[0059] The first lifting mechanism 2 is arranged on the travelling trolley 1, and is used for driving the lifting appliance 4 to move up and down along a vertical direction;

[0060] The second lifting mechanism 7 is used for driving the rail car assembly 6 to move back and forth along the second direction, driving the third traction rope 61 and the fourth traction rope 62 to pull the rotating disc 42 to rotate, and then driving the lifting hook 44 to be hooked and the swing arm beam 43 to be turned over, or driving the lifting hook 44 to be unhooked and the swing arm beam 43 to be reset; wherein the first direction is the front-rear direction in the Figure 1 , and the second direction is the left-right direction in the Figure 1 ;

[0061] As shown in Figures 1-10 , the utility model discloses a travelling trolley 1, lifting appliance 4, rail car assembly 6, first lifting mechanism 2 and second lifting mechanism 7, through first lifting mechanism 2, lower lifting appliance 4, use the lifting hook 44 to carry out hooking, after the travelling trolley 1 drives the whole device to move on the portal frame, move the ladle 9 to the slag pouring area, then carry out the operation of turning over through second lifting mechanism 7, compared with the existing hook body and rope easy to swing and inconvenient to position unhooking, when using the device, only need to adjust the position of lifting appliance 4, make the ladle 9 be located between the two side frames 41, drive the lifting hook 44 to realize hooking and unhooking, and the positioning is more accurate, and the positioning speed is faster and more convenient.

[0062] In some embodiments, as Figure 3As shown, the third rope fixing part 48 is arranged above the swing arm beam 43 corresponding to the rotating disc 42, and is used for fixing the bottom end of the fourth traction rope 62. The second rope fixing part 47 is arranged below the swing arm beam 43 corresponding to the rotating disc 42, and is used for fixing the bottom end of the third traction rope 61. The two end faces of the rotating disc 42 are both provided with annular baffles 49, which limit the third traction rope 61 and the fourth traction rope 62, so as to ensure that the third traction rope 61 can stably pull the rotating disc 42 to rotate counterclockwise, and the fourth traction rope 62 can stably drive the rotating disc 42 to rotate clockwise.

[0063] In some embodiments, the swing arm beam 43 is provided with a swing arc-shaped plate 46 at the end close to each other, and the two hooks 44 are both provided with a swing guide wheel 45 at the end away from each other. The axis of each swing guide wheel 45 extends in the first direction, and the lower edge of the swing guide wheel 45 is rollably connected with the top surface of the swing arc-shaped plate 46.

[0064] As shown in Figure 2 and Figure 3 , before the swing arm beam 43 flips the ladle 9, the upper edge of the swing arc-shaped plate 46 is in contact with the top end of the swing guide wheel 45. The second lifting mechanism 7 drives the hook 44 to move to the hanging shaft 91 of the ladle 9, and the hook 44 and the hanging shaft 91 are separated after the hook 44 moves to the bottom end of the hanging shaft 91. After the lifting appliance 4 is pulled upward, the hook 44 can lift the ladle 9. The swing arm beam 43 continues to swing to realize the flipping of the ladle 9. During the resetting of the swing arm beam 43, the top end of the swing arc-shaped plate 46 is in contact with the upper edge of the swing guide wheel 45, which pushes the hook 44 to move away from the hanging shaft 91 to realize unhooking. By using this structure, the hooking can be realized after the flipping of the ladle 9, and the unhooking can be realized after the resetting, which improves the hooking efficiency and is simple to operate. Only two operations are needed, and it is not easy to make mistakes, which improves the unhooking efficiency.

[0065] In some embodiments, the top end of each side frame 41 is provided with a connecting assembly 3. The connecting assembly 3 includes a rectangular frame 31 arranged at the top end of the side frame 41. The top end of the rectangular frame 31 is uniformly provided with a plurality of first movable pulleys 32.

[0066] The first lifting mechanism 2 includes a first winding drum 22 arranged on the walking trolley 1. A plurality of lifting traction ropes are wound on the first winding drum 22. The number of the first movable pulleys 32 is consistent with the number of the lifting traction ropes, and each lifting traction rope is correspondingly arranged on the bottom end of the corresponding first movable pulley 32.

[0067] As shown in Figure 2 , Figure 7 and Figure 8As shown, the walking trolley 1 top end is provided with a plurality of first rope fixing members 24 for fixing each lifting traction rope. Optionally, four first movable pulleys 32 are arranged at the four corners of the rectangular frame 31 to ensure stable lifting. Two first traction ropes 23 and two second traction ropes 26 are wound on the first winding drum 22. In order to ensure that each lifting traction rope is vertically dropped, the two first traction ropes 23 are directly dropped and then pass through the two first movable pulleys 32 and are connected with the first rope fixing members 24. The walking trolley 1 is also provided with two first steering guide wheels 27. The two second traction ropes 26 first pass through the first steering guide wheels 27 in the horizontal direction, then pass through the two first movable pulleys 32 and are connected with the first rope fixing members 24.

