Description

Multi-purpose road measuring ruler

The utility model relates to detect a kind of measurement mechanism of the relevant amount of road and similar place.

In constructing road,, adopt three meters rulers usually at present, cooperate clearance gauge to detect for guaranteeing surface evenness.Three meters rulers peg graft integral body mutually by three joint aluminum strip boxes, and the centre of chi is equipped with spirit-leveling instrument.As the asphalt concrete pavement after paving, be placed on the road surface with three meters long rulers, fill in gap between ruler and road surface with clearance gauge again, judge the flatness error size at this place according to the thickness of the clearance gauge of filling in.The deficiencies in the prior art part is: bother in the operation, use inconvenient, time-consuming bothersome; Detect and be difficult for accurately; Be that this chi does not possess other function again.

The purpose of this utility model is to avoid the deficiencies in the prior art part, and provide a kind of easy to use, detect accurately road and use the dip stick product more.

Can take following technical scheme to realize purpose.Flatness is installed on three meters rulers detects table, number percent horizontal wall inscription table and right angle gradient table; Flatness detection table is that the weight ratio device, number percent horizontal wall inscription table and the right angle gradient table that mainly are made of around fulcrum pointer and roller are level, the vertical balance devices that mainly is made of respectively around fulcrum indicator and heavy chain.Both made and can detect flatness, can measure the number percent transverse slope again, the right angle gradient etc. use dip stick more.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Road is used dip stick more, must adopt three meters rulers as carrier.This is the regulation of related standards for three meters length, as for its version, can peg graft central authorities whole, chi that spirit-leveling instrument is installed mutually by three joint aluminum strip boxes; Also can adopt other version as one sees fit.

The roughness measurement Table A should be the weight ratio device that mainly is made of around fulcrum pointer (4) and roller (7); It is installed in the interstitial segment of ruler to good; Fulcrum to the distance of ruler bottom surface should be much smaller than roller bottom wheel rim to fulcrum distance, as long as pavement roughness, have indentation, the roller end always freely is in pocket under action of gravity, and shows the error size of its irregularity degree by pointer.Same number percent horizontal wall inscription table B and right angle gradient table C should be level, the vertical balance devices that mainly is made of respectively around fulcrum indicator and weight; These two tables are installed in respectively in the both sides sections of ruler to good; No matter the chi body orientation of three meters rulers how, the indicator of number percent horizontal wall inscription table and weight always freely are in the horizontal equilibrium position, the indicator of right angle gradient table and weight always freely are in vertical position, get final product the numerical value of show percent transverse slope, the right angle gradient from dial plate.As for each table other zero, modular construction, the mode of combination, the form of installation etc. all can select as one sees fit.

In the illustrated example, it is roller (7) is installed in forked clamping plate (6) by axle (5) rear portion that flatness detects Table A, forked clamping plate (6) and pointer (4) linearly are fixedly connected on the both sides of main shaft (8), can be installed on relative to the main shaft that clamping plate freely rotate between the major and minor clamping plate (1,2), dial plate (3) at the pointer front end, be installed in the weight ratio device on the bottom plate.Number percent horizontal wall inscription table B is equipped with bipyramid end axle (14) on the indicator (11), be installed in the indicator rear portion, constitute weight by bolt by nut (12), spring (13), can be installed on by recessed end screw (15) relative to the bipyramid end axle that clamping plate freely rotate between major and minor clamping plate (9,16), dial plate (10) is installed on horizontal equilibrium device on the bottom plate at the indicator front end.Right angle gradient table C is on the arm of U-shaped indicator (18), is fixed with bipyramid end axle (21), weight (19) is equipped with in the bottom, can be installed on vertical balance device on the clamping plate (20) by recessed end screw (22) relative to bipyramid end axle that clamping plate freely rotate.These three kinds of tables all use clamping plate to fixedly connected with three meters ruler chi bodies.

In order to make observation more convenient, also can spirit-leveling instrument D be installed in the end of three meters rulers.

During use, this chi is placed on arbitrarily on the road surface, opens the wicket of ruler flatness detection table downside, roller contact road surface pocket can be read this indicated flatness error numerical value of pointer from dial plate, and this table minimum scale can be to the 0.5-0.2 millimeter.This chi laterally is placed on the transverse slope number percent number that to read this on the intact road surface of making from number percent horizontal wall inscription table.When needs were built the trench drain, the low slope, right angle of accomplishing up and down of curb exterior angle and ditch was placed on this chi on the slope and can reads gradient numerical value from right angle gradient table.

The relative prior art of the technical program has following advantage:

1, use is extremely convenient, saves time and saves trouble;

2, detection is accurate, rapid, the direct-reading structure, and precision improves;

3, integrate multiple function, one-object-many-purposes.
