Abstract
The utility model provides a digital subgrade evenness measuring instrument. Traditional three-meter ruler measuring methods have the defects of low measuring accuracy, complexity in operation, time waste and large amount of labor. The digital subgrade evenness measuring instrument comprises a horizontal guide rail (3), wherein the left end of the horizontal guide rail is connected with the upper end of a circular support (2); the lower end of the circular support is connected with a height adjusting knob (1); the horizontal guide rail passes through two pulleys (8); the two pulleys are connected with a sliding fixator (5); the sliding fixator is connected with a range finder (4); the right end of the horizontal guide rail is connected with the top end of an inverted T-shaped frame (6); a group of universal wheels (7) are arranged at the bottom end of the inverted T-shaped frame. The digital subgrade evenness measuring instrument is used for detecting the subgrade evenness.
Description
technical field:
the utility model relates to a kind of digitlization grading degree measuring instrument.
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.By road evenness, detect the planeness of road pavement and make evaluation, for policymaker provides important information, make policymaker make Optimal Decision-making for maintenance, the maintenance on road surface 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 surpasses 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 of road or repair not in place; Its two, mode of operation is complicated, 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.
utility model content:
the purpose of this utility model is to provide a kind of digitlization grading degree measuring instrument.
above-mentioned object realizes by following technical scheme:
a kind of digitlization grading degree measuring instrument, its composition comprises: horizontal guide rail, 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.
the beneficial effects of the utility model:
1, the utility model outmoded and not high measuring apparatus of accuracy before abandoning, new survey tool makes measurement result more accurate, avoids inaccurately causing the raising of the rehabilitation cost of road or repairing not in place because detecting.
, the utility model pulley 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.
, the utility model operating procedure simplifies more, easy association, 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.
, the utility model is adopted as aluminium alloy structure, avoids horizontal guide rail to deform, warpage.Guarantee the accuracy of testing result.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is accompanying drawing 1 left views.
the specific embodiment:
embodiment 1:
a kind of digitlization grading degree measuring instrument, its composition 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, 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:
according to the digitlization grading degree measuring instrument described in embodiment 1, described pulley, before detection, checks whether 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.
embodiment 3:
according to the digitlization grading degree measuring instrument described in embodiment 1 or 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, by described height adjustment knob, make horizontal guide rail two ends identical, the Level tune of digitlization grading degree measuring instrument completes.
embodiment 4:
according to the digitlization grading degree measuring instrument described in embodiment 1 or 2 or 3, described rangefinder moves on to the other end from one section, and height of observation changes maximum value, by the comparison with changing permissible value, realize and detect road in the height change value of certain distance, judge that whether road evenness is qualified.
Claims (1)
