Imported mining wire rope manufacturer: safety hazards of wire rope deformation

Imported mining steel wire rope manufacturers tell everyone that lifting galvanized steel wire ropes is a key component in the coal mine lifting stage. The damage to galvanized steel wire ropes is directly related to all normal production and manufacturing, the personal safety of workers, and the economic development and operation of coal mines. Manufacturers should attach great importance to it.

The deformation of galvanized steel wire rope explained by the editor of the imported mining steel wire rope manufacturer is usually caused by mechanical equipment damage, and in severe cases, it is harmful to the compressive strength of galvanized steel wire rope. Many safety accidents caused by rope breakage are due to the deformation and damage of galvanized steel wire rope in advance, which did not cause sufficient reproduction, resulting in great disasters.

1. Trauma: During the operation, the galvanized steel wire rope came into abnormal contact with other mechanical equipment. The obvious trauma was that the galvanized steel wire rope jumped out of the partition in the groove of the moving pulley and on the steel wire rope drum, causing damage to dozens or even hundreds of meters of galvanized steel wire rope due to local rolling.

2. Crushing: Galvanized steel wire ropes are prone to crushing after being rolled up on the steel wire rope drum. When the steel wire rope drum is rolled up, the galvanized steel wire ropes roll against each other, and the sound of "creaking, creaking, and creaking" is heard during actual operation. The damage to the galvanized steel wire rope caused by squeezing can quickly show signs of wire breakage and flattening in certain parts.

3. Knots: The long-term deformation caused by local twisting of galvanized steel wire rope is called a twisted galvanized steel wire rope. The twisted direction consistent with the rotation direction of galvanized steel wire rope is called a positive knot, and vice versa is called a negative knot.

Imported mining wire rope manufacturers tell you how to prevent deformation of galvanized wire ropes?

1. Trauma: The key to avoiding the trauma of galvanized steel wire rope is to improve mechanical equipment. The groove of the movable pulley should have a reliable ground anti slip groove flat washer, and the gap between the flat washer and the outer side of the movable pulley should not exceed 1/4 of the diameter of the galvanized steel wire rope. 5. The galvanized steel wire rope on the steel wire rope drum should not be too loose to prevent the rope loop from jumping out and damaging the partition when wrapped tightly.

2. Crushing: The countermeasure to avoid crushing is to choose the inclination angle of the moving pulley and steel wire rope drum according to the design standards. If necessary, a tensioner or steel wire rope compression device should be installed in the lifting mechanism to avoid disorderly winding of galvanized steel wire ropes.

3. Measures can be taken from the following three aspects

a. Non rotating galvanized steel wire ropes are used on critical lifting machinery.

B. Set the motor rotor (also known as the anti rotation device) at the optional end of the galvanized steel wire rope.

c. Improve the initiative of actual operators, immediately stop the actual operation and release it for recovery after discovering kinking symptoms.

The above is the safety hazards of wire rope deformation explained by the editor of imported mining wire rope manufacturers. I hope it can help everyone. Thank you for watching.
