DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1: Refer to the attached specification Figure 1-4 The utility model is a gas turbine air tightness detection tooling equipment, including a support frame 1, see Figure 1 The support frame 1 is internally rotatably connected with a bidirectional threaded rod 2, and both ends of the bidirectional threaded rod 2 are fixedly connected with handles 3. The support frame 1 is internally fixedly connected with a guide rod 4, and the outer wall of the guide rod 4 is slidably connected with a fixing plate 5. The fixing plate 5 is slidably connected to the top of the support frame 1. The fixing plate 5 is connected to the outer wall of the bidirectional threaded rod 2 by threads, and a sleeve 6 is fixedly installed on one side of the fixing plate 5. For details, see Figure 3 The inner wall of the sleeve 6 is fixedly connected with a blocking airbag 7, the inside of the blocking airbag 7 is fixedly connected with a pressure ring 8, a plurality of air holes 9 are opened inside the pressure ring 8, one side of the blocking airbag 7 is fixedly connected with a connecting pipe 10, and one end of the connecting pipe 10 is connected with an annular airbag 11;
[0022] One side of the annular airbag 11 is fixedly connected to the inside of the fixing plate 5, a spring 12 is fixedly installed inside the annular airbag 11, one side of the annular airbag 11 is fixedly connected to a pressure plate 13, the pressure plate 13 is sleeved on the outer wall of the connecting pipe 10, the pressure plate 13 is slidably connected to the inside of the fixing plate 5, the inside of the fixing plate 5 is fixedly connected to a cylinder 14, the cylinder 14 is inserted into the inside of the annular airbag 11, and the blocking airbag 7 is fixedly connected to the outer wall of the cylinder 14, see Figure 2 The outer wall of the cylinder 14 is connected to an air pipe 15, which is plugged into the interior of the fixed plate 5. One end of the air pipe 15 is fixedly connected to a gas generator 16. Figure 4The outer wall of the guide rod 4 is provided with a limit plate 17, which is slidably connected to the inside of the fixed plate 5, and the top of the limit plate 17 is rotatably connected to a threaded rod 18, which is threadedly connected to the inside of the fixed plate 5, see Figure 1 A support block 19 is fixedly connected to the top of the support frame 1.
[0023] It should be noted that, when the staff detects the sealing of the gas turbine, firstly, the gas turbine is placed on the support block 19, and the handle 3 is turned, so that the handle 3 drives the bidirectional threaded rod 2 to rotate, and then the bidirectional threaded rod 2 drives the two fixing plates 5 to move toward the direction of the gas turbine on the support block 19, so that the fixing plate 5 drives the sleeve 6 to be sleeved on the outer wall of the port of the gas turbine, so that the port of the gas turbine is inserted into the inside of the blocking airbag 7. As the staff continues to turn the handle 3, the gas turbine will be pressed against the pressure plate 13 through the pressure ring 8 inside the blocking airbag 7. , let the pressing plate 13 slide along the inside of the fixing plate 5 and squeeze the annular airbag 11 to shrink. The shrinkage of the annular airbag 11 will discharge the gas into the inside of the blocking airbag 7 through the connecting pipe 10. The blocking airbag 7 receives the gas and expands. Since the outer wall and the inner wall of the blocking airbag 7 are respectively fixedly connected to the inner wall of the sleeve 6 and the outer wall of the cylinder 14, the blocking airbag 7 can only be tightly fitted on the gas turbine port when it expands, so that the port of the gas turbine is sealed by the expansion of the blocking airbag 7, so as to achieve the effect of quickly sealing the port of the gas turbine, which is convenient for the staff to seal the gas turbine;
[0024] Furthermore, after the port of the gas turbine is sealed, the staff can start the gas generator 16 to make the gas generator 16 work to exhaust gas into the gas pipe 15, and then make the gas pipe 15 discharge gas into the gas turbine through the cylinder 14, until the internal pressure of the gas turbine reaches the detection requirement, and then stop increasing the pressure inside the gas turbine. At this time, the staff can detect the connection seals at various locations of the gas turbine to determine whether the airtightness of the connection seals at various locations is qualified;
[0025] Furthermore, after the staff turns the handle 3 and finally seals the port of the gas turbine, the staff can stop turning the handle 3 and start turning the threaded rod 18, so that the threaded rod 18 descends along the inside of the fixed plate 5 through the thread, and squeezes the limiting plate 17 to descend along the inside of the fixed plate 5, so that the limiting plate 17 is stuck on the outer wall of the guide rod 4, and the fixing plate 5 is limited and fixed, thereby improving the stability of the fixing plate 5 and preventing the fixing plate 5 from being displaced by the pressure when the pressure is increased inside the gas turbine, resulting in the failure to reach the detection pressure inside the gas turbine.
