Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, the fixed device of the small pipeline centering of heretofore described adjustable-angle, including
First cantilever 1 and the second cantilever 2, first cantilever 1 and the second cantilever 2 are respectively provided with connecting pin and cantilever end, and first
The articulated connection of subtended angle is adjusted by respective connecting pin for cantilever 1 and the second cantilever 2, in the first cantilever 1 and the second cantilever 2
Pipe fixing holder 3 is respectively arranged on cantilever end.Wherein, heretofore described small pipeline refers to diameter less than DN80's
Pipeline；Since large-scale pipeline diameter is big, weight is big, it has not been convenient to carry out angular adjustment through the invention；Therefore the main needle of the present invention
The operation such as the centering of small pipeline is fixed and is connected.
The present invention is fixed for the centering of pipeline, and its purpose is to the docking of pipeline to provide operating condition.Referring to attached drawing
Shown in, pipe fixing holder 3 is the mechanism for clamping and fixing the pipeline 4 that needs dock, by respectively in 1 He of the first cantilever
The pipe fixing holder 3 being arranged on the cantilever end of second cantilever 2 is to clamp respectively and fix two pipelines 4 to be docked.Certainly, no
Generality is lost, due to needing centering to fix two root canal roads 4, the position of two pipe fixing holders 3 should be at same level
On face, to ensure that two root canal roads 4 after clamping are on identical horizontal position, it is ensured that the accuracy of centering.
Secondly as the first cantilever 1 and the second cantilever 2 in the present invention are articulated connection, therefore the two can occur relatively
Rotation, in this way by relatively rotating the first cantilever 1 and the second cantilever 2 to drive the pipeline being fixed on corresponding pipeline fixing clamp 34
It deflects therewith, and then realizes the adjusting of the drift angle between two root canal roads 4；In this way, two root canal roads 4 can be realized to middle company
It can be spliced according to specific deflection angle in termination process.Without loss of generality, the first cantilever 1 and the second cantilever in the present invention
2 are preferably set as rectangular steel plate, and the thickness of steel plate is preferably 5mm, and the two may be configured as identical shape
Shape and size.More specifically, as indicated by attached drawing, the connecting pin of the first cantilever 1 in the present invention and the connection of the second cantilever 2
End by can elastic adjusting bolt 5 be articulated and connected；In this way, can when needing to adjust the drift angle of the first cantilever 1 and the second cantilever 2
Bolt 5 is unclamped, and then can fastening bolt 5 when needing fixed.More specifically, the bolt 5 includes screw rod and is sleeved on the screw rod
Wing nut；It is more convenient for that the elastic of bolt 5 is adjusted in this way.
More specifically, the pipe fixing holder 3 is further arranged in the present invention includes the L shape angle steel 31 with certain length
With fastening screw 32；It is the rest area of pipeline 4 on the inside of L shape angle steel 31, and pipeline 4 is placed on rest area its rear axis side
To consistent with the length direction of L shape angle steel 31；The fastening screw 32 is mounted on L shape angle by mounting plate 33 telescopically adjustablely
On steel 31, and the telescopic adjustment direction of fastening screw 32 is vertical with the length direction of L shape angle steel 31；The outer end of fastening screw 32
For knob end 321, the inner end of fastening screw 32 is to push against end 322, and push against end 322 and be deep into putting for 31 inside of L shape angle steel
It sets in area.
The pipe fixing bracket 3 of above-mentioned specific structure has the advantages that structure is simple, and it is non-to the clipping operation of pipeline 4
It is often convenient: pipeline 4 to be placed by the rest area that L shape angle steel 31 is formed, and by the way that pipeline 4 is pushed against turning for L shape angle steel 31
It can ensure that pipeline 4 is placed along the length direction of L shape angle steel 31 at angle；And there is certain length by setting L shape angle steel 31, such as
It is set as the length of 10cm, can ensure that the linear fixed effect to pipeline 4 in this way.In addition, fastening screw 32 is then for pipe
Road 4 applies clamping force, to ensure that pipeline 4 can be pushed against in the inside rest area of L shape angle steel 31.More specifically, it fastens
Screw 32 can be set as the shape of wing nut at its knob end 321, as it is shown in the figures, being more convenient for screwing in this way.
In addition, in order to accurately acquire the deflection angle between the first cantilever 1 and the second cantilever 2, referring to shown in attached drawing,
The present invention is further provided with angle index line 6 close to connecting pin on the first cantilever 1；The angle index line 6 is for measuring
The angle value that first cantilever 1 and the second cantilever 2 relatively rotate.Corresponding angle can be set according to actual conditions in angle index line 6
Value, and need that the determination deflection angle cooperated referring to graduation mark and angle index line 6 accordingly is arranged on the second cantilever 2.
For example, the edge referring to graduation mark for the second cantilever 2 can directly be arranged；It is carved in this way when the edge of the second cantilever 2 turns to angle
When spending corresponding scale value on line 6, that is, it is convenient to obtain the deflection angle between the first cantilever 1 and the second cantilever 2, and then obtain
Take the deflection angle between two root canal roads 4.More specifically, for the scale value being arranged under reference data state, scale value is set
Following requirement can be met by setting: when the middle line for the pipeline 4 being respectively clamped on the first cantilever 1 and the second cantilever 2 is overlapped, such as attached drawing
Under state shown in 2, setting is 180 ° referring to the scale value of the corresponding angle index line 6 of graduation mark；180 ° can be made in this way
For the angle under benchmark state.In addition, without loss of generality, angle index line 6 may also be arranged on the second cantilever 2, exist accordingly
First cantilever 1 is arranged corresponding referring to graduation mark.
Use device of the present invention for concrete operation method steps are as follows:
(1) it is put into pipeline 4 in 31, a L shape angle steel thereto, and tightens corresponding fastening screw 32 tentatively will correspond to
Pipeline 4 clamp.
(2) the first cantilever 1 and the second cantilever 2 are then relatively rotated, according to corresponding reference graduation mark in angle index line 6
Upper corresponding angle value, determines the angle for needing to deflect；Then the subtended angle that bolt 5 makes the first cantilever 1 and the second cantilever 2 is tightened
It is fixed up.
(3) it is put into pipeline 4 in backward another 31, L shape angle steel, and tightens corresponding fastening screw 32 tentatively with will be right
The pipeline 4 answered clamps.
(4) it after two pipelines 4 being put into, is finely adjusted and puts according to the gap of level weld seam requirement, tightened after adjustment
Corresponding fastening screw 32, to be completely fixed two root canal roads 4.Stitching operation can be carried out later；Such as pipeline 4 be steel pipe when
Welding can be used to be spliced, and when drift angle is larger, can also be provided with elbow between two root canal roads 4 and be attached.
