[0005] To solve the above technical problems, the utility model adopts the technical scheme that

[0006] A rotation-preventing structure of a slag grabbing grab in a vortex well, which comprises two stop blocks and two stops, the slag grabbing grab is suspended on an upper beam through a steel wire rope to realize the lifting of the slag grabbing grab, the two stop blocks are fixed on the two open end side walls of the slag grabbing grab, the stop adopts a channel steel, and the two stops are vertically arranged on the two sides of the inner side wall of the vortex well, so that when the slag grabbing grab is opened to move downward in the vortex well, the two stops are arranged in front of the rotating direction of the stop blocks.

[0007] Further, the two stop blocks are fixed on the two open end side walls of the slag grabbing grab, the stop adopts a channel steel, the four stops are vertically and symmetrically arranged in two groups on the two sides of the inner side wall of the vortex well, and a vertical limiting groove is formed between the two stops in each group.

[0008] Further, the width of the limiting groove is greater than the width of the stop block.

[0009] Further, a plurality of counterweight blocks are arranged on the two side walls of the slag grabbing grab through connecting bolts.

[0010] Compared with the prior art, the utility model has the beneficial effects that

[0011] 1. The stop block and the stop are matched, the problem that the slag grabbing grab is rotated under the impact of water flow is effectively prevented, the operation efficiency is improved, the labor cost is reduced, and the damage of equipment caused by the rotation of the grab is eliminated.

[0012] 2、 The utility model discloses a counterweight is arranged on the both sides of the slag grabbing grab bucket, and the stability of the grab bucket is further improved.

[0013] 3、 The utility model discloses simple structure, easy operation, high practicality. DRAWINGS

[0018] Embodiment 1

[0019] The utility model will be further explained below in connection with the drawings and embodiment.

[0020] As Figures 1-2 Shown, a kind of anti-rotation structure of slag grabbing grab bucket in cyclone well, including two stop blocks 3 and two stops 4, slag grabbing grab bucket 1 is hung on the overhead crossbeam by wire rope, realize the lifting of slag grabbing grab bucket 1, the two stop blocks 3 are fixed in the two sides of the side wall of the two open ends of slag grabbing grab bucket 1, the stop 4 is made of channel steel, two stops 4 are vertically arranged in the inner side wall of cyclone well 2 two sides, so that the two stops 4 are located in the rotation direction front of stop block 3 when slag grabbing grab bucket 1 opens and moves down to cyclone well 2, the two side walls of the slag grabbing grab bucket 1 are equipped with several counterweight blocks 5 by connecting bolt 6. Embodiment 2

[0021] As Figure 3 Shown, a kind of anti-rotation structure of slag grabbing grab bucket in cyclone well, including two stop blocks 3 and four stops 4, the two stop blocks 3 are fixed in the two sides of the side wall of the two open ends of slag grabbing grab bucket 1, the stop 4 is made of channel steel, four stops 4 are vertically symmetrically arranged in the inner side wall of cyclone well 2 two sides in two groups, vertical limiting slot is formed between every two stops 4 in each group, the width of the limiting slot is greater than the width of stop block 3, the two side walls of the slag grabbing grab bucket 1 are equipped with several counterweight blocks 5 by connecting bolt 6.

[0022] The working process of the utility model:

[0023] When the embodiment 1 is used, the grab bucket 1 is hung on the upper beam by the steel wire rope, and the grab bucket 1 moves downward after being opened and facing the cyclone well 2. When the grab bucket 1 moves into the cyclone well 2, the flow of the water for washing the slag in the cyclone well is large, and the grab bucket 1 is impacted by the water flow and tends to rotate. At this time, the stop blocks 3 on the two sides are abutted against the stop 4 under the action of the water flow, so that the grab bucket 1 stops rotating and moves downward along the stop 4. During the descending process, the counterweight blocks 5 on the two sides further improve the stability of the grab bucket, effectively prevent the problem that the grab bucket 1 is impacted by the water flow and rotates, improve the operation efficiency, reduce the labor cost, and eliminate the equipment damage caused by the rotation of the grab bucket;

[0024] When the embodiment 2 is used, the operation personnel align the stop blocks 3 with the limiting grooves when the grab bucket 1 descends, and the stop blocks 3 on the two sides enter the limiting grooves and descend along the limiting grooves when the grab bucket 1 moves into the cyclone well 2. The problem that the grab bucket 1 is impacted by the water flow and rotates is effectively prevented, the operation efficiency is improved, the labor cost is reduced, the equipment damage caused by the rotation of the grab bucket is eliminated, and the stability of the grab bucket is further improved by the counterweight blocks 5 on the two sides.
