Abstract
The invention discloses a plugging device for a cable tube hole and a mounting method thereof. The plugging device comprises a hollow sealing round plate, wherein a U-shaped jack is formed in the hollow sealing round plate, and an arc insert corresponding to the U-shaped jack is arranged on the hollow sealing round plate in a clamping and matching manner; and the hollow sealing round plate comprises a first round plate layer, wherein the first round plate layer is connected with a second round plate layer through a bolt, and a fire clay layer is placed between the first round plate layer and the second round plate layer. According to the plugging device for the cable tube hole and the mounting method thereof, the structure of the device is simple, the operation is convenient, a tube hole wall and a cable can be effectively sealed through fire clay, and thus water proofing and fire proofing of the cable are guaranteed.
Description
Technical field
The present invention relates to a kind of plugging device and installation method thereof of cable pore, relate in particular to wearing pore plugging device and the installation method thereof of cable.
Background technology
Along with urban development, overhead wire occupation of land shortcoming many, not attractive in appearance, that fail safe is low is also outstanding all the more, and the use proportion of cable can be more and more higher.But because cable is embedded in the missile silo for a long time, the rising of level of ground water, the situations such as accumulation of rainwater can cause that the cable shaft inner product is waterborne to rise, and make also to be full of ponding in the cable duct, reduce cable useful life and electric network security greatly.
So need carry out shutoff to the cable shaft pore, guarantee that each cable shaft inner product water does not connect mutually, guarantee the pipeline ponding not between the well simultaneously.Comparatively ripe to cable shaft blank pipe blocking technology at present, but to wearing the pore shutoff of cable, there is not effective, easy, low-cost apparatus to carry out shutoff so far.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of plugging device and installation method thereof of cable pore, it is simple in structure, and is easy to operate, and anti-chamotte can effectively seal pore wall and cable, thereby guarantees cable waterproof, fire prevention.
The present invention is the purpose that reaches above-mentioned, and the present invention adopts following technical scheme:
A kind of plugging device of cable pore comprises the hollow sealing plectane, and described hollow sealing plectane offers U-shaped socket, and described hollow sealing plectane engaging is equipped with the arc plug-in unit corresponding with U-shaped socket; Described hollow sealing plectane comprises the first plectane layer, and the described first plectane layer links to each other with the second plectane layer by bolt, is placed with the fire prevention mud layer between the described first plectane layer and the second plectane layer.
The diameter of the described first plectane layer is less than the diameter of the second plectane layer.
A kind of installation method of plugging device of cable pore comprises the steps: that the one side of the first plectane layer at first is towards the cable pore; Then cooperate U-shaped socket the cable fastening with the arc plug-in unit, and simultaneously hollow sealing plectane and plug-in unit are put into the cable tube hole; By the locking fastening bolt, drive the first plectane layer and the second plectane layer is drawn close mutually then, and then the fire prevention mud layer of filling in the middle of the extruding, thus after the expansion of fire prevention mud layer will with pore wall, the closely knit installation that contacts plugging device of cable.
Beneficial effect of the present invention is: the invention provides a kind of plugging device and installation method thereof of cable pore, it is simple in structure, and is easy to operate, and anti-chamotte can effectively seal pore wall and cable, thereby guarantees cable waterproof, fire prevention.
Description of drawings
Fig. 1 is the structural representation of invention;
Fig. 2 is the left view of Fig. 1 hollow sealing plectane.
Embodiment
As shown in Figure 1, 2, present embodiment provides a kind of plugging device of cable pore, comprises hollow sealing plectane 1, arc plug-in unit 2, and wherein said hollow sealing plectane 1 offers U-shaped socket 14; Described plug-in unit 2 can be used with U-shaped socket 14.Described hollow sealing plectane 1 comprises the first plectane layer 11, and the described first plectane layer 11 links to each other with the second plectane layer 12 by 4 bolts 3.The diameter of the described first plectane layer 11 is less than the diameter of the second plectane layer 12.Be placed with fire prevention mud layer 13 between the described first plectane layer 11 and the second plectane layer 12.
When the plugging device of the described cable pore of present embodiment uses, at first the one side of the first plectane layer 11 is faced the cable pore.Because the diameter of two plectanes is all less than the cable tube bore dia of required shutoff, and therefore the diameter of the first plectane layer 11 form a vertebral body structure less than the diameter of the second plectane layer 12, and assurance device is put into the cable pore smoothly.Then cooperate U-shaped socket 14 the cable fastening with arc plug-in unit 2, and simultaneously hollow sealing plectane 1 and plug-in unit 2 are put into the cable pore.By fastening 4 bolts 3, drive the first plectane layer 11 with the second plectane layer 12 is drawn close mutually then, and then the fire prevention mud layer 13 of filling in the middle of the extruding, after fire prevention mud layer 13 expands, will be with the pore wall, cable is closely knit contacts, thus assurance cable waterproof, fire prevention.
Plugging device and the installation method thereof of the described a kind of cable pore of present embodiment, it is simple in structure, and is easy to operate, and anti-chamotte can effectively seal pore wall and cable, thereby guarantees cable waterproof, fire prevention.
