Specific embodiment
As shown in Figs. 1-5, a kind of transformation large-aperture pipe road nozzle school circular knitting machine, including school circular knitting machine ontology and it is rotatably arranged on school
Arcs 1 are respectively set in the school circle instrument of telescopic on circular knitting machine ontology, school circle instrument both ends.It is set at least one arcs 1 of prover
It sets and lengthens arc top cap 2.Lengthening arc top cap 2 is the plate that top is arc-shaped, and arc groove 21,21 bottom of arc groove is arranged in plate
It is arc-shaped and cooperates with arcs 1.Lengthening setting limiting device between arc top cap 2 and school circle instrument makes to lengthen arc top cap 2 and its
Position is constant between place arcs 1.Lengthen arc top cap 2 increase school circular knitting machine Calibration pipe maximum gauge, adapt to and diameter compared with
Big pipeline.School circular knitting machine in the present embodiment, most senior colonel's circular diameter is 1220 millimeters before, and present maximum can be to 1420 millimeters
Or 1620 millimeters.Slot bottom and arcs 1 the cooperation positioning of arc groove 21 lengthen the position of 2 up and down direction of arc top cap.
In the circle instrument embodiment 1 of school, prover can be hydraulic cylinder 3, and 31 end of piston rod of hydraulic cylinder 3 and bottom end are respectively set
Arcs 1,1 thickness of arcs are less than 31 diameter of piston rod.Arc top cap 2 is lengthened to be arranged in the arcs 1 of 31 side of piston rod.It lengthens
Setting U-lag 22 position for making the positioning of piston rod 31 lengthen arc top cap 2 corresponding with 31 position of piston rod among 2 bottom of arc top cap
It sets.U-lag 22 first can interfere between arc top cap 2 and piston rod 31 to avoid lengthening.Second because 1 thickness of arcs is small
In 31 diameter of piston rod, its left and right directions position is defined when piston rod 31 is located in U-lag 22, to make to lengthen arc top cap
The positioning of 2 left and right directions.Here left and right, front-rear direction are the directions in Figure of description.In this way lengthen arc top cap 2 it is upper,
The position of left and right has all determined, as long as lengthening the top half that arc top cap 2 is always positioned at pipeline in 3 rotation process of hydraulic cylinder,
Lengthen arc top cap 2 would not be detached from, and mount and dismount it is very simple, it is only necessary to put or remove from arcs 1 plus
Long arc shape top cap 2.
In the circle instrument embodiment 2 of school, difference from example 1 is that: piston rod 31 is arranged in 3 both ends of hydraulic cylinder, each
Arcs 1 are arranged in tailpiece of the piston rod 31, and setting lengthens arc top cap 2 at least one arcs 1.Two piston rods 31, each piston rod
The benefit that all setting lengthens arc top cap 2 on 31 is that the rotation of hydraulic cylinder 3 is more convenient, can not have to first shrink piston after accurate positioning
Bar 31.
1 upper surface of arcs be it is arc-shaped, lower end surface is plane；It lengthens after arc top cap 2 is mounted in arcs 1 and is located at arcs
Two positioning pins 4 or bolt is arranged in position below 1 lower end surface, lengthens 2 corresponding position of arc top cap and pin hole 23 is arranged.Positioning
The position of pin 4 or bolt closely 1 lower end surface of arcs.The position for lengthening 2 lower section of arc top cap so also positions.School circle instrument rotation
During 180 degree, it will not fall off and accurate positioning.Installing and dismounting is very convenient.
The left and right sides of U-lag 22 can be arc-shaped to be cooperated with piston rod 31.It is positioned such that effect is more preferable, and will not
Damage 31 surface of piston rod.
School circular knitting machine further includes that can push or the trolley 5 of electric walking, and hydraulic cylinder 3 passes through the liquid being arranged on vehicle frame 6
Rotation motor 7 is pressed to drive rotation, design hydraulic station 8 provides power to hydraulic rotating motor and hydraulic cylinder on vehicle frame.It is set on trolley
Set the movement of controller control mechanism.
When it is implemented, being placed into arc top cap 2 is lengthened in arcs 1,21 bottom of arc groove is made to be placed into the upper of arcs 1
On end face, piston rod 31 is located in U-type groove 22 at this time, installs positioning pin 4 or bolt.Trolley 5 is pushed to arrive to school round pipe
Position, hydraulic cylinder 3 reach nozzle in, controller control hydraulic station 8 to hydraulic cylinder 3 provide power, make piston rod 31 elongation until
Predetermined length, the arcs 1 or lengthening arc top cap 2 for lengthening arc top cap 2 and the other end at this time hold out against inner wall of the pipe and make pipeline
School circle.The rotation of hydraulic cylinder 3 is driven to make entire pipeline nozzle school circle by hydraulic rotating motor 7.
