苏制绞车断绳防坠器技术改造

Technical Transformation of Russian-made Winch Grip Block

断绳防坠器是竖井单绳提升罐笼最重要的安全保护装置。老式苏制绞车采用FS型断绳防坠器,自重大、结构复杂、维护运行费用高。对原有罐笼加以改造,将FS型断绳防坠器更换成BF型断绳防坠器。实践证明,BF型断绳防坠器比原苏制绞车的FS型断绳防坠器实用,值得推广。

Grip block is a most important safety protection device for cage hoisting with single rope in vertical shaft. The FS grip block is used by old type Russian -made winch. This grip block has some shortcomings, such as： the big deadweight, too complicated structure, the high maintenance and operation cost. The cage can be transformed by replacing FS grip block with BF grip block. Practice shows that BF grip block is more useful than the FS grip block of old type Russian -made winch, worth popularizing.
