Description

Technical Field

[0001] The present invention relates to the technical field of wire rope detection, and particularly to a wire rope lubrication degree detection device. Background Art

[0002] During the processing and production of wire ropes, it is necessary to apply oil to their surfaces. Through capillary action, the liquid grease can penetrate deep into the wire rope core. At the same time, a micron-scale thin oil film is formed on the surface of the wire rope, which plays a role in protecting the external wire rope from corrosion and lubrication, and can also prevent moisture and water from entering the rope, significantly improving the overall quality of the wire rope.

[0003] In the prior art, a variety of wire rope lubrication degree detection methods and devices have been proposed. For example, a galvanized wire rope oil content detection method and an oil content control method proposed in the Chinese invention patent application with the publication number CN117030527A. The oil content detection method includes: obtaining a sample of the galvanized wire rope to be tested, splitting the sample of the galvanized wire rope to be tested into strand samples and core samples, and respectively weighing the weights of the strand samples and the core samples; repeatedly soaking and heating the strand samples and the dried core samples multiple times and then drying them, and weighing the weights of the dried strand samples and core samples; filtering the soaking solution of the strand samples to obtain filtered impurities, drying and cooling the filtered impurities, and weighing the weights of the filtered impurities; calculating the oil content of the sample of the galvanized wire rope to be tested based on the weights of the strand samples and core samples before and after the determination operation and the weight of the filtered impurities. Another example is a real-time wire rope lubrication system based on lubrication effect detection proposed in the Chinese utility model patent with the publication number CN213315902U. The system includes a centralized lubrication device. One end of the lubrication detection and oil distribution device is provided with a capillary oil pipe, and a lubrication effect detection device is provided at the root of the capillary oil pipe. The lubrication effect detection device and the centralized lubrication device are electrically connected to a control device. Through the elastic sheet connected to the root of the capillary oil pipe, the elastic sheet is connected to a tension sensor. When the wire rope moves, the wire rope will drive the capillary oil pipe in contact with it to move. According to whether the force on the elastic sheet at the root of the capillary oil pipe is uniform or not, the lubrication condition of the wire rope is judged. If the lubrication is insufficient and no lubrication layer is formed on the surface of the wire rope, the strands and cores of the wire rope will continuously move the capillary oil pipe, causing the elastic force of the elastic sheet to continuously change.

[0004] Since the lubricating oil of the wire rope penetrates from the outside to the inside, the distribution of the lubricating oil on the outside and inside of the wire rope is not uniform. However, the above detection methods and devices mainly detect the overall oil content and surface lubrication degree of the wire rope, and cannot detect the lubrication degree between the strands inside the wire rope, so the limitations are relatively large. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a wire rope lubricity detection device which can detect the lubricity of the entire surface of the wire rope and between the strands inside the wire rope, has few limitations and good versatility.

