Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator steel wire rope maintenance, in particular to a steel wire rope lubricating device for elevator maintenance. BACKGROUND

[0002] Steel wire rope is twisted by steel wire, and steel wire rope is used to drive the elevator up and down. In the process of long-term use, a large amount of rust will be generated on the surface of the steel wire rope, which will affect the normal use of the elevator. Therefore, the elevator steel wire rope needs to be regularly maintained and maintained. The maintenance content mainly includes lubricating the steel wire rope to avoid rusting. However, before lubricating the steel wire rope, the rust on the surface of the steel wire rope needs to be completely removed, and then oil can be sprayed on the surface of the steel wire rope. It is not allowed to directly apply oil on the surface of the steel wire rope with rust, which will further corrode the steel wire rope and cause safety hazards. The traditional rust removal method relies on manual rust removal, which is time-consuming and labor-intensive, and it is difficult to determine whether the rust on each section of the steel wire rope is completely removed. It is too dependent on manual work, and there is a lack of a device that can automatically remove rust from the surface of the steel wire rope while automatically judging the cleaning state of the surface of the steel wire rope according to the friction force of the surface of the steel wire rope, and then automatically switching the rust removal state and lubricating state of the rust removal plate, so as to ensure that the surface of the steel wire rope is completely cleaned without relying on manual work.

[0013] Compared with the prior art, the present application has the following advantages: In the present application, when the steel wire rope needs to be rusted, the first friction member and the second friction member are away from the steel wire rope in the initial state, the inner side of the second friction member is first controlled to contact the outer side of the steel wire rope, and in this process, the first rust removal plate and the second rust removal plate are respectively attached to the outer side of the steel wire rope by deflecting the second friction member, at this time, the steel wire rope is controlled to move from bottom to top, and the rust on the surface of the steel wire rope is scraped off by the contact between the steel wire rope and the rust removal end of the first rust removal plate and the second rust removal plate, and the scraped rust does not accumulate on the connecting plate.

[0014] In the present application, if the rust on the surface of the steel wire rope accumulates more, the initial scraping force of the first rust removal plate and the second rust removal plate is not enough, at this time, the second friction member is attached to the surface of the steel wire rope, when the rust on the surface of the steel wire rope accumulates too much, the friction force between the surface of the steel wire rope and the inner side of the second friction member is large, and during the movement of the steel wire rope from bottom to top, the second friction member is driven to move upward along the first friction member, and according to the accumulation degree of the rust on the surface of the steel wire rope, the friction coefficient between the steel wire rope and the inner side of the second friction member is directly affected, the more rust, the greater the friction force, under the cooperation of the booster assembly, the higher the second friction member rises, the closer the first rust removal plate and the second rust removal plate to the outer side of the steel wire rope, the greater the rust removal pressure applied to the steel wire rope, thereby realizing the effect of timely increasing or reducing the rust removal pressure on the surface of the steel wire rope according to the accumulation degree of the rust on the surface of the steel wire rope, and ensuring the effect of completely rusting the steel wire rope in all directions without manual control.

[0015] In the application, during the rust removal of the steel wire rope, the rust on the surface of the steel wire rope is more and thicker, and the friction resistance of the steel wire rope to the second friction piece is larger. With the continuous progress of the rust removal work, the friction force of the steel wire rope to the second friction piece gradually decreases. When the rust cleaning work is completed, the rust removal progress follow-up assembly, the deflection assembly and the sealing assembly drive the first rust removal plate and the second rust removal plate to deflect synchronously to the direction of the steel wire rope, and the gap generated by the deflection of the first rust removal plate and the second rust removal plate is shielded and sealed. At this time, the top of the first rust removal plate and the second rust removal plate is inclined, and the lubricating oil falling on the first rust removal plate and the second rust removal plate will flow to the direction of the steel wire rope when the lubricating device sprays lubricating oil on the surface of the steel wire rope to lubricate, and then gathers on the surface of the steel wire rope again, thereby avoiding the waste of lubricating oil caused by the accumulation of lubricating oil on the surface of the first rust removal plate and the second rust removal plate. And because the abutting portion of the first rust removal plate and the second rust removal plate is sealed, the lubricating oil will not drip down from the gap between the two, further avoiding the waste of lubricating oil.

