Description

The utility model relates to the field of road construction and can be used for transportation, preparation, unloading and laying of highly viscous thermoplastic materials, in particular mastics, in the repair of cracks and seams of the road surface or airfield surface.

A device for transporting, preparing, unloading and stacking thermoplastic materials is known, which comprises a frame mounted on the chassis, with a pivotally mounted heat-insulated casing, with a heated tank placed in it, with a loading hatch and a mixer. There is a cut-out drive flap on the end wall of the casing. Declares the area of the discharge hatch. The mixer has a rotation drive, which provides a change in direction and frequency of rotation of the mixer. The device is equipped with a mechanism for power take-off from the engine, a temperature sensor and instrumentation, a device for distributing and stacking thermoplastic material in the form of a rotary tray, a device for preparing the surface for laying in the form of an air duct with a heated air flow controller and a cutter for trimming edges. Nozzles are used as a device for distributing thermoplastic material. There is a lift mounted on the frame to ensure rotation of the casing, flame tubes for heating the tank, a chimney for the output of combustion products (US Pat. RF No. 2141549 from 03.25.98 publ. 20.11.99).

The disadvantages of the known device are:

- the device is a batch-type installation - pre-prepared thermoplastic material is loaded into it, transported to a place with maintaining the temperature, then completely unloaded. This mode of preparation of a thermoplastic material cannot be used when filling cracks (seams) in coatings due to the low rate of material consumption;

- the time of use of warm thermoplastic material is limited, which reduces the time of filling cracks;

- the device cannot autonomously work on the repair of coatings away from devices that carry out preliminary preparation of thermoplastic material;

- the method of heating a thermoplastic material using flame tubes does not contribute to high-quality cooking due to areas of overheating or underheating of the material;

- the device is not able to lay the thermoplastic material in a relatively narrow and winding crack of the coating due to the lack of visibility of the crack under the machine and the insufficient maneuverability of the self-propelled chassis, especially in the direction transverse to the direction of its movement.

Utility model No. 55378 of March 28, 2006, publ. 08/10/2006, which is the closest analogue selected for the prototype.

A disadvantage of the known device is that the placement of electric heaters inside the walls (in particular, casting) complicates the design, requires the manufacture of injection molds and makes repairs very expensive, because access to failed electric heaters located in the walls of the tanks is not possible, therefore, when repairing, the replacement of the whole unit (the entire tank) is required.

The technical result of the claimed utility model is to reduce the cost of repairs, simplify temperature adjustment and maintain it in a narrow range throughout the working cycle, increase manufacturability in manufacturing, which in turn reduces the cost of production of elements and components that make up the device.

The device operates as follows.

All devices involved in the transportation, preparation, unloading and laying of highly viscous thermoplastic materials and in the preparation of cracks (seams) of the repaired coating are placed on a self-propelled chassis (1) and thus delivered to the repair site.

Preparation of thermoplastic material for pouring cracks (seams) is as follows.

The thermoplastic material (mastic) in the solid state (in briquettes or cassettes) is loaded into loading containers (10) and, getting on the heater first (23), softens and then flows down to fill loading containers (10), heats up to a certain temperature due to hot air coming from electrical devices (20) into the gaps between the bottoms and walls of containers and casings (21) with thermal insulation (22). Because Since all containers are in thermally insulated casings, there is no heat loss. Then, the molten mastic flows by gravity through pipelines into the conditioning container (11) from which it flows into the container of the finished thermoplastic material (12) using a pumping device (pump) (16). When the mastic moves upward along the walls of the conditioning container, it is heated to the required temperature value of 185 ° ± 5 ° C (the required temperature value is set depending on the highly viscous thermoplastic material used) and is constantly mixed by an electric mixer (14) (15). The mixer in the conditioning tank is designed so that the mastic flows as densely as possible along the walls of the conditioning tank for better heating. Constant mixing contributes to a more uniform heating of the mastic throughout the volume. At the same time, in all containers, including the capacity of the filling trolley (26), the heating temperature is controlled using the heating control and control unit (13). For this, temperature sensors (17) are installed in all tanks. Having reached the required condition, the mastic enters the container of the finished thermoplastic material (12), it also carries out heating, including the drain pipe (18) and mixing, thereby the mastic is always in a state ready for use. Since the heating of the containers is electric, which is provided by an autonomous source of electricity (4), for example, in the form of a generator, mastic can be prepared during the trip to the repair site, which reduces the time of the repair itself.

The preparation of cracks (joints) of a road or airfield pavement to be repaired is as follows.

Milling is carried out using a device for cutting the edges of cracks (seams) (6). Then it is blown with hot air under pressure with the simultaneous flashing of the edges using a device for blowing and fusing cracks (seams) (7).

The mastic is ready for use (the readiness of the mastic, i.e. when the required temperature is reached, is indicated by a light that lights up on the control panel of the heating and control unit), opening the valve (19) on the drain pipe from the container of the finished thermoplastic material (12) ( 18) load (by gravity) into the capacity of the filling trolley (26). The container is located on the frame of the filling trolley (25) in the casing (21) with thermal insulation (22) and the decorative casing (9), has a nozzle (27). The filling trolley (3) moves freely on wheels (30) to the required place to repair the crack (seam), while the mastic is heated, because the capacity of the filling trolley (26) is heated in the same way as all other containers with the help of an electric device (20) and is mixed with an electric mixer (14) with an electric drive (15). Thus, the finished conditional mastic through the nozzle (27) enters the prepared crack (joint) under pressure with the aid of an unloading device (pump) (28) with an electric drive (15), at the same time, a joint is formed using a smoothing element (29), which covers the nozzle and is controlled by a lever (31) located at the handle of the filling cart. The filling trolley is connected to the heating control and control unit with a multicore flexible cable (32).

The flow of hot air in figure 2 is shown by arrows, while the removal of this air is carried out in a safe area for staff.

In a specific application example, a “Gazelle” automobile was used as an electric power source — a generator of a welding unit (4), for cutting edges of a crack (seam) —separator of cracks (seams) (6) and a device for blowing and fusing cracks (seams) (7) .

The inventive device achieved a technical result, namely, reduced repair costs, because all containers are heated by an electric device that supplies hot air of the required temperature, which is set by the temperature controller of this device depending on the thermoplastic material (for example 185 ° C or 210 ° C), i.e. from the design of containers (walls, bottom), devices are excluded that can fail and the process of setting the required temperature and maintaining it in a narrow range throughout the entire working cycle is facilitated. As a result, the elements and components of the device are more technologically advanced in production, which in turn reduces the cost of their production and saves the cost of repairing the road surface.
