Description

Technical Field

[0001] This invention belongs to the field of steel transportation and fixing technology, and particularly relates to a steel transportation and fixing structure. Background Technology

[0002] Currently, steel coils can be transported using either ordinary trucks with simple rope binding and padding, or specialized trucks with dedicated V-shaped wedges and rope binding. While both methods meet the basic transportation needs for short distances on flat roads, they have gradually revealed many shortcomings in actual long-distance or complex road conditions, making them unsuitable for the characteristics of steel coils, such as their large weight, smooth surface, and high inertia.

[0003] Specifically, there are two major safety hazards during the transportation of steel coils: First, when the transport vehicle travels on bumpy roads, the vehicle will experience continuous up-and-down and left-and-right vibrations, which will be directly transmitted to the steel coils. Under the influence of vibration, the coils are prone to displacement, resulting in problems such as loosening of binding ropes and displacement of padding blocks, which will further aggravate the swaying of the steel coils and increase the risk of transport. Second, when the vehicle encounters an emergency and needs to brake suddenly, the steel coils have strong inertia due to their large mass, which will generate a huge impact force along the direction of vehicle travel. Since adjacent steel coils are independently fixed, the load-bearing capacity and limiting effect of the existing fixing structure are limited and cannot effectively counteract this inertial impact force. This can easily lead to the steel coils shifting or sliding violently, or even rolling off the transport vehicle.

[0004] Therefore, for situations requiring the transportation of large quantities of steel coils, there is an urgent need to develop a steel transportation and fixing structure that can enhance the stability of steel coil fixing, offset inertial impact forces, and prevent steel coil displacement, in order to solve the safety hazards existing in the current technology and improve the safety and reliability of steel coil transportation. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a steel transport and fixing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides a steel transport fixing structure, including a main beam, two sets of base support assemblies, three sets of end docking assemblies, and rope connection assemblies. The main beam is connected to the truck beam. The two sets of base support assemblies are spaced apart along the main beam. Each base support assembly includes two support frames fixed to the main beam and symmetrically arranged front to back, and a counter-connecting seat fixed between them. The two support frames centrally guide and support the steel coils, making the two steel coils symmetrical front to back and inclined, with adjacent end faces abutting against the counter-connecting seat. The three sets of end docking assemblies are staggered with the two sets of base support assemblies. Each end docking assembly includes a column rotatably mounted on the main beam, and a docking pressure plate abutting against the end face of the steel coil is provided on the column via a lifting assembly. The rope connection assembly includes a winding rope, a reinforcing rope, and a connecting rope. The winding rope is wound around the surface of the steel coil via a first guiding assembly, forming a winding section for reinforcing the steel coil and a horizontal reversing section for changing its direction. Two reinforcing ropes are symmetrically arranged left to right and connected to the upper ends of the three columns. One end of the connecting rope is connected to the horizontal reversing section of the winding rope, and the other end is connected to the reinforcing rope. Two sets of base support assemblies tilt the steel coil and abut it against the anti-collision connecting seat, forming a first-level limit. Three sets of end docking assemblies abut against the other end of the steel coil through docking pressure plates, forming a second-level limit. The rope connecting assembly forms a triple overall constraint through the winding rope wrapping, the overall connection of the reinforcing rope, and the cross-traction of the connecting ropes.

[0007] According to an advantageous embodiment, the support frame includes a base fixed to the upper side of the main beam, and four wing guards arranged in pairs on the base.

[0008] According to an advantageous embodiment, the support surface of the base is configured as a first inclined surface, and the support surface of the wing guard plate is configured as a second inclined surface. The corresponding first and second inclined surfaces together form a support guide inclined surface to control the steel coil to be centered and guided in an inclined state.

[0009] According to an advantageous embodiment, the front and rear sides of the anti-flush connecting seat and the side of the mating pressure plate that abuts against the end face of the steel coil are all provided as connecting slopes, and the connecting slopes are in contact with the corresponding inclined end face of the steel coil.

[0010] According to an advantageous embodiment, the end docking assembly further includes a locking device disposed at the bottom of the column for limiting the rotation of the column.

