Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading gantry that is temporarily installed for excavating a ground and then putting a construction vehicle such as a dump truck for carrying out sand or a material transport vehicle at a work site.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, in the above-mentioned loading gantry, the ground 20 is root-cut, and the mountain retaining wall 21 is raised and the beam 22 and the beam 23 are used as a support structure. The H-shaped steel shelf pile 24 supported by is driven into the ground 20. Then, the girder 25 is installed on the shelf pile 24, and the lining plate 26 is further provided thereon.
Is laid to construct the erection gantry 27. This construction gantry 27
The excavating machine 28 such as a clam cell is carried on the top, and the ground is carried out, loaded on a carrier such as a dump truck and dumped at a disposal site, or the material carrier carries in the material.

[0003]

However, in the above-mentioned boarding gantry, since it is fixed on the shelves, the cost is high, the construction period is long, and the space below the gantry is lower. However, there was a drawback that the work efficiency was poor because the materials could not be carried in and out.

The present invention has been made in view of the above-mentioned problems, and the work efficiency is improved by making the erection gantry movable to make the opening variable so that the gantry can be made compact and the cost can be reduced. The purpose is to provide a gantry.

[0005] SUMMARY for achieving a solution to the object above-mentioned object of the present invention, the upper end of the column to be erected on the space that will be formed by drilling the ground, digits in longitudinal and lateral directions in a horizontal plane In the embarkation gantry that is erected and is formed by laying a lining plate on the girder so as to cover the excavation opening surface,
Moving rails are laid on the girder in the front-rear and left-right directions at appropriate intervals to form a plurality of openings defining the excavation opening surface.

[0006]

[Operation] The movable loading gantry as described above is provided on the excavation opening surface.
According to example was driving into the gantry, moves to the right and left one or more longitudinal
By appropriately using or moving the movable movable loading / unloading gantry , it is possible to arbitrarily increase or decrease the working opening on the excavation opening surface , and to change the position of the opening. Become. This can correspond to the need for driving into the gantry accompanying the progress of the work.

[0007]

Next, the present invention will be described with reference to the drawings. The parts corresponding to the conventional example are given the same reference numerals. FIG. 1 is a plan view of a case where a movable pedestal gantry 1 according to the present invention is used. In order to form the movable loading gantry 1, as shown in FIG. 2, on the upper ends of the columns (shelf piles) 24 that are erected in the space 2 formed by excavating the ground 20,
A girder 25 is installed in the front-rear, left-right direction in the horizontal plane.

The moving rails 3 are laid on the girder 25 in the front-rear and left-right directions at appropriate intervals, and the excavation opening surface is, for example, 4 or more.
Forming a plurality of openings 11 divided into upper compartments
In addition, a flat plate-shaped pedestal base 4 having a lining plate 4a laid on the upper surface thereof
The open rollable casters 5 to the lower surface of fixed predetermined number
Forming a movable loading gantry 1 corresponding to the size of the mouth portion 11
I do. The movable loading gantry 1 has a sectioned digging opening surface.
At least one less than the number of openings 11
It will be prepared only for. For example, as shown in Figure 1.
The opening part of which the excavation opening surface is divided by the moving rail 3
Movable loading gantry when 11 are formed in 6 places in total
Prepare 3 pieces of 11 and set them on the moving rail 3
However, it is intended to cover a part of the excavation opening surface.
It Then , on the moving rail 3, the movable access structure
The gantry base 4 of the base 1 is movable in two directions of front, rear, left and right.

As shown in FIG. 3, the moving rail 3 has an upper U-shaped elongated channel as a main body 6, a plate 7 as a separating band is fixed to the central portion thereof, and an L-shaped rising portion is provided at the L-shaped rising portion.
It is formed by welding the mold angle 8.

As shown in FIG. 4, the caster 5 has its wheels made rotatable, and is rotatable in all directions in a horizontal plane. Further, there is a lock mechanism for moving the gantry base 4 in one direction, and the handle 9 fixes the direction.

In order to fix the position of the movable boarding gantry 1 on the moving rail 3, a lower end of the gantry base 4 and the angle 8 of the moving rail 3 are used as locking portions and a C-shaped clamp 10 is used. Fix it at an appropriate place.

[0012] Since the formation of the gantry 1 driving into this way movable, as shown in FIG. 5, in response to the gantry for base 4 of each movable driving into the gantry 1 to the request of the work site, FIG. (A), (b) ,
It can be moved so as to have a configuration as shown in (c) and fixed to the moving rail 3 by the clamp 10, and the earth and sand can be carried out and the material can be carried in through the desired opening 11. In addition to this, various variations such as changing the opening 11 to perform the work are included. It becomes possible to move the movable pedestal gantry 1 in a puzzle manner to proceed with the work. In addition,
Reference numeral 12 indicates a fixed gantry for a truck or the like to enter the site. Further, it is needless to say that the size of the movable pedestal gantry 1 can be determined according to the size of the work site and the number can be appropriately set.

[0013]

As described above, the boarding gantry according to the present invention is erected in the space formed by excavating the ground.
The girders are installed in the front, rear, left
And lining on the girder to cover the excavation opening surface.
In the boarding gantry formed by laying a board,
Laying at appropriate intervals movement rails in longitudinal and lateral directions above
When the excavation opening surface is divided to form a plurality of openings
In both cases, a flat plate rectangular structure corresponding to the size of the opening is used.
Attach the required number of casters that can freely rotate and roll in all directions in a horizontal plane to the lower surface of the base for the base and attach it to the upper surface of the base for the base.
Form a movable boarding gantry with a lining plate,
At least one less than the number of partitioned openings
On the moving rail on the excavation opening surface.
Equipped with, since it is possible to provide an opening for working in any position, it improves work efficiency. Traditional fixed
In the case of a gantry, or a direction orthogonal to the approach direction of a vehicle, etc.
The excavation opening face, as in the case of a gantry that can only be moved to
It is complicated and difficult to say, or it can only be opened in one direction.
If you can not make it open, make the excavation opening surface fine
There was an inconvenience that it could not be opened. to this
On the other hand, in the present invention, a plurality of openings are formed and
I can freely move the movable boarding gantry with a puzzle type
Since it is so, the size of the opening area and the opening position can be changed.
With the excellent effect that it can be done, it is possible to say that the work under the pedestal is difficult to perform. Before
Since the movable loading gantry can be diverted, it can be used immediately at other work sites if the rail width is adjusted, which shortens the construction period. In addition, if the boarding gantry of the present invention is used for road surface lining, it is convenient and easy to change the running path and save time and effort.
