According to the invention, the laser ranging sensor 34 is used for detecting the distance between the annular plate 33 and the outer wall of the cage guide steel wire rope 2, the detection result is fed back to the controller, the controller can judge the actual distance between the oil leakage sensor 35 and the outer wall of the cage guide steel wire rope 2 at the moment, and further control whether the hydraulic oil cylinder 32 acts or not so as to control the distance between the oil leakage sensor 35 and the outer wall of the cage guide steel wire rope 2. Because of having certain interval between oil leak sensor 35 and the 2 outer walls of cage guide wire rope, can guarantee that oil leak sensor 35 can not worn and torn.
Under the condition that the sliding sleeve 1 normally operates, the grease on the outer wall of the cage guide steel wire rope 2 only has a thin layer, and the oil leakage sensor 35 cannot detect the grease. When the oil leakage condition appears in the sliding sleeve 1, a part of grease can flow downwards along the inner wall of the sliding sleeve 1, a part of grease can flow downwards along the outer wall of the cage guide steel wire rope 2, the amount of grease flowing downwards along the outer wall of the cage guide steel wire rope 2 is greatly increased, and the thickness of the flowing grease can be increased at each time, so that the distance between the oil leakage sensor 35 and the outer wall of the cage guide steel wire rope 2 is set to be 3-10mm, the state of the grease can be effectively sensed when the oil leakage condition appears in the sliding sleeve 1, and further, a detection signal is fed back to.
