4.1.8在每次安装结束后及在使用中每三个月均应检查一次防坠安全器的动作情况,即对安全器进行坠落试验,坠落试验完后必须对安全器进行复位(见Makethefalling-testofsafedeviceafterinstallationeverytimeorevery3monthsbeingused;replaceitafterthetest(seethereplacementofthesafedevice)。4.1.8.1SAJ系列安全器使用说明书)ThenoteofthelimiterNotremovefreelytheleadsealingofthelimiter;b,使用,经修复或更换后方可继续使用。Ifthelimiterisoutoftheway(suchasthebrakingdistantistoolongorshortthewornpartsandso,stoprunninguntilrepairorinsteadanew。c应严格按照坠落试验周期进行坠落试验。Makethefalling-test。4.1.8.2坠落试验步骤Thestepofthefalling-testa坠落试验应在升降机完全处于工作状态下进行,且吊笼不允许载人;ThetestshallbedonewhenthehoistisundertheworkingcagecamannedThetestismadeontheground;thestretchthingismattedunderthecage;c升降机内均匀装载额定重量;Theratedweightisloadedinthehoist;dThetie-inofoneendofthebutton-caseisconnectedwiththetie-inoftheelectronicbox(seethechartoftheelectrictheory)。Takethespecialbutton-boxofthespeed-limitmachineoutofthecage;e关闭吊笼里、外笼门,合上外笼电源箱内的电源开关;Closetheinner-outerdoorofthecage;closethepowerswitchofthehandrailpower-box;f10m左Presstheascending-buttonontheoperating-case;drivethecageupabout10m1distantfromthehoistersbase;g按下坠落按钮,不要松手,吊笼向下坠落。当坠落速度达到限速器的额定动作速度(约1.2m/s)时,限速器立即动作,将吊笼制停在导轨架上;Pressthefalling-buttonandnotloose;thecagefallsdown;whenthefallingspeedreachestheratedlimitedspeed(about1.2m/s)thelimitermovesatonceandstopsthecageonthemastframe;h离)为0.3~1.2m;Thebrakingdistant(fromhearingthelimiterrunningtowherethecagestops)is0.3~1.2mnormally;i控制电路切断,如仍能动作,应重新调整微动开关;Startthecageanditwillrefusetorunbecauseofthesafedeviceisrunning;theswitchinthedevicehascutoffthe,ifornot,adjustit;j如果吊笼底部在距地面4m左右仍未停止,应立即松开坠落按钮,使吊笼制停在导轨架上,然后点动坠落按钮,使吊笼缓缓落在基础上,查明原因。Ifthecagedoesntstopat6mdistantfromthebaseduringthefree,thefalling-buttonisloosentokeepthecageonthemastthenthefalling-buttonispressedandthecagefallsonthemast。Findoutthereason。4.1.8.3限速器复位(图28)Thereplacementofthelimiter(dwg.28)4.1.8.3.1活动翻门进入吊笼;Whenthelimiterworkstokeepthecageonthemastframe,thetestpersonentersthecagefromthetopofthecage;b用专用工具(5)和摇杆(4)旋出螺母(7)的尾部和壳体Usespecifiedtool5andhandle4toscrewupnut7tothetailofpin6islevelwiththe2bodyofthelimiter(turnontheswitch);c安装螺钉(3)和罩盖(298然后用工具将螺栓()拧紧30°角后松开,装好罩盖(8)的方向与旋出螺母()的方向相同;Installnut3andcover;takedowncover;screwupbolts8tightlybyhand;thenusethespecialtooltoanglethebolt830°;installcover;screwupbolt8andmakeitatthesamedirectionofnut7。图28安全器的复位Drawing28Thereplacementofthesafedeviced200mm锥齿脱离复位,吊笼即可正常运行。Switchonthemainpower,immediatelystartupthecagetoabove200mm,whentherevolvingblockandgearareoutofreplacement,thehoistercanwork。