Description

浮置道床 技术领域  Floating track bed
本发明属于铁路道床， 尤其是涉及一种铁路的轨道结构， 具体可以是 铁路、 地铁、 城市铁路、 高架轻轨、 高速铁路等。 背景技术  The invention belongs to a railway track bed, and particularly relates to a railway track structure, which may specifically be a railway, a subway, a city railway, an elevated light rail, a high speed railway, and the like. Background technique
传统的铁路或城市铁路轨道结构， 当线路与地面建筑物的距离较近时， 会对其产生较大的振动和噪声影响。 振动和和噪声主要由于轮轨的不平顺 和相对运动产生，其中噪声通过空气介质传播到建筑物中（称为一次噪声）， 而振动则通过轨道 -道床 -隧道壁 -地基， 或者轨道 -道床 -桥梁一桥墩 -地基传到建筑物上， 再通过建筑结构本身的耦合放大而激发出楼板的低 频振动， 振动源中没有衰减掉的高频成分则通过墙壁、 地板和天花板发出 的二次噪声。 这种振动和噪声都会对人构成不良影响。  Traditional railway or urban railway track structures, when the distance between the line and the ground building is relatively close, will have a large vibration and noise impact. Vibration and noise are mainly caused by the irregularity and relative motion of the wheel and rail, where the noise propagates through the air medium into the building (called a primary noise), and the vibration passes through the track-track bed-tunnel wall-foundation, or track-track bed - Bridges, piers and foundations are transmitted to the building, and then the low-frequency vibration of the floor is excited by the coupling amplification of the building structure itself. The high-frequency components that are not attenuated in the vibration source are secondary noise emitted through the walls, floors and ceilings. . This vibration and noise can have an adverse effect on people.
才 据上述认识， 世界各国陆续开发出了各式各样的减振降噪措施， 例 如用隔声屏来吸收隔离一次噪音， 用各式各样弹性扣件和道床型式来控制 振动和二次噪声， 比较著名的例如有科隆蛋和弹性套靴。  According to the above understanding, various countries in the world have developed a variety of vibration and noise reduction measures, such as the use of sound insulation screen to absorb the isolation of the primary noise, with a variety of elastic fasteners and track bed type to control vibration and secondary Noise, more famous, such as Cologne eggs and elastic boots.
科隆蛋和弹性套靴可以满足 5-8分贝的低档减振要求（指***损失， 下同）， 但科隆蛋的横向刚度较低， 不适于曲线段； 如橡胶工艺或材盾不好 还会造成橡胶圈脱落， 影响行车安全； 弹性套靴容易进水和灰尘， 不易检 修更换。  Cologne eggs and elastic boots can meet the low-end damping requirements of 5-8 decibels (referring to the insertion loss, the same below), but the Cologne eggs have lower lateral stiffness and are not suitable for curved sections; if the rubber process or material shield is not good The rubber ring is detached, which affects the safety of driving. The elastic boots are easy to enter the water and dust, and are difficult to repair and replace.
橡胶浮置板可以满足 8-15分贝的中档减振要求，一般由浮置板和橡胶 支承块或叠层钢板橡胶支承块组成， 浮置板通常由混凝土预制而成， 长度 较短。 橡胶浮置板具有如下缺点: _ 橡胶支承块或叠层钢板橡胶支承块各向 刚度相互制约， 横向刚度低， 不能满足道床的横向稳定性要求， 因此除垂 向支承的橡胶支承块外， 还需横向支承的橡胶支承块， 结构复杂； 橡胶支 承块隐藏于浮置板下面， 很难调平、 检修和更换， 尤其是无法从浮置道床 侧面或顶面检修； 浮置板长度有限， 容易发生共振， 加上橡胶本身阻尼太 小， 不能吸收浮置板的振动能量， 致使浮置板振动加大， 橡胶浮置板隔振 地段车内振动和噪声明显提高， 钢轨摩擦加剧； 橡胶对材料和工艺要求高， 易老化， 寿命有限， 更换橡胶支承块对列车运营和市民的出行影响较大。 对于更高的减振要求， 即减振效果 15分贝 _40分贝之间的高档减振要 求， 橡胶浮置板或技术上难以实现， 或经济性较差。 发明内容 The rubber floating plate can meet the mid-range vibration damping requirement of 8-15 decibels. It is generally composed of a floating plate and a rubber support block or a laminated steel rubber support block. The floating plate is usually prefabricated from concrete and has a short length. The rubber floating plate has the following disadvantages: _ The rubber bearing block or the laminated steel plate rubber support block has mutual stiffness constraints, low lateral stiffness, and cannot meet the lateral stability requirements of the track bed, so in addition to the vertically supported rubber support block, The rubber support block that needs to be laterally supported has a complicated structure; the rubber support block is hidden under the floating plate, which is difficult to level, repair and replace, especially in the side or top surface of the floating track bed; the floating plate has a limited length and is easy to Resonance occurs, and the damping of the rubber itself is too small to absorb the vibration energy of the floating plate, which causes the vibration of the floating plate to increase. The vibration and noise in the vibration isolation section of the rubber floating plate are obviously improved, and the friction of the rail is intensified; And high process requirements, It is easy to age and has a limited life. The replacement of rubber support blocks has a great impact on train operation and public travel. For higher vibration reduction requirements, that is, the high-level vibration reduction requirement between 15 decibels and _40 decibels, the rubber floating plate is technically difficult to achieve, or economically poor. Summary of the invention
为了克服上述缺陷， 满足中高档的减振要求， 本发明提出了一种新的 浮置道床***。  In order to overcome the above drawbacks and to meet the medium and high-grade vibration damping requirements, the present invention proposes a new floating track bed system.
