Description

一种电梯滚动导靴
技术领域
本发明涉及电梯技术领域，具体地说是一种电梯用的滚动导靴。
背景技术
现有技术中，为了使电梯在运行时有较好的稳定性和平衡性，通常在电梯的顶部和底部分别安装导靴装置。导靴一般分为滚动导靴和滑动导靴，滚动导靴相对于滑动导靴能够提供更高质量的运行性能，可以应用在电梯轿厢侧导轨和对重侧导轨，可以同时应用，也可以分开应用。滚动导靴通常卡设在电梯的运行导轨上，对电梯的垂直上下运行起到导向和限制作用，使电梯在垂直方向运行时不会偏离导轨，减小摆动幅度。
电梯滚动导靴主要包括底板、滚轮、组件等，底板安装在电梯上下粱上，通过调节滚轮组件与导轨之间的受力关系，由于上、下粱导靴连接处所在的平面之间不能保证绝对的平行，通常采用垫电靴底座来达到各滚轮运行时，保持各滚轮轴心线之间的平行关系，此技术理论上是可以完成各滚轮轴心线的平行关系，实际上是无法做到。从而导致电梯运行时导靴与导轨之间的摩擦噪音大，滚轮磨损大，电梯运行舒适感差。
发明内容
本发明解决的技术问题是提供一种电梯滚动导靴，通过在主卡位挡板上设置调心轴，使电梯在运行时电梯导轨与轿厢无间隙配合运行，并且滚轮能够进行一定角度的自动调节。
为了解决上述技术问题，本实用新型采取以下技术方案：
一种电梯滚动导靴，包括底板和滚轮组件，底板上设有支撑柱，滚轮组件卡装在支撑柱上，所述滚轮组件包括滚轮、主卡位挡板和辅卡位挡板，滚轮通过锁紧螺杆与主卡位挡板、辅卡位挡板的上部连接锁紧，支撑柱下部设有固定通孔，该固定通孔具有大口端和小口端，该固定通孔的大口端内设有无油轴承；
主卡位挡板下部设有调心球珠和调心轴，调心轴一端与主卡位挡板固定连接，调心球珠固定在调心轴上；
主卡位挡板安装在固定通孔的大口端所在的支撑柱侧壁，调心球珠卡装入该固定通孔内的无油轴承中，并且该调心球珠与固定通孔内的无油轴承之间为过盈配合，辅卡位挡板装在通孔小口端所在的支撑柱侧壁，主卡位挡板下部的调心轴依次穿过通孔、辅卡位挡板后用螺母锁紧。
所述调心球珠的最大外径与固定通孔内的无油轴承的内径相等。
所述支撑柱上的固定通孔的小口端的端口内径大于调心轴的最大外径。
所述支撑柱上部安装有定位杆，该定位杆位于锁紧螺杆下方，该定位杆一端沿与锁紧螺杆垂直方向穿过支撑柱上部并用螺母锁紧，定位杆上套装有减震器，该减震器紧抵着主卡位挡板和辅卡位挡板一侧面。
所述减震器包括套装在定位杆上的套筒、弹簧和垫片，该套筒为一端封闭一端开口结构，垫片位于套筒开口端，该垫片的封闭端抵顶着主卡位挡板和辅卡位挡板侧面，定位杆上的螺母顶着垫片锁紧，该垫片与套筒开口端之间具有一间隙，该间隙在0.1～0.8毫米。
本发明通过在用于安装滚轮的主卡位挡板上设置调心轴及相应的调心球珠，并且在相应的支撑柱上设置相匹配的固定通孔，内设无油轴承使调心球珠与无油轴承为过盈配合，并且由于调心球珠是一个球珠体，调心球珠因此能够在无油轴承内进行一定的转动，使各滚轮的轴心平行度能够调节一定角度，调节角度一般小于0.3度，确保电梯运行时各滚轮的轴心线相互平行，保证电梯导轨与轿厢无间隙配合运行，提高电梯的安全性和舒适性，并且导靴配件的磨损小，有效降运行噪音。

具体实施方式
为了便于本领域技术人员的理解，下面结合附图对本发明作进一步的描述。
