Description
Technical Field
The utility model belongs to the technical field of hoisting machinery, more specifically say and relate to a light-weight adheres to festival convenient to equipment and lift by crane, especially be fit for assembling into the attached type body of light, welding few, the convenient concatenation with the unit festival of no attached type body of tower is joined in marriage.
Background
Tower cranes are used more and more widely in the industries of electricity, metallurgy, petrochemistry, construction and the like, and particularly, self-elevating tower cranes are more common. The tower body of the self-elevating tower crane works in a mode of standing vertical to the ground, and can be divided into an attached tower body (the tower body is connected with a nearby building) and a self-standing 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 tower body of the common self-elevating tower crane is formed by assembling tower crane unit sections with a traditional fixed structure. And the tower body structure of present attached self-elevating tower crane divides into two kinds: the first is that the tower body is formed by assembling and splicing whole-section reinforced attachment sections (QQJ) (see fig. 1), the whole-section reinforced attachment sections (QQJ) are formed by taking tower crane unit sections (DYJ) of a traditional fixed structure as a base body, welding reinforcing plates in the full length of the inner cavity side of each chord member and multiplying the number of vertical web members in the side surface of each prism, and the weight of the whole-section reinforced attachment sections (QQJ) is improved by more than 1 time compared with the weight of the tower crane unit sections (DYJ) of the traditional fixed structure (shown in fig. 3-5). Because the tower body structure of the attached self-elevating tower crane is formed by assembling and splicing the whole reinforced attachment sections (DYJ) with heavy weight and high rigidity, any point in the tower body of the structure can be selected as an attachment point and is matched with an external attachment connecting piece to be connected with a building, but the weight of the tower body of the structure is increased by times, the consumed materials are more, and the cost is high. The second tower body is formed by assembling a traditional fixed structure tower crane unit section (DYJ) and a whole section reinforcing attachment section (DYJ) together (see fig. 2), namely in the assembling process of the traditional fixed structure tower crane unit section (DYJ), a whole section reinforcing attachment section (DYJ) is generally added and assembled at an interval of 30 meters, and the whole section reinforcing attachment section (DYJ) is connected with a building by matching an external attachment connecting piece after an attachment point is selected. Compared with the tower body structure I, the tower body structure II of the attached self-elevating tower crane has the advantages that the weight of the tower body is greatly reduced, the material consumption and the cost are greatly reduced, any point of the whole reinforced attachment section (DYJ) can be selected as an attachment point, and the attachment connecting piece outside the attachment is matched with a building to be connected, but the weight of the whole reinforced attachment section (DYJ) is large, and the defects of lifting, mounting and positioning difficulty exist in the whole reinforced attachment section.
