Marine oil field multifunctional self-elevating supporting platform pedestrian hydraulic telescopic trestle

Abstract

The invention relates to a marine oil field multifunctional self-elevating supporting platform pedestrian hydraulic telescopic trestle which is characterized in that a rotatable support with an inner gear ring is installed on a pedestal, a door frame is installed on the rotatable support, a guide wheel group is installed at the upper end of the door frame, a fixed bridge section is articulated on the rotatable support, guide wheel groups are installed at both ends of the bottom of the fixed bridge section, drag wire ropes are installed on the guide wheel group of the door frame and the guide wheel groups of the fixed bridge section, a winding machine for receiving and releasing the wire ropes is installed on the door frame, an extensile telescopic bridge section is movably installed in the fixed bridge section, four parallel guide rails are installed in the fixed bridge section, a roller rolling along the guide rail is correspondingly installed on the telescopic bridge section, a rack is installed at the bottom of the telescopic bridge section, and a gear engaged with the rack and a hydraulic motor are installed at the bottom of the front end of the fixed bridge section. Thus, the trestle has the functions of turning positions, elevating angles and stretching, and the rapid connection among marine production facilities can be realized, thereby greatly improving the work efficiency; and in addition, the invention also has the advantages of light weight, high mechanization degree, fewer operating staff, low labor intensity, safety and reliability.

Description

technical field [0001] The invention relates to a pedestrian trestle bridge used between offshore platforms, in particular to a pedestrian hydraulic telescopic trestle bridge for marine oilfield multifunctional self-elevating support platforms. Background technique [0002] Petroleum, as the main source of world energy supply, has become an important strategic resource to promote national economic development. In recent years, the growth of offshore oil and gas production has become the main source of my country's self-produced oil and gas increment. There are a large number of jack-up drilling platforms in China, and with the construction of offshore fixed platforms, there is a serious shortage of supporting multi-functional platforms. Moreover, the existing multifunctional platforms have single functions and limited service capabilities. For example, the current connection of offshore production facilities, including the connection between fixed platforms and between fix...

Problems solved by technology

The integral steel frame trestle needs to be hoisted into place by means of a crane during operation and service; the lap length of the foldable steel frame trestle is fixed and cannot be adjusted arbitrarily, so the service capacity is limited to a certain extent
