Feem ntau lifting machinery raug xwm txheej thiab lawv tiv thaiv
(1) hlua-tawm kev sib tsoo hlua hlua-tawm kev sib tsoo yog hais txog kev sib tsoo ntawm cov khoom hnyav poob los ntawm cov hlua khi hlua khi thiab ua rau cov neeg raug mob thiab puas tsuaj. Qhov laj thawj tseem ceeb ntawm txoj hlua- tawm kev sib tsoo yog txoj kev khi tsis zoo thiab cov txheej txheem ntawm cov khoom hnyav, ua rau cov khoom hnyav plam; Kev xaiv tsis raug ntawm lub lifting qhov chaw ntawm lub ntiajteb txawj nqus, ua rau eccentric lifting los yog cov khoom hnyav poob vim qhov chaw lifting tsis ruaj khov; lub load yog swayed los ntawm kev sib tsoo, kev cuam tshuam, kev co, thiab lwm yam, ua rau cov khoom hnyav poob.
(2) Hook-tawm kev sib tsoo Hook-tawm kev sib tsoo yog hais txog kev sib tsoo ntawm cov khoom hnyav poob los ntawm cov khoom hnyav, nqa hlua lossis cov cuab yeej nqa tshwj xeeb ntog tawm ntawm lub qhov ncauj. Qhov laj thawj tseem ceeb ntawm kev sib tsoo- tawm kev sib tsoo yog qhov tsis muaj qhov sib txuas ntawm tus nuv; tsis ua hauj lwm ntawm tus nuv guard tiv thaiv ntaus ntawv; Txoj kev lifting tsis raug thiab deformation ntawm lub qhov ncauj qhov ncauj ua rau qhov qhib kom loj heev.
(3) Rope-breaking accidents The main reasons for the breaking of the lifting rope are overloading and breaking the wire rope; failure of the lifting limit switch causes overwinding and breaking the wire rope; oblique lifting and oblique pulling cause the wire rope to be squeezed and cut; the wire rope is used for a long time without maintenance, resulting in fatigue deformation, wear and tear, etc., which reaches or exceeds the scrap standard and causes the wire rope to be used. The main reasons for the breaking of the lifting rope are that the lifting angle is too large>120 degrees, yog li ntawd qhov nro ntawm txoj hlua lifting tshaj qhov txwv tus nqi thiab so; Kev xaiv tsis raug ntawm lifting hlau hlua hom thiab specifications, los yog tseem siv cov hlua hlau uas tau mus txog cov txheej txheem seem los khi thiab nqa cov khoom hnyav, ua rau cov hlua nqa cov hlua tawg; tsis muaj kev tiv thaiv kev ntsuas xws li gaskets ntawm kev sib cuag ntawm txoj hlua nqa thiab cov khoom hnyav, ua rau cov ces kaum txiav cov hlua hlau thiab ua rau txoj hlua lifting tawg.
(4) Hook breaking accident Hook breaking accident yog hais txog kev sib tsoo ntawm cov khoom hnyav ntog vim kev sib tsoo. Qhov ua rau kev sib tsoo sib tsoo feem ntau yog qhov tsis xws ntawm cov khoom siv nuv. Tus nuv tau hnav ntev ntev thiab nws cov hlaws tau raug txo qis rau tus qauv seem, tab sis nws tseem siv los yog feem ntau overloaded, ua rau qaug zog tawg. Kev huam yuaj ntawm cov khoom hnyav poob los ntawm kev nqa tshuab feem ntau tshwm sim nyob rau hauv lub lifting mechanism cov khoom winding system. Ntxiv nrog rau txoj hlua derailment, nuv derailment, txoj hlua tawg thiab sib tsoo tawg, kev kho ntawm ob qho kawg ntawm txhua txoj hlua nqa hlua kuj tseem ceeb heev, xws li seb qhov txwv kev nyab xeeb ntawm cov hlua hlua ntawm lub nruas tuaj yeem lav tau ntau tshaj 2 lub voj voog, seb puas muaj qhov txo qis kev tiv thaiv, thiab seb lub phaj siab thaiv kev ruaj ntseg ntawm cov khoom siv puas ruaj ntseg thiab kev ruaj ntseg. Tsis tas li ntawd, cov xwm txheej uas cov hlua hlau tawm ntawm qhov zawj (tawm ntawm lub nruas hlua groove) los yog tawm ntawm lub log (tawm ntawm lub pulley) kuj yuav ua rau poob.
