Description

[Detailed description of the invention] (Field of industrial application) This invention is used in container cranes, transfer cranes, etc., to transport suspended loads (containers, etc.) This invention relates to a hanging load guide device that guides a load onto a loading platform.

(Prior art) Cargo handling operations using container cranes, transfer cranes, etc. on quays or in yards are
In general, there is work in which loads such as containers are suspended and transported by the main hoisting rope of a crane, and then loaded onto a transport machine such as a trailer on the ground. Due to changes in the lowering position of the suspended load, it is difficult to load onto the loading platform of the ground-side transport machine, and a suspended load guide device that accurately guides the suspended load onto the loading platform has been proposed (for example,
Special Publication No. 53-37616).

In the conventional example of the hanging load guide device, the lower part of the hanging load guide pivotally connected to the base is swung by an actuating cylinder so as to come into contact with the loading platform of the ground-side conveyor,
The structure is such that the suspended load suspended and lowered by the main winding rope is guided to a desired position on the loading platform by the guidance of the suspended load guide.

(Problems to be solved by the invention) The above-mentioned conventional hanging load guide device has a structure in which the upper part of the hanging load guide is placed at a specific position and the lower part is oscillated. If the stopping position of the machine is far apart, the lower part of the load guide cannot touch the loading platform of the transporter, making it difficult to stop the transporter. There are problems in that it is necessary to change the method, or it is necessary to equip each of the plurality of lanes.

(Means for solving the problem) This proposal is an invention to deal with the above-mentioned problems, in which a movable frame is suspended from the crane leg via a horizontal movement mechanism, and the mobile frame is suspended from the crane leg via a horizontal movement mechanism. By pivotally mounting a hanging load guide at the bottom that is swung by a drive mechanism and comes into contact with the loading platform, the movable frame, ie, the hanging load guide, can be arranged in relation to the loading platform stop position of the ground-side conveyor and its lane change. And the movement can be adjusted freely, improving the suspended load guiding performance and cargo handling efficiency, and solving the above-mentioned problems.

(Operation) The horizontal movement mechanism adjusts the movement of the movable frame and approaches the carrier that is stopped under the crane, and the drive mechanism swings the lower part of the hanging load guide so that it comes into contact with the platform of the carrier. Then, the suspended load that is lowered by the main hoisting rope of the crane is guided by the suspended load guide and is accurately loaded onto a desired position on the loading platform.
Furthermore, when changing lanes, the same handling is performed and the same suspended load guiding function is achieved.

(Embodiment) An embodiment of the present invention is shown in Figs. 1 to 3, in which 1 is a leg of a container crane, 1a is a horizontal member provided between the legs, and 1 and 2 are horizontal members. As shown in the figure, a plurality of moving vehicles 3 with upper and lower wheels 2 are horizontally movably mounted on horizontal members 1a, 1a, and sprockets 4 are provided at both ends of the horizontal members 1a.
Both ends of the chain 5, which runs between the sprockets 4a and 4b, are connected to both sides of the moving vehicle 3, and as shown in FIG. Forward/reverse motor 3 via sprocket 27 and reducer 28
0, a brake 29 is attached to the motor 30, and the chain 5 is driven in the forward and reverse directions by forward and reverse rotation of the motor 30, and the moving vehicle 3 is horizontally moved left and right as shown in the figure on the horizontal member 1a. A horizontal movement mechanism is provided on the crane leg to stop the crane.

Furthermore, as shown in FIGS. 1 and 2, a movable frame 10 is integrally suspended from the movable vehicle 3 of the horizontal movement mechanism, and a pin 11 is attached to the lower part of the movable frame 10 to suspend a load. The upper part of the guide 12 is pivotally connected, and a hydraulic cylinder 13 is connected with a pin between the lower end of the movable frame 10 and the hanging load guide 12, and the hydraulic cylinder 13 connected to the hydraulic unit 15 is operated to expand and contract. Therefore, the lower part of the hanging load guide 12 is swung to come into contact with the side of the loading platform a of a ground-side conveyor, for example, a container trailer.

The embodiment of the present invention has the above-mentioned configuration, and when a transport machine, for example, a container trailer, stops under the crane, the horizontal movement mechanism horizontally moves the movable frame 10 together with the mobile vehicle 3 to move the container trailer. The lower end of the suspended load guide 12 is brought into contact with the loading platform a of the container trailer by the extension of the hydraulic cylinder 13, and the suspended load guide 12 is brought into a suspended load guiding position. When a suspended load suspended by the main hoisting rope of the crane is lowered, the suspended load moves to the suspended load guide 12,
12 and loaded onto a desired position on the loading platform a.

Even when there are a plurality of chassis lanes under the crane, lanes can be easily changed by horizontally moving the movable frame 10.

The movable frame is integrally suspended from the movable vehicle, and is vertically adjustable with respect to the movable vehicle.
Alternatively, a configuration may be provided in which a telescopic mechanism is provided so that the lower end of the hanging load guide can be adjusted up and down with respect to the loading platform of the transport vehicle.

(Effects of the invention) Since the present invention has the above-mentioned configuration, the horizontal movement mechanism moves the movable frame and the hanging load guide close to the loading platform of the ground-side transport machine, and the drive mechanism moves the lifting load guide close to the loading platform of the ground transport machine. By bringing the load guide into contact with the loading platform, the suspended load guide can be simply and easily disposed, lane changes can be easily handled, the suspended load guiding performance is significantly improved, and the cargo handling efficiency is greatly increased.
