Description

Technical Field

[0001] The invention relates to the technical field of lubrication of a sintering trolley, and in particular to an in-service automatic oiling device for a roller shaft of a sintering trolley and a use method thereof. Background Art

[0002] In the steel smelting industry, the raw materials for blast furnace ironmaking need to go through a sintering step, which mainly includes: first, mixing the crushed iron ore with fuel, solvent and water in a certain proportion to obtain a mixed material; second, sending the mixed material to the sintering furnace for sintering. During the sintering process, a series of complex physical and chemical reactions occur between the materials, sintering blocks, and forming blast furnace ironmaking raw materials. The sintering trolley is mainly used to transport the mixed material, starting from the material loading area and arriving at the sintering furnace. After the material is preheated, ignited, sintered, cooled, and turned over in the sintering furnace, the material is sent to the blast furnace area and returned to the material loading area to form a transmission cycle. The sintering trolley is mainly composed of multiple sintering trolleys connected end to end and moving on a fixed track. Each sintering trolley includes a car body and a wheel system. The wheel system consists of a bushing, a wheel axle and a wheel. The bushing is welded to the trolley body. The wheel is installed on the wheel axle through the bearing assembly. The oil filling port in the center of the outer end face of the wheel axle leads to the bearing assembly. Each sintering trolley is composed of several wheel systems, and each sintering trolley includes hundreds of wheel systems. When the sintering trolley passes through the material loading area and the sintering furnace, there are harsh conditions such as ore dust particles and high temperature environment. Particles can easily enter the bearing assembly and accelerate the wear of the wheel system. High temperature will reduce the viscosity of the lubricating oil and reduce the lubrication effect, which also accelerates the wear of the wheel system. Therefore, the wear of the wheel system is a common fault of the sintering trolley, and filling the roller system of the sintering trolley with lubricating grease to ensure the normal operation of the trolley has become an important task in the sintering operation of the steel industry.

[0003] At present, there are three common ways of filling lubricating grease in the industry. The first is to manually add grease after the sintering trolley stops. The problems with this method include: the filling is not timely, the lubrication effect of the trolley is significantly reduced under harsh working conditions, and it is very easy to wear. If it is filled after stopping, some wheel systems will be severely worn; the filling workload is large and the efficiency is low. Large trolleys have many wheel systems and rely entirely on manual filling, which is a large workload; the parking time is long, and a large amount of manual inefficient filling will significantly extend the parking time of the trolley, causing the entire sintering operation to take too much time and affect the overall progress. The second is to integrate the refueling robot into the sintering trolley. For example, in the document CN118636174A, through the oil storage unit, the pipeline system, and the refueling actuator, the refueling actuator continuously refuels the wheels during the operation of the sintering trolley. This method also has the following problems: First, although the refueling robot integrated into the sintering trolley is equipped with an oil storage component, it still needs to stop to deliver lubricating oil to the oil storage component after serving for a period of time. This method only reduces the frequency of the trolley's parking, and does not solve the problem of the trolley's need to stop; second, the refueling robot also needs to enter the sintering furnace, withstand the high temperature of sintering, and has high requirements for the robot's temperature resistance, such as using high-cost heat-resistant alloys or adding insulation facilities; third, the structure of the sintering trolley becomes complicated. If the refueling robot has a problem and needs to stop for maintenance, the probability of stopping is virtually increased. The third is to arrange an automatic refueling device at the sintering trolley operation site (area), such as the sintering trolley roller intelligent oiling device disclosed in document CN215000893U, which can be oiled with the synchronous movement of the sintering trolley. In actual use, its oiling nozzle is adjusted up and down by a spring, so as to adapt to the changes in the oiling port of the sintering wheel to ensure the oiling effect. However, the oiling nozzle cannot be aligned in the horizontal direction, so that in actual use, there is still a problem of poor oiling effect, which may seriously cause damage to the oiling nozzle. Another document CN221705166U discloses a floating oiling head suitable for the robot end. By setting a centering component, a first spring component and a second spring component, the oiling nozzle is allowed to move in four directions, up and down, front and back, to adapt to the movement of the sintering trolley roller and the slight offset of the position of the sintering trolley roller oiling port. However, the device does not have the ability to automatically adjust large-scale position offsets, and is not convenient for accurate and automatic centering of the oiling hole.

[0004] More importantly, the wear of the sintering trolley rollers changes continuously during the actual production process, and the existing solutions cannot monitor the wear changes of the sintering trolley rollers, and cannot achieve long-term precise in-service centering and oiling of the oiling holes.

When the four rotating wheels 9 hold the rollers of the sintering trolley tightly, the oiling device is driven to move forward synchronously only by the forward movement of the sintering trolley.

[0030] The method for using the refueling device in Example 1 or Example 2 includes the following key steps: Step 1, control the clamping cylinder 6 to work, so that the two groups of L-shaped supports 7 are separated from each other. In this case, the distance between the two groups of L-shaped supports 7 is greater than the outer diameter of the sintering trolley roller; Step 2: When the rollers of the sintering trolley move to the front between the two groups of L-shaped supports 7, the clamping cylinder 6 is controlled to work, so that the two groups of L-shaped supports 7 are close to each other, so that the four wheels 9 clamp the rollers of the sintering trolley, and the oiling device is driven to move forward synchronously by the forward movement of the sintering trolley; Step 3, controlling the refueling device to refuel.

[0031] Taking Example 2 as an example, when it is necessary to measure the wear length of the sintering trolley roller in the corresponding time period, it is only necessary to first calculate the linear velocity of the sintering trolley roller, and based on the duration of the specific pressure value fed back by the pressure sensor on the wheel, the wear length of the sintering trolley roller in the corresponding time period can be calculated. For example: the linear velocity of the sintering trolley roller is V (uniform motion), when the sintering trolley roller is intact, the four wheels 9 are tightly clamped on the roller and the pressure value fed back when the sintering trolley is running is P0; when the sintering trolley roller has a wear area, the pressure value fed back when the wheel A passes through the wear area is P1 (P0>P1) and the duration is t, then the length of the wear area is s=Vt.

[0032] Since a specific refueling device including four wheels 9 is used to hold the rollers of the sintering trolley tightly, it is convenient to monitor the wear changes of the rollers of the sintering trolley, and it is convenient to measure the wear length of the rollers of the sintering trolley in the corresponding time period, which is conducive to the long-term accurate centering and oiling of the oil filling hole in service. As long as the wear length does not exceed half of the arc length of the sintering trolley roller, it can be filled, and even if the sintering trolley vibrates, it can be smoothly and stably filled with lubricating oil. Since a refueling device with a specific structural protection component is used, the sludge attached to the trolley roller shaft can be scraped off to prevent the attached sludge from being pushed into the oil filling hole during the insertion of the flexible oil filling head into the oil filling hole.
