Description

Anti-falling mechanism for tower crane hanging box for house building

Technical Field

The utility model relates to a construction machinery technical field, in particular to tower crane hanging box anti-falling mechanism for housing construction.

Background

The tower crane is the most common hoisting equipment on the construction site, also called tower crane, and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction by the extension (height) of one section and one section (called standard section for short). The tower crane is indispensable equipment on a construction site, and the tower crane tip has the function of bearing upper loads transmitted by a boom pull rope and a balance arm pull rope and directly transmits the upper loads to a tower body structure through a rotary tower, a rotary table, a bearing seat and other structural components. The self-elevating tower top is provided with a truncated cone column type, a forward-inclined or backward-inclined truncated cone column type, a herringbone frame type and an inclined support frame type. The upper slewing tower crane is required to be provided with a balance weight, and the function of the upper slewing tower crane is to support the balance weight so as to form a balance moment which is required by design and has the action direction opposite to the lifting moment direction. In addition to the counterweight, a hoisting mechanism is often provided at the tail. The hoisting mechanism and the balance weight are arranged at the tail end of the balance arm together, so that partial balance weight function can be achieved, and the distance between the rope reel and the tower tip guide wheel is increased, so that the steel wire rope can be conveniently wound and rope disorder is avoided.

Current tower crane generally adopts a simple couple when the handling thing, and the hanging box rope that will be equipped with building material through the couple catches up and carries out the handling, behind building material handling to assigned position, hanging box weight becomes light, meets strong wind weather, and the hanging box can produce and rock, and the rope that leads to the hanging box easily drops from the couple, leads to the hanging box wholly to fall, has the potential safety hazard to the ground staff.
