SU1574712A1 - Restorer of flatness of road coating - Google Patents

Abstract

The invention relates to mechanization for the maintenance of roads, in particular, to restores the evenness of the surface of not hard pavements, and is aimed at increasing the degree of evenness of the coating with undulating unevenness and saving construction materials. This is achieved by the fact that the ski supports are made in the form of a suspension distributor rigidly fixed on the front and rear parts, the front of which has consistently installed at least two rolling bodies. The mechanism for raising and lowering the blade has a swinging arm supported on the front suspension with a copying wheel, kinematically connected with the vertical-vibration recorder lever. With the last and blade interacts executive device, the blade is installed between the suspensions. 3 il.

The invention relates to mechanization for the maintenance of roads, in particular, to restores the flatness of the surface of non-rigid pavements.

The purpose of the invention is to increase the degree of flatness of the coating with undulating irregularities and to save building materials.

FIG. 1 depicts a restorer evenness mounted on a dump truck, a general view; in fig. 2 - mechanism for raising and lowering the blade; in fig. 3 - memory device for lifting and lowering the blade.

The pavement evenness restorer has two longitudinal beams 2 mounted on a dump truck 1, having the possibility of lifting into the transport and lowering into working position, attached to beams 2 front 3 and rear 4 suspensions in the form of sequentially installed /

rolling bodies 5, of which the front suspension 3 includes at least two consistently installed rolling bodies 5, located between suspensions 3 and 4 lifting and lowering relative to the beams 2, blade 6 and its lifting and lowering mechanism

The mechanism for raising and lowering the blade 6 includes a swinging arm 7 supported on the front suspension 3 with a wheel 8 which copies the undulating unevenness of the road, for which the front wheel of the dump truck 1 can be used, and the vibration wheel 9 transmitted by oscillation associated with the vertical oscillation recorder a horizontally arranged round rotary cassette 10 with pushes 11 located along its outer contour, the position of which in the cassette 10 is fixed to brake decks kami 12, compressible, for example, pnevmoel VJ

chambers 13. The last part of the mechanism is an actuating device consisting of a lever 14, on which a blade 6 with an amplifier for raising and lowering it 15 is fixed and a roller 16 contacting with push rods 11 16. A second end lever 14 is fixed on the rear suspension 4.

The pavement evenness restorer works as follows.

Loaded with a repair building material, such as rubble, a dump truck 1 with longitudinal beams 2 pressed into the transport position is installed in the restored work area, beams 2 are lowered into a working position in which the front 3 and rear 4 hangers, similar to a ski support, rest on the upper sections (points) undulating irregularities (potholes), the lower edge of the blade 6 is lowered to this bearing surface of the suspensions 3 and 4, and the dump truck body 16 is raised and part of the repair material is poured onto the repaired road surface between the blade 6 and the front suspension 3.

The dump truck 1 begins to move forward at low speed, while the blade 6 moves the repair material in front of it. If a hole is in front of the copying wheel 8, as the dump truck 1 advances, it gradually lowers, simultaneously pushing out the swinging arm 7 with the copying wheel 9 with the second end of the cassette 10 pushing rods 11 of the cassette 10. The rods 11, pass the copying wheel 9, clamp the brake shoes 12 by means of pneumatic chambers 13 In this position, the rods 11 rotate with the cassette 10 and, after reaching the roller 16, allow it to lift the blade 6 fixed to the lever 14 with the help of an amplifier 15. In this case the rotation of the cassette 10 is consistent with the distance traveled m blade 6, which will begin its rise above the beginning of the pothole, creating a layer of repair material above it, taking into account its shrinkage upon subsequent compaction by means of compaction or vehicle wheels

their movement on the road after sealing potholes on it.

 As soon as the polishing wheel 8 passes the defective place on the road, it rises to the level of the support of suspensions 3 and 4, and the blade 6 descends to this level.

The push rods 11 pass the roller 16, release and lower into the neutral position and, when passing over the copy wheel 9, are fixed in the position required for controlling the blade 6.

At a meeting with a subsequent wave-shaped pothole, the interaction of nodes and

details of the restorer evenness repeat in the sequence.

Such an embodiment of the road surface evenness restores the minimum consumption of repair building material and the creation of a more even repaired road surface, which makes it possible to reduce the consumption of building material and increase the load capacity of roads.
