Description

Technical Field

[0001] The utility model relates to the field of cone crusher lining plate assembly, in particular to a hoisting device for installing a cone lining plate of a cone crusher. Background Art

[0002] It is well known that cone crusher is a heavy-duty crushing machinery equipment widely used in mining, metallurgy, construction, chemical and other industries. It has the characteristics of large crushing ratio, high efficiency, low power consumption, uniform product particle size, and is suitable for crushing hard ores. When the cone crusher is working, the motor transmits the rotational torque to the gear through the transmission shaft, and then transmits the driving force to the eccentric sleeve through the gear. The movable cone is driven by the eccentric sleeve to perform a rotary pendulum motion, and the movable cone liner periodically approaches and leaves the fixed cone fixed liner, and the gap between the cone surfaces is used to continuously squeeze the ore and rock in the crushing chamber to achieve material crushing.

[0003] The moving cone liner and the fixed cone liner are installed on the surface of the moving cone and the fixed cone. They are responsible for protecting the crusher body and are the core components of the cone crusher. Their quality directly affects the service life of the crusher. The moving cone liner is a conical liner with a narrow top and a wide bottom. The structure is shown in the attached figure. Figure 1 As shown, during the assembly process, the moving cone liner needs to be installed on the moving cone body. After assembly, there is no gap between the moving cone liner and the contact surface below the moving cone body.

[0004] Since the lining body has no auxiliary lifting structures such as lifting ears and lifting holes, and the characteristics of high manganese steel castings are limited, magnetic lifting devices cannot be used. The current assembly methods of dynamic cone linings are: 1) Welding temporary lifting ears on the lining. Since the lining material is not easy to weld, the welding requirements are high. If the welding is not firm, it is easy to cause safety accidents; after assembly, the welded lifting ears need to be cut off and polished, and the operation time is relatively long; due to the high welding temperature, the local high temperature will cause the internal quality of the lining weld to change, and there will be local cracks, resulting in the risk of product scrapping; 2) Use two cylindrical pins to insert into the two centrally symmetrical light holes on the dynamic cone lining body for lifting. Due to the internal assembly space, the pins cannot be fixed to the lining. Due to the stability of the lifting equipment and other factors, the cylindrical pins are prone to detach from the lining during the lifting process, causing safety accidents and posing great safety hazards; 3) Use wire ropes or slings to bind for lifting. After installation, the wire ropes or slings cannot be extracted from the workpiece body. Utility Model Content
