[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] A deformation resistance testing device for special equipment inspection includes: a circular ring 4, which has a set of straight grooves 8, each straight groove 8 having a round rod 9 fixedly connected to the circular ring 4, and a symmetrical square plate 10 fixedly connected to each straight groove 8; a set of upper sliders 17, each disposed in a corresponding straight groove 8, each round rod 9 passing through a corresponding upper slider 17, and each upper slider 17 fixedly connected to a bracket 18; a set of screws 20, each bearing-connected to a corresponding bracket 18; and a set of lifting frames 22, each screw... Each of the lifting frames 22 is threadedly connected to a corresponding vertical rod 23. A set of hydraulic rods 26 are fixedly connected to the corresponding vertical rods 23. The piston rod of each hydraulic rod 26 is connected to a circular tube 29 and a pressure sensor 27. Each pressure sensor 27 is housed within a corresponding circular tube 29. Each circular tube 29 contains a spring 28 and a cylinder 30. Each pressure sensor 27 is fixedly connected to one end of the corresponding spring 28, and each cylinder 30 is fixedly connected to the other end of the corresponding spring 28. The hydraulic rods 26 drive the cylinder 30 to move radially along the ring 4, facilitating the inspection of equipment of different sizes. The springs 28 apply pressure slowly to the equipment.

[0027] The hydraulic rod 26 is of model MOB.

[0028] The pressure sensor 27 is model SBT673.

[0029] Each square plate 10 is respectively connected to a square shaft 15 by bearings. Each square shaft 15 is respectively disposed in a square hole of a square hole shaft 25. Each square hole shaft 25 is respectively connected to a corresponding bracket 18 by bearings. Each square hole shaft 25 is respectively fixedly connected to a transmission bevel gear 24. Each screw 20 is respectively fixedly connected to a power bevel gear 19. Each transmission bevel gear 24 meshes with a corresponding power bevel gear 19. By using bevel gear meshing, when the square shaft 15 rotates, the cylinder 30 and pressure sensor 27 move along the height direction, enabling detection of equipment of different heights and different positions.

[0030] The circular ring 4 is fixedly connected to the cylinder 1, the cylinder 1 is fixedly connected to the motor 11, the output shaft of the motor 11 is fixedly connected to the driving bevel gear 12, each square shaft 15 is fixedly connected to a long shaft 14, each long shaft 14 is fixedly connected to a driven bevel gear 13, and each driven bevel gear 13 meshes with the driving bevel gear 12. By using the motor 11 to drive the gears and using bevel gear meshing, a set of square shafts 15 rotate synchronously when the motor 11 rotates.

[0031] The motor 11 is a GSK servo motor.

[0032] Each of the brackets 18 is fixedly connected to at least one guide rod 21, and each guide rod 21 passes through the corresponding lifting frame 22. By using guide rods 21 passing through the lifting frame 22, the stability of the lifting frame 22 in the height direction is increased.

[0034] The circular ring 4 is fixedly connected to a set of movable rods 5, and each movable rod 5 is fixedly connected to a wheel 6. The use of wheels 6 enables the transfer of this device.

[0035] Example 1: Each of the upper sliders 17 is fixedly connected to the corresponding round rod 9.

[0036] The working principle of the anti-deformation testing device for special equipment inspection provided by this utility model is as follows:

[0037] In the initial state, such as Figure 1 As shown, cylinders 30 are far apart from each other and are at the top of their travel in the height direction.

[0038] Move the device so that it is positioned at the center of the area formed by a set of cylinders 30.

[0039] The control motor 11 rotates, which drives the active bevel gear 12 to rotate. The active bevel gear 12 drives the driven bevel gear 13 to rotate. The driven bevel gear 13 drives the long shaft 14, square shaft 15, square hole shaft 25, and transmission bevel gear 24 to rotate. The transmission bevel gear 24 drives the power bevel gear 19 and screw 20 to rotate. The screw 20 drives the lifting frame 22 to move along the guide vertical rod 21. The lifting frame 22 drives the mounting vertical rod 23, hydraulic rod 26, pressure sensor 27, spring 28, round tube 29, and cylinder 30 to move, so that the cylinder 30 moves to a suitable height. The control hydraulic rod 26 extends, causing the cylinder 30 to press against the equipment, compressing the spring 28, and subjecting the pressure sensor 27 to a certain pressure value. The device is moved so that the pressure value of the pressure sensor 27 is approximately the same. The wheel 6 is locked, and the control hydraulic rod 26 extends, causing the cylinder 30 to press against the equipment, compressing the spring 28, thus achieving anti-deformation detection.

[0040] Example 2: The cylinder 1 is rotatably connected to the rotating ring 2. The rotating ring 2 is provided with a set of evenly distributed inclined grooves 3. Each upper slider 17 is fixedly connected to a circular block 16, and each circular block 16 is respectively set in the corresponding inclined groove 3. The ring 4 is rotatably connected to the electric push rod 7, and the push rod of the electric push rod 7 is rotatably connected to the rotating ring 2.

[0041] The electric push rod 7 is model BST-YF-B.

[0042] The working principle of the anti-deformation testing device for special equipment inspection provided by this utility model is as follows:

[0043] After the cylinder 30 descends to a suitable height, the electric push rod 7 is retracted. The electric push rod 7 drives the rotating ring 2 to rotate, and the rotating ring 2 drives the electric push rod 7 to swing. The rotating ring 2 drives the circular block 16 to move along the inclined groove 3. The circular block 16 drives the upper slider 17 to move along the circular rod 9 in the straight groove 8. The upper slider 17 drives the bracket 18 to move. The bracket 18 drives the square hole shaft 25 to move along the square shaft 15. The square hole shaft 25 drives the transmission bevel gear 24 to move. The bracket 18 drives the screw 20, the power bevel gear 19, the guide vertical rod 21, the lifting frame 22, the mounting vertical rod 23, the hydraulic rod 26, the pressure sensor 27, the spring 28, the circular tube 29, and the cylinder 30 to move, so that the cylinder 30 squeezes the equipment, so that the spring 28 is compressed, so that the pressure sensor 27 is subjected to a certain pressure value. The electric push rod 7 is closed, and the device is moved so that the pressure value of the pressure sensor 27 is approximately the same. The wheel 6 is locked. The hydraulic rod 26 is extended to compress the cylinder 30 into the equipment, thereby compressing the spring 28 and achieving deformation resistance detection.
