Abstract

The utility model relates to a safety hanging tool for lifting a pipeline, which comprises a hanging tool body in a hook shape. A hook arm, a hook head and a hook bottom are connected with each other to form an integral structure, and the hook arm and the hook head are perpendicular to the hook bottom. A connecting hole is arranged at the upper end of the hook arm, and a shackle is arranged in the hole and provided with a safety steel wire rope. The hook bottom is provided with a notch so as to protect a pipeline groove. After the pipeline lifting safety hanging tool is adopted, during vertical and inclined lifting and anchoring process of the pipeline, the hanging tool is tightly fixed below the pipeline, safety accidents caused by pipeline fall caused by slide or drop of the steel wire rope are avoided. In addition, completeness of the pipeline groove is effectively guaranteed. Simultaneously, the pipeline lifting safety hanging tool is simple in structure, capable of being used for pipelines of different specifications, economical and safe.

Description

A kind of insurance hanger that is used for the pipeline lifting

Technical field

The utility model relates to building operation hoisting and hanging device, particularly a kind of insurance hanger of pipeline lifting safety.

Background technology

At present; The specification of building operation industry such as thermal powerplant pressure piping, material and weight strengthen along with the increase of generating set power; The lifting risk of pipeline also strengthens thereupon, the particularly vertical and lifting of tilting of pipeline, the no any stop block in hoisting wirerope top; And do not allow to weld interim ironware on the pipeline, bring the danger of sliding or falling easily.The employing that has that pipe clamp is installed on pipeline is anti-skidding, but pipe clamp is made trouble, installation requirement is high, is difficult for removing, and must be furnished with different pipe clamps to the pipeline of different size, construction cost strengthens.

The utility model content

To the problem that exists in the prior art; The utility model purpose is to provide a kind of insurance hanger that is used for the pipeline lifting, and it can prevent effectively that pipeline insurance steel cable in vertical, the tilt lifting and the process of casting anchor from sliding and bring dangerous and protect tube groove excellent effectively.

To achieve these goals; The utility model adopts following technical proposals: a kind of insurance hanger that is used for the pipeline lifting, comprise the hanger body, and said hanger body is hook-type; Form an integral structure by interconnecting at the bottom of hook arm, gib head and the hook, and hook arm and gib head are all perpendicular at the bottom of the hook; Connecting bore is established in said hook arm upper end, the Kong Zhongshe shackle, said unload to buckle establish insurance steel cable.

In order to protect tube groove, be provided with breach at the bottom of the hook of the utility model, the shape of breach is decided according to the shape of tube groove.

The preferred version of such scheme is that said breach is located at and is positioned at the bottom of the hook and gib head intersection.

According to the construction needs, what shape tube groove is, at the bottom of the hanger hook on corresponding position also be designed to the breach of respective shapes.Existing most of pipe design becomes single V-butt, so breach is designed to be positioned at the bottom of the hook and gib head intersection at the bottom of the hanger hook, and upper surface shape linearly at the bottom of the hook, breach is triangular in shape, and its base angle is the 30-60 degree.Like tube groove is two V-arrangements, and the upper surface is oblique line shape at the bottom of the hanger hook of the utility model, and breach is the triangle that is positioned at the bottom of the hook with gib head intersection; Like tube groove is U-shaped, and at the bottom of the hanger hook of the utility model the upper surface is circular arc, and breach is the triangle that is positioned at the bottom of the hook with gib head intersection.

In order to make hanger be stuck in difficult drop-off on the pipeline, the gib head upper end is not less than 100mm with upper surface distance at the bottom of the hook.

Can know by technique scheme; After adopting this insurance hanger that is used for pipeline lifting, in vertical, the tilt lifting and the pipeline process of casting anchor, hanger is fixed on pipeline tightly; Avoid the slip or the landing of insurance steel cable that pipeline is fallen, caused safety misadventure; Guarantee the integrity of tube groove on the other hand effectively, be convenient to the progress of the welding and the follow-up work of pipeline.Simultaneously this pipeline lifting safety device is simple in structure, can be used on the pipeline of different size, and not only economy but also safety are brought very big convenience to lifting.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify.

Fig. 1 is hanger body embodiments one scheme drawing of the utility model;

Fig. 2 is hanger body embodiments two scheme drawings of the utility model;

Fig. 3 is hanger body embodiments three scheme drawings of the utility model;

Fig. 4 is the utility model elevation profile erection plan when being used for pipeline and vertically lifting by crane;

Fig. 5 is the utility model elevation profile erection plan when being used for pipeline and tilting lifting.

Among the figure: 1-hook arm, at the bottom of the 2-hook, 3-gib head, 4-connecting bore, 5-breach, 6-hanger body, 7-shackle, 8-insurance steel cable, 9-pipeline, 10-crane hook.

The specific embodiment

Embodiment one

As shown in Figure 1, hanger body 6 is hook-type, by hook arm 1, gib head 3 through at the bottom of the hook 2 connect in aggregates; Hook arm 1 and gib head 3 are respectively with 2 vertical at the bottom of the hook; The upper surface is horizontal linear at the bottom of the hook, at the bottom of the hook 2 with gib head 3 intersections be provided with a vee 5, its base angle is the 30-60 degree.

Embodiment two

As shown in Figure 2, through 2 connecting in aggregatesly at the bottom of the hook, with 2 vertical at the bottom of the hook, the upper surface is oblique line shape to hanger body 6 at the bottom of the hook respectively for hook arm 1 and gib head 3 by hook arm 1, gib head 3, at the bottom of the hook 2 and gib head 3 intersections be provided with vee 5, adapt to double V-shaped tube groove.

Embodiment three

As shown in Figure 3, through 2 connecting in aggregatesly at the bottom of the hook, with 2 vertical at the bottom of the hook, the upper surface is circular arc to hanger body 6 at the bottom of the hook respectively for hook arm 1 and gib head 3 by hook arm 1, gib head 3, and 2 are provided with vee 5, adaptation U type tube groove with gib head 3 intersections at the bottom of the hook.

In above-mentioned three examples, the size of the size of hanger body 6 and breach 5 designs adjustment according to the size of pipeline and groove thereof, and in order to prevent hanger landing from the pipeline, the distance of 2 upper surfaces should be not less than 100MM at the bottom of its gib head 3 upper surfaces and the hook.In the connecting bore 4 of hanger body, establish shackle 7, unload to buckle and establish insurance steel cable 8.

Shown in Figure 4 is the utility model elevation profile erection plan when pipeline vertically lifts by crane, and Fig. 5 is the utility model elevation profile erection plan when pipeline tilts lifting.

Hanger body 6 is stuck on the mouth of pipe of pipeline 9, and the groove of pipeline 9 just in time embeds in the breach 5 on the hanger body 6, has protected the integrity of tube groove.Hanger body 6 is connected with shackle 7, and shackle 7 is connected with insurance steel cable 8, crane hook 10 again.

Be with tight insurance steel cable during lifting, the hanger body just steadily is fixed on pipeline at the mouth of pipe, and hanger slides when preventing just to lift by crane, and can adopt artificial auxiliary method of helping this moment, treats can unclamp after the stressed tension of insurance steel cable.Pipeline hangs behind the ground owing to receive the tractive of hanger, and the lifting insurance steel cable will can not slide.

These embodiment are not limited only to the protection domain of the utility model, all based on the basic thought of the utility model and make amendment or the protection domain that all belongs to the utility model that changes in.
