Balancing weight positioning mechanism of tower crane

Abstract

The invention discloses a balancing weight positioning mechanism of a tower crane, belongs to the technical field of tower cranes, and adopts the following technical scheme: the balancing weight positioning mechanism comprises a rotating arm and a plurality of balancing weights mounted on the rotating arm through a plurality of fixed pins; the plurality of balancing weights are attached and aligned with one another; a handle is fixedly mounted at the top of each balancing weight; a movable cover is slidably arranged at the upper end of the rotating arm; the movable cover is inversely buckled on the rotating arm in a U-shaped manner; the movable cover can completely cover the plurality of balancing weights in the sliding process; an insertion plate is arranged on the inner side of the movable cover; the insertion plate is in an L shape and can horizontally penetrate through the plurality of handles at the same time; and a first electric winding mechanism and a second electric winding mechanism are respectively mounted at the positions, located on the two sides of the movable cover, of the upper end of the rotating arm, and are connected with the movable cover through a first steel cable and a second steel cable wound thereon. According to the balancing weight positioning mechanism of the tower crane, the balancing weights can be more stably mounted on the rotating arm.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a counterweight positioning mechanism of a tower crane. Background technique [0002] Tower cranes generally refer to tower cranes, which are the most commonly used lifting equipment on construction sites. They are used to hoist construction materials such as steel bars, wood corrugated, concrete, and steel pipes. They are an indispensable equipment on construction sites. . There are several counterweights installed on the rotating arm of the tower crane. Traditional tower cranes usually only use fixed pins to install the counterweight and the rotating arm together. However, when encountering severe weather or geological disasters, This installation structure will cause a greater risk of the counterweight falling. Therefore, it is necessary to design a counterweight positioning mechanism to improve the stability of the installation structure between the counterweight and th...
