Abstract

The utility model provides a flange pipe hanger for lifting a flange pipe, the flange pipe hanger comprises a hanging ear, a shackle, and a nut, the hanging ear comprises a main body, a convex lug, and a screw, the convex lug and the screw respectively extend from the main body and in opposite directions, the convex lug is pivoted to the shackle, the screw can traverse the flange hole of the flange pipe and can be locked via the nut. The hanger in the utility model is advantageous in that the hanger adopts a special design, the angle between the hanging ear of the hanger and the shackle can be automatically adjusted, thereby guaranteeing the verticalness of the flange pipes when lifting flanges of different sizes, facilitating installation and placement, and improving work safety.

Description

The flanged pipe suspender

[technical field]

The utility model relates to suspender, relates in particular to a kind of suspender that is used to lift flanged pipe.

[background technology]

The large crossing tower of electric power transmission line and other industry high towers all more and more adopt the steel tube tower structure now, and promptly iron tower master limb or bottom material all are steel-tube construction, and the flange by the steel pipe two ends docks.The steel pipe that one or both ends are provided with flange is called flange tubing, abbreviates flanged pipe as, and the structure of flanged pipe as shown in Figure 1A and 1B.

When tube material is in horizontality in iron tower, can realize simple hoisted in position with common suspender belt.

When tube material is in attitude close to the vertical shape in iron tower, two kinds of traditional hanging methods are arranged.

A kind of is suspender belt (or steel rope) strapping, and details as shown in Figure 2.This hanging method has two significant disadvantages.At first, under the action of gravity of tubing, two Flange Plane are not in horizontality up and down, and this tubing docks with following pipe joint material when in place, and operation is difficulty relatively.Secondly, suspender belt contacts with upper flange plate seamed edge, is subjected to the scuffing of burr or sharp edges easily, even is cut off fully, therefore has very big potential safety hazard.

Another kind is common suspender method, and common suspender is processed by round steel, and its structure is as shown in Fig. 3 A.When using this common suspender lifting operation, with bolt suspender is fixed on the bolt hole on the flanged plate in pairs, is suspended under the hoist lifting hook by shackle and suspender belt, its using method as shown in Figure 4.

Common suspender hanging method though make up and down Flange Plane on even keel of tubing, makes tubing vertical substantially, has made things convenient in placely, and a significant disadvantages is also arranged.Be exactly under the tubing action of gravity, suspender is in the stressed bending of lower end meeting, as shown in Fig. 3 B.Because the pipe diameter difference, the size of the distribution diameter of the flanged plate upper bolt hole of flanged pipe end is also different, makes this suspender angle of bend (a angle shown in Fig. 3 B) when the different flanged pipe of lifting always change, the time little when big.This is equivalent to continuous positive and negative bending suspender bar, makes the very fast decline of suspender intensity, therefore has very big potential safety hazard.

[utility model content]

In view of this, be necessary to provide a kind of safe flanged pipe suspender.

A kind of flanged pipe suspender that is used to lift flange tubing, described flanged pipe suspender comprises hanger, shackle and nut, described hanger comprises main body, lug and screw rod, described lug and screw rod extend described lug and described screw rod from described main body to direction in opposite directions respectively, described lug is connected with described shackle pivotly, and described screw rod can pass the flange hole of flanged pipe and use described nut locking.

Preferably, offer on the described lug and shackle bonded assembly mounting hole.

Preferably, the diameter of described main body is greater than the diameter of described screw rod.

Preferably, described flanged pipe suspender also comprises hoist cable, and described hoist cable connects two described shackles.

Preferably, described flanged pipe suspender also comprises suspension hook, and described suspension hook is hooked on the centre of described hoist cable.

The utility model adopts the suspender of particular design, makes that the hanger of suspender and the angle between the shackle can automatic compensations, thus can both guarantee during the flanged pipe of lifting different size flanged pipe vertically, be convenient to installation in position, also improved the safety of operation.

[specific embodiment]

For understanding the utility model better, the embodiment to utility model is described in detail below with reference to accompanying drawing.

As shown in Fig. 5 to Fig. 7, flanged pipe suspender of the present utility model comprises hanger 10, shackle 20, pad 30, nut 40 and hoist cable 50.

See also Fig. 5 A to Fig. 5 C, hanger 10 comprises main body 12 and the lug 14 and the screw rod 16 that extend up and down of autonomous agent 12 respectively.Lug 14 is provided with fixed orifice 142, can be connected (as shown in Figure 6) with shackle 20, and shackle 20 is hanger 10 rotating certain angle relatively.The diameter of screw rod 16 is less than the diameter of main body 12.

See also Fig. 7, when using these hanger 10 lifting flanged pipes 70, in the flange hole of elder generation with two symmetries of the screw rod 16 insertion flanged pipes 70 of hanger 10, by pad 30 and nut 40 hanger 10 and flanged pipe 70 are coupled together again, with hoist cable 50 shackle 20 on two hangers 10 is linked up then.At last, with suspension hook 60 slinging with hoist cable 50.Angle between shackle 20 and the hanger 10 can tightening and automatic compensation along with hoist cable 50.

In the process of using the flanged pipe suspender to lift, flanged pipe 70 can remain vertical state, is convenient to installation in position.After the screw rod 16 of hanger 10 tightly was fixed on the flange hole of flanged pipe 70, because its screw rod 16 partial-lengths are short, under the action of gravity of flanged pipe 70, screw rod 16 parts can not found flexural deformation.

When the flanged plate change in size of flanged pipe 70, can its angles of inclination of automatic compensation with hanger 10 bonded assembly shackles 20, hanger 10 load-carrying capacitys are not weakened, thus construction safety has obtained powerful guarantee.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
