A control device and a control method for the installation of a ship's long stern shaft through a shaft

Abstract

The invention discloses control equipment and method used for shaft-penetrating mounting of a ship long stern shaft. The control equipment comprises a clamping limiting signal lamp used for indicatingthe working state of a fixture assembly on a supporting trolley, an up-down adjusting button, a left-right adjusting button, a position detecting switch, a position detecting signal lamp, a stern shaft frame limiting signal lamp, a stern shaft pipe limiting signal lamp and a stern shaft limiting signal lamp, wherein the up-down adjusting button and the left-right adjusting button are used for adjusting the positions of jacks of the supporting trolley and an idler wheel trolley vertically and horizontally in a pointing control mode; the position detecting switch is used for detecting the positions of the long stern shaft on the supporting trolley and the idler wheel trolley; the position detecting signal lamp is used for indicating the position states of the long stern shaft on the supporting trolley and the idler wheel trolley; the stern shaft frame limiting signal lamp, the stern shaft pipe limiting signal lamp and the stern shaft limiting signal lamp are connected to a stern shaft frame proximity switch, a stern shaft pipe proximity switch and a stern shaft position detecting switch correspondingly and indicate the states of the long stern shaft at the set positions on a stern shaft frame and a stern shaft pipe. According to the control equipment and method, the automation degree and the shaft-penetrating efficiency of shaft-penetrating operation of the long stern shaft areimproved, the operating labor intensity of operators is reduced, and the production cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of ship assembly, and in particular to a control device and a control method for installing a long stern shaft of a ship through a shaft. Background technique [0002] The large ships built by the company need to carry out shaft passing operation on the long stern shaft of the ship. The long stern shaft of the ship generally reaches more than 50 tons, even more than 80 tons, and the length is more than 18 meters. The long stern shaft presents great difficulty in the threading operation with such a small clearance. Faced with such delicate and difficult shaft threading work, the existing method is generally to use chain hoists purely for the entire operation, requiring more than 20 people to assist at the same time and spending 24 hours a day and night to complete a shaft threading; or sometimes use a heavy flatbed truck Auxiliary chain hoists to thread the shaft, although the effi...
