Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe welding technology, specifically to a stainless steel pipe branch pipe welding equipment. Background Technology

[0002] During pipeline construction and installation, different factory equipment will use pipes of different diameters according to different usage requirements. Sometimes, it is also necessary to weld multiple branch pipes evenly on the main pipe. In traditional welding methods, when it is necessary to weld branch pipes on the main pipe, clamps are usually used to temporarily clamp and fix the branch pipes, and then the operators manually complete the welding operation between the main pipe and the branch pipes.

[0003] While this method can achieve basic welding functions, it has many limitations in actual operation. The vibration and reaction forces generated during welding often cause the branch pipe position to shift, especially when welding multiple branch pipes consecutively. This shift is more pronounced, and even small changes caused by the branch pipe position shift can seriously affect the welding accuracy, thereby reducing the stability and safety of the entire pipeline system.

[0004] Therefore, it is necessary to design a stainless steel pipe branch welding equipment to improve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] This utility model provides a stainless steel pipe branch welding device, which aims to solve the technical problem that the stability of the existing clamp-assisted branch welding is poor, which easily causes the branch position to shift and affects the welding accuracy.

[0027] Please see Figures 1-5 This embodiment provides a stainless steel pipe branch welding device, including a limiting frame 1. An adjusting screw 101 is rotatably connected inside the limiting frame 1. A motor 1011 is installed on one end of the adjusting screw 101 outside the limiting frame 1. The output end of the motor 1011 is fixedly connected to one end of the adjusting screw 101.

[0028] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 An adjusting frame 2 is slidably connected inside the limiting frame 1. The adjusting frame 2 consists of a sliding frame 201, directional pulleys 202, an electric telescopic rod 203, and an adjusting platform 204. A threaded adjusting hole 2011 is provided on the sliding frame 201 at a position corresponding to the adjusting screw 101. The motor 1011 drives the adjusting screw 101 to rotate, so that the sliding frame 201 is threadedly connected to the adjusting screw 101 through the threaded adjusting hole 2011. This causes the branch pipe clamped at the top of the branch pipe clamping frame 3 to dock with the main pipe clamped at the top of the main pipe clamping frame 4. A set of directional pulleys 202 are rotatably connected to both sides of the bottom of the sliding frame 201. The directional pulleys 202 improve the smoothness of the sliding displacement of the sliding frame 201. For stability, a set of electric telescopic rods 203 are installed on both sides of the top of the sliding frame 201. An adjustment platform 204 is fixedly connected to the top of the two sets of electric telescopic rods 203. The electric telescopic rods 203 push the support pipe at the top of the support pipe clamp 3 to adjust the height according to the welding position through the adjustment platform 204. A guide groove 2041 is opened inside the adjustment platform 204 between the two sets of electric telescopic rods 203. An adjustment screw 2042 is rotatably connected inside the guide groove 2041. A motor 2043 is installed at one end of the adjustment screw 2042 on the outside of the adjustment platform 204. A set of directional sliding grooves 2044 are opened on both sides of the top of the adjustment platform 204 on the guide groove 2041.

[0029] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A branch pipe clamping frame 3 is slidably connected to the top of the adjusting frame 2. A threaded adjusting hole 301 is provided on the bottom side of the branch pipe clamping frame 3, corresponding to the adjusting screw 2042. The motor 2043 drives the adjusting screw 2042 to rotate, causing the branch pipe clamping frame 3 to be threadedly connected to the adjusting screw 2042 through the threaded adjusting hole 301. This allows the branch pipe to be adjusted left and right on the adjusting table 204 according to the welding position, improving the convenience of welding adjustment between the branch pipe and the main pipe. Pulley groups are rotatably connected to both sides of the bottom of the branch pipe clamping frame 3, corresponding to the directional sliding groove 2044. The branch pipe clamping frame 3 is slidably connected to the directional sliding groove 2044 through the pulley groups, improving the left and right displacement adjustment of the branch pipe clamping frame 3. To ensure the smoothness of the joint, a fixed frame 302 is fixedly connected to the top of the branch pipe clamping frame 3. An electric cylinder 303 is installed on the top of the fixed frame 302. The output end of the electric cylinder 303 is located below the fixed frame 302 and is fixedly connected to a clamping component 304. A set of triangular clamping grooves 305 are opened between the clamping component 304 and the branch pipe clamping frame 3 on the corresponding side. A rubber anti-slip pad is adhered to the inner wall of the triangular clamping groove 305. The controller 5 controls the electric cylinder 303 to push the clamping component 304 down through the wire. The branch pipe is clamped and positioned by the triangular clamping groove 305 according to the cross-sectional size of the branch pipe. The rubber anti-slip pad enhances the anti-slip performance of the triangular clamping groove 305 in clamping the branch pipe.

