Caliper for measuring gradient of power transmission line tower

Abstract

The invention discloses a caliper for measuring the gradient of a power transmission line tower, and the caliper comprises a bearing assembly which comprises a bearing disc, wherein the surface of the bearing disc is symmetrically and fixedly connected with L-shaped supporting rods in an inserted manner, the end parts of the L-shaped supporting rods are fixedly connected with a positioning plate, and the positioning plate is detachably fixed on the power transmission line tower through a fixing mechanism; a caliper assembly which comprises an installation opening formed in the bearing disc, wherein a fixing shaft is fixedly inserted into the installation opening, the middle of the fixing shaft is movably sleeved with a caliper structure, and the caliper structure is movably connected with the fixing shaft through a bearing; the fixing shaft is movably sleeved with swing arms located on the two sides of the caliper structure, a telescopic rod is horizontally and fixedly connected to the end of the swing arm on one side in an inserted mode, and the end of the telescopic rod perpendicularly faces the plane where the positioning plate is located and is detachably and fixedly connected with a steel frame on the power transmission line tower. The caliper is simple and rapid in installation, convenient in measurement and high in measurement precision.

Description

technical field [0001] The invention relates to the technical field of voltage transmission line operation and maintenance, in particular to a caliper for measuring the inclination of a transmission line tower. Background technique [0002] In the operation and maintenance of high-voltage transmission lines, it is often encountered that the top of the tower deviates from the normal position due to the unstable foundation, resulting in a tilting problem. If the tilting phenomenon of the tower is not dealt with in time, the force on the cross-arm part will change, the wire and the center of gravity of the tower will shift, and the serious consequences will lead to the accident of breaking the pole and falling the tower. Therefore, in the daily inspection work, it is necessary to measure the inclination of the tower regularly. [0003] When measuring, it is necessary to place the measuring tool on the road pole tower. The position has a certain height, and the inclination of t...

Problems solved by technology

[0003] When measuring, it is necessary to place the measuring tool on the road pole tower. The position has a certain height, and the inclination of the road pole tower is generally small. value, thereby reducing the measurement accuracy; and the measurement tool placed at a certain height may be affected by the air flow during the measurement process, which interferes with the normal measurement process of the measurement tool and further reduces the measurement accuracy. Therefore, we propose a power transmission Calipers for line tower inclination measurement

[0004] Publication Nos. CN213932484U and CN212539156U disclose the relevant technical solutions of the tower inclination measurement auxiliary caliper, but its installation and use are inconvenient and the measurement accuracy is limited
