Description

一种IV型管束瓶与集装箱框架的柔性连接装置 技术领域
本发明涉及常温压缩氢气贮运装备领域，尤其涉及一种IV型管束瓶与集装箱框架的柔性连接装置。
背景技术
大容量常温高压IV型储氢管束集装箱是一种安全、经济、高效、灵活的氢气道路运输解决方案，是推动氢能源在中国发展的关键技术。相比于传统的I型、II型、III型管束集装箱，IV型管束集装箱的优势在于：更强的氢气储运能力、更低的氢气运输成本和更长的管束瓶使用寿命。
目前，IV型管束瓶与集装箱框架均采用刚性连接，即将管束瓶两端boss结构的颈部通过螺纹+定位销/八角形卡槽的方式固定在安装法兰上，进一步用螺栓将安装法兰完全刚性地固定在集装箱框架支撑板上，以防止管束瓶发生轴向窜动和周向转动。这种刚性连接结构是针对I型、II型、III型管束瓶设计的，并没有考虑IV型瓶boss结构(金属)与复合材料缠绕层/塑料内胆(非金属)连接部位不牢固、易失效的特点。它将boss结构颈部完全固定在集装箱框架支撑板上，因此管束瓶金属与非金属连接部位将直接承受IV型瓶瓶体在质量偏心、道路运输、充放氢、环境温度变化等复杂耦合工况下产生的全部变形、力及运动倾向。这极易导致boss结构与复合材料缠绕层/塑料内胆连接部位受力状况恶化，随着损伤积累甚至引发高压氢气泄漏、扩散、火灾、爆炸等重大事故，严重降低IV型管束集装箱的安全性。
值得说明的是，IV型管束瓶的塑料内胆较软，其在复合材料层缠绕过程中的挠曲变形大、不可控因素多，导致IV型管束瓶成品的质量偏心程度高。因此，相比于I型、II型、III型管束瓶，IV型管束瓶在道路运输工况中的周向转动倾向更大。然而，国内外IV型储氢管束集装箱的设计均未考虑该不利因素的影响。
发明内容
针对现有技术的上述问题，本发明提供了一种IV型管束瓶与集装箱框架的柔性连接装置。本发明通过允许集装箱IV型管束瓶一端小范围内的轴向运动，释放管束瓶膨胀/收缩时受到的拘束力，同时利用瓶体周向转动趋势挤压阻尼块耗能，减小了boss结构与塑料内胆/复合材料缠绕层连接处承受的扭矩。本发明可以改善集装箱IV型管束瓶的受力状况，降低IV型管束瓶损伤和失效的风险，从而有效减小高压氢气泄露的可能性，提高IV型管束集装箱的安全性。
本发明的技术方案如下：
一种IV型管束瓶与集装箱框架的柔性连接装置，该装置包括阻尼块、防转块、衬套、上夹持块和下夹持块等；所述IV型管束瓶一端设置为固定端，完全约束轴向自由度，另一端设置为滑动端，能够在一定范围内轴向滑动；所述阻尼块设有凹槽和通孔；所述防转块置于阻尼块凹槽内，并与管束瓶boss结构周向刚性连接；所述衬套内表面设置螺纹，与管束瓶boss结构外螺纹连接，并利用螺紧力将防转块轴向刚性固定；所述衬套外侧设置“圆形”环凸台，与上夹持块和下夹持块组合形成的“圆形”环卡槽相配合；所述上夹持块和下夹持块利用定位销柱孔和定位销柱相互定位，两者通过抱箍长螺栓组件紧固，箍住衬套但不限制衬套周向转动；所述阻尼块、上夹持块和下夹持块的四角均开设有紧固螺栓孔，通过紧固螺栓组件实现在支撑板上的固定。
优选地，所述集装箱IV型管束瓶的boss结构颈部外侧设置两个相邻的环凸台，靠近瓶嘴侧的环凸台设为八角形凸台，靠近瓶肩侧的环凸台设为圆形凸台，且圆形凸台的直径大于八角形凸台的外接圆的直径；所述防转块设有八角形内孔，所述八角形内孔的尺寸与boss结构颈部八角形凸台的尺寸相同；所述防转块的外缘设置为八角形外缘，且每条边上设有方形突起，用于增强防转块与阻尼块连接的可靠性。
