Embodiment Construction
[0031] Such as figure 1 As shown, the anti-collision method of this group of towers disclosed by the present invention installs positioning units respectively on the front end of each tower crane boom and on the tower crane trolley, each positioning unit includes two locators GPS and GSM, and the tower crane boom most The plane coordinate value of the front end is obtained after automatic correction by the independent positioning values of the two locators at this position, and the plane coordinate value of the tower crane trolley is obtained after automatic correction by the independent positioning values of the two locators at this position. The height coordinate value of the hook is obtained by the voltage and current method of releasing the cable. The height coordinate value of the tower crane can be automatically obtained by the corrected average value of the GPS locator of the positioning unit when the tower crane is stationary for a period of time, or through the ins...

The invention discloses a method for anti-collision of a group of towers, which includes the plane positioning and elevation positioning of the boom arm of the tower crane, the plane positioning of the walking trolley, and the elevation positioning of the trolley hook. After analyzing the plane position and elevation data of each tower crane through the cloud platform On the terminal display, set the warning range and danger range between adjacent tower cranes. When the boom of the adjacent tower crane enters the warning range, the terminal will alarm. When the warning range exceeds the danger range, the mechanical system will intervene urgently to make the tower crane Brake, forcing the operator to ensure safe operation, manually release the operation to keep the boom of the tower crane away from the warning range. GPS and GSM locators are set at the same time for plane positioning, and the independent positioning data of the two locators are corrected to obtain plane positioning data with higher accuracy; the resistance value of the release cable of the tower crane trolley is measured by the voltage and current method, and the resistance value passes through the length of the cable. After the data conversion module is processed, it is displayed on the terminal, and the accurate data of the height of the hook of the tower crane trolley is obtained.
Description
technical field [0001] The invention belongs to the application field of tower cranes on construction sites, and in particular relates to a method for preventing collision of group towers. Background technique [0002] Tower crane is the most important means of transportation that can solve both height and surface area heavy objects in the process of building construction. Due to the limitation of the coverage area of a single tower crane, it is very common to arrange two or more tower cranes at the same time in a construction site, forming a group tower operation situation. During the operation of group towers, when the coverage of two or more tower cranes overlaps, there is a risk of the booms of the tower cranes colliding with each other. At present, the main anti-collision measure for group tower operations is to adjust the height of adjacent tower cranes and stagger the heights of the booms of adjacent tower cranes. Although this avoids the direct collision of the b...
