Rotating device between base hold and column is driving by electricity.Cross slider utilize reducer and Ball screw drive to control up and down. Beam front and back moving is driven by reducer motor and gear rack.Column and beam guide rails are the oversea imported heavy load straight guide. Beam both ends can be equipped with multifunctional and powerful abrasive wheel and belt,dust removal system while it is also considered to leave other grinding & gouge head interfaces. There is lift lugs beside column end which is a fixed type. Overhead head crane can lift without steel wire.Cross sliders are installed with dust protection unit.Staircases are provided on column for maintenance.The deflection can be removed by grinding & gouge head constant pressure relocation mechanism.Main technical DataMinimum height of Grinding & gouge head to ground ---------------------------------------800mmMaximum Height ---------------------------------------------5000 mmVertical moving maximum speed-------------------------------------100~1200mm /min(frequency control)Horizontal moving distance ---------------------------------------------5000 mmMaximum horizontal moving speed-------------------------------------100~1200mm /min(frequency control)Beam rotating degree allowed---------------------------------------------±90°column rotating available allowed---------------------------------------------±180°The beam deflection ---------------------------------------------2.5mm/mMultifunctional and powerful grinding wheel and belt headIt consists of left/right moving device, grinding & gouge head vertical rotating connection flange, grinding & gouge head horizontal rotation unit, grinding & gouge head side swing preventing unit, grinding & gouge head, grinding motor, welding seam abrasive wheel and grinding device, root pass powerful abrasive belt grinding device (abrasive belt contact wheel,tight and side swing preventing device ,), Pneumatic constant pressure relocation mechanism, automatic blade lifting unit and dust removal cover.Grinding & gouge head right/left horizontal moving unit consist of motor, special reducer, lateral small slide guide rail. The function of the right/left horizontal moving unit is to keep the grinding centerline coincides with the device center line after 90 degree rotating.Grinding & gouge head vertical rotating connection flange consist of motor reduction unit. The function is to facilitate the abrasive belt to parallel with welding seam surface while grinding the cladding welding seam.Grinding rotation unit consists of rotation ring and supporter. ±90 degree can be adjusted as vessel internal, external longitudinal/ circumferential seam conditions.Grinding & gouge head side swing lock preventing unit consist of lateral sliding device and related tight lock device. The abrasive wheel can automatically adjust the direction through sensor detection by following welding seam. The purpose is to avoid abrasive wheel blocked and dangerous occurs while the grinding direction deflection happens because the anti-floating roller without using. Tight lock device is to keep the abrasive grinding track no deflection.The whole grinding & gouge head and grinding belt are using same beam and motor system, consistent pressure relocation and automatic blade lifting system. The only difference is that the abrasive belt has separate wheel tight and side swing preventing device and covers.The abrasive belt can satisfy vessel internal and external grinding Gouge function technical dataMaximum gouge depth for weld ------------------------------------170mmMaximum gouge depth for one-pass gouge------------------------------------≤15mmMoving speed--------------------------------------1000mm/min (To avoid surface damage, we suggest to use small gouge blade to move fast to treat small pieces gouge Maximum gouge size of welding seam------------------------------------100×15mm(×)Maximum allowance for single time gouge------------------------------------≤100×5mmMoving speed while abrasive belt grinding--------------------------------350mm/minMaximum allowance for gouge cladding welding layer----------------------------------≥0.5mm/time ----------------------------------efficiency:10~20m/hMaximum tilt angle of welding seam bevel gouge abrasive belt------------------------10°Gouge surface quality Welding pass grind and gouge--------------------------------------------≤Ra6.3μmwelding root grind and gouge --------------------------------------------≤Ra12.5μmCladding welding layer grind and gouge -----------------------------------------≤Ra6.3~0.4μmbevel grind and gouge --------------------------------------------≤Ra6.3μmMultifunctional powerful lateral grinding & gouge headVertical rotating angle of grinding & gouge head -----------------------------------------0~90°Horizontal rotating angle of grinding & gouge head -----------------------------------------±90°Grinding & gouge head right/left moving distance -----------------------------------------±75mmside swing distance -----------------------------------------±50mmGrinding & gouge head blade lifting stroke-------------------------------------180mmConnection wheel size--------------------------------------------Φ300×100mmAbrasive belt size ---------------------------------------------100 ×2800mmAbrasive belt speed---------------------------------------------30m/sAbrasive wheel size ---------------------------------------------Φ650×12(12 ~ 22)mmMaximum Abrasive wheel grinding and gouge speed--------------------------------------65m/sgrinding and gouge power---------------------------------------------18.5kWGrinding & gouge head weight----------------------------------------------650kgDust remove systemDust removal system consists of industrial Wet vacuum cleaner, dust remove hose, suction inlet and related pipes. The features are big rate of flow, powerful negative pressure. Can be effectively used for removing metal powder, metal scrap, fibres, hazardous waste, and specially for the sparked metal scraps. It is equipped with spraying system, and also can be used for remove Inflammable and explosive dust. It can be used continuously. Long service time and lower maintenance cost. Hose between suction inlet and vacuum cleaner is made of refractory stainless steel hose.Technical DataPower----------------------------------------------------3.0KWair flow--------------------------------------------------------4000m3/h(Ptf)Pressure-------------------------------------------------2200paInlet diameter--------------------------------------------------Ф170mmOutlet diameter--------------------------------------------------Ф330mmPrecipitation tank volume ------------------------------------------------0.2 m3Dust removal efficiency----------------------------------------------------85%PLC control systemThe grinding and gouge machine utilizes Siemens PLC (S7-300) system. To make it easy to operate the machine, the transmitter cabinet control mainly depends on hand-held operation box control. Transmitter cabinet is located on the back of machine, each function grinding & gouge head and accessories are with separate fast interface. Pneumatic unit: air source 0.4~0.8mpa, it is with oil-water separator. Elements are using SMC brand. Grinding/gouge head coordinate control is driven by continuous manual variable frequency. The consistent pressure relocation mechanism can remove the beam deflection during grinding and gouging, which means the abrasive wheel is always perpendicular to the axis of the vessel. Required Linear velocity of vessel roller is 0.1-3m/minute during grinding or gougingMain purchased part brandSNNameBrand1motorSGHB2reducerSGHB3bearingsNSK, Japan4Heavy duty linear guideAMT, Taiwan5ball screwAMT,Taiwan6pneumatic elementSMC,Japan7slewing bearingKorea8self-lubrication systemNanjing,China9low-voltage electrical componentsAIKS, Hong Kong10control cabinetSGHB11PLC frequency converterSiemens,Germany12sensorAIKS, Hong KongSpare part listNameSpecificationPurposeQuantityconnection wheelΦ300×100Welding seam and Inside and outside surface5Abrasive belt415um,198umWelding seam and Inside and outside surface20Abrasive wheelΦ650×12(20) ×Φ80 mmgouging20
