Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a coil lifting device. Background Technology

[0002] In industrial fields such as motor manufacturing and transformer production, coils are core components, and their handling and hoisting operations run through the entire product production process. Whether it is a micro coil for a small household motor or a giant coil for a large power transformer, the daily hoisting frequency can reach dozens or even hundreds of times, and the characteristics of the coil itself place extremely high demands on the hoisting operation.

[0003] In existing industrial production processes, coil lifting tools typically use lifting beams and hooks to lift coils. However, most existing coil lifting tools are fixed structures and can only lift coils of the same type. In the manufacturing process of motors and transformers, coils of various models and sizes are used. Existing lifting tools have poor versatility and cannot meet the lifting needs of various types of coils, which is quite inconvenient.

[0004] Therefore, a coil lifting tool with strong versatility has been developed that can adjust the position of the lifting feet and the angle between multiple lifting feet to adapt to the lifting needs of different models of coils. Summary of the Invention

[0005] To overcome the shortcomings of existing coil lifting tools, which are mostly fixed structures, have poor versatility, cannot meet the lifting needs of various types of coils, and are inconvenient, the technical problem to be solved is: to provide a coil lifting tool that can adjust the position of the lifting feet and the angle between multiple lifting feet, adapt to the lifting needs of different models of coils, and has strong versatility.

[0006] The technical solution of this utility model is as follows: a coil lifting device includes a lead screw, a bevel gear set, a first motor, a support frame, a rotating plate, a second motor, a support block, a distribution box, a fixed plate, and a lifting assembly. The support block is equipped with a distribution box, and the second motor is connected inside the support block. The fixed plate is connected to the lower side of the support block, and the rotating plate is rotatably connected to the fixed plate. Support frames are connected to the left and right sides of the upper part of the rotating plate, and support frames are also connected to the front and rear sides of the upper part of the fixed plate. The first motor is connected to each support frame. Lead screws are rotatably connected to the upper left and right sides of the rotating plate, and lead screws are also rotatably connected to the upper front and rear sides of the fixed plate. Each lead screw is connected to a bevel gear set between it and the output shaft of the adjacent first motor. The fixed plate and the rotating plate are equipped with a lifting assembly capable of lifting the coil.

[0007] In one embodiment, a protective cover is provided on the outside of the bevel gear set.

[0008] In one embodiment, the hoisting assembly includes a base, a tie rod, a locking block, a hoisting plate, a lifting rod, a first electric telescopic rod, a connecting frame, rollers, and a movable block. Each lead rod is threadedly connected to a movable block, and each movable block is connected to a connecting frame. Each connecting frame is connected to a roller. Rollers on the fixed rod are in rolling engagement with the fixed rod, and rollers on the rotating rod are in rolling engagement with the rotating rod. Each connecting frame contains a first electric telescopic rod, and each telescopic end of the first electric telescopic rod is connected to a lifting rod. Each lifting rod is slidably connected to an adjacent connecting frame. Each lifting rod is connected to a base, and a hoisting plate is placed on each base. Each connecting frame is slidably engaged with a locking block, and each locking block is connected to a tie rod. Each locking block is engaged with an adjacent hoisting plate.

[0009] In one embodiment, the foot plate is provided with multiple adjustment holes.

[0010] In one embodiment, the end of the footplate is tapered.

[0011] In one embodiment, the system further includes a second electric telescopic rod and a pressure block. The second electric telescopic rod is connected to the connecting frame, and the telescopic end of the second electric telescopic rod is connected to a pressure block.

[0012] The beneficial effects are: by starting the first motor to rotate the lead screw, the horizontal position of the lifting foot plate can be adjusted; by starting the second motor, the rotating plate can rotate on the fixed plate, and the included angle between the lifting foot plates can be adjusted. This achieves the effect of being able to adjust the position of the lifting foot plates and the angle between multiple lifting foot plates, adapting to the lifting needs of different models of coils, and having strong versatility.

