DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the above is described with the upper side of Figure 3 as the upper side). Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5, the present utility model provides a technical solution: a welding device for a cutter head component of a shield machine, including a support frame 1 and a cutter head 2. The cutter head 2 is located at the upper end of the support frame 1. A base 3 is provided on one side of each cutter head component to be welded. An elevating seat 4 is provided above the base 3. A telescopic seat 12 is provided on one side of the elevating seat 4. A driving motor 8 is provided at the lower end of the telescopic seat 12. The lower end of the output shaft of the driving motor 8 is connected to a connecting rod 10. One end of the connecting rod 10 is connected to a moving block 9. A welding assembly 11 for welding the cutter head component is provided at the lower end of the moving block 9. By controlling the rotation of the connecting rod 10 by the driving motor 8, the welding assembly 11 welds along the connection position between the cutter head component and the cutter head 2;

[0019] The welding assembly 11 includes a fixing plate 111, fixed ear plates 112, adjusting bolts 113, rotating blocks 116, fixing blocks 114 and welding torches 115. The fixing plate 111 is fixed to the lower end of the moving block 9. Two fixed ear plates 112 are symmetrically provided at the lower end of the fixing plate 111. The adjusting bolts 113 pass through the two fixed ear plates 112 and nuts are provided at the threaded ends of the adjusting bolts 13. The rotating blocks 116 are located between the two fixed ear plates 112 and are fixed to the outer side surfaces of the adjusting bolts 13. The fixing blocks 114 are provided at the lower ends of the rotating blocks 116. The welding torches 115 are obliquely fixed to the rotating blocks 116 and the welding torches 115 face the welding positions of the cutter head components. Before the welding work starts, it is necessary to rotate the adjusting bolts 113 to adjust the inclination angles of the welding torches 115 so that the welding torches 115 can weld along the connection positions of the cutter head components, improving the universality of use.

[0020] Further, in order to adjust the position of the welding assembly 11 to correspond to the welding position of the cutter head component, a lifting hydraulic cylinder 5 is provided between the base 3 and the elevating seat 4, and a telescopic hydraulic cylinder 6 is provided between the elevating seat 4 and the telescopic seat 12.

[0021] Further, in order to ensure that the welding torch 115 moves along the welding position, an arc-shaped guide rail 7 adapted to the welding track of the cutter head component is fixed to the lower end of the telescopic seat 12, and the moving block 9 is slidably connected to the chute 13 at the lower end of the arc-shaped guide rail 7.

[0022] Further, in order to be applicable to the welding tracks of cutter head components on cutter heads 2 of different models of shield machines, three connecting parts 14 are provided between the arc-shaped guide rail 7 and the telescopic seat 12. The three connecting parts 14 are respectively located at both ends and the middle position of the arc-shaped guide rail 7. The connecting part 14 includes a support block 141 and a connecting bolt 142. The support block 141 is fixed to the upper end of the arc-shaped guide rail 7. The connecting bolt 142 passes through the arc-shaped guide rail 7 and is threadedly connected to the telescopic seat 12. It is convenient to replace the arc-shaped guide rail 7 with different moving tracks through the connecting bolt 142, ensuring the universality of use of this welding device.

[0023] Among them, the input ends of the lifting hydraulic cylinder 5, the telescopic hydraulic cylinder 6, and the driving motor 8 are all electrically connected to the output end of the control switch, which is convenient for workers to control the operation away from the welding position.

[0024] During use: According to the inherent welding trajectory of the cutter head component, select a suitable arc-shaped guide rail 7, then install a matching moving block 9, and install the moving block 9 and the connecting rod 10 together on the output shaft of the driving motor 8. Adjust the position of the welding assembly 11 by adjusting the lifting hydraulic cylinder 5 and the telescopic hydraulic cylinder 6, so that the welding torch 115 is located at the starting position of the cutter head component. Then adjust the adjusting bolt 113 so that the welding torch 115 is aligned with the connection position of the cutter head component and the cutter head 2. Start the driving motor 8 to make the welding torch 115 rotate, and start the welding operation along the welding trajectory.

[0025] The utility model can quickly weld the cutter head component to the cutter head 2. In the whole process, only workers need to operate away from the welding position, without performing welding operations at close range, which protects the physical health of workers. At the same time, it improves the welding efficiency and ensures uniform weld seams.