本发明的浮置道床***包括浮置板和弹簧隔振器， 浮置板弹性地支承 于弹簧隔振器上。  The floating track bed system of the present invention includes a floating plate and a spring isolator that is resiliently supported on the spring isolator.
所述弹簧隔振器基本由弹簧和弹簧壳体构成，弹簧与弹簧壳体相联接， 形成一个部件， 从而便于运输、 安装及与浮置板联接； 弹簧为螺旋弹簧、 碟簧或者橡胶金属复合弹簧。 所述弹簧弹性高， 可以在很宽的弹性范围内 设计选择， 且横向刚度经过设计均能满足道床横向稳定性的要求， 无需额 外的横向支承， 结构筒单， 这是本发明所述弹簧隔振器与现有橡胶浮置板 所用的橡胶支承块或叠层钢板橡胶支承块的重要区别之一。  The spring isolator is basically composed of a spring and a spring housing, and the spring is coupled with the spring housing to form a component, which is convenient for transportation, installation and connection with the floating plate; the spring is a coil spring, a disc spring or a rubber metal composite spring. The spring has high elasticity, can be designed and selected in a wide elastic range, and the lateral stiffness is designed to meet the requirements of the lateral stability of the track bed, without additional lateral support, and the structure is simple, which is the spring partition of the present invention. One of the important differences between the vibrator and the rubber support block or laminated steel rubber support block used in the existing rubber floating plate.
为了增强道床***或浮置板本身的阻尼， 抑制共振， 减少浮置板本身 的振动和噪声， 在浮置板上设置阻尼元件或阻尼结构。  In order to enhance the damping of the track bed system or the floating plate itself, suppress the resonance, and reduce the vibration and noise of the floating plate itself, a damping element or a damping structure is provided on the floating plate.
在浮置板上单独设置阻尼元件需要额外的空间， 还需单独固定， 为了 节省空间， 简化结构布置， 弹簧隔振器上还可以集成有阻尼， 具体实现方 式为： 其一， 弹簧隔振器的弹簧壳体带有密封结构， 壳体内设有液体阻尼， 弹簧下部浸在液体阻尼中； 其二， 弹簧丝的至少部分表面设有约束阻尼， 或者弹簧的至少局部嵌入固体阻尼材料之中。  Separately setting the damping element on the floating plate requires additional space and needs to be separately fixed. In order to save space and simplify the structural arrangement, the spring isolator can also be integrated with damping. The specific implementation is as follows: First, the spring isolator The spring housing has a sealing structure, the housing is provided with liquid damping, and the lower part of the spring is immersed in the liquid damping; secondly, at least part of the surface of the spring wire is provided with constrained damping, or at least partially embedded in the solid damping material.
弹簧隔振器与浮置板的位置关系至少可以有两种： 一种是弹簧隔振器 设置在浮置板的下方， 支承在浮置板的外侧底面上， 可称之为外置式； 另 一种是弹簧隔振器设置在浮置板的预留通孔内， 通孔的内壁上设置支承挡 块， 浮置板通过支承挡块支承于弹簧隔振器上， 可称之为内置式。  There are at least two kinds of positional relationship between the spring isolator and the floating plate: one is that the spring isolator is disposed under the floating plate and supported on the outer bottom surface of the floating plate, which can be called an external type; One is that the spring isolator is disposed in the reserved through hole of the floating plate, and the inner wall of the through hole is provided with a support block, and the floating plate is supported by the spring isolator through the support block, which can be called built-in type .
支承挡块可以是浮置板预留通孔内壁上的混凝土构造， 也可以是嵌入 混凝土的金属预埋件， 或者浮置板的通孔内嵌有联结套筒， 再在联结套筒 内壁上设置支承挡块， 其中支承挡块可以预先与联结套筒焊接在一起， 然 后联结套筒与浮置板浇注成一体； 支承挡块也可以是一个整体的挡环。 为了能够从浮置板上方顶升浮置板并调整浮置板的高度和水平度， 在 预留通孔内壁或联接套筒内壁上设置顶升挡块， 并在弹簧隔振器与支承挡 块之间设置垫片， 垫片的中央留有顶升通孔， 通过调整垫片的总厚度可以 调节浮置板的高度和倾斜度； 支承挡块也可以是一个整体的挡环。 The support block may be a concrete structure on the inner wall of the reserved hole of the floating plate, or a metal embedded part embedded in the concrete, or a coupling sleeve embedded in the through hole of the floating plate, and then on the inner wall of the coupling sleeve A support stop is provided, wherein the support stop can be welded to the coupling sleeve in advance, and then the coupling sleeve is cast integrally with the floating plate; the support stop can also be an integral retaining ring. In order to lift the floating plate from above the floating plate and adjust the height and level of the floating plate, a lifting block is arranged on the inner wall of the reserved through hole or the inner wall of the coupling sleeve, and the spring isolator and the supporting block are arranged. A spacer is arranged between the blocks, and a jacking through hole is left in the center of the gasket. The height and inclination of the floating plate can be adjusted by adjusting the total thickness of the gasket; the support stopper can also be an integral retaining ring.
垫片结构简单， 传力大， 牢固可靠， 但不能无级调高， 为此本发明提 供了另一种可以无级调高的调节机构， 即在弹簧隔振器与支承挡块之间设 置调节螺栓和调节支承板， 浮置板通过支承挡块、 调节支承板和调节螺栓 支承于弹簧隔振器上。 其中又分为螺母上置式和螺母下置式两种形式： 螺 母上置式即螺母设置或固定于调节支承板上， 螺母下置式即螺母设置或固 定于于弹簧隔振器上。  The gasket has a simple structure, large force transmission, and is firm and reliable, but cannot be steplessly adjusted. Therefore, the present invention provides another adjustment mechanism that can be steplessly adjusted, that is, between the spring isolator and the support block. The adjusting bolt and the adjusting support plate are supported on the spring isolator by the supporting block, the adjusting supporting plate and the adjusting bolt. It is divided into two types: nut upper type and nut lower type: the nut upper type, that is, the nut is set or fixed on the adjusting support plate, and the nut lower type, that is, the nut is set or fixed on the spring isolator.
