Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel pipe welding, in particular to a galvanized steel pipe rapid welding device. Background Art

[0002] Galvanized steel pipes are divided into cold-dip galvanized steel pipes and hot-dip galvanized steel pipes. The surface of galvanized steel pipes has a hot-dip or electroplated zinc layer. Galvanizing can increase the corrosion resistance of the steel pipe and extend its service life. When processing galvanized steel pipes, welding is often used to combine two galvanized steel pipes.

[0003] When the existing galvanized steel pipe rapid welding device is used, it is not possible to automatically load the galvanized steel pipe to be processed or unload the galvanized steel pipe after welding, resulting in that the welding operation cannot be carried out continuously, thereby affecting the welding efficiency.

[0004] Therefore, in order to solve the problem that the above-mentioned existing galvanized steel pipe quick welding device is inconvenient to load and unload during use, a galvanized steel pipe quick welding device can be designed. The galvanized steel pipe can be transported by setting a conveyor belt, and then the mechanical clamp is clamped, and the turntable rotates, so that the support arm drives the mechanical clamp to rotate upward, thereby driving the two galvanized steel pipes to be welded to the working position of the welding module for welding. After the welding is completed, the turntable continues to rotate in the original direction, and the mechanical clamp drives the galvanized steel pipe to move to the back side of the entire device, and then releases it for unloading. Utility Model Content

[0005] In order to overcome the problem that the existing galvanized steel pipe rapid welding device cannot automatically load the galvanized steel pipe to be processed and unload the galvanized steel pipe after welding, which affects the welding efficiency.

[0006] The technical solution of the utility model is: a galvanized steel pipe rapid welding device, comprising two base plates; also comprising a conveyor belt, an electric guide rail, a mounting plate, a pillar, a turntable, a drive motor, a support arm and a mechanical clamp, the upper surfaces of the two base plates are provided with a support beam, a cylinder is provided at the middle position of the bottom surface of the crossbeam of the support beam, a welding module is installed at the telescopic end of the cylinder, a mutually symmetrical conveyor belt is provided on the front ground of the support beam, an electric guide rail is provided on the rear ground of the support beam, the upper surface of the electric guide rail is connected to the mutually symmetrical mounting plates through an electric slider, a pillar is provided on one side of the upper surface of the two mounting plates near the end of the electric guide rail, the top position of the pillar is connected to the drive motor, the output end of the drive motor is connected to the turntable, one end of the support arm is installed on the outer surface of the turntable, and the other end of the support arm is installed with a mechanical clamp.

[0007] Preferably, a conveyor belt can be set up to transport the galvanized steel pipes that need to be welded. When the galvanized steel pipes are transported to the end of the conveyor belt, they will fall on the surface of the mechanical clamp and be clamped by the mechanical clamp. Then the drive motor is started, and its output end drives the turntable to rotate, so that the support arm drives the mechanical clamp to rotate upward, thereby driving the two galvanized steel pipes that need to be welded to the working position of the welding module for welding. After the welding is completed, the turntable continues to rotate in the original direction, and the mechanical clamp drives the welded galvanized steel pipes to move to the back side of the entire device, and then releases it for unloading. This solves the problem that the existing galvanized steel pipe rapid welding device cannot continuously load and unload during use, and needs to be repeatedly installed and positioned, which affects the welding speed.

[0008] Preferably, symmetrical bases are provided on the ground in front of the electric guide rail, and an electric push rod is installed on the upper surface of the base. The telescopic end of the electric push rod is connected to the support assembly. By setting the electric push rod, after the galvanized steel pipe to be welded is moved to the welding position, the telescopic end of the electric push rod will push the support assembly upward, thereby supporting and positioning the bottom of the two galvanized steel pipes, thereby improving the welding accuracy.

[0009] Preferably, the support assembly includes a support claw, a driving shaft and a servo motor; the telescopic end of the electric push rod is connected to the support claw, the inner surface of the support claw is rotatably connected to the middle position on the left and right sides of the support claw, and the servo motor is installed on the side surface of the support claw, and the output end of the servo motor is connected to the driving shaft. By setting up the servo motor, its output end will drive the driving shaft to rotate during operation, and the outer surface of the driving shaft will contact the outer surface of the galvanized steel pipe, thereby driving the galvanized steel pipe to rotate synchronously during rotation, thereby facilitating the adjustment of the welding position.

