Technical Field
[0001] This utility model relates to the field of welding technology, specifically a welding butt welding device for chemical equipment production. Background Technology
[0002] A pressure vessel is a device used to store or process substances by compressing media such as gas, liquid, or steam. Pressure vessels are generally made by welding together multiple vessel sections.
[0003] In the prior art, patent announcement number CN222626567U discloses a pressure vessel welding and docking device, including a base plate, movable connecting shafts, a bottom support structure, an adjustment and fixing structure, and a rotating structure; the inner ends of the two movable connecting shafts are fixedly connected to the adjustment and fixing structure, a right support plate is provided on the upper right side of the base plate, and a rotating structure is provided at the upper recess of the right support plate; two bottom support structures are slidably connected to the left end of the right support plate and the middle of the upper end of the base plate; the bottom support structure includes a slide, a telescopic rod, a supporting arc plate, and a round shaft; the telescopic rod is provided on the bottom support structure, the lower end of the telescopic rod is fixedly connected to the slide, the upper end of the telescopic rod is fixedly connected to the round shaft, and the left and right ends of the round shaft are movably connected to the supporting arc plate.
[0004] The aforementioned device utilizes the extension and retraction of an electric actuator to push the vessel pipe sections, achieving the docking of pressure pipelines. However, in actual industrial applications, we have found that some pressure vessels have relatively thin pipe walls, and these vessels are not equipped with sufficient limiting measures during docking. This makes it difficult to achieve precise alignment of the pipe ends during the docking process. The misalignment during docking directly affects the welding quality, potentially impacting the safety and reliability of the entire vessel. Utility Model Content
[0005] The purpose of this invention is to provide a welding and butt welding device for chemical equipment production, so as to solve the problem that it is difficult to accurately butt together thin container pipe sections in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding and butt welding device for chemical equipment production, comprising a container pipe section, a movable base at one end of the container pipe section, a support bracket fixedly installed on the movable base, a drive mechanism fixedly installed on the support bracket, the drive mechanism comprising a mechanism housing fixedly installed on the support bracket, a helical gear disk rotatably installed inside the mechanism housing, a helical gear rotatably installed around the helical gear disk, a drive shaft fixedly connected to the helical gear, and a limit mechanism fixedly installed on the mechanism housing.
[0007] Preferably, the drive mechanism further includes a motor fixedly installed on one side of the mechanism housing and a cylinder fixedly installed on the other side of the mechanism housing. The output end of the cylinder is fixedly installed with a mating pressure plate, and the output end of the motor is fixedly installed at the middle position of the helical gear plate.
[0008] Preferably, the housing of the mechanism is provided with a bearing, and the drive shaft is rotatably mounted in the housing of the mechanism through the bearing.
[0009] Preferably, the helical gear disk is mounted inside the mechanism housing by a motor, and the helical gear disk meshes with the helical gear. The mating pressure plate is mounted in front of the mechanism housing by a cylinder.
[0010] Preferably, the limiting mechanism includes a mounting arm fixedly mounted on the mechanism housing, a drive screw rotatably mounted on the mounting arm, a screw slider threadedly mounted on the drive screw, an upper clamping roller rotatably mounted on the screw slider, and the lower end of the drive screw fixedly mounted on a drive shaft. A sliding sleeve is slidably mounted on the mounting arm, locking bolts are threadedly mounted at both ends of the sliding sleeve, and a lower clamping roller is rotatably mounted on the sliding sleeve.
[0011] Preferably, the mounting arm has a sliding groove, and the sliding sleeve is slidably mounted on the mounting arm through the sliding groove.
[0012] Preferably, the lower clamping roller is slidably mounted on one side of the mounting arm via a sliding sleeve, the upper clamping roller is slidably mounted on one side of the mounting arm via a lead screw and slider, and the sliding sleeve is secured to the mounting arm by a locking bolt.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In this application, after the motor starts, it drives the drive shaft to rotate. Subsequently, the rotation of the drive shaft causes the drive screw to rotate, which in turn drives the screw slider to move downward. The downward movement of the slider causes the upper clamping roller to move downward, so that the upper and lower clamping rollers clamp the two container pipe sections to be welded. During this process, the upper and lower clamping rollers remain parallel to ensure precise alignment of the two container pipe sections.
[0015] 2. In this application, after loosening the locking bolts, the sliding sleeve can slide freely on the mounting arm, thereby adjusting the position of the lower clamping rollers. This operation ensures that the distance between the two lower clamping rollers in relative positions is equal to the diameter of the container pipe segment. Subsequently, the container pipe segment to be welded is placed on the lower clamping rollers. After the container pipe segment is placed on the lower clamping rollers, the initial docking of the container pipe segments is completed by controlling the movement of the moving base. When the two container pipe segments are precisely aligned, the cylinder is activated. After the cylinder is activated, it drives the docking pressure plate to move forward. The forward movement of the docking pressure plate applies pressure to the container pipe segments to be welded, causing the two precisely aligned container pipe segments to fit tightly together, thereby facilitating the welding operation.

[0021] 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.
