Description

Special grab bucket crane is snatched to coke of intelligence Technical Field The utility model relates to the field of grab cranes, in particular to an intelligent grab crane special for coke grabbing. Background The grab bucket crane refers to a hoisting machine provided with a grab bucket, and is widely used for loading various bulk cargos, logs, minerals, cokes, sand stones, earthwork and the like in ports, wharfs, station yards, mines and the like. The grab bucket crane is an automatic fetching machine, and the grabbing and unloading actions of the grab bucket crane are controlled by a ship unloader driver without auxiliary personnel, so that the heavy labor of workers is avoided, the auxiliary working time is saved, and the loading and unloading efficiency is greatly improved. Grab cranes are generally classified into bridge type grab cranes, portal type grab cranes, folding arm type grab cranes, and what is commonly known as a folding arm type grab crane. Through the lubrication assembly arranged, the transmission part works, so that the connecting part can move downwards, the liquid storage mechanism can be driven to operate along with the downward movement of the connecting part, a certain amount of lubricating oil is extruded into the liquid outlet mechanism, the transmission assembly is controlled to operate, the steel cable on the winding assembly is contracted or released, the steel cable is further infected with the lubricating oil, continuous operation of personnel is not needed for lubrication, and the labor intensity of the personnel is reduced. However, the above device still has certain drawbacks, for example, coke processing enterprises usually adopt a grab crane to turn coke, and it is known that the lower end of the grab on the existing grab crane is narrower (or more pointed), so that a plurality of grabs can be folded to transfer coke, but due to the arrangement, when the grabs grab grabs coke, the amount of coke grabs once is smaller, and the main reason is that when the grabs coke, the grabs grab grabs coke first needs to be folded, and when the grabs grab grabs coke is folded, the lower end of the grab is narrower, and the coke is more powdery, so that the coke cannot be driven to enter the middle of the plurality of grabs, or a large amount of coke cannot be accumulated, so that the single grabbing amount is smaller. Therefore, it is necessary to invent an intelligent grab crane special for coke grabbing to solve the above problems.
