Bridge device

Abstract

The invention discloses a bridge device. The bridge device comprises a base and a truss, wherein the base is provided with a rotary platform; the rotary platform is provided with a room body; the side wall of the room body is provided with a door and windows; a driving seat is arranged in the room body; the truss comprises a fixed truss and a movable truss which are telescopically matched by means of a rolling mechanism; the end, which is not connected with the movable truss, of the fixed truss is fixedly arranged on the rotary platform. The bridge device is characterized in that the door is positioned on a rear side wall of the room body, wherein the windows comprise a front window and side windows; the room body is provided with an outer layer, a thermal insulation layer and an interior layer from inside to outside in sequence. The interior layer is a fire-proof plate. An electric control part and a hydraulic control part are arranged in the room body, and the two parts are connected with a corresponding executing mechanism by means of a circuit and a pipeline respectively. A driving cab can guarantee normal work of an operator; the truss is low in production cost, has a simple structure and can also avoid discomfort brought to a truss riding person. The bridge device can be used for people and material migration between a living platform and a sea depot ship.

Description

technical field [0001] The invention relates to a bridge crossing device. Specifically, it is a bridge crossing device used to control the passage or migration of personnel and limited-weight materials between the marine living platform and the offshore supply ship or offshore drilling platform. Background technique [0002] With the massive development of terrestrial resources, terrestrial resources are becoming less and less. Therefore, in recent years, countries have gradually attached importance to the development of marine resources. To realize the development of marine resources, it is inseparable from the marine living platform. On the marine living platform, it is often necessary to replenish, transfer materials or transfer personnel through offshore supply ships. The offshore drilling platform or the offshore supply ship needs to be connected with the marine living platform by means of a bridge device, so as to carry out the transportation of personnel or materia...

AI Technical Summary

Problems solved by technology

If there are too many reinforcing rods, not only more materials, more welding spots, complicated welding process, high production cost, but also increase the weight of the truss

And because the driving mechanism is a hydraulic pump, it needs to be equipped with a hydraulic workstation and a lot of hydraulic pipelines, which not only complicates the truss structure, but also increases the volume of the truss

In addition, since the buffer mechanism is a metal spring, it will vibrate when it collides with the limit mechanism, which will bring discomfort to the occupants of the truss
