Description

The invention relates to the field of construction industry and can be used for high-quality processing of non-hardened surfaces of reinforced concrete products molded from hard concrete mixes for civil and industrial production.

There are various smoothing machines for processing unhardened concrete surfaces of precast concrete products (1, 2). Processing known smoothing machines is carried out by the interaction of the working body with the uncured processed surface of the product.

Closest to the proposed invention is a machine for finishing concrete surfaces (RU 2204479 C2, 05.20.2003, B28B 11/08), which is a two-mass working body of a smoothing machine, consisting of a housing, a smoothing disc, a drive shaft, at the end of which there is a cam mechanism and spring.

A disadvantage of the known device is the inability to provide high quality surface treatment of products, high metal consumption, energy consumption.

The technical problem solved by the invention is to obtain high quality surface treatment of products and reducing metal consumption.

The technical result is achieved by the fact that there are unbalances on the drive shaft that can rotate, creating horizontal vibrations to the vibration-smoothing organ of the unit, the possibility of transmitting rotation of the drive shaft allows you to transfer torque to a planetary single-stage gearbox, on the output shaft through a flange connection a smoothing disk is fixed with the ability rotate and oscillate in the horizontal plane.

The invention is illustrated by drawings: figure 1 shows a longitudinal section of a vibrating smoothing installation, figure 2 shows a top view.

The disk smoothing-out device with rectilinear horizontal vibrations consists of a housing 11, a drive shaft 1, driven by an electric motor 10. An unbalance 6, a gear gear 2, which is in contact with the gear gear 3, is mounted on the drive shaft 1. The gear 3 is rigidly connected to the unbalance shaft 4, on which the unbalance is installed 5. The shaft 1 has the ability to transmit torque to a single-stage planetary gearbox 8, which is fixedly mounted on the housing 11, a single-stage planetary gearbox 8 is in contact with yhodnym shaft 9 which through flange connection 12 is secured smoothing disc 7. The housing 11 is secured to frame 14 by a flexible element 15, which allows to make rectilinear oscillations in a horizontal plane. The function of which is a disk smoothing machine that performs rectilinear horizontal vibrations.

The vibration-smoothing installation works as follows: when you turn on the electric motor 10, which is fixedly mounted on the frame 14, which is mounted on the portal, to move the working body in space, through the belt drive 13, the rotation is transmitted to the drive shaft 1, on which the gear 2 is transmitted, which transfers through the gear rotation gear engagement 3 located on the unbalance shaft 4. The unbalance shafts 5, 6 rotate in different directions, which creates horizontal rectilinear vibrations of the vibration-smoothing organ installation. The rotation of the drive shaft 1 transmits torque to the planetary one-stage gearbox 8, therefore, the rotation speed of the output shaft 9 decreases, and the torque on the output shaft 9 of the planetary one-stage gearbox 8 increases. A smoothing disk 7 is fixed to the shaft 9 through a flange connection 12, which rotates about its axis, and also performs linear vibrations along a gear-circular path.

The advantage of this design is the high quality of processing hard concrete mixtures, obtaining the smallest roughness.
