Description
Technical Field
[0001] The utility model relates to the technical field of oil injection equipment, in particular to an oil injection mechanism. 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 the wheels of sintering trolleys, which can be oiled synchronously with the movement of the sintering trolley. However, in actual use, its oiling mechanism adopts a linear module, a first fixed plate and a second fixed plate to connect the oiling nozzle to carry out the oiling process, which has the problems of complex structure, high failure rate and poor linear operation status.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] The oil injection mechanism in the embodiment of the utility model maintains a good oil injection effect while simplifying the structure through the cooperation of the support frame, the cylinder and the oil injection nozzle assembly.
[0030] like Figure 1 - Figure 7 As shown, the oiling mechanism includes a support frame 1, a cylinder 2 and an oiling nozzle assembly 3. The cylinder 2 is arranged at one end of the support frame 1, and the oiling nozzle assembly 3 is slidably arranged at the other end of the support frame 1. The cylinder 2 can drive the oiling nozzle assembly 3 to extend and retract, so as to oil the wheels of the sintering trolley. A guide cylinder 11 is arranged on the support frame 1. The oiling nozzle assembly 3 includes a support cylinder 31 and an oiling nozzle 32. The oiling nozzle 32 is arranged at one end of the support cylinder 31, and the other end of the support cylinder 31 is connected to the cylinder 2. At the same time, the support cylinder 31 is slidably arranged in the guide cylinder 11.
[0031] Through the above arrangement, compared with the existing oiling mechanism, the integration is improved, the cylinder 2 as the driving device and the oiling nozzle assembly 3 for oiling are both arranged on the support frame 1, and the overall structure is compact. At the same time, through the cooperation of the support cylinder 31 and the guide cylinder 11, the movement of the support cylinder 31 is more stable and the guiding effect is good, so that the oiling nozzle 32 can be better aligned with the oiling port of the sintering trolley wheel.
[0032] Specifically, the support frame 1 includes a first support plate 12, a second support plate 13 and a side plate 14. The first support plate 12 and the second support plate 13 are arranged at intervals, the side plate 14 is arranged between the first support plate 12 and the second support plate 13, the guide cylinder 11 is arranged on the first support plate 12, and the cylinder 2 is arranged on the second support plate 13.
