技术领域
本发明涉及机械设备领域，具体而言，涉及一种双联油缸、横梁开合装置、横梁开合的方法及横梁开合控制系统。
背景技术
目前，横梁开合装置中的两个横梁的打开或关闭一般由双杆液压缸实现。由于受到材料及加工等方面的限制，双杆液压缸在实际使用中，双缸液压缸两端着力点之间的距离无法调整，当横梁的长度发生变化时双杆液压缸的使用将受到限制。
在机械设备与机械运作中，横梁开合的情况会经常遇到，一般将工件摆放在两根平行的链条上，由于工件尺寸的不同，往往需要调整两根链条的距离。而两根链条往往连接于不同的横梁，这就需要调节横梁之间的距离。
现有的横梁调节装置通常都是通过正反牙丝杠加直角转换器进行控制开合。经发明人调研发现，这种控制方法由于受到加工零部件进度、直角转换器的齿轮间隙、零部件磨损等因素影响，开合装置的同步控制精度很难得到保证，特别是长时间使用后，控制精度更难，甚至出现丝杠卡死、设备不能正常使用的情况。
同时，当横梁长度达到10米及以上时，由于使用的丝杠和直角转换器的数量的增加，要实现同步开合并长期稳定使用就更有难度。
有鉴于此，设计制造出一种易于控制，使用寿命长且能应用于较长横梁的横梁开合装置就显得尤为重要。

实施例1
如图1所示，本实施例提供一种双联油缸100，包括第一油缸10、第二油缸20和连接管30，第一油缸10与第二油缸20通过连接管30串联。
如图2所示，第一油缸10包括缸体(也就是第一缸体11)、活塞(也就是第一活塞12)和活塞杆(也就是第一活塞杆13)，第一活塞12可滑动的设置在第一缸体11内，第一活塞杆13的一端延伸至第一缸体11的外，第一活塞杆13的另一端延伸至第一缸体11的内并与第一活塞12连接。第一缸体11的内部被第一活塞12分隔并形成两个相互隔离腔室，即第一有杆腔14和第一无 杆腔15，延伸有第一活塞杆13的腔室即为第一有杆腔14。第一缸体11上设有第一进液口16和第一出液口17，第一进液口16与第一有杆腔14连通，第一出液口17与第一无杆腔15连通。
如图3所示，第二油缸20与第一油缸10的结构相同。第二油缸20的第一缸体11内部也形成两个相互隔离腔室，即第二有杆腔21和第二无杆腔22。第二油缸20的第一缸体11上设有第二进液口23和第二出液口24，第二进液口23与第二杆腔连通，第二出液口24与第二有杆腔21连通。
本实施例中，连接管30为软管。
如图1所示，第一油缸10和第二油缸20背向设置，即第一油缸10的第一活塞杆13与第二油缸20的第一活塞杆13背对背设置。连接管30的一端螺接于第一油缸10的第一出液口17处，连接管30与第一出液口17连通；连接管30的另一端螺接于第二油缸20的第二进液口23处，连接管30与第二进液口23连通。也就是说，第一无杆腔15与第二无杆腔22通过连接管30连通。
当油液从第一进液口16进入到第一有杆腔14时，第一油缸10的第一活塞杆13回缩，第一油缸10的第一无杆腔15的油液通过连接管30进入到第二油缸20中的第二无杆腔22中，第二油缸20的第一活塞杆13伸出，在此过程中，第一油缸10的第一活塞杆13和第二油缸20的第一活塞杆13同向运动。若油液从第二出液口24进入到第二有杆腔21，第二油缸20的第一活塞杆13将回缩，第一油缸10的第一活塞杆13将伸出。由于连接管30为软管，可方便的调节第一油缸10和第二油缸20的距离，从而改变整个装置两端的着力点的距离，即改变了第一油缸10的第一活塞杆13的端部与第二油缸20的第一活塞杆13的端部的距离，以增大双联油缸100的使用范围。若调节范围不能满足需求时，可将连接管30卸下更换更长的连接管30，以增大整个装置两端的着力点的距离的变化范围。
实施例2