支承挡块开口及形状与弹簧隔振器的弹簧壳体上顶面、 垫片或调节支 承板的大小相容， 并可错位交叠， 即从开口上方将弹簧隔振器、 垫片或调 节支承板放入支承挡块下方后， 将隔振器、 垫片或调节支承板绕竖轴旋转 一定角度， 支承挡块与弹簧壳体上顶面、 垫片或调节支承板错位交叠。  The opening and shape of the support stop are compatible with the size of the top surface of the spring housing of the spring isolator, the spacer or the adjusting support plate, and can be misaligned, that is, the spring isolator, the spacer or the adjustment from above the opening After the support plate is placed under the support block, the vibration isolator, the spacer or the adjustment support plate is rotated by a certain angle around the vertical axis, and the support block overlaps with the top surface of the spring case, the gasket or the adjustment support plate.
浮置板本身呈板状、 框架形或梯子形， 弹簧隔振器大致均匀地分布在 浮置板两侧。  The floating plate itself is in the form of a plate, a frame or a ladder, and the spring isolator is distributed substantially evenly on both sides of the floating plate.
每块浮置板的长度一般为 10- 60米， 通常由混凝土现浇或预制而成， 也可以由混凝土和钢结构结合而成；当浮置板为预制时，可以由多块预制的 子板纵向联接构成一块较长的浮置板， 子板的端面为粗糙平面或设有凹凸 配合， 子板与子板之间用阻尼材料、 弹性材料或混凝土填充并形成联接； 子板与子板可以在纵断面凹凸配合， 也可以俯视断面上设凹凸配合， 也可 以同时在两个方向设凹凸配合。  Each floating plate is generally 10 to 60 meters in length. It is usually cast or precast from concrete. It can also be made of concrete and steel. When the floating plate is prefabricated, it can be made of multiple prefabricated pieces. The longitudinal connection of the plates constitutes a long floating plate, the end faces of the sub-boards are rough plane or have concave-convex fit, and the sub-board and the sub-board are filled with damping material, elastic material or concrete and form a joint; the sub-board and the sub-board It is possible to provide a concave-convex fit in the longitudinal section or a concave-convex fit in a plan view, or to provide a concave-convex fit in both directions.
更长的浮置道床可以由多块浮置板纵向对接而成； 为了允许浮置板热 胀冷缩， 板与板之间留有热胀冷缩间隙； 为了板与板之间能够在垂向和横 向协同受力， 相邻浮置板通过连接器连接； 所述连接器包括连接杆和滑动 套筒， 它们之间形成轴向滑动配合， 径向相互约束， 连接杆和滑动套筒分 别固定于相邻浮置板上或预埋于相邻浮置板中。  The longer floating track bed can be longitudinally butted by a plurality of floating plates; in order to allow the floating plate to expand and contract, a thermal expansion and contraction gap is left between the plates; Cooperating with the lateral direction, the adjacent floating plate is connected by a connector; the connector comprises a connecting rod and a sliding sleeve, and an axial sliding fit is formed between them, and the radial joints are mutually restrained, and the connecting rod and the sliding sleeve are respectively respectively Fixed on an adjacent floating board or embedded in an adjacent floating board.
为了保证浮置道床段与相邻道床（如固定道床)之间的平稳过渡， 与其 它道床相邻的浮置板在单位长度的平均刚度至少在垂直方向逐渐过渡到与 相邻道床相近的刚度， 其可以由同等刚度但不同排列密度的弹簧隔振器实 现， 或者由不同刚度但同等排列密度的弹簧隔振器实现。 In order to ensure a smooth transition between the floating track bed section and the adjacent track bed (such as the fixed track bed), the average stiffness of the floating plate adjacent to the other track beds gradually transitions at least in the vertical direction to the stiffness close to the adjacent track bed. , which can be made of spring isolator with equal stiffness but different arrangement density Now, it can be realized by a spring isolator with different stiffness but equal arrangement density.
为了防止隔振器水平移位， 在弹簧隔振器的上下表面设有联接装置， 该装置与浮置板和基础分别连结， 其为防滑垫板， 或者螺栓， 或者 W凸结 构。  In order to prevent the horizontal displacement of the vibration isolator, a coupling device is provided on the upper and lower surfaces of the spring isolator, and the device is respectively coupled with the floating plate and the foundation, which is an anti-skid pad, or a bolt, or a W-concave structure.
