Folding type lifting structure of one-arm three-dimension measuring scriber

Abstract

The invention discloses a folding type lifting structure of a one-arm three-dimension measuring scriber. The folding type lifting structure comprises a shell, an inner sheet, a handle, an adjusting rod arranged on the upper surface of the shell, and a size bar; the lower surface of the shell is hinged with at least three telescopic rods distributed circumferentially and uniformly, wherein the telescopic rods are independently controlled by their respective motors; and the upper surface of the shell is provided with a bubble level. With the folding type lifting structure of the one-arm three-dimension measuring scriber provided by the invention, the problem of low possibility of keeping a bit gauge horizontal caused by manual gripping in the prior art according to which the bit gauge is used to carry out measurement can be solved, and therefore, the measurement accuracy of the bit gauge can be improved, and storage and arrangement can be facilitated.

Description

technical field [0001] The invention relates to the field of drill gauges, in particular to a folding lifting structure of a single-arm three-dimensional measuring and marking instrument. Background technique [0002] Drill bit gauge is a common tool used in the oil and gas drilling industry to measure the gauge size of wear parts such as drill bits and centralizers. The downhole wear provides data support for drilling engineers to judge whether to replace the drilling tool assembly. During the measurement process using the drill gauge, insert it into the diameter gauge of the drill bit to be tested in the upright or suspended state and the centralizer, level the drill gauge with your hand, and turn the adjusting rod clockwise to make the inner piece of the drill gauge face inward Turn it out until it is close to the place to be measured. At this time, the size pointed by the pointer of the adjustment rod is the measured outer diameter. [0003] The user needs to keep the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a folding lifting structure of a single-arm three-dimensional measuring liner, which solves the problems in the prior art that when using a drill gauge to measure, it needs to be held by manpower and it is difficult to ensure its level, so as to improve the measurement accuracy of the drill gauge , and at the same time facilitate the purpose of inductive placement

Aiming at the problem that the existing drill bit gauge needs to be held manually during measurement, it is difficult to ensure its level, and the measurement accuracy is affected. A ring-shaped and evenly distributed telescopic rod, the telescopic rod is placed on the ground, and the three telescopic rods are used as supporting legs to ensure that the drill gauge is placed stably, avoiding the situation of unstable grip that may occur when using manpower to hold the drill gauge. Set a bubble level on the upper surface of the drill gauge, and use the bubble level to intuitively and accurately judge whether the drill gauge is in a horizontal state, so as to achieve the purpose of improving the measurement accuracy of the drill gauge
