Abstract

The utility model relates to a direct-read high way arch degree and level degree measurer. A main scale which is connected by hinges and is conduplicate is arranged; the upper part of the rear ruler body is provided with an auxiliary ruler, a positioning top screw and an adjustable top screw for adjusting a level bubble to make one end of the auxiliary ruler compress a meter rod and move a meter pointer, the utility model has the advantages of small volume, light weight, direct reading and simple operation; the measuring precision can be up to more than 0.05 %; the direct-read high way arch degree and level degree measurer is suitable for measuring high way arch degree and level degree.

Description

Direct-read high way arch degree and level degree analyzer

The utility model relates to highway pavement camber and smooth measuring apparatus.

Measure at present the highway camber, mostly adopt level gauge or three meters rulers to add method such as tape measure and measure.The use level gauge is measured, need earlier the level gauge leveling, observe center, tested pile No. road scale height and curb place scale height again, try to achieve the road camber gradient of this pile No. again divided by 1/2nd values of width of roadway, need 2-3 people just can finish at least by calculating 2 discrepancy in elevation.Three meters rulers add the tape measure method: earlier three meters ruler one ends are placed the center, road surface, the other end is placed on curb and holds in the palm and make air level placed in the middle, use the height on tape measure chi end distance ground then, its height is exactly the camber value of this pile No. with the ratio of chi length, can not be less than two people during operation.

The said method operation all needs more than two people, and loaded down with trivial details effort, dyscalculia, and certainty of measurement is not high, makes mistakes easily, often brings many inconvenience to construction of the highway control final acceptance of construction.

The purpose of this utility model is: a kind of operation is provided, calculates easyly, volume is easy to carry about with one for a short time, direct-reading highway camber and rideograph that certainty of measurement is high.

The utility model be before folding be set connect after blade and the back blade doubling by the fixing main scale that forms of snap close; Back blade top is provided with the secondary chi that connects by secondary chi bearing; In secondary chi outer end the location jackscrew is set, adjustable jackscrew makes an end compaction table bar of secondary chi move indicator in order to adjust air level.

Bottom, two ends at main scale is provided with rotatable front support leg, rear leg.

It is little to the utlity model has volume, in light weight, easy to operate, direct-reading, certainty of measurement advantages of higher.

Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model;

Accompanying drawing 2 is plan structure schematic diagrames of the present utility model.

In the accompanying drawing: 2, spring; 3, steel ball; 4, U template hold-down screw; 6, U template; 7, bearing pin; 8, latch plate; 9, hex screw; 17, backplate hold-down screw; 18, backplate; 19, air level; 22, fishbolt; 23, table; 24, table protecting cover; 25, protecting cover bearing pin; 27, alignment pin; 28, main scale.

Before folding (12) connects after blade (13) and back blade (10) doubling by the fixing main scale (28) that forms of snap close (26), back blade (10) top is provided with the secondary chi (20) that connects by secondary chi bearing (21), secondary chi (20) outer end is provided with location jackscrew (16), and adjustable jackscrew (15) makes end compaction table (a 23) bar of secondary chi (20) move table (23) pin to adjust air level (19).The bottom, two ends of main scale (28) is provided with front support leg (14), the rear leg (1) of rotation.

During use, prop up fixedly snap close (26) of folding front and back blade (13), (10), with front and back leg (14), (1) Rotate 180 ° downwards, the other end of secondary chi (20) places the curb place vertically vertical with road, opening table protecting cover (24) adjustment jackscrew (15) makes the air level (19) in the secondary chi placed in the middle, the table look-up scale value of (23) pin indication of sight, this value is the camber value of tested pile No..

Front and back leg (14), (1) are rotated up 180 ° just becomes three meters rulers, just can measure surface evenness with the lower plane of blade.

Claims

1, a kind of direct-reading highway camber and rideograph, it comprises spring, steel ball, U template hold-down screw, U template, bearing pin, latch plate, hex screw, backplate hold-down screw, backplate, air level, fishbolt, table, table protecting cover, protecting cover bearing pin, alignment pin, folding hold-down screw, it is characterized in that: before folding is set connects after blade and the back blade doubling by the fixing main scale that forms of snap close; Back blade top is provided with the secondary chi that connects by secondary chi bearing, the location jackscrew is set in secondary chi outer end, adjustable jackscrew makes an end compaction table bar of secondary chi move indicator in order to adjust air level.
