Description

The technical field to which the utility model belongs.

The utility model relates to road engineering, in particular to equipment for the regeneration of pavement.

State of the art

A device for heating the roadway (patent RU 143087 publ. 07/10/2014) containing a trolley, a heating device with a microwave metal screen mounted on a trolley and with a quarter-wave loop system inserted into the hard screen around the entire perimeter of the hard screen is known.

The disadvantage of this device is the inability to reproduce the technological operations of regeneration by a single device.

It is also known a device for the regeneration of asphalt concrete pavement, selected for the prototype (patent 2039145 publ. 09.07.1995), which contains a frame with a chassis. A microwave energy generator is placed on the frame, a horizontally located emitter with a protective screen along its contour and on top of the frame. In the zone of the emitter on the frame perpendicular to its longitudinal axis, pipes for the distribution of surface-active substances and mixing organs are installed.

A disadvantage of the known technical solution is the low reliability of the device due to the large load on the frame and inconvenience in operation.

Utility Model Essence

The task to which the claimed technical solution is directed is to expand the arsenal of tools that provide high-quality repair of damaged sections of the road surface due to a single mobile device.

The technical result is to increase the reliability of the device.

The technical result is achieved by the fact that in the device for the regeneration of the pavement, including the supporting structure, on which the microwave generator, dispenser and milling cutter are installed, according to the proposed solution, the supporting structure is made in the form of a platform, along the perimeter of the lower part of which there are stiffeners, and in parallel on its smaller side, a dispenser, a mill and a vibratory ruler are installed in series, while the dispenser and mill are equipped with hydraulic actuators connected by a high pressure hose to a high pressure pump lion connected to an internal combustion engine mounted on the outer part of the platform, equipped with a control unit.

Brief Description of the Drawings

In FIG. 1 schematically shows the design of a device for the regeneration of pavement, FIG. 2 shows the lower part of the platform with working bodies.

Utility Model Implementation

The device for the regeneration of the road surface contains a platform 1, on the outside of which there is a microwave generator 2 with a protective hard screen 3, which is connected to a flexible protective screen 4. The dispenser 5, the milling cutter 6 and the vibrating ruler 7 are sequentially mounted and fixed on the lower part of the platform 1. The dispenser 5 and the milling cutter 6 are equipped with hydraulic drives 8, which are connected to the high pressure pump 9 connected to the internal combustion engine (ICE) 10 using the high pressure hose 10. The ICE 10 is located on the upper part of the platform. The dispenser 5, the cutter 6 and the vibrating ruler 7 are connected to the control unit 11 and are equipped with a protective screen 12.

The device is delivered to the repair section of the road and installed over the repaired section of the road surface. The operator using the control unit 11 includes a microwave generator 2 for heating the selected defective section of the roadway. The operator monitors the temperature of the road surface and turns off the microwave generator 2 at a temperature of the road surface of 110 - 160 ° C, advances the device forward, starts the engine 10, and the hydraulic actuator 8 starts the dispenser 5. The necessary volume of the mixture is added to the heated road surface, which is determined visually using a camcorder. The dispenser 5 is turned off, the device is moving forward, the operator with a hydraulic actuator 8 starts the cutter 6, lowering it to the depth of the heated roadway to mix it with the mixture, then the cutter 6 rises to the transport position and turns off. The device moves forward, the roadway is leveled with a vibrating line 7, the device moves forward and the roadway is pressed with rollers.

The application of the proposed device allows you to create a monolithic section of the damaged roadbed and to exclude further the formation of cracks, faults in this repaired section.

Claims (1)
