Disk drive for rapid hoisting of large angle steel for iron towers

Abstract

This utility model belongs to the technical field of angle steel production lines, and particularly to a magnetic chuck device for rapid hoisting of large angle steel for iron towers, including an electromagnetic chuck body. When the crane descends for hoisting, the bottom of the electromagnetic chuck body first contacts the apex of the angle steel, forming the first magnetic attraction surface. The strong magnetic force generated by the electromagnetic chuck body tightly attracts the apex of the angle steel. Simultaneously, the movable suction rod, under the action of magnetic force, contacts the two side supports of the angle steel, forming the second and third magnetic attraction surfaces. Thus, through the combined action of the bottom of the electromagnetic chuck body and the movable suction rod, multi-point stable attraction of the angle steel is achieved, greatly increasing the attraction area and attraction force, effectively improving the safety and stability of the hoisting process. During hoisting, rubber shock-absorbing pads provide cushioning and shock absorption, protecting the bottom of the electromagnetic chuck body. The removable rubber shock-absorbing pads are easy to replace.

Description

Technical Field

[0001] This utility model relates to the technical field of angle steel production lines, specifically to a disk device for rapid hoisting of large angle steel for iron towers. Background Technology

[0002] In the power sector, transmission towers serve as crucial infrastructure supporting high-voltage transmission lines, making their structural stability and safety paramount. Large angle steel is one of the core materials used in tower construction. Its unique L-shaped structure provides strong support and stability, effectively resisting various external forces in the natural environment, such as strong winds and earthquakes. These angle steels typically have side lengths of 150-300mm or more. This larger size allows them to perform exceptionally well in bearing weight and coping with complex stresses, meeting the stringent requirements of power transmission towers in long-distance, large-span projects.

[0003] In the production process of large angle steel for iron towers, the transfer and stacking of angle steel are essential steps. These operations require frequent movement of angle steel from one workstation to another and stacking it according to certain rules for subsequent processing, transportation, and installation. Currently, some electromagnetic chucks have flat contact surfaces, which only contact the top corner of the angle steel during hoisting. The small contact area of ​​the chuck results in weak suction, making safe hoisting impossible. Therefore, we have proposed a magnetic disk device for rapid hoisting of large angle steel for iron towers to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a disk device for rapid hoisting of large angle steel for iron towers, which has the following advantages:

[0016] This invention, when the crane is lowered for lifting operations, first brings the bottom of the electromagnetic chuck into contact with the apex of the angle steel, forming the first magnetic attraction surface. The powerful magnetic force generated by the electromagnetic chuck tightly attracts the angle steel. Simultaneously, the movable suction rod, under the influence of the magnetic force, contacts the two side supports of the angle steel, forming the second and third magnetic attraction surfaces. Thus, through the combined action of the bottom of the electromagnetic chuck and the movable suction rod, multi-point stable attraction of the angle steel is achieved, greatly increasing the attraction area and force, effectively improving the safety and stability of the lifting process. During lifting, the rubber shock-absorbing pads provide cushioning and shock absorption, preventing direct collision between the bottom of the electromagnetic chuck and the angle steel, protecting the bottom of the electromagnetic chuck. The removable rubber shock-absorbing pads also facilitate replacement. Attached Figure Description

[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] Example

[0025] like Figure 1-5As shown, an embodiment of this utility model proposes a disk device for rapid hoisting of large angle steel for iron towers, including an electromagnetic chuck body 1. Two lifting lugs 2 are welded to the top of the electromagnetic chuck body 1. A U-shaped hole 3 is opened on the electromagnetic chuck body 1. Multiple reinforcing plates 4 are welded between the inner walls on both sides of the U-shaped hole 3. External hooks 5 are welded to both sides of the electromagnetic chuck body 1. Multiple movable suction rods 6 are movably contacted on the external hooks 5. Rubber shock-absorbing pads 7 are movably contacted at the bottom of the electromagnetic chuck body 1. Four insertion holes 8 are opened on the bottom inner wall of the U-shaped hole 3. A U-shaped plate 9 is welded to the bottom inner wall of the U-shaped hole 3. A motor 10 is fixedly connected to one side of the U-shaped plate 9. A lead screw 11 is rotatably connected to the inner walls on both sides of the U-shaped plate 9. A movable plate 12 is threadedly connected to the lead screw 11. Two locking pins 13 are welded to one side of the movable plate 12. Four mounting rods 14 are fixedly connected to the top of the rubber shock-absorbing pads 7. A slot 15 is opened on one side of the mounting rod 14. The slot 15 is engaged with the corresponding locking pin 13.