如图4所示，本实施例提供一种双联油缸100，与上述实施例的区别在于，连接管30的结构不同。
本实施例中，连接管30为刚性管，即其不易发生弯曲。如图5所示，连接管30为伸缩结构。连接管30包括第一管体31、第二管体32和锁紧件33，第一管体31的外径小于第一管体31的内径，第一管体31的一端延伸至第二管体32内部，第一管体31内部与第二管体32内部连通，第一管体31能够相对第二管体32轴向移动以使整个连接管30的长度伸长或缩短。锁紧件33位于第一管体31与第二管体32之间，本实施例中，锁紧件33为紧定螺钉，紧定螺钉螺接在第二管体32上。当连接管30的长度调整到合适位置时，可通过紧顶螺钉将第一管体31与第二管体32锁紧。
其中，第一管体31的一端设有向外凸起的第一环形凸出部311，第一环形凸出部311的外径与第二管体32的内径相匹配；第二管体32的一端设有向内凸起的第二环形凸出部321，第二环形凸出部321的内径与第一管体31的外径相匹配。第一环形凸出部311位于第二管体32内并形成滑动密封，第一管体 31远离第一环形凸出部311的一端穿过第二环形凸出部321位于第二管体32外，第二环形凸出部321位于第一管体31外侧并形成滑动密封。当第一管体31与第二管体32向相互远离的方向运动时，最终将使第一环形凸出部311与第二环形凸出部321相抵触，从而起到限位作用，避免第一管体31与第二管体32之间发生分离。本实施例中，第二管体32上外接有进液管34，进液管34与第二管体32连通。
此外，如图6所示，第二管体32的内壁上设有多个圆周分布的凹槽322，凹槽322沿第二管体32的轴向布置，凹槽322的截面为圆弧形。第一环形凸出部311的外壁上设有多个圆周分布的凸起3111，凸起3111与凹槽322一一对应，凸起3111的外轮廓与凹槽322的内轮廓相匹配，即凸起3111的截面也为圆弧形。凸起3111卡在凹槽322内并形成滑动密封。第一管体31相对第二管体32轴向滑动时，凸起3111将在凹槽322内沿凹槽322的布置方向滑动。凸起3111与凹槽322配合后，可起到限位作用，防止第一管体31与第二管体32相对转动。此外，第一环形凸出部311上的凸起3111和第二管端上的凹槽322的设置增大了第一环形凸出部311与第二管体32间的接触面积，增强了两者之间的密封性能。
如图4所示，第一油缸10和第二油缸20背向设置，第一管体31的远离第一环形凸出部311的一端螺接于第一油缸10的第一出液口17处，第一管体31通过第一出液口17与第一无杆腔15连通；第二管体32远离第二环形凸出部321的一端螺接于第二油缸20的第二进液口23处，第二管体32通过第二进液口23与第二无杆腔22连通。当第一管体31与第二管体32相对运动而使连接管30伸长时，第一油缸10与第二油缸20将相互远离，进而增大第一油缸10与第二油缸20之间的距离；当第一管体31与第二管体32相对运动而使连接管30缩短时，第一油缸10与第二油缸20将相互靠近，进而缩小第一油缸10与第二油缸20之间的距离。本实施例中，第一油缸10与第二油缸20通过可伸缩的连接管30连接，通过调节连接管30的长度实现了对第一油缸10与第二油缸20的距离的调节，调节方式简单，易于实现。在第一油缸10与第二油缸20的距离进行调节的过程中，第一油缸10和第二油缸20只能在特定的轨迹上移动，可很好的保证第一油缸10与第二油缸20的相对位置关系。
