Ship block assembly quick alignment device and method

Abstract

The invention discloses a ship block assembly quick alignment device and a ship block assembly quick alignment method, can be used for adjusting ship block positions and postures in states such as shipway block assembly, general block assembly, shipway assembly and the like, and belongs to the technical field of ship block assembly devices. Aiming at the characteristics of large scale, large tonnage, complicated appearance, low possibility of being moved and accurately aligned and the like of the shipway block assembly, the ship block assembly quick alignment device is designed and developed, and can realize six degree-of-freedom axial shifting and rotating motion of the ship blocks on a universal adjustable platform. The automatic alignment system with accurate alignment function can quickly free cranes, save manpower, improve the quality and efficiency of block folding, and facilitate improving ship building accuracy and shortening construction period.

Description

technical field [0001] The invention relates to a fast alignment device for segmented hull assembly and a method thereof, which can be used to adjust the segmented position and attitude of the hull in the states of segmental assembly, segmental assembly, and berth assembly, and belongs to the technical field of hull segmental assembly devices . Background technique With the application of slipway assembly technology without margin, the efficiency and quality of slipway assembly have been greatly improved. At present, the segmental closing method mainly follows the two traditional methods of assembly workers and crane drivers cooperating with each other for hoisting, positioning and installation, and using a slipway trolley to close up. There are low utilization rate of the crane, complicated operation, poor alignment accuracy, long time, and danger. advanced questions. The segmental assembly, segmental final assembly, and berth assembly and positioning of the hull segme...

Problems solved by technology

At present, the segmental closing method mainly follows the two traditional methods of assembly workers and crane drivers cooperating with each other for hoisting, positioning and installation, and using a slipway trolley to close up. There are low utilization rate of the crane, complicated operation, poor alignment accuracy, long time, and danger. advanced questions

The segmental assembly, segmental final assembly, and berth assembly and positioning of the hull segment are still in the state of manual operation. A common method is that the assembler and the crane driver cooperate with each other to lift, position and install. The supporting pier below the segment is non-adjustable. For ordinary marine piers, the movement of the section position and the adjustment of the posture all depend on the crane and manpower. During this period, the crane cannot be used for other purposes, and the accuracy is not easy to control during the hoisting and positioning process using the crane. There are large gaps in the section welds. The stress affects the construction quality, and there are problems such as low crane utilization rate, poor alignment accuracy, long construction period, and high risk

At present, there are also vertically adjustable piers in shipyards. This pier has a jacking cylinder, which can adjust the sections in the height direction, but cannot realize horizontal and left-right adjustments. In order to shelve the sections, they must be frequently transported and stacked heavily. pier wood

The number of these manual operations is large, the weight is heavy, and the distance between the bottom of the ship and the surface of the berth is only 1.2m-1.8m. The operation is often carried out under the condition that people cannot stand upright, with low work efficiency, many working hours and heavy labor.
