Description
Technical field
The utility model relates to the gold utensil that a kind of power cable laying is used, and in particular, the utility model relates to a kind of power cable gold utensil that can retrain three cables simultaneously.
Background technology
Power cable tunnel is the requisite facility of urbanization process and power grid construction.In the past, power cable tunnel was generally rectangle, was power cable laying hereinto, adopted linear angle steel column and angle steel cross-arm usually, on single pair of cross-arm, set up power cable.In order to be applicable to that suspender installs, this moment, employed power cable gold utensil was generally the rectangle global shape, perhaps, was formed with on said gold utensil that size, bigger being used to of intensity are installed, the member of fastening bolt and lifting usefulness.Thus, cause power cable gold utensil volume bigger, floor space is also bigger.
Along with the rhythm of urbanization process and power grid construction is accelerated, the use of electric power tunnel is increasingly extensive.Therefore, laying also of power cable had higher requirement.
For example, along with the raising requirement of the volume installation of power cable, the power cable number that need be installed in the electric power tunnel is also increasing day by day.For dealing with the power cable of this increase, said power cable must overcome the pattern of linear installation in the past, optionally, in power cable tunnel, said power cable bending is installed.And rectilinear power cable gold utensil installation in the past can't be satisfied this requirement.
In addition, modern power cable tunnel extensively adopts circular tunnel, replaces the linear angle steel column and the angle steel cross-arm of installation power cable in the past, and the support that the power cable gold utensil is installed in the power cable tunnel has also adopted arc support.At this moment, continue to use big moment of volume shape gold utensil in the past to meet the demands, and reduce the space service efficiency of power cable tunnel.
The utility model content
The technical problem that the utility model will solve provides a kind of power cable gold utensil of small size, is convenient to install.
For solving above technical problem, the technical scheme of constraint power cable gold utensil is following in the middle of three cores of the utility model:
A kind of cable tunnel engineering is with constraint power cable gold utensil in the middle of three cores; Comprise simultaneously three power cables are retrained the main body of gold utensil up and down that grips; Said bottom gold utensil main body is connected the power cable anchor clamps that fit back formation one has the middle constraint of three cores cavity with top gold utensil main body; The constraint cavity is an entire cavity in the middle of said three cores, and the cross section of constraint cavity is " article " font structure in the middle of said three cores.
Cable tunnel engineering according to the utility model retrains the power cable gold utensil with three cores centre, and preferably, the place that said bottom gold utensil main body is connected with top gold utensil main body is that hinge connects.Another place connects for bolt.
Cable tunnel engineering according to the utility model retrains the power cable gold utensil with three cores centre, and preferably, gold utensil main body below in said bottom is provided with down the gold utensil firm banking.Base be provided with can be in needs bottoms use fixedly the time.
Further, on said down gold utensil firm banking, on the power cable direction, be formed with dish-shaped neonychium.
Cable tunnel engineering according to the utility model retrains the power cable gold utensil with three cores centre, and preferably, the cavity face of said bottom gold utensil main body is a matsurface.
In a preferred embodiment, said gold utensil forms different tubaeform in cavity two ports footpath.Being provided with like this can make the crooked when needed installation of power cable.
Preferably, the junction of said top and the bottom gold utensil main body is provided with elastomeric element, makes top and the bottom gold utensil main body bear the elastic force cushioning effect.
Further, preferred one or both in spring, rubber blanket, foam-rubber cushion of said elastomeric element.Also can be other parts that play the elastic force cushioning effect.
The beneficial effect of constraint power cable gold utensil is that this power cable gold utensil is applicable to the arc mounting bracket of modern power cable tunnel in the middle of the utility model three cores; Its installation, maintenance is convenient; And can do lane changes such as bending, lane change, changed course and install, snake laying and phase-splitting are laid, and improve the space service efficiency of packing density and power cable tunnel greatly.In addition, the power cable gold utensil of the utility model can be installed three power cables simultaneously, has saved installation cost.