若需要伸长连接管30时，可封堵第一进液口16和第二出液口24，并向进液管34中注入油液，进入连接管30内的油液将推动第一管体31和第二管体32相互远离，从而增长连接管30的长度。由于第一环形凸出部311上设有多个圆周分布的凸起3111，可增大与油液的接触面积，更有利于第一管体31与第二管体32的相对运动。若需要缩短连接管30时，可封堵第一进液口16和第二出液口24，并向第一油缸10与第二油缸20之间施加推力，从而使连接管30的油液从进液管34中流出，从而缩短连接管30的长度。当然，在第一油缸10和第二油缸20在工作时，第二管体32外接的进液管34将处于封堵状态。第一进液口16、第二进液口23和进液管34的封堵均可采用开关阀实现。
本实施例中，进液管34设于第二管体32上，在其他具体实施例中，进液 管34也可设置在第一管体31上，并与第一管体31连通。
本实施例的其余结构与实施例1相同，在此不再赘述。
实施例3
如图7所示，本实施例提供一种横梁开合装置200，包括第一横梁210、第二横梁220、第一连接件230、第二连接件240、第三连接件250、第四连接件260和实施例2中的双联油缸100。
其中，第一连接件230、第二连接件240、第三连接件250和第四连接件260四者的结构均相同，四者均为可伸缩的结构。
如图8所示，第一连接件230包括第一连接体231、双头螺杆232和第二连接体233。双头螺杆232的一端设有左旋螺纹，另一端设有右旋螺纹。第一连接体231螺接在双头螺杆232的一端，第二连接体233螺接在双头螺杆232的另一端。当双头螺杆232相对于第一连接体231和第二连接体233转动时，第一连接体231和第二连接体233将沿双头螺杆232的轴向运动，从而使得第一连接件230伸长或缩短。
如图7所示，第一横梁210与第二横梁220并列设置，第一横梁210平行于第二横梁220，双联油缸100的布置与第一横梁210的长度方向一致，双联油缸100位于第一横梁210与第二横梁220之间。第一连接件230的第一连接体231与第一横梁210铰接，第一连接件230的第二连接体233与第一油缸10的第一活塞杆13铰接；第二连接件240的第一连接体231与第二横梁220铰接，第二连接件240的第二连接体233与第一油缸10的第一活塞杆13铰接；第三连接件250的第一连接体231与第一横梁210铰接，第三连接件250的第二连接体233与第二油缸20的第一活塞杆13铰接；第四连接件260的第一连接体231与第二横梁220铰接，第四连接件260的第二连接体233与第二油缸20的第一活塞杆13铰接。第一连接件230与第二连接件240呈一定夹角，第三连接件250与第四连接件260呈一定夹角。第一连接件230平行于第三连接件250，第二连接件240平行于第四连接件260。
当油液从第一进液口16进入到第一有杆腔14时，第一油缸10的第一活塞杆13回缩，第二油缸20的第一活塞杆13伸出。第一油缸10使第一连接件230与第二连接件240间的夹角缩小，第二油缸20使第三连接件250与第四连接件260间的夹角缩小，从而使第一横梁210与第二横梁220相互靠近。当油液从第二出液口24进入到第二有杆腔21内，第一油缸10和第二油缸20件同时推动第一横梁210与第二横梁220相互远离。当需要对第一横梁210与第二横梁220之间的最大间距进行调节时，可通过对第一连接件230、第二连接件240、第三连接件250和第四连接件260的长度进行调节来实现。
本实施例中，可对双联油缸100中的第一油缸10与第二油缸20的距离进行调整，以适应不同尺寸的横梁。
实施例4
本实施例提供了一种横梁开合的方法，其使用上述提到的横梁开合装置 200，该方法包括：
第一进液口16进油，第一油缸10的活塞杆(即第一活塞杆13)缩回，且拉动第一连接件230和第二连接件240，第一无杆腔15内的油通过第一出液口17、连接管30和第二进液口23进入第二无杆腔22，第二有杆腔21内的油排出，第二油缸20的活塞杆(即第一活塞杆13)伸出，且拉动第三连接件250和第四连接件260；
