Description

Technical Field

[0001] This utility model relates to the field of steel transportation technology, and in particular to a steel coil limiting stake structure for a steel transportation vehicle. Background Technology

[0002] Steel coil limit stakes are key safety components used in logistics transportation to fix steel coils and prevent displacement. Essentially, they restrict the rolling or movement of steel coils during transportation by physically blocking them, thus preventing collisions, falls, and safety accidents or cargo damage.

[0003] Chinese Patent Publication No. CN211543373U discloses a steel coil limiting stake structure for a steel transport vehicle. The structure includes limiting stakes located near both ends of the steel coil on the vehicle body and limiting the length of the steel coil at both ends. During vehicle movement or turning, the limiting stakes can hold the ends of the steel coil in place to prevent the steel coil from moving and causing an accident.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: First, there is the problem of incomplete limiting. Some can only limit the two ends of the steel coil in the length direction, and the limiting of the sides and circumference is insufficient. In addition, vibration during transportation can also cause the steel coil to move, which will cause the fixation on both sides to loosen, and ultimately lead to the steel coil being unstable or even falling. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to fully limit the position of steel coils. To this end, we propose a steel coil limiting stake structure for logistics steel transport vehicles.

[0006] To achieve the above objectives, this application adopts the following technical solution: a steel coil limiting stake structure for a steel transport vehicle, comprising: a vehicle plate, and a fixing frame disposed on the upper surface of the vehicle plate, wherein a stepped limiting block is fixedly installed on the inner wall of the fixing frame, the steel coil is located inside the fixing frame, and fixing components are provided on both sides of the fixing frame, and both sets of fixing components are fixed to the upper surface of the vehicle plate by bolts.

[0007] The fixing assembly includes a fixing plate fixedly installed on the upper surface of the vehicle body, and a fixing post fixedly installed on the upper surface of the fixing plate. The fixing post has a screw threadedly connected inside, and a pad is fixedly installed at one end of the screw. A pressure plate is slidably connected inside the fixing post. The bottom of the pressure plate contacts the upper part of the outer surface of the steel coil. A blocking plate is slidably connected inside the pressure plate. One side of the pad contacts one side of the blocking plate. Extension plates are provided on both sides of the blocking plate. One side of the blocking plate and the two sets of extension plates contacts the outer surface of the steel coil. L-shaped plates are slidably connected inside the two sets of extension plates. One side of each set of L-shaped plates contacts the outer surface of the steel coil. Fixing rods are hinged inside the L-shaped plates and on the outer surface of the pressure plate to limit and fix the steel coil in multiple directions.

[0008] The other set of fixing components has fitting grooves on the inside of the L-shaped plate and the outer surface of the pressure plate. The fixing rods are fitted into the corresponding fitting grooves to ensure the stability of the connection.

[0009] Preferably, a buffer layer is provided on one side of the stepped limiting block. The buffer layer is a component made of rubber to prevent damage to the steel coil.

[0010] Preferably, one side of each set of pressure plates, blocking plates, extension plates and L-shaped plates is provided with a wear-resistant and anti-slip layer. The wear-resistant and anti-slip layer is a component made of polyurethane, which extends its service life.

[0011] Preferably, each set of fixed columns is provided with a slide rail inside, and a slider is sleeved on the outer surface of the slide rail. One side of the slider is fixed to one side of the pressure plate to prevent displacement or jamming during movement.

[0012] Preferably, each pressure plate has a movable groove A inside, a movable block A is slidably connected inside the movable groove A, the bottom of the movable block A is fixedly connected to one side of the corresponding blocking plate, and a limit plate A is provided on the upper surface of the movable block A to prevent the blocking plate from sliding out of the movable groove A.

