[0004] However, when using this device to lift steel plates, the steel plates may be slightly bent and deformed in the middle due to their heavy weight; and the lifting ropes are prone to shaking, which may cause the steel plates to detach, posing certain safety hazards. Utility Model Content

[0005] Therefore, in order to solve the above problems, the present invention proposes a steel plate lifting beam tooling to solve the problem that the steel plate lifting beam tooling in the prior art is prone to shaking and falling off during the process of lifting the steel plate.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A steel plate hanging beam tool comprises a hanging beam body and a plurality of hanging components arranged on the hanging beam body.

[0008] The lifting assembly includes two lifting straps and two horizontal plate hooks.

[0017] 1. The utility model has a simple structure and is easy to operate. By setting a lifting beam main body and multiple sets of lifting components, it can effectively disperse the stress points of the steel plate, thereby protecting the steel plate and preventing it from deformation. The horizontal plate hook can clamp the steel plate by using a 匚-shaped hook and a connecting piece. When in use, the steel plate is placed on the inner bottom wall of the 匚-shaped hook. When the steel plate is lifted, the connecting piece is clamped downward by the lever action, thereby making the steel plate clamped more stably, without the need for manual locking, which is convenient and quick. By setting an anti-slip strip, the friction between the steel plate and the inner bottom wall of the 匚-shaped hook is increased, effectively reducing the risk of the steel plate slipping.

[0018] 2. By setting up an electromagnet, the middle of the steel plate can be adsorbed to further disperse the stress points of the steel plate, effectively preventing the problem of bending of the middle of the steel plate caused by excessive stress concentration on both sides of the steel plate. At the same time, the steel plate can be further fixed, thereby improving the stability of the steel plate hoisting, effectively avoiding the occurrence of steel plate slipping accidents caused by the shaking of the lifting rope, ensuring the safety of the steel plate hoisting operation, and strong practicality.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0025] refer to Figures 1 to 4 This embodiment provides a steel plate hanging beam tooling, including a hanging beam body 1 and a plurality of hanging components arranged on the hanging beam body 1.

[0026] The lifting assembly includes two slings 2 and two horizontal plate hooks 3. The two slings 2 are symmetrically installed on both sides of the bottom of the lifting beam body 1 through a first shackle. The lower end of the sling 2 is connected to the horizontal plate hook 3 through a second shackle; the two horizontal plate hooks 3 of each set of lifting assemblies are arranged opposite each other. The above-mentioned slings 2 are preferably steel wire ropes; the structures of the above-mentioned first shackle and second shackle are existing technologies and are not shown in the figure. Providing multiple sets of lifting assemblies can disperse the force of the slings 2 on the steel plate 7, play a role in protecting the steel plate 7 from deformation, and improve the stability of the lifting. 4-7 sets of lifting assemblies can be configured according to the length of the steel plate 7.

[0027] The top of the main beam 1 is symmetrically provided with a plurality of lifting lugs 4, and the lower middle portion of the main beam 1 is provided with at least one electromagnetic attraction assembly 5. The lifting lugs 4 are used to connect to a lifting device to lift the entire device. The electromagnetic attraction assembly 5 is used to magnetically attract the steel plate 7. The appropriate number of electromagnetic attraction assemblies 5 can be configured according to the length of the steel plate 7.

[0028] The electromagnetic adsorption assembly 5 includes a hydraulic telescopic cylinder 51 and an electromagnet 52. The hydraulic telescopic cylinder 51 is fixedly mounted at the bottom of the hanging beam. A fixing plate 53 is disposed above the electromagnet 52. The output end of the hydraulic telescopic cylinder 51 is fixedly connected to the upper end of the fixing plate 53. The fixing plate 53 and the electromagnet 52 are fixedly connected via a plurality of elastic members 54, preferably springs. By adjusting the hydraulic telescopic cylinder 51 to bring the electromagnet 52 into contact with the steel plate 7, the electromagnet 52 is activated to adsorb the middle portion of the steel plate 7. This further disperses the stress points of the steel plate 7, effectively avoiding the problem of excessive stress concentration on both sides of the steel plate 7, which may cause the middle portion of the steel plate 7 to bend. At the same time, the steel plate 7 is further fixed to prevent it from shaking, thereby improving the stability and safety of the steel plate 7 hoisting. The elastic member 54 acts as a buffer, ensuring that the electromagnet 52 and the steel plate 7 can be in contact at any time, and will not lose contact due to slight errors in the stress points of the horizontal plate hook 3 or slight shaking of the steel plate 7.

[0029] In this specific embodiment, a plurality of telescopic rods 55 are further provided between the fixed plate 53 and the electromagnet 52. The telescopic rods 55 include straight rods 552 and sleeves 551. The upper end of the sleeve 551 is fixedly connected to the fixed plate 53, and the lower end of the straight rod 552 is fixedly connected to the electromagnet 52. The upper end of the straight rod 552 is movably disposed within the sleeve 551. The provision of the telescopic rods 55 limits the horizontal position of the electromagnet 52 to prevent the electromagnet 52 from shaking left or right.

[0030] In this embodiment, the main beam 1 comprises two parallelepiped frames 11 and a plurality of parallel connecting plates 12 connecting the two frames 11. Ribs 13 are spaced apart on the outside of the frames 11 to reinforce the strength of the main beam 1. Connecting holes 14 are provided at the lower ends of the ribs 13, and the sling 2 is connected to the connecting holes 14 via a first shackle. This minimizes the weight of the main beam 1 while ensuring its structural stability.

[0031] In this specific embodiment, a pair of legs 6 are provided at the lower end of the suspension beam body 1. The legs 6 can be placed stably on the ground when not in use to protect the electromagnet 52 from being crushed.

[0032] In this specific embodiment, the horizontal plate hook 3 includes a ⌚-shaped hook 31 and a connector 32. The inner bottom angle of the ⌚-shaped hook 31 is 90°. The upper portion of the ⌚-shaped hook 31 is provided with a rotation slot (not shown in the figure). The middle portion of the connector 32 is rotatably disposed within the rotation slot via a pin 33. The upper end of the connector 32 is connected to the sling 2 via a second shackle. The ⌚-shaped hook 31 is used to engage with the edge of the steel plate 7, thereby lifting the steel plate 7. The connector 32 can rotate along the pin 33 to lower the steel plate 7, improving the lifting stability.

[0033] In this embodiment, a plurality of anti-slip strips 34 are provided on the inner bottom surface of the 匚-shaped hook 31. The anti-slip strips 34 are preferably made of rubber material, which can increase the friction between the steel plate 7 and the inner bottom wall of the 匚-shaped hook 31 and reduce the risk of the steel plate 7 slipping.

[0034] The working principle of this utility model is as follows:

[0035] When lifting the steel plate 7, move the lifting beam body 1 to above the steel plate 7, then engage the horizontal plate hooks 3 on both sides of the steel plate 7, and then lift the lifting beam body 1 upward to tighten the slings 2 on both sides. At this time, the connecting piece 32 clamps the steel plate 7 under the action of the lever, and then start the hydraulic telescopic cylinder 51 to the lower end of the electromagnet 52 to support the steel plate 7, and turn on the electromagnet 52 to adsorb the steel plate 7, thereby further improving the stability of the lifting of the steel plate 7.

[0036] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
