Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and more specifically, to a flexible and adaptable steel component assembly jig. Background Technology
[0002] With the continuous innovation and adoption of new technologies in my country's spatial steel structure industry, the forms of building structures are becoming increasingly diverse, the spans are growing larger, and the structural systems are becoming more complex. When using integral lifting construction for large-span steel structures, the assembly of the structure needs to be completed on the ground. This assembly process requires a large number of assembly jigs. During continuous construction, after the steel components of each construction section are assembled, the assembly jigs need to be moved to the next construction section.
[0003] Among them, the patent with announcement number CN220365327U discloses a herringbone mobile steel component assembly frame. The steel component assembly frame includes a support platform and legs. The lower end of the legs is provided with bolt support components and rollers. The support platform is fixedly set on the upper end of the legs. The support platform is provided with an electromagnet adsorption component.
[0004] During the assembly of steel components, the jig can be moved to a designated position via rollers to provide support, improving the jig's movement efficiency. After the jig is moved to the designated position, the bolt support assembly can contact the ground to keep the jig stable. Then, the electromagnet adsorption assembly can adsorb and fix the steel component, allowing the steel component to be stably placed on the support platform, ensuring the jig's support stability. However, the jig is not easy to adjust the angle according to the requirements, which means that it needs to be reassembled when moving to different areas, which is cumbersome. At the same time, it is not easy to position the steel structure from multiple angles, resulting in low support stability. Summary of the Invention
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flexible and adjustable steel component assembly jig, which aims to solve the problems mentioned in the background art.
[0006] The present invention provides the following technical solution: a flexible adjustable steel component assembly jig, including a reinforcing plate, wherein support components are provided on both sides of the top of the reinforcing plate;
[0007] The support assembly includes a first deflection support plate disposed on one side of the top of the reinforcing plate, and a second deflection support plate with an adjustable angle is disposed at one end of the first deflection support plate.
[0008] The top of the first deflection support plate is provided with a position-adjustable reinforcing seat. Both sides of the reinforcing seat are hinged with extension seats, and each extension seat is rotatably connected with a first adapter adjustment rod. One end of each of the two first adapter adjustment rods is hinged with an angle-adjustable central member, and one end of the central member is hinged with an angle-adjustable second adapter adjustment rod.
[0009] One end of the reinforcing seat is hinged to a third adjustable adapter rod with an adjustable angle. One end of the third adjustable adapter rod is hinged to a fourth adjustable adapter rod with an adjustable angle. One end of the fourth adjustable adapter rod is hinged to a fifth adjustable adapter rod with an adjustable angle. A second electric push rod is hinged to the third adjustable adapter rod. The output end of the second electric push rod extends to and is hinged to the fourth adjustable adapter rod. A third electric push rod is hinged to the fourth adjustable adapter rod. The output end of the third electric push rod extends to and is hinged to the fifth adjustable adapter rod. A fourth electric push rod is hinged to the center member. The output end of the fourth electric push rod extends to and is hinged to the second adjustable adapter rod. Reinforcing diagonal rods are respectively provided on both sides of the top of the reinforcing plate. The reinforcing diagonal rods are hinged to the first deflection support plate. One end of the first deflection support plate is provided with an adjustable angle tripod. Both the first deflection support plate and the second deflection support plate extend to and are hinged to the tripod.
[0010] The bottom of the reinforcing seat is fixedly provided with a lower edge plate, and a first electric push rod is hinged to the lower edge plate. The output end of the first electric push rod extends to the third adapter adjustment rod and is hinged to the third adapter adjustment rod. A slide block is provided on the outer side of the first electric push rod. The slide block is fixed to the lower edge plate, and an electric slide rail is slidably connected to the bottom of the slide block.
