Problems solved by technology

However, because of the fixed position of the vertical side of the hanger of this kind of structure, the centered vertical side has obstacles to the operation of the embedded bolt connection, causing inconvenience in the operation of hand tools and the situation that electric tools cannot be used. Therefore, the hanger of the prior art is There are obvious defects in the application in the project, which needs further improvement

Embodiment Construction

[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0017] The hinged spreader shown in the accompanying drawing is composed of a hanger 1, a ring 2 and a bottom plate 3. The hanging buckle 1 is a member used to tie the lifting wire rope. The inverted U-shaped hanging buckle 2 is made of steel plate. At the same position at both ends of the opening side, there are respectively horizontal rectangular through-holes 1.1. The rectangular through-holes 1.1 are connected by chains. One of the basic components. In order to further improve the flexibility of the chain connection, the cross-section of the bottom edge of the rectangular through hole 1.1 in this embodiment is arc-shaped, and the specific shape is shown in figure 2 . The buckle 2 is a semicircular steel fastener with a rectangular cross section. The bottom plate is a rectangular steel plate, the two ends of the long side walls a...

Abstract

The invention discloses a hinged lifting appliance which comprises a lifting buckle, a ring buckle and a baseplate, wherein an inverted U-shaped steel component serves as the lifting buckle; transverse rectangular through holes are correspondingly formed in the similar positions of both ends of the open side of the lifting buckle; a rectangular steel plate serves as the baseplate; open grooves along the thickness direction are correspondingly formed in both ends of the long-edge side walls of the baseplate; a through hole penetrating through the plate surface of the baseplate is formed in the middle of the plate surface; a semicircular steel component serves as the ring buckle; the ring buckle penetrates through the rectangular through hole; both ends of the ring buckle span the baseplate and are embedded in the open grooves; and the ring buckle and the baseplate are fixedly connected at the junctions, thereby forming a lifting buckle and baseplate hinged-connection structure. The hinged lifting appliance disclosed by the invention adopts the hinged-connection structure; the degree of freedom among all the components is relatively high; when the lifting buckle is deflected, pre-embedded bolts of a lifted main building component can be conveniently mounted and dismounted by using a tool; and accordingly, the mounting and dismounting work efficiency can be improved.

Description

technical field [0001] The invention relates to a hanger, in particular, the invention relates to a hanger used for hoisting building components, especially a hanger adopting a hinge connection structure. Background technique [0002] In order to reduce the amount of urban construction waste and dust, the government strongly advocates the use of prefabricated construction techniques for new buildings. The prerequisite for the implementation of this construction process is that the main building components used must be factory-produced, and the prefabricated components are transported to the construction site for assembly installation. Due to the relatively large volume and heavy weight of the main building components of the formed house, lifting equipment must be used for installation. The hoisting position of the main building components is usually equipped with embedded bolts, which can be hoisted after connecting the embedded bolts with a spreader. The existing hanger i...