[0006] The invention discloses a wire rope lubricity detection device, comprising a base plate and a wire pulling mechanism, wherein the wire pulling mechanism is installed at the left end of the base plate and is used to drive the wire rope; the invention also comprises a main frame, a friction mechanism, an oil film detection mechanism, a clamping mechanism 1, a clamping mechanism 2 and a control box, wherein the main frame is installed at the middle of the base plate, the friction mechanism is installed at the right end of the base plate, the friction mechanism is used to detect the friction coefficient of the wire rope surface, the oil film detection mechanism is installed on the main frame, the oil film detection mechanism is used to detect the oil film thickness of the wire rope surface, the clamping mechanism 1 is installed at the right part of the main frame, the clamping mechanism 2 is installed at the right part of the main frame, and the clamping mechanism 3 is installed at the right part of the main frame. Installed on the left side of the main frame, the clamping mechanism 1 and the clamping mechanism 2 are used to clamp and twist the wire rope so that each wire strand of the wire rope is spread outward, and the control box is electrically connected with the friction mechanism, the oil film detection mechanism, the clamping mechanism 1, the clamping mechanism 2 and the rope pulling mechanism; when working, the rope pulling mechanism is a driving roller mechanism installed oppositely, and the wire rope passes between the two driving rollers of the rope pulling mechanism, and the wire rope passes through the clamping mechanism 1 and the clamping mechanism 2 and the wire rope is loosened, and the wire rope is installed in the friction mechanism, and the two driving rollers rotate to pull the wire rope to the left, so that the wire rope and the friction mechanism interact with each other. The friction is detected by the friction mechanism, thereby detecting the friction coefficient of the wire rope surface, and the lubricity of the wire rope surface is detected by comparing the detected friction coefficient with the friction coefficient of normal lubrication. At the same time, as the wire rope moves, the oil film detection mechanism detects the oil film thickness on the wire rope surface, and then detects the lubricity of the wire rope surface, and can determine the uniformity of the oil film on the wire rope surface; the wire rope is taken out of the friction mechanism, and the clamping mechanism 1 and the clamping mechanism 2 are operated to clamp the wire rope. The clamping mechanism 1 and the clamping mechanism 2 twist the wire rope against the spiral direction of the wire rope strand, and each wire rope strand of the wire rope is twisted. Loosen and open outward, the oil film detection mechanism moves left and right on the main frame, so that the oil film detection mechanism detects the oil film thickness on the surface of each opened steel wire strand, thereby obtaining the lubrication inside the wire rope. After the detection is completed, the clamping mechanism 1 and the clamping mechanism 2 are reversed and reset to make the steel wire strands of the wire rope retract and recover, and the clamping mechanism 1 and the clamping mechanism 2 loosen the wire rope, so that the wire rope continues to be pulled, and the subsequent part is detected. Compared with the existing technology, it can detect the overall surface of the wire rope and the lubrication between the strands inside the wire rope, with small limitations and good versatility.

[0007] Preferably, the friction mechanism includes a slide rail, a slide table, two first clamping plates, two screw rods, a distance measuring component and a spring. The slide rail is installed at the right end of the bottom plate. The slide table is slidably installed on the slide rail. One end of the spring is connected to the slide table, and the other end of the spring is connected to the slide rail. The two first clamping plates are respectively installed at the inner ends of the two screw rods. The two screw rods are respectively rotationally screwed on the slide table. The two first clamping plates are arranged oppositely. The distance measuring component is installed on the slide rail and the slide table. The distance measuring component is used to detect the displacement of the slide table on the slide rail; the distance measuring component is a grating ruler and a grating head or other distance measuring components. The steel wire rope is placed on the slide table. Rotating the two screw rods drives the two first clamping plates to be in frictional contact with the surface of the steel wire rope. When the steel wire rope is pulled leftward by the pulling rope mechanism, the frictional force between the steel wire rope and the two first clamping plates drives the slide table to slide leftward along the slide rail and stretches the spring to store energy. At this time, the frictional force between the steel wire rope and the first clamping plate is balanced with the elastic force of the spring. The distance measuring component detects the displacement amount between the slide table and the slide rail. When the displacement amount remains within a certain range, the lubrication degree of the surface of the steel wire rope is qualified. When the displacement amount exceeds the above range, the lubrication degree of the surface of the steel wire rope is unqualified, realizing the detection of the lubrication degree of the surface of the steel wire rope.

The film thickness detector is installed on the second slide table; the second slide table is driven by a driving mechanism. The second slide table drives the film thickness detector to move to detect the thickness of the oil film on the surface of the steel wire rope. The film thickness detector is an ultrasonic oil film thickness gauge or a vision detection system. When the film thickness detector is an ultrasonic oil film thickness gauge, the thickness is calculated by the reflection time difference of the sound wave at the interface between the oil film and the metal; when the film thickness detector is a vision detection system, an image of the reflectivity / wettability of the surface of the steel wire rope is obtained by shooting with a high-resolution camera, and the oil film thickness is judged through an AI algorithm; it belongs to the prior art and will not be elaborated too much.

