Description

Rotary welding device for pipe fitting of skid-mounted product

Technical Field

The utility model relates to a petroleum industry, concretely relates to rotatory welding set of pipe fitting of sled dress product among the petroleum industry.

Background

As is well known, an oil skid-mounted product is composed of various parts such as valves, pipelines, elbows and the like, and the parts are connected in a manner that the rest parts are welded except for flange connection. The welding position has high requirements, and the welding position must be subjected to radiographic inspection and 30MPa hydrostatic test.

The skid-mounted product of the oil industry, as shown in fig. 1, has four ports,

one of the outlets is connected with an oil extraction wellhead device. During the working process, high-pressure clear water is pumped in from the inlet to balance the gaps of the ground bottom after oil extraction of the three well heads at one time. Because the underground crude oil has pressure, the whole pipeline needs to bear the test pressure of 30MPa when being designed. The skid-mounted product is provided with a complex valve and pipeline connection, the pipeline connection adopts welding, a welding part needs to bear the pressure, before the test, the butt welding part needs to be subjected to radiographic inspection, and after the radiographic inspection, the assembly test can be carried out, so that the requirement on the welding seam is very high.

In the former welding, after the pipe and the pipe (or a welding flange) are positioned, a worker manually rotates the pipe to weld, the welding quality is unqualified in a large proportion, reworking is needed, time and labor are wasted, and the efficiency is low.

Disclosure of Invention

The utility model aims to provide a: the utility model provides a pipe fitting spin welding device of sled dress product, it is rotatory through foot switch control and speed governing motor, the three-jaw chuck through the motor front end drives the weldment and rotates, and longer weldment cooperation rotatable bracket supports, improves welding efficiency, guarantees the quality.

The technical solution of the utility model is that: the pipe fitting spin welding device for the skid-mounted product comprises a base, a motor, a speed regulator, a three-jaw chuck and a foot switch, wherein the motor, the speed regulator and the foot switch are respectively installed on the base, the speed regulator and the foot switch are connected with the motor, and the three-jaw chuck is installed on an output shaft of the motor.

Still further, the support bracket comprises a base, an adjusting screw rod and a bracket, wherein the adjusting screw rod is arranged on the base, and the bracket is arranged at the top end of the adjusting screw rod.

Furthermore, a V-shaped groove is arranged on the bracket, and a rolling bearing is arranged in the V-shaped groove.

The utility model has the advantages that:

1. the rotation of foot switch control motor, it makes the motor rotate to step on foot switch during the welding, loosens foot switch motor stall after the welding, opens and stops all to control by the people, accomplishes to have in the heart to count.

2. The diameter of the pipe on the whole set of equipment is large or small, so that the speed of an operator during welding can be changed; the normal motor is decelerated through the gear box, and the speed is constant; the welding speed is further adjusted by the speed regulator to adapt to different pipe diameters.

3. The length of the welding workpiece is short, and when the extending length is long, the welding workpiece is supported by a bracket with adjustable height.

4. The motor, the speed regulator and the foot switch control the rotating speed of the motor, the chuck clamps a workpiece, the bracket supports the workpiece, the welding is continuous and uniform, the welding quality is ensured, and the welding fixture is suitable for welding pipe fittings with different diameters.

5. The motor, the three-jaw chuck and the bracket are adopted for cooperation, so that the welding workpiece can synchronously rotate during welding, the movement is stable, the labor productivity is high, and the operation is safe and reliable.
