Description

升降设备 技术领域
本发明涉及高空作业技术领域，尤其涉及升降设备。
背景技术
为了在高空作业平台和初始平台之间输送人员、物资等，常使用升降机(升降设备)。升降机是通过提升机牵引以沿着悬挂在吊点上的工作钢丝绳进行上升或下降运动的设备。其中，升降机包括轿厢、电控箱、钢丝绳和地脚；升降机配有曳引主机，可以保证升降机在任意位置停止。电控箱位于轿厢内部，通过控制电控箱来控制电机的正转、反转和停止，从而控制升降机的运行。
现有升降机在上行和下行过程中，为了使其运行至指定位置(一般为停放升降机的初始平台位置和安装有触发板的升降机可运行的最高位置)，或者运行过程中触碰到运行通道中的障碍物时，可以及时停止运行，通常采用在轿厢上方和下方分别设置支架，在支架与轿厢之间分别设置多个控制开关件；当升降机运行至指定位置或遇到障碍物时，使得支架受到冲击力而向控制开关件方向移动并触发控制开关件，进而使得升降机停止运行，不仅避免因过度撞击而导致升降机内部的零部件发生损坏，而且还避免发生安全事故。
其中，上述升降机的支架受到冲击力而向控制开关件方向移动时，由于支架上设置的弹性件容易出现卡滞，使得支架无法继续移动，进而影响对控制开关件的准确触发。并且，由于曳引主机等位于轿厢顶板的外侧，进而其没有防护结构，且维修不便，需要设置专门的检修 窗，同时轿厢的通风也较差。

具体实施方式
下面结合附图和实施例对本发明的实施方式作进一步详细描述。以下实施例用于说明本发明，但不能用来限制本发明的范围。
在本发明实施例的描述中，需要说明的是，术语“中心”、“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明实施例的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本发明实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体连接；可以是机械连接，也可以是 电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明实施例中的具体含义。
在本发明实施例中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明实施例的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
请参见图1和图3，根据本发明实施例的升降设备，包括轿厢30、第一限位组件10、和第二限位组件40。其中，第一限位组件10包括位于轿厢30上方的顶板11以及第一控制开关件13，第一控制开关件13位于顶板11和轿厢30之间；第二限位组件40包括位于轿厢30下方的底板41、第三控制开关件43和下轮廓板42，第三控制开关件43位于底板41朝向下轮廓板42的一侧。其中，第二限位组件40还可以采用任何已经公开的结构形式替代，只要可以在轿厢下行过程中可以实现其限位即可。
当顶板11或下轮廓板42受到外力作用时，相应的向对应的控制开关件移动，以触发对应的控制开关件从常闭状态转换为常开状态，进而使得升降设备停止运行。
根据本发明实施例的升降设备，第一控制开关件13以常闭状态连接于升降设备的上行控制电路中，使得第一控制开关件13被触发后，会从常闭状态转换为常开状态，进而使得升降设备停止向上运行。其中，第一控制开关件13可以采用接触式控制开关或者非接触式控制开关实现。例如，接触式控制开关可以采用摆杆式行程开关等，非接触式控制开关可以采用超声波控制开关、红外线控制开关等。
优选地，将第一控制开关件13设置在相对于顶板11的中间位置，因为升降设备向上运行到指定位置(一般为安装有触发板的升降机可运行的最高位置)时，所触碰的该指定位置设置的触发板一般正对顶板11的中间位置，此时若顶板11的中间位置触碰到触发板，使得顶板因受到外力而向第一控制开关件13方向移动，以快速地触发第一控制开关件13从常闭状态转换为常开状态，使得第一控制开关件所接入的升降设备的上行控制电路处于断电状态，进而使得升降设备停止继续向上运行。
