Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at circle position in Fig. 1.
Wherein, 1 is perpendicular chi, and 2 is crossfoot, and 3 is connecting tee, and 4 is perpendicular chi pedestal, and 5 is steel pipe, and 6 is micrometer head, and 6-1 is fixed muffle, and 6-2 is differential sleeve, and 6-3 is gauge head.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1, the utility model comprises the perpendicular chi of a crossfoot 2, two 1, two perpendicular chi pedestals 4 and a connecting tee 3, wherein, crossfoot 2 is dip stick, its xsect is circular, similar extension bar type micrometer inside caliper, and crossfoot 2 is made up of the different extension bar of some length and micrometer head 6.Each extension bar one end is with external thread, and the other end is with internal thread, and during use, extension bar is by the screw thread compact siro spinning technology of end.Extension bar quantity is 6 joints, and length respectively (removing external thread length) is 500mm, 500mm, 200mm, 100mm, 50mm, 25mm.
Micrometer head 6 is similar to the measuring head of conventional micrometer caliper (milscale), forms primarily of fixed muffle 6-1, locking device, differential sleeve 6-2.Fixed muffle 6-1, differential sleeve 6-2 are connected by locking device, and fixed muffle one end, also with external thread, can be connected with the extension bar of crossfoot.The differential sleeve other end, with gauge head 6-3, rotates differential sleeve 6-2 to gauge head 6-3 and encounters the perpendicular chi in right side during use.Micrometer head 6 is set to 100mm as standard length, and its range is 25mm.Scale on micrometer head, reading are identical with normal spiral mircrometer gauge.
Can obtain thus, the range ability of this dip stick is 100-1500mm (the corresponding maximum height of perpendicular chi is also 1500mm), and range ability covers the maximum caliber of existing pipeline.
Perpendicular chi 1 is elevation ruler, and its xsect is circular, and diameter is identical with crossfoot 2 diameter, and the extension bar identical by 3 joint length is formed, and often saves extension bar length (removing external thread length) and is set to 500mm.Extension bar lower end with external thread, upper end with internal thread, being threaded by end between extension bar during use.Often save on extension bar, be provided with a tapped through hole every 100mm, during use, be used for fixing connecting tee.
Perpendicular chi pedestal 4 is with the rectangular parallelepiped bloom of central through hole and an externally threaded round bar of band to form by one piece.Be provided with internal thread in through hole, internal thread mates mutually with round bar external thread, and round bar external thread length is identical with bloom thickness.First round bar and bloom are threaded connection during use, make bloom become plumbness with round bar.Round bar internal diameter is micro-is greater than perpendicular chi external diameter, is saved by perpendicular chi foot one and insert round bar inside during use, ensures that perpendicular chi keeps vertical with bloom.
Connecting tee 3 is responsible for that interior diameter is micro-is greater than perpendicular chi overall diameter, and supervisor center is provided with a through hole, inside has screw thread, is connected with perpendicular chi by bolt, nut, thus is fixedly connected with threeway position in height.Connecting tee 3 arm overall diameter is identical with crossfoot overall diameter, and arm inside is provided with internal thread, and internal thread mates with crossfoot extension bar external thread, can adopt be threaded with crossfoot extension bar.Prop up length of tube identical with the external thread length of crossfoot extension bar left end, when ensureing to be connected with crossfoot, crossfoot left end is just positioned at supervisor's outward flange (i.e. perpendicular chi outward flange).
The detailed process measured is: during measurement, point following steps:
Step one: assemble 2 perpendicular chi pedestals.Round bar is screwed into pedestal bloom.
Step 2: assemble 2 perpendicular chis.When measuring object external diameter is less than 500mm, 1 perpendicular chi only needs a joint to erect chi extension bar; When external diameter is in 500-1000mm, need the perpendicular chi extension bar of two joints; When external diameter is more than 1000mm, need the perpendicular chi extension bar of three joints.Perpendicular chi extension bar end thread is tightened successively and can be completed assembling.
Step 3: erect in side on chi and install connecting tee.The setting height(from bottom) of connecting tee on perpendicular chi is highly advisable to exceed steel pipe 5 overall diameter 0-100mm.After determining setting height(from bottom), perpendicular chi is selected and this highly immediate threaded hole, connecting tee is arranged on this threaded hole by bolt, nut.
Step 4: fixing perpendicular chi position.2 perpendicular chis (wherein 1 with connecting tee) are inserted respective perpendicular chi pedestal respectively.Be placed in same level position by bottom perpendicular chi pedestal and steel pipe 5, and make the adjacent steel pipe left and right edges of perpendicular chi.
Step 5: assembling crossfoot.Select crossfoot extension bar quantity and length according to outer diameter of steel pipes, and connected successively by extension bar, load onto micrometer head at crossfoot right-hand member, what carried by it by the left end of crossfoot is threaded in the arm of connecting tee.
Step 6: measure and reading.Hold crossfoot right-hand member, rotate micrometer head, make it encounter threaded hole on the montant sustained height of right side, read the length data on now crossfoot, be the overall diameter of steel pipe under current location.
