Description
Technical field
The present invention relates to welding auxiliary implement, be specially a kind of pipeline welding line-up clamp.
Background technology
Site operation, when welding pipeline, often due to cannot effective fixed-piping, thus affects the welding quality that pipeline connects, and secures pipeline and cannot meet mismatch gap uniformity, thus welding quality also cannot ensure.
For this reason, grant number is " steel pipe butt-jointing device " of (CN203649785U), proposes a kind of welding manner and is: the steel pipe of butt welding is placed on a pair on the roller rolled, and along with the rotation of roller, in fixed position, butt welded seam welds.
The shortcoming of this art solutions is the circularity inhomogeneities due to steel pipe, cannot ensure the even of weld gap in turning course.
Again this, grant number is " the large-scale steel pipe butt joint auxiliary device " of (CN203887464U), proposes another kind of welding manner and is: the steel pipe plate ear of butt welding is fixedly connected with, and welds around steel pipe butt welded seam.
The shortcoming of this art solutions is that being connected and installed of steel pipe is time-consuming, and inefficiency, the connection for stock size steel pipe is inapplicable.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention proposes a kind of highly versatile, easy to use, the light easy pipeline welding line-up clamp taken.
The pipeline welding line-up clamp that can solve the problems of the technologies described above, its technical scheme comprises location of pipeline mechanism and pipeline clamp system, described location of pipeline mechanism comprises the horizontal stationary pipes of placing for left and right pipeline, the opened upper end of described stationary pipes, the middle lower portion of stationary pipes offers the otch for weld seam welding; Described pipeline clamp system is included in the pressure pipe part of left and right setting above stationary pipes, left and right pressure pipe part comprises the left and right pressing plate corresponding to left and right duct arrangement, left and right pressing plate is located in left and right adjusting bolt respectively, left and right adjusting bolt is arranged on left and right bracing frame straight down respectively, when tightening left and right adjusting bolt, left and right briquetting compresses left and right pipeline in stationary pipes.
A kind of mode that support frame as described above adopts is folding shape plate body structure, and described adjusting bolt is installed and used its position of nut check on the transverse slat rolling over shape plate body, and the corresponding tube wall that riser and the stationary pipes of described folding shape plate body open wide place connects.
Beneficial effect of the present invention:
1, inventive pipeline welding line-up clamp adopts stationary pipes location and pressing plate to compress, and effectively improves harmony and the alignment clearance reasonable layout in pipeline welding mismatch gap, can significantly improve welding quality.
2, after having welded with the present invention, pipeline is kept, not producing distortion point-blank.
3, structure of the present invention is simple, easy to use, gently easyly takes, economical and practical, safe and reliable, conveniently promotes.

Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further.
Inventive pipeline welding line-up clamp, its technical scheme comprises location of pipeline mechanism and pipeline clamp system.
The main body of described location of pipeline mechanism is the horizontal stationary pipes 2 (steel pipe) of placing for left and right pipeline 1, the internal diameter of described stationary pipes 2 is greater than pipeline 1 external diameter of 1.5 times and is less than pipeline 1 external diameter of 2 times, the first half of stationary pipes 2 is cut and formed uncovered, the bottom of stationary pipes 2 middle part sets out otch 3, the height of described otch 3 higher than the center of pipeline 1, as shown in Figure 1 and Figure 2.
Described pipeline clamp system is included in the pressure pipe part of left and right setting above stationary pipes 2, described pressure pipe part comprises the pressing plate 4 (steel part) of left and right half arc, left and right pressing plate 4 respectively spiral shell seat is installed on the termination of left and right adjusting bolt 5, left and right adjusting bolt 5 is arranged on left and right bracing frame 6 straight down respectively, the center line of left and right adjusting bolt 5 aims at the center of circle of stationary pipes 2, as shown in Figure 1 and Figure 2.
Support frame as described above 6 adopts the folding shape plate body (steel plate bending is shaping) of inverted L-shaped, the riser of described folding shape plate body opens wide with stationary pipes 2 the corresponding tube wall located downwards and welds, described adjusting bolt 5 is combined on the screwed hole that the transverse slat of folding shape plate body is offered and also uses nut 7 locked position, described pressing plate 4 is arranged in adjusting bolt 5 by the spiral shell seat 8 of welding on it, the circularity of the radian coupling pipeline 1 that pressing plate 4 is downward, as shown in Figure 1 and Figure 2.
Using method of the present invention:
1, according to the diameter of (being required to weld) pipeline 1 (left and right same pipeline 1), select suitable pressing plate 4, pressing plate 4 is arranged on the termination of adjusting bolt 5, unscrews adjusting bolt 5 and upwards promote pressing plate 4 position, abdicate the placement space of left and right pipeline 1.
2, left and right pipeline 1 docking is placed in stationary pipes 2, the counterpart position of left and right pipeline 1 is made to be in otch 3 central authorities of stationary pipes 2, regulate the alignment clearance (welded gaps) of left and right pipeline 1, tighten adjusting bolt 5 times decompression board 4 positions, make left and right pressing plate 4 compress left and right pipeline 1 respectively in stationary pipes 2.
3, the alignment clearance of the left and right pipeline 1 of manual welding.
The welding of weld seam upper semicircumference is carried out from the open-mouth on stationary pipes 2 top, and the welding of second circumference of weld seam is carried out from the otch 3 of stationary pipes 2 bottom.
4, after weld seam cooling and shaping, unscrew adjusting bolt 5, upwards promote pressing plate 4, take out the left and right pipeline 1 welded.
