SU916641A1 - Equipment for laying asphalt-conrete mixtures - Google Patents

Description

The invention relates to the construction, namely, devices for laying asphalt mixes.

Known paver, containing a self-propelled chassis, on the frame of which is mounted the feed hopper, distributor and vibrating bar with the mechanism of their vertical movements mounted on the frame, the hopper is made of articulated sections, and the fixed section is equipped with a dispenser in the form of a bolt installed in its lower part [1 ].

The disadvantage of the paver is the great complexity of the work when laying concrete mix. \

The most. close to the proposed technical entity is equipment for laying asphalt mass, containing a hopper with a drum feeder, a vertical fixed frame and a movable frame mounted on it to move, on which is attached a bunker with a rotatable receiving wall and a lid, which is possible by means of hydraulic cylinders recline for entry of a dump truck [2].

A disadvantage is the need for equipment, except the equipment for laying concrete mixtures, an additional set of equipment for laying the coating, which increased ₅ Vaeth truboemkost road repair.

The purpose of the invention is to reduce the complexity of the repair of pavements.

This goal is achieved by the fact that ¹⁰ equipment for laying asphalt mixes, containing a bunker mounted on the chassis of the base machine

, in its lower part with a bolt, equipped with a roller copier mounted on the bunker

15 calibrating valve sealing roller, and the bunker is made with vertical dividing walls, the shutter is composed of separate sections, the number of which is equal to the number of compartments of the bunker.

FIG. 1 shows equipment for

²⁰ laying asphalt mixes in the transport and working positions, general view; in fig. 2 - the same, rear view in the working position; in fig. 3 - section A — A in FIG.

The equipment consists of a bunker 1, which is attached to the rear of the body 2 of the dump truck. In the lower part of the bunker is divided into sections by vertical dividing partitions, and the shutter 3 is made of composite, the opening of which is done with the help of handles 4. In the lower part of the bunker are kalibuyuschie valve 5 and the sealing rollers 6.

To maintain the profile of the road being repaired with an attachment, a roller copier 7 is rigidly connected. For balancing the equipment, a slab attachment is attached to the front part of the truck body 8.

The device works as follows.

Asphalt concrete mix from the body of the dump truck is unloaded into the sectional bin of attachments and when the car moves over the repaired road section it unfolds with a layer thickness adjustable by a calibrating flap with repetition of the coating profile set by the roller copier. The mixture is simultaneously compacted with rollers. The width of the laid strip is regulated by the inclusion of one or more valves.

The proposed equipment allows to reduce the complexity of work in the repair of pavements.
