DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 2 The utility model provides an embodiment: an automatic unloading device for plastic-coated steel pipes, comprising multiple machine feet 1, the top ends of the multiple machine feet 1 on the left are fixedly connected with a slope box 2, the machine feet 1 here play a supporting and fixing role for the slope box 2, the top left side of the slope box 2 is fixedly connected with a feed port 3, the front and rear ends of the feed port 3 are fixedly connected with a support plate 4, the feed port 3 here is used to pour in the steel pipes that need to be unloaded, and the bottom end of the support plate 4 is fixedly connected to the top of the slope box 2.

[0032] Reference Figure 1 The right bottom end of the slope box 2 is fixedly connected to a base 5, and the right side of the base 5 is fixedly connected to the left side of the two right machine feet 1. The bottom end of the inner wall of the base 5 is fixedly connected to a cylinder 6. The base 5 here plays a supporting and fixing role for the cylinder 6. The driving end of the cylinder 6 is fixedly connected to a baffle 7. The cylinder 6 here can push the baffle 7 to move up and down. The left side of the baffle 7 is slidably connected to the left side of the inner wall of the base 5. The top of the baffle 7 is fixedly connected to a slope block 8. The baffle 7 here can drive the slope block 8 to move when it moves;

[0033] Reference Figure 1 The top of the base 5 is fixedly connected to the limit column 9, and the right side of the slope block 1 8 is slidably connected to the left side of the limit column 9. The limit column 9 here plays a limiting role for the slope block 1 8 to ensure that it does a linear motion up and down without deviation. The front and rear ends of the slope block 1 8 are rotatably connected to the connecting rod 10. The middle parts of the two connecting rods 10 are respectively rotatably connected to the front and rear ends of the limit column 9. The other ends of the two connecting rods 10 are rotatably connected to the slope block 2 11. Because of the presence of the connecting rod 10 here, when the cylinder 6 pushes the slope block 1 8 to move up, the slope block 2 11 will move down, and vice versa.

[0034] Reference Figure 1 The left side of the slope block 21 is slidingly connected to the right side of the limit column 9, and the top ends of the two machine feet 1 on the right are fixedly connected to the bottom plate 25. The machine foot 1 here supports and fixes the bottom plate 25. The top of the bottom plate 25 is rotatably connected to a conveying assembly. The conveying assembly includes two side plates 12. The conveying assembly here is used to transport steel pipes. The bottom ends of the two side plates 12 are rotatably connected to the top of the bottom plate 25. The front left side of the front end side plate 12 is fixedly connected to the bottom block 13, and the inner wall of the bottom block 13 is fixedly connected to the motor 14. The bottom block 13 here supports and fixes the motor 14 to maintain its stability during operation.

[0035] Reference Figure 3 , the driving end of the motor 14 is fixedly connected to the main shaft 15, and the outside of the main shaft 15 is fixedly connected to a roller 16. Here, the motor 14 can drive the roller 16 to rotate when it rotates, and the outside of the roller 16 is provided with a crawler 17. The right inner wall of the two side plates 12 is rotatably connected to another main shaft 15. Here, the roller 16 can drive the crawler 17 to transmit when it rotates, thereby transporting the steel pipe. The outer sides of the main shaft 15 are rotatably connected to the inner wall of the side plate 12, and the outside of the other main shaft 15 is fixedly connected to another roller 16. Here, the other main shaft 15 and the roller 16 both play the role of auxiliary transmission;

[0036] Reference Figure 3 The two ends of the roller 16 are rotatably connected to the adjacent sides of the two side plates 12, and the outer part of the other roller 16 is sleeved on the inner wall of the crawler 17. The bottom right end of the conveying assembly is rotatably connected to the lifting assembly. The lifting assembly here is used to adjust the height of the output port of this device to adapt to equipment or containers of different heights. The lifting assembly includes two inner columns 18. The top ends of the two inner columns 18 are rotatably connected to the bottom ends of the two side plates 12, and the outer part of the inner column 18 is slidably connected to the outer column 19. The outer column 19 here plays a supporting and fixing role for the inner column 18.

[0037] Referring to 3, the front end of the front outer column 19 is fixedly connected to a support column 20, and the inner wall of the support column 20 is fixedly connected to a second motor 21. The support column 20 here ensures the stability of the second motor 21 during operation. The driving end of the second motor 21 is fixedly connected to a rotating shaft 22. The outer ends of the rotating shaft 22 are rotatably connected to the inner wall of the outer column 19. The second motor 21 here can drive the rotating shaft 22 to rotate when started. The outer ends of the rotating shaft 22 are fixedly connected to a gear 23. The rotating shaft 22 here can drive the gear 23 to rotate when it rotates;

[0038] Reference Figure 3The external rotation of the gear 23 is connected to the inner wall of the outer column 19, and the right side of the inner column 18 is fixedly connected with a rack 24. The gear 23 and the rack 24 are meshed. Because the rack 24 and the gear 23 are meshed here, the gear 23 will drive the rack 24 to move up and down when it rotates, thereby driving the inner column 18 to move up and down, realizing the height adjustment of the output port of this device.

[0039] Working principle: The staff can first put the steel pipe that needs to be unloaded into the feed port 3. The support plate 4 here plays a supporting role for the feed port 3. Then the steel pipe will roll along the slope box 2 to the gap between the slope block 1 8 and the limit column 9. At this time, the cylinder 6 on the base 5 can be started. The cylinder 6 will push the baffle 7 to move up, thereby pushing the slope block 1 8 to move up. At this time, it returns to drive the connecting rod 10 to rotate, so that the slope block 2 11 falls, thereby pushing the steel pipe to slide into the gap between the slope block 2 11 and the two side plates 12. Because the cylinder 6 is continuously running, when the slope block 2 11 rises again, the steel pipe can be pushed to the surface of the crawler 17. At this time, the motor 14 on the inner wall of the bottom block 13 is started. The motor 14 drives the main shaft 15 and the roller 16 to rotate, thereby driving the crawler 17 to transmit, so that the crawler 17 can unload the steel pipe into the corresponding container or equipment.

[0040] If the height of the equipment at this time does not match this device, the motor 21 inside the support column 20 can also be started. At this time, the motor 21 drives the rotating shaft 22 to rotate, thereby driving the gear 23 to rotate. At this time, the gear 23 and the rack 24 are engaged, so it will drive the inner column 18 to move upward, thereby achieving the purpose of adjusting the height of the output port of this device so that it can be aligned with the container that needs to be unloaded or the input port of the equipment.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
