[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Please see Figure 1-11 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0034] like Figure 1-4 As shown, a slag discharger lifting device includes a lifting device beam 1 located below the hoisting drum of the slag discharger and a slag hopper 7 for loading and unloading slag. The slag hopper 7 has connecting shafts 71 for lifting on both sides. A hook assembly 3 is installed below the middle of the lifting device beam 1. Hanging plates 5 and easily detachable plate hook assemblies 6 are symmetrically arranged on both sides of the hook assembly 3. The hanging plates 5 are connected to the plate hook assemblies 6, and the plate hook assemblies 6 are connected to the connecting shafts 71 on both sides of the slag hopper 7.

[0035] A connecting component 4 is installed above the hanging plate 5, and the connecting component 4 is connected to the lifting beam 1;

[0036] The upper surface of the lifting beam 1 is symmetrically fixed with lifting pulley blocks 2. The lifting pulley blocks 2 are connected to the hoisting drum of the slag discharge machine. The lifting pulley blocks 2 are lifted by the hoisting drum of the slag discharge machine, which drives the lifting beam 1 to rise. Then, in conjunction with the hook assembly 3 and the plate hook assembly 6, the slag hopper 7 is lifted.

[0037] The aforementioned slag discharger, hook assembly 3, and lifting pulley assembly 2 are all existing technologies and will not be described in detail here.

[0038] like Figure 2-3As shown, in this embodiment, the connecting component 4 includes a connecting frame 41 and a lifting fork 42. Fixing plates 11 are symmetrically installed on both sides of the lifting beam 1 relative to the position of the connecting frame 41. A horizontal sliding groove 111 is opened on the surface of the fixing plate 11. A horizontal sliding groove 122 is opened on the surface of the lifting beam 1 above the sliding groove 111. The connecting frame 41 is arranged above the lifting fork 42 and is fixedly engaged. A lifting fork pin 43 is inserted at the connection position of the connecting frame 41 and the lifting fork 42. The lifting fork pin 43 is slidably arranged in the sliding groove 12. Sliding pins that slide in the sliding groove 111 are symmetrically installed above the connecting frame 41.

[0039] The connecting frame 41 and the lifting fork 42 can slide left and right on the lifting beam 1 by means of the lifting fork pin 43 and the sliding pin, which drives the hanging plate 5 and the plate hook assembly 6 below to move, so as to facilitate connection with the connecting shaft 71 of the slag hopper 7.

[0040] like Figure 2-3 As shown, in this embodiment, a hanging plate pin 44 is installed at the lower end of the hanging fork 42, and a bushing 45 is installed on the circumferential surface of the hanging plate pin 44. The bushing 45 is fixed to the upper end of the hanging plate 5.

[0041] like Figure 4-11 As shown, in this embodiment, the plate hook assembly 6 includes a support block 64 and symmetrically arranged hanging plates 61. The surface of the hanging plate 61 is provided with a connecting groove 62. The connecting groove 62 is divided into an upper through hole 621 and a lower vertical rectangular through groove 621. The diameter of the through hole 621 is larger than the diameter of the connecting shaft 71. The through groove 621 is adapted to the connecting shaft 71. A communicating sliding groove 612 is provided below the connecting groove 62.

[0042] A sliding block 63 is fixedly provided on the lower end face of the support block 64. The support block 64 slides in the through groove 621, and the sliding block 63 slides in the sliding groove 612.

[0043] The upper end face of the support block 64 is arc-shaped and is adapted to the connecting shaft 71. Several grooves 642 are provided on the arc-shaped surface above the support block 64, and several balls 641 are rolled in the grooves 642.

[0044] A cylindrical groove 633 is provided on the lower end face of the sliding block 63, and a return spring 631 is fixedly provided in the cylindrical groove 633. A pad 632 is fixedly provided on the lower end face of the return spring 631.

