Description

Technical Field

[0001] The invention relates to the technical field of flange strength detection, and in particular to a titanium flange connection strength detection device. Background Art

[0002] Flanges are widely used in actual pipeline connection and other work. Threaded flanges are a common type of flanges in actual flanges. The threads set on the inside can facilitate the connection of pipelines. In the continuous production of modern industry, flanges are prone to leakage due to factors such as medium corrosion, erosion, temperature, pressure, vibration, etc., especially some threaded flanges with larger diameters. Their service life is closely related to the thread strength of the flange. At present, titanium flanges are widely used due to their good corrosion resistance. The current titanium flange connection strength detection device is not convenient for automatic detection of the compressive strength of the edge of the flange bolt hole. Most of them rely on manual visual observation after pressure is applied, which is not efficient and accurate. At the same time, in the actual threaded flange strength test, the strength quality of its internal thread is not convenient for digital display and intuitive detection, which is easy to cause missed detection. The detection head of the threaded flange is greatly worn, which is not convenient for compensating the wear gap. Summary of the invention

The staff can compare the standard value.

[0027] The working principle of this embodiment is as follows: first, the titanium flange is placed on the detection mounting plate 101. At this time, the bolt hole of the flange is inserted into the plug-in positioning column 2021, and the four indentation hydraulic cylinders 102 drive the pressing platform 202 to press down to achieve pressurized titanium flange. As the extrusion time goes by, the indentation hydraulic cylinder 102 controls the pressing platform 202 to rise. When it is separated from the end face of the titanium flange, the telescopic adapter sliding column 301 is pulled to move to the inside of the positioning ring 201 under the pull of the internal tension spring 303. At the same time, the downward tension spring 3021 pulls the plug-in adapter inclined block 30 5 is attached to the end face of the flange in real time, and the front end of the plug-in adapter bevel block 305 can be inserted into the bottom of the pressing platform 202 in conjunction with the bevel structure at the top of the plug-in adapter bevel block 305. At this time, if there is an indentation on the titanium flange below the pressing platform 202, the power-connecting spring piece 306 can fit at the bottom of the indentation under the elastic action. At this time, the power-connecting spring piece 306 will move downward and separate from the fixed power-connecting block 307. At this time, the alarm light 304 will be powered off to remind the staff that if the pressing platform 202 is driven down again to fit the titanium flange, the pressing platform 202 can By squeezing and plugging the inclined surface of the adapter bevel block 305, the plug-in adapter bevel block 305 will move inward under squeezing, and the plug-in adapter bevel block 305 will not get stuck and block the pressing table 202, and there is no need for staff to adjust and control; start the traction hydraulic cylinder 404 to control the telescopic column 403 to drive the lifting cylinder 501 to descend and insert the threaded flange, and the gear on the output shaft of the driving motor 402 can drive the meshing teeth on the outer side of the rotating cylinder 401 to control the rotation of the rotating cylinder 401, so as to realize the control of the lifting cylinder 501 to rotate and drive the threaded plug-in plate 601 to rise and squeeze the screw The threads on the inner side of the threaded flange and the rotating threaded plug-in plate 601 adjust the detection position; the lifting cylinder 501 rotates and inserts the threaded flange, and a row of threaded plug-in plates 601 are also driven to be screwed into the interval of the threads on the inner side of the threaded flange. As the use cycle of a row of threaded plug-in plates 601 increases, the lifting hydraulic cylinder 504 can be used to drive the extrusion bevel column 503 to move upward to squeeze the outward extrusion plate 502. At this time, the outward extrusion plate 502 can push a row of threaded plug-in plates 601 to expand outward to adapt to the threads at the same time, thereby reducing the gap;When a row of threaded plug-in plates 601 are inserted into the threaded intervals on the inner side of the threaded flange, as the traction hydraulic cylinder 404 controls a row of threaded plug-in plates 601 to move up and pull the threads of the threaded flange, the lifting cylinder 501 can be controlled to stop after rotating a certain angle. Note that the initial positions of the threaded plug-in plates 601 on the inner side of the threaded flange should be consistent to ensure that the subsequent comparison with the standard values ​​is accurate. At this time, the downward pressure adapter plate 701 and the connecting spring 702 are also driven to rotate, and the connecting spring 702 will squeeze the downward pressure adapter plate 701, so that the downward pressure head 70 4 is attached to the end face of the threaded flange. According to the predetermined standard value, once the thread inside the threaded flange is squeezed and deformed by the threaded plug-in plate 601, the threaded plug-in plate 601 will move upward, and the lifting cylinder 501 will also move together. At this time, the stroke of the connecting spring 702 increases, and its elastic force naturally decreases. The pressure sensor 703 can detect the pressure in real time, and the digital display is displayed on the display 104. The staff can compare the standard value. Based on this principle, the lifting cylinder 501 can be controlled to rotate and gradually detect different radial positions around the threaded flange. ;
