Background technology

In the railway construction of China; The importance of high-speed railway is increasing; And since quality and the speed of train constantly increase, in the time of in the construction of high-speed railway, just must solving vehicle and move fast the vibration of generation and noise to move and railway roadbed aspect influence, otherwise will shorten greatly its application life; The probability that is broken down also improves greatly; For overcoming firm interference and the infringement with vehicle operating of vibrating noise, the effectively technology and the product of vibration and noise reducing just must be arranged, the safety of moving with the guarantee circuit and reach desirable speed to railway roadbed.

And, in building construction, infrastructure are laid and built, need with it similarly shock absorber and vibration absorber equally.

Prior oscillating damper adopts rubber pad or helical spring sleeve etc. usually, and spring cushion for example shown in Figure 1 is fixed with helical spring in the sleeve, be connected to railway roadbed or other positions behind the top seal of hollow sleeve; Hollow sleeve welds two-layer block, and top is the jacking block, and the bottom is a support limit stop, and helical spring is installed in the sleeve; Stretch out to carry out vibration damping helical spring bottom, and such helical spring shock absorber minimum constructive height is higher, such as accomplishing that compliance is relatively poor more than the 280mm; In a single day jacking block and support limit stop lost efficacy, and be difficult to remedy, and helical steel springs were on-insulated; Need other handicapping damping material, cost is high, and reliability is relatively poor.

For this reason, the designer of the utility model is because above-mentioned defective through concentrating on studies and designing, comprehensively is engaged in for a long time the experience and the achievement of related industry for many years, and research and design goes out a kind of vibration reducing sleeve, to overcome above-mentioned defective.

Summary of the invention

The purpose of the utility model is to provide a kind of vibration reducing sleeve, and it is simple in structure, and it is convenient, easy for installation to make; Need not to weld in addition jacking block and support limit stop on the sleeve, reliability is high, and is not fragile; Prolonged application life, the sleeve height can be done very lowly, and compliance is strong.

For realizing above-mentioned purpose; The utility model discloses a kind of vibration reducing sleeve; This vibration reducing sleeve 1 comprises sleeve body 11, and sleeve body 11 is outward extended with at least two juts 13, and these at least two juts 13 equi-spaced apart are arranged at the circumference of sleeve body 11; The centre position of sleeve body 11 is provided with the supported hole 15 that at least two contour intervals are provided with, and supported hole (15) is inverted L shape or rectangle.

Wherein: the bottom of sleeve body 11 is provided with flange in the bottom 12, and the material of this sleeve body 11 is a nodular cast iron, and sleeve welds after adopting monoblock cast or sheet material die mould.

Wherein: this supported hole 15 is an inverted L shape, each supported hole 15 comprise an end from jut 13 along circumference horizontally extending lateral aperture and from the other end of lateral aperture to the vertical hole that extends below.

Wherein: the top of sleeve body 11 is provided with top flange 16, and is connected in the top blind flange 17 on this top flange 16, and top blind flange 17 adopts insulating composite material.

Wherein: the upper end of sleeve body 11 is provided with the horizontal jacking hole 14 that at least two contour intervals are provided with, each jacking hole 14 from jut 13 along the circumference horizontal-extending.

Through said structure, the utility model has been realized following technique effect:

1, simple in structure, need not weld fixingly, and adopted jacking hole, supported hole and buckle to connect, installation and removal are convenient, and are difficult for coming off;

2, adopt nodular cast iron, avoid getting rusty, increase the service life;

3, top blind flange adopts insulating composite material, avoid and rail between the phenomenon that is short-circuited.

The utility model will further be described in detail through following specific embodiment, and further combine will obtain knowing more and significantly understanding to the explanation of accompanying drawing.

The specific embodiment

Referring to Fig. 2 and Fig. 3, shown the sketch map of first embodiment of the vibration reducing sleeve of the utility model, this vibration reducing sleeve 1 is a hollow cylinder; Sleeve 1 comprises sleeve body 11, and the bottom of sleeve body 11 is provided with flange in the bottom 12, and this flange in the bottom 12 is integrally formed with sleeve body 11 through monoblock cast; Preferably, the material of this sleeve body 11 can adopt nodular cast iron or steel, has avoided the defective of getting rusty thus; Durable shape is better, has prolonged application life.

Sleeve body 11 is outward extended with at least two juts 13; These at least two juts 13 equi-spaced apart are arranged at the circumference of sleeve body 11; Preferably as shown in Figure 2,120 degree are provided with three juts 13 at interval at interval, and the centre position of sleeve body 11 is provided with the supported hole 15 that at least two contour intervals are provided with; The number of this supported hole equates with jut 13; This support holes 15 for inverted L shape and comprise an end from jut 13 along circumference horizontally extending lateral aperture and from the other end of lateral aperture to the vertical hole that extends below, preferably, this supported hole 15 can be rectangle.

Preferably, the upper end of sleeve body 11 is provided with the horizontal jacking hole 14 that at least two contour intervals are provided with, and the number in this horizontal jacking hole 14 equates with jut 13, this jacking hole 14 from jut 13 along the circumference horizontal-extending.

Preferably, the top of sleeve body 11 is provided with top flange 16, and is connected in the top blind flange 17 on this top flange 16; Fixed form can be fixing through bolt 18; Top blind flange 17 adopts insulating composite material, and what traditional shock absorber sleeve cover plate adopted is steel plate, is prone to the problem of being short-circuited.

Referring to Fig. 4, shown second embodiment of the vibration reducing sleeve of the utility model, the circumferencial direction in different with first embodiment is jacking hole 14 is different, other all just the same.

This shows that the advantage of the utility model is:

2, adopt nodular cast iron or steel, avoid getting rusty, increase the service life;

It is obvious that, and above description and record only are to give an example rather than disclosure, application or use in order to limit the utility model.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the utility model does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of implementing the utility model, and the scope of the utility model will comprise any embodiment of the manual that falls into the front and appended claim.
