Description

一种适用于工业车辆的顶升立柱 技术领域
本发明涉及自动化机械设备领域，具体涉及一种适用于工业车辆的顶升立柱。
 背景技术
工业车辆是指用来搬运、推顶、牵引、起升、堆垛或码放各种货物的动力驱动的机动车辆。常见的工业车辆有叉车、侧叉车、牵引车、搬运车、堆高车等等。
工业车辆在结构上，往往包含车身、手柄、货叉、电池箱、油缸、泵站、控制器等部件，其中，油缸与车身连接，车身与货叉连接，当油缸中的活塞杆顶出时，带动车身和货叉升降。
在车身被活塞杆顶起时，为了保持稳定性，特别需要组装一对连接骨架。连接骨架位于车身两侧，增加其结构强度，避免车身被活塞杆顶起时损坏或者上翻。但是这样的结构，一方面增加了车身的复杂度，增加了产品的成本和装配的时间，另一方面，在实际工作中，受杠杆作用的影响，车身与活塞杆抵触的位置依然会有上翻不平稳的现象出现。

 本发明的最佳实施方式
实施例1，如图1和图2所示，一种工业车辆，可以是叉车、堆高车、分拣车等不同种类的车辆类型，本技术方案以叉车为例。包含主车架2，可将整个车辆大致划分为两个总成单位，其中，总成A包含手柄32和驱动轮总成33，与现有技术不同的是，手柄32直接与驱动轮总成33，而非通过泵站支架或者主车架进行连接。
另一个，总成B，包含主车架2，主车架2上连接着立柱体1。顶升装置51、电池箱箱体4、泵站53和控制器52，均在这个总成B的部分。具体的，顶升装置51可以使用油缸类的部件，泵站53用于给顶升装置供油。泵站53和控制器52均可以通过连接件与主车架2固定连接，油缸一端同样连接在主车架2上，另一端，即活塞杆的一端与立柱体1抵触，随着顶升装置51的运作，立柱体1连同货叉31就在竖直方向上进行升降。
在本案中，正如上文所述，总成A包含手柄32和驱动轮总成33，而总成B则包含了顶升装置51、控制器52、泵站53、主车架2、立柱体1等部件，在操作转向的过程中，总成A和总成B之间发生相对转动，但是总成B之间的各个部件是不存在相对转动的。
这样的设计，使得在转向过程中，泵站53、控制器52和顶升装置51不作为转动件，而作为静止件，磨损少，不容易产生故障或损坏；另一方面，这几个部件不转动，就不容易对操作者产生夹手的风险；再次，由于泵站53、控制器52和顶升装置51和电池箱箱体4之间不相对转动，其中各个部件之间相互连接的电线就保持相对静止，电线就不容易折断或者损坏。
如图1、图2和图3所示，立柱体1包含上顶板11、位于两侧的两个侧板12和背板13，还包含覆盖罩15。上顶板11、侧板12、背板13和覆盖罩15相互配合围成一个容纳空间，顶升装置51、控制器52和泵站53均安装在这个容纳空间里。由于这几个包裹部件的存在，在外侧看不到顶升装置51、控制器52和泵站53这些部件，车辆的整体美观性得到提升。
与现有技术不同，关于顶升装置51、控制器52和泵站53的空间排布，本案做了重新设计。如图2所示，在现有技术中，图中的控制器52、顶升装置51、泵站53，原本是一字排开，依次从左到右排布。但在本案中，首先，顶升装置51放在了图中最右侧，即最靠近背板13的位置，而控制器52和泵站53则位于同一个侧面，这两个部件距离背板13的位置相同。
这样的位置设计，存在至少两个有益效果。一方面，顶升装置51与背板13更靠近，即顶升装置51与上顶板11的下表面存在抵触点，这个抵触点的位置更靠近背板13。在杠杆效应下，抵触点与背板13之间的距离更短，力臂更短，整个上顶板11的稳定性就更强，上顶板11不太容易被掀起从而造成倾斜或者破损。另一方面，这样的空间排布使得顶升装置51位于上顶板11、侧板12和背板13围成的空间内，而控制器52和泵站53又是同侧同距放置，使得这样的放置方式更为紧凑，整个车辆的车身长度被缩短，拥有更小的转弯半径。
立柱体1也采用了加固设计。如图1、图2和图3所示，侧板12上端与上顶板11连接，同时侧板12的侧面与背板13连接，侧板12增加了上顶板11的结构强度，防止上顶板11的形变和倾斜。在背板13的背部，即远离顶升装置51一侧设有背加固板16，被加固板16侧面与背板13连接，底面与其他连接板连接，也是增加了对于背板13的后背支撑力。
