安装工艺规程Installationprocessprocedures
1轨道的安装Installationoftherail
1.1安装前的准备Preparationbeforeinstallation
1)熟悉规范、标准及图纸资料;Familiarspecifications,standardsanddrawings;
2)审查安装轨道所需材料的材质、规格、数量是否满足技术要求;Reviewwhetherthemounting-railmaterials’quality,specification,quantitymeetthetechnicalrequirements;
3)检查施工通道、清理现场,达到安全施工、文明施工要求;Checkthechannelsofconstruction,cleanupthesite,whichcanreachtherequirementsofsafeconstructionandcivilizedconstruction;
4)制定安全措施,设置安全生产区,有专人对高空作业及重物起升作业区进行监视,安全绳设置要有足够的强度及稳固性;Developsafetymeasures,setsafetyproductionarea,thereisspecialassignedpersonnelresponsibleformonitoringworkatheightandweightsliftingoperationareaandthesafetyropesetshouldhavesufficientstrengthandstability;
5)准备轨道安装所需用的机械、工具、量具;Preparerequiredmachinery,tools,measuringtoolsduringrailinstallation;
6)检查轨道的质量:
如发现有弯曲变形,应校正后才能安装;Checkthequalityoftherail:
iffoundbendinganddeformation,correctbeforeinstallation;
7)吊车梁放线检查及标高测量:

a用经纬仪测量吊车梁中心线,并留下标记(2—3米设置一个点);Thetheodoliteisusedtomeasurethecranebeamcenterlineandleavemarks(setapointevery2-3m);
b用水准仪测量吊车梁的水平标高,并作记录;Usewaterleveltomeasurethecranebeamandmakerecords;
C吊车梁跨距用钢卷尺、弹簧称测量;注意弹簧称的示值应和检查大车轮距时一致;Cranebeamspanshouldbedwithmeasuresteeltape,springbalance;payattentiontothespringbalanceshowedvaluesconsistentwiththoseduringmeasurementofthethreadofthegantry.
1.2轨道安装Railinstallation
1.2.1重轨(38kg/m以上)压板式安装程序(带钢垫板)Heavyrail(38kg/mormore)pressureplateinstallationprocedure(withsteelshim)
1)基准板安装1)Thereferenceboardisinstalled:
在吊车梁上每隔2米左右固定一块垫板,要求标高(用水准仪测量)控制在±2m以内,纵横向水平度以2mm/m水平仪找平;Onthecranebeam,fixapadaboutevery2m,requiredelevation(measuredwithwaterlevel)shouldbecontrolledwithin±2m,verticalandhorizontallevelnessshouldbemadewith2mm/mspiritlevel;
2)轨道就位2)Railinplace:
把经检查符合安装要求并下料的轨道按预选排好的顺序吊装就位;Hoistcutrailswhichmeettheinstallationrequirementsandafterinspectioninplaceaccordingtopre-determinedorder;
3)轨道找正、定位、紧固3)Railalignment,positioning,fastening
安装所用的工具、材料(螺栓、垫圈、压板、螺母等)用小桶或工具袋吊到吊车梁上,注意放好,以防掉下伤人;必要时也可对位穿好,但不紧固,用鱼尾板把轨道联接成一体,注意轨道接头应有2mm间隙,以保证热膨胀要求;根据中心线找正轨道,先固定基准位置,并测量检查安装数据,符合要求后,垫其它位置,要求垫平、垫实并固定,检查后把螺栓全部紧固。

4)测量检查4)Measurementandcheck:
轨道安装找正后,用经纬仪、水准仪、钢卷尺、弹簧称等量具进行最后测量检查,质量符合安装技术要求和设计要求,并做记录,作为交工资料。
Aftertherailmountingalignment,finalmeasurementandcheckshouldbemadewiththeodolite,level,steeltape,springbalanceequalamount,andthequalityshouldmeettheinstallationrequirementsanddesignrequirementsandmakerecordmakerecordswellwhichshallbeusedasthehandoverinformation.
5)质量检查符合要求后,将方垫圈与压板点焊,并每隔五组对焊一组。

1.2.2轻轨(24kg/m以下)、方钢轨道安装Installationoflightrail(24kg/morless)andsquaresteelrail
1)基准板安装1)Installationofthereferenceboard:
在吊车梁上每隔1.5米左右固定一块垫板,要求标高(用水准仪测量)控制在±2mm以内。
纵、横向水平度以2mm/m水平仪找平。

b焊接式安装:
在基准板位置进行找正,并点焊,待两条轨道所有基准板处都点焊完后,进行测量检查,符合要求后,进行复垫固定并点焊,最后进行全面焊接。
