Description

Technical Field

[0001] This utility model relates to the field of engineering technology of steel structure buildings, and in particular to a device for assembling end frames. Background Technology

[0002] With the continuous development of steel structure building technology in my country, the application of steel structures in public buildings and infrastructure is becoming increasingly widespread. For example, railway stations, warehouses, and various public facilities all extensively utilize steel structures. Steel structures, with their advantages of light weight, simple construction, and good seismic performance, provide stable, safe, and economical structural support for these buildings. Currently, Modular Integrated Construction (MiC) is an innovative construction method that breaks down a building into multiple modules. All construction processes, including structure, decoration, water and electricity, and equipment pipelines, are completed in a factory, and then transported to the construction site for rapid assembly to form a complete building. Since most of the construction work is completed in the factory, only module assembly is required on-site, significantly shortening the construction cycle and improving construction efficiency. At the same time, this "building houses like cars" production method reduces on-site manpower requirements and lowers construction costs. Factory production ensures the precision and quality of building components, improving the overall performance and safety of the building. Furthermore, through standardized modules and materials, MiC construction also improves production efficiency and quality stability. The modular design makes MiC building spaces more flexible and diverse, meeting the needs of different users. This flexibility is reflected not only in architectural space, but also in architectural function and use, making it possible for architectural diversity and personalization.

[0003] In general, steel structures are widely used in construction projects due to their advantages such as high strength, light weight, fast construction speed, and flexible design. Furthermore, with technological advancements and increasing demand, their application scenarios continue to expand. However, in the production and processing of standardized modules, inaccurate positioning often leads to excessive welding errors, resulting in modules that cannot achieve standardization. This causes assembly problems during on-site installation, affecting construction progress and increasing customer costs. Utility Model Content

[0008] A further technical solution includes a bottom beam, with the frame slidably positioned above the bottom beam and capable of driving the platform to move on the bottom beam.

[0009] A further technical solution involves the platform comprising a first platform and a second platform. The first platform is fixedly disposed at one end of the frame, and the second platform is slidably disposed at the other end of the frame.

[0010] A further technical solution is that the first linear movement mechanism includes a first linear guide rail and a first slider. The first linear guide rail is fixed to the bottom beam and arranged along the extension direction of the bottom beam. The first slider is slidably connected to the first linear guide rail and connected to the frame. The second linear movement mechanism includes a second linear guide rail and a second slider. The second linear guide rail is fixed to the frame and arranged along the length direction of the frame. The second slider is slidably connected to the second linear guide rail and connected to the second platform.

Detailed Implementation

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This embodiment provides a device for assembling end frames, such as... Figure 1 , Figure 2 As shown, the system includes a frame 1 and a platform 2 mounted on the frame 1. The distance between the two frames 1 is adjustable to accommodate the length of the crossbeam 31 of the end frame 3; the distance between the two platforms 2 on the same frame 1 is adjustable to accommodate the length of the column 32 of the end frame 3. A crossbeam positioning assembly 4 and a column positioning assembly 5 are provided on the platform 2. The crossbeam positioning assembly 4 can position and clamp the crossbeam 31, and the column positioning assembly 5 can position and clamp the column 32.

[0029] In the above technical solution, the distance between the two frames 1 can be freely adjusted, allowing the device to easily handle end frames 3 of various sizes and specifications. The beam positioning assembly 4 and column positioning assembly 5 installed on the platform 2 are used to position and clamp the beam 31 and column 32, respectively. This ensures the precise positioning and stability of the end frame 3 during installation or processing, avoiding deviations or errors caused by inaccurate positioning. Precise positioning and clamping improve the processing accuracy and overall quality of the product.

[0030] It should be noted that the movement of frame 1 and platform 2 can be done manually or by means of mechanical devices. This embodiment only shows the manual movement method. In the case of manual movement, the equipment itself has a certain damping to ensure that frame 1 or platform 2 will not move arbitrarily after it is moved to the corresponding position. If necessary, a corresponding limiting structure can be set.

[0031] Specifically, in this embodiment, a bottom beam 6 is also included. The frame 1 is slidably disposed above the bottom beam 6 and can drive the platform 2 to move on the bottom beam 6. The bottom beam 6 not only provides strong support for the frame 1, but also ensures that the frame 1 maintains a high degree of stability and accuracy during sliding. This indirectly guarantees the positioning accuracy and processing quality during the machining process.

[0032] In this embodiment, platform 2 includes a first platform 21 and a second platform 22. The first platform 21 is fixedly disposed at one end of the frame 1, and the second platform 22 is slidably disposed at the other end of the frame 1.

[0033] Specifically, the bottom beam 6 and the frame 1 are connected by a first linear motion mechanism 7 to allow the frame 1 to move along the length of the bottom beam 6; the frame 1 and the second platform 22 are connected by a second linear motion mechanism 8 to allow the second platform 22 to move along the length of the frame 1. (Reference) Figure 5 and Figure 6 As shown, the first linear motion mechanism 7 includes a first linear guide rail 71 and a first slider 72. The first linear guide rail 71 is fixed to the bottom beam 6 and is arranged along the extension direction of the bottom beam 6. The first slider 72 is slidably connected to the first linear guide rail 71 and connected to the frame 1. The second linear motion mechanism 8 includes a second linear guide rail 81 and a second slider 82. The second linear guide rail 81 is fixed to the frame 1 and is arranged along the length direction of the frame 1. The second slider 82 is slidably connected to the second linear guide rail 81 and connected to the second platform 22.