[0045] Before merging the two hanging plates 61, first install the pad 632, sliding block 63 and support block 64 into the sliding groove 612, and then use bolts to fix the two hanging plates 61.

[0046] Specifically, after the lifting plate 61 is moved to the position of the connecting shaft 71, the connecting shaft 71 enters the connecting groove 62. As the lifting plate 61 is lifted, the connecting shaft 71 will contact the ball bearings 641 on the surface of the support block 64. With continuous lifting, the connecting shaft 71 will drive the support block 64 to descend, and the return spring 631 will be compressed. When the lower surface of the sliding block 63 contacts the pad 632, the support block 64 will also contact the bottom surface of the through groove 621. The return spring 631 will retract into the cylindrical groove 633. The lifting plate 61 will support the support block 64 and the sliding block 63. At this time, the connecting shaft 71 enters the through groove 621, and the lifting operation of the slag hopper 7 will begin.

[0047] When the slag hopper 7 dumps the slag inside, the slag hopper 7 will flip over. At this time, the ball bearing 641 below the connecting shaft 71 can make the connecting shaft 71 rotate better, and the through groove 621 can prevent the connecting shaft 71 from falling off the hanging plate 61.

[0048] like Figure 4-9 As shown, in this embodiment, a connector 51 is fixedly provided at the lower end of the hanging plate 5, and a snap-fit ​​groove 513 is provided on the lower end face of the connector 51. The size of the snap-fit ​​groove 513 is adapted to the size of the hanging plate 61.

[0049] The inner wall of the snap-fit ​​groove 513 is symmetrically provided with a sliding groove 512. The sliding groove 512 communicates with the snap-fit ​​groove 513. A trapezoidal snap block 53 is slidably arranged in the sliding groove 512. A snap-fit ​​spring 532 is symmetrically fixedly connected between the snap block 53 and the inner wall of the sliding groove 512.

[0050] The upper outer side of the hanging plate 61 is provided with a slot 611 that is compatible with the card block 53.

[0051] Specifically, the two combined hanging plates 61 are installed into the snap-fit ​​groove 513. During the upward movement of the hanging plate 61, the snap-fit ​​block 53 will first retract into the sliding groove 512, and the snap-fit ​​spring 532 will compress it. After the upper end of the hanging plate 61 is fully inserted into the snap-fit ​​groove 513, the snap-fit ​​block 53 will enter the snap-fit ​​groove 611 through the snap-fit ​​spring 532. At this time, the connection between the hanging plate 61 and the connector 51 is completed. The operation is simple.

[0052] like Figure 6-9 As shown, in this embodiment, the side of the card block 53 is provided with an inclined slot 531 that communicates with the outside. The two sides of the connector 51 are provided with straight slots 511 that communicate with the inclined slot 531 at positions relative to the inclined slot 531. A pressing block 52 is provided on the outside of the straight slot 511. A sliding shaft 521 is symmetrically fixedly connected between the two pressing blocks 52. The sliding shaft 521 slides in the inclined slot 531 and the straight slot 511, and the pressing block 52 slides on the outer wall of the connector 51.

[0053] Specifically, when the hanging plate 61 needs to be disassembled for maintenance, the pressing block 52 needs to be pushed down simultaneously. The sliding shaft 521 squeezes the locking block 53, which can retract the locking block 53 into the sliding groove 512. At this time, the locking block 53 is disconnected from the locking groove 611, and the hanging plate 61 is disconnected from the connector 51. Pushing only one side of the pressing block 52 cannot make the sliding shaft 521 move down.

[0054] like Figure 11 As shown, in this utility model, an installation groove 623 is provided on the bottom surface of the through groove 621. A push switch 624 is fixedly installed in the installation groove 623. When the connecting shaft 71 drives the support block 64 to move to the bottom of the through groove 621, the support block 64 will squeeze the push switch 624. At this time, the push switch 624 will give an electrical signal to notify the lifting personnel, and the formal lifting operation can be carried out.
