A pressure-bearing detection device for special equipment pressure pipelines includes a bottom plate 1. Support legs 2 are bolted and fixed at the four corners of the bottom of the bottom plate 1. A roller 3 is bolted and fixed on one side of the top of the bottom plate 1. Fixed rings 4 are provided on both sides of the top of the bottom plate 1. A positioning frame 5 is bolted and fixed on one side of the top of the bottom plate 1. An electric telescopic rod 6 is bolted and fixed at the bottom of the positioning frame 5. A detection ring 7 is welded and fixed at the bottom of the electric telescopic rod 6. A pressure sensor 8 is electrically connected to the top of the detection ring 7. A clamping mechanism 9 is arranged on the top of the bottom plate 1. The clamping mechanism 9 facilitates clamping and stabilizing during the detection of the pressure pipeline. Through holes 10 are opened on both sides of the surface of the bottom plate 1. Positioning blocks 11 are bolted and fixed at the four corners of the bottom of the bottom plate 1.

[0022] In the specific implementation process, as Figure 2 and Figure 3 shown, the clamping mechanism 9 includes a double-shaft motor 91. The top of the double-shaft motor 91 is bolted and fixed to the bottom plate 1. A lead screw 92 is key-connected to the output end of the double-shaft motor 91. A nut 93 is threadedly connected to the surface of the lead screw 92. A positioning rod 94 is welded and fixed to the top of the nut 93. The tops of the positioning rods 94 all penetrate into the inner cavity of the through hole 10 and are bolted and fixed to the fixed ring 4;

[0023] When it is necessary to clamp the pressure pipeline for measurement, first turn on the double-shaft motor 91. Drive the lead screw 92 to rotate through the output end of the double-shaft motor 91. While the lead screw 92 rotates, drive the nut 93 to move relatively. While the nut 93 moves, drive the positioning rod 94 to move in the inner cavity of the through hole 10. While the positioning rod 94 moves, drive the fixed ring 4 to move relatively, so as to effectively clamp and fix the pressure pipeline during detection.

[0024] Refer to Figure 3 shown, support blocks 12 are connected to the opposite sides of the two lead screws 92 through bearings. The tops of the support blocks 12 are bolted and fixed to the bottom plate 1;

[0025] The connection between the support block 12 and the bottom plate 1 plays an effect of limiting and supporting the lead screw 92.

[0026] Refer to Figure 3 shown, sliding sleeves 13 are bolted and fixed on both sides of the nut 93. The inner cavities of the sliding sleeves 13 are all slidably sleeved on sliding rods 14. Both sides of the sliding rods 14 are bolted and fixed to the positioning blocks 11;

[0027] The connection between the sliding sleeve 13 and the sliding rod 14 plays an effect of assisting the movement of the nut 93 during movement.

[0028] Refer to Figure 2 and Figure 3 shown, reinforcing blocks 15 are bolted and fixed on both sides of the positioning rod 94. One sides of the reinforcing blocks 15 are bolted and fixed to the fixed ring 4;

[0029] The connection between the reinforcing block 15 and the positioning rod 94 has the effect of fixing and positioning the fixing ring 4.

[0030] Reference Figure 2 As shown, support rods 16 are fixedly welded to the bottoms of the two fixing rings 4, and the bottoms of the support rods 16 are bolted to the positioning rods 94;

[0031] The connection between the support rod 16 and the positioning rod 94 has the effect of reinforcing and supporting the fixing ring 4.

[0032] The working principle of a pressure-bearing detection device for special equipment pressure pipelines provided by the present utility model is as follows:

[0033] When in use, first move the device to a suitable position. Then, sequentially push the pressure pipeline to be detected from the surface of the roller 3 into the inner cavity of the fixing ring 4. Subsequently, turn on the double-shaft motor 91. The output end of the double-shaft motor 91 drives the lead screw 92 to rotate. While the lead screw 92 rotates, it drives the nut sleeve 93 to move relatively. Then, while the nut sleeve 93 moves, it drives the sliding sleeve 13 to move assistingly on the surface of the sliding rod 14. Subsequently, while the nut sleeve 93 moves, it drives the positioning rod 94 to move in the inner cavity of the through hole 10. While the positioning rod 94 moves, it drives the fixing ring 4 to move relatively, so as to effectively clamp and fix the pressure pipeline during detection. Finally, when detecting the clamped and fixed pressure pipeline, first turn on the electric telescopic rod 6. The telescopic movement of the electric telescopic rod 6 drives the detection ring 7 to move downward to the surface of the pressure pipeline. Then, while the detection ring 7 moves, it drives the pressure sensor 8 to detect. The detected data appears on the instrument of the pressure sensor 8 in sequence. The pressure sensor 8 can accurately measure the pressure change inside the pipeline for the staff to view.

[0034] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
