Abstract
The utility model relates to a full-automatic checking and testing instrument for leveling degree of highways. The full-automatic checking and testing instrument is mainly composed of a guide rail, a checking and testing sensing device and a control box. Roadway uneven signals, by a measuring wheel always on the measuring sensing device contacts ground, are sent to the control box for processing and displaying after converted into RS232c codes by a capacitor grid displacement sensing device. The utility model has rapid measuring speed, high precision and low labor intensity, and is an ideal full-automatic checking and testing instrument for leveling degree of highways.
Description
The utility model relates to the roughness index detecting instrument in a kind of highway, airport, city and factories and mines road construction, the maintenance processes.
Highway, airport, city and factories and mines road planeness detect used tool at present, generally be three meters rulers and steel ruler, during measurement, ruler be placed on the road surface to be measured, with the maximal clearance between eyes observation ruler and the ground, measure the concrete numerical value in this gap then with steel ruler.This method tests the speed low, low precision, and labour intensity is big, does not adapt to highroad industry quality inspection requirement.
The purpose of this utility model is to provide a kind of full-automatic highway testing flatness instrument fast, that precision is high that tests the speed.
The utility model is realized by following manner: it by guide rail, on guide rail reciprocating test sensing unit and accept the pulse signal of test sensing unit output and handle, show that result's control cabinet forms.The guide rail two ends can be provided with bearing, and test sensing unit can be made up of dolly, dolly transmission mechanism and the capacitive displacement transducer that is loaded on the dolly; Control cabinet can be made up of capacitive grid numeral display instrument and switch, charging device, battery.
The full-automatic highway testing flatness of the utility model instrument, it is fast to test the speed, and the precision height, only need be placed on the road surface to be measured, and operation control box just can directly show test results, and is a kind of desirable full-automatic highway testing flatness instrument.
Accompanying drawing has provided an embodiment of the present utility model;
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model test sensing unit structural representation;
Fig. 3 is that capacitive displacement transducer connects schematic diagram with meter wheel.
With reference to the accompanying drawings the utility model is described in further detail:
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model is had three meters long straight guide rails 1 of bearing by two ends, test sensing unit 2, control cabinet 3 is formed, test sensing unit 2 is by dolly 7, dolly transmission mechanism and the capacitive displacement transducer 5 that is loaded on the dolly are formed, dolly by micro machine 8 through reducing gear 9, driving dolly wheel 10 walks on guide rail 1, guide rail 1 cross section is a rectangle, capacitive displacement transducer 5 is loaded on dolly 7 left sides, meter wheel 6 moving up and down is equipped with in its lower end, meter wheel support 11 adopts thread connection capacitive displacement transducer 5 usefulness leads to connect with control cabinet 3 with capacitive displacement transducer 5, control cabinet 3 is by the capacitive grid numeral display instrument, battery, switch, charging device is formed, it provides power for test sensing unit 2, acceptance test sensing device 2; The RS232C sign indicating number of output is handled and the demonstration result by the capacitive grid numeral display instrument.
The concrete measurement of the utility model is performed such: guide rail 1 and test sensing unit 2 are placed on the ground, test sensing unit 2 places an end of guide rail 1, press the switch on the control cabinet 3, test sensing unit 2 uniform motion forward on guide rail 1, meter wheel 6 in the capacitive displacement transducer on it is with uneven the moving up and down (kiss the earth all the time) on ground, and movement value changes the RS232C sign indicating number into through capacitive displacement transducer processing trailing wheel and sends into the processing of control cabinet 3 content grid digital display instruments, shows.This capacitive displacement transducer and capacitive grid numeral display instrument are all selected the 25 type capacitive displacement transducers and the X type capacitive grid numeral display instrument of the First Academy of space flight and aviation portion exploitation for use.