[0068] In some embodiments, the first lifting mechanism 2 further comprises a labor-saving pulley assembly. The labor-saving pulley assembly comprises a plurality of first fixed pulleys 25 arranged at the bottom end of the walking trolley 1. Each lifting traction rope passes through the bottom end of the corresponding first movable pulley 32, passes through the top end of the first fixed pulley 25 and the bottom end of the first movable pulley 32 several times, and is then connected with the bottom end of the walking trolley 1.

[0069] In some embodiments, the track car body comprises a small car frame 63 shaped as >. The small car frame 63 is provided with four-rope pulleys 65 at the middle part, and three-rope pulleys 64 at the top end and the bottom end. The two side frames 41 are provided with first guide wheels 410 at the end close to the three-rope pulleys 64 in the second direction, and are provided with second guide wheels 411 at the end close to the four-rope pulleys 65 in the second direction. The top of the third traction rope 61 of the two track car assemblies 6 passes through the corresponding first guide wheels 410 and the three-rope pulleys 64. The top of the fourth traction rope 62 of the two track car assemblies 6 passes through the corresponding second guide wheels 411 and the two four-rope pulleys 65. The top of the third traction rope 61 and the fourth traction rope 62 moves synchronously with the rectangular frame 31.

[0070] As shown in Figure 2 , Figure 3 and Figure 4 , optionally, the top of the third traction rope 61 and the fourth traction rope 62 is fixedly connected with the rectangular frame 31. The third traction rope 61 passes through the left side and the top surface of the three-rope pulley 64, and is then fixedly connected with the rectangular frame 31. When the track car body moves to the left, the three-rope pulley 64 drives the third traction rope 61 to move to the left, thereby driving the bottom end of the third traction rope 61 to rotate the rotating disc 42 counterclockwise. Similarly, the fourth traction rope 62 passes through the right side and the top surface of the four-rope pulley 65 above, and is then fixedly connected with the rectangular frame 31. This is one of the optional schemes for synchronous movement.

[0071] In some embodiments, a guide pulley component 5 is provided on the rectangular frame 31. The guide pulley component 5 includes two limiting frames 51 disposed at the top of the rectangular frame 31 along a first direction. The limiting frame 51 includes a plurality of steel pipes extending in a second direction and end plate frames disposed at both ends of each steel pipe. The main body of the railcar is disposed within the limiting frame 51, and each steel pipe restricts the main body of the railcar from swaying along the first direction.

[0072] like Figures 2-5 As shown, the front and rear ends of the top of the small trolley frame 63 are restricted by two steel pipes, and the front and rear ends of the bottom are also restricted by two steel pipes, thus ensuring that the small trolley frame 63 will not sway back and forth.

[0073] In some embodiments, both ends of the two limiting frames 51 are provided with connecting sheet metal parts 53, and a connecting rod 52 is provided between the connecting sheet metal parts 53 on the same side along the second direction; such as Figures 2-5 As shown, the combination of connecting rod 52 and connecting sheet metal parts 53 connects the limiting frame 51, achieving rectangular installation and improving overall stability. Furthermore, for the synchronous movement of the tops of the third traction rope 61 and the fourth traction rope 62 with the rectangular frame 31, preferably, each of the four connecting sheet metal parts 53 is provided with a guide wheel 54 in the middle. A first linkage rope 610 is provided between the tops of the two third traction ropes 61, and the first linkage rope 610 is wound around the rope grooves of the two guide wheels 54 on the same side. A second linkage rope 611 is provided between the tops of the two fourth traction ropes 62, and the second linkage rope 611 is wound around the rope grooves of the two guide wheels 54 on the other side. Because the guide pulley component 5 is installed on the rectangular frame 31, and both the first linkage rope 610 and the second linkage rope 611 are installed between the guide wheels 54, the purpose of connecting the third traction rope 61 and the fourth traction rope 62 with the rectangular frame 31 is achieved, realizing synchronous movement. This scheme combines the two third traction ropes 61 into a single rope body through the first linkage rope 610, resulting in more even force distribution and better performance during pulling.

[0074] In some embodiments, the second lifting mechanism 7 further includes a second drum 79, on which two rope groups are wound at both ends along the first direction. The two railcar assemblies 6 correspond to the two rope groups respectively. Each rope group includes a fifth traction rope 71 and a sixth traction rope 76 which is wound in the opposite direction to the fifth traction rope 71.

[0075] One end of the main body of the railcar along the second direction is connected to the fifth traction rope 71, and the other end is connected to the sixth traction rope 76;

[0076] like Figure 9 and Figure 10As shown, when the second winding drum 79 rotates counterclockwise, the fifth traction rope 71 will be retracted, thereby pulling the railcar assembly 6 to move to the right. At this time, because the winding direction of the sixth traction rope 76 is opposite to that of the fifth traction rope 71, the sixth traction rope 76 will be simultaneously released, and will not interfere with the operation of the railcar assembly 6. Similarly, when the second winding drum 79 rotates clockwise, the sixth traction rope 76 will be retracted, thereby pulling the railcar assembly 6 to move to the left, and the fifth traction rope 71 will be simultaneously released, thereby achieving the purpose of the left and right reciprocating movement of the railcar assembly 6.

