Technical Field
[0001] The utility model relates to the technical field of overhead crane lifting, in particular to a new type of magnetic disk for improving the steel lifting of a finished bar overhead crane. Background Art
[0002] With the increasing production cost, the output has to be increased. To increase the output, the production rhythm must be accelerated. The existing specifications of electromagnets can no longer meet the requirements of the fast production rhythm. Affected by the speed increase, the speed of the finished product offline is accelerated. To meet the on-site requirements, while the overhead crane driver pays attention to the lifting speed, the accuracy and precision of the lifting operation are affected to a certain extent. Especially when lifting bars, due to the small contact area between the bar and the electromagnet and insufficient adsorption force, after the lifting speed is accelerated, it is easy to shake, resulting in accidents such as steel dropping and abrasion. The mismatch between the overhead crane lifting capacity and the speed increase of the rolling line and the cooling bed has become a bottleneck restricting the improvement of production efficiency. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a new type of magnetic disk for improving the steel lifting of a finished bar overhead crane in view of the above deficiencies of the prior art, which can improve the adsorption capacity, avoid the occurrence of safety accidents, can increase the lifting speed, improve the production efficiency, and has the characteristics of convenient use and strong practicability.
[0004] The technical solution adopted by the utility model is: a new type of magnetic disk for improving the steel lifting of a finished bar overhead crane, including a magnetic disk body. A plurality of arc-shaped grooves adapted to bar-shaped steel are opened below the magnetic disk body. A plurality of connecting seats distributed in a rectangular shape are arranged on the top of the magnetic disk body. Lifting lugs are arranged on the connecting seats. A magnetic enhancement device for increasing the magnetic force is arranged at the middle position of the top of the magnetic disk body. A detachable anti-falling component is arranged at the bottom of the magnetic disk body. A junction box is arranged on the top of the magnetic disk body.
[0005] As a further improvement, the magnetic enhancement device includes an electromagnet and a circular mounting sleeve. The circular mounting sleeve is arranged on the magnetic disk body, and the electromagnet is installed in the circular mounting sleeve.
[0006] Further, the anti-falling component includes a hanging net and a plurality of hanging ears. The plurality of hanging ears are respectively arranged on both sides of the magnetic disk body. Hooks are arranged on the hanging ears, and the four corners of the hanging net are detachably hung on the hooks through hanging rings.
[0007] Further, a guide plate is arranged between two adjacent arc-shaped grooves, and the cross-section of the guide plate is in an inverted triangular shape.
[0008] Further, a locking bolt is threadedly connected to the circular mounting sleeve, and the locking bolt passes through the circular mounting sleeve and presses against the electromagnet.
[0009] Further, the number of the arc-shaped grooves is four, and the four arc-shaped grooves are evenly arranged on the disk body.
[0010] Advantageous Effects
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] A novel disk for a finished bar overhead crane of the utility model to improve the lifting of steel bars. When lifting bar-shaped steel bars, under the action of the guiding plate, each bar-shaped steel bar respectively enters the arc-shaped groove, and the upper arc surface of the bar-shaped steel bar just fits the arc-shaped groove, thereby effectively increasing the contact surface between the disk body and the bar-shaped steel bar, making the adsorption force of the disk body on the bar-shaped steel bar greater during the lifting process, and playing a fixing role, effectively preventing the bar-shaped steel bar from shaking during the lifting process, thereby effectively preventing the bar-shaped steel bar from falling and avoiding the occurrence of safety accidents. At the same time, after increasing the adsorption force, the lifting speed can be increased, effectively improving the production efficiency. By setting a magnetic enhancement device, when it is necessary to lift materials with a larger weight, the use of the electromagnet can be started, and under the clamping of the electromagnet, the magnetic adsorption force is effectively increased to meet the lifting requirements of different weights. When handling a small number of bar-shaped steel bars with a large weight, by setting an anti-falling component, when the bar-shaped steel bar is lifted to a certain height, the on-site personnel hang a hanging net below, effectively preventing the bar-shaped steel bar from falling from a height when it is lifted to a high place, thereby preventing the occurrence of safety accidents and playing a protective role. This disk can efficiently lift bar-shaped steel bars, has a high lifting efficiency, and also has high safety, and has the characteristics of strong practicability and wide application range.

Specific Embodiments
[0016] The following further describes the utility model with reference to the specific embodiments in the drawings.