第一连接件230、第二连接件240、第三连接件250和第四连接件260同步运动且使并列设置的第一横梁210和第二横梁220相互远离或靠近。
这里以图7中的相对位置进行说明，图7中第一油缸10和第二油缸20安装后，当第一油缸10的第一活塞杆13完全缩回、第二油缸20的第一活塞杆13完全伸出时，第一横梁210和第二横梁220极限靠近。同理，当第一油缸10的第一活塞杆13完全伸出、第二油缸20的第一活塞杆13完全缩回时，第一横梁210和第二横梁220极限远离。
同理，当第一连接件230、第二连接件240、第三连接件250和第四连接件260安装在第一横梁210和第二横梁220上后，安装第一油缸10和第二油缸20的相对位置不同，第一油缸10和第二油缸20的第一活塞杆13所对应的伸出或缩回，其在第一横梁210和第二横梁220的靠近或远离的表现也不相同。但是均可以实现第一横梁210与第二横梁220的相互靠近或远离。
也就是说，在其他的安装状态下，第一油缸10的第一活塞杆13完全伸出、第二油缸20的第一活塞杆13完全缩回时，第一横梁210和第二横梁220可以表现为极限靠近。
实施例5
参见图9，本实施例提供一种横梁开合装置200，包括第一横梁210、第二横梁220、开合驱动组件270、控制组件(图未示)以及承载组件280，第一横梁210与第二横梁220并列设置，开合驱动组件270设置在第一横梁210与第二横梁220之间，控制组件与开合驱动组件270连接，开合驱动组件270在控制组件的驱动下拉合或推开第一横梁210与第二横梁220。承载组件280设置在第一横梁210与第二横梁220的下方，配置成支撑第一横梁210与第二横梁220。
开合驱动组件270包括驱动件271、两个支撑件273、两个双向连接螺杆275以及四个关节轴承277，两个支撑件273分别固定连接于第一横梁210与第二横梁220底部相对的内侧。两个双向连接螺杆275的一端分别铰接于两个支撑件273，两个双向连接螺杆275的一端分别通过关节轴承277铰接于两个支撑件273，两个双向连接螺杆275的另一端均通过关节轴承277铰接于驱动件271，控制组件连接于驱动件271，配置成控制驱动件271以驱动两个双向连接螺杆275拉合或推开第一横梁210与第二横梁220。
在本实施例中，开合驱动组件270的两个双向连接螺杆275均呈V字型设置，且两个双向连接螺杆275的夹角随着第一横梁210和第二横梁220的开合发生变化。
开合驱动组件270的数量为多个，多个开合驱动组件270沿第一横梁210与第二横梁220的延伸方向均匀设置在第一横梁210与第二横梁220之间，且相邻的两个开合驱动组件270的驱动件271相背或相对设置，使得第一横梁210与第二横梁220的长度得以更长。
在本实施例中，开合驱动组件270的数量为两个，两个驱动件271间隔设置在第一横梁210与第二横梁220之间，两个驱动件271相背设置，使得两个驱动件271的运动方向相反。值得注意的是，开合驱动组件270的数量并不仅仅限于两个，也可以是四个、六个或者八个等，且相邻两个驱动件271的运动方向相反，开合驱动组件270的数量可以根据第一横梁210和第二横梁220的长度进行适当增减。
承载组件280包括多个承载基台(图未示)、多个第一滚轮组件(图未示)和多个第二滚轮组件(图未示)，多个第一滚轮组件固定设置在第一横梁210的底部并一一对应地抵接在多个承载基台上，第一横梁210通过多个第一滚轮组件可相对承载基台滑动，多个第二滚轮组件固定设置在第二横梁220的底部并一一对应地抵接在多个承载基台上，第二横梁220通过多个第二滚轮组件可相对承载基台滑动。
