[0037] Reference below Figures 1-8 An automatic tilting device 100 according to an embodiment of the present invention will be described.

[0038] like Figures 1-8 As shown, the automatic tipping device 100 according to the embodiment of the present invention includes: a hook mechanism 10, a connecting mechanism 20, a rotating mechanism 30 and a hook mechanism 40, the hook mechanism 10 includes a first hook 11 and a second hook 12, the first hook 11 can be raised and lowered, and the second hook 12 can also be raised and lowered, the first hook 11 and the second hook 12 are arranged at intervals, the first hook 11 is used to hook the main hanging shaft 61 of the slag bag, and can realize the transportation of the slag bag; the connecting mechanism 20 is arranged on the second hook 12, and the rotating mechanism 30 is arranged on the side of the connecting mechanism 20 away from the second hook 12 (as shown in FIG. Figure 1 The rotating mechanism 30 is connected to the connecting mechanism 20, and the hook mechanism 40 is arranged on the side of the rotating mechanism 30 away from the connecting mechanism 20 (as shown in the lower side). Figure 1 The hook mechanism 40 is connected to the rotating mechanism 30, and the lifting and lowering of the second hook 12 can drive the lifting and lowering of the hook mechanism 40.

[0039] The hook mechanism 40 includes a hook 41 and a swingable hanging rod 42, wherein the hook 41 is fixed to the lower end of the hanging rod 42 (e.g. Figure 1 The lower end is shown in the figure), so that the hook 41 can hook the side hanging shaft 62 of the slag bag, and then the slag bag can be dumped by the lifting and coordination of the first hook 11 and the second hook 12; the hanging rod 42 can swing during the dumping of the slag bag to prevent the hook 41 from being separated from the side hanging shaft 62, thereby improving the stability of the hook 41 hooking the side hanging shaft 62.

[0040] Among them, the rotating mechanism 30 can drive the hook mechanism 40 to rotate between the first rotation position and the second rotation position. When the hook mechanism 40 is in the first rotation position, the hook 41 can be raised and lowered along with the second hook 12 to hook the side hanging shaft 62, thereby improving the accuracy of the hook 41 hooking the side hanging shaft 62; when the hook mechanism 40 is in the second rotation position, the hook 41 can avoid the slag bag to prevent the hook 41 from interfering with the slag bag, so that the hook 41 can be in a state of being disengaged from the side hanging shaft 62, and the slag bag can be raised and lowered normally along with the first hook 11, which is easy to operate, thereby realizing the automation of the automatic tipping device 100.

[0041] According to the automatic tipping device 100 of the embodiment of the present invention, the rotating mechanism 30 drives the hook mechanism 40 to rotate relative to the connecting mechanism 20, and the hook 41 can be rotated to the second rotation position during the lifting and lowering of the slag bag to avoid the slag bag, and the hook 41 can be rotated to the first rotation position so that the hook 41 hooks the side hanging shaft 62, thereby realizing automatic dumping of the slag bag, reducing the risk of the slag bag dumping operation, ensuring the safety of the staff, and improving work efficiency; by providing the connecting mechanism 20, the rotating mechanism 30 and the hook mechanism 40, the second hook 12 can be hooked to the side hanging shaft 62 of the slag bag through the connecting mechanism 20, the rotating mechanism 30 and the hook mechanism 40, which is conducive to shortening the length of the second hook 12, so as to reduce the probability of the second hook 12 shaking, and the hook 41 can be accurately hooked to the side hanging shaft 62 of the slag bag, thereby improving the stability of the cooperation between the first hook 11 and the second hook 12, and improving the stability of the slag bag dumping.

[0042] In addition, by setting up a rotating mechanism 30 to make the hook mechanism 40 rotate relative to the second hook 12, the hook 41 avoids the outer edge of the slag bag. By adopting the form of a rotating structure, the hook mechanism 30 can be moved by controlling the rotation angle. There is no need to set up rails or other devices to make the first hook 11 and the second hook 12 relatively close or far away, which reduces costs, simplifies the structure, saves space, and has a good automation effect.

[0043] like Figure 1 and Figure 7 As shown, according to some embodiments of the present invention, the automatic tilting device 100 also includes: a guide mechanism 50, the guide mechanism 50 includes a guide plate 51 and a guide groove 52, the guide plate 51 can be arranged on the first hook 11, and the guide groove 52 is arranged on the hook mechanism 40, wherein when the hook mechanism 40 is in the first rotation position, the opening of the guide groove 52 faces the guide plate 51, so that the guide plate 51 can be plugged into and matched with the guide groove 52, that is, the guide mechanism 50 can guide the hook 41 in the process of the hook 41 hooking the side hanging shaft 62, so that the hook 41 can accurately hook the side hanging shaft 62 of the slag bag, ensuring that the automatic tilting device 100 performs a safe and stable tilting operation on the slag bag; when the hook mechanism 40 is in the second rotation position, the guide groove 52 is misaligned with the guide plate 51, so that the hook 41 can avoid the slag bag, thereby improving the stability and safety of the automatic tilting device 100.

