Description
Technical field
The utility model relates to a kind of gathering pipe field measurement apparatus based on laser ranging technique, is applied to the processing and manufacturing of gathering pipe.
Background technology
During modern ships manufactures, place has all been paved with pipeline, and a series of operations such as the design of these pipe fittings, manufacture and the inspection after in board installing are referred to as " pipeline laying ".Usual boats and ships are sectional constructions, and the pipeline intersegmental in the segment folding time-division just needs gathering pipe to connect, but rely on pipeline design drawing to produce gathering pipe miscellaneous, and the making of gathering pipe adopts usually gets type method and site welding connection.
The most difficult in pipeline makes is " ensureing the precision that finished product is good ".But it is incorrect to adopt two kinds of methods above often to there will be the gathering pipe flange bolt empty position produced, situation about cannot install is caused to occur.There is the shortcomings that efficiency is low, waste of material serious and machining precision is not high in these two kinds of methods.At present, the states such as Japan and Korea S develop closed tube reproduction system for the problems referred to above, the locus feature of the flange of gathering pipe is treated by tactful machine in-site measurement two, then this locus feature is simulated by special fitting software, and export controling parameters, coordinate special three-dimensional positioner can reproduce the position feature of two flanges, the gathering pipe manufactured is lifted on reproduction machine and can produces free from error gathering pipe with flange welding.What wherein measuring equipment adopted is single stay cord measuring machine with two angular transducers and a linear transducer, and its cardinal principle uniquely can determine a point in spheric coordinate system two angles specified and a length.Therefore, the position mark of unique point in the coordinate system of specifying on flange can be measured by this measuring machine.But the weak point of this kind of measuring method needs repeatedly to adjust the position of rope outlet when being and measuring, to ensure that stay cord is linear state, this operating process is loaded down with trivial details.For solving this kind of present situation, develop closed tube reproduction system 201110309478.9, the locus feature of the flange of gathering pipe is treated by measuring machine in-site measurement two, then this locus feature is simulated by special fitting software, and export controling parameters, coordinate special three-dimensional positioner can reproduce the position feature of two flanges, the gathering pipe manufactured is lifted on reproduction machine and can produces free from error gathering pipe with flange welding.For obtaining the characteristic parameter treating the flange of gathering pipe, Three-Coordinate Measuring Arm is adopted also to be feasible scheme, this gage beam is connected in series by 6 rotary joints by 6 arms rotated and 1 measuring head, in each joint, angled scrambler is installed, one section of gage beam is fixed on pedestal, irremovable in measuring process, and measuring head can move at space free, form one and close spherical measurement space, each joint rotation angle and component corner is obtained by the optoelectronic angle scrambler being arranged on each joint and rod member inside, at the brachium in conjunction with each joint arm, interarticular angle etc., apply coordinate model thus the three-dimensional coordinate position of acquisition measured point.Use the characteristic parameter of gage beam measurement flange very convenient, only need to get a little at feature locations, then namely required characteristic parameter is calculated by software, and these characteristic parameters need not be known in advance, but the limited length of this gage beam and the expensive of gage beam, each joint of external pelivimetry arm is all weak link, if in use collide, very easily damages.The ultimate principle of the gathering pipe measuring machine in 201110323558.X adopts three pulling rope length sensors in triangle distribution as measuring original paper, under Descartes's rectangular coordinate system, go out fag end as spherical equation using three pulling rope length sensors, treated the spherical co-ordinate of the locus of gathering pipe flange by high-precision measuring equipment subsidiary.Owing to there is certain gap between stay cord and stay cord head, ensure that stay cord can pull out smoothly, thus cause stay cord head to produce small deviation as the axial centerline of the centre of sphere, make the locus of gathering pipe to be measured produce deviation; And due to the permanent stay cord effect of stay cord, the elastic telescopic of stay cord causes the precision of closing up greatly to reduce, and stay cord generation wearing and tearing cause the damage of stay cord, the performance that impact is measured and work efficiency and increase the input of cost, research and develop for this reason a kind of more simple, measuring accuracy is higher and the portable gathering pipe measuring method that is not easily disturbed and device are that pipeline manufacturing enterprise and installation enterprises are happy to expectation.