[0011] As can be seen, in the above technical solution, the fourth electric push rod is activated, and its output end drives the second adapter adjusting rod to adjust the angle at the end of the first adapter adjusting rod. By adjusting the angle of the first adapter adjusting rod on the extension seat and locking it with bolts, it is easy to separate different steel components. At the same time, the output end of the first electric push rod extends and drives the third adapter adjusting rod to adjust the angle at the end of the reinforcing seat. The output end of the second electric push rod extends and drives the fourth adapter adjusting rod to adjust the angle at the end of the third adapter adjusting rod. The output end of the third electric push rod extends and drives... The fifth adapter adjustment rod is angled at the end of the fourth adapter adjustment rod. By adjusting the angles of the fourth, third, fifth, first, and second adapter adjustment rods, the fourth and second adapter adjustment rods can extend above the reinforcing seat to clamp and position the steel component. This also allows for adaptation to different steel components. Through flexible adjustment, it ensures that the height difference between various parts during assembly matches the drawings, thereby improving the accuracy of steel component assembly, reducing adjustment and correction work during assembly, and increasing assembly efficiency.
[0012] The tripod has traction rods rotatably connected to both sides of its bottom, and one end of each traction rod is rotatably connected to a vertical rod. The tops of both vertical rods extend to the bottom of the first deflection support plate and are rotatably connected to the first deflection support plate. A horizontal shaft is fixedly installed at the bottom of each of the two vertical rods. A first gear is rotatably connected to both sides of the reinforcing plate. An eccentric hole is opened on the first gear. The horizontal shaft is located in the eccentric hole and is rotatably connected to the eccentric hole. A servo motor is bolted to the bottom of the reinforcing plate. A second gear is provided at the output end of the servo motor. The second gear is located at the bottom of the first gear and meshes with the first gear. The electric slide rail is embedded in the first deflection support plate. Two support legs are bolted to the bottom of the reinforcing plate.
[0013] As can be seen, in the above technical solution, when the second gear rotates, it will drive the eccentric hole to make a circular motion along the axis of the first gear. This allows the horizontal shaft rod to be driven by the traction force when it is displaced through the eccentric hole, which in turn drives the vertical rod to deflect along the connection between the vertical rod and the first deflection support plate. When the vertical rod deflects, the traction rod drives the tripod to deflect along the connection between the tripod and the reinforcing diagonal rod. This causes the angle between the first deflection support plate and the second deflection support plate to change, so as to adapt to the shape and size of different steel components, meet the assembly requirements of different steel components, provide stable and accurate support and positioning, reduce the adjustment and correction work during the assembly process, and improve the assembly efficiency.
[0014] The technical effects and advantages of this invention are as follows:
[0015] 1. In this invention, the output end of the first electric push rod extends to drive the third adapter adjustment rod to adjust the angle at the end of the reinforcing seat. The output end of the second electric push rod extends to drive the fourth adapter adjustment rod to adjust the angle at the end of the third adapter adjustment rod. The output end of the third electric push rod extends to drive the fifth adapter adjustment rod to adjust the angle at the end of the fourth adapter adjustment rod. The output end of the fourth electric push rod drives the second adapter adjustment rod to adjust the angle at the end of the first adapter adjustment rod. By adjusting the angle of the first adapter adjustment rod on the extension seat and locking it with bolts, it is easy to separate different steel components.
[0016] 2. This invention, by adjusting the angles of the fourth, third, fifth, first, and second adapter adjusting rods, allows the fourth and second adapter adjusting rods to extend above the reinforcing seat, thereby clamping and positioning the steel component. It can also adapt to different steel components. Through flexible adjustment, it can ensure that the height difference of each part during assembly matches the drawings, thus improving the accuracy of steel component assembly, reducing adjustment and correction work during assembly, and improving assembly efficiency.
[0017] 3. The present invention enables the traction rod to drive the tripod to deflect along the connection between the tripod and the first deflection support plate when the vertical rod deflects, thereby changing the angle between the first deflection support plate and the second deflection support plate to adapt to different shapes and sizes of steel components, meet the assembly requirements of different steel components, and provide stable and accurate support and positioning.
