The technical scheme adopted by the utility model is as follows:
a steel pipe welding butt joint tool comprises annular skeleton steel plates, an upper connecting rod, a lower connecting rod, a fixing plate, a limiting plate, a fixing bolt and a fixing bolt, wherein the annular skeleton steel plates are respectively sleeved on two butt joint steel pipes; the annular skeleton steel plate is provided with a rectangular groove for inserting the limiting plate, and the fixing plate is provided with a second round hole; the fixed plate and the limiting plates are fixed through fixing bolts inserted into the second round holes and the kidney holes, and the two limiting plates are fixed through fixing bolts inserted into the first round holes.
Further, the limiting plate is provided with a graduated scale.
Further, the steel pipe welding butt joint tool further comprises a fine tuning bolt, a bolt hole is formed in the annular skeleton steel plate, and the fine tuning bolt is inserted into the bolt hole to be fixed.
Further, the number of the fixing plates is 3, and the fixing plates and the bolt holes are uniformly distributed on the outer side face of the annular skeleton steel plate.
The utility model has the beneficial effects that:
the utility model has simple structure and high steel pipe butt joint precision, effectively controls the welding seam misalignment amount, and ensures the strength and the service life of the steel pipe so as to improve the welding quality; the butt joint time of the pipeline assembly is shortened, and the working efficiency is improved; the utility model is suitable for welding butt joint of different pipe diameters, is convenient to mount and dismount, can be recycled and used repeatedly, and reduces the construction cost.
