when the condition of the traction steel wire rope is detected to be normal by the method of the first embodiment, the traction steel wire rope can continue to work, the grease degree on the surface of the traction steel wire rope needs to be further judged, and the traction steel wire rope is prevented from being damaged due to the fact that the grease on the surface of the traction steel wire rope is reduced, so that the normal operation of an elevator car is influenced, and therefore the traction steel wire rope needs to be maintained in time;
specifically, when the first drive 14 drives the long plate 19 to contact with the traction steel wire rope, the traction steel wire rope can contact with the roller 23, the traction steel wire rope can drive the roller 23 to rotate, the rotation speed of the roller 23 is detected through the rotation speed sensor, a signal is transmitted to the control system, the condition of grease on the surface of the traction steel wire rope is judged, the rotation speed of the roller 23 is set to be b in the control system, wherein b is a limit distinguishing rotation speed value of the roller 23 between the surface of the traction steel wire rope with grease and the surface of the traction steel wire rope without grease;
because the surface of the roller 23 is a smooth structure, if grease on the surface of the traction steel wire rope is not consumed, the friction is small when the traction steel wire rope is in contact with the surface of the roller 23, so that the rotating speed of the roller 23 is slow, and if the grease on the surface of the traction steel wire rope is consumed, the surface of the traction steel wire rope is rough, so that when the traction steel wire rope is in contact with the surface of the roller 23, the rotating speed of the roller 23 is driven to be fast;
when the speed detector detects that the rotating speed of the roller 23 is less than b, the grease on the surface of the traction steel wire rope is proved to be not lost, the traction steel wire rope can normally work, and the maintenance is not needed;
when the speed detector detects that the rotating speed of the roller 23 is greater than b, the fact that grease on the surface of the traction steel wire rope is damaged is proved, the surface of the traction steel wire rope becomes rough, and at the moment, the control system controls the first driver 14 to drive the long plate 19 to return to the original position, so that the traction steel wire rope is convenient to maintain subsequently;
when the long plate 19 returns to the original position, the control system transmits a signal to the first pump body 16 to start the first pump body, external lubricating oil is pumped to the surface of the traction steel wire rope through the oil pipe 15, and then the control system controls the second drive 18 to drive the drive shaft 17 to rotate, so that the swing rod 12 is driven to rotate, the connecting strip 13 is driven to be close to the traction steel wire rope, when the traction steel wire rope moves, the traction steel wire rope with the lubricating oil passes through the connecting strip 13, the lubricating oil on the traction steel wire rope is uniformly coated through the coating strip on the connecting strip 13 at the moment, grease on the surface of the traction steel wire rope is increased, the surface of the traction steel wire rope is maintained, the abrasion of the traction steel wire rope is reduced, and the service life of the traction steel wire rope is prolonged.
