Description

Technical Field

[0001] This invention relates to the field of elevator wire rope maintenance technology, and more specifically, to a maintenance device for elevator wire ropes. Background Technology

[0002] Elevator wire ropes are a crucial component of elevator operation, affecting not only safety but also the elevator's lifespan. Proper maintenance can extend the lifespan of the wire ropes and ensure safe and reliable elevator operation.

[0003] According to patent publication number CN117303162A, published on 2023-12-29, an elevator wire rope self-maintenance device belongs to the field of elevator maintenance technology. It includes a storage box with a detachable top plate on its upper surface. The top of the storage box is filled with lubricating oil. A pressure-boosting piston for squeezing the lubricating oil is slidably connected to the bottom of the storage box. A battery is also installed at the bottom of the storage box, with a controller on top. Height adjustment components for adjusting the pressure-boosting piston are located on both sides of the battery. A maintenance mechanism is located on one side of the storage box, and a support mechanism for supporting and adjusting the height of the maintenance mechanism is located on the side of the storage box. The support mechanism includes a second limiting plate. Through the cooperation of multiple structures, the maintenance device achieves sufficient lubrication of the elevator wire rope, and the device is applicable to different models of elevator wire ropes, thus broadening its applicability. However, if lubricating oil is applied directly to the elevator wire rope without first removing dust from it, the following problems may occur: 1. Accelerated wear: Dust particles trapped between the wire rope and pulleys or guide rails increase friction and accelerate internal and external wear of the wire rope. 2. Reduced lubrication effect: Dust mixed with lubricating oil leads to uneven lubrication, affecting system performance. 3. Increased corrosion risk: Chemical components in dust may react with lubricating oil, promoting corrosion of metal parts. 4. Safety hazards: Increased risk of wire rope breakage, endangering the safe operation of the elevator. 5. Increased maintenance costs: Incorrect maintenance shortens the life of the wire rope, increases replacement frequency and operating costs. If manual removal of dust from the elevator wire rope is required before using this device, its efficiency in maintaining the elevator wire rope is low.

[0004] Therefore, it is necessary to design an efficient maintenance device for elevator wire ropes. Summary of the Invention

The first rotating shaft of the movable cleaning section is rotatably connected to the connecting plate. When the cylinder drives the connecting plate to move down, the distance between the movable cleaning section and the fixed cleaning section decreases. When the connecting plate moves down to the bottom, the gears on the two first rotating shafts mesh.

[0008] Optionally, the oil spraying mechanism includes an oil storage tank, a spray gun, and an oil supply pipe. The oil storage tank is installed on the second frame, and the spray gun is inserted through the second frame. An oil supply pipe connects the spray gun and the oil storage tank.

[0009] Optionally, it also includes a coating mechanism. The coating mechanism is provided inside the second frame. The coating mechanism includes mounting blocks and sponge rollers. Mounting blocks are symmetrically mounted inside the second frame. Sponge rollers are symmetrically rotatably connected inside the second frame. The sponge rollers are respectively attached to the adjacent mounting blocks.

[0010] Optionally, the side of the mounting block that contacts the sponge roller is semi-circular.

[0011] Optionally, it also includes a collection mechanism. The second frame is provided with a collection mechanism, which includes a fixed rod, a collection frame and an elastic element. The fixed rod is connected to the second frame, and the collection frame is slidably connected to the fixed rod. An elastic element connects the collection frame and the second frame.

[0012] Optionally, the collection frame has a bevel and a groove on the side near the sponge roller.

[0013] Optionally, the collection mechanism further includes a collection tube, the inner bottom surface of the collection frame is inclined, and the collection tube passes through the lower side of the inner bottom surface of the collection frame.

[0014] Optionally, it also includes a pushing mechanism. The first frame is provided with a pushing mechanism, which includes a connecting rod and a second guide rod. The connecting rod is slidably connected to the first frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention completes the work of spraying lubricating oil onto elevator wire ropes by installing a cleaning mechanism and then spraying the lubricating oil onto the elevator wire ropes with a spray gun. This makes the device not only capable of spraying lubricating oil onto elevator wire ropes, but also capable of cleaning elevator wire ropes without the need for manual cleaning, saving a lot of time and greatly improving the efficiency of the device in maintaining elevator wire ropes, while also ensuring effective maintenance of elevator wire ropes.

