Description
Technical field
The utility model is related to deflection measuring apparatus, more particularly, to a kind of target center special measuring tool.
Background technology
For a long time, one of most important component in shipbuilding center shafting is Ship Power Equipment, thus people couple
It also pay with very big concern.In 10,000 tons ship, for long axis system or short axle system, the peace of single shafting or twin shafting
Dress, the shafting bracing wire positioning process that we use at present is substantially similar, but utilization of the user on survey tool
Final result can be caused measured deviation and so that measurement result and theoretical values deviation too greatly so as to influence the safety of ship
Performance and used life.
When in super-long object bracing wire pair, such as long axis system (＞ 15m), light target center and wire relative position are being determined
When generally use clamp go to measure, during caliper measurements, steel wire is easily swung and manual operation error is big, it is impossible to intuitively show number
Value.Since the dead weight of steel wire can generate amount of deflection, the degree of disturbing at steel wire any point can be calculated by formula, then calculate 4 surveys
The difference for measuring point (up and down) proofreads degree of the disturbing deviation of practical steel wire.The worker that rich experiences are also required for during measurement is grasped
Make.

Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is equipped with sleeve 5 and positioning disk 1, sleeve 5 with positioning disk 1 is concentric sets
Meter, and sleeve 5 is fixedly connected with positioning disk 1；Positioning disk 1 is equipped with the wire casing 2 from the center of circle to edge, and 2 width of wire casing is 1mm；Line
Scale 3 is equipped at slot 2, scale 3 is set from circle centre position along 2 length direction of wire casing；2 top of wire casing is equipped with level meter 4, level meter 4
Perpendicular to 2 length direction of wire casing.
During carrying out in shafting bracing wire school, target center special measuring tool needs are matched with light target seat, target center special measuring tool
5 outer diameter of sleeve and light target seat endoporus are concentric, and it is 0.02mmm to install fit clearance.To coordinate different size of light target seat, this reality
With 1 a diameter of 15-100mm of novel positioning disk, target center special measuring tool height is 30-100mm.
Application method of this target center special measuring tool during carrying out in Shafting Alignment of Vessels be：
1. determining two datum marks, straight line determined by two datum marks is theoretical centerline.
2. wire pulling rack is installed in fixed position, and draws the steel wire of one a diameter of 0.5~1.0, steel is adjusted according to initial and end datum mark
Silk position, makes steel wire pass through fore-aft datum marks, at this moment steel wire just represents shafting theoretical centerline；If it and is equipped between guy wire support
Dry light target seat, light target seat are matched with target center special measuring tool.
3. when doing horizontal measurement, since the dead weight of steel wire can generate amount of deflection, tested point amount of deflection is calculated by formula；Adjustment
The position of target center special measuring tool at tested point makes 2 length direction of wire casing perpendicular to horizontal line, while steel wire passes through positioning disk 1
Wire casing 2, but steel wire is not contacted with wire casing 2 during measurement；Preferably, the surface roughness of sleeve outer surface is 1.6 μm.
4. adjusting light target seat height degree, 3 corresponding numerical value of scale at steel wire is made to be equal to the amount of deflection calculated；Positioning disk 1 at this time
The center of circle be located on theoretical centerline.
Target center special measuring tool positioning disk 1 can be optimized for it is interior hollow, disk body of the positioning disk 1 far from 5 side of sleeve be band scale
Organic glass, organic glass be equipped with fluorescent film.And disk body of the positioning disk 1 far from 5 side of sleeve is equipped with cross scale
Line, the center of the cross graduation mark are located at the center of circle of positioning disk 1, and a wherein line and the wire casing 2 of the cross graduation mark hang down
Directly.
When being reviewed, micro- collimating telescope, micro- collimating telescope cross are equipped between guy wire support and light target seat
Graduation mark center is located on theoretical centerline；The positioning disk 1 of height has been adjusted by the observation of micro- collimating telescope, has worked as positioning
When 1 cross graduation mark of disk is overlapped with micro- collimating telescope cross graduation mark, it was demonstrated that the point is located on theoretical centerline.
In order to make more to be accurately positioned 1 circle centre position of disk in school equipped with threading hole, threading hole is connected with wire casing 2.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies or the equivalent variations made according to the utility model patent protection domain and modification,
It all should still belong to the scope that the utility model claims book is covered.
