Abstract

The invention relates to a device for clearing an obstruction in a bent pipeline in a drawing mode and a using method thereof. The device is characterized in that: a pair of gears (4) is driven by a screw rod (8) pulled by a mild steel wire column (7) arranged in the conventional metal snakeskin hose (5) through positive and negative rotation force of a handle (6) to control a pair of gripper arms (9) to open and close, so that the obstruction (1) in the pipeline (2) is gripped. The using method comprises the following steps of: making the conventional metal snakeskin hose (5) penetrate into a position with the obstruction (1) in the pipeline (2), opening the gripper arms (9) through positive rotation of the handle (6) and pushing the gripper arms (9) to a peripheral position with the obstruction (1) in the pipeline (2); closing the gripper arms (9) to clamp the obstruction (1) through negative rotation of the handle (6); and drawing the conventional metal snakeskin hose (5) or/and the handle (6) to take the obstruction (1) out of the pipeline (2). The device is suitable for pipeline engineering, particularly the conventional maintenance work of sewerage engineering.

Description

Remove the device and the using method thereof of crooked pipeline obturator by drawing mode

Technical field:

The present invention relates to a kind of devices and methods therefor of removing the crooked pipeline obturator by drawing mode.

Technical background:

At present, all be by obturator being stirred after the pine, adopting the mode of pushing that its another outlet from pipeline is discharged again for the reset mode of pipeline obstruction thing.If pipeline does not have another outlet, or another outlet is far, and again not for getting rid of the position that this removes for example large space pipe joint of thing stacking, so, above-mentioned pipeline obstruction thing just is difficult to get rid of in the middle of it.

People adopt the single armed hook to hook up ducted obturator, it also is a kind of method of a kind of short distance (it is very near to leave the mouth of pipe) obturator from critical point drawing pipeline, but, owing to be subjected to the restriction of pipeline space, in narrow and small pipeline, because the single armed hook is difficult to adjust to the suitable position that hooks up, make the obturator that hooked up in hooking up the way, break off relations with above-mentioned single armed hook, be difficult to reach the purpose of removing the pipeline obstruction thing.

Summary of the invention:

The objective of the invention is:

A kind of devices and methods therefor of removing the crooked pipeline obturator easily by the mode of pincers thing and drawing (not being pushing) is proposed.

In order to realize the object of the invention, intend adopting following technology:

Structural entity form of the present invention and type of drive thereof comprise:

Positive and negative turn by handle affects screw mandrel to implement the conventional mechanism of the positive and negative rotation of driven wheel, it is characterized in that:

A. be provided with a pair of chela on the direction outwardly on the above-mentioned a pair of gear, open and the closure of this a pair of chela is the direction of rotation that is controlled by above-mentioned screw mandrel;

B. implement to drive by one stone dead wire post between above-mentioned screw mandrel and the handle;

C. above-mentioned conventional mechanism is arranged in the middle of the common metal snakeskin hose.

The related step that comprises of using method of the present invention is as follows:

D. at first, the common metal snakeskin hose is deep into the position that obturator is arranged in the pipeline, by the dextrorotation of handle, allows chela be in open configuration, and this chela is urged to the peripheral position that obturator is arranged in the pipeline;

E. then,, allow chela block obturator, or/and handle, can should from pipeline, take out by ducted obturator by this common metal snakeskin hose of drawing with the state that closes up by the derotation of handle.

Characteristics of the present invention:

Owing to, allow the above-mentioned a pair of chela of setting up implement the pincers of pipeline internal congestion thing are got the condition created for reaching by dextrorotation or derotation screw mandrel at a pair of chela that is provided with on the above-mentioned a pair of gear on the direction outwardly; Simultaneously, because common metal snakeskin hose of the present invention can be crooked, and it uses the value of length is to design appreciablely, and this has just created condition again for increasing substantially practicality of the present invention.

Description of drawings:

State when Fig. 1 has illustrated the present invention's closure.

State when Fig. 2 has illustrated that the present invention opens.

1: obturator; 2: pipeline; 3: gear shaft; 4: gear; 5: the common metal snakeskin hose; 6: the handle screw mandrel; 7: one steel wire post that constitutes by many steel wires that is used to export positive and negative rotary torsion; 8: screw mandrel (bolt); 9: chela.

The specific embodiment:

Get an external diameter and be about 5 centimeters common metal snakeskin hoses 5 (belong to can be stressed on its length direction that a kind of) that are about 5 meters, in an end of this common metal snakeskin hose 5 (gear 4 being installed in the transition mechanism that is positioned above-mentioned flexible pipe 5 ends by gear shaft 3) a pair of gear 4 that tooth is arranged at least is set according to conventional method on the one semi-circumference, and in the welding of the front end position of this a pair of gear 4 a pair of chela 9, in order to vise the obturator 1 in the pipeline 2 easily, the pincers thing end of this a pair of chela 9 should be the crotch shape that faces toward in opposite directions; Drive the screw mandrel 8 of this a pair of gear 4, with between the handle 6 of power output by one steel wire post 7 (for example :) of constituting by many steel wires by the 30 1 millimeter thick tied cylinder that forms of straight type elastic wire as transition piece (can be connected) by welding or other usual manner, this measure purpose is: even if under the crooked to some extent situation of common metal snakeskin hose 5, the rotary torsion of staff on handle 6 also is the rotation that can one crooked steel wire post 7 drive screw mandrel 8 by this.---common setting is: when by handle 6 when left-handed, this a pair of chela 8 moves towards open direction, is convenient to put in the periphery of obturator 1; When by handle 6 dextrorotation, this a pair of chela 9 promptly towards the direction operation of closure, is used to vise obturator 1.

During use, at first, the present invention is deep into the position that obturator 1 is arranged in the pipeline 2, just can allows screw mandrel 8 drive a pair of gear 4 and open and allow them put in the periphery of obturator 1 by left-handed with hand; Then, by handle 6 dextrorotation and allow this a pair of gear 4 drive these a pair of chelas 8 towards the direction operation of closure and vise obturator 1; At last, as long as the present invention is extracted out along former road from pipeline 2, can finish whole from pipeline 2 interior work of removing obturator 1.

Illustrate a bit:

The present invention's the foregoing description structurally belongs to five-star version, if, often needing in the pipeline 2 of straight type during the liftoff removing of short distance obturator 1, the present invention structurally fully can be with the simplest frame mode design:

As long as common metal snakeskin hose that will be wherein 5 adopts the straight type tube material of stereoplasm tube that is worse than it to replace, and one stone dead wire post 7 wherein also adopts the rigid posts that is worse than it to replace to get final product.
