Description

Technical Field

[0001] This invention relates to the field of steel coil transportation technology, specifically to a steel coil transportation limiting support structure. Background Technology

[0002] Steel coil transportation is the core of the logistics link in the steel industry chain. Its main process is to transport the processed steel coils to the subsequent processing site. Since the steel coils weigh 15-30 tons, large transport vehicles are usually used for road transportation.

[0003] Currently, some manufacturers use transport vehicles with specially shaped cargo boxes for transporting steel coils. These vehicles have cargo boxes that are custom-made to fit the shape of the steel coils and are used solely for transporting them, resulting in higher overall costs. Therefore, most manufacturers adopt the following low-cost operating method: placing sleepers on the cargo box to pad the steel coils, avoiding wear and tear caused by contact between the steel coils and the cargo box. At the same time, the position of the steel coils is limited, and high-strength steel wire ropes or steel strips are used for symmetrical binding to enhance the limiting and fixing effect of the steel coils.

[0004] The following problems exist in the current steel coil transportation process: Due to the large weight of the steel coils and the fact that multiple coils are transported simultaneously in the same vehicle, the current method of simply using sleepers and steel wire ropes or steel straps for reinforcement is insufficient in limiting the movement of the steel coils. The limiting support strength is poor when subjected to external influences (such as when the transport vehicle turns or brakes, in which case the anti-tipping and limiting effects of the steel coils are inadequate), resulting in a poor overall safety factor. If the steel coils become loose, they will roll down under the influence of their own weight and inertia, puncturing the cab and causing a series of safety accidents. Furthermore, the current operation requires manual adjustment of the sleeper positions and binding of steel wire ropes multiple times according to the specifications of the steel coils, making the operation cumbersome. Summary of the Invention

[0005] Therefore, it is necessary to provide a steel coil transportation limiting support structure to solve the problems of the prior art.

[0006] This application provides a steel coil transportation limiting support structure, which is installed on the cargo box of a transport vehicle and includes:

[0007] The upper surface of the carriage panel is fixedly provided with two symmetrical fixed beams, and multiple sets of limiting components are arranged equidistantly from left to right between the two fixed beams.

[0008] The limiting component includes two sleepers symmetrically distributed on the left and right, and a support frame is provided on the opposite surface of the two sleepers. Two limiting beams are provided between the two fixed beams, located on the front and rear sides of the sleepers respectively, and the center of the limiting beams is higher than the axis of the steel coil.

[0009] The two limiting beams and the corresponding two sleepers are connected by a docking assembly, and the two limiting beams and the two sleepers form a grid-shaped frame.

[0010] A self-locking assembly is provided between the two limiting beams and the corresponding two support frames. The self-locking assembly locks the support frame in its supporting state and forms an internal triangular frame.

[0011] A locking assembly is provided between the two limiting beams and the two fixed beams. The locking assembly includes support members. Two left and right support members are hinged to the opposite sides of the two limiting beams. The support members and the limiting beams form an external triangular frame.

[0012] Before locking, a grid-shaped frame is formed around the steel coil using docking components. After locking, an inner triangular frame is formed inside the grid-shaped frame, and an outer triangular frame is formed on the front and back sides of the steel coil.

[0013] According to an advantageous embodiment, the sleeper is provided with a receiving groove, and the support frame is rotatably disposed in the receiving groove. Before placing the steel coil, a triangular pad is placed in the area between the support frame and the receiving groove.

[0014] According to an advantageous embodiment, the docking assembly includes sliding sleeves, with two symmetrical sliding sleeves slidably disposed on the opposite sides of the two sleepers in the same group, and the sleeve holes facing vertically.

[0015] The opposing surfaces of the two limiting beams are fixedly provided with plug-in posts corresponding to the sliding sleeve.

[0016] According to an advantageous embodiment, a tensioner is provided between the two opposing sliding sleeves, and the distance between the two opposing sliding sleeves is adjusted by manually adjusting the tensioner.

[0017] According to an advantageous embodiment, the opposing surfaces of the two front and rear limiting beams are each fixedly provided with an arc-shaped bonding plate by an L-shaped frame. The lower end surface of the bonding plate is an outer arc surface, and the outer arc surface of the bonding plate contacts the lower side of the inner cylinder of the steel coil.

