Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the withstand voltage pipe close of cable duct bank of the present utility model.
In above accompanying drawing: 1, seal ring; 2, end casing; 3, standing screw; 4, set screw nut; 5, filling tube; 6, valve; 7, position-limited lever; 8, screw rod is installed.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: shown in accompanying drawing 1, in a kind of comb that is arranged at cable passage engineering, for its end being carried out to the withstand voltage pipe close of cable duct bank of shutoff, comprise body, seal ring 1, axially locating assembly, limit assembly and operating component.
It is more flat cylindrical that body is, and it is made by elastic material (as rubber etc.), and the inside of body is formed for filling in the injection pot of filler.The central axis of this body axially and its want axially the paralleling of cable duct bank of shutoff.
Seal ring 1 is also made by elastic material, and it is sheathed in the circumferential exterior surface of body and this circumferential exterior surface is covered completely, makes cannot directly see body by the outer surface of the withstand voltage pipe close of this cable duct bank.The external diameter of seal ring 1 and the internal diameter of comb match, place, the medial axis plane that it is annular and body axially perpendicular.The annular ridge design on the outer surface that sealing ring 1 contacts with comb inwall with frictional force between many inwalls that increase itself and comb.
Axially locating assembly is for limiting the relative position at the two ends of body on it is axial.Can adopt various structures to realize above-mentioned functions, for example, axially locating assembly comprises that the end casing 2 at a pair of axial two ends that are divided into body and several are fixedly connected on two fixed connecting pieces between end casing 2.Concrete, end casing 2 is the circle identical with the cross section of body, can adopt the glass fibre reinforced plastic material of hard to make, and two end casings 2 make the circumferential exterior surface of body between the two.Fixed connecting piece for through injection pot, connect pair of end cover plate 2 standing screw 3, match and merge the set screw nut 4 be positioned at end casing 2 outsides with standing screw 3.In the present embodiment, adopt four standing screw 3 and eight set screw nuts 4 that are uniformly distributed on end casing 2, on each standing screw 3, be equipped with two set screw nuts 4, these two set screw nuts 4 lay respectively at two end casing 2 outsides and by end casing 2 with body is clamping is integrated.
Injection pot need to have coupled logical material feeding port, and this material feeding port can be arranged on the middle position of an end casing 2, adopts a filling tube 5 along the axial setting of body.Material feeding port place need to have the valve 6 of controlling its unlatching or closing, and this valve 6 is arranged on filling tube 5.
Limit assembly is arranged on an end casing 2, and it is installed on comb position for limiting the withstand voltage pipe close of cable duct bank.In the present embodiment, limit assembly comprises that two symmetries are installed on the position-limited lever 7 on end casing 2, and this position-limited lever 7 is L-shaped.For simplicity, one end of position-limited lever 7 is directly connected in the end of two symmetrical standing screws 3 and is shaped to one with standing screw 3, make the part and the end casing 2 that on position-limited lever 7, are connected with end casing 2 perpendicular, another part parallels with end casing 2.In the part paralleling with end casing 2 on position-limited lever 7, have its other end, this end protrudes from the external diameter of seal ring 1.
Operating component is for connection instrument when by the withstand voltage pipe close of setting tool installing cables comb.In the present embodiment, operating component comprises the installation screw rod 8 for being connected with setting tool by screw thread being arranged on end casing 2, and for simplified structure, this can be installed to the end that screw rod 8 is directly integrated in two standing screws 3 that are not provided with limit assembly.
Above-mentioned filling tube 5, limit assembly and mounting assembly are positioned on the end casing 2 of the same side, and when the withstand voltage pipe close of this cable duct bank is installed in the end of comb, this end casing 2 with limit assembly and mounting assembly need be towards this end.First, by setting tool, the withstand voltage pipe close of cable duct bank is pushed to the end of comb, finally makes position-limited lever 7 be stuck in the edge of comb end, prevent the withstand voltage pipe close of cable duct bank to push position excessively dark.Then by material feeding port, to filling in filler in injection pot, force body to its circumferential expansion, body further forces seal ring 1 also to extend out, thereby seal ring 1 is closely pressed on the inwall of comb.Highly preferred scheme is, by compressor to fill in injection pot a kind of can be after solidifying the dilatable special cement of volume starch and make to reach in injection pot certain pressure intensity.Along with solidifying of cement slurry, its volume expands gradually, thereby forces body and seal ring 1 synchronously to the inwall of comb, to expand.In above-mentioned process of filling in filler, axially locating assembly can prevent that body from expanding on axially at it, and only in its week, upwards expands.When needs are removed the withstand voltage pipe close of this cable duct bank, first by screw thread, setting tool is fixed on and is installed on screw rod 8, then pull setting tool can realize the dismounting of the withstand voltage pipe close of cable duct bank.
This cable duct bank is withstand voltage, and pipe close can realize and the fitting tightly of comb inwall, thus by cable duct bank shutoff reliably, and can bear larger pressure, reach a series of functions such as waterproof, fire prevention, anti-mud, anti-foreign material.It can be in 2-3 Reusability, aging speed is slower, can reach more than 20 years total service life.Meanwhile, it is convenient to dismounting, for later stage cable laying and maintenance are provided convenience.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
