Description
本发明涉及曳引机减震技术领域,尤其涉及一种电梯曳引机构减震装置。
现有的电梯中,一般通过曳引机牵引电梯轿厢的升降运动。在电梯曳引机的工作过程中,特别是牵引轿厢进行快速升降的过程中,电梯曳引机往往会产生震动,从而影响电梯运行的平稳性。为了解决这个问题,现在一般在电梯曳引机底部安装橡胶减震垫或减震弹簧来进行减震;但橡胶减震垫的承重能力较弱,无法用于重量较大的曳引机的减震,适用范围较小;减震弹簧在减震时自身会往复运动(跳动),减震效果不理想,且减震弹簧容易生锈失效,使用寿命较短。而且,当高速运行的电梯需要进行紧急制动时,由于曳引机上曳引轮的自身重力和钢丝绳的较大的牵引力,容易导致曳引机倾翻,影响曳引机的运行安全性,同时对于不同规格的曳引机需要制作专用的减震垫,造成了减震垫的单一性;同时,现代电梯中尺寸越大的曳引机其减震要求越高,现有的减震装置都只适用于单一规格的曳引机,造成资源浪费,现有减震装置在设计安装时位置固定,然而设计过程中安装位置与实际需要减震位置存在一定偏差,由于减震装置与曳引机底座之间连接位置固定,在实际安装过程中无法做出调整,其减震效果被大大折扣。因此,现有的减震装置存在着承重能力较弱、适用范围较小、减震效果不理想、使用寿命较短、适用单一性的问题。
例如中国专利CN205170123U公开了一种电梯曳引机的减震机构,包括若干减震橡胶件、用于支撑所述减震橡胶件的固定支架;所述减震橡胶件设置在所述固定支架上,所述减震橡胶件的对外部的压紧方向朝向需被减震的结构。通过上述结构,该实用新型所述的电梯曳引机的减震机构起到良好的减震效果,从而保护电梯曳引机,延长电梯曳引机的使用寿命。安装在竖板及第一基板上的减震橡胶件共同减小了电梯曳引机左右、前后方向的振动,安装在第一基板及第二基板上减震橡胶件共同防止曳引机的倾翻。但该专利中减震机构并未消除底座底部和承重梁顶部之间的力传递,在使用过程中一部分震动力通过底座底部传导至承重梁,减震效果并不明显;同时减震机构的安装位置单一,无法满足不同规格下的曳引机减震要求。又如中国专利CN203743298U公开了一
种电梯曳引机用减震装置;属于电梯减震设备技术领域;其技术要点包括底板,其中所述底板上方设有安装曳引机的安装板,在底板和安装板之间夹设有若干第一减震胶垫,在安装板边缘设有若干平衡弹簧,平衡弹簧两端分别与底板和安装板固定连接,在正常状态下,平衡弹簧处于拉伸状态;该实用新型旨在提供一种结构合理、维护方便且减震效果良好的电梯曳引机用减震装置;用于电梯曳引机的减震。但该专利中的减震装置起结构大,且只能使用过单一规格下的曳引机,无法通用,存在局限性大的问题。

作为本实施方式的进一步优选的,所述中间减震装置为曳引机构减震装置的第二减震屏障;该中间减震装置包括第一减震层31、中间减震层和第二减震层34;第一减震层31置于中间减震层顶部,且位于第一连接件的第一凹槽内,第二减震层34置于中间减震层底部;第一减震层31和第二减震层34均采用形同的减震结构,所述第一减震层31由上减震件、下减震件和连接减震件之间的支柱,支柱连接上减震件和下减震件的侧边,该支柱由橡胶材料制备;上减震件和下减震件均采用塑料一体成型,且减震件为镂空型减震件;第一减震层31垂直于第一连接件长度方向的截面的外形可为长方形、正方形或正梯形,可根据实际需要调整第一减震层31结构;所述中间减震层由阻尼器33和套装于阻尼器33的减震弹簧32构成,阻尼器33底部连接第二减震层34。
