Abstract
The utility model discloses a box-type flange hanger, which is designed for realizing low-cost lifting of a large-sized reactor. The box-type flange hanger is characterized in that a blind plate of the hanger is a box-shaped structure and is formed by connecting an upper cover plate and a lower cover plate through a rib plate; corresponding welding plug slots which are connected with the rib plate and corresponding bolt holes are formed on the upper cover plate and the lower cover plate; symmetrical lug plate through holes are formed on the upper cover plate; the lug plate is connected with the lower cover plate after penetrating through the through holes; and a reinforced plate is arranged between the side of the lug plate and the end surface of the upper cover plate. The box-type flange hanger provided by the utility model is simple in structure, can be fabricated in construction site, is short in manufacturing period and low in processing low, and only 1/3 manufacturing cost of a forged false flange lug is used, so the cost of hoisting manufacturing can be effectively controlled. The box-type flange hanger provided by the utility model can realize lifting of an ultra-large reactor, and plays a role in promoting the development of reactor lifting technology.
Description
Technical field
The utility model relates to a kind of box flange suspension apparatus, belongs to the hoisting technology field.
Background technology
At present, the most of reactors that are widely used in the fields such as chemical industry, oil refining, metallurgy and light industry all adopt forging formula dummy-flange hoisted in position, and this forging formula dummy-flange manufacturing cost is high, and the process-cycle is long.
Summary of the invention
The purpose of this utility model is to provide a kind of box flange suspension apparatus, and this suspender is easily made, and cost is low, especially is fit to the lifting of large-scale reactor.
Concrete technical scheme of the present utility model is as follows:
The blind plate of the utility model suspender is box-structure, is formed by the link of boards lower cover by upper cover plate.
The upper cover plate lower surface is connected weldering plug groove corresponding, that connect gusset with the lower cover upper surface, be evenly equipped with corresponding bolt hole on upper cover plate and the lower cover.
Upper cover plate is provided with symmetrical shackle plate through hole, and shackle plate passes this hole and connects lower cover.Shackle plate is provided with the hanger plate hole, is provided with brace panel between shackle plate lateral surface and upper cover plate upper surface.
This box flange suspension apparatus is simple in structure, can make at the construction field (site), and the manufacturing cycle is short, and tooling cost is low, only for 1/3rd of forging formula dummy-flange hanger cost of manufacture, can effectively control the lifting construction expense.This box flange suspension apparatus can be realized the lifting of super large reactor, and impetus has been played in the development of reactor hoisting technology.

The specific embodiment
Further specify referring to figs. 1 through 4 couples of embodiment of the present utility model:
Embodiment:
The utility model box flange suspension apparatus is made of upper cover plate 1, lower cover 2, gusset 3, shackle plate 4, brace panel 5 etc.:
The blind plate of suspender is box-structure, and material adopts the Q-235B steel plate, connects lower cover 2 by upper cover plate 1 by gusset 3 and forms.
Being connected the upper surface and being equipped with weldering plug groove 8 corresponding, that connect gusset 3 in upper cover plate 1 lower surface with lower cover, is evenly equipped with corresponding bolt hole 6 on upper cover plate 1 and the lower cover 2.
The hanging method of this box flange suspension apparatus may further comprise the steps:
1, makes the box flange suspension apparatus
⑴, the perforate of box flange bolt hole must be consistent with the container top flange hole, and the deviation of chord length must not surpass ± 1mm between center circle diameter deviation and adjacent two holes, and the deviation of chord length must not surpass ± 1.5mm between any two holes;
⑵, assembly welding order must be in strict accordance with drawing constructions;
, the welding complete after, guarantee that deviations from planarity is 0.5mm;
⑷ coaxiality deviation must not surpass ± 2mm between, hanger plate hole;
, except specifying weld seam, other all weld seam full welds, the weldering height is thinner thickness in the two-phase weldment.
⑹ butt welded seam permeates detection after, the welding, and one-level is qualified.And to the shackle plate heat treatment that eliminates stress.
⑺, box flange suspension apparatus and reactor tie bolt need be joined in addition, and the parameters such as model and material are identical with formal tie bolt.
2, construction preparation
⑴ when installed the box flange suspension apparatus, tie bolt all used.
⑵ when tighted a bolt, the overall process unification was operated by three workmans.
⑶ adopt and knock the spanner fastening nut, guarantees all bolt strained even.
⑷ box flange suspension apparatus adopts two shackles to be connected with wire line hitch.
