[0044] Through the above arrangement, the staff places the device base 1 in the designated area, and then starts the test device 12. The test device 12 drives the telescopic end to move vertically through the built-in electric push rod to prepare for testing.

[0045] Reference Figure 2 , 3. The rotating protection mechanism 2 includes a back plate 21, so as to shield the back of the device. The back plate 21 and the side wall of the test device 12 in a vertical state are fixedly connected with a rotating support plate 22 by welding or bolting. The side of the rotating support plate 22 away from the back plate 21 passes through the top of the rotating support plate 22 and is movably connected with a baffle 23 at the bottom for flipping and opening. The baffle 23 is made of tempered glass, which is convenient for staff to observe during testing. The bottom of the back plate 21 close to the test device 12 is fixedly connected to the device base 1 by welding or adhesive, so that the back plate 21 is always in a vertical state. The side wall of the test device 12 is fixedly connected with a connecting block 24 by welding. The top of the connecting block 24 passes through the connecting block 24 and is vertically slidably connected with a pin 25 for plugging. A card slot 26 is opened at the top of the baffle 23. The size of the card slot 26 matches the bottom of the pin 25. The pin 25 and the card slot 26 are plugged in, so that it plays a protective role when in use.

[0046] Through the above arrangement, the staff will push the baffle 23 to rotate, and then the baffle 23 will rotate toward the side of the support column 11, and the slot 26 will rotate to just below the latch 25, and then the latch 25 will slide downward, so that the latch 25 and the slot 26 will be engaged, so that the baffles 23 and the back panel 21 on both sides form a closed space, and then the test is carried out to seal the test space.

[0047] Reference Figure 4, 5, 6, the self-assembly adjustment mechanism 3 includes an adapter plate 31 fixedly connected to the central telescopic end of the bottom of the test device 12, which is used for connection. The bottom of the adapter plate 31 is fixedly connected to the docking block 32 by bolt connection. The bottom of the docking block 32 is detachably connected to the equal height block 33 by a vertical bolt 35 passing through it, so as to facilitate replacement. The bottom of the equal height block 33 is detachably connected to the mounting positioning block 34 by a vertical bolt 35 passing through it, so as to facilitate assembly. The bottom of the mounting positioning block 34 passes through the mounting positioning block 34 and is threadedly connected with the vertical bolt 35. The mounting nut 39 is provided with a threaded hole, and the vertical bolt 35 passes through the mounting nut 39. The threaded hole is threadedly connected with the mounting nut 39, and the docking block 32 is provided with a through threaded hole. The vertical bolt 35 is threadedly connected with the docking block 32 through the threaded hole penetrating the docking block 32, so that the docking block 32 and the equal height block 33 are tightly connected, making the connection of the overall structure tighter. The vertical bolt 35 passes through one side of the bottom of the mounting positioning block 34 and is threadedly connected with a vertical nut 36. The vertical bolt 35 passes through one side of the top of the docking block 32 and is threadedly connected with another vertical nut 36 for limiting the top and the bottom. A through threaded hole is provided at the bottom edge of the mounting positioning block 34, and a circular through hole is provided in the middle of the mounting positioning block 34 to facilitate the penetration of connecting parts.

[0048] Through the above settings, the staff aligns the spiral hole position at the top of the mounting positioning block 34 with the bottom hole position of the equal height block 33, and the top hole position of the equal height block 33 with the bottom hole position of the docking block 32, and then passes the vertical bolt 35 through the mounting positioning block 34, the equal height block 33, and the docking block 32 in sequence, and then simultaneously threadingly connects the vertical nut 36 with the top of the vertical bolt 35 and the bottom of the vertical bolt 35, so that the docking block 32 is connected to the equal height block 33 and the mounting positioning block 34 as a whole, thereby completing the assembly, and then threadingly connects the top of the blade root pattern 312 with the bottom of the long bolt rod 37, so that the top of the blade root pattern 312 is connected to the self-assembly adjustment mechanism 3

