Description

Technical Field

[0001] This utility model patent relates to an automatic lubrication device for the wheels of sintering machines in the sintering production process of the metallurgical industry, and also to a lubrication device for chain wheels. Background Technology

[0002] During the production process of the sintering machine, the sintering machine trolley needs to maintain continuous operation. Due to the harsh working conditions such as high temperature, heavy load, impact vibration, dust erosion and water spray during the operation of the sintering machine trolley, the bearing wear is accelerated, and the requirements for lubricating grease replenishment are high.

[0003] In recent years, some online automatic refueling devices have emerged, capable of following the movement of wheels and smoothly adding lubricating oil after docking. However, most remain at the theoretical research stage. The main reasons are: First, in practical applications, because the end caps of the trolley wheels are cast iron, the consistency of the oil cup installation position is poor, resulting in errors in the position of the oil cup on the wheel. Second, after long-term operation, the wheel rims of the trolley wheels wear unevenly, and older wheels have significant differences in diameter. Third, the tracking device following the trolley wheels exhibits irregular tracking deviations under long-term operation and signal interference. Therefore, the oil cup may deviate from the theoretically correct wheel center position by approximately ±8mm, leading to problems such as the refueling nozzle failing to dock with the oil cup, or even the nozzle getting stuck at the guide device of the oil cup and failing to disengage in time, resulting in a low refueling success rate.

[0028] The movable base 2 includes a sliding bearing 21, a sliding bearing seat 22, and a bearing stop end cover 23. The sliding bearing seat 2 is installed on the refueling device and can move with the trolley wheel system 7 under the drive of the refueling device following system.

[0029] The drive cylinder 1 is mounted on the movable base 2.

[0030] The flexible component 4 includes a front connector 41, a spring 42, several spherical flexible units 43, a sliding sleeve 44, a pin 45, and a fixed bracket 46.

[0031] The sliding sleeve 44 is installed inside the sliding bearing 22, and its rear end is connected to the piston rod of the drive cylinder 1. It can move back and forth along the sliding bearing 22 under the action of the drive cylinder 1.

[0032] The pin 45 is disposed inside the sliding sleeve 44, and the fixed bracket 46 is disposed at the rear end of the inner cavity of the sliding sleeve 44.

[0033] The spherical flexible unit 43 is disposed between the sliding sleeve 44 and the front connector 41, and respectively cooperates with the front spherical surface of the sliding sleeve 44 and the rear spherical surface of the front connector 41.

[0034] The spring 42 is a tension spring, which has high stiffness when stretched and bent. One end is fixed to the sliding sleeve 44 by a pin 45, and the other end is fixed to the front connector 41.

[0035] The fuel nozzle 5 includes a fueling rod 51, a guide head 52, and a fueling nozzle 53. The fueling rod 51 is mounted on the front connector 41 of the flexible component 4; the fueling nozzle 53 is threadedly fastened to the fueling rod 51, and the guide head 52 is sleeved on the outside of the fueling nozzle 53 and fixedly connected to the fueling rod 51.

[0036] The front end of the refueling pipe assembly 3 is installed at the refueling hole of the refueling rod 51 on the refueling nozzle head 5, and the rear end is fixed on the fixed bracket 45 in the inner cavity of the sliding sleeve 44, and is connected to the high-pressure oil supply line through the rotary joint 6.

[0037] The trolley wheel system 7 includes an oil cup 71, a guide sleeve 72, and a wheel 73. The oil cup 71 and the guide sleeve 72 are concentric.

[0038] The working principle is:

[0039] In the initial state, the drive cylinder 1 retracts, and the flexible component 4 and the refueling nozzle 5 mounted on it are at their rearmost positions under the drive of the drive cylinder 1. The spring 42 is tensioned, and the front connector 41, flexible unit 43, sliding sleeve 44, and refueling nozzle are pulled together by the spring 42, making their axes aligned. An oil cup 71 and guide sleeve 72 are mounted on the trolley wheel 73. The oil cup 71 and guide sleeve 72 are concentric, and there is a positional error between them and the axis of the wheel 73, assumed to be δ1. The wheel 73 also deviates from the theoretical axis due to wear and other reasons, assumed to be δ2. The tracking control error is assumed to be δ3. Therefore, the range of the error δ4 between the centerline of the refueling nozzle 5 and the centerline of the oil cup is: 0 < δ4 < |δ1 + δ2 + δ3|.

[0040] During operation, the fuel nozzle 5 and flexible component 4 move forward under the action of the drive cylinder 1. When the guide head 52 of the fuel nozzle 5 contacts the guide sleeve 72 of the wheel system 7, the guide head 52 slides along the guide surface of the inner wall of the guide sleeve 72. At this time, several flexible units 43 will generate torsional displacement under the drive of the guide head 52, thereby ensuring that the guide head 52 moves smoothly along the guide surface of the guide sleeve 72 until it docks with the oil cup 71. After that, the high-pressure oil supply pipe is activated to start supplying oil.

[0041] After the oiling is completed, the drive cylinder 1 retracts, the flexible component 4 and the oiling nozzle 5 retract to their rearmost ends, and the front connector 41, the flexible unit 43, the sliding sleeve 44 and the oiling nozzle return to the same straight line under the action of the spring 42, in preparation for oiling the next wheel.
