Description

[Detailed Description of the Invention] The present invention is made by bundling one to several long objects such as H-beams, sheet piles, rails, and pipes, and inserting sleepers at appropriate positions so that they can be stacked fairly densely. This invention relates to a sleeper handling device that performs the work of grabbing and unloading sleepers in a storage yard for long items in which long objects are stored.

Currently, all of this type of work is done manually, and there is no equipment that can streamline the handling and transportation of steel materials and sleepers.

As mentioned above, in a long goods yard that follows the conventional cargo handling and storage method, in order to handle long goods and sleepers, appropriate equipment is combined for each, and combined work is carried out in an orderly manner. Work can be done quickly and reliably.

From this point of view, it has been found that the above-mentioned effects cannot be obtained with conventional equipment because there is no device that has been sufficiently studied.

For cargo handling of long items, we use wire rope shade automation,
The use of a fork has been devised, but it is not sufficient.

In order to efficiently carry out sleeper cargo handling work in combination with a long object handling device, the functions of grasping, unloading, and storing sleepers must be realized with a simple and reliable device.

The present invention is capable of automatically picking up sleepers on a long object or lowering them to a desired position, and storing a certain number of sleepers therein, facilitating ground work for transporting and handling sleepers. To provide a sleeper cargo handling device which can completely eliminate the need for personnel and can perform work quickly and accurately.

When the sleeper cargo handling device of the present invention is used in conjunction with a long object cargo handling device, the most efficient cargo handling work can be performed.

Therefore, in a cargo handling equipment equipped with a long object cargo handling device and a sleeper cargo handling device, the device of the present invention can be used to locate a predetermined sleeper to be picked up or Traveling, traversing, and stopping at a predetermined position are performed with respect to the position where the robot is to be unloaded.

After being approximately positioned in this manner, in the apparatus of the present invention, two opposing
By the vertical spacing movement of the set of beams, it is possible to grab a sleeper placed on a long object upwards inside the building, or to take a stored sleeper downwards to the outside.

Also, when the system is not in operation, a set of beams can support a certain number of sleepers.

Since these operations can be carried out automatically according to commands, it is possible to eliminate the need for manpower used in the work of loading and unloading railroad ties in the yard, and the work can be carried out in an extremely short period of time.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of one row of devices of the invention.

The sleeper cargo handling device 1 is normally mounted on cargo handling equipment such as an overhead crane, and suspended by a telescopic guide, wire rope, or the like.

That is, the apparatus of the present invention is moved to a predetermined position and stopped by operating the crane Q or by a moving device (not shown) provided in the entire apparatus.

Then, at a predetermined position, that is, a position where the sleeper is grasped or taken down, the action of passing or taking down the sleeper 3 on the elongated object 2 as shown in the figure can be performed by the mechanism described below.

Details of one embodiment of the apparatus of the present invention will be described with reference to FIGS. 2-4.

In the figure, the main frame 4 is provided with an opening 1b having a width appropriate to the width of the sleeper 3 on the side and lower surfaces.

Three sets of beams 6.9.12 are mounted on both inner side surfaces of the main frame 1a and are reciprocated vertically in an intermittent manner.

The clamping beam 9 protrudes downward from the main frame 4 at its lowest point, and is kept vertically by a guide 8 mounted on the vertically movable beam 6. , can be moved horizontally while remaining vertical.

That is, when the cylinder 7 is extended, the clamping beam 9 can collectively clamp sections I to H of the sleepers 3, and when it is contracted, it moves to a position where it releases them.

With the vertically movable beam 6 supporting the clamping beam 9,
It is kept vertical by guide 5 and still has cylinder 4
It can move up and down while remaining vertical as it expands and contracts.

That is, when the cylinder 4a is extended, the vertically movable beam 6 moves the clamping beam 9 to the lowest sleeper gripping position, and when the cylinder 4a is retracted, it moves the clamping beam 9 upward by the height of the sleeper.

On the other hand, the support beam 12 is installed on the main frame 1a completely independently of the beam 6.9, and is kept in the vertical direction by the guide 11, and as the cylinder 10 expands and contracts, the support beam 12 moves horizontally. It can move freely in any direction.

