Description

The invention relates to road construction, namely, devices for repairing cracks in the road surface, and can be used both in construction and in road repair.

A device for repairing pavement (ed. Certificate of the USSR No. 536276) is known, in which an outlet with a closing device is made at the bottom of a hopper with heated bitumen mounted on a mobile frame. During operation, the molten bitumen material, flowing down onto the pallet, undergoes additional heating and then flows down the gentle slope onto the road surface.

The device allows you to fill the surface of cracks and bumps in the road surface.

The disadvantage of this device is the lack of efficiency of filling cracks and low quality, design complexity, fire hazard, inconvenience of operation.

A device is known that can improve the efficiency and quality of pouring by preliminary development of cracks, a cold milling cutter (patent RU No. 2081237), which is mounted in a casing on a basic three-wheeled chassis with steered wheels with the ability to rotate the casing relative to the frame by an angle of 180 degrees and rotate the cutter about an axis casing.

The device allows you to prepare a crack in the road surface for pouring with heated bitumen material.

The disadvantage of this device is the difficulty of controlling the cutter along the crack, the complexity of the design, the inconvenience of operation.

The closest technical solution to the proposed solution is a device for filling cracks in the road surface (patent RU No. 2279502) in combination with a milling cutter (patent RU No. 2081237), in which a boiler is installed on the frame, heated by a gas installation, equipped with a manual shutter for the release of bitumen, gas burner for heating the surface of the treated crack.

The combination of devices allows you to prepare a crack for filling, warm it with a gas burner and fill it with hot bitumen.

The disadvantage is the complexity of the design and mechanisms, fire hazard, inconvenience of operation.

The invention is aimed at eliminating these drawbacks, namely, at simplifying the design and mechanisms, at reducing fire hazard and improving operating conditions.

An object of the invention is to simplify the design and mechanisms.

The technical result is achieved by the fact that the wheels are electrically driven to move and rotate, transverse guides are made on the frame, on which controlled trolleys are movably mounted: a milling installation and a hose end of an industrial vacuum cleaner connected to a litter bin created by the milling installation are located on the first guide trolley which is stationary on the frame; an electric industrial hair dryer and a filler dispenser connected by a flexible pipe to the filler hopper are located on the trolley of the second rail. On the frame there is also a power station with an internal combustion engine or a connector for connecting external power supply, a control unit for wheels, bogies, a milling unit, an industrial vacuum cleaner, an industrial hairdryer and a dispenser, and a unit for tracking the direction and speed of movement. To simplify the control system of the device, a remote control can be additionally installed on the frame for manual control of wheels, bogies, a milling unit, an industrial vacuum cleaner, an industrial hairdryer and a dispenser.

Thus, the invention has the following essential features that are common with the essential features of the prototype:

1. A frame on wheels on which all mechanisms can be installed;

2. Milling installation for crack development;

3. Installation for heating the air supplied to the crack;

4. Hopper with aggregate for cracks with a flap at the outlet.

The present invention has the following differences from the prototype, which determines the compliance of the technical solution with the criterion of novelty:

1. Transverse guides are installed on the frame, on which guided carts for various mechanisms are movably mounted;

2. The electric milling installation and the hose end of the industrial vacuum cleaner, connected by a flexible pipe to the litter bin created by the milling installation, are located on the trolley of the first rail with the possibility of moving left / right from the longitudinal axis of the frame;

3. An electric industrial hair dryer and a filler dispenser connected by a flexible conduit to the filler hopper are located on the trolley of the second rail with the possibility of moving left / right from the longitudinal axis of the frame;

4. On the frame is a power station with an internal combustion engine or a connector for connecting external power supply;

5. On the frame is a control unit for wheels, bogies, a milling unit, an industrial vacuum cleaner, an industrial hairdryer and a dispenser;

6. On the frame is a tracking unit for the direction and speed of movement;

7. An additional remote control for manual control of wheels, bogies, a milling unit, an industrial vacuum cleaner, an industrial hairdryer and a dispenser can be additionally installed on the frame.

