[0001] The present application relates to an automatic oiling device for sintering machine trolley wheels in the sintering production of the metallurgical industry, and also relates to a chain type wheel oiling device. BACKGROUND

[0002] In the production process of a sintering machine, the sintering machine trolley needs to be kept in a continuous working state. Due to the high temperature, heavy load, impact vibration, dust scouring and water flushing and other harsh working conditions that the trolley wheels bear during the operation of the sintering machine trolley, the bearing wear is aggravated, and the requirement for grease supplement is high.

[0003] In recent years, some online automatic oiling devices have appeared, which can follow the movement of the wheels and smoothly add lubricating oil after docking, but most of them are still in the theoretical research stage. The main reasons are as follows: 1. In the actual application process, the end cover of the trolley wheel is a casting, the consistency of the oil cup installation position is poor, and the position of the oil cup on the wheel exists errors; 2. After a long time of operation, the wheel flanges of the trolley wheels are unevenly worn, and there is a large difference in the diameters of the old wheels; 3. The tracking device following the trolley wheels has irregular tracking deviations under long-time operation and signal interference. Therefore, the oil cup deviates from the theoretically significant wheel center position by about ±8mm, resulting in the phenomenon that the oiling gun cannot be docked with the oil cup, and even the oiling gun is stuck in the guiding device of the oil cup and cannot be timely separated and cut off, and the oiling success rate is low.

[0041] The rear connecting cylinder 46 is threadedly fastened to the front end of the sliding sleeve 48, and is connected to the front connecting cylinder 41 through the front hemisphere 43-1, the rear hemisphere 43-2, the spring 45, the pull rod 42 and the locking nut 47;

[0042] The spring 45 is a compression spring and is disposed between the rear connecting cylinder 46 and the front connecting cylinder 41;

[0043] The rear hemisphere 43-2 and the rear connecting cylinder 46, and the front hemisphere 43-1 and the inner spherical surface of the front connecting cylinder form a spherical pair;

[0044] The pull rod 42 passes sequentially through the front hemisphere 43-1, the front connecting cylinder 41, the spring 45, the rear connecting cylinder 46, and the rear hemisphere 43-2, and is fixed by the locking nut 47. The pull rod 42 has an inner hole and threaded connection ports at both ends.

[0045] The dustproof corrugated pipe 44 is installed on the rear connecting cylinder 46 and the front connecting cylinder 41, and is wrapped around the spring 45.

[0046] The fixed bracket 49 is located at the rear end of the inner cavity of the sliding sleeve 48.

[0047] The oiling gun head 5 comprises an oiling rod 51, a guide head 52 and an oiling nozzle 53. The oiling rod 51 is installed on the front connecting cylinder 41 of the flexible component 4; the oiling nozzle 53 is fixed on the oiling rod 51 by screw connection, and the guide head 52 is wrapped around the oiling nozzle 53 and the oiling rod 51.

[0048] The oiling pipe 3 comprises a tail oiling pipe assembly 31 and a front oiling pipe assembly 32. The tail oiling pipe assembly 31 is connected to the rear end of the pull rod 42 of the flexible component 4 at one end, fixed by a fixing support 49 in the inner cavity of the sliding sleeve 48 at the other end, and connected to the high-pressure oil supply pipeline through the rotary joint 6. The front oiling pipe assembly 32 is installed on the oiling hole screw connection port of the oiling rod 51 of the oiling gun head 5, and the other end is installed on the front end of the pull rod 42 of the flexible component 4.

[0049] The trolley wheel system 7 comprises an oil cup 71, a guide sleeve 72 and a wheel 73. The oil cup 71 and the guide sleeve 72 are concentric.

[0050] The working principle is as follows:

[0051] In the initial state, the driving cylinder 1 is retracted, the flexible component 4 and the oiling gun head 5 installed thereon are driven by the driving cylinder 1 to the last end, and the axes of the oiling gun head 5, the front connecting cylinder 41, the rear connecting cylinder 46 and the sliding sleeve 48 are in the same straight line. The oil cup 71 and the guide sleeve 72 are installed on the wheel 73, the oil cup 71 and the guide sleeve 72 are concentric, and there is a positional error δ1 between the oil cup 71 and the guide sleeve 72 and the axis of the wheel 73. The wheel 73 also has a deviation δ2 from the theoretical axis due to wear and other reasons, and the tracking control error is assumed to be δ3. Therefore, the error δ4 between the center line of the oiling device oiling gun head 5 and the center line of the oil cup is in the range of 0<δ4<|δ1+δ2+δ3|.

[0052] In operation, under the action of the driving cylinder 1, the flexible component 4 and the oiling gun head 5 move forward. When the guide head 52 of the oiling gun head 5 contacts the guide sleeve 72 of the wheel system 7, the guide head 52 will slide along the inner wall guide surface of the guide sleeve 72. At this time, the spring 45 of the flexible component 4 is bent and deformed, the pull rod 42 passes through the spherical pair formed by the two hemispheres 43-1 and 43-2, tightens the rear connecting cylinder 46 and the front connecting cylinder 41, the axis of the oiling gun head 5 deviates from the center line of the rear connecting cylinder 46 and the sliding sleeve 48, the guide head 52 smoothly moves along the guide surface of the guide sleeve 72, and finally contacts the oil cup 71. Thereafter, the high-pressure oil supply pipeline starts to supply oil.

[0053] After the oil supply is completed, the driving cylinder 1 is retracted, the flexible component 4 and the oiling gun head 5 are retracted to the last end, and the oiling gun head 5, the front connecting cylinder 41, the rear connecting cylinder 46 and the sliding sleeve 48 are restored to the same straight line under the action of the spring 42, thereby preparing for the next wheel oiling.
