Description

Technical Field

[0001] This utility model relates to the technical field of duct moving pulleys, and in particular to a pulley device that uses a monorail to transport ducts. Background Technology

[0002] Coal mine roadways are generally characterized by narrow spaces, complex slopes, and high dust concentrations. Traditional railcar transportation requires the laying of a large amount of ground track, which is not only costly to maintain but also prone to runaway accidents due to track deformation. Monorails, with their top-suspended design, can avoid ground obstacles and are more suitable for the complex environment of coal mine roadways. However, the pulley system of traditional monorails lacks a height and thickness adjustable structure with sliding blocks and grooves, making it unsuitable for tracks of different thicknesses. Furthermore, there are often no solutions to the impact forces encountered when turning corners, and the bumpy transportation process may cause the transported goods to fall off. In some cases, the pulley assembly may not be able to reset in time when reaching a corner, resulting in low transportation safety performance. Therefore, improvements are needed to address these issues. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Example: See Figures 1 to 5 This utility model discloses a pulley device for moving air ducts using a monorail, comprising a base plate 1. The base plate 1 has symmetrically arranged first grooves at both ends and a second groove in the middle. A first slider 3 is slidably connected inside the first groove. A support plate 2 is fixed to the top surface of the first slider 3. A third groove is vertically arranged inside the support plate 2. Both the first and third grooves have clamping structures. A second slider 9 is slidably connected inside the second groove. The arrangement of the first slider 3, second slider 9, third slider, and the first, second, and third grooves facilitates the sliding of the first slider 3, second slider 9, and third slider along a predetermined trajectory. Springs 15 are installed at both ends of the second slider 9, with the other side of each spring 15 fixed inside the second groove. The arrangement of the second slider 9 and springs 15 helps to buffer impact forces during transportation and improve transportation stability. The clamping structures include components respectively disposed on the bottom surface of the base plate 1. The clamping plates on both sides and the outer sides of the two support plates 2, the upper end of the clamping plate of the bottom plate 1 and one side of the clamping plate of the support plate 2 are provided with pressure plates 12. Multiple pressure plates 12 are respectively placed in the first slide groove and the second slide groove. The setting of the pressure plates 12 and the first slide groove and the third slide groove facilitates the fixing of the adjusted component when adjusting the height. The pressure plates 12 are connected to the clamping plates by fixing bolts 13 and anti-loosening washers 8. The setting of anti-loosening washers 8 and fixing bolts 13 facilitates the prevention of loosening of the device during transportation. The inner support surface of the two support plates 2 is provided with a fixed end plate 6 in the transverse direction. The fixed end plate 6 is slidably connected to the support plate 2 through the third slide groove. The inner side of the fixed end plate 6 is provided with a pulley structure. The lower bottom surface of the second slider 9 is provided with a torsion spring groove 16. A torsion spring 14 is installed inside the torsion spring groove 16. The setting of the torsion spring 14 and the torsion spring groove 16 facilitates the reset of the suspension component that is twisted during transportation. The inner ring of the torsion spring 14 is sleeved with a central shaft, and the lower end of the central shaft is fixedly connected to the suspension component.

[0014] In this utility model, the pulley structure includes movable end plates 7 mounted on fixed end plates 6 by nuts 4 and fixing bolts 13. The movable end plates 7 and fixed end plates 6 facilitate the disassembly of the pulley structure. Another set of fixing bolts 13 are fixedly connected to the inner sides of the two movable end plates 7. A bearing 5 is sleeved on the other set of fixing bolts 13. The bearing 5 and fixing bolts 13 facilitate the clamping of the bearing 5 onto the threaded rod, which functions as a pulley. The suspension assembly includes a hook 10 mounted on the lower end of the central shaft. One end of the hook 10 is hinged to a limiting half-ring 11. The other end of the limiting half-ring 11 is mounted on the other end of the hook 10 by nuts 4 and fixing bolts 13. The hook 10 and limiting half-ring 11 facilitate the limiting of the air duct, preventing the air duct from falling during transportation.

[0015] Working Principle: In the use of this utility model, the base plate 1 is first placed below the monorail track, ensuring that the bearing 5, which is installed inside the movable end plate 7 and connected by another set of fixing bolts 13, can be accurately locked inside the monorail track, thus laying the foundation for the device to move along the track. At this time, the first slider 3, which is slidably connected in the first groove symmetrically opened at both ends inside the base plate 1, the second slider 9, which is slidably connected in the second groove opened in the middle inside the base plate 1, and the slider in the third groove vertically opened inside the support plate 2 (fixed to the top surface of the first slider 3), can slide stably along the predetermined track in the first groove, the second groove, and the third groove, respectively. Then, by using the threaded engagement of the fixing bolts 13 and the nuts 4, the pressure plates 12 (set at the upper end of the clamping plates on both sides of the bottom surface of the base plate 1 and one side of the clamping plate on the outer side of the support plate 2) placed in the first groove and the third groove, respectively, press against the corresponding grooves, and fix the components through friction, so that the device can adapt to monorail tracks of different thicknesses and meet diverse usage needs. The duct to be transported is then secured to hook 10 (installed at the lower end of the central shaft, with a torsion spring 14 installed inside the torsion spring groove 16 on the lower surface of the second slider 9) using nut 4 and fixing bolt 13. The other end of the limiting half-ring 11, hinged to one end of hook 10, is then installed on the other end of hook 10, thus limiting and fixing the duct. This effectively prevents the duct from falling due to bumps during transport, improving transport safety. During duct transport, when the duct encounters impact at a track corner, the springs 15 installed at both ends of the second slider 9 (the other side is fixed inside the second groove) undergo elastic deformation, mitigating the impact and ensuring more stable duct movement. Simultaneously, the torsion spring 14 on the central shaft connected to hook 10 can reset the tortuous suspension components (including the central shaft, hook 10, and limiting half-ring 11) during transport, further maintaining the overall stability of the device. Furthermore, the pressure plate 12 and... The clamping plates are connected by fixing bolts 13 and anti-loosening washers 8. The anti-loosening washers 8 can effectively prevent the device from loosening during transportation. The movable end plate 7, which is installed on the fixed end plate 6 (which is horizontally set on the inner support surface of the two support plates 2 and is slidably connected to the support plate 2 through the third slide groove) by nuts 4 and fixing bolts 13, also provides convenience for the subsequent disassembly and maintenance of the pulley structure. After the air duct is transported to the designated position, first unscrew the fixing bolts 13 and nuts 4 at one end of the limiting half ring 11, open the limiting half ring 11, and remove the air duct from the hook 10 to complete the unloading of the air duct. If it is necessary to store the device afterward, the fixing bolts 13 at the first slide groove and the third slide groove can be loosened to release the pressure plate 12 from the slide groove. Then, the first slider 3, the second slider 9 and related components are reset. Finally, the base plate 1 is removed from under the monorail. The entire process of using the device is now complete. This process significantly improves the safety and efficiency of air duct transportation through the synergistic effect of the various structures.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be covered within the protection scope of the present utility model.