[0018] 2. By installing a coating mechanism, if the lubricating oil sprayed on the part of the elevator wire rope in contact with the sponge roller is insufficient, the sponge roller will recoat that part of the elevator wire rope; conversely, if the lubricating oil sprayed on that part of the elevator wire rope is excessive, the sponge roller will absorb the excess lubricating oil, thereby making the lubricating oil on the elevator wire rope more evenly coated, and further ensuring effective maintenance of the elevator wire rope.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: A maintenance device for elevator wire ropes, such as... Figures 1-4As shown, the system includes a base 1, a first frame 101, a guide wheel 1011, a second frame 102, a first guide rod 1021, a cleaning mechanism 2, a connecting plate 221, a winding mechanism 3, and an oil spraying mechanism 4. The first frame 101 is connected to the base 1, and the guide wheel 1011 for guiding the elevator wire rope is connected inside the first frame 101. The second frame 102 is connected to the right side of the base 1, and the first guide rod 1021 is connected to the upper part of the second frame 102. The cleaning mechanism 2 is provided on the base 1. The cleaning mechanism 2 includes a first motor 21, a cleaning assembly, and a cylinder 25. The first motor 21 is bolted to the base 1. The cleaning assembly consists of a fixed cleaning part fixedly disposed on the lower side and a movable cleaning part slidably disposed on the upper side. Both the fixed cleaning part and the movable cleaning part are provided with a first rotating shaft 22 and a steel brush roller 23 mounted on the first rotating shaft. The first rotating shaft 22 of the fixed cleaning part is coaxially connected to the first motor 21. The cleaning assembly also includes a gear 24 and a cylinder. 25. A gear 24 is connected to the first rotating shaft 22. A cylinder 25 is installed on the base 1 by bolts. A connecting plate 221 is connected to the telescopic end of the cylinder 25. The first rotating shaft 22 of the movable cleaning part is rotatably connected to the connecting plate 221. When the cylinder 25 drives the connecting plate 221 to move down, the distance between the movable cleaning part and the fixed cleaning part decreases. When the connecting plate 221 moves down to the bottom, the gears 24 on the two first rotating shafts 22 mesh. A winding mechanism 3 and an oil spraying mechanism 4 are provided on the second frame 102. The telescopic end of the cylinder 25 will take the upper cleaning component down until the gear 24 of the upper cleaning component meshes with the gear 24 of the lower cleaning component. After the cylinder 25 is closed, the first motor 21 is started. The output shaft of the first motor 21 will drive the first rotating shaft 22 to rotate, thereby driving the steel brush roller 23 and the gear 24 to rotate together. Due to the meshing of the upper and lower gears 24, the upper and lower cleaning components will rotate and run together.

[0033] like Figures 2-5 As shown, the winding mechanism 3 includes a second motor 31, a second rotating shaft 32, and a baffle 33. The second motor 31 is mounted on the second frame 102. The output shaft of the second motor 31 is connected to the second rotating shaft 32. The baffle 33 is detachably connected to the end of the second rotating shaft 32 away from the second motor 31 by means of threaded engagement. The output shaft of the second motor 31 will drive the second rotating shaft 32 to rotate, thereby winding up the elevator wire rope and pulling the elevator wire rope to the right.

[0034] like Figures 4-6As shown, the oil spraying mechanism 4 includes an oil storage tank 41, a spray gun 42, and an oil supply pipe 43. The oil storage tank 41 for storing lubricating oil is installed on the second frame 102, and the spray gun 42 is installed on the second frame 102. The oil supply pipe 43 connects the spray gun 42 and the oil storage tank 41. When the elevator wire rope moves to the left side of the spray gun 42, the water pump inside the spray gun 42 is started. The water pump will draw the lubricating oil in the oil storage tank 41 into the spray gun 42 through the oil supply pipe 43, and then spray it onto the elevator wire rope through the spray gun 42 to complete the work of spraying lubricating oil onto the elevator wire rope.

