Description

Technical Field

[0001] This invention belongs to the technical field of steel coil fixing frames, specifically a steel coil transport fixing frame. Background Technology

[0002] A steel coil transport securing frame is a specialized piece of equipment used for transporting steel coils to ensure their stability during transport. Steel coils are prone to shifting and sliding during transport, especially on uneven roads, during sudden braking, or when turning. The transport securing frame, through its fixing and supporting devices, ensures the stability of the steel coils during transport, thus preventing accidents. Transport securing frames are widely used for transporting different types of steel coils, such as cold-rolled steel coils, galvanized coils, and color-coated coils, demonstrating high versatility. By fixing and supporting the steel coils, the transport securing frame ensures safety during transport, reducing cargo damage and truck rollover accidents. The steel coil transport securing frame plays a unique role and offers significant advantages in steel coil transport, making it an indispensable piece of equipment in the logistics industry. However, existing steel coil transport securing frames cannot be adapted to the diameter of the steel coils, making it impossible to stably place steel coils of different sizes. Furthermore, pressure buildup and external damage can occur between the steel coils and the securing frame, affecting the later use of the steel coils. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a steel coil transport fixing frame, which effectively solves the problem that the existing steel coil transport fixing frame cannot be adaptively adjusted according to the diameter of the steel coil, thus making it impossible to stably place steel coils of different sizes, and causing pressure damage between the steel coil and the fixing frame.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel coil transport fixing frame, comprising a base plate, movable plates inserted into both sides of the base plate, support frames fixedly installed on the upper sides of the two movable plates, crossbeams fixedly installed on the sides of the two support frames that are close to each other, two connecting frames fixedly installed on the upper sides of the two crossbeams, rollers rotatably installed on the top of the four connecting frames, rotating frames fixedly installed at both ends of the inner top of the two support frames, and a coil rotatably installed on one side of the rotating frame, with two lifting straps wound between the four coils.

Several anti-slip strips for preventing sliding displacement are fixedly installed on the bottom of the base plate. A transmission assembly is provided at the output end of the drive motor. The transmission assembly is connected to the two movable plates and the four coils. When the drive motor is running, it outputs power to the two movable plates and the four coils through the transmission assembly, causing the two movable plates to move in opposite directions and the four coils to unwind the two lifting straps.

[0005] Preferably, the inner walls at both ends of the base plate are provided with sliding grooves, and the two ends of the two movable plates are fixedly installed with sliding strips, with the four sliding strips slidably installed inside the two sliding grooves respectively.

[0006] Preferably, the transmission assembly includes a lower gear, a rotating seat is rotatably mounted on one side of the lower gear, the bottom of the rotating seat is fixedly connected to the inner bottom of the base plate, an upper gear is meshed with the upper part of the lower gear, a shaft is fixedly mounted in the middle of the upper gear, and four bushings are rotatably mounted at equal intervals on the surface of the shaft, the bottom of each of the four bushings is fixedly connected to the inner bottom of the base plate.

[0007] Preferably, a first worm gear is fixedly installed in the middle of the shaft, and a second worm gear is fixedly installed at both ends of the shaft. A positioning seat is rotatably installed at the ends of the two second worm gears that are far apart from each other, and the bottom of the two positioning seats is fixedly connected to the inner bottom of the base plate.

[0008] Preferably, the lower parts of the two second worm gear surfaces are meshed with second worm wheels, the middle parts of the two second worm wheels are fixedly mounted with rotating shafts, the two ends of the two rotating shaft surfaces are rotatably mounted with bearings, and the bottoms of the four bearings are fixedly connected to the inner bottom of the base plate.

[0009] Preferably, threaded rods are fixedly installed at both ends of the two rotating shafts, and threaded sleeves are threadedly connected to the surfaces of the four threaded rods. The four threaded sleeves are respectively fixedly installed inside the two moving plates.

