A pointer homing type automatic adjustment and measurement tripod

Abstract

The invention discloses a pointer homing type automatic adjustment and measurement tripod, belonging to the technical field of measurement, which can realize rapid automatic adjustment of the levelness of the tripod, and jointly guide the lifting adjustment of self-elevating outriggers through a triangular pressure contact and a central pressure contact Specifically, the technician first controls one of the self-lifting outriggers to rise to a suitable height in advance, and then automatically adjusts the other self-elevating outrigger to the same height, and the self-moving indicator ball driven by the self-rotation limit shift pointer stays to press the last self-lifting The triangle pressure contact corresponding to the outrigger shall prevail, and then the last self-lifting outrigger is automatically adjusted until the self-moving indicator ball moves precisely along the self-rotation limit movement pointer to the center pressure contact, so as to realize the roughness of the horizontal plane and greatly shorten the adjustment time. Improve the measurement efficiency, and at the same time, within the allowable range of measurement error, by setting a weak angle control loop to meet the offset of the self-moving indicator ball within a certain range, the measurement accuracy can be effectively improved within the tolerance range.

Description

technical field [0001] The invention relates to the technical field of measurement, and more particularly to a pointer return type automatic adjustment measurement tripod. Background technique [0002] A tripod is a support frame used to stabilize the camera to achieve certain photographic effects. The positioning of the tripod is very important. Tripods can be classified into wood, high-strength plastic materials, aluminum alloy materials, steel materials, volcanic stone, carbon fiber, etc. [0003] Generally, people tend to ignore the importance of tripods when taking pictures with digital cameras. In fact, photo shooting is often inseparable from the help of tripods, such as star trail shooting, flowing water shooting, night scene shooting, macro shooting and so on. The function of a tripod can not be ignored for both amateur and professional users. Its main function is to stabilize the camera to achieve a certain photographic effect. The most common way is to use a tri...

Problems solved by technology

[0004] The tripod is not only used to stabilize the camera, but also widely used in the field of measurement, and the stability and accuracy requirements are more stringent than that of the camera. At present, the tripod needs to be installed and roughed before the measurement. Most of the tripods on the market are Manually adjust the rough level, laying a solid foundation for the installation and fine leveling of the measuring instrument, and one of the most important tasks in the measurement process. However, manual adjustment is laborious, and it is necessary to adjust the three legs back and forth while observing the level bubbles. For For mature technicians with certain measurement experience, the adjustment time generally takes about 30s, while for newcomers with less experience, the adjustment time generally exceeds 2min, which generally consumes more time and is less efficient, especially in long-distance In the measurement, it is necessary to continuously adjust the tripod, and even the leveling measurement or traverse measurement of several kilometers a day needs to be adjusted hundreds of times. At this time, the time consumption of the adjustment will greatly delay the measurement process and seriously slow down the measurement efficiency
