Description

Technical Field

[0001] The invention relates to the technical field of sintering trolley oiling equipment, in particular to an automatic oiling and lubricating system for sintering machine trolley wheels. Background Art

[0002] Trolleys are used in the sintering production process of the metallurgical industry. Their moving parts are multiple sets of arranged wheels. High-temperature grease is usually used to lubricate the wheels, which firmly adheres to the inner surface of the wheels to form a stable oil film. The lubrication performance of the wheels can still be maintained under high temperature conditions. It will not evaporate or lose easily like low-viscosity lubricants. In order to avoid the danger of manual operation, the existing oil filling method includes mechanical automatic filling.

[0003] For example, the Chinese patent application number CN202310851887.4 discloses an online oiling robot device and method for sintering trolley wheels, including a reciprocating flexible oiling device, a tactile sensor, a working environment temperature sensor, and a computer intelligent control system. It drives the oiling device to swing back and forth through an oscillating cylinder, and realizes online oiling during production. It ensures the full lubrication requirements of the wheels through intelligent control, and the flexible oiling device can achieve the functions of accommodating deviation, tilt, and twisting of hundreds of oil holes through the set flexible oiling device. The whole can meet the flexible oiling function without wearing the oiling nozzle mechanism, ensuring zero leakage during oiling. However, under sintering conditions, the coke formed by the mixture of grease and dust will often clog the area around the wheel oiling port. The oiling amount controlled by the sensor in the oiling robot device is pressure-controlled. If there is a blockage around the wheel oiling port, it will cause abnormal oiling pressure. Therefore, there is a situation where the oiling is stopped if the oiling amount does not meet the standard, and the lubrication performance of the wheel cannot be guaranteed.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] The first aspect of the present invention provides an automatic lubrication system for sintering machine wheels. Figure 1-7 As shown, it includes a mounting frame 1 and a sliding seat 1 2 and a sliding seat 2 3 provided on the mounting frame 1. The sliding direction of the sliding seat 1 2 is perpendicular to the sliding seat 2 3. The sliding seat 2 3 is provided with an oil injection assembly. The automatic oiling and lubrication system also includes: The cylinder 4 is provided on the sliding seat 2, and the cylinder 4 is used to drive the oil injection assembly to move back and forth in the direction of the sintering machine wheel; A rotating cylinder 5 reciprocates on the oil injection assembly, and the rotating cylinder 5 is sleeved on the end of the oil injection assembly; A plurality of nozzles 7 are obliquely arranged on the rotating cylinder 5, and the ports of the nozzles 7 are all directed toward the oil injection end of the oil injection assembly; A transmission part for driving the rotating cylinder 5 to reciprocate on the oil injection assembly; A driving part for driving the sliding seat 2 to move back and forth.

[0022] In this embodiment, when in use, the driving unit drives the sliding seat 2 to move to match the traveling state of the sintering machine trolley, and the cylinder 4 drives the oil injection assembly to move back and forth in the direction of the sintering machine trolley. Under the two-way movement, the oil injection end of the oil injection assembly automatically connects with the oil receiving port of the sintering machine trolley; At the same time, the output end of the cylinder 4 drives the rotating drum 5 to reciprocate on the oil injection assembly through the transmission part, so that a plurality of air jets 7 obliquely arranged on the cleaning cap 6 can act on the oil receiving port area of the sintering machine wheel from far to near. The air jet impulse is continuously strengthened and the air curtain is scanned in a spiral state, which can completely clean the coke attached to the oil receiving port area of the sintering machine wheel. Moreover, since the inner side of the cleaning cap 6 is a concave structure, the rotating cleaning cap 6 can dynamically center the oil receiving port of the sintering machine wheel, avoiding unilateral wear of the oil filling component during a long centering stage and causing leakage.

[0023] In this embodiment, if Figure 2 、 Figure 3 As shown, the oil injection assembly includes: The oil control cylinder 8 and the oil gun rod 9 are arranged on the sliding seat 2 3, and the oil gun rod 9 corresponds to the oil receiving port of the sintering machine wheel; A sealing needle 10 is provided on the output end of the oil control cylinder 8, and the sealing needle 10 cooperates with the port of the oil gun rod 9; The oil inlet 11 is located at the upper end of the oil gun rod 9. During each oil filling process, the output end of the oil control cylinder 8 is retracted, driving the sealing needle 10 to move synchronously to open the oil circuit, and oil is supplied from the oil inlet 11. After the oil filling is completed, the output end of the oil control cylinder 8 is extended, driving the sealing needle 10 to move synchronously to close the oil circuit to prevent the grease in the oil gun rod 9 from leaking.

[0024] In this embodiment, if Figure 2 、 Figure 3 As shown, a spring box 12 is provided on the back of the oil control cylinder 8. The spring box 12 is provided on the sliding seat 2 3. A magnetic induction anti-collision rod 13 is also inserted into the spring box 12. When the oil gun rod 9 is not impacted by external force, the oil gun rod 9 is in a stable position. When the oil gun rod 9 is squeezed or impacted by external force, under the action of the spring box 12, the oil gun rod 9 has a certain buffering toughness and self-resetting ability. Combined with the magnetic induction anti-collision rod 13 inserted in the spring box 12, it can prevent damage to the equipment due to accidental excessive force.

