Description

Road grade rod for engineering supervision

Technical Field

The application relates to the technical field of road detection devices, in particular to a road slope ruler for engineering supervision.

Background

The slope rule is a kind of graphic curve rule for determining the corresponding ground slope or its inverse process according to the parallel distance of the contour lines on the topographic map. Road construction manages and uses grade rod, is mainly used for measuring urban road's slope size, through the slope measurement to urban road, can carry out reasonable protection and safety guarantee to urban road.

At present, the chinese utility model patent with the publication number CN208505294U discloses a slope scale for highway engineering, which comprises an aluminum alloy ruler with the length of 1m-1.5m, a rectangular slope protractor is fixedly arranged at the middle position of the ruler, a gravity line hammer is arranged by taking a corner point above the slope protractor as the center of a circle, a sector marking disc with the diameter of 0.3m-0.35m is arranged in the middle of the slope protractor, and a scale value is arranged on the sector marking disc. When the ruler is used, the ruler is placed on the slope surface, the gravity plumb bob naturally droops, and the position of the gravity plumb bob coinciding with the scales of the protractor is the measured slope gradient. However, the slope protractor in the above scheme is fixedly installed on the straight ruler and is not easy to disassemble, and the length of the straight ruler is as long as 1m-1.5m, so that the slope protractor is very inconvenient to carry.

With respect to the related art in the above, the inventors consider that there is a drawback that the carrying of the gradiometer is extremely inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to facilitate the carrying of the slope ruler, the application provides a road slope ruler for engineering supervision.

The application provides a road slope chi for engineering supervision adopts following technical scheme:

the utility model provides a road grade rod is used in engineering supervision, includes protractor and scale, the scale includes mutual articulated canned paragraph and activity section, canned paragraph with all set up the groove of sliding with both terminal surface intercommunication that are close to each other on the top surface of activity section, the protractor slide set up in slide the inslot, be equipped with on the scale and be used for fixing the locating component of protractor.

By adopting the technical scheme, when the measuring device is used, the protractor is firstly placed in the sliding groove of the fixed section, then the movable section is rotated to pull the graduated scale open, then the protractor is pushed into the sliding groove of the movable section to be positioned at the connecting position of the fixed section and the movable section, the positioning assembly is adjusted to fix the protractor on the graduated scale, and finally the graduated scale is placed on the slope surface to carry out measurement; after the use finishes, adjust locating component and take off the protractor, then rotate the movable section and make the scale fifty percent discount to this dismantlement and the accomodating that realizes the grade rod has portable's effect.

Optionally, the first pivot of fixedly connected with in the canned paragraph, wear out the tip of first pivot the canned paragraph, fixedly connected with second pivot in the movable section, wear out the tip of second pivot the movable section, the canned paragraph with the hookup location of canned paragraph is equipped with the connecting piece, the connecting piece with first pivot reaches the second pivot is all rotated and is connected, just the canned paragraph is close to the corner position of first pivot reaches the movable section is close to the corner position of second pivot all is the arc transition.

Through adopting above-mentioned technical scheme, first pivot, the cooperation of second pivot and connecting piece, fixed section and activity section's articulated has been realized, at the in-process that the scale propped open, the activity section rotates along the arc transition face of fixed section, straighten until the scale, the terminal surface of activity section and the terminal surface laminating of fixed section this moment, and bottom surface between them flushes, the effect of flare-outing of scale has been strengthened, make the slope chi at the measuring in-process, the bottom surface of scale can with domatic laminating, thereby the measuring effect of slope chi has been ensured.

Optionally, the lateral wall that the canned paragraph is close to its both ends is gone up and is rotated respectively and is connected with interior joint piece and outer joint piece, interior joint piece with all seted up the draw-in groove on the outer joint piece, on the lateral wall that the movable segment is close to its both ends respectively fixedly connected with interior joint post and outer joint post, interior joint post with interior joint piece joint, outer joint post with outer joint piece joint.

By adopting the technical scheme, after the graduated scale is straightened, the inner clamping sheet is rotated to be clamped on the inner clamping column, and the inner clamping sheet forms a support at the connecting position of the fixed section and the movable section, so that the fixed section and the movable section are effectively prevented from rotating relatively, and the stability of the graduated scale during straightening is improved; after the scale fifty percent discount, rotate outer joint piece and make its card on outer joint post to this is fixed movable section and canned paragraph, stability when having improved the scale fifty percent discount scatters when preventing to carry.
