煤矿保安规程中规定,立井凿井时升降人员的吊桶的升降距离超过40米,必须沿钢丝绳罐道升降(装凿井吊盘后在吊盘下面不装罐道的部分也不得超过40米)。所以,吊桶稳绳是凿井工程的一项重要设施。 目前,在开凿暗井时,稳绳的悬吊通常用下列方式: l.以悬挂吊盘的钢丝绳作吊桶稳绳。 2.用链式手拉葫芦悬吊并做升降工具。 3.用稳车悬吊稳绳。 实用中,上述三种方法各有利弊,我们在暗立并施工时采用将吊桶稳绳集中放置在
Coal mine safety regulations stipulate that when the vertical shaft sinks, the lifting bucket of the elevator shall be more than 40 meters in height and must be lifted and lowered along the ropeway (the part not installed with a tank under the hanging plate shall not exceed 40 meters) . Therefore, the stability of the bucket bucket rope is an important facility sinking project. Currently, when digging a dark well, the steady rope suspension is usually used in the following ways: l hanging rope suspension rope for the bucket stable rope. 2. Chain chain hoists hanging and do lifting tools. 3. Steady suspension with stable car rope. Practical, the above three methods have their own advantages and disadvantages, we use the dark legislation and construction will be placed in the bucket stable rope concentrated
