Special gang plank mechanism for vehicle-passenger ferry on Yangtze River

Abstract

The invention provides a special gang plank mechanism for a vehicle-passenger ferry on Yangtze River. The special gang plank mechanism comprises hanging brackets, a deck, fixed pulley brackets, fixedpulleys, motor shells, winding motors, steering wheel brackets, steering wheels, hinge supports, gang planks, connecting rings, steel wire ropes, inclined pull rods, locking blocks and locking cylinders; the hanging brackets are arranged on the two sides of the deck; the fixed pulleys are rotationally connected with the fixed pulley brackets; the winding motors are arranged in the motor shells; the steering wheels realize rotation with the top ends of the steering wheel brackets; the hinge supports are rotationally connected with the gang planks through shafts; one ends of the steel wire ropesare bound with the connecting rings, and the steel wire ropes slide through the fixed pulleys and the steering wheels, and realize winding fixation with the winding motors; the inclined pull rods arearranged on one sides of the hanging brackets, the bottom ends of the inclined pull rods are rotationally connected with the locking blocks; and the locking cylinders are arranged on one sides of thetop surfaces of the locking blocks. According to the special gang plank mechanism for the vehicle-passenger ferry on the Yangtze River, auxiliary rigid connection is carried out between the gang planks and the hanging brackets through the inclined pull rods, so that the connection strength of the gang planks is improved, the gang planks are prevented from the bounce phenomenon caused by externalforce, and the service life is long.

Description

technical field [0001] The invention relates to the field of ships, in particular to a special springboard mechanism for a car-passenger ferry on the Yangtze River. Background technique [0002] Ferries, also known as ferries, are transport ships that sail between rivers, lakes, straits and islands. They are mainly used to carry passengers, goods, vehicles and trains across rivers, lakes and straits. There are many types of ferries, including passenger ferries, car ferries, train ferries and new railway liaison ships. Generally, the hull structure of the ferry is simple, and the equipment on board is simple, especially the ferry used for the transition in the river. Generally, there are two sets of power devices, which are propelled by double propellers, and have good maneuverability. They can easily dock at the dock, get on and off passengers, and load and unload goods; they have good stability. [0003] The ferry is convenient for cars and passengers to get on and off th...

AI Technical Summary

Problems solved by technology

There are various forms of springboards in various forms of ferries. The existing springboards are usually placed on the shore during the erection process. During the process of boarding and disembarking passengers, the springboards will bounce due to external force and gravity, and the stability of the springboards is relatively high. Poor, pedestrians are prone to fall, and the safety performance is low; when the ferry is running, the springboard is in a retracted state, and the springboard is pulled up and folded by ropes. When encountering strong wind or other external forces during driving, the folded springboard still exists The bouncing phenomenon can easily lead to damage to the springboard structure or even cause the springboard to fall
