Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lifting technology, specifically a metallurgical electromagnetic bridge crane. Background Technology

[0002] An electromagnetic bridge crane is a machine that uses electromagnetic principles to move steel items. The main component of an electromagnetic bridge crane is a magnet. When the current is turned on, the electromagnet generates a strong magnetic field, which can firmly attract iron sheets, wires, nails, scrap iron and other iron materials weighing tens of tons and lift them to the designated place. When the current is turned off, the magnetism disappears and the steel items are lowered. Electromagnetic bridge cranes are often used in the metallurgical industry because of their simple operation and easy handling.

[0003] There are many types of electromagnetic bridge cranes on the market today, which can basically meet people's needs. However, there are still some shortcomings. Existing electromagnetic bridge cranes generally do not have protective measures when in use. When the power is accidentally cut off, the electromagnet loses its magnetism, causing steel objects to fall off and causing accidents, which pose certain safety hazards. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a metallurgical electromagnetic bridge crane. It effectively solves the problem that existing electromagnetic bridge cranes generally lack protective measures during use, and when an unexpected power outage occurs, the electromagnet loses its magnetism, causing steel items to fall off and resulting in accidents and certain safety hazards.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A metallurgical electromagnetic bridge crane includes a frame, on which a lifting trolley movable along the frame is mounted. The lifting trolley is equipped with lifting equipment, which includes a lifting cable. The lower end of the lifting cable is connected to an integrally formed first and second frame plates. An electromagnet is mounted on the lower end of the second frame plate. A blocking structure is provided on the first and second frame plates, the blocking structure including several support rods that tend to move synchronously with the axis of the electromagnet.

[0007] Preferably, the blocking structure further includes a motor mounted on the first frame plate, the output end of the motor being provided with a turntable rotatably connected to the second frame plate, pins being evenly distributed at the non-center points of the turntable, a support rod being rotatably connected to the pin, a slider being rotatably connected to one end of the support rod and slidably connected to the inner wall of the second frame plate, limiting plates being provided at both ends of the slider and slidably connected to the second frame plate, a fixing rod being fixedly connected to the lower end of the slider, and a support rod being provided at the lower end of the fixing rod.

[0008] Preferably, a support frame is provided at the upper end of the first frame plate, and the suspension cable is installed on the support frame.

[0009] Preferably, the two ends of the lifting trolley are respectively driven by wheels connected to the frame, the lifting equipment is installed in the middle of the lifting trolley, and the lifting equipment includes a winch.

[0010] This utility model has a novel structure, ingenious design, and is simple and convenient to operate. Compared with the prior art, it has the following advantages:

[0011] During the rotation of the turntable, the support rods are driven to move synchronously through the pins. The support rods drive the corresponding sliders to slide along the inner wall of the second frame plate under the action of the limit plate. The sliders drive the fixed rods to slide, and the fixed rods drive the support rods to move synchronously to the center. The support rods support the lower end of the steel object. Compared with the mechanical gripper, it has stronger stability and better support effect, and can effectively avoid the risk of the electromagnet losing its magnetism and causing the steel object to fall off.
