SU759654A1 - Vibration-insulated foundation for equipment - Google Patents

Description

The invention relates to the field of accessibility to the individual vibro-living industry, namely to the foundations for equipment with dynamic loads.

The well-insulated foundation for a turbine unit is known, including a beam top plate and support frames.

m ·

The disadvantage of the known foundation are poor vibration insulation properties.

The closest technical solution to the invention is a vibration-insulated foundation for equipment, including the top plate, supported by means of vibration insulators on vertical supports (£ 2).

The disadvantage of this foundation is the need to build bulky capitals on racks to accommodate vibration isolators. In addition, with a large number of vibration insulators, their maintenance and replacement is hampered due to limited or unavailable

lecturers. .

The aim of the invention is to simplify the structure of the foundation and facilitate the conditions of its operation.

This goal is achieved due to the fact that in a known vibroisolated foundation, including the upper plate, supported by means of vibro-

¹⁰ insulators on vertical racks, the latter are made with consoles, and the Top plate is equipped with vertical frames adjacent to its lower surface, each of which has a horizon ^{, 5} tal struts, the vibration isolators being placed on the consoles of the vertical racks, each frame is supported on vibration isolators, and vibroiopa _Λ tori can be equipped with regulating devices.

FIG. 1 shows the foundation ^ general view; in fig. 2 - section А ^ А in FIG. one; in fig. 3 is a section BB in FIG. one.

The foundation includes an upper plate 1, fitted with 2 vertical frames 3 adjacent to its lower surface, which are supported by vibration isolators 4 placed on the consoles 5 vertical stands on the stands 6. The vibration isolators 4 can be placed along two or four edges along the height of the stands 6 racks 6. '

The frame 3 can be performed as lattice with vertical and horizontal (spacers) elements 7, and a cantilever structure.

Each vibration absorber 4 or a group of vibration isolators can be equipped with regulating devices, such as screw or hydraulic jacks, which facilitate their installation, loading and replacement during operation. If the columns are hollow, then inside them can be placed dampers 8 visyogb or dry treyya.

The work of the foundation are carried out as follows. '‘'

The load from the equipment through the top plate 1 and the vertical frames 3 is transmitted to vibration insulators 4, which, damping it, transmit the Operating forces further through the arms 5 to the racks θ.

In the described foundation, access to each vibration isolator is facilitated, a large number of vibration insulators are placed in a relatively small area and in places convenient from the point of view of equipment layout and maintenance. The absence of vibration isolators At the upper ends of the columns allows, in addition to

In addition, it is difficult to make the columns hollow and place dampers inside them.

Claims (1)

Claim 1. Vibro-insulated foundation U under the equipment, including the upper the plate supported by vibration insulators on vertical posts is distinguished by the fact that, in order to simplify the design of the foundation and about ₁₅ light conditions for its operation, the vertical posts are made with consoles, and the upper plate is provided with vertical frames adjacent to its bottom surface, each of which 20 has horizontal struts, the vibration isolators being placed on the consoles of the vertical supports, and each frame is supported on the vibration isolators by means of struts. · _To 25 2. Vibro-isolated foundation by π. 1, that is, the vibration insulators are equipped with regulating devices.
