Abstract

Use: laying repair material during construction and maintenance of roads. SUMMARY OF THE INVENTION: The assembly comprises a base means, a blade-planner, a ripper, a compactor, a container for a consumable material and a hopper with a bottom mounted on it. The latter is made in the form of a loading and unloading shield that is rotatable in a vertical plane and joined to the front wall of the bunker. The compactor is connected to the hopper and is a vibrating plate with a toothed external contour and an aperture covered by a part of the shield. The overlapping part of the shield may have a smooth bend down. 3 il.

Description

The invention relates to the construction and maintenance of roads, namely, devices for the repair of road surfaces.

A known machine for repairing asphalt concrete pavements, containing a self-propelled chassis, on the frame of which are mounted a bunker with a tray, containers for receiving and liquefied gas, an infrared heater, a scheduler and vibratory rollers.

The disadvantages of this machine are the limited capacity for the repair material and, consequently, the need for repeated flights. The vibratory roller for compaction is ineffective, as it creates waves on the canvas.

The closest technical solution is a pavement repair unit, including a machine base, a bunker for repair material with

conveyor, ripper, blade-planner with a variable angle of inclination of the working plane and a compactor, made in the form of a roller.

The disadvantage of this unit is also the limited capacity for the repair material. An additional device, a conveyor belt, is required to deliver the material to the repair site.

In addition, the roller does not provide the required quality of the planned surface: it creates waves.

The aim of the invention is to improve the quality of laying repair material and simplify the design.

This goal is achieved by the fact that in the pavement repair unit, which includes the basic means, the dump mounted on it — a planner, a ripper, a compactor, a container for a consumable material and a hopper with a bottom

made in the form of a loading and unloading shield joined to its front wall that is rotatable in a vertical plane, and the compactor - in the form of a vibrating plate connected to the hopper with a gear external contour and an aperture overlapping part of the shield. At the same time, the overlapping opening in the vibrating plate of the shield has a smooth bend down.

FIG. 1-3 shows a pavement repair assembly.

The pavement repair unit contains the base tool 1 with the ripper 2, and the planner blade 3 with a variable angle of inclination of the working surface. On the base tool 1 by means of levers 4, a hopper 5 is mounted for repair material. A vibrating plate 7 with a vibrator 8 is attached to the front wall 6 of the bunker 5. A discharge hole 9 is made in the vibrating plate 7. The bottom 10 of the bunker 5 is made in the form of a loading and unloading shield and can be rotated around the axis 11 using hydraulic cylinders 12. The front part 13 of the bottom 10 of the hopper overlaps discharge port 9 and bent in the direction of discharge. The vibrating plate 7 is made in the form of a circle or a rhombus and its lateral sides are equipped with teeth 14. On the base tool 1, the containers 15 and 16 are installed for water and in the gumming means.

The unit works as follows.

By lowering the ripper 2, the section of the repaired blade is loosened, its alignment is performed by the blade 3. Loosening can be carried out by moving the machine base back and forth, respectively, setting the teeth. The hopper 5 is loaded with repair material (gravel)

a dump truck or self-loading from a previously prepared embankment by inserting into the embankment a bunker 5 with the bottom lowered 10. Above the repaired section of the vibrating plate 7 is raised to the desired height of backfill. When the bottom is lifted by 10 hydraulic cylinders 12, crushed stone is poured out through the discharge opening 9 to the section being repaired. Then the bottom 10 is lowered. The profiling is carried out by moving the base means 1. The teeth 14 of the plate 7 are used to cut the protrusions while simultaneously filling the depressions. The compaction is carried out by the vibrating plate 7. The vibrating plate 7 is symmetrical and the work on profiling and compaction can be performed by moving forward and backward. From the containers 15 and 16, water is watered or poured at the right time. The control of the fluid supply is remote.
