Description
Technical field
The invention belongs to offshore oil drilling oil production equipment field, relate to a kind of Offshore Drilling Riser or the production riser Platform Deck equipment that support, grip tube string and lift heavy thing are used in installation, unloading process.
Background technology
Chuck is as one of sea oil drilling and production key equipment, and clamping when its function is mainly used in single connection of marine riser or dismounting, support and suspention marine riser string and equipment such as BOP under water are convenient to connect fast and dismounting marine riser jointing; In addition, with the supporting use of universal joint, the installation site is directly over the drilling well rotating disk usually for chuck.
At present, more common chuck form mainly contains gate-type and hydraulic pressure turns over several structures such as pawl formula.The gate-type chuck is more traditional a kind of form, and this structure is by the opening and closing movement of sliding jaw, realizes operations such as riser system is transferred, supported, installation, outstanding advantage is simple in structure, subject matter is that volume, weight are bigger, and the production and processing difficult point is many, and cost is higher.Hydraulic pressure turns over claw chuck when work claw and digs upwards that can to remove marine riser smoothly single, claw is in level and guarantees to support, install marine riser, advantage is that volume is little, in light weight, shortcoming is the control system more complicated, the relative loaded area of claw is less than normal, and the material property and the heat treatment performance of claw are had relatively high expectations.
The invention discloses a kind of hydraulic telescopic arm two halves dock chuck, during this device busy, realize switch motion by the Driven by Hydraulic Cylinder support arm.Whole double formula structure, the profit of adopting
In processing, transportation and installation; Adopt the parallel hydraulic control loop, be beneficial to being synchronized with the movement of telescopic arm; And be provided with travel control switch, and can realize the accurately spacing of telescopic arm, have good weight-bearing function.
Summary of the invention
It is flexible to the objective of the invention is to design a kind of driving, and processing, easy for installation has the Offshore Drilling Riser chuck assembly of support effect greatly.
Specifically, a kind of hydraulic telescopic arm two halves dock riser spider, it is made up of upper right supporting plate, connecting pin, upper left supporting plate, telescopic arm, bracing frame, hydraulic cylinder, hydraulic control system, snap joint, lower-left supporting plate, bottom right supporting plate, rotation suspension ring, supporting vertical plate and safety pin; Upper right supporting plate and bottom right supporting plate link together by supporting vertical plate and constitute right semi-frame body; Upper left supporting plate and lower-left supporting plate link together by supporting vertical plate and constitute left semi-frame body; Right semi-frame body and left semi-frame body link together by connecting pin; Telescopic arm is installed and to be connected in the bracing frame under the push-and-pull of hydraulic cylinder relatively that the chuck hub through hole radially moves; Hydraulic control system is connected with hydraulic power supply with hydraulic cylinder respectively with snap joint; Safety pin is installed between telescopic arm and the mounting plate when telescopic arm arrives the chucking position.
Advantage of the present invention: simple in structure, drive flexibly, connect reliably, manufacture advantages such as simple and easy, easy for installation.Can be applied to the drillng operation under various marine sites, the sea conditions well, have macroeconomic performance and good Practical Performance preferably.
Description of drawings
Fig. 1 is a hydraulic telescopic arm two halves dock riser spider structural representation of the present invention.
Among Fig. 1, the upper right supporting plate of 1-, 2-connecting pin, the upper left supporting plate of 3-, 4-telescopic arm, 5-bracing frame, 6-hydraulic cylinder, 7-hydraulic control system, 8-snap joint, 9-lower-left supporting plate, 10-bottom right supporting plate, 11-rotation suspension ring, 12-supporting vertical plate, 13-safety pin.
The specific embodiment
Provided the hydraulic telescopic arm two halves dock riser spider structure of four jiaos of symmetrical structures with four telescopic arms and bracing frame as Fig. 1.Upper right supporting plate 1 and bottom right supporting plate 10 link together by supporting vertical plate 12 and constitute right semi-frame body, and upper left supporting plate 3 and lower-left supporting plate 9 link together by supporting vertical plate 12 and constitute left semi-frame body, and right semi-frame body and left semi-frame body link together by connecting pin 2; Telescopic arm 4 is connected with bracing frame 5, and under the push-and-pull of hydraulic cylinder 6, bracing frame 5 drives telescopic arm 4 relative chuck hub through holes and radially moves; Hydraulic control system 7 is connected with hydraulic power supply with hydraulic cylinder 6 respectively with snap joint 8; Safety pin 13 is installed between telescopic arm 4 and the mounting plate when telescopic arm 4 arrives the chucking position, plays the effect of location.By controlled hydraulic system, under the promotion of hydraulic cylinder, telescopic arm stretches out or withdraws along guide rail, realizes functions such as the riser system chucking by the chuck hub through hole, support, suspensions.
The quantity that is subjected to the telescopic arm 4 of hydraulic control system 7 and hydraulic cylinder 6 push-and-pulls among the present invention can be 2,3 or 4, and relative chuck hub through hole symmetrical distribution while stretching motion.Concrete quantity is according to the decision of chuck size, and the telescopic arm symmetric arrangement gets final product.
Drive each telescopic arm 4 flexible hydraulic cylinder 6 and hydraulic control system 7 and adopt 1 group or the many groups of employing.Use travel control switch or displacement transducer to limit the position of telescopic arm 4.Supporting frame is the two halves split-type structural or adopts monolithic construction.Power source is for surging or pneumatic.
Operating principle of the present invention is: snap joint 8 is connected with hydraulic power supply, and by hydraulic control system 7 push-and-pull hydraulic cylinders 6, drive bracing frame 5 and telescopic arm 4 radially stretch out with respect to the chuck hub through hole or withdraw; Guarantee the travel position of telescopic arm 4 by travel control switch; Telescopic arm 4 arrives when stretching out the status pole extreme position, locks with safety pin 13, prevents that accident takes place in the installation process; Telescopic arm 4 stretches out, when promptly being positioned at extreme position I, and chucking or support riser member when being used to marine riser is installed, and when non-drilling condition riser system is separated, be used to hang marine riser; Telescopic arm 4 withdrawal, when promptly being positioned at extreme position II, the single and buoyancy tank of marine riser all can pass through smoothly, realizes transferring the marine riser action; Left and right sides supporting plate adopts the design of two halves symmetrical expression, convenient processing, and have good replaceability; The rotation suspension ring make things convenient for the lifting and the assembling of hydraulic telescopic type chuck.
