The invention discloses a double-safety quick automatic connector for an excavator and belongs to the technical field of ancillary equipment for excavators. The double-safety quick automatic connector is technically characterized by comprising a main hook body, wherein a front positioning gap and a rear positioning gap are formed in the edge of the main hook body; a front hook and a rear hook are correspondingly hinged to the positions, at the side edges of the front positioning gap and the rear positioning gap, on the main hook body respectively; a hydraulic oil cylinder is hinged to the main hook body and is connected with a hydraulic station; the free end of a piston rod of the hydraulic oil cylinder is hinged to the rear hook; the front hook is hinged to a side link; two ends of a crank connecting rod are hinged to the middle part of the side link and the main hook body respectively; the front hook, the side link and the crank connecting rod are matched to form a four-connecting-rod crank rocker mechanism; a locking device is connected between the side link and the main hook body. The invention aims to provide the double-safety quick automatic connector for the excavator, which is convenient to use and good in effect. The double-safety quick automatic connector is used for an excavator replacing operation tool.
Description
technical field [0001] The invention relates to a double safety quick automatic connector for an excavator, more specifically, especially to a double safety quick automatic connector for an excavator to replace working tools. Background technique [0002] With the expansion of the scope of excavator machinery, excavator tools are becoming more and more diversified. The excavator quick connector can realize the rapid replacement of work equipment, save working time and improve work efficiency. For the sake of safety, at present, the quick connectors of excavators above 10 tons generally use hydraulic cylinders with hydraulic locks, and at the same time, artificially place safety pins. [0003] However, there is a certain potential safety hazard in the operation of manually placing the safety pin on the work tool. In the case that the connector and the work tool are not completely locked, if the driver mistakenly thinks that it has been locked, and then manually places the sa...