A certain damping is provided between the sleeve and the mounting frame. When clamping the wire rope, the motor drives the gear to rotate. The gear meshes and drives the external gear ring to rotate, so that the plurality of second slopes of the external gear ring respectively move towards the guide slopes of the plurality of pressing rods, thereby squeezing the plurality of pressing rods inwards, making the plurality of second clamping plates approach and clamp the wire rope, realizing the clamping of the wire rope. At this time, the plurality of limiting blocks of the external gear ring are blocked by the plurality of blocking blocks of the sleeve. At this time, the motor continues to operate, making the external gear ring continue to rotate, so that the plurality of limiting blocks push the sleeve, the plurality of pressing rods and the plurality of second clamping plates to rotate through the plurality of blocking blocks, thereby twisting the wire rope, loosening and spreading out the plurality of wire strands of the wire rope. The motor drives the gear to reverse, making the external gear ring reverse, so that the plurality of second slopes of the external gear ring no longer squeeze the guide slopes of the plurality of pressing rods, unlocking the plurality of pressing rods, making the plurality of second clamping plates no longer clamp the wire rope, and the respective wire strands of the wire rope automatically recover under the action of their own elastic force; realizing the clamping of the wire rope and the spreading of the wire strands.

During operation, the weighing device weighs the wire rope carried on the main frame and records the initial weight. The heater and the blower are turned on to bake the part of the wire rope below the blower, so that the lubricating oil of the baked part evaporates or drips into the oil-absorbing cotton in the oil pan, removing the lubricating oil of the baked part of the wire rope. When the weight no longer decreases, the weighing device records the final weight. By calculating the difference between the initial weight and the final weight, the content of the lubricating oil on this part of the wire rope is obtained, and then whether the unit oil content of the wire rope is qualified is calculated, so as to judge whether the lubrication degree of the wire rope is qualified.

[0012] Preferably, it further includes two sliders and two middle pulleys. The two mounting brackets are respectively slidably and liftably mounted in the vertical slideways of the main frame through the two sliders. The middle pulleys are mounted on the main frame and are located below the fan. After the clamping mechanism I and the clamping mechanism II clamp the steel wire rope, the two sliders rise simultaneously, driving the two ends of the steel wire rope to rise, so that the middle part of the steel wire rope is blocked by the middle pulley, making the steel wire rope in a V shape. At this time, the fan and the heater are turned on to bake the V-shaped steel wire rope below, increasing the baking length of the steel wire rope and enabling the lubricating oil in the steel wire rope to better drip onto the oil receiving tray.

[0013] Preferably, it further includes two sponge rings.

[0030] Example 1, as Figures 1 to 10 shown, a wire rope lubrication degree detection device includes a bottom plate 1 and a rope pulling mechanism 2. The rope pulling mechanism 2 is installed at the left end of the bottom plate 1 and is used to drive the wire rope. It also includes a main frame 3, a friction mechanism 4, an oil film detection mechanism 5, a first clamping mechanism 6, a second clamping mechanism 7 and a control box 8. The main frame 3 is installed in the middle of the bottom plate 1, the friction mechanism 4 is installed at the right end of the bottom plate 1 and is used to detect the friction coefficient of the wire rope surface. The oil film detection mechanism 5 is installed on the main frame 3 and is used to detect the oil film thickness of the wire rope surface. The first clamping mechanism 6 is installed at the right part of the main frame 3, and the second clamping mechanism 7 is installed at the left part of the main frame 3. The first clamping mechanism 6 and the second clamping mechanism 7 are used to clamp and twist the wire rope to make each wire strand of the wire rope open outwards. The control box 8 is electrically connected to the friction mechanism 4, the oil film detection mechanism 5, the first clamping mechanism 6, the second clamping mechanism 7 and the rope pulling mechanism 2. The oil film detection mechanism 5 includes a second slide table 16 and a film thickness detector 17. The second slide table 16 is movably installed on the horizontal slideway of the main frame 3, and the film thickness detector 17 is installed on the second slide table 16. The structures of the first clamping mechanism 6 and the second clamping mechanism 7 are the same and are arranged opposite to each other left and right. The first clamping mechanism 6 includes a mounting frame 18, a plurality of pressure rods 19, a plurality of second clamping plates 20, an external gear ring 21, a motor 22, a gear 23 and a sleeve 35. The mounting frame 18 is installed on the main frame 3, the sleeve 35 is rotatably installed on the mounting frame 18, a plurality of jacks are arranged on the side wall of one end of the sleeve 35, and a plurality of pressure rods 19 are respectively slidably inserted into the plurality of jacks of the sleeve 35. Guide slopes are arranged at the outer ends of the plurality of pressure rods 19, and second clamping plates 20 are installed at the inner ends of the plurality of pressure rods 19. The external gear ring 21 is rotatably installed on the outer wall of the sleeve 35, a plurality of second slopes are arranged on the inner wall of the external gear ring 21, and the plurality of second slopes respectively match the plurality of guide slopes. A plurality of limit blocks are arranged on the inner wall of the external gear ring 21, and the plurality of limit blocks are respectively located between the plurality of second slopes. A plurality of stop blocks are arranged on the outer wall of the sleeve 35, and the plurality of stop blocks are used to block the plurality of limit blocks. The motor 22 is installed on the mounting frame 18, the gear 23 is installed on the output shaft of the motor 22, and the gear 23 meshes with the external gear ring 21.

