Description

一种叉车起升油缸
技术领域
本发明涉及油缸领域,具体是一种叉车起升油缸。
背景技术
叉车是工业搬运车辆,其用于对成件托盘货物进行装卸、堆垛和短距离运输作业。叉车中各种动作部件一般是通过油缸进行驱动的,特别是起升动作部件。现有技术叉车中起升动作部件的驱动油缸结构简单,工作不稳定,内部活塞杆运动能力差,无法满足叉车性能需求。
发明内容 本发明的目的是提供一种叉车起升油缸,以解决现有技术叉车中起升驱动油缸工作不稳定,活塞杆运动能力差的问题。
为了达到上述目的,本发明所采用的技术方案为:
一种叉车起升油缸,其特征在于:包括中心轴水平的缸筒,缸筒右端缸口连接有缸底,缸底中设有通入缸筒中的进油孔,缸筒左侧底部连通有管接头,缸筒内右端滑动装配有活塞,活塞侧壁上左、右侧分别设有环槽,其中活塞侧壁右侧环槽中安装有U形密封圈以及限位U形密封圈的挡圈,活塞侧壁左侧环槽中装配有支承架,活塞左端中心水平连接有活塞杆,缸筒左端缸口中同轴套接有缸盖,所述活塞杆左端从缸筒左端缸口连接的缸盖左端穿出,缸盖内左侧与活塞杆之间装配有密封圈,缸筒左端缸口中同轴装配有导向套,导向套内同轴安装有钢背轴承,所述钢背轴承套在活塞杆上并与活塞杆相对滑动配合。
所述的一种叉车起升油缸,其特征在于:所述缸盖内右侧与缸筒之间装配有O形密封圈。
所述的一种叉车起升油缸,其特征在于:所述缸盖内左端与活塞杆之间还装配有防尘圈。
所述的一种叉车起升油缸,其特征在于:所述活塞杆右侧靠近活塞位置还同轴装配有调整套。
所述的一种叉车起升油缸,其特征在于:所述活塞左端中心设有凹槽,活塞杆右端中心成型有凸头,且活塞杆右端凸头安装在活塞左端凹槽中,且凸头侧壁上设有环槽,所述凹槽中设有嵌入凸头环槽中的钢丝挡圈。
所述的一种叉车起升油缸,其特征在于:所述缸底右端插接有圆柱销。
本发明结构稳固,在缸筒左端缸口中钢背轴承,可有效提高活塞杆的运动能力,且整体密封结构合理,提高了工作时的稳定性。
附图说明
