Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a tile-shaped magnetic permanent magnet lifting device that is easy to fix. Background Technology

[0002] In industrial production, the handling of curved or cylindrical magnetically conductive workpieces such as pipes and rollers has always been a challenge. Traditional permanent magnet lifters are mostly flat designs, with a small contact area with curved workpieces, resulting in weak adhesion and easy slippage. This not only leads to low efficiency but also poses safety hazards. To solve this problem, tile-shaped permanent magnet lifters adapted to curved surfaces have emerged and are widely used in fields such as machinery manufacturing and pipeline engineering. They have become an important piece of equipment to replace traditional lifting methods and improve operational safety and efficiency. However, when using a lifter, a fixing device is required.

[0003] This type of fixed tile-shaped magnetic permanent magnet lifter has a basic structure of an integral rigid arm. One end is connected to the main body of the lifting equipment through a fixed base, and the other end is equipped with a hook and locking device. The arm is made of high-strength material. The fixed base ensures the stability of the arm position. After the hook is attached to the lifter, the locking device prevents it from falling off. The rigidity of the arm is used to support the load, and the tile-shaped magnetic permanent magnet lifter is used to lift and move heavy objects.

[0004] However, the hook of this type of equipment may be opened due to external impact, leading to the danger of the crane falling off. Secondly, the center of gravity of most suspended objects (such as irregularly shaped workpieces or non-homogeneous components) is not the geometric center. If the position of the lifting point is fixed, the resultant force line of the lifting point will deviate from the center of gravity. To solve the above problems, a tile-shaped magnetic permanent magnet crane device that is easy to fix is ​​proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tile-shaped permanent magnet lifting device that is easy to fix, aiming to improve the problems in the prior art where the hook locking device is easily opened by external impact, posing a risk of the lifting device falling off, and the fixed lifting point is difficult to match the non-geometric center of gravity of irregular or non-homogeneous objects, resulting in the deviation of the resultant force line of the lifting point.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tile-shaped permanent magnet magnetic lifter device that is easy to fix, comprising a base, a suspension arm fixedly installed on the upper side of the base, a winch fixedly installed on the suspension arm, a steel rope inside the winch, a mounting base fixedly connected to the lower side of the steel rope, a hook fixedly installed inside the mounting base, a limiting arc plate provided on the hook, a second fixing block fixedly installed on the right side of the hook, a groove provided inside the second fixing block, a first fixing block fixedly installed on the right side of the limiting arc plate, a pull rod inside the first fixing block, a limiting block fixedly connected to the lower side of the pull rod, a spring provided on the outer side of the pull rod, the spring being disposed between the inner wall of the first fixing block and the limiting block, a lifting ring inside the hook, a position adjustment component fixedly installed on the lower side of the lifting ring, and a magnetic lifter fixedly installed on the lower side of the position adjustment component.

[0007] Furthermore, the position adjustment component includes a slide rail, which is fixedly mounted on the magnetic lifter. A slider is provided on the outer side of the slide rail, and limit plates are provided at both ends of the slide rail. Positioning holes are provided inside both the slider and the slide rail. A positioning rod is provided inside the slider, and a wing nut is threaded onto the outer side of the positioning rod.

[0008] Furthermore, a guide wheel is fixedly installed on the reinforcing rope, and the reinforcing rope is set on the guide wheel.

[0009] Furthermore, the limiting block is slidably connected inside the groove.

[0010] Furthermore, the slider is slidably connected to the outside of the slide rail, and the positioning rod is slidably connected to the inside of the positioning hole.

[0011] Furthermore, the limiting arc plate is rotatably connected to the hook.

[0012] Furthermore, a handle is provided on the right side of the magnetic lifter.

[0013] Furthermore, a controller is fixedly installed on the left side of the suspension arm, and the controller is electrically connected to the winch.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the pull rod, spring, and limiting block of the hook cooperate with the fixing block and groove of the hook. The pull rod drives the limiting block to slide into the groove, and the spring generates elastic force to lock. When impacted, the spring force increases, enhancing the locking force and preventing the lifting device from falling off.

