[0021] Embodiment 1
[0022] like Figure 1 and Figure 2 As shown, a corrugated pipe steel strip welding platform comprises an operating table 1 and a supporting column 2 at the bottom of the operating table 1, and adjustment devices 3 for limiting the width of the steel strip are symmetrically arranged at both ends of the top surface of the operating table 1, and an inverted U-shaped frame 4 is fixedly arranged on the top surface of the operating table 1 near the inner side of each adjustment device 3, and a rotatable guide roller 6 is arranged in each U-shaped frame 4 through a rotating shaft 5, and an inverted U-shaped frame 2 7 that can move up and down is arranged in the U-shaped frame 1 4 corresponding to the guide roller 6, and a pressing roller 8 that is compatible with the guide roller 6 is rotatably arranged in the U-shaped frame 2 7, and the rotating shaft 5 at both ends extends out of the corresponding end of the U-shaped frame 4 and is connected to the output shaft of a motor 11, and the two motors 11 are arranged oppositely;
[0023] Through the above structure, the ends of the steel belts at both ends are passed through the adjusting device 3 and placed between the corresponding guide rollers 6 and the clamping rollers 8, and the motors 11 at both ends are started. Since the motors 11 at both ends are oppositely arranged, the guide rollers 6 at both ends can be driven to rotate in opposite directions, thereby driving the steel belts at both ends to move relative to each other, so that their ends abut against each other.
[0024] like Figure 3 As shown, an inverted U-shaped frame 3 12 is fixedly provided on the top surface of the operating table 1 in the middle between the two U-shaped frames 4, and a sliding seat 14 that can move forward and backward is provided in the U-shaped frame 3 12, and an electric push rod 15 is provided at the end of the bottom surface of the sliding seat 14, and a connecting seat 16 is provided at the movable end of the electric push rod 15, and a welding gun 17 is provided on the connecting seat 16, and the welding gun 17 can be adjusted to move up and down and forward and backward through the electric push rod 15 and the sliding seat 14.
[0025] Through the above structure, under the forward and backward sliding action of the welding gun 17, the abutment of the steel strips at both ends is effectively welded.
[0026] like Figure 2 As shown, the adjusting device 3 includes a sliding seat 19, a support shaft 20 and a guide wheel 21. The top surface of the operating table 1 is symmetrically provided with slide grooves 18 on the front and rear sides respectively. Each slide groove 18 is provided with a sliding seat 19 matched therewith. A support shaft 20 is fixedly provided on the top surface of the sliding seat 19. A guide wheel 21 is rotatably provided on the top surface of each support shaft 20. The operating table 1 is also provided with a linkage device for controlling the two sliding seats 19 at the same end to move relative to or away from each other. The linkage device can simultaneously drive the support shaft 20 and the guide wheel 21 to move relative to or away from each other, thereby adjusting the distance between the guide wheels 21 at both ends and performing limiting operations on steel belts of different widths.
[0027] like Figure 3 As shown, the linkage device includes a threaded barrel 23, a left-handed threaded rod 24 and a right-handed threaded rod 25. Support seats 22 are fixedly provided at both ends of the top surface of the operating table 1 between the two slide grooves 18 at the same end. Threaded barrels 23 are rotated together on the two support seats 22. Internal threads matching the left-handed threaded rod 24 and the right-handed threaded rod 25 are respectively opened at both ends of the inner wall of the threaded barrel 23. The left-handed threaded rod 24 and the right-handed threaded rod 25 are respectively threadedly connected to the two ends of the threaded barrel 23, and the opposite end faces of the left-handed threaded rod 24 and the right-handed threaded rod 25 are respectively fixedly connected to the corresponding support shaft 20. By rotating the threaded barrel 23, the left-handed threaded rod 24 and the right-handed threaded rod 25 are driven to move relative to or away from each other under the positive and negative thread operation at both ends, thereby driving the support shafts 20 and the sliding seat 19 at both ends to move relative to or away from each other for adjustment.
[0028] like Figure 3 As shown, both ends of the inner wall of the U-shaped frame 3 12 are rotated together with an adjusting screw 13, and the adjusting screw 13 is threadedly connected to a sliding seat 14 that slides with the U-shaped frame 3 12. The end of the adjusting screw 13 extending out of the U-shaped frame 3 12 is connected to the output shaft of the motor 2 26. The motor 2 16 is started to drive the adjusting screw 13 to rotate, and the sliding seat 14 is driven to slide back and forth under the operation of the thread force.
[0029] Embodiment 2
[0030] Based on the first embodiment, Figure 1 and Figure 2 As shown, the specific structure of controlling the U-shaped frame 2 7 to slide up and down is as follows:
[0031] An electric cylinder 9 is fixedly provided on the top surface of the U-shaped frame 1 4 at a position corresponding to the middle of the U-shaped frame 2 7. The movable end of the electric cylinder 9 extends into the U-shaped frame 1 4 and is fixedly connected to the top surface of the U-shaped frame 2 7. Guide rods 10 are also respectively penetrated in the U-shaped frame 1 4 corresponding to the two ends of the U-shaped frame 2 7. The bottom ends of the two guide rods 10 are respectively fixedly connected to the corresponding positions on the top surface of the U-shaped frame 2 7. The extension and retraction of the electric cylinder 9 can drive the U-shaped frame 2 7 to slide up and down for adjustment. The setting of the guide rods 10 at both ends can ensure the stability of the U-shaped frame 2 7 during the up and down sliding process.
[0032] In specific use, firstly, the leading and trailing ends of the steel strips at both ends are passed through the adjusting device 3 and placed between the corresponding clamping roller 8 and the guide roller 6, and then the distance between the two guide wheels 21 is adjusted according to the width of the steel strip, and the threaded cylinder 23 is rotated. Under the action of the opposite thread forces at both ends, the left-handed threaded rod 24 and the right-handed threaded rod 25 at both ends are driven to move relative to each other, and at the same time, the support shaft 20 and the guide wheel 21 are driven to move relative to each other, so that the front and rear end surfaces of the steel strip abut against the inner walls of the guide wheels 21 at both ends, and the width of the steel strip is effectively adjusted; then, at the root The height of the clamping roller 8 is adjusted according to the thickness of the steel strip. By controlling the extension of the electric cylinder 9, the clamping roller 8 is driven to move downward so that the upper and lower end surfaces of the steel strip abut against the position between the clamping roller 8 and the guide roller 6. The motors 11 at both ends are started. Since the motors 11 at both ends are set oppositely, the guide rollers 6 at both ends are driven to rotate in opposite directions, and the ends of the steel strips at both ends are driven to move relative to each other for abutment. Finally, the welding gun 17 is adjusted up and down, front and back, and the abutting ends of the two steel strips are effectively welded, thereby improving the scope of use of the device.
[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