才艮据结构动力学和隔振原理， 在振动传播链中间某一环节加入弹性元 件， 降低***固有频率， 就可以隔离***固有频率 1. 4倍以上的干扰频率， 干扰频率与固有频率之比越高， 干扰振动就被隔离得越彻底， 振动没有了， 固体声也就不会产生； 阻尼的作用则是抑制***共振和结构本身的共振， 使***受干扰后很快趋于稳定。 因此隔振***固有频率越低， 隔振效果越 高， 这就要求***质量越大越好， 弹簧弹性越高越好。 但实践中***质量 和弹簧弹性在不同的节点都有制约范围， 不能随意扩大或减小， 如对于轨 下垫板、 科隆蛋和弹性套靴， 钢轨和轮对参振质量已定， 只能增大支承弹 性， 但弹性过大会导致钢轨变形过大， 横向刚度偏低， 影响行车安全； 至 今的橡胶浮置板， 其垂向弹性、 横向刚度和质量相互制约， 无法设计出既 结构筒单、 经济可行， 又能满足中高档减振要求的***。  According to the structural dynamics and vibration isolation principle, the elastic element is added at a certain point in the middle of the vibration propagation chain to reduce the natural frequency of the system, and the interference frequency of the system natural frequency of 1.4 times or more, the ratio of the interference frequency to the natural frequency can be isolated. The higher the interference vibration is isolated, the more the vibration is, the solid sound will not be generated; the damping effect is to suppress the resonance of the system and the structure itself, so that the system will become stable soon after being disturbed. Therefore, the lower the natural frequency of the vibration isolation system, the higher the vibration isolation effect, which requires the better the system quality, and the higher the spring elasticity, the better. However, in practice, the system quality and spring elasticity have constraints at different nodes, and cannot be expanded or reduced at will. For example, for the under-rail pad, Cologne egg and elastic boots, the quality of the rail and the wheel pair has been determined. Increase the elasticity of the support, but the excessive elasticity causes the rail to deform too much, and the lateral stiffness is low, which affects the safety of driving. Up to now, the vertical elasticity, lateral stiffness and quality of the rubber floating plate are mutually restricted, and it is impossible to design a structural single A system that is economically viable and meets the requirements of medium and high-end vibration reduction.
本发明浮置道床采用的弹簧隔振器， 浮置道床具有很好的各向稳定性 和弹性， 无需横向支承， 结构筒单； 弹簧隔振器从浮置板侧面或顶面就可 调平、 检修和更换， 十分方便； 浮置板长度可以根据需要设计， 可以避开 共振频率； 浮置板釆用阻尼结构， 能提高浮置板本身的结构阻尼， 抑制浮 置板本身的结构振动和噪声； 浮置板上设置阻尼元件或弹簧隔振器内集成 阻尼结构， 能吸收浮置板的结构振动能量和刚体振动能量， 提高浮置道床 的***稳定性， 提高行车安全和道床的抗震安全。 所述弹簧具有很高的弹 性及很宽的弹性范围供设计选择， 既可以设计出结构简单、 满足中档减振 要求的浮置道床替代橡胶浮置板， 也可以设计出满足高档减振要求的的浮 置道床。 附图说明  The spring isolator used in the floating track bed of the invention has a good stability and elasticity of the floating track bed, does not need lateral support, and has a structural tube; the spring isolator is adjustable from the side or the top surface of the floating plate It is very convenient to repair and replace. The length of the floating plate can be designed according to the needs, and the resonance frequency can be avoided.

实施例 1 : 如图 1、 图 2、 图 3、 图 4所示， 浮置板 l a为板状， 由混凝土现场浇注 而成， 在浮置板对应钢轨外侧位置均勾地分布两排通孔； 通孔内预埋有联 结套筒 3 , 其内壁上焊接有支承挡块 4 , 浮置板 la通过支承挡块 4弹性地 支承于弹簧隔振器 2上， 构成内置式浮置道床。 Example 1: As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the floating plate la is in the form of a plate, which is cast from the concrete, and two rows of through holes are distributed in the outer position of the corresponding rail of the floating plate; A coupling sleeve 3 is embedded, and a support stopper 4 is welded to the inner wall thereof. The floating plate la is elastically supported by the support spacer 4 on the spring isolator 2 to constitute a built-in floating track bed.
联结套筒 3和弹簧隔振器 2的内部结构如图 3所示， 包括螺旋弹簧 6a 和弹簧壳体 5 ,弹簧壳体 5由上下两个弹簧套筒组成，其中上套筒设有一可 传递弹簧支承力的上顶板 5a , 下套筒设有下底板 5b , 两者均为钢焊接件， 由一柔性密封圈 5c密封并联接为一体； 弹簧套筒内设有液体阻尼 7a，此处 为高粘度的曱基硅油， 螺旋弹簧 6a固定于弹簧套筒内， 弹簧的下部浸入液 体阻尼 7a内； 下底板 5b的底面设有摩擦系数很高的防滑垫板 5d, 防止弹 簧隔振器水平方向移位。  The internal structure of the coupling sleeve 3 and the spring isolator 2 is as shown in FIG. 3, and includes a coil spring 6a and a spring housing 5, and the spring housing 5 is composed of two upper and lower spring sleeves, wherein the upper sleeve is provided with a transferable The upper top plate 5a of the spring supporting force, the lower sleeve is provided with the lower bottom plate 5b, both of which are steel welded parts, which are sealed and integrated by a flexible sealing ring 5c; the spring sleeve is provided with a liquid damping 7a, here High viscosity silicone-based silicone oil, the coil spring 6a is fixed in the spring sleeve, the lower part of the spring is immersed in the liquid damping 7a; the bottom surface of the lower bottom plate 5b is provided with a non-slip mat 5d with high friction coefficient to prevent the horizontal direction of the spring isolator Shift.
为了能够从浮置板上方顶升浮置板并调整浮置板的高度和水平度， 在 联接套筒内壁上设置顶升挡块 3a ,并在弹簧隔振器的上顶板 5a与支承挡块 4之间设置垫片 8 , 垫片的中央留有顶升通孔， 通过调整垫片的总厚度可以 调节浮置板的高度和倾斜度。 联接套筒还设有密封防尘盖， 其固定于顶升 挡块 3a上。  In order to lift the floating plate from above the floating plate and adjust the height and level of the floating plate, a lifting block 3a is arranged on the inner wall of the coupling sleeve, and the upper top plate 5a and the supporting block of the spring isolator are arranged. A gasket 8 is provided between the four, and a jacking through hole is left in the center of the gasket, and the height and inclination of the floating panel can be adjusted by adjusting the total thickness of the gasket. The coupling sleeve is also provided with a sealing dust cap which is fixed to the jacking block 3a.
