[0002] When performing hydraulic testing on workpieces such as blowout preventer accessories, the upper and lower flanges are usually manually clamped to the workpiece using fasteners such as bolts. Due to the large number of bolts and their large specifications, manual tightening is time-consuming and labor-intensive, and there are certain safety risks. At the same time, it is impossible to ensure that the bolts are clamped tightly, which greatly prolongs the overall time of the hydraulic testing. Utility Model Content

[0011] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0012] The utility model proposes a multifunctional pressure testing clamping device for blowout preventer accessories, including a base 1, in which a hydraulic top cylinder 4 and a pair of telescopic devices 10 are installed. Two pairs of columns 4 are installed on the upper wall of the base 1 and on both sides of the hydraulic top cylinder 4. The outer circumferential surfaces of the upper ends of the two pairs of columns 4 are threaded, and two pairs of turbine nuts 7 are threadedly connected to the upper ends of the two pairs of columns 4. An upper pressure block 6 is commonly installed on the two pairs of turbine nuts 7. A driving device 9 and a pair of worms 8 are installed on the upper wall of the upper pressure block 6. The two ends of the worm 8 are respectively engaged with the pair of turbine nuts 7. A loading platform 3 is installed in front of the base 1, and a support arm 2 is installed on the loading platform 3. The telescopic ends of a pair of telescopic devices 10 are connected to the support arm 2; the driving device 9 includes a motor and a reducer; the pair of telescopic devices 10 are a pair of telescopic hydraulic cylinders, and the support arm 2 is clamped on the telescopic ends of a pair of telescopic hydraulic cylinders; a positioning block 11 is installed at the center of the upper wall of the loading platform 3.

[0013] The multifunctional pressure test clamping device of the blowout preventer accessory needs to be connected to the external hydraulic system, control system, water pressure system, etc. when clamping and pressurizing the workpiece, and also needs to use the corresponding upper and lower flanges. When testing the workpiece, first install the lower flange on the loading platform 3. The positioning block 11 on the loading platform ensures the accurate position of the lower flange while preventing it from shifting to a certain extent. Then, the workpiece and the upper flange are installed on the upper flange in turn. A pair of telescopic hydraulic cylinders shortens and drives the loading platform 3 to slide until the loading platform 3 is located on the hydraulic top cylinder 4. At this time, the hydraulic top cylinder 4 is coaxial with the lower flange, and the driving device 9 drives a pair of turbine screws through the worm 8. The nut 7 rotates, thereby pressing the upper pressure block 6 downward to pre-tighten the upper flange. Sealing steel rings are installed at the contact points between the upper flange and the lower flange and the workpiece, and a high-pressure water channel is also provided on the lower flange. Since the support arm 2 is clamped on a pair of telescopic hydraulic cylinders, while ensuring that the loading platform 3 can slide back and forth without hindering its ascent, the hydraulic top cylinder 4 lifts the loading platform 3, the lower flange, and the workpiece together, at this time the entire clamping and clamping process is completed, and the workpiece is pressurized and tested through the high-pressure water channel. After the test is completed, the hydraulic top cylinder 4 falls to the lowest point, and a pair of telescopic hydraulic cylinders transports the loading platform 3 to its original position, removes the upper and lower flanges and the workpiece, and the entire process is completed.
