Problems solved by technology

Therefore, every time a point is measured, the telescopic rod must perform two actions of loosening→stretching→locking and loosening→shrinking→locking, which is very inconvenient

Embodiment

[0037] Take the inspection project of measuring the subway station project as an example. This project needs to measure the ground settlement around the construction site. There are 30 to 40 measurement points for a closure (one circle).

[0038] When actually measuring, first stand the ruler upright at the measuring point, then open the universal joint connecting the horizontal telescopic rod to the left, and then loosen the two telescopic rods, the horizontal rod faces down to the left, and the longitudinal rod faces back and down, respectively. Stretch it at an angle of about 45° until it hits the ground, and then lock it. After the measurement is completed, slightly lift the horizontal bar on the left, and at the same time pull the universal joint back to its original position, so that the two support bars return to the vertical side-by-side state, then hold the ruler in one hand and the two support bars in the other , carry the leveling rod on your shoulders, and you can ...

Abstract

The invention relates to the technical field of leveling staff, and specifically to a universal telescoping brace rod for leveling staff and a method. The universal telescoping brace rod comprises leveling staff, and is characterized in that: a main body (1) of a connecting piece is of a cylinder structure; one end of the main body is provided with a projecting block (2); the upper part of the projecting block is connected with a male catch connecting piece (3) which is inserted into a female catch (15) at the center of the leveling staff (14); the other end of the main body is connected withone end of a first telescoping brace rod support (7); a male tenon (8) is provided at the left of the upper side of the main body and inserted into a horizontal slotted hole (10) at one end of a universal joint body (9), the other end of the universal joint body is connected with one end of a second telescoping brace rod support (13). When the universal telescoping brace rod is used, the levelingstaff is erected at a measuring point, a universal joint is pulled open leftwards, and telescoping brace rods are respectively stretched and locked when the telescoping brace rods fall to the ground;after measuring is finished, a second telescoping brace rod is lifted up slightly, and the universal joint is pulled backwards to its original location, which enables the two telescoping brace rods to be vertical and parallel again. The universal telescoping brace rod provided in the invention can rotate at every direction and is convenient for actual utilization.

Description

[technical field] [0001] The invention relates to the technical field of leveling scales, in particular to a leveling scale universal telescopic strut and a method thereof. [Background technique] [0002] Leveling, also known as "geometric leveling", is a method of measuring the height difference between two points on the ground with a level and a leveling rod. Place a level between two points on the ground, observe the leveling rod erected on the two points, and calculate the height difference between the two points according to the reading on the ruler. [0003] Existing leveling rods are supported by surveyors with their hands to ensure the vertical state of the leveling rod body. Long-term support will cause fatigue to the surveyors. Coupled with the influence of the objective weather environment in outdoor operations, it is difficult to maintain the stability of the ruler body. , leading to measurement errors. [0004] CN201803726 discloses a telescopic strut for a le...
