Description

Elastic supporting structure

Technical Field

The utility model relates to the technical field of wind power equipment, in particular to an elastic supporting structure.

Background

As a common damping component, chinese utility model CN200620049857.3 discloses an elastic support for a wind turbine, which cannot bear the upward pulling force generated by the vibration of the equipment during the use, and therefore, the application range of the equipment is limited.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a resilient support structure that solves the problems set forth above in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an elastic support structure, includes adjusting nut, install the swivel nut in the adjusting nut, the swivel nut below is provided with the backup pad, be provided with metal rubber conical spring in the last backup pad, be provided with the bottom suspension fagging in the metal rubber conical spring, be provided with the equipment bolt in the shown bottom suspension fagging, the swivel nut is installed to the other end of equipment bolt.

Preferably, the assembling bolt is internally provided with a through hollow core.

Preferably, a rubber pad (not shown) is disposed between the assembly bolt and the lower support plate.

Compared with the prior art, the utility model provides an elastic supporting structure. The method has the following beneficial effects:

according to the elastic supporting structure, the upper supporting plate is matched with the assembling bolt to compress the metal rubber conical spring in advance, so that the metal rubber conical spring generates certain elastic deformation, the situation that the equipment can fluctuate up and down greatly due to the fact that the metal rubber conical spring generates large elastic deformation due to the force generated by vibration in the using process of the equipment is effectively avoided, or the elastic supporting cannot play a supporting role due to the fact that the metal rubber conical spring generates large deformation, meanwhile, the structure of the assembling bolt is changed, when tensile load occurs, the assembling bolt with the conical surface can transmit the load to the lower supporting plate, the structure is simple, and the tensile effect of the elastic supporting is achieved; the elastic support structure can bear pressure and tensile force, and improves the adaptability and the service life of the elastic support.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides an elastic support structure, includes adjusting nut 1, install swivel nut 2 in the adjusting nut 1, swivel nut 2 below is provided with backup pad 3, upward be provided with metal rubber conical spring 4 in the backup pad 3, this elastic support is exactly that the elastic deformation who utilizes metal rubber conical spring 4 buffers the pressure that constantly shakes the change, be provided with bottom suspension fagging 6 in the metal rubber conical spring 4, be provided with assembly bolt 5 in the shown bottom suspension fagging 6, swivel nut 2 is installed to assembly bolt 5's the other end.

Because the vibration of the equipment can generate tension-compression crossed stress on the elastic support, in order to reduce the internal stress of the assembly bolt 5 and improve the fatigue resistance of the assembly bolt 5 and prevent the assembly bolt 5 from generating fatigue fracture, the inside of the assembly bolt 5 is a through hollow core.

In order to cushion the elastic support when it is subjected to a tensile stress, when the assembly bolts 5 transmit the tensile stress to the lower support plate 6, a rubber pad (not shown) is disposed between the assembly bolts 5 and the lower support plate 6.

The working principle is as follows: when the elastic support is used, the screw sleeve 2 is driven to move by adjusting the assembling bolt 5, the upper support plate 3 is continuously compressed, so that the metal rubber conical spring 4 is compressed to generate certain pre-pressure, the lower support plate 6 is fixedly arranged on a working surface after the required pre-pressure is reached, the equipment is connected with the upper support plate 3, the installation error between the equipment and the upper support plate 3 can be adapted through the position of the adjusting nut 1 on the screw sleeve 2, after the installation is completed, when the equipment runs to generate vibration lower pressure, the upper support plate 3 and the screw sleeve 2 act on the metal rubber conical spring 4, the vibration lower pressure is buffered under the elastic deformation action of the metal rubber conical spring 4, when the equipment runs to generate vibration upper pulling force, the upper support plate 2 drives the assembling bolt 5 to pull up, and the assembling bolt 5 with the conical surface can transmit load to the lower support plate 6, and the phenomenon that the elastic support is damaged or even the elastic support is arranged due to large displacement generated under the action of the vibration upper pulling force is prevented Ready for damage.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. The term "comprising", without further limitation, means that the element so defined is not excluded from the group consisting of additional identical elements in the process, method, article, or apparatus that comprises the element.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