优选地，所述阻尼块的凹槽的形状与防转块的八角形外缘和方形突起结合形成的形状一致，且两者的尺寸相同；凹槽的槽深t 1、防转块的厚度t 2和IV型管束瓶的最大轴向变形量ΔL max三者需满足t 1-t 2＞2×ΔL max；防转块放置于凹槽中， 前后均需留有间隙，且前后两个间隙的宽度均大于ΔL max，用于防止防转块在所述滑动端与阻尼块碰撞；阻尼块的通孔直径需大于管束瓶boss结构的颈部圆形凸台的直径。
其中，阻尼块采用高比强度、高比模量的阻尼复合材料，其性能及结构均可以根据需求进行设计，因而阻尼复合材料可以满足本发明的结构刚度需求，实现管束瓶周向转动的可靠约束。由阻尼原理的微观机制可知，粘弹性聚合物基体+片状增强体的阻尼复合材料具有较强的内部摩擦特性，在受外部交变应力下，形变滞后于应力变化，所以这种阻尼复合材料能够将外力转化为热能消耗掉。同时，在应力作用下增强体与基体之间会发生相对的微滑移，使得阻尼复合材料的阻尼性能进一步增强。在道路运输工况下，管束瓶周向转动趋势的力是随机的、变化的，因此，阻尼复合材料可以用于消耗管束瓶周向转动趋势的能量，减小管束瓶boss结构与复合材料缠绕层/塑料内胆连接部位的扭矩，从而降低其损伤和失效的风险。
优选地，所述衬套的外侧设有“圆形”环凸台，且所述衬套的整个外侧表面需打磨光滑。
优选地，所述上夹持块设有呈“半圆形”的卡槽，卡槽的表面打磨光滑，在卡槽的左右两个截断面上均设有抱箍长螺栓孔，在靠近所述抱箍长螺栓孔的位置上设有定位销柱孔；所述下夹持块设有呈“半圆形”的卡槽，卡槽的表面打磨光滑，在卡槽的左右两个截断面上均设有抱箍长螺栓孔，在靠近所述抱箍长螺栓孔的位置上设有定位销柱；所述上夹持块的卡槽与所述下夹持块的卡槽宽度一致；所述定位销柱孔的直径与所述定位销柱的直径相同；所述上夹持块和所述下夹持块结合后，内部形成“圆形”环卡槽，所述“圆形”环卡槽的直径与所述衬套的“圆形”环凸台的直径相同。
如上所述，衬套、上夹持块、下夹持块三者相互接触的面均需打磨光滑，目的是减少衬套发生周向转动的最大静摩擦力，使防转块在管束瓶有周向转动趋势时最大限度的挤压阻尼块，增加阻尼块消耗的能量。
优选地，在所述固定端，所述上下夹持块的槽的宽度与所述衬套环凸台的 宽度一致；在所述滑动端，所述上下夹持块的槽的宽度大于所述衬套环凸台的宽度，且两者的差值大于两倍的IV型管束瓶的最大轴向变形量(即2×ΔL max)，用于提供IV型管束瓶轴向变形的空间。
优选地，在所述滑动端，衬套环凸台放置于上下夹持块结合形成的环凸槽中，前后均需留有间隙，且前后两个间隙的宽度均大于ΔL max；在所述两个间隙中均设有调节垫片。
优选地，所述调节垫片的厚度小于ΔL max，在厚度方向分层，层间胶接，各层材料的软硬不同，用于适应不同工况下管束瓶的轴向变形。
其中，调节垫片的每层材料、厚度及性能可根据需要选取和设计。一方面，用于提供滑动端的衬套与上下夹持块之间的缓冲保护，防止发生刚性碰撞；另一方面，在运输车辆加速/减速工况下，调节垫片能够为滑动端的管束瓶boss结构提供一定的轴向支撑力。
与现有技术相比，本发明具有以下有益效果：
(1)本发明利用瓶体周向转动趋势挤压阻尼块耗能，在控制管束瓶周向转动的同时，有效减小boss结构与复合材料缠绕层/塑料内胆连接部位的扭矩，从而降低其损伤和失效的风险；
(2)本发明通过允许集装箱IV型管束瓶一端小范围内的轴向运动，释放管束瓶膨胀/收缩时受到的拘束力(特别是，充放氢工况下IV型管束瓶温度变化大、散热慢、热变形量大)，改善管束瓶瓶体整体受力及变形状况，提高管束集装箱长期运行的安全性和可靠性。

具体实施方式
下面结合附图和实施例对本发明作进一步描述，需要指出的是，以下所述实施例旨在便于对本发明的理解，而对其不起任何限定作用。
实施例1
