Description

Technical Field

[0001] This invention relates to the field of steel structure assembly technology, and in particular to an adjustable steel structure assembly platform. Background Technology

[0002] Steel trusses are rigid structural systems composed of steel members connected by nodes. They are characterized by their lightweight, high strength, large span, and flexible design, and are widely used in industrial plants, stadiums, bridges, and other buildings. The basic components of a truss include a top chord, a bottom chord, and web members. The top chord bears compressive forces and forms the top of the truss, while the bottom chord bears tensile forces and forms the bottom. The web members, including diagonal and vertical web members, are used to transmit shear forces and connect the top and bottom chords. The nodes connecting the top chord, bottom chord, and web members are typically fixed by welding to ensure reliable force transmission.

[0003] Common truss forms include triangular trusses, trapezoidal trusses, and arched trusses. In the fabrication of equilateral triangular trusses, the individual top chords, bottom chords, and web members need to be assembled into a whole. This is typically done using a fixed assembly jig platform for support, or by manually positioning and pre-assembling the individual members one by one using clamps. Only after this positioning and assembly can subsequent welding operations proceed. However, fixed assembly jig platforms usually need to be customized according to the component dimensions, resulting in high production costs. Furthermore, fixed jigs lack flexibility and are not easily adaptable to changes in the angles of member connections, limiting assembly capabilities and affecting welding accuracy. Secondly, the numerous joints and complex angles of equilateral triangular trusses, along with the different angles between diagonal and vertical web members and their corresponding chords, make manual positioning and clamping difficult, impacting assembly and welding efficiency and quality. Thirdly, during welding, inclined web members are prone to displacement, making it difficult to completely align the joints, further affecting welding accuracy.

[0004] Therefore, in order to improve the flexibility of assembly and the efficiency and quality of assembly and welding, this invention provides an adjustable steel structure assembly platform. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an adjustable steel structure assembly platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable steel structure assembly platform includes a platform body, on which symmetrical slide rails for welding robots are provided on the left and right sides. String support members are symmetrically arranged on the front and back of the platform body, and the string support members are used to support the two ends of the string group. An assembly mechanism is provided on the platform body.

[0008] The assembly mechanism includes a drive assembly mounted on the platform body, a web member assembly assembly mounted on the drive assembly, and a chord member stabilizing assembly. The web member assembly assembly is used to clamp the diagonal web member groups and vertical web member groups in batches, and to adjust their rotation according to the angle at which the diagonal web member groups and vertical web member groups are spliced ​​with the outer walls of the corresponding chord members. The chord member stabilizing assembly is used to limit the middle part of the chord member groups in batches and to maintain stable splicing at the connection nodes between the chord member groups and the diagonal web member groups and vertical web member groups. The drive assembly is used to support the web member assembly assembly assembly and the chord member stabilizing assembly, and to drive the web member assembly assembly assembly and the chord member stabilizing assembly to rotate and adjust.

[0009] In the aforementioned adjustable steel structure assembly platform, the chord support includes three support members bolted to the top wall of the platform body. The support members consist of an electric telescopic rod and a clamp fixedly installed on the top wall of the output end of the electric telescopic rod. The clamp supports and locks the two ends of the upper and lower chords, and the height of the upper and lower chords is adjusted by the electric telescopic rod.

[0010] In the aforementioned adjustable steel structure assembly platform, a second slide rail assembly is provided in the middle of the platform body, and both the first slide rail and the second slide rail assembly are oriented front to back. The assembly mechanism includes a frame-shaped support frame, and the second slide rail assembly is connected to the support frame by an electric slider that slides back and forth.

[0011] In the aforementioned adjustable steel structure assembly platform, a circular ring is fixedly connected to the inner wall of the support frame, and a bevel gear ring is rotatably connected to the rear side wall of the circular ring. A motor is installed on the support frame, and a bevel gear that meshes with the bevel gear ring is fixedly connected to the top output end of the motor.

[0012] In the aforementioned adjustable steel structure assembly platform, the web member assembly component includes an L-shaped frame, and the inner wall of the ring member is fixedly connected with an L-shaped frame that is staggered with the chord member group along the circumferential direction. The side wall of the L-shaped frame near the center of the ring member is rotatably connected with a U-shaped frame.

[0013] In the aforementioned adjustable steel structure assembly platform, a bevel gear two is coaxially and fixedly connected to the U-shaped frame and rotatably connected to the L-shaped frame, and the bevel gear two meshes with the bevel gear ring.

[0014] In the aforementioned adjustable steel structure assembly platform, the U-shaped frame consists of a main board and two support plates. The main board of the U-shaped frame is slidably connected to a movable plate via an electric slider, and the two support plates of the U-shaped frame are rotatably connected to an X-shaped clamping component via a rotating shaft.

[0015] In the aforementioned adjustable steel structure assembly platform, the X-type clamping component is composed of two symmetrical movable hooks. The two movable hooks are used to clamp the members of the diagonal web member group and the vertical web member group. The ends of the two movable hooks near the moving plate are hinged with connecting parts, and the ends of the two connecting parts away from the corresponding X-type clamping component are hinged with the moving plate.

