实施该发明的最佳实施例
本发明的最佳实施方式
[0071] 为了更好的解释本发明, 以便于理解, 下面结合附图, 通过具体实施方式, 对 本发明作详细描述。
[0072] 本发明主要是提供一种可以通过螺纹无级调整减振器的顶撑高度的浮置板轨道 系统。
[0073] 参见图 1, 本发明第一实施例的螺钉减振器浮置板轨道系统, 其包括浮置轨道 板 1和支撑浮置轨道板 1的若干螺钉减振器 2, 各螺钉减振器 2均匀分布于轨道外
[0074] 其中, 螺钉减振器 2包括 (结合图 8和图 9) :
[0075] 螺纹套圈 21, 其支撑浮置轨道板 1, 其具有内螺纹;
[0076] 弹性内筒体, 其设于基础物 4 (参见图 11) , 其具有弹性件 23和螺杆调高件 22 , 弹性件 23设于螺杆调高件 22下方弹性支撑螺杆调高件 22, 螺杆调高件 22具有 与螺纹套圈 21的内螺纹螺合的外螺纹, 通过旋转螺杆调高件 22或旋转弹性内筒 体来调整弹性内筒体在螺纹套圈 21中的螺合深度, 实现螺钉减振器对浮置轨道 板 1的顶撑高度的无级调整。
[0077] 其中, 螺纹套圈 21可以直接浇筑于浮置轨道板 1。 例如, 螺纹套圈 21可以预制 于浮置轨道板 1或采用现场浇筑的方式埋设于浮置轨道板 1。
[0078] 结合对比图 4与图 6或图 5与图 7可知, 由于螺纹套圈 21与浮置轨道板 1浇筑在一 起, 弹性内筒体的一端支撑于基础物 4, 另一端的螺杆调高件 22与螺纹套圈 21之 间采用螺纹连接, 因此, 可以通过旋转螺杆调高件 22的方式达到对浮置轨道板 1 无级调高的目的。 由于可以对减振器的高度作连续的无级调整, 因此, 一方面 , 其精度显著提高, 进一步的, 由于其精度的提高, 因此, 使得各个减振器对 浮置轨道板 1的支撑更均匀, 不仅可以显著提高减振效果, 而且, 可以显著提高 浮置轨道板 1的抗弯刚度和强度; 另一方面, 由于其仅需简单的旋拧动作即可实 现无级调高, 因此, 使得其操作简单, 省吋省力, 施工具有显著提高, 具有显 著的经济效益。 另外, 上述螺纹无级调整的结构设置, 还可以简化整体结构, 缩小体积, 进而减少浮置轨道板 1的空洞, 并且在必要吋, 可以将弹性内筒体旋 出更换, 使得维修简单便捷。
[0079] 其中, 当旋转螺杆调高件来进行高度的调整吋, 既可以是弹性内筒体整体旋转 , 也可以是仅有弹性内筒体中的螺杆调高件旋转, 弹性内筒体中的其他部件不 旋转或不与其同步旋转, 或者, 螺杆调高件包括相分离的上下两部分, 其外螺 纹设于上部, 且当旋转螺杆调高件吋, 仅上部旋转。
[0080] 本发明一个优选实施例的螺钉减振器浮置板轨道系统, 其中: 螺纹套圈 21还设 有外螺纹, 以加强与浮置轨道板 1的连接强度。 例如将螺纹套圈 21的外表面与混 凝土轨道板一体式浇筑, 螺纹可以增强螺纹套圈 21与混凝土的粘结力。 而且, 该种结构设置使得还可以根据需要更换螺纹套圈 21, 且其拆装方便, 施工快速 简单。
[0081] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 螺纹套圈 21的螺纹 ( 包括内螺纹和外螺纹) 可以是三角形螺纹、 矩形螺纹、 梯形螺纹 (如图 8所示) 或锯齿形螺纹。 其还可以是其他螺纹或特殊螺纹, 本发明并不以此为限。
[0082] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 螺纹套圈 21可以为尼 龙、 钢、 合成纤维或工程塑料材质制成。 其还可以是其他任何符合工程需要的 材料制成, 本发明并不以此为限。
