Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to an electromagnetic suction cup device for suctioning and lifting curved plates. Background Art

[0002] The curved outer plate of the hull (curved plate for short) requires the use of lifting tools for transportation, displacement, positioning and assembly during processing or installation, and lifting tool devices are indispensable.

[0003] Electromagnetic chucks are currently the most commonly used method for lifting curved plates. By switching the power on and off, the magnetic force of the chuck is controlled to achieve the purpose of lifting and transporting the steel plates. The smaller the gap between the chuck and the curved plate, the less magnetic force loss and the greater the suction force, which ensures better safety.

[0004] like Figure 1 As shown, the current adsorption surface of the electromagnetic suction cup is mostly a large plane structure. When adsorbing the curved plate, the gap a between the adsorption surface of the electromagnetic suction cup and the surface of the curved plate is too large. In this case, the suction force will be significantly reduced, which may lead to the inability to suck and lift, or cause it to fall off easily during suction, lifting and transportation, posing a great safety hazard to the suction, lifting and transportation of the curved plate. Summary of the Invention

[0006] The present application provides an electromagnetic suction cup device for lifting a curved plate, comprising at least two magnetic sleeves and a spherical electromagnetic suction cup. After all the magnetic sleeves are assembled into a whole, at least two spherical cavities are formed. The spherical cavity comprises an upper opening and a lower opening. The opening sizes of the upper opening and the lower opening are both smaller than the diameter of the spherical cavity. A lifting lug is also provided on the magnetic sleeve. The spherical electromagnetic suction cup comprises a spherical portion, an adsorption portion and a cable interface. The cable interface is provided on the upper side of the spherical portion for connecting cables, and the lower side of the spherical portion is connected to the adsorption portion as a whole. A spherical electromagnetic suction cup is installed in each spherical cavity. The spherical portion is restricted to move in the spherical cavity. The diameter of the spherical portion is less than or equal to the diameter of the spherical cavity and larger than the opening size of the lower opening. The adsorption portion extends from the lower opening of the spherical cavity, and the cable interface extends from the upper opening of the spherical cavity.

[0007] In one feasible solution, the spherical portion rotates in the spherical cavity so that when the adsorption portion contacts the edge of the lower opening, the cable interface is still within the range of the upper opening.

[0008] In an implementable solution, the diameter of the spherical portion is consistent with the diameter of the spherical cavity; the spherical electromagnetic suction cup also includes a threaded hole and a threaded column; a plurality of threaded holes are provided on the surface of the spherical portion around the cable interface, and the plurality of threaded holes are evenly distributed around the cable interface, and the circumferential distribution formed by the plurality of threaded holes includes at least two circles of different diameters; the threaded column is used to cooperate with the threaded hole, and after the threaded column cooperates with the threaded hole, a predetermined length remains outside the threaded hole.

[0009] In one feasible solution, the diameter of the spherical portion is consistent with the diameter of the spherical cavity; the spherical electromagnetic suction cup also includes at least two annular thread grooves and a thread ring with different diameters; multiple annular thread grooves are opened on the spherical portion, and are all centered on the cable interface; the thread ring is provided with a thread that cooperates with the annular thread groove, and after the thread ring cooperates with the annular thread groove, a predetermined portion of the thread ring still remains outside the annular thread groove.

[0011] In an implementable solution, an anti-sliding block is provided at one end of the threaded rod facing the spherical cavity, and the anti-sliding block is detachably engaged with the end of the threaded rod.

[0012] In one feasible solution, the surface of the anti-slip block is provided with a serrated groove.

