Description
Technical field
The utility model relates to pick-up unit field, especially a kind of high speed swinging friction coefficient proving installation.
Background technology
Along with the development of communications and transportation cause, the anti-skidding problem on the road surfaces such as highways and streets and airfield runway, has caused the generally attention of relevant department.Pendulum friction coefficient determinator (abbreviation portable pendulum tester) is that a kind of for measuring the instrument of the friction factor such as road surface, airfield runway, marking paint, it also can pass through the mensuration to typical surface friction coefficient, as determine various tire formulations according to one of.Portable pendulum tester is kinetic swing impingement instrument, and it is to develop according to " when the elevation loss of pendulum equals to be installed on swing arm end sheet rubber and slips over road surface, overcoming the friction institute works such as road surface " this ultimate principle.Existing portable pendulum tester adopts rubber friction disc to contact and measure with road surface conventionally, so it exists the defect that detection speed is slow, impact property is little.Along with car speed is more and more faster, load-carrying is increasing, existing this portable pendulum tester can not meet the demand of in-site measurement.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, and the high speed swinging friction coefficient that a kind of measuring speed is fast, shaking moment is large proving installation is provided.
The purpose of this utility model realizes by following technological means:
A high speed swinging friction coefficient proving installation, is characterized in that: comprise frame, mount pad, fork, ram hammer, dolly and track, the upper end of mount pad is arranged in frame, the lower end hinge dress fork of mount pad, and ram hammer is installed in the lower end of this fork; Dolly consists of car body, wheel and friction pulley, wheel is arranged on car body lower end, and wheel is put in orbit, and this track is arranged on the ground of mount pad below, on the tie-beam of dolly, rotating shaft is installed, a friction pulley consistent with wheel traffic direction of coaxial installation in this rotating shaft.
And main shaft is installed in the lower end of described mount pad, universal shaft bearing of coaxial package on this main shaft, the upper end of fork is arranged in the made threaded hole in this universal shaft bearing bottom surface.
And the outside surface of described ram hammer sidewall is made a crotch.
And a baffle plate is all installed in the outside at the two ends, left and right of described dolly car body, a vertical top-fastening rod is all installed on each baffle plate.
And the diameter of described friction pulley is 240mm.
Advantage of the present utility model and good effect are:
1, this device is mainly comprised of pendulous device and sliding machine, and friction pulley is installed on dolly, and the impact by pendulous device promotes dolly advances, and the distance of advancing according to dolly can record the friction factor on road surface.This device adopts friction pulley instead of rubber friction disc, and adopts the measuring method of pendulous device impact-sliding dolly, makes measuring speed improve 4-5 doubly, impact energy (shaking moment) improves 40-50 doubly, has met at a high speed, the demand at large load measurement scene.
2, between each parts of this device, dismounting is easy, for transportation and storage etc. provide convenience, is convenient to go out detect and uses.
3, the utility model is a kind of reasonable in design, simple in structure, easy to use, practical high speed swinging friction coefficient proving installation, use this device can improve measuring speed and impact energy, therefore the occasion that this device is adapted at speed and impact energy to have relatively high expectations is used, and is particularly useful for airfield runway, highway etc.
