Description
Technical field:
The utility model relates to a kind of automated test device of measuring pavement skid resistance condition, and road surface transverse force measuring friction coefficient device particularly is used for the mensuration of highway pavement transverse force friction co-efficient value.
Background technology:
The road surface cornering ratio is the important technology index that characterizes pavement skid resistance condition, be the big event that delivery receiving acceptance and pavement quality evaluation and maintenance management must detect, and road surface cornering ratio determinator is a key component of measuring the high-efficient automatic testing apparatus of pavement skid resistance condition.At present, two kinds of ways of the general employing of the test of surface friction coefficient: a kind of method is that artificial portable pendulum tester is surveyed the pendulum value, and this method is used commonplace, but testing efficiency is low, and exists than mistake; Second method is to adopt the complex apparatus test, but costs an arm and a leg, and the cost height is not easy to wide popularization and application.
The utility model content:
The utility model purpose provides a kind of road surface transverse force measuring friction coefficient device, effectively reduces cost, improves testing efficiency and accuracy, and is easy to utilize, solves the problems referred to above that background technology exists.
Technical solutions of the utility model are: road surface transverse force measuring friction coefficient device comprises measurement bay, elevating mechanism, guide rail, balancing weight, measuring wheel, sensor, elevating mechanism and track are arranged on the measurement bay, measuring wheel is arranged on the balancing weight, balancing weight and guide rail, sensor is arranged on the measuring wheel.
The utility model is installed on the special-purpose vehicle, and every this device of special-purpose vehicle installation two covers, is used for measuring vehicle revolver, right transverse force friction co-efficient value of taking turns simultaneously.Measurement bay is installed on the special-purpose vehicle both sides, and between vehicle front-wheel and trailing wheel.Measurement bay self plane and vehicle heading keeping parallelism.
Said guide rail is the guide pillar of cylindrical shape preferably, is installed on the measurement bay each one of both sides.Balancing weight and guide pillar slide and mate, and are free to slide on guide pillar.Measuring wheel is installed on the balancing weight, and the measuring wheel right-hand member is connected on the balancing weight with articulated form, and the measuring wheel left end is connected with articulated form by the sensor two ends respectively with balancing weight, and measuring wheel and measurement bay self plane becomes angle 1030 degree.Elevating mechanism is installed on the measurement bay, and the elevating mechanism lower end is connected on the balancing weight with relocatable form, is used to control the rising or the decline of balancing weight.Elevating mechanism is public equipment, for example, and the elevating mechanism that motor, reductor etc. are formed etc.

Description of drawings:
Fig. 1 is the utility model example structure synoptic diagram.
Fig. 2 is the utility model embodiment plan structure synoptic diagram.
Among the figure: balancing weight 1, guide pillar 2, measurement bay 3, elevating mechanism 4, measuring wheel 5, sensor 6.
Embodiment:
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Road surface transverse force measuring friction coefficient device comprises measurement bay 3, elevating mechanism 4, guide rail, balancing weight 1, measuring wheel 5, sensor 6, elevating mechanism and track are arranged on the measurement bay, measuring wheel is arranged on the balancing weight, balancing weight and guide rail, and sensor is arranged on the measuring wheel.Guide rail is the guide pillar 2 of cylindrical shape, is installed on the measurement bay each one of both sides.Balancing weight 1 slides with guide pillar 2 and mates, and is free to slide on guide pillar.Measuring wheel 5 is installed on the balancing weight, and the measuring wheel right-hand member is connected on the balancing weight 1 with articulated form, and measuring wheel 5 left ends are connected with articulated form by sensor 6 two ends respectively with balancing weight 1, and measuring wheel and measurement bay self plane becomes angle 20 degree.Elevating mechanism is public, is installed on the measurement bay, and the elevating mechanism lower end is connected on the balancing weight with relocatable form, is used to control the rising or the decline of balancing weight.
The utility model principle of work is: elevating mechanism 4 control balancing weights 1, measuring wheel 5, sensor 6 descend, make measuring wheel 5 contact highway pavements, till balancing weight 1 total weight all acted on the measuring wheel 5, at this moment, elevating mechanism 4 lower ends were to balancing weight 1 no acting force.The chassis vehicle that road surface transverse force measuring friction coefficient mechanism is installed speed in accordance with regulations travels, because measuring wheel 5 and measurement bay 3 self plane becomes angle 20 to spend, promptly becomes angle 20 to spend with vehicle heading.Therefore measuring wheel 5 rotates and produces sliding friction with highway pavement in the vehicle ' process, and its friction force acts on the sensor 6, make sensor 6 with friction force with electrical signal collection and be transported to data handling machine.When detecting end, make the chassis vehicle that road surface transverse force measuring friction coefficient mechanism is installed stop to travel, make balancing weight 1, measuring wheel 5, sensor 6 rise to assigned position and get final product by elevating mechanism 4 controls.