[0018] According to an advantageous embodiment, a through rod extending longitudinally along its axis is fixedly provided on the front end face of the rear bonding plate, and a through hole corresponding to the through rod is provided through the front bonding plate longitudinally, with the rear side of the through hole being chamfered.

[0019] According to an advantageous embodiment, the self-locking assembly includes a mounting rod, the free end of the support frame is provided with a mounting rod extending forward and backward along its axis, and both the front and rear sides of the mounting rod are slidably fitted with connecting blocks, and a tensioner is provided between the connecting blocks and the limiting beam.

[0020] According to an advantageous embodiment, the locking assembly includes a connecting frame, the free end of the support member is connected to the connecting frame via a threaded rod, and the free end of the connecting frame has through-holes on both sides.

[0021] The fixed beam has a slot corresponding to the connecting frame, and a locking handle extending left and right along the axis is slidably mounted on the fixed beam. Moving the locking handle causes it to pass through the docking hole located in the slot.

[0022] According to an advantageous embodiment, the lower inner wall of the placement groove is composed of two symmetrical inclined surfaces, which slope towards the middle of the placement groove from top to bottom.

[0023] In summary, the present invention has the following beneficial effects: First, the present invention forms a grid-shaped frame around the steel coil using limiting beams and sleepers. Subsequently, the limiting beams, support frames, and sleepers are locked using self-locking components, forming multiple internal triangular frames below the steel coil. This achieves multi-dimensional locking of a single steel coil, and the stability of the locking and limiting is improved by the triangular frames and grid-shaped frames. Subsequently, multiple external triangular frames are formed between all steel coils and the fixed beams, simultaneously locking the left and right positions of each steel coil. The integrated locking, combined with the external triangular frames, improves the overall anti-overturning performance and stability of the steel coil. In summary, the multi-dimensional locking of the steel coil, from the limiting of a single steel coil to the locking of the entire vehicle's steel coils, improves the stability of the steel coil limiting and locking, and increases the safety factor during transportation.

[0024] Second, this invention uses only tensioner one and tensioner two for locking and fixing as well as locking the handle. The components are simple and the operation steps are simple. It is easy to install and lock while also being easy to disassemble. The overall process is highly convenient. Attached Figure Description

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 As shown, a steel coil transport limiting support structure is installed on the cargo box 6 of the transport vehicle, comprising:

[0036] Fixed beam 1: Two fixed beams 1 are fixedly installed on the upper end surface of the carriage panel 6, which are symmetrically arranged front and back. Multiple sets of limiting components 2 are arranged equidistantly from left to right between the two fixed beams 1.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, the limiting component 2 includes two sleepers 20 that are symmetrically distributed on the left and right and form a right triangle. The inclined surfaces of the two sleepers 20 in the same group are adjacent. Support frames 21 are provided on the opposite surfaces of the two sleepers 20. Two limiting beams 22 are provided between the two fixed beams 1, located on the front and rear sides of the sleepers 20 respectively. The center of the limiting beams 22 is higher than the axis of the steel coil.

[0038] A docking component 3 is provided between the two limiting beams 22 and the corresponding two sleepers 20, and the docking component 3 makes the two limiting beams 22 and the two sleepers 20 form a grid-shaped frame.

[0039] A self-locking assembly 4 is provided between the two limiting beams 22 and the corresponding two support frames 21. The self-locking assembly 4 not only locks the support state of the support frame 21 by the weight of the steel coil, but also forms a triangular frame in front of and behind the steel coil.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, a locking assembly 5 is provided between the two limiting beams 22 and the two fixed beams 1. The locking assembly 5 includes a support member 50. Two left and right distributed support members 50 are hinged to the opposite sides of the two limiting beams 22. By locking the free ends of the support members 50 to the limiting beams 22, an external integral triangular frame is formed.

[0041] Before locking, a grid-shaped frame is formed around the steel coil using docking component 3. After locking, an inner triangular frame is formed inside the grid-shaped frame, and an outer triangular frame is formed on the front and back sides of the steel coil.

