Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel dust removal, and particularly relates to a tunnel dust removal trolley. Background Technique

[0002] During the excavation of a tunnel, a large amount of dust will inevitably be generated, seriously affecting the health of tunnel construction workers and management personnel. The occupational hazards caused by dust are manifested as artificial pneumoconiosis. In terms of the current medical level, pneumoconiosis is still an "incurable disease" that can only be prevented but not cured. The key to preventing pneumoconiosis is to do a good job in dust prevention, prevent dust from flying during the production process, minimize the dust concentration, and reduce the influence range of dust. At this time, a tunnel dust removal trolley is needed.

[0003] For example, Patent CN210113381U discloses a tunnel dust removal trolley, which is composed of a track, a moving support, a water collection tank, a water pump, a dust concentration sensor, a column, a long diagonal brace, a short diagonal brace, a water pipe, a shunt pipe, a beam plate, a dust removal fan, an air suction duct, an air outlet duct, a distribution box, a nozzle and a protective cover. The moving support is arranged on the track, the top of the moving support is welded to the column, the water collection tank and the water pump are arranged on one side of the bottom of the column, the dust concentration sensor is placed on the water pump, the long diagonal brace is welded between the column and the beam plate, the short diagonal brace is welded between the welding point of the column and the beam plate and the long diagonal brace, both ends of the water pipe are respectively connected to the water collection tank and the shunt pipe, both ends of the dust removal fan are respectively connected to the air suction duct and the air outlet duct, the distribution box is located on the side of the dust removal fan, the nozzle is connected to the shunt pipe, the nozzle is connected and arranged on the protective cover, and the protective cover is located on the outermost part of the overall structure, ensuring the effect of tunnel dust removal.

[0004] During the use of the above-mentioned tunnel dust removal trolley, the dust removal operation is carried out in advance by the drive of the dust removal fan and the guidance of the air suction and air outlet ducts. However, even if the end of the air outlet duct is connected to the outside of the tunnel to discharge the tunnel, the construction dust discharged will still have a substantial impact on the external environment, and may be re-blown into the tunnel due to the change of wind direction, still causing harm to construction workers.