[0011] According to an advantageous embodiment, a turntable is fixedly provided at the bottom of the column, and the locking device is a limit pin threaded on the edge of the turntable. The upper end of the limit pin has a rotating handle, and a limit groove adapted to the limit pin is provided on the main beam at a corresponding position.

[0012] According to an advantageous embodiment, guide grooves are provided on both the front and rear sides of the column along its length. The docking pressure plate is slidably disposed in the guide groove. A through hole is provided between the two guide grooves along the length of the column. The lifting assembly includes an adjusting screw rotatably disposed in the through hole. The upper end of the adjusting screw passes through the top of the column and is fixedly connected to a wheel. A connecting seat is threaded on the adjusting screw and slidably disposed in the corresponding through hole. The connecting seat is fixedly connected to the corresponding docking pressure plate.

[0013] According to an advantageous embodiment, the first guide assembly includes a guide ring and a locking ring fixedly disposed on the left and right edges of the main beam, with both ends of the winding rope fixedly connected to the corresponding locking rings, and the winding rope passing through the guide rings to change direction.

[0014] According to an advantageous embodiment, a second guide assembly is provided on both the front and rear sides of the upper ends of the three columns. The second guide assembly includes an I-shaped guide wheel fixedly mounted on the middle column, and fixed columns are also fixedly mounted on the front and rear columns. The reinforcing rope is wound around the I-shaped guide wheel, and its two ends are respectively fixedly connected to the corresponding fixed columns.

[0015] Compared with the prior art, the steel transportation fixing structure provided by the embodiments of the present invention has the following beneficial effects: 1. In the present invention, the base support component provides initial positioning, the end docking component provides further positioning, and the rope connection component provides final reinforcement. Through rigid connection and flexible reinforcement, the shortcomings of the existing fixing method in bumpy road sections and sudden braking conditions are effectively solved, which greatly improves the safety, reliability and adaptability of steel coil transportation, while taking into account the ease of operation and meeting the transportation needs of batch steel coils.

[0016] 2. In this invention, the base support assembly forms a support guide slope through the first inclined surface of the support frame and the second inclined surface of the wing guard plate, guiding the steel coil to tilt in the center and abutting against each other through the anti-impact connecting seat, balancing the pressure and increasing friction to suppress the left and right swaying of the steel coil. The docking pressure plate of the end docking assembly forms a bidirectional abutting limit with the anti-impact connecting seat, eliminating the connection gap and avoiding the front and back displacement of the steel coil, thus solving the problems of displacement, loosening and poor adaptability caused by vibration in the traditional fixing method.

[0017] 3. In this invention, the end docking assembly and the base support assembly work together to rigidly connect all the steel coils into a whole through the anti-punch connecting seat and the docking pressure plate, which disperses the inertial impact force of the steel coils during sudden braking to prevent them from deviating and rolling off. The rope connection assembly forms multiple flexible reinforcements and further enhances the fixing effect and counteracts the influence of inertial impact force through the linkage of each rope.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will now be described in further detail.

[0026] Please refer to the following: Figure 1 and Figure 2 A steel transport fixing structure is disclosed for securing and supporting steel coils 100 during transport. The fixing structure includes a main beam 1 welded and fixed to the truck beam, two sets of base support assemblies 2, three sets of end docking assemblies 3, and rope connection assemblies 4. The two sets of base support assemblies 2 are spaced apart along the main beam 1. The three sets of end docking assemblies 3 are staggered with the two sets of base support assemblies 2. The rope connection assemblies 4 are installed between the main beam 1 and the end docking assemblies 3.

[0027] In practice, the base support assembly 2 controls the two steel coils 100 to be centered and symmetrically tilted. The two tilted steel coils 100 abut against each other through the base support assembly 2, initially limiting their position in the front-to-back and left-to-right directions. Next, the end docking assembly 3 connects the other ends of the steel coils 100, rigidly connecting them into a single unit, further limiting their position. Then, the rope connection assembly 4 connects the steel coils 100 and the two adjacent end docking assemblies 3, further limiting their position. Finally, the rope connection assembly 4 flexibly connects all the end docking assemblies 3 into a single unit, improving their stability. This triple limiting mechanism ensures the stability of the steel coils 100 under harsh road conditions and emergency braking, thereby improving the safety and reliability of steel coil transportation.

