Transmission line shaft tower bolt-up belongs to the daily maintenance work, can directly use the spanner to the bolt on the body of the tower to fasten, but to drainage line yoke plate, suspension clamp and be close the shaft tower bolt of electrified wire, can only combine the power failure plan to inspect, fasten, and the circuit power failure number of times is few, the cycle length, hardly in time satisfies bolt-up defect processing demand. The drainage wire yoke plate and the suspension clamp are loosened and fall off by sudden bolts, serious accidents such as falling of a conducting wire and toppling of a tower can be caused seriously, the fastening and the supplement can be carried out only by adopting a live working mode, the technical requirement on the live working is high, the labor intensity is high, and the maintenance personnel can work on the tower for a long time, so that the potential safety risk hazard exists.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a multi-angle bolt fastening wrench for a ground potential.
The technical scheme provided by the utility model is as follows: a ground potential multi-angle bolt-tightening wrench, comprising: the device comprises an insulating rod, a spring, a universal joint and a torque wrench;
wherein, the insulator spindle links to each other with torque wrench, the insulator spindle adopts the pivot to be connected with torque wrench's junction, form lever structure, universal joint cooperation torque wrench and insulator spindle, can make the spanner adapt to each angle bolt-up operation, in use, the certain angle of orientation deflection to bolt-up exerts force, the pivot position of spanner will fold certain angle after the effect of power that receives this moment, and then drive torque wrench and rotate, after the power of exerting force in the hand was removed, because the effect of spring, the folding angle of pivot is got back to original state rapidly, this operation is carried out repeatedly, until bolt-up.
Preferably, the lower part of the torque wrench is provided with a movable joint, the bolt is fastened through the insulating rod matched with the torque wrench, and the wrench head can be detached and replaced according to different bolt models.
Further preferably, the torque wrench is provided with a ratchet wheel, and the operation can be completed without transferring the insulating rod for multiple times in the operation process.
Further preferably, the torque wrench joint adopts detachable construction, to the bolt of different specifications, can change the torque wrench of corresponding specification.
Preferably, the spring is a rigid spring, and the rigid spring can automatically return to an original state after the angle of the universal joint is changed.
The utility model has convenient operation, safety and reliability, and provides a ground potential multi-angle bolt fastening wrench, which changes the direction unicity of the original wrench by additionally arranging a universal joint between an insulating rod and a torque wrench, so that the wrench can be suitable for various angles, and can automatically restore the position of the universal joint by additionally arranging a strong spring sleeve outside the universal joint.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1 to 2, the present embodiment provides a ground potential multi-angle bolt fastening wrench, including: the device comprises an insulating rod 1, a spring 2, a universal joint 3 and a torque wrench 4;
wherein, insulator spindle 1 links to each other with torque wrench 4, insulator spindle 1 adopts the pivot to be connected with torque wrench 4's junction, form lever structure, universal joint 3 cooperation torque wrench 4 and insulator spindle 1, can make the spanner adapt to each angle bolt fastening operation, in use, certain angle of the orientation deflection that fastens to the bolt exerts force, the pivot position of spanner this moment will fold certain angle after the effect of received force, and then drive torque wrench 4 and rotate, after the power of exerting force in the hand is removed, because spring 2's effect, the folding angle of pivot is got back to original state rapidly, this operation is carried out repeatedly, until bolt fastening.
Preferably, the lower part of the torque wrench 4 is provided with a movable joint, the bolt is fastened by matching the insulating rod 1 with the torque wrench 4, and the wrench head can be detached and replaced according to different bolt models.
Preferably, a ratchet wheel is arranged in the torque wrench 4, so that the operation can be completed without transferring the insulating rod 1 for multiple times in the operation process, the existence of the ratchet wheel ensures that the wrench does not rotate screws when acting in the opposite direction, and the bolts on the overhead line can be fastened at the ground potential in a long distance by continuously repeating the action.