[0023] The use method and advantages of the present application are as follows: a steel wire rope lubricating device for elevator maintenance, the working process is as follows: As shown in the embodiment, Figures 1 to 21As shown, during normal use of the elevator, the two mounting plates 1 are mounted at the elevator car, and the steel wire rope passes through the lubricating holes 2 between the two mounting plates 1, and the first rust removal plate 4 and the second rust removal plate 5 do not contact the steel wire rope. When maintenance of the device on the mounting plate 1 is required, the two mounting plates 1 can be disassembled by a screwdriver and removed from the elevator car for maintenance. When the steel wire rope needs to be rusted, in the initial state, the first friction piece 343 and the second friction piece 344 are away from the steel wire rope. First, the rotation connection points of the second connecting rod 325 and the third connecting rod 326 are pushed away from the second friction piece 344, driving the second connecting rod 325 and the third connecting rod 326 to deflect synchronously. At the same time of deflection, the first connecting rod 324 is disengaged from one of the first gear rods 322 and abuts against the other first gear rod 322, and the first spring 327 is compressed and re-extended, thereby driving the third connecting rod 326 to disengage from one of the second gear rods 323 and abut against the other second gear rod 323, thereby driving the first friction piece 343 and the second friction piece 344 to deflect to one side of the steel wire rope, and the inner side of the second friction piece 344 contacts the outer side of the steel wire rope. During this process, as the third connecting rod 326 deflects, the rotation connection point of the third connecting rod 326 and the connecting plate 321 rotates by a certain angle, driving the fourth connecting rod 331 to deflect. During the deflection process, the first gear wheel 332 and the second gear wheel 334 are in contact and disengaged, thereby driving the second gear wheel 334 and the third gear wheel 335 to rotate counterclockwise by a certain angle, thereby driving the first toothed slot rod 315 and one of the mounting blocks 313 connected thereto to slide a certain distance away from the connecting plate 321, and under the cooperation of the arc-shaped sliding groove 314, driving the driving disc 312 to rotate by a certain angle, thereby driving the two mounting blocks 313 to slide a certain distance synchronously toward the opposite side, so that the first rust removal plate 4 and the second rust removal plate 5 respectively abut against the outer side of the steel wire rope. At this time, the steel wire rope is controlled to start moving from bottom to top. As the steel wire rope contacts the rust removal end of the first rust removal plate 4 and the second rust removal plate 5, and because the bottom of the first rust removal plate 4 and the second rust removal plate 5 is tapered, the rust on the surface of the steel wire rope is scraped off, and the scraped rust does not accumulate on the connecting plate 321; If the rust on the surface of the steel wire rope accumulates more, the initial scraping force of the first rust removal plate 4 and the second rust removal plate 5 is not enough, at this time, due to the second friction piece 344 attached to the surface of the steel wire rope, the fourth gear 353 changes the matching position to move to the top of the second toothed groove rod 351 and pre-engages with the teeth at the lower part of the second toothed groove rod 351, and the fifth gear 354 engages with the third toothed groove rod 356, when the rust on the surface of the steel wire rope accumulates too much, the friction force between the surface of the steel wire rope and the inside of the second friction piece 344 is larger, during the process of the steel wire rope moving from bottom to top, it will drive the second friction piece 344 to move upwards along the first friction piece 343, and according to the accumulation degree of rust on the surface of the steel wire rope, it directly affects the friction coefficient between the steel wire rope and the inside of the second friction piece 344, the more rust, the greater the friction, when the rust accumulates to the extent that the first rust removal plate 4 and the second rust removal plate 5 cannot be cleaned completely, at this time, the second friction piece 344 rises to the state that the teeth at the bottom of the second toothed groove rod 351 engage with the fourth gear 353, at this time, with the continuous rising of the second friction piece 344, the fourth gear 353 and the fifth gear 354 are driven to rotate clockwise by the second toothed groove rod 351, and then the mounting block 313 is driven to continue to move in the direction of the steel wire rope under the action of the second connecting rod 355, the higher the second friction piece 344 rises, the closer the first rust removal plate 4 and the second rust removal plate 5 to the outside of the steel wire rope, the greater the rust removal pressure applied to the steel wire rope, thereby realizing the effect of timely increasing or reducing the rust removal pressure on the surface of the steel wire rope according to the degree of rust accumulation on the surface of the steel wire rope, thereby ensuring the effect of completely removing rust on the steel wire rope in all directions without manual control; In the process of rust removal of the steel wire rope, since the rust on the surface of the steel wire rope is thick, the frictional resistance of the steel wire rope to the second friction member 344 is large, driving the second friction member 