Online tunnel ventilation route adjustment and control system based on automatic adjusting frames

Abstract

The invention discloses an online tunnel ventilation route adjustment and control system based on automatic adjusting frames. The online tunnel ventilation route adjustment and control system comprises the multiple automatic adjusting frames arranged in the longitudinal extending direction of a construction tunnel and an upper computer located in an upper adjustment and control room. The automatic adjusting frames communicate with the upper computer in a wireless communication manner. Each automatic adjusting frame comprises a base fixed to the inner wall of the construction tunnel, an installation support for installation of an adjusted ventilation pipeline, an electric lifting seat for vertically adjusting the installation support in the vertical direction and a horizontal moving mechanism for adjusting the installation support left and right in the horizontal direction. Each base is provided with a parameter input unit used for inputting position information of the corresponding installed installation support. Lifting height detection units are installed on the electric lifting seats. Horizontal displacement detection units are installed on the horizontal moving mechanisms. The online tunnel ventilation route adjustment and control system is simple in circuit, reasonable in design, easy and convenient to operate, good in use effect and capable of easily and conveniently adjusting the ventilation routes of the installed tunnel ventilation pipelines and saving time and labor.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to an online control system for tunnel ventilation paths based on an automatic adjustment frame. Background technique [0002] At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance, and the axial flow fan sends fresh air to the tunnel excavation working face through the ventilation pipe (that is, the flexible air pipe) connected to it. , the dirty air in the cave is expelled out of the cave along the body of the excavated cave under the extrusion of the fresh air sent into the cave. When the tunnel is long, multiple axial flow fans are used in parallel and in series to increase the air volume and air supply distance. But nowadays, most of the above-mentioned fans and ventilation ducts are constructed manually. For lo...

Problems solved by technology

But nowadays, most of the above-mentioned fans and ventilation ducts are constructed manually. For long tunnels, the workload on site is very heavy. It is necessary to move the flexible ducts to be installed first, and then Fixing the moved air duct section by section to multiple air duct fixing parts arranged along the longitudinal extension direction of the tunnel requires a lot of manpower and material resources, which is time-consuming and labor-intensive, which seriously affects the construction efficiency of the tunnel.

Therefore, in the actual construction process, there are many defects and deficiencies in the installation of flexible air ducts for existing tunnel construction, such as large on-site workload, more manpower and material resources required, and low construction efficiency.

At the same time, after the ventilation ducts are laid out, it is inconvenient to move, and it is difficult to flexibly adjust the position of the ventilation ducts according to the actual specific construction needs, so the ventilation effect is not ideal

In summary, there is a lack of an online control system for tunnel ventilation paths based on an automatic adjustment frame with simple circuits, reasonable design, easy operation, and good effects, which can easily adjust the ventilation paths of the installed tunnel ventilation ducts. save time and energy
