Device and system for detecting power transmission tower node quality based on laser

Abstract

The invention discloses a device and system for detecting the node quality of a power transmission tower based on laser, and the device comprises a workbench and a to-be-detected part, wherein the workbench is provided with a working surface, the to-be-detected part is disposed on the upper surface of the working surface, a portal frame is erected above the workbench, and the portal frame is provided with a laser detector. The working surface is connected with a driving device for driving the to-be-detected part to move horizontally, the detection area of the laser detector is perpendicular tothe moving direction of the to-be-detected part on the upper surface of the working surface, when the to-be-detected part moves to the position below the laser detector, the laser detector works, andthe scanning area of the laser detector covers the to-be-detected part; the light source transmitting tube transmits laser to the to-be-detected part through the light source transmitting port, the light source receiving port collects the light source reflected by the to-be-detected part, the receiving lens group transmits the reflected light source to the imaging array, and the information processing device calculates and obtains the three-dimensional measurement value of the to-be-detected part, so that the precision of the screened to-be-detected part is improved. And later maintenance ofthe power transmission tower is reduced.

Description

technical field [0001] The invention relates to the technical field of electric tower detection, in particular to a laser-based device and system for detecting the quality of transmission tower nodes. Background technique [0002] In the transmission line system, as the core component of the transmission tower, the bearing capacity of the tower determines the overall performance of the transmission system. In the current research on the transmission tower line system, the angle steel transmission tower or steel pipe transmission tower is generally simplified into a simple space beam structure. The tower body components of the transmission tower include main inclined materials, auxiliary materials, gusset plates and bolts, etc. The node connection structure, accurate size of tower body components, reasonable installation and high adaptability are the key factors affecting the normal operation of the tower.

AI Technical Summary

Problems solved by technology

[0003] During the normal service of the transmission tower, because the transmission tower has been subjected to strong excitations such as wind, rain, ice and lightning for a long time, unreasonable bolts installed on the node plate of the transmission tower are more likely to loosen, fall off or even be damaged. The stress of the main material, inclined material and gusset plate in the bolted connection area changes significantly, and the bearing capacity of the transmission tower node decreases significantly, thus affecting the normal working life of the transmission tower, and the inaccurate size of some tower body components may easily lead to Reduction of the wind force and earthquake magnitude of the transmission tower
