Description

Technical Field

[0001] The utility model relates to the technical field of stacker-reclaimer parts, and more specifically, to a rotary retainer of a stacker-reclaimer. Background Art

[0002] The function of the stacker-reclaimer slewing bearing is a slewing cage. The axial force, radial force and tipping moment generated by the slewing cage during operation and non-operation keep the machine in a stable state. It is easy to be overloaded during the material reclaiming process, which affects the service life of the device. For this reason, we propose a new type of stacker-reclaimer slewing mechanism to solve the above problems.

[0003] Patent application publication number: CN214166656U A stacker-reclaimer slewing mechanism drives a driven gear to rotate through a beam penetrated by the bottom output end of a servo motor. A disc is rotatably connected to the bottom of the beam. The disc is connected to the beam through a bushing. An annular tooth groove is welded on the edge of the disc, and the annular tooth groove is meshed with the driven gear. The structure is reasonably designed. A pressure sensor is provided between the sling and the hopper to monitor the weight of the material in the hopper to prevent overloading. Remote monitoring is achieved through the cooperation of a communication module and a monitoring terminal.

[0004] However, in actual use, the structure is installed with a driven gear on the rotating body, and the driven gear is meshed with the annular tooth groove on the surface of the disc, so that the entire rotating body rotates relative to the base. In the process of rotation, this structure causes long-term friction between the driven gear and the annular tooth groove, which easily forms a gap with poor stability, and the structure is complex, which is not convenient for later maintenance.
