Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production, and in particular to a waste steel pipe screening device. Background Technology

[0002] Circular welded steel pipes are made by bending steel strips or plates into a circle and then welding them together. The end of the steel strip needs to be welded to the beginning of the next steel strip. Steel pipes made from these end-to-end steel strips are called scrap steel pipes. After the steel pipes are cut into evenly spaced sections, they are conveyed to a designated location for packaging. During the conveying process, the scrap steel pipes need to be screened and removed. Currently, when removing scrap steel pipes from the conveying device, an overhead crane is used to hoist the pipes onto a scrap pipe storage rack. Workers need to secure the hoisting ropes to the pipes, which is inconvenient and inefficient. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be described in further detail below.

[0018] Reference Figures 1-5This utility model discloses a waste steel pipe screening device, including a support component 1, a conveying component 2 and a storage rack 3. The storage rack 3 includes a plurality of parallel and spaced crossbars 31. The bottom of each crossbar 31 is fixed with a first support leg 32. The bottom of each crossbar 31 is fixed with a connecting rod 33, and the connecting rod 33 fixes the plurality of crossbars 31 together.

[0019] The support assembly 1 includes a first support frame 11 and a first conveying roller 12. The first support frame 11 includes a support block 111 and a first support plate 112. The first support plate 112 is fixed to the bottom of the support block 111. A first rotating shaft 13 is fixed to both ends of the first conveying roller 12. A first mounting block 14 is provided on both sides of the first conveying roller 12. The first mounting block 14 is fixed to the support block 111. The first rotating shaft 13 is rotatably connected to the first mounting block 14. Multiple first support frames 11 are arranged sequentially along the conveying direction of the steel pipe.

[0020] The conveying assembly 2 includes a second support frame 21 and a second conveying roller 22. A second mounting block 23 is fixed on the second support frame 21. Second rotating shafts 24 are fixed to both ends of the second conveying roller 22, and the second rotating shafts 24 are rotatably connected to the second mounting blocks 23. Adjacent second conveying rollers 22 are connected by a chain 25 and a sprocket 26. A first motor 27 is fixed on one of the second support frames 21, and the first motor 27 drives the second conveying roller 22 to rotate. Through the transmission of the sprocket 26, the second conveying roller 22 drives the remaining second conveying rollers 22 to rotate, thereby conveying the steel pipe onto the first conveying roller 12.

[0021] Each crossbar 31 is equipped with a pipe-pushing assembly 4 on the side near the first support frame 11. The pipe-pushing assembly 4 can push the scrap steel pipes on the first conveyor roller 12 onto the crossbar 31. The pipe-pushing assembly 4 includes a first lever 41 and a third rotating shaft 42. The third rotating shaft 42 is rotatably connected to the crossbar 31, and one end of the first lever 41 is fixed to the third rotating shaft 42. A servo motor 43 that drives the third rotating shaft 42 to rotate is fixed on the side wall of the crossbar 31. When the first lever 41 is in the horizontal position, the position of the first lever 41 is lower than the lowest point of the steel pipe on the first conveyor roller 12, ensuring that the scrap steel pipe can be pushed from the first conveyor roller 12 onto the crossbar 31 when the first lever 41 rotates.

[0022] The top surface of the crossbar 31 is inclined, with the side of the crossbar 31 closer to the first support frame 11 being higher and the side of the crossbar 31 farther from the first support frame 11 being lower. When a steel pipe is placed on the crossbar 31, the steel pipe rolls towards the lower side of the top surface of the crossbar 31. A stop bar 34 is fixed to the side of the crossbar 31 away from the first support frame 11, and the stop bar 34 is fixed to the top surface of the crossbar 31. In this embodiment, there are a total of 4 crossbars 31, and the two crossbars 31 located at the center are each equipped with a gathering component 5. When the scrap steel pipes are stacked, the gathering component 5 gathers the steel pipes on the crossbar 31 towards the stop bar 34, and then bundles them together.

[0023] The converging assembly 5 includes a converging plate 51, a fourth rotating shaft 52, a rotating rod 53, and a first cylinder 54. The converging plate 51 is located on one side of the crossbar 31. The fourth rotating shaft 52 passes through the crossbar 31 and is rotatably connected to it. One end of the converging plate 51 is fixed to the fourth rotating shaft 52. The top of the rotating rod 53 is fixed to the end of the fourth rotating shaft 52 away from the converging plate 51. The tail of the first cylinder 54 is hinged to the side wall of the first support leg 32. The piston rod of the first cylinder 54 is hinged to the side of the rotating rod 53 away from the fourth rotating shaft 52. When the steel pipe rolls on the crossbar 31, the converging plate 51 is in a horizontal state, and the upper surface of the converging plate 51 is lower than the upper surface of the crossbar 31, thus not affecting the movement of the steel pipe toward the stop bar 34.

[0024] When it is necessary to gather the steel pipes, the first cylinder 54 is activated, the piston rod of the first cylinder 54 extends, and pushes the bottom of the rotating rod 53 to rotate upward, thereby driving the gathering plate 51 to rotate through the fourth rotating shaft 52. The end of the gathering plate 51 away from the fourth rotating shaft 52 rotates upward, thereby gathering part of the steel pipes on the crossbar 31 towards the stop bar 34. After the gathering plate 51 rotates 90 degrees, the steel pipes between the gathering plate 51 and the stop bar 34 are bound together.

[0025] A second cylinder 55 is fixed below the gathering plate 51. The second cylinder 55 is located away from the gathering plate 51 and away from the fourth rotating shaft 52. The piston rod of the second cylinder 55 passes through the gathering plate 51. When the gathering plate 51 is rotated, the piston rod of the second cylinder 55 extends, which facilitates the gathering of the steel pipes supported by the gathering plate 51 to the stop bar (34), reducing the risk of the steel pipes supported by the gathering plate 51 slipping to the side away from the stop bar 34.

[0026] Multiple steel pipe conveying assemblies 6 are arranged on the side of the first support frame 11 away from the crossbar 31. The steel pipe conveying assemblies 6 convey qualified steel pipes that have been conveyed to the first conveying roller 12. The steel pipe conveying assembly 6 includes a conveying chain 61, a conveying sprocket 62, and a second lever 63. The conveying chain 61 and the conveying sprocket 62 engage for transmission.

[0027] A second support plate 64 is provided on both sides of the conveyor sprocket 62. The conveyor sprocket 62 is rotatably connected between the two second support plates 64. A second motor 65 for rotating the conveyor sprocket 62 is fixed on one of the second support plates 64. A plurality of second levers 63 are fixed on the conveyor chain 61. The plurality of second levers 63 are evenly distributed on the conveyor chain 61. When the conveyor chain 61 rotates, it can move qualified steel pipes from the first conveyor roller 12 onto the conveyor chain 61.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
