Description

Technical Field

[0001] This application relates to the field of hoisting equipment technology, specifically to a special device for hoisting sheet metal, which is particularly suitable for stable clamping operations of sheet metal of different sizes during handling and hoisting. Background Technology

[0002] Lifting operations are an indispensable part of the production, processing and transportation of sheet materials. However, existing sheet material lifting methods have many problems and cannot meet the needs of efficient and safe lifting of sheet materials of different sizes in actual production.

[0003] Currently, there are some general-purpose lifting equipment on the market, such as ordinary hooks and clamps. Although these devices have a certain degree of versatility, they have obvious limitations in lifting sheet metal.

[0004] 1. Unstable clamping: General-purpose hooks can only simply bind the plates with ropes or slings, which cannot provide a stable clamping force. During the lifting process, the plates are prone to slipping due to shaking, resulting in unstable lifting posture and increasing the risk of lifting operations.

[0005] 2. Inability to adapt to different sizes of boards: General-purpose lifting clamps and other equipment generally have fixed dimensions and clamping ranges, making it difficult to adjust according to the actual size of the board. For boards of different widths and thicknesses, general-purpose lifting clamps may not be able to provide suitable clamping force, resulting in insecure clamping or damage to the surface of the board. Utility Model Content

[0006] The problem this application aims to solve is the unstable clamping and inability to adapt to different sizes of plates in existing plate hoisting technologies.

[0007] To address the aforementioned technical problems, this application provides a lifting clamping device for sheet metal, comprising: a frame, horizontally positioned below the electric hoist of a crane, with symmetrically arranged booms connected to the electric hoist at both ends along its length; an adjustable clamping assembly, symmetrically arranged at both ends along the length of the frame, capable of actively adjusting the clamping distance according to the length or width of the sheet metal, comprising: guide rods symmetrically arranged on both sides of the frame in the width direction; support sleeves, spaced apart along the axial direction of the guide rods and connected to the frame; support rods, horizontally arranged below the guide rods; sliding sleeves, spaced apart along the circumferential direction of the guide rods and connected to the support rods; and a clamping assembly, arranged side-by-side at both ends along the width direction below the adjustable clamping assembly, capable of adaptively adjusting the clamping distance according to the thickness of the sheet metal, comprising: a rod seat welded to one end of the support rod; a clamping wheel arranged on one side of the rod seat, with a bearing sleeved at its axial position; and a wheel plate arranged between the clamping wheel and the rod seat, and connected to the rod seat and the clamping wheel respectively by bolts.

[0008] Furthermore, the pitch adjustment assembly also includes a first motor arranged inside the frame; a gear arranged at the end of the first motor and keyed thereto; and a rack arranged at the top of the strut and meshing with the gear.

[0009] Furthermore, the clamping rollers include a support roller, which is arranged in the lower half of the rod base and abuts against the bottom surface of the plate; a pressure roller, which is arranged in the upper half of the rod base and abuts against the top surface of the plate; and a support roller, which is arranged in the middle of the rod base and abuts against the side of the plate.

[0010] Furthermore, a sliding rod connected to the wheel plate is arranged at the top of the pressure roller.

[0011] Furthermore, a compression spring is fitted around the outside of the slide bar to abut against the rod seat.

[0012] Furthermore, the strut has an L-shaped structure that facilitates connection with the strut sleeve and strut seat.

[0013] Furthermore, the rod holder has a T-shaped structure that facilitates the installation of the support roller, pressure roller, and support roller.

[0014] Furthermore, the upper part of the strut is equipped with a drive component that can drive the strut wheel to rotate, thereby adjusting the relative position of the plate and the frame, so that the center of gravity of the plate is relatively centered.

[0015] Furthermore, the drive assembly includes a base fixedly arranged on one side of the support rod; a second motor fixedly arranged on the upper part of the base; a first pulley respectively arranged on the shaft end of the second motor and on one side of one of the support pulleys; and a belt sleeved on the outside of the first pulley.

