Description

一种液压传动平衡一体化四柱举升机 技术领域
本实用新型涉及一种平衡举升机，尤其是涉及一种液压传动平衡一体化四柱举升 机。 背景技术
目前应用于汽车维修的液压四柱举升机，通常采用钢丝绳来平衡系统来迸行平衡； 但用钢丝绳来平衡系统， 会出现钢丝绳断股、 磨损等现象， 系统内的配件需要大量的 维护， 不排除钢丝绳铆接处的幵断， 导致液压油路系统中突然失压或者增压， 从而使 得钢丝绳承受负载全部重量及冲击力的危险，液压系统易产生过压的危害， 引发爆裂。 又因为钢丝绳本身的特性， 决定了钢丝绳易延长， 在使用过程当中， 需要经常调节， 或者需要增加针对钢丝绳的机械或者电器检测机构， 从而造成系统成本的增加。 而且 以往四柱举升机钢丝绳传动和平衡的效率低， 误差大， 危险系数高， 调节困难等缺陷。 中国专利 03212785. 5公开了一种液压四柱举升机传动机构， 在立柱上部有大横梁， 大 横梁下部带有大油缸。 在活塞杆端部有拉板， 拉板上有动滑轮。 定滑轮和动滑轮之间 有板式链条。 机构工作时， 活塞带动活塞杆被抽进缸内。 同时带动 ¾板上的动滑轮向 左移动。 动滑轮分别拉动二根链条向左移动。 使汽车平台升起。 因为拉板位于两组定 滑轮的中间部位， 活塞杆移动一米， 被拉进的链条在活塞杆上部和下部也各是一米， 也就是链条被拉长二米。 所以举升高度是活塞杆运行距离的二倍。 举升速度靠油的流 速来达到。 上述专利也存在效率低， 误差大， 危险系数高， 调节困难等缺陷。 目前随 着人们生活水平和生活质量的提髙， 对举升机的要求越来越高， 不单单局限与使用性 能， 更重要的是一种智能化， 人性化和科技化。 实用新型内容 .
针对现有技术的不足， 本实用新型所要解决的技术问题是， 提供一种液压传动平 衡一体化四柱举升机， 应用液压技术， 弥补了以往四柱举升机钢丝绳传动和平衡的效 率低， 误差大， 危险系数高， 调节困难等缺陷。 为解决所述技术问题， 本实用新型所采取的技术方案是： 一种液压传动平衡一体 化四柱举升机， 其包括立柱、 动力单元、 滑台、 承车跑板和驱动系统， 滑台和立柱活 动连接， 承车跑板和滑台连接， 驱动系统和滑台和立柱连接， 驱动滑台带动承车跑板 运动， 所述每根立柱内的滑台上分别设有两个共面的主油缸和副油缸； 所述主油缸 上腔体积等于副油缸下腔体积； 所述主油缸的上腔和相邻立柱里的副油缸的下腔通过 油管顺序环形连接； 所述主油缸和副油缸均和动力单元连接。
优化的， 上述一种液压传动平衡一体化四柱举升机， 所述主油缸的上腔和相邻立 柱里的副油缸的下腔之间还设有节流阀和单向阀。
优化的， 上述一种液压传动平衡一体化四柱举升机， 所述主油缸、 副油缸上均连 接有防爆阀。
本实用新型主要是通过主油缸实现传动， 副油缸实现平衡，达到设备的正常运行。 具体是通过主油缸和、 副油缸的顺序环形排列来实现的， 以解决举升机在运行过程中 的液压传动和液压平衡问题。 本实用新型提高了传动的效率； 消餘了传动件的安全隐 患； 实现了平衡的稳定性和易调节性。 与以往技术相比，该技术传动效率高， 平衡.稳 定.而且， 由于采用此项技术， 大大降低了用户的维修费用， 按每台设备更换钢丝绳 费用 150元人民币 /副， 维修费 100元人民币 /副， 每年产量 1万台， 每年可节省 250方元 人民币， 社会效益巨大。

具体是通过以下步骤实现的：
1.每根立柱上各安装有两支油缸， 一支主油缸和一支副油缸；
2.当立柱 1上的主油缸 a上升时， 立柱 2上的副油缸 a紧跟着上升；
3.当给立柱 2上的主油缸 b输送液压油时， 立柱 3上的副油缸 b紧跟上升；

本实用新型主要是通过， 将四根主油缸和副油缸错位安装在四根立柱里， 每根立 柱里的主、 副油缸共面。 当四根主油缸同时工作进油时， 任意一根立柱里的主油缸上 升时就会带动与它共面的副油缸上升， 从而相邻立柱里的主油缸因为上腔有了空间， 下腔油不断涌入紧跟着上升， 从而实现了同步上升； 当四根主油缸在载荷作用下同时 回油工作时， 任意一根立柱里的主油缸在重物载荷和副油缸载荷作用下下降， 从而相 邻立柱里的副油缸因为下腔有了空间， 载荷不断下落， 从而实现了同步下降。
当然， 上述说明并非是对本实用新型的 制， 本实用新型也并不限于上述举例， 本技术领域的普通技术人员， 在本实用靳型的实质范围内， 作出的变化、 改型、 添加 或替换， 都应属于本实用新型的保护范围。
