Description

Technical Field

[0001] This utility model belongs to the field of straight seam welded pipe production technology, specifically, it relates to a weld seam guide roller for a straight seam welded pipe production line. Background Technology

[0002] In the production process of straight seam welded pipes, weld seam guidance is one of the key steps to ensure the quality of welded pipes. With the continuous expansion of the application fields of straight seam welded pipes, such as in the construction, machinery manufacturing, and petrochemical industries, the demand for straight seam welded pipes of different specifications is becoming increasingly diversified. This requires weld seam guiding devices to be able to adapt to the production of welded pipes of various specifications.

[0003] As a core component of the weld seam guiding device, the adaptability of the weld seam guide roller is crucial. In the prior art, patent application number CN202210744721.8, entitled "A Weld Seam Guide Roller for a Straight Seam Welded Pipe Production Line", discloses a weld seam guide roller for a straight seam welded pipe production line, including a base plate, a mounting base and a guide roller. A first servo motor is fixedly connected to the base plate, and a drive shaft is fixedly connected to the output end of the first servo motor. A turntable is fixedly connected to the end of the drive shaft away from the base plate. An auxiliary support device is provided between the base plate and the turntable. Multiple pick-and-place devices are symmetrically fixedly connected to the turntable.

[0004] While the aforementioned patent allows for the replacement of guide rollers of different sizes and models as needed for straight seam welded pipe processing, eliminating the need for a separate processing line for each guide roller size and model compared to traditional straight seam welded pipe processing, thus saving significant costs and production capacity, as well as space, the replacement of guide rollers requires repeated disassembly and assembly operations. This process not only consumes a lot of time and reduces production efficiency, but also frequently disassembling and assembling can easily lead to component damage, increasing equipment maintenance costs and downtime, and affecting the continuity and stability of the production line. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a weld seam guide roller for a straight seam welded pipe production line that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a weld seam guide roller for a straight seam welded pipe production line, including a bracket, and further including: a mounting frame disposed on the bracket; a rotating shaft rotatably connected to the mounting frame; a polygonal column fixedly connected to the rotating shaft; a mounting base mounted on multiple surfaces of the polygonal column via connecting columns; multiple guide rollers of different specifications rotatably connected to the mounting base respectively; a driving mechanism for driving the mounting frame to move, mounted on the bracket; a toothed plate fixedly mounted on the bracket via a support rod; one end of the rotating shaft near the toothed plate passes through the mounting frame and is equipped with a gear that cooperates with the toothed plate via a ratchet; and a locking assembly for locking the rotating shaft, mounted on the bracket.

[0007] Furthermore, the driving mechanism includes a slider, a drive shaft, and a motor. The bracket is located above the mounting frame and has a through slot. The slider is slidably connected in the through slot. The drive shaft is rotatably connected to the bracket near the slider. The slider is threadedly connected to the drive shaft. The motor is fixedly connected to one side of the bracket, and its output end is fixedly connected to the end adjacent to the drive shaft. The slider and the mounting frame are connected by a connecting rod.

[0008] To facilitate flexible control of the guide roller height according to requirements, so as to be applicable to straight seam steel pipes of different sizes, the connecting rod is further described as an electric telescopic rod.

[0009] Furthermore, the locking assembly includes a locking block and a locking rod. The end of the rotating shaft away from the ratchet passes through the mounting frame and is fixedly connected to the locking block. The locking block has a plurality of locking holes equidistantly spaced around its circumference for use with the locking rod. The number of locking holes is the same as the number of guide rollers. The locking rod is fixedly connected to the bracket.

[0010] To facilitate flexible disassembly and replacement of the guide roller and related components, a threaded column is fixedly connected to the end of the connecting column away from the mounting base, and a threaded hole is provided on the polygonal column to cooperate with the threaded column.

[0011] To improve utilization and reduce equipment operating costs, two mounting frames are symmetrically arranged.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the coordinated use of components such as mounting frame, rotating shaft, polygonal column, connecting column, mounting base, gear, ratchet, toothed plate, drive mechanism and locking assembly, compared with the prior art which requires the guide roller to be disassembled and replaced repeatedly, can quickly rotate the guide roller to the bottom for use by controlling the polygonal column to rotate, which greatly improves the efficiency of replacing the guide roller. This quick replacement method not only saves time, but also reduces the risk of damage to parts that may be caused by frequent disassembly and assembly, and improves the overall operational stability and reliability of the equipment, thereby improving the production efficiency and product quality of the straight seam welded pipe production line.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] Example 1:

[0022] Reference Figures 1-4A weld seam guide roller for a straight seam welded pipe production line includes a bracket 1, and further includes: a mounting frame 3 disposed on the bracket 1; a rotating shaft 301 rotatably connected to the mounting frame 3; a polygonal column 302 fixedly connected to the rotating shaft 301; a mounting base 304 mounted on multiple surfaces of the polygonal column 302 via connecting columns 303; multiple guide roller bodies 305 of different specifications rotatably connected to the mounting base 304; a drive mechanism for moving the mounting frame 3, mounted on the bracket 1; a toothed plate 4 fixedly mounted on the bracket 1 via a support rod; one end of the rotating shaft 301 near the toothed plate 4 passes through the mounting frame 3, and a gear 309 cooperating with the toothed plate 4 is mounted on it via a ratchet 308; and a locking assembly for locking the rotating shaft 301, mounted on the bracket 1.

