Contact, and can be along track travel；Mobile unit includes two grooves that Open Side Down and the guide wheel in groove, two grooves
It is connected by connecting bracket, track is embedded into groove, and at least one sensor is equipped in every groove, and sensor passes through guide wheel
With rail contact；Sensor detects track vertical height delta data；Track vertical height delta data is transferred to acquisition host,
It acquires host and describes deflection of bridge span change curve according to the data, obtain deflection of bridge span index value.
The sensor is inclination sensor；Guide wheel is located on the inclino-probe of inclination sensor.
The guide wheel is equipped with two pairs.Two pairs of guide wheel spacing on the inclino-probe are 500mm.
The utility model compared with prior art, has the following advantages that and advantageous effect：The prior art is by fixed
The data that position measures different time carry out comparing calculation, obtain degree of the disturbing changing value of the position bridge.The present apparatus can basis
Field condition arbitrarily obtains the data of different location, then according to the data forming curves of the different location of acquisition；And it does not need
Measuring point is installed to implement on bridge, is contrasted by the data and curves that different time measures, calculates the bridge of same position
The variation for degree of disturbing.The present apparatus can carry out arbitrarily adjusting test position according to field condition, be not required to install on bridge any permanent
Facility reduces artificial and equipment cost.

Specific implementation mode
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
Embodiment
As shown in Figure 1, the utility model detection device includes mobile unit, connecting bracket 2, acquisition host and at least two
Sensor 4.Mobile unit and rail contact, and can be along track travel (hand push is electronic)；Mobile unit includes two openings
Downward groove 1, two grooves 1 are connected by connecting bracket 2, and track is embedded into groove, and at least one is equipped in every groove
A sensor；Referring to Fig. 2, sensor 4 is contacted by guide wheel 5 with track 6, to detect track vertical height delta data；Track
Vertical height delta data is transferred to acquisition host, and acquisition host describes deflection of bridge span change curve according to the data, obtains bridge
Beam deflection index value.
Since the present apparatus can be moved along track, thus the data such as track vertical height variation can be according to field condition
It arbitrarily obtains, then according to the data forming curves of the different location of acquisition, and measuring point implementation need not be installed on bridge, lead to
It crosses the data and curves that different time measures to be contrasted, calculates the variation of same position bridge degree of disturbing.
When carrying out deflection of bridge span detection using the utility model, the present apparatus is placed it is in orbit, using Manual-pushing or
The electric drive present apparatus travels in orbit, by the required distance measured, takes data；It acquires host and is equipped with control display screen 3,
Can display distance and numerical value, control display screen 3 is located in connecting bracket 2.It, can root when being detected to same bridge for second
Corresponding data are acquired according to the detecting distance of first time, or adjust measurement distance as needed.Fig. 3 and Fig. 4 is the detection device
Detection usage state diagram, it can be seen that sensor be contact track installation.Fig. 5 is the tested of the data formation that detection obtains
Degree of the disturbing change curve of survey bridge, can be seen that from the data graphs after detecting for the first time, the variation detected every time
The accumulative changing value of situation and corresponding different distance.
In the present embodiment, track uses rail；Sensor is inclination sensor, is placed in above rail, by cable 7 with
Acquire host connection.Inclination sensor will be detected identification to the vertical height delta data of track, using the survey with guide wheel
Angle probe, two couples of guide wheel spacing about 500mm on inclino-probe are a survey section with the spacing between two pairs of guide wheels.Each survey
Relative level departure δ can be calculate by the following formula to obtain between the upper and lower guide wheel of section.
δ=l × sin θ
In formula：L is forward and backward guide wheel spacing；θ is the angle popped one's head between sensitive axes and trunnion axis.Section n is surveyed relative to starting
The height tolerance amount Δ of pointn, by lighting the δ that follow-on test obtains from startingiIt is accumulative to form, i.e.,：
In formula：δ0The height tolerance amount (mm) of section is surveyed for starting；ΔnHeight tolerance amount for measuring point n relative to starting point
(mm)。
Wherein, each starting point should be arranged at the more stable bridge pier pier top of opposite vertical deformation, be measured due to sensor
It is the relative relief of (500mm distances) between two pairs of guide wheels, so the fixed point of institute's survey bridge must be selected as the base measured
On schedule, generally using bridge pier pier top as fixed point, the absolute elevation of the point is measured with spirit level or miscellaneous equipment, it is tested to extrapolate
Bridge different location actually disturbs angle value.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiment of the utility model is not by above-mentioned
The limitation of embodiment, under other any Spirit Essences and principle without departing from the utility model made by change, modify, replace
In generation, simplifies combination, should be equivalent substitute mode, is included within the scope of protection of the utility model.
