Description

Technical Field

[0001] The utility model relates to the technical field of tower crane balancing, in particular to an active balancing device for a tower crane. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also called "tower crane". It is connected in sections (referred to as "standard sections") to lift the raw materials for construction such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is an indispensable equipment on construction sites.

[0003] At present, the common construction tower cranes we see have a supporting tower in the middle. The nodes of the working arm and the balance arm are placed on the supporting tower and connected by a rotating shaft. Whether working or not, the position of the balance weight at the end of the balance arm is fixed. If it is balanced at a certain moment when the working arm is lifting the weight, it is unbalanced in other situations, and oblique stress is directly applied to the supporting tower. Sometimes, the working arm position when unloaded is compared with the working arm position when loaded, and the entire tower crane shakes several times, which is very dangerous. TV news often reports accidents of construction tower cranes hanging up.

[0004] With the development of science and technology, more and more new technologies and instruments are being used in the construction industry. Construction cranes are one of the important tools in construction. The height of construction cranes is generally high, which leads to poor stability of the crane itself and poor balance on the top. The current cranes are simply equipped with counterweights. At present, the counterweights are fixed. When lifting heavy objects, the balance is difficult to control because the construction crane will drop different weights, resulting in poor balance control and is dangerous during use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
