[0002] When a monorail crane lifts coal for sampling and testing underground, a hub is needed as the center for storing and releasing the wire rope. After prolonged use, dust and impurities can easily accumulate. If not cleaned in time, these impurities may block the hub's channels, affecting the normal winding and unwinding of the wire rope. The presence of dust and impurities will also increase the friction between the wire rope and the hub, leading to accelerated wear of the wire rope and shortening its service life. Manual cleaning is time-consuming and laborious during underground work, increasing the difficulty of the work for underground workers. Utility Model Content

[0003] The purpose of this invention is to provide a monorail auxiliary transportation device with a long service life to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides a long-service-life monorail auxiliary transportation device, including an I-beam. A hoisting assembly is installed on the I-beam. The hoisting assembly includes a U-shaped track connector, a wire rope connector, and a wire rope fixing component. The U-shaped track connector is fixedly connected to the middle section of the I-beam. The wire rope connector and the wire rope fixing component are installed at both ends of the lower surface of the I-beam. Two rotating columns are installed on the inner side wall of the lower opening of the U-shaped track connector. Each of the two rotating columns and the wire rope connector is rotatably connected to a pulley. A wire rope is sleeved on the pulley. The initial end of the wire rope is fixedly connected to the wire rope fixing component.

[0005] A wire take-up assembly and a dust removal assembly are installed below the I-beam. The wire take-up assembly includes a wire collector located below the wire rope connector.

A centrifugal block is installed below the filter screen, and a rotating shaft is fixedly connected to the centrifugal block. A motor is installed at the end of the rotating shaft away from the outer side wall of the sleeve.

[0006] Furthermore, support frames are installed on both sides of the bottom of the I-beam. The support frames are made of triangular stainless steel. An mounting plate is installed on the side of one of the support frames away from the U-shaped track connector. Two protrusions are installed on the side of the mounting plate away from the support frame. The hub is rotatably connected between the two protrusions.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] See Figure 1 and Figure 3 as well as Figure 5 As shown, a long-service-life monorail auxiliary transportation device includes an I-beam 1, on which a hoisting assembly is installed. The hoisting assembly includes a U-shaped track connector 2, a wire rope connector 28, and a wire rope fixing component 5. The U-shaped track connector 2 is fixedly connected to the middle section of the I-beam 1. The wire rope connector 28 and the wire rope fixing component 5 are installed at both ends of the lower surface of the I-beam 1. A rotating column 29 is installed on the inner side wall of the lower opening of the U-shaped track connector 2. There are two rotating columns 29. Both rotating columns 29 and the wire rope connector 28 are rotatably connected to pulleys 30. A wire rope 4 is sleeved on the pulley 30. The initial end of the wire rope 4 is fixedly connected to the wire rope fixing component 5.

[0025] A wire take-up assembly and a dust removal assembly are installed below the I-beam 1. The wire take-up assembly includes a wire collector 13, which is located below the wire rope connector 28. The dust removal assembly includes a mounting frame 25 installed below the wire collector 13. A vertical channel is opened inside the mounting frame 25, and a sleeve 21 is installed in the channel. A negative pressure fan 19 is installed on the top of the sleeve 21. A filter screen 20 is installed on the lower inner wall of the sleeve 21. A collection tray 26 is installed at the bottom of the sleeve 21. A through groove matching the sleeve 21 is opened above the collection tray 26. A centrifugal block 24 is installed below the filter screen 20. A rotating shaft 22 is fixedly connected to the centrifugal block 24. A motor 23 is installed at the end of the rotating shaft 22 away from the outer wall of the sleeve 21.

