Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a welded structure for building steel structures with adjustable support angle. Background Technology

[0002] This type of welded steel structure with adjustable support angle is mainly used in building engineering to meet requirements for load-bearing capacity, stability, precise adjustment, and ease of construction. These welded steel structures are typically used in building projects that need to bear heavy loads or have specific angle requirements, such as bridges, towers, and high-rise buildings. The background technology will be detailed below. Steel structures are widely used in modern architecture, especially in the construction of high-rise buildings, large-span buildings, and some special structures. Steel structures have advantages such as high strength, durability, and good seismic performance, and can provide stable support under various complex load conditions.

[0003] Patent publication number CN221833607U discloses a welding and joining structure for steel structure columns, including a mobile trolley. The mobile trolley has support seats at both the front and rear ends of its upper surface. The top opening of each support seat is arc-shaped, and a positioning frame is connected to the top of the support seat. A clamping component is provided in the middle of the positioning frame to clamp the steel structure column. Support rods are symmetrically arranged on both sides of the mobile trolley, and these support rods can move up and down along the trolley. Drive screws are connected to both sides of the mobile trolley, with their bottom ends passing through the mobile trolley and rotatably connected to the support rods. The support seats on the mobile trolley stably support the steel structure column, facilitating the joining of the steel structure columns. Simultaneously, the mobile trolley assists in the movement of the steel structure column, allowing two steel structure columns to be welded to be stably joined together, thus facilitating stable welding processing of the steel structure columns.

[0004] However, the current welded joint structure of steel columns has the following problems: when workers are welding the steel structure, the vertical clamping progress of the clamping components is different, which causes the clamping angle to deviate, resulting in the instability of the structure after welding. Therefore, we propose a welded steel structure with adjustable support angle. Utility Model Content

[0005] The purpose of this utility model is to provide a welded steel structure with an adjustable support angle, which can solve the problem in related technologies where the clamping angle deviates due to different vertical clamping progress of the clamping components during steel structure welding, resulting in unstable structure after welding.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An adjustable-angle welded steel structure for buildings includes a main platform. An accessory welding clamping assembly is mounted on the top of the main platform. A universal adjustment device is also mounted on the top of the main platform. The universal adjustment device includes a support plate. A limiting ring is fixedly connected to the top of the support plate. An adjusting ring is rotatably connected to the inner wall of the limiting ring. A bidirectional threaded rod is rotatably connected to the inner wall of the adjusting ring. A threaded profile plate is threaded onto the threaded surface of the bidirectional threaded rod. A sliding rod is slidably connected to the side of the threaded profile plate away from the bidirectional threaded rod. The top of the sliding rod is fixedly connected to the inner wall of the adjusting ring. A limit assembly is mounted on the top of the main platform.

[0008] The limiting component includes a limiting rod, the bottom of which is fixedly connected to the top of the main body platform. Multiple position holes are provided on the circumferential surface of the adjusting ring. Limiting holes are provided on the side of the limiting rod, and a fixing pin is inserted into the inner wall of the limiting hole.

[0009] The accessory welding assembly includes a sliding rail, a rail slider is fixedly and slidably connected to the inner wall of the sliding rail, a base plate is fixedly connected to the top of the rail slider, a clamping motor is fixedly connected to the side of the base plate, and a bidirectional threaded rod is fixedly connected to the output shaft of the clamping motor. Two clamping clamps are threadedly connected to the circumferential surface of the bidirectional threaded rod.

[0010] The inner diameter of the position hole is equal to the inner diameter of the limiting hole, and the inner wall of the position hole is located on the movement trajectory of the fixed pin.

[0011] A refresh device is provided on the side of the adjusting ring. The refresh device includes a friction plate, the side of which is fixedly connected to the side of the adjusting ring. Two hanging plates are fixedly connected to the bottom of the threaded irregular plate. Two rotating rods are fixedly connected to the sides of the two hanging plates. A clamping track is connected between the two rotating rods. A friction wheel is fixedly connected to the side of one of the rotating rods. A pad support rod is fixedly connected to the side of the threaded irregular plate. A pad is fixedly connected to the side of the pad support rod. A scraper is fixedly connected to the bottom of the threaded irregular plate.

[0012] The bottom of the scraper contacts the outer wall of the clamping track, the top and bottom of the pad contact the inner wall of the clamping track, and the outer wall of the friction wheel contacts the side of the friction plate near the friction wheel.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model, through the setting of a universal adjustment device, enables the support plate, limiting ring, adjusting ring, bidirectional threaded rod II, threaded profile plate, sliding rod, limiting rod, position hole, limiting hole, fixing pin, and refreshing device to cooperate. The rotation of the adjusting ring drives the threaded profile plate on the bidirectional threaded rod II to rotate. The rotation of the threaded profile plate drives the two clamping tracks to adjust the position of the welding workpiece. After the position adjustment of the welding workpiece is completed, the fixing pin is inserted into the position hole to fix the position of the adjusting ring. This avoids the deviation of the clamping angle caused by the different vertical clamping progress of the clamping components during the welding work, which would lead to the instability of the welded structure.