[0031] During operation, the rope-pulling mechanism 2 is a driving roller mechanism installed opposite to each other. The wire rope passes between the two driving rollers of the rope-pulling mechanism 2, and then passes through the clamping mechanism 1 6 and the clamping mechanism 2 7 to loosen the wire rope. The wire rope is installed in the friction mechanism 4, and the two driving rollers rotate to pull the wire rope to the left, so that the wire rope and the friction mechanism 4 have relative friction, thereby detecting the friction coefficient on the surface of the wire rope. By comparing the detected friction coefficient with the friction coefficient of normal lubrication, the lubricity of the wire rope surface is detected. At the same time, as the wire rope moves, the oil film detection mechanism 5 detects the thickness of the oil film on the surface of the wire rope, and then the lubricity of the wire rope surface is detected, and the uniformity of the oil film on the surface of the wire rope can be determined; the wire rope is taken out of the friction mechanism 4, and the clamping mechanism 1 6 and the clamping mechanism 2 7 are operated to clamp the wire rope.

The film thickness detector 17 is an ultrasonic oil film thickness gauge or a visual detection system. When the film thickness detector 17 is an ultrasonic oil film thickness gauge, the thickness is calculated by the reflection time difference of the sound wave at the oil film and the metal interface; when the film thickness detector 17 is a visual detection system, a high-resolution camera is used to obtain an image of the reflectivity / wettability of the wire rope surface, and the oil film thickness is determined by an AI algorithm; it belongs to the prior art and will not be described in detail, thereby obtaining the lubricity inside the wire rope. After the detection is completed, the clamping mechanism 1 6 and the clamping mechanism 2 7 are reversed and reset to make the various wire strands of the wire rope gather and recover, and the clamping mechanism 1 6 and the clamping mechanism 2 7 loosen the wire rope, so that the wire rope continues to be pulled, and the subsequent parts are detected; compared with the prior art, it can detect the overall surface of the wire rope and the lubricity between the strands inside the wire rope;

[0032] The specific method for clamping and twisting the steel wire rope is as follows: A certain damping is provided between the sleeve 35 and the mounting bracket 18. When clamping the steel wire rope, the motor 22 drives the gear 23 to rotate. The gear 23 meshes and drives the outer gear ring 21 to rotate, causing the multiple second inclined surfaces of the outer gear ring 21 to move towards the guiding inclined surfaces of the multiple pressure rods 19 respectively, thereby squeezing the multiple pressure rods 19 inwards, causing the multiple second clamping plates 20 to approach and clamp the steel wire rope, achieving the clamping of the steel wire rope. At this time, the multiple limiting blocks of the outer gear ring 21 are blocked by the multiple blocking blocks of the sleeve 35. At this time, the motor 22 continues to operate, causing the outer gear ring 21 to continue to rotate, causing the multiple limiting blocks to push the sleeve 35, the multiple pressure rods 19, and the multiple second clamping plates 20 to rotate through the multiple blocking blocks, thereby twisting the steel wire rope, loosening and spreading out the multiple steel wire strands of the steel wire rope; the motor 22 drives the gear 23 to reverse, causing the outer gear ring 21 to reverse, causing the multiple second inclined surfaces of the outer gear ring 21 to no longer squeeze the guiding inclined surfaces of the multiple pressure rods 19, unlocking the multiple pressure rods 19, causing the multiple second clamping plates 20 to no longer clamp the steel wire rope, and the individual steel wire strands of the steel wire rope automatically recover under the action of their own elastic force; achieving the clamping of the steel wire rope and the spreading of the steel wire strands.

