The sealing plate 310 is provided with a stepped hole, and the connecting screw is rotated in the stepped hole. The screw is in threaded connection with the cleaning cylinder 3. The rubber layers are arranged on the surfaces, in contact with the side walls of the mounting openings, of the sealing plates 310, and after the sealing plates 310 are mounted in the mounting openings, the sealing plates 310 can seal and seal the mounting openings. The sealing of the mounting opening by the closure plate 310 is well known in the art.
A heating pipe 302 is fixed inside the cleaning cylinder 3. In the process of removing the grease on the steel wire rope sample to be detected, the heating pipe 302 is used for heating the steel wire rope sample to be detected, so that the fluidity of the grease on the steel wire rope sample to be detected can be improved, and the removal efficiency of the grease on the steel wire rope sample to be detected is further improved.
When the oil content of the steel wire rope sample is detected, a rotary joint on the water inlet pipe 306 is communicated with a supply pump of the degreasing solvent. The sealing plate 310 is opened, so that the steel wire rope sample to be detected is placed in the cleaning cylinder 3, two ends of the steel wire rope sample to be detected are placed on the bearing plates 409 at the left side and the right side, and the screw rods 407 at the left side and the right side are rotated through the knobs 408 at the left side and the right side, so that the screw rods 407 rotate downwards. The screw 407 drives the sliding plate 404 and the pressing plate 403 at one side of the screw to move downwards in the process of rotating downwards, and after the sliding plate 404 and the pressing plate 403 move downwards, the pressing plate 403 and the bearing plate 409 below the pressing plate clamp the end part of the steel wire rope sample to be detected.
The pressing plate 403 and the bearing plate 409 are provided with the salient points 410 on opposite end surfaces, the salient points 410 can increase friction force between the pressing plate 403 and the bearing plate 409 and between the end parts of the steel wire rope sample to be detected, and after the end parts of the steel wire rope sample to be detected are clamped by the pressing plate 403 and the bearing plate 409 on one side of the end parts of the steel wire rope sample to be detected, stability of the steel wire rope sample to be detected in the cleaning barrel 3 can be improved.
After the steel wire rope sample to be detected is clamped and stabilized in the cleaning cylinder 3, the sealing plate 310 is connected with the cleaning cylinder 3, and the mounting opening on the cleaning cylinder 3 is plugged by the sealing plate 310.
At this time, after the wire rope sample to be detected is held stable in the cleaning cylinder 3, the total mass a of the conductive member, the holding rotation means, and the wire rope sample to be detected is recorded by the pressure sensor 103.
Then, the motors 4 on the left and right sides are started, so that the motor 4 drives the rotating shaft 401 on one side to rotate in the direction opposite to the winding direction of the wire rope sample to be detected, and the wires forming the wire rope sample to be detected are dispersed. After the steel wires forming the steel wire rope sample to be detected are dispersed, grease in the steel wire rope sample to be detected can be conveniently and thoroughly removed. Then, the heating pipe 302 is started, and the heating pipe 302 is used for heating the steel wire rope sample to be detected. After the temperature of the steel wire rope sample to be detected is raised, the fluidity of grease on the steel wire rope sample to be detected is increased, so that the grease of the steel wire rope sample to be detected is convenient to separate.
After the heating pipe 302 heats the wire rope sample to be detected for a certain time, the heating pipe 302 is closed. The supply pump is started so that the degreasing solvent is sprayed through the high-pressure nozzle 308 to the wire rope sample to be tested after entering the water inlet pipe 306. And then simultaneously rotates the two motors 4 at a low speed in synchronization. When the first incomplete gear 309 and the second incomplete gear 411 are engaged, the second incomplete gear 411 drives the water inlet pipe 306 and the high pressure nozzle 308 to rotate through the first incomplete gear 309 as the rotation shaft 401 rotates. At this point the torsion spring on the inlet tube 306 holds up. When the second incomplete gear 411 is separated by the first incomplete gear 309, the water inlet pipe 306 and the high pressure nozzle 308 are rotated and restored by the elastic force of the torsion spring. In the process that the second complete gear rotates along with the rotating shaft 401 for one circle, under the action of intermittent meshing of the second incomplete gear 411 and the first incomplete gear 309 and the action of the elasticity of the torsion spring, the water inlet pipe 306 and the high-pressure nozzle 308 can reciprocally rotate in a certain angle, and in the process that the water inlet pipe 306 and the high-pressure nozzle 308 reciprocally rotate in a certain angle, the degreasing solvent discharged from the high-pressure nozzle 308 swings, the steel wire rope sample to be detected is flushed by the degreasing solvent, the impact effect of the degreasing solvent on the steel wire rope sample to be detected can be improved, and the grease on the steel wire rope sample to be detected can be quickly separated.
Grease on the wire rope sample to be detected is dissolved under the impact of the degreasing solvent and rapidly separated from the wire rope sample to be detected, and the grease and the degreasing solvent finally flow out of the cleaning cylinder 3 through the drain pipe 305. In the process of grease cleaning of the steel wire rope sample to be detected, the cleaning cylinder 3 can avoid splashing of the degreasing solvent, and the operation environment of the device can be prevented from being influenced by the degreasing solvent and the grease. The degreasing solvent and grease separated from the wire rope sample to be detected can be intensively discharged through the drain pipe 305, so that the degreasing solvent and grease can be intensively treated. Prevent the environment from being polluted by degreasing solvent and grease.
After the cleaning of the wire rope to be detected is completed, the water inlet pipe 306 is closed. The two motors 4 drive the steel wire ropes to be detected to rotate at the same direction and high speed, so that residual degreasing solvent on the steel wire ropes to be detected is separated from the steel wire ropes to be detected under the action of centrifugal force. The motor 4 is then turned off, and after the output shaft of the motor 4 is completely stopped, the grease and the degreasing solvent flow out of the cleaning cylinder 3 through the drain pipe 305. The total mass b of the conductive assembly, the clamping and rotating device and the wire rope sample to be tested at this time is recorded with a pressure sensor 103. And subtracting the mass b from the mass a to obtain the weight of grease in the steel wire rope sample to be detected, so that the oil content of the steel wire rope sample to be detected can be calculated.
