Description

Technical Field

[0001] This utility model relates to the technical field of metal foil roll transfer devices, specifically to a metal foil roll hook lifting device. Background Technology

[0002] Metal foil rolls, including aluminum foil rolls, undergo multiple production processes, including slitting and cleaning, requiring numerous production equipment and frequent lifting. Careful handling is essential during lifting to minimize damage from impacts that could lead to downgrading, material loss, or scrap, thus ensuring high yield and production efficiency. Aluminum foil rolls are often paired with rollers during production, with the rollers' length exceeding the roll's width for easy winding and transfer. Currently, the transfer process involves ropes passing through the rollers around the foil roll, with both ends connected to an overhead crane for lifting. However, this process is prone to rope swaying or friction with the foil roll, resulting in poor lifting stability.

[0003] The utility model patent with publication number CN222454348U provides an aluminum foil hoisting device, which uses C-shaped support blocks, connecting blocks and lifting frames to fix the aluminum foil roll and then hoist it by a crane. However, its stability is still lacking and its disassembly and assembly are complicated. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal foil roll hooking and lifting device to achieve fast and stable lifting of metal foil rolls.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A metal foil roll hook lifting device includes a trolley, which includes a track and a sliding frame that slides on the track. From top to bottom, a lifting assembly, a rotating assembly, and a frame are sequentially connected to the lower part of the sliding frame. The upper top plate of the lifting assembly is connected to the sliding frame, and the lower bottom plate is connected to the rotating assembly. The rotating assembly allows the frame connected to it to rotate horizontally. Two first hook-shaped components are symmetrically arranged on both sides of the bottom surface of the frame. The distance between the two first hook-shaped components is adjustable. Each first hook-shaped component is rotatably connected to a second hook-shaped component, and the angle between the second hook-shaped component and the first hook-shaped component is adjustable. When the second hook-shaped component rotates to a position where it is in contact with the first hook-shaped component, its length exceeds that of the first hook-shaped component.

[0007] Furthermore, the frame is provided with a sliding groove, and the first hook-shaped component is slidably disposed within the sliding groove via a slider. The slider is connected to an adjusting gear via a rack, and the adjusting gear is connected to the output end of an adjusting motor. The first hook-shaped components located on both sides of the frame are fixedly disposed on the rack or the slider. The racks of the two first hook-shaped components are arranged opposite each other, respectively meshing with the two ends of one diameter of the adjusting gear, so that the two first hook-shaped components move synchronously in opposite directions when driven by the adjusting gear.

[0008] Furthermore, the lifting assembly includes a chain connected to a winch, which is mounted on a sliding frame. The winch or chain is preferably configured as a structure driven by multiple motors working synchronously, and the chain preferably has 6-12 strands.

[0009] Furthermore, the lifting assembly includes a scissor lift frame. The upper and lower ends of one side of the scissor lift frame are hinged to the frame and the sliding frame, respectively. The upper and lower ends of the other side of the scissor lift frame are provided with pulleys. The frame and / or the sliding frame are provided with slots that accommodate the pulleys. The pulleys slide along the slots when the scissor lift frame is in operation. These slots ensure that the hinged end of the scissor lift frame remains at the same height as the pulley-slot during the deformation and lifting process.

[0010] Furthermore, the second hook-shaped component is hinged to an adjusting block, and a worm gear is rotatably mounted inside the adjusting block. The worm gear is connected to the output end of a worm gear motor, and a worm is meshed with the worm. One end of the worm is hinged to the first hook-shaped component, and the length of the second hook-shaped component is greater than the length of the first hook-shaped component. Specifically, one end of the worm is rotatably connected to the first hook-shaped component. A trapezoid is constructed using four points: the hinge point between the worm and the first hook-shaped component, the hinge point between the second hook-shaped component and the first hook-shaped component, the hinge point between the second hook-shaped component and the adjusting block, and the worm gear. The first hook-shaped component and the second hook-shaped component can be considered as one leg and the lower base of the trapezoid, respectively. The movement of the worm gear on the worm can be considered as adjusting the length of the upper base of the trapezoid. The coordinated movements of each hinge point force a change in the angle between the first hook-shaped component and the second hook-shaped component of the trapezoid.

[0011] Furthermore, the second hook-shaped component is rotatably mounted on the first hook-shaped component via a connecting bend plate. The first hook-shaped component and the second hook-shaped component are located on the same side of the frame and are mounted on the same side of the connecting bend plate. The first hook-shaped component and the second hook-shaped component have the same thickness. When the connecting bend plate rotates the second hook-shaped component to a vertical position, it partially fits into the first hook-shaped component.

