Background technology
In recent years, the offshore oil exploitation scale is increasing, and oil well quantity constantly increases, and petroleum pipe line is long neglected and in disrepair to be prone to faults such as leakage, and in general, the shallow sea offshore oilfield pipeline has three kinds, and internal diameter is respectively φ 195mm, φ 247mm, φ 296mm.Offshore oilfield pipeline is carried out projects such as wall thickness, crackle when detecting using many group sonacs or leakage field sensor etc., need overcome petroleum pipe line section deformation, inwall 5mm projection or pit, cross factor affecting such as bend pipe; The number of sensors that this device is used during simultaneously owing to detection is more, and cost is higher, thus should not make the pick-up unit of serial size, so need a pick-up unit can be applicable to the detection of different-diameter petroleum pipe line.This pick-up unit is at a kind of pipe applications of diameter sometimes, but under a lot of situations pipe applications at different-diameter, both made when the pipeline with a kind of diameter uses this technology, also needed to consider the influence that manufacturing, distortion inaccuracy and the pipeline corner geometric configuration of pipeline are brought.Find by literature search, the patent of invention publication number is: 1441241, patent name is: two-way umbrella formula pipe detection diameter changing device, this patent readme is: the invention belongs to mechanical field, the axis of guide and universal coupling are fixedly connected, small box, big casing and the axis of guide are clearance fit, and fix at the axis of guide; Cramp bar one end is connected in the spill piece in small box and the big casing, and the other end connects with roller; Sensor is fixed on the sensor mount, and compression spring is arranged in the big casing; Cramp bar one end connects with small box, big casing middle concave piece, the other end connects with roller, sensor mount, cramp bar evenly distributes along the radial direction circumference, form a umbrella structure with small box, the axis of guide and pipeline, cramp bar is formed another umbrella structure with big casing, the axis of guide and pipeline.The present invention can overcome defective effects such as pipeline section distortion and inner-walls of duct projection, pit, simultaneously can be applicable to the different-diameter pipeline, the detection of pipeline can disposablely be finished, particularly under the prerequisite of not changing parts, realize detection the multiple diameter pipeline.But the signal demand of the sensor acquisition in this invention is transferred to other parts and could handles, if sensor is many, can cause signal wire to pass defectives such as shaft coupling difficulty, sealing difficulty be big, can not effectively utilize the cavity arrangements data acquisition card and the processor of casing in this invention.
Summary of the invention
The object of the invention is to overcome disadvantages of background technology, a kind of parallelogram pipe detection diameter changing device is provided, this device can be installed many group sensors, make its detection can realize detection to multiple different-diameter pipeline to pipeline, the influence that overcomes defective such as pipeline section distortion and inner-walls of duct projection, pit and cross bend pipe, and provide installing space for data acquisition card and processor at cabinets cavity.
The present invention is achieved by the following technical solutions, the present invention includes: casing, bent cramp bar, sensor mount, sensor, roller bearing, roller, straight cramp bar, extension spring, its connected mode is: one group of sensor all has been installed, the alignment probe inner-walls of duct of sensor on the sensor mount; Bent cramp bar one end is connected with casing, the other end and sensor mount, roller are connected in roller bearing jointly, the other end of sensor mount and roller, straight cramp bar are connected in roller bearing, the straight cramp bar other end is connected with casing, casing, bent cramp bar, sensor mount, straight cramp bar are formed a parallel-crank mechanism, roller bearing is the tie point of parallel-crank mechanism, extension spring one end is connected on the straight cramp bar, the other end is connected on the casing, along the circumferential direction evenly arranges many group parallel-crank mechanisms.During the extension spring tension, straight cramp bar and bent cramp bar come the sensor mount supporting, sensor mount will push with inner-walls of duct mutually by the roller with the roller bearing connection, distance between sensor and the inner-walls of duct is remained in institute's claimed range, thereby can realize detection pipeline.
Casing comprises: little end cap, little lid, spill piece, bearing pin, housing, data acquisition card and processor, big end cap, pilot sleeve, big saturating lid, installing ring, locating ring.Little end cap is fixedlyed connected with housing by screw, and the housing middle part along the circumferential direction has several holes, and the sensor lead of being convenient to be fixed on the sensor mount is incorporated into housing, is connected with processor with data acquisition card; Little lid cover, installing ring are enclosed within respectively on the axle head of little end cap, the two is a clearance fit, and on the axle head of little end cap, the axle head cross section of little end cap is " runway " shape to little lid by screw retention, end face and anchor ring junction have several trough, and an end of bent cramp bar passes from groove; Installing ring along the circumferential direction evenly has several rectangular channels, is respectively equipped with the spill piece, and bearing pin is rotationally connected an end and the spill piece of bent cramp bar, is the tie point of parallel-crank mechanism; Big end cap is fixedlyed connected with housing by screw, pilot sleeve, big saturating lid are enclosed within respectively on the axle head of big end cap, be clearance fit, the axle head cross section of big end cap is " runway " shape, cover thoroughly by screw retention on the axle head of big end cap greatly, the pilot sleeve circumferencial direction has several trough, the passing from groove of bent cramp bar, bearing pin is rotationally connected an end of straight cramp bar and the spill piece in the installing ring, also is the tie point of parallel-crank mechanism.Housing, little end cap, big end cap are formed an airtight inner chamber, and data acquisition card and processor can be installed.
The variation of parallel-crank mechanism attitude of the present invention is driven by extension spring, because the pulling force of extension spring makes the roller that is fixed in the sensor mount two ends tightly be pressed on the inner-walls of duct, thereby guaranteed that sensor mount is parallel with inner-walls of duct, satisfied the needed range finding requirement of normal operation of sensor.When running into obstacle, extension spring spurs connected straight, bent cramp bar pose and changes, and makes roller be crossed pipeline obstacle place; After cross at pipeline obstacle place, the extension spring retraction, device returns to form.When needs were measured the pipeline of other diameter, extension spring was regulated straight, bent cramp bar pose automatically, can realize significantly reducing.Because many group parallel-crank mechanism couplings are little, realize reducing separately, so each parallel-crank mechanism can be realized the reducing of subrange, integral body can realize large-scale reducing again.Cabinets cavity is empty, and data acquisition card and processor can be installed.
Compared with prior art, the present invention not only can overcome the distortion of pipeline section and the influence of inner-walls of duct projection or pit, realize the detection to multiple different-diameter pipeline, and box house can be installed data acquisition card and processor, has advantage simple and reliable for structure, convenient to operation.Reducing technology of the present invention is not only applicable to the detection of offshore oilfield pipeline, is applicable to the detection of general pipeline yet, has using value comparatively widely.
