Abstract
Power transmission and transformation bin cable punching hole plugging device, relates to a kind of auxiliary equipment of cable laying construction, particularly belongs to the cable punching hole plugging device that the power transmission and transformation bins such as a kind of ring main unit, coupling box use.It is characterized in that, be formed by stacking with one heart by circular outer rim binder course (3), interlayer elastomer (2) ecto-entad; The elastomeric central authorities of interlayer are middle fastener hole (1), match with the outside diameter of cable; The axial end of outer rim binder course has shutoff glue-line (4), sticks barrier paper (5) outside shutoff glue-line.The utility model has simple to operation, time saving and energy saving, shutoff good airproof performance, cost-saving good effect.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of cable laying construction, particularly belongs to the cable punching hole plugging device that the power transmission and transformation bins such as a kind of ring main unit, coupling box use.
Background technology
Plastic plate after the cable plugging device that current domestic ring main unit, coupling box use generally all adopts cutting, steel plate add fire-proof mud and carry out shutoff, and it mainly exists following shortcoming:
1, material require scene processing during construction, wastes time and energy.Need to carry out cuts sheet material according to cable size, install after fixing and undertaken filling up hole by fire-proof mud again.
2, on-the-spot crudy depends on workman's sense of responsibility and technique, of low quality after construction.Due to processing difficulties, often there is not shutoff or the not tight situation of shutoff, for cable running safety bought hidden danger.
3, form of construction work causes potential safety hazard large.Plastic plate and steel plate cut too small, are easy to hurt cable, destroy cable outer layer sheath, and the situation of incised wound cable cold-shrinkable terminal annex even occurs, and potential safety hazard is very big.And the reserved oversize fire-proof mud that will cause is caved in lower leakage;
4, can not contract with cable synchronizing and rise, easily produce gap.Age hardening after the fire-proof mud time is long, the synchronous effect that rises that contracts can not be produced with cable, be easy to produce gap.
Utility model content
The purpose of this utility model is to provide a kind of novel power transmission and transformation bin cable punching hole plugging device, and to reach, structure is simple, easy to use, shutoff tight, reduce the object of potential safety hazard.
Power transmission and transformation bin cable punching hole plugging device provided by the utility model, is characterized in that, is to be formed by stacking with one heart by circular outer rim binder course, interlayer elastomer ecto-entad; The elastomeric central authorities of interlayer are middle fastener hole, match with the outside diameter of cable; The axial end of outer rim binder course has shutoff glue-line, sticks barrier paper outside shutoff glue-line.
Power transmission and transformation bin cable punching hole plugging device provided by the utility model, during use, cable is through middle fastener hole, after cable construction completes and fixes, plugging device is pulled down to power transmission and transformation bin cable punching hole position, pastes after the barrier paper strip off outside shutoff glue-line at the lower limb such as ring main unit, switch cubicle.The utility model has simple to operation, time saving and energy saving, shutoff good airproof performance, cost-saving good effect.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model cross-sectional view;
Fig. 2, the utility model vertical view.
Embodiment
As shown in drawings, power transmission and transformation bin cable punching hole plugging device provided by the utility model, ecto-entad is followed successively by outer rim binder course 3, interlayer elastomer 2 and middle fastener hole 1.At axis direction, at least one end face of outer rim binder course has shutoff glue-line 4, is barrier paper 5 outside shutoff glue-line, so as deposit with transportation in play a protective role.
The power transmission and transformation bin cable punching hole plugging device that the utility model provides, outer rim binder course combines with the interlayer elastomer in it, form an annular plugging device of concentric circles, middle fastener hole can be different according to cable model, and expand different sizes, common reserved telescopic extensions is diameter 2.0-10 cm scope, to meet the shutoff requirement of all common cable models.
Described interlayer elastomer, by resilientiy stretchable material, as rubber, nylon etc. are made, to ensure that middle fastener hole has suitable and lasting radial curable grip to cable, makes the two combine all the time closely.
The utility model has the following advantages:
1, construct simple and convenient.After only needing staff to be fixed through, cable from middle fastener hole by cable, then barrier paper bottom plugging device is torn bond.Do not need on-the-spot processing, intermediate course elastomer is reserved very big elasticity and is applicable to common all cable models.
2, construct not high to technological requirement, do not have the personnel of installation experience also can use, construction technology is unification simply, can not the not high problem of outlet construction quality.
3, without the hidden danger that incised wound cable, fire-proof mud are subsided.Because adopting elastic protective material, all use flexible materials in the middle of plugging device, damage can not be caused to cable jacket, body and annex.Do not use fire-proof mud, also need not consider that fire-proof mud is sunk problem.
4, intermediate course elastomer closes and is combined with cable body, synchronously contracts rise with cable body.Can not outlet because of cable contracting rise produce gap, tight shutoff can be accomplished.
