Description

The utility model relates to road machines and units used in the construction, reconstruction and repair of roads and airfields, used to supply bitumen-containing materials to the longitudinal joints of asphalt concrete pavements.

Known devices for applying bitumen-containing materials to the longitudinal joints of strips of asphalt pavement during their laying.

For example, a device is known for pre-treatment of a repair and/or connecting seam in road construction before laying a bituminous connecting tape on the seams of asphalt concrete pavements, described in patent EP 2620550, priority dated 01/23/2013, IPC E01C 23/09, which is made in the form of a vessel of high pressure, equipped with a valve designed to relieve excess pressure, as well as a ball valve designed to change the pressure in the vessel, providing a dosed supply of bitumen-containing material along the edge of the asphalt concrete pavement.

Also known is a device for applying bitumen-containing and solvent-free porous filler for compaction of asphalt concrete pavements, described in patent EP 3156544, priority dated 10/06/2016, IPC E01C 19/16, E01C 19/17, E01C 23/09, adopted as a prototype, which is also made in the form of a high-pressure vessel equipped with a valve designed to release excess pressure, as well as a ball valve designed to change the pressure in the vessel, providing a dosed supply of bitumen-containing material along the edge of the joint of the asphalt concrete pavement.

A common advantage of these technical solutions is the possibility of mechanizing the process of joining the joints of asphalt concrete pavement strips.

At the same time, both analogues also have the disadvantage that the use of vessels operating under high pressure and into which hot bitumen-containing materials are poured affects the safety of workers during work on the joints of asphalt concrete pavement strips.

The technical problem to be solved is the lack of safety when performing work using known devices designed for mechanized application of bitumen-containing materials at the joints of asphalt concrete pavements.

The technical result of the claimed utility model is to increase the efficiency and quality of applying bitumen-containing materials to the longitudinal joints of asphalt concrete pavement strips.

The specified technical result is achieved through the use of an automated module for applying bitumen-containing materials to the longitudinal joints of asphalt concrete pavement strips, which is installed on an asphalt paver used in the construction, reconstruction and repair of roads and airfields, while the automated module includes a frame on which a working container is installed, designed to accommodate bitumen-containing materials in it, closed with a cover that provides access inside it for the purpose of pouring liquid bitumen-containing materials, including during the operation of the asphalt paver, while to ensure better flow of bituminous materials to the bottom of the working container, a a vibration motor designed to transmit vibration to the working container, the operation of which is controlled by the control unit, and inside the frame there is a pump, the inlet of which is connected by means of a receiving hose to the outlet of the working container, and the operation of the pump is also controlled by the control unit, with At the same time, a supply hose is installed at the outlet of the pump, equipped with a nozzle designed to apply bitumen-derived materials along the joints of the asphalt concrete pavement; for this, the nozzle is fixed to the asphalt paver, for example, using a bracket; vibration motor on the frame.

The control unit can also be connected to the onboard system of the asphalt paver in order to regulate the supply of bituminous materials in an automated mode, depending on the speed of its movement.

An automated module for applying bitumen-containing materials to the longitudinal joints of asphalt concrete pavement strips operates as follows.

Before use, a bitumen-derived material is poured into the working container, intended for its application along the junction of asphalt concrete pavement strips.

Then, using the control unit, manually or in automatic mode (if it is integrated into the onboard system of the asphalt paver), the pump is turned on, which sucks off the liquid bitumen-derived material from the working tank with the help of the receiving hose and directs it with the help of the supply hose through the nozzle to the junction of the asphalt concrete pavement strips continuously a uniform strip of a given width and thickness immediately before laying the second strip, joined with the first strip of asphalt concrete pavement.

Thus, the application of the proposed technical solution makes it possible to exclude the use in the design of vessels operating under high pressure, into which bitumen-containing material is poured, while it is also possible to integrate the control unit of the automated module into the on-board system of the asphalt paver, which ensures complete automation of the work on applying bitumen-containing materials on longitudinal joints of strips of asphalt concrete pavements.

The design of an automated module for applying bituminous materials to the longitudinal joints of asphalt concrete pavement strips is shown in Fig. 1.

The automated module for applying bitumen-containing materials to the longitudinal joints of asphalt concrete pavement strips includes a frame (1) on which a working container (2) is installed, designed to place bitumen-containing materials in it, closed with a cover (3), which provides access inside it for the purpose of pouring liquid bitumen-containing materials, while to ensure better runoff of bitumen-derived materials, a vibration motor (4) is installed on the frame (1) under the working tank, the operation of which is controlled by the control unit (5), and a pump (6) is located inside the frame (1) , the inlet of which is connected by means of a receiving hose (7) to the outlet of the working container (2), and the operation of the pump (6) is also controlled by the control unit (5), while a supply hose ( 8), equipped with a nozzle (9) designed to apply bitumen-derived materials along the joints of the asphalt concrete pavement, for which the nozzle is fixed on the paver, for example, using a bracket (10).

In addition, between the tank (2) and the frame (1), vibration dampers (11) can also be installed to prevent the transmission of vibration from the vibration motor (4) to the frame (1).

The control unit (5) can be connected to the onboard system of the asphalt paver in order to regulate the supply of bitumen-derived materials in an automated mode, depending on the speed of its movement.
