DETAILED DESCRIPTION

[0028] In order to better explain the present application, in order to facilitate understanding, the following specific embodiments, combined with the drawings, the technical solutions in the embodiments of the present application are described in detail.

[0029] The technical solutions in the embodiments of the present application will be described in detail below, combined with the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all. As long as the effect of the present application can be played, various changes can be made to the implementation scheme.

[0030] By the personnel in the art, the parts in the case are connected in turn, the specific connection and operation sequence should be referred to the working principle described below, the detailed connection means is the technology known in the art, the working principle and process are mainly introduced below.

[0031] The present embodiment discloses a conveying device for slag treatment, as shown in the figure, the conveying device is mainly used for conveniently hooking and hoisting the slag ladle 4 by the crane 1 and tilting the slag ladle 4. Figures 1 to 9

[0032] ​The main crane 1 moves on the track and the slag ladle 4 to be processed for loading the slag. The crane 1 is provided with the main hook assembly 3 connected to the first hoisting chain and the auxiliary hook 2 connected to the second hoisting chain. The slag ladle 4 is provided with a pair of trunnions 5 and the lifting lug 6 at the outer edge of the slag ladle 4 and at the central position between the two trunnions 5. The trunnions 5 are arranged at the opposite positions of the front and rear ends of the slag ladle 4, and the lifting lug 6 is arranged at the left or right position of the slag ladle 4. In actual use, the main hook assembly 3 is lowered by the first hoisting chain, so that the main hook assembly 3 is hooked on the trunnions 5. The auxiliary hook 2 is lowered by the second hoisting chain, so that the auxiliary hook 2 is hooked on the lifting lug 6. The first hoisting chain and the second hoisting chain are synchronously raised, so that the slag ladle 4 is stably raised. The crane 1 moves to the slag pouring area. At this time, the second hoisting chain is raised again, so that the slag ladle 4 is poured to the other side with the trunnions 5 as the center. With the continuous rising of the second hoisting chain, the slag in the slag ladle 4 is completely poured out. Then, the second hoisting chain is reset, so that the slag ladle 4 is reset. The crane 1 is reset. The first hoisting chain and the second hoisting chain are synchronously lowered, so that the slag ladle 4 is placed at the original position.

[0033] The double-point synchronous lifting ensures the level of the slag ladle 4 in the lifting process, avoids the inclination or shaking caused by the single-point lifting, greatly improves the safety and stability of the lifting operation, and forms the whole process of “lifting-transporting-pouring-resetting-placing” into the autonomous operation without personnel intervention. The operation is simple, and the automation level and operation efficiency of the slag processing are significantly improved.

[0034] Further, on the basis of the above, the main hook assembly 3 comprises the lifting plate 31 connected to the first hoisting chain. The first side plate 32 and the second side plate 33 are hingedly arranged at the opposite positions below the lifting plate 31. The J-shaped hook plate 34 is connected to the side of the bottom of the first side plate 32 opposite to the second side plate 33. The hook plate 34 and the first side plate 32 form the hook cavity 35. When the slag ladle 4 is lifted, the trunnions 5 are located in the hook cavity 35. When the main hook assembly 3 is pulled, the trunnions 5 are clamped at the bending position of the J-shaped hook plate 34. The hook cavity 35 formed by the first side plate 32 and the J-shaped hook plate 34 is mainly used for receiving and hooking the trunnions. The J-shaped structure is simple and reliable, can provide strong locking force, ensures that the connection between the main hook and the trunnions 5 is absolutely stable when the slag ladle 4 weighing several tons is lifted, and will not slip accidentally.

[0035] Further, the third side plate 37 is connected to the side of the second side plate 33 opposite to the first side plate 32 through the connecting plate 311. The disengaging clamping cavity 310 penetrating up and down is formed between the second side plate 33 and the third side plate 37. The entrance clamping cavity 38 is formed between the third side plate 37 and the hook plate 34. One end of the buckle plate 39 is hingedly arranged at the top of the third side plate 37. The other end of the buckle plate 39 is overlapped on the hook plate 34.

[0036] When the buckle plate 39 is overlapped on the hook plate 34 in the buckled state, the entrance clamping cavity 38 is closed, and the hook cavity 35 is communicated with the disengaging clamping cavity 310; when the buckle plate 39 is separated from the hook plate 34 in the opened state, the disengaging clamping cavity 310 is closed, and the hook cavity 35 is communicated with the entrance clamping cavity 38.

[0037] In the embodiment, as shown in the drawings, Figure 2 and Figure 4 the inner wall top of the first side plate 32 is provided with a guide plate 312, when the buckle plate 39 is overlapped on the hook plate 34 in the buckled state, a transverse clamping cavity 318 is formed between the buckle plate 39 above and the guide plate 312, and the transverse clamping cavity 318 is communicated with the hook cavity 35 and the disengaging clamping cavity 310; the transverse clamping cavity 318 is used for the trunnion 5 to smoothly enter the disengaging clamping cavity 310 after being separated from the hook cavity 35.

