Scissor aerial work platform with quick change locking mechanism and its working tool quick change method

Abstract

The application provides a scissor-type aerial work device with a quick-change locking mechanism and a quick-change method of work accessories of the aerial work device. The device comprises a chassis, a lifting mechanism, a connecting frame, work accessories and a quick-change locking mechanism. The lifting mechanism connects the chassis and the connecting frame to drive the connecting frame to lift. The quick-change locking mechanism is arranged between the connecting frame and the work accessories and comprises a first locking structure for docking and positioning and bearing main load rigidity locking and a second locking structure for realizing auxiliary locking. The lifting mechanism adopts a scissor-type arm frame. The arm frame, the chassis and the connecting frame are hinged at one end and are in sliding fit at one end. The quick-change method realizes automatic double locking by positioning and lowering the work accessories. The accessories can be quickly replaced by unlocking in sequence. The application can realize quick disassembly and assembly of the accessories without special tools. The double locking structure improves the connection safety and stability and can be adapted to various work accessories. The application effectively solves the problems of traditional equipment, such as complicated accessory replacement, single function and low work efficiency, and reduces the use and operation cost of the equipment.
