Also called a fixed cone lining plate, a cone breaking lining plate, a cone crusher lining plate, a static cone lining plate, a crushing plate and the like. Because the rolling mortar wall is a consumable of the crusher, the rolling mortar wall needs to be replaced periodically.

As shown in fig. 1, the installation structure of the traditional rolling mortar wall is characterized in that an adjusting sleeve 1a is sleeved on a rolling mortar wall 5a, a matching ring 9a is installed on the upper portion of the adjusting sleeve 1a, and after the upper portion of the rolling mortar wall 5a is tensioned by bolts 8a and wedge blocks 6a, the wedge blocks 6a are supported on the matching ring 9a. It is locked by a lock nut 7 a. Since the contact surface processing accuracy of the rolling mortar wall 5a and the adjustment sleeve 1a is low, the packing 4a is filled between the adjustment sleeve 1a and the rolling mortar wall 5a to increase the contact area thereof. Because of the filler 4a, when the rolling mortar wall 5a is worn and needs to be replaced, the rolling mortar wall 5a needs to be cut by adopting a gas cutting mode, and the replacement is troublesome. When the rolling mortar wall 5a is deformed by a long time of stress, the packing 4a is loosened. The rolling mortar wall 5a is replaced, and when the packing 4a is filled each time, the packing can be used only when the packing completely reacts to meet the strength, and huge manpower, material resources and financial resources are wasted.

Because the traditional rolling mortar wall has the defects of time consumption in installation, troublesome disassembly and influence on working efficiency, a cone crusher adopting a hanging type rolling mortar wall needs to be designed.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 2 to 9, the present utility model provides a technical solution:

a cone crusher adopting a hanging type rolling mortar wall comprises a rolling mortar wall 1 and an adjusting sleeve 9, wherein the rolling mortar wall 1 is in a hollow cone sleeve shape, six groups of lug seats 11 are uniformly distributed at the outer edge of the upper end along the circumferential direction at intervals, and grooves are formed in the outer sides of the lug seats 11. The adjusting sleeve 9 is sleeved outside the rolling mortar wall 1 and is in a hollow cylinder shape, and the lower end of the inner wall surface of the adjusting sleeve is provided with an inner conical surface 92 which is completely matched with the corresponding outer conical surface part of the rolling mortar wall 1 so as to be supported by the rolling mortar wall. An annular sinking groove 91 is formed in the inner wall surface of the adjusting sleeve 9, and the lower end of the matching ring 8 is embedded into the sinking groove 91. The bolt 2 passes through bolt perforation holes on the lug seat 11 and the matching ring 8 along the axial direction to connect and fix the lug seat and the matching ring 8. It is emphasized that in the present embodiment, the bolt 2 is a high strength bolt of 8.8 or more.

The special-shaped backing plate 7 is a rectangular plate with a hole in the center, and the lower end edge of the special-shaped backing plate is provided with an inclined plane, so that the thickness of the special-shaped backing plate 7 gradually increases from the center hole to the edge. The special-shaped backing plate 7 is arranged between the lug seat 11 and the bolt head of the bolt 2, and when the rolling mortar wall 1 is locally extruded to generate axial deformation and axial extension deformation, the special-shaped backing plate 7 with inclination can generate compensation deformation. It is emphasized that: the size of the central hole of the special-shaped base plate 7 corresponds to the size of the bolt 2, so that the inclined surface of the special-shaped base plate 7 can clamp the bolt head of the bolt 2, and when the rolling mortar wall 1 and the adjusting sleeve 9 relatively rotate, the special-shaped base plate 7 and the lug seat 11 of the rolling mortar wall 1 form a group of opposing force to prevent the rolling mortar wall 1 and the adjusting sleeve 9 from relatively rotating.

The second nut 6 is located between the ear mount 11 and the mating ring 8 and serves to secure the bolt 2 to the ear mount 11. The first nut 3 is located above the matching ring 8 and acts to press the matching ring 8 against the adjustment sleeve 9. A nut locking plate 4 and a pressing plate 5 are also arranged between the first nut 3 and the matching ring 8. The nut locking plate 4 is of a rectangular sheet structure with a square hole in the center, and small round holes are symmetrically formed in two sides of the square hole in the center. The pressing plate 5 is of a rectangular sheet structure with a round hole in the center, and small round holes are symmetrically formed in two sides of the round hole. The thickness of the pressing plate 5 is larger than that of the nut locking plate 4, and the pressing plate 5 is matched with the nut locking plate 4, so that the screwing torque of the first nut 3 can be adjusted more easily.

The assembly steps of the utility model are described as follows:

in the first step, the rolled mortar wall 1 is placed on a horizontal plane, the bolts 2 are placed in six connecting grooves on the lug plate 11 through the special-shaped base plate 7, and the second nuts 6 are screwed to fix the bolts 2.

And secondly, hoisting the adjusting sleeve 9 on the rolling mortar wall 1 by using a hoisting tool, so that the contact surface of the rolling mortar wall 1 and the adjusting sleeve 9 is completely contacted.

Third, the matching ring 8 is placed in the correct position. Flatness of the matching ring 8 was measured for one week, keeping the upper surface of the matching ring 8 on the same horizontal plane. The pressing plate 5 is passed through the bolts, and the first nuts 3 are tightened according to the design torque of the bolts 2.

Fourth, according to the position direction of the first nut 3, the nut lock plate 4 is fixed on the matching ring 8 through small round holes on both sides to prevent the first nut 3 from loosening.

When the rolling mortar wall 1 needs to be replaced, a new rolling mortar wall 1 can be replaced by removing the nut locking plate 4, removing the first nut 3 and hanging the adjusting sleeve 1.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