[0018] In summary, the overall design is simple and the structure is reasonable. Through the corresponding use of various structures, and by adjusting the angles of the fourth, third, fifth, first, and second adapter adjustment rods, the fourth and second adapter adjustment rods can extend above the reinforcing seat to clamp and position the steel components. This design can also adapt to different steel components. Through flexible adjustment, it can ensure that the height difference of each part during assembly matches the drawings, thereby improving the accuracy of steel component assembly, reducing adjustment and correction work during assembly, and improving assembly efficiency. When the vertical rod deflects, the traction rod drives the tripod to deflect along the connection between the tripod and the first deflection support plate, which in turn changes the angle of the first and second deflection support plates to adapt to different shapes and sizes of steel components, meet the assembly requirements of different steel components, and provide stable and accurate support and positioning.

[0029] 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.
[0030] As attached Figure 1 - Figure 8 The flexible adjustable steel component assembly jig shown, through the support components set on the reinforcing plate 1, and through the corresponding cooperation of various structures, by adjusting the angles of the fifth adapter adjustment rod 10, the third adapter adjustment rod 8, the first adapter adjustment rod 6, and the second adapter adjustment rod 7, allows the fifth adapter adjustment rod 10 and the second adapter adjustment rod 7 to extend above the reinforcing seat 4, realizing the function of clamping and positioning the steel component. It can also adapt to different steel components. Through flexible adjustment, it can ensure that the height difference of each part during assembly matches the drawings, thereby improving the accuracy of steel component assembly, reducing the adjustment and correction work during the assembly process, and improving assembly efficiency. When the vertical rod 19 deflects, the traction rod 18 drives the tripod 16 to deflect along the connection between the tripod 16 and the first deflection support plate 2, thereby changing the angle of the first deflection support plate 2 and the second deflection support plate 3 to adapt to different shapes and sizes of steel components, meet the assembly requirements of different steel components, and provide stable and accurate support and positioning. The specific structural settings of the support components are as follows.
[0031] The support assembly includes a first deflection support plate 2 disposed on one side of the top of the reinforcing plate 1, and a second deflection support plate 3 with an adjustable angle is disposed at one end of the first deflection support plate 2.
[0032] The top of the first deflection support plate 2 is provided with a position-adjustable reinforcing seat 4. Both sides of the reinforcing seat 4 are hinged with extension seats 5, and each extension seat 5 is rotatably connected with a first adapter adjustment rod 6. One end of each of the two first adapter adjustment rods 6 is hinged with an angle-adjustable central member 28, and one end of the central member 28 is hinged with an angle-adjustable second adapter adjustment rod 7.
[0033] One end of the reinforcing seat 4 is hinged to a third adjustable adapter rod 8 with an adjustable angle. One end of the third adjustable adapter rod 8 is hinged to a fourth adjustable adapter rod 9 with an adjustable angle. One end of the fourth adjustable adapter rod 9 is hinged to a fifth adjustable adapter rod 10 with an adjustable angle. A second electric push rod 13 is hinged to the third adjustable adapter rod 8. The output end of the second electric push rod 13 extends to the fourth adjustable adapter rod 9 and is hinged to it. A third electric push rod 14 is hinged to the fourth adjustable adapter rod 9. The output end of the third electric push rod 14 extends to the fifth adjustable adapter rod. The fourth electric push rod 17 is hinged to the center member 28 and the output end of the fourth electric push rod 17 extends to the second adapter adjustment rod 7 and is hinged to the second adapter adjustment rod 7. The top two sides of the reinforcing plate 1 are respectively provided with reinforcing diagonal rods 15. The reinforcing diagonal rods 15 are hinged to the first deflection support plate 2, and one end of the first deflection support plate 2 is provided with an angle-adjustable tripod 16. The first deflection support plate 2 and the second deflection support plate 3 both extend to the tripod 16 and are hinged to the tripod 16.
[0034] The bottom of the reinforcing seat 4 is fixedly provided with a lower edge plate 11, and a first electric push rod 12 is hinged on the lower edge plate 11. The output end of the first electric push rod 12 extends to the third adapter adjustment rod 8 and is hinged to the third adapter adjustment rod 8. A slide seat 27 is provided on the outer side of the first electric push rod 12. The slide seat 27 is fixed on the lower edge plate 11, and an electric slide rail 26 is slidably connected to the bottom of the slide seat 27.
