Problems solved by technology

[0002] It is often necessary to use bridges to lay cables in power transmission equipment. The cable bridges in the prior art are generally hoisted on the vertical column suspension device, and the horizontal bridge support arm is welded on the vertical column as the bridge installation bracket. The vertical column, bridge support The arms are rigidly fixedly connected, and the installation size cannot be adjusted according to the measurement error during the installation process; the bridge support arm is fixed and installed by welding, and after a long time of use, the welding part of the support arm will also cause stress concentration due to vibration factors such as strong wind and air flow , and there is no vibration damping device in the bridge installation structure, which cannot resist the vibration caused by factors such as strong wind

Embodiment Construction

[0015] A bridge installation adjustment method, comprising the following steps:

[0016] a. On-site measurement of the distance from the beginning to the end of the cable tray, survey the distribution of horizontal and vertical lines on the installation site, and calculate the distribution points of vertical columns;

[0017] b. Pre-embed the structural parts according to the calculation results of the distribution points. When the structural parts are pre-embedded, the exposed parts need to be provided with a protective layer to prevent the civil engineering materials from covering the structural parts and affecting the installation of subsequent parts;

[0018] c. After the construction of the feudal structure of the construction project is completed, the vertical column with the opening slot shall be fixed and installed through the pre-embedded structural parts. The vertical column shall be kept horizontal and vertical, and the scale shall be used as the installation referen...

Abstract

The invention provides a bridge stand installation and adjustment method. The installation position of each bridge stand support arm on the corresponding vertical column is adjusted through the adjustment mechanism of each bridge stand support arm so that the bridge stand installation position is enabled to meet the requirements of field installation size, the field installation size can be adjusted in the installation process to compensate measurement error and thus the vibration resistance is great and installation operation is convenient; and the adjustable bridge stand support arms have nowelded fixed connection point so that stress concentration does not occur, and vibration caused by strong wind and other factors can be resisted.

Description

technical field [0001] The invention relates to a bridge installation and adjustment method. Background technique [0002] It is often necessary to use bridges to lay cables in power transmission equipment. The cable bridges in the prior art are generally hoisted on the vertical column suspension device, and the horizontal bridge support arm is welded on the vertical column as the bridge installation bracket. The vertical column, bridge support The arms are rigidly fixedly connected, and the installation size cannot be adjusted according to the measurement error during the installation process; the bridge support arm is fixed and installed by welding, and after a long time of use, the welding part of the support arm will also cause stress concentration due to vibration factors such as strong wind and air flow , and there is no vibration damping device in the installation structure of the bridge frame, which cannot resist the vibration caused by factors such as strong winds. ...
