Description

Technical Field

[0001] The utility model belongs to the field of air duct repair tools, and particularly relates to an air duct auxiliary pressurizing and leak repairing device. Background Art

[0002] During the underground production process, the air ducts in the driving roadway are often scratched by sharp tools or torn by forklifts. In order to prevent air leakage from the air duct, air duct glue and patches are used for leak repair. However, this method still results in air leakage again in a very short time. In severe cases, a new air duct has to be replaced again, which not only causes multiple leak repair operations by personnel and wastes labor, but also results in insufficient air volume at the working face in severe cases, posing serious safety hazards. Content of the Utility Model

[0003] The utility model aims to solve the problem that after using air duct glue and patches to repair the air leakage of mine air ducts, the patches are often not evenly pressed and air leakage occurs again.

[0004] The utility model provides the following technical solution: an air duct auxiliary pressurizing and leak repairing device, including a pressurizing airbag, a pressing plate and a binding band; the pressurizing airbag is attached to the patch on the air duct, the pressing plate is pressed on the pressurizing airbag, and the binding band is connected to the pressing plate and surrounds the air duct. The pressurizing airbag pressurizes and tightly presses the patch with the pressing plate as the reaction force support.

[0005] Further, the pressing plate is a rectangular plate, through holes are opened at the four corners of the pressing plate, and two parallel binding bands start from the through holes on one side of the pressing plate, bypass the air duct and are connected to the through holes on the other side of the pressing plate.

[0006] Further, the binding band is a chain.

[0007] Further, the pressing plate includes a leather outer plate and a leather inner lining. Through holes are opened at the four corners of both the leather outer plate and the leather inner lining. The binding band is connected to the through holes of both the leather outer plate and the leather inner lining at the same time. The flexibility of the leather inner lining is greater than that of the leather outer plate.

[0008] Compared with the prior art, the advantages of the utility model are as follows:

[0009] After traditional air duct leak repair, the patches are often not evenly pressed, resulting in air leakage again. After using this air duct auxiliary pressurizing and leak repairing device, the pressure on the air duct patch can be effectively increased, realizing all-round even pressure on the air duct patch. After 24 hours of use, it firmly adheres to the air duct and no longer leaks through the patch. This device is easy to use and made of simple materials. It can not only be recycled, but also be updated at any time according to the air duct diameter or the size of the break. When there is a shortage of on-site materials, other methods can be used instead, truly achieving simplicity, practicality, effectiveness and recyclability. Description of the Drawings

Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0014] like Figure 1 , Figure 2 As shown: an auxiliary pressurized leak-proof device for an air duct, comprising a pressurized airbag 1, a pressure plate 2 and a binding strap 3; the pressurized airbag 1 is fitted with a patch on the air duct 4, the pressure plate 2 is pressed on the pressurized airbag 1, the binding strap 3 connected to the pressure plate 2 embraces the air duct 4, and the pressurized airbag 1 is pressurized to tightly press the patch with the pressure plate 2 as a reaction force support.

[0015] When in use, first tie the pressing plate 2 and the strap 3 to the air cylinder 4, then insert the deflated pressurized airbag 1 between the pressing plate 2 and the patch 5, and finally inflate the pressurized airbag 1 through the inflatable ball provided by the pressurized airbag 1. After the pressurized airbag 1 is inflated, it is supported between the pressing plate 2 and the patch 5.

[0016] Specifically, the pressing plate 2 is a rectangular plate with through holes 2.1 at four corners, and two parallel straps 3 are connected from the through holes 2.1 on one side of the pressing plate 2 around the wind tube 4 to the through holes 2.1 on the other side of the pressing plate 2. The straps 3 are chains, and the chain links can be increased or decreased according to the diameter of the wind tube 4.
