Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sintering trolley lubrication, in particular to a sintering trolley roller shaft in-service automatic oiling device and a use method thereof. BACKGROUND

[0002] In the steel smelting industry, the raw materials for blast furnace smelting need to go through a sintering step, mainly including: first, mixing crushed iron ore with fuel, solvent and water in a certain proportion to obtain a mixture; second, feeding the mixture into a sintering furnace for sintering. During the sintering process, a series of complex physical and chemical reactions occur between the materials, and the sintering blocks form the blast furnace smelting raw materials. The sintering trolley is mainly used to transport the mixture, starting from the material loading area and reaching the sintering furnace. The material is preheated, ignited, sintered, cooled, and turned over in the sintering furnace, and then the material is sent to the blast furnace area and returns to the material loading area to form a transmission cycle. The sintering trolley is mainly composed of a plurality of sintering trolleys connected end to end moving on a fixed track. Each sintering trolley includes a trolley body and a wheel system. The wheel system is composed of a shaft sleeve, a wheel shaft and a wheel. The shaft sleeve is welded to the trolley body, the wheel is installed on the wheel shaft through a bearing assembly, and the oil injection port at the center of the outer end face of the wheel shaft leads to the bearing assembly. Each sintering trolley has 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 dust particles, high temperature environment, etc. Particulate matter easily enters the bearing assembly to accelerate the wear of the wheel system, and high temperature reduces the viscosity of the lubricating oil to reduce the lubrication effect, also accelerating the wear of the wheel system. Therefore, the wear of the wheel system is a common fault of the sintering trolley, and adding lubricating oil to the sintering trolley wheel system to ensure the normal operation of the trolley has become an important work in the sintering operation of the steel industry.

[0003] Currently, there are three common lubricating oil filling methods in the industry. The first is manual filling of lubricating grease after the sintering trolley is stopped. This method has the following problems: the filling is not timely, the lubrication effect of the trolley is significantly attenuated under harsh working conditions, and severe wear of some wheel systems occurs after stopping for filling; the filling workload is large and the efficiency is low, and the wheel system of a large trolley is filled manually, which is a large workload; the stopping time is long, and a large amount of manual filling will significantly prolong the stopping time of the trolley, leading to excessive time consumption of the entire sintering operation and affecting the overall progress. The second is to integrate the oil filling robot into the sintering trolley, such as in document CN118636174A, an oil filling execution assembly is constantly filling oil to the wheels during the operation of the sintering trolley through the oil storage unit, pipeline system and oil filling execution assembly. This method also has the following problems: first, the oil filling robot integrated into the sintering trolley is equipped with an oil storage component, but after a period of service, it still needs to be stopped to deliver lubricating oil to the oil storage component. This method only reduces the stopping frequency of the trolley, but does not solve the problem of stopping the trolley. Second, the oil filling robot also needs to enter the sintering furnace and withstand the high temperature of sintering, which requires high temperature resistance of the robot, such as using high-cost heat-resistant alloy or adding heat insulation facilities. Third, the structure of the sintering trolley becomes complex, and if the oil filling robot needs to be repaired, it will increase the probability of stopping the trolley. The third is to arrange an automatic oil filling device in the sintering trolley operation site (area), such as the sintering trolley roller intelligent oil injection device disclosed in document CN215000893U, which can move synchronously with the sintering trolley to inject oil. In actual use, the injection nozzle adjusts the position up and down through a spring to adapt to the change of the sintering wheel oil injection port to ensure the oil injection effect. However, the injection nozzle cannot be adjusted in the horizontal direction, which still causes poor oil injection effect in actual use, and may even cause damage to the injection nozzle. Another document CN221705166U discloses a floating oil injection head suitable for the end of a robot, which allows the injection nozzle to move in four directions of up, down, front and back to adapt to the movement of the sintering trolley roller and the slight deviation of the sintering trolley roller oil injection port position. However, this device does not have the ability to automatically adjust large size position deviation, and is not convenient for accurate and automatic centering of the oil injection hole.

[0004] More importantly, the sintering trolley roller wear is continuously changing in actual production, and the existing scheme cannot monitor the wear change of the sintering trolley roller, and cannot accurately center and inject oil in the service of the oil injection hole for a long time.

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

[0060] The method for using the refueling device in Example 1 or Example 2 includes the following key steps:

[0061] Step 1: Control the clamping cylinder 6 to work, so that the two groups of L-shaped supports 7 move away 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;

[0062] Step 2: When the sintering trolley wheels move to the front between the two sets of L-shaped supports 7, the clamping cylinder 6 is controlled to work, so that the two sets of L-shaped supports 7 move closer to each other, so that the four runners 9 can clamp the sintering trolley wheels. The forward movement of the sintering trolley drives the oiling device to move forward synchronously.

[0063] Step 3, controlling the refueling device to refuel.

[0064] For example, the linear speed of the sintering trolley roller is V (uniform motion), when the sintering trolley roller is intact, the pressure value fed back by the four rotating wheels 9 when they tightly hold the roller and move with the sintering trolley is P0; when the sintering trolley roller has a worn area, the pressure value fed back by the rotating wheel A when it passes through the worn area is P1 (P0>P1) and the duration is t, then the length of the worn area is s=Vt.

[0065] Since the specific oiling device including the four rotating wheels 9 tightly holding the sintering trolley roller is adopted, the wear change of the sintering trolley roller can be monitored, the wear length of the sintering trolley roller in the corresponding time period can be calculated, the in-service accurate centering and oiling of the oil injection hole can be realized for a long time, and as long as the wear length does not exceed half of the arc length of the sintering trolley roller, the oiling can be performed, even if the sintering trolley shakes, the lubricating oil can be smoothly and stably injected. Since the oiling device with the specific structure protection assembly is adopted, the oil sludge attached to the roller shaft can be scraped off, and the attached oil sludge can be prevented from being pushed into the oil injection hole during the process of inserting the flexible oil injection head into the oil injection hole.
