Description

Technical Field

[0001] The invention relates to a driving ring limiting device of a multi-cylinder cone crusher, belonging to the technical field of crushers. Background Art

[0002] Multi-cylinder cone crusher is an important equipment for crushing stones. It is widely used in metal mines, sand and gravel aggregates, and construction waste recycling. The structure of the existing crushing host is as follows: Figure 1-Figure 4 As shown, it includes a drive ring assembly 1, a mounting seat 3, a reducer 4, a fixed cone assembly 5 and multiple support bearings 7. The drive ring 1-1 in the drive ring assembly 1 is placed on multiple support bearings 7, the support bearings 7 are mounted on the bearing support 6, and the drive ring 1-1 is simultaneously engaged with the pinion 2 of the reducer 4, the fixed cone sliding key 5-1 of the fixed cone assembly 5 is embedded in the guide groove 1-3 of the guide rail seat 1-2, the guide rail seat 1-2 is mounted on the drive ring 1-1, and the guide rail seat 1-2 is installed with a top screw 1-4. When adjusting the discharge port or replacing the liner, the reducer 4 will drive the drive ring 1-1 on the upper part of the crusher, and then drive the fixed cone assembly 5 to move up and down along the guide groove 1-3. When the fixed cone assembly 5 moves upward, due to the force between the guide rail seat 1-2 and the fixed cone sliding key 5-1, the friction force generated will pull the drive ring 1-1 upward, causing the drive ring 1-1 to tilt, and even causing the pinion 2 of the reducer 4 to lose engagement with the drive ring 1-1, making it impossible to realize the rotation function, and damaging the pinion 2 and the drive ring 1-1.

[0003] Currently, when rotating the fixed cone assembly on site, at least two maintenance personnel are required: one to operate the reducer to stop and start, and the other to observe the status of the drive ring on the platform. When the drive ring tilts or the gear at the meshing position is disengaged, the reducer needs to be stopped. The platform personnel use a crowbar to loosen the fixed cone sliding key and the guide groove of the drive ring, correct the drive ring, and restore it to a level state and mesh with the reducer pinion.

[0004] The above method has the following disadvantages:

[0005] a. Crusher is usually located above the platform. When observing and correcting the status of the drive ring, there is a certain risk and the personal safety of the operator cannot be guaranteed.

[0006] b. When the drive ring tilts or the gears at the meshing position disengage, the subsequent operation must be stopped before the rotation is performed, which is not flexible enough.

[0007] c. The drive ring and the drive ring groove are easy to deform, which reduces the service life.

[0008] d. This type of equipment is usually operated in conjunction with jaw crushers, belt conveyors, feeders, etc. If a fault occurs or the liner or internal wear parts need to be replaced, the entire line will be unable to continue working. Summary of the Invention

The sleeve 18-1 is fastened by an end cover 18-6 and a screw 18-5. A through hole for connecting to the cylinder is opened on the fixed shaft 18-3. Figure 7 As shown, a fixed cylinder through hole 10-2 is opened on the cylinder body, and a bearing pin hole 18-7 is correspondingly opened on the fixed shaft 18-3. After the pin passes through the fixed cylinder through hole 10-2 and the bearing pin hole 18-7, the limit bearing 18 is installed in the bearing fixed cylinder 10.

[0071] As an improvement of the embodiment, Figures 8-13 As shown, threaded holes are provided at both ends of the fixed shaft 18-3, which are respectively used to connect the screw 18-5 and the oil cup 18-4. A through hole is provided inside the fixed shaft 18-3 as a lubricating oil channel. The thin shaft section of the fixed shaft 18-3 is provided with the bearing pin shaft hole 18-7, and the thick shaft section of the fixed shaft 18-3 is installed with the sleeve 18-1 and the outer ring 18-2.

[0072] As an improvement of the embodiment, Figure 14 As shown, the bolt head of the retainer fixing bolt 12 can be processed into a smooth surface to prevent the head thread from being damaged when hard contact is made, which affects the use. Of course, the cover plate limiting bolt 8-5 can also adopt this design.

[0073] When used, combine Figure 4 、 Figure 5 and Figure 23 As shown, the limit bearing 18 is pre-installed in the bearing fixing cylinder 10 and tightened, and then the fixing cover plate 8 is installed on the top of the retainer 11. At the same time, the fixing cover plate 8 is connected to the shock-absorbing spring 9 and the bearing fixing cylinder 10 by bolts, so that the limit bearing 18 and the bearing fixing cylinder 10 are located in the U-shaped groove 11-6 on the top of the retainer 11;

[0074] Then the fixing frame 17 is directly welded to the original bearing support 6, or threaded holes are tapped on the original bearing support 6 and fixed with bolts, and the fixed guide rail 13 is installed on the fixing frame 17 by bolts or pins, and the limit frame 16 is pre-installed on the fixed guide rail 13, and then the lower end of the assembled retaining frame 11 is installed in the fixed guide rail 13, and the bottom of the retaining frame 11 is connected to the limit frame 16, and the installation height of the retaining frame 11 on the fixed guide rail 13 is adjusted through the limit frame limit nut 14, the limit frame limit bolt 15, and the limit frame 16, thereby adjusting the height of the limit bearing 18, ensuring that the limit bearing 18 can be effectively installed on the drive ring 1-1 to prevent the drive ring 1-1 from tilting or dislocating.
