DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1 - Figure 6The utility model discloses an elevator running cable protection device, including a base 1, a support plate 2 is fixedly connected to one side of the base 1, arc-shaped buffer surfaces 3 are arranged at the upper and lower edges of the support plate 2, and limiting plates 4 are arranged at the left and right edges of the support plate 2. A cavity 5 is opened in the base 1 and a liquid storage tank 6 is fixedly connected to the base 1. The top of the liquid storage tank 6 is connected to an infiltration component 7, and a coating component 8 is connected to the side of the support plate 2 away from the base 1.

[0027] In this embodiment, the elevator accompanying cable is usually made into a flat shape in order to reduce damage caused when winding. The flat cable will increase the lateral wind resistance, causing the accompanying cable to shake when the elevator runs at high speed, causing the cable to rub against the car and be damaged.

[0028] Therefore, a base 1 is provided on the outside of the car, and a support plate 2 is connected to one side of the base 1, which contacts the cable through the support plate 2 to prevent the cable from contacting the car; then, arc-shaped buffer surfaces 3 are processed on the top and bottom of the support plate 2, so that the cable will not contact and rub against the edge corners of the support plate 2 when it shakes, which can further improve the protection performance of the cable; then, limiting plates 4 are connected to the left and right edges of the support plate 2, which can limit the shaking area of ​​the cable when it shakes, prevent it from slipping out of the supporting area of ​​the support plate 2, and make the support plate 2 better protect the cable.

[0029] observe Figure 2 and Figure 4 It can be found that a liquid storage tank 6 is provided in the base 1, and an infiltration component 7 is connected to the top of the liquid storage tank 6, and the protective liquid stored in the liquid storage tank 6 can be guided to the surface of the support plate 2 through the infiltration component 7, so that the cable passing through the surface of the support plate 2 will adhere to a layer of protective liquid, which can further reduce the friction caused by the cable contacting the surface of the support plate 2 when shaking, thereby further improving the protection effect of the cable. Anti-aging agents can also be added to the protective liquid to provide maintenance for the cable while reducing the friction between the cable and the support plate 2, which can reduce the aging of the cable and further improve the practicality of the protective device.

[0030] Since the cable is in single-sided contact with the support plate 2, the side of the cable away from the support plate 2 cannot be coated with the protective liquid, so that the protection liquid coverage rate of the cable outer wall is not high, affecting the actual maintenance effect of the protective liquid. Figure 3 It can be found that a coating component 8 is connected to the side of the support plate 2 away from the base 1. The coating component 8 is used to evenly scrape the protective liquid adhered to the surface of the cable, and accumulate excess protective liquid, so that the excess protective liquid flows to the side of the cable where no protective liquid adheres, so that the entire cable is evenly coated with the protective liquid, thereby effectively increasing the coverage of the protective liquid.

[0031] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the infiltration assembly 7 includes an infiltration rope 71, a fixed block 72 and a limiting unit 73. The fixed block 72 is slidably arranged on the top of the liquid storage tank 6 and is connected to the liquid storage tank 6 through the limiting unit 73. A pressure groove 9 is provided on the side of the fixed block 72 close to the support plate 2. A infiltration seam 10 is provided on the support plate 2 at a location of the pressure groove 9. The infiltration rope 71 is clamped between the infiltration seam 10 and the pressure groove 9. Both ends of the infiltration rope 71 pass through the liquid storage tank 6 and extend into the liquid storage tank 6.

[0032] In this embodiment, since the liquid storage tank 6 stores protective liquid, and the protective liquid will gather at the bottom of the liquid storage tank 6 under the action of gravity, an infiltration rope 71 is provided to utilize the capillary phenomenon of the liquid between the fibers of the infiltration rope 71 to extract the protective liquid in the liquid storage tank 6, so as to achieve the effect of transporting the protective liquid to the infiltration seam 10.

[0033] However, since the cable shakes when the car moves, the impregnation rope 71 will be impacted and shifted, causing the impregnation rope 71 to slip out of the impregnation seam 10, affecting the transportation of the protective liquid, a fixing block 72 is provided, and a pressing groove 9 for clamping the impregnation rope 71 is opened on the side of the fixing block 72 close to the support plate 2. The fixing block 72 is used to fix the impregnation rope 71 to prevent the impregnation rope 71 from slipping out of the impregnation seam 10 and affecting the lubrication of the cable.

[0034] At the same time, a limiting unit 73 for limiting the fixed block 72 is also provided on the top of the liquid storage tank 6, which can prevent the fixed block 72 from deflecting under the impact caused by the shaking of the cable, so that the fixing effect of the fixed block 72 on the infiltration rope 71 is more stable.

[0035] In a further preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, the limiting unit 73 includes a limiting block 731, a ball 732 and a spring 733. The bottom of the limiting block 731 is fixedly connected to the liquid storage tank 6. The outer wall of the limiting block 731 is provided with a circular groove and a ball 732. The ball 732 is connected to the circular groove through a spring 733. The bottom of the fixed block 72 is provided with a slot 11 for inserting the limiting block 731, and the inner wall of the slot 11 is provided with a slot 12 that fits the ball 732.

