国产盘形闸使用以来,按厂家给的计算公式算出的油压值整定,发现有些绞车的制动力矩不够,尤其对绳,问题更为突出。有的矿井甚至造成事故。对于一些必须实施二级制动的矿井,虽然实施了二级制动,但由于没有准确的整定数据与方法,制动减速度仍然不能保证符合《煤矿安全规程》的有关规定,直接威胁着提升设备的安全运转。本文对以上两个问题进行分析讨论。
Since the use of domestic disc brake, according to manufacturers to calculate the formula to calculate the hydraulic pressure setting, found that some winch braking torque is not enough, especially for the rope, the problem is more prominent. Some mines even caused accidents. For some mines that must implement second-class braking, although the second-level braking is implemented, the braking deceleration can not be guaranteed to comply with the relevant provisions of the “Coal Mine Safety Regulations” because there is no accurate setting data and methods, directly threatening the promotion Safe operation of equipment. This article analyzes and discusses the above two issues.
