A kind of essential managing security tools and instruments, be most important Work tool in transmission line of electricity interruption maintenance operation, even more protection inspection
One of important safety curtain for repairing personnel, is the lifeline of electrical employee.Before carrying out line outage service work, it is necessary first to
Each circuit breaker, disconnecting switch and the fuse for needing to operate on open-circuit line, it is ensured that each hold of dead line has obvious break
It prescribes.Then electrical verification is carried out to required maintenance route again, after the clear no-voltage of experience, installing ground line immediately, it is ensured that place of working
Section both ends are all within ground wire protection scope.
The work of high-tension line interruption maintenance carries out usually on steel tower, and dedicated ground connection handle is needed to be hung on ground line
On steel tower, to achieve the purpose that ground short circuit.The fixture of work on hand ground connection end miniature lever uses screw-rod structure, leads to
The bolt with range-adjustable in fixture is crossed, handle is fixed on angle steel.Manual rotation's bolt multi-turn, ability are needed in operating process
Handle is clamped on steel tower corner iron, bothersome laborious, working efficiency is lower.Also, ground connection handle is fixed on the mistake on angle steel
Cheng Zhong needs both hands while being operated, and holds on operating stick on the other hand, and another hand rolling clamp is also wanted in high aerial work
Moment pays attention to keeping one's balance, work difficulty as one can imagine.It cannot free hand to during stationary fixture, to be ready to answer
To emergency event.In addition, being twisted due to pure with hand, after fixed, the clamping force for being grounded handle is smaller, refills after cleat angle
If ground connection handle is easy to happen loose or dislocation when conductor wire end, leads to the induced electricity of alive circuit generation around, causes personal injury,
There are security risks.
Summary of the invention
The utility model in order to overcome the shortcomings of the above technology, provide it is a kind of it is safe and efficient, easily realize power transmission line
The ratchet-type work of road service work is connected wires with ground connection handle.
The utility model overcomes the technical solution used by its technical problem to be:
A kind of work of ratchet-type is connected wires with ground connection handle, comprising:
Handle, the upper end are provided with lower fixture;
Upper fixture is hingedly installed on handle upper end by pin shaft I, U-lag is provided in the upper fixture, is set in upper fixture
It is equipped with ratchet;
Ground wire fixing device is set in upper fixture, is used for dead earth line;
Pawl is hingedly installed on handle by pin shaft II;And
Clamp arm spring, one clamp arm are connected with pawl, another clamp arm is connected with handle, the bullet of clamp arm spring
Power drive pawl is inserted into the spine slot of ratchet.
Preferably, above-mentioned ground wire fixing device includes several screw rods being set in upper fixture and is combined on screw rod
Nut, ground line is pressed in upper fixture by nut.
For the ease of unlock, above-mentioned handle is tube-shaped structure, is vertically arranged with connecting rod in inner hole, the connecting rod it is upper
End is connected with pawl, and handle, at its lower end is provided with handle, and the handle is connected with the lower end of connecting rod.
The beneficial effects of the utility model are: angle steel is caught in by the required fixed angle steel of U-lag alignment of upper fixture
In U-lag, continuous rotational handle, makes pawl constantly beat along ratchet later, until upper fixture and lower fixture are constantly clamped U-shaped
Angle steel in slot is fixedly clamped.Under the elastic force of clamp arm spring in the spine slot of pawl insertion ratchet, it can prevent from rotating backward, adopt
With ratchet-type structure, operating process is time saving and energy saving, can satisfy the needs of one-handed performance, guarantees not loosen after clamp, take off
It falls, prevents the generation of induced electricity casualty accident, and long-time service work (> 2 hours) can still guarantee securely and reliably.Effectively
The fixture for solving work on hand ground connection end miniature lever needs multi-turn rotation using screw-rod structure, operation, and clamping force it is small,
It refills to be easy to happen when setting conductor wire end after cleat angle and fall off, cause induced electricity the problems such as to be hurted sb.'s feelings, not only increase inspection
The operational security of personnel is repaired, and working efficiency is improved significantly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
In figure, lower 3. pin shaft of fixture, I 4. 7. nut of upper fixture 5.U shape 6. screw rod of slot, 8. pin shaft II of 1. handles 2.
9. 12. handle of pawl 10. ratchet, 11. clamp arm spring, 13. connecting rod.
Specific embodiment
1 pair of the utility model is described further with reference to the accompanying drawing.
A kind of work of ratchet-type is connected wires with ground connection handle, comprising: handle 1, the upper end are provided with lower fixture 2;Upper fixture
4,1 upper end of handle is hingedly installed on by pin shaft I 3, U-lag 5 is provided in upper fixture 4, ratchet 10 is provided in upper fixture 4;
