Description

Technical Field

[0001] The utility model relates to the technical field of oil injection equipment, in particular to an automatic centering component of an oil injection system. Background Art

[0002] In the steel industry, sintering is an indispensable step. Before the blast furnace ironmaking production, various powdered iron-containing raw materials are mixed with appropriate amounts of fuel and flux, and appropriate amounts of water are added. After mixing and pelletizing, the materials undergo a series of physical and chemical changes on the sintering equipment, sintering into blocks to form raw materials for ironmaking. The sintering trolley is a device for transporting sintering raw materials. The sintering trolley forms a running rotary chain between the head and tail wheels of the sintering machine. The sintering raw materials are loaded in the sintering trolley carriage. After preheating, ignition, sintering, cooling, and turning, they are sent to the blast furnace area and return to the head wheel to form a transmission cycle. The sintering trolley is usually composed of sintering carts connected end to end on a track. Each sintering trolley includes a trolley carriage 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, and the wheel is installed on the wheel axle through a bearing assembly. The oil filling port on the outer end face of the wheel axle leads to the bearing assembly. The wheel can provide sufficient loading capacity for the vehicle model. The sintering trolley has dozens to hundreds of sets of the above-mentioned wheel systems, which run smoothly on the track through these wheel systems, thereby ensuring the operation of the entire sintering trolley.

[0003] In production, the wheel system of the sintering trolley is prone to failure due to its heavy load and long-term operation. In order to ensure safe production, it is necessary to lubricate the wheels of the sintering trolley with grease. The current method of lubricating the sintering trolley is to manually add grease after the sintering trolley is stopped. However, the dust caused by iron powder and iron chips during the operation of the sintering trolley, as well as the dry matter formed by the lubricating oil mixed with dust under high temperature conditions, are easy to enter the bearing assembly along the filling port during the injection of lubricating oil. It is not only easy to cause the bearing assembly to be not lubricated properly, but also cause the wear of the wheel axle. In addition, the sintering trolley in a hot operating environment is more likely to cause the deformation of the sintering trolley wheel under the condition of wheel system wear, accelerate the wear of the axle, and finally cause the wheel to lock, and the wheel has to be replaced. How to prevent the wear and damage of the wheel system caused by impurities such as iron powder and iron chips at a lower cost without affecting the operation of the wheel system of the sintering trolley, ensure sufficient lubrication of the wheel system, and reduce the maintenance and repair costs of the wheel system is a technical problem that needs to be solved urgently by technical personnel in this field.

[0004] With the development of technology, some equipment for automatically lubricating the wheels of sintering trolleys has emerged. For example, the utility model patent with authorization announcement number CN215000893U discloses an intelligent oiling device for sintering trolley wheels, which can be oiled as the sintering trolley moves synchronously. However, in actual use, the 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 adjusted in the horizontal direction, so that in actual use, the oiling effect is still poor, and serious damage to the oiling nozzle may occur.
