Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a continuous unloader suitable for landing bulk material in a ship's hold, and in particular, a bulldozer for scraping the bulk material in the ship's carry-in into the ship's hold. It is about a continuous unloader that can.

[Prior Art] Conventionally, a bulldozer has been used to scrape away the bulk material remaining in a ship's hold in a bulk material handling operation by a continuous unloader.

In order to carry the bulldozer into the boat, for example, in the bucket elevator type continuous unloader, the bulldozer is hung and carried through the lower end of the bucket elevator via a hanger.

[Problems to be Solved by the Invention] However, when the bulldozer is suspended from the lower end of the bucket elevator, a space is required for suspending the bulldozer from the lower end of the bucket elevator.

For this reason, when the bulldozer is hung at the lower end of the bucket elevator and carried into the ship's hold, it is necessary to raise the height of the boom accordingly.

However, in order to raise the boom, it is necessary to increase the hoisting angle of the boom or raise the pivot point of the boom, which is inevitable from the design and manufacturing point of view.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to carry a bulldozer into a boat without changing the boom hoisting angle of the unloader or the boom pivot point. It is intended to provide a continuous unloader that can.

[Means for Solving the Problems] In order to achieve the above object, a continuous unloader according to the present invention is a continuous unloader in which a vertical frame is hung on the tip of a boom, and the vertical frame is perpendicular to the vertical frame. A penetrating hole is provided, a suspension beam is slidably inserted into the penetrating hole, a drive device for moving the suspension beam forward and backward is provided on the vertical frame, and a suspending tool is provided at the tip of the suspension beam. Is provided.

Further, a support beam is provided on the upper side of the through hole of the vertical frame along the advancing / retreating direction of the suspension beam, and a U-shaped receiving member is formed on the lower surface of the tip of the support beam so that the suspension beam can pass through. Is provided.

[Embodiment] An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is an overall view of a bucket elevator type continuous unloader, in which 1 is a traveling platform that travels on a rail 2 laid on a quay, and a boom 4 can be undulated on the traveling platform via a revolving frame 3. It is provided in.

A vertical frame 6 is hung at the tip of the boom 4 via an L-shaped frame 5, and a bucket elevator 7 is supported by the vertical frame 6. 8 is a ship docked on the quay.

The vertical frame 6 is provided with a through hole 13 penetrating so as to be orthogonal to the vertical frame 6, and the suspension beam 11 is slidably inserted through the through hole 13. Further, the vertical frame 6 is provided with a drive device 19 for moving the suspension beam 11 back and forth.

The drive device 19 is composed of a hydraulic cylinder 20 in this embodiment, and the hydraulic cylinder 20 is attached to the vertical frame 6 below one end of the through hole 13 via a bracket.
The tip of the piston is connected to the tip of the suspension beam 11 via a bracket.

The hydraulic cylinder 20 is connected to a hydraulic pressure source via a pipe.

The through hole 13 is provided at a fixed distance L from the lower end of the vertical frame 6, that is, at a height necessary for suspending the conveyed product 10.

A guide plate 14 is provided on the inner peripheral surface of the through hole 13 either entirely or at intervals.

The suspension beam 11 has a contact surface that abuts the guide plate 14 smoothly machined so that the suspension beam 11 can slide smoothly on the guide plate 14. Further, a suspending tool 18 for suspending the transported object 10 (a suspension ring in the embodiment, but a hook may be used) is attached to the tip of the suspension beam 11.

Further, in the embodiment, the example in which the through hole 13 through which the suspension beam 11 penetrates is provided in the vertical frame 6, but when the width of the vertical frame 6 is narrow and the distance between the fulcrums supporting the suspension beam 11 is too short. Is a through hole 13 of the vertical frame 6 as shown in FIG.
The support beam along the direction of advance / retreat of the hanging beam 11 on the upper side of the
15 and a receiving member 16 provided on the lower surface of the tip of the supporting beam 15 and formed in a U shape so that the hanging beam 11 can pass therethrough. You may make it wide. Reference numeral 17 is a guide plate provided on the inner peripheral surface of the receiving member 16.

Although the drive device 19 is composed of the cylinder 20, it may be replaced with a screw jack system or a rack and pinion system.

[Operation] When carrying the transported article 10 into the ship's hold, first, the bucket elevator 7 is brought to a position directly above the transported article 10 to be transported.

Next, the suspension beam 11 is moved to the vertical frame 6 by the driving device 19.
With the tip of the suspended beam 11 positioned right above the transported object 10 while bulging and swinging the boom 4 up and down and at the time when the lower end of the bucket elevator 7 is on the ground or just before it is on the ground. Stop the boom.

After that, the transported object 10 and the suspension ring 18 are connected with a wire rope,
The conveyed article 10 is carried into the boat hold of the vessel 8 while the boom 4 is raised and lowered and turned. When the conveyed product 10 is carried into the ship's hold, the wire rope is removed to separate the hanging ring 18 and the conveyed product 10.
Then, if the transported object 10 is a bulldozer, the bulk materials in the ship's hold are scraped, and the suspension beam 11 is moved to the vertical frame 6 side by the drive device 19.

When carrying out the conveyed article 10 from the inside of the ship, the above-mentioned carrying-in operation may be performed in reverse.

[Advantage of the Invention] As described above, in the present invention, the hanging beam is attached to the vertical frame at a certain distance from the lower end of the vertical frame (the distance from the lower end of the transported object to the upper end of the wire rope), and the hanging beam is hung on the vertical frame. Since it is possible to carry in and out by carrying out, it is not necessary to take an extra space from the lower end of the vertical frame for carrying the goods, and there is no restriction on the design and manufacture of the unloader.

Further, since the suspension beam can be retracted with respect to the vertical frame, the conventional cargo handling work can be performed without any restriction.
