It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. The embodiments and features of the embodiments of the invention may be combined with each other without conflict.
Fig. 1 is a schematic plan view of a converter translation device according to an embodiment of the present invention.
Referring to fig. 1, the converter translation device according to the embodiment of the present invention includes a pair of rails 4 passing through a charging bay 1, a furnace bay 2, and a refining bay 3, a transportation device 5 having a lifting function and disposed on the rails 4 and movable along the rails 4, and a hoist 6 installed in the refining bay 3 and providing a traction force to the transportation device 5.
The main workshop of the converter steelmaking workshop adopts a multi-span adjoined arrangement form and sequentially comprises a charging span 1, a furnace span 2, a refining span 3 and a molten steel receiving span. A pair of rails 4 is installed on the ground foundation of the main workshop of the converter steelmaking workshop, and the pair of rails 4 at least penetrate through a charging span 1, a furnace span 2 and a refining span 3 in the main workshop of the workshop. The transport device 5 is disposed on the track 4 and can move along the track 4, and the winch 6 is used for providing traction force for the movement of the transport device 5.
After the maintenance of the converter in the charging bay 1 has been completed, the drag ring 15 and the furnace shell 16 of the converter are brought into position on the transport device 5, traction is provided by the hoist 6 to translate the transport device 5 into the installation position in the furnace bay 2, and then the drag ring 15 and the furnace shell 16 of the converter are brought down into position on the bearing block support by the lifting function of the transport device 5.
According to the converter translation device provided by the embodiment of the invention, the converter can be translated to the installation position and positioned on the bearing seat support without dismounting equipment such as a converter operation platform, so that the hoisting cost for dismounting equipment such as the converter operation platform in the prior art is effectively saved, the construction efficiency of converter replacement and maintenance is improved, and the problem of integral converter installation in a limited space is solved.
Fig. 2 shows a schematic illustration of the structure of the transport device 5.
Referring to fig. 2, in the converter translation device provided in the embodiment of the present invention, the transportation device 5 includes a ladle carriage 7 disposed on the rail 4 and movable along the rail 4, a steel frame 8 fixed on the ladle carriage 7, and four jacking assemblies disposed on the top of the steel frame 8; each jacking assembly comprises a hydraulic jack 9 and a steel support 10.
The ladle car 7 is also called a ladle car, and is an electric flat car with freely controllable running speed for transporting ladles in a steel plant. When the ladle trolley 7 is empty or has a small load, the ladle trolley 7 can be driven to move on the track 4 by using the power of the ladle trolley 7; when the load of the ladle carriage 7 is large, such as the drag ring 15 and the furnace shell 16 for transporting the converter, the ladle carriage 7 cannot move on the rail 4 by the power of the ladle carriage 7 itself, and at this time, the winch 6 mainly provides traction force to drive the ladle carriage 7 to move on the rail 4.
The maximum load of the ladle trolley 7 is larger than the weight of the drag ring 15 and the furnace shell 16 of the converter. Preferably, the ladle trolley 7 is formed by welding two ladle trolleys end to end. Therefore, the maximum load of each buggy ladle can be reduced, and the purchasing cost of a single buggy ladle is reduced.
For example, the heads and the tails of two ladle cars in a converter steelmaking workshop are temporarily welded together by adopting channel steel or I-steel and other section steel, so that the two ladle cars temporarily form a whole for transporting the converter; and after the converter is installed, removing the connecting piece between the two ladle cars.
The steel frame 8 is formed by welding profile steels and comprises eight stand columns arranged circumferentially, the lower end of each stand column is fixedly connected with the ladle trolley 7, and a support rod arranged in an inclined mode is welded between every two adjacent stand columns. 300t hydraulic jacks 9 are respectively placed at the tops of the four upright columns, and steel supports 10 are placed at the tops of the other four upright columns. When the towing ring 15 is in place on the steel frame 8, the towing ring 15 is supported by the four steel supports 10, and the four hydraulic jacks 9 are in an unstressed state, and the height of the bearing seat on the towing ring 15 is ensured to be 50-100mm higher than the bearing seat support in the furnace span 2.
According to the converter translation device provided by the embodiment of the invention, the ladle trolley 7 is provided with the first movable pulley block 11, and the refining span 3 is internally provided with the first fixed pulley block 12; after a steel wire rope 13 of the winch 6 bypasses the pulleys of the first fixed pulley block 12 and the first movable pulley block 11, the end of the steel wire rope 13 is fixed in the refining span 3.
The winch 6 is arranged on the ground foundation on one side of the inner track 4 of the refining span 3; in order to improve the installation firmness of the winch 6, the winch 6 is also connected with a plant stand column in the refining span 3 through a connecting device. And a steel wire rope 13 of the winch 6 is connected with the ladle trolley 7 through a pulley block. The pulley block comprises a first movable pulley block 11 and a first fixed pulley block 12; the first movable pulley block 11 is arranged at the end part of the ladle trolley 7 facing the refining span 3; the first set of stator pulleys 12 is mounted on the basis between two tracks 4 in the refining bay 3. After a steel wire rope 13 of the winch 6 bypasses the first fixed pulley block 12 and the first movable pulley block 11, the end of the steel wire rope 13 is fixed in the refining span 3. For example, the end of the steel wire 13 may be fixed to the ground base in the refining span 3, or may be fixed to a plant column in the refining span 3. Preferably, the end of the steel wire rope 13 is connected with a bracket of the first fixed pulley group 12.
The converter translation device provided by the embodiment of the invention can achieve the aim of saving labor by arranging the first movable pulley block 11 and the first fixed pulley block 12 which are matched with each other. For example, the first movable pulley block 11 and the first fixed pulley block 12 each comprise three pulleys. In this case, the hoisting machine 6 may be a 3-ton hoisting machine.
A redirection wheel 14 is also arranged in the refining span 3; the steel wire rope 13 of the winch 6 firstly bypasses the bend wheel 14 and then bypasses the pulleys in the first fixed pulley block 12 and the first movable pulley block 11. The direction-changing wheel 14 is arranged for changing the direction of the steel wire rope 13, and therefore the purpose of flexibly arranging the installation position of the winch 6 is achieved. The direction-changing wheel 14 may be one or more. The redirection wheel 14 can be installed on the ground base in the refining span 3, and also can be installed on a factory building upright post in the refining span 3.
The converter installation method provided by the embodiment of the invention,
the method comprises the following steps:
