Abstract

The invention discloses a suspension cable strain measurement device. The suspension cable strain measurement device is characterized by comprising a measurement rod, wherein one end of the measurement rod is a fixed end, and the other end of the measurement rod is a measurement end. The fixed end of the measurement rod is connected with a fixed end hoop through a crosshead support, the movable end is connected with a measurement end hoop, and a movable end hoop can perform relative motion in the direction of the measurement rod. A measurement element is arranged on the measurement rod and comprises a body portion and a movable portion, wherein the body portion of the measurement element is connected with and fixed to the measurement rod through a measurement element body installing seat, and the movable portion of the measurement element is connected with and fixed to the measurement end hoop through a measurement element movable end installing seat. When the suspension cable strain measurement device is used, only the two hoops are needed to be installed on a suspension cable to be measured. The suspension cable strain measurement device is simple in structure, does not damage the suspension cable and is a reliable device capable of monitoring the strain of the suspension cable in real time.

Description

technical field [0001] The invention relates to a suspension cable strain measuring device, in particular to a device for monitoring the strain amount of the suspension cable before and after construction. Background technique [0002] The existing technology mainly uses strain gauges for measurement, and its main defect is that a connecting piece needs to be installed on the suspension cable, which will weaken the suspension cable and affect the structural safety. And the installation of the measuring device is time-consuming and laborious, and cannot be reused. Contents of the invention [0003] The object of the present invention is to provide a device capable of realizing real-time non-destructive monitoring of suspension cable strain. [0004] In order to solve the above problems, the present invention provides a suspension cable strain measuring device, which is characterized in that it includes a measuring rod, one end of the measuring rod is a fixed end, and the o...
