Description
Technical field
The present invention relates to a kind of cable protections, more particularly, to a kind of cable protection pipe nozzle fire prevention calking bearing device.
Background technique
Organic fire prevention calking is mostly used to be blocked at cable protection pipe nozzle at present, organic fire prevention calking is with organic conjunction
It is bonding agent at resin, addition fireproof agent, filler etc. are formed through spreading.The putty does not solidify for a long time, and plasticity is fine, Ke Yiren
Blocked to meaning.The fire prevention calking is nontoxic, odorlessness, there is the performances such as preferable water-fast, oil resistant, fire resisting, and construction method is simple,
Adhesiveness is strong, can with a variety of materials close adhesion, meet fire after volume expansion, surface carbonation can occur, formed firm back-fire relief every
Thermosphere, to reach back-fire relief purpose.
But at present through investigation learn that ratio shared by fire prevention calking dropping situations is higher, existing security risk risk compared with
Greatly.Because cable protection pipe is stood up, fire prevention calking expanded with heat and contract with cold by downward gravity, and organic fire prevention calking under the conditions of with cable
Decline with the bonding force of protection pipe, it can partial exfoliation after general 3-6 months.
Such as Chinese patent notification number are as follows: CN205377205U, on July 6th, 2016, a kind of cable protection of bulletin was effective
Bearing device, including drum type brake ontology, fixinig plate and several support pieces, device closure length is too short, and rain and snow weather can be made
At penetrating into many water in penetration pipe, while when the excessive hydraulic pressure of ponding is excessive, fire prevention calking can be rushed to open, and caused to block and be failed；If
Fire prevention calking is clogged excessive, although solving the problems, such as to leak and gone out by ponding, will cause when backup line investment makes
The stifled mud of used time, filling are difficult to take out, while causing the uneconomical of cost.

Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
In embodiment 1: Fig. 1, limit film 3 is bent downwardly, and the gap with bearing device ontology 1 is with bearing device ontology 1
Inside and outside wall thickness is adapted, and bearing device ontology 1 adjusts the cylindrical shape for curving adaptation according to cable protection pipe caliber size, is had more
Be partially submerged into limit film 3 with the gap location of bearing device ontology 1, effective fixed and limit can be carried out to bearing device ontology
Position, 2 upper end of fixed ring is bent downward, links closely and protects pipe outer wall, prevent bearing device from gliding, support circle 4 is far from axis
The upward bending in one end is stop collar 11, and the angle of 4 bending part of support circle is acute angle, and 5 bottom end of waterproof cover is prevented on support circle 4
5 outer wall of water cover is the conical surface, can be more effectively to the waterproof cover of the conical surface when angle of 4 bending part of support circle is acute angle
Bottom limit.As can be seen from FIG. 6, bearing device ontology 1, fixed ring 2, limit film 3, support circle 4 are structure as a whole.
From the figure 3, it may be seen that the side expanded view of waterproof cover 5 is fan annular, several limits are provided on 5 upper end side wall of waterproof cover
Position hole 9, is additionally provided with the limited post 10 matched with limit hole, is truncated cone-shaped when being assembled by Fig. 4, waterproof cover 5 can be according to outside cable
Wall diameter carries out telescopic adjustment, and the limited post 10 from matching with limit hole fixes waterproof cover with being clamped with limit hole 9
5, prevent waterproof cover 5 arbitrarily mobile, it is in mating connection according to Fig. 7 and connection type shown in Fig. 8 and support circle 4.
There is opening in 7 side of prop drum type brake ontology, according to the size of cable outer diameter, by prop drum type brake
Ontology 7 completes the tubular that is sized for, is close to cable outer wall, with surrounding on the side wall of 7 upper end of prop drum type brake ontology
The axis of prop drum type brake ontology 7 is provided with several interval troughs 12, and the part between two neighboring interval trough 12 is to hold
Supporting spring 6, support piece 6 are inserted into the card slot 8 of 1 lower end of bearing device ontology and are clamped with card slot, beyond clamping is partially bent downwardly, make
Prop does not fall, and cannot partially be inserted into the support piece of card slot when top is to bearing device inner body wall beyond being partially turned under
Folding, the wall thickness length of an interval slot length support piece bigger than the length of other half interval trough for the support piece of half, works as electricity
When cable outer diameter is too small, prop drum type brake ontology can be avoided between the support piece of overlapping positions during molding
Interference is generated, is adjusted convenient for prop, several support pieces form to hold up the support plane of fire prevention calking.
When cable protection nozzle carries out fire prevention calking closure, fire prevention calking is inserted into cable protection pipe nozzle fire prevention calking
In bearing device, whole device plays integrated support to fire prevention calking, and fire prevention calking can be prevented to glide along protection inside pipe wall,
Waterproof cover is adjusted according to cable outer diameter size again, is adapted with support circle, effective waterproof action can be played.
It should be understood that being somebody's turn to do, examples are only for illustrating the present invention and not for limiting the scope of the present invention.In addition, it should also be understood that,
After having read the content of the invention lectured, those skilled in the art can be made various changes or modifications the present invention, these
Equivalent form is also fallen within the scope of the appended claims of the present application.
