通过电器触点使电梯停止运行的管理办法1限速器一安全钳系统工作原理1speedlimiterisasafetyclampsystemprincipleofwork 限速器是限制电梯运行速度的装置,当轿厢上行或下行超速时,通过电器触点使电梯停止运行。当下行超速,电器触点动作仍不能使电梯停止,速度超过电梯额定速度115%以后,限速器机械动作,拉动安全钳夹住导轨将轿厢制停;当断绳造成轿厢或对重坠落时,也可由限速器的机械动作拉动安全钳,使轿厢制停在导轨上。限速器按动作原理可分为摆捶式和离心式两种,限速器一般安装在机房。安全钳按结构和工作原理分为瞬时安全钳和渐近式安全钳,安全钳一般安装在轿架的底梁,成对地同时作用在导轨上。Speedlimiteristorestricttheelevatorrunningspeedofthedevice,whenthecarspeedingupwardordownward,,ontactactionstillcannotmaketheliftstop,speedismorethan115%ofratedspeed,speedlimitermechanicalaction,pullthesafetyclampsliveguidewillcapsulestostop;Whenbrokenropecapsulesorheavyfall,canalsobepulledbythemechanicalactionofspeedlimitersafetyforceps,,,pliersandsecurityclampisgenerallyinstalledinthecaratthebottomofthebeam,inpairsandroleontheguiderail. 2限速器一安全钳系统检验中发现的问题2speedlimiterisasafetyclampsystemproblemsfoundduringtheinspection 在对限速器一安全钳系统的检验中,发现部分电梯由于维护保养不善,致使该安全装置根本达不到正常的工作要求,主要存在下列问题。Atthesafetygearforthespeedlimitersysteminspection,foundthatpartsoftheelevatorduetoimpropermaintenance,causethenormalworkofthesecuritydeviceyouneverevenasked,mainlyexistthefollowingproblems. (1)因限速器弹簧长期处于反复伸缩状态,使其整定动作速度改变。(1)becauseofthegovernorspringinrepeatedexpansionstateforalongtime,makeitssettingactionspeedchange. (2)转动部件长期缺油,阻力增大致使离心甩动部分动作不灵活。(2)themovingpartsarelong-termlackofoil,increaseresistancetothecentrifugalpartwasnotflexible. (3)由于钢丝绳自身的变化延伸,造成张紧装置触地,使钢丝绳张力不够,发生打滑。(3)duetothechangeofsteelwireropeitself,causingtensionertouchdown,wireropetensionisnotenough,skid. (4)安全钳的连杆拉臂传动部分缺油、锈蚀,致使提升力大大超过300N。Safetygear(4)thelinkarmdrivepartofthelackofoil,rust,theliftingforcemorethan300n.