344 to slide upward along the first friction member 343, and at this time, the fourth toothed groove rod 611 at the side end of the second friction member 344 is engaged with the sixth gear 613, with the rising of the second friction member 344, driving the sixth gear 613 to rotate, and then driving the fifth toothed groove rod 614 to descend, while descending, driving the sliding block 615 to descend inside the mounting cylinder 612 under the action of the connecting column 616, and the top of the grabbing member 617 is separated from the inclined surface at the top of the mounting cylinder 612, and when the second friction member 344 rises to the highest point, the bottom of the grabbing member 617 contacts the grabbing block 621 at the top of the lifting block 620, and under the action of the second spring 345, the grabbing block 621 is hooked, realizing the grabbing of the lifting block 620, with the continuous progress of the rust removal work, the rust on the surface of the steel wire rope gradually decreases, the friction between the steel wire rope and the surface of the second friction member 344 decreases, and the second friction member 344 gradually descends, and then drives the two grabbing members 617 to control the lifting block 620 in the grabbing state to rise, while the lifting block 620 rises, driving the sliding plate 632 and the fixed plate 633 to rise synchronously, at this time, the inclined surface at one side of the wedge-shaped block 634 contacts the inclined surface at the bottom of the tooth, driving the wedge-shaped block 634 to slide to the inside of the side end of the fixed plate 633, and then extending after being separated from the tooth, so as to realize the step-by-step rising of the fixed plate 633 without descending, when the rust on the surface of the steel wire rope is completely cleaned, at this time, there is no friction between the steel wire rope and the second friction member 344, so that the second friction member 344 descends to reset, and then drives the lifting block 620 to rise to the highest point inside the mounting cylinder 612, at this time, the first trigger block 635 at the side end of the fixed plate 633 contacts the second trigger block 636, and the two are extruded, driving the fixed plate 633 to slide a distance on the bottom of the sliding plate 632 to the direction close to the lifting block 620, under the action of the third connecting rod 641, driving the extrusion frame 642 to slide to the direction of the first rust removal plate 4, so that the bottom of one side of the extrusion frame 642 extrudes the end close to the second rust removal plate 5 of the first rust removal plate 4, driving the first rust removal plate 4 to deflect, with the deflection of the first rust removal plate 4, the pressing plate 657 deflects downward to press the extension end of the spring telescopic rod 652, and then drives the sixth toothed groove rod 653 to descend, under the action of the seventh gear 654, driving the seventh toothed groove rod 655 to slide to the direction close to the first rust removal plate 4, and then driving the sealing plate 656 to seal and shield the gap generated by the deflection of the first rust removal plate 4 and the second rust removal plate 5, at this time, the top of the first rust removal plate 4 and the second rust removal plate 5 is inclined, at this time, when the lubricating device 7 sprays lubricating oil on the surface of the steel wire rope for lubrication, the lubricating oil falling on the first rust removal plate 4 and the second rust removal plate 5 will flow to the direction of the steel wire rope, and then gather on the surface of the steel wire rope again,Thus, the lubricating oil is prevented from accumulating on the surfaces of the first rust removal plate 4 and the second rust removal plate 5, and the lubricating oil is prevented from dripping from the gap between the first rust removal plate 4 and the second rust removal plate 5, thereby further preventing the waste of lubricating oil. When the lifting block 620 rises to the highest point, the top ends of the two grabbing pieces 617 are in contact with the inclined surface inside the mounting cylinder 612 again, so that the two grabbing pieces 617 are deflected synchronously to release the lifting block 620, and at this time, the fixed plate 633 slides under the action of the first trigger block 635, the other end of the wedge-shaped block 634 is in contact with the tooth, and the bottom inclined surface is matched with the upper inclined surface of the tooth, thereby driving the fixed plate 633 and the lifting block 620 to descend in a segmented manner, and the process time is relatively long. After the lubricating work of the steel wire rope is completed in the time, the lifting block 620 descends to the lowest point inside the mounting cylinder 612, at this time, the side end inclined surface of the fixed plate 633 is extruded by the third trigger block 637, so that the fixed plate 633 is reset to the initial position, thereby driving the extrusion frame 642 to be separated from the first rust removal plate 4, so that the first rust removal plate 4 and the second rust removal plate 5 are deflected and reset to the horizontal state, so as to facilitate the next rust removal and lubricating work; After the first rust removal plate 4 and the second rust removal plate 5 are deflected downward and sealed by the deflection assembly 64 and the sealing assembly 65, the oil pump 73 is controlled to work to spray lubricating oil on the outer side of the steel wire rope in all directions through the oil injection hole 72 on the oil injection pipe 71, thereby realizing the lubricating and maintenance work of the steel wire rope.
