Description

Technical Field

[0001] The utility model belongs to the technical field of galvanized welded pipe processing, in particular to a turning device for galvanized welded pipes. Background Art

[0002] In order to improve the corrosion resistance of steel pipes, galvanized welded pipes are generally used for galvanizing. Galvanized welded pipes are divided into hot-dip galvanizing and cold-dip galvanizing. Hot-dip galvanizing has a thick zinc layer and good effect, while cold-dip galvanizing has a low cost. However, the zinc layer on the surface of the steel pipe is thin and the corrosion resistance is poor. Therefore, hot-dip galvanizing is generally used to galvanize steel pipes.

[0003] When two groups of galvanized welded pipes are welded together, the welding gun can generally only weld the upper position of the galvanized welded pipes, while the lower position is blocked and cannot be welded. Therefore, the two groups of galvanized welded pipes need to be turned over from top to bottom. Generally, the two groups of galvanized welded pipes are turned over from top to bottom synchronously manually. However, it is difficult to ensure that the two groups of galvanized welded pipes move synchronously, which can easily cause cracks in the welded positions of the two groups of galvanized welded pipes. At the same time, the safety of personnel approaching the welding position to adjust the galvanized welded pipes is also low. Utility Model Content

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a turning device for galvanized welded pipes, such as Figure 1-5As shown, the turning device for galvanized welded pipes includes: a base 1; a plurality of first electric telescopic rods 2, which are fixedly mounted on the top of the base 1; two fixed plates 3, which are respectively fixedly mounted on the output rods of the plurality of first electric telescopic rods 2; two mounting frames 4, which are respectively fixedly mounted on the two fixed plates 3, and the two mounting frames 4 are rotatably mounted with driving rollers 6 in contact with the galvanized welded pipes; two motors 5, which are respectively mounted on the two mounting frames 4, and the output shafts of the two motors 5 are respectively connected to the two driving rollers 6; and a plurality of support assemblies, which are all mounted on the base 1 and are used to clamp the galvanized welded pipes.

[0024] In this embodiment, the base 1 serves as the supporting basis of the entire flipping device, and its stability and load-bearing capacity are crucial to the normal operation of the device. The main function of the multiple first electric telescopic rods 2 is to drive the fixed plate 3 to move up and down by telescoping, thereby realizing the flipping of the welded pipes limited to different heights. The function of the mounting frame 4 is to support and fix the driving roller 6 to ensure that it can stably drive the welded pipe to rotate when rotating, thereby realizing the flipping of the galvanized welded pipe. The rotation of the motor 5 is converted into the rotational motion of the welded pipe through the driving roller 6, thereby realizing the flipping of the welded pipe.

[0025] In a further preferred embodiment of the utility model, the support assembly includes a support ring 7, multiple second electric telescopic rods 8, multiple limit blocks 9, multiple balls 10 and multiple anti-slip pads 11, the support ring 7 is fixedly mounted on the top of the base 1, the multiple second electric telescopic rods 8 are all fixedly mounted on the support ring 7, the multiple limit blocks 9 are respectively fixedly mounted on the output rods of the multiple second electric telescopic rods 8, and the multiple balls 10 and the multiple anti-slip pads 11 are respectively mounted on the side where the multiple limit blocks 9 are close to each other.

[0026] In this embodiment, the support ring 7 provides a position for installing the second electric telescopic rod 8 and ensures the stability of the entire support assembly. The second electric telescopic rod 8 adjusts the position of the limit block 9 by telescoping to adapt to galvanized welded pipes of different sizes. When the welded pipe is placed on the support assembly, the second electric telescopic rod 8 can adjust its length as needed so that the limit block 9 can tightly clamp the welded pipe to prevent it from slipping or moving during the flipping process. The function of the ball 10 is to reduce the friction between the limit block 9 and the welded pipe so that the welded pipe can move more smoothly during the flipping process. The anti-slip pad 11 is used in conjunction with the ball 10. When the welded pipe needs to be firmly fixed on the support assembly, the anti-slip pad 11 can provide additional friction to increase the stability of the welded pipe.

