Description

The invention relates to the construction, in particular to the structures of foundations for equipment with dynamic loads.

The purpose of the invention is to increase the efficiency of damping vibrations and reduce the dynamic loads on the lower structure of the foundation.

The drawing shows a damping foundation foundation for equipment, a lateral section pro- cushioning foundation foundation. You can increase the effectiveness of vibration isolation. The damping column is positioned by interfacial absorption by the upper 1 and lower 2 structures of the foundation for equipment. The stand includes a telescopic holder, fixed on the lower supporting structure 2 with a gap relative to the upper 1 building, and the rod 3 placed in it with a hinged fifth 4.

The coil is made of coaxially disposed upper outer 5 and lower inner 6 sections.

At the upper end of the inner section 6, blocks 7 are installed, bending around with cables 8, one ends of which are connected to the outer section 6 of the yoke, which plays the role of inertial mass, and others with the fifth 4, placed in the telescopic yoke between 25 and the lower structure - gin 3 its m. lower end of the hinged soy and covering the cage, which, when the vibration-insulating object moves down or up, the rod 3 interacts with the heel 4, which through the blocks 7 with the help of cables 8 respectively lifts or lowers the outer section 5 about oymi, which plays the role of inertial mass, which creates antiphase quenching of high-frequency oscillations of the object.

low-frequency oscillations of the object and thereby reduce the dynamic loads on the foundation.

Invention Formula Damping rack foundation for equipment, including the holder mounted on the lower structure with a gap relative to the upper structure, and placed in the holder rod, characterized in that, in order to increase the efficiency of damping vibrations and reduce dynamic loads on the upper structure of the foundation, the rack equipped with a spring, separated from point 4, and the upper attached to the upper structure I of the foundation on which the equipment is installed (not shown). The yoke is located inside the spring 9 installed between the lower and upper structures. The shock absorbing strut of the foundation works as follows. thirty The shaft is made of coaxial upper outer and lower inner sections with blocks installed at its upper end, and the rod is made with a hinged pin attached to its lower end, which is connected to the lower part of the upper section of the cage by means of cables that envelop the blocks. When the vibration-insulated object moves down or up, rod 3 interacts with point 4, which, through blocks 7, using cables 8, respectively, raises or lowers the outer section 5 of the holder, which acts as inertial mass, which creates antiphase damping of high-frequency oscillations of the object . due to antiphase quenching low-frequency oscillations of the object and thereby reduce the dynamic loads on the foundation. Invention Formula due to antiphase quenching between the upper and lower structures and encompassing the holder, which you have an amortizing base stand for equipment, including a holder mounted on the lower structure with a gap relative to the upper structure, and placed in the holder, increasing the efficiency of damping vibrations and reducing the dynamic loads on the superstructure of the foundation, the stand is equipped with a spring, The shaft is made of coaxial upper outer and lower inner sections with blocks installed at its upper end, and the rod is made with a hinged pin attached to its lower end, which is connected to the lower part of the upper section of the cage by means of cables that envelop the blocks.
