Description

[Detailed Description of the Invention] This invention relates to a telescope device suitable for use when loading bulk materials into a ship's hold.

Generally, in order to efficiently load bulk materials into a ship's hold, a telescope device consisting of a telescopic cylinder is suspended from the tip of the boom, and the bulk materials that have been conveyed to the tip of the boom by a conveyor are transported to the depths of the ship's hold. The material is dropped through each cylinder of a telescope device whose height is adjusted to the same height as the material, and then loaded onto the ship.

However, with this device, bulk materials could only be loaded directly below the telescope device, which was inconvenient for uniformly loading the entire cargo hold. For this reason, there are some systems that attach a trimmer device to the bottom of the telescope device and use centrifugal force to scatter loose materials, but this method has the disadvantage that bulk materials cannot be loaded directly below the loading device. It was hot.

This invention was proposed in view of the above, and its purpose is to provide an efficient telescopic system that can load bulk materials into a ship's hold over a wide area immediately below and around the loading device using a simple device. This is an attempt to propose a ute device. This invention will be described below with reference to embodiments shown in the drawings.

In Figures 1 to 5, 1 indicates pin 2 on the boom (not shown).
and a support bracket suspended by the cylinder 3, 4,
5, 6, 7, 8 are cylindrical chute bodies, the uppermost chute body 4 is attached to the support fitting 1, and the chute bodies 5, 6, 7, 8 is fitted telescopically. And each shoot body 4, 5,
6 and 7 have ribs 4A, 5A, 6A, and 7A protruding in the longitudinal direction at four locations on the outer periphery, and the upper and
At the lower end, an engaging portion for preventing detachment and engaging portions 4B, 5B, 6B, 7B, and 8B for the ribs are formed.

Reference numeral 9 denotes a sheave that is wound and supported by a wire lobe 10, and the chute body 4,
5, 6, 7, and 8 can be expanded and contracted in the vertical direction. The lowermost chute body 8 is composed of an elevating ring 11 that is fixed to the elevating ring 7 and fitted into the elevating ring 7, and a cylindrical chute body 8' that is rotatably supported by the elevating ring 11. The chute body 8 is turned by the motor 12 which is rotated.

Reference numeral 13 denotes a bucket chute having a U-shaped cross section and having an inclined chute surface 14 formed thereon, and the chute 13 is rotatably supported by a pin 15 on the outer wall of the chute body 8 on the opposite side of the inclined chute surface 14. The dimension between the pin 15 and the upper and lower ends of the inclined chute surface 14 is larger than the dimension between the pin 15 and the lower end of the cylindrical chute 8' on the opposite side. Reference numeral 16 denotes a motor cylinder, and the piston rod end of the cylinder 16 is pinned 18 to a support metal fitting 17 protruding from the chute body 8, and the cylinder portion is swingably supported by a pin 20 on the frame 19 of the bucket chute 13. There is.

Reference numeral 21 denotes a bracket protruding from the outer wall of the chute body 8. A buffer material 22 is attached to the bracket 21, and the frame 19 of the bucket chute 13 is placed on the buffer material 22. ing. Reference numeral 23 denotes a cable that supplies driving power to the motor cylinder 16, which is wound inside a collar 24 formed on the outer peripheral wall of the chute body 8, and is connected to a sheave 25 attached to the lifting ring 11, and an automatic cable winding drum 26. It is designed so that it can be wound and wound up.

27 is a limit switch for detecting the stored state of the bucket chute 15; 28 is a bulk material conveyor provided on a boom (not shown); 29 is a hopper;
0 is the ship's hold.

The present invention is constructed as described above, and its operation will be described next. First, put this telescopic chute device into the hold 30, operate the winding device on the boom to set each chute body to a predetermined length, and move the bucket chute 13 to the lowermost chute body 8.
Store it on the side. The bulk materials fed by the transport conveyor 28 are dropped through the hopper 29, passed through the respective chute bodies 4, 5, 6, 7, and 8, and loaded onto the ship.

After a predetermined amount has been loaded, the motor cylinder 16 is operated to bring the bucket chute 13 toward the drop-in port of the chute body 8. The dropped loose materials fall onto the inclined chute surface 14 of the bucket chute 13, but since the chute surface 14 has a predetermined angle of inclination, the loose materials are guided by the chute surface 14 and move away from the dropping point. It is released to a remote location (side point) and loaded onto a ship.

During this side point loading operation, the bucket chute 13 receives an impact force from the bulk materials, but the bucket chute 1
3 is placed on the cushioning material 22, so that the motor cylinder 16 is not damaged. In addition, the chute body 8 to which the bucket chute 13 is attached receives a side shipping reaction force, but this reaction force is transmitted by the ribs formed on each chute body, and is transmitted to the uppermost chute body 4. Since it is blocked by the pivot pin 2 and the cylinder 3, side point shipping is ensured. Then, when the chute body 8 is rotated by the motor 12, the bulk materials are loaded into the ship's hold in a predetermined area with a radius around the center of rotation of the chute body 8.

Next, operate the motor cylinder 16 and pull down the cylinder part, and the cylinder part and pin 20
The pivot joint with the bucket is pulled down, and the bucket shoot 13
rotates around the pin 15, is pulled upward (to the position indicated by the chain line in FIG. 2), and is stopped at a predetermined position by the contact operation of the limit switch 27,
Moreover, the stop position is maintained. When the bucket chute 13 is pulled up, the bulk items will fall directly below the chute body 8, and loading into the hold will be carried out as before. In the above embodiment, a motor cylinder is shown as an example of the bucket-shute actuating device.

As described in detail above, the present invention provides a chute having a predetermined inclination angle to the lowermost chute body which is rotatably supported so that it can be evacuated on-site at the drop opening, thereby allowing bulk materials to be transported into the hold of a ship using a simple device. It is possible to carry out a wide range of loading, and it has a great effect in contributing to improving the loading capacity of bulk material loading machines and reducing equipment costs. Further, in the present invention, a bucket chute having a U-shaped cross section is pivotally mounted to the lowermost chute body which can be driven and rotated, so that the inclined chute surface thereof extends below the discharge port and around the outer circumference of the lowermost chute body. At the same time, it is provided with an actuating device for rotating the bucket chute, and a bracket for locking the upper edge member of the side wall of the bucket chute is protruded from the lower end of the lowermost chute body, so that a bracket directly below the telescopic chute device is provided. When loading bulk goods, by storing the bucket chute on the outer periphery of the lowermost chute body, there is almost no protrusion below the lowermost chute body discharge port, and the chute body discharge port can be loaded close to the top of the cargo. In addition to being able to control the dust scattering,
During side point loading work, the impact force acting on the bucket chute is absorbed by the chute body, and the actuating device for rotating the bucket chute is hardly affected, so it can operate reliably and easily for a long period of time, and has many effects.
