Description

Technical Field

[0001] The utility model relates to the field of welding mold devices, in particular to a welding mold device for a bottom bracket of a rotor tipping machine roller device. Background Art

[0002] As we all know, a rotor tipper refers to a large-scale mechanical equipment used to tip and unload bulk materials from railway open wagons. It is a loading and unloading machine that can flip or tilt rail vehicles to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. The principle of a rotor tipper is to flip the wagon with the body positioned well to 165 degrees after the tipping conditions are met, unload the coal on each wagon into the coal hopper, and feed it to the belt by the coal feeder. The unloaded coal is transported to the coal yard or raw coal bin by the ground belt conveyor, where the in-and-out car end disc is an important force-bearing component for flipping the wagon. The end disc of the rotor tipper involved in the utility model mainly adopts a C-shaped opening structure. After the end disc is welded and formed, the outer ring has a regular shape, which is an open circle with a diameter of generally about 7600mm. The inner ring has an irregular shape, which is a combination of half a circular arc part and half a straight line part. It is also an open structure, such as Figure 3 ( Figure 4 As shown in 17), each end plate of the rotor tipper needs to be equipped with a roller device at the bottom. The roller device is mainly composed of a round roller ( Figure 4 19) of the balance beam ( Figure 4 18 in), bottom bracket ( Figure 4 The bottom bracket is composed of three parts, which is used to support the end plate body to flip at a certain angle. The bottom bracket is the main force-bearing component of the end plate body, such as Figure 4 , 5 , 6, its structure consists of an upper cover plate ( Figure 5 21) and the left vertical board ( Figure 5 22), straight rib plate ( Figure 5 23) and the lower cover ( Figure 5 24), middle web ( Figure 5 25 in), diagonal stiffeners ( Figure 5 26), right vertical board ( Figure 5 27) in it are welded together, where the upper and lower cover plates are 20×560×5360mm in size; the middle web plate is 20×360×5360mm in size; the front and rear symmetrical reinforcing rib plates (straight rib plates) are 20×270×360mm in size; the front and rear symmetrical reinforcing rib plates (oblique rib plates) are 20×270×367mm in size; the left and right vertical plates are 20×380×560mm in size.

[0003] At present, the bottom bracket is manufactured by cutting each component separately according to the design dimensions on the drawings. After cutting, the center line is first drawn on the lower cover along the length direction, and the web position lines are drawn on both sides of the center line of the lower cover according to the thickness of the web. The web is fixed by spot welding. Then, according to the design on the drawings, 20 straight rib plates and 8 oblique rib plate position lines are drawn on the left and right sides of the web and the front and back with the vertical center line of the web as the reference. They are fixed by spot welding, and then the left and right vertical plates are fixed by spot welding. Finally, the connection positions of each plate are continuously welded.

[0004] During the welding process of the bottom bracket, when the end plate falls on the stick, the ribs at certain positions below the upper cover of the bottom bracket will not be properly supported, resulting in uneven force on certain parts, especially when the end plate is tipping over a fully loaded car, the upper cover of the bracket will bear the force of low-speed and heavy-load rolling.

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.

[0025] See also Figure 1-6A welding mold device for the bottom bracket of a rotor dumper roller device comprises a channel steel 1, a pipe sleeve 2, a rectangular tube 5, a threaded cylinder 7 and a first roller 9. The two channel steels 1 are symmetrically arranged, and the plurality of pipe sleeves 2 are located between the two channel steels 1. The two rectangular tubes 5 are symmetrically arranged. The bottoms of the two rectangular tubes 5 are provided with a pipe shaft 3. Both ends of the pipe shaft 3 penetrate the bottom ends of the rectangular tubes 5. The rectangular tubes 5 are provided with a first square plate 6 and a threaded cylinder 7 penetrating the first square plate 6 and the rectangular tube 5. The threaded cylinder 7 is fixed on the rectangular tube 5. The upper end of the rectangular tube 5 is provided with a second square plate 16 and a first roller 9.

[0026] In this structure, both ends of the tube shaft 3 are fixed to the lower end of the rectangular tube 5 by means of the first nut 4, so that the tube shaft 3 can be easily assembled.

[0027] Furthermore, the first square plate 6 is welded to both sides of the rectangular tube 5, and two second nuts 8 are provided on the threaded cylinder 7. The two second nuts 8 are respectively located on the outer sides of the two first square plates 6. The second square plate 16 is welded to the upper end of the rectangular tube 5. The welding method can make the first square plate 6 and the second square plate 16 installed more firmly.

