1.现有装置存在的问题我厂5万m~3煤气柜吊笼上的“过速检出”装置(以下简称“过速装置”)。是由马钢院参照宝钢煤气柜吊笼的过速装置而设计建造,至今无法使用。该装置工作原理大致如下(图1、图2):当卷筒7由电机带动转动时,大链轮1跟着转动并由链条带动小链轮2转动,再由它带大齿轮3转动。活动板13在小齿轮4同轴的轴端 P 与该轴滑动配合,但由予有一扭力弹簧(图中未画出)套在轴上,一端固定在轴上,另一端固定在活动板上,故若活动板13要转动必须克服弹
1. existing device problems I plant 50,000 m ~ 3 gas tank cage “over-speed detection” device (hereinafter referred to as “over-speed device”). It is designed and constructed by Masteel Institute against the overspeed device of Baosteel gas tank cage and has not been used up to now. The working principle of the device is as follows (Fig. 1 and Fig. 2): When the reel 7 is driven by the motor, the large sprocket 1 rotates and the small sprocket 2 rotates by the chain, and then rotates with the large gear 3. The movable plate 13 is slidably matched with the shaft at the axial end P of the pinion 4, but is provided with a torsion spring (not shown) on the shaft, one end of which is fixed on the shaft and the other end of the movable plate is fixed on the movable plate , So if the movable plate 13 to be rotated must overcome the bomb
