Description

Technical Field

[0001] The present invention relates to the technical field of elevator maintenance, and specifically provides an elevator wire rope lubrication system and a maintenance method therefor. Background Art

[0002] As a vertical passage for the operation of the elevator system in super high-rise buildings, the elevator shaft runs through the underground layer to the top space of the building, and core components such as an elevator car, a counterweight device, and guide rails are installed inside; during the operation of the elevator, the frictional vibration between the wire rope and the guide roller is one of the main noise sources; in response to this technical problem, the current solution mainly adopts a periodic maintenance strategy, that is, noise reduction is achieved by periodically lubricating the wire rope.

[0003] Existing lubrication and maintenance technologies mainly use two types of lubricants: high-viscosity lubricants and low-viscosity lubricants; high-viscosity lubricants have the advantage of a longer maintenance cycle, but there are obvious technical defects in the long-term use process: due to their high viscosity characteristics, they are prone to adsorb particulate pollutants in the environment, and these accumulated impurities will cause secondary wear on the surface of the wire rope, which instead exacerbates the mechanical damage of the wire rope; in contrast, although low-viscosity lubricants can reduce the problem of impurity accumulation, due to their strong volatility and poor persistence, they need to be replenished and maintained frequently, which not only significantly increases the workload of maintenance personnel, but also raises the operation and maintenance costs of the elevator system. Summary of the Invention

[0021] Such as Figures 1 to 10As shown in the figure, this embodiment provides an elevator wire rope lubrication system, including an elevator shaft 1. At the top of the elevator shaft 1, there is an equipment layer 2. Inside the equipment layer 2, there is an installation platform 4. A guiding roller 3 is installed on the installation platform 4. Inside the equipment layer 2, there are an oil pumping mechanism 5 and an oil treatment mechanism 6. The oil pumping mechanism 5 includes an oil storage tank 51 fixedly connected to the installation platform 4. A delivery oil pipe 54 is connected to the oil storage tank 51. The upper end of the delivery oil pipe 54 is connected to a nozzle 55. The nozzle 55 is located above the guiding roller 3. It also includes an oil pumping drive assembly 7. A pressure oil plate 52 is slidably connected inside the oil storage tank 51. The oil pumping drive assembly 7 is in transmission connection with the pressure oil plate 52 to drive the pressure oil plate 52 to slide, pumping the lubricating oil in the oil storage tank 51 to the nozzle 55 for spraying. The oil treatment mechanism 6 includes a temporary oil box 61. The temporary oil box 61 is fixedly connected to one side of the oil storage tank 51 and is located at an upper position. An oil passing hole is provided on the side of the oil storage tank 51 where the temporary oil box 61 is fixedly connected. The oil storage tank 51 is communicated with the temporary oil box 61 through the oil passing hole. A filter plate 65 is installed on the oil passing hole. A leakage hole is provided above the temporary oil box 61. The leakage hole is located below the guiding roller 3 and is used to receive the lubricating oil falling from the guiding roller 3. A scraping plate 62 is slidably connected inside the temporary oil box 61. It also includes a return oil drive assembly 8. The return oil drive assembly 8 is in transmission connection with the scraping plate 62 to drive the scraping plate 62 to slide, pushing the lubricating oil in the temporary oil box 61 back into the oil storage tank 51. Among them, a blocking block 53 is provided on the bottom surface inside the oil storage tank 51. A guiding hole 5201 adapted to the blocking block 53 is provided in the middle of the pressure oil plate 52. The pressure oil plate 52 is inclined downward from the edge to the guiding hole 5201, facilitating the smoothly flowing of the dripping lubricating oil to the lower side of the pressure oil plate 52. In the initial state of the pressure oil plate 52, its bottom surface is higher than the blocking block 53. At this time, the guiding hole 5201 is in an open state. When the guiding hole 5201 on the pressure oil plate 52 slides to engage with the blocking block 53, a relatively sealed space is formed between the inner bottom surface of the oil storage tank 51 and the pressure oil plate 52. In this state, the lubricating oil in the oil storage tank 51 can be pumped out.

