Abstract

PROBLEM TO BE SOLVED: To prevent sediments form remaining in a sediment compartment by providing stainless steel inner plates in the inner bottom surface and the inner wall surface of the sediment compartment so as to prevent the sediment from being stuck in the recessed and projecting parts of the inner plates. SOLUTION: For one side wall part of a sediment compartment 1, a side full surface is formed to be a side wall opening 6 by removing the side wall part, a side wall door plate 7 is provided in this side wall opening 6, and this side wall door plate 7 is fixed to the upper part of the side wall opening 6 of both end walls 9 of the sediment compartment 1 by an axial fixing mechanism. Further, stainless steel inner plates 5 are provided in the inner bottom surface 3 and the inner wall surface 4 of the sediment compartment 1. Thus, even if sediment 15 are stuck to the inner plates 5, since there are no recessed and projecting parts in the inner plates 5, the sediments 15 are peeled off from the inner plates 5 and dropped from the side wall opening 6 and thus remaining of the sediments 15 in the sediment compartment 1 is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sediment loading room such as a sediment transport vehicle used for carrying out relatively viscous sediment discharged in subway construction or the like.

[0002]

2. Description of the Related Art Conventionally, when a large amount of earth and sand is discharged, such as in subway construction, a rollover steel car as shown in FIG. 3 has been used for carrying out the earth and sand.

[0003] The rollover type steel wheel is provided with a sediment loading chamber 1 having an opening 2 at an upper portion, and the earth and sand excavated at a ground excavation site is loaded into the sediment loading chamber 1 and loaded. Then, the overturned steel car is driven to an accumulation site for taking out earth and sand onto the ground.

[0004] Then, the earth and sand loading chamber 1 is rotated by a roll mechanism (not shown) with the roll axis 8 as the center of roll, and FIG.
It is turned over as shown by the dashed line, and the inner bottom surface 3 of the sediment loading chamber 1 is tilted, and the sediment 15 loaded in the sediment loading chamber 1 is passed through the opened side wall opening 6 of the side wall door plate 7 so that the sediment loading chamber 1 It is discharged to the outside.

[0005]

However, when the earth and sand 15 loaded in the earth and sand loading chamber 1 is low viscosity earth and sand 15, there is not much problem.

However, when the sediment 15 to be loaded is highly viscous sediment 15, even if the sediment loading room 1 is turned over and the inner bottom surface 3 of the sediment loading room 1 is tilted, the sediment 15 remains
Due to the pressure caused by the weight of the earth and sand 15 and the minute vibration of the earth and sand loading chamber 1, they adhere to the inner bottom surface 3 or the inner wall surface 4 of the earth and sand loading room 1 without gaps and remain without falling.

A urethane plate or a rubber plate was stretched on the inner surface of the sediment loading chamber 1 so that the earth and sand would not adhere, but there was almost no effect. The present invention has been made in view of the above, and even if the soil is highly viscous, if the sediment loading chamber 1 is inclined, the sediment does not adhere to the inner bottom surface or the inner wall surface 4 of the sediment loading chamber 1. It is an object of the present invention to discharge the outside of the earth and sand loading chamber 1.

[0008]

According to the present invention, an opening 2 is provided at the top.
The sediment loading chamber 1 is turned over, the inner bottom surface 3 of the sediment loading chamber 1 is tilted, and the sediment 15 loaded in the sediment loading chamber 1 is passed through the opened side wall opening 6 of the side wall door plate 7 so that the sediment loading chamber 1 is opened. In the sediment loading chamber for transporting sediment to be discharged to the outside, an inner stainless steel plate 5 is stretched over the inner bottom surface 3 of the sediment loading chamber 1 and the inner wall surface 4 of the sediment loading chamber 1 to transport the sediment. It was a sediment loading room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are diagrams for explaining an embodiment of the present invention.

