Description

Technical Field

[0001] This utility model relates to the field of automobile transportation technology, specifically a tire tie-down device for automobile transportation. Background Technology

[0002] In scenarios involving roll-on / roll-off (Ro-Ro) transport of automobiles or railcarrying, it is essential to reliably secure vehicle tires to the transport vehicle (such as a freight car deck, railcar flatcar, or Ro-Ro ship deck) to prevent lateral slippage, longitudinal movement, or rotation around the vertical axis during bumpy, braking, or turning conditions. This avoids safety hazards caused by vehicle collisions, paint damage, and center of gravity shift. Therefore, the industry commonly employs tire restraint devices to implement multi-point, multi-directional restraint on automobile tires to maintain vehicle stability throughout the transportation process.

[0003] Existing technologies typically employ a "carrying plate + ratchet strap" or "ring-shaped positioning frame + clamping strap" structure: the carrying plate is fixed to the transport vehicle, the strap wraps around the tire and is tightened by a ratchet mechanism, or a rigid positioning frame is placed above the tire to achieve axial restraint. However, the above solutions have the following drawbacks: 1. The tire needs to be manually lifted or pushed laterally into the positioning frame, which limits the operating space and increases labor intensity; 2. The positioning frame or strap only provides radial or axial unidirectional restraint, and the tire may still rotate slightly in the circumferential direction, leading to tread wear; 3. When the tire specifications change, a positioning frame of a different size or the strap length needs to be readjusted, resulting in poor versatility; 4. Existing carrying plates are mostly fixed rigid structures, which cannot provide adjustable lateral restraint for the tire, and are prone to lateral displacement when the vehicle tilts.

[0004] To address the aforementioned issues, this application provides a tire lashing device for automobile transportation. Utility Model Content

[0005] The purpose of this utility model is to provide a tire binding device for automobile transportation in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A tire binding device for automobile transport includes a support plate, a wheel circumference limiting mechanism, a wheel side limiting mechanism, and a binding mechanism, wherein: The support plate is arranged horizontally; The number of wheel circumference limiting mechanisms is two, and they are respectively arranged on both ends of the support plate. The wheel circumference limiting mechanisms are used to guide the car tires onto the support plate and to limit the rolling direction of the tires. The wheel-side limiting mechanism is installed on one side of the top of the bearing plate and is used to limit the side of the tire. The binding mechanism is mounted on the support plate and is used to bind the tires.

[0007] Furthermore, the wheel circumference limiting mechanism includes a guide limiting plate with one end hinged to one end of the bearing plate, and the other end of the guide limiting plate can be rotated to be flush with the bottom side of the bearing plate. The wheel circumference limiting mechanism also includes a fixing member for unidirectionally fixing the guide limiting plate.

[0008] Furthermore, the fixing component includes a drive gear, a transmission gear, a ratchet, and a locking pin. A horizontal mounting rod is rotatably mounted on one side of the bearing plate. The drive gear and the ratchet are both fixedly sleeved on the mounting rod. The transmission gear is fixedly sleeved on one end of the guide limiting plate shaft and meshes with the drive gear. The locking pin is rotatably mounted on the bearing plate and one end is movably inserted between two adjacent teeth of the ratchet.

[0009] Furthermore, a connecting plate is fixed on the support plate, and a spring is connected between the connecting plate and the locking pin.

[0010] Furthermore, the wheel-side limiting mechanism includes a baffle fixed to one side of the top of the bearing plate.

[0011] Furthermore, the binding mechanism includes a device block and a fixing block mounted on the support plate. The fixing block has a vertical through-groove. The binding mechanism also includes a binding rope. One end of the binding rope is fixed to the device block, and the other end of the binding rope movably passes through the through-groove. The fixing block is equipped with a limiting member for fixing the binding rope.

