A kind of bulge measuring instrument
Technical field
The utility model relates to a kind of bulge measuring instrument, particularly relates to a kind of bulge measuring instrument with digitizing displacement transducer, is applicable to build the technical field detected.
Background technology
A lot of buildings can to the flatness on its surface and smoothness requirements higher, on the steel lining of nuclear power station inside, such as do not allow the phenomenon occurring bulge.Therefore, nuclear power station needs measurement and the process of regularly its steel lining being carried out to bulge.
As shown in Figure 1, which show a kind of bulge measuring instrument of the prior art, comprise support 1, column 2 and handle 6, support 1 is fixed on column 2.Support 1 is also provided with multiple dial gauge 15 with sounding rod 4, and its principle of work is that the small of the sounding rod caused by measured size moves linearly past gear drive amplification, becomes the rotation of pointer on index dial, thus reads the size of measured size.During use, the column 2 of this bulge measuring instrument is placed perpendicular to surface to be measured.If there is bulge on surface to be measured, then can there is different displacements in the sounding rod 4 of the dial gauge 15 of corresponding position, measured the true altitude of bulge by the reading difference of each dial gauge.During reading, need artificial naked eyes reading.After a position measurement, manually measuring instrument is moved forward the distance of regulation, and then artificial reading.Finally, the bulge distributed data in surface to be measured is drawn according to measurement result repeatedly.
Above-mentioned bulge measuring instrument of the prior art needs manually mobile and artificial naked eyes reading, and troublesome poeration, degree of accuracy are not high.When reality uses, can because human error causes the position of bulge and highly distributes not conforming to the actual conditions.Therefore, the bulge measuring instrument that a kind of degree of accuracy is high, easy to operate is badly in need of in prior art.
Utility model content
The utility model relates to a kind of bulge measuring instrument, comprise support, column and handle, support is fixed on column, bulge measuring instrument also comprises guide rail and hub, column can along slide, support is provided with multiple digitizing displacement transducer, and digitizing displacement transducer is connected by connecting line with hub.
Preferably, hub has display screen.
Preferably, digitizing displacement transducer can be capacitor grid transducer.The quantity of digitizing displacement transducer is 8, and hub is eight road hubs.
Preferably, electric supply installation or USB interface is also provided with in hub.
Preferably, guide rail can also be provided with drive motor or be provided with scale.
According to bulge measuring instrument of the present utility model, owing to being provided with guide rail, digitizing displacement transducer and hub etc., therefore it is easy and simple to handle, accuracy is high.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, hereinafter will be described in detail to embodiment of the present utility model by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
As shown in Figures 2 and 3, which show the schematic diagram according to bulge measuring instrument of the present utility model, comprise support 1, column 2, guide rail 3, handle 6 and hub 7.Support 1 is fixed on column 2, and column 2 can slide along guide rail 3.Support 1 is also provided with multiple digitizing displacement transducer 5, such as, can be capacitor grid transducer, and it digitally can read the displacement of sounding rod 4.Digitizing displacement transducer 5 is connected (only illustrating in figure that a connecting line is to show explanation) by connecting line 8 with hub 7.Hub 7 is for storing the measurement data of each digitizing displacement transducer 5.Preferably, hub 7 can also have display screen 9, for showing the measurement data of each digitizing displacement transducer 5 in real time.During measurement, also can hub 7 be connected on computing machine, by the measurement data of each digitizing displacement transducer 5 of Real time vision.
In order to read the convenience of data, hub 7 can also arrange USB interface, after end to be measured, being connected on computing machine and reading measurement result.The number of digitizing displacement transducer 5 and the way of hub 7 can be arranged according to actual needs, 8 digitizing displacement transducers 5 such as can be set and hub be set to eight road hubs (that is, having 8 interfaces of connecting wires also can store simultaneously and show the measurement result of 8 digitizing displacement transducers 5).Preferably, in hub 7, be also provided with electric supply installation, for powering to it.In some cases, also can be set to directly to connect external power supply and power.
Preferably, drive motor can also be installed on guides 3 automatically to slide for driving arm.Scale can also be set on guides 3 to show the distance of support-moving.
Preferably, can fold according to bulge measuring instrument of the present utility model, the length of guide rail 3 can be 50cm, and the length of support can be 100cm.Time folding, handle 6 is pulled down, by support 1 upper and lower doubling from centre position.As shown in Figure 3, which show the broken line L of support 1.Bulge measuring instrument after folding can be placed in suitcase to be carried with.
During use, be fixed on by guide rail 3 on surface to be measured, support 1 moved to one end of guide rail 3, now digitizing displacement transducer 5 reads an initial reading, then support suspends after the other end moves distance to a declared goal such as 50mm, digitizing displacement transducer 5 reading again.Repeat this process until arrive the other end of guide rail 3, thus obtain the bulge distributed data on surface to be measured according to these readings.In measuring process, reading and the storage of data are completed automatically by hub.
Adopt bulge measuring instrument of the present utility model, owing to being provided with guide rail (more preferably, being also provided with drive motor), digitizing displacement transducer and hub etc., therefore it is easy and simple to handle, accuracy is high.
Although the embodiment disclosed by the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technician in any the utility model art; under the prerequisite not departing from the spirit and scope disclosed by the utility model; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
