重慶升降機(jī)卷筒開(kāi)裂的原因

來(lái)源:重慶和泰液壓升降機(jī)械廠 發(fā)布日期:2023-01-05 14:30:47

1、卷筒開(kāi)裂可能因?yàn)榻Y(jié)構(gòu)不合理,鋼板較薄,強(qiáng)度富裕度偏低,筒殼材質(zhì)較差,均采用鋼板。
Ningbo lifting platform roll cracking probably because of the irrational structure, steel thin, low intensity affluence, poor drum shell material, are used in steel.

2、升降平臺(tái)技術(shù)參數(shù)較低,而目前使用負(fù)荷都較滿(mǎn),甚至有些單位長(zhǎng)期超負(fù)荷使用。升降平臺(tái)的卷筒在循環(huán)應(yīng)力作用下產(chǎn)生疲勞裂紋,擴(kuò)展的結(jié)果就造成卷簡(jiǎn)鋼板或焊縫的開(kāi)裂。
Ningbo lifting platforms low technical parameters and load current use are relatively full, and even some units of long-term overload. Reel lifting platforms fatigue cracks under cyclic stress,the result of expansion and causing cracking or weld steel roll Jane.

3、升降平臺(tái)在使用時(shí)應(yīng)立即在裂紋端部打上止裂孔,將裂紋截住, 使其不再向前擴(kuò)展,然后進(jìn)行補(bǔ)焊和加固。最徹底的辦法是對(duì)升降平臺(tái)卷筒進(jìn)行技術(shù)改造,可將筒殼更換成新結(jié)構(gòu)的筒殼,或?qū)⒄麄€(gè)主軸裝置更換成新結(jié)構(gòu)的主軸裝置。
Ningbo lifting platform in use should immediately stop the crack tip marked hiatus, will crack stopped, it is no longer extended forward, then patching and reinforcement. The most thorough way is to roll lifting platform for technological innovation, you can replace the cartridge shell into a tube shell of the new structure, or to replace the entire spindle apparatus into the new structure of the spindle apparatus.
