Among them, the support arm positioning and installation is an important link. The support arm positioning not only eliminates the prefabrication and installation errors of the special equipment support frame, but also provides a good reference platform for the subsequent plate installation and special equipment leveling; it is also necessary to find the best material taking position through support arm positioning to obtain the best separation effect; the accuracy of support arm positioning measurement and installation will also directly affect the subsequent operation life of the special equipment.

[0003] The original installation mode is to locate and install in sequence according to the given benchmark of civil engineering, and the subsequent installation benchmark is based on the previous installation benchmark. There are the following problems: 1) The dimensional error of the arm increases in the later stage of installation; 2) The subsequent installation dimensions of the arm are not related to the original benchmark dimensions, and there is no accurate basic dimension for accurate acceptance and correction; 3) The installation of the arm cannot be scaled and modularized, resulting in a long installation time, large deviation and high rework rate for the entire arm. Summary of the invention

[0004] In order to solve the problems existing in the above technologies, the patent of this invention proposes a method for positioning, measuring and installing the support arm. By relying on the reference size, using the tooling for precise positioning and measurement, and modularly measuring and installing the support arm in batches, large-scale rework caused by dimensional deviation during the installation of the support arm is avoided.

[0008] The first layer support arm positioning and adjustment tooling comprises a magnetic attractor, a support arm bracket a, an adjustment screw a, and a fastening screw a;

[0009] The support arm bracket a is L-shaped and connected to the magnetic attractor through a fastening screw a; the adjusting screw a passes through a through hole on the support arm bracket a;
