Description

Roadway cleaning and vacuuming vehicle

technical field

The invention relates to a cleaning vehicle, in particular to a roadway cleaning and dust suction vehicle, which belongs to the technical field of roadway cleaning.

Background technique

During the excavation process of rock-soil tunnels and coal mine roadways, a large amount of dust will inevitably escape into the airflow as the coal seam or rocks are broken, and the dust that escapes into the airflow will gradually spread to the entire mine along with the ventilation airflow Or in the roadway system of the tunnel, the roadway is gradually covered by deposited dust, and a slight vibration will make the deposited dust diffuse in the ventilation air flow again, affecting the health of underground personnel.

With the continuous development of the economy, underground construction units such as rock-soil tunnels and coal mine roadways pay more and more attention to the environment. After decades of development in our country, the products of road sweeping have been gradually enriched, and road sweeping vehicles can be seen everywhere. But at present, there are relatively few cleaning devices that can clean the side walls of the roadway and can adapt to the working environment of mines or tunnels. Most of them adopt the method of high-pressure water spraying. Although this method is simple and easy to operate, it requires a lot of manpower and water resources, and the sewage formed after washing is difficult to recycle and reuse, resulting in a large waste; if you want to manually clean The entire coal mine roadway has problems such as low cleaning efficiency. Mechanical cleaning methods can improve efficiency. Traditional vacuum vehicles or sweepers have high cleaning efficiency on road surfaces, but most of them are not suitable for cleaning underground roadways. Underground roadway, especially roadway side wall dust cleaning is still a thorny problem.

In order to solve these problems, the Chinese patent No. CN215236491U is a mine side wall pipeline cleaning device that only solves the problem of side wall pipeline cleaning, but it does not solve the cleaning problem of the roadway floor, especially this patent still uses water spray cleaning The cleaning mode makes it produce a large amount of sewage that is difficult to reuse during work, resulting in a large waste.

In order to make the airflow discharged from the dust filter chamber not affect other parts inside the dust collecting and cleaning device 6, so that the discharged wind can be directly discharged from the equipment through the air outlet 69. An exhaust chamber composed of a plurality of dust baffles 65 is fixedly installed between the chambers, and a gap is left on one side of the exhaust chamber to connect with the air outlet 69 .

When in use, a roadway cleaning and vacuuming vehicle is installed, and the fueling equipment can be put into operation.

When the present invention is in use, concrete work is as follows:

When it is necessary to clean a section of roadway, control the mining intrinsically safe driving platform 1 to move the equipment to one end of the roadway, and the driver controls the equipment to start cleaning along the roadway. At this time, the three cleaning parts of itself start to work simultaneously, and the rear cleaning When the dust suction device 5 started to work, the blower fan 62 in the dust collection and cleaning device 6 began to provide negative pressure, and the negative pressure provided by the blower blower 62 made the dust suction port 53 generate suction through the dust suction pipe 63, and the telescopic rod 54 stretched out downwards. Make the cleaning brush 51 contact the base plate, and the cleaning brush 51 starts to rotate to raise the dust on the base plate, and the dust raised is sucked along the dust suction channel formed by the splicing of multiple dust baffle plates 52 at the bottom of the rear cleaning and dust suction device 5 Port 53 is inhaled, and enters dust filter chamber along dust suction pipe 63 and blower fan 62.

When the horizontally installed suction hood main body 2 starts to work, in order to make the dust suction hood main body 2 close to the bottom plate and filter the vibration at the same time to achieve the maximum cleaning effect, the vibration-absorbing rotating shaft I34, the reinforced support frame I35 and the vibration-absorbing rotating shaft The axis II36 connects the main body of the dust collection hood 2 and provides it with a change in the pitch angle, while the support rod I33 provides shock absorption and maintains balance under the action of the shock absorbing spring 32, thereby providing a stable position for the horizontally installed dust collection hood main body 2. Working environment, at this time, since the roller brush main body 23 inside the horizontally installed dust collection hood main body 2 rotates under the drive of the motor 22, the negative pressure provided by the fan 62 is connected to the connecting hose I 213 and the dust suction hard pipe II 214 Pipe I29, at this time, the connecting hose I213 is installed in series on the rear dust suction diversion shell 24 and the front dust suction diversion shell 25 outside the horizontally installed dust suction hood main body 2, the rear dust suction diversion shell 24 and the front dust suction diversion shell The negative pressure provided by the fan 62 can suck the dust raised by the roller brush main body 23 inside the dust suction cover housing 21 into the dust filter chamber, and when the roller brush main body 23 cleans the bottom plate, it is mixed in the roller Dust and rubble in the brush bristles 232 can be sucked in by the roller brush dust suction port 234 first, and enter the dust filter chamber through the dust suction hard pipe I29, the connecting hose I213 and the dust suction hard pipe II214. In use, in order to prevent heavy dust or gravel and other sundries from re-depositing on the bottom plate, the high-pressure air injection device 26 sends the pressurized air flow into the air injection pipe 212 through the connecting pipe 27, and the air injection pipe 212 sends the pressurized air to the air injection pipe 212. The rear air flow is blown into the front chamber inside the dust suction hood housing 21, so that the dust and small pieces of gravel and other sundries in the front chamber are kept raised, and then are sucked by the rear dust suction guide shell 24 or the front dust collector. The guide shell 25 is sucked away.

When the vertically installed dust hood main body 2 starts to work, the position of the dust hood main body 2 is firstly adjusted by the support rod II 43 so that it can be close to the side wall, and the end rotating shaft 46 can adjust the dust hood main body 2 through its own rotation. The pitch angle and forward direction make the main body 2 of the dust collection hood better avoid obstacles such as power distribution cabinets, telephones and roadway entrances. It can cope with the undulating side wall, making it close to the side wall of the roadway, which is convenient for cleaning. The negative pressure provided by the fan 62 is connected to the connecting hose I 213 of the vertically installed dust hood main body 2 through the connecting hose II 215, so that the dust hood Subject 2 is able to do work. The working mode and structure of the dust collecting hood main body 2 installed horizontally and the dust collecting hood main body 2 installed vertically are consistent, which is convenient for later maintenance.

When the dust collection hood main body 2 and the rear cleaning dust suction device 5 clean and collect dust and other sundries through the pipeline and enter the dust collection and ash removal device 6, the fan 62 inside the dust collection and ash removal device 6 will pass through the air outlet pipe 64. The air flow of dust and other debris is blown into the dust filter chamber, and the air flow first impacts on the pre-filter device 66, and is decelerated and blocked step by step by the porous plate I661, the porous plate II662 and the porous plate III663, and the heavier dust and gravel will fall. On the slope 68 , along the slope 68 , it finally falls into the ash hopper 610 , while the lighter dust will be blocked by the filter cartridge 67 , and the airflow filtered by the filter cartridge 67 will finally be discharged from the vehicle through the air outlet 69 .

Through the joint operation of multiple components, this equipment only needs one worker to operate and drive back and forth to clean the floor, sides and even the roof of the roadway as a whole, which can effectively save labor costs and water resources, and effectively ensure that it is used in rock and soil tunnels, coal mine roadways, etc. The environmental sanitation of underground construction sites has significant environmental and economic benefits.