[0044] It is understandable that the guide groove 52 with open upper and lower sides can be defined by the guide member, and the guide member can be connected to the hanging rod 42 of the hook mechanism 40 by fasteners such as bolts or screws, and the connection effect is good.

[0045] Of course, under the premise that the guide plate 51 can be inserted into the guide groove 52, the guide plate 51 can also be arranged on the hook mechanism 40, and the guide groove 52 is arranged on the first hook 11.

[0046] As shown in Figure 2 some examples, the upper side of the guide groove 52 (as shown in Figure 2 the upper side) is also provided with a first guide groove 521, and the cross-sectional size of the first guide groove 521 gradually decreases along the direction close to the guide groove 52 (as shown in Figure 2 the direction from top to bottom), that is, the opening of the first guide groove 521 faces upward and presents a downward shrinking trend, so that when the guide plate 51 is inserted into the guide groove 52 from top to bottom, the first guide groove 521 can guide the guide plate 51, improve the accuracy of the hooking of the side hanging shaft 62 of the hook 41, and reduce the influence of the machining and assembly precision on the device, which is conducive to reducing the cost.

[0047] As shown in Figure 2 some examples, the lower side of the guide groove 52 (as shown in Figure 2 the lower side) is also provided with a second guide groove 522, and the cross-sectional size of the second guide groove 522 gradually decreases along the direction close to the guide groove 52 (as shown in Figure 2 the direction from bottom to top), that is, the opening of the second guide groove 522 faces downward and presents an upward shrinking trend, so that when the guide plate 51 is inserted into the guide groove 52 from bottom to top, the second guide groove 522 can guide the guide plate 51, improve the accuracy of the hooking of the side hanging shaft 62 of the hook 41, and reduce the influence of the machining and assembly precision on the device, which is conducive to reducing the cost.

[0048] In some examples, the guide plate 51 is arranged on the first hook 11, and the guide plate 51 includes two oppositely arranged guide plates, so that Figure 1 as shown, under the premise that the opening of the guide groove 52 faces the guide plate 51, the second hook 12 and the hook mechanism 40 can be installed to the left side of the first hook 11, or can be installed to the right side of the first hook 11, which is convenient for assembling the automatic tilting device 100, and is convenient for changing the tilting direction of the ladle, and can also balance the gravity center of the first hook 11, improve the stability of the main hanging shaft 61 of the first hook 11 for hooking the ladle, prevent the first hook 11 from being separated from the main hanging shaft 61, and improve the reliability and safety of the device.

[0049] In some examples, the guide groove 52 is arranged on the outside of the hanging rod 42, for example, as shown in Figure 1 the guide groove 52 is arranged on the left side of the hanging rod 42, and the extension direction (as shown in Figure 1 the left-right direction) of the guide groove 52 is perpendicular to the extension direction (as shown in Figure 1The vertical direction is perpendicular to the vertical direction of the upper and lower directions shown in the figure, facilitating the plug-in cooperation of the guide groove 52 and the guide plate 51.

[0051] The extension direction of the rotating shaft 431 is perpendicular to the extension direction of the hanging rod 42 (such as the vertical direction shown in Figure 1 ), after the hook mechanism 40 is turned to the first rotating position, and when the hook 41 hooks the side lifting shaft 62 of the ladle and rises with the second lifting hook 12, the hanging rod 42 can swing to the side away from the ladle (such as the right side shown in Figure 1 ) to balance the forces in all directions in the automatic tilting device 100, thereby ensuring that the hook 41 always hooks the side lifting shaft 62 without external force, reducing the probability of the hook 41 disengaging from the side lifting shaft 62 during the tilting of the ladle, and reducing the probability of the second lifting hook 12 disengaging from the second connecting frame 22, thereby improving the stability and safety of the automatic tilting device 100.

[0052] In some examples, the two ends of the rotating shaft 431 are fixed to the first connecting frame 43 by a baffle, specifically, two baffles are arranged at the two ends of the rotating shaft 431, the two baffles arranged at one end of the rotating shaft 431 are arranged on the opposite sides (such as the upper and lower sides shown in Figure 1 ) of the rotating shaft 431, and are fixedly connected with the first connecting frame 43 by fasteners, and a part of the baffles is inserted into the rotating shaft 431, which can limit the axial movement of the rotating shaft 431, prevent the rotating shaft 431 from moving along its axial direction, and improve the stability of the swinging of the hanging rod 42.

