DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Figure 1 and Figure 2 As shown, the present embodiment provides an automatic rail unloading device, comprising a support plate 1, a cutting mechanism and a fixing mechanism. A protective shell 2 is provided on the surface of the support plate 1. Figure 2 As shown, the cutting mechanism includes a moving plate 3, a telescopic rod 4, a driving motor 5 and a cutting blade 6. The moving plate 3 is arranged inside the protective shell 2, the telescopic rod 4 is arranged on the top of the protective shell 2, the bottom of the telescopic rod 4 is fixedly connected to the surface of the moving plate 3, the driving motor 5 is arranged on the lower surface of the moving plate 3, the cutting blade 6 is keyed to the output end of the driving motor 5, and a nozzle 7 is also provided on the lower surface of the moving plate 3, and the nozzle 7 is used to cool the cutting blade 6.

[0023] See also Figure 3 The fixing mechanism includes a sleeve 8, a connecting plate 9 and a fixing seat 10. The sleeve 8 is fixedly connected to the lower surface of the movable plate 3. The connecting plate 9 is movably arranged inside the sleeve 8. The lower surface of the connecting plate 9 and the fixing seat 10 are detachably connected.

[0024] The telescopic rod 4 can drive the movable plate 3 to move up and down in the protective shell 2. When the movable plate 3 moves up and down, it drives the driving motor 5 and the sleeve 8 at the bottom to move, and the driving motor 5 cuts the rail. The fixed seat 10 fixes the rail. The position of the fixed seat 10 is lower than the lowest point of the cutting blade 6. When cutting, the fixed seat 10 first contacts the rail to fix the rail. The movable plate 3 continues to move downward, and the connecting plate 9 will be pushed back into the sleeve 8, thereby shortening the distance that the connecting plate 9 extends, so that the cutting blade 6 contacts the rail and cuts the rail. During the cutting process, the nozzle 7 sprays cooling water on the cutting blade 6 to cool the cutting blade 6 and reduce the deformation of the cutting blade 6 caused by high temperature.

[0025] In this embodiment, see Figure 4 The connecting plate 9 is connected to the fixing seat 10 through a clamping mechanism. A positioning groove 11 is provided on the lower surface of the fixing seat 10. The clamping mechanism includes a connecting block 12 and a connecting groove 13. The connecting block 12 is fixedly connected to the lower surface of the connecting plate 9. The connecting groove 13 is provided on the upper surface of the fixing seat 10. The connecting groove 13 and the connecting block 12 are slidably connected. A compression spring 14 is provided inside the sleeve 8. The lower surface of the compression spring 14 is fixedly connected to the upper surface of the connecting plate 9. The compression spring 14 is used to push the connecting plate 9 to move downward.

[0026] The fixing seat 10 can be inserted into the bottom of the connecting plate 9 from the side and fixed together with the connecting plate 9. The fixing seat 10 can be easily replaced and the width of the positioning groove 11 can be adjusted using the clamping mechanism to adapt to different types of rails. In the process of the movable plate 3 moving downward, the fixing seat 10 is stuck on the rail and pushes the connecting plate 9 upward, so that the connecting plate 9 squeezes the compression spring 14 in the sleeve 8, shortening the extended distance of the connecting plate 9, so that the cutting blade 6 can cut the fixed rail. The fixing of the rail by the fixing seat 10 can reduce the shaking of the rail and improve the verticality during the cutting process.

[0027] In this embodiment, a water pipe 15 is provided on the top of the protective shell 2, one end of the water pipe 15 is threadedly connected to the water inlet end of the nozzle 7, a screen 16 is provided on the surface of the support plate 1, and a water collecting tray 17 is provided on the lower surface of the support plate 1. The water collecting tray 17 is used to collect waste water generated by cutting, a support leg 18 is provided at the bottom of the support plate 1, and a conveying roller for conveying the rail is provided on one side of the support plate 1.

[0028] The water pipe 15 conveys cooling water into the protective shell 2 and is connected to the nozzle 7. The cooling water is sprayed from the nozzle 7 to cool the cutting blade 6. The cooled water directly flows down through the screen 16 into the water collecting tray 17, and then is discharged from the bottom of the water collecting tray 17 for reuse. The metal debris generated by cutting will remain on the surface of the screen 16 and can be recycled. The conveying roller is used to drive the rail to move, reducing the intensity of manual labor.

[0029] When the automatic rail unloading device of this embodiment is used to unload rails:

[0030] First, place the rail on the conveyor roller, which drives the rail to move to one side. After moving the required length, the telescopic rod 4 drives the movable plate 3 to move downward. During the downward movement of the movable plate 3, the fixed seat 10 fixes the rail to reduce the shaking of the rail. The driving motor 5 drives the cutting blade 6 to rotate and cut the rail. While cutting, the nozzle 7 sprays cooling water to cool the cutting blade 6. After the cutting is completed, the telescopic rod 4 is reset, the fixed seat 10 and the rail are separated, and the conveyor roller conveys the rail out.