[0042] It should be further noted that during the entire process of hoisting the steel coil into the transport vehicle, external lifting equipment or existing equipment such as forklifts (hereinafter collectively referred to as external equipment) were used to move the steel coil and cooperated with the operation throughout the limiting support process. Furthermore, the dimensions and specifications of the limiting support steel coil are all known data characteristics. The above-mentioned equipment and processes are all existing technologies, and will not be elaborated further.

[0043] During operation, firstly, based on the number of steel coils to be transported, select the corresponding number of limiting components 2 and place the sleepers 20 in the limiting components 2 opposite each other, so that the distance between two adjacent sleepers 20 is a set value. That is, at this set distance, the limiting beam 22 can dock with the corresponding sleeper 20. Then, adjust the angle of the support frame 21 so that the tilt angle of the two corresponding support frames 21 meets the corresponding steel coil placement area. After placing the steel coil at this angle, the steel coil will not contact the carriage plate 6, avoiding the problem of steel coil wear during subsequent transportation.

[0044] The steel coil is moved above the two corresponding sleepers 20 using external equipment, and gradually lowered to contact the two corresponding support frames 21. Then, the front and rear limiting beams 22 are manually installed. The limiting beams 22 are vertically connected to the adjacent sleepers 20 using the docking assembly 3. The front and rear positions of the two limiting beams 22 are manually adjusted so that the limiting beams 22 are in close contact with the steel coil. The front and rear positions of the limiting beams 22 are locked using the self-locking assembly 4 to form a grid-shaped external frame. During this process, the front and rear limiting beams 22 are docked simultaneously. At this time, the limiting beams 22 and the support frames 21 are locked by the self-locking assembly 4, so that internal triangular frames are formed on both the left and right sides of the steel coil.

[0045] After each steel coil is locked in place, the support member 50 is adjusted according to the coil's dimensions to align with the corresponding fixed beam 1 and lock it in place using the locking assembly 5. This creates two external triangular frames distributed laterally on both the front and rear sides of the steel coil. In summary, the basic grid-like frame and the internal triangular frame enhance the strength and stability of the steel coil's positioning and support. Furthermore, the external triangular frames increase the coil's resistance to overturning when subjected to forces from both sides during transport, further improving the overall strength and stability of the steel coil's positioning and support.

[0046] like Figure 3 and Figure 4 As shown, the inclined surface of the sleeper 20 is provided with a receiving groove 23, and the support frame 21 is rotatably set in the receiving groove 23. Before placing the steel coil, a triangular pad 24 is placed in the area between the support frame 21 and the receiving groove 23. The pad 24 makes the corresponding two support frames 21 form a preliminary support angle to prevent the steel coil from contacting the carriage plate 6. The contact surface between the support frame 21 and the steel coil is provided with a wooden pad (not shown in the figure). Common types of wood materials used are oak, maple or high-strength glued laminated timber.

[0047] After adjusting the position of the sleepers 20, select the corresponding size of the pads 24 according to the specifications and dimensions of the steel coil to be placed, and manually place the pads 24 between the support frame 21 and the inner wall of the receiving groove 23. The pads 24 support the support frame 21, thereby forming a preliminary V-shaped area between the two support frames 21. Then, the steel coil is hoisted and moved between the two sleepers 20. It should be noted that the method of adding pads 24 not only avoids contact and wear between the steel coil and the carriage plate 6 after placement, but also can adapt to the limiting support requirements of steel coils of different specifications and sizes. Then, the installation process of the limiting beam 22 is carried out.

[0048] like Figure 1 , Figure 3 and Figure 4As shown, the docking assembly 3 includes a sliding sleeve 30. Two symmetrical sliding sleeves 30 are provided on the back sides of the two sleepers 20 in the same group, and the holes of the sliding sleeves 30 are vertically oriented.

[0049] The opposing surfaces of the two limiting beams 22 are fixedly provided with plug-in posts 31 corresponding to the sliding sleeve 30.

[0050] like Figure 3 and Figure 4 As shown, a tensioner 32 is provided between the two opposing sliding sleeves 30, and the distance between the two opposing sliding sleeves 30 can be adjusted by manually adjusting the tensioner 32.

