Description

Technical Field

[0001] This utility model relates to the field of steel rolling equipment technology, specifically to a steel coil car with a tail coil turning function and a waste tail coil collection system. Background Technology

[0002] In existing cold rolling single-stand mills and leveling units, after steel coils are rolled and slit, the waste coils on the uncoiler or coiler are generally unloaded from the coil car to a fixed saddle; then, they are hoisted by an overhead crane to a waste collection box. However, this structure has the following drawbacks: due to the small outer diameter of the waste coils, they usually cannot be stored on the fixed saddle and need to be hoisted away by the overhead crane in a timely manner; otherwise, the coil car cannot continue to operate, affecting the unit's production. Another method is to use a dedicated mobile clamp device to unload the waste coils and send them to the waste collection box for centralized hoisting and processing, thereby reducing the frequency of overhead crane use. However, this method involves relatively large equipment investment and occupies steel coil transportation space, which is not conducive to production operations. Utility Model Content

[0003] To address the aforementioned shortcomings of existing technologies, a steel coil car with a tail coil flipping function and a waste tail coil collection system are provided. This system achieves the goal of reducing the frequency of overhead crane use, lowering operating costs, and reducing investment costs while collecting waste tail coils.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] Firstly, a steel coil cart with a tail-turning function includes a frame and idlers, the idlers being mounted on the frame and freely rotatable, with the steel coil placed on the idlers; characterized in that it includes a flip plate and a drive assembly; one end of the flip plate is rotatably connected to the frame; the drive assembly is mounted on the frame, connected to the rotating end of the flip plate, and drives the flip plate to rotate; the initial position of the flip plate is not in contact with the steel coil, and the rotation of the flip plate actuates the waste tail coil, causing the waste tail coil to roll down along the guide plate to the external waste collection frame.

[0006] According to the above technical solution, the drive unit includes a rotating shaft and a power assembly. The axis of the rotating shaft is parallel to the axis of the idler roller, and the rotating shaft is rotatably connected to the frame through bearings. The rotating shaft is connected to the power assembly, and the power assembly drives the rotating shaft to rotate forward and backward.

[0007] According to the above technical solution, at least one flap is fixed on the rotating shaft.

[0008] According to the above technical solution, the power assembly adopts a rocker arm and a hydraulic cylinder. One end of the rotating shaft extends to the side wall of the frame and is fixedly connected to one end of the rocker arm; one end of the hydraulic cylinder is rotatably connected to the side wall of the frame, and the other end of the hydraulic cylinder is rotatably connected to the other end of the rocker arm.

[0009] According to the above technical solution, the idler rollers are divided into multiple rows along the length of the steel coil, and each row consists of two parallel idler rollers; one end of the flap is rotatably connected to the gap between two adjacent rows of idler rollers.

[0010] According to the above technical solution, two rows of idlers are arranged at intervals along the length of the steel coil, and the flap is located in the gap between the two rows of idlers.

[0011] According to the above technical solution, the rotation center line of the flip plate is located on the symmetrical plane of the center lines of the two idler rollers of the single row of idler rollers.

[0012] Secondly, the waste coil collection system includes a steel coil car with a tail coil flipping function as described above.

[0013] According to the above technical solution, it also includes a track, a waste collection box located on one side of the track, and a guide plate located between the waste collection box and the track. The steel coil car travels on the track. The guide plate is arranged at an angle, with the higher side of the guide plate close to the track. When the steel coil car stops at the guide plate, the position of the waste coil after it is flipped up is directly above the guide plate. The lower side of the guide plate is higher than the height of the external waste collection box near the side of the frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. A tilting plate is installed on the frame, connected to a drive assembly, which drives the tilting plate to rotate on the frame. Initially, the raw material or finished steel coil is located on the idler rollers. At this time, the tilting plate is not in contact with the coil, and it does not protrude from the roller surface, thus not affecting the normal coiling or uncoiling operations. For waste coils located on the idler rollers, when the coil car moves to the track where the waste collection box is located, the tilting plate swings upward, causing the waste coil to roll down along the guide plate into the waste collection box. This device combines coiling, uncoiling, and waste coil tilting functions. The equipment has a simple, compact structure, low cost, saves on overhead crane operating costs, improves unit production efficiency, and reduces human error during operation.