[0038] The main hook assembly 3 can realize automatic hooking and automatic unhooking through the cooperation of the third side plate 37, the buckle plate 39 and the guide plate 312; the second side plate 33 extends out of the third side plate 37 through the connecting plate 311, and forms the entrance clamping cavity 38 for the trunnion 5 to enter between the hook plate 34; the top of the third side plate 37 is hinged with the buckle plate 39, which can be overlapped on the hook plate 34 to form a movable latch.

[0039] When the buckle plate 39 is overlapped on the hook plate 34, the entrance clamping cavity 38 is closed to prevent the trunnion 5 from accidentally sliding out; at the same time, the buckle plate 39 and the guide plate 312 on the top of the first side plate 32 form a transverse clamping cavity 318, which is communicated with the hook cavity 35 and the disengaging clamping cavity 310; in this state, the trunnion 5 is safely limited in the hook cavity 35.

[0040] When the main hook assembly 3 is lowered to the ladle 4, the trunnion 5 will push the buckle plate 39 to turn over from the entrance clamping cavity 38; at this time, the buckle plate 39 closes the entrance of the disengaging clamping cavity 310, forcing the trunnion 5 to enter the hook cavity 35 along the guide of the guide plate 312; when unhooking is needed, the main hook assembly 3 is lowered again, and the trunnion 5 leaves the hook cavity 35 under the action of gravity, enters the transverse clamping cavity 318, and finally completely separates from the main hook assembly 3 through the disengaging clamping cavity 310.

[0041] By adopting the above technical scheme, the whole process does not need manual intervention, and only relies on the lifting of the main hook assembly 3 to complete the "hooking" and "unhooking", realizing automatic operation, which not only greatly improves the operation efficiency, but also avoids the danger of manual unhooking by workers in high temperature and high risk environment.

[0042] One end of the guide plate 312 is fixed with the first side plate 32 to form a fixed end, and the other end extends towards the second side plate 33 to form an abutting end 317 which abuts against the second side plate 33; in actual use, when the abutting end 317 abuts against the second side plate 33, the relative distance between the first side plate 32 and the second side plate 33 is formed, that is, the distance between the third side plate 37 and the hook plate 34 to form the entrance gap 38.

[0043] The lower edge of the guide plate 312 close to the side of the abutting end 317 forms a limiting edge 316 which abuts against the buckle plate 39 when the buckle plate 39 is turned to the open state; the lower edge of the guide plate 312 close to the side of the fixed end forms a guide edge 315 which is smoothly connected with the first side plate 32.

[0044] In one working mode, when the main hook assembly 3 is linearly lowered, the trunnion 5 enters through the entrance gap 38, and as the main hook assembly 3 continues to descend, the trunnion 5 pushes open the buckle plate 39 to turn the buckle plate 39; at this time, the buckle plate 39 is closed and separated from the clamping gap 310, and the trunnion 5 enters the hook cavity 35 along the guide edge 315 of the lower edge of the guide plate 312 in the transverse clamping gap 318, and is pulled up when the main hook assembly 3 is pulled up; after the ladle 4 is lowered, the main hook assembly 3 continues to descend, at this time, the trunnion 5 enters the transverse clamping gap 318 along the guide edge 315, and finally separates from the main hook assembly 3 through the separation gap 310.

[0045] In this embodiment, the top of the buckle plate 39 is provided with an upper buckle plate 313, one end of the upper buckle plate 313 is hinged with the end of the hook plate 34 overlapped with the buckle plate 39, and the other end is buckled on the buckle plate 39, and the end of the upper buckle plate 313 buckled on the buckle plate 39 forms a notch groove 314; the lower part of the upper buckle plate 313 is connected with the buckle plate 39 through a spring 319; by using the design of the upper buckle plate 313, when the trunnion 5 enters the separation gap 310 through the transverse clamping gap 318, the circumferential wall surface of the trunnion 5 is pressed on the upper buckle plate 313, so that the upper buckle plate 313 is attached to the buckle plate 39, at this time, the width distance of the transverse clamping gap 318 is increased, so that the trunnion 5 is more convenient to move to the separation gap 310.

[0046] The outer side of the first side plate 32 is provided with a counterweight plate 36; by the design of the counterweight plate 36, when the main hook assembly 3 is not hooked with the trunnion 5, the weight at the first side plate 32 is greater than that at the second side plate 33, so that the whole main hook assembly 3 is in an inclined state, and the transverse clamping gap 318 is also in an inclined state, so that the trunnion 5 is in a slight inclined state when it moves from the hook cavity 35 to the transverse clamping gap 318 and then to the separation gap 310, which is more convenient for the trunnion 5 to separate.

