Description

The utility model relates to special-purpose vehicles designed for towing aircraft (aircraft) using a carrier (airfield vehicle, tractor), extinguishing fires on aircraft and runways, for anti-icing processing of aircraft or for cleaning (washing) of the flight surface fields.

A fire-fighting aerodrome vehicle is known from the prior art, comprising a three-axle car chassis with a subframe, on which a fire module consisting of a heat-insulated water tank with an integrated foam tank, front and rear compartments with curtain doors, and a pump unit installed in the rear compartment is fixed by means of elastic supports . In addition, it contains a fire extinguishing installation on airplanes with an independent hydraulic drive and an easily removable runway foam covering unit, consisting of two parts made in the form of pipelines with nozzles connected to the pump unit and foam generators, mounted on the front and rear bumpers, respectively, mounted on the roof of the front compartment is a montage installation with a platform for the monitor, in addition, the bottom of the tank in cross section is convex in an arcuate shape (RU 39496, 08/10/2004). This source is selected as a prototype.

This tool has a narrow functionality - fire extinguishing, which does not allow using it as a tractor, for expensive cleaning, anti-icing handling, etc.

The problem to which the proposed utility model is directed is to create a special means of transport — a universal airfield, which would eliminate the above disadvantages.

The technical result achieved by the implementation of this utility model is as follows:

1. Use as ballast, providing the necessary adhesion of the wheels to the airfield, instead of useless metal or concrete cargo - “useful” water or anti-icing liquid, as well as the mass of additional equipment.

2. Use as seasonal equipment (deiser, sweeper), as well as rarely used and expensive equipment (fire truck) in constant mode - in operations that form the user's revenue side.

3. Using the traction force generated by the heavy tractor for other operations (snow removal with a dump) as a pushing force.

4. Expansion of functionality due to the rational use of the same machine units for different functions (pump for liquids, pump for air, boom, etc.).

5. The use of combinations of various equipment, in particular the use of a brush to clean the airfield during towing, allows you to increase the coefficient of adhesion during rainfall.

6. The use of a boom arm for de-icing aircraft in deicer mode and for supplying OTC without the help of firefighters (only by controlling one driver) to hard-to-reach places in case of aircraft fire, including inside highly located engines or inside the aircraft cabin.

7. The use of 1 unit of equipment and 1 person (driver) to perform several sequential operations during aircraft maintenance (towing and de-icing, fire fighting and towing of an emergency aircraft, etc.). Operating costs, time, maintenance costs are reduced.

8. The use of 1 unit of equipment in constant load mode, both during flights during aircraft maintenance (tractor, deiser, fire engine), and in the absence of flights (sweeper).

9. Reducing the response time to fires that occur during aircraft maintenance, or in the immediate vicinity of the service area (parking, taxiways), the use of a tractor for fire-fighting patrolling of the airfield. The SST-AU is often located in the immediate vicinity of the aircraft and is ready for operation (started, warmed up, etc.), while the fire engine takes time to arrive from the emergency rescue station or fire station.

The specified technical result is achieved in a transport vehicle — aerodrome universal, comprising a body with a cabin, in which there is a motor connected to at least one hydraulic pump, at least one tank with water, at least one tank with anti-icing liquid, a tank with a foaming agent, connected to the gun barrel, hydraulic pump for supplying anti-icing fluid, boom for anti-icing treatment, air compressor with hydraulic actuator, fire pump with hydraulic actuator and water open communications for the supply of extinguishing agents, and including a tank heating system, a hydraulic system, an electrical system, a video surveillance system, an electronic control system, trailed devices, one of which

 located on the cab, and the other on the rear of the body, and attachment equipment mounted on the front of the cab.

The electrical system is connected through a generator to the engine.

The anti-icing boom is extendable, contains nozzles and is a multi-link manipulator, the links of which are driven by hydraulic cylinders and hydraulic motors.

The gun barrel is telescopic and mounted on a body near the cab.

The essence of the utility model is illustrated by drawings, where in Fig.1 shows a side view of the SST-AU; figure 2 is a top view of the CCT-AU; figure 3 is a front view of the CST-AU.

ССТ-АУ consists of the main parts: body, engine, hydraulic pump (one or several), hydrostatic transmission, consisting of hydraulic motors that rotate each wheel, tow hitch, water tanks, tank (one or several) with anti-icing fluid, tank from

foaming agent, tank heating system, hydraulic pump for supplying anti-icing fluid, boom for anti-icing treatment, hydraulic fire pump and water lines for supplying fire extinguishing compounds, fire monitor for supplying fire extinguishing composition, hitch for cleaning equipment, air compressor, with hydraulic motor, hydraulic a system consisting of hoses and valves to ensure the supply of hydraulic fluid to the hydraulic motors, an electrical system to control all SST-AU systems.

Ensuring the necessary adhesion of the wheels of the SST-AU with the surface of the airfield is achieved by increasing the total weight of the SST-AU due to the use of water as ballast, which is poured into the tanks / containers located inside the tractor body. SST-AU is equipped with special equipment that allows it to be used as an airfield fire truck, aircraft anti-icing machine, or airfield surface cleaning (washing) machine, using ballast water and a powerful hydraulic system.

The SST-AU body is a supporting structure that accepts all loads and serves as a platform for attaching all other equipment and components. The body consists of a supporting body, a driver's cab, removable panels and technological hatches.

The engine (diesel) is attached to the body through vibration dampers. The engine is used to drive the hydraulic pump (hydraulic pumps), creating pressure in the hydraulic system and drive the generator to power the electrical system SST-AU.

A hydraulic pump (one or more) of high power is attached directly to the engine and creates pressure in the hydraulic system, with the help of which all actuators SST-AU are driven.

The movement of the SST-AU is provided by 4 or more drive and steered wheels. The transmission is hydrostatic, the wheels are driven by hydraulic motor wheels. The steering system allows for different control options: only the front wheels, all wheels, the movement "crab move", etc. The range of characteristics of the motor wheels allows you to develop maximum traction when moving and at speeds up to 30 km / h forward and backward, simultaneously, saved

the ability to move SST-AU forward with a maximum gross weight at speeds up to 120 km / h.

The multi-level hitch is used to dock tow carriers used when towing aircraft. The towing device is located on the front and rear of the SST-AU for towing forward and reverse.

There are water tanks inside the body, which in the tractor mode ССТ-АУ is ballast, in the fire engine mode it mixes with the blowing agent and is a fire extinguishing agent (OTC), in the deicer mode it mixes with type I liquid and is used for de-icing the aircraft, in the cleaning mode SST-AU machines are used to clean the airfield with a water jet.

A tank (or tanks) with anti-icing fluid are located inside the body. The total volume of the tanks is approximately equal to the volume of the water tanks to ensure mixing in the required range of proportions. In the spring-summer period, when anti-icing processing of aircraft is not carried out, these tanks SST-AU can be filled with water to increase the ballast or stock of OTS.

A tank with a foaming agent is used for liquids (foaming agents) that increase the fire-extinguishing properties of water. The volume of the tank with the foaming agent does not exceed 6% of the total possible water supply at the SST-AU.

The tank heating system is designed to provide the required operating temperatures for all liquids used. For heating, a different heating principle can be used, both with the help of electric heating elements that heat the liquid in the tank, and diesel heaters that heat individual tanks or the entire volume inside the body.

To supply anti-icing fluid, pumps are used that do not destroy its properties (diaphragm) with a hydraulic actuator. The pump delivers fluid to a pipe leading to nozzles mounted on a telescopic boom. The nozzle provides the necessary jet configuration for de-icing.

The anti-icing boom is a multi-link manipulator with 6 or more degrees of freedom, which allows you to raise the deicer nozzle to a height of 25 meters and provides a machining radius sufficient to flood the aerodynamic surfaces of the aircraft (wings, plumage, fuselage, etc.). The drive of the individual links of the boom is carried out by hydraulic cylinders and hydraulic motors.

The fire pump is driven by a hydraulic motor. He supplies water to the foam communications. Consumption characteristics of the fire pump should ensure the supply of OTS through the fire monitor at least 60 l / s. The same pump is used to create a vacuum to accelerate the injection of water into tanks.

The gun barrel is mounted on the body near the cab. When using the SST-AU in the fire engine mode, the fire monitor is extended to its working position and controlled from the driver's cab. The gun barrel provides the supply of OTC in all the required modes (compact jet, foam jet, spray jet, etc.). The maximum feed range of the OTS with a compact jet should be at least 60 meters.

Means of hitching of the cleaning equipment are located in front of the SST-AU, under the driver's cab. Attachment points allow you to drive up to attachments (snow blade, screw rotor, brush, etc.) and attach it to one person. Hydraulic hoses are attached to attachments with quick couplings.

The air compressor is driven by a hydraulic actuator, creates air pressure for the system of blowing debris on the ground in the sweeper mode and the system of blowing snow from the aerodynamic surfaces of the aircraft in the deicer mode. To blow away garbage, air is supplied to a special rotary nozzle located at the rear of the SST-AU. For blowing snow, air is supplied to the pipeline located on the boom.