[0030] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 Two sets of main pipe clamping frames 4 are fixedly connected to the left side of the limiting frame 1. A set of limiting slide rods 401 are fixedly connected to the top of the front main pipe clamping frame 4 on both sides. A limiting plate 402 is fixedly connected between the limiting slide rods 401. An electric cylinder 403 is installed on the top of the limiting plate 402. A pipe clamping component 404 is fixedly connected to the output end of the electric cylinder 403 below the limiting plate 402. Guide sliding holes 4041 are opened on both sides of the pipe clamping component 404 at positions corresponding to the limiting slide rods 401. The pipe clamping component 404 is connected to the limiting slide rods 401 through the guide sliding holes 4041. The sliding connection of the sliding rod 401 improves the smoothness and stability of the sliding clamping of the pipe clamping component 404. The pipe clamping component 404 and the main pipe clamping frame 4 are provided with triangular clamping grooves 4042 on the corresponding side. The inner wall of the triangular clamping grooves 4042 is bonded with rubber anti-slip pads. The controller 5 controls the electric cylinder 403 to push the pipe clamping component 404 down through the wire. According to the cross-sectional size of the main pipe, the triangular clamping grooves 4042 are used to clamp and position one end of the main pipe. The rubber anti-slip pads enhance the anti-slip performance of the triangular clamping grooves 4042 in clamping the main pipe.

[0031] In this embodiment, please refer to Figure 1 A controller 5 is installed on the outside of the limit frame 1. The controller 5 is electrically connected to the motor 1011, the electric telescopic rod 203, the motor 2043, the electric cylinder 303 and the electric cylinder 403 through wires to control the above equipment.

[0032] In addition, it should be noted that the motor, electric telescopic rod 203, electric cylinder and controller 5 are all existing technologies, and their internal working principles and operation procedures will not be described in detail here.

[0033] The working process of this utility model is as follows: First, the main pipe is placed between two sets of main pipe clamping frames 4. The controller 5 controls the electric cylinder 403 via a wire to push the clamping component 404 to slide down through the guide sliding hole 4041 and the limiting sliding rod 401. According to the cross-sectional dimensions of the main pipe, the triangular clamping groove 4042 is used to clamp and position one end of the main pipe. The branch pipe is placed on top of the branch pipe clamping frame 3. The controller 5 controls the electric cylinder 303 via a wire to push the clamping component 304 to descend. According to the cross-sectional dimensions of the branch pipe, the triangular clamping groove 305 is used to clamp and position the branch pipe. The rubber anti-slip pad enhances the anti-slip performance of the triangular clamping groove 305 on the branch pipe, improving the clamping and welding of the main pipe and the branch pipe. To ensure stability, motor 1011 drives adjusting screw 101 to rotate, causing sliding frame 201 to be threadedly connected to adjusting screw 101 through threaded adjusting hole 2011. This causes the branch pipe held at the top of branch pipe clamping frame 3 to connect with the main pipe held at the top of main pipe clamping frame 4. Motor 2043 drives adjusting screw 2042 to rotate, causing branch pipe clamping frame 3 to be threadedly connected to adjusting screw 2042 through threaded adjusting hole 301. This causes the branch pipe to move left and right on adjusting table 204 according to the welding position. Electric telescopic rod 203 pushes the branch pipe at the top of branch pipe clamping frame 3 through adjusting table 204 to adjust the height according to the welding position, improving the convenience of welding adjustment between branch pipe and main pipe.

[0034] The entire operation process is simple and convenient. Compared with existing branch pipe welding equipment, this utility model can improve the stability of branch pipe and main pipe welding and the convenience of adjusting the welding position of branch pipe through design, thus enhancing the overall practicality.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