[0036] In this embodiment, since the impregnation rope 71 needs to be soaked before use so that the impregnation rope 71 is filled with protective liquid to save the long waiting time for capillary phenomenon, it is necessary to unlock the fixed block 72 when the impregnation rope 71 is soaked, and then use the fixed block 72 to lock the impregnation rope 71 after the impregnation rope 71 is soaked. Therefore, the fixed block 72 needs to flexibly change the connection state with the liquid storage tank 6.

[0037] So observe Figure 5 and Figure 6 It can be found that a limiting block 731 is fixedly connected to the top of the liquid storage tank 6, and a circular groove is opened in the limiting block 731, and a ball 732 is connected in the circular groove through a spring 733, and then a slot 11 is opened at the bottom of the fixed block 72, and a card slot 12 that fits with the ball 732 is set in the slot 11, so that the fixed block 72 can change the connection state of the fixed block 72 and the liquid storage tank 6 by squeezing the ball 732 through the inner wall of the slot 11 to change the fitting state of the ball 732 and the card slot 12, which can make the installation of the infiltration rope 71 more convenient and further reduce the difficulty of using the infiltration component 7.

[0038] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, the coating assembly 8 includes a limiting plate 81 and a scraper plate 82. Both sides of the limiting plate 81 are bent to form a connecting portion 13 connected to the limiting plate 4. The scraper plates 82 are arranged at the bottom of the inner side walls of the limiting plate 81, the connecting portion 13, the limiting plate 4 and the support plate 2. A plurality of scraper plates 82 are connected end to end in sequence and are ring-shaped and sleeved on the outside of the cable.

[0039] In this embodiment, since the cable is only in contact with the support plate 2 on one side, the protective liquid can only be applied to one side of the cable in the case of natural application, so that the other side of the cable cannot be coated with the protective liquid, thereby affecting the protective effect of the protective liquid on the cable.

[0040] So observe Figure 1 It can be found that a limiting plate 81 is provided on the side of the support plate 2 away from the base 1, and the two sides of the limiting plate 81 are bent to form a connecting portion 13 connected to the limiting plate 4, and then a scraping plate 82 is provided on the inner side wall of the limiting plate 81, the connecting portion 13, the limiting plate 4 and the support plate 2, and multiple scraping plates 82 are connected end to end in sequence, such as Figure 3As shown, the annular sleeve is arranged on the outside of the cable, so that when the cable passes through the scraper plate 82, the protective liquid adhering to the surface will be evenly spread by the scraper plate 82, and the excess protective liquid will be intercepted. The accumulated protective liquid will gradually accumulate, so that the local protective liquid is excessive and spreads toward the edge, so that the excess protective liquid flows along the edge where the scraper plate 82 contacts the cable to the other side of the cable, and is smeared on the surface of the cable when the cable moves, which can effectively increase the coverage rate of the protective liquid on the cable, improve the practicability of the protective liquid, and further improve the protective effect of the protective liquid on the cable.

[0041] In a further preferred embodiment of the present invention, Figure 4 As shown, the limit plate 81 is located below the wetting seam 10, and the limit plate 81, the connecting portion 13, the limiting plate 4 and the supporting plate 2 form an elliptical ring, and a gap for forming a liquid storage tank is reserved between the inner wall of the ring and the outer wall of the cable.

[0042] In this embodiment, since the scraper plate 82 needs to evenly scrape the protective liquid on the outer wall of the cable and store the excess protective liquid for brushing the protective liquid on the side of the cable to which the protective liquid cannot directly adhere, the limiting plate 81, the connecting part 13, the limiting plate 4 and the supporting plate 2 are assembled into a ring, and a gap is left between the inner wall of the ring and the outer wall of the cable, so that the excess protective liquid scraped off by the scraper plate 82 can be stored in the gap and spread along the gap to the side of the cable without protective liquid, which can effectively improve the coverage rate of the protective liquid, thereby improving the protective effect of the protective liquid on the cable.

[0043] In a further preferred embodiment of the present invention, Figure 4 As shown, the scraper plate 82 is made of rubber made of a highly elastic polymer material, and a plurality of scraper plates 82 are assembled to form an annular scraper plate 82 which gradually inclines inward from top to bottom to present a closed shape.

[0044] In this embodiment, by making the scraper plate 82 out of rubber of a highly elastic polymer material, the scraper plate 82 can have good elasticity, so that the scraper plate 82 can be deformed when the cable is shaken and squeezed, so as to keep the edge of the scraper plate 82 in contact with the cable, so that the scraper plate 82 can stably and evenly scrape the protective liquid on the surface of the cable.

[0045] By making the annular scraper plate 82 composed of multiple scraper plates 82 gradually tilt inward from top to bottom to form a closed shape, the scraper plate 82 can be stretched open when the cable passes through the scraper plate 82, so that the bottom edge of the scraper plate 82 remains in contact with the outer wall of the cable, thereby avoiding excess protective liquid from leaking along the contact edge of the scraper plate 82 and the cable.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
