Embodiment Construction

[0021] Such as Figure 1-5 Shown, trestle 2 of the present invention adopts I shape, is provided with hydraulic expansion mechanism 4, flange 5, pedestrian deck 6, trestle guardrail 7. The hydraulic telescopic mechanism 4 is welded on the movable platform deck 8, and the hydraulic telescopic mechanism 4 is made up of a hydraulic cylinder 14, a piston 11, a spring 17, a tongue post 15, a tongue post sheath 13, and a telescopic conversion handle 16. The flange 5 is provided with pre-opening holes 12, and the flange 5 is symmetrically welded below the two ends of the pedestrian deck 6; the trestle guardrail 7 is located at both ends of the pedestrian deck 6, and is connected to the side ends of the pedestrian deck 6 and the top of the flange 5 by welding. . The tongue column 15 of the hydraulic telescopic mechanism 4 snaps into the pre-opening hole 12, and the shape of the tongue post 15 snapping into the pre-opening hole 12 is an inclined plane. Since one side of the tongue pos...

Abstract

An auto-telescoping trestle bridge applicable to movable platforms comprises hydraulic telescoping mechanisms, flanges, a pedestrian deck, and trestle guardrails. The hydraulic telescoping mechanisms are welded on a deck of a movable platform. Each hydraulic telescoping mechanism comprises a hydraulic cylinder, a piston, a spring, a tongue pillar, a tongue pillar sheath, and a telescoping switch handle. Each flange is provided with premade holes. The flanges are symmetrically welded below two ends of the pedestrian deck. The trestle guardrails are arranged at two ends of the pedestrian deck and connected to the ends of the pedestrian deck and the tops of the flanges respectively by welding. The auto-telescoping trestle bridge has the advantages that safety risks of the movable platform trestle bridges are effectively decreased, the bridge is applicable to severe sea conditions, and platform desk area is greatly saved.

Description

technical field [0001] The invention relates to a trestle, in particular to an automatic telescopic trestle used for a movable platform in a marginal oil field. It belongs to the field of offshore oil engineering. Background technique [0002] In offshore engineering, trestle bridges are widely used as pedestrian passages and umbilical supports to connect unattended wellhead platforms, mooring cable platforms and simple wellhead platforms in marginal oil fields. [0003] Unattended wellhead platforms, tethered platforms, and simple wellhead platforms in marginal oil fields all rely on oil and gas processing platforms or movable jack-up platforms to complete the production and processing of crude oil, but the above platforms require periodic facility maintenance, so trestles need to be built , in the current trestle installation process, one is to use the crane-assisted method to complete the erection of the trestle. Due to the limitation of the deck area on some oil and gas...