[0025] In this embodiment, if Figure 4 As shown, the transmission unit includes: A rack 14 fixedly mounted on the sliding seat 1 2; The gear 15 provided on the sliding seat 2 3 is rotated by the rotating shaft, and the gear 15 is meshed with the rack 14; A synchronous wheel 16 provided on the other side of the rotating shaft; A second synchronous wheel 17 is provided on the second sliding seat 3, and the second synchronous wheel 17 is connected to the first synchronous wheel 16 via a synchronous belt; Crank rods 18 are respectively provided on the other side of the synchronous wheel 2 17 and on the sliding seat 2 3. Both crank rods 18 are connected to the two sides of the rotating cylinder 5 through rotating beads 19. The rotating cylinder 5 is limited in rotation by a supporting plate 20 and is provided on the sliding seat 1 2. Extension rods are provided on both sides of the rotating cylinder 5, and the ends of the extension rods pass through the rotating beads 19. Specifically, the gear 15 on the sliding seat 23 is driven to move synchronously by the sliding seat 23, and under the action of the rack 14 on the sliding seat 12, the synchronous wheel 16 can be driven to rotate, and then the synchronous wheel 2 17 on the other side is driven to rotate through the tensioned synchronous belt, and further the crank rod 18 corresponding to the synchronous wheel 2 17 is driven to rotate. Since extension rods are provided on both sides of the rotating cylinder 5, and the ends of the extension rods pass through the rotating beads 19, the crank rod 18 corresponding to the other side in the opposite direction can also rotate on the sliding seat 23, and then the rotating cylinder 5 is driven to reciprocate on the oil injection assembly under the limiting action of the support plate 20. This reciprocating action can not only enable the cleaning cap 6 in the rotating state to dynamically align with the oil receiving port of the sintering machine wheel, but also can timely clean the leaking surface of the oil injection assembly itself.

[0026] In this embodiment, if Figure 1 As shown, the driving part includes: A drive motor 21 provided on the mounting frame 1; A lead screw 22 is provided at the output end of the driving motor 21, and the other end of the lead screw 22 is rotatably provided on the mounting frame 1; A connecting block fixedly provided at the lower end of the sliding seat 1 2, the connecting block being threadedly connected to the lead screw 22; Specifically, the output end of the driving motor 21 is driven to rotate forward and reverse to drive the lead screw 22 to rotate alternately in both directions, and the connecting block threadedly connected to the lead screw 22 at the lower end of the sliding seat 2 drives the sliding seat 2 to move back and forth.

[0027] In this embodiment, if Figure 1 As shown, the mounting frame 1 is provided with a bottom guide rail 23, and the bottom guide rail 23 is parallel to the travel direction of the sintering machine trolley wheel. The sliding seat 1 is provided with an upper guide rail 24, and the upper guide rail 24 is perpendicular to the travel direction of the sintering machine trolley wheel. Since the bottom guide rail 23 is parallel to the travel direction of the sintering machine trolley wheel, the moving state of the sliding seat 1 2 can accurately correspond to the travel direction of the sintering machine trolley wheel. Since the upper guide rail 24 is perpendicular to the travel direction of the sintering machine trolley wheel, the moving state of the sliding seat 2 3 can accurately and vertically face the surface of the sintering machine trolley wheel, further ensuring that the oiling end of the oiling assembly accurately docks with the oil receiving port of the sintering machine trolley wheel, thereby minimizing the impact friction between the oiling assembly and the oil receiving port of the sintering machine trolley wheel.

[0028] In this embodiment, if Figure 5 As shown, a cleaning cap 6 is detachably provided at the end of the rotating cylinder 5. The inner side of the cleaning cap 6 is a concave structure, and a spiral oil guide groove 25 is provided inside the cleaning cap 6. The centrifugal force during the rotation of the cleaning cap 6 is utilized to discharge the residues that may be attached to the cleaning cap 6, and the airflow ejected by the air nozzle 7 causes the residues to diffuse and be discharged along the spiral oil guide groove 25, thereby preventing the clean airflow from carrying residual pollutants back into the sintering machine wheel again.

[0029] In this embodiment, if Figure 2 As shown, a positioning sleeve 26 is provided at the end of the oil gun rod 9, and a docking sealing ring 27 is provided on the positioning sleeve 26. The oil gun rod 9 is docked with the oil receiving port of the sintering machine trolley wheel. The docking sealing ring 27 seals the gap between the oil gun rod 9 and the oil receiving port of the sintering machine trolley wheel to ensure that there will be no oil leakage at the docking point. In addition, the positioning sleeve 26 can correct the oil path of the oil gun rod 9 and the oil receiving port of the sintering machine trolley wheel to be in a straight line to ensure that the oil path is normal.

[0030] In this embodiment, if Figure 6 、 Figure 7 As shown, the automatic oiling and lubrication system also includes a closing cover 28 and a closing cover 29 with openings. The closing cover 28 is detachably mounted on the sliding seat 2, and the closing cover 29 is detachably mounted on the sliding seat 3. The oiling end of the oiling assembly extends from the opening to ensure normal oil and gas supply and avoid pollutants in the sintering working environment from being introduced into the automatic oiling and lubrication system, thereby ensuring long-term and stable use.
