The second adjusting device can be connected to the vibrating rod, and the vibrating device can cooperate with the vibrating rod, wherein the vibrating device and the second adjusting device can be switchably and movably arranged on the adjusting member in a third direction.

[0003] However, each existing set of rappers needs to be equipped with a set of driving mechanisms, which is costly. Therefore, it is necessary to improve them. Summary of the invention

[0004] The utility model aims to provide a smelting boiler vibrating device, which solves the problem that each existing set of vibrators needs to be equipped with a set of driving mechanisms, resulting in high costs.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a smelting boiler vibrating device, including a motor reducer, a linkage shaft, a fixed vibrating hammer shaft and a boiler tube bundle vibrating beam, a driven sprocket is arranged at the end of the output shaft of the motor reducer, a driving sprocket is arranged at the end of the linkage shaft close to the motor reducer, and a chain is arranged between the driving sprocket and the driven sprocket, a pulley bracket is welded to the shaft body of the linkage shaft, and a pulley bearing is arranged at the end of the pulley bracket away from the linkage shaft, a pulley track is installed on the outer side of the shaft body of the fixed vibrating hammer shaft through a bearing, the pulley track is slidably connected to the pulley bearing, a vibrating rod assembly is arranged at the end of the pulley track, and a vibrating pile is welded on the surface of the boiler tube bundle vibrating beam.

[0006] The principle of the utility model is that when in use, three rapping rod assemblies are connected by coaxial shafts, and the hammer lifting devices of the three rapping rod assemblies are evenly arranged on the fixed rapping hammer shaft. A motor reducer is installed on one side of the fixed rapping hammer shaft, and the linkage shaft is driven to rotate by the motor reducer. During the rotation, the pulley bracket fixed on the linkage shaft rotates synchronously. During the rotation, the pulley bearing at the top of the pulley bracket rolls in the pulley track on the rapping rod assembly to lift the rapping rod assembly. When the pulley bearing has completed the pulley track, the pulley bearing is disengaged from the pulley track, and the rapping rod assembly falls by its own gravity and strikes on the rapping pile. The rapping pile is tightly connected to the boiler tube bundle rapping beam, so as to achieve the purpose of striking the boiler tube bundle rapping beam, reduce the operation failure of the motor, and save electricity costs at the same time.

[0007] The beneficial effect of the utility model is that three rapping rod assemblies are connected to a fixed rapping hammer shaft in the form of coaxial axes, and then a linkage shaft is driven to rotate by a motor reducer, and three pulley brackets with pulley bearings that cooperate with the rapping rod assemblies are arranged on the linkage shaft. This reduces the number of motor reducers used for two rapping machines, reduces the operating failures of the motor reducer of the boiler rapping, and saves electricity costs.

[0008] Furthermore, the number of the pulley brackets is three, and the three pulley bracket arrays are distributed on the linkage shaft. By setting the three pulley brackets, it is convenient to set three sets of pulley bearings at the same time.

[0009] Furthermore, the rapping rod assembly includes a rapping block welded to the pulley track, a positioning block is clamped inside the rapping block, a protective pad is fixedly connected to the surface of the positioning block, and the protective pad is in contact with the rapping pile. The rapping pile can be rapped by the impact force of the rapping block's free swing.

[0010] Furthermore, the protective pad is in contact with the rapping block and is made of rubber. By providing the protective pad, the hard contact between the rapping block and the rapping pile can be reduced.

[0011] Furthermore, a rubber bead is fixedly connected to one side of the positioning block located inside the rapping block, and the rubber bead is clamped with the rapping block. The setting of the rubber bead has a certain locking effect on the positioning block.

[0012] Furthermore, the positioning block is square and made of steel. The installation of the protective pad is facilitated by the arrangement of the positioning block. BRIEF DESCRIPTION OF THE DRAWINGS

The number of pulley brackets 9 is three, and the three pulley brackets 9 are arrayed and distributed on the linkage shaft 4. Through the arrangement of three pulley brackets 9, it is convenient to simultaneously arrange three groups of pulley bearings 10.

[0019] like Figure 3 As shown, the rapping rod assembly 7 includes a rapping block 71 welded to the pulley track 6, a positioning block 73 is clamped inside the rapping block 71, and a protective pad 72 is fixedly connected to the surface of the positioning block 73, and the protective pad 72 is in contact with the rapping pile 8. The rapping pile 8 can be rapped by the impact force of the free swing of the rapping block 71. The protective pad 72 is in contact with the rapping block 71 and is made of rubber. By the provision of the protective pad 72, the hard contact between the rapping block 71 and the rapping pile 8 can be reduced.
