Description

Technical Field

[0001] This utility model belongs to the field of cranes, specifically an intelligent electromagnetic chuck bridge crane. Background Technology

[0002] A bridge crane is a type of lifting equipment that spans across workshops, warehouses, and material yards to lift and transport materials. It mainly consists of a bridge frame, trolley, hoisting mechanism, trolley traveling mechanism, and operator's cab. It is driven by an electric motor to lift and transport materials. An electromagnetic chuck is a device that uses electromagnetic principles to achieve adsorption. In the handling of magnetic materials, bridge cranes equipped with electromagnetic chucks are usually used for lifting operations.

[0003] Electromagnetic chucks are typically connected to the lifting mechanism of a crane trolley via hooks or chains. When lifting an item, the lifting mechanism raises the electromagnetic chuck close to the item's surface and connects it to the power supply. When the coil inside the electromagnetic chuck is energized, it generates a magnetic field. This magnetic field attracts workpieces with ferromagnetic properties, causing them to adhere firmly to the chuck's surface. To release the workpiece, simply disconnect the power; the magnetic field disappears, and the workpiece can be easily removed. While the chain connection method is sufficiently stable, the electromagnetic chuck remains vertical under gravity. Without operator intervention, it can only be placed on top of the item. To attract the item from the side, the operator must manually hold it, making the operation inconvenient.

[0004] In summary, this utility model provides an intelligent electromagnetic chuck bridge crane to solve the above problems. Utility Model Content

[0021] Example 1

[0022] like Figure 1-5 The image shown is the first embodiment of this utility model, which provides an intelligent electromagnetic chuck bridge crane, comprising:

[0023] The lifting unit 1 includes a bridge crane body 101, a protective box 102 disposed at the bottom of the bridge crane body 101, an electromagnetic chuck body 103 disposed at the bottom of the protective box 102, and a connector 104 disposed at the top of the protective box 102.

[0024] The adjustment unit 2 includes an angle adjustment component 201 disposed in the inner cavity of the protective box 102, and a direction adjustment component 202 disposed on the top of the protective box 102.

[0025] like Figure 1-5 As shown, the bridge crane body 101 supports and connects all other components to realize the overall function of the crane. The protective box 102 protects the internal adjustment mechanism from damage by the external environment. The electromagnetic chuck body 103 uses electromagnetic principles to attract magnetic materials, enabling rapid material lifting. The connector 104 connects the electromagnetic chuck body 103 to the crane's lifting mechanism, enabling the lifting and movement of materials. The angle adjustment component 201 adjusts the operating angle of the electromagnetic chuck body 103, and the direction adjustment component 202 adjusts the operating direction of the electromagnetic chuck body 103. The two components work together to expand the angle that the electromagnetic chuck body 103 can attract, thus eliminating the need for operator assistance and allowing for direct side lifting of items.

[0026] Example 2

[0027] Reference Figure 2 , 3 5, is the second embodiment of this utility model, which is based on the previous embodiment.

[0028] In this embodiment, the angle adjustment component 201 includes a through groove 2011 at the bottom of the protective box 102, a support plate 2012 fixedly connected to the top left side of the inner cavity of the protective box 102, the bottom of the support plate 2012 being movably connected to the top left side of the electromagnetic chuck body 103 via a rotating shaft, and an adjustment plate 2013 disposed on the right side of the support plate 2012, the bottom of the adjustment plate 2013 being movably connected to the top right side of the electromagnetic chuck body 103 via a rotating shaft. Both the support plate 2012 and the adjustment plate 2013 are slidably connected to the inner cavity of the through groove 2011.

[0029] The angle adjustment assembly 201 also includes support blocks 2014 fixedly connected to the top two sides of the inner cavity of the protective box 102, a threaded rod 2015 movably connected between the two support blocks 2014 via bearings, and a threaded sleeve 2016 threadedly connected to the surface of the threaded rod 2015. The top of the adjustment plate 2013 and the bottom of the threaded sleeve 2016 are movably connected via a rotating shaft.

