A ground beam of the device has a truss structure, the upper plane has no bulges, and two hydraulic cylinders are horizontally arranged in the ground beam and connected with the ground beam; a pull beam has a box body structure, the upper part of the pull beam is connected with a connecting rod, and the lower part of the pull beam is connected with the two hydraulic cylinders respectively; a ridge spar sits on a rotating disk beam, and the lower end of the ridge spar is connected with the connecting rod; and the lower end of a lifting ring is connected with the ridge spar, and the upper end of the lifting ring is connected with an idler car. By adopting the device, the headframe and the base of the drilling machine do not need to be separated for performing the tensile testing, and the uniform stress on the lower plane of a main beam of the base can be ensured. Furthermore, the deficiencies that the existing tensile testing device for the drilling machine performs the tensile testing on the headframe and the base separately, and the stress on the lower plane of the main beam of the base is non-uniform.
Description
Technical field:
The utility model relates to a kind of oil-well rig detection technique field, and particularly a kind of 5000m, 7000 meters, 9000 meters different model rigs of being applicable to are done the device of derrick, base tensile test.
Background technology:
The tensile test that the conventional rig pulling experiment device that uses is derrick, base is separately done, and base girder lower plane unbalance stress, adopts four jacking hydraulic cylinders to bring to Front on the table beam, and complicated operation has carelessness slightly, and hydraulic cylinder can fly out, and is absolutely unsafe.
The utility model content:
The technical problems to be solved in the utility model provides a kind of oil-well rig pull force tester, and this device has realized need not separately to do the tensile test of drilling derrick, base, guarantees that base girder lower plane is evenly stressed.The tensile test that to have overcome existing rig pulling experiment device be derrick, base is separately done, and the deficiency of base girder lower plane unbalance stress.
Technical solution adopted in the utility model is: a kind of oil-well rig pull force tester, form by tourist bus, suspension ring, Tian Liang, table beam, connecting rod, straining beam, hydraulic cylinder and grade beam; Grade beam is a truss-frame structure, and last plane does not have protrusion, and two hydraulic cylinders are horizontally-arranged to link to each other in grade beam and with grade beam; Straining beam is a body structure, and top is connected with connecting rod, and the bottom is connected with two hydraulic cylinders respectively; It beam is seated on the table beam, and the lower end is connected with connecting rod; The suspension ring lower end links to each other with the sky beam, and the upper end links to each other with tourist bus.
The beneficial effects of the utility model are: the utility model is a truss-frame structure owing to having adopted grade beam, two hydraulic cylinders are horizontally-arranged to link to each other in grade beam and with grade beam, the suspension ring lower end links to each other with the sky beam, the mode that the upper end links to each other with tourist bus, thereby has a tensile test of using same set of checkout equipment to do drilling derrick, base, the function that need not separately to do experiment guarantees that base girder lower plane is evenly stressed.In addition, the utility model is simple in structure, and is easy to operate, safe and reliable, guarantees personal safety to greatest extent, and maintaining is convenient.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in drawings, a kind of oil-well rig pull force tester is made up of tourist bus 1, suspension ring 2, day beam 3, table beam 4, connecting rod 5, straining beam 6, hydraulic cylinder 7 and grade beam 8; Grade beam 8 is a truss-frame structure, and last plane does not have protrusion, and warranty test levelling of the land at ordinary times is maximum with the useful area that is contacted by the test rig substructure in not exceeding the truss-frame structure width range, make reacting force evenly stressed in the base girder.Two hydraulic cylinders 7 are horizontally-arranged to link to each other in grade beam 8 and with grade beam 8, mentions hydraulic cylinder 7 during test, and this structure has effectively reduced the ground trench depth, is convenient to draining and handles.Straining beam 6 is a body structure, and top is connected with connecting rod 5, and the bottom is connected easy accessibility with two hydraulic cylinders 7 respectively.It beam 3 is seated on the table beam 4, is the pulling force transfer point of doing derrick and base test.They beam 3 lower ends are connected with connecting rod 5, and the base load test is uneven in length with 5 two on connecting rod, and short part is used for the 5000m rig, and long part is used for 7000 meters and 9000 meters rigs, and the many usefulness of a device are economical and practical; Suspension ring 2 lower ends link to each other with sky beam 3, and the upper end links to each other with tourist bus 1.
Hydraulic power system mainly is made up of Hydraulic Station, hydraulic cylinder 7, hydraulic control system etc.Two hydraulic cylinders 7 provide hydraulic power by same hydraulic power source, and two hydraulic cylinders 7 are synchronous, also can operate separately; 7 interlockings of two cover hydraulic cylinders, warranty test safety; Test pressure is fine-tuning, intuitively shows test pressure and pulling force.Away from hydraulic power source, hydraulic control valve gets final product on the operate ground when doing experiment, and ensures operating personnel's personal safety to greatest extent.Test pressure can arbitrarily be controlled by operating personnel, can accomplish in the voltage stabilizing of specified testing pressure value.Hydraulic operating system is by the accurate distribution valve uniform distribution of flow, and two hydraulic cylinder 7 pulling force unanimities guarantee that to greatest extent two hydraulic cylinders 7 are stressed even.Also but hydraulic cylinder 7 is controlled in manual operation respectively simultaneously, adjusts the problem of hydraulic cylinder 7 pulling force inequalities.
In the utility model when work,, the grade beam 8 that two hydraulic cylinders 7 and assembly welding is good is connected with two bearing pins respectively, and insertion shear-pin and safety pin in the grade beam 8 that then hydraulic cylinder 7 crouched, make on the grade beam 8 the plane maintenance smooth.Grade beam 8 is inserted in the trench of laying a solid foundation, and two end bearings and intermediate pads are landed, and girder is unsettled.Rigging up derrick and base, the centering well head aligns itself and tensile test platform center.Mention one of them hydraulic cylinder 7, be connected with straining beam 6 respective side with a bearing pin, straining beam 6 tops are connected with connecting rod 5, mention connecting rod 5 then and insert table beam 4 inboards, simultaneously straining beam 6 are connected with another hydraulic cylinder 7.Sky beam 3 is placed on plane on the table beam 4 by position shown in Figure 1, links to each other with connecting rod 5 usefulness bearing pins down.The primer fluid potential source, tension hydraulic cylinder 7 carries out hydraulic system debugging.It beam 3, grade beam 8 and well head centering.The primer fluid potential source, tension hydraulic cylinder 7 is done the base tensile test, pauses at different pulling force points, observes table beam 4, base and ambient stress value, and record.Slowly pressure release is to zero condition.Pull force tester is motionless, and suspension ring 2 times are linked to each other with sky beam 3, goes up to link to each other with tourist bus 1.Start main winch, mention suspension ring 2, when slowly stretching out hydraulic cylinder 7 to stroke 550mm simultaneously, tension main winch wire rope, main winch is braking state, and tension hydraulic cylinder 7 pauses at different pulling force points, observes derrick, base and ambient stress value, and record.Slowly pressure release is to zero condition.
