Automatic hydraulic side rolling-type oversize hatch cover

Abstract

The invention discloses an automatic hydraulic side rolling-type oversize hatch cover, which comprises a hatch cover, namely a thick steel plate. Four fixed pulleys are arranged around four corners of the hatch cover; a hydraulic motor is arranged between two upper fixed pulleys; at least one roller is arranged on the left side and the right side between an upper fixed pulley and a lower fixed pulley respectively; the roller, each fixed pulley and the hydraulic motor are connected by conveying ropes; a plurality of hatch cover compactors are uniformly distributed on four sides of the hatch cover and are used for compacting the hatch cover to ensure higher airtightness of the whole hatch cover; a support block is arranged between every two hatch cover compactors and is mainly used for supporting; and a limiter is arranged above the rollers on the left and right sides respectively and is used for limiting to ensure that the hatch cover is steadier during operation. The automatic hydraulic side rolling-type oversize hatch cover has the advantages of simple and practical structure, high work efficiency and the like.

Description

Technical field: [0001] The invention relates to an automatic side-rolling extra-large hatch cover, which is mainly suitable for some large ships. Background technique: [0002] At present, the working efficiency of some existing ship covers is not high, and some of them are opened manually, which is time-consuming and labor-intensive. It takes a long time to complete the whole process by machinery, and the opening area is relatively small. It is also facing one direction, the opening position and height are not enough, and the safety performance is not high. The hydraulic motor used is generally a piston. When the piston is damaged, it will not work normally. The pressure and temperature of the hydraulic system are relatively limited during work. If the temperature is too high or too low, it will not work normally. Generally, gears are used instead of rollers. The gear transmission is complicated, easy to wear, and the cost is high, which is not conducive to market promotio...