[0015] This invention, through the setting of a refresh device, enables the friction plate, hanging plate, rotating rod, clamping track, friction wheel, pad support rod, pad, and scraper to cooperate. The rotation of the clamping track allows the scraper to scrape off the surface of the clamping track, preventing welding particles from adhering to the track clamping surface due to repeated clamping when clamping welded workpieces. This also prevents the clamping angle from deviating due to welding particles when clamping the lower workpiece. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-6 As shown, an adjustable support angle welded steel structure includes a main platform 1. An accessory welding clamping assembly is provided on the top of the main platform 1. A universal adjustment device 8 is also provided on the top of the main platform 1. The universal adjustment device 8 includes a support plate 81. A limiting ring 82 is fixedly connected to the top of the support plate 81. An adjusting ring 83 is rotatably connected to the inner wall of the limiting ring 82. A bidirectional threaded rod 84 is rotatably connected to the inner wall of the adjusting ring 83. A threaded profile plate 85 is threadedly connected to the threaded surface of the bidirectional threaded rod 84. A sliding rod 86 is slidably connected to the side of the threaded profile plate 85 away from the bidirectional threaded rod 84. The top of the sliding rod 86 is fixedly connected to the inner wall of the adjusting ring 83. A limit assembly is provided on the top of the main platform 1.

[0026] The limiting assembly includes a limiting rod 87, the bottom of which is fixedly connected to the top of the main body platform 1. Multiple position holes 88 are provided on the circumferential surface of the adjusting ring 83. A limiting hole 89 is provided on the side of the limiting rod 87. A fixing pin 810 is inserted into the inner wall of the limiting hole 89.

[0027] The accessory welding assembly includes a sliding rail 2, a rail slider 3 is fixedly and slidably connected to the inner wall of the sliding rail 2, a base plate 4 is fixedly connected to the top of the rail slider 3, a clamping motor 5 is fixedly connected to the side of the base plate 4, a bidirectional threaded rod 6 is fixedly connected to the output shaft of the clamping motor 5, and two clamping clamps 7 are threadedly connected to the circumferential surface of the bidirectional threaded rod 6.

[0028] The inner diameter of the position hole 88 is equal to the inner diameter of the limiting hole 89, and the inner wall of the position hole 88 is located on the movement trajectory of the fixed pin 810.

[0029] Based on the above structure, the workpiece is placed inside the adjusting ring 83. The operator manually rotates the double-threaded rod 84. The rotation of the double-threaded rod 84 causes the threaded profile plate 85 to move in opposite directions along the threaded surface of the double-threaded rod 84 under the constraint of the sliding rod 86. The opposing threaded movement of the two threaded profile plates 85 causes the hanging plate 92 to move towards the center of the workpiece. The movement of the hanging plate 92 towards the center of the workpiece causes the rotating rod 93 to move towards the center of the workpiece. The movement of the rotating rod 93 towards the center of the workpiece causes the clamping track 94 to clamp the workpiece. The clamping mechanism fixes the lateral position of the welding workpiece. The operator manually rotates the adjusting ring 83, which in turn rotates the threaded profile plate 85 on the double-threaded rod 84. The rotation of the threaded profile plate 85 causes the welding workpiece clamped by the two clamping tracks 94 to adjust its position. After the position of the welding workpiece is adjusted, the fixing pin 810 is inserted into the position hole 88 to fix the position of the adjusting ring 83. This prevents the operator from causing deviations in the clamping angle due to different vertical clamping progress of the clamping components during welding, which could lead to instability in the welded structure.

[0030] like Figure 1-6 As shown, a refresh device 9 is provided on the side of the adjusting ring 83. The refresh device 9 includes a friction plate 91. The side of the friction plate 91 is fixedly connected to the side of the adjusting ring 83. Two hanging plates 92 are fixedly connected to the bottom of the threaded special plate 85. Two rotating rods 93 are fixedly connected to the sides of the two hanging plates 92. A clamping track 94 is connected between the two rotating rods 93. A friction wheel 95 is fixedly connected to the side of one rotating rod 93. A pad support rod 96 is fixedly connected to the side of the threaded special plate 85. A pad 97 is fixedly connected to the side of the pad support rod 96. A scraper 98 is fixedly connected to the bottom of the threaded special plate 85.

[0031] The bottom of scraper 98 contacts the outer wall of clamping track 94, the top and bottom of pad 97 contact the inner wall of clamping track 94, and the outer wall of friction wheel 95 contacts the side of friction plate 91 near friction wheel 95.

[0032] According to the above structure, when the two threaded special plates 85 slide in opposite directions, the friction wheel 95 contacts the friction plate 91, so the friction wheel 95 rotates under the friction force of the friction plate 91. The rotation of the friction wheel 95 drives the rotating rod 93 to rotate, and the rotation of the rotating rod 93 drives the clamping track 94 to rotate. The rotation of the clamping track 94 allows the scraper 98 to scrape the surface of the clamping track 94, so as to avoid the welding particles adhering to the track clamping surface due to repeated clamping when clamping the welded workpiece. When clamping the lower workpiece, the clamping angle will be deviated due to the welding particles.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
