The furnace dismantling machine is mainly an important equipment for removing steel slag at the converter mouth. It can complete the dismantling operation accurately, efficiently and stably, and its structural configuration plays a crucial role. Below is an introduction to the structural composition of this LB140 Furnace Dismantling Machine.
Structural Introduction
Travel Drive Device
This machine adopts a crawler-type travel device. This mechanism is required to bear a large machine weight, have strong climbing ability, low ground pressure, stable travel, and can adapt to steep slope driving and sharp turns. The travel device is equipped with two crawlers, each driven independently by two sets of drive devices, enabling the entire machine to move forward, backward, turn, and also rotate in place. The operation is simple and flexible. The drive device uses an integrated travel motor, which features a compact structure, convenient maintenance, small space occupation, large ground clearance of the chassis, and a long service life.
Crawler Tensioning Device
The crawler tensioning device is composed of an idler wheel, a tensioning spring, a tensioning cylinder, and other components. This device is mainly used to maintain a certain tension of the crawler, thereby playing a buffering role during operation and travel. To adjust the tension, it is only necessary to inject (or discharge) grease with a grease gun.
Top Rollers and Track Rollers
These rollers adopt a single-sided structure, which not only meets the requirement of preventing the track from coming off but also minimizes the energy loss during the energy transmission process of the track.
Crawler Assembly
The travel track adopts a standard excavator-specification chain with a pitch of 190. The crawler uses three-rib crawler plates formed by rolling. These crawler plates have the advantages of high strength, good wear resistance, strong climbing ability, and low damage to the ground.
Travel Frame
The travel frame adopts an "X"-shaped welded rigid frame body, which has good rigidity, strong torsion resistance, and small deformation.
Main Oil Circuit System
This machine adopts the currently commonly used domestic hydraulic pilot control system and a negative flow sensing constant power variable system. It can automatically adjust the displacement and pressure of the pump according to changes in external load, enabling full utilization of engine power and minimizing fuel consumption.
Pilot Control System
This machine adopts hydraulic pilot operation. It uses a pilot valve to control the main directional control valve, ensuring light and flexible operation, and can realize proportional control of movement speed, which is conducive to shortening the switching time of the main valve core and reducing the labor intensity of the operator. The system is equipped with overload valves and oil make-up valves in all pipelines, and a braking device is installed on the travel reducer to achieve parking braking.
Cooling System
To prevent excessive oil temperature in the hydraulic system under high-temperature operating environments, maintain the good performance of hydraulic oil, and improve work efficiency, an independent hydraulic oil cooling system is adopted to effectively reduce system heat generation. This ensures that the system works within an appropriate temperature range, effectively reducing engine energy consumption and improving the service life and stability of hydraulic oil and hydraulic components.
Power System
The power source of this machine adopts a water-cooled Dongkang engine, which has the advantages of low fuel consumption, low noise, low pollution, and easy cold-starting. The diesel engine foot is flexibly connected to the platform through a shock absorber to reduce the vibration of the machine; the oil pump is connected to the engine through an elastic coupling, thereby extending the service life of the hydraulic pump.
Key Terminology Explanation
crawler-type travel device：Engineering machinery-specific travel structure, different from wheeled devices, with stronger adaptability to complex terrains (such as construction sites, slag yards), which is accurately reflected in the translation.
negative flow sensing constant power variable system：Follows the professional terminology of the hydraulic industry, accurately expressing the core working principle of the system (adjusting output based on load changes to save energy).
three-rib crawler plates："Three-rib" directly corresponds to the structural feature of the crawler plate (three reinforcing ribs on the surface), and "formed by rolling" clarifies the manufacturing process, ensuring the accuracy of technical details.
water-cooled Dongkang engine："Dongkang" (short for Dongfeng Cummins, a well-known domestic engine brand) is retained as a proper noun, and "water-cooled" clearly indicates the cooling method, conforming to the expression habit of mechanical product specifications.