[0013] In one feasible solution, a lubrication hole is also provided on the magnetic sleeve, which runs from the inside of the spherical cavity to the outside of the spherical cavity; the lubrication hole is used to add lubricating oil between the inner surface of the spherical cavity and the outer surface of the spherical part, and the lubrication hole is blocked when not in use.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The technical solution of the present application places the adsorption portion of the spherical electromagnetic chuck of the electromagnetic chuck device in contact with the surface of the curved plate when sucking and lifting the curved plate. Based on the degree of curvature of the curved plate, the spherical portion of the spherical electromagnetic chuck adaptively rotates within the spherical cavity, ultimately causing the adsorption surfaces of the adsorption portions of all spherical electromagnetic chucks to conform to the curved plate.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0030] According to the first aspect of this application, Figure 2-6 As shown, first, an electromagnetic suction cup device for lifting a curved plate is provided, comprising at least two magnetic sleeves 10 and a spherical electromagnetic suction cup 20. All the magnetic sleeves 10 are assembled into a whole to form at least two spherical cavities 11. The spherical cavity 11 comprises an upper opening 111 and a lower opening 112. The opening sizes of the upper opening 111 and the lower opening 112 are both smaller than the diameter of the spherical cavity 11. A lifting lug 12 is also provided on the magnetic sleeve 10. The spherical electromagnetic suction cup 20 comprises a spherical portion 21, an adsorption portion 22, and a cable interface 23. The cable interface 23 is provided on the upper side of the spherical portion 21 for connecting cables. The lower side of the spherical portion 21 is integrally connected to the adsorption portion 22. A spherical electromagnetic suction cup 20 is installed in each spherical cavity 11. The spherical part 21 is restricted to move in the spherical cavity 11. The diameter of the spherical part 21 is less than or equal to the diameter of the spherical cavity 11 and larger than the opening size of the lower opening 112. The adsorption part 22 extends from the lower opening 112 of the spherical cavity 11, and the cable interface 23 extends from the upper opening 111 of the spherical cavity 11.

[0031] The technical solution of the above embodiment, when sucking and lifting the curved plate 50, brings the suction portion 22 of the spherical electromagnetic suction cup 20 of the electromagnetic suction cup device into contact with the surface of the curved plate 50. According to the degree of curvature of the curved plate 50, the spherical portion 21 of the spherical electromagnetic suction cup 20 adaptively rotates within the spherical cavity 11, ultimately making the suction surfaces of the suction portions 22 of all spherical electromagnetic suction cups 20 conform to the curved plate 50. Compared to the original electromagnetic suction cup with only one suction surface, the electromagnetic suction cup device of this embodiment achieves better suction and adhesion to the curved surfaces of both sides of the curved plate 50 by using multiple rotatable spherical electromagnetic suction cups 20 (see Figure 2 and Figure 6 ), effectively reducing the gap between the adsorption surface and the surface of the curved plate 50, thereby effectively improving the electromagnetic suction force and electromagnetic adsorption effect, and ensuring the safety of the adsorption and transportation of the curved plate 50.

[0032] In one embodiment, Figure 7 As shown, the spherical portion 21 rotates in the spherical cavity 11 so that when the adsorption portion 22 contacts the edge of the lower opening 112, the cable interface 23 is still within the range of the upper opening 111 to ensure that the cable interface 23 is squeezed by the edge of the upper opening 111 due to the transitional rotation, thereby protecting the cable interface 23 and the connected cable. Figure 7 The angle range on the lower side indicates the rotation angle of the spherical electromagnetic chuck 20. Figure 7 The angle range on the upper side indicates the rotation angle range of the cable interface 23 . It can be seen that the cable interface 23 will never touch the edge of the upper opening 111 .

