Abstract
Disclosed is a universal drawing instrument for pipe elbow, which is a tool for making steel pipe elbow during the maintenance and installment of pipes. The drawing instrument is composed of a jacket seat tightly arranged on the steel pipe by a push rod, a cradle rotating around a fixed rotation shaft, a graduated disk indicating the angle, two guide rails arranged on the cradle and a paint brush which is perpendicular to the guide rails and is driven by the slide blocks sliding on the guide rails. When the jacket seat is pushed tightly and the cradle make the rotation angle of the guide rails determined, the slide blocks are moved to make the paint brush move on the steel pipe, thus realizing the drawing of the pipe elbow, thoroughly abandoning the present magnifying sample process.
Description
When being the pipeline I﹠M, makes the omnipotent line-drawing instrument of the curved joint of pipeline the instrument of steel elbow.
The setting-out of curved joint is the full-page proof that draws earlier on ready full-page proof material earlier in the conventional steel elbow, it is the expanded view of curved joint, again along (the flexible plate of material) under the edge scissor of expanded view, Here it is amplifies sample, after with the full-page proof rewinding on steel pipe, so just finish the curved setting-out that saves along the edge setting-out, a full-page proof can only be produced a kind of curved joint.
The purpose of this utility model is without said process, promptly without amplifying sample, can be installed on the steel pipe, according to different needs.The curved joint that directly draws on different steel pipes can be on the pipe of various outer diameter, in case determine good angle, the paintbrush head is by determining that two good guide levels do the motion of both direction, and the one, along the guide rail direction, the 2nd, along the guide rail vertical direction, finish the setting-out of curved joint.
On the steel pipe that can be installed in various outer diameter, block set of the present utility model is held out against on steel pipe by threaded mandrel, to be suitable for outer warp as much as possible economically.Adopt dial and reel cage to determine the angle of curved joint, and guide rail is installed on the parallel plane of shaft axis, and when angle be 0 with the steel pipe axis normal, slide block on being contained in guide rail drives paintbrush on guide rail when mobile, the vestige that the paintbrush head stays on steel pipe is exactly the curved nodel line that we need.The vestige of paintbrush head is after closure on the steel pipe, and one section curved nodel line has just been finished, and its whole track is the three-dimensional motion of the origin of coordinates on steel tube section, has realized three-dimensional setting-out.
Edition with parallel text utility model and conventional art, be not difficult to find out following advantage and good effect:
1. difficulty is low, is easy to grasp, and need not learn geometrograph, removes angle and still need calculate, and other does not all need to calculate.
2. disposable setting-out improves tens times of work efficiency, has shortened making man-hour.
3. saved amplification sample material.
4. simplified technology, improved precision, former technology is by the error of setting-out mapping own, and operate miss is repeatedly brought when cutting full-page proof.
Shown in the accompanying drawing: Fig. 1 is main pseudosection, and Fig. 2 is a vertical view.There are thread bush (4) and rotating shaft (12) to determine the pivot center of reel cage (10) on the block set (1), round pin (3) is to make push rod (6) block set (1) when holding out against steel pipe be difficult for skew with the design of top (2), presses spiral shell (5) to be used for compressing reel cage (10).Handle (7) rotates push rod when holding out against steel pipe.Reel cage (10) is plane and a steel pipe axis angle of determining the guide rail decision, and by dial (13) indication, guide rail (8) guarantees that with slide block (11) paintbrush (9) moves in the plane of needs, and with the steel pipe axis normal.
Claims (6)
1, the omnipotent line-drawing instrument of the curved joint of a kind of pipeline by dial (13), can be installed in the block set (1) on the steel pipe, reel cage (10), and push rod (6) presses spiral shell (5) to form, and it is characterized in that:
A., thread bush (4) and rotating shaft (12) are arranged on the block set of described line-drawing instrument (1),
B. on the reel cage of described line-drawing instrument (10) two guide rails (8) are arranged,
C. on this guide rail (8) slide block (11) is arranged,
D. on this slide block (11) paintbrush (9) is arranged.
2, line-drawing instrument according to claim 1 is characterized in that reel cage (10) rotation axis that can rotate rotates.
3, it is characterized in that according to claim 1,2 described line-drawing instruments the pivot center of reel cage (10) is definite by rotating shaft (12) and thread bush (4).
4, line-drawing instrument according to claim 1 is characterized in that guide rail (8) is installed in the plane with shaft parallel.
5, it is characterized in that the plane that guide rail (8) is installed according to claim 1,4 described line-drawing instruments, when reel cage (10) corner is 0, with the steel pipe axis normal.
6, line-drawing instrument according to claim 1 is characterized in that slide block (11) makes paintbrush (9) perpendicular to guide rail (8).
