Description
Technical Field
The utility model relates to the technical field of crushing equipment, in particular to a shaft sleeve structure for conveniently disassembling a movable cone part of a cone crusher.
Background
The main structure of the cone crusher comprises a feed hopper part, an upper frame body part, a movable cone part, a lower frame body part, an eccentric sleeve part, a transmission shaft part, a hydraulic cylinder part, a hydraulic lubrication system, a positive pressure dustproof system and the like.
The connection between the relatively moving parts is mostly soft connection between parts made of structural steel and parts made of copper products, and oil films are added between contact surfaces by a lubricating system to reduce consumption and abrasion among materials during operation.
Only the connection structure between the movable cone part and the upper frame body is special, and a knuckle bearing structure is formed between the movable cone part and the upper frame body, so that two contact parts between the two parts are in hard contact, and in order to realize normal operation of equipment, the cone sleeve at the position of the upper frame body is made of gray iron castings, so that impact load can be absorbed, and the service life is long. The taper sleeve at the movable taper part is made of high-strength steel, so that the hardness is high, and the plastic difference replacement frequency is high.
It is necessary to improve the replacement efficiency in the case where a high replacement frequency is unavoidable.
The shaft sleeve is in large interference fit with the main shaft, and the shaft sleeve is uniformly heated during common installation, so that the shaft sleeve is installed on the main shaft after a certain temperature is reached, and the installation is difficult. The shaft sleeve is more difficult to replace in the field, the shaft sleeve needs to be heated, and the shaft sleeve is pulled out of the main shaft by an external mechanical structure. It is difficult to operate in the field.
Disclosure of Invention
The embodiment of the utility model provides a shaft sleeve structure for conveniently disassembling a movable cone part of a cone crusher, which aims to solve the problems in the background technology.
A shaft sleeve structure for facilitating disassembly of a movable cone part of a cone crusher comprises a circular truncated cone-shaped main shaft, a shaft sleeve matched with the circular truncated cone-shaped main shaft and a gland; the center of the top of the main shaft is provided with a hydraulic oil port, the center line of the main shaft is provided with an oil way in the vertical direction, the main shaft is internally provided with a plurality of radial oil channels in the horizontal direction, and the oil channels extend to the side wall of the main shaft; the top of the main shaft is fixedly connected with a gland.
Further, the oil duct comprises a first layer of oil duct and a second layer of oil duct, and the first layer of oil duct and the second layer of oil duct are both positioned at the middle upper part of the main shaft.
Further, the gland is connected with the main shaft through a fixing screw.
The beneficial effects of the utility model are as follows:
according to the utility model, hydraulic oil is injected into the hydraulic oil port through external hydraulic equipment, the hydraulic oil acts on the shaft sleeve through the oil way and the oil way, the shaft sleeve is supported to be large and then exits from the contact area with the main shaft, and the shaft sleeve is disassembled. According to the scheme, flame cutting required by dismounting the shaft sleeve is reduced, induction heating equipment and the like are reduced, and the danger of on-site ignition and electrokinetic is reduced. The shaft sleeve can be easily detached and replaced by the pressure of the matched hydraulic oil station, so that the replacement time is shortened, and the risk of operation in an operation area is avoided.
Compared with the prior art, the hydraulic system is used for operation, so that the manpower consumption is reduced, the on-site fire hazard is reduced, the safety of on-site personnel is ensured, the equipment is intact, the time and money waste for disassembling the shaft sleeve are saved, the hydraulic system and the necessary hydraulic operation during the equipment production are effectively combined, and the equipment increase is reduced.
