Description
Technical field
The utility model relates to a kind of expansion mold for cool condensing electric cable accessories.
Background technology
Cold shrinking power cable adjunct (motor cable annex) has the features such as volume is little, easy to operate, product specification is few.For 35kV and following cold shrinking power cable adjunct, generally adopt both at home and abroad and before dispatching from the factory, complete expansion (generally expand on stay pipe: the cylindrical support pipe of certain length is made up of narrower plastics strip winding welding, put into the cable accessory after expansion, then progressively be pulled away from one end of plastics strip after removing stay pipe, cable accessory just wraps and is fixed on cable).
China Patent Publication No. is: CN103419169A, disclose " cold shrinking power cable adjunct dilator and practical approach thereof ", the outer wall of the dilatation mold of this cold shrinking power cable adjunct dilator is the double-decker for air-flow conducting, dilatation mold is provided with charging connector away from one end of conehead, dilatation mold is provided with several pores near one end of conehead, and pore is around dilatation mold outer surface circular array.This dilatation mold is by arranging the mode of pore; the gas of pore ejection can carry out slight expansion to the cold shrinking power cable adjunct in flexible fabric cover and flexible fabric cover outside; gap between increase dilatation mold and flexible fabric overlap; avoid flexible fabric to overlap and produce fold and dilatation mold generation hard friction; prevent flexible fabric from overlapping wearing and tearing; flexible fabric cover is protected, extends the service life of flexible fabric cover and whole dilator, reduce to change the cost needed for flexible fabric cover.
But, owing to needing the dilatation mold adopting different tube diameters size for different cylindrical support pipes in real work, and the dilatation mold of this cold shrinking power cable adjunct dilator in the annexation of body is: dilatation mold is fixedly connected with connecting rod away from one end of conehead, and hydraulic jack is connected with dilatation mold by connecting rod.This connected mode directly causes a cold shrinking power cable adjunct dilator can only expand a kind of cold shrinking power cable adjunct of pipe diameter size.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of structural design simple, rational expansion mold for cool condensing electric cable accessories.
The technical scheme in the invention for solving the above technical problem is: a kind of expansion mold for cool condensing electric cable accessories, comprise the double-layer barrel of straight tube-like and be plugged on the conical head on double-layer barrel top movably, described double-layer barrel comprises inner barrel and outer cylinder body, there is between described inner barrel and outer cylinder body ventilation cavity, and be provided with passage on the top of described double-layer barrel, it is characterized in that, also comprise pedestal, described pedestal is hollow cylindrical structure, is respectively equipped with through hole one and through hole two at the end face of described pedestal and bottom surface; The bottom of described inner barrel is connected with described through hole two fitted seal, and the bottom of described outer cylinder body is connected with described through hole one fitted seal, described pedestal is provided with air admission hole and communicates with described base interior and cavity of ventilating.
Further, dome shape is made on the top of described conical head of the present utility model.Effectively prevent flexible fabric from overlapping and hard friction and cause flexible fabric to overlap easily wearing and tearing between conical head.
Further, multiple jack is provided with in the bottom surface of described pedestal of the present utility model.Be convenient to the connection with cold shrinking power cable adjunct dilator body.
The utility model compared with prior art, have the following advantages and effect: double-layer barrel combines with the structure of pedestal by the utility model, overlap avoiding flexible fabric and produce fold and dilatation mold generation hard friction, prevent flexible fabric from overlapping on the basis of wearing and tearing, for the double-layer barrel needing the replaceable corresponding pipe diameter size of cold shrinking power cable adjunct expanding different tube diameters size, overall construction design is simple, reasonable, answer the variation of right cold shrinking power cable adjunct product, decrease the manufacturing cost of cold shrinking power cable adjunct dilator, improve production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1-Fig. 3, the present embodiment comprises conical head 1, the double-layer barrel 2 of straight tube-like and pedestal 3 from top to bottom successively.
Dome shape is made on the top of this conical head 1, conical head 1 is plugged on the top of double-layer barrel 2 movably, double-layer barrel 2 comprises inner barrel 21 and outer cylinder body 22, there is between inner barrel 21 and outer cylinder body 22 ventilation cavity 23, be provided with six equally distributed passages 24 of horizontal direction on the top of double-layer barrel 2, this passage 24 communicates with ventilation cavity 23.
Pedestal 3 is hollow cylindrical structure, is provided with through hole 1 at the end face of pedestal 3, and bottom surface is provided with through hole 2 32; The bottom of inner barrel 21 is connected with through hole 2 32 fitted seal, and the bottom of outer cylinder body 22 is connected with through hole 1 fitted seal, pedestal 3 is provided with air admission hole 33 and communicates with pedestal 3 inside and cavity 23 of ventilating; Multiple jack 34 and the grafting of cold shrinking power cable adjunct dilator body is provided with in the bottom surface of pedestal 3.
The operation principle of the present embodiment is: inflated to air admission hole 33 by air pump, and gas is first even in pedestal 3 internal mix, then discharges from passage 24 through ventilation cavity 23; Dilatation mold can be made to change by pedestal 3 convenient, to adapt to the cold shrinking power cable adjunct of different tube diameters requirement.
