Description
Technical Field
The invention belongs to the technical field of hoisting machinery, and particularly relates to a four-dimensional adjusting attachment device for connecting an attached tower body and a building.
Background
The tower crane is more and more widely used in the industries of electric power, metallurgy, petrifaction, building and the like, and particularly, the self-lifting tower crane is more common. The tower body of the self-elevating tower crane works in a mode of standing vertical to the ground, and the tower body can be divided into an attached tower body (the tower body is connected with a nearby building) and a self-supporting tower body or an unattached tower body (the tower body is not connected with the nearby building) according to different varieties and purposes. Because the attached tower body is provided with the lateral support, according to the design theory of the metal structure, the attached tower body is more reasonable in stress and better in rigidity, and can realize larger height and lifting capacity, and the whole machine is light in self weight and higher in safety. Because the self-supporting tower body does not need to be connected with a building or cannot be connected with the building (for example, a tower crane with low height does not need to be connected with the building; and a wind power tower crane is not allowed to be connected with a tower barrel), the maximum height of the tower body is influenced by rigidity and deformation, and the limit height is limited. Therefore, compared with the aspects of stress rationality, lifting capacity, lifting height, chassis occupied area, safety, economy and the like of the whole machine and the tower body, the attached tower crane has obvious advantages and has the advantages of reasonable stress, large lifting capacity, large lifting height and small chassis occupied area.
The attached tower body needs to be connected with a nearby building through an attaching device, namely, an attaching point is selected on an attaching node which is installed at a needed height and has strengthened rigidity, and then the attaching device is installed between the attaching point and the nearby building, so that a large rigidity body is formed. Due to the fact that the space between the tower body and a nearby building is narrow, namely the installation and disassembly space of the attachment device is also narrow, the reasonable attachment device is very important for installation, disassembly, stress and safety of equipment. The most common traditional attachment devices are a plurality of attachment rods with one end hinged on a building and the other end hinged on the nearest outer side surface in the tower body attachment section, and joint bearings for hinge connection are installed at the two ends of the attachment rods. Such conventional attachment devices have been found to suffer from the following disadvantages during use: the installation height and the installation distance cannot be adjusted, the requirements on the height and the strength of an attachment point are very strict, and the installation maneuverability is very poor; and the length of the attachment rod is fixed, and the attachment distance is changed slightly when changing the building site and just can not used repeatedly, and adaptability is poor, and the factor that the body of the tower sinks can lead to attachment means to interfere, the deformation is serious, and the security is poor in addition. Therefore, it is urgently needed to design an attachment device which can flexibly adapt to the height change of the attachment point, the length change of the attachment distance, frequent field transition and repeated use of a construction site and avoid installation interference and serious deformation caused by the sinking of a tower body.
