Abstract
The utility model discloses the adjustable for height outer sleeve of a kind of floating ballast bed vibration isolation steel spring.Tradition vibration isolator and on-the-spot headspace do not match, and reduce speed of application.The utility model includes outer sleeve, and outer sleeve is made up of A cylinder, B cylinder two parts, and A cylinder is placed in above B cylinder, and A cylinder, B barrel are provided with screw thread, are threaded connection between A cylinder and B cylinder.During the utility model floating plate system works, the power acted on rail passes to the road bed board be floated on steel spring vibration isolator.After road bed board is stressed, the power be subject to is passed to after redistributing the vibration isolator be fixed on foundation pad under effect of inertia, be delivered to foundation pad by vibration isolator again, carry out tuning, filtering, absorption energy by vibration isolator in the process, reach the object of vibration isolation and damping.Regulate steel spring outer sleeve height by A cylinder screw thread, B cylinder threaded engagement number of turns difference, thus be applicable to the steel spring floating slab of different thickness of slab, improve the versatility of steel spring.
Description
Technical field
The utility model relates to a kind of sleeve, and particularly one is nested with in vibration isolation steel spring outside and adjustable for height sleeve, belongs to light rail insulator manufacturing technology.
Background technology
In order to obtain good environmental degree of comfort, the track structure of existing subway, light rail abandoning tradition gradually, adopts non-fragment orbit more and more.This senior vibration insulating system of steel spring floating slab arises at the historic moment and is widely used.But steel spring floating slab construction adopts cast in situs, there will be various problem in work progress.For example highly make to transport to on-the-spot vibration isolator and headspace does not match because ground is beaten, extend delivery cycle, reduce speed of application.In order to solve this difficult problem, a kind of way removes the ground exceeded, and this method length consuming time affects the duration.Best bet is the height lowering vibration isolator, and therefore designing a kind of adjustable for height steel spring outer sleeve is the problem that industry needs solution badly.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the adjustable for height outer sleeve of a kind of floating ballast bed vibration isolation steel spring, improves the versatility of sleeve and reduces difficulty of construction.
For achieving the above object, the utility model provides following technical scheme: the adjustable for height outer sleeve of a kind of floating ballast bed vibration isolation steel spring, it includes outer sleeve, outer sleeve is made up of A cylinder, B cylinder two parts, A cylinder is placed in above B cylinder, described A cylinder, B barrel are provided with screw thread, are threaded connection between A cylinder and B cylinder.
During the utility model floating plate system works, the power acted on rail passes to the road bed board be floated on steel spring vibration isolator.After road bed board is stressed, the power be subject to is passed to after redistributing the vibration isolator be fixed on foundation pad under effect of inertia, be delivered to foundation pad by vibration isolator again, carry out tuning, filtering, absorption energy by vibration isolator in the process, reach the object of vibration isolation and damping.Regulate steel spring outer sleeve height by the number of turns difference of A cylinder screw thread, B cylinder threaded engagement, thus be applicable to the steel spring floating slab of different thickness of slab, improve the versatility of steel spring.
Further improve as the utility model, A cylinder screw thread is arranged on outer tube wall Lower Half, and B cylinder screw thread is arranged on the inner tube wall first half.
Further improve as the utility model, A cylinder screw thread is arranged on inner tube wall Lower Half, and B cylinder screw thread is arranged on the outer tube wall first half.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
embodiment 1
As shown in Figures 1 to 3, the present embodiment has two parts: A cylinder 1 and B cylinder 2, structure material adopts steel.A cylinder 1 is positioned at above B cylinder 2, and whole outer sleeve height can at h
1-h
2change arbitrarily in mm interval.
Be threaded connection between A cylinder 1 and B cylinder 2.A cylinder 1 is highly that h3 ~ h4mm, A cylinder screw thread 3 is arranged on outer tube wall Lower Half, and from the bottom of cylinder, A cylinder screw thread 3 is highly b.B cylinder 2 is highly that h3 ~ h4mm, B cylinder screw thread 4 is arranged on the inner tube wall first half, and from nozzle, B cylinder screw thread 4 is highly b.
embodiment 2
As shown in figures 4-6, the present embodiment has two parts: A cylinder 1 and B cylinder 2, structure material adopts steel.A cylinder 1 is positioned at above B cylinder 2, and whole outer sleeve height can at h
1-h
2change arbitrarily in mm interval.
Be threaded connection between A cylinder 1 and B cylinder 2.A cylinder 1 is highly that h3 ~ h4mm, A cylinder screw thread 3 is arranged on inner tube wall Lower Half, and from the bottom of cylinder, A cylinder screw thread 3 is highly b.B cylinder 2 is highly that h3 ~ h4mm, B cylinder screw thread 4 is arranged on the outer tube wall first half, and from nozzle, B cylinder screw thread 4 is highly b.
In above two embodiments, A cylinder 1 and B cylinder 2 adopt screw connection structure, also can adopt slidingtype buckle connecting structure common on the market.
Regulate steel spring outer sleeve height by the number of turns difference of A cylinder screw thread 3, the occlusion of B cylinder screw thread 4, thus be applicable to the steel spring floating slab of different thickness of slab, improve the versatility of steel spring.
