Description

A fault detection system for a cone crusher

technical field

The utility model relates to the technical field of mining and aggregate processing equipment, in particular to a fault detection system for a cone crusher.

Background technique

The single-cylinder hydraulic cone crusher can be widely used in various industrial fields such as black, non-ferrous, non-metallic mines and sand and gravel materials. It has large crushing force, high production efficiency, laminated crushing, uniform finished product particle shape, low consumption of consumable parts, and operating cost. The low-level features make the single-cylinder hydraulic cone crusher an indispensable and important role in the crushing industry. The principle is to drive the eccentric assembly to rotate through a pair of meshing gears, and the main shaft assembly is driven by the eccentric assembly. The pendulum motion squeezes and crushes the materials in the crushing chamber. The outer ring of the eccentric assembly is in sliding contact with the bushing of the lower frame, and the inner ring is in sliding contact with the main shaft. Due to the high-speed rotation state of the eccentric assembly and the design of the lubricating oil circuit , the contact position is in oil-immersed lubrication.

The existing fault detection method is to install a temperature sensor in the lubricating oil tank to detect the temperature of the lubricating oil returning to the oil tank, so as to achieve the purpose of detecting the abnormality of the parts, because there is still a long oil circuit between the oil tank and the eccentric assembly. , and the oil return is mainly through its own weight, and the oil return speed is slow. The lubricating oil in the oil tank itself has a temperature, and it takes a certain time to change the temperature of the entire oil tank. This detection method has a relatively large lag and cannot be taken in time. Safeguard
