Hydraulic double-lock quick-change device for quickly switching working accessories of excavator
The hydraulic double-lock quick-change device comprises a quick-change main body, a main hook and a rear lock hook, the quick-change main body comprises two side plates, two reinforcing plates and a supporting frame, a hydraulic oil cylinder is arranged on the inner side of the supporting frame, a piston rod of the hydraulic oil cylinder is located in the horizontal direction, and a push-pull block is arranged at the end of the piston rod; a push rod is arranged on the other side of the push-pull block; the main hook is arranged at the front ends of the two side plates and the two reinforcing plates, and a front locking plate is arranged in the middle of the main hook close to the reinforcing plate on one side; the rear lock hook comprises two columnar structures, two through holes are formed in the supporting frame in the horizontal direction, the tails of the two columnar structures penetrate out of the two through holes and can slide in the two through holes respectively, the middle positions of the columnar structures are fixed to the push-pull block, and the front ends of the columnar structures penetrate into the locking mechanism. The front safety lock and the rear safety lock are designed, double safety guarantee is achieved, and safety accidents caused by accidental falling of the work accessory due to failure of a hydraulic system can be prevented.
本发明公开了一种用于挖掘机快速切换工作属具的液压双锁快换装置，包括快换主体、主钩、后锁钩，快换主体包括两个侧板、两个加强板和一个支撑架，支撑架内侧设置有液压油缸，液压油缸的活塞杆处于水平方向，其端部设置有一个推拉块，推拉块另一侧设置有推杆；主钩设置在两个侧板及两个加强板前端，主钩中间靠一侧加强板处设置有前锁板；后锁钩包括两个柱状结构，支撑架在水平方向开设有两个通孔，两个柱状结构尾部从两个通孔穿出，并能够分别在两个通孔内滑动，柱状结构的中间位置固定于推拉块上，柱状结构的前端位置穿入锁紧机构。本发明设计有前后安全锁，具备双重安全保障，能够防止因液压系统的失效使工作属具意外脱落引起的安全事故。
