When holding the push rod to push the trolley to move from one end of the straight scale guide rail to the other end of the straight scale guide rail, a person can observe measuring results while walking to ensure that problems are conveniently found in time. The portable pavement profilometer disclosed by the utility model is mainly used for the field detection and the quality control during the pavement construction.
Description
Technical field
The utility model belongs to field of measuring technique, relates to a kind of portable road wheel profile measuring apparatus device.
Background technology
Uneven road makes vehicle produce running resistance and vibration under steam, can directly influence ride comfort, riding comfort and the serviceable life of vehicle when serious, so the rough detection of road pavement profile is very necessary.(the patent No.: 96234713.2) that our unit had once been invented a kind of " ruler type digital display highway smoothness measuring equipment "; And passed through the assessment of result No. the 094th, word 1996 (friendship section become mirror) of Ministry of Communications, it can overcome three meters ruler mensuration work efficiency of tradition low, receive human factor to influence defectives such as big.But it can't measure road surface lateral contours such as rut or side slope.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned background technology, increases road surface lateral contour measurement function, for highway and urban road, airfield runway provide a kind of easy, multifunction road profile measurement instrument accurately.
The purpose of the utility model realizes with the following methods.A kind of portable road wheel profile measuring apparatus is made up of parts such as ruler guide rail, leg, dolly, push rod and digital display instruments.Leg and screw mandrel adopt interference fit, support and fixing ruler guide rail through nuts and washers, on the ruler guide rail air level are installed, and the height of rotating nut scalable ruler guide rail is also observed air level and come the levelling working face of guide rail; The dolly side is equipped with the digital type linear displacement transducer of a measuring vertical distance, and a digital angular displacement sensor of measuring horizontal range is installed on the dolly axletree; Digital display instrument is installed on the dolly push rod, LCD, power switch is arranged on the panel of digital display instrument, the reset key that resets, show maximum height of the profile difference key, show the contour curve key.Hold push rod and promote dolly can be realized the road surface profile to other end motion from an end of ruler guide rail measurement.
The characteristics or the effect of the utility model are: 1) this road surface contourgraph is a kind of small-sized static surveying instrument; Can show and vertically reach lateral route facial contour figure or parameter value; Can be used for the evaluation of surface evenness, rut and side slope; The scene that is mainly used in the pavement constructions such as highway and urban road, airfield runway is detected, and can in time pinpoint the problems and be convenient to quality control.2) this road surface contourgraph is simple in structure, and the ruler guide rail adopts the rectangle hollow aluminium alloy extrusions, is convenient to dismounting and carrying, adopts digital displacement transducer to be convenient to the microsystem signal Processing, and measuring accuracy is high.
Description of drawings
Accompanying drawing 1 is the total structure synoptic diagram of the utility model.Among the figure, 1-leg, 2-nut, 3-packing ring, 4-packing ring; The 5-nut, 6-screw mandrel, 7-air level, 8-dolly, 9-dolly wheel; The 10-linear displacement transducer, 11-roller, 12-push rod, 13-digital display instrument, 14-LCDs; 15-power switch, the 1 6-reset key that resets, 17-show maximum height of the profile difference key, and 18-shows contour curve key, 19-ruler guide rail.
Accompanying drawing 2 is the dolly wheel position cross-sectional view of the utility model.Among the figure, the digital angular displacement sensor of 20-, the articulated joint of 21-push rod, all the other numberings are identical with accompanying drawing 1.
Embodiment
Be described further with reference to the enforcement of accompanying drawing below the utility model.
Leg 1 adopts interference fit to tighten together with screw mandrel 6, is supporting ruler guide rail 19 through nut 2 and packing ring 3, and nut 5 is used for locking with packing ring 4, and right ends respectively has 1 air level 7 (observing when being convenient to leveling) on the workplace of ruler guide rail 19.Dolly 8 sides are equipped with the digital type linear displacement transducer 10 (digital display centimeter of band output interface) of a measuring vertical distance, and the measuring staff front end of sensor 10 has a roller 11 to roll neatly along the road surface.A digital angular displacement sensor 20 (optical disc) of measuring horizontal range is installed on 9 of the dolly wheels.Digital display instrument 13 is installed on the dolly push rod 12; Digital display instrument 13 is that equipment circuit, rechargeable battery, the IO interface of core formed by display panel, with the single-chip microcomputer; Display panel comprises: LCD 14, power switch 15, the reset key 16 that resets, demonstration maximum height of the profile difference key 17, demonstration contour curve key 18; Input interface is used for being connected with displacement transducer, and output interface is used for being connected with notebook computer with portable printer.Push rod 12 is connected through push rod articulated joint 21 with dolly 8.
Before the measurement, earlier ruler guide rail 13 is transferred to proper height and furnishing level.During concrete operations, unclamp nut 5 earlier, rotating nut 2 is scalable ruler guide rail 19 distance overhead, and observes air level 7 and come levelling.After 19 leveling of ruler guide rail, fastening nut 5.
During measurement, shift dolly 8 end of ruler guide rail 19 onto, open the power switch 15 on the digital display instrument 13, by the reset key 16 that resets, this moment display digit " 0 " on LCDs 14; Hold push rod 12 then and promote dollies 8 and move to the other end, on LCDs 14, can dynamically show the instantaneous height value of road surface profile this moment from an end of ruler guide rail 19; Stop dolly 8 motions after waiting to arrive certain horizontal range, can check the result by demonstration maximum height of the profile difference key 17 or demonstration contour curve key 18 as required this moment.Measure powered-down switch 15 when finishing.Because digital display instrument 13 is installed on the dolly push rod 12 near near the handgrip, operating personnel can see measurement result while walking, and are convenient in time pinpoint the problems.