[0035] Both sides of the bottom of the tripod 16 are rotatably connected to traction rods 18, and one end of each traction rod 18 is rotatably connected to a vertical rod 19. The tops of the two vertical rods 19 extend to the bottom of the first deflection support plate 2 and are rotatably connected to the first deflection support plate 2. A horizontal shaft 20 is fixedly installed at the bottom of the two vertical rods 19. Both sides of the reinforcing plate 1 are rotatably connected to a first gear 21. An eccentric hole 22 is opened on the first gear 21. The horizontal shaft 20 is located in the eccentric hole 22 and is rotatably connected to the eccentric hole 22. A servo motor 23 is installed at the bottom of the reinforcing plate 1 by bolts. A second gear 24 is provided at the output end of the servo motor 23. The second gear 24 is located at the bottom of the first gear 21 and meshes with the first gear 21. An electric slide rail 26 is embedded in the first deflection support plate 2. Two support legs 25 are installed at the bottom of the reinforcing plate 1 by bolts.
[0036] According to the above structure, when in use, the staff installs the device at the designated position. During use, the servo motor 23 drives the second gear 24 to rotate. When the second gear 24 rotates, it will drive the eccentric hole 22 to make a circular motion along the axis of the first gear 21. This causes the horizontal shaft 20 to be driven by the traction force when it is displaced through the eccentric hole 22, which drives the vertical rod 19 to deflect along the connection between the vertical rod 19 and the first deflection support plate 2. When the vertical rod 19 deflects, the traction rod 18 drives the tripod 16 to deflect along the connection between the tripod 16 and the first deflection support plate 2. This causes the angle of the first deflection support plate 2 and the second deflection support plate 3 to change, so as to adapt to the shape and size of different steel components, meet the assembly requirements of different steel components, and provide stable and accurate support and positioning.
[0037] Furthermore, during use, it is activated by the fourth electric push rod 17. The output end of the fourth electric push rod 17 drives the second adapter adjustment rod 7 to adjust the angle at the end of the first adapter adjustment rod 6. By adjusting the angle of the first adapter adjustment rod 6 on the extension seat 5 and locking it with bolts, it is easy to constrain different steel components.
[0038] Simultaneously, the output end of the first electric push rod 12 extends to drive the third adapter adjustment rod 8 to adjust the angle at the end of the reinforcing seat 4. The output end of the second electric push rod 13 extends to drive the fourth adapter adjustment rod 9 to adjust the angle at the end of the third adapter adjustment rod 8. Then, the output end of the third electric push rod 14 extends to drive the fifth adapter adjustment rod 10 to adjust the angle at the end of the fourth adapter adjustment rod 9. By adjusting the angles of the fifth adapter adjustment rod 10, the third adapter adjustment rod 8, the first adapter adjustment rod 6, and the second adapter adjustment rod 7, the fifth adapter adjustment rod 10 and the second adapter adjustment rod 7 can extend above the reinforcing seat 4 to achieve the function of clamping and positioning the steel component. It can also adapt to different steel components. Through flexible adjustment, it can ensure that the height difference of each part during assembly matches the drawings, thereby improving the accuracy of steel component assembly, reducing the adjustment and correction work during the assembly process, and improving assembly efficiency.
[0039] Unlike existing technologies, this application discloses a flexible, adjustable steel component assembly jig. By adjusting the angles of the fifth, third, first, and second adjusting rods 10 and 7, the fifth and second adjusting rods 10 and 7 can extend above the reinforcing seat 4, achieving the function of clamping and positioning the steel component. It can also adapt to different steel components. Through flexible adjustment, it can ensure that the height difference of each part during assembly matches the drawings, thereby improving the accuracy of steel component assembly, reducing adjustment and correction work during assembly, and improving assembly efficiency. When the vertical rod 19 deflects, the traction rod 18 drives the tripod 16 to deflect along the connection between the tripod 16 and the first deflection support plate 2, thereby changing the angle of the first and second deflection support plates 2 and 3 to adapt to different shapes and sizes of steel components, meet the assembly requirements of different steel components, and provide stable and accurate support and positioning.

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.