Hydraulic system - a system of pipelines, electrohydro valves, a hydraulic tank, distribution combs, a filtration system, which serve to supply the necessary pressure and flow of hydraulic fluid to the actuating units.

The electrical system is designed to start the engine and supply electric current to the actuating elements and the electronic control system.

The video surveillance system consists of cameras located on the main movable elements of the SST-AU (rear and front of the body, boom, gun mount, etc.) and is designed to transmit video to the driver’s cab.

The electronic control system is a special hardware-software complex that allows controlling all the movements of the SST-AU in manual, semi-automatic and automatic mode.

In the airfield tractor mode (main mode) of the SST-AU, all additional equipment is in a folded (retracted) state and serves as an additional ballast to increase the weight of the SST-AU in order to provide the necessary traction characteristics for different coefficients of adhesion to the airfield surface. The maneuverability and traction of the tractor is ensured by using a hydrostatic transmission with four or more rotary motor wheels.

In machine mode for anti-icing processing of aircraft (deicer) SST-AU is used in the autumn-winter period (when anti-icing processing of aircraft is required). During this period, instead of water, pre-mixed and heated anti-icing liquid (premix) is poured into the ballast tanks, or separately water and type IV anti-icing liquid with proportional mixing. The tanks have a heating system that allows you to maintain the required temperature of the anti-icing fluid during operation, as well as during parking when the machine is connected to an external power source. As a device for supplying anti-icing fluid, a hydraulic pump and a pipeline with a movable nozzle on a cantilever design with swivel joints (a boom) are used. A video surveillance system is installed on the boom, the image from which is transmitted to the driver’s cab (the cab remains stationary during aircraft processing). In addition, the SST-AU has a system for creating air pressure (flow), which is used to blow dry snow without the use of liquids. SST-AU allows to perform anti-icing processing of aircraft in automatic and semi-automatic mode according to algorithms pre-programmed for different types of aircraft using software that uses images of the aircraft surface from a video surveillance system. The transition from the aerodrome tractor mode to the SST-AU deicer mode does not require any additional actions by technical personnel, except for controlling the driver from the cockpit, therefore the aircraft can be de-iced using the SST-AU immediately after the aircraft is installed (towed) into place (parking) for de-icing treatment.

In the fire engine mode, the SST-AU provides delivery and, if necessary, supply to the fire zone or for cooling the aircraft fuselage of water or fire extinguishing composition (OTS). The boom (manipulator) is used to feed OTC to inaccessible places or directly to the fire site. In the folded state, the extreme part of the manipulator boom with the nozzle is used as a fire monitor to feed the OTS into the fire zone from a distance of up to 70 meters.

In the cleaning (washing) machine mode, the SST-AU is used in the spring-summer period (when anti-icing processing of the aircraft is not required). Water is supplied under pressure using the same pump that is used to supply the anti-icing fluid or a separate pump.

Regardless of the season, an attachment with hydraulic drive can be installed on the SST-AU, which allows for cleaning the airfield (snow blade, screw rotor blade, mechanical brush, etc.). The system for creating air pressure and controlling its flow is used to clean the airfield (blowing out small debris).

Work description:

In towing mode, a towing carrier (not a structural element) is attached to the SST-AU towing device, which is connected to the VS. The SST-AU moving along the surface of the airfield using a hydrostatic transmission and control system creates traction and tows the aircraft to the desired point.

In the fire engine mode, the SST-AU moves along the airfield and serves to deliver OTS to the fire site. Arriving at the fire site can serve as an additional capacity for a full-time fire engine or independently submit OTS. To do this, the fire pump is turned on, which supplies water to the foam communication. In the foamer, water is mixed with a foaming agent and fed into the gun barrel, from where it is fed into the fire in the form of foam.

In deicer mode, an arrow is extended from the SST-AU, which is controlled by the driver from his workplace using the video surveillance system. Moving along the aircraft and moving the nozzle, the aircraft is de-iced.

Cleaning the airfield is carried out using mounted cleaning equipment. The dump is shifted by large debris or snow, the force is created by the movement of the SST-AU, the rotation of the dump by the hydraulic cylinders on the hitch nodes. The brush rotates with the help of a hydraulic motor, which is connected to the hydraulic system by quick disconnect connections. A jet of water during movement washes the surface of the airfield, water pressure is created by the water lines of the fire pump.

Blowing out small debris and dry snow is carried out from the nozzle from the compressor during movement.
