Embodiment
Referring to Fig. 1,2, a kind of drawing machine of peeling off of testing steel pipe 3PE external anticorrosive coating peeling intensity, include housing 1, housing 1 bottom left is provided with road wheel 2, housing 1 left side is also connected with support wheel 3 by connecting rod, in housing 1, be provided with and peel off drum 4, peel off drum 4 and be connected with clamper 6 by tension pole 5, the lower end of clamper 6 is connected with steel tube surface and levers up to be stripped 7 of next PE, peeling off above clamper 6, on drum 4, be also provided with force cell 8, mainboard 9 in housing 1 by WIFI be connected with computer 10, printer 11 and electric battery 12 are contained on device housings.
The quantity of described support wheel has two groups at least.
Described steel tube surface levers up to be stripped 7 of the PE that come between two groups of support wheels 3.
By panel computer, by WIFI remote control, peel off drawing machine and realize action.First will peel off drawing machine is placed in directly over steel pipe to be detected with reference to shown in Fig. 1, during work, peeling off drawing machine at the uniform velocity walks along the direction of arrow at 3PE outer surface of steel tube circumferencial direction, peel off at the uniform velocity rotation of drum, utilize tension pole and clamper on it to drive to be stripped 7 edge of PE that steel tube surface levers up to be stripped from perpendicular to steel tube surface direction, stripping process is divided into pre-tensioner and normally peels off two stages, in this process, force cell feeds back real-time peeling force size and is uploaded to panel computer, software on panel computer calculates a maximal force to recording power value according to every 2 minutes (corresponding strip length 20mm), minimum force value and mean force value are also drawn real-time testing curve and data recording form.Peel off drawing machine and stop having moved test process when limiting position, setting-up time or pressing start button the 2nd time reaching.After completing, user can printing test result.Also can query history test record.
The present invention can implement in the steps below:
20 ± 5 ℃ of probe temperatures.First anticorrosive coat to be scratched to width along hoop be 20mm～50mm, more than long 10cm rectangular, while scratching, should draw anticorrosive coat, and lever up one end and be about 30mm, and PE is to be stripped, with clamper 6, clips.Peeling off drawing machine, be placed in steel tube surface (along the direction of circumferentially walking), position will conveniently hang over clamper to peel off on bulging tension pole, the position of to be stripped of PE that drawing machine and steel tube surface lever up is peeled off in adjustment to be stripped of PE, perpendicular to steel tube surface, peels off drum with set lever 13 lockings of peeling off drawing machine side.Open and peel off drawing machine power supply and dull and stereotyped computer power, after starting test procedure, input customer parameter, referring to Fig. 3, click SPEED button and carry out pre-tensioner operation, now peel off drum, with fast speed forward rotation, PE bar is carried out to tensioning in advance (referring to direction shown in the thick arrow of accompanying drawing 1), then user clicks START button and starts to enter official testing process, in this process, shows in real time power value and the relation curve of time and the maximal force in every 2 minutes, minimum force value and mean force value while peeling off.Test process presses from user that START button starts till the work period setting reaches or user presses START button again.User clicks and enters Print label printing test result.When equipment is not worked, can click QUERY button by pipe number or test result or the printing in the past of date interval query.
