Product introduction
The metallurgical casting crane is one of the main equipment in the steelmaking and continuous casting process. It is mainly used to mix molten iron in the converter charging span, to lift the molten steel to the refining furnace in the refining span, or to lift the molten steel to the continuous casting rotary ladle table in the molten steel span. The overall structure of the metallurgical casting crane can be divided into double beams, double rails, four beams, four rails, four beams and six rails. The double-girder double-rail and four-girder four-rail forms are generally used for medium and large tonnage casting cranes, while the four-girder and six-rail double trolley forms are generally used for extra-large tonnage casting cranes. It is mainly composed of the bridge main and auxiliary trolleys and the trolley operating mechanism, the driver's cab device, the lubrication system, the electrical control system, etc. The casting crane is one of the main production equipment in the smelting workshop. In the converter workshop, the crane is used to pour the molten iron transported from the blast furnace workshop into the mixing furnace and directly pour the molten iron in the mixing furnace or the molten iron transported from the blast furnace workshop. Converter, this crane is equipped with independently driven main and auxiliary trolleys. The main trolley is equipped with fixed-spaced gantry hooks to lift steel drums. The auxiliary trolley can be used to tip steel drums or perform other auxiliary lifting operations.
●Cart operating mechanism
The driving mode of the cart operating mechanism adopts twelve-wheel drive (/adopts eight-wheel drive). It is composed of electric motor, hydraulic push rod brake, universal shaft, hard tooth surface reducer, wheel set, etc. The wheels have a double rim structure. The cart buffer adopts sleeve spring type buffer.
●Bridge structure
The bridge is divided into main beam, sub-main beam and end beam. The main beam adopts a wide deflection box beam, which has good vertical and horizontal stiffness, and is made of steel. In order to avoid fatigue damage of the main beam caused by concentrated wheel pressure, profiled steel is used under the track, which greatly increases the life of the main beam. There are two longitudinal reinforcements in the pressure area of the main beam. The auxiliary main beam adopts a normal box beam. A walking platform and protective railings are added to the outside of the beam. The end beam is a box-shaped structure. The auxiliary main beam and end beam adopt foreign four-beam connection structure, which reduces the number of end beam segments and improves the performance of the end beam. The trolley rail adopts a welded joint integral track, which greatly reduces the impact caused during the operation of the trolley. The lower part of the main beam is equipped with a heat insulation device. In order to allow the electronic control equipment to work in a suitable environment, the four walls of the main beam electrical room are sealed with heat insulation layers and a special axial flow fan for metallurgical applications is installed indoors to ensure that the crane operates in good condition. Operate in an environment to improve overall machine performance. The main beam, sub-main beam and end beam are connected by high-strength bolts. The trolley operating mechanism and main electronic control equipment are installed in the main beam. The overall structure is compact and the appearance is beautiful.
●Main trolley lifting
The main trolley lifting mechanism is composed of two electric motors, two floating shafts, two reducers with ratchet pawls, four hydraulic single push rod brakes, a reel set, a wire rope gantry hook set. Pulley block and other components. In addition to meeting the thermal overload requirements, the lifting motor also takes into account the special working conditions of the casting crane. The total power of the motor meets the static power requirements, ensuring that when one motor fails, the other motor can work for a short time to complete a job. cycle. The main hoisting reducer adopts a special hard-tooth reducer for foundry cranes. This reducer adopts a welded shell and has better performance than the special medium-tooth surface reducer for cranes promoted by the state. It is specially designed and manufactured for foundry cranes.
●Auxiliary trolley lifting
The auxiliary trolley lifting is composed of an electric motor, a hydraulic push rod, a brake, a floating shaft, a hard-toothed reducer, a drum set, a hook set, a fixed pulley set, etc. The operation of the auxiliary trolley adopts centralized drive, which is composed of electric motor coupling, hydraulic single push rod brake, transmission shaft reducer, active wheel set and passive wheel set. The wheels adopt a double rim structure.
●Driver's Cab
The driver's cab adopts a double-wall closed and insulated type with good visibility. A layer of anti-radiation board is added under the bottom. The windows are sliding windows for wiping off dust. They are equipped with tempered glass and built-in control mechanism. The linkage platform is easy to operate and has a comfortable environment. The cab is equipped with an air conditioner (the size of the air conditioner is determined according to the volume of the cab). There is a power supply in the cab, with two-phase and three-phase sockets. The ground is laid with insulated wooden floors. There is a fire extinguisher in the cab.
●Components
The main hoisting motor adopts a series of metallurgical and hoisting three-phase asynchronous motors, with an overspeed switch at the tail. The insulation level is level 1, and the protection level is rated voltage and frequency. This kind of motor has large overload capacity and good mechanical strength, and is suitable for starting equipment that frequently starts and brakes, is sometimes overloaded, and has significant vibration and impact. When it comes to motor selection, we select motors according to design specifications, heat generation, and overload checks to ensure users can use them. The hydraulic brake is a series of hydraulic single push rod normally closed type (/adopted type). This brake has the advantages of safe and reliable operation, smooth descending action, long service life and convenient maintenance. The technical level of the brake meets the standard of block brake. The reducer used for lifting is I The company directly purchases it from domestic famous brand manufacturers. It is a special reducer for metallurgy. It adopts a welded shell. The gears are made of high-quality high-strength low-carbon alloy steel, which has been carburized and quenched and ground. The tooth surface has high hardness, the gear precision is high, and the whole machine has a compact structure. , high load-bearing capacity and long service life. The lifting hook complies with the national standard lifting hook.