[0010] Preferably, a first worm gear is meshed with the lower part of the surface of the first worm, and rotating tubes are fixedly installed on both sides of the first worm gear. Rotating sleeves are rotatably installed at the ends of the two rotating tubes that are close to each other. The bottoms of the two rotating sleeves are fixedly connected to the inner bottom of the base plate. Rectangular rods are movably inserted into the interior of the two rotating tubes. Transmission rods are fixedly installed at the ends of the two rectangular rods that are far apart from each other. The ends of the two transmission rods that are far apart from each other are rotatably connected to the interior of the two moving plates respectively. A drive bevel gear is fixedly installed on the surface of the two transmission rods.

[0011] Preferably, the upper part of the surface of the driving bevel gear is meshed with a driven bevel gear, the top of the two driven bevel gears is fixedly mounted with a rotating rod, the surface of the two rotating rods is rotatably connected to the inside of the two support frames through three rotating sleeves, and the top of the two rotating rods is fixedly mounted with a driving bevel gear.

[0012] Preferably, one side of the surface of the active bevel gear is meshed with a driven bevel gear, and a drive rod is fixedly installed in the middle of each of the two driven bevel gears. The surfaces of the two drive rods are respectively rotatably connected to the interior of the two support frames through two positioning sleeves, and the two ends of the two drive rods are respectively fixedly connected to four drums.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) During operation, the operator places the fixed frame directly on the transport vehicle. Since the fixed frame is a whole, no additional assembly is required, ensuring the convenience of the operator. Several anti-slip strips can effectively prevent its displacement and sliding. Then the operator starts the drive motor to drive the lower gear to rotate along the rotating seat. When the lower gear rotates, it drives the shaft to rotate inside the four bushings through the upper gear. When the shaft rotates, it drives the first worm to rotate and simultaneously drives the two second worms to rotate along the two positioning seats. When the two second worms rotate, they drive the two rotating shafts to rotate inside the four bearings through the two second worm wheels. When the two rotating shafts rotate, they drive the four threaded sleeves to move through the four threaded rods. When the four threaded sleeves move, they drive the two moving plates to move in opposite directions. When the two moving plates move in opposite directions, they drive the two rectangular rods to extend along the inside of the two rotating tubes, thus ensuring that the two moving plates move while the rotating tubes and rectangular rods still have a transmission effect. (2) When the two moving plates move, they drive the slide bar to slide inside the slide groove, which increases the stability of the two moving plates when they move. When the two moving plates move in opposite directions, they drive the two crossbeams to move in opposite directions through the two support frames, thereby expanding the placement spacing. When the first worm rotates, it also drives the two rotating tubes to rotate inside the two rotating sleeves through the first worm wheel. When the two rotating tubes rotate, they drive the two transmission rods to rotate through the two rectangular rods. When the two transmission rods rotate, they drive the two driven bevel gears to rotate through the two active bevel gears. When the two driven bevel gears rotate, they drive the rotating rods to rotate inside the rotating sleeves. When the two rotating rods rotate, they drive the driven bevel gears to rotate through the active bevel gears. When the two driven bevel gears rotate, they drive the drive rods to rotate inside the positioning sleeves. When the two drive rods rotate, they drive the four drums to rotate along the two rotating frames. When the four drums rotate, they unwind and extend the two slings, thereby allowing for the placement of larger steel coils and improving their applicability. (3) After the fixing frame is adjusted, the operator places the steel coil between the two slings using the hoisting equipment. Both slings are made of wear-resistant and strong polyester fiber material, which can effectively support the steel coil and improve the wear resistance and service life of the two slings. At the same time, since the two slings are flexible load-bearing components, they can prevent the steel coil from being crushed and damaged. (4) This steel coil transport fixture can be adapted to the diameter of the steel coil, so that it can stably place steel coils of different sizes, and will not cause pressure damage between the steel coil and the fixture, thus ensuring the later use of the steel coil.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] Example 1, by Figures 1 to 9The present invention includes a base plate 1, with movable plates 2 inserted into both sides of the base plate 1. Support frames 3 are fixedly installed on the upper side of each of the two movable plates 2. Cross beams 4 are fixedly installed on the side of each of the two support frames 3 that are close to each other. Two connecting frames 5 are fixedly installed on the upper side of each of the two cross beams 4. Rollers 6 are rotatably installed on the top of each of the four connecting frames 5. Rotating frames 7 are fixedly installed at both ends of the top of each of the two support frames 3. A roller 8 is rotatably installed on one side of each rotating frame 7. Two slings 9 are wound between the four rollers 8. The slings 9 are made of wear-resistant and strong polyester fiber material. A drive motor 13 is fixedly installed on the inner bottom of the base plate 1 via a mounting base 12. Several anti-slip strips 40 for preventing sliding displacement are fixedly installed on the bottom of the base plate 1. The output end of the drive motor 13 is provided with a transmission assembly. The transmission assembly is connected to the two movable plates 2 and the four drums 8. When the drive motor 13 is running, it outputs power to the two movable plates 2 and the four drums 8 through the transmission assembly, causing the two movable plates 2 to move in opposite directions and causing the four drums 8 to unwind the two slings 9. The inner walls at both ends of the base plate 1 are provided with sliding grooves 11, and the two movable plates 2 are fixedly installed with sliding strips 10 at both ends. The four sliding strips 10 are slidably installed inside the two sliding grooves 11 respectively.

