Auxiliary device for replacing gyratory crusher movable cone lining plates

Abstract

The invention discloses an auxiliary device for replacing gyratory crusher movable cone lining plates. The device comprises a base, wherein a barrel is arranged below the base, a lower pressing plateis arranged below the barrel, an inner cavity of the barrel is connected with a guide ring in a sleeve mode, a pressure relieving plate is arranged at the joint of the guide ring and the base, an upper pressing plate is arranged above the guiding ring, the inner cavity of the guide ring is provided with a main shaft, a lower movable cone lining plate is arranged above the base, and an upper movable cone lining plate is arranged above the lower movable cone lining plate. The device has the advantages that the design is scientific and reasonable, the device can withstand multiple impacts of themain shaft and the movable cone lining plates, the main shaft and the movable cone lining plate can fall to the bottom and can be automatically aligned, secondary alignment is not needed, the technical difficulty of maintenance personnel in replacing the movable cone lining plates is simplified, the annual time for traditionally replacing the movable cone lining plates can be greatly saved, and the possibility of rotation of the movable cone lining plates on the main shaft is further reduced.

Description

technical field [0001] The invention is applied in the industrial field, and is specifically an auxiliary device for replacing the cone liner of a gyratory crusher. Background technique [0002] The development of crushing machinery is closely related to the progress of human society and the level of science and technology. With the industry's extreme demand for high-efficiency, high-capacity, high-performance primary crushing operations, gyratory crushers have emerged as the times require. Its daily ore processing capacity is 25,000-40,000 tons, and the weight of a single machine is about 300-500 tons. The output value of the same amount of ferrous metal ore is large. This equipment is widely used in medium and large mines, and the current inventory in China is about 1,000. And the maintenance of this equipment, the process of changing wearing parts is also very complicated, and the workload is heavy. This kind of equipment usually needs to be repaired every month.

Problems solved by technology

And the process of repairing and replacing wearing parts of this equipment is also very complicated, and the workload is heavy.

This kind of equipment usually needs to be repaired every month. Each gyratory crusher needs to replace the common wearing parts 4-5 times a year, and each time it takes 5-8 days to repair. That is to say, each machine is used every year The loss of direct production output value during the maintenance period is 200-800 million yuan

But for the follow-up service of this equipment, such as how to replace the moving cone liner more quickly and scientifically, there is no dedicated process device to realize it.