参见图 4 , 支承挡块 4开口形状与弹簧隔振器的上顶板 5a和垫片 8的 形状均为正方形， 且大小相容， 从开口上方将弹簧隔振器和垫片依次放入 支承挡块下方后， 将隔振器和垫片绕竖轴旋转一定角度， 支承挡块与弹簧 隔振器的上顶板 5a、 垫片 8错位交叠。  Referring to FIG. 4, the shape of the opening of the support block 4 and the shape of the upper top plate 5a and the spacer 8 of the spring isolator are both square and compatible in size, and the spring isolator and the spacer are sequentially placed into the support block from above the opening. After the block is below, the vibration isolator and the spacer are rotated by a certain angle around the vertical axis, and the support block overlaps with the upper top plate 5a and the spacer 8 of the spring isolator.
为了抑制浮置板本身的结构振动和噪声， 在浮置板的上下表面部分地 设有约束阻尼结构 10 , 其由一层 1-3毫米厚的高阻尼粘弹性聚氨酯阻尼层 和一 2-5毫米厚的钢板相互粘结构成。 当浮置板受轨道的振动激发产生振 动变形时， 由于约束钢板与浮置板变形不一致， 强迫阻尼材料层发生以剪 切为主的变形， 因所述阻尼材料的具有很高的损耗因子， 可将大部分振动 能量转化为热量消耗吸收， 从而能提高浮置板的结构阻尼， 抑制结构共振。  In order to suppress structural vibration and noise of the floating plate itself, a constrained damping structure 10 is provided on the upper and lower surfaces of the floating plate, which is composed of a layer of 1-3 mm thick high damping viscoelastic polyurethane damping layer and a 2-5 The millimeter-thick steel plates are bonded to each other. When the floating plate is vibrated by the vibration of the track, the deformation of the restraining steel plate and the floating plate is inconsistent, and the forced damping material layer is deformed mainly by shearing, because the damping material has a high loss factor. Most of the vibration energy can be converted into heat consumption absorption, thereby improving the structural damping of the floating plate and suppressing structural resonance.
实际使用时， 列车钢轨所承受的静动载荷传递到浮置板 la上， 浮置板 l a再通过支承挡块 4、 垫片 8和上顶板 5a传递给螺旋弹簧 6a , 由浮置板、 弹簧和阻尼构成一个固有频率较低的隔振***， 将传递到浮置板上的中高 频动载荷隔离。 由于螺旋弹簧在各个方向的弹性和承载能力可根据需要任意设计， 所 以既可以设计出满足中档减振要求的浮置道床替代橡胶浮置板， 也可以设 计出满足高档減振要求的浮置道床。 In actual use, the static load on the train rail is transmitted to the floating plate la, and the floating plate la is transmitted to the coil spring 6a through the support block 4, the gasket 8 and the upper top plate 5a, by the floating plate and the spring. And damping forms a vibration isolation system with a low natural frequency, which isolates the medium and high frequency dynamic loads transmitted to the floating plate. Since the elasticity and bearing capacity of the coil spring in all directions can be arbitrarily designed according to the needs, it is possible to design a floating track bed that meets the requirements of the mid-range vibration reduction instead of the rubber floating plate, or to design a floating track bed that meets the requirements of high-grade vibration reduction. .
浮置道床一般要求横向刚度低于其垂向刚度， 以保持道床的横向稳定 性， 由于螺旋弹簧在各个方向都具有很好的弹性， 而且其横向刚度与垂向 刚度之比也可以根据要求任意设计，所以浮置道床具有很好的各向稳定性 , 无需横向支承， 结构简单； 内置式浮置道床从浮置板顶面就可调平、 检修 和更换， 十分方便； 浮置板因为现场浇筑， 其长度可以根据需要设计， 可 以避开共振频率； 浮置板采用阻尼结构， 能提高浮置板本身的结构阻尼， 抑制浮置板本身的结构振动和噪声； 弹簧隔振器内集成有液体阻尼结构， 能吸收浮置板的结构振动能量和刚体振动能量， 提高浮置道床的***稳定 性， 提高行车安全和道床的抗震安全， 还抑制了弹簧本身的固有振动。 实施例 2:  Floating track beds generally require lateral stiffness below their vertical stiffness to maintain lateral stability of the track bed. Because the coil springs have good elasticity in all directions, and the ratio of lateral stiffness to vertical stiffness can also be arbitrarily Design, so the floating track bed has good unidirectional stability, no need for lateral support, simple structure; built-in floating track bed can be adjusted, repaired and replaced from the top surface of the floating plate, very convenient; floating plate because of the scene Pouring, the length can be designed according to the need, avoiding the resonance frequency; the floating plate adopts a damping structure, which can improve the structural damping of the floating plate itself, and suppress the structural vibration and noise of the floating plate itself; The liquid damping structure can absorb the structural vibration energy of the floating plate and the rigid body vibration energy, improve the stability of the floating track bed system, improve the driving safety and the seismic safety of the track bed, and also suppress the natural vibration of the spring itself. Example 2:
如图 5、 图 6、 图 7所示， 与实施例 1的差异在于， 浮置板 lb的下表 面设有凸台， 弹簧隔振器 2支承于该凸台外侧凹处， 形成外置式浮置板。 弹簧隔振器基本与实施例 1相近， 弹簧壳体外形为长方体， 由上下套筒组 成并用橡胶密封联接， 其内放置有两个螺旋弹簧 6a , 螺旋弹簧的上下端分 别嵌入固体阻尼材料 7b中， 如浇注后可固化的高阻尼粘弹性聚氨酯， 既为 弹簧隔振器提供了阻尼， 又起到了连接上下套筒的作用， 所述固体阻尼与 液体阻尼相比， 不怕进水， 仅从防水角度而言可以不设密封， 甚至不设弹 簧套筒。 这种多弹簧的隔振器比单个弹簧的隔振器承载能力更大， 性价比 好， 但体积也相应大， 比较适用于外置式浮置板。  As shown in FIG. 5, FIG. 6, and FIG. 7, the difference from the first embodiment is that the lower surface of the floating plate lb is provided with a boss, and the spring isolator 2 is supported by the outer recess of the boss to form an external floating type. Set the board. The spring isolator is basically similar to the first embodiment. The spring housing has a rectangular parallelepiped shape and is composed of upper and lower sleeves and is connected by a rubber seal. Two coil springs 6a are placed therein, and the upper and lower ends of the coil spring are respectively embedded in the solid damping material 7b. , such as high-viscosity viscoelastic polyurethane that can be cured after casting, not only provides damping for the spring isolator, but also acts to connect the upper and lower sleeves. The solid damping is not afraid of water ingress compared with liquid damping, only waterproof In terms of angle, there is no seal or even a spring sleeve. This multi-spring isolators have a higher load carrying capacity than a single spring isolator and are cost effective, but they are also relatively large in size, making them suitable for external floating panels.
