Abstract

The marking module is designed for applying marking paint and reflective microspheres to the road surface in an airless way in automatic, semi-automatic and manual mode. An internal combustion engine (3) is installed on a removable frame (2), connected to a hydraulic system and a pneumatic system, and a trolley (6). The cart (6) is equipped with paint sprays (7, 9), microspray sprays (8) and a support wheel (54). Sprayer (9) is intended for manual marking. The pump (19) delivers the paint from the tank (4) for paint to the spray guns (7, 9). The pneumatic valve block (31) controls the supply of compressed air to the nozzles (7, 8, 9) and to the tank (5) for microballs. On the axis of the wheel (54), a distance sensor (55) is installed, connected to the on-board computer via the controller board (56). The controller board (56) contains a pulse counter (57), memory elements (58) and a comparator (59). The sensor (55) converts the number of revolutions of the wheel (54) into electrical pulses. The device (59) compares the number of pulses recorded by the counter (57) with the number of pulses stored in the memory elements (58) by the on-board computer. The rectangular pulse from the comparator (59) is transmitted to the on-board computer and then to the pneumatic valve block (31). So the road is marked with dashed lines of a given length. 1 s.p. f-ly, 8 ill.

Description

The marking module relates to devices for applying horizontal marking on roads or other transport surfaces, in particular, lane separation lines, restrictive and warning lines. The principle of operation of the marking module is based on the airless method of applying marking paint and reflective microspheres to the road surface under high pressure.

A device for marking roads EP 0807714-1997-11-19 is known, the principle of which is based on the airless method of applying marking paint and glass balls to the surface of the road.

This device is a carriage attached to a vehicle and having a frame. The main rail is mounted on the frame, on which a lever is mounted with the possibility of rotation in a vertical plane with spray guns and balls mounted on it, equipped with a support wheel. An internal combustion engine is mounted on the frame, connected to a hydraulic pump for supplying the working fluid from the hydraulic tank under pressure to the hydraulic motor controlling the paint supply pumps. The engine is also connected to a compressor for supplying compressed air to the glass bead tank, as well as to paint and ball nozzles. The number of spray guns and balls corresponds to the number of simultaneously applied marking strips. The device is also equipped with a paint tank and piping system.

The device described in patent EP 0807714 is the closest analogue to the marking module claimed as a utility model in terms of technical nature. However, this device does not allow the application of dashed lines of a given length in automatic or semi-automatic mode, as well as to control the traversed by the scribe

way. Drawing marking lines other than traffic lane separation lines, such as pedestrian lanes, security island restriction lines, etc., is difficult or completely impossible.

The problem solved by the claimed utility model was to create a marking module having the ability to draw dashed lines of a given length in an automatic or semi-automatic mode while monitoring the distance traveled. Another objective of the claimed utility model is the ability to apply other marking lines, except for the separation lines of traffic lanes.

The tasks are solved by the fact that a marking module is proposed comprising a frame attached to the vehicle, on which are installed: an internal combustion engine connected to a hydraulic pump and compressor; paint pump; a hydraulic motor connected to a hydraulic pump at the inlet and to a pump for supplying paint at the outlet; a trolley consisting of a lever mounted in a guide fixed to the frame and a support wheel; at least one pair of spray guns of reflective microspheres and paint is mounted on the trolley.

New in the proposed marking module is that a distance sensor is installed on the axis of the support wheel, connected to the on-board computer by means of a controller board containing a pulse counter, memory elements and a comparator.

New in the proposed marking module is also the fact that it is equipped with an additional removable spray gun for manual marking connected to a paint pump.

The marking module includes a removable frame 2 located on the vehicle platform 1, an internal combustion engine 3 fixed to the frame 2, connected to the hydraulic system and the pneumatic system of the marking module, a paint tank 4, a tank for beads 5, a cart 6 with paint spray guns 7 and ball sprays 8. The number of pairs of sprays 7 and 8 corresponds to the number of simultaneously applied marking strips. The marking module is equipped with an additional removable spray gun 9 for manual marking. The marking module also includes a control panel 10 connected to the on-board computer, a marker 11 mounted on the bow of the vehicle 1 and flashing beacons 12 for light signaling during work.

As a vehicle 1, a GAZ 3302 Gazelle car or another car of a similar type can be used. As the engine 3 is used, in particular, a gasoline engine of the brand "Honda" with a capacity of 18 hp

The hydraulic system, the diagram of which is presented in Fig. 5, consists of a tank 13 for hydraulic oil, a pressure line and a drain line.

The pressure line includes a hydraulic pump 14 connected to the engine 3, which creates a working pressure in the hydraulic system and connected through a safety valve 15 to a hydraulic distributor 16, which distributes the flow of the working fluid (hydraulic oil) to the paint mixing hydraulic motor 17 and the hydraulic motor 18 controlling the paint pump 19, as well as to the drain line.

The drain line consists of a radiator 20 for cooling hydraulic oil with an electric fan, a check valve 21 and a filter 22. To supply the working fluid (hydraulic oil) to the hydraulic motors 17 and 18, there are valves 23 and 24, and a drain 25 to the drain line.

The pneumatic system, the diagram of which is shown in Fig.6, consists of a compressor 26 connected to a receiver 27, equipped with a safety valve 28 and a drain valve 29, an oil and water separator 30, a block of pneumatic valves 31 that controls the supply of compressed air to the nozzles 7, 8, and 9, and also a ball valve 32 for supplying compressed air to the tank for beads 5.

