Description

The rotatable BOP attended operation of oil-well rig platform
Technical field
The utility model belongs to the Petroleum Machinery Industry technical field, relates to the rotatable BOP attended operation of a kind of oil-well rig platform.
Background technology
BOP attended operation platform is the vitals of oil-well rig, is used for the operation and maintenance of preventer etc.Conventional rig BOP attended operation platform is to stretch out peg in the table beam both sides to hang vertical ladder, and operating desk is adjusted high and low position by the suspension between vertical ladder, thereby realizes the operation and maintenance of preventer.But along with the continuous appearance of rig substructure new structure, base lower space structure becomes increasingly complex, and adds the variation day by day to the preventer Operation and Maintenance, and BOP attended operation platform is also had higher requirement.
Summary of the invention
The purpose of this utility model provides the rotatable BOP attended operation of a kind of oil-well rig platform, solved and had rig BOP attended operation platform unreasonable structure in the prior art, can not adapt to the orientation rotation of BOP, rig BOP attended operation platform is subjected to the problem of the spatial constraints of base bottom.
The technical scheme that the utility model adopted is, the rotatable BOP attended operation of a kind of oil-well rig platform, preventer both sides in derrick respectively are provided with a column, be connected with operating desk between every column, on the table top of operating desk railing is installed, be provided with stull and diagonal brace between these two columns, each column is connected with derrick base by pull bar, pull bar B simultaneously.
The rotatable BOP attended operation of oil-well rig of the present utility model platform, its feature also is: described pull bar, pull bar B form by the not isometrical steel pipe suit of two joints, and the suit overlapping of pull bar, pull bar B has a plurality of pin-and-holes, and pin is installed in the pin-and-hole.The two ends of described pull bar, pull bar B are provided with transfer ear, and the derrick base of each column and institute corresponding position is provided with otic placode, and each transfer ear is pegged graft with the otic placode that is connected by the pin safety pin.
The beneficial effects of the utility model are, can realize the rotation of BOP attended operation platform, are not subjected to base substructure spacial influence, and the on-the-spot applicability of rig BOP attended operation platform is strong, easy to operate, safe and reliable.

Among the figure, 1. operating desk, 2. column, 3. pull bar, 4. pull bar B, 5. drag link, 6. diagonal member, 7. railing, 8. railing B, 9. transfer ear, 10. otic placode, 11. pin safety pins, 12. pin-and-holes, 15. vertical ladders, 16. table beams, 17. pegs.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, Fig. 2, it is the structural representation of existing conventional rig BOP attended operation platform, hang vertical ladder 15 in table beam 16 both sides by peg 17, between vertical ladder 15, be connected with operating desk 1, operating desk 1 is adjusted height by the hanging position of 15 of vertical ladders, implements the operation and maintenance of preventer, if preventer turns to, operating desk 1 can't in time be adjusted angle, influences the normal use of work and other equipment.
As Fig. 3, Fig. 4, Fig. 5, the structure of device of the present utility model is, preventer both sides in derrick respectively are provided with a column 2, be connected with operating desk 1 between every column 2, railing 7 and railing B8 are installed on the table top of operating desk 1, be provided with stull 5 between these two columns 2 and diagonal brace 6 reinforces the connection, each column 2 is simultaneously by pull bar 3, pull bar B4 is connected with derrick base, pull bar 3, the two ends of pull bar B4 are provided with transfer ear 9, the derrick base of each column 2 and institute corresponding position is provided with otic placode 10, and transfer ear 9 is pegged graft with the otic placode 10 that is connected by pin safety pin 11;
Operating desk 1 is regulated high and low position according to the pin hole of differing heights position on the column 2, and operating personnel climb operating desk 1 enterprising line operate by the treadle on the column 2, railing 7, railing B8 support personnel safety.
As Fig. 8, pull bar 3, pull bar B4 forms by the not isometrical steel pipe suit of two joints, at pull bar 3, also being provided with two lugs on the pull bar B4 is to lift usefulness, pull bar 3, the suit overlapping of pull bar B4 has a plurality of pin-and-holes 12, in the pin-and-hole 12 pin is installed, when preventer rotates to an angle, the position of 4 root posts 2 changes, dislocation by pin-and-hole 12 comes adjusting yoke 3 according to field position, the socket length of pull bar B4, guarantee the tension between column 2 and base, thereby guarantee the integral body rotation of BOP attended operation platform, whole BOP attended operation platform is relatively independent, is not subjected to the restriction of structure space under the rig floor.
When the utility model device is installed, earlier 4 root posts 2 are placed in the preventer both sides, connect firm by stull 5, diagonal brace 6 between the column 2 on every limit, between column 2 and corresponding base, pull bar 3, pull bar B4 are equipped with by transfer ear 9, pin safety pin 11, otic placode 10 again, last fitting operation platform 1 and railing 7, railing B8 so far finish the installation of BOP attended operation platform.
Rotate BOP attended operation platform 1 if desired, only need stagger between pull bar 3, the pull bar B4 behind the corresponding pin-and-hole 12, reinstall bearing pin and adjust its length, see Fig. 8 according to field condition; Adjust connection angle by transfer ear 9 and bearing pin, to reach the integrally rotated requirement of BOP attended operation platform, as the state of Fig. 6, Fig. 7.
The utility model has realized that BOP attended operation platform can rotate the adjustment orientation according to the angle that preventer is put, and has improved operating efficiency in the time of safe and reliable, has broken away from BOP attended operation platform to a certain extent and has been subjected to the influence that structure space limits under the rig floor.
