Abstract
The utility model discloses a rotary-hanging plugging head with a dual leather cup, which comprises a guiding push plate and a support that is articulated with the guiding push plate, wherein the end part of the support is fixedly connected with a plugging leather cup; the plugging leather cup consists of a main leather cup and an auxiliary leather cup that are arranged in the same direction; a main support plate that is arranged at a cup bottom of the main leather cup is connected with a connection plate arranged in the auxiliary leather cup into a whole by a hinge shaft; an auxiliary support plate is fixedly connected with the cup bottom of the auxiliary leather cup; the guiding shaft of which one end is fixedly connected with the auxiliary support plate extends upwards in an inclined manner; and a guiding wheel is arranged at the end part of the guiding shaft. The rotary-hanging plugging head with the dual leather cup has the advantages that the structure is simple; the operation is flexible; the plugging effect is good; particularly when an oil gas pipeline is plugged, the main leather cup and the auxiliary leather cup are matched with each other for use, the main leather cup faces towards an impact medium directly, and small leakage at a gap of the edge is plugged again by the auxiliary leather cup, so that the purpose of dual-plugging at one time is achieved; labor and material resources are saved greatly; the safety is improved greatly; and the engineering time is shortened.
Description
Technical field
The utility model relates to pipe plugging spare, especially relates to the double leather cup rotating hanging block head of a kind of once two envelopes, the tight ne-leakage of obstruction.
Background technique
Pipeline (comprising aqueduct, gas pipeline, oil transport pipeline etc.) often needs temporary plugging in construction, maintenance or checking process, namely under the complete airtight state of pipeline, transform the both sides of pipeline section at need, utilize the physical mechanical means that the section of transformation is isolated stifled disconnected from pipeline, it is safeguarded, repairs or replacing etc.The physical mechanical means comprise a plurality of forms such as a barrel formula shutoff, suspension type shutoff.Operating pipeline relocated be divided into that stopping transportation is relocated and the stopping transportation dual mode of relocating not: stopping transportation is not relocated and normally the section of relocating both sides is connected with bypass tube respectively, with the bypass line fed sheet of a media, and shutoff main line then; It generally is with pipeline shutdown that stopping transportation is relocated, and utilizes method for blocking that the section of relocating and main line is stifled disconnected, empties the interior medium of the section of relocating, and cuts off old pipeline section, with new pipeline section for it.
Treating when transforming pipeline section and carrying out shutoff, usually adopt shutoff air bag or plugging leather cup to carry out shutoff.When treating that blocking pipe is that weldless tube and pressure medium are when little, plugging effect is all right, if pipeline (particularly oil and gas pipes) is on volute or the pipeline weld bond to be arranged, when plugging leather cup entered the interior shutoff of pipeline, the weld bond place was often because shutoff is not tight, the medium Seepage appears, run into when pressure medium is larger in the pipe, can increase the weight of seepage, can not carry out next step and connect head work, in case and seepage does not sternly appear in the oil and gas pipes shutoff, just may there be the danger of blast.Common processing mode is to open a lower bag hole again and carry out secondary plugging with connecting in the middle of the head place in shutoff, and this solution need to expend very large man power and material, and has prolonged the construction period.
Summary of the invention
The double leather cup rotating hanging block head that provides a kind of plugging effect better, safer is provided the purpose of this utility model.
For achieving the above object, the utility model can be taked following technical proposals:
Double leather cup rotating hanging block head described in the utility model, comprise the guiding push pedal and be hinged on support in the described guiding push pedal, described bracket end is fixed with plugging leather cup, described plugging leather cup is comprised of the primary cup and the secontary cup that arrange in the same way, is arranged on the main support plate at the bottom of the primary cup bowl and the connecting plate that is arranged in the secontary cup bowl and is connected as a single entity by hinge; Be fixed with secondary support plate at the bottom of described secontary cup bowl, the axis of guide that an end is connected on the secondary support plate extends setting obliquely upward, and its end is provided with upper saw pulley.
Be provided with roller on the described hinge.
Described main support plate, secondary support plate and treat that the point of contact place of blocking pipe inwall is provided with pulley.
The utility model has the advantage of simple in structure, flexible operation, plugging effect is good, particularly during the shutoff oil and gas pipes, major and minor leather cup is used, and primary cup is directly in the face of impact media, and the minor leakage at place, slit, edge is carried out again shutoff with secontary cup, realized the once purpose of two envelopes, save a large amount of human and material resources, greatly improved Security, shortened engineering time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
As shown in Figure 1, 2, double leather cup rotating hanging block head described in the utility model, comprise guiding push pedal 1 and the support 2 that is hinged in the guiding push pedal 1, support 2 ends are fixed with plugging leather cup, for improving the leakproofness of shutoff, plugging leather cup is comprised of the primary cup 3 and the secontary cup 4 that arrange in the same way, is arranged on the main support plate 5 at the bottom of 3 bowls of the primary cups and the connecting plate 6 that is arranged in 4 bowls of the secontary cups is connected as a single entity by hinge 7; Be fixed with the axis of guide 9 that secondary support plate 8, one ends are connected on the secondary support plate 8 and extend obliquely upward setting at the bottom of 4 bowls of secontary cups, its end is provided with upper saw pulley 10.For reducing block head and treating frictional force between the blocking pipe inwall, be provided with roller 11 in hinge 7 central positions; Frictional force before and after being to reduce between leather cup and the inner-walls of duct, the flexibility when increasing shutoff is at main support plate 5, secondary support plate 8 and treat that the point of contact place of blocking pipe inwall is provided with pulley 12.
During work, guiding push pedal 1 externally moves downward under the hydraulic power effect, and the upper saw pulley 10 of the axis of guide 9 ends of eccentric setting is done transverse movement in pipeline under the promotion of guiding push pedal 1; The thereupon 11 contact inner-walls of duct of the roller on the hinge 7 and relatively center line, do same transverse shifting, the edge of secontary cup 4 is attached on the inner-walls of duct, finish the shutoff of secontary cup 4, guiding push pedal 1 continues downwards, the primary cup edge gradually close, attach on the tube wall, guiding push pedal 1 is finished the shutoff of primary cup 3 to pipe during the end.Plugging leather cup is pressed in mould by materials such as butadiene acrylonitrile rubbers and is formed type, can anti-middle high-pressure, and after shutoff was finished, guiding push pedal 1 externally proposed pipelines with primary cup 3 and secontary cup 4 under the acting in opposition of hydraulic power successively.
