Description

Technical Field

[0001] This utility model patent relates to an automatic oiling device for sintering machine wheels in sintering production in the metallurgical industry, and also relates to a chain wheel oiling device. Background Art

[0002] During the sintering machine's production process, the sintering machine trolley needs to maintain continuous operation. Since the wheels are subjected to harsh working conditions such as high temperature, heavy load, impact vibration, dust erosion and water flushing during operation, the bearing wear is aggravated, and high requirements are placed on grease replenishment.

[0003] In recent years, a number of online automatic refueling devices have emerged that can follow the movement of the wheel and smoothly add lubricant after docking. However, most of them remain in the theoretical research stage. The main reasons are: First, in actual application, because the trolley wheel end cap is a casting, the installation position of the oil cup is inconsistent, and there is an error in the position of the oil cup on the wheel; second, after long-term operation, the trolley wheel rims wear unevenly, and the diameter of old wheels varies greatly; third, the tracking device that follows the trolley wheel has irregular tracking deviations due to long-term operation and signal interference. As a result, the oil cup will deviate from the theoretical wheel center position by about ±8mm, resulting in the refueling gun and the oil cup not being able to dock, or even the refueling gun getting stuck in the oil cup guide device and shearing off in time, which reduces the refueling success rate.

[0040] The sliding sleeve 48 is installed in the sliding bearing 22 of the movable base 2, and the rear end is connected to the driving cylinder 1, and can move forward and backward along the sliding bearing 22 under the action of the driving cylinder 1;

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

[0042] The spring 45 is a compression spring, which is arranged between the rear coupling body 46 and the front coupling body 41;

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

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

[0045] The dustproof bellows 44 is installed on the rear coupling body 46 and the front coupling body 41 and wrapped around the spring 45 .

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

[0047] The refueling gun head 5 comprises a refueling rod 51, a guide head 52, and a refueling nozzle 53. The refueling rod 51 is mounted on the front coupling body 41 of the flexible component 4; the refueling nozzle 53 is fixed to the refueling rod 51 by a threaded connection, and the guide head 52 wraps around the refueling nozzle 53 and is fixed to the refueling rod 51.

[0048] The refueling pipe 3 comprises a rear refueling pipe assembly 31 and a front refueling pipe assembly 32. One end of the rear refueling pipe assembly 31 is connected to the rear end of the pull rod 42 of the flexible component 4, while the other end is secured by a fixing bracket 49 within the inner cavity of a sliding sleeve 48 and connected to the high-pressure oil supply line via a rotary joint 6. The front refueling pipe assembly 32 is mounted on the threaded connection of the refueling hole of the refueling rod 51 of the refueling gun head 5, and the other end is mounted on the front end of the pull rod 42 of the flexible component 4.

[0049] 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.

[0050] The working principle is:

[0051] In the initial state, the drive cylinder 1 is retracted, and the flexible component 4 and the refueling nozzle 5 mounted thereon are at the rearmost end, driven by the drive cylinder 1. The axes of the refueling nozzle 5, the front coupling 41, the rear coupling 46, and the sliding sleeve 48 are aligned. The trolley wheel 73 is mounted with an oil cup 71 and a guide sleeve 72. The oil cup 71 and guide sleeve 72 are concentric, and there is a positional error with the axis of the wheel 73, assumed to be δ1. Due to wear and other factors, the wheel 73 also has a deviation from the theoretical axis, assumed to be δ2. The tracking control error is assumed to be δ3. Therefore, the error δ4 between the centerline of the refueling nozzle 5 and the centerline of the oil cup is within the range of 0 < δ4 < |δ1 + δ2 + δ3|.

[0052] During operation, driven by the drive cylinder 1, the flexible component 4 and the fueling nozzle 5 move forward. When the guide head 52 of the fueling 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, the spring 45 of the flexible component 4 bends and deforms, and the pull rod 42, through the spherical pair formed by the two hemispheres 43-1 and 43-2, tightens the rear coupling 46 and the front coupling 41. The axis of the fueling nozzle 5 and the centerline of the rear coupling 46 and the sliding sleeve 48 are flexibly offset, and the guide head 52 smoothly moves along the guide surface of the guide sleeve 72 until it docks with the oil cup 71. After this, the high-pressure oil supply pipe is activated and oil is delivered.

[0053] After the refueling is completed, the driving cylinder 1 retracts, the flexible component 4 and the refueling gun head 5 retract to the rear end, and the refueling 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, preparing for refueling the next wheel.
