Description

The utility model relates to mechanical engineering, in particular to fire and emergency rescue equipment, and is designed to extinguish lower and upper forest fires, especially in hard-to-reach areas. It can also be used to extinguish industrial, steppe and peat fires.

A well-known forest fire unit (patent for the invention of the Russian Federation No. 2217197, IPC А62С 3/02, А62С 27/00, 2003), built on the chassis of a military tracked vehicle, on the running device of which a removable rotary platform is installed. Removable modules are mounted on the platform: a cabin for crew accommodation, fire brigade and fire equipment connected to the working equipment of the chassis by means of flexible connecting elements, tanks with fire extinguishing agent.

The disadvantage of this fire-fighting unit is the excess weight arising from the fact that it is made on the basis of the tank, and the need to transport a tank with a fire extinguishing composition and the inability to swim. The unit is able to move only on hard soils, cannot move along swampy terrain and approach a reservoir with grassy banks, the design of the unit does not provide for refueling with water from a reservoir.

Known armored vehicle (Patent for the invention of the Russian Federation No. 2163496, IPC A62C 27/00, 2001), which contains mounted on a caterpillar undercarriage armored casing with a control compartment and a power plant located in its front part and interconnected by means of control drives , personnel compartment, fire fighting equipment and manual fire extinguishers.

However, the well-known armored vehicle has a low carrying capacity - only 2 tons of water and low speed (4-6 km / h) when moving through water barriers, which is not enough for the machine to quickly approach the fire, as well as the impossibility of autonomous use of the fire pump, since it the drive is carried out from the chassis power plant.

The well-known "Caterpillar fire truck" (Patent for a utility model of the Russian Federation No. 111441, IPC А62С 27/00, 2011), adopted as a prototype, made on the basis of an army tracked floating conveyor. The machine contains a chassis, fire equipment, attachments, a cabin equipped with external heat protection, a control system for mounted and fire equipment, a self-irrigation system with water, an air supply system, including additional air cylinders. Fire equipment of the machine includes a fire pump, tanks with extinguishing mixture and compartments with fire-technical weapons. Attachments of the machine include a gun mount, a manipulator, a dozer blade, a plow, a hydraulic pump, a working and pressure hydraulic lines, flow dividers. At the same time, the machine can be made either on the basis of an army self-propelled, GSP ferry, or on the basis of an army amphibious tractor of medium PTS-2, or on the basis of an army amphibious tank PT-76, or on the basis of an army caterpillar floating conveyor PTS-M, or on the basis of Army tracked armored personnel carrier BTR-50. Water propulsion machines can be made in the form of propellers or water jets. Protection of the cabin from heat can be made in the form of asbestos fiber or basalt fiber.

The disadvantages of this caterpillar fire engine, when executed on all types of base chassis, are significant mass and

dimensions, which makes it difficult to move through wooded and swampy areas.

The technical result of the claimed utility model is the creation of a fire engine capable of traveling off-road and overcoming water obstacles afloat, and allowing the use of fire-technical weapons independently and independently of the base chassis, to carry out emergency rescue operations, with the possibility of creating autonomous lighting at the work site.

The technical result is achieved by the fact that a caterpillar fire engine made on the basis of a caterpillar floating conveyor, comprising a chassis, fire equipment, attachments, a cabin, an attachment and fire equipment control system, the fire equipment of the machine including a fire pump, and the attachment of the machine including a bulldozer dump, plow, hydraulic pump, made on the basis of an air transportable snow and swamp vehicle, amphibian, small-sized caterpillar all-terrain vehicle GTMU, and fire equipment The equipment includes a floating motor pump, configured to operate autonomously regardless of the base chassis of the machine, and the attachment of the machine includes halogen floodlights and an electric generator. The caterpillar fire truck is equipped with communications and navigation.

The essence of the utility model is illustrated by drawings. In FIG. 1 shows an internal arrangement of a tracked fire engine. In FIG. 2 shows the appearance of a tracked fire engine.