[0016] Furthermore, the drive assembly includes a second pulley, which is fixedly arranged on the outside of the two support pulleys; and a timing belt, which is sleeved on the outside of the second pulley.

[0017] Because the clamping device of this application is designed with an adjustable clamping component and a clamping component, it can actively adjust the clamping distance according to the length or width of different sized plates, and adaptively adjust the clamping distance according to the thickness of different sized plates. This solves the problems of unstable clamping and inability to adapt to different sized plates in the existing plate hoisting technology.

[0018] The technical effects of the technical solution in this application are as follows:

[0019] 1. Adaptability to different sheet sizes: The adjustable spacing assembly enables adaptation to sheet sizes of different dimensions. The guide rod, support sleeve, support rod, sliding sleeve, first motor, gear, and rack work together in the adjustable spacing assembly. The first motor drives the gear to rotate, and the gear meshes with the rack, thereby driving the support rod to move along the axial direction of the guide rod. The operator can precisely control the forward and reverse rotation of the first motor according to the width of the sheet to be lifted, and adjust the spacing between the support rods. This design allows the lifting device to flexibly adapt to sheet sizes of different widths. Whether it is a narrow decorative sheet or a wide building sheet, it can achieve stable clamping, which greatly improves the versatility and practicality of the device.

[0020] 2. Stable Clamping of Panels: The clamping assembly uses a combination of support rollers, pressure rollers, and support rollers to clamp the panels from all directions. The support rollers support the bottom surface of the panels to prevent them from falling; the pressure rollers press against the top surface of the panels, working in conjunction with the support rollers to clamp them tightly; the support rollers abut against the sides of the panels to further enhance the clamping effect. The clamping rollers are connected by bearings and bolts, allowing them to rotate freely. This greatly reduces the friction between the clamping rollers and the panels, preventing damage to the panel surface during hoisting. At the same time, this all-around clamping method ensures that the panels are subjected to uniform force during hoisting, effectively preventing the panels from shaking and slipping, and ensuring the stability of the clamping.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0033] This embodiment provides a lifting device for sheet metal. This device is mainly used during the handling and lifting of sheet metal to achieve stable clamping and correction of sheet metal of different sizes, thereby improving the safety and efficiency of the lifting operation. Figure 1-4 As shown, the lifting device includes a horizontally placed frame 1, which serves as the basic support structure for the entire lifting device. Symmetrically arranged at both ends of the frame 1 are upward-extending, triangular-shaped booms. This triangular design of the booms enhances their structural strength and increases their load-bearing capacity. The ends of the booms are connected to the electric hoists of the overhead crane, which provide lifting power to enable the lifting and movement of the entire lifting device.

[0034] Below the frame 1, at both ends along the length direction, there are symmetrically arranged adjustable spacing components 2, which can adjust the clamping distance according to the size of the plate. The function of the adjustable spacing components 2 is to adjust the distance between the clamping components 3 on both sides according to the width of the plate to be hoisted, so as to ensure that the clamping components 3 can accurately clamp the plate. Below the adjustable spacing components 2, at both ends along the width direction, there are clamping components 3 that can clamp plates of different thicknesses. The clamping components 3 can directly contact the plate and provide stable clamping for plates of different thicknesses through adaptive adjustment.

[0035] The pitch adjustment assembly 2 includes a guide rod 21, a support sleeve 22, a support rod 23, a sliding sleeve 24, a first motor 25, a gear 26, and a rack 27. The guide rod 21 is symmetrically arranged on both sides of the frame 1 in the width direction, providing guidance for the movement of the support rod 23. The support sleeves 22 are spaced apart along the axial direction of the guide rod 21 and are connected to the frame 1 by bolts. The support sleeves 22 serve to fix the guide rod 21 and support the support rod 23. The support rod 23 is arranged below the guide rod 21 and has an L-shaped structure. This structure facilitates connection with the clamping assembly 3 and can stably support the clamping assembly 3 during pitch adjustment. The upper part of the support rod 23 is provided with a sliding sleeve 24 connected to it by bolts. The upper end of the sliding sleeve 24 is connected to the guide rod 25. The support rods 23 are arranged in a nested manner and can slide back and forth along the surface of the guide rod 21, thereby realizing the movement of the support rod 23 along the axial direction of the guide rod 21. The first motor 25 is arranged inside the frame 1, and the end of the first motor 25 is provided with a gear 26 connected to it by a key. The rack 27 is arranged on the top of the support rod 23 by bolts and meshes with the gear 26. When the first motor 25 drives the gear 26 to rotate, due to the meshing relationship between the gear 26 and the rack 27, the rack 27 will drive the support rod 23 to move back and forth along the axial direction of the guide rod 21, thereby changing the clamping distance between the support rods 23. By controlling the forward and reverse rotation of the first motor 25, the position of the support rod 23 can be precisely adjusted to adapt to plates of different widths.

