Device and method for machining waterstop structure of arc-shaped door of ship lift and waterstop structure

Abstract

The invention discloses a waterstop structure machining device, a method and waterstop structures of an arc-shaped door of a ship lift, and relates to the technical field of mechanical machining devices. The machining device comprises a main shaft which is horizontally erected, and expansion hubs and side machining components are sequentially arranged at the two ends of the main shaft from outside to inside; and a bottom waterstop machining component is arranged at the position, between the two side machining components, of the main shaft. According to the device, the machining period is shortened, the requirement for the coaxiality between two arc-shaped waterstop plates and between two arc-shaped rails is ensured, and the requirement for the radian of a bottom waterstop plate is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a water-stop structure processing device and method for an arc door in a ship lift, and a water-stop structure. Background technique [0002] In the ship lift, the water-stop structure of the arc door is set at both ends of the ship-bearing compartment. see figure 1 As shown, each water-stop structure is a semi-enclosed frame structure composed of a bottom wall and two side walls, with its opening facing upwards, the width of the bottom wall can reach 10 to 20 meters, and the height of the side walls is 5 meters to 10 meters . The upper surface of the bottom wall is provided with a bottom wall boss 150, and the cross section of the bottom wall boss 150 is a right-angled trapezoid, and the edge at the right angle at the bottom of the bottom wall boss is the rear edge of the bottom wall, and the bottom wall boss 150 At the edge of the top of the inclined ...

Problems solved by technology

[0003] At present, the water-stop structures of the above-mentioned arc-shaped doors that have been built or are under construction at home and abroad all need to be processed again. The processing adopts a step-by-step and block-by-block processing method. The arc-shaped track 120 is processed separately. These processing methods require multiple repeated positioning of the tooling, resulting in a long processing cycle, and cannot ensure the coaxiality requirements between the two arc-shaped water stop plates and between the two arc-shaped tracks.

[0004] In addition, when the arc door opens and closes, the water stop rubber on the arc door structure will rub against the bottom water stop plate 100. The water stop rubber belt has a certain arc, and the current bottom water stop plate 100 is mostly made by plane milling. processing, so it is a plane structure, and there is a line contact between the water-stop rubber and the bottom water-stop plate 100, which accelerates the wear of the water-stop rubber during use

When the arc door is closed, the water-stop rubber installed on the arc-shaped door structure will be pressed against the bottom water-stop plate 100, the former has a radian, and the outer surface of the latter is flat, which will also affect the realization of the water sealing effect
