DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-Figure 8A rail crane safety operation device shown in the figure comprises a rail crane 1, which is used to transport articles. A plurality of hanging baskets 2 are installed on the upper side of the rail crane 1. The function of the hanging baskets 2 is to place and reel in steel cables 23. A box 3 is installed between two adjacent hanging baskets 2. The box 3 is used to fix and place articles inside the box. Two rotating shafts 4 are rotatably connected inside the box 3. Rollers 5 are fixedly connected to the outer sides of the rotating shafts 4. Steel cables 23 are slidably connected between the two rollers 5. The steel cables 23 are slidably connected by pulling or loosening the steel cables 23, thereby further driving the two rollers 5 to rotate and driving the rotating shaft 4 to rotate. A driving mechanism is provided inside the box body 3, and the mechanical mechanism inside the box body 3 is driven by the driving mechanism. A conveying mechanism is installed on the inner wall of the box body 3. Brushing mechanisms are provided on both sides of the inner wall of the box body 3. The lubricating oil is conveyed to the brushing mechanism by the conveying mechanism and the brushing mechanism, and the inside of the steel cable 23 is brushed by the brushing mechanism. A detection mechanism is provided on the bottom wall of the box body 3, and the inside of the steel cable 23 is detected by the detection mechanism to detect problems in time. Two scrapers 24 are fixedly connected to the bottom of the box body 3. The function of the scraper 24 is to remove stains on the surface of the steel cable 23.

[0019] The driving mechanism includes multiple mounting plates 6 and fan gears 15. The mounting plates 6 are fixedly connected to the inner wall of the box body 3. The fan gear 15 is fixedly connected to the outer side of the rotating shaft 4 by fixing the mounting plates 6. A sliding rod 7 is fixedly connected between two adjacent mounting plates 6. The sliding rod 7 is further fixed to ensure that the sliding rod 7 is fixed. A slider 8 is slidably connected to the outer side of the sliding rod 7. A rack plate 9 is fixedly connected to the side of the slider 8 away from the sliding rod 7. The slider 8 slides to further drive the rack plate 9 to slide. The rack plate 9 and the fan gear 15 are meshed. By meshing the rack plate 9 and the fan gear 15, when the fan gear 15 rotates, the rack plate 9 can be further driven to slide.

[0020] The conveying mechanism includes a liquid storage tank 12, which is fixedly connected to the inner wall of the box body 3. The function of the liquid storage tank 12 is to store the lubricating oil. A push plate 11 is slidably connected to the inside of the liquid storage tank 12, and a one-way valve 13 is fixedly connected to the outside of the liquid storage tank 12. The push plate 11 inside the liquid storage tank 12 slides to reduce the air pressure inside the liquid storage tank 12. When the air pressure inside the liquid storage tank 12 is reduced, the lubricating oil inside the liquid storage tank 12 is discharged under the action of the one-way valve 13. A double-headed joint 14 is fixedly connected to the side of the one-way valve 13 away from the push plate 11. The function of the double-headed joint 14 is to divert the discharged lubricating oil. A push rod is fixedly connected to one side of the push plate 11 10, one end of the push rod 10 away from the push plate 11 passes through the liquid storage tank 12 and is fixedly connected to the outside of the rack plate 9. By connecting the push rod 10 to one side of the push plate 11 and fixing the push rod 10 and the rack plate 9, when the rack plate 9 slides, the push rod 10 is further driven to slide, so that the push plate 11 slides. A third pressure spring 32 is sleeved on the outside of the push rod 10. By setting the third pressure spring 32, when the rack plate 9 slides and drives the push rod 10 to slide, the third pressure spring 32 will be squeezed. When the rack plate 9 is reset, it can be reset by the third pressure spring 32, further pushing the rack plate 9 to quickly reset.

[0021] The brushing mechanism includes a fixed column 16, one side of which is fixedly connected to the inner wall of the box body 3. The function of the fixed column 16 is to support the entire brushing mechanism and to limit the connecting rod 17. The fixed column 16 is slidably connected to the connecting rod 17, one side of the connecting rod 17 is fixedly connected to a brush plate 18, and the other side of the connecting rod 17 is fixedly connected to a limiting plate 19. By respectively installing the brush plate 18 and the limiting plate 19 at both ends of the connecting rod 17, when the brush plate 18 or one of the brush plates 18 slides, it will drive the other to slide. The side of the limiting plate 19 away from the connecting rod 17 is fixedly connected to a first pressure spring 20. The function of the first pressure spring 20 is to provide a thrust to push the limiting plate 19 to slide. A water-absorbing sponge 21 is fixedly connected to the brush plate 18, and a brush 22 is fixedly connected to the side of the brush plate 18 away from the connecting rod 17. By arranging the water-absorbing sponge 21 and the brush 22, the lubricating oil can be temporarily stored, and the lubricating oil can be applied to the outside of the steel cable 23 by the action of the brush 22.

