Hydraulic quick coupler for excavator
The invention discloses a hydraulic quick coupler for an excavator, and particularly relates to the technical field of excavator accessories, which comprises a coupler body and a movable mechanism, the coupler body comprises a connecting frame, a pin shaft, a locking device, a pivot pin, a hydraulic cylinder, a hinged support pin, a locking pin and a safety pin; the two pin shafts are connected with the connecting frame through a movable mechanism; the locking device is connected with the connecting frame through a pivot pin and is used for fixing the working device; the hydraulic cylinder is rotationally connected with the connecting frame through a hinged support pin, and the piston end of the hydraulic cylinder is connected with the locking device through a locking pin. The hydraulic control one-way valve is installed on the hydraulic cylinder and used for locking the hydraulic cylinder. The electromagnetic reversing valve is used for controlling the hydraulic cylinder to be disengaged and clamped. The safety pin is arranged on the connecting frame in a penetrating mode and makes contact with the locking device. The device is simple in structure, convenient to operate, safe and reliable, the efficiency of replacing the working device of the excavator can be remarkably improved, and the device has wide practical value and market prospects.
