Accessory anti-falling device of mechanical-electrical-hydraulic quick-change system
The invention belongs to the technical field of engineering machinery, and particularly relates to a mechanical-electrical-hydraulic quick-change system accessory anti-disengaging device which comprises an upper coupling piece and a lower coupling piece, and one end of the upper coupling piece and one end of the lower coupling piece are provided with anti-disengaging structures which are connected in a matched mode. The other end of the upper coupling piece and the other end of the lower coupling piece are provided with a pin shaft with a telescopic spring and a clamping groove which are mutually matched and connected; a rotatable locking mechanism is arranged at the matching position of the pin shaft with the telescopic spring and the clamping groove, the locking mechanism has a first rotating direction and a second rotating direction, and the locking mechanism comprises a disassembling face matched with the first rotating direction and a locking face matched with the second rotating direction. According to the quick-change device, locking and falling prevention are not completed and removed at the same time any more, the participation degree of personnel in the accessory switching process of the quick-change device is greatly reduced, an operator only needs to rotate a pull rod to complete steering and then can leave, the leaving time of a working site is provided for workers, and safety is improved; the switching time is reduced, and the efficiency is improved.
本申请属于工程机械技术领域，具体涉及一种机电液快换系统属具防脱装置，包括上耦合件和下耦合件，上耦合件的一端和下耦合件的一端具有相互配合连接的防松脱结构，上耦合件的另一端和下耦合件的另一端具有相互配合连接的带伸缩弹簧的销轴与卡槽；在带伸缩弹簧的销轴与卡槽的配合处设有可旋转的锁紧机构，锁紧机构具有第一旋转方向和第二旋转方向，锁紧机构包括与第一旋转方向匹配的拆卸面和与第二旋转方向匹配的锁紧面。本申请使锁死与防脱落不再是同时完成和解除，大大降低了快换装置在切换属具过程中人员的参与度，操作人员只需要转动拉杆完成转向即可离场，为工人提供作业现场的离场时间，提高了安全性；减少切换时间，提高效率。
