FIG. 1 is a side view of a main part in which a television camera 30 is attached to a tip end portion of a crane boom 10 in a tower crane by the attachment device according to the present invention. FIG. 2 is a plan view thereof. First, the fixed base 40 attached to the tip of the crane boom 10 was formed of a tubular material obtained by cutting a steel pipe material having a rectangular cross section. Then, as shown in FIG. 1, it was mounted on the angle member 41 fixed to the tip of the crane boom 10. The reason for mounting via the angle member 41 is that the axis of the guide hole 40a formed by the fixed base 40 is held substantially horizontal. Next, the arm 42 having the guide roller 43 at the tip is installed on the upper surface of the fixed base 40 in an obliquely upward direction. As shown in the plan view of FIG. 2, the fixed base 40 for the tip of the crane boom 10 is attached to one side of the crane boom 10 so that the position of the TV camera 30 is directly above the load. did.

Next, the mounting base 44 having a vertical opening 45 at the tip thereof is a tube made of a steel pipe or the like having a rectangular cross section so that it can be slidably held in the guide hole 40 a formed by the fixed base 40. Made up of a body. That is, the mounting base 44 made of this cylindrical body is slidably inserted into the guide hole 40a of the fixed base 40 and held. The opening 45 was a rectangular opening 45 as shown in FIG.

In the embodiment, the front end side of the mounting base 44 is formed by cutting off the lower surface on the left side as shown in FIG. 1 to reduce the weight as a whole. Further, a detachment prevention plate 46 is integrally attached to the base end portion as shown in FIGS. 1 and 2 so as to prevent the attachment base 44 itself from falling out of the guide hole 40a of the fixed base 40. .

FIG. 3 is a perspective view for explaining the structure of the hanging member 47 of the television camera 30 attached to the opening 45 of the mounting base 44 and a procedure for inserting the mounting base 44 into the opening 45. The hanging metal fitting 47 was configured as a hanging metal fitting 47 having a T-shaped side surface as shown in the drawing. In the embodiment, the horizontal member 47a obtained by cutting the C-shaped channel material and the vertical member 47b which is also made of the C-shaped channel material are integrally connected to each other, and the side surface has a substantially T-shape as shown in the drawing. The hanging metal fitting 47 is used. At that time, the width ha of the horizontal member 47a of the hanging fixture 47 is set to be smaller than the width Ha of the opening 45 in the mounting base 44, and the length wb is set to be shorter than the length Wb of the opening 45 in the mounting base 44. . That is, when the horizontal member 47a corresponding to the head of the hanging metal fitting 47 is inserted from the lower side of the opening 45 in the mounting base 44 and then the hanging metal fitting 47 itself is rotated 90 degrees about the vertical axis, the horizontal member 47a is moved to the above-mentioned position. The structure is such that it is locked in the opening 45 of the mounting base 44 and can be suspended without falling off.

The television camera 30 is designed to be integrally grasped and fixed to the vertical member 47b of the hanging metal fitting 47 in advance by using a mounting screw or the like, as shown by an imaginary line. Reference numeral 48 is a connecting ear piece for connecting a hanging wire or a hanging rope 49 integrally attached to the horizontal member 47a, that is, to the head of the hanging metal fitting 47.

FIG. 4 shows the operation of inserting the horizontal member 47 a, which corresponds to the head of the hanging metal fitting 47, into the opening 45 of the mounting base 44 from below and half-rotating it to lock it in the opening 45. It is the expansion top view shown diagrammatically. Incidentally, 50 is a lock nut for fixing the horizontal member 47 a of the hanging metal fitting 47 to the mounting base 44.

FIG. 5 is a side view of the TV camera mounting portion for explaining a procedure of removing the TV camera 30 from the crane boom 10 side and lowering it to the ground because a trouble occurs in the TV camera 30. First, as shown in the figure, the mounting base 44 supported by the fixed base 40 installed at the tip of the crane boom 10 is pulled toward the crane boom 10 side, that is, in the direction of the arrow. After being pulled, the mounting base 44 is temporarily locked to the fixed base 40 side using a screw or the like.

Then, as shown in the plan view of FIG. 6, the guide roller 43 of the arm 42 that projects obliquely upward from the fixed base 40 side comes to a position directly above the hanging metal fitting 47 that suspends the television camera 30. Therefore, the hanging wire or the hanging rope 49 is connected to the connecting ear piece 48 provided on the head of the hanging metal fitting 47 via the guide roller 43. The suspension rope 49 is connected to a winch attached to the crane itself.

When the connection of the suspension rope 49 to the suspension fitting 47 is completed, the television camera 30 integrated with the suspension fitting 47 is rotated half a turn around the vertical axis. Then, the hanging metal fitting 47 is disengaged from the opening 45 in the mounting base 44. That is, the TV camera 30 is separated from the crane boom 10 side together with the hanging metal fitting 47. Therefore, as shown in FIG. 5, the suspension rope 49 is loosened and the television camera 30 is lowered to the ground, and appropriate repairs and adjustments are performed. It should be noted that, when the processing such as repair and adjustment is finished, the current state can be easily restored by hoisting using the hoisting rope 49.
