Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, and in particular relates to a leveling measuring ruler support. Background Art

[0002] Leveling, also known as "geometric leveling", is a method of measuring the height difference between two points on the ground using a level and a level rod. A level is placed between two points on the ground, and the level rod erected at the two points is observed. The height difference between the two points is calculated based on the readings on the rod. Usually, starting from the leveling origin or any known elevation point, the elevation of each point is measured station by station along the selected leveling route.

[0003] There are many factors that affect the measurement error during field measurement, among which the tilt of the level rod affects the reading on the rod. In order to reduce the negative impact caused by the tilt of the level rod, observers can use auxiliary means of supporting the rod, including self-made support rods, purchasing finished rod supports, etc. At present, the products of level measurement rod supports on the market are relatively simple, and their support rods are mostly telescopic structures, which need to be manually adjusted and fixed, and the level rod needs to be manually clamped, which greatly affects the efficiency of level measurement and is not conducive to the protection of the turning point during the level measurement process. Therefore, it is urgent to optimize and improve the structure of the rod support, and propose to use an automatically clamped slot and a movable telescopic damping rod to replace the original mechanically adjusted telescopic support rod, so as to improve the efficiency of the use of the rod support and the efficiency of the rod support work, reduce the risk of damaging the stability of the turning point due to frequent adjustment of the rod support, and thus ensure the accuracy and stability of the level measurement data.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 3As shown, a level measuring ruler support includes a clamping ruler frame 1 and two telescopic damping rods 2, the two telescopic damping rods are connected to one side of the clamping ruler frame, and a clamping groove 3 for clamping the level measuring ruler is provided on the side of the clamping ruler frame away from the telescopic damping rod, and an elastic pad 7 is coated on the inner wall of the clamping groove, and the elastic pad can protect the level measuring ruler to prevent it from being worn during the clamping process. Specifically, sponge can be used. The clamping ruler frame includes a first clamping member 101 and a second clamping member 102, and the first clamping member and the second clamping member are connected by at least one spring 4. In this embodiment, the number of springs is two, which are a first spring 401 and a second spring 402 arranged in parallel with each other, to ensure that the first clamping member The connection stability between the first clamping member and the second clamping member, the two telescopic damping rods are both installed on the first clamping member, and the second clamping member is located on the side of the first clamping member away from the two telescopic damping rods.
