Abstract

The invention belongs to the technical field of marine vibration and noise reduction, and particularly relates to a limiting stopper. The variable-rigidity box limiting stopper comprises a box structure formed by an upper installation panel, a lower installation panel and two side panels, and a variable-rigidity limiting component. According to the technical scheme, the upper installation panel is connected with equipment, and the lower installation panel is connected with a base. When the equipment is subjected to an impulse load, two oblique plates crossing into an X shape move downwards to drive the two side panels to move on a track towards two sides. When impact displacement is small, a primary buffer spring works to restore the two side panels; as displacement increases, a secondary buffer spring starts to work to support the bottom portions of the two oblique plates till rigid support is achieved, variable rigidity is realized as rigidity increases rapidly, and then impact energy is absorbed. The variable-rigidity box limiting stopper is compact in structure and convenient to install and detach, and construction and maintenance convenience is improved.

Description

A kind of variable rigidity casing stop
Technical field
The invention 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 transmit to the vibration of pedestal, and Absorb the energy that impact is brought.In order to limiting device is excessive by producing dynamic respond during external impact load, exceedes equipment and subtract Shake the maximum distortion of element, and it is necessary for now install stop in vibrating isolation system carrying out the displacement of limiting device.
Summary of the invention
It is an object of the invention to: when vibrating isolation system is impacted, it is provided that a kind of variable rigidity stop, stop rigidity is with position Move increase and increase, to reach the purpose of protection equipment.
The technical scheme is that a kind of variable rigidity adjusts casing stop, it includes: by upper installation panel, lower installed surface Body structure that plate 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 and just Property support column;
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 ends of first-level buffer spring are respectively Connect two blocks of side plates;Level 2 buffering spring and rigid support post are arranged on the lower installation panel between two blocks of side plates, and rigidity is propped up The height of dagger 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 spacing slideway Mobile.
When the present invention works, upper installation panel is connected with equipment, and lower installation panel is connected with pedestal.When equipment is by shock loading During effect, two pieces of swash plates in X-type cross move downward two blocks of side plates of drive in orbit to two lateral movements.When impacting displacement relatively Hour, two blocks of side plates are resetted by first-level buffer spring works;Along with the increasing of displacement, it is two pieces that level 2 buffering spring is started working The bottom of swash plate provides and supports, until last rigid support work, rigidity drastically strengthens, it is achieved that variation rigidity, reaches to absorb punching Hit the purpose of energy.
Beneficial effect: 1. the present invention provide a kind of rigidity adjustable limiting device, be equipped with and buffer spring, level 2 buffering spring and Rigid support, it is achieved that the adjustable purpose of rigidity.
2. present configuration is compact, easy installation and removal, improves workman's construction, the convenience of maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
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 installed surface Plate 9, it is vertically set on limit assembly spacing of casing that two blocks of side plates 4 of lower installation panel 9 both sides constitute and variation rigidity Assembly;
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 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, in the effect of slide block Under, 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;First-level buffer The two ends of spring 6 connect two blocks of side plates 4 respectively;Four level 2 buffering springs 7 and two rigid support posts 8 are arranged vertically at 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 pieces of side plate 4 edges Spacing slideway 5 is 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 Last rigid support 8 works.
Further, for strengthening protection to limit assembly, lower installation panel 9 is additionally provided with two pieces of risers, two pieces of risers with First-level buffer spring 6, level 2 buffering spring 7 and rigid support post 8 are surrounded by two blocks of side plates 4.