[0036] The clamping assembly 3 includes a rod base 31, a clamping wheel 32, and a wheel plate 33. The rod base 31 is T-shaped and welded to one end of the lower part of the support rod 23. The rod base 31 provides a stable mounting base for the clamping wheel 32. The clamping wheel 32 for clamping and fixing the plate is arranged on the rod base 31. The wheel plate 33 is arranged between the clamping wheel 32 and the rod base 31 and is connected to the clamping wheel 32 and the rod base 31 respectively by bolts. Since the clamping wheel 32 is also fitted with a bearing between it and the bolt, the clamping wheel 32 can rotate freely. This can reduce the friction between the clamping wheel 32 and the plate and avoid damage to the surface of the plate during hoisting.

[0037] The clamping rollers 32 are divided into support rollers 321, pressure rollers 322, and support rollers 323 according to their arrangement. The support rollers 321 are arranged in the lower half of the rod base 31, and their main function is to support the bottom surface of the plate and prevent the plate from falling during hoisting. The pressure rollers 322 are arranged in the upper half of the rod base 31 and are used to press the top surface of the plate. They work with the support rollers 321 to clamp the plate. The support rollers 323 are arranged in the middle of the rod base 31 and are used to abut against the side of the plate to further enhance the clamping effect of the plate. They can also correct the offset of the plate during hoisting and ensure that the plate maintains a stable posture. In order to make the plate stably arranged between the clamping rollers 32, the top of the pressure roller 322 is provided with a sliding rod 324 connected to the wheel plate 33. A compression spring 325 is sleeved on the outside of the sliding rod 324 and abuts against the rod base 31. The compression spring 325 helps the pressure roller 322 to adapt to plates of different thicknesses.

[0038] Working principle: In actual use, firstly, according to the size of the plate to be lifted, the first motor 25 is started. The first motor 25 drives the gear 26 to rotate. The gear 26, through meshing with the rack 27, drives the support rod 23 to move along the axial direction of the guide rod 21. The distance between the two support rods 23 is adjusted so that the clamping component 3 can accurately correspond to the position of the plate. Then, the plate is placed on the support roller 321. Through the action of the pressure roller 322 and the support roller 323, the plate is stably clamped. Finally, the lifting device and the plate are lifted together by the electric hoist of the overhead crane. During the lifting process, the clamping component 3 can perform clamping operation on the plate in real time to ensure that the plate is safely and stably lifted.

[0039] Instructions for use: Before using the lifting device, a comprehensive inspection of the entire device is required. Check whether the boom connection is secure and ensure that there is no looseness or wear at the connection point with the electric hoist. Check whether the guide rod 21 in the adjusting assembly 2 is smooth and whether the support sleeve 22, sliding sleeve 24, and other components are damaged. Check whether the clamping wheel 32 of the clamping assembly 3 rotates flexibly and whether the bolt connection is tight. At the same time, check whether the electrical system of the first motor 25 and the electric hoist is normal, ensuring that the power supply is stable and the control switch is sensitive. Then, measure the length, width, and thickness of the plate to be lifted. Determine the required adjustment distance of the adjusting assembly 2 based on the width of the plate and select the appropriate lifting parameters of the electric hoist based on the weight of the plate.