[0033] In one embodiment, Figure 8 As shown, the diameter of the spherical portion 21 is consistent with the diameter of the spherical cavity 11. The spherical electromagnetic chuck 20 also includes threaded holes 24 and threaded studs 25. Multiple threaded holes 24 are provided on the surface of the spherical portion 21 surrounding the cable interface 23. The threaded holes 24 are evenly distributed around the cable interface 23, and the circumferential distribution of the threaded holes 24 includes at least two circumferences of different diameters. The threaded studs 25 are configured to engage with the threaded holes 24, and after engagement, a predetermined length of the threaded studs 25 remains outside the threaded holes 24. When the threaded studs 25 are assembled in the threaded holes 24, the portion of the threaded studs 25 outside the threaded holes 24 contacts the edge of the upper opening 111, indicating that the rotational angle limit of the spherical portion 21 has been reached. By assembling the threaded studs 25 in the threaded holes 24 of different diameters, the rotational angle limit of the spherical portion 21 can be adjusted. Furthermore, because the threaded studs 25 are positioned a certain distance from the cable interface 23, they protect the cable interface 23 from being squeezed by the edge of the upper opening 111.

[0034] In one embodiment, Figure 9As shown, the diameter of the spherical portion 21 is consistent with the diameter of the spherical cavity 11. The spherical electromagnetic chuck 20 also includes at least two annular thread grooves 26 and a threaded ring 27 of different diameters. Multiple annular thread grooves 26 are formed on the spherical portion 21 and are centered on the cable interface 23. The threaded ring 27 is provided with threads that mate with the annular thread grooves 26. After the threaded ring 27 mates with the annular thread grooves 26, a predetermined portion of the threaded ring 27 remains outside the annular thread grooves 26. The functions of the annular thread grooves 26 and threaded ring 27 are essentially the same as those of the threaded hole 24 and threaded column 25: to limit the rotational range of the spherical portion 21 within the spherical cavity 11. After the threaded ring 27 is matched with the annular thread groove 26, the portion of the threaded ring 27 outside the annular thread groove 26 will limit the further rotation of the spherical portion 21 in the spherical cavity 11 when it touches the edge of the upper opening 111, thereby limiting the rotation angle limit of the spherical portion 21. Because the threaded ring 27 is located at a certain distance from the cable interface 23, the cable interface 23 can be protected from being squeezed by the edge of the upper opening 111.

[0035] In one embodiment, Figure 10 As shown, it also includes a clamping device 30, which includes a threaded channel 31, a threaded rod 32 and a handle 33; the threaded channel 31 is provided on the magnetic sleeve 10 and passes through from the inside of the spherical cavity 11 to the outside of the spherical cavity 11; the threaded rod 32 is provided in the threaded channel 31 and is threadedly engaged with the threaded channel 31; the handle 33 is connected to one end of the threaded rod 32 located outside the spherical cavity 11, and the threaded rod 32 is pressed against the spherical portion 21 inside the spherical cavity 11 by rotating the handle 33, thereby realizing the rotation of the spherical portion 21 in the spherical cavity 11. For a batch of curved plates 50 with the same curvature, the clamping device 30 can be used to fix the relative position of the spherical portion 21 in the spherical cavity 11 after the first suction and lifting, so that the adsorption portion 22 of the spherical electromagnetic suction cup 20 maintains a fixed orientation, which can reduce the number of frictions between the spherical portion 21 and the spherical cavity 11 to a certain extent, and correspondingly improve the service life.

[0036] In one embodiment, Figure 10 As shown, an anti-sliding block 321 is provided at one end of the threaded rod 32 facing the spherical cavity 11. The anti-sliding block 321 is detachably matched with the end of the threaded rod 32. The surface of the anti-sliding block 321 is provided with a serrated groove to achieve a better pressing effect on the spherical part 21.

[0037] In one embodiment, Figure 10As shown, the magnetic sleeve 10 is also provided with a lubrication hole 40, which extends from the interior of the spherical cavity 11 to the exterior of the spherical cavity 11. The lubrication hole 40 is used to apply lubricating oil between the inner surface of the spherical cavity 11 and the outer surface of the spherical portion 21. The lubrication hole 40 is blocked when not in use. The frequent rotation of the spherical portion 21 within the spherical cavity 11 requires lubrication, which also consumes a large amount of lubricant. The lubrication hole 40 allows for timely replenishment of lubricant to ensure smooth rotation of the spherical portion 21 within the spherical cavity 11.

[0038] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