图1所示的实施例1是由九只大容量IV型管束瓶2卧置组成的集装箱，采用了3×3的管束瓶排布方式。其中，支撑板3与集装箱框架1通过焊接方式固 定连接。在不改变集装箱框架结构和管束布置的基础上，本发明提供一种IV型管束瓶与集装箱框架的柔性连接装置，如图2-图17所示，设置于管束瓶boss结构21的瓶嘴与支撑板3之间，包括阻尼块41、防转块47、衬套45、上夹持块43、下夹持块44、调节垫片48、抱箍长螺栓421及螺母422和紧固螺栓461及螺母462等。
如图3所示，在本实施例中，IV型管束瓶2左端的柔性连接装置设为滑动端，管束瓶2的该端可在一定范围内进行轴向滑动，右端的柔性连接装置4设为固定端，完全约束管束瓶2该端的轴向自由度。通过固定端与滑动端两种连接方式的组合使用，达到了如下效果：既约束了管束瓶2的轴向位移，又释放了管束瓶2膨胀/收缩时受到的拘束力。
如图4-图7所示，滑动端和固定端的柔性连接装置的基本构造相同，具体为：阻尼块41设有凹槽412和通孔413；防转块47放置入阻尼块41的凹槽412中，防转块47设有八角形内孔471，用于和管束瓶boss结构21的八角形凸台211卡死，实现防转块47和管束瓶2的周向刚性连接；衬套45的内表面设置螺纹，与管束瓶boss结构的外螺纹214连接，并利用螺紧力将防转块47轴向刚性固定，衬套45的外侧设有“圆形”环凸台451，与上下夹持块组合形成的“圆形”环卡槽相配合；上夹持块43与下夹持块44利用定位孔432和定位销柱442相互定位，两者通过抱箍长螺栓组件42紧固，达到箍住衬套45但不限制衬套45周向转动的效果；阻尼块41、上夹持块43和下夹持块44的四角均设有螺栓孔，且通过紧固螺栓组件46固定于支撑板3上。
进一步的，结合图11对管束瓶boss结构21、防转块47和阻尼块41的具体结构进行说明。这部分结构用于实现柔性地约束管束瓶2的周向转动，工作原理为：利用管束瓶2的周向转动趋势挤压阻尼材料，使其消耗能量，从而减小boss结构21与塑料内胆22及复合材料缠绕层23(复合材料通常采用碳纤维增强聚合物)连接部位的扭矩，降低其损伤和失效的风险。
IV型管束瓶2的boss结构21颈部外侧设有两个相邻的环凸台，靠近瓶嘴侧的环凸台设为八角形凸台211，靠近瓶肩侧的环凸台设为圆形凸台212，且圆形 凸台212的直径大于八角形凸台211的外接圆的直径。
值得说明的是，八角形凸台211和圆形凸台212在boss结构21上设置的位置需要与复合材料缠绕层23有足够的距离，以避免IV型管束瓶2发生膨胀时碰撞支撑板，导致其复合材料缠绕层23损伤。
防转块47设有八角形内孔471，八角形内孔471的尺寸与boss结构21颈部八角形凸台211的尺寸相同。同时，防转块的外缘设置为八角形外缘472，且每条边上设有方形突起473，用于增强防转块47与阻尼块41连接的可靠性。
阻尼块41的凹槽412的形状与防转块的八角形外缘472和方形突起473结合形成的形状一致，且两者的尺寸相同。凹槽412的槽深t 1、防转块47的厚度t 2和IV型管束瓶2的最大轴向变形量ΔL max三者需满足t 1-t 2＞2×ΔL max。而且，防转块47放置于凹槽412中，前后均需留有间隙，且前后两个间隙的宽度均大于ΔL max，用于防止防转块47在滑动端与阻尼块41碰撞。此外，阻尼块41的通孔413直径需大于管束瓶boss结构21颈部的圆形凸台212的直径，以避免妨碍管束瓶2的滑动端在膨胀或收缩时的轴向滑动。
