Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength measurement, and more specifically to a device for controlling the synchronous sliding of a large-span steel truss. Background Technique

[0002] A steel truss is a truss structure made of steel, which is widely used in load-bearing structures such as the roof structures of industrial and civil buildings, crane beams, bridges, hydraulic gates, and various types of towers. A steel truss is a lattice load-bearing structure, and the members made of steel are connected at both ends by welding, riveting, or bolting. This structure can make full use of the strength of the material. Especially when the span is relatively large, compared with a solid web beam, it can significantly save materials, reduce self-weight, and increase stiffness.

[0003] In the construction of large-span building structures, steel trusses are favored due to their excellent mechanical properties and economy. For particularly large spans, such as the roof structures of stadiums and convention centers, traditional hoisting methods may be difficult to implement due to limitations in the capacity of lifting equipment and construction space. At this time, the sliding technology of large-span steel trusses has become an efficient and economical construction plan. As the name implies, the sliding technology of large-span steel trusses is an installation method in which the steel truss structure is horizontally moved as a whole or in sections to the designed position on a pre-set slideway by using traction equipment. This technology can significantly reduce the amount of high-altitude work, lower the construction difficulty and risk, and improve the construction efficiency at the same time.

[0004] Existing large-span steel trusses need to move synchronously during operation. The traditional moving method has a large friction force and the fixture seat is clamped from both sides, which easily causes deformation of the track. Therefore, a new technical solution is needed to solve this problem. Content of the Utility Model

On the side of the clamping seat 8, there is arranged a second fixing frame 7. Inside the first fixing frame 4, there is arranged a first hydraulic cylinder 5, and at the power output end of the first hydraulic cylinder 5, there is arranged a telescopic rod 6.

On the upper part of the clamping seat 8, there is arranged a second hydraulic cylinder 9, and at the output end of the second hydraulic cylinder 9, there is arranged a driving rod 17. Inside the clamping seat 8, there is arranged a receiving groove 16, and inside the receiving groove 16, there is arranged a pressing block 18. The driving rod 17 extends into the receiving groove 16 of the clamping seat 8 and is connected to the pressing block 18. On the side of the first hydraulic cylinder 5, there is arranged a first joint 10, and on the side of the second hydraulic cylinder 9, there is arranged a second joint 15. Both the first joint 10 and the second joint 15 are connected to a pump source through pipelines. On the surface of the track 1, there are arranged a sliding seat 2 and a clamping seat 8, and both the sliding seat 2 and the clamping seat 8 are mutually fitted with the track 1. On the upper part of the sliding seat 2, there is arranged a member mounting frame 3, and on the side of the member mounting frame 3, there is arranged a first fixing frame 4. On the side of the clamping seat 8, there is arranged a second fixing frame 7. Inside the first fixing frame 4, there is arranged a first hydraulic cylinder 5, and at the power output end of the first hydraulic cylinder 5, there is arranged a telescopic rod 6. At the head end of the telescopic rod 6, there is arranged a connecting block 14, and the connecting block 14 is connected to the second fixing frame 7. On the upper part of the clamping seat 8, there is arranged a second hydraulic cylinder 9, and at the output end of the second hydraulic cylinder 9, there is arranged a driving rod 17. Inside the clamping seat 8, there is arranged a receiving groove 16, and inside the receiving groove 16, there is arranged a pressing block 18. The driving rod 17 extends into the receiving groove 16 of the clamping seat 8 and is connected to the pressing block 18.

Both the first joint 10 and the second joint 15 are connected to a pump source through pipelines. When in use, the steel truss is installed on the member mounting frame 3. At the same time, the second hydraulic cylinder 9 is controlled by the pump source to drive the driving rod 17 to extend, so that the pressing block 18 contacts the track 1. Since the clamping seat 8 and the track 1 are mutually fitted, they receive force interaction, so that the clamping seat 8 is fixed on the surface of the track 1. Compared with fixing from both sides, its firmness is better. At the same time, the first hydraulic cylinder 5 is started to drive the telescopic rod 6 to expand and contract, so as to push the sliding seat 2 to move, realizing the sliding operation of the steel truss. Multiple sets of sliding mechanisms perform synchronous operations through a synchronous operating system to realize the synchronous sliding of the large-span steel truss.

At the same time, the first hydraulic cylinder 5 retracts the telescopic rod 6, and the clamping seat 8 moves towards the sliding seat 2, and repeated operations can be carried out.

[0023] Further improved, such as Figure 3 shown: The track 1 is arranged in an I-shaped structure, and sliding grooves matching with it are arranged inside the sliding seat 2 and the clamping seat 8. This setting ensures the stability of the installation.

[0024] Further improved, such as Figure 1 shown: The first hydraulic cylinder 5 is rotatably connected to the first fixing frame 4. This setting enables the first hydraulic cylinder 5 to freely adjust the angle during the pushing process, thus ensuring the pushing angle.

[0025] Further improved, such as Figure 2 shown: The second hydraulic cylinder 9 drives the mounting plate 11 arranged on the top. A connecting rod 12 is arranged inside the mounting plate 11. The bottom of the connecting rod 12 is fixedly connected to the clamping seat 8, and the top extends outside the mounting plate 11. A locking nut 13 is arranged on the top of the connecting rod 12. The connecting rod cooperates with the mounting plate and the locking nut to effectively fix the second hydraulic cylinder 9 and provide certain protection.

[0026] Further improved, such as Figure 6 shown: A groove 19 is arranged inside the sliding seat 2, and a mounting groove 20 is arranged inside the groove 19. A roller shaft 21 is arranged inside the mounting groove 20, and a roller 22 is arranged on the surface of the roller shaft 21. The roller 22 is in contact with the surface of the track 1.

A second hydraulic cylinder 9 is arranged on the upper part of the clamping seat 8, and a driving rod 17 is arranged at the output end of the second hydraulic cylinder 9. A receiving groove 16 is arranged inside the clamping seat 8, and a pressing block 18 is arranged inside the receiving groove 16. The driving rod 17 extends into the receiving groove 16 of the clamping seat 8 and is connected to the pressing block 18. A first joint 10 is arranged on the side of the first hydraulic cylinder 5, and a second joint 15 is arranged on the side of the second hydraulic cylinder 9. Both the first joint 10 and the second joint 15 are connected to the pump source through pipelines. During use, install the steel truss on the element mounting frame 3. At the same time, control the second hydraulic cylinder 9 to drive the driving rod 17 to extend through the pump source, so that the pressing block 18 contacts the track 1. Since the clamping seat 8 and the track 1 are mutually engaged, they receive the interaction of forces, so that the clamping seat 8 is fixed on the surface of the track 1. Compared with fixing from both sides, its firmness is better. At the same time, start the first hydraulic cylinder 5 to drive the telescopic rod 6 to expand and contract, so as to push the sliding seat 2 to move, realizing the sliding operation of the steel truss. Multiple sets of sliding mechanisms perform synchronous operations through a synchronous operating system to realize the synchronous sliding of the large-span steel truss. After the sliding is completed, the second hydraulic cylinder 9 retracts the pressing block 18 to release the clamping seat 8, and the sliding seat 2 is fixed under the action of gravity. At the same time, the first hydraulic cylinder 5 retracts the telescopic rod 6, and the clamping seat 8 moves towards the sliding seat 2, and repeated operations can be carried out.
