Problems solved by technology

High investment, long construction period, and underwater slides cannot be recycled
2) Airbag launch: use high-pressure inflated rubber airbags to bear the weight of the ship. The rolling deformation of the airbag and the weight of the ship combined with the slope of the land make the new ship launch smoothly. However, the airbag is prone to uneven internal pressure of the bag wall, and it is easy to cause delam

Abstract

The invention discloses a sliding track vehicle for dragging and launching a drilling ship. Roller wheels (4) are arranged at the bottom of a pulley (8), a hydraulic cylinder (5) is vertically arranged on the upper part of the pulley (8), and a piston (6) is arranged on the hydraulic cylinder (5). The sliding track vehicle, which is arranged on a track, shares the weight of the drilling ship, and the drilling ship is conveniently dragged and launched, so that the cost of a large ocean engineering drilling platform is reduced, a drilling platform ship is safely and steadily dragged and launched or semi-submerged, and the sliding track vehicle has the advantages of small construction amount, short construction time, low investment, high construction reliability and high generality; the cost of supporting facilities is reduced accordingly; the sliding track vehicle belongs to extremely-flexible carrying and launching technologies, has the remarkable advantages of labor conservation, time conservation, effortlessness, investment conservation, flexibility, safety, reliability, good comprehensive economic benefit and the like, and has a popularization value; the manufacturing cost of an ocean drilling platform is reduced.

Description

technical field [0001] The invention relates to equipment and devices for launching, pulling out or entering dry dock of ships in the field of marine engineering and ship product construction, especially a slide rail vehicle for dragging and launching a drilling ship. Background technique [0002] Ship launching is the process of moving the ship from the construction area to the water after the construction of the berth is basically completed. It is an important link in the ship building process, and it is also a relatively complicated process. There are many factors that affect the safety of launching a ship. It is necessary to set up a temporary prefabrication yard at the construction site, and use simple, convenient and cheap launching facilities as necessary assistance. [0003] Drilling ships are different from conventional cargo ships. They are engineering ships, and the average weight per unit volume is much larger than conventional ships. For example, its main dimen...
