Description

Technical Field

[0001] This utility model relates to the technical field of a multi-functional magnetic lifting tool for wind turbine hoisting, and more particularly to a multi-functional magnetic lifting tool for wind turbine hoisting. Background Technology

[0002] Permanent magnet lifters: also known as permanent magnet chucks, magnetic lifters, magnetic hoists, lifting magnets, lifting permanent magnets, permanent magnets, etc. They are characterized by small size, stronger holding force, no electricity required, almost zero residual magnetism, and high safety factor. Permanent magnet lifters are often used for lifting wind turbines.

[0003] The inventors discovered during daily use of permanent magnet lifters that the bottom of a typical permanent magnet lifter is flat. Consequently, when lifting round materials, the contact area between the permanent magnet lifter and the round material is small, making it inconvenient to lift round materials and causing problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-functional magnetic lifting tool specifically for wind turbine hoisting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional magnetic lifting device for wind turbine hoisting, comprising a permanent magnet jack, a connecting device at the bottom of the permanent magnet jack, a binding device at the bottom of the permanent magnet jack, the connecting device comprising a circular groove formed at the bottom of the permanent magnet jack, a limiting rod inserted inside the circular groove, a retaining ring fixedly connected to the surface of the limiting rod, and a connecting seat fixedly connected to the bottom of the limiting rod, the bottom of the connecting seat being an arc-shaped surface.

[0006] The aforementioned components achieve the following effects: Under the action of the limiting rod and the retaining ring, the connecting seat can be initially locked onto the bottom of the permanent magnet lifter, thus achieving the limiting function. Since the bottom of the connecting seat is curved, it is convenient to fix round objects. Since the material of the connecting seat is the same as that of the permanent magnet lifter, the connecting seat can also generate magnetic force. When it is necessary to lift the fan, the fan is placed on the ground, and the permanent magnet lifter magnetically holds the object. Under the action of the connecting device, round objects can be magnetically attracted, and under the action of the binding device, the object will not fall off, thus achieving the multi-functional function of the permanent magnet lifter.

[0007] Preferably, a pad is fixedly connected to the top of the connecting seat, and the pad is a rubber pad.

[0008] The effect achieved by the above components is that, under the action of the pad, the connecting seat will not directly contact the permanent magnet lifter, thus avoiding the phenomenon of rigid contact.

[0009] Preferably, a rectangular block is fixedly connected to the side of the permanent magnet lifter, a rectangular plate is rotatably connected to the side of the rectangular block, and a bolt is threadedly connected to the side of the rectangular plate, with the bolt inserted into the interior of the connecting seat.

[0010] The effect achieved by the above components is that, under the action of the bolts, the connecting seat can be fixed to the bottom of the permanent magnet lifter, thus facilitating the handling of magnetic round objects.

[0011] Preferably, a conical block is fixedly connected to one end of the bolt.

[0012] The effect achieved by the above components is that, under the action of the conical block, the bolt can be inserted into the interior of the connector more smoothly.

[0013] Preferably, the rectangular block has a screw threadedly connected to its side, and the screw is inserted into the interior of the rectangular plate.

[0014] The aforementioned components achieve the following effects: the screws fix the position of the rectangular plate, preventing it from failing to limit the position of the connecting seat. When connecting the connecting seat, place it on the ground, insert the limiting rod into the circular groove, and the retaining ring locks the limiting rod inside the groove. After rotating the rectangular plate to fit against the connecting seat, screw the screws into the rectangular plate to fix it, preventing displacement. The bolts are then quickly screwed into the connecting seat through the conical block for fixation, thus achieving the function of fixing the connecting seat. Since the material of the connecting seat is the same as that of the permanent magnet lifter, the connecting seat can also generate magnetic force, thus achieving the function of removing garbage and facilitating the magnetic attraction of round items.

[0015] Preferably, the binding device includes a strap disposed at the bottom of the connector, the strap being a nylon rope.

[0016] The effect achieved by the above components is that, under the action of the straps, the items magnetically attached to the bottom of the connector can be secured, preventing the items from falling off.

[0017] Preferably, a ring is fixedly connected to the side of the connecting seat, and a hook is engaged inside the ring, with one end of the strap fixedly connected to one end of the hook.

