门式起重机制动器调试
Brake adjustment of gantry crane
制动器的作用是在向机构发出停止运转的指令时制动器必须按要求及时将机构制动并保持不再运动。制动器调试是否合格直接影响到起重机的运行安全和人身安全。
The role of the brake is to stop the operation of the instructions issued to the agency when the brakes must be required in time to stop and stop the movement of the body. Whether or not the brake is tested directly affects the operation safety and personal safety of the crane.
如果升降机构制动器的制动力矩小或失灵,会导致溜钩,吊运物坠落可能引发设备事故和人身伤亡事故。震惊全国的07.4.18铁岭特钢公司钢水包倾覆特大事故,就与制动器末及时调整有关。
If the brake torque of the lifting mechanism is small or failure, it will lead to the sliding hook, and the falling of the lifting gear may lead to equipment accidents and personal injury accidents. Shocked the whole nation of Tieling Special Steel Company steel ladle overturning accident, with the brake at the end of the timely adjustment related.
如果两侧大车运行制动器的制动力矩不一致时,在停车时则会出现一侧被制动停止,而另一侧在惯性力的推动下继续前移,造成门架扭曲。而在两侧的制动器制动全无力时,则会发生溜车撞击现象,严重时可能造成事故。
If the brake torque of the two sides of the car running is inconsistent, when the brake is stopped, one side will be stopped, and the other side will continue to move forward under the inertia force, resulting in the distortion of the door frame. When the brakes on both sides of the brake is weak, there will be a car crash phenomenon, serious accidents may occur.
