Abstract
The utility model discloses a kind of mounting structure for steel rail smoothness testing agency, it includes crossbeam, is respectively fixedly connected with two support arms in crossbeam both sides, the two support arms difference is outward-dipping so that the detection line of the steel rail smoothness testing agency being fixedly mounted on two support arms is in 120 degree of angles.The mounting structure for steel rail smoothness testing agency provided using the utility model, the detection line of the steel rail smoothness testing agency being fixedly mounted on two support arms can be made to intersect without overlapping on rail surface, not only can effectively solve the signal interference problem caused by overlap, improve certainty of measurement, and can comprehensively gather the contour images of rail, have the advantages that simple structure, certainty of measurement are high, high speed, Dynamic High-accuracy measurement are especially suitable for, with obvious practical value.
Description
Technical field
The utility model is to be related to a kind of mounting structure for steel rail smoothness testing agency, belongs to track
Field.
Background technology
With the development of China's rail transport, railway carries substantial amounts of passenger and freight task.It is long-term in rolling stock
Frequently, in the presence of heavy duty, rail can not only occur permanent deformation, and can sharp wear, wherein sharp radius curve silent partners
Lateral wearing is particularly acute.When abrasion exceedes certain limit, rail head cross-section will lose with wheel tread and match, and will have a strong impact on
High-speed railway driving stationarity, high risks are caused to traffic safety.Therefore, the measurement to rail wear is guarantee railway
The necessary links of safe operation.
However, existing non-contact optical testing agency is mounted on the top surface of each rail, there is sensor signal
Overlap, interfered between the signal for causing reflection passback sensor, so that the profile of rail can not be gathered comprehensively, thus influence
To the accuracy of detection of steel rail smoothness.
Utility model content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to provide and a kind of the profile of rail can be entered
Row is gathered and the accuracy of detection mounting structure for steel rail smoothness testing agency high comprehensively.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of mounting structure for steel rail smoothness testing agency, including crossbeam, be respectively fixedly connected with crossbeam both sides
Two support arms, two support arm difference is outward-dipping so that the steel rail smoothness testing agency being fixedly mounted on two support arms
Detection line is in 120 degree of angles.
A kind of embodiment, the Liang Ge steel rail smoothness testing agency being fixedly mounted on two support arms is symmetricly set in opposite directions
The both sides of rail.
Preferably, the steel rail smoothness testing agency is image acquisition device.
Preferably, described image collector includes laser sensor and image pick-up card.
Preferably, the laser sensor uses linear laser sensor.
Compared to prior art, Advantageous Effects of the present utility model are：
The mounting structure for steel rail smoothness testing agency provided using the utility model, can make to be fixedly mounted on two
The detection line of the steel rail smoothness testing agency on support arm intersects without overlapping on rail surface, not only can effectively solve
Signal interference problem caused by overlap, raising certainty of measurement, and the contour images of rail can be comprehensively gathered, with structure letter
Singly, the advantages of certainty of measurement is high, is especially suitable for high speed, Dynamic High-accuracy measurement, with obvious practical value.
Brief description of the drawings
Fig. 1 is the schematic diagram of the mounting structure for steel rail smoothness testing agency that the utility model is provided.
Label is schematically as follows in figure：1st, crossbeam；2nd, support arm；3rd, steel rail smoothness testing agency；4th, rail.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of mounting structure for steel rail smoothness testing agency that the utility model is provided, including horizontal stroke
Beam 1, two support arms 2 in the both sides of crossbeam 1 are respectively fixedly connected with, two support arm 2 distinguishes outward-dipping so that be fixedly mounted on two
The detection line of the steel rail smoothness testing agency 3 on support arm 2 is in 120 degree of angles.
A kind of embodiment, the Liang Ge steel rail smoothness testing agency 3 being fixedly mounted on two support arms 2 is symmetrical arranged in opposite directions
In the both sides of rail 4, the steel rail smoothness testing agency 3 is image acquisition device, and described image collector includes laser sensing
Device and image pick-up card.The laser sensor typically uses linear laser sensor, is beneficial to its laser signal energy for sending
It is irradiated on the surface of rail 4, and can be reflected back in corresponding linear laser sensor, so as to is conducive to Overall Acquisition rail 4
Contour images.
The mounting structure for steel rail smoothness testing agency that the utility model is provided can be installed on the rail inspection of traveling
Che Shang, can also be applied in special detection means, applied widely.
Finally be necessary it is pointed out here that be：The foregoing is only the utility model preferably specific embodiment, but this
The protection domain of utility model is not limited thereto, and any one skilled in the art discloses in the utility model
In technical scope, the change or replacement that can be readily occurred in should all be covered within protection domain of the present utility model.
