Abstract
A flange lifting tool comprising: the lifting hook comprises a base, a plurality of reinforcing rib plates arranged on the base and lifting lugs arranged on the base, wherein a plurality of bolt holes used for the lifting hook to penetrate through are formed in the base. The utility model not only avoids the problem of sling abrasion caused by flange hoisting operation with the sling, but also greatly enhances the safety of flange hoisting; moreover, the problem that bolts are prevented from being penetrated and installed by lifting with a lifting belt when the flange vertical pipe is assembled is avoided, and the efficiency of assembling the flange is greatly improved.
Description
Technical Field
The utility model relates to a lifting device especially relates to an instrument for flange hoist and mount, belongs to the ocean engineering field.
Background
At present, the flange is usually hoisted by adopting a hoisting mode of penetrating and installing a hanging strip. However, in the hoisting mode, the problem that the flange cuts the sling is solved, and in the process of hoisting a single pipe containing the flange, the hoisting mode of penetrating the double sling is adopted, so that the consumed time is long; meanwhile, when the flange vertical pipe is paired, the hanging strip is adopted, the hanging strip can also prevent the bolt from penetrating and assembling, and the flange pairing is difficult to realize.
SUMMERY OF THE UTILITY MODEL
The main object of the utility model is to overcome the above disadvantages of the prior art, and to provide an improved flange hoisting tool, which not only solves the problem of sling abrasion caused by flange hoisting operation with a sling, but also greatly enhances the safety of flange hoisting; moreover, the problem that bolts are prevented from being penetrated and installed by lifting through a lifting belt when the flange vertical pipe is assembled is solved, and the efficiency of assembling the flange is greatly improved.
The utility model aims at being realized by following technical scheme:
the utility model provides a flange lifting's instrument which characterized in that: the method comprises the following steps: the lifting hook comprises a base, a plurality of reinforcing rib plates arranged on the base and lifting lugs arranged on the base, wherein a plurality of bolt holes used for the lifting hook to penetrate through are formed in the base.
The base is an arc-shaped plate matched with the flange neck, and the base is horizontally arranged.
The plurality of reinforcing rib plates are vertically arranged below the base at certain intervals.
The lifting lugs are arranged above the base, and radial reinforcing rib plates are vertically arranged on two sides of the lifting lugs.
The lifting hook is in a bolt type and is composed of a plurality of bolt and nut pairs.
The utility model has the advantages that: by adopting the technical scheme, the utility model not only avoids the problem of sling abrasion caused by flange hoisting operation by using the sling, but also greatly enhances the safety of flange hoisting; moreover, the problem that bolts are prevented from being penetrated and installed by lifting with a lifting belt when the flange vertical pipe is assembled is avoided, and the efficiency of assembling the flange is greatly improved.

Detailed Description
As shown in fig. 1-5, the present invention includes: the lifting device comprises a base 1, a plurality of (three in the embodiment) reinforcing rib plates 2 arranged on the base 1 in a welding mode, and lifting lugs 3 arranged on the base 1 in a welding mode, wherein the base 1 is provided with a plurality of bolt holes for the lifting hooks 4 to pass through.
Above-mentioned base 1 is the arc that matches with the flange neck, and base 1 is the level setting.
The plurality of reinforcing rib plates 2 are vertically arranged below the base 1 at certain intervals to avoid deformation of the base 1 during hoisting.
The lifting lugs 3 are arranged above the base 1, and radial reinforcing rib plates 5 are vertically arranged on two sides of the lifting lugs 3 in a welding mode so as to adapt to heavy-weight hoisting.
The hook 4 is in a bolt type and is composed of a plurality of bolt and nut pairs. During the use, the bolt is worn out through the reservation bolt hole on the base 1, and after the nut was twisted to the bottom, it was fixed with nut and base 1 adoption welding mode, and the top of bolt is equipped with reserve nut as required for when asymmetric hoist and mount, with nut locking, prevent hoist and mount in-process flange and fall.
The utility model discloses can be used to the flange hoist and mount of following different scenes:
(1) as shown in fig. 2, the single flange is horizontally hoisted: adopt two groups the utility model discloses symmetrical hoist and mount is applied to the flange and shifts or with the riser group to the work in.
(2) As shown in fig. 3, the single flange is vertically hoisted: adopt singly organize the utility model discloses carry out unilateral hoist and mount, be applied to the flange and shift or with horizontal pipeline group to the work in.
(3) As shown in fig. 4, hoisting the prefabricated single pipe containing the flange: adopt two groups the utility model discloses, two side hoists are applied to and contain the dislocation of the prefabricated single tube of flange or horizontal group to in the work.
(4) As shown in fig. 5, the vertical pair of prefabricated single pipes containing flanges is paired: adopt two groups the utility model discloses, the symmetry is hoisted, is applied to perpendicular group to, when having solved suspender hoist and mount effectively, the suspender hinders the problem that the bolt wore the dress.
The above-mentioned lifting lug 3 is prior art, and the technology that has not been explained is prior art, so it is not repeated.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
