Description

Multifunctional flat car

Technical Field

The invention relates to the technical field of fire fighting, environmental protection, transportation and construction equipment, in particular to a multifunctional flat car.

Background

The field of fire fighting in factories: the majority of the existing mobile fire extinguishing equipment is dry powder fire extinguishers and small mobile high-pressure water mist. The dry powder fire extinguisher can also have a less slight fire condition, and has no obvious effect on a slightly higher or far away fire condition. Although some units are equipped with small-sized movable high-pressure water mist, the defects are that the water storage amount and the water spraying amount are small, the water storage amount is mostly within 200 liters, the high-pressure water pressure is about 100 kilograms, the water is generally moved by personnel or is independently loaded by a vehicle, the spraying time is within 10 minutes, and when the equipment meets a large and complicated initial fire condition, the fire extinguishing effect is not obvious. Some units are provided with a fire pool and a water storage tank, and the problems of pipeline pressure, water belt length and the like during emergency fire extinguishing are restrictive. In order to further enhance the fire fighting work of the unit, some enterprises purchase one to more small and medium-sized fire trucks, sometimes the water is sprinkled for a few times in a factory, and other times are idle for a long time, so that the large-scale equipment is wasted when being placed. In the peace age, the more dangerous occupations are the fire officers and soldiers. After receiving a fire alarm, the fire officers arrive at the scene at the first time, if traffic jam or complex road conditions are met on the way, the time of arriving at the scene is delayed, at the moment, the best rescue opportunity can be missed on the scene due to equipment problems, the disposal of field personnel and the like, the fire situation is generally difficult to control when fire officers and soldiers arrive, and rescue danger and property loss are increased. If the enterprise unit is provided with the appropriate fire fighting equipment, the field worker is trained to use the equipment, so that the fire condition can be timely controlled or delayed, and the fire officers and soldiers can not be rescued under the dangerous condition when coming. In rainy season, when a cable well, a water pipe valve well or a pit hole drains water, the arrangement of a fire pump, the laying of a water hose and the disposal of a water body are also considered problems. The power generation and illumination parts are mostly independent, and the cable reel is also independently used in cooperation with the generator in a long power supply distance. The equipment has disadvantages in storage, management, transportation, waterproofing, etc.

Construction in the factory, high altitude maintenance and transportation field: the existing equipment integrating equipment cleaning and pipeline dredging is large in size, and particularly pipeline dredging is realized. The device is suitable for water with pressure of more than 200 kilograms and large flow, and enterprises and units of the device are not self-provided and are leased outside. In the aspect of high-altitude construction and maintenance, partial units are provided with a wood ladder, an aluminum ladder or a lifting platform, the wood ladder and the aluminum ladder are generally used at lower parts, certain dangerousness exists during climbing, the lifting platform is large in size, balanced support legs need to be unfolded during working, construction is inconvenient to move, if factory lamp poles are about 6-8 meters in height and are located outside sidewalks on two sides of a road, the ladder or the lifting platform cannot be used during maintenance, and only a crane can be used for matched construction. Some enterprises such as logistics, storage, processing and manufacturing are provided with a plurality of flatbeds for saving transportation time or when the forklift cannot carry goods due to overlarge volume and overlong length, and sometimes the flatbeds are idle for a long time due to inconvenient connection modes of the flatbeds or less transportation work.

The environmental protection field: some units, such as goods yards, construction sites and large warehouses, have large dust in the working environment, and the method of humidifying and dedusting is common, and most common method is water sprinkling or spraying. The water tank truck is generally implemented by small and medium-sized water tank trucks, and because the cost of the water tank truck is not low, the water tank truck is generally available for large enterprises or special municipal sanitation departments, so that not many enterprises with the water tank truck are provided. Some places are not suitable for sprinkling water, such as indoor storage areas where various vehicles go to and from more places, and the vehicles can slip and brake failure can be caused. The construction waste has larger dust in breaking, dismantling, storing and transporting, particularly, the construction waste flies all day by wind and scraping dust when being stored, and the dust is fixed by sprinkling water and is inconvenient, generally a dust screen is covered, but the construction waste is blown away frequently when the wind is strong, and the effect is not good.