[0010] Preferably, the support assembly also includes a driven shaft, and the front and rear sides of the inner surface of the support claw are rotatably connected with mutually symmetrical driven shafts. The driven shaft has the same diameter as the driving shaft. By setting the driven shaft, when the galvanized steel pipe rotates, the two driven shafts will provide support and drive for the galvanized steel pipe while assisting the galvanized steel pipe to rotate, thereby improving the stability of the rotation of the galvanized steel pipe.

[0011] Preferably, symmetrical fixed blocks are installed on the rear side of the bottom surface of the frame of the two conveyor belts, and a material guide plate is welded on the rear surface of the fixed block. Through the provided material guide plate, after the galvanized steel pipe moves to the end position of the conveyor belt, it will fall on the surface of the material guide plate and slide into the inside of the mechanical clamp through the material guide plate, thereby ensuring the accuracy of loading and preventing the galvanized steel pipe from falling.

[0012] Preferably, support rods are installed on the side of the upper surface of the two mounting plates away from the pillars, and the top ends of the support rods are rotatably connected to the turntable. By setting up the support rods, support can be provided to the turntable and assistance can be provided to the pillars, thereby improving the stability of the turntable rotation.

[0013] Preferably, the telescopic end of the electric push rod is welded to the bottom surface of the support claw. By fixing the support claw by welding, the fixing strength between the support claw and the telescopic end of the electric push rod can be improved to avoid loosening.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a conveyor belt, the galvanized steel pipes that need to be welded can be transported. When they are transported to the end of the conveyor belt, the galvanized steel pipes will fall on the surface of the mechanical clamp and be clamped by the mechanical clamp. Then the drive motor is started, and its output end drives the turntable to rotate, so that the support arm drives the mechanical clamp to rotate upward, thereby driving the two galvanized steel pipes that need to be welded to the working position of the welding module for welding. After welding is completed, the turntable continues to rotate in the original direction, and the mechanical clamp drives the welded galvanized steel pipes to move to the back side of the entire device, and then releases it for unloading. This solves the problem that the existing galvanized steel pipe rapid welding device cannot continuously load and unload during use, and needs to be repeatedly installed and positioned, which affects the welding speed.

The galvanized steel pipe that needs to be welded can be transported by setting the conveyor belt 5. When the galvanized steel pipe is transported to the end of the conveyor belt 5, it will fall on the surface of the mechanical clamp 13 and be clamped by the mechanical clamp 13, and then the drive motor 11 is started, and its output end drives the turntable 10 to rotate, so that the support arm 12 drives the mechanical clamp 13 to rotate upward, thereby driving the two galvanized steel pipes that need to be welded to the working position of the welding module 4 for welding. After the welding is completed, the turntable 10 continues to rotate in the original direction, and the mechanical clamp 13 drives the welded galvanized steel pipe to move to the rear side of the entire device, and then releases it for unloading.

[0023] See also Figure 1-Figure 3In this embodiment, a mutually symmetrical base 14 is provided on the ground in front of the electric guide rail 6. An electric push rod 15 is installed on the upper surface of the base 14. The telescopic end of the electric push rod 15 is connected to a support assembly. By setting the electric push rod 15, after the galvanized steel pipe to be welded is moved to the welding position, the telescopic end of the electric push rod 15 will push the support assembly to lift up, thereby supporting and positioning the bottom of the two galvanized steel pipes, improving the welding accuracy. The support assembly includes a support claw 161, a driving shaft 162 and a servo motor 163; the telescopic end of the electric push rod 15 is connected to the support claw 161, and the middle position of the left and right sides of the inner surface of the support claw 161 is rotatably connected to the driving shaft 162, and the side surface of the support claw 161 is installed with a servo motor 163. The output end of the servo motor 163 is connected to the driving shaft 162. By setting up the servo motor 163, its output end will drive the driving shaft 162 to rotate during operation. The outer surface of the driving shaft 162 contacts the outer surface of the galvanized steel pipe, thereby driving the galvanized steel pipe to rotate synchronously during rotation, thereby facilitating adjustment of the welding position. The support assembly also includes a driven shaft 164. The front and rear sides of the inner surface of the support claw 161 are rotatably connected with mutually symmetrical driven shafts 164. The driven shaft 164 has the same diameter as the driving shaft 162. By setting up the driven shaft 164, when the galvanized steel pipe rotates, the two driven shafts 164 will provide support and drive to the galvanized steel pipe while assisting the galvanized steel pipe to rotate, thereby improving the stability of the rotation of the galvanized steel pipe.

