Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a pipe end welding device for seamless pipe fittings. Background Technology

[0002] The emergence of seamless pipe fittings is closely linked to the development of industrial pipeline systems. Early industrial pipeline connections mostly used welded pipe fittings. However, with the increasing demands for high pressure, high temperature, and high corrosion, problems such as easy leakage and insufficient strength of welded pipe fittings became prominent. To solve these defects, people began to explore the manufacturing of pipe fittings through integral forming processes. Seamless steel pipes were directly processed into elbows, tees, reducers, and other pipe fittings through hot pressing, cold drawing, extrusion, and other processes, avoiding the weak links caused by welds. This process can be traced back to the progress of steel smelting technology in the late 19th century. With the maturity of seamless steel pipe production technology, seamless pipe fittings, due to their excellent sealing performance, pressure resistance, and durability, have gradually become the mainstream in key fields such as petroleum, chemical, and power, becoming an important basic component for ensuring the safety of fluid transportation in modern industrial pipeline systems.

[0003] In existing technologies, seamless pipe fittings need to be welded to pipelines in oilfield gathering and transportation pipelines and long-distance natural gas pipelines to form a high-pressure transmission network. Pipe end welding equipment is mainly used to weld seamless pipe fittings to pipelines. During use, pipelines are prone to displacement and shaking during welding, which reduces the stability of the welding process. In addition, some fumes are generated during the welding process, which can have some impact on the health of operators.

[0004] Therefore, a pipe end welding device for seamless pipe fittings is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe end welding device for seamless pipe fittings, which solves the technical problems of easy displacement and shaking of pipes during welding, reducing the stability of welding, and the generation of fumes during the welding process, which may have some impact on the health of operators. The device achieves the purpose of clamping and fixing and fumes purification.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pipe end welding device for seamless pipe fittings, comprising a base plate, pads fixedly connected at equal intervals on both sides of the bottom of the base plate, a pipe one provided on one side of the top of the base plate, a pipe two provided on the other side of the top of the base plate, a clamping and fixing assembly provided on the top of the base plate, and a dust purification assembly provided on the top of the base plate.

[0007] Preferably, the clamping and fixing assembly specifically includes: a bracket, which is fixedly installed at equal intervals on both sides of the top of the base plate; a recess, which is fixedly installed circumferentially and evenly on the inner wall surface of the bracket; rollers, which are movably connected between the inner walls of the recess; and side plates, which are fixedly installed at equal intervals on both sides of the top of the base plate.

[0008] Preferably, the outer wall of the roller contacts the outer wall of pipe one and the outer wall of pipe two respectively, a sleeve plate is fixedly installed between the inner sides of the side plates, and a hydraulic rod is fixedly installed at equal intervals on one side of the sleeve plate.

[0009] Preferably, the telescopic end of the hydraulic rod is fixedly equipped with an arc-shaped clamping plate, and the inner side of the arc-shaped clamping plate is fixedly equipped with a rubber pad. The surface of the rubber pad is in contact with the outer wall of pipe one and the outer wall of pipe two, respectively. Through the evenly distributed concave blocks on the inner wall of the bracket and the movably connected rollers, it can tightly fit the outer walls of pipe one and pipe two. Utilizing the rolling characteristics of the rollers, it can not only support the weight of the pipes, but also assist in adjusting the angle when the pipes are joined, ensuring the alignment accuracy of the pipe ends and reducing welding deviations. The sleeve plate on the inner side of the side plate fixes the hydraulic rod, and the arc-shaped clamping plate at its telescopic end is equipped with a rubber pad. It can clamp the pipes through hydraulic drive. The elastic contact of the rubber pad can not only avoid damage to the pipe surface caused by rigid clamping, but also enhance the clamping stability through uniform pressure, prevent pipe displacement during welding, improve weld quality, and thus achieve the effect of clamping and fixing.

[0010] Preferably, the dust purification component specifically includes: a curved plate, fixedly installed on the top of the base plate; a motor, fixedly installed on one side of the curved plate; a gear, fixedly installed on the output end of the motor; support rods, fixedly installed at equal intervals on the top of the base plate; a bracket ring tube, fixedly installed on the top of the base plate; and a filter box, disposed on the top of the base plate.

[0011] Preferably, a collar is fixedly installed between the inner sides of the support rod, and a gear ring is rotatably connected to one side of the collar. The surface of the gear ring meshes with the surface of the gear. An inner rotating sleeve is fixedly installed on the inner wall of the gear ring, and an electric telescopic rod is fixedly installed on the outer wall of the inner rotating sleeve. The telescopic end of the electric telescopic rod movably penetrates the outer wall of the inner rotating sleeve and extends into the interior of the inner rotating sleeve. A welding head is fixedly installed on the telescopic end of the electric telescopic rod.

