Abstract

The utility model discloses an expansion sleeve dismounting device for a jaw crusher, and aims to solve the problems that in the prior art, the dismounting difficulty is higher, the operation of a professional welder needs to be matched, a welded expansion sleeve cannot be repeatedly used, the cost is increased, a hydraulic cylinder cannot be centered, and the working efficiency is high. The position of the hydraulic cylinder is easy to deviate when the hydraulic cylinder is installed, and the pulling-out effect is influenced. The expansion sleeve dismounting device comprises a dismounting ring, a bottom plate and telescopic connecting assemblies which are welded between the dismounting ring and the bottom plate and are annularly distributed at equal intervals. According to the expansion sleeve dismounting device, the dismounting ring and the expansion sleeve are in threaded connection, professional electric welding operation is not needed, the dismounting difficulty is reduced, the expansion sleeve and the dismounting ring can be dismounted, therefore, the expansion sleeve can be repeatedly used, the cost is reduced, the hydraulic cylinder is centered through the self-centering adjusting assembly, it is guaranteed that the acting force effect of the hydraulic cylinder is maximized, and the service life of the hydraulic cylinder is prolonged. And meanwhile, the device can be suitable for hydraulic cylinders of different specifications to support the hydraulic cylinders.
