Description

Technical Field

[0001] This application relates to the field of transfer technology, and more particularly to a hoisting tool. Background Technology

[0002] The production and processing of steel ingots involves multiple processes. In order to facilitate the transfer of steel ingots between different processes, lifting tools are required. Currently, most steel ingots are lifted by attaching slings to their ends or sides, or by directly using electromagnetic chucks to pick them up. However, the stability and reliability of the above two methods are poor and they are prone to safety accidents. Therefore, it is necessary to make improvements. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides a lifting tool that utilizes an L-shaped rod to assist a suction cup in adsorption and lifting, thereby improving its safety and stability.

[0004] To achieve the above objectives, the present invention employs the following technology: A lifting tool includes a suction cup, a support rod, and an L-shaped rod. The support rod array is arranged around the suction cup. The top of the L-shaped rod is hinged to one end of the support rod, and the bottom surface of the L-shaped rod is an inclined surface that slopes upward toward the axis of the suction cup. A roller is provided at the bottom of the L-shaped rod. The hinge axes of the roller and the L-shaped rod are both parallel to the tangential direction of the suction cup, and the hinge axis of the roller is located outside the hinge axis of the L-shaped rod.

[0005] The beneficial effects of this utility model are as follows: the L-shaped rod serves as a support and protective component to assist the suction cup in completing the adsorption and hoisting, thereby preventing the steel ingot from falling during the transfer process and improving its hoisting safety.

[0009] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0010] This application provides a hoisting tool, such as... Figure 1 and Figure 2As shown, the device includes a suction cup 1, support rods 2, and L-shaped rods 3. The support rods 2 are arranged in an array around the suction cup 1. The top of the L-shaped rods 3 is hinged to one end of the support rods 2, and the bottom surface of the L-shaped rods 3 is an inclined surface sloping upwards towards the axis of the suction cup 1. A roller 4 is provided at the bottom of the L-shaped rods 3. The hinge axes of the rollers 4 and the L-shaped rods 3 are both parallel to the tangential direction of the suction cup 1, and the hinge axis of the rollers 4 is located outside the hinge axis of the L-shaped rods 3. In this embodiment, the suction cup 1 is an electromagnetic suction cup, and four support rods 2 are arranged in a circumferential array around the suction cup 1, making it suitable for both rectangular and cylindrical steel ingots.

[0011] When in use, move the tool above the steel ingot and then lower it. After the roller 4 contacts the ground, the L-shaped rod 3 will rotate outward until the suction surface of the suction cup 1 contacts the top surface of the steel ingot. Make the suction cup 1 work, and after completing the suction of the steel ingot, move it up to a certain height and then transfer it. During this process, the L-shaped rod 3 will rotate inward under the action of gravity and return to the vertical state.

[0012] It should be noted that when the L-shaped rod 3 is in a vertical state, there are predetermined gaps between its vertical section and the side of the steel ingot, and between its horizontal section and the bottom of the steel ingot. This is to allow for the rotation space of the L-shaped rod 3, and also to show that the L-shaped rod 3 exists as a protective measure for lifting tools. When the suction cup 1 is unstable, it can be used to support the steel ingot and prevent it from falling.

[0013] To improve the stability of the tool and prevent the L-shaped rod 3 from shaking during the transfer of the steel ingot, preferably, as follows: Figure 1 and Figure 2 As shown, a spring plate 5 is provided at the rotatable connection between the L-shaped rod 3 and the support rod 2.

[0014] Preferred, such as Figure 1 and Figure 2 As shown, the top surface of the L-shaped rod 3 horizontal section is provided with anti-wear strips.

[0015] In application, the above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
