Abstract
The utility model relates to a pipeline maintenance tool, in particular to a removing device of an oil robbing clamp in a crude oil pipeline. The removing device comprises a manual tapping machine, a seal sleeve and an expansion bolt. The seal sleeve comprises a sleeve body and a pressing cap. The bottom of the sleeve body is provided with external threads, the upper portion of the sleeve body is provided with the pressing cap, the pressing cap is provided with a sealing gasket 3, a rubber pad is arranged between a bushing of the expansion bolt and a screw rod, the bushing of the expansion bolt is provided with external threads, and the inner side of the seal sleeve is provided with the expansion bolt. The removing device has the advantages that utilization is simple, efficiency is high, operation can be carried out under the condition that the pipeline is needless to be stopped conveying, the operation can be carried out on an oil conveying pipeline with high pressure, and due to the facts that the expansion bolt is short and cannot block the pipeline, safety coefficient in use is high.
Description
Technical field
The utility model relates to a kind of pipeline maintainance instrument, particularly a kind of crude oil pipeline stolen clamp removal device.
Background technique
Along with the Continued of crude oil price, crude oil pipeline destroys and is on the rise, and illegal stolen molecule employing is made the stolen clamp at transfer line and stolen crude oil, and they adhere to the stolen clamp on the crude oil pipeline with strong adhesive, carry out stolen with the paddle system of digging.The remedial measure that adopts at present is, with the Chinese ash bar fine away pound along the stolen hole afterwards into, again Chinese ash is amputated from root, this method causes pipeline to stop up because of the delay of wooden stick easily, and can not be used on the high pipeline of pressure; Another kind method is: crude oil shutdown, blow-down pipe is wasted time and energy and is delayed production.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of crude oil pipeline stolen clamp removal device is provided.
Its technological scheme is: comprise Manual tapping machine, seal sleeve, EXPANSION ANCHOR BOLTS, described seal sleeve is comprised of cylindrical shell, pressure cap, and the bottom of cylindrical shell is provided with outside thread, and the top of cylindrical shell is provided with pressure cap, and described pressure cap is provided with sealing gasket; Be provided with Rubber washer between the sleeve pipe of EXPANSION ANCHOR BOLTS and the screw rod, the sleeve pipe of EXPANSION ANCHOR BOLTS is provided with outside thread; The inside of seal sleeve arranges EXPANSION ANCHOR BOLTS.
The beneficial effects of the utility model are: use simply, efficient is high, can construct in the situation of pipeline without stopping transportation, can construct at the higher petroleum pipeline of pressure, because the short problem that does not therefore have blocking pipeline of EXPANSION ANCHOR BOLTS, the use safety coefficient is high.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of Manual tapping machine;
Among the upper figure: cylindrical shell 1, pressure cap 2, sealing gasket 3, Rubber washer 4, screw rod 5, sleeve pipe 6.
Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises Manual tapping machine, seal sleeve, EXPANSION ANCHOR BOLTS, and described seal sleeve is comprised of cylindrical shell 1, pressure cap 2, and the bottom of cylindrical shell 1 is provided with outside thread, and the top of cylindrical shell 1 is provided with pressure cap 2, and described pressure cap 2 is provided with sealing gasket 3; Be provided with Rubber washer 4 between the sleeve pipe 6 of EXPANSION ANCHOR BOLTS and the screw rod 5, the sleeve pipe 6 of EXPANSION ANCHOR BOLTS is provided with outside thread; The inside of seal sleeve arranges EXPANSION ANCHOR BOLTS.
During use, first seal sleeve is installed on the regulating gate of stolen clamp, then pass seal sleeve to the reaming tapping of stolen hole with Manual tapping machine, then extract Manual tapping machine, the closing control gate, with six rib setting tool EXPANSION ANCHOR BOLTS being passed cartridge cooperates with tapping hole on the pipeline, tighten, if still have overflow, then tighten interior six ribs, thereby with the rubber distending, pipeline is sealed up.
Can in the situation of pipeline without stopping transportation, construct, can construct at the higher petroleum pipeline of pressure, because the short problem that does not therefore have blocking pipeline of EXPANSION ANCHOR BOLTS uses safety coefficient high.
