齿条5,与一个剪刀臂3连接,该剪刀臂3与底盘1滑动连接;
卡扣6,在底盘1上设置,具有:
单向锁定状态,卡扣6依靠弹性力与齿条5保持接触,允许剪刀叉机构2带动平台4远离底盘1;
解锁状态,卡扣6克服弹性力动作,与齿条5分离,允许剪刀叉机构2带动平台4靠近或远离底盘1。
对于上述实施例公开的升降平台,领域内技术人员可以理解的是,剪刀叉机构2在动作过程中,与底盘1、平台4滑动连接的剪刀臂3会相对于底盘1、平台4滑动,带动平台4靠近或远离底盘1,即可使的平台4相对于底盘1降低或升高,同时与底盘1滑动连接的剪刀臂3会带动与之连接的齿条5向相应方向运动,在底盘1上设置卡扣6,卡扣6处于单向锁定状态时,依靠弹性力与齿条5保持接触,允许剪刀叉机构2带动平台4远离底盘1,即仅允许剪刀叉机构2带动平台4相对于底盘1升高,亦即仅允许齿条5向相应于平台4相对于底盘1升高的方向运动,而不能够反向运动,以此能够锁定平台4仅能够向相对于底盘1升高的方向运动,从而可有效防止平台4从高处跌落,具有较高的安全性。
对于上述实施例公开的升降平台,领域内技术人员还可以理解的是,可以人为的向卡扣6施加作用力,使卡扣6克服弹性力动作,与齿条5分离,处于解锁状态,此时可允许剪刀叉机构2带动平台4靠近或远离底盘1,即允许即仅允许剪刀叉机构2带动平台4相对于底盘1降低或升高,亦即仅允许齿条5向相应于平台4相对于底盘1降低或升高的方向自由运动。
对于上述实施例公开的升降平台,领域内技术人员还可以理解的是,多是在平台4相对于底盘1降低时,设置卡扣6处于解锁状态,卡扣6以及齿条5的具体尺寸结构,可由相关技术人员在应用本身请公开的技术方案时,根据具体实际进行选择或设计,在此不再做进一步的描述、限定。
在一些可选的实施例中,上述的升降平台中,齿条5及其对应的卡扣6有两个,每个齿条5对应与一个与底盘1滑动连接的剪刀臂3连接,以使升降平台动作平稳,增强安全性。
在一些可选的实施例中,上述的升降平台中,还包括:
偏心拨杆7;
电机8,在底盘1上设置,与偏心拨杆7连接,以能够驱动偏心拨杆7运动,使偏心拨杆7与卡扣6接触,克服弹性力带动卡扣6动作,使卡扣6与齿条5分离处于解锁状态。
对于上述实施例公开的升降平台,领域内技术人员可以理解的是,在需要平台4相对于底盘1降低时,可启动电机8驱动偏心拨杆7运动,使偏心拨杆7与卡扣6接触,克服弹性力带动卡扣6动作,使卡扣6与齿条5分离处于解锁状态;在需要平台4相对于底盘1升高时,可启动电机8驱动偏心拨杆7反向运动,使偏心拨杆7与卡扣6分离,使卡扣6依靠弹性力恢复至与齿条5保持接触的单向锁定状态。
在一些可选的实施例中,上述的升降平台中,还包括:
离合器9,在偏心拨杆7、电机8之间设置。
对于上述实施例公开的升降平台,领域内技术人员可以理解的是,在需要平台4相对于底盘1降低,卡扣6与齿条5分离处于解锁状态时,若剪刀叉机构2的驱动机构失效,平台4会急速跌落,由此引发安全事故,在偏心拨杆7、电机8之间设置离合器9,可在剪刀叉机构2的驱动机构发生失效时,断开偏心拨杆7、电机8之间的连接,使卡扣6依靠弹性力迅速恢复至与齿条5保持接触的单向锁定状态,从而能够快速的将平台4的高度锁定,制止住平台4跌落,以此避免安全事故的发生。
在一些可选的实施例中,上述的升降平台中,还包括:
安装座10,与底盘1连接;电机8设置在安装座10上。
在一些可选的实施例中,上述的升降平台中,还包括:
驱动机构,与剪刀叉机构2连接,以能够驱动剪刀叉机构2动作,带动平台4靠近或远离底盘1。
在一些可选的实施例中,上述的升降平台中,驱动机构包括:
两组液压作动筒11,其中,
一组液压作动筒11与底盘1连接,以及与剪刀叉机构2上靠近底盘1的支撑杆14连接;
另一组液压作动筒11与平台4连接,以及与剪刀叉机构2上靠近平台4的支撑杆14连接。
对于上述实施例公开的升降平台,领域内技术人员可以理解的是,其设置两组液压作动筒11分别与底盘1、平台4连接,可从两端同时对剪刀叉机构2进行驱动,使剪刀叉机构2动作平稳。
在一些可选的实施例中,上述的升降平台中,每组液压作动筒11中包括两个液压作动筒11。
在一些可选的实施例中,上述的升降平台中,还包括:
四个滚轮12,在底盘1上设置,具体可以是将四个麦克娜姆轮设置在底盘1上,驱动整个升降平台移动。
在一些可选的实施例中,上述的升降平台中,剪刀叉机构2的部件为机加件,以保证剪刀叉机构2的机械强度。
说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。
对于上述实施例公开的装置,由于其与上述实施例公开的方法相对应,描述的较为简单,具体相关之处可参见方法部分说明即可,其技术效果也可参考方法部分的技术效果,在此不再赘述。
至此,已经结合附图所示的优选实施方式描述了本申请的技术方案,领域内技术人员应该理解的是,本申请的保护范围显然不局限于这些具体实施方式,在不偏离本申请的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
