Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail vehicle screen cleaning machine components, specifically a protective cover for a rail vehicle screen cleaning machine. Background Technology
[0002] The protective cover of the rail vehicle screening machine plays a crucial role in the equipment, providing safety protection. It prevents operators from accidentally coming into contact with high-speed rotating parts such as conveyor belts and excavating chains during the operation of the screening machine, effectively reducing the risk of work-related accidents. It can also block debris such as gravel and mud that are splashed during the screening process, protecting the safety of surrounding personnel and equipment.
[0003] The existing protective covers for rail vehicle screen cleaning machines have the following problems during use: They usually have multiple built-in vertical reinforcing beams for structural reinforcement of the overall rail vehicle screen cleaning machine cover. In order to ensure the ventilation performance inside the cover, they usually do not install reinforcing crossbeams. Therefore, the load-bearing capacity of the rail vehicle screen cleaning machine cover is poor when subjected to lateral loads. At the same time, in order to ensure the normal operating temperature of the equipment, multiple heat dissipation holes are usually opened between the cover and the inner and outer side walls of the cover body for heat dissipation. Although this ensures good ventilation and heat dissipation performance of the cover, the personnel working on the cover are usually located at the front of the cover, that is, on the outside of the cover. The heat inside the cover is dissipated through multiple heat dissipation holes, which can easily cause burns to the personnel on the outside of the cover. Utility Model Content
