Problems solved by technology

[0003] At present, in the shipbuilding industry, the margin marking work of the steel structure of the hull is still done manually, which takes up a lot of berth or dock cycle, and wastes a lot of effective working time of the crane.
Manual scribing has low efficiency, poor precision, high labor intensity, and is also restricted by the influence of the natural environment, and the operation is highly dangerous

Embodiment Construction

[0026] The structure of the present invention will be further described below with reference to the accompanying drawings.

[0027] Gantry hull section marking machine (such as figure 1 , 2 , Shown in 3) is made up of marking mechanism and gantry frame, and marking mechanism is installed on the upper beam 7 of gantry. The scribing mechanism mainly includes a trolley 10 and a multi-degree-of-freedom scribing arm. The gantry includes track 1 and track wheel 4, horizontal beams and column groups. The main function of the marking mechanism is to provide high-precision multi-degree-of-freedom movement and positioning; the main function of the gantry is to support the trolley and the marking arm, and carry control equipment.

[0028] 1. Tracks and wheels

[0029] The track 1 is laid horizontally and parallel, and is firmly connected with the ground concrete. The upper surface of the track 1 in the trench 2 is flush with the ground, which facilitates the segmental displacement of...

Abstract

The invention discloses a gantry type hull sectional drawing machine and belongs to the technical field of shipbuilding and oceanography engineering. The hull sectional drawing machine is composed of a drawing mechanism and a gantry. The drawing machine mounted on the gantry comprises a trolley and a multi-freedom-degree drawing arm; and the gantry is provided with a travelling mechanism on rails. The gantry supports the trolley and the drawing arm; the drawing mechanism which provides high-accuracy multi-freedom-degree movement and locating is a fundamental structure of the drawing machine and is composed of a plumbing arm, swing arms, omni-directional mechanisms, Z-shaped knuckle, a telescopic arm, a pen clamping frame and the like. The whole machine design is ingenious, the structure is concise, the mounting and dismounting is convenient, the hardness and the stiffness are high, the maintenance is simple, and the reliability is high. Automatic, efficient and high-accuracy sectional line drawing can be performed on steel structures, and the drawing machine is an essential manufacture device in modern shipbuilding enterprises and has great significance for improvement of manufacturing technology levels, product quality and economic benefits of shipbuilding and oceanography engineering equipment.

Description

technical field [0001] The invention relates to a gantry-type hull segment marking machine, which can be used in shipbuilding, offshore drilling platforms, offshore steel structure module manufacturing and other projects, and belongs to the technical field of ships and ocean engineering. Background technique [0002] Shipbuilding and marine engineering equipment are manufactured in modular sections and welded together. The construction quality and cycle of the products depend on the closing accuracy and efficiency of the steel structure sections. In order to improve the technological level of loading and closing the hull sections, the joint surface between the sections and adjacent sections should be pre-treated to the closing tolerance in advance, which requires measuring, scribing and cutting the dimensions of each section. This scribing machine is to scribing after measuring the scale of the segment to prepare for the subsequent segment margin cutting. [0003] At pr...