[0017] Refer to Figure 1-2As shown in the figure, a new type of magnetic disk for a bar finished product overhead crane of the present utility model to improve the lifting of steel includes a magnetic disk body 1. A plurality of arc-shaped grooves 4 adapted to bar-shaped steel 5 are opened below the magnetic disk body 1. A plurality of connection seats 6 distributed in a rectangular shape are provided on the top of the magnetic disk body 1. A lifting lug 7 is provided on the connection seat 6. A magnetic enhancement device 2 for increasing magnetic force is provided at the middle position on the top of the magnetic disk body 1. A detachable anti-falling component 3 is provided at the bottom of the magnetic disk body 1. A junction box 1 is provided on the top of the magnetic disk body 1. When lifting bar-shaped steel 5, under the action of the guiding plate 5, each bar-shaped steel 5 respectively enters into the arc-shaped groove 4. The upper arc surface of the bar-shaped steel 5 just fits with the arc-shaped groove 4, thereby effectively increasing the contact surface between the magnetic disk body 1 and the bar-shaped steel 5, making the adsorption force of the magnetic disk body 1 on the bar-shaped steel 5 greater during the lifting process, and playing a fixing role, effectively preventing the bar-shaped steel 5 from shaking during the lifting process, thereby effectively preventing the bar-shaped steel 5 from falling and avoiding the occurrence of safety accidents. At the same time, after increasing the adsorption force, the lifting speed can be accelerated, effectively improving the production efficiency. By setting the magnetic enhancement device 2, when it is necessary to lift materials with a larger weight, the use of the electromagnet 21 can be started. Under the clamping of the electromagnet 21, the magnetic adsorption force is effectively increased to meet the lifting requirements of different weights. By setting the anti-falling component 3, when the bar-shaped steel is lifted to a certain height, the on-site personnel hang a hanging net 33 below, effectively preventing the bar-shaped steel 5 from falling from a height when it is lifted to a high place, thereby preventing the occurrence of safety accidents and playing a protective role. This magnetic disk can efficiently lift bar-shaped steel 5, with high lifting efficiency and high safety.
[0018] Specifically, the magnetic enhancement device 2 includes an electromagnet 21 and a circular mounting sleeve 22. The circular mounting sleeve 22 is arranged on the magnetic disk body 1. The electromagnet 21 is installed in the circular mounting sleeve 22. The circular mounting sleeve 22 effectively limits the position of the electromagnet 21, enabling it to be installed on the magnetic disk body 1. When it is necessary to lift materials with a larger weight, the use of the electromagnet 21 can be started. Under the clamping of the electromagnet 21, the magnetic adsorption force is effectively increased.
[0019] Furthermore, the anti-falling component 3 includes a hanging net 33 and a plurality of hanging ears 31. The plurality of hanging ears 31 are respectively arranged on both sides of the magnetic disk body 1. A hook 32 is provided on the hanging ear 31. The four corners of the hanging net 33 are detachably hung on the hook 32 through suspension rings. The hanging net 33 can be quickly hung on the hanging ear 31 through the suspension rings, effectively unfolding below the magnetic disk body 1 and playing a role in preventing the heavy bar-shaped steel 5 from falling. By setting it as a detachable structure, when lifting a large number of bar-shaped steel 5 with a small weight, there is no need to hang the hanging net, thereby accelerating the lifting speed.
[0020] Furthermore, a guiding plate 8 is provided between two adjacent arc-shaped grooves 4. The cross-section of the guiding plate 8 is in an inverted triangular shape. Under the action of the guiding plate 8, the bar-shaped steel 5 can be separated and adsorbed orderly.
[0021] Further, a locking bolt 9 is threadedly connected to the circular mounting sleeve 22. After passing through the circular mounting sleeve 22, the locking bolt 9 presses against the electromagnet 21, enabling quick locking and fixing of the electromagnet 21.
[0022] Further, the number of arc-shaped grooves 4 is four, and the four arc-shaped grooves 4 are evenly arranged on the disk body 1, enabling the disk body 1 to lift four bar-shaped steel materials 5 at a time, improving the lifting efficiency and saving lifting time.
[0023] When the novel disk for a finished bar material overhead crane in this embodiment is in use for lifting steel materials, under the action of the guide plate 5, each bar-shaped steel material 5 enters the arc-shaped groove 4 respectively, and the upper arc surface of the bar-shaped steel material 5 just fits the arc-shaped groove 4, effectively increasing the contact surface between the disk body 1 and the bar-shaped steel material 5. This makes the adsorption force of the disk body 1 on the bar-shaped steel material 5 greater during the lifting process and plays a fixing role, effectively preventing the bar-shaped steel material 5 from shaking during the lifting process, thus effectively preventing the bar-shaped steel material 5 from falling and avoiding the occurrence of safety accidents. At the same time, after increasing the adsorption force, the lifting speed can be increased, effectively improving the production efficiency. By setting the magnetic enhancement device 2, when it is necessary to lift materials with a larger weight, the electromagnet 21 can be activated. Under the clamping of the electromagnet 21, the magnetic adsorption force is effectively increased to meet the lifting requirements of different weights. By setting the anti-falling component 3, when the bar-shaped steel material is lifted to a certain height, on-site personnel hang a hanging net 33 below, effectively preventing the bar-shaped steel material 5 from falling from a high altitude when lifted to a high place, thus preventing the occurrence of safety accidents and playing a protective role. The novel disk for a finished bar material overhead crane of the present utility model improves the adsorption capacity, avoids the occurrence of safety accidents, can increase the lifting speed, and enhances the production efficiency, and has the characteristics of convenient use and strong practicability.
[0024] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can be made, which will not affect the implementation effect of the present utility model and the practicability of the patent.
