Description

Technical Field

[0001] This application relates to the field of steel transportation technology, and in particular to a limiting device for transporting ultra-long and ultra-wide special steel. Background Technology

[0002] In industrial sectors such as the production and construction of large bridges, heavy machinery, and nuclear power equipment, ultra-long and ultra-wide special steel materials (such as steel box girders with a length exceeding 12m and thick steel plates with a width exceeding 3m) are core components, and the safety and stability of their transportation directly determine the quality of subsequent construction.

[0003] In existing technologies, before loading and transporting extra-long and extra-wide special steel using large transport vehicles, the dimensions of the steel must be measured manually on the truck bed, and then steel blocks (such as angle steel and steel plates) must be cut and welded on-site to prevent lateral and longitudinal displacement of the extra-long and extra-wide special steel. After welding, the blocks are then reinforced by binding them point by point with plastic steel straps or steel wire ropes. Furthermore, the welded blocks need to be manually cut and removed after transportation, which not only damages the surface of the truck bed, leaving weld scars or deformation, but also makes it difficult to reuse the removed blocks due to poor size adaptability, resulting in resource waste. This method of limiting the loading of extra-long and extra-wide special steel is not only time-consuming and labor-intensive, but also has low work efficiency.

[0004] Therefore, we propose a limiting device for transporting ultra-long and ultra-wide special steel to solve the above problems. Utility Model Content

[0025] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] See Figures 1-6 This application provides a limiting device for transporting ultra-long and ultra-wide special steel, including a carrying platform 1 welded to a transport vehicle. The carrying platform 1 is used to place ultra-long and ultra-wide special steel. A baffle 2 is fixedly installed on the front top of the carrying platform 1. The carrying platform 1 is provided with multiple sets of evenly distributed lateral limiting mechanisms, which are used to limit the width of the ultra-long and ultra-wide special steel. The rear side of the carrying platform 1 is provided with multiple sets of evenly distributed longitudinal limiting mechanisms, which are used to limit the length of the ultra-long and ultra-wide special steel. Through the coordinated action of multiple sets of lateral and longitudinal limiting mechanisms, the ultra-long and ultra-wide special steel can be rigidly constrained in multiple directions, ensuring that the ultra-long and ultra-wide special steel is stably placed on the carrying platform 1, and fundamentally preventing displacement and tipping during transportation.

[0027] In this embodiment, the lateral limiting mechanism includes two widened secondary beams 4, two vertical stop beams 5, and a drive assembly. Symmetrically arranged transverse grooves 3 are provided on both sides of the top of the bearing platform 1. The two widened secondary beams 4 are slidably installed in their respective transverse grooves 3, with their ends extending away from each other to the outside of their respective transverse grooves 3. The two vertical stop beams 5 are welded to the ends of the two widened secondary beams 4 that are away from each other. The drive assembly 1 is used to adjust the distance between the two widened secondary beams 4. The drive assembly 1 includes a dual-axis motor 7 and two threaded rods 9. A groove 6 is provided at the bottom of the bearing platform 1. The dual-axis motor 7 is fixedly installed on the top inner wall of the groove 6. Threaded grooves 8 are provided at the ends of the two widened secondary beams 4 that are close to each other, and the two threaded rods 9 are threaded onto their respective threaded ends. Inside the slot 8, the ends of the two threaded rods 9 that are close to each other are fixedly connected to the two output shaft ends of the dual-axis motor 7. The top of the vertical stop beam 5 is welded with a binding lug 12. The dual-axis motor 7 is a reversible motor, and the two output shafts of the dual-axis motor 7 are set to rotate in the same direction. The threads of the two threaded rods 9 are set to rotate in opposite directions. Thus, when the dual-axis motor 7 drives the two threaded rods 9 to rotate forward or in reverse at the same time, the two widened sub-beams 4 can be controlled to slide in a direction away from each other or in a direction close to each other. Under the joint action of the two widened sub-beams 4, the ultra-long and ultra-wide special steel can be blocked and limited in the width direction. The binding lug 12 is designed to tie plastic steel strips or steel wire ropes along the width direction of the ultra-long and ultra-wide special steel to facilitate flexible reinforcement of the ultra-long and ultra-wide special steel.