[0030] like Figure 2 , 3 As shown in Figure 5, the through slot 2011 provides more space for the support plate 2012 and the adjusting plate 2013. The support plate 2012 and the adjusting plate 2013 are connected to the electromagnetic chuck body 103 through a rotating shaft to adjust their angle. The structure is simple and easy to adjust, and it can accurately control the adsorption angle of the electromagnetic chuck body 103. The support block 2014, the threaded rod 2015 and the threaded sleeve 2016 constitute a threaded transmission mechanism. By rotating the threaded rod 2015, the threaded sleeve 2016 is driven to move, which in turn drives the adjusting plate 2013 and the electromagnetic chuck body 103 to rotate.

[0031] Example 3

[0032] Reference Figure 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, the angle adjustment assembly 201 further includes a first motor 2017 fixedly connected to the right side of the inner cavity of the protective box 102, the output shaft of the first motor 2017 being drivenly connected to the right end of the threaded rod 2015, a limiting groove 2018 opened at the top of the inner cavity of the protective box 102, and a limiting block 2019 fixedly connected to the top of the threaded sleeve 2016, the top of the limiting block 2019 extending into the inner cavity of the limiting groove 2018 and slidingly connected to its inner cavity.

[0034] The direction adjustment assembly 202 includes a fixed box 2021 fixedly connected to the top of the protective box 102, a second motor 2022 fixedly connected to the left side of the top of the fixed box 2021, a support rod 2023 movably connected to the right side of the fixed box 2021 via a bearing, the top of the support rod 2023 being fixedly connected to the bottom of the connector 104, and a gear 2024 fixedly connected to the surface of the output shaft of the support rod 2023 and the second motor 2022, with the two gears 2024 meshing.

[0035] like Figure 3-5 As shown, the first motor 2017 provides a power source to drive the threaded rod 2015 to rotate. The limiting groove 2018 and the limiting block 2019 work together to limit the movement range of the threaded sleeve 2016 and ensure the safety of angle adjustment. The fixed box 2021 supports and protects the internal components. The second motor 2022 provides a power source to drive the gear 2024 to drive the support rod 2023 to rotate, thereby realizing the direction adjustment of the electromagnetic chuck body 103.

[0036] In normal use, the adjusting plate 2013 is tilted, with its upper end on the left and its lower end on the right. The top of the connecting piece 104 is connected to the lifting mechanism of the bridge crane body 101. The position and height of the electromagnetic chuck body 103 can be controlled through the bridge crane body 101. When vertically lifting items, the AC power is converted to DC power through the thyristor DC box installed in the driver's cab, and then the DC power is supplied through a special cable reel on the trolley structure of the bridge crane body 101. The cable is fed onto the electromagnetic chuck body 103. When the electromagnetic chuck body 103 is energized, it generates magnetic force, attracting magnetically conductive metal objects, thus achieving lifting. When it is necessary to lift an object by adsorption from the side, the first motor 2017 is started first, causing its output shaft to drive the threaded rod 2015 to rotate. As the threaded rod 2015 rotates, it can adjust the position of the threaded sleeve 2016. When the position of the threaded sleeve 2016 changes, it can cooperate with the rotating shaft to adjust the angle of the adjusting plate 2013. Due to the top of the support plate 2012... The upper part is fixed to the inner wall of the protective box 102, and the bottom is connected to the top of the electromagnetic chuck body 103 via a rotating shaft. Therefore, with the cooperation of the support plate 2012 and the bottom rotating shaft of the adjusting plate 2013, the angle of the electromagnetic chuck body 103 can be adjusted. By controlling the downward rotation direction of the output shaft of the first motor 2017, the direction of angle adjustment of the electromagnetic chuck body 103 can be controlled. When the output shaft of the first motor 2017 rotates in the forward direction, the threaded sleeve 2016 moves to the left on the surface of the threaded rod 2015, which allows the electromagnetic chuck body to move to the left. When the output shaft of the first motor 2017 rotates in the reverse direction, the threaded sleeve 2016 moves to the right on the surface of the threaded rod 2015. At this time, the electromagnetic chuck body 103 tilts to the left. Simultaneously, the second motor 2022 can be started. The output shaft of the second motor 2022, in conjunction with two gears 2024, drives the support rod 2023 to rotate, adjusting the direction of the protective box 102, thereby further expanding the angle that the electromagnetic chuck body 103 can attract. After the angle is adjusted, the power is turned on again to lift the item.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
