Hydraulic quick-change connector for excavator
The invention relates to the technical field of engineering special vehicles, and discloses a hydraulic quick-change connector for an excavator. When a piston sleeve is in an initial position state, a liquid guide pipe is in a blocked and non-circulating state, so that the liquid guide pipe penetrates through a hydraulic bin II and a rotating bin and is fixedly connected with one end of an oil injection port I; when a locking groove I is in a locking state, hydraulic oil enters a hydraulic bin I through a liquid guide pipe and an oil injection port I, and at the moment, the pressure intensity of liquid in the hydraulic bin I is increased, so that a limiting plate is pushed to extend out of the interior of the hydraulic bin I. The limiting plate is matched with a locking groove II when the locking groove I is in the locking state; and when hydraulic failure occurs to the device, one side of the locking plate cannot be reset due to the fact that the limiting plate abuts against the locking plate, it is guaranteed that an accessory connected with the device cannot fall off at the moment, and therefore the safety limiting effect is achieved. And safety accidents are avoided, and the safety performance of the device is improved.
本发明涉及工程特种车辆技术领域，且公开了一种挖掘机用液压式快换连接器，通过活塞套筒处于初始位置状态时导液管处于阻塞无法流通的状态，使得导液管贯穿液压仓Ⅱ和转动仓并与注油口Ⅰ的一端固定连接，使得液压油通过导液管和注油口Ⅰ进入到液压仓Ⅰ的内部，此时液压仓Ⅰ内部的液体压强升高，从而推动限位板从液压仓Ⅰ的内部伸出，由于锁定槽Ⅰ处于锁定状态时限位板与锁定槽Ⅱ相配合，使得此时限位板伸出后会插入到锁定槽Ⅱ的内部，从而将锁定板的一侧抵住，达到安全限位的效果，当该装置出现液压失效时锁定板的一侧由于被限位板抵住从而无法进行复位，保证此时该装置所连接的属具不会发生脱落，避免了安全事故的发生，提高了该装置的安全性能。