[0012] Furthermore, a rotating component is also provided between the lifting component and the frame. The rotating component includes a driven gear fixedly connected to the frame on one side. The driven gear is meshed with a transmission gear. The transmission gear is connected to the output end of a rotary motor. The rotary motor is fixedly mounted on the sliding frame by a fixing plate. A rotating shaft is also provided between the fixing plate and the driven gear. The transmission gear drives the driven gear to rotate along the rotating shaft.

[0013] Furthermore, the crane is equipped with a crane motor, and the crane motor, winch, regulating motor, worm gear motor and rotary motor are preferably servo motors, with at least one of them electrically connected to the industrial control board.

[0014] Furthermore, the industrial control board is connected to a remote control.

[0015] Furthermore, the contact surfaces of the first hook-shaped component and / or the second hook-shaped component with the aluminum foil roller are detachably provided with buffer blocks.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, after the first hook-shaped component is sent to the aluminum foil roll below by the crane and lifting assembly, the first hook-shaped component can hook the two ends of the roller around which the metal foil roll is surrounded. Then, after the frame is raised, the aluminum foil roll is hoisted and transferred by the crane. The first hook-shaped component is connected to the roller to avoid direct contact with the metal foil roll. The hook-shaped component has higher rigidity than the rope, which makes the hoisting process more stable and is suitable for the crane travel route set at an incline.

[0018] 2. This utility model features a sliding groove on the frame. A slider within the groove limits the relative rotation of the first hook-shaped component. By adjusting the meshing relationship of the gears and racks, the relative distance between the hook-shaped components on both sides can be adjusted, thus adapting to the hoisting of rollers and aluminum foil rolls of different lengths. The lifting assembly uses a winch for power output. The winch works in conjunction with a scissor lift frame. One end of the scissor lift frame is hinged to the frame, and the other end is limited to horizontal movement via a slotted pulley, thereby reducing the overall sway of the device.

[0019] 3. The second hook-shaped component can be rotated vertically by a worm gear. By connecting the bent plate, the distance between it and the two first hook-shaped components on the left and right is equal, and the final position of rotation is when it is in contact with the first hook-shaped component. The hook of the second hook-shaped component can be selected to have a different radius than the first hook-shaped component, so as to adapt to various specifications of metal foil rolls.

[0020] 4. The remote control, which is electrically connected to the industrial control board, allows the operator to control the operation of the entire device from the ground, with high precision and high efficiency. Attached Figure Description

[0039] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0040] Example 1

[0041] Please see Figures 1-10 The metal foil roll hook lifting device of this embodiment includes a traveling trolley 1, a lifting assembly 2, a rotating assembly 7, and a frame 3. A sliding frame 12 is slidably mounted on the track 11 of the traveling trolley 1, and the sliding frame 12 is driven by the traveling trolley motor to move along the track. The upper top plate of the lifting assembly 2 is fixedly connected to the sliding frame 12, and the lower bottom plate is connected to the winch 22 via a chain 21. When the winch 22 retracts or extends the chain 21, it drives the lower bottom plate and the connected frame 3 to rise and fall vertically. The bottom sides of the frame 3 are provided with sliding grooves 31, and the first hook-shaped component 4 slides along the sliding groove via a slider 32. The slider 32 is fixed with a rack 34, and the two racks 34 are symmetrically engaged with the two sides of the adjusting gear 33, which is driven by an adjusting motor 35. When the adjusting gear 33 rotates, the two first hook-shaped components 4 move synchronously in opposite directions to adapt to foil rolls of different widths. The second hook-shaped component 6 is hinged to the first hook-shaped component 4 via a connecting bent plate 5. The design of the connecting bent plate 5 allows the second hook-shaped component 6 to rotate vertically around the hinge point and partially engage with the first hook-shaped component 4 in the vertical position. The rotation of the second hook-shaped component 6 is driven by a worm gear 62 and a worm 64. The worm gear motor 63 drives the adjusting block to move on the worm 64 via the worm gear 62, thereby adjusting the angle of the second hook-shaped component. The driven gear 71 of the rotating assembly 7 is fixed to the frame 3, and the transmission gear 72 is driven by a rotary motor 73. The rotary motor 73 is fixedly connected to the sliding frame 12 via a fixing plate 74. The rotary motor 73 drives the driven gear 71 and its fixedly connected frame 3 and hook-shaped component to rotate horizontally around the rotating shaft 75, facilitating the adjustment of the hooking direction. The trolley motor, winch 22, adjusting motor 35, worm gear motor 63, and rotary motor 73 are all electrically connected to the industrial control board. The industrial control board is connected to a remote control via a wireless communication module for remote operation. The contact surfaces of the first hook-shaped component 4 and the second hook-shaped component 6 with the metal foil roll roller are provided with rubber buffer blocks 8, which are detachable by bolts to prevent damage to the surface of the foil roll during hooking.

