Description
Technical field
The utility model relates to a kind of distance measuring equipment, is specifically related to a kind of wheeled electro-optical distance instrument.
Background technology
In the prior art, the instrument that people's measuring distance is adopted is mainly traditional boxlike tape, and is particularly all the more so for various in-site measurements, and for example the scene of a traffic accident is measured.In use there are the following problems for the boxlike tape: one, limited length, and when on-the-spot scope was big, use can be restricted; When two, the scene needed to measure curve, it used very inconvenience; Must could be implemented to measure by two people's cooperations when three, operating, speed be slow, and efficient is low; Four, when night or insufficient light, must be aided with light and just can see measurement data clearly.Five, material is subject to factor affecting such as environment temperature, humidity, and measuring error is bigger.
The utility model content
The purpose of this utility model provides a kind of wheeled electro-optical distance instrument, and it utilizes photosignal to carry out range observation, and shows measurement result by count table.
For realizing this purpose, the utility model provides a kind of wheeled electro-optical distance instrument, it comprises housing, intermediate shaft, road wheel, handle, photometry sheet, optoelectronic switch, count table, the housing two ends are provided with axis hole, intermediate shaft is hubbed in this axis hole, road wheel and photometry sheet are fixedly installed on the intermediate shaft, and optoelectronic switch comprises power valve. the corresponding respectively both sides that are arranged in the photometry sheet of receiving tube and amplifier, power valve and receiving tube.With power valve and corresponding radial position place of receiving tube, evenly be provided with elongated slot on the photometry sheet in the annular array mode.
During the utility model work, road wheel is rolled along the measuring position, the photometry sheet rotates thereupon, and optoelectronic switch is an electric signal with the displacement conversion of photometry sheet, and shows measurement data by count table.It has following advantage: one, adopt the ranging technology of photoelectricity combination, and be not subjected to the influence of environment temperature, humidity substantially, measurement data is accurate; Two, count table shows, one way continuous coverage distance can be counted after distance reaches maximum range again, and it is unrestricted to measure length; Three, road wheel can roll actuating along any track, can be convenient for measuring length of curve; Four, volume is little, in light weight, only needs one man operation, the efficiency of measurement height.

Embodiment
See Fig. 1 to Fig. 4, wheeled electro-optical distance instrument described in the utility model comprises housing 2, intermediate shaft 10, road wheel 1, handle 5, photometry sheet 11, optoelectronic switch, count table 6, housing 2 two ends are provided with axis hole, intermediate shaft 10 is hubbed in this axis hole, road wheel 1 and photometry sheet 11 are fixedly installed on the intermediate shaft 10, optoelectronic switch is made up of power valve 8, receiving tube 9 and an amplifier, the corresponding respectively both sides that are arranged in photometry sheet 11 of power valve 8 and receiving tube 9, and handle 5 is fixedly connected with housing 2.During use, hold handle 5, promote road wheel 1 and roll along the measuring position, then intermediate shaft 10 rotates with photometry sheet 11 thereupon.Simultaneously, optoelectronic switch is an electric signal with the displacement conversion of photometry sheet 11, and shows measurement data by count table.Wherein, photometry sheet 11 is the plates of a circle, evenly is provided with a circle elongated slot with power valve 8 and receiving tube 9 corresponding radially disposal in the annular array mode on it.During work, power valve 8 sends light signal to receiving tube 9 positions because the corresponding respectively both sides that are arranged in photometry sheet 11 of power valve 8 and receiving tube 9, when the position of elongated slot 12 and power valve 8 and receiving tube 9 not to timing, photometry sheet 11 stops that with light signal receiving tube 9 can not receive light signal.Promote this stadimeter, photometry sheet 11 will rotate an angle, when the position of elongated slot 12 and power valve 8 and receiving tube 9 to timing, light signal will be by elongated slot 12, be received 9 receptions of pipe, receiving tube 9 is converted to electric signal with this light signal, and amplifies by amplifier, send into rolling counters forward then once, certain distance has been moved in expression.Also available circular hole of elongated slot 12 on this photometry sheet 11 or other forms of groove structure replace, and action principle is the same.
Installation for ease of power valve 8 and receiving tube 9, the utility model in the specific implementation, can in housing 2, establish a support 7, in the middle of the support 7 is a recess, its two ends are corresponding formation upper convex portion respectively, this two ends upper convex portion is arranged with respect to photometry sheet 11 both sides respectively, power valve and receiving tube are separately positioned on its two ends upper convex portion.
In the utility model, the quantity of road wheel 1 can be one, two, three or the fourth class, all can realize its purpose by a definite form.For example, as a kind of better embodiment of the present utility model, be provided with two road wheels 1, it is separately positioned on the two ends of intermediate shaft 10.
In a kind of embodiment of the present utility model, also be provided with a location mark 4, it is hubbed at intermediate shaft 10 1 ends, and is free hang all the time, and its lower end is a tip.So, during work, be convenient to observe the starting point and the terminating point of measurement, can effectively improve the accuracy of measurement result.The location mark also can be processed as the right angle form, and promptly its lower end is bent into the right angle state laterally, with starting point and the terminating point of handled easily person from the measurement of top Direct observation.Work during for ease of night or insufficient light, this mark surface, location can apply luminescent material, also can stick the pad pasting that luminescent material is made.
For adapt to different operating person and working condition requirement, handle 3 wherein can be a kind of scalable pull bar form.
Count table generally is provided with reset switch, can at any time the count table video data be re-set as zero, is convenient to begin at any time measure or counting.When the utility model is specifically implemented, the reset switch 5 of count table is arranged on the top of handle 3, makes faster and more convenient operation.Count table can adopt LED or LCD count table.Like this, even when night or insufficient light, work, do not influence survey measurements yet.
