Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a lifting device for a steel slag ladle. Background Art

[0002] During the smelting process of the AOD furnace in the steel mill, the steel slag is poured into the slag ladle. At this time, the temperature is above 1000°C. The slag ladle car is used to transport the steel slag to the slag ladle bay. After long-term high-temperature operation, the existing slag ladles are deformed greatly. It is often impossible to hook the existing fixed plate hooks, and it takes a long time for manual adjustment, which affects the production rhythm and cannot meet the production requirements. Using chain lifting cannot meet the production requirements of the steel eight production lines.

[0003] Based on this, the utility model designs a new type of slag ladle lifting device to solve the above problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a slag ladle lifting device, which can solve the problems existing in the prior art that due to the large deformation of the slag ladle, the fixed plate hook often cannot be hooked, it takes a long time for manual adjustment, which affects the production rhythm and cannot meet the production requirements, and using chain lifting cannot meet the production requirements of the steel eight production lines.

[0005] To solve the above problems, the technical solution of the utility model is: this kind of slag ladle lifting device includes a main beam and a secondary beam. The two ends of the main beam are respectively welded to the middle part of one secondary beam; a traveling crane hook ear for hooking up with a traveling crane is arranged in the middle of the main beam. A traveling crane hook ear pin and a traveling crane hook ear plate are installed on the top of the traveling crane hook ear. During use, the whole lifting device is hung on the traveling crane through the cooperation of the traveling crane hook ear, the traveling crane hook ear pin and the traveling crane hook ear plate; lifting lugs are arranged at both ends of the secondary beam, and the lifting lugs are hinged to the secondary beam.

[0006] In the above technical solution, a more specific solution is: both the main beam and the secondary beam are welded into square box girders with Q355B steel plates with a thickness of 20 mm.

[0007] Further: the traveling crane hook ear is welded to the main beam with a Q355B steel plate.

[0008] Further: the lifting lug is machined from a Q355B steel plate at one time.

[0009] Further: the lifting lug is hinged to the secondary beam through a lifting lug pin and a lifting lug plate.

[0010] Further: the traveling crane hook ear pin and the lifting lug pin are 8.8 - grade M18 screws machined from 45# steel.

[0011] Furthermore, both the lifting lug card plate and the overhead crane hook ear card plate are made of Q235B steel plate through one-time processing.

[0012] Furthermore, the axial distance between the two lifting lug pins hinged to the secondary beam on the same secondary beam is 1350 mm; the distance between the opposite lifting lugs on the two secondary beams is 3178 mm.

[0013] Due to the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] 1. The utility model adopts adjustable lifting lugs, which can adapt to various deformed slag ladles, thus reducing the problem of difficult hooking of the slag ladle during lifting, or the violation of the eight steel regulations by using chain lifting due to large deformation.

[0015] 2. The utility model adopts box-shaped main beams and secondary beams to increase the strength of the lifting appliance. At the same time, the main body material with stronger corrosion resistance of Q355B is used to improve the service life of the lifting appliance and reduce the replacement frequency; cost reduction and efficiency increase are achieved.

[0016] 2. The lifting device of the utility model is made of welded steel plates and is connected by pins, which is convenient for disassembly and avoids repeated welding during installation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the utility model in conjunction with the drawings and embodiments:

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4The slag ladle lifting device includes a main beam 1 and a secondary beam 2. Both the main beam 1 and the secondary beam 2 are welded into square box girders using Q355B steel plates with a thickness of 20 mm to reduce deformation. The two ends of the main beam 1 are respectively welded to the middle of a secondary beam 2. A traveling hook ear 4 for hanging connection with the overhead crane is provided in the middle of the main beam 1. A traveling hook ear pin 5 is inserted through the top of the traveling hook ear 4. Both ends of the traveling hook ear pin 5 are provided with traveling hook ear plates 8. During use, the entire lifting device is hung on the overhead crane through the cooperation of the traveling hook ear 4, the traveling hook ear pin 5, and the traveling hook ear plates 8.
