Movable trestle

Abstract

The invention discloses a movable trestle which comprises a trestle body, steel cables, an eye plate, a hanging bracket, a lifting winch, a guide rail and a displacement winch. The trestle body is hinged to the hanging bracket through the eye plate. The rail and the displacement winch are fixedly installed on a deck perpendicular to a ship board and are connected through the steel cables. The lifting winch is installed on a bottom frame of the hanging bracket, the steel cables wound around the lifting winch are directly connected with pulleys on the two sides of the middle of the trestle body through a pulley system installed on the hanging bracket, and therefore a vertical swing structure of the trestle body with the eye plate as a hinging point is formed. The hanging bracket is dragged by the displacement winch through the wound steel cables to reciprocate along the rail. The trestle body is in a flatly-placed state, can be moved to the inner side of the ship board along with the hanging bracket so as to be in a hidden state and can be in an erected state when moved reversely. The movable trestle is prepared for a ship and can be autonomously erected when the ship is moored at a wharf.

Description

technical field [0001] The present invention relates to a kind of marine equipment, in particular, the present invention relates to a kind of trestle for staff to board and disembark, especially a kind of trestle which can be moved and stored. Background technique [0002] The trestle is a strip-shaped plate component. It is a pedestrian passage erected between the ship and the dock when the ship is berthed at the dock, and it can also be used as a convenient passage between ships at adjacent berths. Under normal conditions, the trestle is equipped by the terminal and is responsible for the specific erection work. Because the trestle bridge is more than 10 meters long and weighs several hundred kilograms, it is difficult to erect it manually, and it requires a lot of labor and takes a long time. At present, most berths generally use cranes to hoist trestles efficiently. Although the trestle bridge in the prior art has simple structure and low manufacturing cost, it can ful...

Problems solved by technology

However, every time the ship arrives at the port, it has to rely on the cooperation of the wharf to realize the erection of the trestle. Practice has proved that the erection of trestles with this structure is greatly affected by human factors, and the timeliness is poor. It is difficult for the ship to be erected effectively in the first time.
