Description

电梯辅助安全装置 技术领域
本发明涉及升降机中检测、故障纠正或安全装置的应用，特别是涉及一种升降机防护装置。
背景技术
随着社会的进步，科技的发展，电梯的使用越来越普遍，随之而来的安全问题也日益凸显，电梯“吃人”的报道时常见诸报端。2016年3月，某地一位年轻母亲抱着五个多月大的女儿乘坐电梯，电梯门打开后，大人抱着小孩下意识的就往里边走，没想到电梯轿厢并未到达，导致母女双双跌入电梯井内当场身亡。时隔几日，电梯“吃人”的悲剧再次发生，某在建工地内，一名工人在施工中欲使用电梯，没想到电梯门开了轿厢却没到，工人一下子从一层坠入到约10米深的电梯井底，这名工人被送至医院后，最终因为伤情过重不幸身亡。在大众对乘坐电梯仍心有余悸时，又报道一名女士在电梯门打开后顺势迈进门内，不曾想这时电梯的轿厢并未到达，女士顺着电梯井从15层跌落，不幸当场死亡。还有某地小伙子喝高了，看电梯门没开，就直接踢门，结果门开了，电梯轿厢却没来，小伙子直接从4楼掉到1楼，万幸的是，他仅仅左腿骨折。同期还有某地一家商场的保安在巡查乘电梯时，电梯门开了，轿厢却没来，保安一脚踏空坠入电梯井负三层当场身受重伤。诸如此类的悲剧在世界上时有发生，给死伤者家属带来了极大的悲痛，同时死伤者的善后工作也成为电梯厂家及使用者沉重的经济负担。尽管现有电梯安全保障措施已十分完善，但电梯长期使用会导致部件损坏，性能变化，同时，监管检修不到位或其他偶然因素使电梯门打开与轿厢到达不同步，电梯门误开，极易造成人身伤亡。
发明内容
本发明要解决的技术问题是提供一种结构简单、价格低廉、使用方便、安全可靠、防护效果好的电梯辅助安全装置。
本发明电梯辅助安全装置，包括电梯井、轿厢、电梯门，在所述电梯门内侧沿纵向贴近所述电梯门设置一条柔性防护屏，在所述轿厢外侧的四个横向水平棱边处分别设置有导向装置，所述柔性防护屏的上屏布边固定在位于所述电梯井上方和/或下屏布边固定在位于所述电梯井下方的张紧装置上，所述柔性防护屏的中间屏布通过各个导向装置依次包覆所述轿厢的 上表面、背立面和底面。
本发明电梯辅助安全装置，其中所述导向装置包括位于所述轿厢上表面前棱边的第一导向装置、位于所述轿厢上表面和背立面交角处的第二导向装置、位于所述轿厢背立面与底面交角处的第三导向装置及位于所述轿厢底面前棱边的第四导向装置，所述第一导向装置、第二导向装置、第三导向装置和第四导向装置均为通过轴承座安装在轿厢上的滚轴。
本发明电梯辅助安全装置，其中所述张紧装置包括两个横向对称设置的静支座一、静支座二以及两根纵向平行设置在所述静支座一、静支座二上的导引滚轴和张紧滚轴，所述导引滚轴两端分别通过轴承支承在所述静支座一、静支座二上，所述张紧滚轴两端分别与动支座一、动支座二滚动配合，所述动支座一、动支座二分别沿纵向滑动地安装在所述静支座一、静支座二内，所述动支座一与静支座一之间、动支座二与静支座二之间分别通过压簧一、压簧二相互连接在一起，所述柔性防护屏依次绕过所述导引滚轴和张紧滚轴后，其上屏布边、下屏布边分别与中间屏布锚固在一起。
本发明电梯辅助安全装置，其中所述动支座一、动支座二上分别固定连接有销轴一、销轴二，所述销轴一伸入所述压簧内，所述销轴二伸入所述压簧二内。
本发明电梯辅助安全装置，其中所述柔性防护屏边缘处的厚度大于其他部位的厚度。
本发明电梯辅助安全装置，其中所述柔性防护屏由聚丙烯、聚乙烯、尼龙、化纤、碳纤维中的一种或几种制成。
本发明电梯辅助安全装置与现有技术不同之处在于，本发明电梯辅助安全装置是在电梯井内，在电梯门内侧紧贴电梯门自上至下设置一条张紧的柔性防护屏，防护屏通过导向装置从轿厢的外侧绕过，因此，防护屏在轿厢门之外的其他部位始终遮挡电梯门口，即使轿厢不到位，电梯门误开，乘客由于有防护屏的阻挡，也不会落入电梯井内造成人身伤亡，极大地提高了电梯使用的安全性。
下面结合附图对本发明的电梯辅助安全装置作进一步说明。

具体实施方式