[0022] One end of the first pressure spring 20 away from the limit plate 19 is fixedly connected to the inner wall of the fixed column 16. By fixing the first pressure spring 20, it is ensured that the first pressure spring 20 can effectively push the limit plate 19 to slide during the process of pressure contraction and resetting. Two protrusions are installed on the outer side of the limit plate 19, and the protrusions are slidably connected to the inner wall of the fixed column 16. The protrusions are installed on the outer side of the limit plate 19 to prevent the limit plate 19 from rotating during the sliding process, which leads to the effect that the surface of the steel cable 23 cannot be coated. A hose is installed between the double-headed joint 14 and the water-absorbing sponge 21. By installing a hose between the double-headed joint 14 and the water-absorbing sponge 21, the lubricating oil can be discharged into the hose through the double-headed joint 14, and then discharged into the water-absorbing sponge 21 through the hose.

[0023] The detection mechanism includes a mounting column 25, the bottom of which is fixedly connected to the bottom wall of the box body 3, and a plurality of connecting rods 26 are slidably connected inside the mounting column 25. The function of the connecting rod 26 is to connect the measuring block 27 and the connecting plate 29 to ensure that one of them slides and can drive the other to slide. A measuring block 27 is fixedly connected to one side of the connecting rod 26. The function of the measuring block 27 is to detect the surface of the steel cable 23 by contacting the surface of the steel cable 23. A connecting plate 29 is fixedly connected to the other side of the connecting rod 26. The function of the connecting plate 29 is to slide and contact with the paddle 31 to transmit the signal of the damaged steel cable 23 to the paddle 31, so as to ensure that the problem of the steel cable 23 is discovered in time. A second pressure spring 28 is sleeved on the outer side of the connecting rod 26. By setting the second pressure spring 28, the measuring block 27 is pushed to slide, so that the measuring block 27 is always in contact with the steel cable 23 to detect the steel cable 23.

[0024] Two alarms 30 are fixedly connected to the outside of the box 3. Two opposite sides of the two alarms 30 are electrically connected to two paddles 31. The paddles 31 provide the alarms 30 with a signal that the steel cable 23 is damaged, and the alarms 30 perform alarm processing.

[0025] The outer side of the measuring block 27 is slidably connected to the inner wall of the mounting column 25. By sliding the measuring block 27 inside the mounting column 25, the accuracy of the measuring block 27 in detecting the steel cable 23 is further ensured. One end of the second pressure spring 28 is fixedly connected to the side of the measuring block 27 close to the connecting rod 26, and the other end of the second pressure spring 28 is fixedly connected to the inner wall of the mounting column 25. By fixing the two ends of the second pressure spring 28 at different places respectively, it is ensured that the elastic force provided by the second pressure spring 28 can push the measuring block 27 to slide.

[0026] Working principle: When the rail crane is in operation, the steel cable 23 is wound or lowered by starting the hanging basket 2. When the steel cable 23 is wound or lowered, the steel cable 23 will drive the two rollers 5 on its outer side to slide through its own sliding, and the sliding of the rollers 5 drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it further drives the fan gear 15 to rotate, and the fan gear 15 and the rack plate 9 are meshed. When the fan gear 15 rotates, it drives the rack plate 9 to slide, and the rack plate 9 slides, thereby pushing the push rod 10 to slide, and further drives the push plate 11 to slide. When the push plate 11 slides, the lubricating oil inside the liquid storage tank 12 will be discharged. At this time, the discharged lubricating oil will be discharged into the water-absorbing sponge 21 for storage through the action of the one-way valve 13, the double-headed joint 14 and the hose. When the lubricating oil is discharged into the water-absorbing sponge 21, it will be distributed under the action of the brush 22 On the outside of the brush 22, when the steel cable 23 passes through the brush 22, the outside of the steel cable 23 will be coated to ensure the safety of the steel cable 23 during use. At the same time, in the process of winding or lowering the steel cable 23, the steel cable 23 will also pass through the inside of the mounting column 25, and the mounting column 25 inside the mounting column 25 will push the measuring block 27 to make contact between the measuring block 27 and the steel cable 23. When the surface of the steel cable 23 is damaged, the measuring block 27 will slide under the thrust of the second pressure spring 28. When the measuring block 27 slides, the sliding of the measuring block 27 will further drive the connecting rod 26 to slide, and then drive the connecting plate 29 to slide, so that the connecting plate 29 and the paddle 31 are in contact. When the connecting plate 29 and the paddle 31 are in contact, the alarm 30 will be energized, and then an alarm will be generated to remind the staff that the steel cable 23 is damaged and needs to be replaced.