隔振器的顶部也设有垫片， 用于调整浮置板的高度和水平。 在使用时 隔振器上下顶板分别与浮置板和基础用防滑垫板联接， 防止弹簧隔振器水 平方向移位。  The top of the isolator is also provided with a spacer for adjusting the height and level of the floating plate. In use, the upper and lower top plates of the vibration isolator are respectively coupled with the floating plate and the basic anti-slip pad to prevent the spring isolator from shifting in the horizontal direction.
外置式浮置板也无须额外的侧向支承， 可以从侧面进行调平、 检修和 更换， 十分方便。 实施例 3: 如图 8、 图 9、 图 10、 图 11所示， 与实施例 1相比， 浮置板 l c为梯子 形， 弹簧隔振器为外置式， 由两条平行的现浇混凝土梁板和多个平行的横 联杆 11组成， 此处为钢管， 在混凝土梁板内的横联杆表面设有锚固筋， 与 混凝土梁板形成牢固联接， 在混凝土梁板的上下表面及外侧面设有约束阻 尼层 10 , 其由一 2-3毫米厚的高阻尼改性沥青层和一 2-5毫米厚的钢板相 互粘结构成。 当混凝土梁板受轨道的振动激发产生振动变形时， 由于约束 钢板与混凝土梁板变形不一致， 强迫阻尼材料层发生以剪切为主的变形， 因所述阻尼材料的具有很高的损耗因子， 可将大部分振动能量转化为热量 消耗吸收， 从而提高了混凝土梁板的结构阻尼。 The external floating plate also does not require additional lateral support and can be leveled, overhauled and replaced from the side, which is very convenient. Example 3: As shown in Fig. 8, Fig. 9, Fig. 10, Fig. 11, compared with the first embodiment, the floating plate lc is ladder-shaped, and the spring isolator is external, consisting of two parallel cast-in-place concrete beams and plates. A parallel cross-link rod 11 is formed here, which is a steel pipe. The surface of the cross-link rod in the concrete beam plate is provided with anchoring ribs, which form a firm connection with the concrete beam plate, and have constraints on the upper and lower surfaces and the outer side surfaces of the concrete beam plate. The damping layer 10 is composed of a 2-3 mm thick high damping modified asphalt layer and a 2-5 mm thick steel plate bonded to each other. When the concrete beam plate is vibrated by the vibration of the track, the deformation of the restraining steel plate and the concrete beam plate is inconsistent, and the forced damping material layer is deformed mainly by shearing, because the damping material has a high loss factor. Most of the vibration energy can be converted into heat consumption absorption, thereby improving the structural damping of the concrete beam plate.
弹簧隔振器与实施例 1基本相近， 隔振器中的弹簧为磔簧 6b, 由固体 阻尼材料 7b (此处为高阻尼橡胶)将碟簧和弹簧壳体联为一体，其上顶板 5a 与浮置板螺栓联接， 下底板 5b设有一定位孔， 在安装使用时， 基础上设有 一锚固螺栓 15， 如膨胀螺栓， 定位孔套在锚固螺栓的栓帽上， 防止隔振器 横向移位， 道床安全稳定。 由于碟簧具有足够的横向刚度， 因此无需额外 的横向支承； 高阻尼橡胶和碟簧提供阻尼， 吸收振动能量； 高阻尼橡胶和 碟簧共同承载， 承载能力高； 碟簧由高阻尼橡胶包裹， 不怕进水， 仅从防 水角度而言可以不设密封， 甚至不设弹簧套筒， 结构筒单、 成本低。  The spring isolator is substantially similar to the first embodiment. The spring in the isolator is a reed 6b. The solid spring damping material 7b (here, high damping rubber) integrates the disc spring and the spring housing, and the upper plate 5a thereof. The bottom plate 5b is provided with a positioning hole. When the device is installed and used, an anchor bolt 15 is arranged on the foundation, such as an expansion bolt, and the positioning hole is sleeved on the bolt cap of the anchor bolt to prevent lateral displacement of the vibration isolator. The track bed is safe and stable. Since the disc spring has sufficient lateral stiffness, no additional lateral support is required; the high damping rubber and the disc spring provide damping and absorb vibrational energy; the high damping rubber and the disc spring are co-loaded and have high load carrying capacity; the disc spring is wrapped by high damping rubber. Not afraid of water ingress, it can be sealed from the perspective of waterproofing, even without a spring sleeve, the structure is simple and the cost is low.
