Abstract
The invention relates to a digital roadbed flatness measuring apparatus and measuring method. The traditional 3-meter ruler measuring method is high in measurement accuracy, complicated in operation, time-wasting and high in working capacity. The digital roadbed flatness measuring apparatus comprises a horizontal guide rail (3), wherein the left end of the horizontal guide rail is connected with the upper end of a circular bracket (2); the lower end of the circular bracket is connected with a height adjustment knob (1); the horizontal guide rail passes through two groups of pulleys (8); the two groups of pulleys are connected with a sliding fixer (5); the sliding fixer is connected with a distance measuring meter (4); the right end of the horizontal guide rail is connected with the top end of an inverted T-shaped frame (6); and the bottom end of the inverted T-shaped frame is provided with a group of universal wheels (7). The invention is used for detecting roadbed flatness.
Description
technical field:
the present invention relates to a kind of digitlization grading degree measuring instrument and measuring method.
background technology:
surface evenness is one of the key technical indexes of evaluation pavement quality, and planeness affects road surface receive strength rationality, safety and comfort whether in the length in application life and Vehicle Driving Cycle process.Detect the planeness of road pavement by road evenness and make qualification, for policymaker provides important information, make policymaker make Optimal Decision-making for the maintenance on road surface, maintenance and the problem such as overhaul.On the other hand, the detection of surface evenness can provide the information of construction quality of pavement exactly, for pavement construction provides the objective indicator of a performance rating.Three meter ruler measuring methods for tradition, first, launch to be placed on road surface to be measured by 3m ruler; Secondly clearance gauge is inserted to the space, everywhere on 3m ruler and ground, recording distance value, relatively whether maximum range value exceedes permissible value, and evaluation planeness, judges whether to overhaul maintenance.But there is following shortcoming; One, traditional measuring accuracy is not high, detects inaccurately cause the raising of the rehabilitation cost to road or repair not in place; Its two, mode of operation complexity, conventional method allow the survey crew action of repetition of repeatedly bending, get off for a long time function of human body had to certain damage; Its three, artificial reading is easily slipped up, and produces error.
summary of the invention:
the object of this invention is to provide a kind of digitlization grading degree measuring instrument and measuring method.
above-mentioned object realizes by following technical scheme:
a kind of digitlization grading degree measuring instrument, its composition comprises: horizontal guide rail, it is characterized in that: described horizontal guide rail left end is connected with circular support upper end, described circular support lower end is connected with height adjustment knob, described horizontal guide rail is by two groups of pulleys, described two groups of pulleys with slide fixator and be connected, the described fixator that slides is connected with rangefinder, described horizontal guide rail right-hand member is connected with inverted T shape frame top, and described inverted T shape frame bottom has one group of universal wheel.
utilize a described digitlization grading degree measuring method, the method comprises the steps:
(1) described pulley, before detection, checks whether described pulley can be free to slide on described horizontal guide rail, and whether described horizontal guide rail without being out of shape, warpage, and whether described rangefinder can normally work;
(2) described digitlization grading degree measuring instrument is placed in the section braking that need to carry out planeness detection, described rangefinder is moved to described horizontal guide rail one end, measure the distance on ground, again rangefinder is moved on to the horizontal guide rail other end, make horizontal guide rail level by described height adjustment knob, the Level tune of realizing digitlization grading degree measuring instrument completes.
(3) described rangefinder moves on to the other end from one end, and height of observation changes maximum value, by with the comparison that changes permissible value, realize and detect the height change value of road at certain distance, judge that whether road evenness qualified.
beneficial effect of the present invention:
1, the present invention's measuring apparatus and measuring method outmoded and that accuracy is not high before abandoning, new survey tool and measuring method make measurement result more accurate, avoid inaccurately causing the raising of the rehabilitation cost to road or repairing not in place because detecting.
2, pulley of the present invention substitutes manual measurement, the more cheap hommization of mode of operation, detection method in the past causes people's action of repetition of repeatedly bending, and gets off for a long time function of human body is had to certain damage, and new detection method can free people from heavy manual labor.
3, operating procedure of the present invention is simplified more, easily association, and the measurement of distance is directly presented on rangefinder, more directly perceived, has avoided the error of artificial reading, and detection efficiency is improved greatly.
4, the present invention is adopted as aluminium alloy structure, avoids horizontal guide rail to deform, warpage.Ensure the accuracy of testing result.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is left views of accompanying drawing 1.
detailed description of the invention:
embodiment 1:
a kind of its composition of digitlization grading degree measuring instrument comprises: horizontal guide rail 3, described horizontal guide rail left end is connected with circular support 2 upper ends, described circular support lower end is connected with height adjustment knob 1, described horizontal guide rail is by two groups of pulleys 8, described two groups of pulleys with slide fixator 5 and be connected, the described fixator that slides is connected with rangefinder 4, and described horizontal guide rail right-hand member is connected with inverted T shape frame 6 tops, and described inverted T shape frame bottom has one group of universal wheel 7.
embodiment 2:
utilize the digitlization grading degree measuring method described in embodiment 1, the method comprises the steps:
(1) described pulley, before detection, checks whether described pulley can be free to slide on described horizontal guide rail, and whether described horizontal guide rail without being out of shape, warpage, and whether described rangefinder can normally work;
(2) described digitlization grading degree measuring instrument is placed in the section braking that need to carry out planeness detection, described rangefinder is moved to described horizontal guide rail one end, measure the distance on ground, again rangefinder is moved on to the horizontal guide rail other end, make horizontal guide rail level by described height adjustment knob, the Level tune of realizing digitlization grading degree measuring instrument completes;
(3) described rangefinder moves on to the other end from one end, and height of observation changes maximum value, by with the comparison that changes permissible value, realize and detect the height change value of road at certain distance, judge that whether road evenness qualified.
