Abstract
The utility model relates to a petrochemical trade filtering separation equipment field specifically is a removable blind flange lifts by crane and uses lug, including lifting by crane jib, bearing bolt, nut, lug, fixing bolt and blind flange, the lug passes through fixing bolt with the blind flange and is connected, it is connected through bearing bolt and nut with the lug to lift by crane the jib. The utility model has the advantages that: through the use of bearing bolt and fixing bolt, avoided the welding to arouse that the blind flange warp and lead to the problem of medium leakage, because the change can be dismantled to the lug in addition, improved the life of equipment.
Description
Technical Field
The utility model relates to a petrochemical trade filtering separation equipment field specifically is a removable blind flange lifts by crane and uses lug.
Background
Along with the development of chemical industry, filtering separation equipment is more and more used in petrochemical field, need open the flange lid of pressure vessel equipment when needing to change filtering separation equipment's internals, the lug for lifting by crane of structure in the past is welded connection with equipment flange lid, and its shortcoming is because welded connection, welding stress's existence makes the flange lid produce the deformation easily, arouses the medium to leak, and secondly because welded connection, the lug can not be dismantled and change, shortens equipment life.
In order to solve the above problems, engineers have devised some solutions. For example, utility model patent of granted publication No. CN 204079261U provides a novel detachable blind flange lug, and its structure comprises blind flange, lug board, round pin axle three, and the blind flange center sets up square through hole, makes things convenient for the lug board to pass, and the round pin axle is used for fixed lug board and blind flange. But the center of the flange cover needs to be provided with a square through hole, and the tightness of the device is affected. And the lug plate needs to be disassembled from the lower part, so that the disassembly is inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a removable blind flange lifts by crane and uses lug to solve the problem that mentions among the above-mentioned background art.
In order to realize the purpose, the technical scheme is as follows:
the utility model provides a removable flange cover lifts by crane and uses lug, includes lifting boom, carrier bolt, nut, lug, fixing bolt and flange cover, the lug passes through fixing bolt with the flange cover and is connected, lifting boom is connected through carrier bolt and nut with the lug.
Compared with the prior art, the beneficial effects of the utility model are that: through the use of bearing bolt and fixing bolt, avoided the welding to arouse that the blind flange warp and lead to the problem of medium leakage, because the change can be dismantled to the lug in addition, prolonged the life of equipment.
Drawings
FIG. 1 is an overall assembly structure view of a lifting lug;
fig. 2 is a schematic structural diagram of the lifting lug.
In the figure, the lifting hanger rod 1, the lifting hanger rod 2, the bearing bolt 3, the nut 4, the lifting lug 5, the fixing bolt 6 and the flange cover.
Detailed Description
The invention will be further explained and explained with reference to the drawings and examples.
Example (b): referring to fig. 1-2, a detachable lifting lug for lifting a flange cover comprises a lifting suspension rod 1, a bearing bolt 2, a nut 3, a lifting lug 4, a fixing bolt 5 and a flange cover 6, wherein during installation, the lifting lug 4 is connected with the flange cover 6 through the fixing bolt 5, and the lifting suspension rod 1 is connected with the lifting lug 4 through the bearing bolt 2 and the nut 3.
When the lifting lug is unloaded, only the bearing bolt 2 and the nut 3 need to be loosened, and then the fixing bolt 5 needs to be loosened.