[0026] In practical implementation, the U-shaped track connector 2 is designed in a U-shape to fit tightly against the middle section of the I-beam 1 and is securely fixed with bolts. Two rotating columns 29 installed on the lower inner wall of the U-shaped track connector 2 provide a mounting base for the pulley 30, allowing the wire rope 4 to slide smoothly during transportation. Wire rope connectors 28 are installed at both ends of the lower surface of the I-beam 1 to connect and support the pulley 30 and the wire rope 4, and allow the pulley 30 to rotate on the wire rope connectors 28 via bearings. The connector needs to withstand large tensile and frictional forces, so it is usually made of high-strength titanium alloy. The wire rope fixing part 5 is used to fix the initial end of the wire rope 4 to ensure that the wire rope 4 will not fall off or loosen during the lifting process. The pulley 30 is rotatably connected to the U-shaped track connector 2 through the bearing connected to the rotating column 29. When the wire rope 4 is under tension, the pulley 30 can reduce friction and disperse the force, protecting the wire rope 4 from wear. The wire rope 4 is guided by the pulley 30 to realize the lifting and transportation of coal for sampling and testing.

[0027] The hub 13 is located below the wire rope connector 28 and is used to collect and fix the wire rope 4 when hoisting is not required, preventing it from scattering or causing safety hazards. The mounting frame 25 provides a stable installation platform for the ash removal assembly, ensuring its normal operation. The ash removal assembly can suck the coal ash in the area around the hub 13 into the sleeve 21. The sleeve 21 is installed in the mounting frame 25, and the internal space is used to install components such as the negative pressure fan 19, filter screen 20, and centrifugal block 24. The negative pressure fan 19 generates suction to adsorb the coal ash into the collection tray 26. When the negative pressure fan 19 stops working, the filter screen 20 has larger coal ash particles adsorbed on it. When the motor 23 starts, the centrifugal block 24 will rotate at high speed to generate centrifugal force, shaking off the coal ash particles adsorbed on the filter screen 20, which will eventually fall into the collection tray 26. The collection tray 26 can be easily removed and cleaned to keep the ash removal assembly clean and operate efficiently.

[0028] See Figure 1 and Figure 2As shown, support frames 3 are installed on both sides of the bottom of the I-beam 1. The support frames 3 are made of triangular stainless steel. One of the support frames 3 has an installation plate 6 installed on the side away from the U-shaped track connector 2. Two protrusions are installed on the side of the installation plate 6 away from the support frame 3. The hub 13 is rotatably connected between the two protrusions. The end of the wire rope 4 is fixedly connected to the hub 13.

[0029] In the specific implementation process, the support frame 3 is made of triangular stainless steel. This design not only ensures sufficient strength and stability, but also effectively resists corrosion and extends service life. The triangular structure has extremely high stability and can effectively distribute and bear the weight from the lifting components and goods. The support frame 3 is installed on both sides of the bottom of the I-beam 1 to ensure stability and safety during the operation.

[0030] It should be noted that: two protrusions are installed on the side of the mounting plate 6 away from the support frame 3, and the hub 13 is equipped with a rotating shaft 15 at both ends. The rotating shaft 15 is fitted with a bearing, and the two protrusions are rotatably connected to the rotating shaft 15 through the bearing connection. The hub 13 can conveniently retract the steel wire rope 4 when not needed, thereby reducing space occupation and improving safety.

[0031] See Figure 2 and Figure 6 As shown, a large gear 14 is fixedly connected to one end of the hub 13. The large gear 14 is meshed with a small gear 16. The small gear 16 is fixedly connected to a hand crank shaft 17. The hand crank shaft 17 is located below the hub 13 and is rotatably connected between two protrusions. A hand crank handle 18 is installed at the end of the hand crank shaft 17 away from the small gear 16.

[0032] In the specific implementation process, the small gear 16 can rotate with the rotation of the hand crank shaft 17 and drive the large gear 14 to rotate synchronously. The rotation of the large gear 14 will directly drive the rotation of the hub 13. This connection method ensures the accuracy and reliability of power transmission. As part of the transmission system, the main function of the large gear 14 is to amplify the rotational force generated by the hand crank 18 and transmit it to the hub 13. Since the diameter of the large gear 14 is larger than that of the small gear 16, it can achieve the effect of speed reduction and torque increase, making the hand crank operation more labor-saving.

