[0034] Please refer to the attached Figure 1-Figure 3 , showing a slag lifting device for removing concrete from a working gate shaft at the bottom of a dam body provided in an embodiment of the present application, comprising: a bracket system 3, an electric hoist 4, a pull rope system 5, and a magnetic stabilization structure composed of a magnetic block 8 and an electromagnetic suction plate 7.

[0035] The support system 3 is fixedly installed on the top of the dam body 1. The support system 3 has a slideway 304 located directly above the working gate shaft 2. The main body of the electric hoist 4 is slidably installed on the slideway 304. The lifting rope of the electric hoist 4 is connected to a slag bucket 9.

[0036] The electric hoist 4 reels in / releases the lifting rope (wire rope) to lift / lower the slag bucket 9; the slag bucket 9 is filled by the construction workers at the bottom of the working gate shaft 2, and the electric hoist 4 reels in the lifting rope to lift the slag bucket 9. After the slag bucket 9 reaches the upper end of the working gate shaft 2, the operator of the slag lifting device slides the electric hoist 4 and the slag bucket 9 to one side through the rope system 5 to unload the concrete garbage in the slag bucket 9.

[0037] A fixing frame 6 is fixedly installed on the slide 304, and the pull rope system 5 includes a first wheel body 501, a second wheel body 502, a third wheel body 503, and a pull rope 504.

Both ends of the pull rope 504 are fixedly connected to the side of the first wheel body 501, and the pull rope 504 forms a ring. The pull rope 504 is located on the outside of the second wheel body 502 and the third wheel body 503.

[0038] The operator pulls the pull rope 504 at the third wheel body 503 to control the electric hoist 4 to slide on the slide 304; for example: pulling the pull rope 504 located above the third wheel body 503 makes the electric hoist 4 slide toward the operator; pulling the pull rope 504 below the third wheel body 503 makes the electric hoist 4 slide away from the operator.

[0039] An electromagnetic suction plate 7 is fixedly connected to the fixed frame 6, and a magnetic block 8 is fixedly connected to the main body of the electric hoist 4. When the main body of the electric hoist 4 slides to just above the center of the working door shaft 2, the electromagnetic suction plate 7 is controlled to be energized so that the electromagnetic suction plate 7 tightly absorbs the magnetic block 8, that is, the main body of the electric hoist 4 is kept fixed to the fixed frame 6, so that during the lifting process, the main body of the electric hoist 4 will not slide, the lifting is stable and reliable, and the risk of safety accidents is reduced.
