Detailed Description

In the following, in order to facilitate the understanding of the technical solutions of the present utility model by a person skilled in the art, reference will be made to the accompanying drawings for further description. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model.

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

As shown in fig. 1, the double-hook X-shaped variable-pitch four-pile jacket hanger is a schematic overall structure diagram and comprises a main cross beam 1, four groups of inclined beams 2 and four groups of end beams 3. In the concrete implementation, the main beam 1, the oblique beam 2 and the end beam 3 are all of variable cross section box type steel structures. Wherein, main beam 1 both ends top is equipped with sling 4, and four groups of sloping 2 are whole to be arranged and are X shape and set up in main beam 1 both sides through the bolt symmetry, and four groups of end beam 3 are respectively through bolt fixed connection between four groups of sloping 2 and main beam 1, and the one end and the sloping 2 of every group of end beam 3 keep away from the one end connection of main beam 1, and the other end is connected perpendicularly on main beam 1.

The X-shaped variable-pitch four-pile jacket lifting appliance for the double hooks has the advantages that the four groups of inclined beams are arranged on the main beam in an X shape, the end beams are arranged between the main beam and the inclined beams, and all the beam bodies are connected through the bolt groups.

As shown in fig. 2, in the present embodiment, a plurality of lower suspension holes 5 for connecting the lower suspension wires 6 are uniformly arranged at the bottom of the inclined beam 2.
