a boarding device

Abstract

The invention discloses embarking equipment. A lifting mechanism is arranged between a lifting platform and a motor vehicle chassis, and the height of the lifting mechanism can be adjusted. An intermediate ladder is arranged between the lifting platform and the chassis, and passengers get on and off a ship through an overturned ladder, the intermediate ladder, the lifting platform and an accommodation ladder. The lifting mechanism adopts a scissor-type lifting mechanism to drive the lifting platform to be adjusted vertically, the take-over height range is larger, and the demand for ro-ro passenger ship take-over in the larger range is met; and meanwhile, the gradient of the accommodation ladder is reduced, so that the ship is safer and more comfortable. Double pitch oil cylinders symmetrically arranged on the two sides are adopted, the pitch smoothness is improved, and safety of the passengers during embarking and disembarking is ensured.

Description

technical field [0001] The invention belongs to the technical field of design of auxiliary tools used by ships, and in particular relates to boarding equipment. Background technique [0002] The ro-ro passenger ship is also known as open up and down. It is a transport ship that uses a tractor to pull a semi-trailer or wheeled pallet loaded with boxes or other items of goods directly into and out of the cargo hold for loading and unloading. The cargo carried by the ro-ro passenger ship enters and exits the warehouse through its own power, and can carry passengers at the same time. It is mostly used for medium and short-distance sea transportation by inland river ferries. [0003] The ro-ro passenger ship rises and falls with the tide, and the heave, lateral movement, and longitudinal movement caused by the up and down operation of the ro-ro vehicle have a large distance. However, most of the existing boarding bridges are gantry track type, which are connected to the cruise s...

AI Technical Summary

Problems solved by technology

[0004] 1) The working platform of the existing boarding ladder and the chassis of the car body are relatively fixed, and cannot be lifted, so the height range of the boarding ladder is small

[0005] 2) The pushing mechanism of the sliding platform is driven by rack and pinion, which has a bloated structure and high cost

[0006] 3) The overall swing of the gangway track does not have an independent rotating platform, the swing angle is small, the rigidity of the working platform structure is high, and the swing energy consumption is high

[0007] 4) Use a single pitching cylinder to drive the gangway, the gangway shakes a lot, and the stability is poor, which is not conducive to the safety of passengers getting on and off the ship