[0083] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 弹性件 23包括在竖向 和横向具有预定刚度及弹性的螺旋弹簧 (如图 8所示) 、 碟簧、 橡胶金属复合弹 簧或碟形橡胶复合弹簧。 借此可以使得其既能起到竖向的减振作用, 又能起到 横向的隔震作用, 可以保证浮置轨道板 1在各个方向上的稳定性和减振效果, 使 其应用范围更广泛。
[0084] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 螺杆调高件 22具有沉 孔式的旋拧部供外部工具 (例如可以是后述的顶升设备 3) 旋转螺杆调高件 22。 沉孔可以为一字型、 十字型、 方形 (如图 1所示) 或六角型。 借此可以缩小其体 积, 使结构紧凑, 并便于操作, 尤其是还可以利用智能操作设备操作。
[0085] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 螺钉减振器 2还具有 密封盖 29, 与螺纹套圈 21通过螺纹连接 (如图 8所示) 。 如此可以增强其耐候性 , 延长使用寿命。
[0086] 上述任一种螺钉减振器浮置板轨道系统, 其中: 弹性内筒体还具有底筒 25, 弹 性件 23设于螺杆调高件 22和底筒 25之间。 如此可以利用底筒 25支撑于基础物 4, 使其对浮置轨道板 1的支撑更稳定。 [0087] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 弹性内筒体还具有连 接杆 26, 依次穿设螺杆调高件 22、 弹性件 23和底筒 25。 借此可以将振动限制在 垂直方向, 有效地抑制了浮置轨道板 1的侧摆, 使得支撑更平稳, 进一步降低噪 音。
[0088] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 弹性内筒体通过设于 连接杆 26的插销 28和螺母 27将螺杆调高件 22、 弹性件 23和底筒 25形成一个整体 。 借此不仅可以使得减振器的结构简化, 便于拆装等, 而且, 还可以使得其结 构更紧凑、 稳定, 进一步减少噪音。
[0089] 本发明一个优选实施例的螺钉减振器浮置板轨道系统, 其中: 底筒 25具有容置 空间, 该容置空间中设有阻尼剂 24 (例如可以是高粘度的阻尼液, 如硅油或甲 基硅油) , 例如将弹性件 23的下部浸于阻尼剂中。 借此, 减振器的阻尼力将由 弹性件 23 (如钢弹簧, 当上部荷载传来吋, 钢弹簧会提供阻尼力并产生相应变 形) 与阻尼剂 24共同提供 (阻尼剂 24的阻尼力主要由阻尼剂 24的粘着力提供) , 阻尼力主要作用于螺杆调高件 22的底面, 而且, 阻尼剂 24除了提供阻尼力之 夕卜, 还可以吸收振动能量。 另外, 需要指出的是, 减振性能和轨道板受力是难 以调和的矛盾, 小的弹簧刚度可以获得较为理想的减振性能但是会导致轨道板 受力条件恶劣, 大的弹簧刚度改善了轨道板受力但会使减振性能变差, 而通过 添加阻尼剂 24可以在一定程度上缓解该矛盾。
[0090] 本发明一个实施例的螺钉减振器浮置板轨道系统, 其中: 为了便于弹簧定位, 螺杆调高件 22的底端和底筒 25的底壁上设置弹簧定位座 (如图 8所示) 。
[0091] 参见图 2, 本发明第二实施例的螺钉减振器浮置板轨道系统, 其与第一实施例 的差别在于, 各螺钉减振器 2均匀分布于轨道内侧。
[0092] 参见图 3, 本发明第三实施例的螺钉减振器浮置板轨道系统, 其与第一实施例 的差别在于, 各螺钉减振器 2交替分布于轨道的内侧和外侧。 优选为均匀分布, 本实施例的交替分布是指一内一外, 两条轨道相邻的六个构成梅花形分布。 本 发明所述的交替分布也可以是两内两外、 三内三外等, 或者一内两外、 两内一 外等。