One side of the movable block B is fixedly connected to one side of the corresponding L-shaped plate, and a limit plate B is provided on the other side of the movable block B to prevent the L-shaped plate from sliding out of the movable groove B.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the device first hoists the steel coil into the fixing frame and initially limits it with a stepped limiting block. The pressure plate is then moved down to the position of contacting the upper surface of the steel coil. Next, the blocking plate and the extension plates on both sides are moved together to the outer surface of the steel coil. Then, by rotating the screw, the pad is moved to the position where the blocking plate fits, and the blocking plate is fixed firmly. Therefore, the blocking plate and the extension plates can be stably fitted to the outer surface of the steel coil. Finally, the fixing rod is used to fit into the fitting groove to further fix the fixing components on both sides, thereby limiting and fixing the steel coil in multiple directions, so that the steel coil can be more stably fixed inside the steel transport vehicle.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a steel coil limiting stake structure for a steel transport vehicle, including: a vehicle plate 1, and a fixing frame 2 set on the upper surface of the vehicle plate 1. A stepped limiting block 3 is fixedly installed on the inner wall of the fixing frame 2. The steel coil 4 is located inside the fixing frame 2. Fixing components 5 are provided on both sides of the fixing frame 2. Both sets of fixing components 5 are fixed to the upper surface of the vehicle plate 1 by bolts. The steel coil 4 is hoisted in the fixing frame 2 and is initially limited by the stepped limiting block 3.

[0024] Reference Figures 1-4As shown in this embodiment: the fixing component 5 includes a fixing plate 51 fixedly installed on the upper surface of the vehicle plate 1, and a fixing post 52 fixedly installed on the upper surface of the fixing plate 51. A screw 53 is threadedly connected inside the fixing post 52, and a pad 531 is fixedly installed at one end of the screw 53. A pressure plate 54 is slidably connected inside the fixing post 52, and the bottom of the pressure plate 54 contacts the upper part of the outer surface of the steel coil 4. A blocking plate 55 is slidably connected inside the pressure plate 54, and one side of the pad 531 contacts one side of the blocking plate 55. Extension plates 56 are provided on both sides of the blocking plate 55, and one side of both the blocking plate 55 and the two sets of extension plates 56 contacts the outer surface of the steel coil 4. The interiors of the two sets of extension plates 56 are slidably connected... An L-shaped plate 57 is attached, with one side of each L-shaped plate 57 contacting the outer surface of the steel coil 4. Fixing rods 58 are hinged to the inside of the L-shaped plate 57 and the outer surface of the pressure plate 54. The pressure plate 54 is moved down to the position of contacting the upper surface of the steel coil 4. Then, the blocking plate 55 and the extension plates 56 on both sides are moved together to the outer surface of the steel coil 4. Then, by rotating the screw 53, the pad 531 is moved to the position where the blocking plate 55 is attached, and the blocking plate 55 is fixed firmly. Therefore, the blocking plate 55 and the extension plates 56 can be stably attached to the outer surface of the steel coil 4. Finally, the fixing rods 58 are used to engage with the fitting grooves 59 to further fix the fixing components 5 on both sides, thereby limiting and fixing the steel coil 4 in multiple directions.

[0025] The other set of fixing components 5, which is opposite to the current fixing component 5, has fitting grooves 59 on the inside of the corresponding L-shaped plate 57 and the outer surface of the pressure plate 54. The two ends of the fixing rod 58 are respectively fitted and connected to the fitting grooves 59 of the two sets of fixing components 5 to ensure the stability of the connection.

[0026] A buffer layer is provided on one side of the stepped limiting block 3. The buffer layer is a component made of rubber, which can not only buffer the impact when the steel coil 4 is hoisted and placed to prevent damage to the steel coil 4, but also play a role in initially limiting the position of the steel coil 4.

[0027] Each set of pressure plate 54, blocking plate 55, extension plate 56 and L-shaped plate 57 has a wear-resistant and anti-slip layer on one side. The wear-resistant and anti-slip layer is a component made of polyurethane, which makes the steel coil 4 more stable and less prone to slipping when it is fixed, while improving its wear resistance and extending its service life.

[0028] Each set of fixed columns 52 is equipped with a slide rail 521 inside. The outer surface of the slide rail 521 is fitted with a slider 522. One side of the slider 522 is fixed to one side of the pressure plate 54 to prevent displacement or jamming during movement. The pressure plate 54 can restrict the movement of the steel coil 4 from above.

