At the upper end of 01, a hanger 403 is installed via a bearing 423 and a flat bearing 424. Support leg 60 on hanger 403
1, 601 are pin-connected. The main pillar 401 is formed of a pipe except for the upper and lower ends and the seat 401a.

In such a configuration, when the driving device 405 is rotated, the main column 401 rotates and the boom 301 turns. Sheaves 407 and 408 also turn. For this reason, the rope 305 between the sheave 407 and the sheave 406 fixed to the gantry 402 is twisted by the rotation angle of the main column 401, but the rotation angle of the main column 401 does not exceed 360 degrees, so there is no problem. .

By combining the turning of the main column 401 and the tilting of the chute 501 in the front-back direction (sea-land direction),
Bulks carried in from the conveyor 101 can be almost uniformly stacked in the opening 902 of the ship 901.

The drum 603 includes connecting members 602, 602,
Since it is mounted on the drum 605, foundation work for the drum 603 can be omitted.

1, 422, which support the turntable 201. The rotation center of the turntable 201 and the rotation center of the main column 401 are the same. The outer periphery of the turntable 201 has a circular shape, and three or more rollers 420 that are in contact with the lower end of the outer surface from the outside are attached to the seat 421a of the roller 421. The rotation axis of the roller 420 is vertical.

In order to rotate the turntable 201,
On the outer periphery of the turntable 201, there is provided a gear 210 (which may be made of chain). The pinion 431 of the electric motor 430 meshes with the gear 210.

The lower end of the seat 433 on which the motor 430 is installed is attached to a seat 401b on the outer surface of the seat 401a via a pin 434. The axis of the pin 434 is vertical. For this reason, the seat 433 can rotate in the horizontal direction. The upper end of the seat 433 and the upper end of the seat 401c raised from the seat 401a are connected with bolts 435. Upper end of seat 433 and seat 4
A compression spring 436 is disposed between the compression spring 436 and the compression spring 436. Seat 4
The distance between 33 and seat 401c changes depending on the load applied to compression spring 436. A roller 439 that is in contact with the outer periphery of the turntable 201 is provided on a seat 437 provided on the seat 433. With the pinion 431 at the center, there is a compression spring 436 on one side and a roller 439 on the other side.

In this configuration, the roller 439 is pressed against the outer peripheral surface of the turntable 201 by the compression spring 436. Therefore, when the rotation axis of the turntable 201 changes, the position of the roller 439 changes, and the position of the pinion 431 changes accordingly. Therefore, the position of the pinion 431 with respect to the gear 210 does not substantially change. That is, the engagement between both does not change. Therefore, the turntable 201 can be favorably rotated. That is, the pinion 431 does not bite or move away from the gear 210. The compression spring 436 is a device for pressing the roller 439 against the turntable 201.

If a concave guide is provided in a ring shape on the turntable 201 and the roller 439 is arranged in the concave portion of the guide, a compression spring can be eliminated.

Reference numeral 206 denotes a ring-shaped inner guide,
It is installed on the main pillar 401. Reference numeral 207 denotes a ring-shaped outer guide, which is supported from the outer peripheral end of the seat 401a.
The guides 206 and 207 prevent the falling objects from falling.

The motor 430, the drums 507, 50
8. The power source of the conveyor 302 can be passed through the main pillar 401 like a rope 305.

As described above, the conveyor 302 is
Since it is supported by the member consisting of the support legs 1 and the support legs 601, the configuration can be simplified, and the weight and cost can be reduced. In addition, since the conveyor 302 is supplied via the turntable 201, even if the direction of the conveyor changes, loose materials can be easily supplied. Since the turntable 201 is provided concentrically with the main pillar 401, the position from the conveyor 101 does not change even if the direction of the conveyor 302 is changed.
The turntable 201 can be made smaller. Without providing the turntable 201, the scraper can be rotated to transport the loose objects to the chute 204.

FIG. 15 shows a configuration in which winding drums 507 and 508 for tilting a chute 501 are mounted on a seat 602602. Rope 50 fixed to the tip of chute 501
3 is fixed to the drum 507 via the sheave 505 of the boom 301, the sheaves 408 and 407 of the main column 401, and the sheave 406 of the gantry 402 in this order. Similarly rope 50
4 is the sheaves 506 and 505 of the boom 301 and the main pillar 40
1 sheaves 408 and 407, sheave 406 of gantry 402
, And is fixed to the drum 508. Sheave 5
05, and three sheaves 408, 407, 406 each.

Since the rope 504 passes through the sheave 505, the inclination of the chute 501 and the operation of the drum 508 can be facilitated as compared with the case where the rope 504 does not pass.

The above is a fixed type. However, if the gantry 402 and the base seats 604 and 604 are supported by respective traveling bodies, they can be run. It can also be used for loading on the ground, not on ships.
