Description

液压驱动的立体停车设备 技术领域
本发明涉及一种立体停车设备， 尤其是液压驱动的立体停车设 备。
技术背景
现有的立体停车设备大都采用电机驱动吊索的举升方式，但电机 驱动的弊端显而易见， 首先， 由于电机驱动要经过减速变速箱传递动 力， 运行的速度无法提高， 尤其对于高层立体停车设备， 存、 取车时 间长， 影响使用效率； 其次， 电机的运转没有死点， 一旦防护措施失 效， 很容易发生冒顶、 摔车等事故， 而为了提高安全防护措施的可靠 性又会造成制造成本的提高； 再次， 电机驱动的噪音大， 运行不够平 稳。液压式立体停车设备能够很好地解决上述问题， 液压举升器运行 平稳、 噪音小。 另外， 由于液压举升器具有足够的动力， 直接作用于 悬吊载车盘的绳索， 不需要减速变速箱传递动力， 运动速度快， 存取 车时间短； 同时， 由于液压举升器自身的结构特点， 其动作具有两个 极端的死点， 利用液压举升器的工作死点就可以避免冒顶事故的发 生。 例如， 本人的另一专利申请 "多层高速液压式立体停车设备"， 中国专利申请号： 200810015050. 1。 该发明公开了这样的一种以液 压举升器为动力的立体停车设备，但普通的液压举升器大都采用单向 截止液控单向阀和电磁换向阀串联的方式控制液压油缸的供油和回 油， 如附图 1所示， 由于立体停车设备的载车盘的荷载变化较大， 承 担不同荷载的多个并联的液压举升器在静止状态下会相互干扰，承载 较大的液压举升器对承载小的液压举升器产生反作用力，造成静态工 况不稳定。另外， 普通的液控单向阀都要采用额外铺设的控制油管提 供控制动力，这条增加的控制油管不仅提高了生产成本，也造成设计、 施工的困难，故障点增多，控制油管的维护也提高了设备的维护成本。 发明内容
本发明的目的是提供一种采用单油管供油、并联的多个液压举升 器无相互干涉、生产成本低、安装和维护方便的液压驱动的立体停车 设备。
为达到上述目的， 本发明采用如下的技术方案：
本发明所述的液压驱动的立体停车设备， 包括构成主体框架、设 置在主体框架上的载车盘， 载车盘通过绳索与液压举升器连接， 液压 举升器通过液压油管和电磁阀与液压驱动机构连接， 其特征在于： 所 述的电磁阀为电控双向截止阀，该电控双向截止阀的阀体上带有进油 口和出油口， 进油口通过油管与液压驱动机构连接， 出油口通过油管 与液压举升器连接； 阀体中连接进油口和出油口的通道上安装有阀 套， 阀套为中空的柱状结构， 其中心带有连通的弹簧腔和阀芯腔， 阀 套的侧壁上带有与出油口相通的油孔，阀套的阀芯腔中通过密封环套 装有阀芯， 在阀芯上、与油孔对应的位置是直径小于阀芯腔内径的连 杆部分， 连杆部分的前端带有锥状凸起的密封端， 该密封端与阀套的 顶端形成密封配合，连杆部分的后端是通过通过密封环与阀芯腔配合 的工作段， 工作段与电磁铁导杆靠合在一起， 电磁铁导杆连接电磁驱 动装置。
在阀芯为中空结构， 其空腔的前端与进油口连通， 阀芯的后端、 与弹簧腔对应的位置带有与弹簧腔相通的侧孔。
在阀套的弹簧腔中安装有平衡弹簧。
采用上述技术方案后，控制载车盘升降的液压举升器受电控双向 截止阀的控制，电控双向截止阀在截止的时候同时关闭进油口和出油 口， 避免与并联的其他液压举升器发生干涉； 另外， 电控双向截止阀 的动作受电磁力控制， 安装设备的时候只要铺设电线即可， 与铺设控 制油管比较，即降低了生产和安装的成本，也降低了日后的维护费用。 附图说明
图 1 是采用液控单向阀和电磁换向阀串联的立体停车设备的液 控机构的结构示意图； 图 2是本发明一个实施例的液控机构的结构示意图；
图 3是电控双向截止阀的截止状态的结构示意图；
图 4是电控双向截止阀的打开状态的结构示意图。
具体实施方式
