Abstract

The invention discloses a steel structure net frame lifting positioning system and method and relates to the technical field of steel structure net frame installation application. The steel structurenet frame positioning system and method are specific to the problems that an existing overall hydraulic synchronous lifting installation method of a steel structure net frame is excessively large in lifting overall deviation, extremely high potential safety hazards exist, in addition, the installation positioning operation is complex, and the construction efficiency is low. A lifting positioning device is arranged in each reserved hole site of a steel structure net frame, each lifting positioning device comprises a stirring rod foundation, a stirring rod vertically arranged on the top of the stirring rod foundation and connected with a bolt of the stirring rod foundation, a lifting assembly and a control system, wherein one end of the lifting assembly is connected with a horizontal cantilever beam on the top of the stirring rod, and the other end of the lifting assembly is connected with lifting points on the two sides of the corresponding reserved hole site of the steel structure netframe. Each control system comprises a lifting controller connected with an electric block of the corresponding lifting assembly, gravity sensors arranged close to the lifting points on the two sidesof the corresponding reserved hole site of the steel structure net frame and sub control boxes connected with the gravity sensors and the lifting controller, and the multiple sub control boxes are insignal connection with a master control box.

Description

technical field [0001] The invention relates to the technical field of steel structure grid installation and application, in particular to a steel structure grid lifting and positioning system and method. Background technique [0002] At present, the installation method of the steel structure network frame is to install the pulling rod on the hardened ground, and adjust the displacement and height deviation during the lifting process of the steel structure network frame through manual organization coordination and naked eye observation. Therefore, the installation quality of the steel structure network frame and The safety situation is not easy to control, for example: the lifting speed of each hoisting point of the steel structure grid cannot be controlled, and the overall lifting deviation of the steel structure grid is too large, resulting in a great safety hazard during the lifting process; when the steel structure grid is lifted to the design After the height, it needs ...
