Description
technical field
The utility model relates to the charger technical field of in oil exploration & development, the load-bearing capacity of derrick being tested.
Background technology
Oil-well rig boring tower is the visual plant in oil exploration & development process, and its security performance is directly connected to the safety in production of a whole set of borer system.At present the safety evaluation of drilling derrick is mainly adopted to finite element method and the drilling derrick load carrying capacity test method based on model correction.
If publication number is CN102288401A, the Chinese patent literature that open day is on Dec 21st, 2011 discloses a kind of method of testing of carrying capacity of oil derrick, and model forms the material property database of the structure of oil derrick main body; Set up the library of cross section of the structure that forms oil derrick main body; The Design of Main Structure figure of the oil derrick of the need of take test is source, sets up the 3D model of this oil derrick agent structure; Then the oil derrick of need test is successively subjected to visual examination and is accurately measured; According to test result, to setting up 3D model, revise; Based on revised oil derrick model, adopt finite element software ANSYS to evaluate the load-bearing capacity of oil derrick.This method of testing does not affect petroleum drilling and mining operation, the not impact of climate, surrounding devices, can predict real-time and accurately in the load-bearing capacity with oil derrick, having broken away from the restriction of natural environmental condition, is a kind of round-the-clock, method of testing on site work without carrying capacity of oil derrick impact, fast and reliable.
Above-mentioned finite element method needs a large amount of derrick geometry actual parameter information, has larger difficulty, the less application of Practical Project in practice.Drilling derrick load carrying capacity test refers to derrick is carried out to a directly scientific experimentation job of test.Its objective is by load test, understand the practical working situation of derrick under test load effect, determine derrick safe bearing capacity and service condition; In addition, for some, in finite element analysis, be difficult to the position of calculating, also can reach the object that is directly acquainted with its stress by test.Derrick geometry test also contributes to find indiscoverable hidden danger in general inspection, can check design and the workmanship of derrick geometry.Therefore, the method that derrick geometry is tested, is commonly the actual derrick safety evaluation of engineering and adopts.Derrick geometry test, by the character of test load, can be divided into two kinds of static method test and dynamic method tests.Static method test refers to static load, for example, slowly to promote the load of specifying load-carrying drilling tool, or static strain, the off-position of to apply load-carrying on derrick hook, measuring structure such as move at the pilot project, static characteristic parameter to derrick geometry provides measured data, the static design of verification structure, thereby duty and the ability to work thereof of judgement derrick geometry; Dynamic method test refers to by various modern measurement means, to causing the dynamic loading reaction of derrick vibration, test, to obtain the kinetic parameter of derrick geometry, the dynamic design of checking structure, thereby duty and the ability to work thereof of evaluation derrick geometry.Two kinds of test methods are compared, because dynamic method test need to obtain derrick geometry kinetic parameter by test data analysis, indirectly derive again duty and the load-bearing capacity of derrick, test parameters is affected by environment larger, and the reliability of test findings is far below slow test.Therefore, drilling derrick safety assessment slow test method, is appraisal procedure the most reliably at present, and is adopted by related specifications.
Derrick static(al) test secundum legem, needs at least 25% design maximum load.For the derrick newly dispatching from the factory, in manufacturing plant, can provide test load by earth anchor, and for the drilling derrick having come into operation, depend on and utilize the weight of drilling tool as test load, need the operating modes to be detected such as passive, and for some special circumstances, such as, ocean gas production platform derrick, because drilling operation is less, cannot provide the weight of drilling tool as test load.During drilling derrick safety assessment, often running into drilling derrick cannot operation because of assessment not, cannot operation just can not provide assessment to test the phenomenon of load.
In sum, adopt the scheme of above-mentioned prior art, test load need to be provided, wasted the time in actual use, need the operating modes to be tested such as passive, and can not when derrick no operatton, to derrick, carry out static(al) test.
Summary of the invention
The utility model is intended to for the existing defect of above-mentioned prior art and deficiency, a kind of derrick capacity loading device for testing is provided, use the utility model, without drilling tool, provide test load, thereby avoided the situation of the operating mode to be tested such as passive, can when derrick no operatton, to derrick, carry out static(al) test easily.
The utility model is by adopting following technical proposals to realize:
A kind of derrick capacity loading device for testing, it is characterized in that: comprise two sections of joist steel or channel-section steels side by side, between two joist steel side by side or channel-section steel, through board-type steel, connect, described board-type steel be shaped as rectangle, board-type steel is an integral body by 1-4 bar joist steel or channel-section steel welding, joist steel side by side of board-type steel and two or channel-section steel be integrally formed is shaped as T shape, in the epimere symmetria bilateralis of board-type steel, is provided with a pair of hanger, is fixedly installed and loads steel axle above hanger.
At the hypomere of board-type steel and joist steel or channel-section steel junction, be provided with reinforcement gusset.
Described reinforcement gusset is the angle steel that is shaped as square.
The number of described reinforcement gusset is eight, strengthens gusset and is symmetricly set on board-type steel.
At the hypomere of described board-type steel and joist steel or channel-section steel junction, be provided with anti-fall otic placode.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, adopt two sections of joist steel or channel-section steels side by side, be combined with board-type steel and form whole T-shaped loading device for testing, when work, by charger placing rotary disk central lower; Use air hoist or hydraulic wireline winch, device is slowly promoted to derrick support table beam lower end, charger contacts with table beam; Suspension ring are connected with " loading steel axle "; Slowly promote again hook block and apply test load.By such frame mode, without drilling tool, provide test load, thereby avoided the situation of the operating mode to be tested such as passive, can when derrick no operatton, to derrick, carry out static(al) test easily.
2, in the utility model, at the hypomere of board-type steel and joist steel or channel-section steel junction, be provided with reinforcement gusset, strengthen the set-up mode of gusset, increased board-type steel and the joist steel of bottom or the connection reliability of channel-section steel,
