Abstract

PURPOSE:To reduce labor by automatically conducting a course of operations for elevating, transporting and unloading a container in an apparatus for transporting a container along a track and unloading the goods in the container at a predetermined position. CONSTITUTION:When a container 5 loaded with ores or the like is transported just under a track 2 by a truck, a crane 3 is travelled to be located just under the container 5. Subsequently, an elevating mechanism 35 such as an electrically- driven chain block is operated, and a support frame 39 is lowered, while being balanced by a pantograph balancing mechanism 38. The lowering is stopped when a support plate 47 of a support mechanism 45 passes through the lower end of a beam 53 of the container 5, and the support plate 47 is turned by an electrically-driven cylinder 49 to be engaged with the lower surface of the above beam 53. In such a condition, the container 5 is hung up to be transported to a predetermined position by running of the crane 3. After that, the container 5 is inclined by an electrically-driven cylinder 44, and a door 51 is opened to discharge ores or the like.

The operation of the embodiment of the present invention constructed as described above will be explained step by step as follows. It is assumed that the container 5 loaded with cargo is located directly below the track 2 in FIG. 1.

(1) Move the crane 6 and position it directly above the container 5.

(2) Operate the lifting mechanism 35 to lower the support frame 69. At this time, the balancing mechanism 38.38 is extended and keeps the support frame 39 horizontal at all times. When the support plate 47 of the support mechanism 45 passes the lower end of the beam 53 of the container 5, the support frame 69 is stopped.

(3) Activate the electric cylinder 49, 49, and the support plate 47
．． 47 into engagement with the underside of the beam 56.53 of the container 5 (see FIG. 6).

(4) Lift up the container 5 using the lifting mechanism 35.

At this time, the support frame 39. The container 5 is held horizontally by a balance mechanism 38. Furthermore, even if the cargo loaded in the container 5 is lopsided, it is kept horizontal by the stoppers 42 and 46.

(5) The crane 6 is driven by the travel motor 52a,
The container 5 is moved to a predetermined position t on a truck or the like Z.

(6) As shown in FIG. 5, actuate the electric cylinder 44, extend the actuator, and rotate the movable frame 40 clockwise about the arm 41.

When the movable frame 40 rotates, the bushing rod 5 of the container 5
8 is pushed down, the claw plate 56 is rotated clockwise via the lever 59 to release the engagement with the door 51. As a result, the door 51 rotates to the i-plane position due to its own weight, and a gap is formed between the door 51 and the main body of the container 50.

(7) When the movable frame 40 is further rotated by the electric cylinder 44, the container 5 is also tilted parallel to this.

The load 9 falls onto the truck or the like 7 through the opening.

(8) When the actuator of the electric cylinder 44 is returned to its original position after the cargo has been dropped (transshipped), the container 5 will return to the state shown in Fig. 2, and the claw plate 56 will engage with the door 51. lock.

(9) After moving the crane 6 in the opposite direction and stopping it at a predetermined position, the lifting mechanism 35 lifts the container 5 onto the floor (
or a rail truck), the electric cylinder 49 is operated to rotate the support plate 47 of the support mechanism 45, and the container 5
Remove from crane 3.

◇1 The empty container 5 is transferred to a predetermined location, and the crane 3 lifts and transports the next container 5 again.

In the above explanation, the operations of the present invention have been described in order for ease of understanding, but in actual operation, all of these series of operations are automatically performed by sequence control. In addition, although we have described the case of transporting and unloading ore and scrap, it goes without saying that other cargoes can be transported and unloaded in the same way. In addition, although we have shown the case where a pantograph method is adopted as the balancing mechanism,
Any mechanism other than this may be used as long as it can hold the support frame horizontally when moving up and down. Furthermore, although an electric cylinder is used to rotate the support plate and the movable frame of the support mechanism, a hydraulic cylinder, an air cylinder, etc. may also be used. It goes without saying that the mechanisms and shapes of other parts are not limited to the above embodiments, and may be modified as appropriate without departing from the gist of the present invention.

As is clear from the above description, according to the present invention, the lifting, transporting, and unloading of a container loaded with cargo can be carried out automatically and in a short time without the need for human power. Significant savings in costs and work time have become possible.
