Description

一种夹轨式无机房电梯救援装置及方法 技术领域
本发明涉及一种无机房电梯救援装置，特别是一种夹轨式无机房电梯救援装置及方法。
背景技术
无机房电梯发生故障后，可能会失去动力，这也就会导致其无法通过自身动力来驱动轿厢移动至适宜的位置，以便维修人员进行检修；为了将轿厢移动至合适的位置，现有的方式一般都是通过打开电梯的制动器，通过重力作用使得轿厢和对重发生自溜，以此来实现轿厢的移动；当轿厢和对重重量平衡无法发生自溜时，一般会在补偿链上加装配重，以此来打破平衡，使其发生自溜；由于补偿链是一根链子，这样就会增加配重与补偿链之间的夹持难度和安装难度，而且补偿链在轿厢和对重运动过程中会随之移动或者受到外界的影响发生晃动，容易使得配重发生脱落。另外，轿厢和对重在自溜的过程中，需要制动器来控制轿厢自溜的距离，操作比较麻烦，制动器的磨损也比较大。因此，现有的技术存在着操作麻烦和夹持不牢固的问题。
发明内容
本发明的目的在于，提供一种夹轨式无机房电梯救援装置及方法。本发明具有方便操作和有效提高夹持牢固性的特点。
本发明的技术方案：一种夹轨式无机房电梯救援装置，包括与轿厢导轨相配合的夹轨器，夹轨器下方设有电动葫芦，电动葫芦下方设有吊绳；所述夹轨器包括安装板，安装板侧壁上设有一个或多个呈上下分布的夹紧组件，夹紧组件的外侧设有提拉板，夹紧组件上还设有位于提拉板外侧的插销。
前述的一种夹轨式无机房电梯救援装置中，所述夹紧组件包括固定座，固定座上设有导轨夹槽，导轨夹槽两端分别设有第一夹紧凹槽和第二夹紧凹槽，第一夹紧凹槽内设有活动夹紧机构，第二夹紧凹槽内设有固定夹紧机构；所述提拉板与活动夹紧机构的位置相对应。
前述的一种夹轨式无机房电梯救援装置中，所述活动夹紧机构包括两根倾斜布置的滑轨，两根滑轨之间设有一组辊轴；还包括与辊轴相对应的钳块，钳块侧壁上设有限位杆，限位杆上设有与插销相配合的销孔；所述固定座的侧壁上还设有与钳块相配合的限位板，限位板上设有与限位杆相配合的滑槽。
前述的一种夹轨式无机房电梯救援装置中，所述钳块包括钳块本体，钳块本体一侧设有与滑轨相对应的倾斜面，钳块本体另一侧设有夹紧块。
前述的一种夹轨式无机房电梯救援装置中，所述倾斜面的倾斜角度α为5-8°。
前述的一种夹轨式无机房电梯救援装置中，所述第一夹紧凹槽的上端还设有与钳块相配合的限位柱。
前述的一种夹轨式无机房电梯救援装置中，所述固定夹紧机构包 括设置在第二夹紧凹槽内的固定夹紧片，固定夹紧片和第二夹紧凹槽之间经螺栓相连。
前述的一种夹轨式无机房电梯救援装置中，所述安装板上下两端设有吊装孔。
前述的一种夹轨式无机房电梯救援装置中，所述提拉板包括板体，板体上设有两个上下对称分布的L型开口；板体上还设有与限位杆相配合的通孔。

具体实施方式
下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。
实施例。一种夹轨式无机房电梯救援装置，构成如图1至图5所示，包括与轿厢导轨8相配合的夹轨器1，夹轨器1下方设有电动葫芦2，电动葫芦2下方设有吊绳3；所述夹轨器1包括安装板4，安装板4侧壁上设有一个或多个呈上下分布的夹紧组件5，夹紧组件5的外侧设有提拉板6，夹紧组件5上还设有位于提拉板6外侧的插销7。
所述夹紧组件5包括固定座501，固定座501上设有导轨夹槽502，导轨夹槽502两端分别设有第一夹紧凹槽503和第二夹紧凹槽 504，第一夹紧凹槽503内设有活动夹紧机构505，第二夹紧凹槽504内设有固定夹紧机构506；所述提拉板6与活动夹紧机构505的位置相对应。
所述活动夹紧机构505包括两根倾斜布置的滑轨507，两根滑轨507之间设有一组辊轴508；还包括与辊轴508相对应的钳块509，钳块509侧壁上设有限位杆510，限位杆510上设有与插销7相配合的销孔511；所述固定座501的侧壁上还设有与钳块509相配合的限位板512，限位板512上设有与限位杆510相配合的滑槽513。
所述钳块509包括钳块本体514，钳块本体514一侧设有与滑轨507相对应的倾斜面515，钳块本体514另一侧设有夹紧块516。
所述倾斜面515的倾斜角度α为5-8°。
所述第一夹紧凹槽503的上端还设有与钳块509相配合的限位柱517。
所述固定夹紧机构506包括设置在第二夹紧凹槽504内的固定夹紧片518，固定夹紧片518和第二夹紧凹槽504之间经螺栓519相连。
所述安装板4上下两端设有吊装孔401。
所述提拉板6包括板体601，板体601上设有两个上下对称分布的L型开口602；板体601上还设有与限位杆510相配合的通孔603。
一种夹轨式无机房电梯救援方法，利用提拉板提拉钳块来自身重力将夹轨器安装固定于电梯轿厢上方的轿厢导轨，通过吊绳将电动葫芦和轿架相连，最终经电动葫芦起吊电梯轿厢，完成救援。
提拉板位于限位板的外侧。
本发明的安装过程：将夹轨器放置在轿厢上方的轿厢导轨，导轨卡槽与轿厢导轨相配合，人工操作提拉板，带动提拉板上移，提拉板上移就会带动钳块上移，钳块上移使得夹紧块也会随之上移，导轨卡槽就会变窄，使得夹紧块和固定夹紧片与轿厢导轨相夹紧，随后将插销插入销孔内，完成提拉板的固定。
将电动葫芦安装在安装板的下端，吊绳与轿架顶部相连，开启电动葫芦，就能够带动轿架上移；与此同时，在轿架等部件的重力作用下，安装板会受到向下的重力，给予滑轨、辊轴等部件一个向下的力，这样就会使得导轨卡槽的宽度存在进一步缩小的趋势，即随着夹轨器所承载重力的增加，夹轨器在导轨上的夹紧力就会随之增加。