That is, when the cylinder 10 is extended, the beam 12 can collectively hold the ends of the sleepers 2, as shown in FIG. 3, and when it is contracted, it moves to a position where they are released.

Depending on the number of 30 sleepers to be stored, the above beam 6.9
．． The length of 12 is determined.

In addition, the vertical and horizontal movement distance of the beam 6.9.12 and the arrangement of the beam 6.9.12 in the longitudinal direction of the sleeper 3 are determined by the dimensions (length, width, height) of the sleeper 30. It is.

Therefore, driving by the illustrated cylinder is also possible by driving by an electric motor, and the shape (presence or absence of protrusions) and arrangement (number) of each beam 6, 9, 12 can also be changed freely.

Next, the operation of the apparatus of the present invention will be explained.

First, the operation of picking up the sleeper 3 on the long object 2 will be explained.

In FIG. 3, sleepers 30, C and 2 are already held by the support beam 12.

That is, the support beam is moved to the forefront position by a cylinder 10, and the projections on the beam 12 sort and support the sleepers 3 at regular intervals.

Furthermore, the clamping beam 9 is in the lowermost position, being retracted by the cylinder 1.

In this state, as shown in FIG. 3, the main frame 1a is aligned so that A of the sleeper 3 is located between the clamping beams 9.

From this state, by extending the cylinder 7, the clamping beam 9 clamps the crossties of the sleepers 3 with enough pressure to prevent them from falling.

Therefore, even if the support beam 12 retreats after this, the sleeper 3
is kept in the same position.

Next, as the cylinder 4 contracts, the clamping beam 9 moves upward together with the vertically movable beam 6 by the height of the sleeper 3 and stops, as shown in FIG.

That is, the corners C, B, and B of sleeper 3 are moved to position E.

Next, as the cylinders 10 extend, these sleepers 3 are reliably supported by the support beams 12 so as not to fall.

Thereafter, due to the contraction of the cylinder 7 and the expansion of the cylinder 4, the state returns to the state shown in FIG. 3 again.

Through these series of operations, the sleepers 3 on the long object 2 are picked up into the device and held at the positions indicated by the code openings, and each sleeper 3 is also sent upward, so that the sleepers 30 are , Ha is held at 2, and 2 is held at E.

Next, in Fig. 3, the mouth of the stored sleeper 3 is
The operation of lowering it to position A will be explained.

In FIG. 3, the lowermost clamping beam 9 is moved upward in a retracted state.

When the clamping beam 9 moves to the height of the sleeper 3, the extension of the clamping cylinder 7 causes the clamping beam 9 to clamp the ends of the sleeper 3 with enough pressure to prevent them from falling.

Therefore, even if the support beam 12 is moved back thereafter, the sleeper openings 1 to 2 are held in the same position as shown in FIG. 5.

Next, as the cylinder 4 extends, the clamping beam 9 moves downward together with the vertically movable beam 6 by the height of the sleeper 3 and then stops.

That is, the 30th sleeper is moved to the A position, the 3rd sleeper is moved to the B position, and the 2nd sleeper is moved to the C position.

Next, by extending these sleepers 3 and cylinder 10, sleepers 3 and 3 are reliably supported by the support beams 12 so that they do not fall.

After this, due to the contraction of the cylinder 7, only the 30 sleepers remain in the position A, returning to the state shown in FIG. 3.

Through these series of operations, the 30 sleepers are lowered onto the steel material 2, each sleeper 3 is sent downward, and the sleepers 3 are held at the opening position and the second position.

It should be noted that the present invention is applicable not only to the unloading of sleepers in a yard, but also to the unloading of various types of wood, steel, etc. having rectangular or circular cross sections.

According to the present invention, the sleepers can be moved upward or downward and the sleepers can be stored by the vertical reciprocating motion of two sets of beams and their clamping action.

That is, with an extremely simple structure and drive mechanism, conventionally,
It eliminates the need for manual labor such as transporting, positioning, raising and lowering sleepers, and contributes to streamlining the yard for long items, making it extremely useful.

In particular, the ability to position the sleepers, their flexibility, the ability to hold a large number of sleepers inside them, and the ease of control ensure better work efficiency and reliability than manual work. .
