Description
Technical field
Rope sensor truing tool is the utility model is related to, belongs to gathering pipe fields of measurement.
Background technology
Be covered with pipeline in ship everywhere, the designs of these pipe fittings, make and in board install after a system such as inspection
The operation of row is referred to as " pipe laying ".Usual ship is sectional construction, is just needed in segment folding time-division intersegmental pipeline
Gathering pipe can not produce miscellaneous gathering pipe to connect by pipeline designs drawing, and the making of gathering pipe is generally adopted
Take type method and site welding connection.Both approaches have the following disadvantages：(1) precision is not high, can there is 5% defective work
(2) activity duration is grown, and in transport operation, contingency is multiple, and potential safety hazard (3) be present needs the backmans such as flange and angle bar
Have, cause the operations such as welding in waste of material (4) ship, cutting disaster hidden-trouble (5) needs to be present and be skilled in technique, be veteran special
Industry skilled worker could be completed in pipeline makes the most it is difficult to " ensureing the good precision of finished product ".But use both above side
Often the gathering pipe flange bolt hole malposition produced often still occurs using both above method in method, causes
Situation about can not install.
Patent zl201110323558.x provides a kind of spherical coordinate measuring machine for gathering pipe measurement, and the device can
With the quickly accurately locus of two flanges to be closed up of measurement, and be processed into gathering pipe and make drawing, in shipbuilding industry
Large-scale application is obtained.The linear measure longimetry device of the gathering pipe measuring machine is a rope sensor, rope sensor
Measuring principle is that the encoder one inside drawstring drives changes, and passes through the cooperation of internal circuit and supporting machinery structure, coding
Certain rule can be showed between the signal intensity of device and the length change of drawstring, in use, by certain circuit and
Algorithm, read out the signal intensity of encoder, you can to calculate pulling rope length change.But in rope sensor manufacturing process
In can have certain error, usually 0.5 ‰, i.e., per error of meter 0.5mm, when measure length it is bigger when, this error
It can linearly rise, the corresponding relation of encoder code value and pulling rope length is changed, be calculated by original corresponding relation
Pulling rope length and reality pulling rope length between larger error be present, finally influence measurement result, cause measurement accuracy to be deteriorated,
On the other hand, easily cause drawstring during measurement process medium pulling rope is put back in continuous pull-out to reverse, drawstring, which reverses, also can
The precision of pulling rope length is impacted, finally influences measurement accuracy.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, the utility model provides a kind of drawstring sensing
Device truing tool, the instrument small volume is in light weight, can correct data at any time, can be used as and close up the daily essence of cell measurement apparatus
Spend the instrument of amendment.
Technical scheme：To achieve the above object, a kind of rope sensor truing tool of the present utility model, including base and
Bearing bracket stand, the bearing are connected with base by connecting rod, and the base is provided with two through holes be arrangeding in parallel, and respectively first
Through hole and the second through hole, vertical rod are inserted into first through hole, and the second through hole is provided with the crossed beam trunking parallel with the second through-bore axis, institute
State bearing bracket stand and include great circle loop-drive, parallel boss is extended with the indentation, there of great circle loop-drive, axle is installed on boss, in axle
On bearing is installed, great circle loop-drive is stuck in vertical rod.
Preferably, the bottom surface of the base is plane, the plane is vertical with the axis of first through hole.
Preferably, the bearing be arranged in parallel with crossed beam trunking.
In the utility model, above-mentioned base is stainless steel, and the second through hole is arranged at bottom, and there are crossed beam trunking, top in side
There is the first circular hole, vertical rod is a stainless steel round bar, and one end is arranged in the circular hole of base, other end installation bearing bracket stand, bearing bracket stand
For stainless steel, there is square groove one end, and the other end has a circular hole, and the other end of vertical rod is mounted in the circular hole, and bearing is mounted in side
In shape groove, axle fills within the bearing, and on bearing bracket stand.Above-mentioned base end face is flat, and being one has high light cleanliness
With the plane of position degree requirement, the circular hole in the plane and base is vertical.The position of bearing bracket stand is adjusted after after bearing bracket stand installation,
Make bearing parallel with the crossed beam trunking of base, the two line is parallel with vertical rod.Regulation after measurement base bottom portion of groove plane with
The distance of bearing centre, this distance are accurately measured using conventional slide measure, and by this size marking to base, remember this size
For L.During amendment, base is close on the rope stretching head plane of spherical coordinates measuring machine, drawstring is pulled out, line is crossed through base
Groove, and hook is hung on bearing, the code value M of now encoder is read by PDA, is now above-mentioned length corresponding to code value M
L is spent, and is accurate corresponding, code value M and length L are input in PDA, PDA Survey Softwares can correct coding automatically
The corresponding relation of device code value and pulling rope length, eliminate error.
Beneficial effect：The utility model uses simple structure, can fast, accurately correct pulling rope length and encoder
The corresponding relation of code value, measurement of length error is eliminated, keep measuring machine measurement accuracy, and as daily adjustment in accuracy hand
Section, measuring machine measurement accuracy can be made to be constantly in stable state.
