Description
Technical field
This utility model belongs to noise reduction technology field peculiar to vessel, particularly to a kind of stop.
Background technology
For naval vessel electromechanical equipment vibration and noise reducing engineering, generally use vibrating isolation system to carry out xegregating unit and pass to the vibration of pedestal
Pass, and absorb the energy that impact is brought.In order to limiting device is excessive by producing dynamic respond during external impact load, exceedes and set
Standby and the maximum distortion of damping element, it is necessary for now install stop in vibrating isolation system carrying out the displacement of limiting device
's.
Summary of the invention
The purpose of this utility model is: when vibrating isolation system is impacted, it is provided that a kind of variable rigidity stop, stop
Rigidity increases with the increase of displacement, to reach the purpose of protection equipment.
The technical solution of the utility model is: a kind of variable rigidity adjusts casing stop, and it includes: by upper installation panel,
Body structure that lower installation panel and two blocks of side plates are constituted and the limit assembly of variation rigidity；
The limit assembly of variation rigidity includes: two pieces of swash plates in X-type cross, first-level buffer spring, level 2 buffering spring with
And rigid support post；
Panel is installed on connecting in the upper surface of two pieces of swash plates, and lower surface respectively connects one block of side plate；The two of first-level buffer spring
End connects two blocks of side plates respectively；Level 2 buffering spring and rigid support post are arranged in the lower installation panel between two blocks of side plates
On, the height of rigid support post is less than the height of level 2 buffering spring；
On lower installation panel, the elastic deformation direction along first-level buffer spring is provided with spacing slideway；Two blocks of side plates can be along limit
Position slideway moves.
During utility model works, upper installation panel is connected with equipment, and lower installation panel is connected with pedestal.When equipment is subject to
During impact loading, two pieces of swash plates in X-type cross move downward two blocks of side plates of drive in orbit to two lateral movements.Work as punching
Hit displacement less time, two blocks of side plates are resetted by first-level buffer spring works；Along with the increasing of displacement, level 2 buffering spring starts work
Bottom as two pieces of swash plates provides support, until last rigid support work, rigidity drastically strengthens, it is achieved that variation rigidity, reaches
Purpose to apparatus with shock absorbing.
Beneficial effect: 1. this utility model provide a kind of rigidity adjustable limiting device, be equipped with and buffer spring, two grades delay
Rush spring and rigid support, it is achieved that the adjustable purpose of rigidity.
2. this utility model compact conformation, easy installation and removal, improves workman's construction, the convenience of maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural representation of two pieces of swash plates.
Detailed description of the invention
Seeing accompanying drawing, a kind of rigidity adjustable casing stop, it includes: by the upper installation panel 1 be arrangeding in parallel, lower installation
Panel 9, it is vertically set on the limit of the limit assembly of casing that two blocks of side plates 4 of lower installation panel 9 both sides constitute and variation rigidity
Hyte part；
The adjustable limit assembly of rigidity includes: two pieces of swash plates 3 in X-type cross, first-level buffer spring 6, level 2 buffering bullet
Spring 7 and rigid support post 8；
Lower installation panel 9 is provided with horizontal spacing slideway 5；The bottom of two blocks of side plates 4 is provided with slide block, at the work of slide block
Under with, side plate 4 can transverse shifting in spacing slideway 5；
The upper surface of two pieces of swash plates 3 connects the upper installation panel 1 of horizontal positioned, and lower surface respectively connects one block of side plate 4；One-level
The two ends of buffer spring 6 connect two blocks of side plates 4 respectively；Four level 2 buffering springs 7 and two rigid support posts 8 are vertically arranged
On lower installation panel 9 between two blocks of side plates 4, wherein each two level 2 buffering spring 7 and a rigid support post 8 are spaced cloth
Putting one group of two grades of support component of formation, two groups of two grades of support components are arranged in both sides before and after first-level buffer spring 6.Rigidity
The height of support column 8 is less than the height of level 2 buffering spring 7；
When upper installation panel 1 is by downward impact, two pieces of swash plates 3 produce downward displacement, and drive two blocks of side plates 4
Along spacing slideway 5 respectively to two side shiftings；When impacting displacement and being less, only first-level buffer spring 6 provides spring tension, by two pieces
Side plate 4 resets；Along with the increasing of displacement, level 2 buffering spring 7 is started working and is provided resilient support into two pieces of swash plates 3, until
Rear rigid support 8 works.
Further, for strengthening the protection to limit assembly, lower installation panel 9 being additionally provided with two pieces of risers, two pieces are erected
First-level buffer spring 6, level 2 buffering spring 7 and rigid support post 8 are surrounded by plate and two blocks of side plates 4.