[0033] Embodiment 2, as Figures 1 to 3 、 Figure 11 shown, on the basis of Embodiment 1, the friction mechanism 4 includes a slide rail 9, a slide table 10, two first clamping plates 11, two screw rods 12, a distance measuring component 13, and a spring 36. The slide rail 9 is installed at the right end of the bottom plate 1. The slide table 10 is slidably installed on the slide rail 9. One end of the spring 36 is connected to the slide table 10, and the other end of the spring 36 is connected to the slide rail 9. The two first clamping plates 11 are respectively installed at the inner ends of the two screw rods 12. The two screw rods 12 are respectively rotationally screwed on the slide table 10. The two first clamping plates 11 are arranged oppositely. The distance measuring component 13 is installed on the slide rail 9 and the slide table 10. The distance measuring component 13 is used to detect the displacement of the slide table 10 on the slide rail 9; it further includes a bracket 14 and a marker 15. The marker 15 is installed on the slide table 10 through the bracket 14. The marker 15 is used to mark the steel wire rope. The marker 15 is electrically connected to the control box 8.

[0034] The distance measuring component 13 is a grating scale and a grating head or other distance measuring components. The steel wire rope is placed on the sliding table 10. Rotating the two screws 12 drives the two first clamping plates 11 to be in frictional contact with the surface of the steel wire rope. When the steel wire rope is pulled to the left by the rope pulling mechanism 2, the frictional force between the steel wire rope and the two first clamping plates 11 drives the sliding table 10 to slide to the left along the slide rail 9, and stretches and stores the elastic force of the spring 36. At this time, the frictional force between the steel wire rope and the first clamping plate 11 is balanced with the elastic force of the spring 36. The distance measuring component 13 detects the displacement between the sliding table 10 and the slide rail 9. When the displacement is within a certain range, the lubrication degree of the surface of the steel wire rope is qualified. When the displacement exceeds the above range, the lubrication degree of the surface of the steel wire rope is unqualified, realizing the detection of the lubrication degree of the surface of the steel wire rope. When the distance measuring component 13 detects that the displacement exceeds the set range, the control box 8 sends a signal to the marking device 15, and the marking device 15 operates to mark the steel wire rope below it. The marked position is the part where the lubrication degree of the surface of the steel wire rope is unqualified, which is convenient for supplementing lubricating oil to the marked part subsequently.

The middle pulley 29 is installed on the main frame 3, and the middle pulley 29 is located below the blower 25.

[0036] During operation, the weighing device 24 weighs the steel wire rope carried on the main frame 3 and records the initial weight. After the first clamping mechanism 6 and the second clamping mechanism 7 clamp the steel wire rope, the two sliders 28 rise simultaneously, driving the two ends of the steel wire rope to rise, so that the middle part of the steel wire rope is blocked by the middle pulley 29, making the steel wire rope in a V shape. At this time, the blower 25 and the heater 26 are turned on to bake the V-shaped steel wire rope below it, increasing the baking length of the steel wire rope, so that the lubricating oil on the baked part evaporates or drips into the oil-absorbing cotton in the oil receiving tray 27, removing the lubricating oil on the baked part of the steel wire rope. When the weight no longer decreases, the weighing device 24 records the final weight. By calculating the difference between the initial weight and the final weight, the content of the lubricating oil on this part of the steel wire rope is obtained, and then whether the unit oil content of the steel wire rope is qualified is calculated, so as to judge whether the lubrication degree of the steel wire rope is qualified.