[0022] The lubricating oil in the oil storage tank 51 is pressed out by the pressure oil plate 52 and sprayed onto the guiding roller 3 and the wire rope on the guiding roller 3 through the delivery oil pipe 54 and the nozzle 55. The spraying width of the nozzle 55 is the same as the width of the guiding roller 3. The nozzle 55 can be installed on the inner wall of the equipment layer 2. Using this system to replace manual regular dripping of lubricating oil between the guiding roller 3 and the wire rope reduces the maintenance frequency of maintenance personnel to a certain extent.

[0023] The oil pump drive assembly 7 includes a half gear 71 sleeved on one end of the mounting shaft 9 of the guide roller 3. A first rotating shaft is also provided in the equipment layer 2. The first rotating shaft is rotatably connected with an oil pump gear 72. A coil spring is provided between the shaft hole of the first rotating shaft and the oil pump gear 72. The outer end of the coil spring is fixedly connected to the shaft hole of the oil pump gear 72, and the inner end of the coil spring is fixedly connected to the first rotating shaft. The half gear 71 is meshed with the oil pump gear 72. A vertical rod 56 penetrating the oil storage tank 51 is provided on the top surface of the oil pressure plate 52. A horizontal plate 76 is connected to the upper end of the vertical rod 56. A vertical plate 73 is provided on the horizontal plate 76. A plurality of oil pump gear blocks 74 are provided at intervals on the vertical plates. The oil pump gear 72 is meshed with the oil pump gear blocks 74. The coil spring can quickly reset after the oil pump gear 72 loses tooth meshing with the half gear 71.

[0024] A guide plate 75 is installed on the inner wall of the equipment layer 2, and the vertical plate 73 is slidably connected to the outer side of the guide plate 75; the guide plate 75 is used to guide and limit the vertical movement of the vertical plate 73.

[0025] A strip through hole is provided at one end of the lower side wall of the temporary oil box 61 near the oil storage tank 51, and the strip through hole is used as a drop channel for impurities in the lubricating oil after treatment; a slag collecting box 67 is detachably connected to the lower side wall of the temporary oil box 61, and the slag collecting box 67 is located at the lower side of the strip through hole; a movable sealing plate 64 is slidably connected to the lower side wall of the temporary oil box 61, and the movable sealing plate 64 is used to open and close the strip through hole; it also includes a U-shaped connecting rod 6801, one end of the U-shaped connecting rod 6801 is connected to a spring rod 6802, and the other end is connected to the scraper 62, and the end of the spring rod 6802 away from the U-shaped connecting rod 6801 is connected to the movable sealing plate 64; the return oil drive assembly 8 is transmission-connected to the scraper 62 and the movable sealing plate 64 through the U-shaped connecting rod 6801. Among them, a side plate 69 is provided on the lower side wall of the temporary oil box 61, and the slag collecting box 67 is bolted and fixed to the side plate 69. In the process of pressurizing and separating the lubricating oil and impurities, the strip-shaped through hole is blocked, and the separated impurities are located on the movable sealing plate 64. In the process of dripping the lubricating oil by the nozzle 55, the strip-shaped through hole is opened, and the impurities that fell on the movable sealing plate 64 last time are scraped and dropped into the slag collecting box 67 below. In this embodiment, the top of the movable baffle 63 in the initial state is lower than the bottom surface of the upper side wall of the temporary oil box 61, that is, there is a gap between the movable baffle 63 and the upper side wall of the temporary oil box 61.

[0026] The movable sealing plate 64 and the scraper 62 are connected by a U-shaped connecting rod 6801 and a spring rod 6802, which can not only enable the movable sealing plate 64 to slide with the scraper 62, but also ensure that the movable sealing plate 64 reaches the bottom surface of the strip through hole before the scraper 62, and does not hinder the continuous sliding of the scraper 62. The oil processing mechanism 6 under the guide roller 3 can collect and pressurize the filter residue for each lubricating oil dripped on the guide roller 3, so as to achieve the effect of rapid separation of impurities and lubricating oil.

