Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle entry platform of a loading gantry for loading a construction vehicle such as a dump truck or a crane truck in underground construction.

[0002]

[Prior art]

 In the conventional boarding gantry, a slope that allows construction vehicles to enter from the general road onto the boarding gantry was constructed as shown in FIGS. 5 to 6.

That is, what is shown in FIG. 5 is a slope formed by placing concrete 3 in a range of a road occupancy width 2 of about 1 m extending from a site boundary line 1 of a building to a general road. In this case, the inclination angle α connecting the upper edge of the lining plate 5 laid on the upper girders 4 erected at appropriate intervals and the tip of the road occupation width 2 is limited to about 15 degrees. It is preferable to make the slope as gentle as possible.

On the other hand, the slope shown in FIG. 6 is used when it is not allowed to place concrete on the road occupation width 2 to form a permanent slope, or when the building is close to the site boundary line 1 When the slope slope is steep when used to the full extent, the slope 6 is made gentle by lowering the boarding gantry 7 by hitting the underground structure 6 afterwards.

[0005]

[Problems to be solved by the device]

 However, in the procedure of pouring concrete to form a slope, if there is not enough space on the site, it becomes a steep slope, which is inconvenient for the construction vehicles to enter. You have to lower 7. In such a case, the underground skeleton 6 is post-cast, which is not preferable in terms of quality. In addition, even if a slope is formed from concrete, it has to be repelled and removed later, which is troublesome.

The present invention has been made in view of the above problems, and is particularly effective when there is no room on the site, and it is easy to provide a slope for a construction vehicle of a boarding gantry, and Its purpose is to provide something that is easy to remove and hassle-free.

[0007]

[Means for Solving the Problems]

 The gist of the present invention to solve the above problems and achieve the above object is an entrance table having a triangular cross-section that forms a slope for a boarding gantry, the main body of which is divided into two parts, the front part and the front part. It is formed so that it can be evacuated to the rear body. In addition, the front and rear bodies that are divided into two parts are connected by hinges on the top surface. In addition, the front body is freely retractable in the hollow inside of the rear body.

[0008]

[Action]

 According to the approach table according to the present invention, when it is used as a normal slope, the entire length becomes long and the slope becomes gentle, which is suitable for a construction vehicle to enter the boarding gantry, etc. and is not used as a slope. Sometimes the entire length can be shortened to about half by folding the front body of the entry table to the rear body or retracting it by retracting it into the hollow interior.

[0009] Therefore, when the building is used over the entire site, even if the road occupancy width is used and the slope becomes a steep slope, the approach platform according to the present invention can be used from the boundary of the site to the road. When the construction vehicle is set over the occupied width and a slope is formed between the front body and the rear body when a construction vehicle enters the boarding gantry, etc., it will temporarily exceed the road occupied width and project to the center of the road. It can be a gentle slope. In other cases, by retracting the front main body to the rear main body, the entry platform can be accommodated within the range of the road occupation width.

[0010]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a use state of an access table 8 according to the present invention. The entry platform 8 has a triangular cross section to form a slope for the loading gantry 7, and is made of wood (for example, American softwood, a durable pine tree).

The main body of the entrance table 8 is divided into two at a substantially central portion into a front main body 9 and a rear main body 10, which are connected to each other by fixing a hinge 11 to the upper surface thereof with bolts or the like. To do.

The size of the entrance table 8 is about 2200 mm in total length, the height of the end is about 400 mm, and the width is about 350 mm. It weighs about 35 kg and is lightweight. As shown in FIG. 2, such an entrance platform 8 is installed in parallel on the road side of the boarding gantry 7 (using about 15 entry platforms 8) to form a gentle slope.

A step portion 12 is provided below the tip of the front body of the entrance table 8, and an operator uses the step portion 12 to put his or her hand on the front body 9. The hinge 11 is rotated around the center to be folded into the main body 10 on the rear side. Further, in order to prevent slipping, an arbitrary number of hulls 13 are driven on the surfaces of the front body 9 and the rear body 10 at appropriate intervals.

As shown in FIGS. 2 to 3, the entry platform 8 formed in this manner allows the front vehicle body 9 and the rear vehicle body 9 to move while the construction vehicle is entering or exiting the entry gantry 7. A slope is formed in 10 to make it a gentle slope that is easy to enter. Then, when the construction vehicle and the like are no longer going in and out, the front body 9 is put on the step portion 12 and rotated and folded, and the entrance table 8 is stored within the range of the road occupation width 2.

In this way, the entrance platform 8 is temporarily formed beyond the range of the road occupancy width 2. However, since it can be appropriately folded to reduce the overall length, it is a permanent one formed by pouring concrete. Not only that, it is easy to fit within the width of the road occupancy width 2, and it is easy to remove it.

Although the material of the entrance table 8 is made of wood as the best form of the material which is easy to handle and is lightweight, it is needless to say that it may be made of metal such as steel.

As another embodiment, as shown in FIG. 4, the front main body 9a may be housed in the hollow interior 10b of the rear main body 10a instead of the foldable type. A roller or the like is provided on the lower surface of the front body 9a for lateral movement.

In this way, when the front main body 9a is immersed in the hollow interior 10b, it is compact and fits well, which is convenient for handling such as transportation.

[0019]

[Effect of device]

 As described above, the vehicle entrance platform for the loading gantry according to the present invention is a platform having a triangular cross-section, the main body of which is divided into front and rear, and the front main body is retracted to the rear main body. Since it has been designed so that the building can be built over the entire site, it is possible to store the entry platform within the range of the road occupancy width, and there is no need to lower the boarding platform by hitting the underground structure afterwards. As a result, the quality of the underground structure can be maintained, which is advantageous in terms of cost and construction period. Moreover, even if the concrete for forming the slope is not allowed in the road occupation width, the approach platform of the present invention can be set within the range of the road occupation width without lowering the boarding gantry. It has an excellent effect that it can be used as a slope.

Since the front and rear bodies of the entrance block are divided into two parts by hinges on the upper surface, they can be easily folded and the overall length can be shortened to about half. This has an excellent effect that the work of temporarily changing the slope from the folded state can be done easily.

In addition, if the front body of the entry table is made to be retractable into the hollow inside of the rear body, the state in which the front body is retracted into the hollow becomes compact, It has an excellent effect that it is easy to handle during transportation.