[0038] When it is necessary to replenish lubricating oil in the middle of the sponge ring 30, the oil replenishing hole of the sleeve 35 is oriented towards the oil pot 34. The upper end of the capillary oil suction pipe 33 is inserted into the oil replenishing hole of the sleeve 35 and contacts the sponge ring 30. The lower end of the capillary oil suction pipe 33 extends into the lubricating oil in the oil pot 34, so that the lubricating oil in the oil pot 34 enters the sponge ring 30 along the capillary oil suction pipe 33 under the capillary action, thereby replenishing the oil for the sponge ring 30. When the wire rope moves in the two sleeves 35, the plurality of balls 32 roll along the grooves between the plurality of steel strands of the wire rope, thereby driving the inner rings of the two bearings 31 to rotate. The inner ends of the two bearings 31 respectively drive the two sponge rings 30 to rotate, so that when the wire rope passes through the two sponge rings 30, uniform oil replenishment is carried out, the lubrication degree of the surface of the wire rope is improved, or the lubrication degree of the wire rope after baking is restored.

[0039] Such as Figures 1 to 11As shown in the figure, a wire rope lubrication degree detection device of the present invention, when working, first the wire rope passes through between two driving rollers of the wire pulling mechanism 2, the wire rope passes through the clamping mechanism one 6 and the clamping mechanism two 7 and loosens the wire rope, the wire rope is placed on the sliding table 10, rotates two screws 12 to drive two clamping plates one 11 to frictionally contact the surface of the wire rope. After that, when the wire rope is pulled to the left by the wire pulling mechanism 2, the frictional force between the wire rope and the two clamping plates one 11 drives the sliding table 10 to slide to the left along the slide rail 9 and stretches the spring 36 to store energy. At this time, the frictional force between the wire rope and the clamping plate one 11 is balanced with the elastic force of the spring 36. The distance measuring component 13 detects the displacement between the sliding table 10 and the slide rail 9. When the displacement is maintained within a certain range, the lubrication degree of the wire rope surface is qualified. When the displacement exceeds the above range, the lubrication degree of the wire rope surface is unqualified. At the same time, the sliding table two 16 drives the film thickness detector 17 to move to detect the oil film thickness on the surface of the wire rope. Then take out the wire rope from the two clamping plates one 11, operate the clamping mechanism one 6 and the clamping mechanism two 7 to clamp the wire rope, the clamping mechanism one 6 and the clamping mechanism two 7 twist the wire rope against the spiral direction of the wire strands, loosen and open the respective wire strands of the wire rope, the sliding table two 16 drives the film thickness detector 17 to move, so that the film thickness detector 17 detects the oil film thickness on the surface of the opened respective wire strands, thereby obtaining the lubrication degree inside the wire rope. After the detection is completed, the clamping mechanism one 6 and the clamping mechanism two 7 reverse and reset to make the respective wire strands of the wire rope close and restore, the clamping mechanism one 6 and the clamping mechanism two 7 loosen the wire rope, and the wire rope continues to be pulled. Finally, the sponge ring 30 is infiltrated with lubricating oil, so that when the wire rope passes through the two sponge rings 30, oil replenishment is carried out to improve the lubrication degree of the wire rope surface.

[0040] The main functions achieved by the present invention are:

[0041] 1. It can detect the lubrication degree of the overall surface of the wire rope and between the strands inside the wire rope, with small limitations and good versatility;

[0042] 2. By detecting the friction coefficient on the surface of the wire rope, and comparing the detected friction coefficient with the friction coefficient of normal lubrication, the lubrication degree of the wire rope surface is detected;

[0043] 3. By detecting the oil film thickness on the surface of the wire rope, the lubrication degree of the wire rope surface is detected, and the uniformity of the oil film on the wire rope surface can be determined;

[0044] 4. By twisting the wire rope against the spiral direction of the wire strands, the respective wire strands of the wire rope are loosened and opened, and the oil film thickness on the surface of the opened respective wire strands is detected;

[0045] 5. Obtain the lubricating oil content on this part of the wire rope by calculating the difference between the initial weight and the final weight, and then calculate whether the unit oil content of the wire rope is qualified, so as to judge whether the lubrication degree of the wire rope is qualified.
