The present invention provides a kind of outer defeated convenient, quick, safe multifunctional self-elevating supporting platform for ocean oil field hydraulic multifunctional delivery trestle for solving the technical problem that exists in the known technology.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of multifunctional self-elevating supporting platform for ocean oil field hydraulic multifunctional delivery trestle, comprise the base that is installed on the platform, be installed in the frame support on the base, be vertically mounted on the rotating spindle on the support, be installed in the cantilever pontic on the rotating spindle, be installed in all kinds of external transport pipeline and cables with rapid pipe joint on the pontic, and the drive unit of rotating spindle, be hinged between described cantilever pontic and the rotating spindle, cantilever pontic intermediate portion is equipped with hanger, the rotating spindle top is equipped with static pulley, the rotating spindle waist is equipped with winch and the support thereof that rotates with rotating spindle, and the traction steel-cable of winch connects hanger by static pulley.
The present invention can also adopt following technological scheme:
Described drive unit is in frame bottom and rotating spindle lower end gear housing to be installed, be vertically installed with oil hydraulic motor on the gear housing, output pinion is installed on the hydraulic motor output shaft, the rotating spindle lower end is equipped with the gearwheel with the output pinion engagement, and the support rear side is provided with the hydraulic power unit that power is provided to oil hydraulic motor.
The frame structure that described cantilever pontic is formed by steel-pipe welding, its cross section is L-shaped, and the outside of cantilever pontic and bottom are equipped with external transport pipeline side by side, and its installed inside has outer transmission cable, and People's Bank of China's guardrail also is installed on the cantilever pontic.
Described cantilever pontic front end is equipped with universal rolling wheel.
Advantage and good effect that the present invention has are:
Because the cantilever pontic horizontally rotates by driving device for hydraulic motor with hinged rotating spindle, the cantilever pontic can utilize winch to raise by the static pulley on the rotating spindle or reduce angle, can satisfy like this different azimuth overlap joint trestle and carry out outer transporting operation requirement; Be mounted with all kinds of external transport pipelines with rapid pipe joint and cable on the pontic, can realize the quick outer transporting operation service between offshore production facility, greatly improved working efficiency; Utilize the structured steel pipe of pontic own to make external transport pipeline, alleviated additional external transport pipeline weight; Maintenance channel is set on the pontic, makes things convenient for the installation and maintenance of pipeline and cable; Passage cover plate is set on the maintenance channel, under the passage cover plate external transport pipeline is installed, save the pipeline installing space; The present invention also has mechanization degree height, operator are few, labor intensity is low, safe and reliable advantage in addition.