[0016] In the aforementioned adjustable steel structure assembly platform, the chord stabilizing component includes a support frame. The rear sidewall of the ring component is fixedly connected to a support frame corresponding to the chord assembly along the circumferential direction, and a bevel gear three that meshes with the bevel gear ring is rotatably connected to the support frame.

[0017] In the aforementioned adjustable steel structure assembly platform, a rotating rod is fixed coaxially on the support frame of the bevel gears. On the side of the support frame near the center of the ring component, two limiting components that limit the chord rod are symmetrically slidably connected with the rotating rod as the center. Both ends of the rotating rod are hinged to the two limiting components.

[0018] Compared with existing technologies, the advantages of this invention are:

[0019] 1. The assembly mechanism is used to perform splicing operations between diagonal web members, vertical web members and their corresponding chord members. The U-shaped frame is driven by a motor and can rotate to drive the X-shaped clamping parts. The rotation of the X-shaped clamping parts causes the web members being clamped to rotate, so as to adapt to different connection angles specified between the members. It can adapt to the splicing angle between diagonal web members and their corresponding chord members, and the splicing angle between vertical web members and their corresponding chord members, thus improving the flexibility of the assembly equipment.

[0020] 2. A set of diagonal web members and a set of vertical web members are spliced ​​alternately to improve splicing efficiency, thereby reducing welding preparation time and improving welding efficiency; two movable clamping hooks hold the corresponding web members, and multiple web members are clamped in batches simultaneously. The X-shaped clamping parts and the clamped web members are rotated and adjusted, and multiple web members are rotated and adjusted in batches simultaneously, eliminating the need for manual one-by-one connection and continuous support, while avoiding the use of clamps for repeated disassembly and assembly.

[0021] 3. The assembly mechanism enables mechanized rotation adjustment and alignment, while two limiting components limit the corresponding chord members. The movable clamping hooks hold the web members to prevent displacement, ensuring the stability of the splicing nodes between the chord members and web members during welding. Furthermore, by improving the accuracy of the connection of multiple splicing nodes, the quality of subsequent welding processes is improved. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 3An adjustable steel structure assembly platform includes a platform body 1. The left and right sides of the platform body 1 are symmetrically provided with slide rails for welding robots to process. The platform body 1 is symmetrically provided with chord support members 2 at the front and back. The chord support members 2 are used to support the two ends of the chord group. The platform body 1 is provided with an assembly mechanism 3.

[0036] Reference Figures 1 to 3 The chord support 2 includes three support members that are bolted to the top wall of the platform body 1. The support members consist of an electric telescopic rod and a clamp fixedly installed on the top wall of the output end of the electric telescopic rod. First, the clamp supports and locks the two ends of the upper and lower chords, and then the height of the upper and lower chords is adjusted by the electric telescopic rod.

[0037] It should be noted that in this scheme, the chord group forming the equilateral triangular truss consists of one upper chord and two lower chords, with an included angle of 60 degrees between each chord. The diagonal web members consist of three members of equal length welded obliquely between two adjacent chords, while the vertical web members consist of three members of equal length welded vertically between two adjacent chords. Two assembly mechanisms 3 are provided, which can be used to assemble and process the diagonal web members and vertical web members respectively (e.g., ...). Figure 1 and Figure 2 (As shown).

[0038] Before welding, an integration and assembly operation is performed. First, the height and position of one upper chord and two lower chords are adjusted using the electric telescopic rod of the chord support 2. Then, the ends of the upper and lower chords are locked using the clamps of the chord support 2. The assembly mechanism 3 clamps the diagonal web plate group and the vertical web plate group in batches and splices them with the corresponding chords. At the same time, the assembly mechanism 3 can restrict the middle position of the chords, increasing the stability during welding. The welding robot slides from front to back on the slide rail 1, driven by an electric slider, and performs welding. One set of diagonal web plate group and one set of vertical web plate group are spliced ​​alternately in sequence. After each set is spliced, the welding operation is performed (e.g., Figure 3 (As shown).

[0039] Reference Figure 1 and Figure 2 The assembly mechanism 3 includes a drive assembly 31 mounted on the platform body 1, a web member assembly assembly 32 mounted on the drive assembly 31, and a chord member stabilizing assembly 33. The web member assembly assembly 32 is used to clamp the diagonal web member groups and vertical web member groups in batches, and to adjust the rotation according to the angle at which the diagonal web member groups, vertical web member groups and the outer wall of the corresponding chord members are spliced. The chord member stabilizing assembly 33 is used to limit the middle part of the chord member groups in batches and to maintain the stable splicing at the connection nodes between the chord member groups and the diagonal web member groups and vertical web member groups. The drive assembly 31 is used to support the web member assembly assembly 32 and the chord member stabilizing assembly 33, and to drive the web member assembly assembly 32 and the chord member stabilizing assembly 33 to rotate and adjust.