[0040] The hoisting device is then moved to a suitable position above the plate to be hoisted. The power supply of the first motor 25 is turned on, and the first motor 25 is started by the control switch. According to the pre-measured width of the plate, the forward and reverse rotation of the first motor 25 is controlled, so that the gear 26 drives the rack 27 to move, which in turn drives the support rod 23 to move along the axial direction of the guide rod 21. The change in the spacing between the support rods 23 is observed. When the spacing between the support rods 23 is adjusted to be slightly larger than the width of the plate, the first motor 25 is stopped. At this time, the spacing adjustment component 2 completes the spacing adjustment and is ready to clamp the plate.

[0041] Using auxiliary tools (such as forklifts, trolleys, etc.), slowly move the plate to be lifted above the support roller 321 of the clamping assembly 3, so that the bottom surface of the plate is in full contact with the support roller 321. Operate the overhead electric hoist to slowly lower the lifting device. Apply pressure to the top surface of the plate through the pressure roller 322, while the support roller 323 abuts against the side of the plate. Under the action of pressure, the support roller 321, pressure roller 322 and support roller 323 cooperate with each other to form a stable clamp on the plate. At this time, the clamping roller 32 can rotate freely and will automatically adjust according to the position of the plate to ensure that the clamping force is evenly distributed.

[0042] After confirming that the plate is clamped stably, the hoisting device is slowly lifted by the overhead crane to lift the plate off the ground. During the lifting process, the condition of the plate and the operation of the hoisting device are closely observed to ensure that the plate does not shake or shift. The overhead crane is controlled to move the hoisting device and the plate together to the designated position. During the movement, the clamping component 3 will continuously clamp and correct the plate to ensure that the plate always maintains a stable posture.

[0043] When the hoisting device is moved above the designated position, the overhead electric hoist is slowly lowered to accurately place the sheet metal in the target position. During the placement process, the descent speed is carefully controlled to avoid collision between the sheet metal and the ground or other objects. After the sheet metal is placed, the first motor 25 is restarted to move the support rod 23 to both sides to increase the clamping distance and release the clamp on the sheet metal. Then, the hoisting device is raised to a suitable height and moved to the storage position to complete the hoisting operation.

[0044] The hoisting device in this embodiment, through the coordinated action of the adjusting component 2 and the clamping component 3, can achieve stable clamping operation on plates of different sizes. It has the advantages of simple structure, convenient operation and wide applicability, and can be widely used in the hoisting operation of plates. Example

[0045] Based on Example 1, this embodiment addresses the issue that the plate may not be centered in the frame 1 when clamped, causing the plate to shift at an angle during hoisting due to its center of gravity not being centered, which in turn makes the plate prone to falling and collisions during unloading. A drive component 4 is added to the upper part of the support rod 23 to drive the support wheel 323 to rotate, thereby adjusting the relative position of the plate and the frame 1 and making the center of gravity of the plate relatively centered.

[0046] like Figure 5-6 As shown, the drive assembly 4 includes a base 41, a second motor 42, a first pulley 43, a belt 44, and a synchronous belt 46. The base 41 is fixed to one side of the support rod 23 by bolts. The second motor 42, which provides driving force, is fixed to the upper part of the base 41 by bolts. The shaft end of the second motor 42 and one of the support wheels 323 are both connected by a key to the first pulley 43. The belt 44, which plays a transmission role, is sleeved between the first pulleys 43. In order to improve the driving effect between the support wheel 323 and the plate and to avoid slippage due to insufficient contact area, a second pulley 45 is also connected by a key between the two support wheels 323. The second pulley 45 is sleeved with a synchronous belt 46 to realize the synchronous rotation operation of the two support wheels 323. In turn, by increasing the friction with the side of the plate, the plate is driven to perform horizontal position adjustment operation so that the center of gravity of the plate is relatively centered.

