Description

Technical Field

[0001] The utility model relates to the technical field of coil loading trolleys, in particular to a strip cold rolling coil loading trolley. Background Art

[0002] A strip, also known as a steel strip, is a narrow and long steel plate produced by various rolling mills to meet the needs of different industrial sectors for industrial production of various metals or mechanical products.

[0003] The Chinese utility model patent with the publication number CN216862719U in the prior art proposes a strip cold rolling coil loading trolley. The coil loading trolley drives a double-headed reverse screw to rotate through a second motor by arranging a sliding plate and a connecting plate, and the double-headed reverse screw drives two sliding plates to slide towards the opposite ends, so as to drive a drag plate to rise for coil loading in cooperation with the connecting plate. And the drag plate is provided with a placing groove for conveniently placing the strip. Since the cross-section of the placing groove is "V"-shaped, the strip can be prevented from rolling, and the use stability is improved.

[0004] However, the above-mentioned coil loading trolley in the prior art cannot move out the strip coil through its own structure and function. Therefore, it is not convenient to transport the strip coil to a platform at a higher position, and the practicability is poor. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a strip cold rolling coil loading trolley which can move out the strip coil through its own structure, is convenient to transport the strip coil to a platform at a higher position, and has good practicability.

[0006] A coil loading trolley for cold rolling of strip steel of the present utility model includes a trolley chassis, a lifting mechanism and a bracket. The lifting mechanism is installed on the trolley chassis, and the bracket is installed on the lifting mechanism. A V-shaped groove is provided on the upper end surface of the bracket. It also includes two support plates, two universal wheels, two hook plates, two steering engines and two cams. The two support plates are respectively slidably installed on the inner walls of the V-shaped grooves of the bracket. The two universal wheels are respectively installed on the lower end surfaces of the front ends of the two support plates. One ends of the two hook plates are respectively rotatably connected to the front and rear ends of one support plate, and the other ends of the two hook plates are respectively hooked and connected to the hanging rods on the front and rear ends of the other support plate. The two steering engines are respectively installed on the front and rear ends of the other support plate, and the output shafts of the two steering engines are respectively installed with cams. The two cams are respectively in sliding contact with the two hook plates. During operation, the two hook plates are respectively hung on the two hanging rods of the support plates, so as to close the two support plates to form an integral V-shaped support plate. The two support plates are located in the V-shaped groove of the bracket. The strip steel coil is placed on the two support plates through a loading device. The trolley chassis moves to the loading platform. The lifting mechanism raises the bracket, so that the two support plates are higher than the loading platform. The two support plates extend outwards, so that the two universal wheels roll on the loading platform. When the two support plates carry the strip steel coil and move onto the loading platform, the two steering engines drive the two cams to rotate synchronously, so that the two cams respectively push the two hook plates downwards, so that the two hook plates are respectively disengaged from the two hanging rods. At this time, under the action of the gravity of the strip steel coil, the two support plates are pushed to both sides, and the two universal wheels turn at the same time to make the two support plates move more smoothly to both sides, so that the strip steel coil falls onto the loading platform through the space between the two support plates. The trolley chassis moves away from the loading platform, so that the two support plates are pulled out from the loading platform. The lifting mechanism lowers the bracket to reset, closes the two support plates close to each other, and uses the two hook plates to lock the two support plates, realizing the removal of the strip steel coil through its own structure, facilitating the transportation of the strip steel coil to a platform at a higher position, and having good practicability.

The piston rods of the two push cylinders 13 extend to push the two support plates 4 outwards, causing the two universal wheels 5 to roll on the loading platform. Then, after the two support plates 4 carry the strip coil and move onto the loading platform, the two steering gears 7 drive the two cams 8 to rotate synchronously, causing the two cams 8 to respectively push the two hook plates 6 downwards, causing the two hook plates 6 to disengage from the two hanging rods respectively. At this time, under the action of the gravity of the strip coil, the two support plates 4 are pushed to both sides, and the two universal wheels 5 turn simultaneously to make the movement of the two support plates 4 to both sides smoother, so that the strip coil falls onto the loading platform through the space between the two support plates 4. Finally, the trolley chassis 1 moves away from the loading platform, causing the two support plates 4 to be withdrawn from the loading platform. The lifting mechanism 2 lowers the carriage 3 to its original position. The two reduction motors 16 drive the two gears 17 to rotate synchronously, causing the two gears 17 to move the two chute push plates 15 and the two support plates 4 inwards by engaging the two racks 18, thereby closing the two support plates 4. Use the two hook plates 6 to lock the two support plates 4, and the piston rods of the two push cylinders 13 contract to pull the two support plates 4 back to the carriage 3 to reset.