[0053] As shown in Figure 6 , in some examples, the outer end (such as the left and right ends shown in Figure 6 ) of the rotating shaft 431 can be sleeved with a plurality of bearings 432, the inner ring of the bearing 432 is in contact with the outer circumference of the rotating shaft 431, and the outer ring of the bearing 432 is in contact with the inner wall surface of the hanging rod 42, so that the hanging rod 42 can rotate around the axis of the rotating shaft 431, and the frictional resistance of the rotating shaft 431 can be reduced, thereby improving the flexibility of the swinging of the hanging rod 42.

[0054] AsFigure 6 As shown, in some examples, the bearing 432 can be a deep groove ball bearing, which can reduce pressure and align the center, thereby improving the rotation stability of the rotating shaft 431; two bearings 432 can be set at both ends of the rotating shaft 431, thereby improving the load capacity of the rotating shaft 431.

[0055] like Figure 3 As shown, according to some embodiments of the present invention, the connecting mechanism 20 includes a second connecting frame 22 and a first fixed shaft 21, the first fixed shaft 21 is arranged on the second connecting frame 22, the rotating mechanism 30 is connected to the second connecting frame 22, the second hook 12 can hook the first fixed shaft 21, and then the lifting and lowering of the second hook 12 can drive the entire hook mechanism 40 to lift and lower; the rotating mechanism 30 drives the hook mechanism 40 to rotate relative to the second connecting frame 22 to realize the rotation of the rotating mechanism 30 between the first rotation position and the second rotation position, so that the hook 41 can accurately hook the side hanging shaft 62 of the slag bag, and the hook 41 can rotate during the lifting process to avoid the slag bag, thereby improving the safety of the automatic tipping device 100 and facilitating the automation of the automatic tipping device 100.

[0056] In some examples, both ends of the first fixed shaft 21 are fixed to the second connecting frame 22 through baffles. Specifically, two baffles are provided at both ends of the first fixed shaft 21, and the two baffles at one end of the first fixed shaft 21 are arranged on opposite sides of the first fixed shaft 21 (e.g., Figure 1 The upper and lower sides shown in the figure) are fixedly connected to the second connecting frame 22 by fasteners, and a part of the baffle is inserted into the first fixed shaft 21, which can limit the axial direction of the first fixed shaft 21 and prevent the first fixed shaft 21 from moving along its axial direction, thereby improving the stability of the second hook 12 hooking the second connecting frame 22.

[0057] like Figure 4As shown, in some examples, the rotating mechanism 30 includes a driving device 33, a reduction device 32 and a rotating device 31. The driving device 33 and the reduction device 32 are both located outside the rotating device 31, and the reduction device 32 is connected to the rotating device 31, and the driving device 33 is connected to the reduction device 32. The rotating device 31 has a first turntable 311 and a second turntable 312.

The first turntable 31 is arranged on the outer ring of the second turntable 312, and the first turntable 311 can rotate relative to the second turntable 312, that is, the first turntable 311 rotates along the The first turntable 311 is rotated relative to the second turntable 312 by the outer periphery movement of the second turntable 312, and the driving device 33 can drive the first turntable 311 to rotate relative to the second turntable 312 through the reduction device 32; the driving device 33 can be a driving motor, and the reduction device 32 can be a planetary reducer. The planetary reducer can convert the high-speed and low-torque input speed of the output shaft of the driving motor into a low-speed and high-torque output speed through the reduction device 32 such as a multi-stage planetary gear transmission mechanism, thereby achieving the deceleration purpose of mechanical transmission. Further, the reduction device 32 can transmit torque through the cooperation between the turbine and the worm to drive the first turntable 311 to rotate relative to the second turntable 312.

[0058] like Figure 3 and Figure 4 As shown, in some examples, the first turntable 311 has a plurality of perforations, which are arranged at intervals around the outer periphery of the first turntable 311, and the upper side surface of the first connecting frame 43 also has a plurality of perforations, and the perforations on the first connecting frame 43 correspond to the positions of the perforations on the first turntable 311, so that the first turntable 311 can be fixedly connected to the first connecting frame 43 by fasteners; the second turntable 312 has a plurality of perforations, which are arranged at intervals around the outer periphery of the second turntable 312, and the lower side surface of the second connecting frame 22 also has a plurality of perforations, and the perforations on the second connecting frame 22 correspond to the positions of the perforations on the second turntable 312, so that the second turntable 312 can be fixedly connected to the second connecting frame 22 by fasteners, so that the driving device 33 can drive the first turntable 311 to rotate relative to the second turntable 312, so that the hook mechanism 40 and the second connecting frame 22 can rotate relative to each other.

