Slewing gangplank

Abstract

The invention relates to a slewing gangplank. The slewing gangplank is characterized by comprising a base (1), the base (1) is arranged on a deck and provided with a slewing bearing (2), an upper bearing platform (3) is arranged on the slewing bearing (2), a slewing oil cylinder (4) is connected between the slewing bearing (2) and the upper bearing platform (3), a gangplank frame (5) is hinged to one end of the upper bearing platform (3), and a derricking oil cylinder (6) is fixedly arranged between the upper bearing platform (3) and the gangplank frame (5); a hydraulic power pack (12) and a control cabinet (13) are arranged in the slewing gangplank, the control cabinet (13) is connected to the hydraulic power pack (12) and used for controlling an oil way, the hydraulic power pack (12) is connected with the slewing oil cylinder (4) and the derricking oil cylinder (6), and a manual pump is arranged in the hydraulic power pack (12). An oil pump is driven by an engine to work so as to convert electric energy into high-pressure hydraulic energy, a worker operates a control system so that high-pressure hydraulic oil can push a piston rod of the corresponding oil cylinder, the corresponding oil cylinder stretches or retracts, derricking and slewing of the gangplank can be controlled conveniently, it is unnecessary to move the gangplank with manpower or a crane, the gangplank saves time and labor, is convenient to operate and can be folded and unfolded stably, and a storage frame on the deck can prevent the gangplank from swinging during navigation of a ship.

Description

technical field [0001] The invention relates to a rotary wharf ladder, which is installed on the decks of various ships. The rotary wharf ladder device converts electric energy into high-pressure hydraulic energy through an electric motor to drive an oil pump. The personnel operation control system makes the high-pressure hydraulic oil push the cylinder piston rod, Make the oil cylinder extend or contract, and then drive the wharf ladder to change amplitude or turn. Background technique [0002] Dock ladders (ie springboards) are placed on the decks of various ships to connect the ship and the dock so that the crew can walk to the dock. The usual wharf ladder is placed on the deck. When it needs to be used, it must be manually lifted to the wharf. If the wharf ladder is long, it needs to be put in place with a crane, but the operation efficiency of manual or crane operation is very low. , and inconvenient; at the same time, when the dock ladder is placed on the deck, it is ...

Problems solved by technology

The usual wharf ladder is placed on the deck. When it needs to be used, it must be manually lifted to the wharf. If the wharf ladder is long, it needs to be put in place with a crane, but the operation efficiency of manual or crane operation is very low. , and inconvenient; at the same time, when the dock ladder is placed on the deck, it is easy to shake with the ship, which is very unsafe
