Description
Technical Field
The utility model relates to a check out test set technical field, more specifically say, relate to a detect road flatness device.
Background
The pavement evenness refers to the deviation value of the longitudinal concave-convex amount of the pavement surface, is an important index in pavement evaluation and pavement construction acceptance, and mainly reflects the evenness of a pavement longitudinal section profile curve. When the profile curve of the longitudinal section of the pavement is relatively smooth, the pavement is relatively flat or the flatness is relatively good, otherwise, the flatness is relatively poor, and the good pavement requires good flatness.
In the prior art, a section method is generally adopted for measuring the pavement evenness, the pavement evenness is evaluated by detecting the high and low distortion of a longitudinal section of a road, a folded three-meter straight ruler and a wedge-shaped filler gauge (generally a triangular filler gauge) are adopted for measuring, firstly, the three-meter straight ruler is arranged on the pavement at a test place, the gap condition between the bottom surface of the three-meter straight ruler and the pavement is visually observed, the position of the maximum gap is determined, the filler gauge is plugged in, and the height value of the maximum gap is measured. By adopting the method and the measuring device, firstly, the real maximum gap position can be determined by measuring for many times, the detection period is longer, in addition, the vertical height from the gap to the edge of the ruler is the vertical distance from the road surface to the bottom surface of the ruler when the constructor observes by naked eyes and the feeler gauge measures the numerical value, and the accuracy is not good enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a detect road flatness device, the device can once only read the clearance distance of a plurality of positions department in succession, conveniently confirms maximum clearance distance, reduces measurement personnel's the amount of labour, improves detection work efficiency, can also guarantee the detection accuracy.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides a detect road surface roughness device, includes three meters rulers and percentage table, three meters rulers on be equipped with the spill sliding block, spill sliding block sliding suit in three meters rulers tops, spill sliding block and three meters ruler contact position between be equipped with the slide, slide top and the inboard welded fastening of spill sliding block, spill sliding block one end outside be equipped with about two rectangle limiting plates, the rectangle limiting plate between be fixed with the elastic fixation area, the inside fixed percentage table of elastic fixation area, spill sliding block other end below be the L shaped plate of inside extension, L shaped plate upper surface be equipped with the vertical pivot of a plurality of, vertical pivot on all be equipped with a pulley, the pulley slide in three meters ruler sides.
Furthermore, the height of the concave sliding block is two thirds of the height of a three-meter ruler.
Furthermore, the concave sliding block transversely slides above the three-meter ruler through the sliding piece and the pulley.
Compared with the prior art, the utility model has the advantages that:
the utility model discloses in combine the percentage table through slide mechanism, carry out disposable measurement to the perpendicular distance on triangle ruler bottom surface and road surface, can once only read the clearance distance of a plurality of positions department in succession, conveniently confirm maximum clearance distance, reduce measurement personnel's the amount of labour, improve detection work efficiency, can also guarantee the detection accuracy.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the utility model easy to understand and understand, the utility model is further explained by combining with the specific figures.
As shown in fig. 1 and 2, a road surface flatness detection device comprises a three-meter ruler 1 and a dial indicator, a concave sliding block 2 is arranged on the three-meter ruler 1, the concave sliding block 2 is slidably sleeved above the three-meter ruler 1, a sliding sheet 3 is arranged between the contact position of the concave sliding block 2 and the three-meter ruler 1, the upper side of the sliding sheet 3 is fixedly welded with the inner side of the concave sliding block 2, a left rectangular limiting plate 4 and a right rectangular limiting plate 4 are arranged on the outer side of one end of the concave sliding block 2, an elastic fixing belt 5 is fixed between the rectangular limiting plates 4, the dial indicator is fixed inside the elastic fixing belt 5, an L-shaped plate extending inwards is arranged below the other end of the concave sliding block 2, a plurality of vertical rotating shafts 6 are arranged on the upper surface of the L-shaped plate, a pulley 7 is arranged on each vertical rotating shaft 6, the pulley 7 slides on the side surface of the three-meter ruler 1, the height of the.
When in actual measurement, firstly the three-meter straight scale 1 is opened and placed on the road surface of a test place, the position is found through the air level, after the three-meter straight scale is placed, the device is assembled above the three-meter ruler to ensure that the concave sliding block 2 can normally slide above the three-meter ruler 1, then the elastic fixing belt 5 is pulled open, a dial indicator is arranged between the rectangular limit plates 4, the measuring end below the dial indicator is vertically contacted with the ground right below, then one hand holds the dial indicator, the other hand pushes the concave sliding block 2 to slide on the three-meter ruler 1, the other person observes and records the numerical value on the dial indicator, measures the height numerical value of the maximum gap of the dial indicator and provides data for subsequent detection, wherein rectangle limiting plate 4 is spacing about going on the percentage table, avoids the excessive slope of percentage table, and the stability that concave sliding block 2 removed is guaranteed to pulley 7 and slider 3, improves detection accuracy.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
