Description
Technical Field
The present utility model relates to a rotational force applying mechanism for applying a rotational force to a tool attached to a remote rotational operation tool, and more particularly, to a rotational force applying mechanism configured to be attached to a rotation conversion mechanism provided on an operation portion of an operation rod used for, for example, wiring of overhead wires by an indirect firing line construction method, for rotating a drive shaft.

Problems to be solved by the utility model
However, for example, in a construction method for a high-voltage wire, a high torque is required for tightening, and therefore, a high torque electric drill is required, but if the rotation speed is too high, the operation of a rotation tool located at a high position is in many cases laborious.
Since the (trigger type) electric drill (driving device) of patent document 1 is directly connected to the tool operating rod, when an end effector (a member to which a rotary tool attached to the front end portion of the tool operating rod acts, for example, a grip portion of a wire gripping tool, a wire cutting tool, a cutting blade of a peeling tool, or the like) is brought into contact with an object to be operated (for example, a wire), a large reaction force (torque) acts on an output shaft of the driving device from an output shaft coupling portion of the tool operating rod, and a load on an operator gripping a grip portion of the driving device is large.
The electric drill of patent document 2 is axially coupled to a rotary shaft incorporated in a remote insulating operation rod, and the number of rotations of the electric drill is not changed according to on/off of the electric drill.
With a general trigger type electric drill, the number of rotations varies according to the degree of gripping of the trigger, and the more tightly the grip is, the more the number of rotations increases. In the case of using such a (trigger type) electric drill operation, it is difficult to perform the operation while adjusting the grip level of the trigger at the operation site, and the operation is a normal operation state in a state where the grip is tight, that is, in a state where the rotation number is the maximum. Therefore, it is desirable to be able to obtain a required torque for a rotary tool mounted to the front end of a tool operating rod.
When an end effector attached to the distal end portion of the tool operating rod (a member to which a tool attached to the distal end portion acts, for example, a grip portion of a wire gripping tool, a wire cutting tool, a cutting blade of a peeling tool, or the like) is brought into contact with an object to be operated (for example, a wire), a large reaction force (torque) is applied from an output shaft coupling portion of the tool operating rod to an output shaft of the driving device, and the coupling tool and the electric drill are also subjected to the large reaction force, which hinders safety of an operator.
Therefore, it is desirable to ensure safety of the operator even when a reaction force (torque) equal to or greater than a predetermined reaction force (torque) acts.
The present utility model has been made in view of the above circumstances, and a main object of the present utility model is to provide a rotational force applying mechanism that applies a rotational force to a drive shaft of a remote rotational operation tool, so that the rotational speed of a rotational shaft that rotates a rotary tool is not excessively high and the operation is not laborious, and the burden on an operator due to a large reaction force can be reduced.

When the operator rotates the drive device output shaft 302 of the drive device 300 while holding the handle 306 of the drive device 300, if the end effector 504 of the rotary tool 500 attached to the tip of the operation rod 12 is in contact with an object (for example, an electric wire), a large reaction force (large torque) acts on the drive device output shaft 302 of the drive device 300 from the rotation conversion mechanism 24 or the like constituting the rotation force transmission mechanism 20 of the operation rod 12.
However, the mounting member 330 prevents the entire drive device 300 from rotating about the drive device output shaft 302 due to the reaction force that the drive device 300 receives from the operation rod 12.