参见图10，在本实施例中，驱动件271为驱动油缸，每个驱动油缸包括缸体(即第二缸体2711)、活塞(即第二活塞2713)以及活塞杆(即第二活塞杆2715)，每个第二活塞2713容置在对应的第二缸体2711内，每个第二活塞杆2715的一端伸入对应的第二缸体2711并与对应的第二活塞2713固定连接，另一端铰接于对应的两个关节轴承277，多个第二缸体2711依次串联且相邻两个第二缸体2711通过管路连通，以使相邻两个驱动件271能够同步运动。
这里需要说明的是，当驱动件271的数量为两个时，其结构可以选用上述实施例中提及的双联油缸100。同理，当驱动件271的数量为三个时，也可以为三联油缸。
值得注意的是，此处驱动件271并不仅仅限于驱动油缸，也可以是驱动气缸或电动推杆等，在此不作具体限定。
每个第二缸体2711内具有相互隔离的有杆腔和无杆腔，有杆腔和无杆腔通过第二活塞2713分隔，相邻的两个有杆腔通过管路连通，相邻的两个无杆腔也通过管路连通。
在本实施例中，两个第二缸体2711的无杆腔相应注满液压油并通过油管连通，而两个第二缸体2711的有杆腔分别作为液压油的输入、输出端。当输入端第二缸体2711的有杆腔注入液压油时，第二活塞2713被油压推动，对应的第二活塞杆2715缩回，输入端第二缸体2711的无杆腔中的液压油通过油管进入到输出端第二缸体2711的无杆腔，使得输出端第二缸体2711对应的第二活塞杆2715伸出，输出端第二缸体2711的有杆腔中的液压油通过管路重新进入到外界的液压系统。
需要说明的是，由于两个第二缸体2711之间通过油管连接，所以只要相应地加长或缩短油管的长度，便可对驱动件271的安装位置进行调节，故两个 驱动件271的具体安装位置不受限制。这种情况也适配置成多个驱动件271的安装。
参见图11，每个支撑件273包括支撑台2731和连接件(即第五连接件2733)，每个支撑台2731贴设在第一横梁210的内侧壁或第二横梁220的内侧壁，每个第五连接件2733滑动设置于对应的支撑台2731，并铰接于对应的关节轴承277。
每个双向连接螺杆275包括螺杆本体2751以及连接头2753，每个关节轴承277固定连接于对应的螺杆本体2751的一端并与支撑件273铰接。
螺杆本体2751可以选用上述实施例所提及的双头螺杆232。
综上所述，本实施例提供了一种横梁开合装置200，将驱动油缸与两个双向连接螺杆275铰接，同时两个双向连接螺杆275分别与安装在第一横梁210侧壁和第二横梁220侧壁的支撑件273通过关节轴承277铰接，使得两个双向连接螺杆275在驱动油缸的驱动下可拉合或推开第一横梁210和第二横梁220。同时，相邻两个驱动油缸通过油管连接，并使得驱动油缸同步运动。而多个开合驱动组件270的设置则使得第一横梁210和第二横梁220的长度得以更长，使得该横梁开合装置200的适应性更强。相较于现有技术，本实施例提供的一种横梁开合装置200，通过驱动油缸来推动第一横梁210和第二横梁220的开合，结构简单，单路液压输入输出控制同步更简单方便，同时不存在使用磨损，不受零部件加工精度影响，使用寿命更长。

参见图12，本实施例提供了一种横梁开合控制系统300，包括开合控制装置301以及横梁开合装置200，其中横梁开合装置200的基本结构和原理及产生的技术效果和上述实施例相同，为简要描述，本实施例部分未提及之处，可参考上述实施例中相应的内容。
