[0019] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0020] A plasma cladding welding device comprises a workbench 1, on the workbench 1 is placed a display device 11 (the display device 11 may be a display electronic device such as a computer display screen or a television), four hydraulic telescopic columns A2 are symmetrically fixedly installed on the upper surface of the workbench 1, a hanging plate 3 with a vent is fixedly installed between the upper surfaces of the four hydraulic telescopic columns A2, a plasma cladding welding device body 4 is installed through the upper surface of the hanging plate 3, a shielding cover 31 for easy disassembly is installed on the hanging plate 3, the shielding cover 31 is formed by welding four lead plates end to end, a monitor body 5 is fixedly installed on the lower surface of the hanging plate 3, the monitor body 5 is electrically connected to the display device 11, a clamping device 6 is installed through the upper surface of the workbench 1, and the plasma cladding welding device body 4, the monitor body 5 and the clamping device 6 are all located on the inner side of the shielding cover 31;

[0021] When using, combine Figure 1 and Figure 2As shown, the hydraulic cylinder 7 to be repaired is placed in the repair area of ​​the workbench 1 and is clamped and fixed by the clamping device 6. Then, the hydraulic telescopic column A2 is used to drive the lifting plate 3 and the shielding cover 31 to move downward. When the shielding cover 31 blocks the hydraulic cylinder 7 to be repaired, the plasma cladding welding device body 4 is started to perform plasma cladding welding on the hydraulic cylinder 7 to be repaired. During the repair operation, the monitor body 5 can be used to transmit the picture in the working area to the display device 11 for display, and the hydraulic cylinder repair process can be viewed in real time on the display device 11. After the repair is completed, the plasma cladding welding device body 4 is stopped, and the hydraulic telescopic column A2 is used to drive the lifting plate 3 and the shielding cover 31 to move up and reset. After the clamping device 6 is released to fix the hydraulic cylinder 7 to be repaired, the hydraulic cylinder 7 to be repaired can be removed from the workbench 1. Compared with the prior art, the plasma cladding welding device can block the strong light and radiation generated during the operation when repairing the hydraulic cylinder, so as to avoid harm to operators passing by or around.

[0022] It should be noted that when the monitor body 5 is installed, the monitoring direction of the monitor body 5 needs to correspond to the operating area of ​​the plasma cladding welding device body 4 .

[0023] In addition, if Figure 3 As shown, an L-shaped support plate 32 is fixedly installed symmetrically on the lower surface of the hanging plate 3, and the front end of the L-shaped support plate 32 is closed to the hanging plate 3, as shown in FIG. Figure 4 As shown, the left and right surfaces of the shielding cover 31 are symmetrically fixed with plug blocks 311, and the rear end outer surfaces of the plug blocks 311 are provided with positioning holes 312. The plug blocks 311 are plugged and installed in the corresponding L-shaped support plate 32, and the right end outer surface of the L-shaped support plate 32 is penetrated and screwed with locking bolts 33, and the inner side ends of the locking bolts 33 are screwed and installed in the corresponding positioning holes 312;

[0024] When the shielding cover 31 and the hanging plate 3 are assembled together, the position of the L-shaped support plate 32 is visually observed, and the plug blocks 311 of the shielding cover 31 are respectively inserted into the corresponding L-shaped support plates 32, and the shielding cover 31 is lifted and hung by the L-shaped support plate 32 through the plug blocks 311. When the plug blocks 311 are inserted to the rear end of the L-shaped support plate 32, the position of the positioning holes 312 corresponds to the position of the locking bolts 33. After the locking bolts 33 are tightened, the inner ends of the locking bolts 33 are screwed into the corresponding positioning holes 312. At this time, the shielding cover 31 is fixedly installed under the hanging plate 3. When removing the shielding cover 31, the reverse operation can be performed;

[0025] In summary, by providing the L-shaped support plate 32 , the insert block 311 and the locking bolt 33 , the disassembly and assembly between the shielding cover 31 and the hanging plate 3 can be made more convenient and quick.

[0026] Specifically, if Figure 5As shown, the clamping device 6 includes two L-shaped clamping plates 61, which are slidably installed in the workbench 1, and a fixing plate 62 is fixedly installed between the lower surfaces of the two L-shaped clamping plates 61, and a hydraulic telescopic column B63 is fixedly installed between the upper surface of the fixing plate 62 and the lower surface of the workbench 1;

[0027] When the clamping device 6 is used, Figure 1 and Figure 5 As shown, after the hydraulic cylinder 7 to be repaired is placed in the repair area, the hydraulic telescopic column B63 can be extended to drive the two L-shaped clamps 61 to move toward the direction of the hydraulic cylinder 7 to be repaired through the fixed plate 62, so that the hydraulic cylinder 7 to be repaired is clamped and fixed on the upper surface of the workbench 1. When releasing the fixation of the hydraulic cylinder 7 to be repaired, the hydraulic telescopic column B63 is contracted to drive the two L-shaped clamps 61 to move upward to release the clamping of the hydraulic cylinder 7 to be repaired.

[0028] Finally, when the shielding cover 31 moves down and contacts the workbench 1, in order to avoid generating loud noise or bumping at its bottom, Figure 1 As shown, a rubber pad 12 is embedded and fixed on the upper surface of the workbench 1. The rubber pad 12 is in a "mouth shape" and is located directly below the shielding cover 31. The rubber pad 12 can be used to replace the workbench 1 to contact the shielding cover 31, which can not only reduce noise but also reduce collision damage to the bottom of the shielding cover 31.
