Abstract
The utility model discloses an earth connection linking board raiser, which comprises an arc-shaped lock card, an opening of the lock card is matched with the diameter of an electrical pole, one end of the lock card is provided with a tension bar holdfast, and a tension bar hole is arranged on the holdfast, one end of the tension bar is provided with screw threads which penetrates the tension bar hole and matches with a female screw, and the other end of the tension bar is provided with a drag hook. The utility model is fastened on the electrical pole, the tension bar is adjusted by the female screw, and the drag hook is led to hook on the lower portion of an earth connection linking board, and the tension bar is upwards moved by fastening the female screw, and an earth connection linking board hole is led to aim at a pole tower hole, and securing can be achieved. The utility model has the advantages of compact and simple structure, which can conveniently fix the earth connection linking board on the electrical pole, can improve operational efficiency, and can shorten operating time.
Description
Technical field:
The utility model relates to a kind of electric power facility maintenance tool, particularly relates to a kind of ground connection connecting plate lifter.
Background technology:
In the electric power facility, transmission line is the passage of power supply, is made up of concrete bar, iron tower, lead, insulator etc.; In order to guarantee transmit electricity safety and lightning protection needs, each basic bar, tower are equipped with earthing device, this device comprises and is embedded in underground earth polar and coupled ground connection connecting plate, connecting plate is provided with connecting hole, on the shaft tower body of the tower, also be provided with a hole accordingly, with bolt the ground connection connecting plate be fixed on the shaft tower body of the tower usually, when the staff carries out earth resistance and earth work operation, need the ground connection connecting plate is unloaded from shaft tower, again the ground connection connecting plate is returned on the shaft tower after testing.Because fault sag, ground wire is sunk, make dismounting and inconvenience is installed, its reason is that earth connection and connecting plate sink, and makes the dislocation of connecting plate hole and shaft tower hole, and the strength that the operating personnel need cost a lot of money just can be finished, increased task difficulty, prolonged the activity duration, sometimes even can't finish, made the operating personnel feel very inconvenience.
Summary of the invention:
The utility model is at the deficiencies in the prior art, a kind of ground connection connecting plate lifter is provided, technical problem to be solved is can be quick, easily the ground connection connecting plate that sinks is raised up, connecting plate hole and shaft tower hole are aligned, convenient fixing, improve operating efficiency, shorten the activity duration, technical solution adopted in the utility model is as follows: the utility model comprises the arc pintle hook lock, and the opening of pintle hook lock and the external diameter of electric pole are complementary, and an end of pintle hook lock is provided with rob support, establish tie rod hole on the support, one end of pull bar is established screw thread, passes tie rod hole and cooperates with nut, and the other end of pull bar is established drag hook.
Using method of the present utility model is as follows: at first according to the position of ground connection connecting plate on the electric pole, determine suitable height, to this novel being stuck on the electric pole by pintle hook lock, adjust pull bar by nut then, make drag hook be hooked in the below of ground connection connecting plate, last clamp nut, adjustment will move on the pull bar, hole on the ground connection connecting plate and the hole on the electric pole are aligned, can fix.
Compared with prior art, the utility model is rational in infrastructure, simple, can easily the ground connection connecting plate be fixed on the electric pole, improves operating efficiency, shortens the activity duration.