[0077] In some embodiments, the second winding drum 79 is arranged on the walking trolley 1, and the second lifting mechanism 7 further comprises two sets of labor-saving pulley assemblies. One set of labor-saving pulley assembly comprises a second fixed pulley 72 arranged at the bottom end of the walking trolley 1 and a second movable pulley 73 arranged on the end plate frame. The other set of labor-saving pulley assembly comprises a third fixed pulley 77 arranged at the bottom end of the walking trolley 1 and a third movable pulley 78 arranged at the top end of the rectangular frame 31.

[0078] The sixth traction rope 76 is wound around the bottom surface of the third movable pulley 78 and the top surface of the third fixed pulley 77 for several turns, and then is connected to the first winding drum 22 through the railcar body. The fifth traction rope 71 passes through the railcar body, is wound around the bottom surface of the second movable pulley 73 and the top surface of the second fixed pulley 72 for several turns, and is then connected to the first winding drum 22.

[0079] The number of turns of the fifth traction rope 71 and the sixth traction rope 76 is consistent with the number of turns of the lifting traction rope around the top end of the first fixed pulley 25 and the bottom end of the first movable pulley 32, and the nominal diameters of the corresponding winding drums are consistent. That is, the nominal diameters of the first winding drum 22 and the second winding drum 79 are consistent.

[0080] As shown in FIGS. 1-3, Figure 4 , Figure 9 and Figure 10 Because the second winding drum 79 is arranged on the walking trolley 1, if the fifth traction rope 71 and the sixth traction rope 76 are fixed on the walking trolley 1 or the rectangular frame 31, the fifth traction rope 71 and the sixth traction rope 76 cannot move synchronously when the first winding drum 22 releases the lifting traction rope, which will interfere with the lifting of the rectangular frame 31. Therefore, the third fixed pulley 77 and the third movable pulley 78 are arranged, and the number of turns of the third fixed pulley 77 and the third movable pulley 78 is consistent with that of the labor-saving pulley assembly, that is, the winding ratios are the same, and the nominal diameters of the corresponding winding drums are consistent. At this time, when the first winding drum 22 releases the lifting traction rope, the second winding drum 79 remains stationary. At this time, the first winding drum 22 will also release the fifth traction rope 71 and the sixth traction rope 76 synchronously. At this time, the lengths of the ropes released are consistent, and there will be no interference. After the lifting is completed, the second winding drum 79 is rotated, and the other end of the fifth traction rope 71 and the sixth traction rope 76 remains stationary, so that the fifth traction rope 71 and the sixth traction rope 76 are retracted on one side and extended on the other side, thereby achieving the purpose of pulling the railcar assembly 6.

[0082] As shown in Figure 4 , Figure 9 and Figure 10 , if the sixth traction rope 76 passes through the railcar body means that the sixth traction rope 76 directly passes around the six-rope pulley 67 once, the transmission resistance is larger, which is not conducive to pulling the railcar assembly 6 to move, therefore, the fixed wheel 74 is arranged to make the sixth traction rope 76 pass around the six-rope pulley 67 and the fixed wheel 74 several times, which achieves the purpose of simulating a movable pulley set and realizes the effect of saving effort, which is more convenient for the sixth traction rope 76 to pull the railcar assembly 6 more smoothly, and the guide wheel set 75 is arranged, which is alternatively a winding wheel, the fifth traction rope 71 passes around the five-rope pulley 66 and the winding wheel several times, which achieves the purpose of simulating a movable pulley set and realizes the effect of saving effort, and further preferably, the five-rope pulley 66 is arranged with two, which are respectively located at the front end and the rear end of the small trolley frame 63, and the guide wheel set 75 comprises a first guide wheel 751, a second guide wheel 752, a third guide wheel 753, a fourth guide wheel 754, a fifth guide wheel 755, a sixth guide wheel 756 and a seventh guide wheel 757, referring to Figure 4 , the fifth traction rope 71 after being released from the first winding drum 22, first passes through the seventh guide wheel 757 and the five-rope pulley 66 from left to right, and passes through the sixth guide wheel 756 again, then passes around the five-rope pulley 66 again, then passes the fifth guide wheel 755 to guide the fifth traction rope 71 to the back end of the small trolley frame 63, then passes around the five-rope pulley 66 at the back end, then passes towards the fourth guide wheel 754, then passes from the top of the fourth guide wheel 754 back to the bottom of the five-rope pulley 66 at the back end, then passes out from the bottom of the five-rope pulley 66 to the third guide wheel 753, then passes from the third guide wheel 753 to the second guide wheel 752, then passes from the second guide wheel 752 back to the first guide wheel 751, which is a kind of effort-saving pulley set, and also plays a role in saving effort, improving the smoothness and stability of pulling, in addition, the guide wheel set 75 can also be other effort-saving pulley sets, which mainly plays a role in saving effort.
