Abstract
Strain measurement quantity sensor, it has a response body, has through hole in the middle part of response body, the inwall of through hole is pasted with foil gauge, foil gauge connects with cable, and the position between response body both ends and through hole has one section of transitional zone respectively, the thickness of transitional zone and the smooth contraction of width.Due to the existence of transitional zone on response body, when bearing beam is installed the variable survey sensor that the utility model provides, under the situation of the installed surface injustice of bearing beam, by the elastic deformation of transitional zone, make response body and the comparatively ideal docile of bearing beam, and then realize in use measuring more accurately.The utility model is rational in infrastructure, use is reliable, and it can adapt to install on the poor strain beam of flatness, and has good measuring accuracy.
Description
Technical field
The utility model relates to dependent variable measurement mechanism, specifically a kind of strain measurement quantity sensor.
Background technology
For the dependent variable when bearing beam measured on some equipment moves at work, usually strain measurement quantity sensor is installed on strain beam.Such as, for walking-beam pumping unit, be the dependent variable of its walking beam in surveying work, the means adopted at present are on walking beam, install strain measurement quantity sensor.The basic structure of existing a kind of strain measurement quantity sensor is have through hole in the middle part of a response body, and the inwall of through hole is pasted with foil gauge, and foil gauge connects with cable.The shortcoming that existing this strain measurement quantity sensor in use exists is: when 1, response body is installed on the poor bearing beam of surface planarity, be difficult to be affixed more closely with bearing beam, and then affect measuring accuracy; 2, on bearing beam, inconvenience is installed.
Utility model content
The purpose of this utility model is to provide a kind of strain measurement quantity sensor, this variable survey sensor good measuring accuracy, easy for installation.
For achieving the above object, the utility model adopts following scheme: strain measurement quantity sensor, it has a response body, through hole is had in the middle part of response body, the inwall of through hole is pasted with foil gauge, foil gauge connects with the cable that response body is connected with, and the position between response body both ends and through hole has one section of transitional zone respectively, the thickness of transitional zone and the smooth contraction of width.
From such scheme, due to the existence of transitional zone on response body, when bearing beam is installed the variable survey sensor that the utility model provides, under the situation of the installed surface injustice of bearing beam, by the elastic deformation of transitional zone, make response body and the comparatively ideal laminating of bearing beam, and then realize in use measuring more accurately.
The utility model is rational in infrastructure, use is reliable, and it can adapt to install on the poor strain beam of flatness, and has good measuring accuracy.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model one embodiment;
The vertical view of Fig. 2 Fig. 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2
The strain measurement quantity sensor that the utility model provides, it has a response body 1, has through hole 1b in the middle part of response body 1, and the inwall of through hole 1b is pasted with foil gauge, and foil gauge connects with the cable 2 that response body 1 is connected with.Position between response body 1 both ends and through hole has one section of transitional zone 1a respectively, the thickness of transitional zone 1a and the smooth contraction of width.The attaching of above-described foil gauge and the mode connected with cable 2 thereof are prior art, therefore, do not illustrate foil gauge and the connection with cable thereof in the accompanying drawings.In addition, transitional zone 1a is the face of cylinder in the both sides of Width, thickness direction.
In the present embodiment, the lower surface of response body 1 is connected with a base plate 3, base plate 3 is in tortuous roundabout paliform.Should be connected with strain beam by base plate in use by variable survey sensor, can be arranged on strain beam.By punching on base plate 3, being connected with strain beam by base plate with web member, or to be welded with strain beam by base plate, realization should the installation of variable survey sensor.When the flatness of the installed surface of bearing beam is not good, by the elastic deformation of base plate 3, make itself and the comparatively ideal laminating of bearing beam, and then guarantee measuring accuracy.
Claims (3)
1. strain measurement quantity sensor, it has a response body, through hole is had in the middle part of response body, the inwall of through hole is pasted with foil gauge, foil gauge connects with the cable that response body is connected with, it is characterized in that: the position between response body both ends and through hole has one section of transitional zone respectively, the thickness of transitional zone and the smooth contraction of width.
