Description

Self-resetting structure of cross beam lining plate of cone crusher

Technical Field

The utility model relates to the technical field of crushing equipment, in particular to a self-resetting structure of a cross beam lining plate of a cone crusher.

Background

The main structure of the cone crusher comprises a feed hopper part, an upper frame body part, a movable cone part, a lower frame body part, an eccentric sleeve part, a transmission shaft part, a hydraulic cylinder part, a hydraulic lubrication system, a positive pressure dustproof system and the like.

The feeding port lining plate and the cross beam lining plate which are in contact with the materials and bear the impact and abrasion of the materials at first during the direct production of the conical break belong to the upper frame body part; the time required for the replacement of the liner, and the service life of the liner, are therefore the most important issues. The outside of the lining plate of the feed inlet is attached to the upper frame body, so that the lining plate is not loosened after being lifted in place; the beam lining plate has a gap of more than three centimeters with one side of the beam part of the upper frame body due to casting, and the beam lining plate easily slides along the axial direction of the beam lining plate to drop if being simply hoisted in place, so that the installation mode of the beam lining plate directly influences the functional effect of the later lining plate on bearing material impact and abrasion.

When the beam lining plate is processed in actual production and positioned, a screw is often welded on the beam of the upper frame body, then a hole of the beam lining plate is compared with the screw, the beam lining plate is fixed on the beam by using a nut, as shown in fig. 1, or the beam lining plate is fixed on the beam by using a long bolt, as shown in fig. 2. Such a construction is often only suitable for small material situations, where the free fall energy is insufficient to break the bolt or crack the weld when the material is transported by the transport device to the upper part of the cone crusher. With the development of the crushing industry, the cone crusher is continuously improved, and the feeding amount and the feeding granularity are required to be treated according to the production requirement. When the materials with the diameters of one or two meters enter the crushing equipment, the bolts for fixing the beam lining plates are easily damaged by the large materials, so that the beam lining plate mounting structure is of great importance.

Disclosure of Invention

The embodiment of the utility model provides a self-resetting structure of a cross beam lining plate of a cone crusher, which aims to solve the problems in the background technology.

A self-resetting structure of a cross beam lining plate of a cone crusher comprises an upper frame cross beam, a cross beam lining plate, a spring and a screw rod; the upper frame body cross beam is provided with a first through hole and a second through hole, the cross beam lining plate is provided with a step through hole, the screw rod penetrates through the step through hole, the first through hole and the second through hole, the top of the screw rod is matched with the step through hole for use, and the bottom of the screw rod is fixedly connected with a fixing seat and a locking nut; the outside cover of screw rod establishes the spring, and the crimping of spring top is between first through-hole below and spring fixing base.

Further, the screw is perpendicular to the contact surface of the upper frame body cross beam.

The beneficial effects of the utility model are as follows:

1. according to the utility model, the screw rod and the beam lining plate are tightly pressed on the beam of the upper frame body through the spring, and when the beam lining plate is displaced due to impact of a large block of material on the beam lining plate, the beam lining plate is quickly and automatically reset through the self-restorability of the spring, and the impact on the screw rod can be buffered, so that the impact damage of the large block of material on equipment is reduced to the minimum.

2. According to the movable connecting structure, welding operation is reduced, the nut at the bottom of the screw is disassembled during disassembly, and the situation that the wall thickness of a beam lining plate is thinned and the service life of a large part is influenced due to the fact that welding slag is required to be removed during screw replacement is avoided; the spring, the spring fixing seat and the locking nut are arranged inside the cross beam, so that erosion of sediment and water vapor is avoided, and the problem that the spring is difficult to disassemble after rust is prevented.

3. The beam lining plate in the prior art sometimes has displacement due to loosening of nuts, and the spring provided by the utility model has pretightening force, so that the beam lining plate can be pressed on the beam of the upper frame body at any time, the using effect of the beam lining plate is improved, and the damage of equipment is reduced.
