Method for assembling lining plates of multi-cylinder cone crusher

Abstract

The invention discloses a method for assembling lining plates of a multi-cylinder cone crusher. Moving cone lining plate installation comprises the steps that parts and tools are prepared; a movable cone lining plate falls onto a movable cone; a cutting ring is placed at the top of the movable cone; a locking bolt penetrates through the cutting ring and is screwed on the movable cone; the movablecone lining plate is centered on the movable cone and is in place; the movable cone lining plate is heated; a locking bolt is tightened; the cutting ring is welded; and epoxy resin is filled. Fixed cone lining plate installation comprises the steps that parts and tools are prepared; a fixed cone is placed on a fixed cone lining plate, so that the fixed cone lining plate and the fixed cone are centered and placed in place; a square head bolt, a spherical nut and a wedge block are installed; the spherical nut is screwed down, so that the wedge block correctly pushes against the fixed cone liningplate; whether the matching surface of the fixed cone lining plate and the fixed cone is tightly attached or not is checked; epoxy resin is filled; and a stop block and a nut lock are arranged to limit the rotation of the square head bolt and the spherical nut. According to the method, the correct, firm and reliable installation of the lining plates can be ensured; and the mounting time of the lining plates of the multi-cylinder cone crusher is saved, so that the replacement efficiency of the lining plates of the crusher is improved.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a method for assembling liners of multi-cylinder cone crushers. Background technique [0002] Multi-cylinder cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. It adopts the principle of "laminated crushing" to improve the yield of primary crushing, simpler and more convenient maintenance and lower operating costs. The moving cone is separated from the main shaft, the main shaft is fixed, and only the moving cone performs swinging motion to improve the structural strength. [0003] The multi-cylinder cone crusher has a movable cone liner and a fixed cone liner to form a crushing chamber. The fixed cone liner is fixed during crushing, and the movable cone liner is driven by an eccentric mechanism to perform a swinging movement along the inner surface of the fixed cone liner. , where the movable cone liner is close to the fixed cone liner...

Problems solved by technology

However, this method has the following disadvantages: 1. There is no special locking bolt pre-tightening tool, which is prone to insufficient locking force of the lining plate, and the phenomenon of loosening and cracking of the lining plate is prone to occur during the production process, resulting in the failure of the equipment to operate. Even damage the copper sleeve of the moving cone; 2. Because there is no clear liner pre-tightening condition, in order to ensure the tightness of the liner, the locking bolt is locked. As a result, the locking bolt cannot be removed when the liner is replaced next time. It is necessary to take a destructive test to dismantle, resulting in the replacement of the locking bolts every time the liner is replaced; 3. There is no requirement for the assembly clearance of the liner, so the clearance of the mating surface of the liner is not checked, and it is impossible to judge the fit and pre-tightening state of the liner ; 4. When it is waste, because there is no fixing method and process and special tools, it takes a lot of preparation time and actual installation and operation time; 5. The safety is poor, the locking of the locking bolt requires a torque of more than 6000Nm, and a sledgehammer is usually required on site The impact will tighten the locking bolt, if there are no protective measures, it will easily trigger a safety accident