[0033] A flexible guide hose is installed on the side of the large gear 14 near the hub. A rubber soft brush is connected to the flexible guide hose. When the large gear 14 rotates with the hand crank shaft 17, the rubber soft brush connected to the flexible guide hose also rotates. The flexible guide hose provides flexible support and guidance for the rubber soft brush, allowing it to fit closely to the surface of the hub for cleaning. At the same time, the adjustability of the flexible guide hose allows the rubber soft brush to easily avoid obstacles such as the steel wire rope 4, avoiding tangling and damage. It works well with the negative pressure fan 19 to further improve the cleaning effect and effectively remove dust and dirt.

[0034] It should be noted that the hand crank 18 is the interface component between the operator and the transmission system. A damping bearing is connected between the hand crank 18 and the hand crank shaft 17 to prevent the hand crank 18 from rotating uncontrollably. By rotating the hand crank 18, the operator can transfer mechanical energy to the transmission system, thereby realizing the winding and unwinding control of the hub 13 and the wire rope 4.

[0035] It should be noted that several drilled holes are opened around the small gear 16, and a drilled hole matching the small gear 16 is opened on a protrusion. A locking bolt is connected to the thread in the drilled hole. When the hanging rack 11 is not being transported, it needs to be kept stable. The locking bolt can be rotated into the drilled hole to complete the fixation.

[0036] See Figure 4 As shown, the steel wire rope 4 located between the two rotating columns 29 is connected to a connecting shaft 7. An installation block 8 is installed below the connecting shaft 7. A hook 9 is installed at the bottom of the installation block 8. The hook 9 is connected to a lifting ring 10. A hanging frame 11 is fixedly connected to the bottom of the lifting ring 10. There are two hooks 9 and two lifting rings 10. In the specific implementation process, the main function of the connecting shaft 7 is to transfer the tension of the steel wire rope 4 to the hanging frame 11 below and ensure the stability and safety of the hanging frame 11. The installation block 8 is firmly connected to the connecting shaft 7 by bolts. The main function of the installation block 8 is to provide the installation position of the hook 9 and ensure that the hook 9 can stably bear the heavy object.

[0037] The movable end of the collection drawer 26 is equipped with a pull ring 27. In the specific implementation process, the collection drawer 26 has a sliding structure. Rollers are installed on both sides of the bottom of the movable end. By pulling the pull ring 27, the operator can easily take out the dust collected in the collection drawer 26. The bottom of the support frame 3 is equipped with casters 12. In the specific implementation process, the device can move flexibly in the complex environment downhole through the casters 12.

[0038] Working principle:

[0039] Lifting process: The initial end of the wire rope 4 is firmly fixed to the I-beam 1 by the wire rope fixing piece 5. The wire rope 4 passes through two pulleys 30. The pulleys 30 are rotatably connected to the U-shaped track connector 2 through the rotating column 29, allowing the wire rope 4 to slide smoothly during transportation, reducing friction and wear. The end of the wire rope 4 is fixedly connected to the hub 13. When lifting is required, the coal or other heavy objects to be lifted are connected to the lifting frame 11 by operating the hook 9 and the lifting frame 11. The operator can manually or through other power devices pull the wire rope 4. Through the guiding action of the pulleys 30, the lifting and transportation of heavy objects can be realized.

[0040] Cable winding process: When hoisting is not required, by rotating the hand crank 18, the hand crank shaft 17 drives the small gear 16 to rotate, which in turn drives the large gear 14 and the cable collector 13 to rotate synchronously. The rotation of the cable collector 13 winds up and fixes the wire rope 4 to prevent it from falling or causing safety hazards.

[0041] Dust removal process: The dust removal component works below the hub 13. The negative pressure fan 19 generates suction to draw coal ash and other impurities from the area around the hub 13 into the sleeve 21. The impurities are filtered by the filter screen 20. Larger coal ash particles are trapped on the filter screen 20, while clean air is discharged. When it is necessary to clean the coal ash on the filter screen 20, the motor 23 is started, which drives the rotating shaft 22 and the centrifugal block 24 to rotate at high speed. The centrifugal force shakes the coal ash particles off the filter screen 20 and they finally fall into the collection tray 26. The operator can easily remove the collection tray 26 and clean the coal ash inside by pulling the pull ring 27.
