Ground lifting foldable horizontal drill gauge

Abstract

The invention discloses a foldable horizontal drill gauge which can be raised and lowered on the ground, which comprises a shell, an inner piece, a handle, and an adjustment rod and a dimension bar arranged on the upper surface of the shell. The lower surface of the shell is hinged with not less than three ring-shaped Evenly distributed telescopic rods, each telescopic rod is independently controlled by its own motor; the upper surface of the shell is also provided with a bubble level. The purpose of the present invention is to provide a foldable horizontal drill gauge that can be raised and lowered on the ground, which solves the problem that when using a drill gauge to measure in the prior art, it needs to be held manually and it is difficult to ensure its level, so as to improve the measurement accuracy of the drill gauge and facilitate induction. The purpose of placement.

Description

technical field [0001] The invention relates to the field of drill gauges, in particular to a foldable horizontal drill gauge that sits on the ground and can be raised and lowered. 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 drill g...

Problems solved by technology

[0004] The purpose of the present invention is to provide a foldable horizontal drill gauge that can be raised and lowered on the ground, which solves the problem that in the prior art, when the drill gauge is used for measurement, it needs to be held manually and it is difficult to ensure its level, so as to improve the measurement accuracy of the drill gauge and facilitate induction. purpose of placement

Aiming at the problem that the existing drill gauge needs to be held manually during measurement, it is difficult to ensure its level, which affects the measurement accuracy, the present invention proposes a foldable horizontal drill gauge that sits on the ground and lifts. 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 holding the drill gauge manually, and then pass it on the drill gauge. A bubble level is set on the surface, and the bubble level is used 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
