Problems solved by technology
[0002] At present, the balance of most tower cranes is completed by counterweights. The counterweights are adjusted according to the hoisting weight to complete the entire balance system, but the overall balance is passive and the stability is poor. There will be a certain range when hoisting heavy equipment. The swing, and the ability to resist strong winds is also weak, and the overall balance performance is not good

Embodiment Construction
[0010] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0011] Such as figure 1 As shown, the tower crane active stability maintenance system of the present invention is composed of a tackle assembly 1, a pulley groove 2 of the tower crane arm, a steel cable 3 and a balance ellipsoid 4, the lower end of the steel cable 3 is connected to the balance ellipsoid 4, and the upper end is connected to the tackle assembly 1 .
[0012] Such as figure 2 Shown, described tackle assembly 1 is made of longitudinal pulley 5, pulley groove 6, transverse pulley 7, electronic level 8, microcomputer chip 9, transverse tackle 10, longitudinal tackle 11, universal joint 12, pulley shaft 13. The left and right sides of the longitudinal block 11 are respectively equipped with a longitudinal pulley 5 through the pulley shaft 13, and two pulley grooves 2 are arranged on the tower boom, and the longitud...

The invention discloses an active stability maintaining system for a tower crane. The active stability maintaining system for the tower crane is mainly composed of a longitudinal tackle, a transverse tackle, a steel cable and a balanced ellipsoid, wherein longitudinal pulleys at two sides of the longitudinal tackle are arranged in pulley grooves of a tower crane boom, transverse pulleys at two sides of the transverse tackle are arranged in pulley grooves at the top part of the longitudinal tackle, and the pulley groove at the top part of the longitudinal tackle is perpendicular to the pulley groove of the tower crane boom mutually; and a microcomputer chip for controlling the actions of the longitudinal tackle and the transverse tackle and an electronic level meter for detecting the inclining angle of the tower crane are arranged on the transverse tackle, the top part of the longitudinal tackle is connected with the steel cable by an universal joint, and the other end of the steel cable is connected with the balanced ellipsoid. According to the active stability maintaining system for the tower crane, an electronic system in the tackle is used for judging the inclination degree of a tower crane body, the tackle is controlled to drive the balanced ellipsoid to move to actively change the gravity center of the tower crane body to realize balance of the tower crane, the stability of the tower crane is effectively improved, shaking caused by hoisting and unloading can be reduced, the anti-wind capacity of the tower crane can be improved, and the accidents such as overturning of the tower crane and the like can be prevented actively.
Description
technical field [0001] The invention relates to the technical field of tower crane accessories, in particular to a tower crane active stability maintenance system. Background technique [0002] At present, the balance of most tower cranes is completed by counterweights. The counterweights are adjusted according to the hoisting weight to complete the entire balance system, but the overall balance is passive and the stability is poor. There will be a certain range when hoisting heavy equipment. The swing, and the ability to resist strong winds is also weak, and the overall balance performance is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an active stability maintenance system for a tower crane to improve the safety, stability and wind resistance of the tower crane. [0004] The active stability maintenance system of the tower crane of the present invention is mainly composed of a longitudinal block,...
