded outwards simultaneously, and attached to the inner side of the mounting component; since an anti-skid gasket is arranged on the outer side of the magnetic ring, the magnetic ring generates large friction force, so that the device is decelerated through friction to stop; andthus, the effect of reducing the jerking sense during self-locking is achieved.
本发明涉及挖掘机技术领域，且公开了一种深挖挖掘机的失速自锁且防顿挫的装置，包括安装部件，所述安装部件的内部开设有安装槽，所述安装槽的内部活动安装有第一弹簧机构，所述第一弹簧机构的上端固定连接有推板，所述推板的上侧固定安装有金属件，所述第一弹簧机构的内部活动安装有顶杆，所述顶杆的上端固定连接在推板的下侧。通过挖斗快速下落的过程中，电性金属片进行通电，使电磁铁过电，产生极大的磁性，在离心力的作用下使电磁铁向外侧扩展，磁圈同时向外扩展，贴于安装部件内侧，由于磁圈外侧设置有防滑圈套，使其产生极大的摩擦力，从而使装置通过摩擦减速直至停止，从而达到了自锁时减少顿挫感的效果。
