Description

Tower crane foundation protection device

Technical Field

The utility model relates to the technical field of tower crane installation, in particular to a tower crane foundation protection device.

Background

The tower crane is a crane which is the most commonly used in construction sites, is called a tower crane, is connected with standard sections, is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like, and is an essential device in construction sites.

The tower body of the tower crane has a rotation function and can be divided into a lower rotation tower crane and an upper rotation tower crane. The lower slewing tower crane has the advantages that slewing bearing, counterweight main mechanisms and the like are arranged at the lower end of the lower slewing tower crane: the tower type slewing bearing has the advantages of less bending moment, low gravity center, good stability and convenient installation and maintenance, and has the defects of higher requirement on the slewing bearing and limited installation height. Go up the tower crane of gyration tower with slewing bearing, balanced heavy, main mechanism all sets up in the upper end, its advantage is because the body of the tower does not revolve, can simplify body of the tower substructure, jacking join the convenience. The disadvantages are that: when the building surpassed the body of the tower height, because the influence of balance arm, the gyration of restriction tower crane, the focus was higher simultaneously, and the wind pressure increase, the ballast weight increases, makes the total weight of complete machine increase.

The stability of the tower crane is crucial, so the installation engineering of the tower crane has relatively high technical requirements. Firstly, whether the roadbed and the track are laid meet the requirements or not is checked, the ground anchor is buried, and the position of the ground anchor is determined according to the rotating and lifting direction of the vertical tower, the total height of the tower body and the like. The ground anchor is divided into a main ground anchor and an auxiliary ground anchor. The main anchor is the key for erecting the tower body, the whole load for rotatably lifting the tower body is borne by the main anchor, and the anchor is still needed to be used when the tower is disassembled, so the anchor must be carefully buried to achieve the required bearing capacity, and the corrosion prevention treatment is performed. The center of the ground anchor wheel is consistent with the center of the track gauge so as to ensure that the tower body rotates along the central plane of the track gauge all the time without generating eccentricity in the moving process of the tower body and ensure that the portal is stressed evenly. The auxiliary ground anchor is used as the anchoring point of the safety steel wire rope to prevent the tower body from falling in the opposite direction during the rotation process. In the tower crane installation project, a large amount of suspension operation is involved, so that the safety protection of workers is very important. The bearing points of the protective equipment for working aloft can be defined as fixing points for connecting life-saving ropes, safety ropes, speed-reducing equipment or other fall braking or rescuing systems. In the prior art, a conventional protection device relies on a safety rope for braking, so that the strength is relatively low, and the conventional protection device is related to the wearing state of constructors, so that the reliability needs to be improved.