As shown in FIG. a paint pump 19, connected to the intake 33 and through the tee 34 to the spray guns 7 and 9. Between the tee 34 and the spray guns 7, check valves 35, fine filters 36, pressure gauges 37 and bleed valves 38 are installed. Cranes 39 and 40 are used for supply of paint to the spray guns 7, and the valve 41 for supplying paint to the spray gun 9.

The pipelines connecting the elements of the hydraulic system and the pneumatic system of the marking module are not shown in the drawings or are conventionally shown.

As shown in figure 3, the trolley 6 consists of racks 42 and 43, on which levers 44 are mounted with the possibility of rotation in a vertical plane. In the upper part of the stand 42, the main beam 45 is fixed, with the possibility of longitudinal movement in the groove of the guide 46 mounted on the frame 2. The position of the main beam 45 is fixed by bolts 47 that fit into the threaded holes of the guide 46. A beam 48 is mounted on the rack 43, on which the brackets are fixed 49 and 50 with holders 51 and 52 mounted on them for paint sprays 7 and microspray sprays 8. The position of the holders 51 and 52 is adjusted using clamps 53. A block of pneumatic valves 31 is installed in the upper part of the rack 42, and on the lower end e rack 43 is fixed a wheel 54, which is mounted on the axis of the path traversed by the sensor 55.

The sensor 55 is connected to the on-board computer via a controller board 56 located in the control panel 10 (see Fig. 8). The board 56 includes a pulse counter 57, memory elements "stroke" and "pause" 58 and a comparator 59 (see Fig. 8). As a sensor for the distance traveled, in particular, an OMRON model E6B2 sensor is used. Counter 57, memory elements 58, and comparing device 59 are implemented in a single Xilinx LSI chip.

When transporting the trolley 6 is in the folded state on the frame 2 (shown in dashed lines in figure 2). In this case, the beam 45 is pushed into the guide 46 to the stop and fixed with bolts 47. Before starting work, the beam 45 is released by unscrewing the bolts 47, the beam 45 is pulled out along the guide 46 and fixed with bolts 47. The nebulizers 7 and 8 are installed by moving the holders 51 and 52 along the brackets 49 and 50, respectively, and are fixed by clamps 53.

Marker 11 is installed so that its end is directly above the preliminary marking line at a predetermined distance "A" from the longitudinal axis of the vehicle 1. The position of the marker 11 is controlled by the driver of the vehicle.

One pair of nozzles 7 and 8 is also installed at a distance "A" from the longitudinal axis of the vehicle 1. If there are several pairs of nozzles (for example, two pairs, as shown in figure 2), they are installed at a given distance "B" relative to each other friend.

The on-board computer mounted on the vehicle 1 allows horizontal marking on the roads in three modes: automatic, semi-automatic and manual. In automatic mode, the marking is carried out according to the program entered by the operator in accordance with the deployment scheme. In the case where there is no reliable dislocation scheme, it is convenient to use the semi-automatic mode. Manual mode is used for marking small sections of the road, for example, for marking pedestrian lanes.

The work of the marking module in semi-automatic mode is as follows.

When the engine 3 is started, the hydraulic pump 14 is turned on, which creates working pressure in the hydraulic system, which is transmitted to the hydraulic motors 17 and 18. The hydraulic motor 17 includes a paint mixing mechanism (not shown in the drawings), and a paint pump 19 is driven by the hydraulic motor 18. Pump 19 using the intake 33 supplies paint through a tee 34 and filters 36 to the paint sprayers 7. When operating in semi-automatic mode, the taps 39 and 40 are open and the tap 41 is closed (see FIGS. 5 and 7).

The safety valve 15 is used to prevent overpressure of the hydraulic oil entering the valve 16. When the safety valve 15 is activated, the hydraulic oil is drained through the radiator 20 and the check valve 21 into the tank 13.

Manometers 37 allow you to control the pressure of the paint supplied to the nozzles 7, the excess pressure is vented through the drain valves 38.

When the engine 3 is started, the compressor 26 is also turned on, which supplies air under pressure to the receiver 27, then the air passes through the oil and water separator 30, where it is cleaned, and through the pipeline enters the tee (not shown) and is divided into two flows. The first stream passes through a ball valve 32 and enters the tank for beads 5, the second stream enters the block of pneumatic valves 31, which controls the supply of paint and beads to the nozzles 7 and 8.

The distance sensor 55 allows for intermittent marking with strips of a given length at a certain distance from each other. When driving on the road, the sensor 55 converts each revolution of the wheel 54 into an electrical impulse. A pulse counter 57 sums the pulses and transmits information to a comparator 59, which alternately compares the number of pulses recorded by the counter 57 with the number of pulses stored in the memory elements 58. The number of pulses

it is set into memory elements 58 by the on-board computer and corresponds to the length of the strip to be painted (“stroke”) and the length of the unpainted portion (“pause”). If the number of pulses coincides, the comparing device 59 transmits a rectangular pulse to the on-board computer, which gives signals to the valve block 31, which turns on or off the supply of compressed air to the paint spray guns 7 and microspheres 8. This marks the road with broken lines of a given length. In addition, the information provided by the sensor 55 is summed by the on-board computer and converted into various data: the total length of the painted strip, ink consumption, etc.

If it is necessary to switch to the manual marking mode, the vehicle 1 is stopped, the nozzle 9 is connected to the tee 34 by means of a flexible pipeline, the ball valve 32 and the valves 39 and 40 are closed, and the valve 41 is opened. Next, start the engine 3 and make marking on the stencil.

The marking module can, if necessary, be removed from the vehicle 1 without dismantling due to the installation of all its units on the removable frame 2.
