Description

Technical Field

[0001] The utility model relates to the technical field of oiling of a sintering machine trolley, and more specifically to an automatic oiling and lubricating device for a sintering machine trolley. Background Art

[0002] Sintering machine is an important equipment for sintering iron ore powder in the metallurgical industry. It is widely used, and sintering trolley is an important part of sintering machine. In the production process, the wheel bearings of sintering machine trolley not only have to withstand high temperature, heavy load, impact vibration, dust and water shower and other harsh working conditions, but also have to withstand long-term alternating thermal stress. The working conditions are very bad, which causes the trolley to frequently drop wheels and axial movement. Therefore, the wheel bearings of the trolley need to be frequently replenished with lubricating grease to ensure its normal operation. However, production does not allow the sintering machine to stop frequently to refuel the wheels, resulting in poor lubrication of the wheel bearings of the trolley.

[0003] The automatic refueling device currently used adopts a mechanical arm to drive a movable grease gun head to track and refuel through image recognition. Since the trolley wheel not only moves linearly with the trolley track, but also rotates on the trolley track, there will be relative rotational movement between the oil nozzle and the gun head when the mechanical arm tracks and refuels, causing frequent damage to the oil nozzle or the gun head. In addition, there will be a lot of grease residue in the oil nozzle and the gun head after refueling, which drips on the working ground and is difficult to clean, affecting the appearance, polluting the environment, and increasing the consumption of grease. Therefore, an automatic refueling and lubrication device for a sintering machine trolley is proposed. Utility Model Content

The oil supply plunger rod 15 moves to squeeze the return spring 16, so that the lubricating oil in the plunger cavity 14 can be injected into the interior of the sintering machine trolley wheel 1 through the oil pipe 10.

[0029] As attached Figure 1 As shown, the detection and positioning mechanism 7 corresponds to the trolley oiler 2, the moving end of the oil-driving pneumatic cylinder 8 corresponds to the oil-driving plunger rod 15, and the moving end of the oil-driving pneumatic cylinder 8 is rotatably connected with an extrusion plate.

[0035] When the detection and positioning mechanism 7 detects that the sintering machine trolley wheel 1 corresponds to the detection and positioning mechanism 7, the main control device 4 sends a command to control the second support plate 6 to move on the top of the slide rail 5, so that the oil supply driving pneumatic cylinder 8 and the detection and positioning mechanism 7 always correspond to the sintering machine trolley wheel 1. At this time, the moving end of the oil supply driving pneumatic cylinder 8 corresponds to the oil supply plunger rod 15;

[0036] Then, the oil supply driving pneumatic cylinder 8 is started to push the oil supply plunger rod 15 repeatedly, and the lubricating oil in the oil storage bag 12 can be injected into the interior of the sintering machine wheel 1 through the oil pipe 10 through the plunger cavity 14 to complete the oil supply;
