High-rise building fires occupy a certain proportion of large and medium-sized cities in fire-fighting and rescue missions around the country. Yunti fire trucks are an indispensable part of this kind of fire. Almost it can be said that Yunti fire trucks are for middle and high-rise buildings. Fire was born. To protect the safety of the trapped people and firefighters within the actual working height of the Yunti Fire Truck, it plays an irreplaceable role. Understanding the role of the Yunti fire truck in firefighting and rescue operations is of great significance in improving the effectiveness of firefighting and rescue missions in mid- and high-rise building fires. The article aims to explore how to maintain and operate the ladder ladder fire truck in order to maximize its effectiveness on the fire.

1 Daily maintenance and maintenance of ladder trucks

Correctly operate, maintain and maintain the ladder truck to ensure that the vehicle is ready for operation and trouble-free operation at any time. It is a prerequisite for the ladder to be effective when it is ensured to “pull, get on, show, and save” on the fire. In routine maintenance, the number of ladder trucks should not be neglected and their maintenance and maintenance should not be neglected. On the contrary, due to the complexity of the structure of the ladder truck and the close connection of various parts and components, the inspection of the vehicle faults will be strengthened, and the number of maintenances will be increased, and a comprehensive inspection of actual combat drills will be conducted every three months.

The elevator ladders of Yunti Fire Truck adopt the method of pulling and lifting by steel wire ropes. Therefore, the steel wire ropes should be inspected and greased frequently to form a layer of oil film on the surface of the steel wire to prevent the wire rope from being etched. For the existing broken yarns, the strands, the wire ropes are disjointed from deformation or corrosion. , Remember to stop using the wire rope must be replaced. The wire rope is run through the pulley at each ladder end of the bottom winch. When the ladder is telescopic, the force of the wire rope varies, and the phenomenon of tripping with the ladder pulley occurs. In general, the operator concentrates his energy on the ladder end during operation. Whether it is close to the predetermined position but ignores this link, when such a phenomenon occurs, not only is the wire rope itself easily damaged, but when trapped or rescue workers pass through the ladder, the ladder will have a downward force and will easily become dangerous. .

2 Operational Precautions for Ladder Fire Truck on Fire Site

2.1 Take measures according to the physical environment of the fire

The ladder fire trucks of the same type of climbing fire trucks on the spot are large-tonnage, ultra-high-grade motor vehicles, and therefore the environment for their use is also very high. After such fire-fighting vehicles enter the site, they should choose a flat and hard ground as far as possible for the needs of rescue and rescue, and avoid the places surrounding the buildings such as septic tanks, water pipes, gas and cables; for the less inclined ground, A solid backing plate is placed under the conflicting legs, so that the vehicle can maintain a stable level as much as possible. When the ladder truck is put into actual use, the horizontal legs should be fully extended as far as possible, and all four legs should support the ground.

2.2 Influence of fire conditions on the operation of Yuntai fire truck

When the instantaneous wind speed exceeds 5 grades, the ladder truck can be put into practical use, but pay attention to the operation under the condition of ensuring safety, pay attention to observe the surrounding conditions and whether the wind power increases, when the instantaneous wind speed exceeds 7 levels, stop using the ladder. Vehicles, where the wind power at a height of 20 meters or more is much larger than the ground. Therefore, under the harsh climate conditions when operating a ladder truck, it must not be forced by experience.

2.3 Operational Considerations During Fire Extinguishing

Only after the firefighters do a good job of personal protective measures can they launch training or firefighting operations on the top platform of the ladder. When firefighters use ladder trucks to carry out high-altitude fire extinguishing training or operations, they should fasten the seat belts in advance and fix the body and platform guardrails securely. When shooting water, they can turn up or down or left and right as required, aiming at the fire source to save fire within an effective distance. The effective distance mentioned here can neither be too close to the fire source, avoid the dispersion of fire points or damage to firefighters and vehicles due to the impact of water flow, nor can it be too far from the fire point, resulting in waste of water and long pump length. The time operation failed and the fighter was delayed. When the ladder cannot rotate at the same time to ensure the stability and safety of the ladder, it is necessary to avoid suddenly starting or suddenly stopping the water spray from the platform inside the platform at the top of the ladder. When the water supply is pressurized or depressurized, it should be carried out slowly to ensure Smooth operation.

3 Set up a database to simulate fire rescue scene and accurately set the ladder fire extinguishing operation plan

In addition to the above basic operational issues, the author believes that the fire department can test the establishment of fire-fighting databases for high-rise buildings and tall flammable facilities within the jurisdiction, and use satellite 3D imaging technology to monitor the database coverage facilities and conduct fire monitoring on the fire accident rescue site. Digital simulation can prevent fires and at the same time, it can ensure that accidents occur at the first time. According to the database data, they can set precise and effective fire extinguishing plans for the ladder trucks.

The contents of the simulation plan should at least include:

(1) According to the satellite imaging accident point and the surrounding environment, simulate the fire-fighting ladder vehicle to reach the accident point's traffic route as soon as possible;

(2) According to the accident report of the building facilities and the height of the fire floor, mathematical modelling is used to determine the height of the ladder that is suitable for dispatch;

(3) Calculate the geometric relationship between the facade of the building and the elevation of the fire truck's climbing operation facade, and provide operating data to the ladder truck driver to ensure that firefighters and fire fighting equipment can reach the ignition point as soon as possible so as to carry out firefighting and rescue operations;

(4) According to the distance of water supply and the time of water supply and the water supply efficiency of Yunti trucks, calculate the sustainable time of fire-fighting and rescue, reasonably allocate resources, and provide scientific and efficient rescue to ensure the safety of firefighters and trapped people.

4 Strengthen the training of firefighters and build a scientific firefighting and rescue force

As one of the special vehicles that are indispensable for fire fighting in high-rise buildings, the Yunti Fire Truck is a comprehensive fire fighting vehicle that combines high rescue, rescue, and fire fighting. It has strong practicality and can only fully recognize its performance. The scientific rescue method can ensure the safety and reliability during its use. Scientific, digital, efficient, accurate fire fighting and rescue requires knowledge-based firefighters to build and use digital information systems. While strengthening the training of full-time personnel in operating ladder ladder fire trucks to enable operators to master their methods of use, performance of various parts, and precautions, it is also necessary to strengthen training in information systems to strengthen the information of firefighters on the fire scene at the frontline. The correct reception and feedback.

To sum up, in the fire fighting of high-rise buildings and flammable facilities and high-altitude rescue operations, multiple factors need to be integrated in order for Yunti fire trucks to exert their maximum effect. While continuing to maintain and maintain the Yunti fire truck, relying on a scientific and digital information system to strengthen the training and management of Yunti fire truck operators, the combination of organic science and technology will enable Yunti fire trucks to maximize their use in firefighting and rescue operations. The role.
