Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of offshore platforms, in particular to a telescopic railing for an offshore oil platform. BACKGROUND

[0002] An offshore platform is a structure that houses the facilities needed to support the activities associated with the production and living of people at sea.

[0003] According to their structural characteristics and working conditions, offshore platforms can be classified into three categories: fixed, mobile and semi-fixed. Fixed platforms are directly supported by piles, enlarged footings or other structures and are fixed to the seabed. They can be classified into two types: pile-supported and gravity-based. Mobile platforms float on water or are supported on the seabed and can be moved from one well to another. They can be classified into two types: bottom-anchored and floating. In recent years, a new type of semi-fixed offshore platform has been developed. It can be fixed in deep water and is mobile. The tension leg platform belongs to this category.

[0004] Railing is installed around the offshore platform and in each functional area to provide protection for people and is an essential part of an offshore platform.

[0005] The existing railing of offshore platforms has the following problems:

[0006] The large number of railings requires a large number of packaging units, resulting in high transportation costs.

[0007] The railings come in different forms and there are a large number of them, which makes the on-site positioning and installation work very labor-intensive.

[0008] The original structure type has poor wind resistance and is prone to vibration and damage due to strong winds on the sea. SUMMARY

[0009] The present application aims to solve the problems in the prior art and provides a telescopic railing for an offshore oil platform.

[0010] The technical solution is as follows:

[0011] A telescopic railing for an offshore oil platform is provided. The railing is composed of a vertical rod, a handrail and a horizontal rod. The vertical rod is fixed below the handrail. The horizontal rod is provided with a middle fixed tube. The platform edge is provided with a lower fixed tube. The vertical rod, the middle fixed tube and the lower fixed tube are slidingly connected. The middle fixed tube, the lower fixed tube and the vertical rod are provided with corresponding pin holes. The middle fixed tube, the lower fixed tube and the vertical rod are connected by pins.

[0012] Further, the lower end of the vertical rod is provided with a limiting step. The limiting step and the lower end of the lower fixed tube are in limiting cooperation.

[0013] Further, the application also includes the following scheme:
