说 明 书
用于平台剪式举升机二次举升机构的液压平衡装置
技术领域
本实用新型涉及一种平台剪式汽车举升机，具体的说是涉及举升机的液压平衡装 置。
背景技术
通常的剪式举升机的二次举升部分大多都采用 2根油缸加上比例分配阀体来起 到平衡作用。 应用于平台剪式举升机二次举升机构的液压平衡系统的平衡分配阀，对 液压系统当中的杂质极为敏感，容易因为分配阀本身的设计和制造质量以及液压系统 当中的杂质作用而失去平衡的效果。 从而影响举升机系统的安全性。
发明内容
针对已有技术的不足，本实用新型提供一种用于平台剪式举升机二次举升机构的 液压平衡装置。
以下详细介绍本实用新型，一种用于平台剪式举升机二次举升机构的液压平衡装 置； 包括主油缸和副油缸， 主油缸为双作用缸， 副油缸为单作用缸， 主油缸上腔与副 油缸下腔形成通路， 形成液压平衡回路； 该液压平衡装置设置并联的两套平衡回路。
优化的，上述两套平衡回路包括两套主油缸和副油缸；其中第一套平衡回路的主 油缸安装在举升机主立柱上， 副油缸安装在副立柱上； 另一套平衡回路则与之相反， 主油缸安装在举升机副立柱上， 副油缸安装在主立柱上。
优化的， 所述两套平衡回路的主油缸均设置液压防爆阔。
本实用新型的优点是：相对于现有的单回路液压平衡系统，双回路液压平衡系统 由两个并联的回路组成；它能够保证由第一回路主油缸和第二回路平衡油缸组成的子 系统在上升、停止或者下降的过程当中都能够和第二回路主油缸与 ^一回路副油缸组 成的子系统完全地平衡。 同时， 因为主油缸内安装了液压防爆阀， 液压系统内任一部 件失效， 都能够保证举升机系统的平衡和安全。能够在汽车举升机系统内完全代替分 配阀平衡系统。 ' 说 明 书
