Example eight:
according to a second aspect of the present invention, a method for lifting an overturning device is also provided, which is used for the overturning device provided in any one of the technical solutions of the first aspect.
Fig. 8 shows a schematic flow chart of a lifting method of an apparatus for transferring molds according to the present invention, as shown in fig. 8, the method includes:
step 702: fixing at least two layers of formworks and pouring concrete into the formworks;
step 704: separating at least one layer of template below the uppermost layer of template from the connecting piece and moving the template to the position above the uppermost layer of template based on the strength of the concrete being greater than or equal to the strength threshold value;
step 706: and fixing the moved template.
In the technical scheme, all the formworks are fixed on the connecting pieces, concrete is poured between the formworks and a steel structure in the ladle concrete, and when the strength of the concrete is greater than or equal to a strength threshold value, the turning-up operation can be carried out, wherein the connecting pieces corresponding to at least one layer of formwork below the uppermost formwork are disassembled, namely the formworks are separated from the connecting pieces, the formworks separated from the connecting pieces are moved to the uppermost formwork, the formworks are further fixed, and then the turning-up process is completed.
Specifically, in the overturning and lifting process, at least the uppermost formwork is kept still to support the overturned and lifted formwork. Wherein, the connecting piece plays fixed effect to the template, and the concrete after reaching the intensity threshold value also plays certain supporting role to the template, and then has guaranteed the stability of structure.
Specifically, the strength threshold may be set according to actual conditions, for example, the strength of the concrete can support the weight of at least one layer of formwork and/or the weight of a constructor, and the value range of the strength threshold may be any value from 15MPa to 70MPa, or other values smaller than 15MPa or larger than 70 MPa.

fig. 9 shows a schematic flow chart of a lifting method of an apparatus for transferring molds according to the present invention, as shown in fig. 9, the method includes:
step 802: pre-burying at least one layer of pre-buried parts corresponding to the template;
step 804: fixing the template according to the fastener and the embedded part of the turnover equipment;
step 806: pouring concrete into the template;
step 808: installing the rest formworks in at least two layers of formworks above the formworks based on the strength of the concrete being more than or equal to the strength threshold, and pouring concrete into the rest formworks;
step 810: separating a support of the rollover equipment from a body of the rollover equipment to retract an operating platform of the rollover equipment;
step 812: separating at least one layer of template below the uppermost layer of template from the connecting piece and moving the template to the position above the uppermost layer of template based on the strength of the concrete being greater than or equal to the strength threshold value;
step 814: connecting the support piece with the body to support an operating platform of the turnover device;
step 816: and fixing the moved template.
In the technical scheme, before the formwork is lifted, the operation platform is retracted to make the inner space of the cylindrical ladle concrete available, so that the formwork is conveniently lifted, and particularly, the movement of the formwork can be realized by retracting the operation platform in a narrow space; after the formwork movement is completed, the work platform is again erected for the placement workers to stand on to pour concrete.
In the technical scheme, when at least two layers of templates are fixed, the lower template can be fixed firstly, concrete is poured between the template and the steel structure after the template is fixed, when the strength of the concrete reaches a strength threshold value, for example, when the strength of the concrete is enough to support at least one template, other templates in the at least two templates are installed above the template, and the concrete is poured continuously to ensure the stability of the structure, and further, after the at least two templates are installed for the first time, the template lifting operation is carried out after the lower template reaches the demolding strength.
