Second-deck positioning guide rail mechanism

Abstract

The invention discloses a second-deck positioning guide rail mechanism which is arranged on the cabin wall of a multipurpose ship. The second-deck positioning guide rail mechanism comprises four elongated guide rail supports, and a bracket support is arranged on each guide rail support at the same height. Each bracket support comprises a pivot shaft parallel to the guide rail supports and a support body arranged on one side of the pivot shaft, upper pivot seats and lower pivot seats in connection with the pivot shafts are connected with the guide rail supports, lower oil cylinders with the axes parallel to the guide rail supports are arranged in the support bodies, and the upper ends of pistons of the lower oil cylinders are connected with support blocks. Upper oil cylinders with the axes perpendicular to the cabin wall surface are arranged above the bracket supports, pistons are arranged at two ends of the upper oil cylinders, the outer ends of the pistons are respectively connected with front ejector blocks and rear ejector blocks, tension springs are arranged between the front ejector blocks and the rear ejector blocks, and the bottoms of the lower oil cylinders are communicated with the upper oil cylinders through hydraulic pipelines. The second-deck positioning guide rail mechanism effectively solves the problem that a second deck is easy to displace to affect positioning effect of the second deck or damage rails of the cabin wall in the prior art and has high practical value.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a second-deck positioning guide rail mechanism. Background technique [0002] The bulkhead track on a multi-purpose ship can be used to fix the second deck, and the four corners of the second deck are limited by the track composed of four angle steels to prevent the second deck from moving in the cabin; when the multi-purpose ship needs to transport denser cargo such as When goods such as steel products, steel plates, and steel coils are used, these bulky goods can only be placed at the bottom of the hold. After the cargo at the bottom of the cabin is placed, the second deck is placed on the bulkhead track of the multi-purpose ship in an elevated manner using four corbels of equal height set on the four bulkhead tracks. At this time, the bottom surface of the second deck and the bottom of the cabin The space between them is used to load steel, steel plates, steel coils ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem in the prior art that the second deck is easy to shift, which affects the positioning effect of the second deck or causes damage to the bulkhead track, and provides a second deck positioning guide rail mechanism that can conveniently fix the second deck

[0004] Another object of the present invention is to solve the problem that the corbel support position of the bulkhead track in the prior art is fixed, which easily leads to the waste of cabin space, and to provide a second-deck positioning guide rail mechanism with adjustable corbel support height and high cabin space utilization
