Mounting method of locking device for platform type crushed stone laying and leveling ship

Abstract

The invention discloses a mounting method of a locking device for a platform type crushed stone laying and leveling ship, and relates to the technical field of ocean engineering and shipbuilding. Parts of the locking devices are mounted in steps, and a mounting process for the parts of the locking device comprises the following steps: firstly, hoisting a worm and gear jack; secondly, after the worm and gear jack is mounted in place, mounting a wedge block support base and a regulating wedge block; thirdly, hoisting a return oil cylinder into a lifting framework in advance, and connecting one end of the return oil cylinder to an oil cylinder support base on an enclosure well structure; fourthly, hoisting a tooth-shaped block, connecting the tooth-shaped block to a pin roll at the other endof the return oil cylinder, and regulating a gap between an insertion pin mechanism support base and the tooth-shaped block; and finally, mounting an insertion pin mechanism, and regulating a gap between a baffle block on the tooth-shaped block and an insertion pin on the insertion pin mechanism according to design requirements. The mounting method has the advantages of being friendly in construction environment, convenient in mounting, capable of improving operation efficiency and normalizing production process, and being safe and reliable.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and shipbuilding, in particular to a method for installing a locking device for a platform-type gravel-laying leveling ship. Background technique [0002] The lifting system of the platform gravel laying and leveling ship is a rack and pinion type. The ship has 4 legs in total, located at the four corners of the platform. Each leg has 12 sets of symmetrically installed lifting devices, and a set of locking mechanism is set at the same time. Used to lock the leg rack. The locking mechanism adopts a domestic self-developed device. The upper and lower wedges are pushed by two sets of vertical worms to fix the locking rack. The worms are hydraulically driven and have the function of dynamic load transfer, which can buffer the impact caused by locking on the leg rack. greater vibration and shock. As an important part of the platform, the locking device is the key to ensure the safety and ...

AI Technical Summary

Problems solved by technology

[0004] 1) The locking device can only be installed after the berth of the lifting frame is closed, and the installation position inside the lifting frame is narrow;

[0005] 2) The installation position of the locking device is located at the lower part of the structural partition and the installation panel of the jack, limited by the space position, it is impossible to use vertical lifting method for alignment installation;

[0006] 3) The position gap between the support of the latch mechanism and the toothed block, the stopper on the toothed block and the latch must meet the requirements of the design drawings, and the installation is difficult
