Abstract
The invention discloses a power pipeline plugger. The power pipeline plugger is characterized in that the power pipeline plugger is provided with a cylindrical elastic rubber body of which the outer end and the inner end are closed, axial bearing plates with sliding sleeves are embedded in the outer end and the inner end of the elastic rubber body respectively, an inner thread is arranged in the sliding sleeve at the inner end of the elastic rubber body, a center through hole is formed in a position closing plate, one end of a screw rod penetrates through the center through hole in the plate closing plate, the sliding sleeve at the outer end of the elastic rubber body is connected with the thread of the sliding sleeve at the inner end of the elastic rubber body and stretches out of the sliding sleeve at the inner end of the elastic rubber body, and the other end of the screw rod is provided with a rotating handle. When the power pipeline plugger is used, the elastic rubber body is inserted through an opening of a power transmission pipeline so that the position closing plate can be close to the wall of the opening of the power transmission pipeline, the rotating handle is rotated clockwise, the screw rod pulls the elastic rubber body to contract, the middle of the elastic rubber body is pressed to expand in the radial direction and closely make contact with the pipeline wall, and therefore the plugging function is achieved. The power pipeline plugger has the advantages of being compact in structure, easy to operate, convenient to use and the like and can be widely applied to plugging power supply pipelines, heating pipelines, cable television pipelines, communication pipelines and other pipelines.
Description
Technical field
The present invention relates to transmission line facility, specifically a kind of simple to operate, threading convenient, prevent transmit electricity electric wire, cable corrosion and aging power pipe plugging device.
Background technology
We know, in order to safety and the transmission of electricity pollution of minimizing ground of transmitting electricity, the electric wire paving of city with good conditionsi transmission of electricity, be hung in down blow tunnel, ground, but all pre-buried power transmission mode of great majority, pre-buried power transmission mode is the transmission line ditching in planning, being embedded in by the power transfer conduit that transmission of electricity electric wire is housed is embedded in ditch in ditch or by power transfer conduit, the connection of electric wire or cable is carried out again from the two ends of power transfer conduit, in maintenance or when setting up circuit, also the extraction of electric wire is carried out from the two ends of power transfer conduit, the operations such as insertion, existing power transfer conduit port is without special plugging device, general employing is greater than coiling electric pipe shutoff by position of the pipeline mouth of pipe, or adopt cloth or paper to fill in power transfer conduit port to carry out simple shutoff, enter power transfer conduit to prevent water and corrosion is caused to electric wire, prevent from silt particle from entering to result in blockage to power transfer conduit, to the replacing of electric wire, penetrate and cause inconvenience.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of compact conformation, simple to operate, can the power pipe plugging device of available protecting power transfer conduit and interior electric wire thereof.
The technical solution adopted for the present invention to solve the technical problems is.
A kind of power pipe plugging device, be provided with and coil by position, it is characterized in that being provided with tubular elastic rubbery body that is outer, interior closed at both ends, external, the interior two ends of elastic caoutchouc are embedded with the axial force bearing disk of band sliding sleeve respectively, the inner sliding sleeve of elastic rubbery body is provided with internal thread, be provided with center through hole by position dish, one end of leading screw is connected and the inner sliding sleeve of elasticity of extension rubber bodies with the inner sliding sleeve screw thread of elastic rubbery body through by position dish center through hole, elastic rubbery body outer end sliding sleeve, and the other end of leading screw is provided with rotating handle.
The inner sliding sleeve end of leading screw elasticity of extension rubber bodies of the present invention is provided with the pin-and-hole perpendicular to leading screw axis, is provided with locking pin in pin-and-hole, to prevent leading screw from coming off from the inner sliding sleeve of elastic rubbery body, makes its work more reliable.
The present invention can have packing ring and be drilled with dowel hole by cover in elastic rubbery body, on the leading screw of elastic rubbery body outer end sliding sleeve, is provided with alignment pin, to make its reliable operation in dowel hole.
When the present invention uses, the model adapted is selected according to the bore of power transfer conduit, elastic rubbery body is inserted by electroduct road junction and makes to press close to electroduct road junction wall by position dish, rotate clockwise rotating handle, leading screw is made to pull elastic rubbery body to shrink, the middle part pressurized of elastic rubbery body and radial expansion and with tube wall close contact, thus realize the function of shutoff, when need repairing or newly-increased electric wire time, rotate counterclockwise rotating handle, leading screw is made to pull elastic rubbery body to stretch, the middle part tension of elastic rubbery body and radial expansion, depart from power transfer conduit wall, easily elastic rubbery body is taken out again through rotating handle, there is compact conformation, simple to operate, the advantage such as easy to use, power supply can be widely used in, heating and cable TV, the shutoff of the pipelines such as communication.
