[0018] Reference Figure 1 - Figure 5 A surface grinding device for repairing a main steam valve includes a main body 1. A grinding disc 101 is provided on one side of the main body 1, and a collecting ring 102 is provided on one side of the grinding disc 101. A connecting pipe 103 is fixedly connected to the top of the collecting ring 102. A support mechanism for supporting the connecting pipe 103 is provided on the surface of the connecting pipe 103. Two fixing rings 2 are fixedly sleeved on the surface of the main body 1. Two sliding grooves 201 are symmetrically opened on the surface of the two fixing rings 2. The same first sliding plate 203 is slidably connected inside the two sliding grooves 201. An adjustment mechanism for adjusting the connecting pipe 103 is provided on one side of each of the two first sliding plates 203. By setting the collecting ring 102, it is possible to prevent debris from entering other equipment.

[0019] Preferably, the support mechanism includes a support rod 3, which is disposed on one side of the main body 1. A through groove 304 is formed on one side of the support rod 3. A connecting pipe 103 is slidably connected inside the through groove 304. A pressure plate 403 is slidably connected to one side of the through groove 304. Multiple pressure cones 404 are fixedly connected to the surface of the pressure plate 403 near the connecting pipe 103. The pressure plate 403 and the pressure cones 404 are all configured to cooperate with the connecting pipe 103. By setting the pressure plate 403, the connecting pipe 103 can be constrained. The pressure plate 403 is far away from the connecting pipe 103. Two connecting rods 401 are fixedly connected to one side of the pipe 103. Both connecting rods 401 are slidably connected to one side of the support rod 3. The other end of the two connecting rods 401 is fixedly connected to the same pull plate 4. The surface of the two connecting rods 401 near the pressure plate 403 is fitted with a second tension spring 402. One end of the two second tension springs 402 is fixedly connected to one side of the through groove 304, and the other end of the two second tension springs 402 is fixedly connected to one side of the pressure plate 403. The connecting pipe 103 can be supported by the support rod 3.

[0020] Preferably, the adjusting mechanism includes a sleeve 204, which is fixedly connected to one side of the first slide plate 203. A second slide plate 301 is slidably connected inside the sleeve 204. The second slide plate 301 is fixedly connected to one side of the support rod 3. A locking post 302 is fixedly connected to the surface of the second slide plate 301 near the fixing ring 2. The locking post 302 is slidably connected to one side of the first slide plate 203. A first tension spring 303 is sleeved on the surface of the locking post 302. The locking post 302 can be constrained by the first tension spring 303. One end of the first tension spring 303 is fixedly connected to one side of the second slide plate 301, and the other end of the first tension spring 303 is fixedly connected to one side inside the sleeve 204. The surface of the fixing ring 2 has multiple locking grooves 202, which are evenly arranged in a ring. The multiple locking grooves 202 are all configured to cooperate with the locking post 302. The connecting pipe 103 can be adjusted by the locking post 302.

[0021] Working Principle: In use, the connecting pipe 103 is connected to an external collection mechanism. A collection ring 102 is installed at the other end of the connecting pipe 103, and the collection ring 102 is installed on one side of the grinding disc 101. When the grinding disc 101 grinds the main steam valve, the collection ring 102 collects the grinding debris, preventing it from entering other equipment. Two fixing rings 2 are installed on the surface of the main body 1, and both fixing rings 2 are connected to the connecting pipe 103 via support rods 3, thus supporting the connecting pipe 103. When the position of the connecting pipe 103 needs to be adjusted, the pull plate 4 on one side of the support rod 3 is pulled first. A pressure plate 403 is installed on one side of the pull plate 4, and the pressure plate 403 initially contacts the connecting pipe 103 to prevent the connecting pipe 103 from slipping during use. This phenomenon allows the pressure plate 403 to be pulled by the pull plate 4, thus releasing the constraint on the connecting pipe 103. This allows the connecting pipe 103 to be adjusted in length again according to the adjusted position. A locking pin 302 is also installed on one side of the support rod 3, and the locking pin 302 is connected to the locking groove 202 on the surface of the fixing ring 2. Since the support rod 3 is connected to the fixing ring 2 through the first tension spring 303, when the pressure plate 403 is pulled to the limit position, the support rod 3 will also move accordingly, thereby moving the locking pin 302 out of the locking groove 202. After the locking pin 302 has moved, the support rod 3 can be rotated as needed. After the position adjustment is completed, the pull plate 4 can be reset. After the pull plate 4 is reset, the pressure plate 403 and the locking pin 302 will also be reset, thus ensuring that the connecting pipe 103 can continue to be fixed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