开合控制装置301包括控制器302、多个拉杆式位移传感器303、阀门组件304、报警器305以及显示器306，阀门组件304连接于驱动件271，配置成控制驱动件271运动，多个拉杆式位移传感器303固定连接于第一横梁210与第二横梁220，配置成测定第一横梁210与第二横梁220的间距，控制器302分别与显示器306、阀门组件304和多个拉杆式位移传感器303电性连接。显示器306分别与多个拉杆式位移传感器303电性连接，配置成接收每个拉杆式位移传感器303采集的位移数据并显示出来，报警器305与显示器306电性连接并依据位移数据选择性地发出报警信号。
在本实施例中，控制器302采用PLC控制器，由该PLC控制器来控制阀门组件304，进而控制驱动件271的运动。
在本实施例中，拉杆式位移传感器303为四个，四个拉杆式位移传感器303分布在第一横梁210与第二横梁220上，测定第一横梁210与第二横梁220不同位置的距离并将采集到的位移数据传递到PLC控制器，同时标定零点位置及最大位置。
阀门组件304包括第一阀门和第二阀门，第一阀门和第二阀门均连接于驱 动件271，第一阀门配置成控制驱动件271带动两个双向连接螺杆275拉合第一横梁210与第二横梁220，第二阀门配置成控制驱动件271带动两个双向连接螺杆275推开第一横梁210与第二横梁220。
在本实施例中，第一阀门和第二阀门均为电磁阀，第一阀门和第二阀门均与PLC控制器电性连接。具体地，第一阀门和第二阀门均安装在驱动油缸的进油管路上，分布控制第一横梁210和第二横梁220的拉合、推开。
在本实施例中，该横梁开合控制系统300的控制步骤如下：
步骤1：根据需要在显示器306上设定横梁间距，PLC控制器会将设定的横梁间距与当前间距进行比对。
步骤2：当设定的横梁间距大于当前间距时，PLC控制器向第二阀门发出控制信号并使得第二阀门通电，打开进油管路，使得驱动油缸带动两个双向连接螺杆275推开第一横梁210与第二横梁220；当设定的横梁间距小于当前间距时，PLC控制器向第一阀门发出控制信号并使得第一阀门通电，打开进油管路，使得驱动油缸带动两个双向连接螺杆275拉合第一横梁210与第二横梁220。
步骤3：当拉杆式位移传感器303采集到的第一横梁210与第二横梁220的间距与设定的横梁间距一致时关闭第一阀门或第二阀门。
步骤4：关闭第一阀门或第二阀门后，四个拉杆式位移传感器303将采集到的第一横梁210与第二横梁220的间距传递至PLC控制器，PLC控制器比对四个拉杆式位移传感器303的测量值，若误差在允许值范围内，则操作停止；若误差在允许范围外，则PLC控制器控制报警器305发出报警信号。
步骤5：四个拉杆式位移传感器303将采集到的第一横梁210与第二横梁220的间距传递至PLC控制器进行比对，当四个传感器的测量值中任一个超过预设的保护值范围时，断开第一阀门与第二阀门，同时PLC控制器控制报警器305发出报警信号。
值得注意的是，步骤5可以与步骤1、步骤2、步骤3或步骤4同步进行，随时监测第一横梁210与第二横梁220的距离，防止第一横梁210和第二横梁220的间距过大。
综上所述，本实施例提供了一种横梁开合控制系统300，配置成控制横梁开合，该横梁开合控制系统300通过PLC控制器来控制两个电磁阀，进而控制驱动油缸带动两个双向连接螺杆275拉合或推开第一横梁210与第二横梁220，操作简单。通过拉杆式位移传感器303向PLC控制器反馈第一横梁210与第二横梁220的距离，使得该横梁开合控制系统300可以精确控制第一横梁210与第二横梁220的开合距离。同时也通过拉杆式位移传感器303对整个系统进行有效地监控，保护系统安全。相较于现有技术，本实施例提供的一种横梁开合控制系统300，安全、高效同时操作简单，能够精确控制第一横梁210与第二横梁220的开合距离。
