A hand-controlled sliding inclinometer with rollers

Abstract

The invention relates to a sliding inclinometer with manually controlled rollers. By adding a high-carbon steel wire strand to the original wire, when the steel wire strand is pulled up, the steel wire strand can move upward in the spiral net; the steel wire The twisted wire is connected to the roller clip through the fixed pulley. When pulling up the steel wire strand, the steel wire strand realizes angle transformation through a fixed pulley at the roller place, so that the steel wire strand can be easily pulled up to make the roller smoothly adducted. When the device is stuck, it can be smoothly pulled up and taken out by retracting the rollers. It effectively avoids damage to the device, saves construction costs, ensures the smooth progress of monitoring work, and ensures the accuracy of monitoring data. This device is suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to an inclinometer, in particular to a sliding inclinometer with rollers that can be manually controlled. Background technique [0002] Sliding inclinometers are mainly used to measure deep foundation pits, slopes, foundations, and horizontal displacements. By drilling, the measuring groove pipe is buried in the ground. When the foundation pit, slope, and foundation deform, the measuring groove pipe deforms accordingly, and the pulley on the measuring head goes down the groove to test point by point, so that it can be accurately measured. Output horizontal displacement ΔX, Y. According to the value of ΔX, Y, make a forecast and guide the construction. [0003] This type of instrument uses the latest imported inclination sensor as the sensitive element. It is a force-balanced servo system. When the sensor probe has an inclination angle relative to the direction of the earth's center of gravity, due to the action of gravity, the s...

AI Technical Summary

Problems solved by technology

[0004] Existing inclinometers are expensive. Once the inclinometer tube breaks and the rollers are stuck outside the inclinometer tube wall, the measuring head cannot be pulled up. It is too troublesome and expensive to dig out the surrounding obstacles to take out the measuring head. It is high and has a harmful impact on the project. At present, there is no way to easily pull up and take out the side head after such an engineering situation occurs

When the roller of the existing inclinometer is stuck, the roller cannot be retracted, so it cannot be pulled out upwards in the inclinometer tube