[0051] like Figure 4 and Figure 5 As shown, the opposing surfaces of the two front and rear limiting beams 22 are each fixedly provided with an arc-shaped bonding plate 33 by an L-shaped frame. The lower end surface of the bonding plate 33 is an outer arc surface, and the outer arc surface of the bonding plate 33 is in contact with the lower side of the inner cylinder of the steel coil.

[0052] like Figure 4 and Figure 5 As shown, a through rod 34 extending forward and backward along its axis is fixedly provided on the front end face of the rear bonding plate 33, and a through hole 35 corresponding to the through rod 34 is provided on the front bonding plate 33, with the rear side of the through hole 35 being chamfered.

[0053] The through rod 34 passes through the through hole 35, so that the front and rear limiting beams 22 form an integrated frame at the inner cylinder of the steel coil.

[0054] During operation, after the steel coil is hoisted between the two corresponding sleepers 20, the installation process of the limiting beam 22 is carried out. First, the plug-in column 31 is inserted into the corresponding sliding sleeve 30, and the bonding plate 33 is moved into the inner cylinder of the steel coil. The rear through rod 34 passes through the through hole 35 on the front bonding plate 33. At this point, the two limiting beams 22 are integrated vertically. It should be noted that the length of the L-shaped frame is a set value. With the connection of the L-shaped frame, the distance between the bonding plate 33 and the limiting beam 22 is greater than the radius of the inner cylinder of the steel coil. Therefore, when the bonding plate 33 contacts the inner cylinder of the steel coil, the limiting beam 22 is above the center of the steel coil, which improves the stability after subsequent bonding and locking. This completes the initial installation of the limiting beam 22. Then, the tensioner 32 is manually used to shorten the distance between the two adjacent sliding sleeves 30. The sliding sleeves 30 drive the limiting beam 22 to move gradually through the plug-in column 31, and finally make the limiting beam 22 tightly adhere to the steel coil.

[0055] It should be noted that during the tensioning process described above, the two sliding sleeves 30 are connected by ropes or steel belts. The tensioner 32 installed between them is an existing external device that is operated manually to bring the two sliding sleeves 30 closer together, ultimately forming a grid-shaped external frame.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, the self-locking assembly 4 includes a mounting rod 40. The free end of the support frame 21 is provided with a mounting rod 40 extending forward and backward along its axis. Both the front and rear sides of the mounting rod 40 are provided with sliding sleeves 30 and connecting blocks 41. A tensioner 42 is provided between the connecting blocks 41 and the limiting beam 22. The side of the connecting blocks 41 facing the steel coil is chamfered.

[0057] After the limiting beam 22 is installed, the connecting block 41 is manually fitted onto the corresponding mounting rod 40, and the tensioner 2 42 is manually operated to shorten the distance between the limiting beam 22 and the connecting block 41, so that the two are tightened together. At this point, an internal triangular frame composed of tensioner 2 42 (corresponding rope or steel strip), support frame 21 and limiting beam 22 is formed on both sides of the steel coil, thus completing the limiting and locking between the steel coil and the sleeper 20 (support frame 21).

[0058] Regarding the force situation during the locking process, it should be further explained that since the bonding plate 33 is in contact with the inner cylinder of the steel coil, when the tensioner 22 is tightened, the limiting beam 22 cannot continue to move down. Therefore, the corresponding support frame 21 is integrated and locked with the steel coil. In addition, the weight of the steel coil itself acts on the support frame 21, which is then transmitted to the pad 24 and sleeper 20 through the support frame 21, and to the limiting beam 22 through the tensioner 22. This causes friction between the sleeper 20 and the carriage plate 6. Therefore, the sleeper 20, support frame 21, and limiting beam 22 are all in a fixed state, forming a support and locking state for the steel coil.

[0059] like Figure 1 , Figure 6 and Figure 7 As shown, the locking assembly 5 includes a connecting frame 51, and the free end of the support member 50 is connected to the connecting frame 51 through a threaded rod. The free end of the connecting frame 51 has mating holes 52 extending through it on the left and right sides.

