AI Technical Summary

Problems solved by technology

The disadvantage of this kind of trestle is that the erection and withdrawal speed is slow, the operation is cumbersome, and the labor intensity is high. Especially in case of emergency, it is difficult to quickly complete the withdrawal in a short time.

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] As shown in the drawings, the present invention is mainly composed of a base 2, a flat car 4, a running mechanism 14, a door-shaped support 5, a slewing mechanism 18, a winch 13, a bridge span 7, a hydraulic system, an electrical system, etc., wherein the hydraulic system , The electrical system constitutes the trestle control system. The connections and functions of each part of the entire trestle bridge are:

[0021] The base 2 is directly fixed on the deck of the offshore fixed platform 1 . A slideway 3 is provided on the base 2 , and a roller 17 is provided on the flat car 4 , which can move back and forth in a straight line in the slideway 3 through the driving of the traveling mechanism 14 arranged between the base 2 and the flat car 4 . During operation, the flat car 4 and the components on it can be moved to the required overlapping position accordin...

Abstract

The invention discloses a machinery-driven foldable trestle bridge, which mainly comprises a base, a platform wagon, a walking mechanism, a portal support, a rotating mechanism, a winch, a hydraulic system, an electrical system and the like, wherein the hydraulic system and the electrical system form a trestle bridge control system. The bridge span is foldable, and can consist of two, three or four segments; a hydraulic turnover mechanism is arranged among the bridge segments; and when the bridge is used, the hydraulic turnover mechanism unfolds or folds the bridge span. The foldable machinery-driven trestle bridge has the advantages of small occupied area, low labor intensity, convenient operation, quick bridging and folding, and the like.

Description

technical field [0001] The invention relates to a foldable trestle, in particular to a rapid erection and withdrawal of the trestle by mechanical means. Background technique [0002] During offshore oil drilling operations, it is often necessary to connect a service fixed platform to a fixed drilling platform to serve the drilling platform. When the service platform is connected to the drilling platform, trestle bridges need to be built on the two platforms for the passage of personnel and small equipment, and cables, fire pipelines and other facilities should be laid on the edge of the trestle bridge. Most of the existing trestles are integral truss type at present, usually transported to the lapping platform by a cargo ship during installation, and then the trestle is hoisted to the lapping point on the platform deck by a crane on the platform for erection. When the service platform is evacuated, the cargo ship is also required to make an intermediate transition to disman...
