Problems solved by technology
[0002] The cable tray needs to be suspended and hoisted on the top of the factory building, equipment, and buildings through the column. The traditional cable tray is generally fixed and welded on the vertical column. The horizontal bridge bracket is used as the bridge installation bracket. The vertical column and the bridge bracket are evenly fixed and connected. , while the bridge products are generally rough in the pre-measurement, the installation error is large, the installation size cannot be adjusted according to the measurement error during the installation process, and the installation can only be forced to deform through rough installation methods such as knocking, which affects the use effect of the bridge, and the bridge is easy to deform ; After a long time of use, the welding part will also cause stress concentration due to vibration factors such as strong wind and air flow, and there is no vibration damping device

Embodiment Construction
[0021] As shown in the figure, a method for adjusting a dial-type bridge includes the following steps:
[0022] 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;
[0023] b. Pre-embed structural parts according to the calculation results of distribution points;
[0024] c. After the construction of the feudal structure of the construction project is completed, the adjustable column is fixed and installed through the embedded structural parts;
[0025] d. Install the dial-type adjustable bridge support arm in the opening slot of the adjustable column;
[0026] e. Use a spirit level to verify the overall levelness of the adjustable bridge support arm. If the adjustable bridge support arm is lower than the overall horizontal line, press its far end so that the inner limit pin pulls out the positioning ...

The invention provides a lifting type bridge-frame adjustment method. Each support arm is adjusted by a corresponding lifting type adjustable support arm to an installation position on a corresponding adjustable stand column, and the overall level degree of all the lifting type adjustable bridge-frame support arms are verified through a level gauge, so that the bridge-frame installation position meets the field installation dimension requirement; in the installation process, the field installation dimension can be adjusted so as to compensate measurement errors, the vibration resistance is good, installation and operation are convenient to conduct, the adjustable bridge-frame support arms have no weld fixation connection point, stress concentration is not caused, and vibration caused by high wind and other factors can be resisted.
