Abstract
The invention discloses a chain pipe manufacturing frame and a method for manufacturing a chain pipe. The chain pipe manufacturing frame comprises a supporting device which is supported in the chain pipe, and a bracket which is positioned at the bottom of the chain pipe, wherein the supporting device comprises at least two supporting rods of which ends are connected and lengths are equal. The chain pipe manufacturing frame supports the interior of the processed chain pipe, so that the chain pipe can be effectively prevented from being deformed during manufacturing, and quality of a product is prevented from being influenced. Moreover, a constructor assembles and welds the interior of the chain pipe, so high-attitude operation is changed into low-attitude operation, and the safety hazard of the constructor in the high-attitude operation is effectively eliminated. Further, the chain pipe can keep stable relative to ground in the machining process by the bracket which is positioned at the bottom of the chain pipe, and the chain pipe is driven by a guide wheel to rotate around a central shaft of the chain pipe, so the constructor can conveniently weld arc sheets to be processed sequentially.

Brief description of the drawings
Fig. 1 is the use view that the chain pipe in the present invention is made frame.
Detailed description of the invention
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1, chain pipe in the present invention is made frame and is comprised a bracing or strutting arrangement that is supported in chain pipe inside, in fact refer to the cross section sealing or the semi-enclosed circular space that are surrounded by the arc-shaped plate to be processed of assembling chain pipe in this alleged " chain pipe inside ", in order to make description more simple, referred to herein as chain pipe inside.This bracing or strutting arrangement comprises three isometric support bars 1, and the end 11 of described support bar 1 interfixes, and the angle between adjacent supports bar can not equate or not etc., but the summation of its angle is 360 °.Preferably, the angle between two adjacent support bars 1 is 120 °.That is to say, be connected to an intersection point taking the extended line of three support bars 1 as the center of circle in this bracing or strutting arrangement, taking the length of support bar 1, in the circle of radius, and this circle is justified for waiting with the circle at chain pipe cross section place.Two adjacent support bars 1 support to its outside for arc-shaped plate 4 inside to be processed, and two bracing or strutting arrangements 1 are supported in respectively two edges that upwarp of this arc-shaped plate 4 to be processed.Taking the support bar 1 of Fig. 1 lower left corner as example, this support bar 1 supports arc-shaped plate to be processed 4 along its bearing of trend (being radial direction), and the power of support force can be divided into along component F straight down
ywith level component F left
x, under the effect of two component, making arc-shaped plate to be processed remain on a central angle is the state of 120 °, prevents that it from deformation occurring in welding process.Adjacent two support bars 1 and an arc-shaped plate 4 to be processed form the sector space of a sealing.
In addition, between two adjacent support bars 1, be provided with a ribs 3, prevent that deformation occurs support bar 1 in support process, affect support effect.
Or, the end of the support bar of this bracing or strutting arrangement adopts and is flexibly connected, thereby can, according to the arc-shaped plate to be processed of different size (being different radians or different arc), the angle between adjacent two support bars be adjusted, thereby expanded the scope of application.For example, the end of each support bar is connected with two nut (not shown) that are arranged on screw rod end by a screw rod (not shown).
More preferably, be provided with two telescoping mechanisms 2 at the free end 12 of every support bar 1, this telescoping mechanism 2 can move along the bearing of trend of the support bar at its place 1, reach the object of adjusting the effective length of support bar 1 according to the chain pipe of different-diameter, it is supported at two ends of the arc-shaped plate to be processed to composition chain pipe effectively.The effective length of described support bar refers to, the intersection point of three support bar extended lines is to the distance of telescoping mechanism outermost end.
In the present embodiment, each telescoping mechanism 2 includes one and is located at the substrate 21 of this support bar side and is plugged in the slide plate 22 paralleling with this substrate 21 in this substrate 21, on this this slide plate, 22 are provided with the chute (not shown) that a bearing of trend is identical with the bearing of trend of this support bar 1, substrate 21 is connected with the free end 12 of support bar 1 by two screws 23 with slide plate 22, and the chute on this slide plate 22 slides at the bearing of trend of support bar 1 under coordinating with screw 23 simultaneously.More preferably, in order to prevent that arc-shaped plate to be processed from contacting with the end of slide plate 22, skidding occurs, can set up one deck skid resistant course (not shown) in the end of slide plate 22, this skid resistant course can adopt rubber, and the materials such as sponge are made.
As shown in Figure 1, an arc-shaped plate to be processed supports by two telescoping mechanisms between two support bars 1.That is to say, two telescoping mechanisms on same support bar are across the both sides of boundary that lay respectively at two arc-shaped plates to be processed.
In order better to make columned chain pipe relative ground in assembling process keep balance and stable state, constructability personnel carry out welding assembly operation in chain pipe inside, and change position to be welded, the chain pipe in the present invention is made frame and is also comprised a bracket 7 of being located at chain pipe bottom.This bracket 7 comprises the pedestal 71 of a level, respectively be provided with a guide wheel 72 at the two ends of pedestal 71, the rotating shaft of described guide wheel 72 is all parallel with the axis of this chain pipe, and the size of two guide wheels 72 can not equate or not etc., and this guide wheel 72 can be driven or be passed through driven by power by manpower.When workmen completes respectively arc sheet material 4 and arc-shaped plate 5 to be processed, and after weld job between arc-shaped plate 4 to be processed and arc-shaped plate 6 to be processed, can drive chain pipe by the rotation of guide wheel 72 (is arc-shaped plate 4 to be processed, the enclosed construction of 5 and 6 compositions) rotate around the axis of this chain pipe, by arc-shaped plate to be processed 5 and arc-shaped plate 6 to be processed border on part from the rotary-top of chain pipe to side or bottom, constructability personnel carry out weld job to it.Thereby be converted to low idle job by originally needing workmen to step on to the work high above the ground at chain pipe top, effectively stopped potential safety hazard, guaranteed construction safety, also reduced that arc-shaped plate to be processed bears workmen's gravity and possibility that deformation occurs.
It should be noted that, this chain pipe is made angle between quantity and the adjacent supports bar of support bar of frame and can be determined according to the size of the size of the chain pipe in actual production and arc-shaped plate to be processed.Determining of described angle will elaborate in the method for making chain pipe below.