The prior art does not know the distinctive essential features of the claimed invention, characterized in the claims, which confirms its compliance with the condition of patentability "inventive step".

The device is shown schematically in FIG. 1 - arrangement of mechanisms on the frame (top view), in FIG. 2 - arrangement of mechanisms on the frame (side view).

The device comprises a frame 1 on wheels 2 with an electric drive of movement and rotation, the first 3, second 4 guides located transversely to the longitudinal axis of the frame. An electric milling unit 6 and a tip 7 of a hose 8 of an industrial vacuum cleaner 9 connected to a hopper 10 for litter created by a milling unit 6, which is stationary on the frame 1, are located on the trolley 5 of the first guide 3; On the trolley 11 of the second guide 4, there is an electric industrial dryer 12 and a filler dispenser 13 connected by a flexible conduit 14 to the filler hopper 15. On frame 1 there is also a power station 16 with an internal combustion engine or a connector 17 for connecting external power supply, a control unit 18 with wheels 2, trolleys 5, 11, a milling unit 6, an industrial vacuum cleaner 9, an industrial hairdryer 12 and a dispenser 13 and a tracking unit 19 for direction and speed of movement.

To simplify the control system of the device, a remote control 20 can also be installed on the frame for manual control of wheels, bogies, a milling unit, an industrial vacuum cleaner, an industrial hairdryer and a dispenser.

The device can operate in automatic mode and in manual control mode.

Before starting work, the power station 16 is started and all the blocks and mechanisms are connected to the power supply. The hopper 15 is filled with liquid aggregate, for example a polymer-bitumen composition (patent RU No. 2522618). The peculiarity of this composition is that it hardens when an initiating additive is added in the presence of atmospheric oxygen, which allows it to be stored in a sealed hopper without air access for more than 8 hours without changing viscosity. At temperatures above -15 ° C, the viscosity of the composition is 10 ^-3 Pa · s, which allows it to spontaneously pour out of the hopper. In a fluid state, the composition does not interact with polytetrafluoroethylene (Teflon) or polypropylene, which prevents the composition from sticking to dispenser elements made of polytetrafluoroethylene or polypropylene.

To implement the automatic mode, a crack on an asphalt surface is pre-marked with paint, for example, white. Tracking unit 19 is configured to track the direction of the marked line. Devices and algorithms for tracking and generating information for control unit 18 are used in robotics (for example, the Internet resource htth: //przrobotl2.http: //blogspot.ru/).

The control unit 18 generates signals and supplies power to the drives of the wheels 2, to the trolley 5, which, moving along the guide 3, takes place over the white line. At the signal of the control unit 18, an electric milling unit 6 is launched, which develops a crack to a predetermined depth and width, for example, 100 mm in depth and 20 mm in width. For these parameters, a very powerful milling drive is not required.

At the signal of the control unit 18, a vacuum cleaner 9 is started up, which, through the tip 7 and the hose 8, sucks the rubbish created by the milling unit 6 and puts it in the hopper 10.

At the signal of the control unit 18, the drive of the carriage 11 is started, which, moving along the guide 4, takes place over the groove created by the milling unit 6, the industrial dryer 12 is launched into operation, which pumps hot air into the groove cleaned of debris.

At the signal of the control unit 18, the dispenser 13 is started to work, which feeds the polymer-bitumen composition by gravity into a cleaned, heated and drained groove.

As the groove is filled with the polymer-bitumen composition, movement and rotation signals are sent to the wheel drives 2 and the entire structure moves along the marked line. Since the crack can generally have bends, the position of each trolley on the rail changes accordingly, so that each mechanism is above its working area.

The tip 7 of the vacuum cleaner is located in close proximity to the mill 6, behind it, and the output of the industrial hairdryer 12 is located in close proximity to the dispenser 13, in front of it.

In the manual control mode, it is necessary to visually monitor and adjust the speed and direction of the wheels, the movement of the carts on rails and the operation of the milling installation, vacuum cleaner, industrial hair dryer and dispenser.
