Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer processing technology, and in particular to a rack for holding transformer steel sheets. Background Technology
[0002] The iron cores of large transformers are typically manufactured by stacking steel sheets. These sheets need to be punched into a predetermined shape using a punching device. After punching, operators transfer them to the stacking area for core stacking. Currently, the punched steel sheets are placed directly on the workbench. Firstly, these steel sheets are arranged in various postures, requiring them to be aligned during transfer. This process can easily damage the insulation layer of the steel sheets. Secondly, it is inconvenient to transfer multiple steel sheets. If the ends of the steel sheets have sharp points, they can easily deform during transfer, thus affecting the stacking operation. Utility Model Content
[0003] This utility model provides a storage rack for transformer steel sheets to overcome the shortcomings of the prior art, and solves the problems of inconvenient unloading and storage of steel sheets, and easy deformation of the ends during transfer.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A rack for storing transformer steel sheets includes a long strip with skirts bent downwards on both sides. Two pairs of connecting screws are provided on the skirts, and each pair of connecting screws has a side vertical plate fixed to its ends by nuts. A groove is provided on one side of the upper end of each side vertical plate. The long strip supports the steel sheets, while the side vertical plates limit the movement of the steel sheets on both sides, ensuring that the steel sheets are stacked neatly.
[0006] The upper end of the side vertical plate is provided with an upper plate, on which a concave handle is installed. A pair of oblong holes are opened at both ends of the upper plate, and movable screws are inserted into the oblong holes. The upper end of the movable screw located at the same end is connected to an upper movable plate by a thread, and the lower end of the movable screw located at the same end is connected to a lower clamping plate by a thread. The lower clamping plate is inserted into the groove to connect and fix the upper plate to the side vertical plate, thereby facilitating the transfer of multiple steel plates.
[0007] Furthermore, end baffles are bent at both ends of the upper plate to limit the ends of the steel sheet and ensure safety during transfer.
[0008] Furthermore, clearance holes are provided on the end baffle to prevent the sharp ends of the steel sheet from contacting each other and causing deformation at both ends of the steel sheet.
[0009] Furthermore, side plates are formed at both ends of the lower clamping plate, and the side plates are located outside the side vertical plates to limit the lower clamping plate, thereby ensuring safety during transfer.
[0010] Furthermore, the inner side of the upper movable plate is in contact with a spring piece, which is fixed to the upper plate by a fixing strip. After the transfer is completed, the upper movable plate can be moved outward under the action of the spring piece, so as to cancel the fixed connection operation of the lower clamping plate.
[0011] Furthermore, to facilitate the simultaneous clamping operation of the lower plate and ensure stability after clamping, an inner top rotating plate is provided on the outer wall of the upper moving plate. A hinge screw is rotatably mounted on the inner top rotating plate and is threaded to the upper plate. An actuating end shaft is provided at the outer end of the inner top rotating plate, and a moving plate is fitted on the actuating end shaft. Slotted holes are opened at both ends of the moving plate, and the actuating end shaft passes through the slotted holes. A pair of guide elongated holes are opened on the moving plate, and the vertical section of the concave handle passes through the guide elongated holes.
[0012] Furthermore, to facilitate the movement of the movable plate, rectangular holes are provided on the movable plate.
[0013] Furthermore, in order to limit the rotation of the inner top rotating plate, stop pins are provided at both ends of the upper plate. The stop pins act on one side of the inner top rotating plate to limit its rotation.
[0014] The advantages of the above technical solution are:
[0015] This utility model can be used as a storage box for receiving steel sheets. It can ensure the neatness of the steel sheets during storage, facilitate the transfer of steel sheets, and ensure safety during transfer while avoiding adverse effects on the steel sheets. Attached Figure Description
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings.
[0017] Figure 1 A three-dimensional structural diagram of one embodiment is shown.
[0018] Figure 2 A magnified view of point A is shown.
[0019] Figure 3 A magnified view of point B is shown. Detailed Implementation
[0020] like Figures 1-3 As shown, a storage rack for transformer steel sheets includes a long strip 1 with skirts 10 bent downwards on both sides. Two pairs of connecting screws 2 are provided on the skirts 10, and each pair of connecting screws 2 has a side vertical plate 20 fixed to its ends by nuts. A groove is provided on one side of the upper end of the side vertical plate 20.
[0021] The upper end of the side vertical plate 20 is provided with an upper plate 3, and the two ends of the upper plate 3 are respectively bent with end baffles 6. The end baffles 6 are provided with clearance holes, and the upper plate 3 is equipped with a concave handle 47.
[0022] A pair of oblong holes 31 are respectively opened at both ends of the upper plate 3. A movable screw 30 is inserted into the oblong hole 31. The upper end of the movable screw 30 located at the same end is connected to the upper movable plate 32 by thread. The lower end of the movable screw 30 located at the same end is connected to the lower clamping plate 33 by thread. The lower clamping plate 33 is inserted into the groove. Side plates 34 are respectively formed at both ends of the lower clamping plate 33. The side plates 34 are located outside the side vertical plate 20.
[0023] The inner side of the upper movable plate 32 contacts a spring piece 36, which is fixed to the upper plate 3 by a fixing strip 35. The outer wall of the upper movable plate 32 contacts an inner top rotating plate 40, on which a hinge screw 4 is rotatably mounted. The hinge screw 4 is threadedly connected to the upper plate 3. The outer end of the inner top rotating plate 40 is provided with an actuating end shaft 41, on which a movable plate 44 is sleeved. The two ends of the movable plate 44 are respectively provided with strip holes 43, and the actuating end shaft 41 passes through the strip holes 43. The movable plate 44 is provided with a pair of guide elongated holes 46, and the vertical section of the concave handle 47 passes through the guide elongated holes 46. The movable plate 44 is provided with a rectangular hole 45.
[0024] When used as a storage box in this embodiment, the holding rack is placed at the discharge end of the punching device. The punched steel sheet is directly placed on the long strip 1 and between the side vertical plates 20. The presence of the side vertical plates 20 enables the steel sheet to be stacked neatly.
[0025] In this embodiment, when transferring the steel sheet, the operator moves the upper plate 3 to the upper end of the side vertical plate 20, and then moves the moving plate 44. When the moving plate 44 moves, it acts on the end shaft 41 through the inner wall of the strip hole 43, thereby causing the inner top rotating plate 40 to rotate. The rotation of the inner top rotating plate 40 will cause its inner end to act on the outer wall of the upper moving plate 32, and cause the upper moving plate 32 to move inward, and cause the lower clamping plate 33 to pass through the groove. At this time, the spring piece 36 is compressed. Then the operator transfers the steel sheet to the stacking position through the concave handle 47. Then the operator moves the moving plate 44 again. After that, as the inner top rotating plate 40 loses its effect on the upper moving plate 32, the upper moving plate 32 and the lower clamping plate 33 move outward. Then the upper plate 3 is removed, and then the steel sheet is picked up and stacked.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
