The heightening and leveling device comprises an inner sleeve, a spring, an outer sleeve, a retainer ring and a liner plate, wherein the inner sleeve is fixed on a substrate through an anchor bolt device; the upper end of the inner sleeve is arranged on the top of the outer sleeve in a rotating manner, and the lower end of the inner sleeve penetrates into the outer sleeve; the spring is arranged inside the outer sleeve and connected with the inner sleeve through an anchoring device; the retainer ring is fixedly buckled between the lower part of the spring and the inner wall of the outer sleeve; the liner plate is arranged between the inner sleeve and the substrate. The spring in the inner sleeve is connected with the inner sleeve through the anchoring device, so that the relative displacement of the spring and the inner sleeve caused by the stress on the spring can be reduced, and the integrality of the vibration isolator can be improved. When the heightening and leveling device is arranged on an uneven floor, the liner plate is arranged between a vibration isolation system and the substrate, the levelness of the vibration isolation system is guaranteed, the threaded connection of the inner and outer sleeves guarantees the height of the vibration isolation system, and the heightening and leveling purpose can be realized.
Description
Technical field
The invention belongs to railway and field of urban rail, relate to a kind of steel spring floating slab and heighten levelling device.
Background technology
Along with the growth of being packed of urban population, the main flow that the advantages such as subway is large with freight volume, speed fast, nothing is blocked up more and more become people's living trip is selected, and bears more and more arduous resident trip transport task.Subway is in Chinese fast development, the rail system meanwhile adapted with subway is also at successive optimization, and steel spring floating slab, as the one of novel track form, has good effectiveness in vibration suppression, significant noise reduction, is therefore widely used in underground railway track.But meanwhile, in the practice of construction process of steel spring floating slab, occur that following problems demand solves:
1. building height tolerance due to the uneven thickness of base concrete cushion or thickness of slab causes vibration isolator and headspace not to match, in order to adapt to factory's Production line of vibration isolator, reduce delivery cycle, improve speed of application, need badly a kind of can adjustable for height vibration isolator to adapt to the vibration isolator requirement for height under different condition.
2. in construction process, because rail profile size is subject to the restriction of boundary lines of roads, vibration isolator is not allowed to be arranged in outside rail under this kind of condition, the reasons such as construction error cause vibration isolator to be arranged on the downside of rail, be unfavorable for that engineering later period maintenance is changed, therefore needing a kind of vibration isolator with overturning or slip resistance analysis function of design badly can make vibration isolator farthest break away from position restriction, and makes system fully meet overturning or slip resistance analysis security requirement.
3. collect and the reaction of field measurement data according to a large amount of real data, at the changeover portion that plate and plate join, the most easily produce and jolt, cause the irregularity of driving, have a strong impact on the driving mood of passenger, and the reason causing changeover portion to produce irregularity is because the changeover portion rigidity of two plate handing-over is different, visibly different sinking displacement is had under the effect receiving external force, form comparatively obvious displacement height poor, therefore need a kind of steel spring floating slab system self-level(l)ing device utilizing stiffness reliability to realize automatic flat-adjustable function badly.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of self-level(l)ing device for steel spring floating slab system, to realize the object improving steel spring versatility, floating plate resistance to capsizing and train operation smoothness.
For achieving the above object, technical scheme provided by the present invention is: a kind of laying floating ballast bed heightens levelling device, and comprise inner sleeve, spring, outer sleeve, back-up ring, backing plate, inner sleeve is fixed in substrate by anchor bolt device; Inner sleeve upper end is rotatably arranged on outer sleeve top, and its lower end is stretched in outer sleeve; Spring is placed in outer sleeve inside, and is connected by anchor device with inner sleeve; Back-up ring is fixed between spring bottom and outer sleeve inwall; Backing plate is arranged between inner sleeve and substrate.
Spring in inner sleeve of the present invention is connected by anchor device with inner sleeve, the relative displacement that minimizing spring stress and inner sleeve produce, and enhances the globality of vibration isolator.By the anchorage effect of substrate bolt, increase the resist torque of steel spring floating slab, improve the resistance to capsizing of floating plate, not only meet some the special construction requirement in engineering construction, facilitate engineering construction maintenance simultaneously.When the above-mentioned vibrating isolation system arranging composition is placed in uneven ground, backing plate is arranged between above-mentioned vibrating isolation system and substrate, ensure that the level of vibrating isolation system, being threaded of inside and outside sleeve ensure that the height of vibrating isolation system, thus achieves the object heightening leveling.
As a further improvement on the present invention, backing plate is wedge shape concrete block, and the lower surface of backing plate is arranged to skewed.Like this, when the ground with certain slope is laid floating ballast bed, razor-edge liner can ensure the level of vibrating isolation system better.
As a further improvement on the present invention, backing plate is provided with pre-embedded bolt, and with screwed hole bottom inner sleeve, inner sleeve and pre-embedded bolt are threaded engagement.A bolt can certainly be fixed bottom inner sleeve, screwed hole be preset by backing plate, plays object inner sleeve being fixed on substrate equally.
Preferably, steel spring outer sleeve has two parts, A cylinder and B cylinder, and A cylinder is placed in above B cylinder, and described A cylinder, B barrel are provided with screw thread, are threaded connection between A cylinder and B cylinder.
Further, 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, and back-up ring is arranged on A cylinder inner tube wall.
Further, 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, and back-up ring is arranged on B cylinder inner tube wall.
