[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 lower side shown in FIG), and 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 FIG). 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. The hook 41 is fixed to the lower end of the hanging rod 42 (such as 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 of ensuring that the guide plate 51 can be plugged into and fitted in the guide groove 52 , the guide plate 51 can also be provided on the hook mechanism 40 , and the guide groove 52 can be provided on the first hook 11 .

[0046] like Figure 2 As shown, in some examples, the upper side of the guide slot 52 (eg Figure 2 The upper side shown in FIG. 1 is further provided with a first guide groove 521, which is arranged along a direction close to the guide groove 52 (as shown in FIG. Figure 2 The cross-sectional size (as shown in the direction from top to bottom) gradually decreases, that is, the opening of the first guide groove 521 faces upward and tends to shrink downward, 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, which can improve the accuracy of the hook 41 hooking the side hanging shaft 62, and reduce the influence of processing and assembly accuracy on the device, which is conducive to reducing costs.

[0047] like Figure 2 As shown, in some examples, the lower side of the guide slot 52 (eg Figure 2 The lower side shown in FIG. 1 is further provided with a second guide groove 522, which is arranged along a direction close to the guide groove 52 (as shown in FIG. Figure 2 The cross-sectional size in the direction from bottom to top) gradually decreases, that is, the opening of the second guide groove 522 faces downward and tends to shrink upward, 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, thereby improving the accuracy of the hook 41 hooking the side hanging shaft 62, and reducing the influence of processing and assembly accuracy on the device, which is conducive to reducing costs.

[0048] In some examples, the guide plate 51 is provided on the first hook 11, and the guide plate 51 includes two oppositely arranged ones, such as Figure 1 As shown, under the premise of ensuring that the guide groove 52 opens toward 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 to the right side of the first hook 11, so as to facilitate the assembly of the automatic tipping device 100 and the change of the tipping direction of the slag bag. At the same time, it can balance the center of gravity of the first hook 11, thereby improving the stability of the main suspension shaft 61 for the first hook 11 to hook the slag bag, preventing the first hook 11 from being separated from the main suspension shaft 61, and improving the reliability and safety of the device.

[0049] In some examples, the guide groove 52 is provided on the outside of the hanging rod 42, for example, Figure 1 As shown, the guide groove 52 is provided on the left side of the hanging rod 42, and the extension direction of the guide groove 52 (as shown in FIG. Figure 1 The left and right directions shown in FIG) and the extension direction of the hanging rod 42 (as shown in FIG) Figure 1The guide groove 52 is perpendicular to the guide plate 51 so as to facilitate the plug-in fit between the guide groove 52 and the guide plate 51.

[0050] like Figure 1 、 Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the hook mechanism 40 further includes a first connecting frame 43, the first connecting frame 43 is connected to the rotating mechanism 30, the hanging rod 42 is connected to the first connecting frame 43 through the rotating shaft 431, and the first connecting frame 43 is provided at one end of the hanging rod 42 away from the hook 41 (as shown in FIG. Figure 5 The upper end of the hanging rod 42 is shown in the figure), and the rotating shaft 431 passes through the opposite sides of the upper end of the hanging rod 42 and the opposite sides of the first connecting frame 43, so that the hanging rod 42 is rotatably connected to the first connecting frame 43 through the rotating shaft 431, so that the hanging rod 42 can swing relative to the first connecting frame 43.

[0051] The extending direction of the rotating shaft 431 is perpendicular to the extending direction of the hanging rod 42 (eg Figure 1 As shown in the up and down direction), after the hook mechanism 40 is rotated to the first rotation position, and when the hook 41 hooks the side hanging shaft 62 of the slag bag and rises together with the second hook 12, the hanging rod 42 can be moved to the side away from the slag bag (such as Figure 1 The right side of the slag ladle is shown in FIG. 2 , and the second hook 12 is swung to balance the forces in various directions in the automatic tipping device 100, thereby ensuring that the hook 41 is always hooked to the side hanging shaft 62 in the absence of external force, thereby reducing the probability of the hook 41 being separated from the side hanging shaft 62 during the tipping of the slag ladle, and reducing the probability of the second hook 12 being separated from the second connecting frame 22, thereby improving the stability and safety of the automatic tipping device 100.

[0052] In some examples, both ends of the rotating shaft 431 are fixed to the first connecting frame 43 through baffles. Specifically, two baffles are respectively provided at both ends of the rotating shaft 431, and the two baffles at one end of the rotating shaft 431 are arranged on opposite sides of the rotating shaft 431 (e.g., Figure 1 The upper and lower sides shown in the figure) are fixedly connected to the first connecting frame 43 by fasteners, and a part of the baffle is inserted into the rotating shaft 431, which can limit the axial direction of the rotating shaft 431 and prevent the rotating shaft 431 from moving along its axial direction, thereby improving the swing stability of the hanging rod 42.

[0053] like Figure 6 As shown, in some examples, the outer end of the shaft 431 (such as Figure 6 The left and right ends shown in the figure can be provided with multiple bearings 432, the inner ring of the bearing 432 contacts the outer periphery of the rotating shaft 431, and the outer ring of the bearing 432 contacts 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 friction resistance of the rotation of the rotating shaft 431 can be reduced, thereby improving the flexibility of the hanging rod 42 in swinging.

