Embodiment one:
As shown in Figure 1, the utility model embodiment one provides a kind of jacking apparatus, including at least two lifting bodies, Lifting body is used for the below the crossbeam for being separately positioned on drillingrig base;Lifting body includes stent and the liquid being arranged on above stent Press jack.
In concrete operations, jacking apparatus can be arranged on below the cantilever beam rig floor of drilling platforms;Jacking apparatus is adjusted, is made It jacks up rig floor, and rig floor is departed from cantilever beam;When rig floor departs from cantilever beam to pre-determined distance, stop jacking apparatus operation, Maintenance cantilever beam.
Compared with the prior art, the application can by the setting of above-mentioned jacking apparatus, rig floor can effectively be jacked up and with Cantilever beam completely disengages, to eliminate rig floor dead weight to the influence caused by cantilever beam maintenance, to avoid rig floor of the prior art And the shifting of hanging of derrick operates, the work such as rig floor cable, pipeline, the dismounting of equipment, time dress, debugging also can be effectively avoided, can So that the maintenance operation of cantilever beam is simple and practicable, it is time saving and energy saving;Meanwhile the large-scale use for hanging moving device can be also avoided, can Effectively reduce operating cost.
In the present embodiment, above-mentioned jacking apparatus includes two lifting bodies, and two lifting bodies are separately positioned on rig floor bottom Two below the crossbeams of seat;Lifting body includes stent and the hydraulic jack being arranged on above stent.
In concrete operations, above-mentioned post rod mechanism can be symmetrically arranged on to two below the crossbeams of drillingrig base, effectively protected The producing balanced forces of rig floor are demonstrate,proved, and then can effectively ensure that being smoothed out for maintenance operation, can effectively be overcome because of rig floor stress not Stable Defects caused by.
As shown in Figure 2-5, in the present embodiment, above-mentioned stent includes being arranged on the rectangle truss 1 of bottom, is arranged on centre Triangular truss 2 and the column 3 for being arranged on top;Column 3 includes at least two shaped steel being vertically arranged, and the top of shaped steel is equal Mounting platform 4 is provided with, the first hydraulic jack 5 and the second hydraulic jack 6 are both provided with mounting platform 4.
In concrete operations, the setting of above-mentioned rectangle truss 1 can be passed through, using the teaching of the invention it is possible to provide relatively stable lower support structure; The parts such as the pipeline of rig floor bottom can effectively be avoided by the setting of above-mentioned top upright post 3 in operation;Can be by upper State the setting of mounting platform 4, using the teaching of the invention it is possible to provide the mounting platform 4 relatively stable to hydraulic jack, to meet its installation requirements;Can By the setting of above-mentioned triangular truss 2, being stably connected between rectangle truss 1 and column 3, above-mentioned triangle purlin can be realized The setting of frame 2, also can effectively avoid the pipeline of rig floor bottom to a certain extent, can ensure that the jacking operation of rig floor is smooth Carry out.
In the present embodiment, jacking apparatus is adjusted, it is jacked up rig floor, and rig floor is departed from cantilever beam;It can specifically use such as Lower step:
Step 1:The first hydraulic jack 5 boosting adjusted at the same time on all mounting platforms 4 jacks up preset height h, in institute The lower section for having the second hydraulic jack 6 sets the backing plate of increase height h, so that the top of the second hydraulic jack 6 and the first liquid The top of pressure jack 5 flushes.
Step 2:After step 1 is completed, adjust all boostings of second hydraulic jack 6 and jack up preset height h, adjust all First hydraulic jack, 5 pressure release restPoses, and increases the backing plate of height 2h in the lower section of all first hydraulic jacks 5, So that the top of the first hydraulic jack 5 is flushed with the top of the second hydraulic jack 6.
Step 3:After step 2 is completed, adjust all boostings of first hydraulic jack 5 and jack up preset height h, adjust all Second hydraulic jack, 6 pressure release restPoses, and increases the backing plate of height 2h in the lower section of all second hydraulic jacks 6, So that the top of the second hydraulic jack 6 is flushed with the top of the first hydraulic jack 5;Repeat step 2.
In concrete operations, above-mentioned steps 1,2,3, which may make up, alternately adjusts operation, i.e., adjusts the first hydraulic jack 5 in turn And second hydraulic jack 6, above-mentioned preset height h can be the maximum of the first hydraulic jack 5 and the second hydraulic jack 6 Range;By the above-mentioned operation for alternately adjusting hydraulic jack, can effectively overcome caused by hydraulic jack maximum range Limitation, by the application of tie spacer, can realize the adjusting operation of different height so that rig floor depart from cantilever beam to it is default away from From.
In the present embodiment, the original state of above-mentioned first hydraulic jack, 5 and second hydraulic jack 6, is respectively provided with initial Pressure value p, p > 0.
In the present embodiment, above-mentioned steps 3 further include:
Step c1:When rig floor departs from cantilever beam pre-determined distance m, adjust all hydraulic jacks in pressure-increasning state and let out Pressure restPoses, and removes the hydraulic jack and backing plate below;
Step c2:The steel pipe of height m is arranged between mounting platform 4 and the crossbeam of rig floor, and with mounting platform 4 with it is horizontal It is welded to connect between beam;
Step c3:Remaining hydraulic jack pressure release is adjusted, removes the hydraulic jack and backing plate below.
In concrete operations, above-mentioned pre-determined distance is 100mm;That is, when rig floor departs from cantilever beam 100mm, stop adjusting behaviour Make, and carry out corresponding fixed operation;At this time, one in the first hydraulic jack 5 or the second hydraulic jack 6 is in boosting State, another is in original state;It may be selected, by the hydraulic jack pressure release in pressure-increasning state, to be now in original state Hydraulic jack be used to support rig floor.
And then all remove the backing plate of the hydraulic jack after pressure release and lower section, and the steel pipe of 100mm high is set Between mounting platform 4 and the crossbeam of rig floor, and it will be welded to connect between steel pipe and mounting platform 4 and crossbeam;Finally, then will be surplus Remaining hydraulic jack pressure release, i.e., release the initial pressure of hydraulic jack, so that the total weight of steel pipe support rig floor;It is surplus After the initial pressure of remaining hydraulic jack releases, hydraulic jack is in free state, directly takes out.
, can be according to it should be noted that, it is necessary to when rig floor is dropped to initial position after the completion of cantilever beam maintenance operation The reverse sequence of above-mentioned erection sequence carries out, until rig floor is fallen after rise to initial position.