[0060] The fixed beam 1 has a placement groove 53 corresponding to the connecting frame 51. A locking handle 54 with an axis extending left and right is slidably provided on the fixed beam 1. Moving the locking handle 54 causes the locking handle 54 to pass through the docking hole 52 located in the placement groove 53.

[0061] like Figure 6 and Figure 7As shown, the side of the docking hole 52 that contacts the locking handle 54 is chamfered, and the lower inner wall of the placement groove 53 is composed of two symmetrical inclined surfaces, which slope towards the middle of the placement groove 53 from top to bottom.

[0062] After the support and locking of a single steel coil is completed, the distance between the connecting frame 51 and the support member 50 is adjusted by manually rotating the threaded rod, and the angle of the support member 50 is adjusted. Finally, the free end of the connecting frame 51 is placed into the placement groove 53. The two inclined surfaces in the placement groove 53 facilitate the insertion of the semi-circular section at the tail end of the connecting frame 51, improving the ease of installation. Secondly, the connecting frame 51 is in a downward inclined state, and the two inclined surfaces provide support for the support member 50 and the limiting beam 22.

[0063] Afterwards, the locking handle 54 is manually moved so that it passes through the docking hole 52, locking the connecting frame 51 and the support 50. At this point, all the limiting beams 22, the support 50, the connecting frame 51 and the fixed beam 1 together form multiple external triangular frames located on the front and rear sides of the corresponding steel coils. Combined with the feature that the limiting beam 22 is higher than the center of the steel coil, the anti-overturning performance of the steel coil is improved during transportation. Secondly, it indirectly locks the steel coil, the limiting beam 22 and the sleeper 20. The overall stability is improved through integrated locking, inner and outer triangular frames and grid-shaped frames. In addition, the external triangular frame of each steel coil is made separately, which makes it easy to adapt to the limiting locking process of steel coils of different specifications in the same vehicle, improving the convenience and applicability of the device. Secondly, it should be noted that the disassembly process requires manual operation of tensioner 1 32 and tensioner 2 42 to release the tension, which releases the limiting lock on the steel coil, and then the steel coil can be disassembled.

[0064] Furthermore, for the components used in this technical solution, such as the fixed beam 1, support frame 21, limiting beam 22, support member 50, and connecting frame 51, which are used to construct the internal and external triangular frames, structural steel (common types include Q235B and Q355B) can be used. After forming the triangular frame, the overall strength can meet the limiting support requirements during the transportation of the steel coil. Secondly, the tensioner 1 32 and tensioner 2 42 involved can be lever-type tensioners, ratchet-type tensioners, and bolt push-pull-type tensioners, etc. After being tensioned manually, they can provide the tension force and vibration resistance to meet the requirements of locking the heavy weight of the steel coil.

[0065] Regarding the overall operation process, additional explanation is needed. In existing technologies, triangular or rectangular sleepers 20 are placed on the carriage panel 6 as the foundation for placing the steel coil, and external steel cables are used for locking to complete the limiting and supporting steps for the steel coil. Alternatively, a custom-shaped carriage panel 6 is used as the supporting foundation. Compared to existing technologies, this technical solution adds a fixing beam 1, a limiting component 2, a support frame 21, a limiting beam 22, a docking component 3, a self-locking component 4, and a locking component 5. First, a grid-like frame is formed around the steel coil using the limiting beam 22 and the sleepers 20. Subsequently, the self-locking component 4 locks the limiting beam 22, the support frame 21, and the sleepers 20, forming multiple internal triangular frames below the steel coil. This completes the locking process for a single steel coil. Finally, the locking component 5 ensures that all steel coils form multiple external triangular frames with the fixed beam 1. In summary, the overall stability and anti-overturning performance are improved by using a grid-shaped frame, inner and outer triangular frames, and integrated locking of all steel coils. The components are simple and easy to operate. Compared with the existing technical solution of customized shaped carriage panels 6, this solution has a lower cost. Furthermore, the added components are all external conventional mechanical parts, and can be used for a long time after a one-time investment. Compared with the improved limiting and support effect on the steel coils, the cost of the added components is negligible. Therefore, this technical solution is a specific improvement made entirely based on and to solve the defects of the existing technology.
