Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, with reference to embodiments and its attached drawing is to this hair
It is bright to be described further.
Embodiment
For the measuring device of seamless steel tube for ship seamless interfacing, wherein a steel pipe is fixing pipe for definition, and another steel pipe is movable
Pipe, in fixing pipe, movable tube end, device 1 is fixed in installation one with one heart, is provided with signal processing on the fixation device of fixing pipe
Device 2, and it is provided with rotatable laser emitter 3 at fixed device center, it is adjustable with the angle of the fixed device
Section, emitted laser can become perpendicular to fixing pipe fixation device surface to being parallel within the scope of fixing pipe fixation device surface
Change, disk 6, angle measurement plate 7, measurement pedestal 8 are provided at the fixation device center of movable pipe；The angle measurement plate 7
Selected from a series of different size of square plates, it can be perpendicularly fixed on measurement pedestal 8, measure and set at 8 upper surface center of pedestal
Laser receiver is set, and measures pedestal 8 and 6 the center point of disk is rotatably installed on by shafting, disk 6 is fixed on movable pipe
Fixed device center.The signal processing apparatus 2 is equipped with range display 4, for show the front end of laser emitter 3 away from
Angle with a distance from laser receiver between laser emitter 3 and fixed pipe fixing device.
The present embodiment be used for seamless steel tube for ship seamless interfacing when the measuring device course of work include:
When two port of steel pipe plane included angles are no more than 45 °, adjustment laser emitter angle makes transmitting laser vertical
In fixing pipe fixation device surface, then slowly rotating clip angular measurement plate 7, makes the one side of angle measurement plate 7 with the track of laser
It being overlapped, laser can be measured with angle α (as shown in Figure 3) formed by 7 bottom edge of angle measurement plate in angle measurement plate, then and two
The angle of port of steel pipe plane is (90- α) degree, then the bending angle of connecting tube bend pipe is (90+ α) degree.When two port of steel pipe
When plane included angle is more than 45 °, adjustment laser emitter 3 launches the laser for being parallel to fixing pipe fixation device surface, at this point, turning
Dynamic angle measurement plate 7, is overlapped the one side of angle measurement plate 7 with the track of laser, formed by laser and 7 bottom edge of angle measurement plate
Angle α can be measured in angle measurement plate, then the angle of two steel tube end part planes is α degree, the bending angle of connecting tube bend pipe
Degree is that (180- α) is spent.
Thereafter, angle measurement plate 7 is removed, the launch angle of laser emitter is adjusted, beats laser in measurement 8 center of circle of pedestal
On neighbouring laser receiver, the registration of range display 4: distance l, the i.e. corresponding maximum chord length of connecting tube bend pipe is read.
When bending angle is that (90+ α) is spent or (180- α) is spent, when chord length is l, can find out its corresponding radius of curvature is R, i.e. bend pipe pair
The maximum radius of curvature answered, as long as selection meets the minimum profile curvature radius r that bend standards require and are not more than R.Such as Fig. 4 institute
Show, restriction of the bending radius of bend pipe by the spatial position between elbow curvature standard, fixing pipe and movable pipe, therefore uses full
Sufficient bend standards require and are not more than the minimum profile curvature radius r of R, because fixing pipe and movably managing coplanar its intersection point afterwards away from two-port
The distance of plane be not necessarily it is equal, when unequal, select elbow radius be less than R, meet bend pipe so directly selecting
The minimum profile curvature radius r of standard, both ends are connected with straight tube, and r is centainly not more than R, and otherwise the position can not install connecting tube.
Connecting tube consists of two parts: bending angle is that (90+ α) is spent or (180- α) degree, bending radius are the bent portion of r
Point and two side length of bend pipe be no more than the straight-tube portion of l.
In actual mechanical process, by connecting tube and fixing pipe by flanged joint, connecting tube is held level with both hands close to the one of movable pipe
In movable pipe, at this point, moving in parallel movable pipe, the connection of connecting tube Yu movable pipe can be realized in row.When straight-tube portion is too long,
Cut away redundance.