[0028] In this embodiment, the longitudinal limiting mechanism includes a second vertical stop beam 14 and a second drive assembly. A mounting groove 13 is provided on the rear side of the bearing platform 1. The top and bottom of the mounting groove 13 are open. The bottom end of the second vertical stop beam 14 is located within the mounting groove 13. The second drive assembly is used to adjust the tilt angle of the second vertical stop beam 14. The second drive assembly includes a rotary motor 16, a bearing seat 17, and a rotating shaft 18. A second groove 15 is provided on the right inner wall of the mounting groove 13. The rotary motor 16 is fixedly installed in the second groove 15. The bearing seat 17 is fixedly installed on the left inner wall of the mounting groove 13. The left end of the rotating shaft 18 is rotatably connected to the bearing seat 17, and the right end of the rotating shaft 18 is fixedly connected to the output shaft end of the rotary motor 16. The bottom end of the second vertical stop beam 14 is fixedly sleeved on the rotating shaft 18. A second binding lug 20 is welded to the top of the second vertical stop beam 14, and a third binding lug 21 is welded to the top of the baffle 2. The rotary motor 16 is reversible. The rotary motor 16 drives the rotating shaft 18 to rotate, which in turn allows the vertical stop beam 14 to rotate around the rotating shaft 18, thus adjusting the tilt angle of the vertical stop beam 14. When the length of the extra-long and extra-wide special steel is slightly less than the length of the bearing platform 1, the vertical stop beam 14 can be rotated and adjusted to tilt upwards to abut the tail of the extra-long and extra-wide special steel, thereby blocking and limiting the extra-long and extra-wide special steel in the length direction. When the length of the extra-long and extra-wide special steel is slightly greater than the length of the bearing platform 1, the vertical stop beam 14 can be rotated and adjusted to a horizontal state to support the tail of the extra-long and extra-wide special steel. Using the binding lugs 20 and 31, plastic steel straps or steel wire ropes can be tied along the length direction of the extra-long and extra-wide special steel, thereby flexibly reinforcing the extra-long and extra-wide special steel in the length direction and achieving blocking and limiting of the extra-long and extra-wide special steel in the length direction.

[0029] In this embodiment, clearance holes 10 are provided on both inner walls of the groove 6. The two clearance holes 10 are connected to the corresponding transverse grooves 3 respectively. The ends of the two threaded rods 9 that are close to each other pass through the corresponding clearance holes 10. The design of the clearance holes 10 can ensure that the threaded rods 9 rotate smoothly.

[0030] In this embodiment, the upper surface of the widened sub-beam 4 is flush with the upper surface of the bearing platform 1, which can ensure that the widened sub-beam 4 and the bearing platform 1 are evenly subjected to the gravity of the ultra-long and ultra-wide special steel, thereby enhancing the stability of the ultra-long and ultra-wide special steel placed on the bearing platform 1.

[0031] In this embodiment, an anti-slip rubber pad 11 is fixedly installed on one side of the vertical beam 5, located above the widened sub-beam 4. The design of the anti-slip rubber pad 11 can prevent the vertical beam 5 from making hard contact with the ultra-long and ultra-wide special steel, and will not damage the outer surface of the ultra-long and ultra-wide special steel.

[0032] In this embodiment, an anti-slip rubber pad 2 19 is fixedly installed on the front side wall of the vertical support beam 2 14. The design of the anti-slip rubber pad 2 19 can prevent the vertical support beam 2 14 from making hard contact with the ultra-long and ultra-wide special steel, and will not damage the outer surface of the ultra-long and ultra-wide special steel.

[0033] In this embodiment, the upper surface of the support platform 1 is provided with anti-slip texture. The anti-slip texture design can increase the friction when the ultra-long and ultra-wide special steel comes into contact with the support platform 1, and further enhance the stability of the ultra-long and ultra-wide special steel placed on the support platform 1.

[0034] In this embodiment, the supporting platform 1, baffle 2, widened sub-beam 4, vertical baffle 5, baffle 14, binding lug 12, binding lug 20, and binding lug 3 21 are all made of steel, and the surfaces of the widened sub-beam 4, vertical baffle 5, baffle 14, binding lug 12, binding lug 20, and binding lug 3 21 are all coated with anti-rust paint. The dual-axis motor 7 and the rotary motor 16 can be electrically connected to the vehicle power supply and vehicle control switch on the transport vehicle through wires. The vehicle power supply is used to supply power to the dual-axis motor 7 and the rotary motor 16, and the vehicle control switch is used to control the operation of the dual-axis motor 7 and the rotary motor 16 respectively. The wiring connection method and control method are mature technologies in this field and have been fully disclosed, so they will not be described again in this article.