当顶板11受到外力作用后向第一控制开关件13移动，并触发第一控制开关件13后，升降设备因惯性原因会继续向上运行一段距离，此时顶板11会继续向第一控制开关件13移动，为了避免出现顶板11过度触发第一控制开关件13，而损坏第一控制开关件13，在设置第一控制开关件13的位置时，需要保证第一控制开关件13的触发面(第一控制开关件13设置触发结构(如摆杆)的上表面或非接触式触发的触发面)与顶板11之间的第一距离(单位mm)不小于1/10的单位时间(1s)所述升降设备的向上运行距离(升降设备运行速度mm/s，运行距离mm)。当第一控制开关件13为接触式控制开关时，顶板过度触发第一控制开关件13可以理解为顶板11过度触碰接触式控制开 关的触发结构，使得触发结构被迫挤压到接触式控制开关的顶面，从而损坏接触式控制开关。顶板过度触发第一控制开关件13还可以理解为顶板11移动至超过非接触式控制开关的触发距离，强力撞击非接触式控制开关，从而损坏非接触式控制开关。
在一个实施例中，请参见图2，顶板11通过多个弹性支撑组件12连接于轿厢30的顶部。其中，每个弹性支撑组件12包括回弹件121和支撑杆122，支撑杆122的一端设置有具有通孔的模具注塑件123，支撑杆122的另一端固定在轿厢30的顶部，回弹件121的一端固定在顶板上，回弹件121的另一端穿过模具注塑件123上的通孔，并可沿模具注塑件123上的通孔进行伸缩运动。其中，模具注塑件123的材质和结构不作限制，只需保证其上设置有供回弹件121穿过且方便回弹件121伸缩的通孔即可。
具体的，请参见图2，回弹件121包括导向杆(图中未标注)和套设在导向杆上的弹簧(图中未标注)，弹簧的两端对应抵在顶板11和模具注塑件123的相向面(顶板11的下表面和模具注塑件123的上表面)上，导向杆的一端固定在顶板11的下表面，导向杆的另一端穿过模具注塑件123上的通孔。其中，模具注塑件123上的通孔的尺寸与导向杆的尺寸相吻合，以保证导向杆可以沿着该通孔上下移动。
在一个实施例中，请参见图2，以在矩形顶板11的四个拐角位置分别设置一个弹性支撑组件12为例，当顶板11未受到外力时，顶板11在弹性支撑组件12的作用下维持在初始位置(弹性支撑组件12的弹簧处于自然状态时顶板所在的位置)。当顶板11受到外力时，顶板11相对第一控制开关件13运动，使得回弹件121的弹簧被压缩，同时回弹件121的导向杆沿着模具注塑件123上的通孔向下移动，带动顶板11同步向第一控制开关件13方向移动，以触发第一控制开关件13从常闭状态转换为常开状态，进而使得升降设备停止运行。当作用在顶板11上的外力被撤销时，顶板11在回弹件121的弹簧作用 下恢复至初始位置，此时第一控制开关件13恢复至常闭状态。需要强调的是，弹性支撑组件12数量和分布不受此处举例的限制，例如也可以对应顶板11的中心位置及边缘位置设置相应设置弹性支撑组件12，保证可以顶板11可以稳定的安装在轿厢30上方。
其中，在顶板11受到外力过程中，回弹件121不会卡滞在模具注塑件123上，进而保证顶板11在外力作用下可以向第一控制开关件13方向顺利移动，从而达到准确触发第一控制开关件13的目的。
在一个实施例中，为了实现顶板11任何位置受到外力作用时，顶板11相对第一控制开关件13运动都可以触发第一控制开关件13从常闭状态转换为常开状态，需要保证顶板11到模具注塑件123之间的距离不小于两倍的第一控制开关件13的触发面到顶板11之间的距离。
综上所述，本发明所提供的升降设备无需在轿厢30上方多个位置分别安装控制开关件，仅通过在轿厢30上方设置顶板11，并在轿厢30上方和顶板11之间设置一个第一控制开关件13即可满足对升降设备的控制需求，并且还减少了在轿厢30内单独设置多个对应于控制开关件的电控箱的数量，从而简化了升降设备的结构，便于安装和维护。其中，升降设备的控制需求是指升降设备向上运行至指定位置时及时停止向上运行，以及升降设备向上运行过程中其周围有障碍时及时停止向上运行。
此外，设置于轿厢30上方的顶板11其不仅可以对轿厢30形成防护，防止外部杂质落入到轿厢30内部；还可以对顶板11和轿厢30之间的相关部件形成防护，减少升降设备维修的次数。其中，顶板11的形状和材质不作限制，只需保证顶板11可以覆盖轿厢30顶部的面积即可。
