Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a shock-absorbing steel structure. Background Art

[0002] In many industrial and engineering fields, the stable operation of machines and equipment is the key to maintaining production efficiency and ensuring operational safety. To this end, it is particularly important to design and implement effective vibration reduction solutions. Shock-absorbing steel structures came into being to provide stable support for machines and equipment while effectively alleviating the vibration caused by machine operation.

[0003] Steel structures are widely used in the fields of construction and machinery due to their high strength, good plasticity, and ease of manufacturing and assembly, including as temporary or long-term support structures for machines. Such structures are generally equipped with shock absorbers or other shock-absorbing elements to absorb and disperse the vibration energy generated by the operation of the machine, preventing these vibrations from being transmitted to the ground or surrounding structures, thereby protecting the stable operation of the equipment and extending its service life.

[0004] However, although existing shock-absorbing steel structures can largely achieve the desired shock-absorbing effect, there is a significant shortcoming: the contact force cannot be adjusted. The shock-absorbing structure relies on its preset or fixed shock-absorbing capacity to absorb and disperse vibration energy, but cannot be adjusted accordingly according to the different vibration forces generated by the machine during movement. Since the operating state of the machine may change due to factors such as load, speed or working environment, the vibration force it generates will also change accordingly. When the vibration force exceeds the optimal shock absorption range of the shock-absorbing structure, the shock absorption effect will be greatly reduced, which will affect the stability and long-term performance of the machine, and may even cause damage to the machine itself or other structures.

[0005] To this end, it is urgent to develop a new type of shock-absorbing steel structure system, which should have an adaptive adjustment function and be able to dynamically adjust the contact force according to the vibration intensity generated when the machine is running, to ensure that the optimal shock-absorbing effect can be provided under different working conditions.

[0009] By twisting the adjusting ring to move it, the spring is squeezed and deformed, causing the subsequent compression force to gradually increase. Through such a setting, the purpose of adjusting the shock absorbing force can be achieved. Such a setting is mainly used to select the appropriate shock absorbing force for use according to the vibration conditions.

[0010] In a preferred solution, the bottom of the upper connecting plate is symmetrically rotatably connected to a first rotating rod, both sides of the top rod are rotatably connected to second rotating rods, and the second rotating rod is rotatably connected to one end close to the first rotating rod.

[0011] Through such an arrangement, the first rotating rod and the second rotating rod can be connected and the stability of the connection can be ensured.

[0012] In a preferred solution, a sleeve is slidably connected to the outer side of the push rod, a through groove is provided on the outer side of the sleeve, and the through groove is provided in a through structure.

[0013] The top rod can slide inside the sleeve, so that the use height of the device can be adjusted.

[0014] In a preferred solution, a square-structured limiting ring is provided on the outer side of the sleeve, and a connecting block is fixedly connected to the inside of the limiting ring and the inside of the through slot, and the connecting block is slidably connected to the corresponding through slot, and the connecting block is fixedly connected to the push rod.

[0015] When the push rod moves, the limit ring can be driven to move through the connecting block.

[0016] In a preferred solution, the sleeve and the limiting ring are both provided with limiting holes, and screws are installed between the corresponding limiting holes to achieve positioning of the push rod and the sleeve.

[0017] With such an arrangement, the limiting ring can be fixed by the screw rod, and then the push rod can be fixed by the limiting ring.

[0018] In a preferred solution, a lower connecting plate is fixedly connected to the bottom of the sleeve, and mounting holes are provided on the lower connecting plate and the upper connecting plate.

[0019] The lower connecting plate is used to connect the bottom, and the upper connecting plate is used to connect the top.