如图 1所示，采用液控单向阀和电磁换向阀串联的立体停车设备 的液控机构由液压举升器 1、 液压驱动机构构成， 液压举升器 1和液 压驱动机构 Y之间的主油管 14上串联有液控单向阀 11、 电磁换向阀 12。 另外还有一路控制油管 13， 从液压驱动机构引出， 连接到液控 单向阀 11的控制端。
如图 2所示， 本发明所述的液压驱动的立体停车设备， 包括构成 主体框架、设置在主体框架上的载车盘， 载车盘通过绳索与液压举升 器 1连接，液压举升器 1通过液压油管和电控双向截止阀 X与液压驱 动机构 Y连接。 如图 3、 图 4所示， 该电控双向截止阀 X的阀体 2上 带有进油口 3和出油口 4， 进油口 3通过油管与液压驱动机构连接， 出油口 4通过油管与液压举升器 1连接；阀体 2中连接进油口 3和出 油口 4的通道上安装有阀套 6， 阀套 6为中空的柱状结构， 其中心带 有连通的弹簧腔 C和阀芯腔，阀套 6的侧壁上带有与出油口 4相通的 油孔 61， 阀套 6的阀芯腔中通过密封环套装有阀芯 5， 在阀芯 5上、 与油孔 61对应的位置是直径小于阀芯腔内径的连杆部分， 连杆部分 的前端带有锥状凸起的密封端 51， 该密封端 51与阀套 6的顶端形成 密封配合，连杆部分的后端是通过通过密封环与阀芯腔配合的工作段 52 , 工作段 52与电磁铁导杆 7的顶端靠合在一起， 也可以通过螺紋 将工作段 52与电磁铁导杆 7固定连接在一起。 电磁铁导杆 7连接电 磁驱动装置 8， 电磁驱动装置 8的内部结构为公知技术， 可以采用各 种结构形式的能使电磁铁导杆 7产生轴向往复运动即可。
在阀芯 5为中空结构， 其空腔的前端与进油口 3连通， 阀芯 5的 后端、与弹簧腔对应的位置带有与弹簧腔相通的侧孔。这样可以通过 阀芯 5的空腔将进油口 3和弹簧腔 C导通， 平衡两者之间的压力， 避 免由于压力不平衡造成阀芯 5动作困难。
另外， 在阀套 6的弹簧腔 C中安装有平衡弹簧 9， 该平衡弹簧 9 给阀芯 5施加一定的压力， 辅助电磁驱动装置 8的动作， 使电控双向 截止阀 X的开启更容易。
如图 3所示， 在电控双向截止阀 X截止的时候， 电磁驱动装置 8 不动作， 阀芯 5的密封端 51与阀套 6的顶端形成密封配合， 液压驱 动机构 Y送到进油口 3的液压油只能通过阀芯 5的空腔进入弹簧腔 C 中， 不能进入出油口 4。 同样， 与液压举升器 1连通的出油口 4中的 液压油只能通过阀套 6上的油孔 61进入阀芯 5的连杆部分周围和空 间 B中， 也不能进入进油口 3。 另外， 锥状的密封端 51与阀套 6顶 端直角形成的线密封配合， 密封效果好， 无泄露。 可以很好地避免并 联管路之间相互干涉。
如图 4所示， 在工作的时候， 操纵电磁驱动装置 8， 推动电磁铁 导杆 7产生轴向移动， 推动阀芯 5下移， 阀芯 5的密封端 51离开阀 套 6的顶端， 进油口 3和出油口 4通过油孔 61、 阀芯腔连通， 使液 压举升器 1产生升降动作， 完成载车盘的升降。
电磁驱动装置 8复位的时候， 电磁铁导杆 7向上移动， 此时， 如 果工作段 52与电磁铁导杆 7固定连接在一起， 则电磁铁导杆 7带动 阀芯 5上移， 阀芯 5的密封端 51与阀套 6的顶端接触， 重新密封， 将进油口 3和出油口 4之间的通道截断； 如果工作段 52与电磁铁导 杆 7的顶端只是简单的靠合在一起， 并没有连接， 电磁铁导杆 7向上 移动的时候并不带动阀芯 5， 但电磁铁导杆 7移走以后， 阀芯 5在液 压油的推动作用下， 也会向上移动， 最终密封端 51与阀套 6的顶端 接触， 完成密封。 因此， 工作段 52与电磁铁导杆 7可以通过螺紋固 定连接在一起， 也可以不连接， 而只是简单地靠合在一起， 或者如图 3、 图 4所示， 在工作段 52的上面设置一导管， 将电磁铁导杆 7的顶 端插接在导管中即可。
上述液压驱动机构为公知技术，图 1、图 2提供了两种技术方案， 但本发明的应用并不局限于这两个方案。