作为本实施方式的进一步优选的,所述第二连接件5为凹型减震装置,第二连接件5的两侧开有用于安装螺栓等固定件的连接孔,通过固定件将第二连接件5与承重梁6固定连接,第二连接件5长度方向平行于底座1侧边,且其长度与第一连接件长度一致;第二连接件5的前后两端为开口状态,第二连接件5顶部中间位置处开有第二凹槽,第二凹槽贯穿第二连接件5的前后两端,中间减震装置的第二减震层34置于第二凹槽内;第二连接件5的顶部两侧还设有安装板51,安装板51垂直于第二连接件5侧面。第二连接件5和中间减震装置之间通过移动机构4连接,中间减震装置通过移动机构4可在第一连接件和中间减震装置之间移动,中间减震装置的数量及位置根据实际曳引机对底座1受力情况作相应调整,可满足电梯中不同规格曳引机减震要求。所述移动机
构4由凹型板42、固定板41和移动件43构成;中间减震装置的第二减震层34贴合于凹型板42中的凹形部分,固定板41垂直于凹型板42的两侧,固定板41靠近第二连接件5的安装板51外部侧边位置处开有通孔,通孔内安装移动件43。所述移动件43由T型移动杆和螺母44构成,T型移动杆底部车有螺纹,其余部分进行打磨,所述螺母44通过螺纹安装于T型杆上,旋紧状态下的螺母44上表面紧贴于第三装置的安装板51底面;为避免在使用过程中第二凹槽表面和安装板51上平面受到外界损坏,第二凹槽表面和安装板51上平面均包裹有橡胶层,橡胶层采用高弹性橡胶。
现代电梯中尺寸越大的曳引机其减震要求越高,现有的减震装置都只适用于单一规格的曳引机,造成资源浪费,现有减震装置在设计安装时位置固定,然而设计过程中安装位置与实际需要减震位置存在一定偏差,由于减震装置与曳引机底座之间连接位置固定,在实际安装过程中无法做出调整,其减震效果被大大折扣。本实施方式中的减震装置可满足不同规格的曳引机,其中,由于中间减震装置底部安装有移动机构4,其中间减震装置可通过移动机构4在第一连接件和第二连接件5之间移动,因此,中间减震装置的安装位置可在实际使用过程中由安装人员调整,同时中间减震装置数量的调整可通过第一连接件和第二连接件5的开口端进行安装和卸下,方便中间减震装置的拆卸和维修。当需要移动中间减震装置时,松开螺母44,中间减震装置通过移动机构4在第二连接件5的第二凹槽中前后移动,直至到达指定位置;此时,旋紧螺母44,将螺母44上表面紧贴安装板51底面,固定移动机构4,保证在使用过程中中间减震装置发生蹿动现象。
实施例2
本实施方式中,为进一步提高减震装置的减震性能,可将中间减震层中的阻尼器33替换为汽车悬挂系统中的筒式减震器,筒式减震器采用汽车悬挂系统中常用的减震器,工作时,筒式减震器中的活塞杆带动活塞在工作缸筒中反复上下运动,使工作缸筒内的油液便反复地从一个腔经过不同的孔隙流入另一个腔内,通过孔壁与油液间的摩擦和油液分子间的内摩擦对震动形成阻尼力,使震动能量转化为油液热能,进行减震,抑制减震弹簧32的跳动。
实施例3
本实施例中,所述第一减震层31由上减震件、下减震件、连接减震件之间的支柱和减震块,支柱连接上减震件和下减震件的侧边,该支柱由橡胶材料制备;上减震件和下减震件均采用塑料一体成型,且减震件为镂空型减震件;减震块安装于上减震件和下减震件之间的中间位置,减震块采用高弹性橡胶,减震块的形状可根据实际使用情况作出相应调整;减震块与支柱对第一减震层起到双重减震作用,进一步提高整体减震装置的减震性能。
上述说明示出并描述了本发明的优选实施例,如前所述,应当理解本发明并非局限于本文所披露的形式,不应看作是对其他实施例的排除,而可用于各种其他组合、修改和环境,并能够在本文所述发明构想范围内,通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明的精神和范围,则都应在本发明所附权利要求的保护范围内。