[0024] See also Figures 1-4 In this embodiment, symmetrical fixing blocks 17 are installed at the rear side of the bottom surface of the frame of the two conveyor belts 5, and a guide plate 18 is welded on the rear surface of the fixing block 17. Through the provided guide plate 18, after the galvanized steel pipe moves to the end position of the conveyor belt 5, it will fall on the surface of the guide plate 18 and slide into the inside of the mechanical clamp 13 through the guide plate 18, thereby ensuring the accuracy of loading and preventing the galvanized steel pipe from falling. A support rod 9 is installed on the side of the upper surface of the two mounting plates 7 away from the pillar 8. The top of the support rod 9 is rotatably connected to the turntable 10. By providing the support rod 9, support can be provided to the turntable 10 and assistance can be provided to the pillar 8, thereby improving the stability of the rotation of the turntable 10. The telescopic end of the electric push rod 15 is welded to the bottom surface of the support claw 161. By fixing the support claw 161 by welding, the fixing strength between the support claw 161 and the telescopic end of the electric push rod 15 can be improved to avoid loosening.

[0025] During operation, by setting an electric push rod 15, after the galvanized steel pipe to be welded moves to the welding position, the telescopic end of the electric push rod 15 will push the support assembly to lift up, thereby supporting and positioning the bottoms of the two galvanized steel pipes, improving the welding accuracy, and by setting a servo motor 163, its output end will drive the active shaft 162 to rotate during operation, and the outer surface of the active shaft 162 contacts the outer surface of the galvanized steel pipe, thereby driving the galvanized steel pipe to rotate synchronously during rotation, thereby facilitating the adjustment of the welding position, and by setting a driven shaft 164, when the galvanized steel pipe rotates, the two driven shafts 164 will provide support for the galvanized steel pipe. The support drives and assists the galvanized steel pipe to rotate at the same time, thereby improving the stability of the rotation of the galvanized steel pipe, and through the provided guide plate 18, after the galvanized steel pipe moves to the end position of the conveyor belt 5, it will fall on the surface of the guide plate 18, and slide into the inside of the mechanical clamp 13 through the guide plate 18, thereby ensuring the accuracy of loading and preventing the galvanized steel pipe from falling, and by providing the support rod 9, it can provide support for the turntable 10 and provide assistance for the pillar 8, thereby improving the stability of the rotation of the turntable 10, and by fixing the support claw 161 by welding, the fixing strength between the support claw 161 and the telescopic end of the electric push rod 15 can be improved to avoid loosening.

[0026] Through the above steps, the galvanized steel pipes that need to be welded can be transported by setting up a conveyor belt 5. When the galvanized steel pipes are transported to the end of the conveyor belt 5, they will fall on the surface of the mechanical clamp 13 and be clamped by the mechanical clamp 13. Then the drive motor 11 is started, and its output end drives the turntable 10 to rotate, so that the support arm 12 drives the mechanical clamp 13 to rotate upward, thereby driving the two galvanized steel pipes that need to be welded to the working position of the welding module 4 for welding. After the welding is completed, the turntable 10 continues to rotate in the original direction, and the mechanical clamp 13 drives the welded galvanized steel pipes to move to the back side of the entire device, and then releases it for unloading. This solves the problem that the existing galvanized steel pipe rapid welding device cannot continuously load and unload during use, and needs to be repeatedly installed and positioned, affecting the welding speed.