[0023] The driving mechanism includes a slider 102, a drive shaft 2, and a motor 201. The bracket 1 is located above the mounting frame 3 and has a through groove 101. The slider 102 is slidably connected in the through groove 101. The drive shaft 2 is rotatably connected to the bracket 1 near the slider 102. The slider 102 is threadedly connected to the drive shaft 2. The motor 201 is fixedly connected to one side of the bracket 1, and its output end is fixedly connected to the end adjacent to the drive shaft 2. The slider 102 and the mounting frame 3 are connected by a connecting rod 202.

[0024] The locking assembly includes a locking block 306 and a locking rod 3010. The end of the rotating shaft 301 away from the ratchet 308 passes through the mounting frame 3 and is fixedly connected to the locking block 306. The locking block 306 has a plurality of locking holes 307 equidistantly arranged in a circle to cooperate with the locking rod 3010. The number of locking holes 307 is the same as the number of guide rollers 305. The locking rod 3010 is fixedly connected to the bracket 1.

[0025] Before the straight seam welded pipe production line starts operation, according to the expected specifications of the straight seam steel pipes to be produced, multiple guide rollers 305 of different specifications are installed on the mounting base 304 respectively. The mounting base 304 is fixed to multiple surfaces of the polygonal column 302 through the connecting column 303. The polygonal column 302 is fixedly connected to the rotating shaft 301. The rotating shaft 301 is rotatably connected to the mounting frame 3. The mounting frame 3 is set on the slider 102 through the connecting rod 202.

[0026] When the straight seam welded pipe production line is in operation and the guide roller 305 needs to be replaced due to changes in the specifications of the produced straight seam steel pipes, the motor 201 is started. The motor 201 drives the drive shaft 2 to rotate. The drive shaft 2 drives the slider 102 to move through the thread. The slider 102 drives the mounting frame 3 to move through the connecting rod 202. The mounting frame 3 drives the rotating shaft 301 to move. When the gear 309 on the rotating shaft 301 meshes with the toothed plate 4, the rotating shaft 301 will rotate under the action of the gear 309 and the toothed plate 4. The rotating shaft 301 will then drive multiple guide rollers 305 of different specifications to rotate through the polygonal column 302, the connecting column 303, and the mounting base 304. When the required guide roller 305 is used... After rotating to the bottom position, the drive shaft 2 can be rotated by the motor 201, which will then actuate the mounting frame 3 to move back. Since the gear 309 and the rotating shaft 301 are connected by a ratchet 308, the gear 309 will idle during the return process under the action of the ratchet 308, so that the rotating shaft 301 will no longer rotate. This allows the required guide roller 305 to be stably positioned at the bottom. When the mounting frame 3 returns to the initial position, the locking rod 3010 will be inserted into the locking hole 307 of the locking block 306, thereby locking and limiting the rotating shaft 301 to ensure that the required guide roller 305 can be stably positioned at the bottom, and then it can be put into use.

[0027] Compared with the existing technology that requires repeated disassembly and reassembly of the guide rollers for replacement, this application can quickly rotate the required guide roller body 305 to the bottom for use by rotating the polygonal column 302, which greatly improves the efficiency of replacing the guide roller body 305. This quick replacement method not only saves time, but also reduces the risk of component damage caused by frequent disassembly and reassembly, and improves the overall operational stability and reliability of the equipment, thereby improving the production efficiency and product quality of the straight seam welded pipe production line.

[0028] Example 2:

[0029] Reference Figures 1-4 A weld seam guide roller for a straight seam welded pipe production line is basically the same as that in Example 1, but with a further improvement: the connecting rod 202 is an electric telescopic rod, which can flexibly control the height of the guide roller body 305 according to the needs, so as to be suitable for straight seam steel pipes of different sizes, effectively improving the applicability of the guide roller.

[0030] Example 3:

[0031] Reference Figures 1-4A weld seam guide roller for a straight seam welded pipe production line is basically the same as in Embodiment 2, but with a further improvement: a threaded column is fixedly connected to the end of the connecting column 303 away from the mounting base 304, and a threaded hole is opened on the polygonal column 302 to cooperate with the threaded column. By screwing the threaded column at one end of the connecting column 303 into the corresponding threaded hole on the polygonal column 302, the connection between the mounting base 304 and the polygonal column 302 can be quickly completed; during disassembly, it can be easily separated by rotating in the opposite direction, which facilitates maintenance and replacement of the mounting base 304 and the guide roller body 305, improving the convenience and efficiency of equipment maintenance.

[0032] There are two symmetrically arranged mounting frames 3, such as Figure 1 , Figure 2 As shown, by setting two mounting frames 3, two sets of guide rollers can be set on a bracket 1, so that the two sets of guide rollers can share a toothed plate 4 and welding equipment, which greatly reduces the cost of use and has high practicality.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
