Embodiment 11

[0067] Embodiment 1.1: tunnel dedusting vehicle, such as Figure 1-11 As shown, it includes two operating vehicles, and the two operating vehicles are symmetrically arranged with respect to the transverse center line of the operating vehicle. The front end of the upper frame of the operating vehicle is provided with a driver's cab 1, and the frame behind the driver's cab 1 is provided with rollers. Hairbrush 2, the lower part of the vehicle frame behind the roller brush 2 is sequentially equipped with a ballast bed dirt suction cabin 10, a dirt suction box dirt collection cabin 9 and a spare dirt collection cabin 8, the vehicle frame behind the roller hair brush 2 The upper part is provided with a high-pressure jet head 3, a large-volume air outlet 4, and a large-air volume suction port 5 from front to back, and a dust filter cabin 6 and a water storage tank 7 are sequentially installed on the vehicle frame behind the large-air volume suction port 5. The brush 2 is a retractab...

Embodiment 12

[0093] Embodiment 1.2: Tunnel dedusting vehicle, with embodiment 1.1, difference is: described roller hairbrush horizontal single row 5.

Embodiment 21

[0094] Embodiment 2.1: tunnel dedusting car, with embodiment 1.1, difference is: as Figure 12As shown, the sewage collection cabin 9 of the suction box is a drawer-type integrated warehouse, which adopts a split drawer design and a stacking design. A dust drop opening is set in the dust filter warehouse, and a pressure sensor is installed under the drawer corresponding to the drop opening. When the pressure sensor detects that the pressure value reaches the weight value of a single drawer, the drawer will automatically shift, and the next empty drawer will be replenished to the position where the dust falls. The horizontal and vertical displacement of each drawer is realized by a mechanical chain.

[0095] The working method of the tunnel dedusting vehicle provided by the above-mentioned embodiment is: the tunnel dedusting vehicle is connected and operated to the road section to be operated, firstly the roller brush 2 is stretched out, and the pressure sensor installed at the ...

Abstract

The invention relates to a tunnel dust removal vehicle, which comprises at least two sections of operation vehicles, wherein the operation vehicles run or operate in a coupling mode; the operation vehicles of the head section and the tail section have the same structures, and are in symmetrical arrangement using the transverse center line of the operation vehicles as the symmetry axis; a cab (1) is arranged at the front end of the upper side of a vehicle frame of each operation vehicle; a roller brush (2) is arranged on the vehicle frame behind each cab (1); a track bed sewage suction cabin (10), a sewage suction box sewage collection cabin (9) and a standby sewage collection cabin (8) are sequentially arranged at the lower part of the vehicle frame behind each roller brush (2) from the front part to the back part; a jet head (3), a large-air-volume air outlet (4) and a large-air-volume air sucking opening (5) are sequentially arranged at the upper part of the vehicle frame behind each roller brush (2) from the front part to the back part; and each roller brush (2) uses a plurality of hard hairbrushes arranged in a single row in a transverse direction and arranged in a fan shaped. The tunnel dust removal vehicle is a self-propelled large-scale road maintenance machine integrating the technologies such as a mechanical technology, an electric technology, a hydraulic technology and a pneumatic technology, can perform sweeping and dust removal operation on a tunnel, and does not cause secondary pollution to environment in the tunnel.

Description

technical field [0001] The invention relates to a large-scale dust removal equipment for railways and subway tunnels, and belongs to the technical field of railway machinery design and manufacture. Background technique [0002] Since the cleaning of railway tunnels and subway tunnels is mainly done by artificial high-pressure water guns, the construction is difficult, and a large number of waterproof protection measures are required in the early stage of construction. After construction, a large amount of manpower is still required for post-construction sewage treatment. Therefore, most railway and subway tunnels in China are in use for a long time, and dust removal operations in tunnels are rarely carried out. [0003] Among the tunnel dust removal equipment currently available in the market, there are various types of equipment imported from abroad, and the dust removal technology is mainly air blowing and suction. Due to the widespread use and promotion of fan equipment...
