This invention relates to a sleeper loading and unloading device for temporarily storing the sleepers during such work.

Currently, when long materials such as steel materials are piled up and stored, sleepers are used to prevent the cargo from collapsing and to reduce damage to the long materials.

For this purpose, it is necessary to place sleepers at certain positions and to remove the sleepers.

However, there is no cargo handling equipment suitable for this (all cargo handling work for such sleepers is done manually.

Not only is there a loss of labor and time required for manually transporting and aligning sleepers, but working at heights under a turret, that is, manual labor on long timbers piled high, is
Extremely high risk.

In order to avoid this danger, a falling sleeper supply device has been devised for placing sleepers at specific positions.

However, there is no device that has been able to perform the reverse operation, that is, the collection of sleepers and the function of storing the sleepers, using the same device, and has achieved the same work as manual labor.

There is no cargo handling equipment that is suitable for cargo handling of sleepers, is highly flexible, easy to use, and can be used freely in large-scale long material storage yards where overhead cranes are used. The current situation is that this is not the case.

In view of the above points, the present invention provides a sleeper grasping and unloading device that can realize the grasping, unloading, and storage of sleepers with high efficiency and high reliability in a large-scale long material storage yard using the same device. The purpose is to provide.

The present invention is characterized in that an opening is provided below the frame body through which the sleeper to be handled can be taken in and out, a guide frame for the sleeper is provided in the center of the frame above this opening, and frames on both sides of the opening are provided. A pair of gripping means that can be moved in the vertical direction and can be opened and closed in a direction perpendicular to the longitudinal direction of the sleeper, and a pair of locking means that can be opened and closed in a direction perpendicular to the longitudinal direction of the sleeper are mounted on the guide frame. The gripping means grips the sleepers upward and lowers them down, and the locking means allows the sleepers to be stacked and stored.

The detailed structure inside the frame 1 will be explained with reference to FIGS. 2 to 5.

As described above, the frame body 1 is attached to the lower end of the support section 2.

An opening 3 shaped along the longitudinal direction of the sleeper M is formed below the frame 1.

This opening 3B is provided wider than the width of the sleeper M.

In the longitudinal middle part of the sleeper M on both sides of this opening, a pair of gripping means 4 facing each other in a water-like manner as shown in FIG. 3 is arranged, and on both sides thereof, locking means 5 are arranged. .

Next, the structure of the gripping means 4 will be described in detail with reference to FIGS. 2 to 4. A finger 6 having a portion for pressing the sleeper M is attached to the tip of a rod 7 projecting in the horizontal direction.

Said rod 7 is moved by a gripping cylinder 8 a fixed distance in the direction of arrow A.

Therefore, the opposing fingers 6 open and close in a direction perpendicular to the longitudinal direction of the sleeper M to grasp and release the sleeper M.

A plurality of the gripping cylinders 8 are mounted on the same guide base 9, as shown in FIGS. 3 and 4.

Therefore, the sleepers M can be reliably grasped from multiple points.

Further, the entire guide base 9 is installed at the lower end of the rod 11 of the lifting cylinder 10 and is moved up and down along the guide rod 12.

The lifting cylinder 10 is fixed to a frame 13.

With this configuration, the left and right pair of fingers 6 are closed and the sleeper M
When grasped or opened, it moves up and down synchronously and is controlled to move and stop at a specified height.

Next, the structure of the locking means 5 will be explained with particular reference to FIGS. 3 and 5.

As shown in FIG. 3, this locking means 5 is disposed at a position shifted from the gripping means 4 at 5. As shown in FIG.

A locking member 14 for locking the sleeper M from falling is moved a fixed distance in the direction of arrow B by a locking cylinder 15, as shown in FIGS. 3 and 5.

This locking cylinder 15 is fixed to the frame 1.

With this configuration, the opposing locking members 14 open and close in a direction perpendicular to the longitudinal direction of the sleeper M to support and move the sleeper M through.

In the frame 1 above the locking member 14, guide frames 16 are provided vertically on both sides of the opening 3.

This guide frame 16 is for arranging the sleepers M which are stacked and stored, and sequentially carrying out a gripping and unloading operation.

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

First, the operation of picking up the upper sleeper M on a long piece of material will be explained.

When the fingers 6 are in the open position with respect to the sleeper M indicated by the symbol A, which is placed approximately horizontally at an arbitrary position on a long piece of material, the opening 3 of the frame 1 is located directly above the sleeper M. Align the frame 1 so that

Thereafter, the fingers 6 are lowered by the lifting cylinder 10 and positioned at a height where the sleepers M can be grasped.

Next, by extending the gripping cylinder 80 rod 7 and closing the hook/gallon, as shown in FIG.