在升降设备向上运行到指定位置的过程中，升降设备周围出现障碍或者升降设备到达指定位置时，为了防止因第一控制开关件13出 现异常，导致顶板11无法触发第一控制开关件13，进而使得升降设备继续向上运行，如图5所示，在一个实施例中，第一限位组件10还包括第二控制开关件14，第二控制开关件14位于顶板11和轿厢30之间，并且第二控制开关件14以常闭状态连接于升降设备的上行控制电路中。
第二控制开关件14作为备用控制开关件，当升降设备向上运行过程中，周围出现障碍或者升降设备到达指定位置需要触发第一控制开关件13，使得升降设备停止继续向上运行时，若第一控制开关件13出现异常，此时第二控制开关件14将被触发，即第二控制开关件14从常闭状态转换到常开状态，进而使得升降设备停止继续向上运行，以保证轿厢30中人员的安全，并保护轿厢30的结构(零部件的损坏)。
其中，第二控制开关件14的结构和第一控制开关件13的结构相同，在此不在赘述。
为了使顶板11受到外力作用时最先触发第一控制开关件13，当第一控制开关件13和第二控制开关件14采用接触式控制开关时，需要保证第二控制开关件14的触发结构(如摆杆)的上表面到第一控制开关件13的触发结构的上表面之间的第二距离不小于1/10的单位时间所述升降设备的运行距离。当第一控制开关件13和第二控制开关件14采用非接触式控制开关时，需要保证顶板11到第二控制开关件14触发位置(距离第二控制开关件14触发距离的位置)的第四距离大于顶板11到第一控制开关件13触发位置(距离第一控制开关件13触发距离的位置)的第五距离，并且两者之差不小于1/10的单位时间所述升降设备的向上运行距离。
在一个实施例中，第三控制开关件43以常闭状态连接于升降设备的下行控制电路中，使得第三控制开关件43被触发后，会从常闭状态转换为常开状态，进而使得升降设备停止向下运行。其中，第三 控制开关件43可以采用接触式控制开关或者非接触式控制开关实现。例如，接触式控制开关可以采用挂钩式行程开关等，非接触式控制开关可以采用超声波控制开关、红外线控制开关等。
请参见图3，当下轮廓板42受到外力作用后向第三控制开关件43移动，并触发第三控制开关件43后，升降设备因惯性原因会继续向下运行一段距离，此时下轮廓板42会继续向第三控制开关件43移动，为了避免出现下轮廓板42过度触发第三控制开关件43，而损坏第三控制开关件43，在设置第三控制开关件43的位置时，需要保证第三控制开关件43的触发面(第三控制开关件43设置触发结构(如摆杆)的触发面)与下轮廓板42之间的第三距离不小于1/3的单位时间(1s)所述升降设备的向下距离(升降设备运行速度mm/s，距离mm)。其中，顶板过度触发第一控制开关件13可以理解为下轮廓板42过度触碰接触式控制开关的触发结构，使得触发结构被迫挤压到接触式控制开关的顶面，从而损坏接触式控制开关。下轮廓板42过度触发第三控制开关件43还可以理解为下轮廓板42移动至超过非接触式控制开关的触发距离，强力撞击非接触式控制开关，从而损坏非接触式控制开关。
在一个实施例中，请参见图4，底板41与下轮廓板42四周通过柔性防护件45围合，形成安装第三控制开关件43的容纳空间。具体的，柔性防护件45顶端连接底板41，柔性防护件45底端连接下轮廓板42。当升降设备向下运行时，若遇到障碍或者到达初始平台位置，使得下轮廓板42受到外力作用而朝着底板41运动，此时柔性防护件45发生变形，使得下轮廓板42触发第三控制开关件43，使得第三控制开关件43从常闭状态转换为常开状态，进而使得升降设备停止继续向下运行。
在一个实施例中，柔性防护件45可以为防护布。此时从外部无法看到容纳空间内部的部件，进而既可以防护容纳空间中的部件，又 可以保证升降设备的视觉效果。当然，柔性防护件45还可以采用柔索或者其他具有柔性特质的结构。
在一个实施例中，为了实现下轮廓板42任何位置受到外力作用时，下轮廓板42相对第三控制开关件43运动都可以触发第三控制开关件43从常闭状态转换为常开状态，需要保证下轮廓板42到底板41之间的距离不小于两倍的第三控制开关件43的下表面到下轮廓板42之间的距离。