[0035] With the above structure, the ultra-long and ultra-wide special steel loading and limiting device provided in this application, when in use, welds and fixes the bearing platform 1 to the transport vehicle to form a rigid connection, ensuring the stability during subsequent transportation of ultra-long and ultra-wide special steel, and connects the power cord; when loading and transporting ultra-long and ultra-wide special steel, firstly, according to the width dimension of the ultra-long and ultra-wide special steel, the dual-axis motor 7 is controlled to rotate forward. The two output shafts of the dual-axis motor 7 drive the corresponding threaded rods 9 to rotate simultaneously, utilizing the threaded connection between the two threaded rods 9 and the corresponding threaded grooves 8. The two symmetrically widened sub-beams 4 can be controlled to move away from each other. The two widened sub-beams 4 drive the corresponding vertical stop beams 5 to move. At this time, the distance between the two vertical stop beams 5 gradually increases. When the distance between the two symmetrically widened vertical stop beams 5 is adjusted to be greater than the width of the extra-long and extra-wide special steel, the dual-axis motor 7 stops running and then the rotary motor 16 is controlled to rotate forward. The rotary motor 16 drives the rotating shaft 18 to rotate forward, so that the second stop beam 14 rotates forward with the rotating shaft 18 as the center. When the second stop beam 14 is rotated to a horizontal state, the rotary motor 16 stops running.

[0036] Then, using cranes and other equipment, the extra-long and extra-wide special steel is lifted and transferred to the bearing platform 1, ensuring that the front end of the extra-long and extra-wide special steel is in contact with the baffle 2. Then, by controlling the dual-axis motor 7 to run in reverse, the two symmetrically widened sub-beams 4 can be controlled to move closer to each other. At this time, the distance between the two vertical baffles 5 gradually decreases. When the anti-slip rubber pads 11 on the two vertical baffles 5 are in tight contact with the outer wall of the extra-long and extra-wide special steel, the dual-axis motor 7 is stopped. At this time, the symmetrical vertical baffles 5 can be used to block and limit the extra-long and extra-wide special steel in the width direction. Then, plastic steel belts or steel wire ropes are used to wrap around the top of the extra-long and extra-wide special steel and tie both ends to the binding ears 12 at the top of the symmetrical vertical baffles 5. This can flexibly reinforce the extra-long and extra-wide special steel in the width direction, thereby achieving the effect of stabilizing and limiting the extra-long and extra-wide special steel in the width direction.

[0037] Next, the angle of the second retaining beam 14 is adjusted according to the length of the extra-long and extra-wide special steel. When the length of the extra-long and extra-wide special steel is slightly smaller than the length of the bearing platform 1, the rotary motor 16 is reversed. The rotary motor 16 drives the rotating shaft 18 to rotate in the opposite direction, causing the second retaining beam 14 to rotate in the opposite direction around the rotating shaft 18. When the anti-slip rubber pad 19 on the second retaining beam 14 rotates to press against the tail of the extra-long and extra-wide special steel, the rotary motor 16 is stopped. At this time, the second retaining beam 14, in conjunction with the baffle 2, can block and limit the extra-long and extra-wide special steel in the length direction. Then, a plastic steel belt or steel wire rope is used to wrap around the top of the extra-long and extra-wide special steel and tie its two ends to the vertical retaining beam 1. The top binding lug 20 and the top binding lug 3 21 of the baffle 2 can flexibly reinforce the extra-long and extra-wide special steel along the length direction. When the length of the extra-long and extra-wide special steel is slightly larger than the length of the bearing platform 1, it is not necessary to control the rotary motor 16 to reverse. At this time, the tail of the extra-long and extra-wide special steel can be supported by the second baffle beam 14. By using plastic steel belt or steel wire rope to wrap around the top of the extra-long and extra-wide special steel, its two ends are tied and tightened to the top binding lug 20 of the vertical baffle beam 14 and the top binding lug 3 21 of the baffle 2, respectively. This can flexibly reinforce the extra-long and extra-wide special steel along the length direction, thereby achieving the effect of stabilizing and limiting the extra-long and extra-wide special steel along the length direction.

[0038] After securing and limiting the extra-long and extra-wide special steel along both the length and width directions, the transport vehicle can be driven away to transport the extra-long and extra-wide special steel to its destination. During transportation, it can be ensured that the extra-long and extra-wide special steel will not shift or tip over.
