Abstract

The invention provides a cutting and welding device used for replacement of a cutting edge blade of a grab bucket of a ship unloader. The cutting and welding device comprises a rail, manual lifting portals and movable cutting and welding equipment. The manual lifting portals comprise portal bodies, lead screws and nuts, the lead screws extend in the Z-axis direction and penetrate through the topsof the portal bodies, handles are arranged at the top ends of the lead screws, and the ends of the rail are connected with the nuts through mounting portions. The movable cutting and welding equipmentcomprises a rack arranged on the rail, a Y-axis walking motor mounted on the rack and cutting and welding equipment, the Y-axis walking motor drives the rack to move along the rail, an X-axis walkingmotor, a Z-axis walking motor and a rotating motor which are connected sequentially are further arranged on the rack, and an output shaft of the rotating motor is connected with the cutting and welding equipment. The cutting and welding device has the beneficial effects that heat source moving in the cutting and welding processes of the cutting edge plate is completed by a mechanical device, cutting and welding angles are adjusted through cooperation of operation personnel, and linear parts can be cut and welded rapidly and stably. The whole work process is simple and convenient, the construction period is short, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment maintenance, in particular to a cutting and welding device for replacing a grab edge plate of a ship unloader and a method for using the same. Background technique [0002] The large-scale bridge grab ship unloader is a large-scale hoisting machinery widely used in wharves, responsible for lifting operations on water, and its grab is an important part of the ship unloader. Due to the harsh environment of the raw material wharf and the long-term wear of the grab, the maintenance cycle of the grab is relatively short, and it needs to be disassembled and repaired after the usage time expires. When repairing the grab bucket, it is necessary to disassemble the grab bucket as a whole, and replace the 6 cutting edge plates (plate thickness 50mm) of the grab bucket. The on-site construction of the project has the following problems: 1) Many welders are invested in the maintenance of the grab...
