Problems solved by technology
The crane has a high probability of failure during operation, and the failure of the crane will seriously affect the normal production order
Due to illegal operation or when the hook descends and hits the object to generate an upward force, it often causes the fixed pulley wire rope of the crane to fall out of the groove
If the fixed pulley wire rope is not detected in time, it will cause abnormal excessive wear of the wire rope, or even a broken rope accident, which will increase the maintenance cost and workload of the equipment, cause great safety hazards to normal production and bring unnecessary troubles. Economic losses

The invention discloses a device for giving out an alarm when a steel wire rope gets out of a groove of a bridge crane fixed pulley. The device comprises a machine frame, a fixed pulley shaft, supports, a base, a travel switch and a limiting pull rod. The supports are perpendicularly arranged on the machine frame and are located at the two end of the fixed pulley shaft respectively. The base is arranged at the top ends of the supports. The travel switch is arranged on the end face of the base. The top end of the limiting pull rod is connected with an action end of the travel switch. The bottomend of the limiting pull rod horizontally extends to the position above the fixed pulley shaft. A contact of the travel switch is in signal connection with a controller of a bridge crane. The devicefor giving out an alarm when the steel wire rope gets out of the groove of the bridge crane fixed pulley timely gives out an alarm when the steel wire rope gets out of the groove, it is completely eradicated that abnormal excessive wear is caused to the steel wire rope or a broken rope accident occurs because the steel wire rope gets out of the groove, it is guaranteed that the crane works normally, potential safety hazards are avoided, and equipment overhaul cost and workload are reduced.
Description
technical field [0001] The invention relates to an alarm device for the steel wire rope of a fixed pulley of a bridge crane. Background technique [0002] Overhead crane (crane) is the main equipment for transporting materials in the production plant in the metallurgical industry. It has the characteristics of frequent work, high load operation rate and fast speed. The probability of failure of the crane during operation is relatively high, and the failure of the crane will seriously affect the normal production order. Due to illegal operation or when the hook descends and hits the object to generate an upward force, the fixed pulley wire rope of the crane is often caused to fall out of the groove. If the fixed pulley wire rope is not detected in time, it will cause abnormal excessive wear of the wire rope, or even a broken rope accident, which will increase the maintenance cost and workload of the equipment, cause great safety hazards to normal production and bring unneces...
