Description
Technical Field
The utility model relates to a bucket-wheel stacker reclaimer intelligent protection field in the dry coal canopy especially indicates a bucket-wheel machine protection system who is applicable to in the dry coal canopy.
Background
The bucket wheel machine is also called as a bucket wheel stacker-reclaimer, has the functions of stacking and reclaiming, and is large-scale mechanical equipment for continuously loading and unloading bulk materials with high efficiency. The stacker-reclaimer is widely applied to large bulk ports, coal storage yards of thermal power plants, large earthwork construction sites or ore and coal raw material yards of large steel plants, large cement plants and the like; and digging and stacking materials such as coal, sand, stone or coke through a bucket wheel machine. The stacker-reclaimer is evolved from a bucket-wheel excavator, can form a storage yard transportation mechanized system together with a car unloader, a belt conveyor and the like, has high operation efficiency, becomes high-efficiency equipment for continuously loading and unloading bulk materials in modern industry, and is widely applied.
In the process of practical application, the bucket wheel machines are operated by arranging one bucket wheel machine on one track, but sometimes are limited by geographical environment, or in order to reasonably and efficiently realize coal blending, two or more bucket wheel machines are arranged on the same track to operate; and doing so can present the following problems:
during the walking process of the bucket wheel machine, the large arms among the bucket wheel machines can collide; or the big arm can collide with other obstacles; if the vehicle is in work at night, the vehicle body of the bucket wheel machine collides with obstacles or pedestrians under the limitation of illumination and sight;
in the prior art, most bucket wheel machine anti-collision methods need to combine walking data and rotation data of the bucket wheel machine, and the data are obtained through an encoder, but due to the reasons that the distance of a material yard of a stacker-reclaimer is long, a track is uneven, dust is more and the like, once a walking wheel slips, the data of the encoder is inaccurate, and the encoder accumulates errors during long-time operation, so that the data are deviated, and the system is judged incorrectly;
