Technical Field

[0001] The utility model relates to the technical field of excavation dust removal, in particular to a dust removal negative pressure wind tube rapid leveling self-moving device. Background Art

[0002] At present, tunnel boring machines are widely used in underground mines, which is a concrete manifestation of the mechanized mining of mines. However, the use of tunnel boring machines for tunneling will generate a lot of dust, so a dust removal system is used to solve the dust problem. The most commonly used dust removal methods are dry dust removal and wet dust removal. In view of the particularity of the mirabilite mine, wet dust removal produces a large amount of wastewater, which will affect the normal production of the mine, so dry dust removal is preferred for tunneling dust removal.

[0003] The dry dust removal system consists of a dust removal fan, a dust collector, and a negative pressure air duct (hereinafter referred to as the air duct). Usually, one end of the dust removal air duct is connected to the dust collector, and the other end is placed on the front face of the tunnel boring machine and fixed.

[0004] However, the existing dust removal negative pressure air ducts are generally suspended by slide rails. Due to the influence of the tunnel geological conditions and construction technology, the tunnel roof has ups and downs. Since the chain length is fixed, the slide rail changes with the roof, resulting in uneven suspension and increased suction resistance. Utility Model Content

[0008] Preferably, a hook corresponding to the turnbuckle is fixedly welded to the top of the slide rail.

[0009] Preferably, the multiple sections of the slide rails are connected by spring buckles, and the slide rails are provided with fixing holes corresponding to the spring buckles.

[0010] Preferably, the steel wire rope is fixedly connected to the connecting rod via a U-shaped buckle.

[0011] Preferably, a plurality of fastening holes are provided at both ends of the slide rail.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The ratchet tensioner in the utility model can not only tighten and straighten the hanging wire rope, but also is easy to operate and labor-saving. On the premise of improving the quality of large wire pulling and firm fixation, it further reduces the labor intensity of operators and improves work efficiency; the device has a simple structural principle, greatly improves the extension speed and quality of the wind tube, realizes the rapid leveling and self-movement of the dust removal negative pressure wind tube, and effectively ensures the safety of local ventilation;
