Description

Technical Field

[0001] This utility model relates to the field of steel structure transportation technology, specifically a steel structure transportation fixing device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. These components are usually fabricated on-site and then transported to the construction site for installation. The components are typically connected by welding, bolting, or riveting. They are widely used in large factories, stadiums, irregularly shaped buildings, and bridges. The transportation of steel structures mainly utilizes trucks. Suitable vehicles are selected based on the size and weight of the steel structure. During transportation, to ensure stability, support and fixing devices are typically used to secure the steel structure to the vehicle. For example, patent CN221585251U discloses a support and fixing device for transporting ultra-long and ultra-wide irregularly shaped steel box girders. This device includes angle steel column support frames, adjusting timber 1, adjusting timber 2, and hand-operated hoists. The angle steel column support frames are installed in pairs on the lower side of the flatbed transport platform, and the pairs are horizontally connected by connectors. Adjusting timber 1 is placed on the top steel plate of the angle steel column support frame, and adjusting timber 2 is placed on the higher side of the flatbed transport platform. Hand-operated hoists are placed on both sides of the flatbed transport platform. This solution has the following drawbacks: Only the bottom of the steel structure is supported by angle steel column support frames, and the sides are secured using hand-operated hoists. Even with multiple sets of hand-operated hoists, if one or more hoists malfunction, the steel structure's position will become unstable, posing a high risk of falling and posing a safety hazard. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a steel structure transportation fixing device that solves the problem of unstable fixing in existing steel structure transportation support fixing devices.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a steel structure transportation fixing device, including a support frame for placing steel structure components and a hand-operated hoist. The bottom of the support frame is installed on the cargo platform of a flatbed transport vehicle. The hand-operated hoist is set on both sides of the cargo platform of the flatbed transport vehicle for binding the steel structure components. The support frame includes a base frame, uprights and crossbars. The side of the base frame is provided with several ear plates for connecting and fixing to the cargo platform of the flatbed transport vehicle. There are multiple uprights, which are vertically installed above the base frame by bolts and nuts. There are multiple crossbars and they are connected to the uprights by bolts. Multiple small cylindrical bars for binding the crossbars are spaced apart on the outside of the uprights.

[0005] Furthermore, both the uprights and crossbars are made of square tubing, which provides high structural strength, is easy to source, and has low manufacturing costs.

[0006] Furthermore, the bottom frame is made of square tubing welded together, and the ear plates are welded and fixed to the side of the bottom frame.

[0007] Furthermore, the crossbar is provided with U-shaped blocks at both ends, the inner side of the U-shaped blocks can pass through the column, and the U-shaped blocks are provided with bolt mounting holes. The U-shaped blocks can be used to easily adjust the height of the crossbar to adapt to steel structure components of different sizes.

[0008] Furthermore, multiple sets of the hand-operated hoists are installed along the length of the vehicle to ensure the stability of the steel structure components.

[0009] Furthermore, the ear plate is an upwardly curved bent plate, making the binding more stable and reliable.

[0010] The beneficial effects of this solution are as follows: Compared with the prior art, the steel structure transportation fixing device of this utility model fixes the steel structure components on the cargo platform of the flatbed transport vehicle by setting up a support frame and a manual hoist. The bottom frame of the support frame holds the steel structure components, and the columns and crossbars of the support frame work together to limit the lateral and longitudinal movement of the steel structure components, effectively preventing the steel structure components from falling and improving the safety of transportation. The device has a stable and reliable structure and is highly flexible in installation. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Implementation, for example, attached Figures 1 to 3The following describes a steel structure transport and fixing device, comprising a support frame 1 for placing steel structure components and a hand-operated hoist 2. The bottom of the support frame 1 is installed on the loading platform of a flatbed transport vehicle. The hand-operated hoists 2 are arranged on both sides of the loading platform of the flatbed transport vehicle for binding the steel structure components. Multiple sets of hand-operated hoists 2 are arranged along the length of the vehicle to ensure the stability of the steel structure components. The support frame 1 includes a base frame 11, uprights 13, and crossbars 14. The sides of the base frame 11 are provided with several ear plates 12 for connecting and fixing to the loading platform of the flatbed transport vehicle. The base frame 11 is made of welded square tubing. The ear plates 12 are welded and fixed to the sides of the base frame 11. The ear plates 12 can be tied to the loading platform by rope binding, so that the support frame 1 is firmly installed on the loading platform. The ear plates 12 are upwardly curved bent plates, making the binding more stable and reliable. The uprights 13 and crossbars 14 are both square tubing, with high structural strength. The materials are readily available and the manufacturing cost is low. Multiple uprights 13 are used, the number of which can be determined according to the size of the transported steel structure components. The uprights 13 are vertically installed above the base frame 11 using bolts and nuts to limit the lateral movement of the steel structure components. Multiple crossbars 14 are bolted to the uprights 13 to limit the longitudinal movement of the steel structure components, preventing them from falling. Multiple small cylindrical columns 15 are spaced apart on the outer side of the uprights 13 for binding the crossbars 14. The small cylindrical columns 15 can be straight or curved. After the crossbars 14 are installed, ropes are used to secure them tightly to the uprights 13. U-shaped blocks 16 are provided at both ends of the crossbars 14. The inner side of the U-shaped blocks 16 can pass through the uprights 13, and bolt mounting holes are provided on the U-shaped blocks 16. The U-shaped blocks 16 can be welded and fixed to the crossbars 14. The U-shaped blocks 16 allow for easy adjustment of the height of the crossbars 14 to accommodate steel structure components of different sizes. The specific implementation process is as follows: The bottom frame 11 of the support frame 1 is fixed to the cargo platform of the flatbed transport vehicle. The steel structure components are hoisted to the top of the bottom frame 11. If the steel structure components on the flatbed transport vehicle are placed in multiple layers, sleepers 3 are set between the components to prevent them from colliding and causing damage. When transporting cylindrical components, arc-shaped sleepers 3 can be set at the bottom of the components to prevent them from rolling. After the components are placed, the uprights 13 are installed on their outer side. The bottom frame 11 has multiple sets of bolt holes for installing the uprights 13. The number and position of the uprights 13 can be determined according to the size of the components. The uprights 13 on the left and right sides are connected by the crossbar 14, and the crossbar 14 is tied to the small cylindrical column 15 on the outside of the uprights 13 with ropes. Finally, the steel structure components are tied with a manual hoist. The uprights 13 and the crossbar 14 limit the horizontal and vertical movement of the steel structure components, respectively. Even if the manual hoist fails during transportation, the steel structure components will not fall off the side of the vehicle, which greatly improves transportation safety. Moreover, the installation process uses bolts and binding, which is flexible and convenient for disassembly and assembly.
