Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, structure of the present invention is, comprise body pillar 3, body pillar 3 upper surface center is provided with ear seat 16, ear seat 16 is upwards hinged with the otic placode D18 of rotating seat 10 lower floor's platform lower surface by bearing pin 17, rotating seat 10 upper strata platform is fixedly connected with pivoting support 9 bearing outer ring, pivoting support 9 bearing inner race is upwards fixedly connected with holder 7, holder 7 is provided with motor 6, the power transmission shaft termination of motor 6 is provided with pinion 4, pinion 4 outer face is provided with pressing plate 5, and pinion 4 engages with the external tooth of pivoting support 9 bearing outer ring;
Rotating seat 10 lower floor's platform side is installed with otic placode C11, otic placode C11 and hydraulic jack B13 one end hinged, the holder of the hydraulic jack B13 other end (piston rod end) and body pillar 3 upper surface is hinged;
A guide sleeve 15 is respectively installed with, along being provided with a suspension hook 14 under each guide sleeve 15 outer end at body pillar 3 both ends; Be installed with a hydraulic jack A2 respectively in guide sleeve 15 inboard, body pillar 3 two ends, the otic placode A1 that the piston rod of each hydraulic jack A2 passes outwardly on bearing pin 12 and guide sleeve 15 is hinged;
Body pillar 3 is provided with level sensor 19, for detecting the horizontal level of body pillar 3 in real time.
There is otic placode B8 at holder 7 upper weld, when the single operation of needs movement, the forearm head of folding arm grab pipe machine is fixedly connected with otic placode B8 by articulated manner, crawl movement operation can be carried out thereupon.
Motor 6 driven gear 4, gear 4 engages and drives pivoting support 9, realizes rotating seat 10, body pillar 3 relative to the rotation of holder 7.Body pillar 3 can be rotated around pin joint in the vertical direction and be ensured that single with marine riser 20 is axially parallel, is detected in real time, by the rotational angle of the flexible adjustment body pillar 3 of hydraulic jack B13 piston rod by level sensor 19.
The hydraulic jack A2 of body pillar 3 two ends installation, guide sleeve 15, suspension hook 14 are symmetrical structure, and two hydraulic jack A2 can synchronous operation.Suspension hook 14 can move horizontally along the guide sleeve 15 at body pillar 3 two ends; Spacing adjustment between two suspension hooks 14 realizes by the piston rod of respective hydraulic jack A2 is flexible.
Operating principle of the present invention is:
Before operation process, be connected with the forearm head of folding arm grab pipe machine by articulated manner, grab pipe machine by overall revolution and hoisting arm expansion by handling of the present invention to by single for marine riser to be captured top.
When crawl marine riser is single, the hydraulic jack A2 piston rod that body pillar 3 is installed is released, suspension hook 14 is placed in marine riser two ends, after grab pipe machine arm transfers to the correct position above marine riser single 20, the piston rod of hydraulic jack A2 shrinks, by the two ends pulling suspension hook 14 to be inserted into marine riser single 20, then clamp, then carry out the subsequent jobs such as lifting movement.
In movement process, need motor 6 that pivoting support 9 can be driven to rotate according to operation, make body pillar 3 drive marine riser single 20 to rotate in the horizontal direction; Make body pillar 3 and marine riser single 20 parallel in the vertical direction according to instruction hydraulic jack B13, its angle can detect feedback by level sensor 19 simultaneously.Marine riser single 20 loop wheel machine entirety drive put in place after, hydraulic jack A2 piston rod release, can depart from conveying put in place single, repeat said process, the movement that whole marine riser is single can be realized.
Meanwhile, when marine riser single 20 is recovered to storage area, then oppositely perform said process.