[0035] When this device is needed, the preparation steps are as follows: First, place the elevator wire rope coil that needs maintenance on the material placement wheel outside the device, so that the end of the elevator wire rope is close to the upper edge of the left guide wheel 1011, then pass between the two cleaning components, contact the upper edge of the right guide wheel 1011, then move it up through the two sponge rollers 52, and finally contact the upper edge of the first guide rod 1021 before winding it around the second rotating shaft 32. The part of the elevator wire rope that passes through the inside of this device has been maintained in advance; add lubricating oil into the oil tank, and then pour an appropriate amount of lubricating oil evenly onto the two sponge rollers 52.

[0036] After completing the above preparation steps, start cylinder 25. The telescopic end of cylinder 25 will drive the connecting plate 221 to move downward. When the connecting plate 221 moves downward, the upper cleaning component will also move downward until the gear 24 of the upper cleaning component meshes with the gear 24 of the lower cleaning component. After closing cylinder 25, start the first motor 21. The output shaft of the first motor 21 will drive the first rotating shaft 22 to rotate, thereby driving the steel brush roller 23 and the gear 24 to rotate together. Due to the meshing of the upper and lower gears 24, the upper and lower cleaning components will rotate together. At this time, the elevator wire rope is located in the middle of the two steel brush rollers 23. The rotating steel brush rollers 23 will remove the dust on the elevator wire rope. At the same time as driving the first motor 21, start the second motor 31. The output shaft of the second motor 31 will... This will drive the second rotating shaft 32 to rotate, thereby winding up the elevator wire rope and pulling it to the right. This allows the device to continuously clean the elevator wire rope without manual cleaning. When the elevator wire rope moves to the left side of the spray gun 42, the water pump inside the spray gun 42 is activated. The water pump will draw lubricating oil from the oil storage tank 41 into the spray gun 42 through the oil pipe 43, and then spray it onto the elevator wire rope through the spray gun 42, completing the work of spraying lubricating oil onto the elevator wire rope. This means that the device not only has the function of spraying lubricating oil onto the elevator wire rope, but also can clean the elevator wire rope without manual cleaning, saving a lot of time and greatly improving the efficiency of the device in maintaining the elevator wire rope, while also ensuring effective maintenance of the elevator wire rope.

[0037] Example 2: Based on Example 1, such as Figures 6-8 As shown, it also includes a coating mechanism 5. The coating mechanism 5 is provided inside the second frame 102. The coating mechanism 5 includes a mounting block 51 and a sponge roller 52. The mounting blocks 51 are symmetrically installed on the left and right sides inside the second frame 102. The sponge rollers 52 are symmetrically rotatably connected on the left and right sides inside the second frame 102. The sponge rollers 52 are respectively attached to the adjacent mounting blocks 51. The side of the mounting block 51 that is attached to the sponge roller 52 is semi-arc. The sponge roller 52 will rotate outward due to the upward movement of the elevator wire rope. At this time, the sponge roller 52 will be squeezed due to the influence of the protruding mounting block 51, and the excess lubricating oil in the sponge roller 52 will be squeezed out.

[0038] like Figures 4-6 , Figure 8 and Figure 9 As shown, it also includes a collection mechanism 6. The second frame 102 is provided with a collection mechanism 6. The collection mechanism 6 includes a fixing rod 61, a collection frame 62, an elastic element 63, and a collection tube 621. The fixing rod 61 is connected to the second frame 102. The collection frame 62 is slidably connected to the fixing rod 61. The side of the collection frame 62 near the sponge roller 52 is provided with an inclined surface and a groove 622. The elastic element 63 is connected to the second frame 102 through a spring seat. The collection mechanism 6 also includes a collection tube 621 passing through the lower side of the inner bottom surface of the collection frame 62, which is an inclined surface.

[0039] like Figure 10 As shown, it also includes a pushing mechanism 7. The first frame 101 is provided with a pushing mechanism 7, which includes a connecting rod 71 and a second guide rod 72. The connecting rod 71 is slidably connected to the first frame 101. The right end of the connecting rod 71 is connected to the collecting frame 62, and the left end of the connecting rod 71 is connected to the second guide rod 72. The middle part of the second guide rod 72 is an inclined surface. The connecting plate 221 moves down along the inclined surface on the second guide rod 72, and the second guide rod 72 will drive the connecting rod 71 to move to the left on the first frame 101. At this time, the collecting frame 62 will also move to the left. The elevator wire rope located in the second frame 102 will move to the left along the inclined surface on the left side of the collecting frame 62 and enter the groove 622 on the collecting frame 62, so that the collecting frame 62 can limit the elevator wire rope, which is convenient for the subsequent winding of the elevator wire rope.

