Description
Technical field
The utility model belongs to oil-well rig equipment control technology field, relates to a kind of drilling line that utilizes and realizes the device that the oil-well rig Jackup mast hoists.
Background technology
At present, the lifting method of oil-well rig Jackup mast is: after the integral installation of derrick low level, the large rope of derrick lifting is installed, big lifting rope forms rope system between derrick man-like shelf and derrick, utilize winch power by rig swim crane system (overhead traveling crane tourist bus) traction big lifting rope drag rope system by the derrick integral lifting to vertical duty.The method has the following disadvantages: 1) due to the stroke of trip crane system, be subject to the restriction of clear derrick height, effectively the rope number is less in rope system, so the suffered pulling force of big lifting rope is larger, and the big lifting rope wirerope diameter is thicker, and diameter of pulley is larger; 2) on derrick, big lifting rope application point place is stressed more concentrated, therefore need to do structural strengthening, causes derrick weight to increase; 3) big lifting rope is the high strength specialized wire rope, and price is more expensive, increases cost of investment; 4) due to big lifting rope after putting in place at derrick lifting all in a high position, maintaining is wasted time and energy, and strengthens labor strength; 5) when the cluster well drillng operation, big lifting rope is exposed in adverse circumstances always, larger on the life-span impact of big lifting rope.
The utility model content
The purpose of this utility model is to provide a kind of drilling line that utilizes and realizes the device that the oil-well rig Jackup mast hoists, and has solved structure in the prior art problem unreasonable, that use is inconvenient, maintaining is wasted time and energy, labour intensity is large is set.
The technical scheme that the utility model adopts is, a kind of drilling line that utilizes is realized the device that the oil-well rig Jackup mast hoists, be provided with the fast rope sheave of overhead traveling crane on the overhead traveling crane on derrick top, at the derrick rear side, near the overhead traveling crane place, the upper left assembly pulley of derrick, the upper right assembly pulley of derrick be installed respectively; Be separately installed with the left assembly pulley of derrick, the right assembly pulley of derrick on the girder of both sides, derrick middle part; In the derrick bottom, dead line anchor is installed;
Be separately installed with man-like shelf left chain wheel group, man-like shelf right pulley group at the top of Zuoren cabinet frame, right man-like shelf;
Winch is installed on base, and described wire rope wire rope handling method as requested is connected to winch successively from dead line anchor.
The beneficial effects of the utility model are: utilize boring winch power, adopt the drilling line of boring winch as raising line, the method for the effective rope number that is by increase derrick lifting rope, reduce the every pulling force that hoist rope is suffered, realizes hoisting of derrick; Overcome the deficiency of utilizing big lifting rope derrick telescoping method, simple in structure, maintaining is convenient, has alleviated construction weight, has reduced investment cost.
Compared with prior art, every cover derrick can be saved a set of big lifting rope to the utility model; Simultaneously, due to the variation of stress point, can reduce derrick lifting load; Owing to there is no independent big lifting rope, maintaining is exactly the maintaining of drilling line itself, can reduce the maintaining to hoist rope.
The accompanying drawing explanation
The front view that Fig. 1 is the utility model device (before the lifting of ground);
The top view that Fig. 2 is the utility model device (before the lifting of ground).
In figure, 1 Zuoren cabinet frame, 2 right man-like shelves, 3 man-like shelf left chain wheel groups, 4 man-like shelf right pulley groups, the left assembly pulley of 5 derrick, the right assembly pulley of 6 derrick, the upper left assembly pulley of 7 derrick, the upper right assembly pulley of 8 derrick, 9 winches, 10 dead line anchors, 11 derricks, 12 drilling lines, 13 overhead traveling cranes, the fast rope sheave of 14 overhead traveling crane.
The specific embodiment
With reference to Fig. 1, Fig. 2, the structure of utilizing drilling line to realize the device that the oil-well rig Jackup mast hoists of the present utility model is: comprise Zuoren cabinet frame 1, right man-like shelf 2, man-like shelf left chain wheel group 3, man-like shelf right pulley group 4, the left assembly pulley 5 of derrick, the right assembly pulley 6 of derrick, the upper left assembly pulley 7 of derrick, the upper right assembly pulley 8 of derrick, winch 9, dead line anchor 10, derrick 11, drilling line 12, overhead traveling crane 13, the fast rope sheave 14 of overhead traveling crane
On derrick 11 tops, overhead traveling crane 13 is installed, is provided with the fast rope sheave 14 of overhead traveling crane on overhead traveling crane 13, at derrick 11 rear sides, near overhead traveling crane 13 places, the upper left assembly pulley 7 of derrick, the upper right assembly pulley 8 of derrick are installed respectively; Be separately installed with the left assembly pulley 5 of derrick, the right assembly pulley 6 of derrick on the girder of both sides, derrick middle part; According to design attitude, dead line anchor 10 is installed in the derrick bottom;
Be separately installed with man-like shelf left chain wheel group 3, man-like shelf right pulley group 4 at the top of Zuoren cabinet frame 1, right man-like shelf 2; According to designing requirement, winch 9 is installed on base; Described assembly pulley middle pulley quantity specifically determines according to the derrick lifting magnitude of load, wire rope wire rope handling method as requested successively from dead line anchor 10 out, through after each assembly pulley, finally be connected on winch 9.
The preferred a kind of wire rope handling route of the utility model device is, the upper right assembly pulley 8 → winch 9 of the left assembly pulley 5 → man-like shelf of the fast rope sheave 14 → man-like shelf of the overhead traveling crane on dead line anchor 10 → overhead traveling crane 13 left chain wheel group 3 → derrick left chain wheel group 3 → derrick left assembly pulley 5 → man-like shelf left chain wheel group 3 → derrick upper left assembly pulley 7 → man-like shelf right pulley group 4 → derrick right assembly pulley 6 → man-like shelf right pulley group 4 → derrick right assembly pulley 6 → man-like shelf right pulley group 4 → derrick.
The course of work of the utility model device is:
1) when derrick need to hoist, the wire rope handling mode of drilling line 12 is: then the upper right assembly pulley 8 → winch 9 of the left assembly pulley 5 → man-like shelf of the fast rope sheave 14 → man-like shelf of the overhead traveling crane on overhead traveling crane 13 left chain wheel group 3 → derrick left chain wheel group 3 → derrick left assembly pulley 5 → man-like shelf left chain wheel group 3 → derrick upper left assembly pulley 7 → man-like shelf right pulley group 4 → derrick right assembly pulley 6 → man-like shelf right pulley group 4 → derrick right assembly pulley 6 → man-like shelf right pulley group 4 → derrick is fixed on drilling line on winch drum.After being wound around enough drilling lines by cylinder, the other end of drilling line (the fast rope sheave 14 of overhead traveling crane is to dead line anchor 10) is fixed on dead line anchor 10, cylinder by winch 9 rotates, and is wound around drilling line 12, can be by derrick lifting to stand up position.
After having hoisted, regain all drilling lines 12, then according to normal drillng operation, put on drilling line and get final product.
2) in the time of need to transferring derrick: process is contrary with above step.