[0028] In this structure, the distance between the two third nuts 10 and the first roller 9 is 1MM, and the distance between the two fourth nuts 13 and the second roller 12 is 1MM, which can prevent large friction between the first roller 9 and the third nut 10, and prevent large friction between the second roller 12 and the fourth nut 13, so that the first roller 9 and the second roller 12 can rotate more smoothly.

[0029] The two ends of the pipe shaft 3 are threaded at appropriate positions, and the middle position in contact with the sleeve is the optical axis. The pipe shaft 3 is inserted into the pipe sleeve 2, and the channel steel 1, the pipe sleeve 2, and the pipe shaft 3 are connected by the first nut 4. The channel steel 1, the rectangular tube 5, the first square plate 6, and the second square plate 16 are fixed by welding; the threaded cylinder 7 is inserted into the circular hole of the first square plate 6, and threads are processed at appropriate positions at both ends of the first fixed shaft 11. The middle position in contact with the first roller 9 is the optical axis. After the first fixed shaft 11 is inserted into the second square plate 16, the two are fixed by the third nut 10. After the first roller 9 penetrates the first fixed shaft 11 and contacts the third nut 10 below it, the upper third nut 10 is screwed into the first fixed shaft 11 , prevent the first roller 9 from moving upward, but leave a gap of about 1mm to facilitate the smooth rotation of the first roller 9; the threaded cylinder 7 is welded and fixed to the second fixed shaft 14; threads are processed at appropriate positions on both ends of the second fixed shaft 14, and the middle position and the contact position with the second roller 12 are the optical axis. The fourth nut 13 is screwed into the second fixed shaft 14. After the second roller 12 penetrates the second fixed shaft 14 and contacts the fourth nut 13 below it, the upper fourth nut 13 is screwed into the second fixed shaft 14 to prevent the second roller 12 from moving upward, but leave a gap of about 1mm to facilitate the smooth rotation of the second roller 12; the conical block 15 is screwed into the threaded hole at the upper end of the second fixed shaft 14.

[0030] In this device, the pipe sleeve 2 can rotate 360° in situ on the pipe shaft 3; the threaded cylinder 7 can move left and right in the rectangular tube 5 and the circular hole of the first square plate 6. Since the second fixed shaft 14 is welded on the other end of the threaded cylinder 7, the second roller 12, the fourth nut 13, the second fixed shaft 14, and the conical block 15 can also move left and right with the threaded cylinder 7; the second roller 12 can rotate 360° in situ on the second fixed shaft 14; since the conical block 15 penetrates into the threaded hole of the second fixed shaft 14, the conical block 15 can move left and right in the threaded hole of the second fixed shaft 14; the first roller 9 can rotate 360° in situ on the first fixed shaft 11. Except for the above parts, the rest of the parts are fixed in their original positions.

[0031] The combination of the channel steel 1, the pipe sleeve 2, the pipe shaft 3 and the first nut 4 can not only support the lower cover plate, the middle web plate and the upper cover plate of the bottom bracket of the roller device, but also make it convenient to move away from the device after the three are assembled on the welding mold device; when the left and right positions of the second fixed shaft 14 are appropriate, the rectangular tube 5 to the second nut 8 are mainly used for fixing, and the second roller 12, the fourth nut 13 and the second fixed shaft 14 are combined together. The second roller 12 can be used to fix the middle web plate to prevent it from shaking left and right, ensure that it is perpendicular to the lower cover plate, and detect the flatness of the web plate at the same time. After the assembly is completed, the second roller 12 is rotated to facilitate the assembly and removal of the welding mold device; when the position of the middle web is fixed, the conical block 15 of the welding mold device can be used to accurately determine the position of the straight rib plate of the bottom bracket; when the position of the first roller 9 is properly installed, it is fixed by the third nut 10, the first fixed shaft 11, and the second square plate 16. The first roller 9 can mainly fix the upper cover plate of the bracket device to prevent it from shaking left and right. In addition, the first roller 9 can also be used to detect the straightness of the side of the upper cover plate. After the upper cover plate is assembled, the first roller 9 is rotated to facilitate the assembly and removal of the welding mold device.

[0032] (1) Figure 1 As shown, first, weld and fix the channel steel 1 to the ground assembly platform. The two pieces of channel steel 1 must be parallel to ensure an inner spacing of 562 mm. Take the center line of position K as the reference (this position line is the center line of the bottom bracket). According to the design requirements of the drawing, the bottom of the straight rib plate and the inclined rib plate in contact with the bottom cover of the bottom bracket are installed with pipe sleeves 2 and pipe shafts 3. Be sure to ensure that all pipe sleeves 2 are on the same horizontal plane, and use the first nut 4 to penetrate the circular hole on the side of the channel steel 1 to fix the pipe sleeve 2, pipe shaft 3 and the channel steel 1. In order to ensure that the lower cover is easier to move on the pipe sleeve 2, two sets of pipe sleeves 2, pipe shafts 3 and first nuts 4 can be installed between the H position and the G position.

