Project machinery and turntable bearing oil overflow collection device thereof

Abstract

The invention discloses a turntable bearing oil overflow collection device, comprising an oil receiving mechanism, an oil storage container, an oil driving mechanism and an oil conveying passage, wherein the oil receiving mechanism is arranged on the inner side of a web plate of project machinery and further is adjacent to the lower side of a turntable bearing oil overflowing position of the project machinery; the oil storage container is fixedly arranged on the outer side of the web plate; the oil driving mechanism is arranged on the oil receiving mechanism; at least one oil conveying passage is arranged between the oil receiving mechanism and the oil storage container; and the oil driving mechanism is used for driving oil falling to the oil receiving mechanism from a turntable bearing to the oil conveying passage, so as to cause the oil to enter the oil storage container through the oil conveying passage. The invention also discloses the project machinery. In such a way, the project machinery and the turntable bearing oil overflow collection device can prevent the environmental pollution caused by oil leakage.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery and a grease overflow collecting device for a turntable bearing thereof. Background technique [0002] In the prior art, the slewing mechanism is widely used in construction machinery equipment, and the slewing mechanism is composed of a slewing support device and a slewing drive device. [0003] In many cases, slewing bearings are often used as slewing bearings. Due to the heavy load on the slewing bearings, good lubrication is required. Usually, the slewing bearings are lubricated by injecting grease in the way of electric centralized lubrication. However, because the grease cannot be controlled The amount of injection, the slewing bearing is often injected with an excessive amount of grease, and the excess grease is easy to overflow from the slewing bearing.

[0003] In many cases, slewing bearings are often used as slewing bearings. Due to the heavy load on the slewing bearings, good lubrication is required. Usually, the slewing bearings are lubricated by injecting grease in the way of electric centralized lubrication. However, because the grease cannot be controlled The amount of injection, the slewing bearing is often injected with an excessive amount of grease, and the excess grease is easy to overflow from the slewing bearing

[0004] (1) Grease overflows and falls to the ground, which is likely to cause environmental pollution;

[0005] (2) Grease overflows and falls on the aisle ladder, which will easily cause the equipment operator to step on the grease and slip when operating the mechanical equipment, threatening the personal safety of the equipment operator;

[0006] (3) Grease overflowing and falling onto key parts of mechanical equipment such as limit switches and high-strength connection areas are also likely to cause mechanical equipment failure