对于空间的位置关系,本案有特别的设计,如图2所示, 两个侧板12和一个上顶板11形成一个半包围空间，顶升装置51,即油缸和活塞杆安装在这个半包围空间中。需要特别指出的是,这里所讲的半包围空间,指的是顶升装置51在小车侧端侧视的角度看,位于这个半包围空间中,即从图2上,以正对屏幕的角度看图2, 侧板12部分遮挡或者完全遮挡了顶升装置51。
这里还需要说明的是，本案的侧板12、背板13和上顶板11，均是立柱体1的一部分，为承力部件，而非现有技术的一些外壳或罩体。现有技术的外壳或罩体只是覆盖部件，而没有承力效果，与本案中的侧板12、背板13和上顶板11有着本质性的区别。
本案的顶升原理是，泵站53、控制器52和顶升装置51的油缸缸体通过连接件与主车架2连接。立柱体1与货叉31连接，立柱体1又与顶升装置51的活塞杆抵触，当活塞杆将立柱体1升起时，货叉31就随之举升。
在本案中，背加固板16的作用有两个，一个是在顶升的过程中，给整个立柱体1背部的结构支撑力，增加其平稳性；另一个作用是作为支撑件去支撑和固定电池箱。
如图4、图5和图6所示，电池箱包含电池箱箱体4，上部位置设有便于工人提手操作的提手槽41，其底部位置开设有固位槽42，固位槽42同样在竖直方向延伸。
为了便于电池箱箱体4的安装和滑入，设有滑入装置。具体的，在背加固板16上设有导轨17，而在固位槽42中还开设有与导轨17配合的滑轨槽44，整个电池箱能更顺利地滑入和滑出。
更进一步的，由于工人手持电池箱下放过程中，视野会被电池箱遮挡，为了增加安装的顺利性和便捷性，在导轨17上设有导向坡171，在电池箱箱体4靠近固位槽42位置也相应的设有如图4所示的滑入坡43。导向坡171和滑入坡43均倾斜设置，倾斜的角度一致，坡度彼此配合，起到滑入安装导向的作用。
电池箱中的电池部件需要诸如电线或者其他连接件与主车架2上的部件电连接，所以在电池箱箱体4上特别设有连接件留口45，位置同样设在底部靠近固位槽42的位置。
如图8所示，在顶升装置51的空间布置上，本技术方案也做了优化设计。具体的，侧板12的上部与上顶板11连接的部分为上连接部121，侧板12的下部与主车架2或其他的第三方连接受力部件连接，这部分为下连接部122。上文提到的降低顶升装置51抵触点的力臂效果和进一步缩短车体长度这两大效果，都是通过顶升装置51的空间布置优化来实现的。
在本案中，需要顶升装置51在车辆宽度方向上的投影在侧板12的范围内，至少部分重合。而具体的，就是上连接部121、下连接部122与顶升部件51这三个部分的位置关系。
在车辆长度方向上，上连接部121和下连接部122至少一个较顶升装置51更远离货叉31。如图9所示，图9绘制的空间布局，右边即是货叉31的方向图中未画出，顶升装置51更靠右，而上连接部121和下连接部122两个部件，延伸的范围都更靠左，即更远离货叉31的方向。这样的空间布置，是本技术方案的空间布局。
如图10和图11，图10和图11就不是两个部分都更靠左，而是只有一个部分较顶升装置51更靠左。图10是上连接部121较顶升装置51更远离货叉31，图11是下连接部122较顶升装置51更远离货叉31。这样两种空间布局依然能起到优化力臂加强稳固性的作用，也是本技术方案的空间布局。
图12和图13则不同，在图12中，整个侧板12都更靠右，顶升装置51更靠左，上连接部121和下连接部122都较顶升装置51更靠近右边即货叉31的方向，这样无法起到缩短力臂，优化稳定性的效果，不是本技术方案的空间布局。在图13中，虽然顶升装置51也是在车辆宽度方向上的投影与侧板12部分重叠，但是这是因为侧板12的形状中间宽两边窄。在图13中，上连接部121和下连接部122依然都较顶升装置51更靠近右边即货叉31的方向。故，图12和图13所代表的技术方案不是本专利申请文件要求保护的空间布局。
此外，在实际生产中，上连接部121和下连接部122是一个焊合的部位，这个部位有一定的延伸长度，上文说的上连接部121和下连接部122较顶升装置51更远离货叉31的意思其实是该连接部最远离货叉31的一端的部位，较顶升装置51更远离货叉31。即图中最左的位置要比顶升装置51更靠左，即“所述上连接部121和所述下连接部122至少一个,其部分较所述顶升装置51更远离货叉31。”
此外，在车辆转向过程中，手柄32需要左右摆动，手柄32的摆动轨迹在水平面上的投影形成了一个圆弧状的空间，手柄32的摆动轨迹以及这个轨迹的延长线形成了一个圆。上文提到的侧板12、顶升装置51、控制器52、泵站53等部件都位于这个圆，这个范围之中。
