Description

一种轻质危化品储运罐及使用该储运罐的铁路罐车 技术领域
本发明涉及一种运输液体材料的容器，具体涉及一种轻质危化品储运罐及使用该储运罐的铁路罐车。
背景技术
目前，铁路罐车是一种物资运输过程中重要的工具，铁路罐车运输的物质多种多样，结构和性能要求也不尽相同。特别是装运轻质危化品罐车的结构和性能参数还有许多不合理之处，运输经济性相对较差，出现事故时罐车的自我保护机制不够，导致目前该类罐车的实用性、可靠性都不尽人意。
具体来讲，已有危化品介质铁路运输装备主要为70t级的GQ70、GHA70型等罐车，采用GQ70运输汽油、航空煤油、煤制油等介质“亏吨”(铁路计费方式按车辆标记载重与里程数收费，即t.km/元，GQ70标记载重70t，装运汽油时最多可装载59.1t，与标记载重相比多付11t货物运费)严重；
若为了提高运输效率，解决“亏吨”问题，从而增加罐车中运输罐的体积，又无法满足运输线路上的限高、限宽要求，同时由于现有罐车的筒体采用两节直锥体的组合结构，当在增加运输罐体积(增加两节直锥体的小端和大端尺寸或单独增大小端尺寸)后会使罐体重心超过安全阈值，当受到冲击力较大的情况时，则会出现倾覆现象。
同时，现有的铁路罐车的人孔、安全阀处缺少在出现事故情况下的安全防护，一旦发生脱轨、倾覆，极有可能造成罐体破裂，介质泄漏引发事故。
发明内容
为了解决背景技术中的问题，本发明设计了一种在满足运输线路限高、限宽、限长的前提下，既增加了运输罐的容积又确保了重心不会超过安全阈值的轻质危化品储运罐。
同时，还提出了使用上述储运罐的铁路罐车。
本发明的具体技术方案：
一种轻质危化品储运罐，包括前封头、筒体以及后封头；其改进之处是：所述筒体包括两节端部正锥体以及两节中间直锥体；
两节端部正锥体的小端分别与前封头、后封头连接，两节端部正锥体的大端分别与两节中间直锥体的小端连接，两节中间直锥体的大端相互连接；
设，端部正锥体的小端尺寸为R1；端部正锥体的大端以及中间直锥体的小端尺寸均为R2；中间直锥体的大端尺寸为R3；
端部正锥体的长度为L1；中间直锥体的长度为L2；
其中，端部正锥体的底部倾斜角为：
arctan{(R2-R1)/2×L1}＝3.95°±0.05°；
中间直锥体的底部倾斜角为：
arctan{(R3-R2)/L2}＝0.4°±0.05°；
端部正锥体和中间直锥体的长度比为：L1/L2＝0.43。
进一步地，由于上述设计保证了运输罐的重心不会超过安全阈值，同时进一步的增加运输罐的装载量，运输罐各个部分尺寸都相应地进行了放大，具体是：所述R1为3070mm，R2为3270mm，R3为3295mm，L1为1450mm，L2为3360mm。
进一步地，为了确保运输罐整体强度同时尽量的节省成本，所述前封头、 后封头、端部正锥体、中间直锥体均采用345R制作，且前封头、后封头、端部正锥体的壁厚均为12mm，中间直锥体的壁厚为10mm。
进一步地，为了提高事故状态下对人孔和安全阀等设置在运输罐上附件的防护，所述运输罐还包括防护装置，所述防护装置包括沿运输罐轴向平行设置两组安全护栏，所述安全护栏包括弧形底板、固定框架以及至少一条肋板；
弧形底板固定安装在筒体上，且与筒体的形状相适配，固定框架固定安装在弧形底板上，且固定框架顶部至筒体表面的高度大于安全阀和/或人孔顶部至筒体表面的高度；肋板设置在矩形框架与弧形底板。两组安装护栏之间的位置安装需要保护的人孔和安全阀等附件。
