61 extrados of outer arcuate raising plate of semicircular plate is risen by the upward outside top of steel pipe recess 91, due to outside steel pipe recess 91
Side has pipe collar 7, and jacks the intrados of 61 extrados of outer arcuate raising plate of semicircular plate, pipe collar 7 as far as possible and in steel pipe 9
Outboard end contact surface coincide, close to unanimously, and there is 7 front and rear sides of pipe collar one fixed width to guarantee all to cover at steel pipe recess 91
It covers, playing in work prevents the convex position-limiting action of 9 recess of steel pipe, in this way, the outer arcuate raising plate 61 of jacking semicircular plate pushes up
Steel pipe 9 can restore to the original state as far as possible after rising, and degree of being held round meets subsequent installation needs；In practical operation, when needs keep electricity
Hydrodynamic pressure oil pump is exported in Thin type hydraulic jack 3 when pressure, that is, Thin type hydraulic jack 3 piston boit 31 temporarily not
Rise, operator issues the wireless open circuit signaling in the second road by wireless remote control device 4, and wireless receiving circuit 8 receives the second tunnel
After wireless open circuit signaling, electric hydraulic oil pump stops working, electric hydraulic oil pump temporarily not output hydraulic pressure oil enter it is slim hydraulic
In jack 3；After the recess 91 of steel pipe is modified, operator first closes electric hydaulic by wireless remote control device 4
Then oil pump issues the wireless open circuit signaling of the first via through wireless remote control device 4, it is wireless that wireless receiving circuit 8 receives the first via
After open circuit signaling, two power input power loss of mating solenoid valve DC of electric hydraulic oil pump, and then slim hydraulic jack can be made
Liquid oil inlet and oil return pipe, the electricity of oil inlet and oil return pipe of the hydraulic oil through Thin type hydraulic jack 3, hydraulic oil pipe 5, solenoid valve DC in top 3
The liquid back pipe of magnet valve DC passes back into the oilcan in electric hydraulic oil pump, while the plunger 31 of Thin type hydraulic jack 3 declines height
The 9 inner wall spacing distance of 61 falling head upper end of outer arcuate raising plate and steel pipe of degree, jacking semicircular plate, operator can incite somebody to action
Thin type hydraulic jack 3 is taken out out of steel pipe 9 completes all operationss process.In actual use, jacking semicircular plate 6, pipe collar 7 are each
It is spare with covering more, the jacking semicircular plate outer arc of a kind of mating different circular arc degrees of the steel pipe of every kind of different inner diameters, different length
Shape raising plate 61, pipe collar 7, ensure that in practical application, jack 61 extrados of outer arcuate raising plate of semicircular plate, pipe collar 7
Intrados coincide with outboard end contact surface in steel pipe 9 as far as possible；Same circular arc degree, different length are selected according to outer diameter of steel pipes using preceding
Jacking semicircular plate outer arcuate raising plate 61, pipe collar 7, installation jacking semicircular plate 6 when, directly original slim hydraulic thousand
Jin top force 31 and the connecting screw 62 of 32 lower end of cylinder, two outer arcuate raising plates 61 screw off, then two outer arcs of needs
The connecting screw 62 of shape raising plate 61 screws in spiral shell in Thin type hydraulic jack plunger 31 and 32 upper and lower side of cylinder middle part cylindrical groove
Line can.
