Problems solved by technology

[0003] With the rapid development of urbanization in China, tower cranes are the most common lifting equipment on construction sites. In construction, they are mainly used to hoist building materials for construction and are one of the essential equipment on construction sites. , in traditional tower cranes, the lifting mechanism is generally installed at the end of the balance arm, and during the rotation of the balance arm, the cables used to supply power to the lifting mechanism are prone to knotting, if not handled in time, it is easy to Accidents, therefore, the limited range of rotation of the balance arm

Abstract

An anti-twist structure of a building tower-crane device comprises a tower body, a rotating stand and a tumbler, wherein the rotating stand is rotatably installed at the upper end of the tower body, and the tumbler is fixedly installed at the right end of the rotating stand. A groove is formed in the upper end of the tower body, a threading cam is fixedly installed in the middle of the lower end of the rotating stand and used for allowing a plurality of electrified cables to pass through separately, the threading cam is rotatably connected with an elastic feeding piece fixedly installed in the tower body and located at the lower end of the groove through two sliding bars which are fixedly connected, and cross rotary discs are slidably installed on the two sliding bars; and after the multiple electrified cables penetrate through the cross rotary discs from the rotating stand, the electrified cables can cross with one another and are connected with an electrified column on the elastic feeding piece, and the multiple electrified cables further penetrate into the tumbler from the inner portion of the rotating stand and are connected with electric equipment.
