Abstract
The utility model discloses a kind of device of mid point positioning control portable pendulum tester sliding length.Comprise mid point anchor point, fascia panel, fork, yaw.Mid point anchor point is gauge point, and fascia panel is the circular arc concave plane plate structure of steel material, and fork is the straight-bar of steel material, and yaw is the box-shaped structure of rectangle, and there is friction rubber sheet lower end.The leg-of-mutton centerline that mid point anchor point is formed for fork and the line of yaw and the 126mm sliding length on sheet rubber and test road surface, this center line is reflected to sliding length test road surface being and needing to check, and just represents that sliding length has been checked when namely fork overlaps with the mid point anchor point of perpendicular line both sides.After have employed the device of mid point anchor point, only need to check corresponding with mid point anchor point for fork accurately sliding length, achieve the rapidity and accuracy of checking sliding length.The utility model is more easily observed, easy and simple to handle, accuracy is high.
Description
Technical field
The utility model relates to a kind of device of mid point positioning control portable pendulum tester sliding length, is applied to the surveying instrument of the friction factor on road surface.
Background technology
According to China's associated specifications requirement, the friction factor index friction factor on road surface represents.At present, the sensing equipment of frequent employing is portable pendulum tester, the operating process that existing instrument is checked at the sliding length carrying out 126mm is too complicated, comprise the process utilizing cushion block to the adjustment of height of instrument and the leveling repeatedly to air level, larger difficulty is caused to checking sliding length accurately in capital, finally cause the waste of surface friction coefficient Measuring Time, measurement target fast and accurately can not be reached.
Summary of the invention
For the defect existed in above-mentioned prior art and deficiency, the purpose of this utility model is, provides a kind of device of mid point positioning control portable pendulum tester sliding length.Mid point anchor point is gauge point, and fascia panel is the circular arc planar panel structure of steel material, and fork is the straight-bar of steel material, and yaw is the box-shaped structure of rectangle, and there is friction rubber sheet lower end.The leg-of-mutton centerline that mid point anchor point is formed for fork and the line of yaw and the 126mm sliding length on sheet rubber and test road surface, this center line is reflected to sliding length test road surface being and needing to check, and just represents that sliding length has been checked when namely fork overlaps with the mid point anchor point of perpendicular line both sides.After have employed the device of mid point anchor point, only need to check corresponding with mid point anchor point for fork accurately sliding length, achieve the rapidity and accuracy of checking sliding length.The utility model is more easily observed, easy and simple to handle, accuracy is high.
In order to reach above object, the utility model adopts following technical solution:
A device for mid point positioning control portable pendulum tester sliding length, comprises mid point anchor point (1), fascia panel (2), fork (3), yaw (4).
Described mid point anchor point (1) is gauge point, left and right relative to perpendicular line each one;
The circular arc planar panel structure that described fascia panel (2) is steel material;
The straight-bar that described fork (3) is steel material;
The box-shaped structure that described yaw (4) is rectangle, there is friction rubber sheet lower end.
Principle of work:
The utility model utilizes two mid point anchor point gauge points left and right relative to perpendicular line on fascia panel, the leg-of-mutton centerline that mid point anchor point is formed for fork and the line of yaw and the 126mm sliding length on sheet rubber and test road surface, this center line is reflected to sliding length test road surface being and needing to check, and just represents that sliding length has been checked when namely fork overlaps with the mid point anchor point of perpendicular line both sides.
Compared with prior art, the utility model has the advantages that:
After have employed the device of mid point anchor point, only need to check corresponding with mid point anchor point for fork accurately sliding length, achieve the rapidity and accuracy of checking sliding length.The utility model is more easily observed, easy and simple to handle, accuracy is high.