如附图1～4所示，本发明揭示了一种电梯滚动导靴，包括底板1和滚轮组件，底板1上设有支撑柱2，滚轮组件卡装在支撑柱2上，滚轮组件包括滚轮3、主卡位挡板4和辅卡位挡板5，滚轮3通过锁紧螺杆6与主卡位挡板4、辅卡位挡板5的上部连接锁紧，支撑柱2下部设有固定通孔7，该固定通孔7具有大口端71和小口端72，小口端72的端口直径小于大口端71的端口直径；大口端72内设有无油轴承，该无油轴承通常是嵌装在该大口端71内，并且该无油轴承的外径等于固定通孔7的大口端71的直径，主卡位挡板4下部设有调心球珠8和调心轴9，调心轴9一端与主卡位挡板4固定连接，调心球珠8固设在调心轴9上，主卡位挡板4安装在固定通孔7的大口端71所在的支撑柱2侧壁，调心球珠8卡装入固定通孔7内的无油轴承中，且该调心球珠8与无油轴承之间为过盈配合；辅卡位挡板5装在固定通孔7的小口端72所在的支撑柱2侧壁，主卡位挡板4下部的调心轴9依次穿过固定通孔7、辅卡位挡板5，然后在调心轴9上套上螺母10并锁紧。为了稳固的锁紧，还可在调心轴9上套上垫片，然后再旋上螺母进行锁紧，将辅卡位挡板、主卡位挡板一起锁在支撑柱上。由于调心球珠为一球珠，从而使得该调心球珠在固定通孔内的无油轴承中能够进行一定角度的转动，调心球珠安装在调心轴上，由于调心轴与主卡位挡板固定连接，并且辅卡位挡板通过调心轴与主卡位挡板固定连接，因此，当电梯运行晃动时，主卡位挡板受到牵拉，球珠体的调心球珠在固定通孔7内的无油轴承中内可进行一定角度的圆弧摆动，实现滚轮的轴心线的自动调整，确保各个滚轮的轴心线相互平行。
为了保证调心球珠与固定通孔7内的无油轴承为过盈配合，调心球珠8的最大外径与固定通孔7内的无油轴承的内径相等，确保调心球珠8卡装在无油轴承后实现过盈配合，并且不易出现过大的偏动现象。需要说明的是，在底板上设置三个支撑柱，及在三个支撑柱上均设置有一个滚轮，此为公知常识，在此不再详细赘述。而且本发明中，各个滚轮相应的支撑柱的安装结构一致。支撑柱与底板可为一体成型结构，在生产制造的时候直接成型成一体。
而且，在滚轮的装配上，在锁紧螺杆6与主卡位挡板4间可设置一套圈垫15，并且，同样在主卡位挡板4与辅卡位挡板5间的锁紧螺杆6上也可套上一套垫16和相应的垫片，使得滚轮的安装更加稳固，此为常规技术手段，在此不再详细赘述。
此外，支撑柱2上的固定通孔7的小口端72的端口内径约稍大于调心轴9的最大外径，保证调心轴不会晃动过大，保持整体的平稳性，而且通过调心轴的自我调整，也有效降低了噪音。
另外，在支撑柱2上部安装有定位杆11，该定位杆11位于用于安装滚轮3的锁紧螺杆6下方，该定位杆11一端沿与锁紧螺杆6垂直方向穿过支撑柱2上部并用螺母锁紧，定位杆11上套装有减震器，该减震器紧抵着主卡位挡板和辅卡位挡板一侧面。在定位杆11上套上垫片，以确保螺母更加稳固地锁紧，此为常识和常用技术手段，在此不再详细赘述。所述减震器包括套装在定位杆上的套筒12、弹簧13和垫片14，该套筒12为一端封闭一端开口结构，垫片14位于套筒12开口端，该垫片的封闭端抵顶着主卡位挡板和辅卡位挡板侧面，定位杆11上的螺母顶着垫片14锁紧，该垫片14与套筒12开口端之间具有一间隙，该间隙在0.1～0.8毫米，使得弹簧具有一定和运动行程。当电梯运行有晃动时，套筒在定位杆上运动，会受到定位杆上的垫片的限制，从而使弹簧一端被套筒封闭端顶住、另一端则被该垫片顶住，使得弹簧的运动行程受到限制，确保运行的平稳性。
本发明用主卡位挡板下部安装的调心球珠，并且通过该调心球珠在支撑柱的固定通孔内的无油轴承的转动，从而实现各个滚轮的轴心线的相互平行，并且整个安装和调试都更加简单方便，使电梯运行时，电梯导轨与轿厢无间隙配合运行。
需要说明的是，以上所述并非是对本发明技术方案的限定，在不脱离本发明的创造构思的前提下，任何显而易见的替换均在本发明的保护范围之内。
