Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a special equipment testing device, such as... Figure 1 and Figure 2As shown, the special equipment testing device includes a testing frame 1 with a testing cavity. Protective boxes 2 are hinged to both sides of the testing frame 1 corresponding to the testing cavity. An observation cavity is located on the side of the protective box 2 away from the testing frame 1, and an observation window is embedded in the observation cavity. Through the observation window, the interior of the testing cavity can be easily and effectively observed during operation. A locking block 21 is fixed to the end of the protective box 2 away from the hinge. A mounting block 5 is symmetrically protruding and fixed to the end of the testing frame 1 away from the protective box 2. A snap-fit ​​block 6 is inserted into the mounting block 5. The snap-fit ​​block 6 is inverted U-shaped, and the locking block 21 has an insertion hole for the snap-fit ​​block 6. A support cavity is located at the bottom of the testing frame 1, and diagonal rods are fixed obliquely and alternately within the support cavity. A base protrudes from the bottom of the testing frame 1.

[0027] By installing protective boxes 2 on both sides of the test frame 1, auxiliary protection can be provided for both sides of the test frame 1 during pressure testing, so as to avoid situations such as the pressure pipeline 15 collapsing and causing injury to surrounding personnel.

[0028] Reference Figure 2 , Figure 3 and Figure 4 As shown, a protruding strip 7 is horizontally fixed at the bottom of the detection chamber. The vertical cross-section of the protruding strip 7 is T-shaped. A clamping cavity is opened at the top of the protruding strip 7. An auxiliary clamping assembly 8 is installed in the clamping cavity. The clamping assembly 8 provides auxiliary clamping and fixing of the pressure pipeline 15. A hydraulic rod 3 is installed at the inner top of the detection frame 1. A push block 4 is fixed at the extended end of the hydraulic rod 3. A pressure sensor for testing the downward pressure can be installed at the bottom of the push block 4. The pressure sensor model is MPX5700D. This model can be used but is not limited to. The clamping assembly 8 includes a bidirectional screw 9 rotatably disposed in the clamping cavity. A connecting block 14 is symmetrically protruding from the top of the bidirectional screw 9. The connecting block 14 has a snap-fit ​​groove for snapping and fixing the protruding strip 7. A sleeve block 141 is protruding from the bottom of the connecting block 14. The sleeve block 141 is sleeved and installed on the bidirectional screw 9. The bidirectional screw 9 and the sleeve block 141 are threaded together. Clamping blocks 11 are fixed at both ends of the connecting block 14. A clamping ring 12 is provided on one side of the clamping block 11. A rotary motor 10 for assisting the rotation of the bidirectional screw 9 is installed on the outer side of the detection frame 1.

[0029] By using the clamping assembly 8, the rotating motor 10 is started, which drives the bidirectional screw 9 to rotate as a whole. The bidirectional screw 9 is threadedly engaged with the sleeve block 141, thereby causing the sleeve block 141 to move as a whole. During the movement of the sleeve block 141, the connecting block 14 moves, and during the movement of the connecting block 14, the clamping block 11 moves as a whole. During the movement of the clamping block 11, the pressure pipeline 15 is subjected to auxiliary clamping treatment, which can ensure that the working pressure pipeline 15 can be stably fixed.

[0030] The clamping ring 12 has a protruding insertion block 121 on its outer side, and an insertion groove 111 is provided on the inner side of the clamping block 11. The insertion groove 111 and the insertion block 121 are inserted into each other. The insertion block 121 has a mounting hole. A positioning bolt 13 is threaded on the outer side of the clamping block 11. The mounting hole and the positioning bolt 13 are inserted into each other.

[0031] By using the clamping assembly 8 installed on the protruding strip 7 and the detachable and replaceable clamping ring 12 on the clamping block 11, the clamping ring 12 of the corresponding size can be replaced during operation. The insertion block 121 is then inserted into the insertion slot 111, and the positioning bolt 13 is rotated. The clamping block 11 and the positioning bolt 13 are threaded together, so that the positioning bolt 13 is inserted into the mounting hole, thereby completing the overall installation of the clamping ring 12. This ensures that the pressure pipe 15 of different sizes can be fixed on the corresponding clamping assembly 8 when fixing, thus completing the overall positioning and fastening of the pressure pipe 15 and ensuring that subsequent work can proceed smoothly.

[0032] Working principle:

[0033] During operation, before installing the pressure pipeline 15, replace the clamping ring 12 with one of the corresponding size, insert the plug block 121 into the plug groove 111, rotate the positioning bolt 13, and the clamping block 11 and the positioning bolt 13 will be threaded together, so that the positioning bolt 13 can be inserted into the mounting hole, thereby completing the overall installation of the clamping ring 12.

[0034] The pressure pipe 15 is placed on the clamping ring 12 between the two clamping blocks 11. The rotating motor 10 is started, and the rotating motor 10 drives the bidirectional screw 9 to rotate as a whole. The bidirectional screw 9 is threadedly engaged with the sleeve block 141, thereby causing the sleeve block 141 to move as a whole. During the movement of the sleeve block 141, the connecting block 14 moves, and during the movement of the connecting block 14, the clamping block 11 moves as a whole. During the movement of the clamping block 11, the pressure pipe 15 is subjected to auxiliary clamping treatment.

[0035] After clamping, the protective box 2 is placed on the side of the testing frame 1, and the snap-fit ​​block 6 is inserted into the insertion hole of the snap-fit ​​block 21, thereby completing the overall fixing of the protective box 2. The hydraulic rod 3 is activated, and during the extension of the hydraulic rod 3, the pushing block 4 is moved as a whole, and the top of the pressure pipe 15 is subjected to auxiliary pressing treatment, thereby effectively testing the overall pressure resistance performance of the pressure pipe 15.
