Abstract
A height adjustable vibration reduction outer sleeve comprises a cover plate, an upper sleeve and a lower sleeve. The sleeve wall of the hollow upper sleeve decreases gradually along with the increase of the height, and a taper is formed on the external surface of the upper sleeve; the cover plate in a round disk shape is arranged at the top of the upper sleeve and seals the upper opening of the upper sleeve; the hollow lower sleeve is provided with a round ring at the bottom end, the round ring extends upwards to form a boss which extends upwards to form a meshing flange, and an external thread is arranged on the external circumference of the meshing flange; and an internal thread meshed with the external thread is arranged on the internal circumference of the lower sleeve wall of the upper sleeve, and the meshing flange protrudes into and is fixedly meshed with the lower sleeve wall of the upper sleeve. The outer sleeve provided with an adjustable height is simple in structure, convenient to use, capable of reducing vibration effectively and wide in applications.
Description
Technical field
The present invention relates to the technical field of steel rail vibration damping, relate in particular to a kind of height-adjustable vibration damping outer sleeve.
Background technology
In recent years, along with the develop rapidly of China's track traffic, track traffic progressively enters into our life.Track traffic is when providing quick, comfortable, safe trip to us, the vibration of its generation and noise problem also serious impact periphery resident's life quality of life, jeopardize the safety of neighboring buildings, meanwhile, also will be affected in the stability of track traffic itself, safety and application life.Therefore, the harm bringing in order to alleviate vibration that track traffic brings and noise problem, just must have effectively technology and the product of vibration and noise reducing, makes the people that serve that track traffic can follow.
Vibration and the noise problem in order effectively to solve track traffic, brought, applicant is through long-term research and test, work out a kind of height-adjustable vibration damping outer sleeve, can be applicable to ballastless track structure, and there is good effectiveness in vibration suppression, the height of whole vibration damping outer sleeve can regulate simultaneously, to overcome above-mentioned defect.
Summary of the invention
The object of the present invention is to provide a kind of height-adjustable vibration damping outer sleeve, it is simple in structure, easy to use, can carry out effective vibration damping, and highly adjustable, applicable more extensive.
For achieving the above object, the invention discloses a kind of height-adjustable vibration damping outer sleeve, comprise cover plate, upper bush and lower sleeve, it is characterized in that:
This upper bush is hollow sleeve, and its barrel is with highly increasing and reduce gradually, at the external surface formation tapering of this upper bush;
This cover plate is arranged at top and its upper shed of capping of this upper bush, and this cover plate is discoid;
This lower sleeve is hollow sleeve, and its bottom is provided with annulus, and annulus extends upward a boss, and an engagement flange is extended in boss top, and the excircle of this engagement flange is provided with external screw thread;
The inner periphery of the lower end barrel of described upper bush is provided with the internal thread with the engagement of described external screw thread, and this engagement flange stretches in the lower end barrel of this upper bush and is engaged with fixing.
Wherein: this upper bush and lower sleeve are made by steel material, and surface do zinc-plated processing to form zinc coat.
Wherein: this cover plate is made by rubber.
Wherein: height-adjustable outer sleeve height is between 150mm-800mm, and maximum outside diameter is between 200mm-600mm.
By said structure, height-adjustable vibration damping outer sleeve of the present invention.
The present invention will be further described in detail by the following specific embodiments, and will be more apparent and obvious to understand further combined with the description of the drawings.
Accompanying drawing explanation
Fig. 1 is the decomposing schematic representation of height-adjustable vibration damping outer sleeve of the present invention.
Fig. 2 is the sectional view of height-adjustable vibration damping outer sleeve of the present invention.
The specific embodiment
Refer to shown in Fig. 1, height-adjustable vibration damping outer sleeve of the present invention comprises cover plate 1, upper bush 2 and lower sleeve 3.
This upper bush 2 is hollow sleeve, and its barrel is with highly increasing and reduce gradually, and at the external surface formation tapering of this upper bush, it is made by steel material, and zinc-plated processing is done to form zinc coat in surface.
Described cover plate 1 is arranged at top and its upper shed of capping of this upper bush 2, and this cover plate is discoid, and it is made by rubber, in protection internal construction, has good insulating effect.
This lower sleeve 3 is hollow sleeve, and its bottom is provided with annulus, and annulus extends upward a boss, an engagement flange is extended in boss top, the excircle of this engagement flange is provided with external screw thread, and this lower sleeve 3 is made by steel material, and zinc-plated processing is done to form zinc coat in surface.
The inner periphery of the lower end barrel of described upper bush 2 is provided with the internal thread with described external screw thread engagement, thus, this engagement flange can stretch in the lower end barrel of this upper bush 2 and be engaged with fixing (referring to Fig. 2), thus, upper bush 2 and lower sleeve 3 interconnect by screw thread, and the screw thread of engagement has the effect of heightening concurrently simultaneously, by heightening this design of screw thread, the height of this vibration damping outer sleeve can be through a certain amount of adjusting of row, thereby the unnecessary trouble of having avoided to a great extent substrate construction error to bring, has facilitated the carrying out of constructing.
Preferably, whole height-adjustable outer sleeve height is a(a value between 150mm-800mm), maximum outside diameter is b(b value between 200mm-600mm).
In the present invention, cover plate 1 is made by the rubber with effectiveness in vibration suppression, can make whole outer sleeve have effectiveness in vibration suppression when supporting, and the design of the disk of cover plate, and its shock attenuation result is more all horizontal; And the engagement system of upper and lower sleeve is special, has adopted and has been threaded, not only stable connection, has more height-adjustable effect, can be applicable to different altitude ranges, has facilitated and has used and construct.
It is evident that above description and to record be only for example rather than in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the present invention does not limit by accompanying drawing example and the conduct of describing is in an embodiment thought to be at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of the manual that falls into above and appended claim.
