Abstract

The invention relates to a multi-point intelligent lifting and positioning cable stress detection instrument, which comprises a frame body sheathed on a stay cable of a cable-stayed bridge; and at least two sensor pushing mechanisms which comprise a brush DC motor, a No.1 telescopic push rod, a No. 2 telescopic push rod, a rotatable type connecting end, a vertical adjustment rod and a sensor fixing support. The brushed DC motor drives the screw rod to rotate and achieves the telescopic function through the engaged transmission between the internal thread of the No. 1 telescopic push rod and the screw rod; the No. 1 telescopic push rod drives the No.2 telescopic push rod to rotate so as to achieve the telescopic function; and the sensor fixing support is fixedly mounted at the end of the vertical adjustment rod, and the sensor fixing support is provided with a sensor chip. The driving mechanism comprises a driving motor and a driving wheel, wherein the driving motor drives the driving wheel to roll upwards and downwards along the cable-strayed bridge. According to the invention, the frame body is provided with at least two sensor pushing mechanisms, which cooperate with the sensor chip mounted on the frame body to realize simultaneous multi-point measurement and to make the cable stress detection data more accurate.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a multi-point intelligent lifting and positioning cable force detector for cable force detection of cable stays. Background technique [0002] The cable-stayed bridge is an important type of bridge. The cable-stayed cable is one of its main stress components. Its working state is the decisive factor for the safe operation of the cable-stayed bridge. Therefore, it is necessary to The internal force of the cable is measured to ensure that the stay cable is in a normal stress state. [0003] At present, in engineering applications, there have been devices that can automatically climb and detect the cable force. After these devices climb to a certain position, the sensors on the device can measure and transmit the results, but are affected by the wind force on the bridge and the cable itself. Due to the influence of nature, the device is often in an unstable state at a high p...
