Description

Technical Field

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

[0002] Welded pipes, also known as welded pipes, are made of steel plates or steel strips that are welded after being rolled. Welded pipes have simple production processes, high production efficiency, a wide variety of specifications, and low equipment costs, but their strength is generally lower than that of seamless pipes. Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, the variety and specifications of welded pipes have increased, and they have replaced seamless pipes in more and more fields.

[0003] The application field of welded pipes is wide, and the demand for welded pipes is increasing, and the production efficiency and quality requirements for welded pipes are higher. The traditional welding of pipes is to put the coiled pipes on the support frame, and the joints to be welded are facing upwards to carry out the welding work. However, this fixing method has certain problems, that is, the residual heat time is long when the pipes are welded, especially the thicker the plate, the longer the cooling time is, and the easier it is to oxidize, so it needs to be cooled quickly with water. However, the existing welding frame lacks the collection of cooling water, which causes the cooling water not only to flow randomly, but also to cause waste, so it cannot meet the use requirements. Therefore, a pipe welding frame is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a pipe welding rack, which has the advantages of being highly practical, facilitating the collection of cooling water and preventing it from flowing randomly, and solves the problem that the welding rack lacks the ability to collect cooling water, which causes the cooling water to not only flow randomly but also easily cause waste.

[0005] To achieve the above object, the utility model provides the following technical solutions: a pipe welding rack, comprising a collection box for collecting cooling water, a welding rack for supporting the pipeline is arranged above the collection box, and a shielding structure is arranged inside the collection box;

[0008] Furthermore, the bottom end of the telescopic rod extends into the supporting column, and adjustment holes are provided inside the telescopic rod and the supporting column, and an adjustment rod is installed in the adjustment hole.

[0009] Furthermore, fixed platforms are welded on the left and right outer walls of the collection box, the number of the welding frames is four, and four supporting columns are symmetrically fixed on the upper surfaces of the two fixed platforms in a rectangular shape.

[0010] Furthermore, the number of mounting seats in the shielding structure is four, the number of shielding plates and connecting rods is two, and the two shielding plates are rotatably mounted between the four mounting seats, and the two connecting rods are arranged in a V shape.

[0011] Furthermore, the front and rear sides of the two shielding plates are fixedly mounted with shift rods, and when the shielding plates are parallel to the collection box, the shift rods abut against the upper surface of the collection box.

[0012] Furthermore, a disassembly opening communicating with the outside is provided inside the collection box, and a filter screen extending to the inside of the collection box is slidably installed in the disassembly opening.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-3 A pipe welding frame includes a collecting box 1 for collecting cooling water, a welding frame for supporting the pipeline is arranged above the collecting box 1, and the welding frame includes a supporting column 3, a telescopic rod 4 that slides and extends to the outside of the supporting column 3, a wheel frame 5 welded to one end of the telescopic rod 4, and a supporting guide wheel 6 rotatably installed on the outside of the wheel frame 5.

[0026] In this embodiment, a shielding structure is provided in the collecting box 1; the shielding structure includes a mounting base 8 fixedly mounted on the upper surface of the collecting box 1, a shielding plate 9 rotatably mounted on the mounting base 8, a servo motor 10 fixedly mounted inside the collecting box 1, a crank 11 fixedly mounted on the output shaft of the servo motor 10, and a connecting rod 12 hinged to the other end of the crank 11 and the lower surface of the shielding plate 9.

[0027] It should be noted that the number of mounting seats 8 in the shielding structure is four, the number of shielding plates 9 and connecting rods 12 is two, and the two shielding plates 9 are rotatably mounted between the four mounting seats 8, and the two connecting rods 12 are arranged in a V shape.

[0028] In order to enable the shielding plates 9 to be placed horizontally with the collection box 1, the front and rear sides of the two shielding plates 9 are fixedly installed with levers 14. When the shielding plates 9 are parallel to the collection box 1, the levers 14 abut against the upper surface of the collection box 1. The installation of the levers 14 effectively prevents the shielding plates 9 from being placed tilted.

[0029] In addition, a disassembly opening 19 connected to the outside is provided inside the collection box 1, and a filter screen 13 extending to the inside of the collection box 1 is slidably installed inside the disassembly opening 19. The cooling water is filtered through the filter screen 13 so that it can be better collected and used later. A handle is fixedly connected to the outside of the filter screen 13 to facilitate the removal of the filter screen 13 from the inside of the collection box 1 for cleaning.

[0030] When this embodiment is in use, the servo motor 10 drives the crank 11 and the connecting rod 12 to realize the rotation adjustment of the baffle plate 9, so that the top of the collection box 1 can be blocked or opened. When the baffle plate 9 is closed, the residue during the welding seam can be effectively prevented from entering the collection box 1. When the baffle plate 9 is opened, the cooling water can be collected.

[0031] Embodiment 2:

[0032] See also Figure 1 On the basis of the first embodiment, four casters 15 distributed in a rectangular shape are rotatably mounted on the lower surface of the collection box 1, and a supporting device is provided on the side wall of the collection box 1. The supporting device includes a mounting box 16 fixedly mounted on the side wall of the collection box 1, a hydraulic cylinder 17 fixedly mounted inside the mounting box 16, and a supporting block 18 fixedly mounted on the output end of the hydraulic cylinder 17.

The number of the supporting devices is four, and the four supporting devices are arranged in a rectangular shape.

[0034] By adopting the above technical solution, the collection box 1 can be moved, the maneuverability of the collection box 1 can be improved, and at the same time, the collection box 1 can be supported to ensure the stable placement of the pipes.

[0035] The working principle of the above embodiment is:

[0036] The support guide wheel 6 is raised and lowered by the adjusting rod 7 so that the pipe can be placed better. When in use, the crank 11 and the connecting rod 12 are driven by the servo motor 10 to realize the rotation adjustment of the baffle plate 9, so that the top of the collection box 1 can be blocked or opened. When the baffle plate 9 is closed, the residue from the welding seam can be effectively prevented from entering the collection box 1. When the baffle plate 9 is opened, the cooling water can be collected and then filtered through the filter net 13, so that the cooling water can be better collected and used later.
