Description
Technical field
The utility model relates to a kind of circuit breaker cradle that has the anchor bolt protective cap.
Background technology
At present, the circuit breaker mounting bracket has the integrative-structure of traditional armored concrete line bar and angle steel weldering system.The integrative-structure of angle steel weldering system is heavy, can't dismantle, be inconvenient to install, and the cost of transportation height, and easily leak out of doors and corrosion.Armored concrete line bar simple installation, detachable moving, use more flexible, but the set bolt of lower installation board and nut are exposed in the atmospheric environment throughout the year, be subjected to the influence of wind and weather and corrosive gas, corrosion phenomena takes place easily, it is fixing unreliable to cause, when perhaps needing to dismantle, because of corrosion is difficult for loosening.
The utility model content
The purpose of this utility model provides a kind of circuit breaker cradle that has the anchor bolt protective cap that can effectively prevent the bolt and nut corrosion.
For achieving the above object, the technical solution of the utility model is: a kind of circuit breaker cradle that has the anchor bolt protective cap, comprise concrete line bar, the bar-mat reinforcement periphery of the described concrete line bar naked leakage in upper end is electrically connected with the conducting metal circle, is electrically connected above the conducting metal circle and is provided with upper mounting plate; Be electrically connected with the earth connection that adapts with conducting metal circle and concrete line bar profile below the upper mounting plate, earth connection is electrically connected with the conducting metal circle, earth connection lower end ground connection; Concrete line bar lower end is provided with lower installation board, and lower installation board is installed on the seat of basis by bolt, screw connector, it is characterized in that: be arranged with protective cap on described bolt, the screw connector.
Bolt chamber and nut cavity that described protective cap adapts by the cap body, with screw bolt and nut constitute, and the cap body profile is the cylindrical boss that top is little, the bottom is big.
Described lower installation board is electrically connected with bar-mat reinforcement.
The screw thread that is complementary with bolt is arranged in the described bolt chamber.
Described protective cap is a plastic injection piece.
Described earth connection adopts Type of Welding to be connected with upper mounting plate and conducting metal circle.
Described earth connection is the ground connection band iron.
Advantage of the present utility model:
1, on bolt, screw connector, is arranged with protective cap; can prevent effectively that bolt, screw connector are subjected to the destruction of wind and weather and corrosive gas; avoid taking place corrosion; guarantee the reliability of connection; guarantee the support secure fixation; bolt, screw connector are dismantled easily, prolong connector useful life.
2, protective cap is plastic injection piece, and is simple in structure, with low cost.
3, earth connection adopts the ground connection band iron, and band iron and conducting metal circle contact area are big, and ampacity is big, and the intensity height, and long service life is with low cost.

Embodiment
A kind of circuit breaker cradle that has the anchor bolt protective cap as shown in Figure 1; it comprises columniform concrete line bar 1; the inside of concrete line bar 1 is provided with bar-mat reinforcement 11; the naked leakage in the upper end of bar-mat reinforcement 11 is in concrete line bar 1 outside; be provided with conducting metal circle 2 bar-mat reinforcement 11 peripheral electrical connections; be electrically connected above the conducting metal circle 2 and be provided with upper mounting plate 3, upper mounting plate 3 is used to install electric equipment.Lower end at concrete line bar 1 is provided with lower installation board 5, and lower installation board 5 is fixed on the basis seat 6 by bolt, screw connector 7 with bar-mat reinforcement 11 lower ends welding, lower installation board 5.For preventing that bolt, screw connector 7 corrosions from damaging, and is provided with protective cap 8 on bolt, screw connector 7.As Fig. 2, shown in Figure 3, bolt chamber 82 and nut cavity 83 that protective cap 8 adapts by cap body 81, with bolt, screw connector 7 constitute, and cap body 81 profiles are the cylindrical boss that top is little, the bottom is big.Protective cap 8 is a plastic injection piece, and the screw thread that has the bolt with bolt, screw connector 7 to be complementary in bolt chamber 82 is fixedly installed on bolt, the screw connector 7 to make things convenient for protective cap 8, and simple in structure, cost is low.Conducting metal circle 2 is formed by welded steel plate, and the material of upper mounting plate 3 is a steel plate.Below upper mounting plate 3, be electrically connected with earth connection 4, earth connection 4 extends downwards and the profile of conducting metal circle 2 and concrete line bar 1 adapts, be that earth connection 4 is welded on the surface of conducting metal circle 2, by being close on the surface of concrete line bar 1 the lower end ground connection of earth connection 4 after the bending.Described earth connection 4 is the ground connection band iron, can effectively increase the contact area with conducting metal circle 2, increases the ampacity of earth connection 4.
In the present embodiment, Type of Welding is all adopted in described electrical connection, has both guaranteed good electrical conductivity, improves bonding strength again.
