Description

Technical Field

[0001] The utility model relates to the technical field of mine shaft and tunnel construction, in particular to ventilation equipment for mine shaft and tunnel construction. Background Art

[0002] Mine construction, a key component of the mining industry, involves a complex series of underground excavations, including shafts, tunnels, and chambers, to meet the needs of mining and other underground operations. Simply put, mine construction is the construction of underground spatial structures, including shafts, tunnels, and chambers, designed to meet diverse functional requirements such as mining, transportation, ventilation, and drainage. This engineering field encompasses the entire process, from geological exploration, engineering design, and construction preparation to actual construction and subsequent maintenance. Mine construction is primarily categorized into four main types: mine construction, mine production preparation, mine deepening, and mine auxiliary engineering. Mine construction involves the excavation of a series of shafts, tunnels, and chambers from the surface to the coal seam to enable coal extraction. Mine production preparation focuses on the preparation of tunnels in the mining face and mining area to ensure smooth mining operations. Mine deepening involves the development of new levels and the deepening of the shaft as coal seam mining nears completion to ensure continuous mining operations. Mine auxiliary engineering, including the construction of transportation, drainage, and ventilation systems, provides essential support for mining operations. Mine shaft and tunnel construction is characterized by large engineering workloads, complex construction conditions, high safety risks, and demanding technical requirements. Because construction typically takes place underground, it is constrained by multiple factors, including geological, hydrogeological, and ventilation conditions, significantly increasing the difficulty and complexity of construction. Furthermore, shaft and tunnel construction involves extensive earthwork, support, and lining work, placing significant demands on labor, machinery, equipment, and materials. Furthermore, construction presents safety risks such as collapse, roof falls, and water inrush, necessitating the implementation of stringent safety measures and emergency response plans. The design of mine shaft and tunnel construction is crucial, requiring the economical and rational determination of the cross-sectional shape, dimensions, and support structures of the shaft and tunnel, based on the mine's production needs, service life, and surrounding rock properties. The design process encompasses multiple aspects, including the overall layout of the shaft and tunnel, the design of local tunnels, drilling and blasting design, support design, ventilation design, communication and lighting design, and the design of construction and labor organization. During the construction process, it is necessary to adopt various excavation methods such as jacking, bottom entry, vertical shaft excavation and inclined shaft excavation, and select appropriate support materials and structures according to specific circumstances, such as reinforced concrete support, steel frame support, etc., to ensure the stability and safety of the shafts and tunnels.

[0003] Ventilation equipment plays a crucial role in mine construction. It ensures air circulation within the construction area, removes harmful gases and dust, and provides a safe and healthy working environment for construction workers. Mine construction ventilation equipment primarily includes main fans, local fans, auxiliary ventilation equipment, and related ventilation structures. Together, these devices form a complete ventilation system to meet the ventilation needs of mine construction. The main fan is the core of the ventilation system, providing the primary ventilation power for the entire mine or a specific wing of the mine. Main fans are typically installed on the surface or near the underground parking lot, bringing fresh air into the mine through air shafts and exhausting contaminated air. The selection of main fans requires consideration of factors such as the mine's depth, size, ventilation system layout, and required air volume and pressure. Local fans are used in locations within the mine where throughflow is inadequate or lacks sufficient airflow, such as the tunneling face. They deliver fresh air directly to the working face through ducts, effectively removing harmful gases and dust from the working face. The selection of local ventilation fans needs to be determined based on the specific conditions of the working face, such as excavation length, cross-sectional size, gas outburst volume, etc.

[0004] When conducting ventilation for mine construction and shaft tunnel engineering, it is necessary to ensure the efficiency of ventilation, as well as the stability of the pipeline and the treatment of the exhaust of air in the mine during the ventilation process. However, we take into account that it is not convenient to fix the air duct during the ventilation of traditional mine construction and shaft tunnel engineering, and bolts are needed to fix it, which will greatly reduce the buffering capacity of the pipeline and affect the quality of pipeline use. At the same time, there is a lack of treatment for the extracted mine air, which is extremely inconvenient. Therefore, a mine construction and shaft tunnel engineering ventilation equipment is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a ventilation device for the construction of mine shaft and tunnel projects, which solves the problem that it is inconvenient to fix the air duct during the ventilation of mine shaft and tunnel projects in the prior art, and bolts need to be used to fix it, which greatly reduces the buffering capacity of the pipeline and affects the quality of use of the pipeline. At the same time, there is a lack of treatment for the extracted air in the mine.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

