A kind of cable protecting device
The present invention relates to power domain, be specifically related to a kind of cable protection facility.
At present, in order to protect power cable on the electric power electric pole that is laid in not by outside destroy, the way that adopts cable to wear seamless steel pipe.Cable terminal hang connect before, earlier with cable through in the seamless steel pipe.Because cable and seamless steel pipe are all heavier, hang when connecing cable in installation, lift with steel pipe owing to cable on the one hand; Increased lifting weight and difficulty, on the other hand, when banded cable lifting steel pipes; The steel pipe mouth of pipe destroys cable sheath easily; Cause cable failure, reduce cable useful life, have construction safety hidden danger.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of installing/dismounting of being convenient to is provided, the cable on the electric pole that conveniently is laid in is changed, is keeped in repair or migration, has the cable protecting device of anti-theft feature simultaneously.
The present invention mainly is made up of cable protection pipe and clip; Solving the technical scheme that its technical problem adopts is that cable protection pipe adopts the split fastening structure; Cable protection pipe is combined by two semicircle pipe fittings; Vertical outer ledge of semicircle pipe fitting is provided with some ear seats, and the ear seat is provided with the keyhole that is used for construction bolt; Clip one end is provided with the line bar clip that connects the concrete bar, and the other end is provided with the protection tube clip of stube cable protection tube, and the protection tube clip is one-sided semi-circular structure, and the protection tube ear seat keyhole on the keyhole of protection tube clip and cable protection pipe top is supporting; At the cable protection pipe upper orifice cable protection plug is set; The cable protection plug is the semicircular body of two fastenings; Cable protection plug internal diameter is slightly larger than cable size, and through being equal to the cable protection bore, cable protection plug top is provided with the cock cap that is equal to the cable protection external diameter of pipe outward.
The invention has the beneficial effects as follows sleeve pipe operation loaded down with trivial details when having avoided cable to change and install; Said apparatus structure is simple, and easy installation and removal has improved operating efficiency and construction safety coefficient; A large amount of manpower and materials have been practiced thrift; Avoid the artificial damage of cable, solved mouth of pipe toy and pierced the problem of damaging cable, can be widely used in the cable protection in the power domain.
Description of drawings
Below in conjunction with accompanying drawing and instance the present invention is further specified.
Fig. 1 is the structural representation of cable protecting device of the present invention.
Wherein 1 cable protection pipe, 2 concrete bar clips, 3 bolts, 4 protection tube ear seats, 5 keyholes, 6 protection tube clips, 7 cable protection plugs, 8 cock caps.
As shown in the figure; Cable protection pipe 1 adopts the split fastening structure, and cable protection pipe 1 is combined by two semicircle pipe fittings, and vertical outer ledge of semicircle pipe fitting is provided with some protection tube ear seats 4, and ear seat 4 is provided with the keyhole 5 that is used for construction bolt 3; Clip one end is provided with the line bar clip 2 of concrete bar, and the other end is provided with the protection tube clip 6 of cable protection pipe 1, and protection tube clip 6 is one-sided semi-circular structure, and the keyhole 5 of protection tube clip 6 is supporting with protection tube ear seat 4 keyholes on cable protection pipe 1 top; At cable protection pipe 1 upper orifice cable protection plug 7 is set; Cable protection plug 7 is the semicircular body of two fastenings; Cable protection plug 7 internal diameters are slightly larger than cable size, and through being equal to cable protection pipe 1 internal diameter, cable protection plug 7 tops are provided with the cock cap 8 that is equal to the cable protection external diameter of pipe outward.
During use; Can earlier the power cable lifting be applied on the concrete bar; Encase with the cable of cable protecting device with position about the face of land then, use bolt that cable protecting device locking is closed, the protection tube clip is attached on the protection tube ear seat of cable protection pipe one side; Bolt tightening, the clip other end and electric pole are fixed together.Such installation process is time saving and energy saving, can not damage cable sheath.When the cable in the cable protecting device needs to change, keeps in repair or moves, only need open the fixture of fixed card and cable protection pipe, two pipe fittings of cable protection pipe are separated, can take out cable, realize replacing, maintenance or the migration of cable.