[0012] Furthermore, the internal structure of the fixing block has an installation groove communicating with the through groove. The limiting member includes a movable plate movably disposed inside the installation groove. A limiting pin is fixed on one side of the movable plate, and a control rod with its end movably extending to the outside of the fixing block is fixed on the other side of the movable plate. A spring two sleeved on the control rod is connected between the other side of the movable plate and the inner wall of the installation groove. A plurality of limiting grooves arranged in an array are constructed through the binding rope. The end of the limiting pin facing away from the movable plate is movably inserted into the interior of one of the limiting grooves.

[0013] Furthermore, the top side of the limiting pin facing away from the movable plate is constructed as an inclined surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This application features flip-up guide plates at both ends of the support plate. When a tire drives in, the guide plates are unfolded and flush with the bottom of the support plate, forming a smooth transition slope. The tire can roll in directly without being lifted. After driving in, the guide plates are quickly erected and automatically kept vertical by a one-way locking mechanism consisting of a drive gear, a transmission gear, a ratchet, and a locking pin. This achieves instantaneous limitation of the tire's forward and backward rolling directions. Compared with existing methods such as "side-push into the positioning frame" or "lifting the tire into the ring frame", this significantly reduces the operating space requirements and labor intensity.

[0015] The baffle fixed on the top side of the bearing plate in this solution constitutes the first lateral limit for the tire; the guide limiting plates that can be locked in a vertical state at both ends constitute the second and third limits for the tire rolling direction; the binding rope passes through the groove of the fixing block and is quickly locked by the limiting component to form radial compression. The baffle, guide limiting plate and binding rope together constitute a three-dimensional constraint in the front-rear-side direction, which completely eliminates the circumferential micro-rotation space of the tire and avoids tire tread wear.

[0016] In this solution, the rotation angle of the guide limiting plate is continuously adjustable by a gear-ratchet mechanism, which is compatible with tires of different diameters. The binding rope slides along the groove and is continuously positioned by cooperating with the limiting pin through the array limiting groove, which can quickly match different tire cross-section widths. Therefore, when the tire specifications change, there is no need to replace the positioning frame or repeatedly cut the binding strap length, which significantly improves versatility.

[0017] In this solution, the baffle is fixed to the top side of the bearing plate, providing rigid lateral support; after the guide limiting plate is vertically locked, its inner side forms a line contact limit with the tire tread; the binding rope is radially tightened to keep the tire in close contact with the baffle and the guide limiting plate. The triple lateral constraint works together to effectively suppress the lateral displacement of the tire even if the vehicle tilts during transportation. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] This application provides a tire binding device for automobile transport. Existing technologies typically employ a structure of "carrier plate + ratchet binding strap" or "ring-shaped positioning frame + clamping strap": the carrier plate is fixed to the transport vehicle, the binding strap wraps around the tire and is tightened by a ratchet mechanism, or a rigid positioning frame is placed above the tire to achieve axial restraint. However, the above solutions have the following drawbacks: 1. The tire needs to be manually lifted or pushed laterally into the positioning frame, resulting in limited operating space and high labor intensity; 2. The positioning frame or binding strap only provides radial or axial unidirectional restraint, and the tire may still rotate slightly circumferentially, leading to tread wear; 3. When tire specifications change, different sized positioning frames or readjusted binding strap lengths are required, resulting in poor versatility; 4. Existing carrier plates are mostly fixed rigid structures, unable to provide adjustable lateral restraint for the tire, easily causing lateral displacement when the vehicle tilts. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation: A tire binding device for automobile transport mainly includes a support plate 1, a wheel circumference limiting mechanism 2, a wheel side limiting mechanism 3, and a binding mechanism 4, wherein: The load-bearing plate 1 is horizontally fixed to the deck of the transport vehicle, forming the base of the entire lashing device; There are two wheel circumference limiting mechanisms 2, which are respectively set on both ends of the support plate 1. The wheel circumference limiting mechanism 2 is used to guide the car tire into the support plate 1 and to limit the rolling direction of the tire. The wheel side limiting mechanism 3 is installed on one side of the top of the bearing plate 1 and is used to limit the side of the tire; The binding mechanism 4 is mounted on the support plate 1 and is used to bind the tires.