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] A coil lifting device, such as Figures 1-4 As shown, the assembly includes a lead screw 11, a bevel gear set 12, a first motor 13, a support frame 14, a rotating plate 15, a second motor 16, a support block 17, a distribution box 18, a fixing plate 19, and a hoisting assembly. The distribution box 18 is mounted on the support block 17, and the second motor 16 is connected inside the support block 17. The fixing plate 19 is connected to the lower side of the support block 17, and the rotating plate 15 is rotatably connected to the fixing plate 19. The left and right sides of the upper part of the rotating plate 15 are connected to the support frame 14, and the front and rear sides of the upper part of the fixing plate 19 are also connected to the support frame 14. The first motor 13 is connected to each of the support frames 14. The lead screw 11 is rotatably connected to the upper left and right sides of the rotating plate 15, and the lead screw 11 is rotatably connected to the upper front and rear sides of the fixing plate 19. The lead screw 11 is connected to the output shaft of the adjacent first motor 13 by a bevel gear set 12. The bevel gear set 12 is provided with a protective cover on its outer side. The fixing plate 19 and the rotating plate 15 are equipped with a hoisting assembly.

[0020] like Figure 1 and Figure 2 As shown, the hoisting assembly includes a base 1, a tie rod 2, a locking block 3, a hoisting plate 4, a lifting rod 5, a first electric telescopic rod 6, a connecting frame 7, rollers 71, a second electric telescopic rod 8, a pressure block 9, and a moving block 10. Each lead screw 11 is threadedly connected to a moving block 10, and each moving block 10 is connected to a connecting frame 7. Each connecting frame 7 is connected to a roller 71. The rollers 71 on the fixed rods are in rolling engagement with the fixed rods, and the rollers 71 on the rotating rods are in rolling engagement with the rotating rods. Each connecting frame 7 contains a first electric telescopic rod 6. The first electric telescopic rod 6 is connected to a lifting rod 5 at its telescopic end. The lifting rod 5 is slidably connected to the adjacent connecting frame 7. The lower side of the lifting rod 5 is connected to a foot 1. The foot 1 is placed on a hanging plate 4. The connecting frame 7 is slidably engaged with a locking block 3. The locking block 3 is connected to a pull rod 2. The locking block 3 is engaged with the adjacent hanging plate 4. The hanging plate 4 is provided with five adjustment holes. The end of the hanging plate 4 is obliquely conical. The connecting frame 7 is connected to a second electric telescopic rod 8. The telescopic end of the second electric telescopic rod 8 is connected to a pressure block 9.

[0021] When using this invention, the support block 17 is first connected to the crane's steel cable. The crane then controls the movement of this device. When the coil needs to be hoisted, the crane can move the lifting feet 4 below the coil to be hoisted. After the four lifting feet 4 are inserted under the coil, the coil can be hoisted. During the coil hoisting process, the second electric telescopic rod 8 can be activated, causing its telescopic end to extend and the pressure plate to move downwards, thus stabilizing the coil and maintaining its hoisting stability. By activating the first electric telescopic rod 6, the height of the lifting rod 5 can be adjusted simultaneously and independently, thereby adjusting the height of the lifting feet 4 to accommodate coils of different thicknesses. By sliding the locking block 3 upwards on the base foot 1 using the pull rod 2, the height of the lifting feet 4 can be adjusted. After extending the length and adjusting, press the pull rod 2 to re-engage the locking block 3 into the lifting foot plate 4, thus fixing the lifting foot plate 4. By starting the first motor 13, the lead screw 11 can be rotated through the transmission of the bevel gear. Under the action of the thread, the connecting frame 7 can slide, and the roller 71 can slide on the rotating plate 15 or the fixed plate 19, which can adjust the position of the connecting frame 7 individually or simultaneously, thereby adjusting the horizontal position of the lifting foot plate 4. By starting the second motor 16, the rotating plate 15 can be rotated on the fixed plate 19, which can adjust the angle between the lifting foot plate 4 on the fixed plate 19 and the lifting foot plate 4 on the rotating plate 15. This allows for adjustment of the position of the lifting foot plate 4 and the angle between multiple lifting foot plates 4, adapting to the needs of different coil hoisting models and providing strong versatility.
