Background Technology

[0002] In the steel production and logistics process, steel coils, as a common product form, require specialized transport vehicles for transshipment. However, during transportation, existing steel coil transport vehicles are prone to displacement and movement due to road bumps, vehicle starts and stops, etc. This not only causes scratches and bumps on the surface of the steel coils, affecting product quality, but may also lead to safety accidents, such as steel coils falling and injuring people or damaging transport vehicles.

[0003] Currently, while steel coil transport vehicles are equipped with simple clamping or fixing structures, they suffer from several shortcomings. For example, some methods using rope binding are cumbersome, inefficient, and offer inconsistent fixing results, making them unsuitable for steel coils of different specifications. Other clamping devices are complex in structure, costly to manufacture, inconvenient to maintain, and poorly adaptable to different sizes of steel coils, failing to meet the demands for efficient, convenient, and reliable transportation in actual production. Therefore, there is an urgent need to develop a steel coil transport vehicle clamping device that is structurally sound, easy to operate, highly adaptable, and provides excellent fixing results.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figure 1-6 As shown, a steel coil clamping device suitable for a transport vehicle includes clamping arms 1. At least two clamping arms 1 are provided, symmetrically arranged on both sides of the transport vehicle 27. The number of clamping arms 1 can be increased or decreased depending on specific circumstances. Each clamping arm 1 includes a fixed base 2, which is a steel structural component securely installed on the floor of the transport vehicle 27 via welding or bolting. A universal joint 3 is provided on the fixed base 2, with one end connected to the fixed base 2 and the other end connected to a column 4. The universal joint 3 allows for omnidirectional rotation of the column 4. Combined with a lifting mechanism 13, this enables clamping of steel coils 29 of different diameters and widths.

[0019] A connecting seat 6 is rotatably connected to the top of the column 4. A lifting mechanism 13 is fixedly connected to one side of the connecting seat 6. A pressure plate 14 is provided at the movable end of the lifting mechanism 13, and the pressure plate 14 abuts against the surface of the steel coil 29. Specifically, the connecting seat 6 includes a fixing plate 7, a pad 8, and a bushing 9. The pad 8 is provided on one side of the fixing plate 7. The lifting mechanism 13 is fixedly connected to the fixing plate 7 and is located on one side of the pad 8. A bushing 9 is provided on one side of the fixing plate 7. An upper connecting seat 5 is provided at the top of the column 4. The bushing 9 is connected to the upper connecting seat 5 by a pin I 10. A positioning hole 11 is provided on the bushing 9, and a positioning pin 12 passes through the positioning hole 11 to prevent the lifting mechanism 13 from rotating when clamping the steel coil 29. The lifting mechanism 13 is a worm gear screw jack 30. By rotating the handle 32 of the worm gear screw jack 30, the screw 33 is moved back and forth to achieve the clamping or loosening action of the steel coil 29. The worm gear screw jack 30 has a flange at the end of the screw 33. A connecting sleeve 15 is welded to the pressure plate 14, and a flange 16 is welded to the connecting sleeve 15. The pressure plate 14 is fixedly connected to the flange on the screw 33 through the flange 16, and the steel coil 29 is pressed by the pressure plate 14. A buffer pad 17 is provided on the side of the pressure plate 14 near the steel coil 29. The buffer pad 17 is made of high-strength rubber material, which has good elasticity and wear resistance, and can effectively clamp the steel coil 29 while avoiding damage to the surface of the steel coil 29.

[0020] An angle locking device is provided on the column 4, which includes a connecting plate I 18, a hook 19, and a rack assembly. The connecting plate I 18 is located on the side of the column 4 near the steel coil 29. The hook 19 includes a rotating end and a hooking end, and the rotating end is rotatably connected to the column 4 through a pin II. The rack assembly is fixedly connected to the fixing base 2 and is located below the hook 19. The rack assembly includes a rack 20 and side plates 21. Side plates 21 are provided on the left and right sides of the rack 20. The bottom of the side plates 21 is fixedly connected to the fixing base 2. The rack 20 is inclined, and the top of the rack 20 is inclined toward the column 4. The teeth of the rack 20 are located on the upper side of the rack 20, and the hooking end is hooked onto the rack 20. The top of the side plate 21 is provided with a guide plate 22 for limiting the column 4. The guide plate 22 extends from the top of the side plate 21 to the column 4. The column 4 can reciprocate between the two guide plates 22, so that the column 4 can stably approach the steel coil 29 along the guide plate 22.

[0021] The angle locking device also includes a reset device, which includes a connecting plate II 23, a reset rod 24, and a connecting rod 25. The connecting plate II 23 is fixedly connected to one side of the column 4 and is located above the connecting plate I 18. The reset rod 24 is rotatably connected to the connecting plate II 23. The reset rod 24 is provided with a connecting rod 25. One end of the connecting rod 25 is rotatably connected to the reset rod 24, and the other end is rotatably connected to the hook 19.

[0022] Specifically, the reset rod 24 is L-shaped. The corner of the L-shaped reset rod 24 is rotatably connected to the connecting plate II 23. The two free ends of the L-shaped reset rod 24 extend towards one side of the steel coil 29, and extend upwards and downwards respectively. One end of the connecting rod 25 is rotatably connected to the lower free end, and the other end of the connecting rod 25 is rotatably connected to the upper side of the hook 19 via the connecting block 26. By setting the reset rod 24, the fixing effect of the hook 19 is further strengthened. When the reset rod 24 is raised upwards, the hook is more securely engaged, and when the reset rod 24 is pressed down, the hook 19 can easily disengage from the rack 20.

[0023] When it is necessary to clamp and fix the steel coil 29, the steel coil 29 is first hoisted onto the V-shaped saddle 28 of the transport vehicle 27. The operator picks up the uprights 4 installed on both sides of the end face of the steel coil 29 and moves the uprights 4 along the path between the two guide plates 22, changing from the initial state when the clamping arm 1 is vertical to the clamping state that approaches and clamps the steel coil. The swing position of the uprights 4 is adjusted according to the width of the steel coil 29. After adjusting to the appropriate position, the hook 19 is hung on the rack 20. The left and right positioning of the uprights 4 is achieved by the guide plates 22. The connecting seat 6 is rotated to adjust the worm gear screw jack 30 and the pressure plate 14 so that they are initially in contact with the end face of the steel coil 29. Then, the positioning pin 12 is inserted for positioning to prevent the worm gear screw jack 30 from rotating. Subsequently, the operator rotates the handle 32 on the worm gear screw jack 30 to drive the screw 33 to move the pressure plate 14, gradually approaching the end face of the steel coil 29. As the pressure plates 14 on both sides continue to move, the steel coil 29 is clamped by the buffer pads 17 on both sides until a suitable clamping force is reached, thus achieving stable fixation of the steel coil 29. After transportation is completed, the clamping arm 1 is returned to its initial state from the clamping state, and the operating handle 32 is rotated in the opposite direction to disengage the pressure plate 14 from the surface of the steel coil 29. At this time, a gap appears between the pressure plate 14 and the surface of the steel coil 29. Then, the column 4 is pressed down further to allow the hook 19 to move. The reset rod 24 is pulled up to disengage the hook 19 from the rack 20. The pressure plate 14 moves away from the steel coil 29, and the steel coil 29 is released from its fixation, allowing it to be hoisted away from the transport vehicle 27.
