Description

TECHNICAL FIELD

[0001] The present application relates to a special pi-shaped rubber sealing ring for a multi-cylinder hydraulic cone crusher, which can be quickly matched with the inverted pi-shaped groove on the end face of the frame of the multi-cylinder hydraulic cone crusher and can avoid displacement and deformation of the pi-shaped rubber sealing ring. BACKGROUND

[0002] Referring to the drawings Figure 8 and Figure 9 The multi-cylinder hydraulic cone crusher manufactured by the applicant has a diameter of more than 3.2 meters, and the U-shaped rubber sealing ring 01 installed between the frame and the balance ring of the multi-cylinder hydraulic cone crusher has a diameter of nearly 3 meters. The frame has a U-shaped groove with a cross section, the U-shaped rubber sealing ring is embedded in the U-shaped groove, the lower end face of the balance ring has a convex ring in the middle, and the two sides of the convex ring have grooves and form a concave-convex plug-in matching with the upper end face of the U-shaped rubber ring. In the actual use process of the customer, the customer reflects that after a period of use, it is found that it is very difficult to start again after shutdown, the starting power is very large, and the machine cannot be started at all in the later period. In view of this situation, the applicant found through on-site disassembly of the machine that: the U-shaped rubber ring installed between the frame and the balance ring is deformed due to loosening, which directly causes the balance ring to be stuck, resulting in the machine being unable to start. The reason is that the U-shaped rubber sealing ring installed in the groove on the upper end face of the frame is bonded with the groove by using glue. In the actual working condition, since the U-shaped rubber sealing ring is used to seal the lubricating oil in the machine and prevent external dust from entering the machine, the actual situation is equivalent to that the U-shaped rubber sealing ring is immersed in oil. The influence of oil immersion and shaking of the balance ring on the U-shaped rubber sealing ring directly leads to loosening, displacement and deformation of the U-shaped rubber sealing ring, which further causes the balance ring to be stuck, resulting in the machine being unable to start. When replacing the U-shaped rubber sealing ring, not only the heavy balance ring needs to be moved, but also it is very difficult to clean the oil and stains in the groove (U-shaped groove) of the frame, which makes it difficult to clean again. This leads to the U-shaped rubber sealing ring being unable to be bonded firmly with the groove, and the U-shaped rubber sealing ring is often separated from the bonding with the groove, which causes the U-shaped rubber sealing ring to be deformed and dislocated, resulting in the machine being unable to start again after shutdown, and the service life of the rubber sealing ring is greatly reduced. The replacement is time-consuming and labor-intensive, which directly affects the production efficiency of the machine. SUMMARY

[0003] Design purpose: to avoid the shortcomings in the background art, design a special pi-shaped rubber sealing ring for a multi-cylinder hydraulic cone crusher, which can be quickly matched with the inverted pi-shaped groove on the end face of the frame of the multi-cylinder hydraulic cone crusher and can avoid displacement and deformation of the pi-shaped rubber sealing ring.

[0004] Design scheme: in order to realize the above design purpose, the cross section of the rubber sealing ring is designed as an inverted π type structure, which is the main technical feature of the application. The purpose of this design is that the cross section of the rubber sealing ring is inverted π type, and the inverted π type rubber sealing ring structure is composed of a sealing ring support pad, an outer ring-shaped sealing ring and an inner ring-shaped sealing ring standing on the sealing support pad. The outer ring-shaped sealing ring and the inner ring-shaped sealing ring form an integral structure with the sealing ring support pad during manufacturing, and the outer ring-shaped sealing ring and the inner ring-shaped sealing ring standing on the sealing support pad have different diameters, which form a large ring set in a small ring, and a gap is left between the large ring and the small ring. The gap forms a labyrinth structure with the balance ring in the multi-cylinder hydraulic cone crusher, and the outer ring-shaped sealing ring on the sealing ring support pad has an outer ring fixed edge, and the inner ring-shaped sealing ring has an inner ring fixed edge. After the inner and outer ring fixed edges are embedded in the annular groove in the inverted π type groove wall of the end face of the multi-cylinder hydraulic cone crusher, they play a role in preventing and compressing the movement and deformation of the inverted π type rubber sealing ring, thereby solving the problems in the background art.

[0005] Technical scheme: a π type rubber sealing ring special for a multi-cylinder hydraulic cone crusher, the cross section of the rubber sealing ring between the multi-cylinder hydraulic cone crusher and the balance ring is an inverted π type rubber sealing ring.

[0006] Compared with the background art, the application adopts an inverted π type rubber sealing ring between the multi-cylinder hydraulic cone crusher and the balance ring, improves the forming structure of the groove on the end face of the machine base, replaces the U type rubber ring in the background art, solves the problems of looseness, displacement, deformation, balance wheel jamming and the inability to start the whole machine caused by oil immersion and balance ring shaking between the multi-cylinder hydraulic cone crusher and the balance ring, and makes the service life of the inverted π type rubber sealing ring several times longer than that of the prior art, thereby greatly improving the service life of the equipment. When replacing the inverted π type rubber sealing ring, the balance ring does not need to be moved, and the replacement can be quickly completed, which saves labor, time and effort, and is efficient.