[0049] Reference Figure 6The middle part of the mounting positioning block 34 passes through the mounting positioning block 34 and is movably connected with a long bolt rod 37 for locking. The end of the long bolt rod 37 close to the docking block 32 is threadedly connected with the mounting nut 38 through the thread of the outer wall of the long bolt rod 37. The side wall of the long bolt rod 37 away from the bottom of the mounting nut 38 passes through the mounting nut 39 to achieve threaded connection with the mounting nut 39, so that the position of the long bolt rod 37 is limited by the diameter of the mounting nut 39 being larger than the diameter of the central opening of the mounting positioning block 34. The side wall of the long bolt rod 37 away from the mounting nut 39 passes through the sleeve The ring 310 is slidably connected with the collar 310 to block the hole, thereby preventing the long bolt rod 37 from shaking. The side of the long bolt rod 37 away from the bottom of the collar 310 is threadedly connected with the bolt rod nut 311 through the thread of the outer wall, thereby locking the position to prevent shaking. A cylindrical thread groove is provided at the top of the blade root pattern 312. The side of the long bolt rod 37 away from the bottom of the bolt rod nut 311 is threadedly connected with the blade root pattern 312 through the cylindrical thread groove provided at the top of the blade root pattern 312, thereby connecting the blade root pattern 312 to the device.

[0050] Through the above arrangement, the staff then connects the adapter plate 31 to the central telescopic end at the bottom of the test device 12, and then threadably connects the middle part of the long bolt rod 37 to the bolt rod nut 311, and then threadably connects the ring 310 to the long bolt rod 37, and then places the long bolt rod 37 in the middle through hole of the mounting positioning block 34, and then threadably connects the mounting nut 39 to the long bolt rod 37, and then threadably connects the mounting nut 38 to the long bolt rod 37, so that the bottom of the mounting nut 39 fits with the top of the mounting positioning block 34.

[0051] Reference Figure 7 The bottom side wall of the blade root pattern 312 is provided with an L-shaped block 313 for clamping the bottom of the blade root pattern 312. The outer wall of the blade root pattern 312 fits the side wall of the L-shaped block 313 to make the clamping tighter. The side wall of the L-shaped block 313 is provided with a threaded hole. The side wall of the L-shaped block 313 penetrates the threaded hole and is threadedly connected to the horizontal bolt rod 315. The bottom side wall of the blade root pattern 312 is provided with a through threaded hole. The horizontal bolt rod 315 penetrates the bottom side wall of the blade root pattern 312 and is threadedly connected to the blade root pattern 312. Both ends of the horizontal bolt rod 315 are provided with a threaded hole through the outer wall. The thread is threadedly connected with the horizontal nut 314, so that continuous clamping is performed to prevent the bottom from loosening during the test. The bottom of the L-shaped block 313 penetrates the L-shaped block 313 and is threadedly connected with the base fixing screw 316. The bottom of the base fixing screw 316 is threadedly connected with the T-nut 317 through the thread opened on the outer wall of the bottom of the base fixing screw 316. A cylindrical groove is opened on the top of the device base 1, and the bottom of the base fixing screw 316 is plugged into the top of the device base 1, so that the bottom of the L-shaped block 313 and the device base 1 are tightly fixed to prevent accidents.

[0052] Through the above settings, the staff fits the L-shaped block 313 from both sides of the blade root pattern 312, and aligns the threaded holes on the side walls of the L-shaped block 313 with the threaded holes opened at the bottom of the side walls of the blade root pattern 312, and then passes the horizontal bolt rod 315 through the L-shaped block 313 and threadedly connects them to the blade root pattern 312 respectively, and then threadedly connects the two ends of the horizontal bolt rod 315 with the horizontal nut 314, so as to fix the L-shaped block 313 to the blade root pattern 312, and then passes the base fixing screw 316 through the L-shaped block 313 and threadedly connects it to the T-shaped nut 317 inside the device base 1, so as to fix the L-shaped block 313 to the device base 1 through the T-shaped nut 317, thereby fixing the bottom of the blade root pattern 312, so that when the top of the blade root pattern 312 is stretched, the bottom of the blade root pattern 312 continues to be in a fixed state.

[0053] The testing device 12 is a prior art, and its working principle will not be described in detail.

[0054] The implementation principle of a blade root bolt sleeve component testing tool in an embodiment of the present application is as follows: a closed space is formed inside the device during testing by rotating the card slot 26, and the docking block 32 is assembled with the equal height block 33 and the mounting positioning block 34 by penetration of the vertical bolt 35, so that the top of the blade root pattern 312 is connected to the testing device 12 by threaded connection, and then the L-shaped block 313 is fitted with the bottom of the blade root pattern 312, and then the bottom of the blade root pattern 312 is fixed by threaded connection of the horizontal nut 314, so that the testing process is more stable.
