Description

Technical Field

[0001] The utility model relates to the technical field of mine distance measuring equipment, in particular to a high-precision positioning and measuring device for underground mines. Background Art

[0002] A handheld rangefinder is a compact instrument used for distance measurement, utilizing principles such as electromagnetism, optics, and acoustics. Its principle: A handheld rangefinder emits a thin laser beam toward a target. A photoelectric element receives the reflected laser beam, and a timer measures the time between emission and reception to calculate the distance from the observer to the target. As a portable measurement tool, handheld rangefinders are widely used in underground mines. They can be used to measure parameters such as tunnel length and width, providing data support for mine planning and design.

[0003] An existing published patent (publication number CN214703974U) discloses a handheld rangefinder, comprising a rangefinder body, on which a laser transmitter, an operating panel, and a display screen are fixedly mounted. A gripping structure is slidably connected to both sides of the rangefinder body, and a support structure is mounted on the gripping structure. The utility model provides adjustable, slidable gripping structures on both sides of the rangefinder body, each with a finger groove. This not only facilitates the user's handling of the rangefinder body, but also allows the adjustable, slidable gripping structure to be adjusted to become a support structure, allowing the rangefinder body to be fixed at a certain point and then moved to an object at the measured point. The user can operate the device by themselves without the need for cooperation from others, thus reducing labor costs and making fixed-point measurement more convenient.

[0004] However, there are some problems in the use of existing handheld rangefinders for high-precision positioning and measurement in underground mines. The handheld rangefinders for high-precision positioning and measurement in underground mines currently on the market have low accuracy in verifying other positioning and measurement technologies when in use. There is a lack of a measure that can be assembled to increase the accuracy of ranging and positioning, which reduces its overall usability. Utility Model Content