[0042] During operation, the operator uses a remote control to move the overhead crane 1 above the aluminum foil roll, lowers the frame 3 so that the first hook-shaped component 4 engages with both ends of the roller, and then raises the frame 3 and transports it to the target position. This design significantly improves lifting stability by replacing traditional soft slings with rigid hooks. This embodiment can also be adapted to inclined track scenarios by adjusting the crane's power.

[0043] Example 2

[0044] Please see Figures 1-4Based on Embodiment 1, this embodiment further improves the lifting assembly. The lifting assembly 2 adopts a combination structure of winch 22 and scissor lift frame 23: the upper and lower ends of one side of the scissor lift frame 23 are hinged to the frame 3 and the sliding frame 12 respectively, and the upper and lower ends of the other side are respectively embedded in the slots 25 fixedly set by the frame and the sliding frame through pulleys 24. When lifting, the pulleys 24 slide horizontally along the slots 25. During the unfolding and retraction of the scissor lift frame 23, it is pulled by the winch chain 21, and the double limit reduces the shaking.

[0045] Example 3

[0046] Please see Figures 1-4 The difference between this embodiment and Embodiment 1 is that the lifting assembly adopts a hydraulic drive structure. A hydraulic cylinder (not shown in the figure) is connected to the central hinge of the scissor lift frame 23. The cylinder body of the hydraulic cylinder is fixed on the sliding frame 12, and the piston rod end is hinged to the intersection of the scissor arms. When the hydraulic cylinder extends or retracts, it drives the scissor arms to open or close, thereby driving the frame 3 to rise or fall. The chain 21 is replaced by a rigid guide post. The upper end of the guide post slides with the sliding frame 12, and the lower end is fixed to the frame 3 to ensure no swaying during the lifting process. The adjustment mechanism of the first hook-shaped component 4 uses a double-ended screw instead of a gear and rack. The two ends of the screw rotate in opposite directions and are driven to rotate by the adjustment motor 35, so that the two sides of the first hook-shaped component 4 move synchronously in opposite directions. The adjustment block 61 of the second hook-shaped component 6 is equipped with an electric push rod. One end of the push rod is hinged to the middle of the worm gear 64, and the other end is hinged to the inner wall of the adjustment block 61. The opening and closing angle of the second hook-shaped component is changed by extending or retracting the push rod. In this embodiment, the hydraulic cylinder needs to be selected to be suitable for heavier metal foil rolls, and the influence of the hydraulic cylinder's own weight also needs to be considered separately.

[0047] Example 4

[0048] Please see Figures 1-5 This embodiment expands the hook's functionality based on Embodiment 2. A second hook-shaped component 6 is hinged to the outer side of the first hook-shaped component 4 via a connecting curved plate 5. The second hook-shaped component 6 is approximately 30-60 cm longer than the first hook-shaped component 4. A worm gear 62 is rotatably mounted at the tail of the second hook-shaped component 6. The worm gear 62 meshes with a worm 64 driven by a worm gear motor 63, allowing the second hook-shaped component 6 to rotate within an angle range of at least 0-90° around its hinge point with the first hook-shaped component 4. When the second hook-shaped component 6 rotates to a vertical position around its hinge point with the first hook-shaped component 4, its connecting part is parallel and close to the first hook-shaped component 4, allowing it to hook smaller diameter rollers. Both the first hook-shaped component 4 and the second hook-shaped component 6 are located on the same side of the connecting curved plate 5, with consistent width on both sides, and the first and second hook-shaped components on the same left or right side avoid interference.

[0049] Example 5

[0050] This embodiment is optimized for special working conditions. The hook surface of the second hook-shaped component 6 has a dovetail groove to accommodate a polyurethane buffer block 8, which can be quickly replaced by bolts. The frame 3 has a built-in tilt sensor connected to the industrial control board to monitor the lifting posture in real time. When the tilt angle exceeds the limit, an alarm is triggered and the motor is locked. This design is suitable for high-precision lifting and vibration-sensitive environments, further improving safety and adaptability.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
