[0038] Inside the lifting frame 310, a connecting frame 311 for further supporting the lifting frame 310 is fixedly installed. A ring body is provided in the middle of the connecting frame 311, through which the pipe body of the instrument can pass for detection, making the connection between the two sides of the lifting frame 310 more stable and preventing the lifting frame 310 from deforming and expanding to both sides when the hydraulic clamping part 340 extends.

[0039] The rotating unit 200 includes a rotating table 210 movably installed at the upper end of the inspection table 100 for supporting the parts at the upper end. At the upper end of the rotating table 210, an adjusting screw 220 is movably installed for lifting and adjusting the positioning unit 300 installed at the upper end of the rotating table 210. The lifting frame 310 is sleeved on the upper end of the adjusting screw 220 and is thread-matched with the lifting frame 310. The lower end of the rotating table 210 is movably installed inside the inspection table 100 through a bearing and is connected for power supply through a conductive slip ring. The detection head 120 is installed through the through groove 211 opened in the middle of the rotating table 210.

A threaded part 130 for connecting and fixing the detection head 120 is provided on the outside of the detection head 120, which can be thread-connected and fastened and sealed with the lower end of the instrument.

[0041] After the detection head 120 is fixed, the driving device can be used to drive the second runner 214 to rotate, and then drive the first runner 212 to rotate through the first transmission belt 213, and then drive the rotating table 210 installed at the upper end to rotate, driving the internally fixed instrument to rotate, making the pipe body at its lower end thread-connected with the threaded part 130, and further making the connection between the instrument and the detection head 120 more stable. It can be adapted to some instrument pipe bodies with internal threads, facilitating detection after connection.

[0042] A display 110 for displaying and observing the detection data is provided at the upper end of the inspection table 100. The supply state of the air supply and pressure supply device can be observed through the display 110, facilitating the adjustment of the detection data of the instrument.

When the telescopic claws 323 expand and place the instrument, the arc-shaped rack 331 arranged at the lower end temporarily fixes the instrument, eliminating the need for manual holding. After the instrument is supported, it is convenient for the telescopic claws 323 to contract for clamping. Moreover, the elongation of the telescopic screw 332 can be adjusted by adjusting the rotating nut 334, and the position of the arc-shaped rack 331 can be adjusted to facilitate adapting to instruments of different thicknesses.

[0044] A rotating seat 221 for supporting and installing the adjusting screw 220 fixedly installed at the upper end is fixedly installed at the lower end of the adjusting screw 220, and a third runner fixedly arranged at the upper end of the rotating seat 221 is provided. The rotating seat 221 is driven through the second transmission belt 222 sleeved at the upper end and is driven through the fourth runner 223 installed on one side. The fourth runner 223 is connected to the output end of the stepping motor, and a positioning wheel 224 for guiding and limiting the second transmission belt 222 is arranged on one side of the fourth runner 223. Both sides of the positioning wheel 224 are movably installed in the inner cavity of the rotating table 210 through bearings. After the instrument is fixed, the driving device can be used to drive the fourth runner 223 to rotate, and then drive the rotating seat 221 to rotate through the second transmission belt 222, and then drive the adjusting screw 220 fixedly installed at the upper end to rotate. Then, the lifting rack 310 installed at the upper end moves downward, and the fixed instrument can be driven to move stably downward, so that the lower end pipe body of the instrument is tightly connected to the detection head 120, facilitating the detection of the instrument performance.

[0045] Working principle of a continuous instrument detection and calibration device: When detecting the instrument, the instrument can be placed in the middle of the clamping unit 320. Then, it can be moved and tightened through the cooperation of the guide rod 322 and the track cylinder part 324, and then drive the externally movably installed telescopic claws 323 to move, so as to clamp and center the internal instrument. Then, drive the instrument to press down so that the lower end of the instrument is connected to the detection head 120, and then conduct a pressure test on it, facilitating the detection of the instrument. At the same time, contracting the telescopic claws 323 for clamping and fixing can effectively center the instrument and make it more convenient to connect with the detection head 120.
