Description

Technical Field

[0001] The invention relates to the field of pressure vessel welding, in particular to a butt joint device for pressure vessel welding. Background Art

[0002] Pressure vessels are sealed containers that withstand internal or external gas or liquid pressure and have strict safety requirements. They primarily carry out reactions, heat transfer, and mass transfer in production, as well as store and transport gases or liquefied gases under pressure. They are widely used in the petroleum, machinery, chemical, energy, scientific research, and national defense industries. They also play an important role in civilian applications such as natural gas or liquefied gas storage tanks and heat exchangers. Pressure vessels are primarily cylindrical, with a few being spherical or other shapes. They typically consist of a body (including the shell, end caps, nozzles, seals, etc.), non-pressure-bearing components (such as supports), safety accessories, and instrumentation. Due to the large internal and external pressure differentials and the potential for toxic, hazardous, or flammable and explosive substances, they are subject to strict standards and regulations. Strict compliance with relevant design standards and guidelines is essential during design, and full attention must be paid to potential unforeseen circumstances during use and operation to avoid safety incidents caused by improper handling.

[0003] While existing docking devices can achieve precise docking after pressure vessels are docked, they present significant drawbacks during the subsequent welding process. Due to the structural characteristics of the pressure vessels and the design limitations of the docking devices, workers face numerous difficulties when performing welding operations. In particular, the narrow space at the bottom of the vessel makes it difficult for workers to maneuver, restricting their operating posture and making it difficult to flexibly use welding tools. This not only reduces welding efficiency but also increases the difficulty of controlling welding quality. Summary of the Invention

The inner wall of the driving rod is slidably connected to the connecting plate, and the grinding wheel is inserted into the right side of the outer wall of the connecting plate. The inner wall of the connecting plate is plugged with a limiting plug, and the right side of the limiting plug is fixedly connected to the driving disk, and the inner wall of the limiting plug is connected to the inner wall of the connecting plate through a limiting assembly for limiting the limiting plug, and the left side of the driving disk abuts against the right side of the grinding wheel.

[0007] Preferably, the transmission assembly includes a first connecting rod fixedly connected to the left end of the driving rod, a second connecting rod fixedly connected to the left end of the rear pulley, the left side of the second connecting rod is rotatably connected to a connecting block, and the right side of the connecting block is rotatably connected to the left side of the first connecting rod.

[0008] Preferably, a gear ring is fixedly connected to the outer wall of the rotating disk, a tooth is fixedly connected to the top end of the first connecting rod, and the outer wall of the gear ring is meshed with the front side of the tooth.

[0009] Preferably, the limiting assembly includes a limiting rotating block rotatably connected to the inner wall of the limiting plug block, the right side of the limiting rotating block abuts against the right side of the outer wall of the connecting plate, and the right side of the limiting rotating block is fixedly connected to a worm gear.

[0010] Preferably, the inner wall of the driving disc is rotatably connected to a worm, and the outer wall of the worm is meshingly connected to the outer wall of the worm wheel.

[0014] Preferably, a plurality of balls are rotatably connected to the inner wall of the second docking sleeve.

[0015] Working principle: When starting work, insert the pressure vessel into the first docking sleeve and the second docking sleeve, and start the electric push rod through the control panel to push the slide plate to slide. The slide plate drives the second docking sleeve to align the two pressure vessels, and the pressure vessels are welded. During the welding process, start the servo motor through the control panel, and the servo motor drives the driving disk to rotate. The rotation of the driving disk drives the limit plug to rotate the grinding wheel to grind the burrs, flashes, curling, etc. on the joints of the pressure vessel, thereby improving the quality of subsequent welding. In addition, during the reset process of each component after welding, the grinding wheel can also grind the weld to increase the aesthetics.

[0016] At the same time, the driving disc drives the connecting plate to rotate, which causes the driving rod to rotate. The rotation of the driving rod drives the first connecting rod to rotate. The rotation of the first connecting rod drags the connecting block to move. The movement of the connecting block drives the second connecting rod to rotate, which causes the rear pulley to rotate. The rotation of the pulley drives the belt strip to move. The movement of the belt strip drives the connecting shell to slide. The sliding of the connecting shell drives the connecting block to slide and clean the waste chips generated during the grinding process back and forth. When the connecting shell slides to the position on the top side of the belt strip, the connecting shell is used to rotate on the belt strip, and because the cleaning brush slides on the left side of the slide plate, it does not affect the movement;

[0017] As the connecting block moves, it drives the teeth to engage with the gear ring to rotate the gear ring. The rotation of the gear ring drives the rotating disk to rotate. The rotation of the rotating disk drives the first docking sleeve to rotate and drives the pressure vessel to rotate. This makes it convenient for workers to weld other parts of the pressure vessel and also makes it convenient for the grinding wheel to grind burrs, flashes, curling, etc. on other joints of the pressure vessel, thereby improving the quality of subsequent welding. In addition, during the reset process of various components after welding, the grinding wheel can also grind the weld to increase the aesthetics.

[0018] When the grinding wheel needs to be removed for replacement, the adjusting knob is turned to rotate the worm, and the rotation of the worm engages with the worm wheel to rotate the worm wheel. The rotation of the worm wheel drives the limit block to retract the inner wall of the limit plug, releasing the limit of the limit block on the inner wall of the drive disk, and sliding the drive disk to remove the grinding wheel for replacement.

[0019] The present invention provides a pressure vessel welding butt joint device, which has the following beneficial effects:

[0020] 1. The present invention drives the teeth to mesh with the gear ring through the movement of the connecting blocks, so that the gear ring rotates. The rotation of the gear ring drives the rotation of the rotating disk. The rotation of the rotating disk drives the first docking sleeve to rotate and drives the pressure vessel to rotate, which is convenient for workers to weld other positions of the pressure vessel and also convenient for the grinding wheel to grind burrs, flashes, curling, etc. on other joints of the pressure vessel, thereby improving the quality of subsequent welding. In addition, during the process of resetting the components after welding, the grinding wheel can also grind the weld to increase the aesthetics.

[0021] 2. The present invention starts the servo motor through the control panel, and the servo motor drives the driving disk to rotate. The rotation of the driving disk drives the limit plug to rotate the grinding wheel, and the burrs, flashes, curling, etc. on the joints of the pressure vessel are ground, thereby improving the quality of subsequent welding. In addition, during the process of resetting the components after welding, the grinding wheel can also grind the weld to improve the aesthetics.

[0022] 3. The present invention drives the connecting plate to rotate by the driving disc to rotate the driving rod, the driving rod rotates and drives the first connecting rod to rotate, the first connecting rod rotates and pulls the connecting block to move, the connecting block movement drives the second connecting rod to rotate and rotate the rear pulley, the pulley rotation drives the belt to move, the belt movement drives the connecting shell to slide, the connecting shell slides and drives the connecting block to slide and clean the waste chips generated during the grinding process back and forth, and discharges the waste generated by grinding from the discharge trough and falls into the collection shell.

[0023] 4. The present invention rotates the worm by turning the adjusting knob, and the rotation of the worm engages with the worm wheel to rotate the worm wheel. The rotation of the worm wheel drives the limit block to retract the inner wall of the limit plug, releasing the limit of the limit block on the inner wall of the drive disk, and sliding the drive disk to quickly remove the grinding wheel for replacement.