[0016] 2. In this utility model, the slider slides along the slide rail, the positioning hole, the positioning rod and the wing nut of the position adjustment component, and the positioning rod passes through the positioning hole and is fixed by screwing on the wing nut, so as to realize the adjustment of the lifting point position and adapt to the center of gravity shift.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a tile-shaped permanent magnet lifting device that is easy to fix, including a base 1. A suspension arm 2 is fixedly installed on the upper side of the base 1. A winch 3 is fixedly installed on the suspension arm 2. A steel cable 4 is provided inside the winch 3. A mounting base 6 is fixedly connected to the lower side of the steel cable 4. A hook 8 is fixedly installed inside the mounting base 6. A limiting arc plate 7 is provided on the hook 8. A second fixing block 14 is fixedly installed on the right side of the hook 8. A groove 13 is opened inside the fixing block 14. A first fixing block 9 is fixedly installed on the right side of the limiting arc plate 7. The limiting arc plate 7 is rotatably connected to the hook 8. A pull rod 1 is provided inside the first fixing block 9. 0. A limit block 12 is fixedly connected to the lower side of the pull rod 10. The limit block 12 is slidably connected inside the groove 13. A spring 11 is provided on the outer side of the pull rod 10. The spring 11 is located between the inner wall of the fixed block 9 and the limit block 12. A lifting ring 15 is provided inside the hook 8. A position adjustment component 18 is fixedly installed on the lower side of the lifting ring 15. A magnetic lifter 19 is fixedly installed on the lower side of the position adjustment component 18. A handle 16 is provided on the right side of the magnetic lifter 19. A guide wheel 5 is fixedly installed on the steel rope 4. The steel rope 4 is located on the guide wheel 5. A controller 17 is fixedly installed on the left side of the suspension arm 2. The controller 17 is electrically connected to the winch 3.

[0025] Specifically, the operator pulls up the lever 10, disengaging the limiting block 12 from the groove 13 of the fixing block 14. Then, the limiting arc plate 7 is separated from the hook 8 via the rotating shaft, opening the hook 8. The lifting ring 15 of the magnetic lifter 19 is connected to the hook 8. The lever 10 is lowered, and the limiting block 12 is joined to the fixing block 14. The spring 11 resets, causing the limiting block 12 to engage in the groove 13. The torsion spring inside the rotating shaft assists in resetting the limiting arc plate 7 and the hook 8, achieving automatic reset when the hook 8 is closed. After the magnetic lifter 19 is secured, it is activated via the control handle 16. The magnetic lifter 19 attracts the workpiece, and then the controller 17 on the left side of the suspension arm 2 is turned on to start the winch 3, control the length of the steel rope 4, and complete the transfer and lifting work with the magnetic lifter 19 with the help of the guide wheel 5. During this process, the pull rod 10, spring 11, and limit block 12 of the limit arc plate 7 cooperate with the fixing block 14 and groove 13 of the hook 8. The pull rod 10 drives the limit block 12 to slide into the groove 13, and the spring 11 generates elastic force to lock. When impacted, the elastic force of the spring 11 increases, enhancing the locking force and preventing the lifter from falling off.

[0026] Reference Figure 1 and Figure 2The position adjustment component 18 includes a slide rail 182, which is fixedly mounted on the magnetic lifter 19. A slider 181 is provided on the outer side of the slide rail 182. Limit plates 186 are provided at both ends of the slide rail 182. Positioning holes 183 are provided inside both the slider 181 and the slide rail 182. A positioning rod 184 is provided inside the slider 181. A wing nut 185 is threaded to the outer side of the positioning rod 184. The slider 181 is slidably connected to the outer side of the slide rail 182, and the positioning rod 184 is slidably connected to the inside of the positioning hole 183.

[0027] Specifically, when encountering irregularly shaped or unevenly distributed workpieces, the slider 181 on the sliding rail 182 is adjusted to a different position, and the limiting plate 186 restricts the sliding range of the slider 181. After determining the position, the positioning rod 184 is placed into the positioning hole 183 at the corresponding position of the slider 181 and the rail 182. The positioning rod 184 is then threaded and fixed with the wing nut 185. This process can flexibly adapt to different object centers of gravity, making the resultant force line of the lifting point coincide with the center of gravity, avoiding tilting and swaying caused by the offset of the center of gravity, and improving the lifting stability.

[0028] Working principle: When using this equipment, the operator first pulls up the lever 10, removes the limiting block 12 from the groove 13 of the fixing block 2 14, separates the limiting arc plate 7 from the hook 8, opens the hook 8, connects the lifting ring 15 of the magnetic lifter 19 to the hook 8, then lowers the lever 10, completely splices the limiting block 12 with the fixing block 2 14, and fixes the magnetic lifter 19. Then, the operator first controls the handle 16 to start the magnetic lifter 19, which attracts the workpiece. Then, the operator opens the controller 17 on the right side of the suspension arm 2, and the winch 3 starts. The winch 3 controls the length of the steel rope 4. With the cooperation of the guide wheel 5, the transfer and lifting work of the magnetic lifter 19 is completed.

[0029] When encountering irregularly shaped or unevenly distributed workpieces, first adjust the position of the slider 181 on the slide rail 182. After determining the position, use the positioning rod 184 to insert into the two positioning holes 183 at the corresponding positions, and then use the wing nut 185 to fix the positioning rod 184 in the positioning hole 183 so that the resultant force line of the lifting point coincides with the center of gravity.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