The earth and sand loading chamber 1 for earth and sand transportation according to this embodiment is provided on a roll-over steel car having a volume of 4,5 cubic meters and having a volume of 4,5 cubic meters, which is known before the present application and runs on rails 20 by wheels 21. It has the same configuration except for a configuration in which a loading section and an inner surface plate 5 described later are provided.

That is, the sediment loading chamber 1 has an opening 2 at its upper part, and is rolled over by a roll mechanism (not shown) with the roll axis 8 as the center of roll, as shown by a two-dot chain line in FIG. Thus, the inner bottom surface 3 of the earth and sand loading chamber 1 is formed so as to be inclined.

One side wall of the earth and sand loading chamber 1 has a side wall opening 6 formed by removing the side wall, and a side wall door plate 7 is provided in the side wall opening 6. is there. The side wall door plate 7 is mounted on both end walls 9 of the earth and sand loading chamber 1 on the side wall opening 6 side by a shaft mounting mechanism (not shown). Door plate 7
Is a door opening / closing mechanism 10, a part of which is shown in FIG. 2, and is formed so as to be opened when the earth and sand loading chamber 1 rolls over.

A stainless steel inner plate 5 having a thickness of 2 mm is stretched over the inner bottom surface 3 of the earth and sand loading chamber 1 and the inner wall surface 4 of the earth and sand loading chamber 1. The inner surface plate 5 is not extended at both ends (the end wall 9 side) of the inner bottom surface 3, and is provided at both ends of the inner wall surface 4 and at an upper portion of the inner wall surface 4. Not stretched.

Although it is possible to stretch the inner plate 5 to a position where the inner plate 5 is not stretched, an operation such as making a cut at the end of the inner plate 5 is required.
In the earth and sand loading chamber 1 for transporting earth and sand according to this embodiment, earth and sand 15 excavated at an excavation site are loaded into the earth and sand loading chamber 1 and transferred to a sediment accumulation area or the like.

Then, the sediment loading chamber 1 is turned over as shown by a two-dot chain line in FIG. 1 at a collecting place or the like, and the inner bottom surface 3 of the sediment loading chamber 1 is inclined. Then, even if the sediment 15 is a highly viscous earth and sand 15 and the earth and sand 15 is in close contact with the stainless steel inner surface plate 5, the sediment 15 is separated from the inner surface plate 5 and falls, and the sediment 15 is transferred to the sediment loading room. There is not much residue in 1.

The reason why the viscous earth and sand 15 is peeled off and dropped from the inner surface plate 5 of the loading chamber 1 of this embodiment is as follows. That is, the inner bottom surface 3 of the overturned steel wheel described in the section of the prior art.
Since the inner wall surface 4 is made of a steel plate, it is flat when viewed with the naked eye. However, when viewed microscopically, there are many irregularities. The earth and sand 15 strongly adhere to the inner surface of the steel plate.

On the other hand, the inner plate 5 of this embodiment
Is a flat surface having almost no unevenness even when viewed microscopically because it is made of stainless steel. Even if the sand 15 is highly viscous, the inner surface plate 5 has no unevenness, so that it is combined with the unevenness of the inner surface plate. The earth and sand 15
It is easy to peel off even if it is in close contact.

[0018]

According to the present invention, the inner bottom surface 3 of the earth and sand loading chamber 1 is provided.
An inner surface plate 5 made of stainless steel is stretched on an inner wall surface 4 of the earth and sand loading chamber 1.

Accordingly, the inner plate 5 has almost no microscopic unevenness on its surface, and the sediment loaded in the sediment loading chamber 1 is highly viscous sediment 15, and the sediment 15 adheres to the inner plate 5 closely. Since the inner plate 5 has no irregularities, the earth and sand 15 do not combine with the irregularities of the inner plate 5.

Therefore, even if the soil is highly viscous, the soil 15 is easily discharged from the stainless steel inner plate 5 stretched in the sediment loading chamber 1, and the soil 15 in the sediment loading 1 is discharged by tilting the soil loading chamber 1. In this case, it is possible to prevent the earth and sand 15 from remaining in the earth and sand loading chamber 1.