[0093] 本发明的浮置板轨道系统中的螺钉减振器 2可以按如下方法顶升安装, 其包括 如下步骤:
[0094] Sl、 将弹性内筒体对准浮置轨道板 1内的螺纹套圈 21, 并预紧到预定位置; [0095] S2、 在浮置轨道板 1上布置测量点, 测量轨道的结构高度, 将测量的数据传输 到中央处理器 32, 通过计算得到对预定螺钉减振器的控制信息;
[0096] S3、 中央处理器 32发送控制信号给动力装置 31, 通过旋拧螺杆调高件 22使浮置 轨道板 1达到预定结构高度。
[0097] 本发明一个实施例的顶升安装方法, 其步骤 S1中, 预紧到预定位置是指将弹性 内筒体预拧半圈螺纹。
[0098] 本发明一个实施例的顶升安装方法, 其步骤 S2中, 控制信息包括旋拧圈数。
[0099] 本发明一个实施例的顶升安装方法, 其步骤 S3中, 动力装置 31为步进电机。
[0100] 为了便于施工, 提高效率和施工的精确度, 本发明还提供一种螺钉减振器 2的 顶升设备 3 (参见图 10) , 其包括:
[0101] 动力装置 31, 具有驱动连接端 35, 用于驱动螺钉减振器 2的螺杆调高件 22的旋 转;
[0102] 测量装置 33, 测量包括浮置轨道板 1的结构高度在内的数据;
[0103] 控制装置, 具有输入端、 中央处理器 32和输出端, 输入端接受测量装置 33测得 的数据, 经中央处理器 32处理得到控制信号, 经输出端控制动力装置 31的动力 输出。
[0104] 本发明一个实施例的顶升设备 3, 其还具有行走轮 34, 供顶升设备 3在轨道上移 动。
[0105] 本发明一个实施例的顶升设备 3, 其动力装置 31为两组, 分别对应两条轨道侧 的螺钉减振器 2。
[0106] 在具体应用吋, 可以根据相应的设计参数, 选择合适的弹簧、 阻尼剂 24。 通过 调整弹簧的材质与阻尼剂 24的剂量与种类, 达到最佳阻尼比, 当浮置轨道板 1受 到激振力激扰发生振动吋, 螺钉减振器 2会产生振动惯性力反作用于浮置轨道板 1本身, 抵消输入的激振力, 以此来减小浮置轨道板 1振动反应的目的。 同吋由 于减振器中阻尼的作用, 结构振动会迅速得到削弱, 避免了浮置轨道板 1由于频 繁震动而引起疲劳破坏, 极大的延长了浮置轨道板 1的使用寿命。 [0107] 在本发明的一个优选实施例中, 安装前, 首先将螺纹套圈 21浇筑于浮置轨道板 1中, 待其凝固, 达到顶升强度, 再根据所选定的减振器型号, 将弹性内筒体对 准浮置轨道板 1中的螺纹套圈 21, 将弹性内筒体预拧半圈螺纹, 再在浮置轨道板 1上布置测量点, 运行配套的顶升设备 3, 测量轨道的结构高度, 将测量的数据 传输到中央处理器 32, 通过中央处理器 32计算每一个减振器需要调整的旋拧圈 数, 再将旋拧圈数发送至动力装置 31的步进电机, 通过步进电机的旋转, 借助 螺纹间的旋顶力把浮置轨道板 1顶升, 使得浮置轨道板 1达到规定的高度。
[0108] 综上所述, 本发明的螺钉减振器浮置板轨道系统, 由于螺钉减振器中的弹性内 筒体的螺杆调高件与螺纹套圈通过螺纹连接, 本发明的浮置轨道板可迅速而精 确地完成水平找平与顶升动作, 从而实现简单快速准确地无级调高。 而且无需 现有技术中的外底筒和垫片, 操作简单, 还可以利用智能顶升设备施工, 节省 人力和施工吋间, 施工精度更高, 克服了传统的浮置板轨道系统调高操作繁琐 复杂, 精确度差, 检修难、 成本高的缺点, 其经济效益与工程效益十分显著, 具有广阔的推广应用前景。 而且由于其结构简单、 紧凑、 体积小, 可以密集分 布, 使得浮置轨道板的受力更均匀分散, 减振效果更好, 本发明螺钉减振器可 以适用于多种厚度的浮置板。 而且, 其还可提供三维阻尼, 并适用于建筑基底 , 设备基础等场所, 都可以获得良好的减振效果。
