遼寧橋式起重機打滑的原因及消除
The cause of the bridge crane skid and eliminate
遼寧橋式起重機打滑指車輪在輪道或地面上產生的有滑或在原地產生空轉現象。遼寧橋式起重機打滑一般發生在啟動或制動時。
Bridge crane skid refers to wheel on the wheel, or ground of slide or in situ have an idling phenomenon. Bridge crane skid generally happens at startup or when braking.
造成打滑的主要原因有電動機功率選擇過大，驅動力大于車輪與道軌間最大摩擦力；車輪輪壓??；制動器制動力矩過大，制動時間少于3~4s造成橋式起重機制動時打滑。
The main cause of skid have motor power to choose too large, driving force is greater than the maximum friction between wheels and rails; The wheel pressure small; The brake torque is too big, the braking time is less than 3 ~ 4 s cause of bridge crane brake skid.
消除遼寧橋式起重機打滑現象，首先必須分析產生打滑原因，根據不同原因采取相應措施。
Eliminate the phenomenon of bridge crane skid, first must analyze causes skid, take corresponding measures according to different reasons.
1 正確選擇橋式起重機匹配電動機，不宜過大
1 correct selection of bridge crane, matching motor shoulds not be too big
2 中確計算橋式起重機載荷能力和輪壓承載能力，保證車輪對車輪對軌面有足夠壓力。
2 is calculated carrying capacity of bridge crane load capacity and wheel pressure, guarantee the wheel to wheel to rail surface have enough pressure.
3 啟、制動時間適宜，一般小車啟動時間為4~6s，制動時間為3~4s。
3, braking time is appropriate, generally the car start time is 4 ~ 6 s, braking time is 3 ~ 4 s.
4 消除軌道霜雪、油污及積水以增加摩擦力。
4 eliminate orbit frost and snow, the oil and water in order to increase the friction.
