Description
Technical field
The utility model relates to engineering construction cable mounting technique field, particularly a kind of flexible fixing device of electric cable with large cross-section vertical run.
Background technology
The national clearly regulation that is fixed with to electric device installing engineering cable during 35kV and following cable vertical (or surpassing 45 degree inclinations) surface, should be established fixing position at upper and lower end and middle right quantity position.And cable fixedly the parts of usefulness should select: metal band, rope are moulded in band steel system anchor clamps, nylon cable tie, plating.At present the common mode of cable lifting is on need set up the building of electric cable with large cross-section, cable testing bridge to be set, and electric cable with large cross-section is fixed on this cable testing bridge through fixed part.Because the oversheath smoother of cable and lacking flexibility, the deadweight of cable increases the weight of with the increase in its cross section, and therefore the problem that exists of this vertical run mode is:
1, use the clamps cable: its size to the cable clamping force is different because of workmen's sensation, and clamping force is excessive to be prone to cause cable cover(ing) and cable insulation impaired, influences the useful life of cable.Clamping force is little, and fixed part can not weaken the supporting role to cable weight to the locking of cable reliable fixation;
2, with nylon cable tie, plating when moulding metal band or lanyard cable, its hold to the small bore cable can meet the demands basically, but for 95mm
2The hold of above electric cable with large cross-section does not all reach requirement, does not have to the fixing and locking of cable with to the supporting role of cable weight;
3, the power that cable receives deadweight, expands with heat and contract with cold, the influence of other mechanical forces such as electric power, wind-force produces all will act on the said fixing parts, make it produce loosening, damaged and forfeiture fixing and locking and to the supporting role of cable weight;
4, the position that is fixed of cable; Because of bearing the total weight of this cable overhang for a long time, be prone to make its core impaired with insulation, and the cable cover(ing) at this position and insulation; Also impaired because of the extruding that receives the whole gravity of this cable overhang, influence useful life of cable.Simultaneously cable expand with heat and contract with cold, when producing slippage under other mechanical force such as electric power, wind-force, the sheath of its fixed position is vulnerable to wearing and tearing.
Summary of the invention
The purpose of the utility model provides a kind of flexible fixing device that eliminates safe hidden trouble, prolongs the electric cable with large cross-section vertical run in cable useful life.
The purpose of the utility model realizes through following technical proposals:
The flexible fixing device of the electric cable with large cross-section vertical run of the utility model; Comprise the cable testing bridge, cable and the stationary fixture that are provided with the crane span structure stull; It is characterized in that in the crane span structure stull of said cable testing bridge, being provided with flexible fixing device; This flexible fixing device comprises the circular protective sleeve that clamp and semicircle outer card plate form in semicircle that the inwall and the outer surface of said cable be abutted against mutually, and the outer surface of this circular protective sleeve is abutted against with the U-shaped jig mutually, and the two ends of this U-shaped jig fix with described crane span structure stull through nut and are connected; Clamp and semicircle outer card plate constitute the endoporus of bell mouth shape in the described semicircle; Between this endoporus and said cable, be provided with two semicircle wedge shape liner plates, the outer wall of clamp is provided with connecting plate in the described semicircle, and the lower surface of this connecting plate is abutted against with the upper surface of said crane span structure stull mutually.
Gap between said two semicircle wedge shape liner plates is 10-15mm.
The material of described semicircle wedge shape liner plate is a rubber.
The characteristics of the flexible fixing device of the electric cable with large cross-section vertical run of the utility model are:
The circular protective sleeve that employing is formed by clamp in semicircle and semicircle outer card plate; Clamp and semicircle outer card plate constitute the bell mouth shape endoporus of circular protective sleeve in semicircle; Between this bell mouth shape endoporus and said cable, be provided with the structure of two semicircle wedge shape liner plates; When cable when deadweight or the effect of other external force are glided, cable will drive two semicircle wedge shape liner plates in circular protective sleeve to lower slider.Because the bell mouth shape endoporus is up big and down small; And the external diameter of two semicircle wedge shape liner plates also is up big and down small; Along with cable to lower slider, two semicircle wedge shape liner plates progressively increase the frictional force of bell mouth shape endoporus, when semicircle wedge shape liner plate to the frictional force of bell mouth shape endoporus during greater than the deadweight of cable or other external force; Cable will stop to lower slider, thereby reach the fixing and locking to cable.Simultaneously also avoid the impaired of cable cover(ing) and cable insulation, prolonged the useful life of cable.
The utility model is simple in structure, and is convenient for installation and maintenance, prolongs the useful life of cable, reduced operating cost.Avoided impaired, caused the generation of accidents such as electric shock, fire, power failure because of the insulation of cable.
