Embodiment 1

[0026] Example 1: Combining Figure 1 to Figure 4 Illustrate the leveling device of the present invention, it comprises the scale 1 vertically standing on the chi pad 5, the level bubble 2 installed at the height 1m of the side of the scale 1, the slideway 4 arranged longitudinally along the scale 1, and the slideway 4 that can be installed along the slideway 4 Relative to the sliding fixed bracket 3 , the fixed bracket 3 includes a sliding block 30 that is slidably matched with the slideway 4 , and a bracket leg that is bolted to the sliding block 30 . Above-mentioned ruler pad 5 is made by triangular cast iron block, and there is the hemisphere that protrudes in the center of the top, and three pointed corners are arranged in the bottom so that stretch into the soil, make it stable. During use, the ruler pad 5 is stepped on the ground, and the ruler 1 stands upright on the protruding hemispherical top. When the ruler 1 rotates direction, the elevation of the bottom of the ru...

Embodiment 2

[0033] Embodiment 2: Combination Figure 2 to Figure 4 Explain that the leveling device of the present invention is different from Embodiment 1 in that the above-mentioned slideway 4 is made of a U-shaped slide bar, and the cross section of the slideway 4 is widened, and the two ends of the slideway 4 are vertically fixed on the scale 1, the vertical part of the slideway 4 runs through the slide block 30 and is slidably fitted with the slide block 30, so that the slide block 30 can move stably relative to the slideway 4.

Embodiment 3

[0034] Example Three: Combining Figure 1 to Figure 4 The measuring method of the leveling measuring device of the present invention is described, and the steps are as follows:

[0035] S101: Stand the ruler 1 vertically on the ruler pad 5;

[0036] S102: According to the specific measurement operation environment, move the slider 30 to make the fixed bracket 3 reach an appropriate height, adjust the position of the slider 30 to optimize the stability of the scale 1 and the slider 30, and tighten the fastening bolt 31 to fix the slider 30 on slide 4;

[0037] S103: Adjust the support legs so that the support legs and the scale 1 together form a stable structure, tighten the locking mechanism to clamp the horizontal link 36 between the top plate 33 and the support plate 32, adjust the length of the support legs and lock them to make the level The bubble 2 is in the center, and the leveling work is carried out according to the requirements of the leveling specification.

Abstract

The invention discloses a leveling device and a measurement method thereof, relates to the technical field of leveling instruments and aims to solve the problems that during the measurement of an existing leveling rod, the leveling rod needs to be held manually, the work efficiency is low, and the data cannot be measured accurately because of shake of a worker who holds the leveling rod. The leveling device comprises a ruler which stands on a ruler pad, a leveling air bubble which is mounted on the side surface of the ruler, a slide way which is arranged along the longitudinal direction of the ruler and a fixing bracket which can slide relatively along the slide way, wherein the fixing bracket comprises a slider matched with the slide way, and bracket legs which are connected with the slider by bolts. The measurement method comprises the following steps: (1) vertically arranging the ruler on the ruler pad; (2) moving the slider to enable the fixing bracket to reach suitable height, and tightening and fixing the slider on the slide way; (3) regulating the bracket legs so that the bracket legs can form a stable structure with the ruler, tightening, regulating the length of the bracket legs and fixedly locking so that the leveling air bubble is in the middle and leveling can be realized.

Description

technical field [0001] The invention relates to the technical field of leveling instruments, in particular to a self-supporting leveling device and a measuring method for leveling review and guiding in building construction. Background technique [0002] Leveling is often used in construction engineering. It is a method of measuring the elevation of a ground point using a level and a leveling rod. Its basic principle is to measure the height difference between two points, so as to calculate the elevation of an unknown point based on the elevation of a known point. [0003] The leveling ruler usually used in leveling is indium tile ruler or indium steel ruler. This kind of leveling ruler has double-sided readings. During the measurement process, the staff need to manually support the ruler when reading the data on the ruler surface, and the workload of the staff is heavy. , it is extremely inconvenient to use and reduces work efficiency; more importantly, if the staff of the ...
