The Application of Mining Hand Chain Hoist

The mining hand chain hoist plays an important role in the installation and removal of equipment during the construction of the transverse excavation technology in the fully mechanized coal face.

The mining hand chain hoist plays an important role in the installation and removal of equipment during the construction of the transverse excavation technology in the fully mechanized coal face. According to the author's understanding of Beijing Lieying Hoisting Machinery Equipment Group Co., Ltd., a chain hoist manufacturer in Qingyuan Industrial park, Baoding city, Hebei Province, China,in high gas mines or coal and gas outburst mines, in order to play a significant role in gas control, it is necessary to excavate the connecting horizontal channels between the working face and the roadway before conducting gas control operations. The process flow of Hengchuan excavation is as follows:

After the development machine reaches the opening position of transverse, it gradually turns and straightens. Firstly, manually use lifting tools to lift and remove the reversed loader, which is about 20 meters long, to the side of the tunnel, and then manually dismantle the frame; The second step is to manually use a chain hoist to extend the tail of the belt conveyor to the intersection of Hengchuan Alley, forming a coal transportation system.

As the development machine continues to excavate, it is no longer possible to directly transport the excavated coal to the coal conveyor belt. At this time, it is necessary to manually use lifting tools and chain hoists to transport the 40t scraper conveyor to the installation position of the connecting transverse, complete the installation operation of the 40t scraper conveyor, overlap with the tail of the coal conveyor belt, and form a coal transportation system. Finally, manually use lifting tools and chain hoists to transport the reversed loader to the connecting transverse, complete the installation of the reversed loader, and excavate until the connecting transverse is connected.

After connecting transverse along the channel, normal excavation needs to be resumed. Firstly, it is necessary to manually use lifting tools and chain hoists to dismantle the 40t scraper conveyor and reversed loader, place the equipment on the side of the roadway, clean the retreat of the development machine, and manually retract the tail of the belt conveyor; Secondly, exit the development machine to the normal excavation position; Finally, the installation of the manually towed reversed loader was completed and normal excavation resumed.