[0018] During operation, the operator places the fixing frame directly on the transport vehicle. Since the fixing frame is a whole, no additional assembly is required, ensuring the convenience of the operator. Several anti-slip strips 40 can effectively prevent displacement and slippage. Then, the operator starts the drive motor 13 to drive the transmission component to operate. When the transmission component operates, it drives the two moving plates 2 to move in opposite directions. When the two moving plates 2 move, they both drive the slide strips 10 to slide inside the slide groove 11, which increases the stability of the two moving plates 2 when they move. When the two moving plates 2 move in opposite directions, they will drive the two crossbeams 4 to move in opposite directions through the two support frames 3, thereby expanding the placement spacing. While the transmission components are operating, they also drive the four drums 8 to rotate along the two rotating frames 7. When the four drums 8 rotate, they will unwind and extend the two slings 9, thereby allowing for the placement of larger steel coils and improving their applicability. After the fixed frame is adjusted, the operator uses the hoisting equipment to place the steel coil between the two slings 9. Both slings 9 are made of wear-resistant and strong polyester fiber material, which can effectively support the steel coil and improve the wear resistance and service life of the two slings 9. At the same time, since the two slings 9 are flexible load-bearing components, they can prevent the steel coil from being crushed and damaged. This allows the steel coil transport and fixing frame to be adaptively adjusted according to the diameter of the steel coil, so that it can stably place steel coils of different sizes without causing pressure damage between the steel coil and the fixing frame, thus ensuring the later use of the steel coil.

[0019] In Embodiment 2, based on Embodiment 1, the transmission assembly includes a lower gear 14, a rotating seat 15 is rotatably mounted on one side of the lower gear 14, the bottom of the rotating seat 15 is fixedly connected to the inner bottom of the base plate 1, an upper gear 16 is meshed with the upper part of the lower gear 14, a shaft 17 is fixedly mounted in the middle of the upper gear 16, and four bushings 18 are rotatably mounted at equal intervals on the surface of the shaft 17, the bottom of each of the four bushings 18 is fixedly connected to the inner bottom of the base plate 1. The operator starts the drive motor 13 to drive the lower gear 14 to rotate along the rotating seat 15. When the lower gear 14 rotates, it drives the shaft 17 to rotate inside the four bushings 18 through the upper gear 16.

[0020] A first worm gear 19 is fixedly installed in the middle of the shaft 17, and a second worm gear 20 is fixedly installed at both ends of the shaft 17.

