SU1641960A1 - Internal vibrator - Google Patents

Abstract

The invention relates to vibration technology and can be used in construction, for example, to compact concrete. The aim of the invention is the expansion of operational capabilities through the use of hard-to-reach places with small dimensions. Deep vibratory compactor includes a housing 1 with a vibration exciter located in it, having, for example, a pneumatic drive. On the housing 1 fixed strip 3 with ribs 4 and Windows 5, vlad-. the role of the working body. The installation of rigid strips 3 on the housing at an angle to the vertical plane and the location of the ribs 4 above or below the windows 5 at angles to the rigid strips 3 when the latter are immersed in a working environment, such as a concrete mass, allows for spatial fluctuations. 1 hp ff, 10 ill.

Claims (2)

Claim 1. Depth vibration damper comprising a housing with a cylindrical cavity and ribs acting as a working body, located in the cavity and connected to the housing by a vibration exciter and a drive connected to the latter, characterized in that, in order to expand operational capabilities, the ribs are connected to the housing through hard strip having windows. 2. The vibration seal according to claim 1, which excludes the fact that the vibration exciter is made in the form of an axis placed in the cavity and a rotor with a central hole mounted with a radial clearance on the axis, having a semicircular through recess and radial protrusions, the step of which in the place of rasA-A of the position of the through semicircular recess is reduced.
