Embodiment 1

[0017] A level for the construction of a power transmission line gate bar, such as figure 1 As shown, it includes a span measuring ruler 1 and two depth measuring rulers 2, the span measuring ruler 1 is used to measure the horizontal distance between two pole pits, and the two depth measuring rulers 2 are respectively installed at the two ends of the span measuring ruler 1, with For measuring the depth of two rod holes.

[0018] The span measuring ruler 1 includes a ruler sheath 12 and a retractable ruler core 11 sleeved in the ruler sheath. In the present embodiment, the chi core 11 and the chi cover 12 are all made of square steel pipes, the cross-sectional dimension of the inner wall of the chi core is 100mm × 150mm, the cross-sectional dimension of the outer wall is 106mm × 156mm, and the length of the chi core is 2.1m. The cross-sectional dimension of the inner wall of the cover 12 is 107mm×157mm, the cross-sectional dimension of the outer wall is 113mm×163mm, and the le...

Embodiment 2

[0029] A level for the construction of a power transmission line gate bar, such as figure 2 As shown, the difference with Embodiment 1 is that in this embodiment, the chi core 11 and the upper chi 21 are all telescopic rulers formed by connecting two scaled chi sections, and the length of the chi cover 12 is changed to 2.6m. .

[0030] The two sections of the chi core 11 are all made of square steel pipes, wherein the thinner section is sleeved into the thicker section to form a scalable structure. The length of the thinner section of the chi core is 1.6m, and the cross-sectional size of the inner wall It is 93mm×143mm, the cross-sectional dimension of the outer wall is 99mm×149mm; the length of the core of the thicker section is 2m, the cross-sectional dimension of the inner wall is 100mm×150mm, and the cross-sectional dimension of the outer wall is 106mm×156mm. Scales along the length direction are provided on the upper surfaces of the two cores 11 .

[0031] The two sect...

Abstract

The invention discloses a spirit level for power transmission line n-shaped rod construction. The spirit level for power transmission line n-shaped rod construction comprises a span measuring ruler used for measuring the horizontal distance between two rod pits of an n-shaped rod and two depth measuring rulers arranged on the end portions of the span measuring ruler respectively. The span measuring ruler comprises a ruler sleeve and a telescopic ruler core sleeved inside the ruler sleeve. The outer surface of the ruler core is provided with a scale. A level gauge is arranged on the outer surface of the ruler sleeve. The depth measuring ruler comprises a lower ruler and a telescopic upper ruler sleeved inside the lower ruler. The outer surface of the upper ruler is provided with a scale. The spirit level for power transmission line n-shaped rod construction is convenient to use and capable of directly measuring the horizontal distance between the two rod pits and the perpendicular distance between the bottom faces of the two rod pits, offering instructive parameters for n-shaped rod construction, omitting a large number of calculation processes and improving the construction efficiency to a large extent. In addition, the spirit level for power transmission line n-shaped rod construction further has the advantages of being small in error, easy to transport and store and the like.

Description

technical field [0001] The invention relates to a construction tool for electric facilities, in particular to a level used for adjusting the position and depth of two pole pits when embedding gate poles. Background technique [0002] The portal pole is a common pole type in power transmission lines, generally including two upright tower poles, and horizontal fork beams or cross arms are installed on the upper parts of the two tower poles. Due to its high rigidity and strength, the door rod is mostly used in occasions with relatively large loads. During the construction of the portal pole, according to the construction specifications, the two upright tower poles must be installed on the same horizontal base, and the depth of the two tower poles buried in the ground and the horizontal distance between the two tower poles are all within the design. Within the size range, to ensure that the stress of the two rods meets the design requirements. Therefore, two pole pits for bury...
