Abstract

The invention discloses an oil cylinder luffing crane tower body and a processing method thereof, and belongs to the field of crane tower body processing. The tower body comprises a tower body shell; and one end of the tower body shell is connected with a top cover, and the other end of the tower body shell is connected to a tower body large baseplate, which is provided with a rotary mounting surface and a plurality of through holes. The tower body also comprises an oil tank chamber shell on the top of the top cover and a side plate. The processing method comprises the steps of: respectively welding the oil tank chamber shell, the side plate, the top cover and a lifting mechanism installation support together; welding the molded tower body shell and the tower body large baseplate together; processing the tower body large baseplate plane; and conducting closure welding. The tower body provided by the invention is convenient for processing and has the advantages of small volume and small impact on driver's sight line. The invention adopts a split type processing method of tower body, and can utilize existing ordinary drill and tools, so as to shorten the processing cycle, reduce processing costs, and reduce the processing difficulty.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an oil cylinder luffing crane tower body and a processing method thereof. Background technique [0002] In construction and offshore platforms, cranes are a common large-scale mechanical equipment. Cranes can usually be divided into cylinder luffing series and wire rope luffing series. At present, cylinder luffing cranes are mostly used in automobiles, and their weight is small. [0003] The cylinder luffing crane mainly includes the tower body, the lifting mechanism, the slewing mechanism and the luffing mechanism. Among them, the tower body includes a large bottom plate of the tower body and a main body of the tower body fixed on the large bottom plate of the tower body. The large bottom plate of the tower body is provided with a mounting hole of a slewing mechanism and a mounting surface of a slewing ring, etc. The main body of the tower body is a cylinder The structure of the combinat...
