Specific embodiment

The utility model is described in further detail with attached drawing combined with specific embodiments below.

The long bend pipe cubing of the utility model as shown in Figure 1:, including as each detection part common carrier bottom plate 1 and Benchmark pipe end positioning component 2, standard inspection block 3, tail pipe detection components 4 and measuring basis block 5.Wherein, measuring basis block 5 is distributed in On bottom plate 1, for establishing space coordinates in three-dimensional coordinates measurement.Benchmark pipe end positioning component 2 and tail pipe detection components 4 are distinguished Be mounted on the both ends of bottom plate 1, standard examine block 3 be it is multiple, be set to benchmark pipe end positioning component 2 and tail pipe along each section of long bend pipe Between detection components 4, for examining corresponding position degree.Connection inspection cylinder on benchmark pipe end positioning component 2 and tail pipe detection components 4 6, it examines and is provided with tolerance slot on cylinder 6, and the variation of drawing tolerance, operation side can be adapted to by replacing the inspection cylinder of different tolerance slots Just.Tolerance slot on 2 one end of benchmark pipe end positioning component inspection cylinder 6 is for detecting prover pipe end face squareness, tail pipe detection components 4 Tolerance slot on one end inspection cylinder 6 is for detecting tail pipe end surface inclination.

Specifically, benchmark pipe end positioning component 2 and tail pipe detection components 4 include ball guide post 7, benchmark baffle 8, benchmark Blade 9, driving handle 10 and uniaxial guiding vertical plate 11.One end of ball guide post 7 be mounted in uniaxial guiding vertical plate 11 and with drive Fixed handle 10 is connected, the other end connection inspection cylinder 6 of ball guide post 7；Benchmark blade 9 is set to driving handle 10 and uniaxial guiding is vertical Between plate 11；Benchmark baffle 8 is fixed on the side wall of uniaxial guiding vertical plate 11, is provided on benchmark baffle 8 and is placed benchmark blade 9 Slot 12, the width of the slot 12 of benchmark pipe end positioning component 2 and the consistency of thickness of benchmark blade 9, convenient for positioning, tail pipe detection components The wide thickness with benchmark blade 9 of the width of 4 slot 12, convenient for detection long bend pipe tail pipe end profile tolerance of a surface, and benchmark baffle 8 is more It changes conveniently.Single shaft guiding vertical plate 11 is mounted on bottom plate 1 using supporting element 13, and the height of supporting element 13 is adjusted according to actual needs It is whole.

Bottom plate 1 can use template of one block of thickness >=30mm steel plate as cubing, increase when with pipe range, this block is made For template steel plate length >=1 meter when, lower part of steel plate, which can be fixed four stiffening plates 14 by its appearance profile and be added, constitutes cubing moulds The structure of plate.

Application method: the inspection cylinder 6 at both ends is pulled open and (has used the structure of ball guide post at two), long bend pipe is placed on Intermediate standard is examined in the groove of block 3；Inspection cylinder 6 at benchmark pipe end positioning component 2 is positioned and is inserted into length by rotation driving handle 10 The reference edge of bend pipe is on earth；4 end of tail pipe detection components inspection cylinder 6 is inserted in tail pipe on earth later, rotates the driving hand at the end at this time Handle 10 observes whether benchmark blade 9 can be put into slot 12, and whether the surface profile to judge tail pipe end face is up to standard；It is curved referring finally to length Whether pipe pipeline is in standard inspection block 3；The position degree (standard examines 3 opening direction of block) of long bend pipe vertical direction, which can be used, appoints What plane examination board patch is neat to examine block upper surface to be detected.

Long bend pipe cubing is different from the cubing of short tube is examined, because of the long base for needing one piece of bottom plate as cubing of pipeline Quasi-mode plate, the utility model is mainly by cubing template (including big bottom plate and stiffening plate), benchmark pipe end positioning component, multiple standards Examine the composition such as block, tail pipe detection components and measuring basis block.Wherein benchmark pipe end positioning component and tail pipe detection components are rolling The structure of pearl guide post driving, tail pipe detection components also have the function of detecting tail pipe end face surface profile, several standards at middle part Inspection block can design different internal diameter and tolerance to examine the different location degree requirement of middle part pipeline section, and structure is simple, at low cost, behaviour It is convenient to make.