[0034] Both the first linear moving mechanism 7 and the second linear moving mechanism 8 employ a combination of linear guide rails and sliders, a structure that offers high stability and precision. During movement, the slider slides smoothly along the guide rails, ensuring the stability and positioning accuracy of the frame 1 and the second platform 22. The linear guide rails and sliders have a simple structure, are easy to maintain, extend the service life of the equipment, and reduce maintenance costs.

[0035] Specifically, in this embodiment, the first linear motion mechanism 7 is also connected to a drive device 9, as shown in the reference. Figure 6 As shown, the driving device 9 includes a driving cylinder 91 and a connecting rod 92. The driving cylinder 91 is fixedly connected to the bottom beam 6. One end of the connecting rod 92 is connected to the driving cylinder 91, and the other end is hinged to the first slider 72.

[0036] It should be noted that the main function of the drive device 9 is to push the two frames 1 apart. After the crossbeam 31 and column 32 of the end frame 3 are assembled and welded, the two frames 1 can be quickly opened to facilitate the insertion and assembly of the next frame 1. This saves manpower.

[0037] For details, please refer to Figure 3 and Figure 4As shown, in this embodiment, the beam positioning assembly 4 includes a first clamping cylinder 41 and a positioning seat 42. The output end of the first clamping cylinder 41 is connected to a pressure head 43, which is used to press the beam 31 onto the positioning seat 42. The column positioning assembly 5 includes a second clamping cylinder 51 and a center positioning end 52. The second clamping cylinder 51 drives the center positioning end 52, which is used to clamp the column 32 from both ends.

[0038] Here, firstly, the crossbeam positioning assembly 4, through the cooperation of the first clamping cylinder 41 and the positioning seat 42, achieves precise pressing and positioning of the crossbeam 31. The output end of the first clamping cylinder 41 is connected to the pressure head 43. When the cylinder works, the pressure head 43 presses the crossbeam 31 tightly onto the positioning seat 42, thereby ensuring the stability and accuracy of the crossbeam 31 during processing or assembly. This not only improves positioning accuracy but also effectively prevents the crossbeam 31 from moving or shifting during processing. Secondly, the column positioning assembly 5, through the combination of the second clamping cylinder 51 and the center positioning end 52, achieves clamping at both ends of the column 32. The second clamping cylinder 51 drives the center positioning end 52. When the cylinder works, the center positioning end 52 clamps simultaneously from both ends of the column 32, ensuring the verticality and stability of the column 32. It should be noted that the two ends of the column 32 of the end frame 3 have grooves or bosses that mate with the aforementioned central positioning end 52, allowing for a good fit with the structure of the central positioning end 52 and achieving precise positioning. This further enhances the vibration resistance and deformation resistance of the column 32 during processing, further ensuring processing quality. Furthermore, this positioning and clamping assembly design offers high flexibility and adaptability. Both the crossbeam 31 and the column 32 can be adapted to workpieces of different sizes and specifications by adjusting the working pressure and clamping force of the cylinder. Simultaneously, due to the use of cylinder drive, the entire positioning and clamping process can be automated, improving production efficiency and processing accuracy.

[0039] Specifically, in this embodiment, reference is made to... Figure 1 As shown, it also includes a conveyor mechanism 10, which is vertically and vertically disposed between the two frames 1 for transporting the assembled end frames 3 to the next workstation. When the conveyor mechanism 10 is in the lowered position, it makes way for the assembly of the end frames 3; when the conveyor mechanism 10 is in the raised position, it transports the end frames 3. Specifically, the conveyor mechanism 10 is connected to the frame 1 via a lifting mechanism 11, which includes a lifting cylinder fixed to the frame 1. The lifting cylinder is fixed to the inner side of the frame 1 via a mounting base.

[0040] Through the ingenious design of the lifting cylinder 111 and the mounting base 112, the conveyor mechanism 10 can be lowered to a low position when not needed, providing ample space for the assembly of the end frame 3, allowing the assembly work to proceed smoothly without interference from the conveyor mechanism 10. This allows workers to complete assembly tasks more efficiently. After assembly, the conveyor mechanism 10 can quickly rise to the raised position, transporting the assembled end frame 3 to the next workstation, improving work efficiency and making the layout of the production workshop more compact and rational, thus increasing space utilization. The lifting mechanism 11 is cylinder-driven, stable, reliable, simple in structure, and easy to maintain.

[0041] In summary, the working process of the end frame assembly equipment provided in this embodiment is as follows:

[0042] First, the distance between the two frames 1 and the distance between the first platform 21 and the second platform 22 are manually adjusted to match the length and width dimensions of the entire equipment with those of the end frame 3. Then, the column positioning assembly 5 and the crossbeam positioning assembly 4 are adjusted to their appropriate positions to ensure that the diagonal length, width, and relative positions of the components of the end frame 3 meet the requirements. During assembly, the column 32 is manually placed on the platform 2 and clamped by the second clamping cylinder 51; then the crossbeam 31 is manually placed and clamped by the first clamping cylinder 41, followed by manual spot welding for fixation. After welding is completed, the crossbeam positioning assembly 4 and the column positioning assembly 5 are fully opened, the drive device 9 pushes the two frames 1 apart, and the conveyor mechanism 10 simultaneously rises, lifting the assembled end frame 3 and conveying it to the next workstation.

[0043] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.