综上所述，本发明所提供的升降设备无需在轿厢30下方多个位置分别安装控制开关件，仅通过在轿厢30下方设置底板41和下轮廓板42，并在底板41和下轮廓板42之间设置一个第三控制开关件43即可满足对升降设备的控制需求，并且还减少了在轿厢30内单独设置多个对应于控制开关件的电控箱的数量，从而简化了升降设备的结构，便于安装和维护。其中，此处的升降设备的控制需求是指升降设备向下运行至指定位置时及时停止继续向下运行，以及升降设备向下运行过程中其周围有障碍时及时停止继续向下运行。
在一个实施例中，请参见图3，底板41背向轿厢30的一侧设置有地脚支撑44，以支撑升降设备脱离地面。地脚支撑44可以采用弯折板结构，以便于地脚支撑44的安装。其中，在下轮廓板42上设置有供相应地脚支撑44穿过的通孔(图中未标注)；地脚支撑44的数量至少为3个，只要保证轿厢30可以平稳放置在初始平台位置即可。例如，图3中，在底板41的拐角位置分别设置一个地脚支撑44。
此外，在下轮廓板42上还设置有供第三控制开关件43的控制线缆穿过的通孔(图中未标注)。将底板41通过围板安装至轿厢30底部，从而实现将第二限位组件安装至轿厢30上。
在一个实施例中，请参见图1，本发明所提供的升降设备还包括提升组件22，提升组件22设置在顶板11与轿厢30之间。进一步的，请参见图5和图6，提升组件22包括曳引主机27、提升板21、导绳 轮24和防尘罩26。曳引主机27位于轿厢30和顶板11之间，且适于驱动升降设备的升降。其中，提升板21数量为多块且相向设置；导绳轮24安装于与钢丝绳位置对应的两块提升板21之间；防尘罩26位于导绳轮24下方，且连接提升板21。防尘罩26可以避免导绳轮24外露至轿厢30内，使得导绳轮24及钢丝绳磨损产生的碎屑不能飘落到轿厢30内，保证作业人员的乘坐体验。其中，请参见图6，提升板21可以设置有曳引主机27、防坠安全器23以及导绳轮24等部件的安装孔，并且提升板21的数量可以依照各所需安装部件进行调整。此外，曳引主机的相关电气控制为现有成熟技术，在此不再赘述。
在一个实施例中，导绳轮24和提升板21可以一体安装，防尘罩26单独安装，进而可以方便防尘罩26的拆装，便于维护和安装。例如，防尘罩26可以通过可拆卸的方式安装于提升板21。其中，导绳轮24可以安装于轮轴，且轮轴两端固定于提升板21，进而保证导绳轮24受力稳定，保证升降设备可靠运行。
在一个实施例中，请进一步参见图5和图6，提升组件22还包括安装梁25，安装梁25固定于轿厢30顶部，提升板21固定于安装梁25。具体的，安装梁25采用L型横梁，且提升板21的两端分别与两根安装梁25连接。由此，如图7所示，轿厢30顶部形成敞口的结构，不仅可以保证轿厢30的通风效果，还可以便于提升组件22的维护。即不仅不需要额外再安装通风扇，而且也不需要在提升组件22与轿厢30顶部之间额外设置封口板和检修窗，工作人员可以直接从轿厢30顶部的敞口探出，以维修提升组件22的曳引主机27。
另外，在一个实施例中，参见图5和图6所示，当曳引主机27设置在相对轿厢30顶部的中间位置时，可以将第一控制开关件13和第二控制开关件14安装在曳引主机27所在平台上。
在一个实施例中，请参见图8，轿厢30包括滑动门31、电控箱 34以及分别与该滑动门31连接的左围板32和右围板33。其中，左围板32和右围板33均为L型围板，并且左围板32和右围板33通过铆钉连接，电控箱34安装至左围板32中上部，轿厢30顶部连接第一限位组件10，轿厢30底部连接第二限位组件40。具体的，轿厢30顶部通过安装梁25设置有提升板21、曳引主机27、导绳轮24、第一控制开关件13、第二控制开关件14和防坠安全器23等；轿厢30底部通过底板41设置有第三控制开关件43、柔性防护件45和下轮廓板42等。当然，轿厢30的结构不受此处举例的限制，任何现有技术公开的轿厢30都适用于本发明实施例中。
另外，图1和图7中，在轿厢30两侧设置有导向装置50，该导向装置50用于引导轿厢30两侧的钢丝绳运行，以减少升降设备运行时的晃动。其中，导向装置50为现有成熟技术，在此不在赘述。例如，常见的导向轮结构的导向装置。
以上实施方式仅用于说明本发明，而非对本发明的限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行各种组合、修改或者等同替换，都不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围中。
