Lattice structure, lattice structure coupling body, work machine, and connector

A lattice structure which is mounted on a work machine, and is detachably coupled to a counterpart lattice structure adjacent to the lattice structure, the lattice structure comprising:

• a plurality of main pipes arranged at an interval in a radial direction;
• a plurality of inclined pipes extending so as to be inclined with respect to an axial direction of each of the plurality of main pipes, each of the plurality of inclined pipes coupling any two of the plurality of main pipes to each other;
• and
• a plurality of connectors detachably coupled to a plurality of counterpart connectors included in the counterpart lattice structure,
• wherein the plurality of connectors includes a predetermined connector to which an end portion of any one of the plurality of main pipes is connected, and to which an end portion of at least one of the plurality of inclined pipes is connected,
• the predetermined connector includes:
• a first connecting portion to which the inclined pipe extending in a first inclined direction among the plurality of inclined pipes is connected;
• and
• a second connecting portion to which the inclined pipe extending in a second inclined direction among the plurality of inclined pipes is connected,
• the predetermined connector has a pin insertion hole into which a coupling pin is inserted, and is configured such that the predetermined connector is connected to the counterpart connector by inserting the coupling pin into the pin insertion hole and a pin insertion hole formed in the counterpart connector which corresponds to the predetermined connector, and
• all of a center axis line of the main pipe connected to the predetermined connector, a center axis line of the inclined pipe connected to the first connecting portion, and a center axis line of an inclined pipe connected to the second connecting portion pass through at least one of a region surrounded by an inner peripheral surface which defines the pin insertion hole of the predetermined connector and a region surrounded by an inner peripheral surface which defines the pin insertion hole of the counterpart connector.

A connector

• used for a work machine and forming an end portion of a lattice structure which includes:
• a plurality of main pipes arranged at an interval in a radial direction;
• and a plurality of inclined pipes extending so as to be inclined with respect to an axial direction of each of the plurality of main pipes, each of the plurality of inclined pipes coupling any two of the plurality of main pipes to each other, the connector being detachably coupled to a counterpart connector included in a counterpart structure adjacent to the lattice structure, the connector comprising:
• a coupling portion for coupling the counterpart connector;
• a main pipe connecting portion for connecting an end portion of a predetermined main pipe among the plurality of main pipes;
• and
