Whole vibration isolation frame of isolator is arranged to ring

Technical Field

The utility model relates to a frame, in particular to an integral vibration isolation frame of an annularly-arranged vibration isolator.

Background

Vibration isolators are elastomeric elements that connect equipment to a foundation to reduce and eliminate vibrational forces transmitted by the equipment to the foundation and vibrations transmitted by the foundation to the equipment. According to the traditional mode, the vibration isolator is usually arranged on an installation machine leg of power electromechanical equipment such as a steam turbine, a motor, a generator or a speed reducer, but under the environmental conditions of large swing and transverse impact existing on an ocean platform, a ship and the like, the problems of equipment inclination, vibration isolator damage, equipment centering damage, vibration isolation effect reduction and the like are often caused due to insufficient lateral rigidity of vibration isolation.

Disclosure of Invention

The utility model provides an integral vibration isolation frame of annularly arranged vibration isolators, which can ensure that the vibration isolation effect is not reduced in a swinging environment, greatly reduce the centering damage of equipment, avoid the damage of the vibration isolators under the impact condition and ensure the safe and stable operation of the equipment.

The purpose of the utility model is realized as follows: the vibration isolation device comprises a whole frame, a ring-shaped support and cylindrical vibration isolators, wherein the two groups of cylindrical vibration isolators are respectively fixed on the corresponding ring-shaped supports to form a front ring-shaped vibration isolation support and a rear ring-shaped vibration isolation support, the front ring-shaped vibration isolation support and the rear ring-shaped vibration isolation support are fixed on the front vibration isolation support and the rear ring-shaped vibration isolation support in a sleeved mode, the front vibration isolation support and the rear vibration isolation support are fixed in a corresponding groove of the whole frame together with an equipment embedding sleeve, and the whole vibration isolation frame is arranged on a foundation or a base in a rigid or elastic mode.

Furthermore, when the foundation or the base swings, the load of the equipment is pressed and loaded on the circular vibration isolators at different circumferential positions but with consistent performance parameters, so that the supporting rigidity and the vibration isolation effect of the whole vibration isolation frame provided for the equipment by the equipment under the swinging condition are consistent; when equipment bears impact load, resultant force formed by the impact load and the equipment running load is borne by the vibration isolators in the corresponding directions, and is not borne by tangential deformation of the specific vibration isolators, so that the vibration isolators are prevented from being damaged.

Compared with the prior art, the utility model has the beneficial effects that: according to the running state and running requirements of power electromechanical equipment in a swinging and impacting environment, the overall vibration isolation frame of the annularly-arranged vibration isolator is designed, the overall vibration isolation frame can provide the same or similar supporting rigidity in all radial directions for the equipment, the vibration isolation effect can be ensured not to be reduced in the swinging environment, the centering damage of the equipment can be greatly reduced under the impacting condition, the damage of the vibration isolator is avoided, and the safe and stable running of the equipment is ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The integral vibration isolation frame of the annularly-arranged vibration isolator consists of an integral frame 1, an annular bracket 2 and a cylindrical vibration isolator 3. Cylindrical vibration isolator 3 is according to the operation rotational speed of power electromechanical device, the operation load, operation environment and isolator arrange that quantity isoparametric select out the cylindrical vibration isolator who satisfies equipment operation and vibration isolation requirement, be fixed in cylindrical vibration isolator 3 and form annular vibration isolation support on ring carrier 2, be fixed in preceding with the equipment suit, on two back vibration isolation supports, again with preceding, two back vibration isolation support vibration isolation supports together with equipment inlay the cover and fix to corresponding recess of whole frame 1 in, whole vibration isolation frame rigidity or elastic arranging on basis or base. When the foundation or the base swings, the load of the equipment can be ballasted on the circular vibration isolators with different circumferential positions but basically consistent performance parameters, so that the supporting rigidity and the vibration isolation effect provided by the whole vibration isolation frame for the equipment are basically consistent under the swinging condition of the equipment; when the equipment bears the impact load, the resultant force formed by the impact load and the equipment running load can be borne by the vibration isolators in the corresponding directions instead of the specific vibration isolators through tangential deformation, so that the damage of the vibration isolators is avoided; meanwhile, the whole vibration isolation frame of the annularly-arranged vibration isolator can provide basically consistent supporting rigidity in all directions for equipment, so that the centering damage of the equipment under the conditions of impact and swing of the equipment is greatly reduced compared with the prior art.

The utility model provides an integral vibration isolation frame of annularly arranged vibration isolators, which is characterized in that equipment is sleeved and fixed on an integral vibration isolation system formed by vibration isolation supports of a front annularly arranged vibration isolator and a rear annularly arranged vibration isolator to reduce and eliminate vibration force transmitted to a foundation by the equipment and vibration transmitted to the equipment by the foundation, and meanwhile, the annular vibration isolation supports are used for reducing and eliminating vibration force transmitted to the foundation by the equipment and vibration transmitted to the equipment by the foundation

The same or similar supporting rigidity in all radial directions is provided for equipment, the front and rear vibration isolation supports are embedded and fixed into the integral frame in order to achieve normal installation of the equipment, and the front and rear vibration isolation supports are rigidly or elastically installed on a foundation or a base frame through the installation surface of the integral frame.
