Abstract
The utility model discloses a kind of Bending Deformation detection devices of rigid objects, belong to heat supply process field, including absolute value encoder, rolling bearing, measurement wheel and from coil spring, absolute value encoder is sequentially connected rolling bearing, measurement wheel and from coil spring, the shaft of absolute value encoder and the shaft of pulley and the shaft from coil spring are coaxial linkages, and wirerope moves on measurement wheel and wirerope by tightening always from coil spring.Wirerope is converted into the measurement of rotation amount by the straight-line displacement of wirerope by tightening always from coil spring in the utility model.For wirerope tightly around on multi-turn measurement wheel, every circle stroke is identical, therefore is linear measurement in entire measurement range.
Description
Technical field
The utility model relates to heat supply process field, in particular to the Bending Deformation detection device of a kind of rigid objects.
Background technique
In heating field, since the length of pipeline is always limited, pipeline and pipeline always have the place of interface, due to
Expanding with heat and contract with cold leads to pipeline extension, and general way is to add a compensator in interface, has many compensators to draw using rigidity
Bar come prevent from stretching it is excessive cause compensator to damage, the Bending Deformation of pull rod is an emphasis check object of heat supply company.
It is currently that server is sent to using camera shooting video, voice recognition Bending Deformation is checked by related personnel
Degree.But since interface position is generally all very remote, without external power supply, using battery powered words, due to imaging greatest service
Consumption is very big, needs frequently artificial charging, very cumbersome.
Utility model content
The purpose of this utility model is to provide a kind of Bending Deformation detection devices of rigid objects, with the automatic of low-power consumption
Detect Bending Deformation degree.
In order to achieve the above object, the utility model uses a kind of Bending Deformation detection device of rigid objects, including absolute
Value encoder, rolling bearing, measurement takes turns and from coil spring, absolute value encoder is sequentially connected rolling bearing, measurement wheel and rolls up certainly
Spring, the shaft of absolute value encoder and the shaft of pulley and the shaft from coil spring are coaxial linkages, and wirerope is taken turns in measurement
Upper movement and wirerope by tightening always from coil spring.
It further, further include NB-IOT module and server, the absolute value encoder passes through NB-IOT module kimonos
Business device connection.
Further, the inner ring of rolling bearing is fixed on the axis of measurement wheel, and the inner ring of absolute value encoder is fixed on survey
On the axis for measuring wheel, from the axis that the center of coil spring is fixed on measurement wheel.
Compared with prior art, there are following technical effects for the utility model: wirerope is by volume bullet certainly in the utility model
Spring is tightened always, and the measurement of rotation amount is converted by the straight-line displacement of wirerope.Wirerope is taken turns tightly around in multi-turn measurement, every circle
Stroke is identical, therefore is linear measurement in entire measurement range.Wirerope measurement wheel, wind spring wheel coaxially join with sensor
Dynamic, connection error minimizes.
Detailed description of the invention
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail:
Fig. 1 is a kind of structural schematic diagram of the Bending Deformation detection device of rigid objects；
Fig. 2 is Bending Deformation detection schematic diagram.
Specific embodiment
In order to further explain the feature of the utility model, please refer to detailed description below in connection with the utility model with
Attached drawing.Institute's attached drawing is only for reference and purposes of discussion, is not used to limit the protection scope of the utility model.
As shown in Figure 1, present embodiment discloses a kind of Bending Deformation detection device of rigid objects, including absolute encoder
Device 1, rolling bearing 2, measurement takes turns 3 and from coil spring 4, absolute value encoder 1 is sequentially connected rolling bearing 2, measurement wheel 3 and rolls up certainly
Spring 4, the shaft of absolute value encoder 1 and the shaft of pulley and shaft from coil spring 4 are coaxial linkages, and wirerope is measuring
It is moved on wheel 3 and wirerope by tightening always from coil spring 4.Wherein, current displacement is read in absolute value encoder 1.Measurement wheel
3 for seizing wire on measurement wheel 3 for moving, and wirerope by tightening always from coil spring 4, from coil spring 4 for tightening steel
Cord.Wherein, the axis of measurement wheel 3 is longer, and the inner ring of rolling bearing 2 is fixed on the axis of measurement wheel 3, absolute value encoder 1
Inner ring is fixed on the axis of measurement wheel 3, from the axis that the center of coil spring 4 is fixed on measurement wheel 3.
Its testing principle are as follows: wirerope is converted into rotation amount by tightening always from coil spring 4, by the straight-line displacement of wirerope
Measurement.For wirerope tightly around on multi-turn measurement wheel 3, every circle stroke is identical, therefore is linear survey in entire measurement range
Amount.Meanwhile wirerope measurement wheel 3, wind spring wheel and sensor coaxial linkage, connection error minimize.
As shown in Fig. 2, the shift value measured is a before deformation occurs, it is b that shift value is measured when deformation occurs,
Then the difference h of a and b is exactly the changing value being displaced, and the Bending Deformation degree of rigid objects can be assessed by h.
It further, further include NB-IOT module and server, the absolute value encoder passes through NB-IOT module kimonos
Business device connection.Server is sent by NB-IOT module by h value using matched communication module, server can be according to h value
The case where provide warning information automatically and send relevant person in charge in a manner of short message etc., to be handled in time, avoid situation
A more step deteriorates.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