[0028] See Figure 3 and Figure 5 To reduce the risk of steel coil 100 shifting during transportation, the base support assembly 2 includes two symmetrical support frames 21 welded to the main beam 1, and a counter-connecting seat 22 welded between the two support frames 21. The side of the counter-connecting seat 22 that contacts the end face of the steel coil 100 is configured as a connecting slope. The support frame 21 includes a base fixed to the upper side of the main beam 1, and four wing guards arranged in pairs on the base. The support surface of the base is configured as a first slope 231, and the support surface of the wing guards is configured as a second slope 232. The corresponding first slope 231 and second slope 232 together form a support guide slope 23.

[0029] In operation, the inclined wing guards in the two support frames 21 guide the steel coil 100 in the center. The second inclined surface 232 of the wing guard and the first inclined surface 231 of the base form a supporting guide inclined surface 23, which allows the steel coil 100 to be centered while also tilting. The adjacent end faces of the two steel coils 100 simultaneously abut against the front and rear sides of the anti-collision connecting seat 22. The steel coil 100 is always tilted and is limited by the anti-collision connecting seat 22. In the tilted state of the two steel coils 100, part of the pressure is transferred to the front and rear sides of the anti-collision connecting seat 22, so that the pressure of the steel coils 100 on the front and rear of the anti-collision connecting seat 22 is balanced. The end face of the steel coil 100 forms friction with the anti-collision connecting seat 22, which increases the resistance when the steel coil 100 rolls in the left and right directions. At the same time, the front and rear directions are limited by the anti-collision connecting seat 22 and the end docking assembly 3.

[0030] It should be noted that the inclination angles of the first inclined surface 231 and the second inclined surface 232 are usually between 5 and 10° to avoid excessive compression of the anti-impact connecting seat 22 due to an excessively large inclination angle of the steel coil 100.

[0031] See Figure 1 , Figure 3 and Figure 4 To further improve the stability of the steel coil 100 during transportation, the end docking assembly 3 includes a column 31 rotatably mounted on the main beam 1. A docking pressure plate 33, which abuts against the end face of the steel coil 100, is provided on the column 31 via a lifting assembly 32. The side of the docking pressure plate 33 closest to the end face of the steel coil 100 is also configured as a connecting slope. A locking device 34 is provided at the bottom of the column 31.

[0032] In practice, before hoisting the steel coil 100, the column 31 is rotated 90°, the docking pressure plate 33 is moved to one side, and the height of the docking pressure plate 33 is raised by the lifting assembly 32 to make enough space, such as... Figure 6 As shown. This facilitates the lowering of the steel coil 100 to the designated position on the support frame 21 after hoisting. After the steel coil 100 is lowered and aligned with the connecting slope of the anti-collision connecting seat 22, the column 31 is rotated 90° in the opposite direction to reset, and the column 31 is limited by the locking device 34. Then, the lifting assembly 32 controls the lowering of the docking pressure plate 33 until the connecting slope of the docking pressure plate 33 is rigidly aligned with the end face of the steel coil 100. This limits the end of the steel coil 100 away from the corresponding anti-collision connecting seat 22, ensuring that all steel coils 100 are rigidly connected through the anti-collision connecting seat 22 and the docking pressure plate 33, forming a seamless whole. This significantly improves the stability of the steel coil 100 during subsequent transportation, especially in the event of vibration or sudden braking.

[0033] See Figure 3 A turntable is fixedly installed at the bottom of the column 31. The locking device 34 is a limit pin threaded onto the edge of the turntable. The upper end of the limit pin has a rotating handle. A limit groove adapted to the limit pin is opened on the main beam 1 at a corresponding position. By rotating the handle, the limit pin is controlled to move down and insert into the corresponding limit groove, so that the turntable and the column 31 cannot rotate.

