Description

Technical Field

[0001] This utility model relates to the field of steel structure engineering technology, specifically to a tooling for butt welding of H-beams in steel structures. Background Technology

[0002] In the construction practice of steel structure engineering, it is often encountered that the length of the original H-beams cannot meet the design size requirements. In this case, welding is required to butt-joint the two sections of H-beams. Currently, the commonly used butt joint connection methods in the industry mainly include Z-groove joints, flat straight-face butt joints, and embedded concave-convex joints, among other technical solutions. Different joint forms are suitable for different stress conditions and construction conditions.

[0003] After the components are joined, the technical specifications require full penetration welding of all connection nodes, specifically covering key areas such as butt welds between flanges, T-welds between flanges and webs, and center butt welds between webs. However, in actual welding operations, due to the generally large cross-sectional dimensions and self-weight of H-beams, traditional hoisting equipment struggles to achieve high-precision spatial attitude adjustment, leading to problems such as axial deviation and angle tilting during the joining process. Furthermore, the rigid constraints created by the component's self-weight often prevent the welding torch from reaching the effective welding position at some concealed weld locations, thus affecting welding quality and structural safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for butt welding H-beams in steel structures, which can quickly butt two H-beams together and adjust the angle of the two H-beams during the welding process.

[0005] This utility model provides the following technical solution: a steel structure H-beam butt joint fixture, including a base plate, on which several support columns are fixedly connected, and a rotating shaft is fixedly connected to the upper end of each support column. Both ends of the rotating shaft are rotatably connected to rotating blocks. An L-shaped placement platform is fixedly connected to the rotating blocks. Several adjustment mechanisms and adjustment mechanisms are respectively installed on both sides of the support columns.

[0006] Furthermore, the L-shaped placement platform includes an L-shaped plate fixedly connected to the rotating block, and a working area is provided on the L-shaped plate.

[0007] Furthermore, each of the two vertical plates of the L-shaped plate has equally spaced grooves one and two, and the inner walls of groove one and groove two are respectively rotatably connected to roller one and roller two, and roller one and roller two are arranged alternately.

[0008] Furthermore, the adjustment mechanism includes a rotating block two fixedly connected to the base plate. The rotating block two is located on the left side of the support column. A rotating shaft two is rotatably connected to the rotating block two. A hydraulic cylinder is fixedly connected to the rotating shaft two. A rotating shaft three is fixedly connected to the output end of the hydraulic cylinder. Rotating blocks three are rotatably connected to both ends of the rotating shaft three. The rotating block three is fixedly connected to the lower surface of the L-shaped plate.

[0009] Furthermore, the structure of the second adjustment mechanism is the same as that of the first adjustment mechanism, and the second adjustment mechanism is located on the right side of the support column.

[0010] Furthermore, several columns are fixedly connected to both sides of the base plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This type of steel structure uses H-beam butt welding fixtures. Through the fitting design of the two vertical plates of the L-shaped placement platform with the flange plates and web plates of the H-beams, it is possible to quickly and accurately butt two sections of H-beams. The alternating roller structure on the L-shaped plate facilitates the position adjustment of the H-beams during the butt welding process, reducing the intensity of manual handling. The hydraulic cylinder adjustment mechanism on both sides of the support column can flexibly control the tilt angle of the L-shaped placement platform, thereby adjusting the tilt angle of the two H-beams to facilitate welding at the joint of the two H-beams.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 3A steel structure H-beam butt joint fixture includes a base plate 1, on which a plurality of support columns 2 are fixedly connected. Each support column 2 is fixedly connected to a rotating shaft 3 at its upper end. Both ends of the rotating shaft 3 are rotatably connected to rotating blocks 4. An L-shaped placement platform 5 is fixedly connected to the rotating blocks 4. A plurality of adjustment mechanisms 1 and adjustment mechanisms 2 are respectively installed on both sides of the support column 2.

[0019] like Figures 1 to 3 As shown, in the steel structure H-beam butt welding fixture of this utility model, when in use, the two vertical plates on the L-shaped placement platform 5 are inclined relative to the ground. Two H-beams are hoisted onto the L-shaped placement platform 5. Since the two vertical plates on the L-shaped placement platform 5 are perpendicular to each other, and the flanges and webs of the H-beams are also perpendicular, the four edges of the H-beams together form a rectangle, which can fit against the two vertical plates on the L-shaped placement platform 5. In this way, the two H-beams can be quickly connected together for welding. Furthermore, during the welding process, the tilt angle of the two vertical plates on the L-shaped placement platform 5 can be adjusted by adjusting mechanism one and adjusting mechanism two, thereby adjusting the tilt angle of the upper flange and web of the H-beams. This makes it easier for workers to weld the upper flanges between the flanges, between the flanges and the webs, and between the webs of the two H-beams.

