Kind Code:
A
Abstract:
To provide a traction gear capable of reducing a load applied on a motor shaft of a motor.SOLUTION: A traction gear 21 comprises: a turning arm 30 connected so as to be turnable about a turning shaft in a vertical direction orthogonal to the advancing direction of an unmanned carrier body 20; and a lifting arm 31 moved in the vertical direction with respect to the turning arm 30. The lifting arm 31 has a hook 32 connected to a traction object, and a cam follower 34. An end surface cam 33 is installed in the turning arm 30 so as to be rotatable about a cam rotary shaft 67 in the vertical direction. The end surface cam 33 has a cam surface 68 annularly formed about the cam rotary shaft 67 to support the cam follower 34. A motor 35 for rotating the end surface cam 33 is installed in the turning arm 30. By lifting the lifting arm 31 via the cam follower 34 through the rotation of the end surface cam 33, the position of the hook 32 is changed to a position for connection to the traction object and a position for releasing the traction object.SELECTED DRAWING: Figure 4
