Abstract
The invention provides a flange space relative position measuring instrument. A chassis fixed on a reference flange is equipped with a position sensor and a lens. A target flange is equipped with a photoelectric signal generator. The light emitted by the photoelectric signal generator passes through the lens and leaves a light spot on the position sensor. Through the coordinate of the light spot and a set lens center coordinate, the relative position of the target flange can be calculated. The measuring instrument has the advantages of high precision, the satisfaction of middle and short distance detection and high reliability.
Description
Technical field
The present invention relates to measuring instrument, particularly relate to a kind of measuring instrument of measuring flange relative position spatially.
Background technology
Flange often applies to pipeline and connects, and particularly, in the field engineering of large-scale pipeline, the connection of two sections of pipeline sections all links into an integrated entity by flange.And if two sections of fixing pipeline sections to be linked together, also need the pipeline section of prefabricated length-specific and shape, by prefabricated pipeline section two ends, connect respectively the fixing pipeline section in two ends and realize and being communicated with.The prefabricated of pipeline section need to be measured two sections of fixedly distances of pipeline section, measures the distance of flange at the mouth of pipe place of pipeline section.
Existing measuring equipment has two kinds, and a kind of is measurement mechanism for laying compared with long pipe runs such as seabed, and principle is to survey level orientation and relative height angle with protractor, with wire rope range finding from, this equipment belongs to pure mechanical measuring device.Another kind also has electronic computing device except protractor and wire rope, the measurement data of protractor is inputted to electronic equipment by resolver-to-angle converter, the length of wire rope is also inputted to electronic equipment simultaneously, Azimuth & Range is combined by corresponding software and processes the making drawing that just can obtain mounting pipe, and this device belongs to dynamo-electric hybrid measurement equipment.Above two kinds of measurement mechanisms all can be measured pipeline section, but the pure mechanical measuring device of the first can only be for larger distance, as more than tens meters, and the occasion that accuracy requirement is not too high, and in short distance, higher next cannot being competent at of situation of accuracy requirement; The dynamo-electric measurement mechanism mixing of the second, angular error is generally all in 0.5o, therefore as measuring distance reaches three meters, measured value can reach the deviation of 22mm, can meet in the situation that short distance, accuracy requirement are general and use, but be difficult to reach requirement in short-distance and medium-distance (in as ten meters), occasion that precision prescribed is higher, and the parts that this kind of device need to be brought measure field into are more, if any measuring base, measuring mechanism, data processing computer and stube cable etc., its operation is comparatively complicated.Also have, two kinds of above measurement mechanisms include mechanical activity part, due to mechanical relative motion and wearing and tearing, on precision and reliability, all can have impact.
Summary of the invention
The present invention aims to provide a kind of measuring instrument of accurately measuring flanged pipeline section relative position in short-distance and medium-distance, to improve the accuracy of measurement and the accuracy that prefabricated tube section is made.
Flange relative space position measuring instrument of the present invention, comprise the cabinet being fixed on benchmark flange, two position transducers are housed in cabinet, and the signal receiving plane of two positions sensor is positioned at same plane and its top is equipped with lens, and two lens are positioned at same plane; Have and send position signalling to the photo-generator of position transducer, photo-generator is arranged on the flange bolt hole place of tested target flange.
Flange relative space position measuring instrument of the present invention, cabinet is placed on to monitoring point, photo-generator is placed on the flange bolt hole place of tested flange, during work, photo-generator emits beam, rays pass through lens leaves hot spot respectively on two position transducers, obtain the coordinate points of two hot spots, and the intrinsic parameter that the coordinate of lens center is instrument, 2 of hot spot on relative position transducer and the central points of lens are in line, the joining of two straight lines is the coordinate points of photo-generator, it is the coordinate points of target flange bolt hole, obtain thus three groups and above data and just can calculate the relative position of flange.This measuring instrument is photoelectric measurement instrument, has high measuring accuracy, and the error in short-distance and medium-distance is extremely low, greatly improves the accuracy of measurement and the accuracy that prefabricated tube section is made; This measuring instrument machinery-free moving component, still can remain on high precision after long-time use, guarantees the reliability of measuring.
Accompanying drawing explanation
Fig. 1, the 2nd, the structural representation of flange relative space position measuring instrument.
Fig. 3-5th, the partial enlarged drawing of the relative space position of flange shown in Fig. 1 measuring instrument.
Embodiment
A kind of flange relative space position measuring instrument, comprise the cabinet 1 being fixed on benchmark flange 101, two position transducers 2 are housed in cabinet 1, and the signal receiving plane of two positions sensor 2 is positioned at same plane and its top and is equipped with lens 3, two lens 3 and is positioned at same plane; Have and send position signalling to the photo-generator 4 of position transducer 2, photo-generator 4 is arranged on the flange bolt hole place of tested target flange 102.
Photo-generator is arranged on the flange bolt hole place of target flange, its coordinate is A, rays pass through lens leaves hot spot respectively on two position transducers, obtain the coordinate points A1 of two hot spots, A2, and the intrinsic parameter that the coordinate of lens center is instrument, be respectively O1, O2, 2 of hot spot on relative position transducer and the central points of lens are in line, two straight line A1-O1, the joining of A2-O2 is the coordinate points A of photo-generator, it is the coordinate points of target flange hole, thus can be by known coordinate points A1, A2, O1, O2 calculates the coordinate of A, obtain thus three groups and above data and just can draw the relative position of flange.This measuring instrument has high precision, the flange relative position in energy Measurement accuracy short-distance and medium-distance.
Cabinet 1 comprises the casing 11 that position transducer 2 and lens 3 are housed, with the guide rail 12 for casing location, on casing 11, have the guide groove 13 matching with guide rail 12, guide rail 12 can slide in the guide groove of casing 11, also have two guide rail 12 is fixed on to the set bolt 14 on casing 11, on casing 11, two bolts hole 15 that match with two set bolts 14 are respectively arranged on the same diameter of benchmark flange.Before measurement, by guide rail and guide groove, adjust cabinet position, set up the direction of resolving coordinate system, it is more accurate to make to measure.
The lens over cap 5 of protection lens 3 is removably housed on cabinet 1; During work, over cap is pulled down and can be carried out surveying work, and because of easy impaired the scratching of lens, under off working state, can to lens, protect with over cap.
Usb data interface is housed on cabinet, can passes through this interface connection data line and computing machine, be convenient to the transmission of data; On cabinet, also can install wireless signal sending and receiving device, utilize transmission of wireless signals data; Computing machine or single-chip microcomputer, storer, power supply can also be integrated in to cabinet inside, touch-screen be set for operation on cabinet, can convenient operation and transportation, and reduce the needs of utility appliance.
