A retractable boarding trestle with position compensation

Abstract

The invention discloses a position compensation retractable boarding trestle. The position compensation retractable boarding trestle comprises a base, a rotary platform, a retractable trestle, a landing device, a rotary hydraulic motor and a variable amplitude cylinder; The retractable trestle comprises a main arm and a retractable arm; a steel guide rail is arranged on the main arm through an insulation fixing device, and the retractable arm is slidingly arranged on the main arm; the position compensation retractable boarding trestle also includes a position compensation control system and aposition compensation hydraulic system; the position compensation hydraulic system includes a power system, a rotary hydraulic system, a telescopic hydraulic system, and a variable amplitude hydraulicsystem. By using the structure of the invention, the lap joint of the retractable trestle is reliable, safe and efficient; the follow-up of the retractable trestle can be realized after the lap jointis completed, people can pass through the trestle smoothly and stably, and materials can be smoothly and stably conveyed through the trestle; and the load on the lap joint point can be reduced.

Description

Technical field [0001] The invention relates to a telescopic boarding trestle with position compensation. Background technique [0002] The bridge or trestle bridge is mainly used to transport people or goods. On land, the construction of the bridge is relatively simple, but the bridge used to transport people and materials between two ships at sea is relatively difficult to construct. Because the ship moves with each other, the bridge is generally built on a ship. If needed, a bridge is set between the two ships by overlapping. In the lap process, in order to achieve better overlap, the relative position between the bridge and another ship needs to be considered, otherwise the bridge and the ship will collide due to the floating of the ship; after the overlap is completed, It is also necessary to consider the relative position between the two ships. According to the relative position of the two ships, let the bridge be in a passive compensation state, so that normal use can be ...

AI Technical Summary

Problems solved by technology

The structure adjusts the position of the platform through active wave compensation, and then realizes the lap joint. However, since the ship is shaking, it is difficult to ensure the position between the gangway and the ship during the lap joint process. The lap joint is very difficult. After the lap joint, if If the gangway cannot be followed, it is easy to damage the structure, and it is impossible to pass people and transport materials smoothly
