Abstract
The utility model discloses a full section rail head profile measuring mechanism which includes two rotating arms. One rotating arm B is in a Y-shaped dual-roller structure, and the other rotating arm A is connected with a panel. An angle sensor is arranged between the rotating arm A and the panel, and an angle sensor is arranged between the rotating arm A and the rotating arm B. Through recording the rolling angle information of the rollers on the end of the Y-shaped rotating arm B along the outline of a steel rail, the profile of the steel rail is obtained. The advantages are that the dual-roller Y-shaped rotating arm is adopted, the lower bottom edge and the rail waist of the rail head can be measured, the steel rail interference is avoided, and the profiles of left and right side faces can be measured by one-off positioning.
Description
Technical field
The utility model relates to a kind of measuring mechanism for the full section profile of railway track and abrasion, particularly a kind of full section rail head appearance measuring mechanism.
Background technology
When measuring rail head of rail profile and abrasion, need to measure the position that might occur wearing away, existing measuring mechanism can't reach this requirement.
The utility model content
Technical problem to be solved in the utility model is the full section rail head appearance measuring mechanism that will provide a kind of measuring accuracy high.
In order to solve above technical matters, the utility model provides a kind of full section rail head appearance measuring mechanism, comprise two pivoted arms, one of them pivoted arm B is two roller structures of bifurcation font, another pivoted arm A is connected with a panel, between pivoted arm A and panel, between pivoted arm A and pivoted arm B, angular transducer is arranged all, record the roller of bifurcation font pivoted arm B end along the angle information that rail profile rolls, obtain the profile of rail.
Described bifurcation font pivoted arm B end symmetrical is arranged roller.Pivoted arm B right side roller be used for to be measured rail left side profile, and pivoted arm B left side roller is used for measuring rail right side profile.
Tested rail is placed in the below of the utility model measuring mechanism, and as the located lateral benchmark, rail surface is vertical positioning datum to positioning datum with the medial surface of rail.
The utility model has the advantages that: adopt the bifurcation font pivoted arm of two rollers, can measure bottom and the web of the rail of rail head, avoid the interference with rail, one-time positioning can be measured the profile of left and right sides.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The number in the figure explanation
1-pivoted arm A; 2-pivoted arm B;
3-panel; 4-vertical positioning datum;
5-located lateral benchmark; 6-rail.
Embodiment
See also shown in accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of full section rail head appearance measuring mechanism, comprise two pivoted arms, one of them pivoted arm B2 is two roller structures of bifurcation font, another pivoted arm A1 is connected with a panel 3, between pivoted arm A1 and panel 3, between pivoted arm A1 and pivoted arm B2, angular transducer is arranged all, record the roller of bifurcation font pivoted arm B2 end along the angle information that rail 6 profiles roll, obtain the profile of rail 6.
Described bifurcation font pivoted arm B2 end symmetrical is arranged roller.Pivoted arm B2 right side roller is used for measuring rail 6 left side profiles, and on the left of pivoted arm B2, roller is used for measuring rail 6 right side profiles.
Tested rail 6 is placed in the below of the utility model measuring mechanism, and as located lateral benchmark 5, rail surface is vertical positioning datum 4 to positioning datum with the medial surface of rail.Between pivoted arm A1 and panel 3, between pivoted arm A1 and pivoted arm B2, angular transducer is arranged, when the roller of pivoted arm B2 end rolls along rail 6 profiles, two angular transducer recording angular information, and calculate thus the profile of rail 6.When measuring rail 6 left side profile, roller begins to roll from left side web of the rail middle part, finishes to the rail 6 rail head center lines side that takes over.Same, when measuring rail 6 right side profile, roller begins to be rolled into the end of taking back of rail 6 rail head center lines from right side web of the rail middle part.The profile of rail head top duplicate measurements is used for splicing rail 6 left and right sides appearance profiles.
