Embodiment 11

[0066] 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 an air spray head 3, a large air volume air outlet 4, and a large air volume suction port 5 in sequence from the front right to the rear, and the dust filter cabin 6, water storage tank 7, and roller brush 2 are sequentially installed on the frame behind the large air volume suction por...

Embodiment 12

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

[0094] 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 retractable hydraulic support rod detects the roller The pressure on the brush 2 will automatically stop applying pressure to the roller brush 2 when the pressure value is greater than 0.1KPa, and the roller brush 2 will automatically rotate to clean the working surface; The bracket drives the jet head 3 to stretch out, and the optical rangefinder installed on the jet head bracket detects the distance between the jet head 3 and the working surface. The head 3 starts to impact the work surface with high-pressure airflow, and at the same time, the air outlet 4 with a ...

Embodiment 31

[0097] Embodiment 3.1: a kind of tunnel dedusting method, it comprises:

[0098] A. The three-dimensional laser detector at the front end of the tunnel dust removal vehicle scans the structure and facilities of the tunnel to be operated in an all-round way;

[0099] B. Transmit the scanned data to the vehicle industrial computer;

[0100] C. The industrial computer controls the extension of the roller brush. At the same time, the pressure sensor installed on the telescopic hydraulic support rod detects the pressure on the roller brush. When the pressure value is greater than 0.1KPa, it automatically stops applying pressure to the roller brush 2. The roller The brush 2 starts to roll backwards to clean the working surface and throw the dust to the rear of the car body;

[0101] D. Air nozzle 3 sprays air to perform secondary dusting on the top and walls of the tunnel;

[0102] E. The large-flow blowing port 4 blows air to spray the dust particles backwards, and at the same ti...

Abstract

A tunnel dust removal vehicle with a drawer-type dust collection cabin and its use method. The shown tunnel dust removal vehicle includes at least two operating vehicles, and the operating vehicles are connected to travel or operate. The first and last two operating vehicles have the same structure, and the front and rear The two operating vehicles are arranged symmetrically with respect to the transverse center line of the operating vehicle. A driver's cab (1) is provided at the front end above the frame of the operating vehicle, and a roller brush (2) is arranged on the frame behind the driver's cab (1). The lower part of the frame behind the roller brush (2) is sequentially equipped with the track bed dirt suction cabin (10), the dirt suction box dirt collection cabin (9) and the spare dirt collection cabin (8) from front to back, and the dirt suction box dirt collection cabin (8). The cabin (9) adopts a drawer-type dust collection cabin with a stacking design. A dust drop opening is set in the dust collection cabin. A pressure sensor is installed under the drawer corresponding to the drop opening. The pressure sensor is electrically connected to the controller. The whole vehicle can meet the requirements of small radius and high-efficiency operation, and fully consider the working field of view to improve the safety of the whole vehicle.

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...