[0027] In a further preferred embodiment of the utility model, two electric guide rails 12 are installed on the top of the base 1, and the moving parts of the two electric guide rails 12 are fixedly installed with limit frames 13, and the two limit frames 13 are rotatably installed with support shafts 17. The two sides of the two support shafts 17 close to each other are fixedly installed with clamps 14, and the two clamps 14 can respectively contact the two sections of galvanized welded pipes to be welded.

[0028] In this embodiment, the electric guide rail 12 realizes linear movement of the moving part through electric drive. This design enables the support shaft 17 and the clamp 14 to be moved to the specified position as needed to adapt to galvanized welded pipes of different sizes and positions. The rotation function of the support shaft 17 enables the clamp 14 to adapt to galvanized welded pipes of different angles, further enhancing the flexibility and applicability of the equipment. The design of the clamp 14 enables it to tightly clamp the welded pipe to prevent the movement or shaking of the welded pipe during flipping or welding, thereby improving the accuracy and quality of welding.

[0029] In a further preferred embodiment of the utility model, a reducer 16 is fixedly installed on the output shafts of the two motors 5, the two driving rollers 6 are fixedly connected to the two reducers 16 respectively, and rubber pads are fixedly sleeved outside the two driving rollers 6.

[0030] In this embodiment, the main function of the reducer 16 is to reduce the output speed of the motor 5 and increase the output torque at the same time, which means that when driving the welded pipe to flip, the driving roller 6 can obtain a larger rotational torque, thereby driving the welded pipe to flip more stably and reliably. In addition, reducing the speed can also reduce the noise and wear caused by high-speed rotation, further extending the service life of the equipment. The rubber pad is soft and has a certain friction force, which can ensure close contact with the welded pipe and avoid sliding or slipping between the welded pipe and the driving roller 6 during the flipping process. This can not only improve the stability and accuracy of the flipping, but also protect the surface of the welded pipe from scratches or wear.

[0031] In a further preferred embodiment of the utility model, two mounting plates are fixed to the bottom of the two limit frames 13, and moving wheels 15 are rotatably installed on both sides of multiple mounting plates, and multiple moving wheels 15 are in contact with the top of the base 1.

[0032] In this embodiment, the mounting plate provides an installation base for the moving wheel 15, so that the limit frame 13 can slide on the base 1 through the moving wheel 15. The design of the moving wheel 15 enables the limit frame 13 to be easily moved on the base 1, thereby facilitating the adjustment of the distance between the two limit frames 13 to accommodate galvanized welded pipes of different lengths.

[0033] In a further preferred embodiment of the present invention, a plurality of adjusting beads 18 are embedded on the sides of the two clamping plates 14 that are away from each other, and the plurality of adjusting beads 18 are respectively in contact with the sides of the two limiting frames 13 that are close to each other.

[0034] In this embodiment, by adjusting the contact between the bead 18 and the limit frame 13, the clamping plate 14 can obtain more stable support when clamping the galvanized welded pipe. This design can reduce the shaking caused by unstable clamping, thereby ensuring the accuracy and safety of the welding process.

[0035] In a further preferred embodiment of the utility model, welding spaces are provided between the plurality of support rings 7 , scale lines are provided on the sides of the two limit frames 13 away from each other, and pointers pointing to the scale lines are provided on the two support shafts 17 .

[0036] In this embodiment, the welding space is designed to provide sufficient space for welding operations when the galvanized welded pipe is clamped and fixed between multiple limit frames 13. By reading the scale line indicated by the pointer, the operator can quickly and accurately determine the rotation angle of the welded pipe.

[0037] To sum up, compared with the related technology, the present device can clamp and limit the galvanized welded pipe by setting a support component, can drive the galvanized welded pipe to flip by setting a motor 5 in cooperation with a driving roller 6, and can pressurize the two sections of galvanized welded pipe by setting a limit frame 13 in cooperation with a clamping plate 14, so that the two welded pipes are in direct contact, thereby increasing welding stability.
