The present invention relates to a long object and sleeper loading and unloading device capable of unloading, unloading, and grasping and unloading of various types and large quantities of long objects.

Currently, this type of work is mostly done manually, and there is no equipment that can simultaneously handle and transport long objects such as steel materials and railroad ties.

The applicant has already proposed various mechanisms and control systems for the long object handling device used in the present invention.

Furthermore, the sleeper handling device has been newly devised by the applicant as being of the same level (labor saving, automation) suitable for this long object handling device.

As mentioned above, in order to handle long objects and sleepers in a yard that follows conventional cargo handling and storage methods,
The key issues are the appropriate combination of equipment and methods for multiple tasks.

From this point of view, the reality is that none of the conventional devices has been sufficiently studied from a functional standpoint.

In view of the above points, the present invention aims to quickly and accurately perform the four operations of scooping and unloading steel materials and railroad ties using the two cargo handling devices, either manually by a crane driver or automatically. It is.

In other words, it streamlines dangerous and harsh manual labor such as loading and unloading of long items using wire robes (loosening, unloading) and loading and unloading of railroad ties (grabbing, unloading, and storing), while still using conventional loading and unloading equipment and storage formats. The aim is to achieve this through a simple mechanism and control.

The present invention has the following features.

That is, the apparatus of the present invention is composed of three parts: a long object handling device, a sleeper loading device, and a driver's cab.

A sprocket 2 is attached to the roller shaft of these 26 groups of rollers.
7a to 27f are connected by chain 28,
Rotates forward and backward or is stopped.

The number and spacing of these roller 26 groups, 1, is to prevent the sleeper 2 from falling when the roller 26 group is stopped, and to ensure that the sleeper 2 moves smoothly up and down when the row 226 group is rotated in forward and reverse directions. It is determined by the dimensions of the sleeper 2 and the number of 20 sleepers to be stocked so that

An opening/closing frame 30 supported by a hinge 29 is attached to the lower end of the main frame 25 so as to enlarge the downward opening.

This opening/closing frame 30 is connected to the fifth opening/closing cylinder 31.

As shown in FIG. 6, this stopper 32 is rotated in the horizontal direction by a stopper opening/closing cylinder 33 about a shaft 34 as a fulcrum, and moved into and out of the frame 30.

When the work of putting in and taking out sleeper 2 is finished, the sleeper 2
When transporting the sleepers 2, by extending these stoppers 32, it is possible to prevent the sleepers 2 from falling.

Length W and height H of roller 26 group of sleeper cargo handling device 12
As shown in FIG. 7, is determined from physical quantities such as the number of sleepers 2 in stock, dimensions, and weights so that the sleepers can be reliably put in and taken out and stored.

FIG. 8 shows another example of the sleeper cargo handling device 12, in which a belt is arranged in place of the group of rollers 26.

That is, a pulley 38 rotated by a sprocket 31 connected to a driving sprocket 35 and a chino 36.
As a result, the endless belt 39 is rotated in forward and reverse directions and stopped.

With this configuration, the sleeper 2 can be pulled in, pushed out, and stored as in the case of the rollers 26 described above.

Even when using the belt in this way, the main frame 25
By providing an opening/closing frame 30 at the lower end and installing a belt 39 which can also be rotated in forward and backward directions, alignment with respect to the railroad ties is facilitated.

By making the above-mentioned dimensions variable according to the dimensions of various sleepers, the same effect as described above can be performed on sleepers of any size.

Its configuration is shown in FIGS. 9 and 10. In this figure, the main frame 25 is divided into main frames 25a and 25b, and supported by a horizontal frame 40 so as to be slidable in the horizontal direction.

These main frames 25a, 25b are cylinders 41a.

41b allows alignment so that the dimensions are suitable for holding the sleeper 2.

As mentioned above, the sleeper handling device according to the present invention is extremely flexible, and when used alone without being limited to sleeper cargo handling, it can be used with various cross-sectional shapes such as square timbers, long timbers, pipes, etc. A similar cargo handling method is also possible for items having certain dimensions, and the effects described below can be obtained.

Next, the operation of the long article cargo handling apparatus according to the present invention will be explained.

