Abstract

The invention provides a connecting device and an excavator, and relates to the technical field of engineering machinery. The connecting device comprises a rack, an action mechanism, a main hook, a lock hook and a lock catch piece; the main hook is fixedly connected to the rack; the action mechanism comprises a driving piece and a linkage piece; the driving piece and the lock hook are rotationallyconnected with the rack separately; the driving piece is rotationally connected to the lock hook through the linkage piece; the driving piece drives the linkage piece to drive the lock hook to rotatein the direction away from or close to the main hook to be matched with the main hook to be connected with or separated from the accessory; and the lock catch piece is used for abutting against the action mechanism to lock the action mechanism when the lock hook is in the state of being connected with the accessory. According to the invention, the lock hook in the connecting device is matched with the main hook and the accessory in a moving mode to be detachably connected, and the accessory can be rapidly disassembled by operating the lock catch piece and the driving piece so that the accessory replacement difficulty can be reduced, and meanwhile the accessory replacement efficiency can be improved. The mechanical connection mode can effectively simplify a hydraulic control structure in the prior art, and the problem that a hydraulic system is complex in arrangement is avoided.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a connection device and an excavator. Background technique [0002] With the rapid economic growth and the vigorous development of infrastructure construction, construction machinery, as an indispensable role in modern engineering construction, plays an important role in improving construction efficiency. Excavator is a kind of construction machinery, which usually consists of working device, slewing platform and walking device. Among them, the working device is a device that directly completes the excavation task. The walking device is used to drive the whole machine to walk and move the position. The slewing device is located between the traveling device and the working device, and is used to drive the working device to rotate on the horizontal plane. Due to the variability of construction conditions, in order to adapt to different working conditions, the worki...
