Foundation bolt positioning device suitable for power transmission tower

Abstract

The invention discloses a foundation bolt positioning device suitable for a power transmission tower. The foundation bolt positioning device comprises a positioning plate, a sliding rail, a level gauge, a foundation bolt clamp, a supporting frame and a laser centering device; a plurality of pairs of sliding rails are symmetrically arranged on the positioning plate, the level gauge is arranged on the positioning plate, each sliding rail is connected with the foundation bolt clamp in a sliding mode, a telescopic supporting frame is arranged at the bottom of the positioning plate, and the laser centering device is arranged at the positions, at the center positions of the plurality of pairs of sliding rails, of the positioning plate. According to the foundation bolt positioning device, the foundation bolt can be rapidly and accurately positioned in electric power engineering construction and can be repeatedly used, the problems that foundation bolt positioning is complex, foundation bolt positioning errors are reduced and the like in current construction are solved, and the foundation bolt positioning device has the advantages of being low in cost, easy to install and the like and has good economic benefits and application prospects.

Description

technical field [0001] The invention relates to the technical field of power transmission building facilities, in particular to an anchor bolt positioning device suitable for power transmission towers. Background technique [0002] In the construction of transmission line engineering, anchor bolts are usually pre-buried in the foundation, and the ends of the anchor bolts are exposed to the ground to connect the bottom of the tower. [0003] The installed anchor bolts need to be calibrated. The length and verticality of the anchor bolts exposed to the ground meet the design requirements. The correction process is prone to deviations and consumes energy, and the concrete pouring in the foundation construction is likely to cause the anchor bolts to tilt. [0004] For the correction of anchor bolts, the general method is to use manual observation with the naked eye, or use a ruler with a scale to measure the alignment. Often these methods are not accurate for the alignment or me...

AI Technical Summary

Problems solved by technology

[0003] The installed anchor bolts need to be calibrated. The exposed length and verticality of the anchor bolts meet the design requirements. The correction process is prone to deviations and consumes energy. In addition, the pouring of concrete during foundation construction tends to tilt the anchor bolts.

[0004] For the correction of anchor bolts, the general method is to use manual observation with the naked eye, or use a ruler with a scale to measure the alignment. Often these methods are not accurate for the alignment or measurement of the anchor bolts, and there will be small errors. , the height is different or inclined, which will affect the subsequent construction of utility poles or pipe towers.

[0005] Usually, the number of anchor bolts for iron towers with a voltage level of 220kV and below is usually 4, which are symmetrically arranged. The arrangement of anchor bolts of different specifications is generally fixed; anchor bolts play an important role in connecting the iron tower and the foundation in the power transmission and distribution lines, connecting the upper and lower Its role is related to the safe operation of the entire line. Once the anchor bolts are leaked, fatal accidents such as tower collapses will most likely occur.