值得说明的是，阻尼块采用高比强度、高比模量的阻尼复合材料，其性能及结构均可以根据需求进行设计，因而可以满足实施例1的结构刚度需求，实现管束瓶周向转动的可靠约束。由阻尼原理的微观机制可知，粘弹性聚合物基体+片状增强体的阻尼复合材料具有较强的内部摩擦特性，在受外部交变应力下，形变滞后于应力变化，所以这种阻尼复合材料能够将外力转化为热能消耗掉。同时，在应力作用下增强体与基体之间会发生相对的微滑移，使得阻尼复合材料的阻尼性能进一步增强。在道路运输工况下，管束瓶2周向转动趋势的力是随机的、变化的，因此，阻尼复合材料可以用于消耗管束瓶2周向转动趋势的能量，减小管束瓶boss结构21与复合材料缠绕层23/塑料内胆22连接部位的扭矩，从而降低其损伤和失效的风险。
进一步的，结合图8-图10及图12-图14对衬套45、上夹持块43、下夹持块44和调节垫片48的具体结构进行说明。这部分结构主要用于支撑管束瓶2，同时实现柔性地约束管束瓶2的轴向刚体位移，工作原理为：通过允许管束瓶2 一端小范围的轴向滑动，释放管束瓶2膨胀/收缩时受到的拘束力(特别是，充放氢工况下IV型管束瓶2温度变化大、散热慢、热变形量大)，改善管束瓶2瓶体整体受力及变形状况，提高管束集装箱长期运行的安全性和可靠性。
如图12所示，衬套45的外侧设有“圆形”环凸台451，而且衬套45的整个外侧表面需打磨光滑。
如图8-图10所示，上夹持块43和下夹持块44的结构及尺寸均相同，其区别仅在于：上夹持块43设置定位销柱孔432，而下夹持块44设置定位销柱442。具体的，上夹持块43设有呈“半圆形”的卡槽433，卡槽433的表面打磨光滑，在卡槽433的左右两个截断面上均设有抱箍长螺栓孔431，在靠近抱箍长螺栓孔431的位置上设有定位销柱孔432；下夹持块44设有呈“半圆形”的卡槽443，卡槽443的表面打磨光滑，在卡槽443的左右两个截断面上均设有抱箍长螺栓孔441，在靠近抱箍长螺栓孔441的位置上设有定位销柱442。此外，上夹持块43的卡槽433与下夹持块44的卡槽443宽度一致，定位销柱孔432的直径与定位销柱442的直径相同。上夹持块43和下夹持块44结合后，内部形成“圆形”环卡槽，“圆形”环卡槽的直径与衬套45的“圆形”环凸台451的直径相同。
值得说明的是，衬套45、上夹持块43、下夹持块44三者相互接触的面均需打磨光滑，目的是减少衬套45发生周向转动的最大静摩擦力，使防转块47在管束瓶2有周向转动趋势时最大限度的挤压阻尼块41，增加阻尼块41消耗的能量。
在固定端，上夹持块43的槽433和下夹持块44的槽443的宽度与衬套环凸台451的宽度一致；在滑动端，上夹持块43的槽433和下夹持块44的槽443的宽度大于衬套环凸台451的宽度，且两者的差值大于两倍的IV型管束瓶2的最大轴向变形量(即2×ΔL max)，用于提供IV型管束瓶2轴向变形的空间。
除此之外，在滑动端，衬套环凸台451放置于上下夹持块结合形成的环卡槽中，前后均需留有间隙，且前后两个间隙的宽度均大于ΔL max。而且，在两个间隙中均设有调节垫片48，调节垫片48的厚度小于ΔL max，在厚度方向分层，层间胶接，各层材料的软硬不同，用于适应不同工况下管束瓶2的轴向变形。
其中，调节垫片48的每层材料、厚度及性能可根据需要选取和设计。一方面，用于提供滑动端的衬套45与上夹持块43和下夹持块44之间的缓冲保护，防止发生刚性碰撞；另一方面，在运输车辆加速/减速工况下，调节垫片48能够为滑动端的管束瓶boss结构21提供一定的轴向支撑力。
以上详细描述了本发明的基本原理、主要特征和有益效果，应理解的是，以上所述仅为本发明的具体实施例，并不用来限制本发明，凡在不脱离本发明的原则范围内所做的任何修改、补充和等同替换，均应包含在本发明的保护范围之内。