[0040] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The platform body 1 has a second slide rail assembly in the middle. Both the first slide rail and the second slide rail assembly are oriented front to back. The assembly mechanism 3 includes a frame-shaped support frame 311. The support frame 311 is slidably connected to the second slide rail assembly via an electric slider. A ring 314 is fixedly connected to the inner wall of the support frame 311. A bevel gear ring 315 is rotatably connected to the rear side wall of the ring 314. A motor 312 is installed on the support frame 311. A bevel gear 313 that meshes with the bevel gear ring 315 is fixedly connected to the top output end of the motor 312.

[0041] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The web member assembly 32 includes an L-shaped frame 321. An L-shaped frame 321, which is staggered with the chord members, is fixedly connected to the inner wall of the ring member 314 along the circumferential direction. A U-shaped frame 323 is rotatably connected to the side wall of the L-shaped frame 321 near the center of the ring member 314. A bevel gear 322, rotatably connected to the L-shaped frame 321, is coaxially fixed to the U-shaped frame 323. The bevel gear 322 meshes with a bevel ring 315. The U-shaped frame 323 consists of a main plate and two support plates. A movable plate 324 is slidably connected to the main board via an electric slider. An X-shaped clamping member 326 is rotatably connected between the two support plates of the U-shaped frame 323 via a rotating shaft. The X-shaped clamping member 326 is composed of two symmetrical movable hooks. The two movable hooks are used to clamp the members of the diagonal web bar group and the vertical web bar group. The ends of the two movable hooks near the movable plate 324 are hinged to the connecting members 325. The ends of the two connecting members 325 away from the corresponding X-shaped clamping member 326 are hinged to the movable plate 324.

[0042] Reference Figure 1 , Figure 9 and Figure 10 The chord stabilizing assembly 33 includes a support frame 331. The rear side wall of the ring 314 is fixedly connected to a support frame 331 corresponding to the chord assembly along the circumferential direction. A bevel gear 332 that meshes with a bevel ring 315 is rotatably connected to the support frame 331. A rotating rod 333 that rotates on the support frame 331 is coaxially fixed to the bevel gear 332. Two limiting members 335 that limit the chord are symmetrically slidably connected on the side of the support frame 331 near the center of the ring 314 with the rotating rod 333 as the center. Connecting rods 334 are hinged between the two ends of the rotating rod 333 and the two limiting members 335.

[0043] When splicing the diagonal web members and the vertical web members, the initial state of the U-shaped frame 323 is that the main plate of the U-shaped frame 323 is parallel to the chord group (e.g., Figure 5 and Figure 7As shown in the initial state), the corresponding web members are manually placed in batches at the X-type clamp 326, and the X-type clamp 326 clamps the corresponding web members.

[0044] The specific operation of the X-type clamping member 326 in clamping the web member is as follows: The electric slider drives the moving plate 324 to slide into the U-shaped frame 323, causing the hinged end of the connecting member 325 to change from an initial horizontal state to an inclined state. The other end of the connecting member 325 drives the hinged end of the X-type clamping member 326 to make a corresponding displacement and deflection. The ends of the two movable hooks of the X-type clamping member 326 change from a state of being far apart to a state of being close together, and the two movable hooks clamp the corresponding web member (e.g., Figure 8 As shown in the figure, multiple web members are clamped simultaneously in batches, eliminating the need for manual connection and continuous support, while also avoiding the use of clamps for repeated disassembly and clamping.

[0045] After clamping, the top output end of motor 312 rotates, driving bevel gear 313 to rotate. Bevel gear 313 drives bevel ring 315 to rotate, which in turn drives bevel gear 322 and U-shaped frame 323 to rotate. X-shaped clamping component 326 and the clamped web member rotate and adjust. Multiple web members rotate synchronously in batches, eliminating the need for manual one-by-one connection and continuous support. This achieves mechanized rotation adjustment and alignment, improving the accuracy of multiple splicing nodes and enhancing the quality of subsequent welding processes. After rotation, the inclined web member group tilts and splices with the chord member (e.g., Figure 4 and 5 As shown), after the vertical web members are rotated, they are perpendicularly spliced ​​with the chord members (as shown). Figure 6 and Figure 7 (As shown).

[0046] When assembling the diagonal and vertical web member groups, the assembly mechanism 3 limits the middle part of the chord member group. The specific actions are as follows: While the bevel ring 315 rotates, it drives the bevel gear 332 to rotate. The bevel gear 332 drives the rotating rod 333 to rotate. The rotating rod 333 pulls one end of the hinged connecting rod 334 to move. The other end of the connecting rod 334 pulls the limiting member 335 on the support frame 331, changing it from a state of separation to a state of proximity. The two limiting members 335 limit the corresponding chord members (e.g., ...). Figure 9 As shown, the limiting position is close to the welding processing position, but will not interfere with the welding, maintaining the stability of the splicing node during welding processing, which is beneficial to improving the quality of subsequent welding processing.

[0047] It should be noted that when the assembly mechanism 3 is used to assemble the diagonal web members, the limiting member 335 has an arc shape on the side near the chord member that fits against the side wall of the chord member, which can limit the chord member from both the front and rear directions; when the assembly mechanism 3 is used to assemble the vertical web members, the lower part of the limiting member 335 is inverted triangular and presses against the chord member, limiting the chord member while preventing interference with the welding joints (such as...). Figure 10 (As shown).
