Description

Auxiliary device for leveling rod

Technical Field

The utility model relates to a leveling device, especially an auxiliary device for levelling rod.

Background

In the prior art, the leveling instrument is used for measuring the elevation, which is an important measure for leveling, and a circular level device is attached to a ruler body matched with the precise leveling staff, so that a staff holding the ruler can stably keep the leveling staff at a vertical position during operation, and the staff is convenient to observe. Based on the use to measuring levelling rod, because factors such as environment and people are in the operation process for the levelling rod always can not put perpendicularly, thereby increased the unnecessary error when measuring, the long-time not only work load of holding up the chi personnel is big moreover, is difficult for straightening. The traditional correction method is that two theodolites or total stations are arranged on the leveling rod as the center in the direction that the sight lines mutually form 90 degrees, a corrector is under the command of two observers to keep the leveling rod vertical in the sight line direction of the two instruments, then a round leveling device correction screw on the leveling rod is adjusted to center the bubble, and thus the perpendicularity of the leveling rod can be completely corrected after being repeated for several times. The method needs to operate two theodolites or total stations in a certain space at the same time, and needs at least 3 calibration personnel to operate, so the calibration method is complicated, slow in speed, large in occupied space, difficult to operate and low in efficiency. And the measurement work often meets night work, and because night visibility is low, and the lighting condition is poor, the general leveling rod is difficult to meet the night measurement condition.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses an auxiliary device for levelling rod can make the levelling rod automatic vertical, and easy operation is convenient, and is efficient, and this auxiliary device has LED lamp area, is convenient for carry out the night work.

The utility model discloses a following technical scheme realizes:

an auxiliary device for a leveling rod comprises an upper supporting sleeve and a lower supporting sleeve which are sleeved together and are transparent, wherein a positioning bolt is arranged at an upper port of the lower supporting sleeve, and the upper supporting sleeve and the lower supporting sleeve are fixed together by the positioning bolt; the top of the upper supporting sleeve is detachably connected with a top cover, the center of the top cover is connected with a suspension wire, the lower end of the suspension wire is connected with a U-shaped fixing piece with a downward opening, fastening bolts for fixing a leveling rod are respectively arranged on two sides of the U-shaped fixing piece, and the front side and the rear side of the top of the U-shaped fixing piece are provided with scale marks; the lower part both sides of lower support cover articulate respectively has the telescopic link.

Furthermore, the tail ends of the positioning bolts and the tail ends of the fastening bolts are provided with anti-skid rubber pads.

Furthermore, the tail end of the telescopic rod is provided with a spine part.

Furthermore, a circle of LED lamp strip is respectively arranged on the inner side of the top cover of the upper supporting sleeve and the inner side of the bottom cover of the lower supporting sleeve.

Further, the cross section of the upper supporting sleeve and the lower supporting sleeve is rectangular, square or circular.

The beneficial effects of the utility model are that the leveling rod is fixed on the suspension wire at the center of the top cover of the upper supporting sleeve, the gravity action of the leveling rod can be utilized to make the leveling rod always in a vertical state, and the complicated steps of manual adjustment are reduced; the scale marks are arranged on the fixing piece, and the fastening bolts on the left side and the right side of the fixing piece can be adjusted according to the scale marks, so that the leveling rod is positioned at the midpoint of the suspension wire, and the leveling rod can be kept in a vertical state; when the environment with a larger gradient is met, the telescopic rod at the lower part of the lower supporting sleeve can be utilized to carry out rapid initial adjustment, and then the leveling rod is automatically in a vertical state under the action of gravity; the arrangement of the upper support sleeve and the lower support sleeve can ensure that the leveling rod is in a closed environment, thereby being not influenced by the wind force in the outside and ensuring that the leveling rod can not be interfered; the upper support sleeve and the lower support sleeve are sleeved together, and the length of the support sleeve can be freely adjusted so as to adapt to the sizes of different leveling rods; finally, the LED lamp strip can provide illumination for night measurement.