The caterpillar fire engine is made on the basis of an air transportable snow and swamp vehicle, amphibian, a small-sized caterpillar all-terrain vehicle of the GTMU conveyor (GAZ-73). The GTMU does not have full-time weapons; it is intended for the transport of people, goods, towing trailers, etc. GTMU can be operated on all types of roads and off-road. The all-terrain vehicle is designed for operation and

Garage storage, at ambient temperatures from + 40 ° to -50 °. Inside the closed body of the caterpillar fire engine and the cabin are the seats of 1 commander of the vehicle, a mechanic - the driver and two firemen. Communications and navigation 2 are installed in the cockpit of a multi-purpose mechanized transport device next to the driver's seat 1. Halogen floodlights 3 and gasoline powered tools 4 are located on a shelf 5 mounted in a closed box. Under the shelf 5 are backpack fire extinguishers 6. To provide electricity to the halogen spotlights 3, a portable electric generator 7 with an extension coil, equipped with an internal combustion engine, is located inside the closed body. To ensure water intake from an open source, the machine is equipped with a floating motor pump 8, which is placed during transportation inside a closed body. Also inside the closed box on the right (in the direction of travel) side are two hand-held firefighters shafts 9 and one peat barrel 10. Attached equipment is installed on the machine: a “V” -shaped earthen blade 11, a fire plow 12. Pencil cases for the roof of the body are made fire hoses 13, with a total capacity of 10 fire hoses. On the left and right sides is fixed a trench tool 14.

The proposed multi-purpose transport mechanized device operates as follows. The claimed caterpillar fire truck can move to the place of fire off-road, overcome all types of swamps, overcome water barriers to wade (up to 1.2 m deep) and afloat (more than 1.2 m deep), because GTMU was originally created as a snow and swamp floating vehicle. Also, the claimed tracked fire engine can be delivered to the place of fire by air. For the claimed tracked fire engine, the total weight together with the fire equipment, attachments and combat crew of the fire does not exceed 935 kg, which

confirmed by preliminary calculations and in practice when creating an experimental sample. At the same time, the load capacity of the GTMU, in which the machine retains its off-road characteristics and the ability to swim, is 1000 kg [Track-type small-sized conveyor tractor GT-MU. Manual. - M.: Military Publishing House of the Ministry of Defense of the USSR, 1985. - 511 s]. Thus, the mass of the installed payload does not exceed the maximum permissible carrying capacity of a gas turbine engine; therefore, all off-road properties and the ability to move afloat are preserved. Upon arrival at the place to localize and extinguish the bottom fire, firefighters use backpack fire extinguishers 6, extracting them from under the shelf 5. When organizing the extinguishing of a fire that has spread over significant areas, the fire water is taken from an open natural or artificial water source. For this, the floating pump 8 is removed from the closed body and installed on the water source. Using fire hoses removed from the canisters 13, a hose line is laid. Depending on the task, either a manual fire barrel 9 or a peat barrel 10 is connected to the hose line. On the other hand, the hose line is connected to the floating motor pump 8, which is brought into operation by supplying water to the hose line and further to the trunks for fire extinguishing. At the same time, the motor pump operates autonomously, regardless of the base chassis of the machine. A caterpillar fire engine at this time can carry out other types of work, for example, arranging a mineralized strip around a fire using a fire plow 12 or passages in thickets and debris using a “V” -shaped earth dump 11. In case of emergency rescue operations or if necessary, firefighters can work with gasoline-powered tools 4 or trench tools 14. To illuminate the emergency response area at night

serve as halogen spotlights 3, powered by a portable electric generator 7. A portable electric generator 7, equipped with an extension coil, can also be used to organize temporary power supply of small towns, firefighters camps, headquarters, etc. Since portable electric generator 7 with an extension coil and halogen floodlights 3 can work independently, a fire truck can be used for other works.
