Description

液压顶举全自动控制装置
本发明涉及一种液压连续项举载荷的全自动控制装置。
现有液压项举机具，如千斤顶，趋近载荷的速度很慢，效率底下，又需施加外力复位。为此，近年一些已公告的专利申请，如CN2061169U、CN2101038U、CN2107454U、CN2155365Y、CN2172760Y、CN2194350Y、CN1112517A等，为提高工作效率作了技术改进，其中前四种技术方案以增加油泵系统来实现加快速度，后三种技术方案以增加油缸系统来提速，都有结构复杂、可靠性差、操作烦琐等缺点。
本发明的目的，是要提供一种结构简单、便于操作，以机械、气体、液体三种方式组合传递动力的液压顶举全自动控制装置。
发明是这样实现的：在油缸的无杆端置有顶举弹簧，与油泵相接的进油管上，装有通过单向补油阀至油箱的支管、蓄能器、机控单向阀、回油转阀，依次用油管连接，油缸有杆端的排油管接通蓄能器与机控单向阀之间的油管，回油转阀由前截止单元和后截止单元、转把组成，前截止单元接油缸无杆端的回油管，后截止单元的油管接油箱。
本发明用弹簧的机械力完成轻载自动到位，用液压完成重载增力和向蓄能器供能，再由蓄能器释放压力油与弹簧作用力合并完成自动到位。只要关开一次回油转阀，即全自动完成全部控制过程，结构简单，操作方便。重物下落的巨大能量由蓄能器吸收和缓冲，不但载荷下降时安全平稳，且将重物的势能转换成可利用的动能。
下面结合附图介绍本发明。
图1为发明的结构原理图。
参照图1，由油泵1和油缸2连接的进油管上设有接油箱10、支管17，支管中装有单向补油阀16，油缸2内装有活塞1 8和活塞杆3，无杆端置有弹簧15，油缸底部通过回油管14接回油转阀13，转阀13包括前截止单元12和后截止单元11、以及带碰点8的转把9，在前后两截止单元的连接管上，接带碰杆19的机控单向阀7的输入端，其输出端通过油管接蓄能器6。油缸2顶部有排油管4与蓄能器6连通，在油缸2的排油管4下面还装有分流槽5与蓄能器连通，为同一阀杆上的两道高压密封的前后两截止单元12、11，常态，两截止单元均开通，油缸无杆端无压。置于工作位置后，通过操作转把9，后截止单元11，截止油箱通道。碰点8打开机动单向阀1，蓄能器6中的油和经单向补油阀16来的油一起进入油缸活塞下端，与弹簧15作用力合并顶举活塞18，使活塞杆3迅速接触被顶工件。紧接着前截止单元12关闭，油泵1供油加弹簧力缓举重物上升，活塞18至高位，油液经分流槽进入蓄能器6。工作结束卸荷时，截止单元12先打开，重物下落，油缸无杆端中的油经机控单向阀7入蓄能器6，接着碰点8脱离机控单向阀碰杆19，蓄能器内油压被锁闭，后截止单元11打开，蓄能器油压使油缸活塞回到原位，并由机控单向阀7锁闭油路而稳定于低位。
