Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding equipment for steam-buried insulated steel pipes. Background Technology

[0002] Insulated steel pipes are steel pipes that have undergone insulation processing to ensure that the internal temperature and surface temperature of the working steel pipe meet or reach the required usage temperature under different working environments and external media. Insulated pipes are widely used in liquid and gas transmission networks, chemical pipeline insulation projects, petroleum, chemical, district heating networks, central air conditioning ventilation ducts, municipal engineering, etc.

[0003] In the process of using insulated steel pipes, it is often necessary to weld two insulated steel pipes together. Traditionally, manual welding is often used, which can easily lead to misalignment of the two insulated steel pipes during welding, resulting in welding errors. At the same time, the welding area of ​​the insulated steel pipes needs to be cleaned before welding to improve the welding effect.

[0004] Therefore, a steam-buried insulated steel pipe welding equipment is needed. This equipment can be adjusted according to the different thicknesses of the insulated steel pipes, facilitating the clamping and transfer of the insulated steel pipes to be welded. The equipment can automatically align two insulated steel pipes to be welded, eliminating misalignment errors that occur during manual welding and ensuring welding efficiency. The equipment can simultaneously wipe and clean the ends of the two insulated steel pipes to be welded, ensuring the welding effect. The equipment can automatically weld two insulated steel pipes, improving work efficiency while saving manpower. Summary of the Invention

[0046] like Figure 14 As shown, a sponge is installed on the front side of the cleaning plate 406.

A spring is installed on the rear side of the cleaning plate 406, and the other end of the spring is connected to the curved plate on the side of the C-shaped frame II 402.

[0047] Working principle:

[0048] When adapting to different thicknesses of insulated steel pipes, the electric cylinder I109 operates, driving the rack at the piston rod end of the electric cylinder I109 to move. The rack drives the two circular plates 108 to rotate, and the two circular plates 108 drive the horizontal plate 105 to move up and down. The horizontal plate 105 drives the three electric wheels 106 on it to simultaneously contact the lower end of the insulated steel pipe, adapting to different thicknesses of insulated steel pipes. At the same time, when the driven wheels on the four limiting plates 112 adapt to the thickness of the insulated steel pipe, the motor I115 starts, driving the two gears I114 to rotate. The two gears I114 drive the two discs 113 to rotate respectively. The two discs 113 then drive the two limiting plates 112 sliding on their two inclined grooves to move inward simultaneously, so that the driven wheels on the limiting plates 112 contact the insulated steel pipe.

[0049] When the insulated steel pipe is moved, the three electric wheels 106 work and drive the insulated steel pipe to move. At this time, the driven wheels on the four limiting plates 112 adapt to assist the movement of the insulated steel pipe, so that the two insulated steel pipes that need to be welded are connected, that is, the clamping of the insulated steel pipe can be completed automatically, saving manpower.

[0050] When the two insulated steel pipes are aligned, the camera on the upper plate 103 monitors whether the two insulated steel pipes are aligned and transmits the information to the motor on the side of the U-shaped frame 101. The motor on the side of the U-shaped frame 101 adjusts the position of the base plate 102, thereby adjusting the position of the two insulated steel pipes. During adjustment, the motor on the side of the U-shaped frame 101 starts, driving the electric wheel 106 to rotate. The electric wheel 106 drives the base plate 102 to move left and right to adjust the position of the insulated steel pipes, so that the two insulated steel pipes are automatically aligned, eliminating the misalignment error that occurs when the insulated steel pipes are manually welded and ensuring welding efficiency.

[0051] During the cleaning process before welding the insulated steel pipes, the electric cylinder II 204 operates, driving the rack at the piston rod end to move, which in turn drives the gear II 203 to rotate. The gear II 203 drives the limiting frame 202 to rotate, and the limiting frame 202 drives the bending frame II 401 to move forward, so that the semi-circular frame on the bending frame II 401 moves to a position concentric with the insulated steel pipe to be welded. At this time, the sponge on the side of the cleaning plate 406 simultaneously contacts the inner ends of the two insulated steel pipes. Then, the motor III 405 starts, driving the vertical rod II 404 to rotate. The vertical rod II 404 drives the two gears IV 403 to rotate simultaneously. The gears IV 403 drive the C-shaped frame II 402 to rotate one revolution. The C-shaped frame II 402 drives the vertical rod II 404 to rotate one revolution around the insulated steel pipe. The sponge on the side of the cleaning plate 406 wipes the inner ends of the two joined insulated steel pipes clean, ensuring that the subsequent welding can proceed smoothly.

[0052] When welding the insulated steel pipe, the electric cylinder II 204 operates, driving the rack at the piston rod end to move, which in turn drives the gear II 203 to rotate. The gear II 203 drives the limiting frame 202 to rotate, which in turn drives the bending frame II 401 to move backward and simultaneously drives the bending frame I 301 to move forward, so that the semi-circular frame on the bending frame I 301 is moved to a position concentric with the insulated steel pipe to be welded. Then, the lead screw and slider assembly 306 operates, driving the welding machine 307 to move downward, so that the welding machine 307... The welding head moves to the joint of the two insulated steel pipes. Then, motor II 305 starts, driving vertical rod I 304 to rotate. Vertical rod I 304 drives two gears III 303 to rotate simultaneously. Gears III 303 drive C-shaped frame I 302 to rotate one revolution. C-shaped frame I 302 drives screw and slider assembly 306 to rotate one revolution. Screw and slider assembly 306 drives welding machine 307 to rotate one revolution.
