Description

Technical Field

[0001] The utility model relates to the field of engineering technology, in particular to a truss mechanical column adjusting system. Background Art

[0002] A truss is an important structural form widely used in engineering construction and mechanical design. It is mainly composed of straight bars connected by nodes to form stable triangular or polygonal structural units. The advantages of the truss structure lie in its high strength, light weight and efficient stress transfer characteristics, making it an indispensable element in large-span buildings, bridges, towers and various mechanical equipment.

[0003] During the use of the truss, high requirements are placed on the levelness and straightness, so the requirements for the truss columns are also very high. At present, the columns are all fixed structures. One end of the column is fixed on the ground, and the truss is fixedly installed at the other end of the column. Such installation has high requirements for the flatness of the bottom surface of the installation area and has strict requirements for the process flow of the installation procedure. Moreover, during actual use, if there are deviations in straightness and levelness, or when the height of the truss needs to be adjusted, the column needs to be unfixed and reinstalled, which is not easy to adjust. Summary of the Utility Model

[0004] Therefore, the utility model provides a truss mechanical column adjusting system to overcome the problem that the column is fixedly arranged during the use of the truss and is not easy to adjust according to needs after installation.

[0005] To achieve the above object, the utility model provides a truss mechanical column adjusting system, including:

[0006] A chemical expansion bolt, one end of which is screwed into the ground and the other end is connected to the bottom plate;

[0007] A height adjusting device, including a first adjusting nut, a hollow bolt and a second adjusting nut group. The first adjusting nut is provided with an internal thread and is matched with the external thread of the chemical expansion bolt. The hollow bolt is sleeved on the chemical expansion bolt and penetrates through the bottom plate. The second adjusting nut group includes an upper nut and a lower nut. The upper nut is arranged on the bottom plate and is attached to the bottom plate. The lower nut is arranged under the bottom plate and is attached to the bottom plate. Both the upper nut and the lower nut are provided with internal threads that are matched with the hollow bolt.

[0008] Further, a plurality of positioning through holes are arranged on the bottom plate in the vertical direction.

[0009] Further, a support body and a top plate are arranged above the bottom plate. The support body is fixedly connected to the bottom plate and the top plate respectively. The support body, the bottom plate and the top plate form a column.

[0010] Further, the positioning through holes are provided on the edge of the bottom plate.

[0011] Further, locking holes and locking screws are provided on the sides of the upper nut and the lower nut, and the locking holes are in threaded cooperation with the locking screws.

[0012] Further, support pieces are provided on the side of the column, and the support pieces are located between the positioning through holes.

[0013] Further, the first adjusting nut is provided above the hollow bolt.

[0014] Further, a flat washer is provided between the first adjusting nut and the hollow bolt.

[0015] Further, a floor gasket is sleeved below the hollow bolt.

[0016] Further, an elastic washer is provided on the flat washer, and the elastic washer is in contact with the chemical expansion bolt.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: through the threaded connection between the first adjusting nut and the chemical expansion bolt, and the threaded connection between the upper nut, the lower nut and the hollow bolt, a precise and flexible adjusting structure is formed. This dual adjusting mechanism greatly improves the accuracy and controllability of the column height adjustment. The first adjusting nut can perform rough adjustment on the chemical expansion bolt, while the upper nut and the lower nut achieve fine adjustment by adjusting their positions on the hollow bolt. The two work together to contribute to the precise adjustment of the truss. The design that the upper nut and the lower nut are respectively located above and below the bottom plate and are in close contact with it improves the stability and load-bearing capacity. This simple and effective structure can easily adjust the height of the truss according to actual needs, meet different working conditions and environmental requirements, and at the same time reduce the maintenance difficulty and cost and improve the service life.

[0018] Further, by providing four positioning through holes at the bottom plate to fix the column to the ground, not only the stability of the system is increased, but also the possibility of multi-point adjustment is provided, significantly improving the balance of the entire column and contributing to the free adjustment of the height of the bottom plate.

[0019] Further, locking holes and locking screws are provided on the sides of the upper nut and the lower nut, which helps to prevent the loosening of the nut during use and the resulting change in the column height. Support pieces are provided on the side of the support body between the positioning through holes, improving the stability and load-bearing capacity of the column. A flat washer is provided between the first adjusting nut and the hollow bolt, which helps to reduce friction and disperse pressure. By sleeving a floor gasket below the hollow bolt, it helps to increase the contact area between the hollow bolt and the ground and improve stability. Through the contact between the elastic washer and the chemical expansion bolt, vibration can be absorbed and loosening can be prevented. Description of the Drawings

The first adjusting nut 6 is provided with an internal thread and is matched with the external thread of the chemical expansion bolt 1. The hollow bolt 5 is sleeved on the chemical expansion bolt 1 and penetrates through the bottom plate 11. The second adjusting nut group includes an upper nut 4 and a lower nut 13. The upper nut is arranged on the bottom plate 11 and is attached to the bottom plate 11. The lower nut 13 is arranged under the bottom plate 11 and is attached to the bottom plate 11. Both the upper nut and the lower nut 13 are provided with internal threads that cooperate with the hollow bolt 5.

[0030] Specifically, the first adjusting nut 6 cooperates with the chemical expansion bolt 1 to fix the chemical bolt, and by adjusting the cooperation position of the first adjusting nut 6, a first adjusting distance for the hollow bolt 5 to move on the chemical expansion bolt 1 is formed. The upper nut 4 and the lower nut 13 fix the hollow bolt 5 on the bottom plate 11. By adjusting the cooperation positions of the upper nut 4 and the lower nut 13 on the hollow bolt 5, the fixing position of the bottom plate 11 on the hollow bolt 5 is changed to form a second adjusting distance for the bottom plate 11 to move on the hollow bolt 5. Both the first adjusting distance and the second adjusting distance are the truss height adjusting distances.

[0031] Specifically, through the threaded connection between the first adjusting nut 6 and the chemical expansion bolt 1, and the threaded connections between the upper nut 4, the lower nut 13 and the hollow bolt 5, a precise and flexible adjusting structure is formed. This dual-adjustment mechanism greatly improves the accuracy and controllability of height adjustment. The first adjusting nut 6 can perform rough adjustment on the chemical expansion bolt 1, while the upper nut 4 and the lower nut 13 achieve fine adjustment by adjusting their positions on the hollow bolt 5. The two work together to contribute to the precise adjustment of the truss. The design that the upper nut 4 and the lower nut are respectively located above and below the bottom plate 11 and are closely attached to it improves the stability and load-bearing capacity.
