DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] Specific embodiment 1 of a steel plate storage and transportation device of the utility model:

[0021] The structure of the steel plate storage and transfer device is as follows: Figure 1-Figure 3 As shown, it includes a lifting gantry 1, two platform steel frames 2 and a moving trolley 3. The lifting gantry is mainly composed of a top beam and two vertical support frames supported below the top beam. A vertical track 4 and a lifting mechanism are arranged on the vertical support frame. The vertical track 4 is located on the inner side of the vertical support frame and the platform steel frame cooperates with the vertical track 4 to move up and down. The lifting mechanism is used to drive the platform steel frame to move up and down relative to the vertical track 4, and includes a lifting motor 5 and a fixed pulley 6. The fixed pulley 6 is arranged at the top of the vertical support frame. A movable pulley 7 is arranged on the platform steel frame. The movable pulley 7 is connected to the lifting motor and the fixed pulley through a steel wire rope and moves up and down under the action of the lifting motor 5. A transverse track 12 is arranged on the platform steel frame. The moving trolley 3 is located between the two platform steel frames 12 and cooperates with the transverse track 12 to move horizontally.

[0022] like Figure 4As shown, the mobile trolley includes an upper frame 31 and a lower frame 32. The upper frame 31 is provided with a moving wheel group and a trolley driving mechanism. The trolley driving component is used to drive the moving wheel group to move along the transverse track 12. In this embodiment, the cross section of the transverse track 12 is U-shaped and the opening is facing the horizontal direction. The moving wheel group includes a guide wheel 9 and a power wheel 8. The power wheel 8 is located above the transverse track 12 and rolls with the upper side of the transverse track 12. The trolley driving component includes a reduction motor. The reduction motor is arranged at the power wheel 8 and is used to directly drive the power wheel 8 to move. The guide wheel 9 is located on the inner side of the transverse track and is used to guide the movement along the transverse track under the action of the power wheel 8. The mobile trolley moves using the above-mentioned moving wheel group that is hung on the power wheel and guided by the guide wheel, so as to ensure that the mobile trolley and the steel plate move smoothly and reliably.

[0023] The lower frame 32 is located below the upper frame 31 and is provided with an adsorption mechanism for adsorbing the steel plate. In this embodiment, the adsorption mechanism is a vacuum suction cup 11. In order to ensure firm adsorption and adaptability to steel plates of different sizes, a plurality of vacuum suction cups 11 are provided and arranged in an array on the lower frame. A frame lifting mechanism for driving the lower frame to move up and down relative to the upper frame is provided between the upper frame 31 and the lower frame 32; the frame lifting mechanism includes four lifting motors 10. The lifting motor 10 is provided on the upper frame 21. The output end of the lifting motor 10 extends downward and is connected to a screw rod. The screw rod is threadedly connected to the lower frame 32. The four lifting motors are distributed in rectangular corners. The lifting motor is driven to rotate forward / reverse, and the lower frame 32 is driven to lift / fall through the screw rod. With the adsorption effect of the vacuum suction cup 11, the adsorption and grasping of steel plates of different specifications can be achieved.

[0024] The steel plate storage and transfer device of the utility model is used in conjunction with a steel plate conveying device and a warehouse steel device when transferring steel plates. The steel plate conveying device for conveying steel plates is located below the lifting gantry and is responsible for the incoming steel plates. The warehouse steel device is located on one side of the lifting gantry and is used to store steel plates. Multiple layers of storage locations for placing steel plates are arranged thereon, and each layer of storage location for steel plates is also provided with a warehouse transverse track. Therefore, the side where the lifting gantry is connected to the warehouse steel device is the material transfer side, and the other side is the idle side. Safety fences (not shown in the figure) are arranged at both ends of the lifting gantry 1 and on the outside of the idle side to realize the personnel safety protection function.

[0025] like Figure 5As shown, a limit switch 13 and a laser beam sensor 14 are provided on the side of the platform steel frame close to the idle side, and both the limit switch 13 and the laser beam sensor 14 are used to detect the position of the moving trolley. The limit switch 13 is located at the outer edge of the platform steel frame and is used to detect whether the moving trolley has reached the end of the stroke; the laser beam sensor 14 is located on the inner side of the limit switch and is used to detect whether the moving trolley is close to the end of the stroke. When the moving trolley completes the storage of steel plates and moves along the transverse track toward the lifting gantry, after the laser beam sensor detects the moving trolley, the controller controls the reduction motor to slow down the moving trolley until the moving trolley touches the limit switch and stops moving, that is, reaches the predetermined position. The above-mentioned limit function can not only ensure that the moving trolley moves into place and is aligned with the steel plate for adsorption, but also avoid the collision between the moving trolley and the external safety fence to cause damage.

[0026] The actual transfer process of the steel plate storage and transfer device of the present invention is as follows: after the steel plate is delivered by the steel plate conveying device, the lifting motor uses the steel wire rope to lower the mobile trolley along the vertical track, and then the lifting motor is started. Under the action of the lifting motor and the screw, the lower frame is driven to descend relative to the upper frame, and then the vacuum suction cup is turned on to adsorb the steel plate. After the steel plate is adsorbed, the lower frame is moved to a predetermined position with the steel plate, and then the lifting motor is turned on to lift the mobile trolley to a predetermined storage height. After that, the reduction motor drives the mobile trolley to move along the horizontal track to the horizontal track of the warehouse in the storage position, and the steel plate is released after moving to the predetermined storage position, completing the storage of the steel plate.

[0027] The steel plate storage and transfer device of the utility model has the advantages of reasonable and reliable structure, easy manufacturing and low cost. It is combined with an array-type vacuum suction cup to adsorb steel plates, and can quickly, accurately and steadily adsorb steel plates of different sizes, and has the advantages of smooth movement, automatic adsorption and efficient transfer. The storage and retrieval of steel plates are all automated by mechanical means, which reduces the operating costs of the production line while meeting the requirements of intelligent warehousing of steel plates. In addition, the mobile cart can be moved directly to the inside of the warehouse steel device, and can be freely moved and stored at different heights, making the stacking more regular and safe.

[0028] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