[0033] (2) According to Figure 1 First, weld the channel steel 1 and the rectangular tube 5 at the marked position to ensure the verticality of the rectangular tube, weld the first square plate 6 and the rectangular tube 5, and the first square plate 6 should be symmetrical on the front and back sides of the rectangular tube 5. The rectangular tube 5 at the G and H positions is not welded with the first square plate 6. Then, according to the drawing, draw the position line of the center line of the straight rib plate thickness on the outer first square plate 6, and draw the side thickness contour line of the oblique rib plate on the inner side of the G and H positions.

[0034] (3) Select two holes with a diameter of 17 mm on the position line of the thickness center line of the straight rib plate of the outer first square plate 6, drill through the inner and outer first square plates 6 and the rectangular tube 5, assemble the channel steel 12, the fourth nut 13, the second fixed shaft 14, and the conical block 15. After assembly, keep them perpendicular to the threaded cylinder 7 and the channel steel 15 must be parallel to the axial center line of the threaded cylinder 7 and coplanar. This plane is perpendicular to the horizontal plane, and weld the threaded cylinder 7 and the channel steel 14.

[0035] (4) Insert one end of the threaded cylinder 7 through the upper and lower circular holes of the inner first square plate 6. After this end is exposed from the outer first square plate 6, fix it with the second nut 8. Install the first roller 9, the third nut 10, the first fixed shaft 11, and the second square plate 16 to ensure that the gear spacing between the inner sides of the first roller 9 is 562 mm.

[0036] (5) Place the lower cover plate of the bottom bracket steadily on the pipe sleeve 2 of the welding mold device until the left end of the lower cover plate is flush with the leftmost short channel steel of the device. The width of the lower cover plate is 560 mm. Observe the side and bottom surfaces of the lower cover plate. If there is local extrusion between the side surface and the device during normal placement, and there is a large gap between the bottom surface of the lower cover plate and the pipe sleeve 2, it means that the local position of the lower cover plate is out of tolerance and deformed after cutting. The position must be marked and handled in time.

[0037] (6) Since the thickness of the middle web is 20mm, first draw a center line on the lower cover along the length direction based on this data, and draw lines 11mm on each side of the center line. Then adjust the threaded cylinder 7 of the device so that the closest point between the inner sides of the left and right rollers of the channel steel 12 falls on the drawn line on the projection of the lower cover. At this time, the distance between the closest points between the inner sides of the left and right rollers is 22mm. Finally, slowly feed the middle web into the middle of the left and right rollers of the channel steel 12 so that its leftmost end is flush with the leftmost end of the lower cover and ensure that the two are vertical, and then spot weld it to fix it. During the feeding process, observe the contact between the middle web and the rollers of the channel steel 12. If extrusion occurs or the gap is too large, and it cannot be solved after adjustment, it means that the middle web is partially deformed and needs to be marked and handled in time.

[0038] (7) Use the channel steel 15 to determine two points on the middle web and draw a straight line. This line is the center line of the straight rib thickness. Using this line as a reference, return 10 mm on both sides to obtain the straight rib thickness position line. Figure 6 The rectangular tube at G and H positions 5 is designed with the outline of the inclined rib position on the inner side of the rectangular tube according to the drawing, such as Figure 7 As shown, align one end of the inclined rib plate with the outline of the position drawn on the rectangular tube 5, keep it perpendicular to the lower cover plate, and the contact point between the other end and the middle web is the position of the thickness outline of the inclined rib plate, and draw a line.

[0039] (8) Place the upper cover on the middle web and slowly move it along the inner side of the first roller 9 of the device until the left and right ends of the upper cover are aligned with the left and right ends of the middle web. If there is local squeezing between the side and the device during normal placement, it means that the size of the local position of the upper cover is out of tolerance after unloading. The position must be marked and handled in time.

[0040] (9) Move the bottom bracket out of the device, and according to the thickness position lines of the straight ribs and the oblique ribs marked on the middle web, the left and right straight ribs and the oblique ribs can be quickly spot welded and fixed according to the position lines, and then the upper and lower cover plates, straight ribs and oblique ribs are continuously welded to form. For the production of the next bottom bracket, except that the straight ribs and the oblique ribs need to be re-determined and marked on the middle web using the device channel steel 15, the other parts of the device do not need to be moved, and the upper and lower cover plates of the bottom bracket and the middle web can be directly assembled and tested.