为了进一步的增强固定框架的强度，固定框架包括外边框以及设置在外边框内的腹板。
为了便于安全护栏的起吊安装，同时减少运输罐在运输过程中的风阻，所述腹板上开设有至少一个起吊卸阻孔。
基于上述运输罐，本发明还提出了一种使用该运输罐的铁路罐车。
为了避免铁路罐车在运输过程中牵枕位置安装的牵枕走台在通过弯道处不会与建筑限界发生干涉，同时确保设备整体外观的美观大方，所述走台包括设置在前封头中部的两块矩形踏板以及设置在前封头两边的两块平行四边形踏板。
本发明的有益效果是：
1、本发明采用将现有运输罐的筒体由两节直锥体的组成方式(底部的倾斜角整体为1.15°)，改进成由两节端部正锥体和两节中间直锥体组成的方 式(底部的倾斜角由一段3.95°和一段0.4°组成)，减小了筒体底部的倾斜角，从而增大了运输罐的容积，使得运输效率大大提升，同时，两节端部正锥体结构使得筒体的重心不会超过安全阈值，确保了运输罐的抗冲击力。
2、本发明设置了两组平行安装的安全护栏，提高事故状态下对人孔和安全阀等设置在运输罐上附件的防护，防止液体介质的泄漏，进一步地提高了罐车的安全性。
3、本发明的安全护栏上安装腹板并在腹板上设置起吊卸阻孔，不仅使得安全护栏便于拆装，同时也减小了运输罐车运输过程中风阻的影响。
4、本发明的将牵枕走台的外形进行了变化，避免了牵枕走台在通过弯道处与建筑限界发生干涉的问题，提高了铁路罐车的安全性。

具体实施方式
下面根据一种铁路罐车的具体实施例对本发明所需要保护的结构进行详细的描述。
如图1和图2所示，一种铁路罐车，其包括行走结构1、底架2、运输罐3、牵枕4、端梯5、顶部走台6、牵枕走台7、防护装置8以及人孔9、安全阀10。
运输罐的特殊设计
如图3所示，为了使得铁路罐车在运输过程中满足限界要求，并同时满足运输罐重心不会超过安全阈值的情况，还需要提高运输罐的装载量，本实施例中提出了一下特殊的运输罐设计，其包括前封头31、筒体32以及后封头33；筒体32包括两节端部正锥体321以及两节中间直锥体322；
需要说明的一点是：所谓正锥体即就是剖面为等腰梯形的筒形结构，所谓直锥体就是剖面为直角梯形的筒形结构。
两节端部正锥体321的小端分别与前封头31、后封头33连接，两节端部正锥体321的大端分别与两节中间直锥体322的小端连接，两节中间直锥体322的大端相互连接；(此处需要说明的是：两节端部正锥体与前封头、后封头之间、两节端部正锥体和两节中间直锥体之间均采用焊接的方式进行连接，并且焊接结束后还需进行拼接焊缝内部无损检测，要求焊缝达到国标要求)
且需满足以下关系：
设，端部正锥体321的小端尺寸为R1；端部正锥体321的大端以及中间直锥体322的小端尺寸均为R2；中间直锥体322的大端尺寸为R3；
端部正锥体321的长度为L1；中间直锥体322的长度为L2；
其中，端部正锥体的底部倾斜角为：
arctan{(R2-R1)/2×L1}＝3.95°±0.05°；
中间直锥体的底部倾斜角为：
arctan{(R3-R2)/L2}＝0.4°±0.05°；
端部正锥体321和中间直锥体322的长度比为：L1/L2＝0.43。
由于上述设计保证了运输罐的重心不会超过安全阈值，为了进一步的增加运输罐的装载量，运输罐各个部分尺寸都相应地进行了放大，具体是尺寸：R1为3070mm，R2为3270mm，R3为3295mm，L1为1450mm，L2为3360mm。并且在满足现有装卸设备长度尺寸要求(12206mm)的情况下，还将运输罐的总长度(筒体+前封头+后封头)设计为11249mm。
