Description
Technical field:
The utility model relates to a kind of checkout equipment that detects the highway pavement friction factor, belongs to highway road conditions checkout equipment technical field.
Background technology:
What the detection surface friction coefficient generally adopted at present is traditional portable pendulum tester method, and this method is a manual measurement, often move, settle the adjustment portable pendulum tester, and this method labour intensity is big, speed is slow, work efficiency is low.
For the fast detecting surface friction coefficient; Dragging when testing wheel rotates with mechanical means; Produce certain smooth (tire with the road surface sliding friction takes place, locking fully) when imposing additional drag testing wheel is rolled on the road surface to it again, the resistance that advances through the detection testing wheel and the vertical gravity of wheel promptly get surface friction coefficient; Because of the frictional resistance direction is the vertical of road, the numerical value of surveying is the vertical friction factor in road surface.This method of testing needs cloth spill certain thickness moisture film in testing wheel the place ahead when testing, the worst situation of pavement skid resistance condition when simulation is rained, so need carry the water of q.s during testing.
Vertically the coefficient of friction method also is widely used in China, and brake type, clearance-type, continous way are arranged, and its version is little towed vehicle formula; Because this test trailer does not have the water storage tank of ability and q.s voluntarily; Need carry the vehicle towed of enough water yields, and supply with water, electric power, have the tired connectivity problem of frequency of water, electricity; And volume, weight are all very big, in transportation, not too convenient when using.
Summary of the invention:
The purpose of the utility model is to overcome the deficiency of prior art and use, and a kind of checkout equipment of efficient, practical and convenient detection highway pavement friction factor is provided.
The utility model by double cab light truck (1), through base (4) be installed in vehicle-mounted suspension resistance measurement device (5) that angular transducer is housed on the double cab light truck (1) its, place 3500L water tank (2) in double cab light truck (1) container,, the computer and the controller (3) that are installed in the double cab rear space are formed.Wherein:
Vehicle-mounted suspension resistance measurement device (5) is by the rotary lifting-type testing wheel (6) that can pack up; Place the inner torque sensor (7) of rotary lifting-type testing wheel rotating shaft shell (11) that to pack up; Electromagnetic hysteresis detent (8); The chain gearing (9) that one end is connected with electromagnetic hysteresis detent (8), the other end is connected with torque sensor (7), place electromagnetic hysteresis detent (8) and the rotary lifting-type testing wheel (6) that can pack up between after drag cantilever rocking bar (10), and testing wheel rotating shaft shell (11) form.
The part parts of the utility model adopt market to buy product, the part parts adopt the material of market purchase to press the conventional method preparation.Wherein: computer and controller (3) and function software are market and buy.
The advantage of the utility model is: automaticity is high; Except that feed-tank added water, all the other operations were by computer control, and labour intensity is low, and is easy to use; Car body is flexible, and test process is quick.

It is following that the utility model is used for the embodiment of the vertical friction factor in continuous detecting road surface:
Set-up procedure: in water storage tank 2, add water; Mobile test car to testing highway starting point; Start computer and controller 3, put down the testing wheel 6 of resistance measurement device 5 automatically and tyre surface is freely landed, the angle of inclination of the angular transducer monitoring resistance measurement device 5 on the proving installation 5; By the height of the carbody of computer calculating light truck, its controlled quentity controlled variable transfers to the height that base 4 electric pushrods are adjusted base automatically.
Rotating detection process: double cab light truck 1; Computer and controller 3 follow procedures spill certain thickness moisture film at testing wheel 6 the place ahead cloth, and monitor range ability, the speed of a motor vehicle, and control electromagnetic hysteresis detent 8 produces corresponding damping force; Transmit damping force through chain gearing 9; Make testing wheel 6 produce certain slippage with respect to the road surface, torque sensor 7 calculates friction factor by the frictional resistance moment data that every meter one-time continuous collecting test wheel 6 receives.In the rotating detection process; The height of the carbody that places the angular transducer monitoring light truck on the resistance measurement device 5 to cause because of institute's water carrying capacity changes changes; Its variable quantity transfers to the height that base 4 electric pushrods are adjusted base automatically, makes the angle of inclination of resistance measurement device 5 remain unanimity.
Terminal procedure: ramp to stop, computer and controller 3 follow procedures stop data collection, and close the watering switch, close electromagnetic hysteresis detent 8, mention the testing wheel 6 of resistance measurement device 5 automatically, make tyre surface liftoff.
Practical application shows that the utility model reaches designing requirement fully.