[0022] This solution effectively ensures the stability of the vehicle during transportation through triple limiting mechanisms: the wheel circumference limiting mechanism 2, the wheel side limiting mechanism 3, and the binding mechanism 4.

[0023] For details, please refer to Figure 2 , Figure 4 and Figure 5 The wheel circumference limiting mechanism 2 includes a guide limiting plate 21 with one end hinged to one end of the support plate 1. The other end of the guide limiting plate 21 can be rotated to be flush with the bottom side of the support plate 1. The guide limiting plate 21 is rotated downward with the hinge point at the end of the support plate 1 as the axis until its free end is flush with the bottom side of the support plate 1, forming a smooth slope for the tire to roll into. The wheel circumference limiting mechanism 2 also includes a fixing member 22 for unidirectional fixing of the guide limiting plate 21. When the tire is completely driven into the support plate 1, the two guide limiting plates 21 are rotated to contact the circumference of the tire and fixed by the fixing member 22, which can limit the tire. Furthermore, the fixing component 22 includes a drive gear 221, a transmission gear 222, a ratchet 223, and a locking pin 224. A horizontal mounting rod 11 is rotatably mounted on one side of the support plate 1. The drive gear 221 and the ratchet 223 are both fixedly sleeved on the mounting rod 11. The transmission gear 222 is fixedly sleeved on one end of the guide limiting plate 21's rotating shaft and meshes with the drive gear 221. The locking pin 224 is rotatably mounted on the support plate 1, and one end is movably inserted between two adjacent teeth of the ratchet 223. A connecting plate 12 is fixed on the support plate 1, and a spring 13 connects the connecting plate 12 and the locking pin 224. Figure 1 and Figure 4 For the view, when the car tire drives onto the carrier plate 1, the guide limiting plate 21 is manually rotated, and the transmission gear 222 on its rotating shaft rotates synchronously. The drive gear 221 meshing with it drives the ratchet 223 to rotate. At this time, the locking pin 224 will not block the rotation of the ratchet 223. When the guide limiting plate 21 reaches the predetermined position, the locking pin 224 is instantly sprung into the adjacent teeth of the ratchet 223 under the combined action of the connecting plate 12 and the spring 13, forming a one-way mechanical lock, preventing the ratchet 223 from rotating in the opposite direction, thereby keeping the guide limiting plate 21 in the predetermined state, continuously providing rigid limit for the front and rear rolling of the tire, and preventing the plate from flipping back or the tire from moving longitudinally due to bumps during transportation. When the vehicle tire is engaged, pressing one end of the locking pin 224 disengages the other end of the locking pin 224 from the ratchet 223, allowing the guide limiting plate 21 to rotate until its free end is flush with the bottom side of the support plate 1, facilitating the vehicle's departure.

[0024] In this embodiment, please refer to Figure 2The wheel side limiting mechanism 3 includes a baffle 31 fixed on one side of the top of the support plate 1. When the tire rolls into the support plate 1, the tire sidewall approaches the inner surface of the baffle 31, immediately forming a stable lateral support. Since the movable gap between the baffle 31 and the support plate 1 is very small, the lateral inertial force generated by the vehicle during transportation is directly transmitted to the support plate 1 and the transport vehicle by the baffle 31, thereby preventing the tire from sliding or tilting relative to the support plate 1. This ensures that the lateral constraint in the three-way limiting system is always in a rigid locked state, and can be adapted to tires of different widths without additional adjustment, simplifying the structure and improving universal reliability.