The hanging tool 8 is kept in a state where the forks 9a and 9b are retracted.

In this state, while detecting the gap between the long objects using the photoelectric switches 22a s 22b, the position of the spreader 7 is automatically corrected and inserted between the long objects.

Next is the photoelectric switch 21a. 21b, the gap between the upper and lower elongated objects is detected, the lowering of the spreader 7 is stopped, and the alignment of the forks 9a and 9b is completed.

At this position, the forks 9a and 9b are taken out and the bottom surface of the long object 1 is scooped up.

The above is the work procedure for loosening a long object, but when unloading a long object, with the long object 1 held on the hanging tool 8,
By performing a similar operation using the same detection method as described above and retracting the forks 9a and 9b, a 70-long object can be unloaded.

The above operations can be performed automatically.

Prior to the work of grasping and unloading the long object 1, it is necessary to grasp and unload the railroad ties 2.

That is, when grabbing a long object 1, place the sleeper 2 on top of the long object.
When unloading the long object 1, it is necessary that the sleeper 2 is placed at the position where it is to be unloaded.

The operation procedure for picking up the sleeper 2 from the long object 1 will be explained with reference to FIG.

The sleepers 2, which have been stocked in advance in the opening/closing frame 30 in the sleeper handling device 12, are pulled upward by the rotation of the group of rollers 26.

Then, with the opening/closing frame 30 open, the sleeper 2 placed on the long object is roughly aligned in the horizontal plane.

That is, after aligning the longitudinal direction of the sleeper 2 with the longitudinal direction of the lower opening, the sleeper cargo handling device 12 is lowered and the sleeper 2 is stored in the opening/closing frame 30.

Thereafter, the opening/closing frame 30 is closed, and the group of rollers 26 within the opening/closing frame 30 is driven to rotate.

Thereby, the sleepers 2 are sent upward and are stocked inside the sleeper cargo handling device 12.

Thereafter, by releasing the stopper 32 at the lower end of the device 12, the sleeper 2 can be prevented from falling during transportation.

Performing such an operation while moving the device 12 sideways,
Several sleepers 2 arranged in the longitudinal direction of a long object can be picked up one after another quickly, smoothly, and efficiently without the need for manpower.

Next, the operating procedure for removing the sleepers 2 will be explained with reference to FIG.

In advance, the sleepers 2 stocked in the opening/closing frame 30 of the sleeper cargo handling device 12 are lowered downward by rotational driving by the group of rollers 26.

Then, the sleeper handling device 12 is positioned at a horizontal position on the long object 1 from which the sleeper 2 is to be unloaded.

Thereafter, the stopper 32 at the lower end is retracted, and the group of rollers 26 in the opening/closing frame 30 is driven to rotate, thereby pushing out the railroad ties 2 and the like in the opening/closing frame 30 downward.

Performing such an operation while moving the device 12 sideways,
The required number of sleepers 2 in the longitudinal direction of the long object are sequentially
Wholesaling can be carried out quickly, smoothly, and efficiently without the need for manpower.

The above operations are performed by visual manual operation from the operator's cab.
Although it is flexible, it can also be done automatically.

For the above-mentioned work such as fixing long objects and sleepers, unloading work, and aligning the crane body to the specified position,
It is operated by a control panel 13 or a console 14 housed in a driver's cab 15.

According to the present invention, it is possible to completely eliminate inefficient and dangerous work such as slinging long objects and manual work on sleepers, which was conventionally performed by several ground workers in a long object yard. .

In other words, the work of slinging with wire roses is automated by a long object handling device that moves the fork in and out using a positioning detector, which significantly improves work efficiency.
Safe and reliable cargo handling and transportation becomes possible.

In addition, in order to maintain the advantages of the conventional storage format, a sleeper loading and unloading device will be installed, eliminating the labor required to grab and unload the sleepers and transport them, which will greatly promote rationalization at this point.

In addition, it is possible to stock the sleepers in the device, thereby eliminating the factor that prolongs the working time.

In addition, the present invention realizes highly flexible and versatile cargo handling operations even when a single crane operator visually operates the crane.
It is also possible to perform cargo handling operations more rationally through automatic operation.
