Automatic hydraulic side rolling type super-large hatch cover

Abstract

The invention discloses an automatic hydraulic side rolling type super-large hatch cover, which comprises a hatch cover. A fixed pulley is arranged around four corners of the hatch cover respectively, a hydraulic motor is arranged between the transverse upper two fixed pulleys, and at least one roller is arranged between the vertical two fixed pulleys; the roller, each fixed pulley and the hydraulic motor are connected through drawing steel wire ropes; a plurality of hatch cover compactors are uniformly distributed on four edges of the hatch cover, and a supporting cushion block is arranged between every adjacent two hatch cover compactors; a plurality of limiters are also uniformly arranged on the four edges of the hatch cover; the limiters and the hatch cover compactors are distributed at intervals; and the bottom of the supporting cushion block is connected with a supporting rubber, the bottom of the supporting rubber is connected with an onboard cushion block, the onboard cushion block is positioned on a hull, and the joint of the hatch cover and the hull is provided with at least one sealing rubber. The super-large hatch cover has the advantages of simple structure, high practicability 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 hatch covers of most ships are not well sealed. The super-long steel plates that make up the hatch covers are difficult to tailor and weld. They are prone to water leakage when it rains, and the dry environment of the cargo cannot be well guaranteed. Locking, safety and operability are not very good, and it cannot well reflect the ergonomics of man-machine integration. The limiter generally adopts a one-way limit structure, the limit effect is not very good, and it cannot guarantee the cabin well. The operation of the cover is completed under stable conditions. The large structure makes it very difficult to control the size and deformation. The later painting stage of the hatch cover also requires a lot of man-hours, so the whole process cannot be completed efficiently. Invention co...

[0002] At present, the hatch covers of most ships are not well sealed. The super-long steel plates that make up the hatch covers are difficult to tailor and weld. They are prone to water leakage when it rains, and the dry environment of the cargo cannot be well guaranteed. Locking, safety and operability are not very good, and it cannot well reflect the ergonomics of man-machine integration. The limiter generally adopts a one-way limit structure, the limit effect is not very good, and it cannot guarantee the cabin well. The operation of the cover is completed under stable conditions, the size and deformation of the large structure are very difficult to control, and the man-hours in the later painting stage of the hatch cover are also relatively large, so the whole process cannot be completed efficiently