[0016] 2. The hydraulic cylinder is installed on the outside of the frame for easy inspection and maintenance.

[0026] Reference Figures 1-3As shown, the steel coil cart with a tail-turning function provided by this utility model includes a frame 1 and a roller 2. The roller is mounted on the frame and can rotate freely. The steel coil 3 (scrap coil, raw material steel coil, or finished steel coil) is placed on the roller. It includes a flip plate 5 and a drive assembly; one end of the flip plate is rotatably connected to the frame; the drive assembly is mounted on the frame and connected to the rotating end of the flip plate, and drives the flip plate to rotate; the initial position of the flip plate is not in contact with the steel coil. The rotation of the flip plate agitates the scrap coil, causing it to roll down along the outer guide plate 4 to the waste collection frame 9.

[0027] In this embodiment, a flap is installed on the frame, connected to a drive assembly, which drives the flap to rotate on the frame. Initially, the raw material or finished steel coil is located on the idler rollers. At this time, the flap is not in contact with the coil, and the flap does not protrude from the roller surface, thus not affecting the normal coiling or uncoiling operations. For waste coils located on the idler rollers, when the coil carriage moves to a track near the waste collection frame, the flap swings upward, causing the waste coil to roll down along the guide plate into the waste collection frame.

[0028] In embodiment 1, the drive unit includes a rotating shaft 6 and a power assembly. The axis of the rotating shaft is parallel to the axis of the idler roller, and the rotating shaft is rotatably connected to the frame via bearings. The rotating shaft is connected to the power assembly, which drives the rotating shaft to rotate forward and backward. At least one flap is fixedly mounted on the rotating shaft.

[0029] Example 2

[0030] The structure and principle of Embodiment 2 are similar to those of Embodiment 1, except that a different structural form of the power assembly is provided. As shown in the figure, the power assembly specifically uses a swing arm 7 and a hydraulic cylinder 8. One end of the rotating shaft extends to the side wall of the frame and is fixedly connected to one end of the swing arm; one end of the hydraulic cylinder is rotatably connected to the side wall of the frame, and the other end of the hydraulic cylinder is rotatably connected to the other end of the swing arm. In this embodiment, the hydraulic cylinder drives the rotating shaft to rotate via the swing arm, thereby causing the flap to swing up and down. The hydraulic cylinder is installed on the outside of the frame for easy inspection and maintenance.

[0031] The power unit can also take other forms, such as using a motor with forward and reverse rotation functions, directly connected to the shaft or connected through a reducer. However, using a motor is not as effective as using a hydraulic cylinder.

[0032] In Examples 1-3, the idlers are divided into multiple rows along the width of the steel coil, and each row consists of two parallel idlers; one end of the flap is rotatably connected to the gap between two adjacent rows of idlers.

[0033] As shown in the embodiment, two rows of idlers are spaced apart along the width of the steel coil, and a flap is located in the gap between the two rows of idlers.

[0034] To facilitate the installation of the rotating shaft and power components, the rotation center line of the flap is located on the symmetrical plane of the center lines of the two idler rollers of the single row of idler rollers.

[0035] Example 3

[0036] This utility model also provides a waste coil collection system, including any of the steel coil carts with a coil-flipping function described above. It also includes a track 10, a waste collection frame located on one side of the track, and a guide plate located between the waste collection frame and the track. The steel coil cart travels on the track; the guide plate is inclined, with its higher side closer to the track, and when the steel coil cart stops at the guide plate, the position of the flipped waste coil is directly above the guide plate; the lower side of the guide plate is higher than the height of the external waste collection frame near the side of the cart frame.

[0037] The working principle of this utility model:

[0038] During unloading, the steel coil trolley unloads the waste coil from the uncoiler or coiler, then moves the trolley to the waste collection box, where a flap on the trolley is used to pour the waste coil into the collection box for centralized hoisting and processing by an overhead crane. This utility model has a simple and practical structure, improves unit production efficiency, saves operating costs, and reduces accidents caused by manual operation.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
