Abstract
A lifting device for a flange, comprising: the bolt structure is arranged on the main hoisting point structure, wherein the upper end of the main hoisting point structure is an arc-shaped main hoisting point plate, a groove is arranged below the main hoisting point plate, and a pair of locking arc plates are oppositely arranged in the groove; and a plurality of bolt holes for the bolt structures to pass through are arranged on the locking arc plate. The utility model has simple structure and convenient operation; the hoisting efficiency of the large-diameter flange is greatly improved by 30 percent; moreover, the loss of the hanging strip is greatly reduced, and the hoisting quality of the large-diameter flange is improved.
Description
Technical Field
The utility model relates to a hoist device especially relates to a hoist device for major diameter flange. Belongs to the field of ocean engineering.
Background
In the prefabrication link of the pipe connecting flange of the pressure container, the hoisting operation of the large-diameter flange is often met, and the existing generally adopted methods are two, wherein the first method is to directly hoist by using a lifting belt to penetrate through a bolt hole of the flange; the second method is that bolts penetrate through bolt holes of the flange, hanging belts are sleeved under the bolts, then the flange is erected, a plurality of operators hold the flange, another bolt penetrates through the flange, and then the hanging belts are hung on two sides of the flange for hoisting. By the operation method, the hanging strip is greatly abraded, and when an operator holds the hanging strip, the flange is easy to incline, so that personal injury of the operator is caused.
SUMMERY OF THE UTILITY MODEL
The main purpose of the utility model is to overcome the above disadvantages of the prior art, and to provide a flange hoisting device, which not only solves the hoisting problem of the large diameter flange, but also greatly improves the hoisting efficiency of the large diameter flange; moreover, the safety problem of hoisting the large-diameter flange is solved, the loss of the hanging strip is greatly reduced, and the hoisting quality of the large-diameter flange is improved.
The utility model aims at being realized by following technical scheme:
the utility model provides a hoist device of flange which characterized in that: the method comprises the following steps: the bolt structure is arranged on the main hoisting point structure, wherein the upper end of the main hoisting point structure is an arc-shaped main hoisting point plate, a groove is arranged below the main hoisting point plate, and a pair of locking arc plates are oppositely arranged in the groove; and a plurality of bolt holes for the bolt structures to pass through are arranged on the locking arc plate.
And the upper middle part of the main hoisting point plate is provided with a hoisting hole for a hoisting cable to pass through.
The bolt structure includes: the screw rod, install the nut on the screw rod.
The utility model has the advantages that: the utility model adopts the technical proposal, the structure is simple, and the operation is convenient; the hoisting efficiency of the large-diameter flange is greatly improved by 30 percent; moreover, the loss of the hanging strip is greatly reduced, and the hoisting quality of the large-diameter flange is improved.

Detailed Description
As shown in fig. 1, the utility model comprises: a main hoisting point structure 1, a bolt structure 2 mounted on the main hoisting point structure 1, wherein,
as shown in fig. 2, the upper end of the main hoisting point structure 1 is an arc-shaped main hoisting point plate 11, a groove is arranged below the main hoisting point plate 11, and a pair of locking arc plates 2 are oppositely arranged in the groove by welding; the locking arc plate 2 is provided with a plurality of bolt holes (two in the embodiment) for the bolt structures 2 to pass through.
The upper middle part of the main hoisting point plate 11 is provided with a hoisting hole for a hoisting cable to pass through.
As shown in fig. 3, the bolt structure 2 includes: a screw 21, and a nut 22 mounted on the screw 21 in a threaded manner.
As shown in fig. 4, when in use, two holes on the locking arc plate 12 of the present invention are corresponding to two holes on the flange, then two screws 21 are inserted, and then the nuts 22 installed on the screws 21 are tightened; after the fixing, the hoisting rigging is used to penetrate into the main hoisting point structure 1, so that the hoisting operation can be carried out.
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.