[0025] It should be noted that you should refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 The binding mechanism 4 includes a device block 41 and a fixing block 42 mounted on the support plate 1. The fixing block 42 has a vertical through groove 43. The binding mechanism 4 also includes a binding rope 44. One end of the binding rope 44 is fixed to the device block 41, and the other end of the binding rope 44 moves through the through groove 43. The fixing block 42 is equipped with a limiting member 45 for fixing the binding rope 44. When the car tire drives into the support plate 1 and is limited by the wheel circumference limiting mechanism 2, the free end of the binding rope 44 is pulled to wrap around the upper surface of the tire, then passes through the through groove 43 and is fixed by the limiting member 45, which can limit the tire. Furthermore, please refer to Figure 2 , Figure 3 and Figure 4 The internal structure of the fixing block 42 has an installation groove 46 that communicates with the through groove 43. The limiting member 45 includes a movable plate 451 that is movably disposed inside the installation groove 46. A limiting pin 452 is fixed on one side of the movable plate 451, and a control rod 453 with its end movably extending to the outside of the fixing block 42 is fixed on the other side of the movable plate 451. A spring 454 sleeved on the control rod 453 is connected between the other side of the movable plate 451 and the inner wall of the installation groove 46. A number of limiting grooves 441 arranged in an array are constructed through the binding rope 44. The end of the limiting pin 452 facing away from the movable plate 451 is movably inserted into the inside of one of the limiting grooves 441. By inserting the limiting pin 452 into the inside of one of the limiting grooves 441, the binding rope 44 can be fixed to the outer periphery of the tire. The top side of the limiting pin 452 facing away from the movable plate 451 is sloped. The slope facilitates quick installation. When binding the tire, one end of the binding rope 44 passes through the slot 43 and the binding rope 44 is pulled to move it. The side wall of the limiting slot 441 abuts against the slope of the limiting pin 452, which can drive the limiting pin 452 to move into the mounting slot 46. Under the elastic force of the second spring 454, it is locked into the next limiting slot 441, but it cannot be pulled in the opposite direction. When it contacts the binding rope 44, the control rod 453 is manually pulled to retract the limiting pin 452 into the mounting slot 46, so that one end of the binding rope 44 is released from the slot 43 and the binding of the tire is released.

[0026] When the device is in use, the bearing plate 1 is first fixed horizontally to the deck of the transport vehicle; the guide limiting plates 21 at both ends hang down naturally to be flush with the bottom side of the bearing plate 1 when the spring 13 and the locking pin 224 are released, forming a continuous and smooth slope. The vehicle tire rolls directly into the bearing plate 1 along the slope until the tire sidewall abuts against the baffle 31, completing the initial lateral positioning. Subsequently, manually pull the guide limit plate 21 upward, the transmission gear 222 rotates and drives the drive gear 221 and the coaxial ratchet 223 to rotate. The locking pin 224 briefly retracts under the pressure of the back of the teeth. When the plate reaches the vertical limit position, the locking pin 224 is instantly engaged between the teeth of the ratchet 223 under the action of the spring 13, realizing one-way mechanical locking. The guide limit plate 21 remains vertical and forms a rigid constraint on the front and rear rolling direction of the tire. Then, the free end of the binding rope 44 is passed around the upper surface of the tire and inserted into the groove 43 of the fixing block 42. During the outward tightening process, the limiting groove 441 slides past the inclined surface of the limiting pin 452 in sequence and forces it to retract into the mounting groove 46. After each limiting groove 441 is passed, the spring 454 immediately pushes the limiting pin 452 to automatically engage with the next limiting groove 441, forming a one-way self-locking that tightens as it is pulled, until the binding rope 44 is close to the outer circumference of the tire, completing the radial compression. During unloading, first press the locking pin 224 to release the ratchet 223 from locking, so that the guide limit plate 21 is reset to the slope state; Pull the control lever 453 again, the limit pin 452 retracts, and the binding rope 44 can be pulled out from the slot 43. The tire drives away smoothly along the slope. The entire loading and unloading process requires no additional tools and is quick and safe.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