隔振器中的弹簧也可以是橡胶金属复合弹簧， 本例为金属夹层橡胶弹 簧， 见图 11 , 它由多层橡胶和多层金属板 13交替叠置硫化联接而成； 其形 状可为多面柱体或圆柱体， 其中心设有固体阻尼材料（如高阻尼聚氨酯） 组成的阻尼芯 7c;金属板 13的横断面为折线状， 当金属夹层橡胶弹簧水平 方向受力时， 橡胶层 14既受剪切又受压缩， 刚度比受纯剪切时大， 通过合 理的角度设计， 以及金属板 13和橡胶层 14的厚度比设计， 金属夹层橡胶 弹簧可具有足够横向刚度， 无需额外的横向支承， 结构筒单； 橡胶和阻尼 芯可以提供阻尼， 抑制共振。  The spring in the vibration isolator may also be a rubber metal composite spring, in this case a metal sandwich rubber spring, see Fig. 11, which is formed by alternately stacking a plurality of layers of rubber and a plurality of metal plates 13; the shape may be multi-faceted The cylinder or the cylinder is provided with a damping core 7c composed of a solid damping material (such as high damping polyurethane) at the center; the metal plate 13 has a cross-sectional shape in a cross-sectional shape, and when the metal interlayer rubber spring is horizontally stressed, the rubber layer 14 is Sheared and compressed, the stiffness ratio is larger than that of pure shearing. By reasonable angle design and thickness ratio of metal plate 13 and rubber layer 14, metal sandwich rubber spring can have sufficient lateral stiffness without additional lateral support. , structural tube; rubber and damping core can provide damping and suppress resonance.
本实施例中金属夹层橡胶弹簧也适用于其它实施例， 而且橡胶也可以 用弹性聚氨酯等高分子材料替代。 实施例 4:  The metal interlayer rubber spring in this embodiment is also applicable to other embodiments, and the rubber may be replaced by a polymer material such as elastic polyurethane. Example 4:
如图 12、 图 13、 所示， 本实施例与实施例 1基本相同， 区别在于： 浮 置板 Id为框架形， 调高机构为调节螺栓 9; 调节螺栓为螺母上置式， 由螺 柱 9a和调节支承板 9b构成， 两者之间螺紋配合， 浮置板 Id通过支承挡块 4、 调节支承板 9b和调节螺栓 9a支承于弹簧隔振器的上顶板 5a上。 调节 浮置板 Id的高度和水平度时， 旋转螺柱 9a即可做到无级调高。 为了防止 螺柱松动， 螺柱上还可设防; 螺母。 As shown in FIG. 12 and FIG. 13, this embodiment is basically the same as Embodiment 1, and the difference lies in: The setting plate Id is a frame shape, and the height adjusting mechanism is an adjusting bolt 9; the adjusting bolt is a nut upper type, and is composed of a stud 9a and an adjusting supporting plate 9b, and the screw is matched with the screw, and the floating plate Id passes through the supporting block 4, The adjustment support plate 9b and the adjustment bolt 9a are supported on the upper top plate 5a of the spring isolator. When the height and level of the floating plate Id are adjusted, the rotating stud 9a can be steplessly adjusted. In order to prevent the stud from loosening, the stud can also be protected; nut.
与实施例 1 的另一区别是省去联接套筒， 在浮置板预留通孔内壁上直 接预埋嵌入支承挡块 4 ,支承挡块 4可以是一个整体的挡环，也可以是两个 以上基本中心对称布置的杆状金属体， 本结构筒单， 成本低。  Another difference from the embodiment 1 is that the coupling sleeve is omitted, and the inner support wall 4 is directly embedded in the inner wall of the reserved through hole of the floating plate. The support block 4 may be an integral retaining ring or two. More than one rod-shaped metal body symmetrically arranged in the basic center, the structure is simple, and the cost is low.
弹簧隔振器中的弹簧丝表面设有约束阻尼套 7d, 既抑制了弹簧本身的 固有振动， 又为弹簧隔振器提供了阻尼， 提高了浮置道床的***阻尼比， 提高了道床稳定性和行车安全。 实施例 5 :  The surface of the spring wire in the spring isolator is provided with a constraining damping sleeve 7d, which not only suppresses the natural vibration of the spring itself, but also provides damping for the spring isolator, improves the system damping ratio of the floating track bed, and improves the stability of the track bed. And driving safety. Example 5:
如图 14、 图 15所示， 浮置板由多块混凝土预制的子板拼接而成， 其纵 向端面设有凹凸配合， 并且对接表面 ^粗糙表面， 子板与子板之间用固体 阻尼材料 7b (如高阻尼改性沥青）填充并形成联接。 该子板的形状可以是 板状， 也可以是框架形或梯子形。  As shown in Fig. 14 and Fig. 15, the floating plate is formed by splicing a plurality of prefabricated sub-boards, the longitudinal end faces are provided with concave-convex fitting, and the abutting surface is a rough surface, and a solid damping material is used between the sub-board and the sub-plate. 7b (such as high damping modified asphalt) fills and forms a joint. The shape of the sub-board may be a plate shape, a frame shape or a ladder shape.
