An anti-deformation electromagnetic gripping device for hoisting large cut steel plates.

Abstract

This utility model discloses an anti-deformation electromagnetic gripping device for hoisting large cut steel plates. It features a central electromagnet with a lifting ring at its top. Four antennae extend radially outward from the outer wall of the central electromagnet, each antennae having an antennae electromagnet at its outer end. The control circuitry for each antennae electromagnet is arranged along its corresponding antennae. This utility model still uses an electromagnet to grip and transfer the steel plate, but adds four antennae electromagnets around its perimeter. This allows the four antennae electromagnets to extend further and simultaneously grip the steel plate, avoiding point-to-point gripping and achieving overall gripping of the steel plate to prevent deformation.

Description

Technical Field

[0001] This utility model relates to the technical field of steel plate hoisting and transfer equipment in steel structure production workshops, and in particular to an anti-deformation electromagnetic gripping device for hoisting large cut steel plates. Background Technology

[0002] In steel component production workshops, one of the most basic processes is steel plate cutting. Basic steel plates are cut into different sizes and then processed through techniques such as assembly, stacking, rolling, and welding to create various steel components. The thickness of the basic steel plates varies, ranging from a few millimeters to a few centimeters. After cutting, the steel plates are transported to different processing equipment for further processing. Electromagnets are frequently used for transport and hoisting. Generally, an overhead crane lifts the electromagnet, which in turn lifts the steel plate, transporting it in the air. However, for transporting slightly larger, thinner steel plates, since the electromagnet only suspends one point, the steel plate's perimeter deforms due to its own weight during air transport. Although this deformation is small, even minor dimensional changes can negatively impact the assembly and welding dimensions later. Therefore, equipment is used to properly level and straighten the steel plates, complicating the processing. Reducing the impact of deformation during hoisting would significantly improve the efficiency of component production. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned situation by providing an anti-deformation electromagnetic gripping device for hoisting large cut steel plates. This gripping device improves the performance of existing electromagnetic gripping equipment.

[0004] The specific solution of this utility model is: an anti-deformation electromagnetic gripping device for hoisting large cut steel plates, which has a central electromagnet, a lifting ring on the top of the central electromagnet, and four tentacle rods arranged radially outward on the outer side wall of the central electromagnet. Each tentacle rod has a tentacle electromagnet at its outer end, and the control circuit of each tentacle electromagnet is arranged along the corresponding tentacle rod.

[0005] Furthermore, in this utility model, the bottom surfaces of the central electromagnet and the antennae electromagnet are both arranged horizontally, wherein the bottom surface of the antennae electromagnet is set 0.5cm to 0.8cm higher than the bottom surface of the central electromagnet.

[0006] Furthermore, in this invention, reinforcing ribs are welded between two adjacent antennae rods, and the four reinforcing ribs together form a rectangular reinforcing frame.

[0007] Furthermore, in this invention, a junction box is provided on each of the front and rear side walls of the central electromagnet. The control lines of the two front-mounted tentacle electromagnets are pulled along their corresponding tentacle rods to the front junction box, and the control lines of the two rear-mounted tentacle electromagnets are pulled along their corresponding tentacle rods to the rear junction box. The control lines in the junction boxes are pulled outward together with the control lines of the central electromagnet and connected to the controller.

[0008] Furthermore, the central electromagnet and the antennae electromagnet described in this utility model are both disc-shaped high-power electromagnets.

[0009] This utility model has the following beneficial effects:

[0010] 1. This utility model still uses electromagnets to grip and transfer steel plates, but it adds four additional electromagnets around the perimeter. This allows the four electromagnets to extend a greater distance and simultaneously attract the steel plate, avoiding the situation of attracting only one point and achieving overall gripping of the steel plate to prevent deformation.

[0011] 2. In this utility model, the bottom surface of the tentacle electromagnet is set 0.5cm to 0.8cm higher than the bottom surface of the central electromagnet. This way, when the four tentacle electromagnets attract the steel plate, they can attract the steel plate slightly upwards by a certain distance, which can better prevent the steel plate from deforming due to its own weight.

In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] See Figure 1 , Figure 2 This utility model is an anti-deformation electromagnetic gripping device for hoisting large cut steel plates. It has a central electromagnet 4, a lifting ring 3 on the top of the central electromagnet, and four antenna rods 6 arranged radially outward on the outer wall of the central electromagnet. Each antenna rod has an antenna electromagnet 7 at its outer end. The control circuit of each antenna electromagnet is arranged along the corresponding antenna rod.

[0019] Furthermore, in this utility model, the bottom surfaces of the central electromagnet and the antennae electromagnet are both arranged horizontally, wherein the bottom surface of the antennae electromagnet is set 0.5cm to 0.8cm higher than the bottom surface of the central electromagnet.

[0020] Furthermore, in this utility model, a reinforcing rib 5 is welded between two adjacent antennal rods, and the four reinforcing ribs together form a rectangular reinforcing frame.

[0021] Furthermore, in this utility model, a wire box 2 is provided on each of the front and rear side walls of the central electromagnet. The control lines of the two front-end electromagnets are pulled along the corresponding antenna rods to the front wire box, and the control lines of the two rear-end electromagnets are pulled along the corresponding antenna rods to the rear wire box. The control lines 1 in the wire box are pulled outward together with the control lines of the central electromagnet and connected to the controller.

[0022] Furthermore, the central electromagnet and the antennae electromagnet described in this utility model are both disc-shaped high-power electromagnets.

[0023] This utility model is a practical tool used as part of a lifting device. The lifting rings are connected to a gantry crane. When lifting steel plates, see [reference needed]. Figure 3 As shown, the central electromagnet is placed in the middle of the steel plate, and the other four tentacle electromagnets face the four directions. When the electromagnets are energized, they generate a suction force to lift the steel plate. Due to the action of the four tentacle electromagnets, the steel plate suspended in the air is less prone to large deformation. If the tentacle rods are designed to be longer, this deformation will be even less likely to occur. Moreover, if the size of the steel plate is slightly smaller, the anti-deformation effect will be more obvious.

[0024] In this invention, all four antenna rods are made of sturdy steel pipe material, and with the reinforcement of the reinforcing ribs, the auxiliary hoisting effect of the four antenna electromagnets is more obvious.

[0025] In this invention, during the design and manufacturing process, the control circuits of the four tentacle electromagnets are routed along the tentacle rods into the junction box to protect the control circuits, and then pulled out together.

[0026] This invention still uses electromagnets to grip and transfer steel plates, but it adds four additional perimeter electromagnets. These perimeter electromagnets can extend a greater distance to simultaneously grip the steel plate, avoiding point-based gripping and achieving overall gripping to prevent deformation. In this invention, the bottom surface of the perimeter electromagnets is 0.5cm to 0.8cm higher than the bottom surface of the central electromagnet. This allows the four perimeter electromagnets to hold the steel plate slightly higher when gripping it, further preventing deformation caused by the steel plate falling under its own weight.