如图1、图2所示，本发明电梯辅助安全装置包括电梯井1、轿厢2、电梯门3。在电梯门3内侧沿纵向贴近电梯门3设置一条柔性防护屏4，在轿厢2外侧的四个横向水平棱边处分别设置有导向装置100。本文所称的“纵向”是指电梯升、降的方向，“横向”是指电梯门3开、合的方向。柔性防护屏4的上屏布边41固定在位于电梯井1上方的张紧装置10上，下屏布边42固定在位于电梯井1下方的张紧装置10上。当然，张紧装置10也可以仅设置在电梯井1上方或下方，张紧装置10单独设置在上方时，上屏布边41固定在张紧装置10上，下屏布边42固定在电梯井1井壁上，张紧装置10单独设置在下方时，下屏布边42固定在张紧装置10上，上屏布边41固定在电梯井1井壁上，所以，上述张紧装置10可有3种布置方式。柔性防护屏4的中间屏布43通过各个导向装置100依次包覆轿厢2的上表面21、背立面22和底面23。结合图2、图3、图4和图5所示，导向装置100包括位于轿厢2上表面21前棱边的第一导向装置5、位于轿厢2上表面21和背立面22交角处的第二导向装置6、位于轿厢2背立面22与底面23交角处的第三导向装置7及位于轿厢2底面23前棱边的第四导向装置8，第一导向装置5、第二导向装置6、第三导向装置7和第四导向装置8均为通过轴承座91安装在轿厢2上的滚轴9。
如图6、图7所示，张紧装置10包括两个横向对称设置的静支座一101、静支座二101＇以及两根纵向平行设置在静支座一101、静支座二101＇上的导引滚轴105和张紧滚轴106，导引滚轴105两端分别通过轴承支承在静支座一101、静支座二101＇上，张紧滚轴106两端分别与动支座一11、动支座二11＇滚动配合，动支座一11、动支座二11＇分别滑动地安装在静支座一101、静支座二101＇内。动支座一11与静支座一101之间通过压簧一103相互连接在一起，动支座二11＇与静支座二101＇之间通过压簧二103＇相互连接在一起。结合图2、图8所示，对于布置在电梯井1下方的张紧装置10来说，柔性防护屏4依次绕过导引滚轴105和张紧滚轴106后，下屏布边42与中间屏布43锚固在一起。反之，对于布置在电梯井1上方的张紧装置10来说，柔性防护屏4依次绕过导引滚轴105和张紧滚轴106后，上屏布边41与中间屏布43锚固在一起。图8中以张紧装置10布置在下方为例，故下屏布边42与中间屏布43锚固在一起。采用锚固的固定方式操作简便、固定性能好。
如图6所示，动支座一11、动支座二11＇上分别固定连接有销轴一12、销轴二12＇，销轴一12伸入压簧103内，销轴二12＇伸入压簧二103＇内，设置销轴对压簧起到了良好的 导向作用，避免了压簧弯曲。
当然，为了实现张紧目的，上述张紧装置10也可以选用悬吊配重块的方式，例如，对于电梯井1上方的张紧装置10，可以在张紧滚轴106的两端分别悬吊一个配重块达到张紧目的。
如图4所示，为增强柔性防护屏4的抗拉强度和使用寿命，可将柔性防护屏4边缘处的厚度制作成大于其他部位的厚度。
本发明的柔性防护屏4可采用聚丙烯、聚乙烯、尼龙、化纤、碳纤维中的一种或几种制成，上述材料制成的织物耐磨损、抗拉强度大且造价低，用户可根据实际需求选用。
本发明的电梯辅助安全装置，在电梯门3内侧在电梯井1内自上至下紧贴电梯门3设置一条张紧的柔性防护屏4，即使当轿厢2未降至电梯门3处时，电梯门3误开时，由于柔性防护屏4的阻挡，乘客也不会踩空坠入电梯井1，避免了乘客坠入电梯井1这类安全事故的发生。同时，由于柔性防护屏4是包覆在轿厢2外侧，并未遮挡轿厢门，因此，轿厢2正常下降至电梯门3处，电梯门3打开时，用户可直接进入轿厢2。可见，本发明的电梯辅助安全装置安装时不需要更改电梯门3、轿厢2、电梯井1及其他电梯相关部件的现有结构，易于对现有的电梯进行升级改造。同时，本装置不含任何电控设备，其作业时也不需任何电控设备辅助，因而性能稳定，可靠性高。另外，柔性防护屏4还具有价格低廉、使用成本低的优点。
以上所述的实施例仅仅是对本发明的优选实施方式进行描述，并非对本发明的范围进行限定，在不脱离本发明设计精神的前提下，本领域普通技术人员对本发明的技术方案作出的各种变形和改进，均应落入本发明权利要求书确定的保护范围内。
工业实用性
本发明电梯辅助安全装置安装时不需要更改电梯门、轿厢、电梯井及其他电梯相关部件的现有结构，易于对现有的电梯进行升级改造。同时，本装置不含任何电控设备，其作业时也不需任何电控设备辅助，因而性能稳定，可靠性高，极大地提高了电梯使用的安全性，因此具有很大的市场前景和很强的工业实用性。
