Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore equipment, in particular to a welding ring for a multi-cylinder cone crusher. Background Technique
[0002] The crushing principle of a multi-cylinder hydraulic cone crusher is as follows: The working components of a multi-cylinder hydraulic cone crusher consist of two frustums, namely a moving cone and a fixed cone. During operation, the motor drives the eccentric sleeve to rotate through a pulley, a transmission shaft, a pinion, and a large gear. The eccentric sleeve drives the moving cone to perform a swinging motion along the inner surface. Where it is close to the fixed cone, the material is crushed by the extrusion and bending of the moving cone. Where it deviates from the fixed cone, the crushed material falls from the bottom of the cone due to gravity. The entire crushing and discharging process is carried out continuously and sequentially along the inner surface. The release oil cylinder part consists of six release oil cylinders 3, three accumulators, and connecting pipelines. The release oil cylinder mainly functions as iron passing protection and cavity cleaning. During normal crushing, it is used to absorb and buffer the impact of the adjustment ring jumping caused by a small number of hard materials.
[0003] The multi-cylinder cone crusher crushes materials through the moving cone liner and the fixed cone liner. The moving cone liner and the fixed cone liner are in direct contact with the materials and wear relatively quickly, requiring periodic replacement. This requires the disassembly and assembly of the liner to be as simple as possible. The moving cone liner is installed inside the moving cone assembly and is locked and fixed with locking bolts and a cutting ring. The moving cone liner is installed on the moving cone.
[0004] The locking bolt is threadedly connected to the moving cone. When the crusher is idling, the rotation direction of the moving cone is the same as the thread helix direction, and the rotation direction of the moving cone is the direction to loosen the locking bolt, which poses a hidden danger of loosening the locking bolt. When the crusher is working, the rotation direction of the moving cone is opposite to the thread helix direction, and the rotation direction of the moving cone is the direction to tighten the locking bolt, which poses a hidden danger of locking the locking bolt. To prevent the locking bolt from loosening and locking, a welding ring is provided between the moving cone liner and the locking bolt, and the locking bolt, the moving cone liner, and the welding ring are welded together. When replacing the moving cone liner, the welding ring is cut open, and a new welding ring is welded during the installation of the moving cone liner.
[0005] At present, the welding rings of multi-cylinder cone crushers are diverse, but they all have the following drawbacks: Since the welding ring has no welding groove, welding can only be carried out on the surface of the welding ring. During the crushing operation of the crusher, the ore in the crushing cavity will wear the weld seam of the welding ring, resulting in the loosening of the moving cone liner and triggering crusher failures. Summary of the Invention
[0006] In view of the deficiencies of the prior art, the utility model provides a welding ring for a multi-cylinder cone crusher, aiming to set a welding groove on the welding ring and perform welding in the welding groove to avoid premature wear of the weld seam by ore.
[0007] To achieve the above object, the present utility model provides the following technical solutions: A welding ring for a multi-cylinder cone crusher, comprising a ring body, a locking bolt, a moving cone liner and a moving cone. The ring body is arranged between the locking bolt and the moving cone liner. The moving cone liner is arranged at the top of the moving cone. The locking bolt fixes the moving cone liner to the moving cone. Welding grooves with staggered distribution are arranged at the connection between the top of the ring body and the locking bolt and at the connection between the bottom of the ring body and the moving cone liner.
[0008] Further, a plurality of first welding grooves are arranged at the top of the ring body, and a plurality of second welding grooves are arranged at the bottom of the ring body.
[0009] Further, the first welding grooves and the second welding grooves are equidistantly distributed.
[0010] Further, the first welding grooves and the second welding grooves are staggered.
[0011] Further, the number of the first welding grooves is the same as that of the second welding grooves.
[0012] Further, the first welding grooves and the second welding grooves have the same shape and size.
[0013] Compared with the existing technology, the present utility model has the following beneficial effects: By arranging welding grooves with staggered distribution on the ring body, the locking bolt and the moving cone liner are connected by welding, and all the welding points are retained in the welding grooves, so that the ore in the crushing cavity during the crushing operation of the crusher will not wear the welding points in the welding grooves in advance, improving the reliability and stability of the crusher.