[0020] like Figure 1 or Figure 2 As shown, the L-shaped placement platform 5 includes an L-shaped plate 501 fixedly connected to the rotating block 4, and a working area 502 is provided on the L-shaped plate 501.

[0021] Specifically, L-shaped plate 501 is used to support two H-beams, and the connection between the two H-beams is located in work area 502. This distance is basically unobstructed, making it convenient for workers to weld the connection between the two H-beams at this location.

[0022] like Figure 2 As shown, the two vertical plates of the L-shaped plate 501 are provided with equally spaced grooves 11 and 12. The inner walls of grooves 11 and 12 are respectively rotatably connected to rollers 13 and 14, and rollers 13 and 14 are arranged alternately.

[0023] Specifically, the alternating arrangement of rollers 13 and 14 is to ensure that the H-beam can simultaneously contact both rollers 13 and 14. That is, the lower surface of the upper flange of the H-beam is in contact with the surface of roller 13, and the side of the upper flange is in contact with the surface of roller 14, or the side of the upper flange is in contact with the surface of roller 13, and the lower surface of the upper flange is in contact with the surface of roller 14, without contacting the inner wall of the L-shaped plate 501. The use of rollers 13 and 14 facilitates the movement of the H-beam.

[0024] like Figure 1 As shown, the adjustment mechanism includes a rotating block 6 fixedly connected to the base plate 1. The rotating block 6 is located on the left side of the support column 2. A rotating shaft 7 is rotatably connected to the rotating block 6. A hydraulic cylinder 8 is fixedly connected to the rotating shaft 7. A rotating shaft 9 is fixedly connected to the output end of the hydraulic cylinder 8. Rotating blocks 10 are rotatably connected to both ends of the rotating shaft 9. The rotating blocks 10 are fixedly connected to the lower surface of the L-shaped plate 501.

[0025] Specifically, initially, the angle between one of the vertical plates of the L-shaped plate 501 and the ground is small, which facilitates welding between the flanges of the two H-beams. When it is necessary to adjust the angle of the two H-beams, the hydraulic cylinder 8 can be activated simultaneously to extend and retract, thereby controlling the length of the hydraulic cylinder 8. During this process, the rotating shafts 7 and 9 at both ends of the hydraulic cylinder 8 rotate on the rotating blocks 6 and 10 to adjust the angle change during the length change of the hydraulic cylinder 8. During the length change of the hydraulic cylinder 8, a pushing or pulling force is applied to the L-shaped plate 501, so that the L-shaped plate 501 rotates with the rotating shaft 3 at the upper end of the support column 2. During this process, the change of the hydraulic cylinder 8 is controlled by an independent metering valve to directly control the oil inlet / outlet of each cylinder. Combined with bus communication, precise flow distribution is achieved, and the synchronization error can be less than 0.1%, so that multiple hydraulic cylinders 8 can work synchronously.

[0026] like Figure 1 or Figure 2 As shown, the structure of the second adjustment mechanism is the same as that of the first adjustment mechanism, and the second adjustment mechanism is located on the right side of the support column 2.

[0027] Specifically, as the length of the hydraulic cylinder 8 on the first adjustment mechanism changes, the second adjustment mechanism also changes accordingly. Its process and principle are the same as those of the first adjustment mechanism. By applying pushing or pulling forces to both sides of the L-shaped plate 501 on both sides of the support column 2 through the second adjustment mechanism and the first adjustment mechanism, the angle of the L-shaped plate 501 is fixed, thereby determining the angle of the two H-beams.

[0028] like Figure 1 , Figure 2 or Figure 3 As shown, several columns 15 are fixedly connected to both sides of the base plate 1.

[0029] Specifically, when the L-shaped plate 501 is slowly rotated until one of the vertical plates on the L-shaped plate 501 is parallel to the ground, its lower surface abuts against the upper end of the column 15. Thus, when welding the connection between the two H-beams, the entire weight will be supported on the column 15, thereby enabling the hydraulic cylinder 8 to release thrust or pull.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