[0047] In addition, the trunnion 5 in this embodiment is like Figure 9As shown, the trunnion 5 includes a fixed shaft seat with the ladle 4, the shaft seat is provided with an insertion cavity 13, the shaft rod 14 is inserted into the insertion cavity 13, the shaft rod 14 is clamped on the shaft seat through the sleeve 15, the part of the shaft rod 14 extending out of the sleeve 15 is formed with an end rod part, the diameter of the end rod part is smaller than the entrance clamping cavity 38, the hook cavity 35 and the disengaging clamping cavity 310; in the implementation, the end rod part moves in the entrance clamping cavity 38, the hook cavity 35 and the disengaging clamping cavity 310; the hooking part of the trunnion 5 forms a replaceable shaft rod 14, so that the trunnions 5 on different models of the ladles 4 can be provided with the same diameter of the shaft rod 14, and the main hook assembly 3 can hook each of the ladles 4, thereby increasing the versatility.

[0048] The outer side of the shaft rod 14 is wrapped with a protective clamp sleeve 17 which can surround a whole circle, one end of the protective clamp sleeve 17 extends into the insertion cavity, the other end extends out of the sleeve 15, the inner side of the front end of the sleeve 15 is formed with an outer wrapping part 16 which can abut against the protective clamp sleeve 17; the protective clamp sleeve 17 is designed to enhance the strength of the shaft rod 14, and the outer wrapping part 16 is used to enhance the clamping and fixing effect of the protective clamp sleeve 17.

[0049] In the embodiment, the lower part of the lifting lug 6 is provided with the protruding hook 7, when the lifting lug 6 naturally swings downward, the protruding hook 7 can abut against the outer wall surface of the ladle 4, so that the opening of the lifting lug 6 faces downward, when the auxiliary hook 2 is below the lifting lug 6 and moves upward, the auxiliary hook 2 can directly enter the opening of the lifting lug 6 to lift the lifting lug 6, thereby preventing the opening of the conventional lifting lug 6 from facing the ladle 4 in the normal state, so that the auxiliary hook 2 cannot be hooked by itself.

[0050] In addition, in order to limit the swing angle of the lifting lug 6 lifted by the auxiliary hook 2, the embodiment is provided with Figure 8 As shown, the upper part of the lifting lug 6 is provided with the limiting plate 8, the limiting plate 8 is in the form of a cam, including the shaft center part 11 which is rotationally connected with the ladle 4 and the limiting part 9 which is located at the other end of the shaft center part 11 and abuts against the lifting lug 6; a plurality of positioning screw holes 12 are equidistantly distributed on the outer wall surface of the ladle 4 with the center of the shaft center part 11 as the center, and the limiting plate 8 can be connected in any positioning screw hole 12 through the positioning bolt 10, so that the limiting plate 8 can be positioned on the predetermined swing track; the swing angle of the limiting plate 8 is changed by fixing the positioning bolt 10 in different positioning screw holes 12, and then the outer wall surface of the lifting lug 6 at different positions is in contact with the limiting part 9 of the limiting plate 8, so that the maximum upward swing angle of the lifting lug 6 is adjustable, and when the auxiliary hook 2 lifts the lifting lug 6, the inclination angle of the ladle 4 can be adjusted through the same lifting height, so that the discharge amount is controllable.

[0051] In addition, the embodiment also discloses a detailed working principle, and the specific content is as follows:

[0052] Firstly, the crane 1 moves to the position directly above the full slag ladle 4; firstly, the first hoisting chain is released, and the main hook assembly 3 is lowered; the trunnion 5 pushes the buckle plate 39 and automatically slides into the hook cavity 35 along the guide edge 315, and then the main hook assembly 3 is lifted, and the buckle plate 39 is reset and buckled under the shaking vibration force; then, the second hoisting chain is released, and the auxiliary hook 2 is aligned with the lifting lug 6 which is opened downward due to the effect of the protruding hook 7, and the auxiliary hook 2 is directly lifted to complete the hook connection;

[0053] The first and second hoisting chains are synchronously lifted to stably vertically lift the slag ladle 4 off the ground; then, the crane 1 carries the slag ladle 4 to the designated slag pouring area along the track;

[0054] In the pouring area, the first hoisting chain keeps the height unchanged, and the second hoisting chain is independently and continuously lifted; the auxiliary hook 2 pulls the lifting lug 6 to make the slag ladle 4 tilt to one side around the trunnion 5 locked by the main hook assembly 3; after the pouring is completed, the second hoisting chain is lowered, and the slag ladle 4 is reset to the horizontal state under the action of gravity; the crane 1 returns to the initial position with the empty slag ladle 4; the first and second hoisting chains are synchronously lowered to stably put the empty slag ladle 4 back to the ground;

[0055] After the slag ladle 4 is put on the ground, the first hoisting chain of the main hook assembly 3 continues to be lowered; the trunnion 5 is separated from the hook cavity 35 under the action of gravity, enters the transverse clamping cavity 318 along the guide edge 315, and presses the upper buckle plate 313 to increase the passing space, and finally smoothly passes through the separation clamping cavity 310 to completely separate from the bottom of the main hook assembly 3; the auxiliary hook 2 is also lowered to separate from the lifting lug 6; thus, a complete working cycle is completed, and the device is ready for the next operation.