本实施例由于采用预制子板， 施工速度快， 适合大规模采用； 其纵向 端面设有凹凸配合， 板与板安装时容易对齐； 由于子板与子板之间的间隙 用阻尼材料填充并形成联接， 使得相邻子板之间能协同受力， 子板间的振 动能量传递被阻尼材料阻隔， 振动能量被阻尼材料吸收， 因此拼接而成的 浮置板具有很好的阻尼特性， 浮置板本身的振动和噪声将大幅衰减。 如果 弹簧隔振器内同时设有阻尼结构， 浮置道床将具有较高的***阻尼比， 可 以保证道床稳定性和行车安全。 实施例 6  In this embodiment, since the prefabricated sub-board is used, the construction speed is fast, and it is suitable for large-scale adoption; the longitudinal end surface is provided with a concave-convex fit, and the board and the board are easily aligned when being mounted; since the gap between the sub-board and the sub-board is filled with a damping material and formed The joints enable the adjacent sub-plates to cooperate with each other. The vibration energy transfer between the sub-plates is blocked by the damping material, and the vibration energy is absorbed by the damping material. Therefore, the spliced floating plate has good damping characteristics and is floated. The vibration and noise of the board itself will be greatly attenuated. If the spring isolator has a damping structure at the same time, the floating track bed will have a higher system damping ratio, which can ensure the stability of the track bed and the safety of driving. Example 6
如图 16、 图 17所示， 浮置道床一般由多块浮置板纵向排列对接组成 ,· 板与板之间留有热胀伸缩间隙，并通过连接器连接，一个接头处一般设 3-5 个连接器。 本实施例展示了浮置板与浮置板的接头和连接器； 连接器包括 连接杆 12a和滑动套筒 12b，连接杆由抗弯抗剪的钢棒制成，分为固定段和 滑动段， 连接杆滑动段与滑动套筒之间形成轴向滑动配合， 但径向相互约 束。 连接杆固定段和滑动套筒外表面分别设锚固筋， 并预埋于相邻浮置板 的端部。 As shown in Fig. 16 and Fig. 17, the floating track bed is generally composed of a plurality of floating plates longitudinally aligned and butted, and a thermal expansion and contraction gap is left between the plates and the plates, and is connected through a connector, and a joint is generally provided with 3- 5 connectors. The embodiment shows a joint and a connector of a floating plate and a floating plate; the connector comprises a connecting rod 12a and a sliding sleeve 12b, and the connecting rod is made of a steel rod resistant to bending and shearing, and is divided into a fixed section and The sliding section forms an axial sliding fit between the sliding section of the connecting rod and the sliding sleeve, but is radially constrained to each other. The connecting rod fixing section and the outer surface of the sliding sleeve are respectively provided with anchoring ribs, and are embedded in the end of the adjacent floating board.
采用连接器后， 当列车由上一浮置板向下一浮置板过渡时， 由于连接 器在垂向有很高的连接刚度， 两浮置板之间的相对位移很小， 避免了浮置 板错位对钢轨 16的弯曲和剪切， 提高了列车的运行的平稳性和安全性。 实施例 7 :  After the connector is used, when the train transitions from the upper floating plate to the lower floating plate, since the connector has a high connection rigidity in the vertical direction, the relative displacement between the two floating plates is small, and the floating is avoided. The misalignment of the plates distorts and shears the rails 16, improving the smoothness and safety of the train. Example 7:
如图 18、 图 19所示， 本实施例展示了另外一种结构的连接器 12 , 本 连接器的连接杆 12a的固定段和滑动套筒 12b分别固定于各自的底座 12c , 底座与相邻浮置板分别螺栓固定联接。 与上一实施例相比， 本连接器置于 浮置板之上， 检修或更换方便。 实施例 8 :  As shown in FIG. 18 and FIG. 19, this embodiment shows a connector 12 of another structure. The fixing section of the connecting rod 12a of the connector and the sliding sleeve 12b are respectively fixed to the respective bases 12c, and the base and the adjacent The floating plates are respectively bolted and coupled. Compared with the previous embodiment, the connector is placed on a floating board for easy access or replacement. Example 8:
参见图 20、 图 21 , 本实施例展示了浮置道床段与相邻道床的接头处， 相邻道床为固定道床， 为了浮置道床与固定道床间的平稳过渡， 采用同等 刚度的弹簧隔振器， 但在纵向单位长度的排列密度的逐渐加大， 直至浮置 道床在单位长度的平均刚度在垂直方向与相邻的固定道床相近。  Referring to Figure 20 and Figure 21, this embodiment shows the joint between the floating track bed section and the adjacent track bed. The adjacent track bed is a fixed track bed. For the smooth transition between the floating track bed and the fixed track bed, the spring with the same stiffness is used for vibration isolation. However, the arrangement density in the longitudinal unit length is gradually increased until the average stiffness of the floating track bed per unit length is similar to the adjacent fixed track bed in the vertical direction.
这样当列车驶离浮置道床段时， 其垂向刚度是渐变， 不是突变， 浮置 板与相邻道床间的相对位移很小， 避免了对钢轨 16的弯曲和剪切， 提高了 列车的运行的平稳性和安全性。  Thus, when the train leaves the floating track bed section, its vertical stiffness is gradual, not abrupt, and the relative displacement between the floating plate and the adjacent track bed is small, avoiding bending and shearing of the rail 16, and improving the train. Smoothness and safety of operation.
浮置道床段与相邻道床过渡的另一种处理方式， 是弹簧隔振器等密度 排列， 但弹簧隔振器的垂向刚度逐渐变化。 为此弹簧隔振器的弹簧可选碟 簧， 由碟簧的不同数量和叠合方式， 可以方便地组合出具有不同的垂向刚 度的弹簧隔振器。  Another treatment for the transition of the floating track bed section to the adjacent track bed is the density arrangement of the spring isolator, but the vertical stiffness of the spring isolator gradually changes. For this purpose, the spring is a spring-selectable disc spring of the spring isolator, and the spring isolator with different vertical stiffness can be easily combined by the different number and overlapping of the disc springs.
