An online automatic adjustment mechanism for metallurgical vibration table bearings

Abstract

The present invention discloses an online automatic adjustment mechanism for a metallurgical vibration table bearing, which belongs to the field of equipment management. The mechanism comprises a metallurgical vibration table bearing, wherein the metallurgical vibration table bearing is sleeved with a bearing outer sleeve and a hydraulic torque adjustment component. The metallurgical vibration table bearing is provided with an inner shaft pin, which is sleeved in a bearing connecting plate via the inner shaft pin. The inner shaft pin outer sleeve is provided with an outer bushing accessory, and the outer bushing accessory is provided with a flexible accessory, a wedge-shaped warning inner bushing, and a wedge-shaped warning outer bushing. The present invention solves the problem of the inconvenience of adjusting the existing bushing clearance. The vibration table is monitored by an online vibration monitoring system. If the clearance of the bushing is increased, the oil volume in the hydraulic torque adjustment component is controlled, causing the outer shell of the hydraulic torque component to rotate, driving the wedge-shaped warning inner bushing and the wedge-shaped warning outer bushing to move relative to each other to reduce the clearance of the bushing, thereby completing the adjustment of the bushing clearance; thus, the vibration table can operate at a high performance level, improving product quality and production efficiency.

Description

Technical Field

[0001] The present invention relates to the field of equipment management, and in particular to an online automatic adjustment mechanism for a metallurgical vibration table bearing. Background Art

[0002] The bearings of large metallurgical vibration tables are subject to long-term reciprocating forces, which can cause wear. This wear causes the gap between the bearing shaft and the bearing bush to change. Manual inspection of this gap change is time-consuming and labor-intensive, and it is difficult to detect equipment anomalies in a timely and effective manner.

[0003] A Chinese patent with publication number CN114321183A discloses an intelligent water-lubricated bearing that can automatically monitor the amount of wear. It mainly solves existing drawbacks. The patented resistance measuring device monitors the resistance of the wear layer between two electrodes in real time. As the wear layer is worn, the resistance also changes. By monitoring the resistance change, it is converted into the wear layer change in proportion. Although the above patent solves the problem, in actual operation, if the upper and lower eccentric wear clearances of the metallurgical vibration table bearings are detected, the machine must be stopped and disassembled before the detection operation can be carried out; if the eccentric wear clearance reaches a certain level, the bearing must be replaced, which reduces the practicality of the bearing. Summary of the Invention

[0004] The purpose of the present invention is to provide an online automatic adjustment mechanism for the bearings of a metallurgical vibration table, which has the characteristics of accurate monitoring and timely adjustment. It does not require human intervention or production suspension for maintenance. It can automatically control and adjust the vibration table, so that the equipment can maintain high performance level operation, effectively improve product quality and production efficiency, and solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an online automatic adjustment mechanism for a metallurgical vibration table bearing, comprising a metallurgical vibration table bearing, a bearing sleeve, a bearing connecting plate, a hydraulic torque adjustment assembly, an inner shaft pin, an outer shoe accessory, a flexible accessory, a wedge-shaped warning inner shoe and a wedge-shaped warning outer shoe, the middle part of the outer wall of the metallurgical vibration table bearing is sleeved with the bearing sleeve, the two ends of the bearing sleeve are sleeved with the hydraulic torque adjustment assembly, an inner shaft pin is provided at the center of the metallurgical vibration table bearing, and the metallurgical vibration table bearing is movably sleeved in the middle part of the bearing connecting plate through the inner shaft pin, the outer part of the inner shaft pin is sleeved with the outer shoe accessory, and at least two groups of flexible accessories are symmetrically provided on the outer wall of the outer shoe accessory, a wedge-shaped warning inner shoe is provided between each group of flexible accessories, and a wedge-shaped warning outer shoe is embedded in the outer wall of the wedge-shaped warning inner shoe.

[0006] Preferably, the metallurgical vibration table bearing and the hydraulic torque adjustment assembly are electrically connected to an external vibration online monitoring system respectively.

[0007] Preferably, one end of the bearing sleeve is provided with a sleeve hole, and the bearing sleeve is sleeved with a metallurgical vibration table bearing through the sleeve hole.

[0008] Preferably, a hollow groove is provided at the center of the bearing connecting plate, and through holes are respectively provided at the groove walls on both sides of the hollow groove.

[0009] Preferably, the hydraulic torque adjustment assembly includes a hydraulic torque component housing and an internal hydraulic torque component component, the internal hydraulic torque component component is sleeved inside the hydraulic torque component housing, and the hydraulic torque component housing and the internal hydraulic torque component component are sleeved on both ends of the metallurgical vibration table bearing.

[0010] Preferably, the inner shaft pin is composed of a cylinder and is the inner core of the metallurgical vibration table bearing.

[0011] Preferably, a wedge-shaped groove is provided on the outer wall of the wedge-shaped early warning inner shoe, and the inner diameter of the wedge-shaped groove is matched with the outer diameter of the wedge-shaped early warning outer shoe.

[0012] Preferably, the inner ring of the hydraulic torsion component housing and the outer walls of the wedge-shaped warning inner shoe and the wedge-shaped warning outer shoe are all provided with threads, and the wedge-shaped warning inner shoe and the wedge-shaped warning outer shoe are threadedly sleeved on the inside of the hydraulic torsion component housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention discloses an online automatic adjustment mechanism for a metallurgical vibration table bearing. The mechanism monitors the metallurgical vibration table in real time online through an online vibration monitoring system, and infers the bearing clearance based on the vibration conditions and changes in vibration data. If the vibration conditions indicate that the bearing clearance has increased, the online vibration monitoring system sends an adjustment signal to control the input and output of hydraulic oil in the hydraulic torque adjustment assembly, thereby causing the hydraulic torque component housing to rotate and adjusting the automatic loosening and tightening of the hydraulic torque adjustment assembly. This drives the relative movement of the wedge-shaped warning inner and outer bearings to reduce the bearing clearance, thereby completing the automatic adjustment of the bearing clearance. The flexible fitting is flexible and can be deformed, so the bearing can be reduced. The wedge-shaped warning inner and outer bearings, due to their wedge-shaped characteristics, will inevitably cause radial expansion after axial relative movement. This can reduce the wear of the wedge-shaped warning inner bearing caused by up and down movement, avoiding the disadvantage of frequent bearing replacement. This method does not require human intervention and can automatically control and adjust the vibration table. It does not require production suspension for maintenance, so that the vibration table can maintain high performance and significantly improve product quality and production efficiency.
