Description

Technical Field

[0001] This utility model relates to the field of weld seam treatment technology, and in particular to a steel structure weld seam treatment device. Background Technology

[0002] Chinese patent application CN202323153449.5 discloses a steel structure weld treatment device, comprising: a base, on which two annular fixing mechanisms for positioning workpieces are symmetrically fitted, a limiting plate is provided between the two annular fixing mechanisms, and a sliding seat is provided on the base, with the limiting plate slidingly engaged with the sliding seat. The advantages of this invention are: the limiting plate slides on the sliding seat, positioned between two steel pipes of the steel structure, to achieve accurate gap spacing, which is beneficial to the welding effect; the limiting plate is easy to disassemble and does not affect subsequent welding; the annular fixing mechanisms can fix the steel pipes of the steel structure; and the inner ring of the annular fixing mechanism has an adjustable diameter semi-ring accessory, allowing for better adaptation to the workpiece diameter by changing the aperture of the annular fixing mechanism.

[0003] The steel pipes in the aforementioned steel structure cannot be rotated after being clamped and fixed by the semi-ring fittings, making it very inconvenient to handle the weld position. Utility Model Content

[0004] To address the shortcomings of the comparative literature, this utility model provides a steel structure weld treatment device, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a steel structure weld treatment device, including a base, a first movable frame and a second movable frame slidably connected to the inner side of the top of the base, a first support and a second support fixedly installed on the inner side of the first movable frame and the second movable frame, and a first fixing block and a second fixing block respectively provided in the middle of the bottom of the inner side of the first movable frame and the second movable frame, a first support roller rotatably connected inside the first support, a second support roller rotatably connected inside the second support, an adjustment mechanism fixedly installed on the top of the first fixing block and the second fixing block being threaded together inside, an electric telescopic rod fixedly installed inside the top of the first movable frame and the second movable frame, a U-shaped frame fixedly installed on the outer side of the bottom end of the electric telescopic rod, a guide rod movably fitted inside the first movable frame and the second movable frame being provided on the top of the U-shaped frame, and a pressure roller rotatably connected inside the U-shaped frame.

[0006] Preferably, the adjustment mechanism includes a first fixing plate and a second fixing plate fixedly installed on the top of the base, and the first fixing plate and the second fixing plate are rotatably connected to a bidirectional lead screw threaded inside the first fixing block and the second fixing block.

[0007] Preferably, the second support roller is internally fitted with a limiting rod that is rotatably connected inside the first and second fixed plates, and the limiting rod is provided with a limiting boss on its outer side that is adapted to the second support roller.

[0008] Preferably, the outer side of the bidirectional lead screw and the limiting rod extending from one end of the second fixing plate is fixedly fitted with a handle.

[0009] This utility model has the following advantages:

[0010] 1. The electric telescopic rod can drive the pressure roller to move downwards and simultaneously fix the steel pipe placed on the first and second support rollers in an axial direction. Since the steel pipe lacks radial restraint, it can be manually rotated around its own axis, making it easier to handle the position of the weld.

[0011] 2. The limit rod and the limit boss work together to radially limit the second support roller installed inside the first and second moving frames, so that when a single steel pipe is rotated, the other steel pipe can be rotated synchronously, so as to adjust the welding position of the two steel pipes synchronously.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 3 A steel structure weld treatment device includes a base 1. A first movable frame 2 and a second movable frame 3 are slidably connected to the inner side of the top of the base 1. A first support 4 and a second support 5 are fixedly installed on the inner sides of both the first movable frame 2 and the second movable frame 3. A first fixing block 6 and a second fixing block 7 are respectively provided at the bottom center of the inner sides of the first movable frame 2 and the second movable frame 3. A first support roller 8 is rotatably connected inside the first support 4, and a second support roller 9 is rotatably connected inside the second support 5. The first support roller 8 and the second support roller 9 can support the steel pipes while ensuring that the steel pipes located inside the first movable frame 2 and the second movable frame 3 are automatically centered. Furthermore, the first support roller 8 and the second support roller 9 can support the steel pipes that are not... Supported by steel pipes of the same outer diameter, the first fixing block 6 and the second fixing block 7 are threaded together with an adjustment mechanism 10 fixedly installed on the top of the base 1. The top of the first moving frame 2 and the second moving frame 3 are both fixedly fitted with electric telescopic rods 11. The outer side of the bottom end of the electric telescopic rod 11 is fixedly fitted with a U-shaped frame 12. The top of the U-shaped frame 12 is provided with a guide rod 13 that is movably fitted inside the first moving frame 2 and the second moving frame 3. The inside of the U-shaped frame 12 is rotatably connected to a pressure roller 14. Driven by the electric telescopic rod 11, the U-shaped frame 12 can be moved along the axial direction of the guide rod 13, while the pressure roller 14 presses the steel pipes placed outside the first support roller 8 and the second support roller 9.

[0018] The adjustment mechanism 10 includes a first fixing plate 101 and a second fixing plate 102 fixedly installed on the top of the base 1. The first fixing plate 101 and the second fixing plate 102 are rotatably connected to a bidirectional screw 103 threaded inside the first fixing block 6 and the second fixing block 7. By rotating the bidirectional screw 103, the first moving frame 2 and the second moving frame 3 can be moved in opposite directions, which facilitates the alignment of the welding ends of the two steel pipes, thereby facilitating the treatment of the weld position of the steel pipes.

[0019] The second support roller 9 is internally fitted with a limiting rod 15 rotatably connected inside the first fixed plate 101 and the second fixed plate 102. The limiting rod 15 has a limiting boss on its outer side that is adapted to the second support roller 9. The limiting boss can limit and guide the second support roller 9, so that the second support roller 9 installed inside the first moving frame 2 and the second moving frame 3 can rotate synchronously when the steel pipe is rotated or the limiting rod 15 is rotated by the handle 16. This ensures that the welded parts of the two steel pipes will not be misaligned when the welded parts of the steel pipes are adjusted.

[0020] Among them, the double-acting lead screw 103 and the limiting rod 15 are both fixedly fitted with handles 16 on the outer side of one end of the second fixed plate 102, so that the double-acting lead screw 103 and the limiting rod 15 can be rotated respectively through the handles 16.

[0021] Working principle: Steel pipes are placed one by one inside the first moving frame 2 and the second moving frame 3, and supported by the first support roller 8 and the second support roller 9. The electric telescopic rod 11 is activated, and the electric telescopic rod 11 drives the pressure roller 14 to move downward along the axial direction of the guide rod 13, while pressing and fixing the steel pipes between the first support roller 8, the second support roller 9 and the pressure roller 14. At this time, the cooperation of the first support roller 8, the second support roller 9 and the pressure roller 14 can automatically position the steel pipes. By rotating the bidirectional screw 103, the first moving frame 2 and the second moving frame 3 can move in opposite directions along the axial direction of the bidirectional screw 103. When the welding end faces of the two steel pipes are aligned, the rotation of the bidirectional screw 103 is stopped, and the steel pipes can be welded. By rotating the steel pipes or rotating the limiting rod 15, the welding position of the steel pipes can be changed. After the steel pipes are welded, the above steps can also be used to adjust the position of the weld seam.
