[0002] The surfacing device is a device that uses electric welding or gas welding to melt metal and deposit it on tools or parts.

[0003] In existing deep-sea oil machinery, as the working condition of oil layer becomes more and more severe, the exploitation of high-sulfur oil fields increases, and pipe fittings gradually use martensitic stainless steel with high strength and high toughness. The demand for nickel-based alloy material for corrosion-resistant surfacing on the joint part of such pipe fittings is also increasing.

[0004] Traditional surfacing devices mostly place pipe fittings on a workbench and move the welding gun nozzle in different directions to achieve surfacing repair on part of the surface. The pipe fittings are then flipped to meet the surfacing repair requirements on the other surface. However, for pipe fittings with joints, the shape and size of different types of joints are different, and the workbench cannot accommodate multiple types of joints. After each flip, the joint is not stable and cannot be locked in place, making the operation complex and inefficient. SUMMARY

[0006] Preferably, the locking assembly includes a locking sleeve and a compression bolt, a screw hole is formed in the side surface of the locking sleeve, and the compression bolt is inserted into the screw hole.

[0007] Preferably, the lifting column includes an outer cylinder, an inner column, and a locking pin, the lower end of the outer cylinder is fixedly connected with the workbench, a positioning outer hole is formed in the outer cylinder, the lower end of the inner column is slidingly arranged in the outer cylinder, the upper end of the inner column is fixedly connected with the horizontal plate, a plurality of vertically arranged positioning inner holes are formed in the inner column, the positioning inner holes correspond to the positioning outer holes, and the locking pin is inserted into the positioning outer hole and one of the positioning inner holes.

[0008] Preferably, the cross section of the inner column is square, and the outer cylinder is adapted to the inner column.

[0009] Preferably, the centers of the first vertical hole, the second vertical hole, the rotating gear and the locking sleeve are all on the same vertical line, and the first vertical hole and the second vertical hole are adapted to the pipe fitting.

[0010] The advantages and beneficial effects of this utility model are as follows: It provides a pipe fitting joint overlay welding device for sulfur-containing oilfield development. The pipe fitting is placed vertically on the worktable by the cooperation of the first and second vertical holes. The lifting plate lifts the pipe fitting, so that the joint of the pipe fitting is located above the worktable, which is convenient for adapting to various types of joints. Then, by rotating the gear plate, the pipe fitting can be rotated, which can adjust the position of the joint on the pipe fitting, which is convenient for multi-directional overlay welding repair of the joint on the pipe fitting. The operation is simple and the processing efficiency is improved. Attached Figure Description

[0015] The locking assembly 11 includes a locking sleeve 111 and a clamping bolt 112. The locking sleeve 111 has a screw hole 113 on its side, and the clamping bolt 112 passes through the screw hole 113. In actual use, the lower end of the pipe 2 is inserted into the locking sleeve 111, and the clamping bolt 112 is tightened so that the inner end of the clamping bolt 112 abuts against the pipe 2. Thus, the locking assembly 11 fixes the pipe 2 to the rotating gear 9.