[0034] See Figure 4 The column 31 has guide grooves on both its front and rear sides along its length. The docking pressure plate 33 is slidably disposed in the guide grooves. A through hole is provided between the two guide grooves along the length of the column 31. The lifting assembly 32 includes an adjusting screw 321 rotatably disposed in the through hole. The upper end of the adjusting screw 321 passes through the top of the column 31 and is fixedly connected to a wheel. A lifting slide 322 is threaded onto the adjusting screw 321 and slidably disposed in the corresponding through hole. The lifting slide 322 is fixedly connected to the corresponding docking pressure plate 33. By rotating the wheel, the operator rotates the adjusting screw 321, causing the lifting slide 322 and the docking pressure plate 33 to move up and down, thus quickly controlling the lifting of the docking pressure plate 33.

[0035] See Figures 1-3To further secure the steel coil 100, the rope connection assembly 4 includes a winding rope 41, a reinforcing rope 42, and a connecting rope 43. Each winding rope 41 is wound around the surface of the steel coil 100 via a first guide assembly 44, forming a winding section for reinforcing the steel coil 100 and a horizontal reversing section for changing the direction. Two reinforcing ropes 42 are symmetrically arranged on the left and right sides and connected to the upper ends of three columns 31. One end of the connecting rope 43 is connected to the horizontal reversing section of the winding rope 41, and the other end is connected to the reinforcing rope 42.

[0036] See Figure 1 and Figure 3 The first guide component 44 includes a guide ring 441 and a locking ring 442 fixedly disposed on the left and right edges of the main beam 1. The two ends of the winding rope 41 are fixedly connected to the corresponding locking ring 442 respectively, and the winding rope 41 passes through the guide ring 441 to change direction.

[0037] See Figure 1 and Figure 3 The three columns 31 are equipped with a second guide component 45 on both the front and rear sides of the upper end. The second guide component 45 includes an I-shaped guide wheel 451 fixedly installed on the middle column 31, and a fixing column 452 fixedly installed on the front and rear columns 31. The reinforcing rope 42 is wrapped around the I-shaped guide wheel 451, and its two ends are fixedly connected to the corresponding fixing column 452 respectively.

[0038] In practice, the winding rope 41 is wound around the surface of the steel coil 100 and works in conjunction with the first conductor assembly to wind and fix the steel coil 100. The reinforcing rope 42 is connected between the three columns 31, so that the three columns 31 interact with each other and improve the compressive strength of the columns 31. At the same time, the reinforcing rope 42 and the winding rope 41 are connected by the connecting rope 43, which also forms an interaction. When the steel coil 100 is under stress, the tension can be transmitted to the reinforcing rope 42 through the winding rope 41 and the connecting rope 43, so that the reinforcing rope 42 further tightens the columns 31 and further improves the stability of the steel coil 100.

[0039] In this solution, the overall structure adopts a triple limiting design of "rigid connection + flexible reinforcement" (base support component 2 provides initial limiting, end docking component 3 provides further limiting, and rope connection component 4 provides final reinforcement). This design solves the problem of the smooth and slippery surface of the steel coil 100 by using inclined surface contact and rigid contact, and adapts to the characteristics of the steel coil 100's large weight and high inertia by using overall force transmission. Compared with traditional rope binding and simple pad support, this design is more suitable for long-distance and complex road conditions, and completely solves the problem of insufficient adaptability of existing fixing methods.

[0040] Furthermore, although this solution adds symmetrical lifting slides 322 and end connecting components compared to the traditional steel coil 100 fixing structure, the column 31 of the end docking component 3 is rotatable and the docking pressure plate 33 is liftable. Combined with the locking device 34, it allows for quick fixing and resetting. This not only provides sufficient space for the placement of batches of steel coils 100 during hoisting but also quickly completes the limiting and fixing after the steel coils 100 are placed, solving the problems of cumbersome and inefficient fixing operations during the transportation of batches of steel coils 100. At the same time, it ensures the stability of the fixing, achieving a balance between convenience and safety. Compared to the structural cost, the additional cost is almost negligible compared to the safety of long-distance transportation of large quantities of steel coils 100.
