Problems solved by technology
At this stage, the calibration method of the inclinometer is to send the instrument back to the manufacturer for calibration. There is no easy and reliable method for the user to perform on-site calibration. The following problems exist: the calibration of the inclinometer not only takes a lot of time , and the price is expensive, and the long-distance transportation will increase the risk of damage to precision instruments

Embodiment Construction
[0044] The present invention will be further introduced below in conjunction with specific examples and accompanying drawings.
[0045] The calibration process of the present invention is as Figure 11 As shown, the inclinometer calibration is realized through the following steps.
[0046] 1. Making a simple calibration device for sliding inclinometers
[0047] A simple calibration device for sliding inclinometers such as figure 1 , 2As shown, it includes an upper positioning part 1, a lower positioning part 2, a side plate 3, a limit plate 4, a bottom plate 5, a lower plate 6, a spirit level 7, a rotating handle 8 and a locking handle 9. The two side plates 3 and the lower plate 6 are welded together, the angle 2θ between the two side plates is fixed and cannot be changed after welding, and a stable triangular bracket shape is formed after welding; the upper positioning part 1 and the lower positioning part 2 are fixed by countersunk screws Installed on the side plate 3, ...

The invention discloses a simple calibration method for a sliding inclinator. The calibration of the inclinator comprises the following steps of: manufacturing a simple calibration device for the sliding inclinator; calibrating an included angle of the simple calibration device for the sliding inclinator; leveling the simple calibration device for the sliding inclinator; performing calibration; and the like. A calibration process is simple and highly operable. A data processing method is more scientific and rational. A user can check or calibrate an apparatus on the spot. A requirement on the engineering measurement precision can be met, and the method is more practical. According to the calibration device, two side plates and a lower plate are welded into an integral three-legged support structure, and the side plates are made from 8# channel steel, so that the side plates are hardly deformed under a normal service condition, an included angle between the two side plates is ensured to be kept unchanged all the time, and the influence of a change in the included angle between the two side plates on a measurement result is radically eliminated.
Description
technical field [0001] The invention relates to a simple calibration method for a sliding inclinometer, belonging to the technical field of calibration of engineering measuring instruments. Background technique [0002] In recent years, with the large increase of domestic disaster prevention and mitigation and infrastructure construction projects, sliding inclinometers (hereinafter referred to as inclinometers) have been widely used as a high-precision engineering measuring instrument. At the same time, higher requirements are put forward for the performance and usage of the inclinometer, which are mainly reflected in: 1) The precision (accuracy) of the instrument engineering measurement is getting higher and higher; 2) The engineering measurement efficiency of the instrument has become One of the indicators that influences user purchases. Since the parameters of the inclinometer have creep properties over time, some parameters may deviate from the initial value, thereby af...
