The feeding side for suppressing position is additionally provided with tapping turnover panel 17, and the one end for turnover panel of tapping connects hinged shaft, and the other end and tapping are dynamic
The piston end for making cylinder is connected.Tapping turnover panel 17 effect be when steel pipe suppress position complete suppress after, push steel pipe to delay
Deposit area's rolling.
In embodiment, Fig. 7 is seen, the structure for waiting material turnover panel 15, caching turnover panel 16, tapping turnover panel 17 and stop turnover panel 31 is homogeneous
It together, include hinged shaft 23, turnover panel 24, actuating cylinder 25, turnover panel 24 is hinged with ground fixture by hinged shaft, the work of actuating cylinder 25
Plug end is connected with the back of end plate, and when actuating cylinder 25 acts, turnover panel 24 can be erected or is laid flat, and realizes the limitation to steel pipe
Or it lets pass.
See Fig. 8, suppresses and set on position there are two V-arrangement hydraulic bracket 14, two V-arrangement hydraulic bracket one is located at tube head seal receptacle
12 sides, another is located at 13 side of pipe tail seal receptacle, the V-arrangement liquid of the V-arrangement hydraulic bracket of pipe tail seal receptacle side than tube head seal receptacle side
High 10 ~ the 20mm of pressure bracket, structure are made of the V-arrangement bracket 32 on top and the hydraulic cylinder 33 of bottom, the lifting of V-arrangement bracket 32
It is controlled to adjust by hydraulic cylinder 33.
The operating method of the universal steel pipe bulge test device of the present invention, specific steps are as follows:
1) steel pipe 21 to be suppressed is hung by crane is sent to the area Hou Liao, waits material turnover panel 15 and acts, the area Shi Houliao steel pipe to be suppressed is along charging
Siding track is rolled to suppressing position；
2) it suppresses V-arrangement hydraulic bracket 14 on position to rise, steel pipe be held up, steel pipe both ends are close with tube head seal receptacle 12 and pipe tail respectively
The sealing ring 8 sealed on seat 13 is in place, and hydraulic cylinder 5 stretches out, and makes tube head seal receptacle 12 and pipe tail seal receptacle 13 steel pipe 21 to be suppressed
Firmly clamp；
3) before to the water filling of 4 pipe network of hydraulic pressure system, drain valve 10 is closed, exhaust valve 22 is opened, the injecting process slowly boosts, boosting speed
Rate should be controlled to be no more than 0.1MPa/ minute per minute, observe when water filling steel pipe seam whether leak；
When the design work pressure wait suppress steel pipe 21 is equal to or less than 1.0MPa, water pressure test for strength pressure should be design work
1.5 times for making pressure, and not lower than 1.4MPa；When system design work pressure is greater than 1.0MPa, water pressure test for strength pressure
Power should be the operating pressure and add 0.4MPa；
4) after hydraulic pressure system 4 reaches test pressure, 30 ~ 45min of pressure stabilizing, pipe network answers No leakage, without deformation, and pressure drop is not answered
Greater than 0.05MPa, it is considered as 21 No leakage of steel pipe to be suppressed；
5) drain valve 22 on tube head seal receptacle 12 is opened, the water in the steel pipe for having beaten pressure is all discharged；
6) hydraulic cylinder 5 retracts, and tube head seal receptacle 12 and pipe tail seal receptacle 13 respectively retreat and steel pipe discharged, and tapping turnover panel 17 is dynamic
To make, pushes the steel pipe for having beaten pressure to the siding track 3 that discharges, steel pipe is rolled to buffer area along discharging siding track, and caching turnover panel 16 acts,
Steel pipe is set to rest on buffer area, until crane handling is walked.
When the water pressure test, environment temperature is lower than 5 DEG C, hydraulic pressure system 4 need to do antifreezing measures using heating device.
Hydraulic pressure system carries out that it is tight hydraulic pressure should be carried out after water pressure test for strength and pipe network wash are qualified before water filling suppresses test
Tightness test, it is desirable that test pressure should be design work pressure, and No leakage is answered in pressure stabilizing for 24 hours.
Before the present invention suppresses test, first the pipe network to hydraulic pressure system 4 and valve do water pressure test for strength to need and air pressure is tight
Property test, to guarantee the accurate of test result, its step are as follows:
1) water pressure test for strength pressure is 1.5 times of design of pipe networks operating pressure；Air pressure leak test pressure is design work
Pressure；
2) when carrying out water pressure test for strength, water temperature should be not less than 5 DEG C, and pressure stabilizing is no less than 1min after reaching test pressure, and range estimation is answered
Without deformation；
3) air pressure leak test should carry out after water pressure test for strength, and air or nitrogen can be used in test(ing) medium, test appropriate to the occasion

3) before to the water filling of hydraulic pressure system pipe network, drain valve is closed, exhaust valve is opened, the injecting process slowly boosts, and rate of pressure rise is answered
Control is no more than 0.1MPa/ minutes per minute, when water filling observe wait suppress the weld seam on steel pipe whether leak；
When the design work pressure wait suppress steel pipe is equal to or less than 1.0MPa, water pressure test for strength pressure should be design work
1.5 times of pressure, and not lower than 1.4MPa；When system design work pressure is greater than 1.0MPa, water pressure test for strength pressure
It should be the operating pressure and add 0.4MPa；
4) after hydraulic pressure system reaches test pressure, 30 ~ 45min of pressure stabilizing, pipe network answers No leakage, without deformation, and pressure drop is not answered
Greater than 0.05MPa, it is considered as steel pipe No leakage to be suppressed；
5) drain valve on tube head seal receptacle is opened, will be all discharged wait suppress the water in steel pipe；
6) hydraulic cylinder retracts, and tube head seal receptacle and pipe tail seal receptacle respectively retreat and steel pipe to be suppressed discharged, tapping turnover panel movement,
Push the steel pipe after suppressing to the siding track that discharges, steel pipe is rolled to buffer area along discharging siding track, and caching turnover panel movement makes steel pipe
Buffer area is rested on, until crane handling is walked.
9. the operating method of universal steel pipe bulge test device according to claim 8, which is characterized in that the hydraulic pressure
When environment temperature is lower than 5 DEG C when test, hydraulic pressure system does antifreezing measures using heating device.
10. the operating method of universal steel pipe bulge test device according to claim 8, which is characterized in that the water
Pressure system carries out that hydraulic pressure leak test should be carried out after water pressure test for strength and pipe network wash are qualified before water filling suppresses test,
It is required that test pressure should be design work pressure, No leakage is answered in pressure stabilizing for 24 hours.
