Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure transportation technology in building construction, specifically a shock-absorbing device for handling steel structures during building construction. Background Technology
[0002] In building construction, the on-site handling of steel structures (composed of steel materials and one of the main building structure types) requires different methods depending on their size: larger steel structures rely on cranes for transport, while smaller steel structures are mostly moved using transport vehicles. However, traditional transport vehicles for steel structures have significant technical limitations, making it difficult to meet the requirements of construction efficiency and component protection.
[0003] These types of transport vehicles typically rely on manual pushing and pulling operations. However, construction site surfaces are generally uneven (e.g., potholes, piles of gravel), resulting in excessive vibration during transport. This vibration is not only directly transmitted to the steel structure (especially causing deformation and surface damage to thin-walled and precision components), but also exacerbates component swaying due to the bumps. Multiple construction workers are required to work together to support the components and prevent them from slipping, increasing labor costs and severely reducing construction efficiency. Furthermore, traditional transport vehicles lack targeted fixing and shock absorption designs. Fixing often relies on simple binding, which has poor adaptability to steel structures of different sizes and is prone to loosening due to vibration. Moreover, the lack of effective shock absorption mechanisms means that long-term vibration not only damages components but also accelerates the wear and tear of transport vehicle parts.
[0004] Therefore, those skilled in the art have provided a vibration damping device for transporting steel structures in building construction to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a shock-absorbing device for transporting steel structures in building construction, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A shock-absorbing device for transporting steel structures in building construction includes a trolley body, guide rails, a shock-absorbing plate, and a clamping plate. The trolley body has a rectangular opening running vertically through its center. Two guide rails are installed within the rectangular opening, with the guide rails fixedly mounted on the inner walls of the left and right sides of the rectangular opening.

Limiting rings are provided on the outer wall of the upper end of the slide rod. The limiting rings are fixedly connected to the slide rod and can restrict the shock-absorbing plate to the slide rod.
[0008] As a further embodiment of this utility model: each of the upper ends of the slider 1 is provided with a lower connecting member 1, wherein the lower connecting member 1 is fixedly connected to the slider 1; each of the lower ends of the fixing plate is provided with an upper connecting member 1, wherein the upper connecting member 1 is attached to the fixing plate; one end of the connecting rod 1 is rotatably connected to the upper connecting member 1, and the other end of the connecting rod 1 is rotatably connected to the lower connecting member 1; each of the upper ends of the slider 2 is provided with a lower connecting member 2, wherein the lower connecting member 2 is fixedly connected to the slider 2.
[0009] As a further embodiment of this utility model: each of the fixed plates is provided with a lower connecting member 2, wherein the lower connecting member 2 is attached to the fixed plate, one end of the connecting rod 2 is rotatably connected to the upper connecting member 2, and the other end of the connecting rod 2 is rotatably connected to the lower connecting member 2, and the slider 1 and slider 2 are locked in the slide groove, and the slider 1 and slider 2 are located between the front and rear reset springs.
[0010] As a further embodiment of this utility model: the upper end of the shock absorber plate is provided with a movable groove, and a bidirectional lead screw is provided in the movable groove. The bidirectional lead screw is rotatably connected to the shock absorber plate, and two movable blocks are threadedly connected to the bidirectional lead screw. The movable blocks are locked in the movable groove, and a clamping plate is fixedly connected to the upper end of each movable block.
[0011] As a further embodiment of this utility model: a rotating disk is provided at one end of the bidirectional lead screw, wherein the rotating disk is fixedly connected to the bidirectional lead screw, and locking universal wheels are provided at the four corners of the lower end of the trolley body, wherein the locking universal wheels are bolted to the trolley body, and two left and right support rods are fixedly connected to the front end of the trolley body, and a push rod is fixedly connected between the support rods.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. High-efficiency shock absorption and thorough protection: When the shock-absorbing plate slides up and down due to bumps, the vertical vibration is converted into the horizontal displacement of the slider along the spring rod through the connecting rod. The vibration energy is absorbed by the elastic deformation of the return spring. The cross rotation design of the connecting rod disperses stress and avoids impact damage to the surface of the steel structure. It is especially suitable for precision and easily deformable components.
[0014] 2. Precise clamping and reliable anti-detachment: Adopting the "two-way lead screw + opposing moving block" design, the clamping plate can be symmetrically contracted / opened by manually rotating the turntable. The reverse thread of the lead screw achieves synchronous centering and clamping, with uniform force to avoid skewing. It is suitable for steel structures of different sizes, replacing the traditional binding fixation and reducing the risk of steel structure loosening during transportation.

Slider 17 and slider 22 are engaged in the slide groove 14, and the sliders... 17 and slider 22 are located between the front and rear return springs 16.

[0024] The working principle of this utility model is as follows: During the clamping stage, the steel structure can be placed in the middle of the shock-absorbing plate 9. Then, the rotating disk 8 is manually rotated to drive the bidirectional lead screw 7 to rotate. Utilizing the reverse threads at both ends of the lead screw 7, the left and right moving blocks 6 are driven to move towards each other along the moving groove 10, simultaneously causing the clamping plate 5 to retract towards the center, forming a symmetrical clamping of the steel structure. This ensures uniform force distribution and prevents slippage due to bumps during transport. During transport, the push rod 4 is pushed to move freely using the flexibility of the locking caster 2. When encountering bumps, the shock-absorbing plate 9 slides up and down along the slide rod 11, and the vertical... The vertical vibration is converted into horizontal displacement of the slider on the spring rod 15. The slider compresses the return springs 16 on both sides, and absorbs the vibration energy by using elastic deformation, which greatly reduces the impact on the steel structure. During unloading, the rotating disk 8 is rotated in the opposite direction to release the clamping plate 5 and lock the universal wheel to fix the position of the trolley, so that the steel structure can be easily removed. In this way, the whole device solves the pain points of easy slippage, vibration damage and inconvenient operation of steel structure handling in building construction by the system coordination of "centering clamping to prevent falling, connecting rod spring to eliminate bumps and universal wheel group to facilitate movement", thus improving the safety and efficiency of handling.