[0018] The effect achieved by the above components is that, with the help of the hook, the strap can be quickly removed from the inside of the ring, thus facilitating the binding of items.

[0019] Preferably, the surface of the strap has a through groove, a screw is inserted into the through groove, and a nut is threaded onto the surface of the screw.

[0020] The aforementioned components achieve the following effects: Under the action of the screw and nut, the position of the strap can be adjusted, thus achieving the desired adjustment. When the item is magnetically attached to the bottom of the connector, the hook is hung inside the ring, the strap is wrapped around the magnetic item once, and the hook at the other end of the strap is hung inside the ring. When the strap is long, the screw is passed through the slot, causing the strap to be folded and strung together, thereby adjusting the length of the strap. Once the appropriate length is reached, the nut is screwed onto the surface of the screw to fix it, thus achieving the purpose of binding the item.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a connecting device, when a connecting seat needs to be connected, the connecting seat is placed on the ground, and the limiting rod is inserted into the inside of the circular groove. Under the action of the retaining ring, the limiting rod is locked inside the circular groove. After the rectangular plate is rotated to fit against the connecting seat, the screw is screwed into the inside of the rectangular plate to fix the rectangular plate, thus preventing the rectangular plate from shifting. The bolt is quickly screwed into the inside of the connecting seat through the conical block to fix it, thereby achieving the function of fixing the connecting seat. Since the material of the connecting seat is the same as that of the permanent magnet lifter, the connecting seat can also generate magnetic force, thus achieving the function of removing garbage and also facilitating the magnetic attraction of round items. This solves the problem that the bottom of permanent magnet cranes is mostly flat, making it inconvenient to lift round materials. Attached Figure Description

When hoisting a wind turbine, the load is placed on the ground, and the permanent magnet lifter 1 magnetically holds the load. Under the action of the connecting device 2, round loads can be magnetically attracted, and under the action of the binding device 3, the load will not fall off. Thus, the permanent magnet lifter 1 achieves its multi-functional function. (The working principle of the magnetic lifting device mainly relies on the magnetic properties of neodymium iron boron permanent magnet material. Neodymium iron boron permanent magnet material has high magnetic energy product and coercivity, and can maintain strong magnetism after being magnetized and is not easy to demagnetize. The magnetic lifting device utilizes this high-performance permanent magnet material and achieves hoisting and unloading functions through a unique magnetic circuit design.)

A retaining ring is fixedly connected to the surface of the limiting rod 27, and a connecting seat 25 is fixedly connected to the bottom of the limiting rod 27. The bottom of the connecting seat 25 is arc-shaped. Under the action of the limiting rod 27 and the retaining ring, the connecting seat 25 can be initially locked at the bottom of the permanent magnet lifter 1, thus achieving the limiting function. Since the bottom of the connecting seat 25 is arc-shaped, it is convenient to fix round objects. Since the material of the connecting seat 25 is the same as that of the permanent magnet lifter 1, the connecting seat 25 can also generate magnetic force. When it is necessary to lift the fan, the object of the fan can be... The item is placed on the ground and magnetically held in place by the permanent magnet lifter 1. Under the action of the connecting device 2, round items can be magnetically attracted. The binding device 3 prevents the item from falling off, thus achieving the multi-functionality of the permanent magnet lifter 1. A rubber pad 26 is fixedly connected to the top of the connecting seat 25, preventing direct contact between the connecting seat 25 and the permanent magnet lifter 1, avoiding rigid contact. A rectangular block 21 is fixedly connected to the side of the permanent magnet lifter 1, and a rectangular plate 22 is rotatably connected to the side of the rectangular block 21. Bolts 24 are threadedly connected to the side of the rectangular plate 22. Bolt 24 is inserted into the interior of connector 25. Under the action of bolt 24, connector 25 can be fixed to the bottom of permanent magnet lifter 1, thus facilitating the insertion of magnetic round objects. One end of bolt 24 is fixedly connected to a conical block 28. Under the action of conical block 28, bolt 24 can be inserted more smoothly into the interior of connector 25. A screw 23 is threaded onto the side of rectangular block 21. Screw 23 is inserted into the interior of rectangular plate 22. Under the action of screw 23, the position of rectangular plate 22 can be fixed, thus avoiding the phenomenon that rectangular plate 22 cannot limit the position of connector 25. When connector 25 needs to be connected, connector 24 is... 5. Place it on the ground and insert the limiting rod 27 into the inside of the circular groove 29. Under the action of the retaining ring, the limiting rod 27 is locked inside the circular groove 29. Rotate the rectangular plate 22 until it fits against the connecting seat 25, and screw the screw 23 into the inside of the rectangular plate 22 to fix the rectangular plate 22 and prevent the rectangular plate 22 from shifting. Quickly screw the bolt 24 into the inside of the connecting seat 25 through the conical block 28 to fix it, thereby achieving the function of fixing the connecting seat 25. Since the material of the connecting seat 25 is the same as the material of the permanent magnet lifter 1, the connecting seat 25 can also generate magnetic force, thereby achieving the function of garbage collection and also facilitating the magnetic attraction of round items.

