Description

Technical Field

[0001] This utility model belongs to the field of transportation technology for large steel components in building engineering, specifically a transportation frame for large steel pipe arch trusses. Background Technology

[0002] Large steel pipe arch trusses are widely used in large buildings such as stadiums, museums, railway stations, and material yards due to their ability to achieve large-span structures. These arch trusses have large cross-sectional dimensions, are heavy, and have an arched shape, making them typical examples of oversized / overweight transport. Currently, the conventional practice is to assemble them near the site and then transport them in sections to the installation site. If vertical transport is used, the problem of a high center of gravity arises, placing extremely high demands on transport technology and safety.

[0003] However, existing methods for transporting large steel pipe arch trusses still have certain problems: when using vertical transport, due to the high center of gravity, long components, and special shape of the arch truss, it is prone to swaying, sliding, or even overturning during transport, posing a serious challenge to transport stability. At the same time, the lack of dedicated, high-strength support and fixing devices makes it difficult to effectively prevent deformation and damage to components due to sliding or vibration during transport, and the versatility and reusability of transport equipment are often insufficient.

[0004] To address the aforementioned issues, there is an urgent need to develop a specialized transport frame that is high in strength, has a strong load-bearing capacity, can stably fix the arch truss, and can be reused. Utility Model Content

[0005] The purpose of this utility model is to provide a large steel pipe arch truss transport frame to solve the problems mentioned in the background art, such as high center of gravity and long components leading to poor transport stability, easy slippage, overturning and component deformation damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large steel pipe arch truss transport frame, including an axle vehicle, a steel pipe arch truss, a bottom beam, columns, stiffening plates, connecting rods, pins, lower diagonal braces, upper diagonal braces, connecting plates, short beams, screw rods, supports, lower connecting beams, and upper connecting beams; The two ends of the bottom beam are welded and fixed to the bottom of the two columns respectively, and connecting plates are welded to the bottom beam and the columns in the connection area respectively. The two ends of the two lower diagonal braces are respectively welded to the connecting plate located on the bottom beam and the connecting plate located on the column; A stiffening plate is welded to the bottom beam at the stress concentration point where the bottom beam connects to the column; The top of each of the two columns is welded with a short beam, and an upper diagonal brace is welded to the connection area between the column and the short beam. The two ends of the connecting rod are connected to the short beams on both sides by a pin. A lead screw is welded and installed on the upper surface of the short beam, and a support for supporting the steel pipe arch truss is installed on the top of the lead screw, thus forming a single transport frame. The lower parts of the two individual transport frames are connected and fixed by a lower connecting beam, and the upper parts are connected and fixed by an upper connecting beam, forming a transport frame group; The lead screw can be adjusted to lift and lower so that the support is tightly attached to and fixed to the steel pipe arch truss placed on it.

[0007] Preferably, the lower and upper diagonal braces, together with the bottom beam, column, and short beam, form a stable triangular support structure.

[0008] By adopting the above technical solution, the triangular structure significantly enhances the frame unit's ability to resist lateral forces, bending and torsion, ensuring overall rigidity and stability during transportation.

[0009] Preferably, the stiffening plate is welded to the concentrated stress position where the bottom beam connects to the column.

[0010] By adopting the above technical solution, the stiffening plate effectively disperses and transmits concentrated stress at the connection, prevents weld cracking or local deformation, and improves the load-bearing capacity and durability of key nodes.

[0011] Preferably, the upper surface of the support is shaped to fit the outer wall of the steel pipe arch truss.

[0012] By adopting the above technical solution, the contact area between the support and the arch truss is increased, providing more uniform support and friction, and reducing local stress concentration and the risk of sliding.

[0013] Preferably, the connecting rod is connected to the short beam via a pin.

[0014] By adopting the above technical solution, the pin connection strengthens the overall integrity, facilitates quick installation and disassembly, and improves turnover efficiency.

[0015] Preferably, the lower connecting beam and the upper connecting beam weld the two individual transport frames together to form a transport frame assembly.

[0016] The above technical solution greatly enhances the stability and structural strength of the single transport frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: Stable structure and controllable center of gravity: The rigid frame structure composed of bottom beams, columns, diagonal braces and connecting beams, as well as adjustable supports, effectively reduces the center of gravity height and lateral tilt risk when transporting ultra-long, arched steel pipe trusses vertically, and greatly improves transportation stability.

[0018] Preventing sliding deformation: The support fits tightly against the curved surface of the truss, and with the constraints of the adjustable screw and connecting rod, the truss is firmly fixed, effectively preventing sliding, displacement, and component deformation damage caused by vibration or inertia during transportation.

[0019] Safe and reliable: stiffening plates enhance key nodes; diagonal braces form a stable triangular support structure, resulting in high overall structural strength and load-bearing capacity, ensuring safe and reliable transportation during long-distance or complex road conditions.

[0020] Easy to install and efficient to turn around: The main components are connected by welding and pins, the structure is clear, and on-site assembly and disassembly are convenient and quick; the frame design is sturdy and durable, reusable, and reduces transportation costs.