[0022] like Figure 1 and Figure 2As shown, this utility model provides a technical solution for a welding and butt welding device for chemical equipment production, including a container pipe section 3, a movable base 1 at one end of the container pipe section 3, a support bracket 2 fixedly installed on the movable base 1, a drive mechanism 4 fixedly installed on the support bracket 2, and a limiting mechanism 5 fixedly installed on the mechanism housing 401. Through the cooperation of the drive mechanism 4 and the limiting mechanism 5, two container pipe sections 3 can be precisely aligned and tightly butt welded together, facilitating welding operations.
[0023] like Figure 2 and Figure 3 As shown, the drive mechanism 4 includes a mechanism housing 401 fixedly mounted on the support bracket 2. A helical gear disk 403 is rotatably mounted inside the mechanism housing 401. A helical gear 405 is rotatably mounted around the helical gear disk 403. A drive shaft 406 is fixedly connected to the helical gear 405. The drive mechanism 4 also includes a motor 402 fixedly mounted on one side of the mechanism housing 401 and a cylinder 404 fixedly mounted on the other side of the mechanism housing 401. A mating pressure plate 407 is fixedly mounted at the output end of the cylinder 404, and the output end of the motor 402 is fixedly mounted at the middle position of the helical gear disk 403. A bearing is provided on the mechanism housing 401, and the drive shaft 406 is rotatably mounted inside the mechanism housing 401 through the bearing.
[0024] Specifically, when motor 402 is started, it begins to rotate, thereby driving the drive shaft 406 connected to it. As drive shaft 406 rotates, it transmits power to drive screw 505, causing it to rotate as well. The rotation of drive screw 505 causes screw slider 506 to move downwards along the screw. This downward movement of screw slider 506 causes upper clamping roller 504 to also move downwards. The downward movement of upper clamping roller 504 works in conjunction with lower clamping roller 503 to clamp the two container pipe sections 3 to be welded together. During this process, upper clamping roller 504 and lower clamping roller 503 remain parallel, ensuring precise alignment of the two container pipe sections 3 and providing the necessary stability and accuracy for the welding process.
[0025] like Figure 2 and Figure 4 As shown, the limiting mechanism 5 includes a mounting arm 501 fixedly mounted on the mechanism housing 401. A drive screw 505 is rotatably mounted on the mounting arm 501. A screw slider 506 is threaded onto the drive screw 505. An upper clamping roller 504 is rotatably mounted on the screw slider 506. The lower end of the drive screw 505 is fixedly mounted on the drive shaft 406. A sliding sleeve 502 is slidably mounted on the mounting arm 501. Locking bolts 507 are threaded onto both ends of the sliding sleeve 502. A lower clamping roller 503 is rotatably mounted on the sliding sleeve 502. A sliding groove is provided on the mounting arm 501, and the sliding sleeve 502 is slidably mounted on the mounting arm 501 through the sliding groove.
[0026] Specifically, after loosening the locking bolt 507, the sliding sleeve 502 can slide freely on the mounting arm 501, thereby adjusting the position of the lower clamping roller 503. This adjustment ensures that the distance between the relatively positioned lower clamping rollers 503 is equal to the diameter of the container tube segment 3. Then, the container tube segment 3 to be welded is placed on the lower clamping roller 503. After placing the container tube segment 3 on the lower clamping roller 503, the initial docking of the container tube segment 3 is completed by controlling the movement of the movable base 1. When the two container tube segments 3 are precisely aligned, the cylinder 404 is activated. After the cylinder 404 is activated, it drives the docking pressure plate 407 to move forward. The forward movement of the docking pressure plate 407 applies pressure to the container tube segment 3 to be welded, causing the two precisely aligned container tube segments 3 to fit tightly together, facilitating the smooth progress of the welding operation.
[0027] Working principle: First, loosen the locking bolt 507. After loosening the locking bolt 507, the sliding sleeve 502 can slide on the mounting arm 501, thereby adjusting the position of the lower clamping rollers 503 so that the distance between the two opposing lower clamping rollers 503 is equal to the diameter of the container pipe segment 3. Then, the container pipe segment 3 to be welded can be placed on the lower clamping rollers 503. After the container pipe segment 3 is placed on the lower clamping rollers 503, the moving base 1 can be controlled to move, so that the container pipe segment 3 completes the initial connection. After the container pipe segment 3 completes the initial connection, the motor 402 can be started. After starting the motor 402, it will drive the drive shaft 406 to rotate, and the drive shaft 406 will drive the drive screw 505 to rotate. After the lead screw 505 rotates, it will drive the lead screw slider 506 to move downward. After the lead screw slider 506 moves downward, it will drive the upper clamping roller 504 to move downward. Thus, the upper clamping roller 504 and the lower clamping roller 503 will clamp the two container pipe sections 3 to be welded together. The upper clamping roller 504 and the lower clamping roller 503 will remain parallel, so that the two container pipe sections 3 can be precisely aligned. After the two container pipe sections 3 are precisely aligned, the cylinder 404 can be activated. After the cylinder 404 is activated, it will drive the docking pressure plate 407 to move forward. After the docking pressure plate 407 moves forward, it will squeeze the container pipe sections 3 to be welded, so that the two precisely aligned container pipe sections 3 are tightly joined together, which facilitates the welding operation.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