通过以上设计，运输罐底部的倾斜角从现有运输罐的1.15°改变成本发明中两段倾斜角的布置(一段为3.95°，一段为0.4°)，使得当运输罐的外形尺寸以及长度增大时(运输罐装载量增大时)，还能确保运输罐的重心在安全阈值之内，避免了倾覆现象的发生。
以下将现有GQ70车型运输罐的筒体和本发明的筒体进行容积大小计算对比结果：
被计算GQ70车型罐体的筒体由对称的两段直锥体组成，大端外径为3170mm，小段外径为3070mm，筒体总长度为9780mm，筒体底部的倾斜角为1.15°，计算所得容积为73.8m 3。
本发明的筒体最小端外径R1为3070mm，中间外径R2为3270mm，最大端外径R3为3295mm，R1-R2段长度为1450mm，R2-R3段长度为3360mm，筒体总长度为9620mm，两段筒体的倾斜角分别为3.95°和0.4°，计算所得容积为 78.8m 3；由此可见，本发明的筒体容积较现有GQ70车型的容积在筒体长度减小的情况下，容积依然增加了5m 3。本发明的运输罐在满足了铁路限界和与现有地面装卸设施匹配的情况，大大提高了运输经济性。
本实施例中前封头31、后封头33、端部正锥体321、中间直锥体322均采用345R制作，且前封头31、后封头33、端部正锥体321的壁厚均为12mm，中间直锥体322的壁厚为10mm。原GQ70车型封头壁厚10mm，材质为295A，筒体采用上下板拼接，上罐板壁厚8mm，下罐板壁厚10mm，材质均为345R，由于本实施例的运输罐局部壁厚增大和材质的更换，在保证了成本较低的情况下，强度和防泄漏性有了更大的提升。
人孔、安全阀等附件的防护装置
为了提高事故状态下对人孔和安全阀等设置在运输罐上附件的防护，本实施中的铁路罐车在运输罐上还设置了防护装置8，防护装置包括沿运输罐轴向平行设置两组安全护栏81，两组安全护栏81之间安装人孔9、安全阀10等附件；如图4和5所示，其结构如下：
安全护栏81包括弧形底板811、固定框架812以及至少一条肋板813；
弧形底板811固定安装在筒体32上，且与筒体32的形状相适配，固定框架812固定安装在弧形底板811上，且固定框架812顶部至筒体32表面的高度大于安全阀10和/或人孔9顶部至筒体32表面的高度(当出现翻车事故时，首先接触受到损伤的为安全护栏而不是人孔、安全阀等附件，降低了泄漏风险)；肋板813设置在固定框架812与弧形底板811之间。为了进一步的增强固定框架812的强度，固定框架812包括外边框8121以及设置在外边框8121内的腹板8122。腹板8122上开设有两个起吊卸阻孔8123，目的是为了 便于安全护栏的起吊安装，同时减少运输罐在运输过程中的风阻。
端梯、顶部走台以及牵枕走台的设计
本实施例中供操作人员使用的端梯5由梯柱、脚蹬、扶手、球形接头等组成。梯柱为圆管折弯成型。脚蹬由3mm钢板折弯成槽型结构，脚蹬表面设有凸台和孔，具有防滑作用。球形接头起扶手与梯柱连接作用。封头扶手为圆管折弯件，安装于封头上，便于蹬梯和操作手制动机。
顶部走台6两侧设置由扶手、球形接头组成的护栏以及工人行走的踏板，踏板采用防滑结构，操作安全性和人性化程度进一步提升。
如图2所示，牵枕走台7包括设置在前封头31中部的两块矩形踏板71以及设置在前封头31两边的两块平行四边形踏板72。为了避免铁路罐车在运输过程中牵枕位置安装的牵枕走台在通过弯道处不会与建筑限界发生干涉，同时确保设备整体外观的美观大方。
