Description
Technical field:
The utility model relates to a kind of checkout equipment that detects the highway pavement rebound deflection value, belongs to highway road conditions checkout equipment technical field.
Background technology:
What detection road surface rebound deflection value generally adopted at present is traditional Beckman beam mensuration, testing stand was mentioned and is put down by the staff is manual when this method was measured, so need 8-10 people's operation, and labour intensity is big, speed is slow, work efficiency is low, safe coefficient is low, usually only record rebound deflection value, do not reflect the shape of deflection basin.In addition, the Beckman beam is measured static load method of testing owned by France, does not reflect the dynamic characteristics of road structure under the driving load action.
Through the literature search of institute of Yunnan Province scientific-technical information, do not find the open report identical with the utility model.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and the checkout equipment of a kind of practicality, reliable, efficient, safe detection highway pavement rebound deflection value is provided.
The utility model by measuring vehicle (1), place measuring vehicle (1) afterbody crossbeam both sides servo control mechanism (2), place between the wheel of both sides, measuring vehicle (1) back and the testing stand (3), hydraulic unit and the control system that are connected with servo control mechanism (2) are formed; Wherein:
The middle part of measuring vehicle (1) is the workplace of a sealing, and workplace is built-in with generator (4), Hydraulic Station (5), workbench (6), electric control box (7), has transom and door (8) on the two sides of workplace and the back; The rear portion of measuring vehicle (1) is a semiclosed workplace, and its afterbody crossbeam dual-side is used to put servo control mechanism (2);
Can be in the telescopic oscillating formula servo control mechanism (2) of three directions motion expansion bracket (10) formation by the base that is fixed on the vehicle afterbody (9), steel cable hoisting mechanism (11), the parallelogram sturcutre that links to each other with steel cable hoisting mechanism (11) with base (9) respectively;
The control system of checkout equipment automation control and data acquisition process is by placing notebook microcomputer (host computer), electric control box (7) on the workbench (6), placing programmable controller and software in the electric control box to constitute;
Hydraulic unit is made of Hydraulic Station (5), deflection hydraulic cylinder (14), the lifting hydraulic cylinder (12) that is connected with base (9), the vertical hydraulic cylinder (13) that is connected with expansion bracket (10), the folding and unfolding hydraulic cylinder (15) that is connected with steel cable hoisting mechanism (11);
By servo control mechanism servo (2) to point, the testing stand (3) that promotes and fall lever-type structure for perforate on it, an end of testing stand (3) be equipped with have high-resolution, the digital micrometer of high response speed.
Servo control mechanism of the present utility model and testing stand are self-control, and it is that combination is bought in market or the part improvement forms in parts.
The utility model is directly measured the resilience change curve under the actual traffic load effect, more can reflect the genuine property of the flexure of road surface under the vehicle operating condition or roadbed, possesses following characteristics:
1. structure is simple and direct, and car body is flexible, can adapt to mountain highway, can normally detect when bend.
2. with Beckman beam detection method good correlation is arranged, unmanned measure error for the factor introducing.
3. but road pavement is carried out the measurement of highly dense point, draws the detailed intensity distribution in whole piece road surface.
4. the measuring point spacing can be at 10m-1000m with interior any setting.
5. can measure springback process change curve (deflection basin).
6. the staff is few, and except that the driver, operating personnel only need 1-2 people.
7. be particularly suitable for carrying out large-area flexure investigation.
8. the detection scene need not suspend traffic, and is safe.

The specific embodiment:
Embodiment was made of following cyclic process when the utility model was used to detect the highway pavement rebound deflection value:
Process to be measured: monitoring measuring point distance, the speed of a motor vehicle, suitable apart from the time send reduce-speed sign and give the driver, control vehicle (1) is decelerated to low cruise.
To point process: monitoring measuring point distance, the speed of a motor vehicle, servo control mechanism (2) swing the operation contraposition forward, and the lateral adjustments deflection makes testing stand (3) accurately insert the double rear wheel group to take turns in the crack.Right to test point, steel cable hoisting mechanism (11) puts down testing stand (3).Vehicle (1) low cruise.
Rotating detection process: the monitoring speed of a motor vehicle, servo control mechanism (2) the reverse constant speed servo-actuated of the seam tracking through weaving torch speed of a motor vehicle backward, it is static that testing stand (3) keeps on the road surface, detects flexure data, road table temperature, air themperature, vehicle (1) low cruise.The detection of data is by placing notebook microcomputer (host computer), programmable controller, electric control box (7) and the software on the workbench (6), and hydraulic unit carries out automation control and data acquisition process.
Motion process: steel cable hoisting mechanism (11) is mentioned testing stand (3), and servo control mechanism (2) returns initial position, sends starting signal and gives the driver, and control vehicle (1) gives it the gun, to next test point motion.
The utility model is surveyed application on many highways such as the big speedway of Yunnan Province Chu, all obtain comparatively desirable effect.
The utility model is by expert appraisal, and consistent to think that this equipment has every functional, has advantages such as practicality, reliable, efficient, safety.
