Embodiment Construction

[0031] In order to better understand the above-mentioned technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0032] combine Figure 6 to Figure 9 As shown, a column flange processing method of a shore container crane provided by the present invention comprises the following steps:

[0033] S1. The upper and lower sections 5 and 6 of the column are made separately, and the two flange plates 7 are blanked and scraped, and then drilled in pairs, and fixed with bolts to form a flange assembly;

[0034] S2. The upper and lower sections 5 and 6 of the column are assembled with the flange components and passed the inspection. Three scoring plates 8 are respectively installed on the webs on the upper and lower sides of the flange plate 7. The marking plates 8 need to be Arranged at a position convenient for measurement, wherein two scribed plates 8 are arranged...

Abstract

The invention discloses a machining method for a stand column flange of a quayside container crane, comprising: symmetrically leading out three reference points on webs on the upper side and the lower side of the flange by taking a binding surface before the flange is dismounted as a reference, so as to determine two completely parallel reference surfaces, and readjusting the states of upper and lower columns after the upper and lower columns are dismounted; and directly processing a flange binding surface by using a reference surface led out from the web plate. The method can reduce the difficulty of marking the thickness allowance of the flange.

Description

technical field [0001] The invention relates to a method for installing a steel structure of a crane, in particular to a method for processing a column flange of a shoreside container crane. Background technique [0002] With the continuous development of port trade, shore-to-shore container cranes are showing a trend of large-scale development year by year. In order not to affect the normal operation of the terminal, many users require that the cranes be installed and debugged by the manufacturer as a whole and shipped as a whole. During the process, sometimes the height of bridges and other buildings is limited, and it is necessary to reduce the height of the crane during transportation. For this reason, a shore-to-shore container crane that can reduce the height during transportation is designed. The shoreside container crane is designed with a flange plate in the middle of the door frame column, such as Figure 1 to Figure 3 As shown, the flange plate 1 is fastened with ...