[0030] Reference Figure 4The binding device 3 includes a binding strap 32, made of nylon rope, located at the bottom of the connecting seat 25. The binding strap 32 secures items magnetically attached to the bottom of the connecting seat 25, preventing them from falling off. A ring 31 is fixedly connected to the side of the connecting seat 25. A hook 33 is fitted inside the ring 31. One end of the binding strap 32 is fixedly connected to one end of the hook 33. The hook 33 allows the binding strap 32 to be quickly removed from the ring 31, facilitating the binding of items. A through groove 36 is formed on the surface of the binding strap 32, and a screw 34 is inserted into the through groove 36. The surface of the screw 34 is screwed... The threaded connection is secured with a nut 35. Under the action of the screw 34 and the nut 35, the position of the strap 32 can be adjusted, thus achieving the function of adjustment. When the item is magnetically attached to the bottom of the connecting seat 25, the hook 33 is hung inside the ring 31, the strap 32 is wrapped around the magnetic item once, and the hook 33 at the other end of the strap 32 is hung inside the ring 31. When the strap 32 is long, the screw 34 is passed through the through groove 36, so that the strap 32 is folded and strung together, thereby adjusting the length of the strap 32. When the appropriate length is reached, the nut 35 is screwed onto the surface of the screw 34 to fix it, thus achieving the function of binding the item.

[0031] Working principle: When using a multi-functional magnetic lifting tool specifically for wind turbine installation, the wind turbine is placed on the ground. The permanent magnet lifter 1 magnetically holds the item in place. Under the action of the connecting device 2, round items can be magnetically attracted. The binding device 3 prevents the item from falling off, thus achieving the multi-functional function of the permanent magnet lifter 1. (The working principle of the magnetic lifting tool mainly relies on the magnetic properties of neodymium iron boron permanent magnet material. Neodymium iron boron permanent magnet material has high magnetic energy product and coercivity, and can maintain strong magnetism after being magnetized, making it difficult to demagnetize. The magnetic lifting tool utilizes this high-performance permanent magnet material and achieves lifting and unloading functions through a unique magnetic circuit design.) When connecting the connecting seat 25, the connecting seat 25 is placed on the ground, and the limiting rod 27 is inserted into the circular groove 29. Under the action of the retaining ring, the limiting rod 27 is locked inside the circular groove 29. The rectangular plate 22 is then rotated... After the connecting seat 25 is attached, screw 23 is screwed into the inside of the rectangular plate 22 to fix the rectangular plate 22 and prevent the rectangular plate 22 from shifting. Bolt 24 is quickly screwed into the inside of the connecting seat 25 through the conical block 28 to fix it, thereby achieving the function of fixing the connecting seat 25. Since the material of the connecting seat 25 is the same as that of the permanent magnet lifter 1, the connecting seat 25 can also generate magnetic force, thereby achieving the function of garbage collection and also facilitating the magnetic attraction of round items. When the item is magnetically attached to the bottom of the connecting seat 25, hook 33 is hung inside the ring 31, and strap 32 is wrapped around the magnetic item. The other end of the strap 32 is hung inside the ring 31. When the strap 32 is long, screw 34 is passed through the through groove 36, so that the strap 32 is folded and strung together, thereby adjusting the length of the strap 32. When the appropriate length is adjusted, nut 35 is screwed onto the surface of screw 34 to fix it, thereby achieving the function of binding the item.