3Theavoiding-fallingsafedeviceSAJ型防坠安全器是SC型施工升降机中的重要安全保护装置,它能限制吊笼超速运行,有效地防止吊笼坠落事故发生。当吊笼因故障引起失速下落时,防坠安全器开始动作并使制动力矩逐渐增加,在一定的距离内将吊笼平稳制动,从而保证了乘员的生命安全和设备的完好无损。SAJavoiding-fallingsafedeviceisanimportantprotectivedeviceforthehoister;itcanstopthecageexceedingrunningandpreventtheaccidentWhenthecageisfallingoutofcontrol,thelimitisswitchedonand'sbrakingmomentisincreasing;thecageisbrakedatthefixeddistant,soguaranteethesafetyoftheoperatorandequipment。5.1.11.1安全器结构(见图38Thestructureofsafedevice(dwg.38)Drawing38Thestructureofsafedevice1罩盖Cover2顶浮螺钉Bolt3螺钉Bolt4后盖Back5开关罩Switchcover6螺母Nut7Clamp8蝶形弹簧Spring9轴套Sheath10旋转制动毂Brakehub11甩块Revolvingblock12定位簧片Placereed13甩块座Revolving14轴套Sheath15齿轴Axis4ExampleforperformanceparameterDemarcatingspeed:accordingtotheconsumers说明:、升降机的总载荷(吊笼自Note:Totalofhoister(weightofcage+ratedload)≤safedeviceratedbreakingload、标定动作速度可根据用户需要的运行速度确定安全器的动作速度,即标定动作速度≤额定动作速度。Demarcatingspeedcouldconfirmthesafedevicesspeedaccordingtotheconsumers’requirementthatmeansdemarcatingspeed≤ratedspeed。SAJseriessafedeviceisunilateralprogressivetype,thebreakingdistanceisonthescutcheonWhenthecagerunningatnormalspeedthedevicealsomovesjiggleswitchison。Fixupthetopfloatingbolt,nopressureisbetweenscrewbreakingshellandoutsideshell,theblockisinretractconditionWhendoingfallingtestorotheraccidenttakeplace,thecagefallsdownexcessivespeedandreachthedemarcatingspeed,theblockwillbethrownoutjogglingwiththeratchetofscrewbreakingshell。Atthesameorientationalspringleafkeepstheblockinopeningstatewiththescontinuefallingdowngearandaxledrivethebreakingshellrunning,pushthetopfloatingbolt,twoshellscontactnutcompressthespring,switcharmdrivetheswitchtocutdownthe,thecagewillstopalongwiththeaddingoffrictionAfterknowingthereasonpress“safedevicereposition”toIfthedeviceworksuncertaintyorhasnoisestopimmediatelyandcontactwiththemanufacturerandthehoistermustntcontinueworkingnow。Note:safedevicemustbelubricatedtermly。SAJ运行时,安全器随动,微动开关处于接通状态。顶浮螺栓旋紧,旋转制动毂与外毂间无压力,甩块处于收回状态。当做坠落试验或由于意外原因,吊笼超速下降达标定速度时甩块甩出,与旋转制动毂上的棘齿啮合,同时定位簧片使甩块保持张开状态,随着吊笼5的继续下降,齿轴旋转带动旋转制动毂旋转,推开顶浮螺栓,两毂接触,螺母压缩碟簧开关压臂使开关动作切断电源,吊笼随摩擦力增大制停。查清原因后按“安全器复位”说明进行复位。如安全器动作不可靠、误动作或有异常噪声,应立即停机与生产厂家联Drawing39ThesafedeviceworkingprincipleWheninstalling,thejunctionboxofsafedeviceshouldbeatthebelowpositionandmustntbelaidoratupperposition。b安全器在储存、运输及使用过程中必须注意防水、防淋,以免影响使用。Duringthestorage,transportationandusingofsafedevice,consumersshouldpayattentiontoavoidwaterorrainsothatthemachinecouldworknormally。c每月二次向齿轮轴端油杯处注入润滑油,润滑脂牌号2Oilthegearaxleterminaloilcupmonthly,thelubricategreasemarkisNO.2c
