Description

Technical Field

[0001] The utility model belongs to the field of handling and transporting equipment for steel coils, and particularly relates to a material-taking and transporting roller path for steel coils. Background Art

[0002] After the steel coils produced by our enterprise are packed, they need to be transported from the shelving to the transporting roller path for transportation. Before the present utility model was made, our enterprise usually used lifting tools or forklifts to transport the packed steel coils to the transporting roller path. Due to the large volume and weight of the steel coils, both the handling methods using lifting tools and forklifts have inconveniences and potential safety hazards. Content of the Utility Model

[0003] Based on the deficiencies existing in the prior art of using lifting tools or forklifts to transport steel coils from the shelving to the transporting roller path, the present application provides a material-taking and transporting roller path for steel coils, which includes a first transporting roller group, a second transporting roller group, a third transporting roller group, a frame, a retaining bar, a telescopic tongue, a slider, a chute body, and a driving cylinder;

[0004] The first transporting roller group includes a plurality of first transporting rollers, and the plurality of first transporting rollers are arranged in parallel and are respectively rotatably connected to the frame through bearings. The second transporting roller group includes a plurality of second transporting rollers, and the plurality of second transporting rollers are arranged in parallel and are respectively rotatably connected to the frame through bearings;

[0005] Two mutually parallel retaining bars are arranged between the first transporting roller group and the second transporting roller group. The retaining bars are fixedly connected to the frame through corresponding brackets, and the retaining bars are perpendicular to the first transporting rollers. A third transporting roller group is arranged outside each retaining bar. The third transporting roller group includes a plurality of third transporting rollers. One end of each third transporting roller is rotatably connected to the frame through a bearing, and the other end is rotatably connected to the corresponding retaining bar through a bearing; the size of the retaining bar is adapted to the inner diameter size of the steel coil. Since the steel coil is wound by steel plates, when the steel coil is placed on the roller path, the retaining bar with a suitable size can prevent the inner diameter of the steel coil from slipping and collapsing at the gap between the two retaining bars;

[0006] A telescopic tongue is arranged between the two retaining bars on the side close to the first transporting roller group. The bottom surface of the telescopic tongue is fixedly connected with a slider. The slider is placed in the chute body. The chute body is fixedly connected to the frame through a corresponding bracket. A driving cylinder is arranged below the slider. The cylinder end of the driving cylinder is fixedly connected to the frame through a corresponding bracket, and the telescopic rod end of the driving cylinder is fixedly connected to the slider. The driving cylinder is specifically a double-link cylinder. Under the drive of the double-link cylinder, the telescopic tongue can extend and retract;

[0007] The side of the frame close to the second transmission roller group is hinged to the ground or the base through a rotating shaft, and the other side of the frame is connected to the electric hoist through a pull rope. The electric hoist is set next to the frame through a gantry frame, and one side of the frame can be pulled up under the drive of the electric hoist.

[0008] Preferably, a first sprocket is fixedly connected to one end of the first transmission roller, the second transmission roller and the third transmission roller, and a second sprocket is fixedly connected to the output shaft of the reduction motor. The first sprocket and the second sprocket are connected by a chain, and the reduction motor is also fixedly connected to the frame through a corresponding bracket. In this way, each transmission roller can operate under the drive of the reduction motor.

[0009] The working principle of the above-mentioned steel coil material collection and transmission roller is as follows: when one side of the frame rotates around the axis and the other side is pulled up by the electric hoist until the frame is perpendicular to the ground or the base, the telescopic picking tongue extends out of the roller surface under the drive of the drive cylinder, and the steel coil packed on the shelf can be translated to the telescopic picking tongue under the push of the hydraulic push rod, that is, the end face of the steel coil is pushed to fit the roller surface, and the inner ring of the steel coil is suspended on the telescopic picking tongue, and then the hydraulic push rod is retracted, and the electric hoist releases the rope to make the frame fall back to a horizontal position, and the telescopic picking tongue retracts to below the roller surface. At this time, driven by the reduction motor, the first transmission roller group, the second transmission roller group and the third transmission roller group rotate, so that the steel coil can be transported. Of course, other conventional transmission rollers can be set next to the frame to transport the steel coil to the designated location.

[0010] Furthermore, an obstacle avoidance gap is provided on the baffle bar. When the steel coil is moved horizontally from the shelf to the telescopic tongue under the push of the hydraulic push rod, the end of the hydraulic push rod can pass through the obstacle avoidance gap of the baffle bar to avoid obstruction of its operation.