[0012] Preferably, suction heads are evenly and equidistantly connected to one side of the support ring tube, a suction pipe is connected between one side of the filter box and the outer wall of the support ring tube, and a suction fan is connected to the other side of the filter box.

[0013] Preferably, gravity blocks are evenly spaced at the top of the filter box, each gravity block has a locking groove at its top, and a retaining frame is fixedly connected to the bottom of each gravity block. The bottom of the retaining frame extends through the top of the filter box and engages with the inner wall of the filter box. A filter screen is fixedly installed between the inner walls of the retaining frame. A motor drives a gear to mesh with a gear ring, causing the inner rotating sleeve to rotate, allowing the welding head to weld around the pipe 360 ​​degrees. The welding head can be extended and retracted by an electric telescopic rod, allowing for precise welding close to the pipe end. The suction heads evenly distributed around the circumference of the support ensure welding at any angle. Under these conditions, fumes and dust can be quickly sucked in by the nearest suction head, preventing the spread of fumes and dust and pollution of the working environment. The suction fan sucks the fumes and dust into the filter box through the suction pipe. The multi-layer filter screen inside the box can filter dust of different particle sizes in sequence. The gravity block design ensures that the filter screen is installed stably and is easy to disassemble and replace. It purifies the harmful fumes and gases generated by welding in real time, reducing the risk of operators inhaling harmful substances. The first layer is a coarse filter screen, which can filter large dust particles. The second layer is a fine filter screen, which filters fine impurities and dust. The third layer is an activated carbon adsorption filter screen, which can adsorb and purify gases, thereby achieving the effect of fume purification.

[0014] This utility model provides a pipe end welding device for seamless pipe fittings. It has the following beneficial effects: (1) This utility model uses a clamping and fixing assembly to fix pipe one and pipe two, ensuring stability during welding. When the pipe is inserted into the sleeve, it can be rotated and the angle of the pipe can be adjusted under the operation of the concave block and roller. After the two pipes are aligned, when it is necessary to fix the pipes, the hydraulic rod is activated to drive the arc plate clamp to fix the pipes. The rubber pad protects the surface of the pipe and activates the anti-slip function, which improves the stability of welding, ensures the alignment accuracy of the pipe ends, reduces welding deviation, and thus achieves the effect of clamping and fixing.

[0015] (2) This utility model purifies the fumes during welding by setting up a fume purification component. The motor is started to drive the gear to rotate, and the gear drives the gear ring and inner rotating sleeve to rotate, which can drive the welding head to perform 360-degree welding. The electric telescopic rod can be started to drive the welding head to weld. The suction fan is started and the suction head absorbs the fumes generated during welding. The fumes enter the filter box through the suction pipe and are filtered and purified through three layers of filter screen. It can collect and treat the fumes and harmful gases generated during welding in a timely and effective manner, improve the working environment, and thus achieve the effect of fume purification.

A welding head 619 is fixedly installed on the telescopic end of the electric telescopic rod 618.

[0027] A suction head 6112 is evenly and equidistantly connected to one side of the support ring tube 6111. A suction pipe 6114 is connected between one side of the filter box 6113 and the outer wall of the support ring tube 6111. A suction fan 6115 is connected to the other side of the filter box 6113.

[0028] Gravity blocks 6116 are evenly spaced on the top of the filter box 6113. The top of the gravity blocks 6116 is provided with a snap-fit ​​groove 6117. The bottom of the gravity blocks 6116 is fixedly connected to a frame 6118. The bottom of the frame 6118 moves through the top of the filter box 6113 and extends to the inner wall of the filter box 6113 to engage with it. A filter screen 6119 is fixedly installed between the inner walls of the frame 6118.

[0029] In this example, the fume purification component 6 is set up to purify the fumes during welding. The motor 612 is started to drive the gear 613 to rotate, and the gear 613 drives the gear ring 616 and the inner rotating sleeve 617 to rotate, which can drive the welding head 619 to perform 360-degree welding.

[0030] Working principle: First, when pipe 3 and pipe 4 need to be fixed, to ensure stability during welding, pipe 3 and pipe 4 are inserted into sleeve 515 and placed on roller 513. Under the action of concave block 512 and roller 513, the pipes can be rotated and the angle of the pipes can be adjusted. After the two pipes are aligned, when it is necessary to fix the pipes, the hydraulic rod 516 is activated to drive the arc plate clamp 517 to fix the pipes.

After fixing is completed, the motor 612 is started to drive the gear 613 to rotate. The gear 613 drives the gear ring 616 and the inner rotating sleeve 617 to rotate, which can drive the welding head 619 to rotate 360 ​​degrees. Welding is performed by activating the electric telescopic rod 618, which drives the welding head 619 to weld the ends of pipes 3 and 4.
