Leveling rod inclination correcting device

Abstract

The invention discloses a leveling rod inclination correcting device, and belongs to the technical field of leveling rod correcting devices. The leveling rod correcting device of the correcting devicecomprises a correcting base, a first correcting part is arranged on the correcting base; a height-adjustable connecting part is also arranged on the correcting base; a second correcting part is arranged at the top of the connecting part; an optical signal receiver of the ruler inclination detection device is arranged in the protective rear cover; the disc is fixed to a front opening of the protective rear cover, the pointer is hinged to the circle center of the disc through a hinge shaft, the upper end of the pointer is connected with the leveling rod through a connecting rod, the lower end of the pointer is connected with the plumb bob through a fine line, and a light-transmitting hole is further formed in the disc and shielded by the pointer when the pointer is perpendicular to the light-transmitting hole. According to the correction device, the perpendicularity of the leveling rod is adjusted through the deviation angle of the pointer on the disc, the leveling rod is vertical afterthe pointer is completely vertical, and the correction device can be used for self-correction before measurement and can also be used for measurement and detection.

Description

technical field [0001] The invention relates to the technical field of leveling rod correction devices, in particular to a correction device for leveling rod inclination. Background technique [0002] The leveling rod is a ruler used for leveling measurement. It is made of high-quality wood, fiberglass, aluminum alloy and other materials. A circular level device should be attached to the body of the precision leveling rod, so that the person holding the ruler can keep the leveling rod at vertical position. If the inclination of the leveling rod is not in a vertical state, and the inclination of the leveling rod is large, it is easy to judge with the naked eye, but when the inclination of the leveling rod is small, it is difficult to judge with the naked eye, even if the inclination is small, it will affect the measurement accuracy of the leveling rod. Therefore, it is necessary to detect the tilt state of the leveling rod, and correct it when tilt occurs. Contents of the ...
