Abstract

The utility model discloses a quick calibration type road surface frictionmeter, which includes a base, a guide rail type stand column, a lifting mechanism provided with a height fixing knob and a height adjusting knob, a dial provided with a cantilever and swinging value scale marks, a pendulum shaft, a pendulum rod rotating around the pendulum shaft, a pointer rotating around the pendulum shaft and pointing the swinging value scale marks, and a pendulum head, wherein an electronic level meter is mounted on the base. The quick calibration type road surface frictionmeter can further quickly enhance the metering accuracy of the road surface friction coefficient.

Description

Fast Calibration type surface friction coefficient analyzer

Technical field

The utility model belongs to the improvement of pendulum friction coefficient determinator structure, particularly Fast Calibration type surface friction coefficient analyzer.

Background technology

Development along with the communications and transportation cause, highway, the anti-skidding problem on the road surface such as urban road and airfield runway has caused the generally attention of relevant department, existing pendulum friction coefficient determinator (abbreviation portable pendulum tester) is used to measure various highway pavements, airfield runway, the friction factor of marking paint etc., even according to the relevant coefficients of friction of its mensuration to determine the synthesizing formula of tire, but, adopt existing portable pendulum tester to use its pedestal that has of traditional level meter leveling with spirit bubble, its sliding length of rubber gasket that causes smooth bottom to have can not be accurate, in time adjust to the right place, need repeatedly to check, attempt, finally cause the surface friction coefficient (pendulum value) measured accurate not.

The utility model content

The purpose of this utility model is to provide a kind of Fast Calibration type surface friction coefficient analyzer, can further improve fast the degree of accuracy of the surface friction coefficient of measuring.

The purpose of this utility model is achieved in that a kind of Fast Calibration type surface friction coefficient analyzer, comprises base, guide tracked column, is accompanied with height fixed knob and the elevating mechanism of height adjustment knob, the scale with cantilever and pendulum value scale mark, balance staff, the fork that rotates around balance staff, rotates and pointer and the yaw of indication pendulum value scale mark around balance staff; Be fixedly mounted with the guide tracked column of erectting at base, at guide tracked column cylinder the elevating mechanism that its body of rod length direction slides up and down is installed, the height fixed knob is fastened on elevating mechanism on the guide tracked column in the turn mode, height adjustment knob makes elevating mechanism slide up and down along its body of rod length direction in the turn mode, fixed scale is being set and balance staff is being installed at elevating mechanism, drawing at scale has pendulum value scale mark, the butt of balance staff and fork, the butt of pointer connects, the top of fork is being fixedly mounted with yaw, tail end at yaw is installed with balance bob, movable lifting handle and fixed set screw are being set at the yaw back side, limited smooth of scope of activities is being set in the yaw bottom surface; In the yaw bottom surface groove is being set, be fixedly mounted with rubber sheet gasket smooth bottom surface, synchronously smooth of drive of lifting handle by manual control enters or breaks away from groove, the body of rod is being fixedly mounted with snap ring at the middle part of fork, the release-push of the snap ring release that it can be blocked automatically is installed at the cantilever tail end, on the cylinder above guide tracked column is positioned at balance staff the angle fixed knob is installed also, the angle fixed knob can make in the mode of self turn the interfix locking and the angle between fork, pointer and the surface level is fixed of fork, pointer and balance staff; On guide tracked column top portable handle is being set; Base has the leveling bolt that supports its pedestal and its pedestal can be adjusted to level; At base electrolevel is installed.

Core technology of the present utility model is characterized as it and has electrolevel, and is self-evident, and its levelness reading is more accurate, eliminated at least the accurate not measuring result error that causes of the levelness of judging because of people's naked eyes.Prove by experiment, the utility model can further improve the degree of accuracy of surface friction coefficient really fast, reduces the labour intensity that on-the-spot surface friction coefficient is measured personnel.