A second worm wheel 22 is meshed with the lower part of the surface of the two second worm gears 20. A rotating shaft 23 is fixedly installed in the middle of the two second worm wheels 22. Bearings 24 are rotatably installed at both ends of the surface of the two rotating shafts 23. The bottom of the four bearings 24 is fixedly connected to the inner bottom of the base plate 1. When the shaft 17 rotates, it drives the first worm 19 to rotate, and at the same time drives the two second worms 20 to rotate along the two positioning seats 21. When the two second worms 20 rotate, they drive the two rotating shafts 23 to rotate inside the four bearings 24 through the two second worm wheels 22.

[0021] Both ends of the two rotating shafts 23 are fixedly installed with threaded rods 25, and the surfaces of the four threaded rods 25 are threadedly connected with threaded sleeves 26. The four threaded sleeves 26 are respectively fixedly installed inside the two movable plates 2.

[0022] When the two rotating shafts 23 rotate, they drive the four threaded sleeves 26 to move through the four threaded rods 25. When the four threaded sleeves 26 move, they drive the two moving plates 2 to move in opposite directions. When the two moving plates 2 move in opposite directions, they drive the two crossbeams 4 to move in opposite directions through the two support frames 3, thereby expanding the placement spacing.

[0023] In Example 3, based on Example 2, a first worm gear 27 is meshed and connected to the lower part of the surface of the first worm 19. Rotary tubes 28 are fixedly installed on both sides of the first worm gear 27. Rotary sleeves 29 are rotatably installed at the ends of the two rotating tubes 28 that are close to each other. The bottoms of the two rotating sleeves 29 are fixedly connected to the inner bottom of the base plate 1. Rectangular rods 30 are movably inserted into the interior of the two rotating tubes 28. Transmission rods 31 are fixedly installed at the ends of the two rectangular rods 30 that are far apart from each other. The ends of the two transmission rods 31 that are far apart from each other are rotatably connected to the interior of the two moving plates 2 respectively. Active bevel gears 32 are fixedly installed on the surface of the two transmission rods 31. While the first worm gear 19 rotates, it also drives the two rotating tubes 28 to rotate inside the two rotating sleeves 29 through the first worm wheel 27. When the two rotating tubes 28 rotate, they drive the two transmission rods 31 to rotate through the two rectangular rods 30. When the two transmission rods 31 rotate, they drive the two active bevel gears 32 to rotate. When the two movable plates 2 move back to back, they will cause the two rectangular rods 30 to extend along the inside of the two rotating tubes 28, so that while ensuring the movement of the two movable plates 2, the rotating tubes 28 and the rectangular rods 30 still have a transmission effect.

[0024] The upper part of the surface of the driving bevel gear 32 is meshed with the driven bevel gear 33. The top of each of the two driven bevel gears 33 is fixedly mounted with a rotating rod 34. The surface of each of the two rotating rods 34 is rotatably connected to the interior of each of the two support frames 3 through three rotating sleeves 35. The top of each of the two rotating rods 34 is fixedly mounted with a driving bevel gear 36. One side of the surface of each of the driving bevel gears 36 is meshed with a driven bevel gear 37. The middle of each of the two driven bevel gears 37 is fixedly mounted with a drive rod 38. The surface of each of the two drive rods 38 is rotatably connected to the interior of each of the two support frames 3 through two positioning sleeves 39. The two ends of each drive rod 38 are fixedly connected to four drums 8.

[0025] When the two driving bevel gears 32 rotate, they drive the two driven bevel gears 33 to rotate. When the two driven bevel gears 33 rotate, they drive the rotating rod 34 to rotate inside the rotating sleeve 35. When the two rotating rods 34 rotate, they drive the driven bevel gears 37 to rotate through the driving bevel gear 36. When the two driven bevel gears 37 rotate, they drive the drive rod 38 to rotate inside the positioning sleeve 39. When the two drive rods 38 rotate, they drive the four drums 8 to rotate along the two rotating frames 7. When the four drums 8 rotate, they unwind and extend the two slings 9, thereby allowing larger steel coils to be placed and improving their applicability.
