Abstract
The utility model relates to integral moving equipment of an offshore drilling platform base and an offshore drilling platform derrick. The utility model is characterized in that a rear ear seat of an oil cylinder of the utility model is connected with an ear seat of the derrick, a front ear seat of the oil cylinder is connected with an ear seat of a prying seat, stepping blocks are connected with the prying seat in an assembly mode, stepping holes which are corresponding to holes on a slide rail and are matched with the stepping blocks in an adoption mode are arranged on a bottom plate of the prying seat, each corner position of the prying seat is provided with a guide block, and both sides of the derrick (or the base) are respectively provided with a set of moving equipment. The oil cylinder pushes the prying seat to be inserted into the stepping holes of the bottom plate of the prying seat and the stepping holes of the slide rail by the stepping blocks to complete one step movement, and then a piston of the oil cylinder is retracted, the stepping blocks are turned over, the prying seat is inserted into the other hole, and a piston rod of the oil cylinder is pushed to complete next one step movement, so the integral step movement of the derrick (or the base) is realized by such circulation. The moving equipment aims at the movement of an offshore drilling platform in a limited area to complete the drilling operation of a plurality of wells. The utility model has the advantage of high automatization degree. The utility model enhances work efficiency, improves a labour condition and provides equipment guarantee for safe production.
Description
Technical field the utility model belongs to the marine rig MOVING STRUCTURE, specifically a kind of marine rig platform base, the whole mobile device of derrick.
The former Soviet Union's 931 marine rig platforms (a complete set of second-hand equipment) were once buied by background technology CNOOC, CNOOC in 2004 entrust the applicant with the original platform derrick hoist, base parallel motion, system maintenance recover, to satisfy operating needs and, to satisfy working condition requirement fully with the hydraulic efficiency pressure system transformation of domesticizing.The matching used mobile device of 931 marine rig platforms institute of the former Soviet Union is inserted the stepping piece for manually changing, promptly,, prize the stepping piece and insert in the adjacent hole, slideway the place ahead by manually extracting set pin along with the moving of drilling machine platform base, insert set pin again, and so forth repeatable operation.Thisly change manually that to insert stepping piece mobile device degree of automation low, oil worker's labour intensity is big, efficient is low, and there is potential safety hazard in operation under big machinery.
The summary of the invention the purpose of this utility model is to provide a kind of degree of automation height, improve oil worker's service conditions, reduce labor intensity, create the working environment of highly effective and safe, improve the whole mobile device of marine rig platform base, derrick of China Petroleum equipment.
For achieving the above object, the technical scheme that the utility model is taked is: this marine rig platform base, the whole mobile device of derrick, adopt step type hydraulic power and hydraulic operation control system, the ear seat connects with derrick ear seat behind its oil cylinder, and oil cylinder vestibule seat connects with sled seat ear seat; The stepping piece connects with sled seat assembling, and it is corresponding with the hole on the slideway to have the stepping hole on the base plate of sled, and suitable with the stepping piece; Each place, angle of sled seat is provided with orienting lug.The above-mentioned mobile device of a cover is respectively installed on the left and right both sides of derrick (or base), promoting the sled seat by oil cylinder inserts in the stepping hole of sled seat base plate and slideway by the stepping piece, finish a stepwise operation, oil cylinder piston is regained then, and the upset of stepping piece is inserted in another hole, the oil cylinder piston bar is released, finish next stepwise operation, so circulation realizes that derrick (or base) is whole mobile.
Above-mentioned marine rig platform base, the whole mobile device of derrick, being primarily aimed at the marine rig platform moves in limited area, finish the drilling operation of Cong Jing, the degree of automation height, improved work efficiency, improved labor condition, guaranteed, for China's energy capital construction with go to the world to participate in the competition assurance is provided for safety in production provides equipment.
Description of drawings Fig. 1 is the front elevation of marine rig platform base, the whole mobile device of derrick;
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: the 1-derrick; 2-derrick (base) ear seat; The 3-oil cylinder; 4-sled seat ear seat; 5-stepping piece; 6-prizes seat; The 7-orienting lug; 8-derrick (base) slideway.
The specific embodiment as shown in Figure 1 and Figure 2, the marine rig platform base that the utility model provides, the whole mobile device of derrick, adopt hydraulic power and hydraulic operation control system, its oil cylinder 3 back ear seats connect with derrick ear seat 2 usefulness bearing pins, and oil cylinder 3 vestibule seats connect with sled seat ear seat 4 usefulness bearing pins; Four stepping piece 5 usefulness bearing pins connect with 6 assemblings of sled seat, and it is corresponding with the hole on the slideway 8 to have the stepping hole on the base plate of sled 6, and suitable with stepping piece 5; Four jiaos of sled seat 6 are equipped with four orienting lugs, 7 usefulness bolts and connect with sled seat 6, and the gap of assurance orienting lug 7 and slideway 8.Consistent for the position of guaranteeing to prize four stepping pieces 5 on the seat 6 with cooresponding stepping hole on the slideway, in the course of processing, pay attention to its positional precision and considered actual conditions, the hole periphery has been strengthened 5mm.In order to solve the embedding wedge phenomenon between sledge seat base plate and the slideway, the horizontal sextant angle of the axis of the axis of consideration oil cylinder 3 and sledge seat ear seat 4 in design, the grasp appropriateness guarantees to be in operation and can not scratch slideway so that increase friction force, and to 10 * 45 ° of sledge seat termination chamferings.For preventing that bearing pin from skidding off, the head of all bearing pins is fixed with safety pin, and in addition, the design of part bearing pin has butter lubricated.
With above-mentioned derrick mobile device in like manner, the step direction of drilling machine platform base and derrick 1 step direction are 90 °, thus the drilling machine platform base with same mechanism, finish with quadrat method mobile.
Weight according to derrick (base), the structure of derrick 1 is " people " font, so above-mentioned mobile device is arranged in " people " font earth plate both sides, one overlaps on one side, it is synchronously certain to require the both sides stepping to move, except that flow divider-combiner is installed in hydraulic efficiency pressure system, also require in the system each oil cylinder to operate separately.
