Spherical transitional structure

Abstract

The invention relates to a spherical transitional structure having a simple structure, reliability and practicability and adaptability to a semi-closed and narrow space environment different types of engineering machinery and containing universal joint connections. The spherical transitional structure consists of components such as screws, an oil cylinder, a spherical separation flange, a compression unit, a spherical transitional piece, pins and the like. A semispherical concave surface on one end of the spherical transitional piece is contacted with a spherical surface of an oil cylinder piston rod to ensure the function of a universal joint; a semicircular ring-shaped groove on the middle part of a cylindrical structure on the other end of the spherical transitional piece is matched with the pins inside a lug boss on the bottom part of the compression unit to realize the transitional connection between the oil cylinder and the compression unit. When the piston rod of the oil cylinder stretches out, an acting force outputted by the oil cylinder is transferred to incompact packing materials so as to compact the incompact packing materials through the end surface of the spherical transitional piece which is contacted with the lug boss on the bottom part of the compression unit; and when the piston rod is withdrawn, the retraction of the compression unit can be guaranteed through the ring-shaped groove on the spherical transitional piece and two pins installed inside the lug boss on the bottom part of the compression unit.

Description

technical field [0001] The invention relates to a kind of mechanical connection structure widely used in the occasions where all kinds of personnel are inaccessible, the space size is extremely small and no tools can be used, and the device must have the function of a universal joint. The connection of the components of the solid mechanism, as well as other types of operating machinery for horizontal compaction. Background technique [0002] At present, with the continuous increase of social demand, the problem of energy shortage is gradually emerging, and the development technology of underground resources is also constantly innovating. A new process of horizontal compaction to further increase the mining rate of mineral resources. The compaction equipment is installed at the tail of the hydraulic support and is linked with it to complete the backfilling and compaction of materials in the corresponding space while mining the mineral deposits, ensuring that the surface subs...

AI Technical Summary

Problems solved by technology

In the process of compacting the backfill material, due to the extremely uneven reaction force formed by the material, the free end of the compaction unit (compression sleeve) cannot always keep a straight line motion, and the pressure actuator (oil cylinder) and the compaction unit There must be a spherical joint structure with a universal joint function between them, and the free end of the compaction unit is in the backfill material storage and compression area. During the operation, this area has been closed by the compression equipment, and personnel cannot enter this area to perform maintenance operations.

[0003] Therefore, the daily maintenance operation of the above-mentioned universal joint structure can only be carried out at the rear of the compression equipment, and the structure is located on the bottom plate at the front of the compaction unit. After the compression unit and the oil cylinder are assembled into one body, the operating space provided It is very narrow, how to realize the maintenance of the universal joint structure and the replacement of parts has become a difficult problem
