Abstract

A pipe mending device relates to a device for mending pipes with punched holes on oil field. In prior art, a general switches on head and tail of the pipes with punched holes are usually shut down when the pipes are punched and the mending work is usually done after the shut-down, which influences production and reduces operational efficiency. The utility model is designed to provide a mending device which does not have to be shut down while mending the pipes with punched holes, including a support shaft (1), vertical through holes (1-2) arranged on the support shaft (1) and a horizontal beam (1-1), wherein, a screw rod (2) penetrates through the through hole (1-2) and connects to the horizontal beam (1-1) by means of threads; the lower end of the screw rod (2) is provided with a press cap (2-1) with an arch bottom; the lower end of the two vertical shafts (1-3) of the support shaft (1) is provided with a connection chain (3). The utility model addresses the problems related to shut-down, which is simple in structure, convenient and fast in operation, thereby improving operational efficiency of oil fields.

Description

The pipeline repairing apparatus

Technical field: the utility model relates to the device that is used to repair the perforation pipeline that uses on a kind of oil field.

Background technique: at the field produces scene, pipeline is owing to be subjected to factor affecting such as heavy corrosion or artificial destruction, oil transportation often appears, waterline perforation phenomenon, at present after the pipeline perforation, normally close master valve in the top and the terminal of perforation pipeline, stop production, treat that line pressure drops to no longer and when guest performer's water, could go up electrogas welding, carry out the mending-leakage operation, it exists influence and produces, reduce the disadvantage of working efficiency, and in the mending-leakage process, can only weld with the built-up welding mode, it exists is waste material, shortens the shortcoming in welding machine life-span again, and because oil field tubulars weldering number is limited, and workload is big, in the perforation high-incidence season, can cause large size to stop production because having little time repair welding, thereby greatly reduce working efficiency.

The model utility content: the purpose of this utility model is to provide a kind of need the stopping production can repair the repairing apparatus of perforation pipeline, it comprises pole 1, on the crossbeam 1-1 of pole 1, be provided with longitudinal hole 1-2, leading screw 2 pass through hole 1-2 and with crossbeam 1-1 by being threaded, lower end place at leading screw 2 is provided with pressure cap 2-1, the bottom surface of pressure cap 2-1 is curved, and the lower end place of two montant 1-3 of pole 1 is provided with connection chain 3.Use device of the present utility model to press maybe needn't to be depressured under the normal pressure situation and can temporarily block site of perforation not reducing pipe, weld again at a convenient time, it has solved the problem that in emergency circumstances causes stopping production, it is simple in structure, convenient to operation, thereby has improved the working efficiency in oil field.

Structural representation when description of drawings: Fig. 1 is the utility model use, Fig. 2 is a structural representation of the present utility model.

Embodiment: present embodiment comprises pole 1, on the crossbeam 1-1 of pole 1, be provided with longitudinal hole 1-2, leading screw 2 pass through hole 1-2 and with crossbeam 1-1 by being threaded, the upper tip place of leading screw 2 is connected with rotating handles 4, lower end place at leading screw 2 is provided with pressure cap 2-1, the bottom surface of pressure cap 2-1 is curved, is connected with rubber sheet gasket 5 on the bottom surface of pressure cap 2-1, and the lower end place of two montant 1-3 of pole 1 is provided with connection chain 3.

The working procedure of this device is as follows: the position and the pipeline punch position of leading screw 2 are aligned, by connection chain 3 pole 1 is fixed on the pipeline to be repaired, drive leading screw 2 along through hole 1-2 rotation decline by screwing rotating handles 4 then, the punch position that the pressure cap 2-1 that is arranged on leading screw 2 lower ends props up pipeline gets final product, the bottom surface of pressure cap 2-1 is an arc, lower arcuate surface can better and wait to repair the pipeline fitted seal, be provided with rubber sheet gasket 5 on the bottom surface of pressure cap 2-1, rubber sheet gasket 5 plays the effect of better sealing pipeline perforation.

Claims (3)

1, a kind of pipeline repairing apparatus, it comprises pole (1), it is characterized in that on the crossbeam (1-1) of pole (1), being provided with longitudinal hole (1-2), leading screw (2) pass through hole (1-2) and with crossbeam (1-1) by being threaded, be provided with pressure cap (2-1) at the lower end place of leading screw (2), the bottom surface of pressure cap (2-1) is curved, and the lower end place of two montants (1-3) of pole (1) is provided with connection chain (3).

2, pipeline repairing apparatus according to claim 1 is characterized in that the upper tip place of described leading screw (2) is connected with rotating handles (4).

3, pipeline repairing apparatus according to claim 1 is characterized in that being connected with rubber sheet gasket (5) on the bottom surface of pressure cap (2-1).
