Dismounting and mounting device for moving cone liner plate of HP type cone crusher

Abstract

The invention relates to a dismounting and mounting mechanisms, and particularly relates to a dismounting and mounting device for a moving cone liner plate of an HP type cone crusher. The device is safe to dismount and mount, high in efficiency, and capable of reducing the damage of accessories. The device is characterized in that a rotating base and a speed reduction motor are arranged at the bottom part of a rack; a driving belt wheel is mounted at the bottom part of the rack; a driven belt wheel which is in transmission fitting with the driving belt wheel is arranged on a main shaft; a rotary bracket assembly which is in match with a moving cone is arranged at the upper end of the main shaft; a cutting tool assembly, a driving ratchet wheel assembly and a driven ratchet wheel are mounted at the upper part of the rack; the driven ratchet wheel is connected to the top part of a locking bolt. According to the dismounting and mounting device for the moving cone liner plate of the HP type cone crusher, the rack, the rotating base, the rotary bracket assembly, the speed reduction motor, the cutting tool assembly, the driving ratchet wheel assembly, the driven ratchet wheel and other parts are matched, thus a moving cone assembly can be conveniently supported, and a cutting ring is cut, and as a result, the moving cone liner plate and the moving cone can be separated. The device has the characteristics of being safe to dismount and mount, and high in dismounting and mounting efficiency; in addition, the damage of the accessories can be reduced, and thus the service life is prolonged.

Description

technical field [0001] The invention relates to a disassembly and assembly machine, in particular to a disassembly and assembly device for the movable cone liner of HP cone crushers mainly used in large-scale mines and stone industries. It has the characteristics of safe disassembly and assembly, high efficiency and reduced damage to accessories. Background technique [0002] Nordberg HP series cone crushers are widely used in mining and stone industry. Although this type of equipment has many advantages such as less downtime, low maintenance cost, flexible application, easy operation and convenient maintenance, some conventional methods are still used in the actual process of replacing the moving cone liner, and there are no special automatic tools. For example: 1. To replace the cutting ring, use a torch to cut; 2. Although there is a special wrench for disassembling and assembling the locking bolt, it is still disassembled and tightened by hammering; 3. Replace the moving...

AI Technical Summary

Problems solved by technology

However, in actual operation, the following situations are likely to occur: 1. When gas cutting is used to cut the part close to the resin filler, such as the moving cone liner, the human body will have adverse reactions to the smoke generated by the resin filler at high temperature, although the equipment manufacturer has carried out It is a protection requirement, but in actual work, enterprises often fail to meet the requirements

2. In the process of cutting the cutting ring, due to operational problems, it is easy to damage the locking bolt, and in severe cases, the moving cone will be damaged

3. During the crushing period, it is often difficult to remove the locking bolt due to the expansion of the liner

4. When the gas cutting ring is cut, the locking bolt of the moving cone is caused to expand due to heat. In this case, disassembly is likely to cause interference or transition fit between the thread of the locking bolt and the thread of the moving cone, causing damage to the thread and making it impossible to disassemble. ; Disassembly after complete cooling will affect the normal operation of the subsequent producti
