Description

Technical Field

[0001] The utility model relates to the technical field of thickeners, in particular to a slewing bearing lubrication structure for a hinged rake thickener. Background Art

[0002] Thickeners are core equipment in the solid-liquid separation process. They offer advantages such as simple structure and operation, low energy consumption, and high processing capacity, making them widely used in the mining and metallurgy industries. In hydrometallurgy, thickeners are primarily used for pre-concentrating wet leach material slurries, countercurrent CCD washing of wet leach slurries, concentrating solid products after removing valuable metals from the rich leach solution, concentrating intermediate solid products containing valuable metals from the rich leach solution, and concentrating residual slurries after washing.

[0003] Slewing bearings are essential components of construction machinery. In thickeners, they often serve as the force transmission element between the drive reducer and the center shaft, bearing axial and radial forces, as well as overturning moments. Slewing bearings require lubrication before use. The thickener's operating environment is relatively harsh, with exposure to harsh sunlight, heavy dust, high temperatures, and flying rocks placing very high demands on the slewing bearing's lubrication system. During actual construction, the slewing bearing must be lifted for maintenance to access the rake frame. However, existing slewing bearing lifting methods are cumbersome and unreliable. Furthermore, grease is typically added manually to the raceways in China. Insufficient grease can lead to insufficient lubrication, and when the grease in the raceways needs to be replaced due to aging, the old grease is difficult to drain away. Workers also need to apply grease to the slewing bearing teeth. However, uneven application of grease or the adhesion of hard contaminants to the teeth can easily damage the teeth during meshing.

[0027] Lubricating oil tank 4, provided on support 1;

[0028] A support plate 5 is provided on the lubricating oil tank 4;

[0029] The drive shaft 6 is provided on the lubricating oil tank 4. The support plate 5, the lubricating oil tank 4, and the drive shaft 6 cooperate with each other to form a closed cavity 41 for storing grease. The slewing bearing 2 is provided in the closed cavity 41. The drive element 3 is connected to the drive shaft 6 through the slewing bearing 2 and is used to drive the drive shaft 6 to rotate.

[0030] An oil injection system 7, provided on the support plate 5, for injecting grease into the closed cavity 41;

[0031] The separation device 8 includes a hinge structure, which is respectively connected to the lubricating oil tank 4 and the support 1 for limiting the position when the lubricating oil tank 4 is separated from the support 1. The beneficial effect of the present invention is that the support plate, the lubricating oil tank, and the drive shaft cooperate with each other to form a closed cavity for storing grease, so that the slewing bearing can be lubricated by oil bath, avoiding the need to manually add grease to the slewing bearing raceway, which is time-consuming and labor-intensive, and avoiding the application of grease on the slewing bearing tooth surface, thereby avoiding damage to the tooth surface when the slewing bearing is engaged. The present invention also has the advantages of simple structure, easy assembly, reliable operation, and long service life. The drive gear, slewing bearing, and the interior of the slewing bearing of the hinged rake thickener slewing bearing lubrication structure of the present invention can all be lubricated by oil bath, which can be lubricated in real time during operation, with high work efficiency and simple maintenance. The oil filling system can conveniently discharge waste oil through the oil discharge pipe below the lubricating oil tank, avoiding the situation where the old grease is not completely discharged and contaminates the new grease.

[0032] The separation device 8 includes a separation element 81, which has a first position for installation and a second position for pushing against the lubricating oil tank 4 and / or the support 1 to separate the lubricating oil tank 4 and the support 1. This structure facilitates electrically separating the lubricating oil tank from the support, facilitating operation at the rake frame. Of course, the separation element can also be a pneumatic cylinder, a hydraulic cylinder, or an electric motor. Specifically, there are multiple separation elements 81, which are symmetrically distributed. Each separation element 81 is installed on the lubricating oil tank 4 and pushes against the support 1 to separate the lubricating oil tank 4 from the support 1. This structure ensures uniform force on the lubricating oil tank, making lifting and lowering convenient and reliable.

[0033] The present invention further comprises a limit block 82, which is arranged towards the lubricating oil tank and is used to limit the position of the lubricating oil tank 4 when it falls back.

The oil drain pipe 73 is connected to the lubricating oil tank 4 for draining the grease from the lubricating oil tank 4. This structure solves the problem of smooth discharge of old grease in the raceway when it needs to be replaced due to aging. By lubricating the slewing bearing in an oil bath within the sealed cavity, workers do not need to apply grease to the slewing bearing tooth surfaces, thus avoiding the existing problems of uneven grease application or damage to the tooth surfaces during meshing caused by hard contaminants adhering to the tooth surfaces.

The drive element 3 meshes with the outer ring 22 via the drive gear 31 and is lubricated in an oil bath when the outer ring 22 rotates. This structure makes the slewing bearing lubrication convenient and reliable, facilitates rapid lubrication, and prolongs its service life.

[0037] There are multiple drive elements 3, and the drive gears 31 of the multiple drive elements 3 are all meshed with the outer ring 22 of the slewing bearing 2 and rotate synchronously. The support plate 5 is provided with a bump 51, and the drive elements 3 are mounted on the bump 51 and connected to the support plate 5. This structure facilitates the installation of the drive elements and is simple. The provision of the bump reduces gaps, facilitates installation, simplifies processing, and is easy to assemble.
