AI Technical Summary
Existing underground ventilation pipes cannot effectively serve as escape routes in the event of a mine collapse, and workers' feet or hands may become detached from the spacers while climbing, posing a threat to their lives.
Multiple spacer rings are installed inside the ventilation duct. Each spacer ring is fixedly connected by a connecting rod. A support is rotatably installed on the upper surface of the spacer ring. The support has gaps and is made of high-hardness material with an anti-corrosion coating. Torsion springs are installed between the support for automatic reset.
It provides a safe escape route, reduces the safety threats to workers while climbing, and allows workers to rest on the supports, thus improving escape efficiency.

[0006] Preferably, the support piece is a pair of rotating frames, and the two rotating frames are rotatably installed above the interval ring.
[0007] Preferably, a torsional spring is fixedly installed between each rotating frame and the interval ring.
[0008] Preferably, the ventilation pipe, interval ring and rotating frame are made of high-hardness material, and the outer surfaces of the ventilation pipe, interval ring and rotating frame are provided with a corrosion-resistant coating.
[0009] Beneficial effects
[0010] Compared with the prior art, the utility model provides a ventilation pipe for underground, which has the following beneficial effects:
[0011] The inside of the ventilation pipe is provided with a plurality of interval rings, the plurality of interval rings are distributed at intervals in the length direction of the ventilation pipe, each interval ring is fixedly connected with the ventilation pipe through a plurality of connecting rods, and the upper surfaces of the interval rings with more than one interval ring are rotatably provided with support members, so that even if the feet or hands of the worker are separated from the interval rings, the life of the worker will not be greatly threatened, and the worker can stand on the support members and rest when the worker is tired.
[0012] The above description is only a summary of the technical scheme of the present application, in order to more clearly understand the technical means of the present application, and the content of the specification can be implemented, the following is a preferred embodiment of the present application and the detailed description of the drawings as follows. The specific embodiment of the present application is given in detail by the following examples and their drawings. BRIEF DESCRIPTION OF DRAWINGS

[0018] The following will be combined with the drawings Figure 1 to the drawings Figure 3 The principle and characteristics of the present application are described, and the examples are only used to explain the present application, and are not used to limit the scope of the present application. In the following paragraphs, the present application is described in more detail with reference to the drawings. It should be noted that the drawings are greatly simplified and use non-precise proportions, only to facilitate, clear and assist in the purpose of explaining the embodiment of the present application.
[0019] It should be understood that when an element, referred to as a "fixed" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element, or intervening elements can be present. When an element is referred to as being "disposed" on another element, it can be directly on the other element or there can be intervening elements. The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description only.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.
