Description

Technical Field

[0001] The utility model belongs to the technical field of gas air guide pipes, in particular to a gas air guide pipe used for gas management. Background Art

[0002] The gas air duct used for gas control is the gas extraction pipe, which refers to a facility in coal mines, such as coal mines, that collects, drains and utilizes gas by pre-drilling holes and blasting underground to break the coal wall and then installing a gas extraction pipe. Its main function is to extract the gas underground to the wellhead, reduce the gas concentration in the mine, and prevent gas accumulation from causing explosions or coal dust explosions in the local or entire coal mine. It also has the advantages of energy saving and environmental protection, simple equipment and powerful effects. It is one of the important means to solve the problem of gas hazards in coal mines.

[0003] At present, in the actual application of gas air ducts, it is found that due to the special environment of coal mines, cranes, hoists and other installation tools cannot be used when installing gas air ducts. They can only be carried and installed by manpower, which greatly increases the difficulty of installation work and may cause industrial accidents. Secondly, since fire is strictly prohibited underground, damaged pipes can only be disassembled and transported to a safe area for welding and repair work, which increases maintenance costs;

[0004] In order to solve the above problems, the present application proposes a gas air duct for gas management. Utility Model Content

[0005] The purpose of the utility model is to provide a gas air guide pipe for gas management, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a gas air duct for gas treatment, comprising: an air duct and flange mechanisms at both ends thereof; ring frames are arranged on the outer sides of both ends of the air duct, and arc-shaped baffles are arranged on the outer sides of the ring frames for preventing stones from damaging the surface coating of the air duct, and the arc-shaped structure of the arc-shaped baffles is used to guide stones dropped in the mine cave to the outside; a moving part is also arranged on the outer side of the ring frame for reducing the difficulty of work when transporting the air duct, and a block for switching the use position of the arc-shaped baffle is arranged inside the other side of the ring frame.

[0008] Furthermore, ring seats are provided on the outer sides of both ends of the air guide pipe to limit the ring frame, and a positioning groove for engaging and connecting with a clamping block is provided at the lower end of the ring seat away from the flange.

[0009] Furthermore, a fixing frame for mounting the moving part is provided at the lower end of the ring frame, and a shock absorbing column connected to the moving part is provided at the lower end of the fixing frame.

[0010] Furthermore, a limiting groove for accommodating the card block is provided inside the upper end of the ring frame, and an elastic telescopic rod for automatically ejecting the card block is provided inside the limiting groove.

[0011] Furthermore, buffer columns for buffering falling stones are arranged at equal intervals above the arc-shaped baffle.

[0012] Furthermore, a cross frame for installing a buffer column is arranged on the inner side of the lower end of the fixing frame.

[0013] Furthermore, when the arc-shaped baffle is below the air duct, the clamping block is squeezed by the ring seat and accommodated in the limiting groove.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can be equipped with a ring frame, and when the air duct is transported and disassembled, the arc-shaped baffle plate can be automatically rotated to the bottom position by gravity so that the moving part contacts the ground, so as to facilitate the transportation, installation and maintenance of the air duct. In this process, the arc-shaped baffle plate is used to block the stones thrown up by the road surface to prevent the anti-corrosion coating on the surface of the air duct from being damaged.

[0016] The utility model directly rotates the arc baffle to the upper position after the air duct is installed. At this time, the clamping block is pushed out by the elastic telescopic rod and automatically clamped in the inner part of the positioning groove to form a limit. At this time, the arc baffle can block stones falling from the upper side, so as to prevent the falling stones from hitting the air duct and protect its performance. At the same time, the stones are guided outward to prevent damage to the outer coating of the air duct, thereby extending its service life and ensuring stable performance after long-term use.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
