Abstract

The utility model discloses a structure of an inflating bag type pipeline threading device. A conical pipeline plug is made, and the bottom part of the pipeline plug is provided with an arc surface loading wind. The pipeline plug is put in an inflating bag which is made of plastic thin film, the front part of the external shape of the inflating bag forms a streamline shape, the rear part of the inflating bag is provided with air inlets, and the tail end of the inflating bag is provided with a connecting thread hole which is connected with a piece of penetrating and leading thread. When the utility model is used, the inflating bag is plugged in pipeline, compressed air is blown in the pipeline, under the push of a gas stream, the inflating bag and the arc surface loading wind of the pipeline plug pull the penetrating and leading thread to go down to the other end of the pipeline. Because the inflating bag softly contacts the inner diameter of the pipeline, the utility model is particularly suitable for threading engineering of bending pipeline.

Description

A kind of inflation pocket type Penetrating wire for pipe device

The utility model relates to the Penetrating wire for pipe device, particularly a kind of inflation pocket type Penetrating wire for pipe device.

Electric wire, fiber optic cables being penetrated long-distance pipe, lead to the user, is a kind of work of difficulty.Adopt at present a duct plug, the back be guide line, with high pressure draught duct plug is moved forward in pipeline, reach the purpose that pipeline connects electric wire, fiber optic cables.The shortcoming of the said equipment is that the duct plug diameter must adapt with internal diameter of the pipeline, so versatility is poor, and when work duct plug big with the internal diameter of the pipeline resistance, especially in the place of pipe bending, more be difficult to construct.

The purpose of this utility model is at above-mentioned shortcoming, and a kind of inflation pocket type Penetrating wire for pipe device is provided, because air bag contacts with internal diameter of the pipeline is soft, applicability is extensive, and resistance is little, can be with the flexural deformation of pipeline, and work is convenient.

The purpose of this utility model is achieved in that

Make a conical duct plug with light material, the bottom of duct plug forms one to internal recess and carries the wind cambered surface.Duct plug is put into the air bag of a plastic film system, and air bag profile front portion is streamlined, and there is 1 to 10 air inlet at the rear portion, and tail end has the line hole, and connects line and is connected.

Select the duct plug that is slightly less than internal diameter of the pipeline during use for use, put into air bag, air bag tail end tighten connects line.Air bag is filled in the pipeline, noted the conical top of duct plug forwards.Beginning is blown into compressed air in pipeline.Air-flow enters the inside of air bag from the air inlet of air bag, makes air bag and duct plug concave bottom carry the wind cambered surface under the promotion of air-flow, marches forward smoothly in pipeline, hauls to connect line until the other end of pipeline, finishes the threading task of pipeline.

Owing to adopt the utility model, rely on air-flow to promote air bag, duct plug concave bottom and carry the pulling of marching forward of wind cambered surface and connect line, simple to operate, the special threading work that adapts to complicated crooked pipeline.Solved the problem that pipeline connects line loop operation difficulties such as electric wire, fiber optic cables.

In conjunction with the accompanying drawings and embodiments, further describe structure of the present utility model.

Fig. 1 is the schematic diagram of the utility model structure;

Fig. 2 is the schematic diagram that the utility model is worked in bend pipe.

Among the figure: 1, duct plug, 2, conical top, 3, carry the wind cambered surface, 4, air bag, 5, air inlet, 6, connect line, 7, pipeline.

Embodiment:

Make a conical duct plug (1) more smaller than internal diameter of the pipeline with light material, the bottom of duct plug (1) forms one to internal recess and carries wind cambered surface (3).Duct plug (1) is put into fusiform air bag (4) of a plastic film system, and there are 4 air inlets (5) at air bag (4) rear portion, the line hole of air bag (4) tail end with connect line (6) and be connected.

During use duct plug (1) is put into air bag (4), whether tighten connects line (6) to check air bag (4) tail end.Air bag (4) is filled in the pipeline (7), noted the conical top of duct plug (1) (2) forwards.In pipeline (7), be blown into compressed air.Air-flow enters the inside of air bag (4) from the air inlet (5) of air bag (4), make air bag (4) and duct plug (1) concave bottom carry wind cambered surface (3) under the promotion of air-flow, in pipeline (7), march forward smoothly, haul and connect the other end of line (6), finish the threading task of pipeline (7) up to pipeline.

Claims

1, a kind of inflation pocket type Penetrating wire for pipe device, it is characterized in that: make a conical duct plug (1) with light material, the bottom of duct plug (1) forms one to internal recess and carries wind cambered surface (3), duct plug (1) is put into the air bag (4) of a plastic film system, air bag (4) profile front portion is streamlined, there is 1 to 10 air inlet (5) at the rear portion, and tail end has the line hole and connects line (6) and be connected.
