[0023] like Figure 1-9 The utility model shows a slab cut head waste collection device, which includes a chute 1 matched with the fallen slab cut head 6, the chute 1 is arranged obliquely and fixed on the ground by a bracket 2, a collection box 3 for collecting and accommodating the slab cut head 6 is arranged below the chute 1, and a hanger 4 for lifting the collection box 3 is also arranged on the collection box 3;

[0024] An upper pin shaft 304 and a lower pin shaft 305 are respectively arranged on both sides of the collection box 3; the hanger 4 includes a lifting ear 401, and a plate hook 402 is welded on both sides of the lifting ear 401, and a long strip-shaped shaft hole 404 matching with the lower pin shaft 305 is arranged below the plate hook 402, and a hook groove matching with the upper pin shaft 304 is arranged near the middle position on the plate hook 402.

[0025] In this solution, the lower side of the plate hook cooperates with the lower pin through the long strip-shaped shaft hole (rotation plus a certain displacement), and the hook groove and the upper pin are engaged. When lifting is required, the plate hook is controlled to fall by the crane, so that the lower pin cooperates with the upper part of the shaft hole, and then the plate hook is controlled to move in the direction of the upper pin, so that the upper pin enters from the opening of the hook groove, and then the crane rises, and the upper pin enters the hook groove and clamps. At this time, the collection box and the plate hook are stably matched, and lifting can be achieved. When it is necessary to unload the material when lifting to the scrap area, the crane falls, so that the upper pin rises relatively from the bottom of the hook groove to the opening of the hook groove, and then the crane is controlled to move horizontally, so that the upper pin is separated from the hook groove. When the plate hook is close to vertical, the crane rises, and the shaft hole of the plate hook rotates with the lower pin. Because the lower pin is located on one side of the collection box, the collection box will be flipped under the action of gravity during the crane's ascent, achieving the purpose of unloading. After unloading, refer to the above operation, enter the lifting state again and hoist it back to its position. After returning to its original position, pull the plate hook backwards. At this time, the limit column contacts the upper edge of the collection box, so that the plate hook remains in a position that does not hinder operation and is convenient for the crane hook to lift it.

[0026] Preferably, the chute 1 comprises a slide plate 102 made of thick steel plate, and ear plates 101 are welded on both sides of the slide plate 102. The ear plates 101 have screw holes 104 and are fixedly connected to the fixing frame by bolts; the slide plate 102 is also provided with a socket 103 that matches the bracket 2.

[0032] Preferably, a support slat or a support net is arranged between the two rollers near the chute, and the support slat is fixed on the rollers through a bracket to support the cut ends to prevent them from falling or getting stuck in the gap of the rollers. The specific position of the support slat is based on the position (of the cut ends) where the slab reaches after cutting on the production line, usually between the two rollers near the chute.

[0033] In this solution, the connection relationship between the various components can be achieved by welding, bolt connection and other matching methods in the prior art. Example

[0034] This embodiment discloses a slab cut end waste collection device, comprising a chute 1, a bracket 2, a collection box 3, a hanger 4, a roller 5, a slab cut end 6, a movable frame 7, and a slide plate 8. The chute 1 is used for the slab cut end to slide freely into the collection box, the bracket 2 is used to ensure the stability of the chute 1, the collection box 3 is used to collect and transport the discarded slab cut ends, and the hanger 4 is used to lift the collection box 3.

[0035] Among them, the chute 1 includes an ear plate 101, a slide plate 102, a socket 103 and a screw hole 104. The bottom of the chute 1 is a slide plate 102 with a socket 103. The bracket 2 fixed underground is welded to the slide plate 102 through the socket 103. An ear plate 101 with a screw hole 104 is welded on both sides of the slide plate 102. The ear plates 101 on both sides are fixed to the fixing frames at both ends by bolts to keep the chute 1 stable as a whole. The collecting box 3 includes a bottom plate 301, a side plate 302, an end plate 303, an upper pin shaft 304, a lower pin shaft 305, a fixing plate 306, a slat 307 and a water leakage hole 308. The collecting box 3 is arranged below the end of the chute 1. A side plate 302 is welded on both sides of the bottom plate 301, and an end plate 303 is welded on the front and rear ends respectively. An upper pin shaft 304 and a lower pin shaft 305 are welded on the upper and lower parts of the outer sides of the side plates 302 respectively. The other ends of the upper pin shaft 304 and the lower pin shaft 305 are welded to the fixing plate 306. The fixing plate 306 and the side plates 302 are welded and reinforced by slats 307. The hanger 4 includes a lifting ear 401, a plate hook 402, a limiting column 403 and an axial hole 404. A plate hook 402 with an axial hole 404 at the lower end is welded on both sides of the lifting ear 401. The lower pin shaft 305 is arranged inside the pin shaft hole 404, and a limiting column 403 is welded on the inner upper part of the plate hook 402.

[0036] Preferably, a slide plate 8 is provided between the chute 1 and the roller 5, and the slide plate 8 is welded to the movable frame 7 through a crossbeam, so as to prevent the slab cut head 6 from falling into the lower part of the roller after being separated from the slab.

[0037] Preferably, it also includes a plate hook 402 that cooperates with the upper pin shaft 304 and the lower pin shaft 305. When the hanger 4 is in working state, the plate hook 402 can be synchronously locked with the upper pin shaft 304 and the lower pin shaft 305 to prevent the collection box 3 from falling off.

[0038] Preferably, a plurality of groups of water leakage holes 308 are arranged on the bottom plate 301 of the collecting box 3 , so as to prevent the accumulation of cooling water or other liquid in the collecting box 3 .

[0039] Preferably, it also includes limit posts 403, and two groups of limit posts 403 are respectively welded to the inner sides of the plate hooks 402. When the device is in a non-working state, the limit posts 403 drive the hanger 4 to stop on the side plate 302 to prevent the hanger 4 from falling further.

[0040] When the flame cutting machine separates the slab produced by the continuous casting machine from the slab head 6, the moving frame 7 drives the roller 5 to move backward, and a certain distance appears between the two rollers 5, while the slab head 6 continues to be transported forward with the roller 5. When the slab head 6 leaves the support of the roller 5, it falls into the chute 1 through the slide 8. The slab head 6 finally slides into the collection box 3 by its own gravity and the inclination angle of the chute 1. Then, the crane is used to move the hanger 4 from the non-working state tilted backward to the working state tilted forward, and the hanger 4 is lifted, thereby driving the collection box 3 to be transported to the waste area. At this time, the upper pin 304, the lower pin 305 and the plate hook 402 are locked and matched with each other to ensure the stability of the collection box 3 during the lifting process. After the lifting is completed, the collection box 3 is put back to its original position to wait for the next collection of the slab head 6, and the moving frame 7 drives the roller 5 to move forward, and the normal working distance between the two rollers 5 is restored.

[0041] The structure of the utility model can not only collect and carry slab heads with high heat, large weight and irregular shapes, but also prevent accidents such as burns or scratches caused by the collection process, thus ensuring personal safety. At the same time, the leakage hole 308 can be used to prevent cooling water from accumulating in the collection box 3 and causing an impact. During the lifting process, the plate hook 402 matched with the upper pin shaft 304 and the lower pin shaft 305 can realize the smooth transportation of the collection box 3, thus avoiding the situation that the slab head 6 often falls during the lifting process in traditional lifting, thereby preventing unexpected shutdown accidents, reducing unnecessary maintenance workload, and realizing industrial automation.
