The analysis of known technical solutions in this technical field showed that the claimed technical solution has features that are not in the analogues, and their use in the claimed combination of essential features allows to obtain a new technical result. Therefore, the claimed technical solution meets the conditions of patentability "novelty" and "inventive step". The technical solution is illustrated by drawings:

FIG. 1 - Automatic machine for repairing damaged sections of the road surface, side view;

FIG. 2 - the same, bottom view;

FIG. 3 - the head of the manipulator in the working position;

FIG. 4 - the head of the manipulator in the context;

An automatic machine for repairing damaged sections of the road surface (Machine) consists of a self-propelled chassis that contains a frame 1, wheels, an engine compartment with a power unit, gearboxes, and a driver’s cab. The transmission ensures the movement of the Machine at high speeds (up to 90 km / h), and also ensures the movement of the Machine at ultra-low speeds.

On the chassis mounted tank 2 for the repair composition with a device for supplying it, a compressor that produces compressed air, a tank with fuel connected to a device for heating the air stream. Fuel can be either combustible gas or diesel fuel.

Repair composition can be both in liquid form and in solid.

In the case when the repair composition is in liquid form, the container 2 for the repair composition has heat-insulating walls and a heating system so that the repair composition inside is in a heated liquid state.

When the repair composition is in solid form, a heater is provided in the head 3, melting the solid repair composition immediately before application to the surface to be repaired.

The machine is equipped with a rotor brush 4 for cleaning the roadway and a diagnostic sensor 5 of the roadway installed with the possibility of vertical movement, and at least one optical sensor 6. The brush 4 and sensor 5 have two positions in height: transport - maximally raised up , and working - in contact with the roadway. The brush 4 can be rotated in a horizontal plane (to remove dirt to the right or left).

Sensor 5 allows you to scan the lane of the road along which the Machine is moving and transmit information about the condition of the roadway, for example, about the presence of cracks. Sensor 6 provides information about the location of the Machine relative to the road and engineering elements of the road, as well as adjacent surfaces, road signs, markings, borders, poles, barriers, railways, wells, etc. Sensors 5 and 6 allow you to scan the road at any time of the day. The information received from all sensors 5 and 6 is synchronized with data on the movement of the Machine relative to the roadway, as a result of which a “electronic map” of the road condition is generated in the computer (control device). The data obtained is analyzed by a computer that automatically determines the repair zone.

The machine is equipped with a manipulator for repairing damaged sections of the road surface, which contains a frame 7, a turning mechanism for working equipment made in the form of a turntable 8 rotating in a horizontal plane, a carriage 9 for lateral movement of working equipment, a carriage 10 for longitudinal movement of working equipment, and a mechanism for vertical movement of working equipment made in the form of a bar 11.

The working equipment is made in the form of a head 3 with channels.

The head 3 has a housing 12 in which are made: a channel 13 for supplying compressed air, a channel 14 for supplying a hot air stream, a channel 15 for supplying a repair composition for filling cracks, a channel 16 for feeding powder.

Channel 14 for supplying a hot air stream at the outlet is made with a chamber 17 connected to a channel 18 for removing a hot air stream. In the channel 18 there is a sensor that detects the flow of dirt, gravel, scrap of asphalt, blown out from a crack in the road surface. The outlet channel 15 of the repair composition is made with a storage chamber 19. The channels 15 and 16 are equipped with valves for regulating the supply of the repair composition and powder (not shown). The exception hardening of the repair composition is provided by blowing on the channel 15 of a hot stream of air.

The head 3 is made with a smoothing plantar surface.

The design of the manipulator allows you to work with cracks located in any direction relative to the direction of movement of the Machine.

The manipulator is connected to sensors 5 and 6 through a control device.

Machine Operation Principle

The machine continuously moves along the roadway. Sensors 5 and 6 scan the road surface. In the presence of longitudinal cracks, the head 3 of the manipulator with the help of a turntable 8, carriage 9 or carriage 10 is always positioned strictly above the crack, with the help of the rod 11, the crack is lowered and repairs.

The speed of the machine depends on the number of cracks:

a) if there are no cracks on the road - the car moves quickly,

b) if there is one crack on the road along the movement of the Machine, - the Machine moves at an average speed,

c) if on the road there are several cracks along the movement, or transverse cracks, - the machine moves at a minimum speed or stops if necessary.

If there are two parallel cracks, the machine automatically stops, repairs the first crack, then the head 3 is positioned above the second crack and repairs it.

In the presence of a transverse crack, the machine stops, head 3 is positioned along this crack and moves along it.

Then the machine starts moving again and repairs the existing cracks.

The principle of operation of the working head 3

During the movement of the Machine, the sensor 5 scans the road surface. The computer processes the data on the basis of hard software and controls the movements of the manipulator: turntable 8, carriage 9 of lateral movements, carriage 10 of longitudinal movements, rod 11 and the head 3 itself.

If there is a crack on the asphalt, the head 3 is lowered onto the roadway and moves strictly along the crack.

Through the channel 13 in front of the head 3, one or more jets of compressed air are supplied, which provide cleaning of the road surface and cleaning of the crack from dirt, rubble, etc.

Through channel 14, a hot air stream is supplied to chamber 17. Burning fuel heats the compressed air that flows through the pipe. Moreover, the chamber 17 is located strictly above the crack. The hot air stream additionally cleans the crack from dirt, gravel, etc. and prepares the crack walls for repair (heating the crack walls provides better adhesion of the repair compound). In addition, a hot air stream squeezes water out of the crack; the repair composition fills it completely. The hot air stream, clearing the crack, throws dirt, gravel, etc. away from the head 3 through the channels 18. The channel 18 sensor detects the flow of dirt, gravel, scrap of asphalt, blown out of the repair zone. If the flow of dirt has stopped (all dirt from the repair area has been removed, so the sensor does not record the flow of dirt), then head 11 continues to move along the crack. If the flow of dirt is large, then the head 11 moves very slowly, providing a complete cleansing of the crack from dirt.

Repair channel is supplied from channel 15 to accumulation chamber 19. The repair composition fills the crack and is smoothed out by the plantar surface of the head 11.

A powder (sand or other material) is supplied from channel 16, covering a fresh repair compound on a crack.

In the presence of a transverse crack, the head 11 is positioned along this crack and moves along it. The process is repeated.

An automatic machine for repairing damaged sections of the road surface allows maintaining roads in proper technical condition, increasing the speed of road repairs, eliminating road blocking during the repair period, and ensuring high-quality road surface repairs by minimizing the impact of the human factor using a computer-based repair management system based on diagnostic data and based on hard software that does not allow to violate the repair technology.

An automatic machine for repairing damaged sections of the road surface is industrially applicable and can be manufactured using modern materials and technologies.