[0029] Each pressure plate 54 has a movable groove A541 inside. A movable block A542 is slidably connected inside the movable groove A541. The bottom of the movable block A542 is fixedly connected to one side of the corresponding blocking plate 55. A limit plate A543 is provided on the upper surface of the movable block A542. The cross-section of the movable block A542 is wedge-shaped. The inner wall of the corresponding movable groove A541 is provided with a matching inclined surface. When the blocking plate 55 is subjected to the reaction force of the steel coil 4, the wedge structure will generate a lateral component force, so that the movable block and the inclined surface of the movable groove are tightly fitted, and self-locking is achieved by friction. The size of the limit plate A543 must be larger than the opening size of the movable groove A541, so as to prevent the blocking plate 55 from sliding out of the movable groove A541.

[0030] Each set of extension plates 56 has a movable groove B561 inside. A movable block B562 is slidably connected inside the movable groove B561. One side of the movable block B562 is fixedly connected to one side of the corresponding L-shaped plate 57. A limit plate B563 is provided on the other side of the movable block B562. The cross-section of the movable block B562 is wedge-shaped. The inner wall of the corresponding movable groove B561 is provided with a matching inclined surface. This mating structure can therefore be self-locking. The size of the limit plate B563 must be larger than the opening size of the movable groove B561 to prevent the L-shaped plate 57 from sliding out of the movable groove B561.

[0031] Working principle: The steel coil 4 to be transported is hoisted into the fixed frame 2 on the upper surface of the vehicle platform 1, so that the bottom of the steel coil 4 contacts the stepped limiting block 3 on the inner wall of the fixed frame 2, thereby initially limiting it and preventing the steel coil 4 from shifting in a large range in the horizontal direction. In addition, the rubber buffer layer on one side of the stepped limiting block 3 can also buffer the impact force when the steel coil 4 is hoisted and placed, avoiding damage to the outer surface of the steel coil 4 due to rigid contact. At the same time, the friction of the rubber further enhances the initial limiting effect. Then, the pressure plate 54 is moved down to contact the upper surface of the steel coil 4. The cooperation between the slide rail 521 and the slider 522 prevents the pressure plate 54 from shifting or jamming during movement, ensuring that the pressure plate 54 accurately fits the upper part of the steel coil 4. Next, the blocking plate 55 is pushed, causing the bottom moving block A542 to slide along the moving groove A541 inside the pressure plate 54 until the wear-resistant and anti-slip layer on one side of the blocking plate 55 is in contact with the outer surface of the steel coil 4. At the same time, the extension plates 56 on both sides of the blocking plate 55 are adjusted so that one side of the extension plate 56 also contacts the outer surface of the steel coil 4, expanding the lateral limiting range of the steel coil 4. Then, the screw 53 inside the fixing column 52 is rotated, causing the pad 531 at one end of the screw 53 to move towards the resistance. The baffle 55 moves in the direction until the pad 531 is tightly fitted with the baffle 55. The position of the baffle 55 and the extension plate 56 is fixed by the clamping force of the pad 531. In addition, the cross section of the moving block A542 is wedge-shaped, and the inner wall of the moving groove A541 is provided with a matching inclined surface. Therefore, when the baffle 55 is subjected to the reaction force of the steel coil 4, the wedge structure will generate a lateral component force, so that the moving block A542 and the inclined surface of the moving groove A541 are tightly fitted, and self-locking is achieved by friction, preventing the baffle 55 from loosening. In addition, the size of the limiting plate A543 is larger than the opening size of the moving groove A541, which can prevent the baffle 55 from sliding out of the moving groove A541 and ensure the stability of the structure. Pull the L-shaped plate 57 again, causing the moving block B562 on one side to slide along the moving groove B561 inside the extension plate 56 until the wear-resistant and anti-slip layer on one side of the L-shaped plate 57 is in contact with the outer surface of the steel coil 4, thus completing the further lateral limitation of the steel coil 4. Finally, rotate the fixing rod 58 that is hinged between the inside of the L-shaped plate 57 and the outer surface of the pressure plate 54, so that one end of the fixing rod 58 is embedded in the corresponding fitting groove 59 of another set of fixing components 5, thus completing the linkage fixation of the two sets of fixing components 5, realizing the multi-directional limitation and fixation of the steel coil 4, and ensuring the stability of the steel coil 4 during transportation.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