[0059] like Figure 5 As shown, in some examples, the hook 41 is fixed to one end of the hanging rod 42 (such as Figure 5 The lower end shown in FIG), a plurality of second fixed shafts 44 are arranged along the extension direction of the hanging rod 42 (as shown in FIG. Figure 5The hooks 41 are arranged at intervals in the up-down direction as shown, which can improve the fixing effect of the hooks 41, prevent the hooks 41 from swinging relative to the hanging rods 42, and improve the stability of the hooking side lifting shaft 62 of the hooks 41. Specifically, the number of the second fixing shafts 44 for connecting the hooks 41 and the hanging rods 42 can be two, which can ensure the fixing effect of the hooks 41 and the hanging rods 42 while reducing the cost.

[0060] In some examples, the two ends of the second fixing shaft 44 are fixed to the lower end of the hanging rod 42 through the baffle plates. Specifically, two baffle plates are arranged at each end of the second fixing shaft 44, and the two baffle plates arranged at one end of the second fixing shaft 44 are arranged on the opposite sides of the second fixing shaft 44 (for example, on the left and right sides of the second fixing shaft 44 as shown in the up-down direction) and are fixedly connected to the hanging rod 42 through fasteners, and a part of the baffle plates is inserted into the second fixing shaft 44, which can limit the axial movement of the second fixing shaft 44 and improve the stability of the connection between the hooks 41 and the hanging rods 42. Figure 1

[0061] As shown in Figure 1 In some examples, the hanging rod 42 is further provided with a counterweight 421, which is arranged opposite to the hooks 41. For example, as shown in Figure 1 The counterweight 421 is arranged on the right side of the hooks 41, which can balance the gravity center of the hooks 41 and ensure that the hanging rod 42 always extends along the vertical direction (for example, the up-down direction as shown) without external force, thereby improving the stability of the automatic tilting device 100. Figure 1

[0062] In some examples, the upper end of each of the first hook 11 and the second hook 12 is provided with a winding drum, and a steel wire rope can be wound on the winding drum. The steel wire rope is connected to the first hook 11 or the second hook 12, so that the rotation of the winding drum can realize the lifting of the first hook 11 and the second hook 12. A height gauge is arranged in each winding drum, which can rotate with the winding drum to count the real-time position and feed back the state. That is, the lifting height of the corresponding hook is determined by judging the length change of the part of the steel wire rope outside the winding drum, and then the electric control equipment can calculate the relative height difference between the two hooks according to the lifting heights of the two hooks, and make a judgment, so that the hooks 41 rotate at a suitable height to hook the side lifting shaft or avoid the ladle, which is conducive to the automation of the automatic tilting device 100.

[0063] As shown in Figure 8 ​​As shown, in some specific examples, after the first hook 11 hooks the main lifting shaft 61 of the ladle, the ladle is lifted, at this time, the rotating mechanism 30 drives the hook mechanism 40 to rotate to the second rotating position, so that the guide plate 51 and the guide groove 52 are misaligned, that is, the hook 41 avoids the outer edge of the ladle, after the height difference between the guide plate 51 and the guide groove 52 is reduced to an appropriate distance, then the second hook 12 can continue to lower the height of the hook mechanism 40, until the hook 41 is lower than the side lifting shaft 62 of the ladle, at this time, as shown in Figure 8 b, the rotating mechanism 30 can drive the hook mechanism 40 to rotate to the first rotating position, so that the guide plate 51 and the guide groove 52 are opposite to each other, as shown in Figure 8 c, the second hook 12 can be lifted to lift the hook mechanism 40, so that the guide plate 51 and the guide groove 52 are inserted and matched, the second hook 12 continues to lift the hook mechanism 40, until the hook 41 hooks the side lifting shaft 62 of the ladle, at this time, the guide plate 51 is separated from the lower side of the guide groove 52, as shown in Figure 8 e, the second hook 12 continues to rise, the hanging rod 42 swings to the right side, that is, the ladle can be tilted over.

[0064] After the ladle is tilted over, the second hook 12 can be lowered to lower the hook mechanism 40, until the ladle is in a horizontal state, the second hook 12 can continue to be lowered and lower the hook mechanism 40, so that the guide plate 51 and the guide groove 52 are inserted and matched, and so that the hook 41 starts to separate from the side lifting shaft 62 of the ladle, after the hook 41 and the side lifting shaft 62 are completely separated, the rotating mechanism 30 can drive the hook mechanism 40 to rotate to the second rotating position, at this time, the guide plate 51 and the guide groove 52 are misaligned, that is, the hook 41 avoids the outer edge of the ladle, at this time, the first hook 11 can be lowered to lower the ladle, so that the first hook 11 and the main lifting shaft 61 of the ladle are separated, which is beneficial to the subsequent operation of the automatic tilting device 100.

[0065] According to the crane of the embodiment of the present application, the automatic tilting device 100 is arranged, the hook 41 can accurately hook the side lifting shaft 62 of the ladle, and the hook 41 can rotate during lifting to avoid the outer edge of the ladle, so that the crane is automated, the operation risk is reduced, the safety of the workers is ensured, and the work efficiency is improved.
