Embodiment Construction
[0032] 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 preventing collision between group towers, comprising the plane locating and elevation locating of tower crane arms, the plane locating of a walking trolley and the elevation locating of a trolley hook. The plane position and elevation data of each tower crane are analyzed through a cloud platform, and are then displayed on a terminal. The warning range and danger range between adjacent tower cranes are set. When the arm of an adjacent tower crane enters the warning range, the terminal gives an alarm. When the arm of an adjacent tower crane is beyond the warning range and enters the danger range, a mechanical system is put in use to make the tower crane brake under emergency, and an operator is forced to manually remove the operation to make the arm ofthe tower crane away from the warning range under the condition of safe work. GPS and GSM locators are set for plane locating. More precise plane locating data can be obtained after the independent locating data of the two locators is modified. The resistance value of the release cable of the tower crane trolley is measured through a voltage and current method, the resistance value is processed bya cable length data conversion module and displayed on the terminal, and then, precise elevation data of the tower crane trolley hook 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...
