Technical field

This application relates to the technical field of spiral welded pipe welding, and specifically discloses a positioning and anti-offset mechanism during welding of spiral welded pipes.

Background technique

Spiral welded pipe is a steel pipe made by rolling low carbon structural steel or low alloy structural steel strip into a pipe blank at a certain spiral angle, and then welding the pipe seams. The steel pipe welded by this process usually has a high Strength of.

At present, to prevent the spiral welded pipe from deflecting during welding, fixed rollers are used to lift the formed steel pipe. The rollers guide the formed steel pipe to keep the steel pipe moving stably. However, this method avoids the problem of spiral welded pipe. The offset effect is not good. For example, the positioning and anti-offset mechanism during spiral welded pipe welding described in the publication number CN215393559U includes an upper fixed plate, a lower fixed plate, a support frame and a support wheel slidably connected to the lower fixed plate. And a clamping plate fixed on the upper fixed plate for clamping the spiral welded pipe. This utility model realizes the positioning and anti-deviation of the spiral welded pipe through the support wheel and the clamping plate. However, due to the fixed height of the clamping plate, when encountering For spiral welded pipes with smaller diameters, the clamping plate cannot offset the pipe wall of the spiral welded pipe, making it impossible to position the upper side of the spiral welded pipe. The support wheel can only position the lower side of the spiral welded pipe, and the support wheel alone can It is difficult to achieve positioning and anti-offset, and the positioning effect is poor. Therefore, a mechanism that can position and prevent offset according to different pipe diameters is needed.

Therefore, in view of this, the inventor provides a positioning and deviation-preventing mechanism during welding of spiral welded pipes in order to solve the above problems.

Rotate the positioning roller connected to the connecting rod and the functional part provided on the rotating rod to position the spiral welded pipe. At the same time, since both the supporting rod and the rotating rod can rotate, the rotation angle of the supporting rod and the rotating rod can be adjusted to achieve different positions. The positioning effect of spiral welded pipes with different diameters solves the problem that the existing positioning and anti-offset mechanism during welding of spiral welded pipes cannot position spiral welded pipes of different diameters, resulting in poor anti-offset effects.

2. This utility model facilitates the transportation of spiral welded pipes through the set of transmission components. At the same time, it cooperates with the rotatable positioning roller to position the spiral welded pipes without interfering with the transportation of spiral welded pipes. It is different from the traditional hoisting and transportation that requires a hoisting machine. Compared with the above, the efficiency is improved. At the same time, the utility model uses the oblique upward thrust of the electric push rod to decompose the thrust into the force of pushing the support tube to rotate and pushing the sliding sleeve to slide. The support tube is supported by the positioning roller on the connecting rod when rotating. The spiral welded pipe on the table has the effect of squeezing and positioning.

The cleaning component includes a dust suction box with an air suction pump inside, a number of suction heads arranged on the support plate, and suction heads. The other end of the connected suction pipe extends into the vacuum box and is connected to the suction pump. Through the cooperation of the dust collection box, suction head and suction pipe, the welding chips on the belt are absorbed to prevent the welding chips from affecting the welding quality of the spiral welded pipe.

Furthermore, the belt is provided with anti-slip patterns for increasing the friction of the spiral welded pipe. The anti-skid texture increases the friction with the spiral welded pipe, thereby enhancing the anti-deviation effect of the spiral welded pipe.

Further, the functional component includes a limiting rod fixed on the other end of the rotating rod, a rotating hole provided on the limiting rod, a rotating shaft connected to the rotating hole and capable of rotating, and a positioning roller fixed on the rotating shaft. Limiting by positioning rollers.

Further, the length of the rotating rod is greater than the length of the connecting rod. This enables the rotating rod to have better positioning effect.
