“This automatic sliding hanging device is really cleverly designed，Realistically solves the problem of difficult dust removal on the excavation working face，Make the air at the work site fresher，Big guy’s vision is clearer。" Li Shipeng, support worker of the comprehensive excavation team of Hanjiawan Coal Company, said excitedly。

Days ago，The automatic sliding hanging device independently designed and processed by the comprehensive excavation team of Hanjiawan Coal Company is officially put into operation，Further improved the working efficiency of the wet dust removal M88 loginfan，Reduced the dust concentration at the work site，Preventing occupational diseases from the source，Protect the health of employees。

Last year，The company successfully applied a complete set of intelligent fast excavation equipment，With the doubled increase in excavation efficiency，Dust control at work sites has become a new contradiction。On the hanging device matching the wet dust removal fan，The flexible dust removal air duct between the anchor digging machine and the anchor transfer machine is affected by the change in separation distance and negative wind pressure，Prone to bending and deformation，Influence dust removal effect，Restricts the smooth operation of safe production to a certain extent。

For this，Comprehensive excavation team mobilizes technology masters and maker power，Carry out research on difficult problems around dust removal。After discussion、Design、Processing、Test、Improvement and other links，Finally innovated the automatic sliding hanging device。

Device by slide rail、Composed of three parts: support frame and hanging ring。The support frames on both sides are respectively m88 casinofixed on the tail of the anchor digging machine and the head of the anchor transfer machine，The slide rail is suspended from the end of the support frame，Connected to the support frame through the limiting device。The hanging rings are evenly distributed，And connect the dust collector and the slide rail together。When the distance between the anchor digger and the bolt loader changes，The hanging ring can slide on the slide rail synchronously，Drive the dust removal fan to achieve horizontal contraction or expansion，Keep the dust collector straight，To achieve the best dust removal effect。

“The air outlet of the dust removal fan is smoother，Better visibility，The safety factor of the working surface has also been improved，Excavation efficiency and project quality are guaranteed，Everyone is more motivated。" said Fang Lei, deputy captain of the comprehensive excavation team。（Guo Siyu）