[0054] like Figure 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 connected to the hook mechanism 40, and the second turntable 32 is connected to the connecting mechanism 20. 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 and 42 are arranged at intervals (in the upper and lower directions shown), which can improve the fixing effect of the hook 41, prevent the hook 41 from swinging relative to the hanging rod 42, and improve the stability of the hook 41 hooking the side hanging shaft 62. Specifically, the number of the second fixed shafts 44 for connecting the hook 41 and the hanging rod 42 can be two, which ensures the fixing effect of the hook 41 and the hanging rod 42 while reducing the cost.

[0060] In some examples, both ends of the second fixed shaft 44 are fixed to the lower end of the hanging rod 42 through baffles. Specifically, two baffles are respectively provided at both ends of the second fixed shaft 44, and the two baffles at one end of the second fixed shaft 44 are arranged on opposite sides of the second fixed shaft 44 (such as Figure 1 The upper and lower sides shown in the figure) are fixedly connected to the hanging rod 42 by fasteners, and a part of the baffle is inserted into the second fixed shaft 44, which can limit the axial direction of the second fixed shaft 44 and prevent the axial movement of the second fixed shaft 44, thereby improving the stability of the connection between the hook 41 and the hanging rod 42.

[0061] like Figure 1 As shown, in some examples, a counterweight 421 is further provided on the hanging rod 42, and the counterweight 421 is arranged opposite to the hook 41, for example, Figure 1 As shown, the counterweight 421 is located on the right side of the hook 41, which plays a role in balancing the center of gravity of the hook 41, and can ensure that the hanging rod 42 always moves in the vertical direction (such as Figure 1 The automatic tilting device 100 extends in the up and down directions as shown, thereby improving the stability of the automatic tilting device 100.

[0062] In some examples, a drum is provided at the upper end of the first hook 11 and the second hook 12, on which a wire rope can be wound, and the wire rope is connected to the first hook 11 or the second hook 12, so that the rotation of the drum can realize the lifting and lowering of the first hook 11 and the second hook 12, and a height meter is provided in each drum, which can rotate with the rotation of the drum to perform real-time position counting and feedback status, that is, by judging the change in the length of the wire rope on the outer part of the drum, the lifting height of the corresponding hook can be determined, and then the electronic control equipment can calculate the relative height difference between the two hooks according to the lifting height of the two hooks, and make a judgment, so that the hook 41 rotates at an appropriate height to hook the side shaft or avoid the slag bag, which is conducive to the automation of the automatic tipping device 100.

[0063] like Figure 8As shown, in some specific examples, after the first hook 11 hooks the main hanging shaft 61 of the slag bag, the slag bag is driven to rise. At this time, the rotating mechanism 30 drives the hook mechanism 40 to rotate to the second rotation position, so that the guide plate 51 and the guide groove 52 are staggered, that is, the hook 41 avoids the outer edge of the slag bag. After the height difference between the guide plate 51 and the guide groove 52 is reduced to a suitable distance, the second hook 12 can continue to drive the hook mechanism 40 to descend until the hook 41 is lower than the side hanging shaft 62 of the slag bag. At this time, Figure 8 As shown in b, the rotating mechanism 30 can drive the hook mechanism 40 to rotate to the first rotation position, so that the guide plate 51 and the guide groove 52 are opposite to each other, as shown in FIG. Figure 8 As shown in Figure c, the second hook 12 can rise to drive the hook mechanism 40 to rise, so that the guide plate 51 is plugged into the guide groove 52. The second hook 12 continues to drive the hook mechanism 40 to rise until the hook 41 hooks the side hanging shaft 62 of the slag ladle. At this time, the guide plate 51 is separated from the guide groove 52 from the lower side of the guide groove 52. Figure 8 As shown in FIG. 4 , the second hook 12 continues to rise, and the hanging rod 42 swings to the right, thereby realizing the tipping of the slag bag.

[0064] After the slag bag is tipped over, the second hook 12 can be lowered to drive the hook mechanism 40 to descend until the slag bag is in a horizontal state. The second hook 12 can continue to descend and drive the hook mechanism 40 to descend, so that the guide plate 51 is plugged into the guide groove 52, and the hook 41 begins to disengage from the side suspension shaft 62 of the slag bag. After the hook 41 is completely disengaged from the side suspension shaft 62, the rotating mechanism 30 can drive the hook mechanism 40 to rotate to the second rotation position. At this time, the guide plate 51 and the guide groove 52 are staggered, that is, the hook 41 avoids the outer edge of the slag bag. At this time, the first hook 11 can be lowered to drive the slag bag to descend, so that the first hook 11 is disengaged from the main suspension shaft 61 of the slag bag, which is conducive to the subsequent automated operation of the automatic tipping device 100.

[0065] According to an embodiment of the present invention, the crane includes an automatic tipping device 100. By providing the automatic tipping device 100, the hook 41 can be accurately hooked to the side hanging shaft 62 of the slag bag, and the hook 41 can be rotated during the lifting process to avoid the outer edge of the slag bag, thereby realizing the automation of the crane, reducing operation risks, ensuring the safety of workers, and improving work efficiency.