[0026] In use, before lifting angle steel, connect the crane hook to the two lifting lugs 2 on the top of the electromagnetic chuck body 1. Then, turn on the power to supply power to the electromagnetic chuck body 1, enabling it to have magnetic adsorption capabilities. At the same time, since the external hook 5 is connected to the electromagnetic chuck body 1, according to the principle of magnetic conduction, the external hook 5 will also be magnetized and generate magnetic force. The magnetic force generated by the external hook 5 will be further conducted to the movable suction rod 6, making the movable suction rod 6 also magnetic. When the crane lowers to perform the lifting operation, the bottom of the electromagnetic chuck body 1 first contacts the top corner of the angle steel. At this time, the bottom of the electromagnetic chuck body 1 and the top corner of the angle steel form the first magnetic attraction surface. The electromagnetic chuck body 1 generates a strong magnetic force that tightly attracts the top corner of the angle steel. At the same time, the movable suction rod 6 makes contact with the two side supports of the angle steel under the action of magnetic force, forming a second and third magnetic attraction surface. In this way, through the combined action of the bottom of the electromagnetic chuck body 1 and the movable suction rod 6, multi-point stable attraction of the angle steel is achieved, which greatly increases the attraction area and attraction force, effectively improving the safety and stability of the hoisting process. During the hoisting process, the rubber shock-absorbing pad 7 can play a role in buffering and shock absorption, preventing the bottom of the electromagnetic chuck body 1 from directly colliding with the angle steel and protecting the bottom of the electromagnetic chuck body 1. At the same time, the detachable rubber shock-absorbing pad 7 is easy to replace.

[0027] In some embodiments, the ends of two lead screws 11 that are close to each other are fixedly connected, the threads of the two lead screws 11 are in opposite directions, and the end of one of the lead screws 11 extends out of the U-shaped plate 9 and is fixedly connected to the output shaft of the motor 10.

[0028] When the rubber shock absorber pad 7 needs to be replaced after a long period of use, the motor 10 is started by switching the switch 17 to rotate in the forward direction. The motor 10 drives the lead screw 11 to rotate, and the lead screw 11 drives the moving plate 12 to move. Under the action of the opposite screw direction, the two moving plates 12 move towards each other. The moving plate 12 drives the locking pin 13 to separate from the corresponding locking groove 15. Then, the rubber shock absorber pad 7 is removed. Then, the mounting rod 14 on the other rubber shock absorber pad 7 is inserted into the loop hole 3 through the insertion hole 8. Then, the motor 10 is started to rotate in the reverse direction. The motor 10 drives the moving plate 12 to move through the lead screw 11. The moving plate 12 drives the locking pin 13 to engage with the corresponding locking groove 15, which facilitates the replacement of the rubber shock absorber pad 7.

[0029] In some embodiments, two square rods 16 are welded between the inner walls of the two sides of the U-shaped plate 9, and the square rods 16 are slidably connected to the movable plate 12.

[0030] The square rod 16 serves as a limit, preventing the movable plate 12 from shifting during movement.

[0031] In some embodiments, a switch 17 is provided on the bottom inner wall of the loop 3.

[0032] In some embodiments, the movable plate 12 has a threaded hole, and the movable plate 12 is threadedly connected to the lead screw 11 through the threaded hole.

[0033] Under the interlocking force of the threaded hole and the lead screw 11, the movable plate 12 can be fixed after moving to a suitable position.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