[0027] An installation groove 6101 is provided at one end of the lower side wall of the temporary oil box 61 close to the strip-shaped through hole. A limit post 66 is arranged in the installation groove 6101. A movable baffle 63 is slidably inserted on the limit post 66. A support spring is also sleeved on the limit post 66. The upper end of the support spring abuts against the lower edge of the movable baffle 63, and the lower end abuts against the lower side wall of the installation groove 6101. The movable baffle 63 can prevent the lubricating oil falling on the temporary oil box 61 from flowing out directly through the strip-shaped through hole without being recycled. The lower end of the scraper 62 is set as an inclined surface, which is inclined downward from the side close to the filter plate 65 to the side away from the filter plate 65. When the inclined surface at the lower end of the scraper 62 moves to the upper side of the movable baffle 63, it can press down the movable baffle 63, so that the movable baffle 63 contracts into the installation groove 6101.

[0028] The oil return driving assembly 8 includes a bevel gear one 81 sleeved on one end of the installation shaft 9 of the guide roller 3. A second rotating shaft is also rotatably connected in the equipment layer 2. A bevel gear two 82 is sleeved on the second rotating shaft. The bevel gear one 81 and the bevel gear two 82 are meshed. A semi-circular plate 83 is also sleeved on the second rotating shaft. A transition rod 87 is connected to the scraper 62, and a transition plate 84 is connected to the transition rod 87. The semi-circular plate 83 abuts against the outside of the transition plate 84. When the second rotating shaft drives the semi-circular plate 83 to rotate, the transition plate 84 is driven by the semi-circular plate 83 and advances forward.

[0029] A guide rod 85 is installed on the inner wall of the equipment layer 2. The guide rod 85 is slidably sleeved with the transition plate 84. A return spring 86 is also sleeved on the guide rod 85. One end of the return spring 86 is connected to the transition plate 84, and the other end is connected to the inner wall of the equipment layer 2. The return spring 86 can be used to reset the transition plate 84 for the next pressure oil filtration operation.

[0030] The lower side wall of the oil passing hole is an inclined surface, which is inclined downward from the side close to the temporary oil box 61 to the inside of the oil storage tank 51.

[0031] The present invention also discloses an elevator wire rope maintenance method, which uses an elevator wire rope lubrication system for maintenance. The specific steps are as follows: S1: The staff injects lubricating oil into the interior of the oil storage tank 51, and injects the lubricating oil below the initial position of the oil pressing plate 52.

[0032] S2: Then when the elevator is running, the guide roller 3 starts to rotate. At this time, the lubricating oil in the oil storage tank 51 is quantitatively pumped out under the action of the oil pumping mechanism 5 and the oil pumping drive assembly 7, and is sprayed onto the steel wire rope sleeved on the guide roller 3 through the nozzle 55. Specifically, when the guide roller 3 rotates, it drives the semi-gear 71 to rotate. Through the meshing of the semi-gear 71 and the oil pumping gear 72, the oil pumping gear 72 is driven to rotate in the opposite direction. At the same time, through the meshing of the oil pumping gear 72 and the oil pumping tooth block 74, the vertical plate 73 is driven to move downward. The teeth of the semi-gear 71 initially rotate upward. Then, through the cross plate 76 and the vertical rod 56, the oil pressing plate 52 is driven to move downward in the oil storage tank 51. After the guiding hole 5201 of the oil pressing plate 52 is engaged with the blocking block 53, a one-way oil outlet space is formed between the oil pressing plate 52, the blocking block 53 and the inner wall of the oil storage tank 51. At this time, the lubricating oil in the oil storage tank 51 is pressed into the oil delivery pipe 54, then reaches the nozzle 55, and finally is sprayed onto the steel wire rope sleeved on the guide roller 3 by the nozzle 55, achieving the effect of spraying oil on the steel wire rope sleeved on the guide roller 3 to reduce noise.

[0033] After the oil pressing plate 52 moves downward and pumps oil once, under the action of the coil spring, the oil pumping gear 72, the vertical plate 73 and the oil pressing plate 52 are reset to facilitate the next oil pumping operation, ensuring periodic spraying of lubricating oil during the operation of the elevator and realizing periodic maintenance of the steel wire rope.

