SU441386A1 - Vibrating channel paver body - Google Patents

Description

one

The invention relates to vibratory compactors for concrete mixers of concrete pavers used for the construction of concrete channel linings.

The vibrating organ of the channel paver is known, which includes a vibrating bar suspended from the frame on elastic shock absorbers with a bottom having a front inclined and rear smoothing part and rigidly fixed ribs protruding in the direction of the concrete paver's bunker. However, such a vibration body does not allow to obtain a concrete lining that is sufficiently dense and homogeneous over the cross section of the channel due to sliding of the mixture along the slope under the vibrating bar and its insufficient compaction.

The purpose of the invention is to prevent the concrete mixture from sliding down the slope and to improve its compaction during the molding of the concrete channel lining.

This is achieved by the fact that on an inclined part of the bottom of the vibrator, the ribs are rigidly fixed, the bottom surface of which is located in the same plane with the smoothing part of the bottom of the vibrator.

FIG. I schematically shows the vibrating organ of the paver in section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The proposed vibrating body

The paver of the channels consists of a vibrating bar 1, having a bottom with an inclined front 2 and a rear railed 3 parts. On the inclined part 2 of the bottom of the vibrator, the ribs 4 are rigidly mounted, projecting with the front ends into the stacker bunker 5. In order to obtain a uniform transmission of vibration from the vibrating bar to the concrete mix and to improve its flow from the bunker 5 under the vibrating bar, the front ends of the fins 4 are made dylan shaped. Along the length of the sloping part of the bottom of the vibrating rod, the ribs 4 have a variable height, which makes it possible to achieve a different intensity of vibration impact on the concrete mix. This helps to improve the compaction of the mixture and prevent it from sliding down the channel's slope. The bottom surface of the ribs 4 is located in the same plane with the smoothing part 3 of the bottom of the vibrator. The vibrobrus 1 is suspended from the frame of the stacker 6 on elastic shock absorbers 7.

In the course of the paver's operation, the concrete mixture from the bunker under the action of vibrational vibrations of the vibrating bar intensively flows under its inclined part, where the mixture layer is worked deep and simultaneously kept from slipping along the slope due to the ribs protruding below the inclined part of the vibrator bottom. This makes it possible to obtain a concrete lining that is denser and more uniform across the channel.