At this time, the hook can swing flexibly, so that the air duct can swing. The air duct has a certain buffering capacity to avoid damage under the action of wind. The fan sucks the air in the mine shaft and tunnel into the frame, and the filter plate filters and absorbs the air to filter the dust therein to avoid clogging of the fan. Compared with the prior art, it is inconvenient to fix the air duct during ventilation of the mine shaft and tunnel project construction, and bolts are required to fix it, which will greatly reduce the buffering capacity of the pipeline and affect the quality of use of the pipeline. At the same time, there is a lack of treatment for the extracted mine air. The method proposed in the utility model can be mounted by the clamp and the hanging ring on the air duct, thereby avoiding the disadvantages of direct fixing with bolts. At the same time, the components in the frame can filter and absorb the dust, avoiding the problem of directly discharging the air in the tunnel to cause pollution, and has high practicality.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5 The air duct 4 is connected to the air filter 11 on one side of the frame 1, and the air filter 3 is connected to the air filter 11 on the other side of the frame 1. The air filter 11 is connected to the air filter 11 on the other side of the frame 1, and the air filter 3 is connected to the air filter 11 on the other side of the frame 1. The air filter 11 is connected to the air filter 11 on the other side of the frame 1. The air filter 11 is connected to the air filter 11 on the other side of the frame 1.

[0024] Furthermore, a push plate 14 is provided on the side of the filter plate 11 away from the air duct 4, and a hydraulic cylinder 15 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and the output shaft of the hydraulic cylinder 15 passes through the side wall of the frame 1 and is fixedly connected to one side of the push plate 14. After the filter plate 11 is pulled out of the frame 1, the hydraulic cylinder 15 is started to push the push plate 14, and the dust inside the frame 1 is pushed out of the frame 1 through the bottom valve 19 by using the push plate 14.

[0025] Furthermore, a sliding block 17 is fixedly connected to one side of the bottom of the push plate 14, and the sliding block 17 is slidably connected to the inner bottom of the frame 1 through a sliding groove 18. The sliding block 17 slides in the sliding groove 18, thereby improving the stability of the push plate 14 during movement.

[0026] Furthermore, the air inlet of the fan 3 is connected to a connecting pipe 10 , and one end of the connecting pipe 10 is connected to one side of the frame 1 , and the inlet of the connecting pipe 10 is located on the side of the filter plate 11 away from the air duct 4 .

[0027] Furthermore, sliders 12 are fixedly connected to both sides of the filter plate 11, and the two sliders 12 are slidably connected to the inner wall of the frame 1 through slide rails 13. The sliders 12 slide in the slide rails 13, thereby improving the stability of the filter plate 11 during the extraction process, and can have a limiting function in the frame 1.

[0028] Furthermore, all adjacent air ducts 4 are fixedly connected by flanges 5, and a limiting threaded rod 9 is provided on the top side of the clamp 16, and the limiting threaded rod 9 is threadedly connected to the two connecting plates 6 in sequence through threaded grooves. The limiting threaded rod 9 can be used to fix the two connecting plates 6, so that the clamp 16 can be tightened.

[0029] In summary:

[0030] First, before installing the air duct, according to the actual layout of the mine shaft and ventilation requirements, the hook position is accurately reserved to ensure that the air duct 4 can cover all areas that need ventilation. The hook is designed to be adjustable so that it can be fine-tuned according to the actual direction of the air duct 4 to achieve the best ventilation effect. The clamp 16 has a certain fastening performance, and the precise adjustment and locking between the two connecting plates 6 are achieved through the limiting threaded rod 9. This design not only simplifies the installation process and improves work efficiency, but also uses the hanging ring 7 to mount the air duct 4. Even when the wind is strong or there is a slight vibration inside the mine, the air duct 4 can absorb energy through the flexible shaking of the hanging ring 7, reduce the impact on itself, thereby extending its service life and protecting the fan 3 from damage. During the process, the fan 3 extracts the air containing dust and other harmful substances inside the tunnel through the air duct 4. In order to effectively filter these harmful substances, the filter plate 11 can capture and adsorb tiny particles in the air, including but not limited to dust, smoke, etc., thereby purifying the air quality and protecting the fan 3 from blockage and wear. At the same time, it also provides a healthier working environment for mine workers. In addition, considering that a large amount of dust may accumulate on the filter plate 11 after long-term operation, the bottom valve 19 can be opened to discharge the accumulated dust, so as to facilitate regular cleaning of the dust accumulated in the frame 1.
