Self-adaptive displacement wire measuring and reading system

Abstract

The invention discloses a self-adaptive displacement wire measuring and reading system. The system comprises an automatic centering mechanism; a fixing frame of the automatic centering mechanism is arranged on the ground; the automatic centering mechanism comprises a frame provided with rails; a sliding frame capable of sliding left and right is connected between the rails in a sliding mode; a movable groove is formed in the sliding frame; a sliding plate assembly capable of sliding front and back is connected to the movable groove in a sliding mode; a winding pulley is rotatably fixed on the sliding plate assembly; an angular displacement sensor and the winding pulley are coaxially mounted; the ground part of an upper displacement wire assembly is wound on the winding pulley; a balancing weight is fixed at the end part of the upper displacement wire assembly; the underground part of the upper displacement wire assembly is fixed above a load box to be measured; and a lower displacement wire assembly is fixed at the lower part of the load box to be measured. Through the automatic centering mechanism, under the gravity effect of the counterweight block, a displacement wire is automatically and vertically straightened; the angular displacement sensor is adopted, direct measurement and reading of the transmission displacement of the displacement wire are achieved; and therefore the testing precision of the displacement wire is improved.

Description

technical field [0001] The invention relates to the field of displacement measurement and reading, in particular to an adaptive displacement wire measurement and reading system. Background technique [0002] At present, common displacement detection devices mainly include displacement rod type displacement detection device, displacement wire type displacement detection device and other types. The existing displacement rod type displacement detection device is widely used. The rigid rod is fixed on the pile body to measure the displacement, the rigid rod is extended to the ground, and a dial indicator or displacement sensor is installed on the top of the rigid rod to detect the displacement. The rigid rod Pipe protection is required on the outside. In the installation process of this method, each piece of rigid rod is 3-6 meters, which needs to be connected and used by multiple pieces, and cannot be reused, so there are problems of installation trouble and waste of resources...

AI Technical Summary

Problems solved by technology

[0003] From a technical point of view, the flexible steel wire is more adaptable to the influence of the slope of the pile body, and its transmission accuracy to the displacement should be better; however, in a large number of application examples, the test accuracy of the displacement wire is far lower than the theoretical accuracy.

Therefore, it can be seen that there are many influencing factors in the prior art, which lead to deviations in the measurement

[0004] When the displacement detection device is used for detection, most of the traditional devices have a fixed structure, resulting in the inability to adjust the position of the upper end, resulting in a deviation between the displacement wire and the load box during displacement measurement, and the displacement wire cannot be set by plumb. , thus affecting the effect of the measure