[0011] Through the above technical solution, the utility model has at least the following beneficial effects:

[0012] The steel coil feeding and conveying roller conveyor described in the present application has a frame that can be flipped and the steel coils can be taken out by a telescopic picking tongue. Its operation is stable, safe and reliable, and the packaged steel coils can be transferred from the shelf to the conveying roller conveyor conveniently and quickly without the use of equipment such as slings and forklifts.

[0019] The first transport roller group 1 includes a plurality of first transport rollers, the plurality of first transport rollers are arranged parallel to each other and are respectively rotatably connected to the frame 4 through bearings. The second transport roller group 2 includes a plurality of second transport rollers, the plurality of second transport rollers are arranged parallel to each other and are respectively rotatably connected to the frame 4 through bearings;

[0020] Two mutually parallel baffles 5 are provided between the first conveying roller group 1 and the second conveying roller group 2. The baffles 5 are fixedly connected to the frame 4 via corresponding brackets 16. The baffles 5 are perpendicular to the first conveying rollers. A third conveying roller group 3 is provided on the outside of each baffle 5. The third conveying roller group 3 includes a plurality of mutually parallel third conveying rollers. One end of the third conveying roller is rotatably connected to the frame 4 via a bearing, and the other end is rotatably connected to the corresponding baffle 5 via a bearing. The size of the baffle 5 is adapted to the size of the inner ring of the steel coil. Since the steel coil is made of wound steel plates, when the steel coil is placed on the conveying roller, the baffle 5 of appropriate size can prevent the inner ring of the steel coil from slipping and collapsing in the gap between the two baffles 5.

[0021] A telescopic tongue 6 is provided between the two baffles 5 on one side close to the first transport roller group 1. A slider 7 is fixedly connected to the bottom surface of the telescopic tongue 6. The slider 7 is placed in a chute body 8. The chute body 8 is fixedly connected to the frame 4 through a corresponding bracket 16. A driving cylinder 14 is provided below the slider 7. The cylinder end of the driving cylinder 14 is fixedly connected to the frame 4 through a corresponding bracket 16. The telescopic rod end of the driving cylinder 14 is fixedly connected to the slider 7. The driving cylinder 14 is specifically a double cylinder. Under the drive of the double cylinder, the telescopic tongue 6 can be extended and retracted;

[0022] The side of the frame 4 close to the second transmission roller group 2 is hinged to the ground or the base 9 through a rotating shaft 10, and the other side of the frame 4 is connected to the electric hoist 12 through a pull rope 11. The electric hoist 12 is arranged next to the frame 4 through a gantry 13, and one side of the frame 4 can be pulled up under the drive of the electric hoist 12.

[0023] refer to Figure 2 A first sprocket 21 is fixedly connected to one end of the first transmission roller, the second transmission roller and the third transmission roller, and a second sprocket 22 is fixedly connected to the output shaft of the reduction motor 15. The first sprocket 21 and the second sprocket 22 are connected by a chain. The reduction motor 15 is also fixedly connected to the frame 4 through the corresponding bracket 16. In this way, each transmission roller can operate under the drive of the reduction motor 15.

[0024] The working principle of the coil picking and conveying roller table is as follows: When one side of the frame 4 rotates around the axis and the other side is lifted by the electric hoist 12 until the frame 4 is perpendicular to the ground or the base 9, the telescopic tongue 6 extends out of the roller table surface under the drive of the drive cylinder 14. The packaged coil on the shelving can be translated onto the telescopic tongue 6 under the push of the hydraulic push rod, that is, the push makes the end face of the coil fit the roller table surface, and the inner ring of the coil hangs on the telescopic tongue 6. Then, the hydraulic push rod is retracted. After the electric hoist 12 pays out the rope and the frame 4 falls back to the horizontal position, the telescopic tongue 6 retracts below the roller table surface. At this time, under the drive of the reduction motor 15, the first conveying roller group 1, the second conveying roller group 2, and the third conveying roller group 3 rotate, enabling the coil to be transported. Of course, other conventional conveying roller tables can be arranged beside the frame 4 to transfer and transport the coil to the designated position.

[0025] In a specific embodiment, with reference to Figure 1 , an obstacle avoidance notch 501 is further formed on the retaining bar 5. When the coil is translated from the shelving to the telescopic tongue 6 under the push of the hydraulic push rod, the end of the hydraulic push rod can pass through the obstacle avoidance notch 501 of the retaining bar 5 to avoid hindrance to its operation.

[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Based on the inspiration of the present utility model, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
