我们在市场调查中发现,很多建材厂和选矿场使用的球磨机,在更换简体内的耐磨钢板时,其固定螺栓严重磨损、变形,造成固定螺栓拆除相当困难。作业人员拆除该固定螺栓时不但劳动强度大、效率低,还容易被金属碎片击伤。为了解决球磨机耐磨钢板固定螺栓拆除困难的问题,我公司研制开发出一种新型冲击作业工具一无后座力的液压式销轴冲击工具。1.结构及原理(1)结构无后座力液压式销轴冲击工具主要由操纵机构、执行机构和机体3个部件构成,如附图所
In our market research, we found that ball mills used by many building materials factories and processing plants have been severely worn and deformed when replacing the wear-resistant steel plates in the simplified ones, which has made the removal of fixing bolts quite difficult. When the worker demolishes the fixing bolt, the utility model not only has the advantages of high labor intensity, low efficiency, and is also easily bruised by metal fragments. In order to solve the ball mill wear plate fixing bolt removal difficult problem, our company developed a new type of impact tool a recoilless hydraulic pin impact tool. 1. Structure and principle (1) Structure No recoil hydraulic pin impact tool mainly by the operating mechanism, the implementing agencies and the body composed of three parts, as shown in the figure
