Be convenient to a method of operating for loading and unloading type drilling rod in constructing tunnel process, comprise:
When two drilling rods connect, directly insert in the square opening of a drill rod thread termination by the square termination of a wherein drilling rod, flexible nut stretches out and screws with the threaded end of another root drilling rod, makes compact siro spinning technology between drilling rod;
When two drilling rods are separated, put into by spanner on a pair even surface of flexible nut, the nut that will stretch screws out, and is separated drilling rod.
The invention has the beneficial effects as follows:
Present invention decreases in drilling process the time adding bar extension bar, one is provided to add bar, extension bar method flexibly, efficiently, be used for the drawback that rig reverses, spanner unloads bar brought for the original drilling rod mode of spinning, make drilling rod add bar extension bar mode and become card edge type by rotary joint style before, improve the operating efficiency adding bar extension bar, ensure that the agility of probing work and normal duration.
Jackrod structure of the present invention is simple, and preferable operability, is convenient for carrying; Bar, extension bar can be added fast, require great effort less, easy to loading and unloading; Driving force between enough rod member can be provided, ensure to creep into without barrier in drilling rod rotation process, and without the need to the restarting mating reaction of rig.

Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:
Be convenient to loading and unloading type drilling rod in a kind of constructing tunnel process, comprise: rod member main body 7, be provided with square termination 1 in one end of rod member main body 7, be provided with flexible nut 2 in square termination 1 with the link position place of rod member main body 7; The other end of rod member main body 7 is provided with threaded end 5, and threaded end 5 inside has the square opening 6 corresponding with square termination 1;
Square termination 1 is a cuboid column cap, square opening 6 in the threaded end 5 of its size and another root drilling rod is in the same size, and in drilling process, rig orders about drilling rod and rotates and creep into, square termination 1 and square opening 6 increase the moment of torsion of drilling rod junction, play the intermal force between drilling rod.
Square termination 1 is drilling rod one end, directly inserts in the square opening 6 of its threaded end 5 when connecting another root drilling rod; Flexible nut 2 stretches out and screws with another root drill rod thread termination 5; Threaded end is the screw structural that diameter is larger, and threaded end 5 is consistent with flexible nut 2 aperture, and its inside is a square opening 6, insert in order to square termination 1, then screw flexible nut 2, make compact siro spinning technology between drilling rod, what complete drilling rod adds bar operation, and Fast Persistence creeps into.
