The stability for further improving the precision of measurement and using.
In the present embodiment, the side of bent angle Measuring plate is located at curved close to outer corner measurement disk side, corner fastening bolt 231
Angular measurement disk is in the radial direction, it is to be understood that the angle of the angular measurement disk that can be gone for a stroll by corner trip bolt rotation obtains
To the bent angle of ship school pipe, the precision of measurement is helped to improve.
Specifically, the outer bar 11 and interior bar 12 in the present embodiment are stainless steel or aluminium alloy rod, make linear measure longimetry group
Part 1 is more robust, improves the service life of device.
The quantity of linear measure longimetry component 1 and angle measure component 2 is by several groups, linear measure longimetry component 1 and another length
Measurement assembly 1 is connected by angle measure component 2, and interior bar 12 and the rod set 22 of another linear measure longimetry component 1 are fixed by socket in reality
In the application of border, the length of ship school pipe is measured by the linear measure longimetry component 1 with scale mark, in the bending place of ship school pipe
The length that another linear measure longimetry component 1 continues the pipe difference segmentation of measurement ship school is connected by angle measure component 2.
Include five groups of length measurement assemblies 1 and four groups of angle measure components 2 in the present embodiment with reference to figure 5~6, it can
With understanding, in practical applications, the present invention can decrease or increase linear measure longimetry group according to the ship school form of tubes actually measured
Part 1 and angle measure component 2.Such as when measuring the handsome pipe of ship of only one straight tube, it is only necessary to one group of length measurement assembly 1 and angle
Measurement assembly 2 can surveying vessel school length of tube and angular rotation of flange needed if ship school pipe is made of 3 straight sections and 2 bent angles
Three groups of length measurement assemblies 1 and angle measure component 2 combine, you can measurement obtain long, bent angle between the point of ship school pipe, corner and
Angular rotation of flange data.
The operation principle of the present invention is that：
First, linear measure longimetry component 1 is elongated to and manages wherein one section of identical length with ship school, pass through linear measure longimetry component
1 scale mark reads the length data that ship school manages wherein one section, when needing to measure the bent angle between the ship school pipe of different segmentations
When, by rotating another linear measure longimetry component 1, so that linear measure longimetry component 1 is managed close to another section of ship school, at this point, reading two groups long
The data of the bent angle Measuring plate between measurement assembly 1 are spent, the bent angle data between two sections of ship school pipes are obtained, simultaneously as ship school
The head end of pipe difference segmentation is connected with flange, at this point, measuring ship school pipe difference by outer corner measurement disk is segmented junction
Flange, to obtain the relative rotation angle of two sections of ship school pipes；
With reference to figure 5~6, in length (L1, L2, L3, L4, L5), bent angle (A1, A2, A3, A4) and the corner for measuring ship school pipe
After (B1, B2, B3, B4, B5) data, above-mentioned data can be calculated by checking module, whether real ship accounting ship school pipe may be used
It bends, solves the problems, such as that ship school pipe measures, calculates and check, improve ship school pipe producing efficiency.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
