Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment for parts of mining machinery. Background Art

[0002] When mining, a large number of mining equipment are needed to explore and excavate the mine. During the mine exploration process, steel pipes need to be driven into the surface to extract internal water and gas. During the steel pipe exploration and transportation process, when the steel pipe is damaged or the length is insufficient, the steel pipe needs to be welded to facilitate the reuse of the steel pipe. When welding steel pipes traditionally, the following problems exist: First, the steel pipes are welded by manually holding a welding gun. This operation method requires skilled welding workers. For the smooth cylindrical surface of the steel pipe, it is difficult for ordinary welders to rotate and weld it at the same time. Either increase human resources and send more people to manually clamp and rotate it. In this way, the operation is time-consuming and labor-intensive, which is very inconvenient.

[0003] In the prior art, pipe fittings are clamped and positioned by welding equipment in the form of a frame to ensure alignment before welding, which can ensure welding alignment and improve welding efficiency. However, this technical method cannot meet the welding needs of multiple pipe sections. When actually processing pipes, multiple pipe sections may need to be welded due to the required length. However, the length of outdoor welding equipment is limited and it may not be possible to place all pipes on the welding equipment. Therefore, some pipes will be exposed outside. In the absence of support, it is easy for the other pipe openings to be misaligned due to their own weight, affecting the welding effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a welding device for parts of mining machinery to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure.

Through the cooperation of a moving component and a clamping component, the two welded pipe sections are pushed out of the welding position through the clamping action of the bottom and both sides, and a new pipe is added from the inlet end of the processing box to continue the welding work with one end of the original welded pipe.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention uses a cylinder to drive the welding device and the auxiliary wheels to move up and down. The brackets on both sides of the auxiliary wheels slide along the sides of the processing box to guide the movement of the auxiliary wheels. The positions of the welding device and the auxiliary wheels can be adjusted in coordination with the movement of the driving wheel so that they can maintain contact with the top of the pipe fitting and prevent the pipe fitting from jumping when the pipe fitting rotates with the driving wheel.

[0017] 2. The present invention drives the driving shaft to rotate through the second motor. Because the active bevel gear is clamped with the convex strip, it will rotate with the driving shaft. The active bevel gear is meshed with the driven bevel gear, driving the driving wheels on both sides to rotate synchronously, and driving the pipe fittings to rotate slowly during the processing. Because the driving wheels at the bottom of the two groups of pipe fittings are connected by an axle rod, the rotation speed is the same, and the stability of welding can be maintained. When facing pipe fittings of different calibers, the third motor is turned on to drive the bidirectional screw to rotate, and the sliding seat of the axle rod cooperates with the bidirectional screw thread to slide along the sliding frame, and the mounting frame drives the active bevel gear to slide along the surface of the driving shaft. Because the driving shaft is provided with convex strips on the upper and lower parts, the active bevel gear can move while maintaining the clamping relationship with the driving shaft.

[0018] 3. After the welding of two sections of pipe fittings is completed, the electric push rod drives the bottom extrusion plate to contact the bottoms of the two pipe fittings. As the bottom extrusion plate passes through the moving notch, it drives the two connecting rods to rotate, pulling the connecting plate and the side extrusion plate to move toward the side of the pipe fitting. The telescopic rod extends until the side of the pipe fitting is squeezed and fixed, keeping the pipe fittings clamped and fixed on both sides and the bottom, making it convenient to send the pipe part out of the processing box through the moving assembly. The connecting rod can be a telescopic type, and the length can be adjusted when used for welding pipe fittings of different calibers, so that the bottom extrusion plate and the side extrusion plate can squeeze the side and bottom of the pipe fitting at the same time.

[0019] 4. The present invention starts the first motor to drive the one-way screw to rotate, and the movable plate cooperates with the one-way screw thread to move outward along the movable frame. At this time, the outer pull plate moves out of the bottom box, and cooperates with the clamping assembly to pull the welded pipe part out of the processing box, so as to facilitate the subsequent welding of the pipeline.

[0020] 5. Compared with the prior art, the present invention adjusts the rear limit of pipes of different sizes through the cooperation of the driving assembly, the driving wheel and the auxiliary wheel, and drives the pipes for rotational welding. Through the cooperation of the moving assembly and the clamping assembly, the two welded pipe sections are pushed out of the welding position through the clamping action of the bottom and both sides, and a new pipe is added from the inlet end of the processing box to continue the welding work with one end of the original welded pipe. In this process, the moved pipe is clamped and supported to maintain the same axis with the newly introduced pipe, so as not to interfere with the welding result, thereby improving the welding efficiency.

Then, two sections of pipes are placed in the processing box 1, and the pipe fittings 4 are placed on the driving wheels 5 on both sides. The second motor 81 drives the driving shaft 82 to rotate. Because the active bevel gear 85 is engaged with the convex strip 83, it will rotate with the driving shaft 82. The active bevel gear 85 is meshed with the driven bevel gear 86, driving the driving wheels 5 on both sides to rotate synchronously.