[0040] like Figure 11As shown, it also includes a moving mechanism 8. The moving mechanism 8 is provided on the second frame 102. The moving mechanism 8 includes a pulley 81, a reciprocating screw 82, a third guide rod 83, and a push plate 84. The reciprocating screw 82 is rotatably connected to the second frame 102. The pulley 81 is connected between the second rotating shaft and the reciprocating screw 82. The third guide rod 83 is connected to the second frame 102. The push plate 84 is slidably connected to the third guide rod 83. The push plate 84 is threadedly connected to the reciprocating screw 82. When the second rotating shaft 32 rotates, the pulley 81 will drive the reciprocating screw 82 to rotate together. When the reciprocating screw 82 rotates, the push plate 84 will move along the third guide rod 83 towards the baffle 33. During this process, the push plate 84 will push the elevator wire rope to move together, thereby changing the winding position of the elevator wire rope, so that the device can evenly wind up the elevator wire rope.

[0041] After the elevator wire rope has been coated with lubricating oil, uneven application may occur due to variations in wire rope diameter. Because the sponge roller 52 is made of soft material, it can completely wrap around and closely contact the outer wall of the elevator wire rope. When the elevator wire rope passes between the two sponge rollers 52, if the portion of the wire rope in contact with the sponge roller 52 has insufficient lubricating oil, the sponge roller 52 will apply additional lubricating oil to that portion. Conversely, if too much lubricating oil is applied to that portion of the wire rope, the sponge roller 52 will absorb the excess oil, thus ensuring a more even application of lubricating oil to the elevator wire rope. This ensures effective maintenance of the elevator wire rope. As the cylinder 25 moves the connecting plate 221 downward, the connecting plate 221 moves downward along the inclined surface on the second guide rod 72. During this process, the second guide rod 72 moves the connecting rod 71 to the left on the first frame 101. At this time, the collecting frame 62 also moves to the left, and the elastic element 63 is compressed. During this process, the elevator wire rope located in the second frame 102 moves to the left along the inclined surface on the left side of the collecting frame 62 and enters the groove 622 on the collecting frame 62. This allows the collecting frame 62 to limit the elevator wire rope, facilitating the subsequent winding of the elevator wire rope.

[0042] The sponge roller 52 will rotate outward due to the upward movement of the elevator wire rope. Since the side of the mounting block 51 that contacts the sponge roller 52 is semi-circular, when the sponge roller 52 rotates, the part that was not previously in contact with the mounting block 51 will come into contact with the mounting block 51. At this time, affected by the protruding mounting block 51, the sponge roller 52 will be squeezed, and the excess lubricating oil in the sponge roller 52 will be squeezed out and drip into the collection frame 62 below. Since the inner bottom surface of the collection frame 62 is inclined, the lubricating oil will flow to the right and enter the external collection container through the collection pipe 621. The collected lubricating oil can be reused, thereby effectively saving lubricating oil and reducing maintenance costs.

[0043] Since the position of the second rotating shaft 32 is fixed, the position for winding the elevator wire rope is also fixed. Therefore, the elevator wire rope cannot be wound evenly onto the second rotating shaft 32. When the second rotating shaft 32 rotates, the pulley 81 drives the reciprocating screw 82 to rotate together. When the reciprocating screw 82 rotates, the push plate 84 moves along the third guide rod 83 towards the baffle 33. During this process, the push plate 84 pushes the elevator wire rope to move together, thereby changing the winding position of the elevator wire rope. This allows the device to wind the elevator wire rope evenly, facilitating the subsequent use of the elevator wire rope coil. After the winding work is completed, rotate the baffle 33 to remove it from the second rotating shaft 32. At this time, the maintained elevator wire rope coil can be removed. After removing the elevator wire rope coil, reset the baffle 33. After the maintenance work is completed, start the cylinder 25 to reset the upper cleaning mechanism 2 and the collecting mechanism 6, and then shut down and clean the device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
