Embodiment Construction

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Such as figure 1 As shown, the foldable guardrail according to the first embodiment of the present invention is used on the operating table 100 of the screw pump drainage wellhead of the offshore floating drilling platform. The foldable guardrail includes a guardrail unit 10 installed on the side of the console 100, and a base 20 fixedly mounted on the console 100 corresponding to the guardrail unit 10. The guardrail unit 10 is rotatably connected to the base 20, so that the guardrail unit 10 is relatively The console 100 can rotate back and forth between a first position and a second position. In the first position, the guardrail unit 10 stands vertically on the console 100, such as figure 1 As shown; in the s...

Abstract

The inventiondiscloses afoldable guardrail used in a screw rod pump liquid discharge well mouth operation platform. The foldable guardrail comprises a guardrail unit as well as a base, wherein the guardrail unit is mounted on a side of the operation platform; the base is mounted on the operation platform corresponding to the guardrail unit; the guardrail unit is rotationally connected with the base, so that the guardrail unit can rotate back and forth within a first position and a second position relative to the operation platform; atthe first position, the guardrail unit is vertically arranged on the operation platform; at the second position, the guardrail unit is horizontally placed on the operation platform. Due to rotational connection of the guardrail unit and the base, a guardrail can be arranged on the operation platform in a foldable manner without being hoisted or disassembled when the screw rod pump operation platform is mounted on a floating type drilling platform each time, so that the working efficiency is improved, the working time is shortened, and the working risk is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid drainage in offshore oil fields, in particular to a foldable guardrail used for a screw pump drainage wellhead operating platform. Background technique [0002] When the offshore floating drilling platform performs screw pump drainage, it is necessary to use the floating drilling platform screw pump drainage wellhead operation platform to realize the drainage. Since the wellhead operation platform is relatively high from the drilling floor, and with the ups and downs of the floating drilling platform, the distance between the drilling floor and the wellhead operation platform is constantly changing, in order to protect the safety of the staff standing on the wellhead operation platform , Guardrails are set outside the wellhead operation platform as one of the important safety measures for climbing operations to ensure the safety of relevant workers. [0003] The guardrail of the existing wellhead ...