[0047] Working principle: When the plate is not centered during clamping, the operator starts the second motor 42 in the drive assembly 4. The rotation of the second motor 42 drives the first pulley 43 at the shaft end to rotate. The first pulley 43 drives another first pulley 43 to rotate through the belt 44. The first pulley 43 is keyed to the support wheel 323, thereby driving the support wheel 323 to rotate. At the same time, since the two support wheels 323 are connected by the second pulley 45 and the synchronous belt 46, the synchronous rotation of the two support wheels 323 is achieved. When the support wheel 323 rotates, it generates friction with the side of the plate. This friction will drive the plate to move horizontally, thereby adjusting the relative position of the plate and the frame 1, so that the center of gravity of the plate gradually moves closer to the center position of the frame 1.

[0048] During the hoisting process, the operator can activate the drive assembly 4 in a timely manner according to the offset of the plate to adjust the position of the plate. For example, when it is found that the plate is tilted to one side, the drive assembly 4 is activated to rotate the support wheel 323, which drives the plate to move in the opposite direction until the plate is in a relatively centered position. This can effectively prevent the plate from shifting at an angle due to the center of gravity not being centered, reduce the risk of the plate falling and bumping during the drop, and improve the safety and accuracy of the hoisting operation.

[0049] Instructions for use: In addition to the equipment inspection items in Example 1, it is also necessary to focus on inspecting the drive assembly 4, checking whether the second motor 42 is securely fixed, whether the key connections between the first pulley 43, the second pulley 45 and the shaft end of the second motor 42 and the support wheel 323 are reliable, and whether the belt 44 and the synchronous belt 46 are worn or loose, etc., to ensure that all components of the drive assembly 4 can operate normally. Place the plate to be hoisted in the predetermined position and prepare to use the hoisting device for clamping. According to the method in Example 1, operate the distance adjustment assembly 2 to adjust the distance between the support rods 23, and then use the clamping assembly 3 to clamp the plate. During the clamping process, observe the position of the plate and make a preliminary judgment on whether the plate is roughly centered.

[0050] If the plate is found to be significantly biased to one side during clamping, the drive assembly 4 can be started immediately after clamping is completed for fine-tuning. The power supply of the second motor 42 in the drive assembly 4 is turned on, and the second motor 42 is controlled to rotate forward and backward according to the offset direction of the plate. For example, if the plate is biased to the left, the second motor 42 is started to rotate the support wheel 323 clockwise. The friction between the support wheel 323 and the side of the plate drives the plate to move to the right, and the position of the plate is initially adjusted.

[0051] During the process of the overhead crane hoist slowly lifting the lifting device to lift the plate off the ground, the operator must closely observe the condition of the plate. If any signs of angular displacement are found, such as a slight tilt or leaning to one side at one end of the plate, the lifting operation should be stopped immediately. According to the direction of the plate's displacement, the second motor 42 in the drive assembly 4 should be started. If the plate is tilted to the right, the second motor 42 should be started to rotate the support wheel 323 counterclockwise. The support wheel 323 will generate friction with the side of the plate, causing the plate to move to the left and adjust the center of gravity of the plate so that it gradually approaches the center of the frame 1. During the adjustment process, the position change of the plate should be continuously observed, and the rotation time and speed of the second motor 42 should be controlled according to the actual situation.

[0052] After the plate is adjusted to a relatively centered position, continue to slowly lift the hoisting device to move the plate to the designated position. During the movement, the condition of the plate should be closely monitored. If necessary, the drive assembly 4 can be restarted for adjustment. When the hoisting device is moved above the designated position, the overhead electric hoist is slowly lowered according to the method in Example 1 to accurately place the plate in the target position. After the plate is placed, the clamping release operation in Example 1 is performed. Then, the power of the second motor 42 in the drive assembly 4 is turned off, the hoisting device is lifted to a suitable height, and moved to the storage position.

[0053] The method of use in this embodiment, by flexibly activating the drive component 4 during the hoisting process, can adjust the position of the plate in a timely manner, ensuring that the center of gravity of the plate is relatively centered. This effectively solves the safety hazards and operational difficulties caused by the positional deviation of the plate during hoisting, and further improves the reliability and efficiency of hoisting operations.