[0034] S3: The lubricating oil dripping from the surface of the wire rope and the guide roller 3, together with the impurities adhered to the wire rope during operation, drips downward and flows into the interior of the temporary oil box 61 through the oil leakage hole in the upper part of the temporary oil box 61. At this time, the lubricating oil is collected in the temporary oil box 61 located between the scraping plate 62 and the movable baffle 63. Through the oil treatment mechanism 6 and the oil return drive assembly 8, the lubricating oil wrapped with impurities is subjected to squeezing and slag filtering treatment, so that the filtered lubricating oil re-enters the oil storage tank 51, and the impurities are collected for regular cleaning. Specifically, when the guide roller 3 rotates, it drives the first bevel gear 81 to rotate. Through the meshing of the first bevel gear 81 and the second bevel gear 82, it drives the semi-circular plate 83 to rotate, so as to use the semi-circular plate 83 to push against the transition plate 84 to move. Under the action of the transition rod 87, the scraping plate 62 is pushed to slide horizontally in the temporary oil box 61, so that the lubricating oil wrapped with impurities falling in the temporary oil box 61 is pushed. At the same time, through the U-shaped connecting rod 6801 and the spring rod 6802, the movable sealing plate 64 connected to the scraping plate 62 slides on the bottom surface of the temporary oil box 61 following the scraping plate 62. When the movable sealing plate 64 abuts against the outer wall of the oil storage tank 51, the strip-shaped through hole is blocked. At this time, the lubricating oil is still between the movable baffle 63 and the scraping plate 62. When the scraping plate 62 slides a certain distance, part of the lubricating oil wrapped with impurities flows from the upper side of the movable baffle 63 to between the movable baffle 63 and the filter plate 65. As the scraping plate 62 continues to slide, the pressure on the lubricating oil continues to increase, and then the lubricating oil rushes out from the filter plate 65 and enters the oil storage tank 51. The scraping plate 62 continues to slide, pushing against the movable baffle 63 to make the movable baffle 63 slide down and retract into the installation groove 6101. At this time, under the filtering action of the filter plate 65, most of the lubricating oil is recovered into the oil storage tank 51, and the impurities and a small amount of lubricating oil are all located between the scraping plate 62, the filter plate 65, the movable sealing plate 64 and the upper side wall of the temporary oil box 61. At this time, the separation operation of the impurities and the lubricating oil is completed to realize the reuse of the lubricating oil.

[0035] Among them, the initial state of the oil pressing plate 52 is that the oil pressing plate 52 is located above the blocking block 53, and the guide hole 5201 is in an open state. At the same time, under the control of the oil pumping drive mechanism, the first part of the oil pressing plate 52 during the downward movement does not achieve the oil pumping effect. At this time, the lubricating oil recovered into the oil storage tank 51 through the filter plate 65 last time falls on the oil pressing plate 52. The upper end surface of the oil pressing plate 52 slopes downward from the edge to the guide hole 5201, so as to facilitate the smooth flow of the lubricating oil to the lower place and flow through the guide hole 5201 to the lower part of the oil pressing plate 52.

[0036] After a separation operation of impurities and lubricating oil is completed, the return spring 86 pulls the transition plate 84, the transition rod 87 and the scraper 62 back to their original positions. The movable sealing plate 64 follows the scraper 62 back to its original position under the action of the U-shaped connecting rod 6801 and the spring rod 6802. After the movable sealing plate 64 is removed, the impurities and trace amounts of lubricating oil between the upper side walls of the scraper 62, the filter plate 65, the movable sealing plate 64 and the temporary oil box 61 fall into the slag collection box 67 through the strip-shaped through holes. The movable baffle 63 returns to its original position under the action of the support spring, so that the separation operation of the dripping impurities and lubricating oil can be carried out after each oil pumping.

[0037] S4: The capacity of the oil storage tank 51 is limited, and the lubricating oil will gradually decrease with use. It is necessary for maintenance personnel to regularly add lubricating oil to the inside of the oil storage tank 51, regularly clean the impurities in the temporary oil box 61, and replace or clean the filter plate 65.

[0038] The cooperation of the lubricating oil with a low viscosity and the oil pumping mechanism 5 and the oil treatment mechanism 6 can recycle and pressurize the filtered lubricating oil containing some impurities, quickly separate the impurities from the lubricating oil, realize the reuse of the lubricating oil, reduce the frequency of lubricating oil addition by maintenance personnel, and reduce the workload of maintenance personnel to a certain extent.

[0039] The above are only the preferred embodiments of the present invention that can be implemented, and do not limit the scope of the rights of the present invention. Any equivalent changes made by using the content of the specification and drawings of the present invention are included in the scope of the rights of the present invention.
