Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ballast / soil excavation for ballast removal of railroad track beds, soil trench digging, land leveling, and slope cutting for residential land development. Regarding the method.

[0002] Conventionally, a civil engineering machine device for removing ballast on the track of a railroad track, a civil engineering machine device for land preparation including rooting for building a residential land, and a step cutting of a slope (Norimen) for building a residential land. Civil engineering equipment is a separate mechanical equipment,
Although there is no device that also serves as these, the inventor of the present invention invented a multipurpose civil engineering machine device that also serves as these. Patent No. 1761635 [Japanese Patent Publication No. 4-14215 (ballast removal of the railroad track bed) For soil digging,
Multipurpose civil engineering equipment for land leveling, including root removal for leveling, and step cutting of slopes for residential land development)].

[0003]

However, the inventor of the present invention has found that the multipurpose civil engineering machine device has insufficient points for performing a predetermined work at a site having a small space such as a railway track. . The present invention aims to solve this problem.

[0004]

To achieve the above object, the present invention provides a ballast / soil digging method using an endless chain band 10, wherein the endless chain band 1 is used.
Hydraulic means (48, 49, 5) for supporting and guiding the guide board body 12 for supporting and guiding 0.
The workbench 8 having 0) is supported by a hydraulic cylinder body 9 capable of moving a portion of the guide board body 12 in contact with the ballast / soil in a horizontal direction orthogonal to the moving direction of the endless chain band 10. The worktable 8 is gradually moved in the horizontal direction according to the progress of ballast / soil digging.

Thus, as shown in FIGS. 7 and 6, the endless chain band 10 is formed by combining elliptical chain rings 24, and the required number of the elliptical chain rings 24. The oval chain ring 24 of the ballast / soil scraping protrusion 2
It is assumed that the wide plate member 26 with 5 is fixed, and that the scraping protrusion 25 is a cone-shaped protrusion 2 that is diagonally upward.
5a and the oblique downward pyramidal projection 25c are sequentially fixed, the oblique upward pyramidal projection 25
It is preferable that a horizontal conical protrusion 25b is provided at an intermediate position between a and the downward conical protrusion 25c.

The moving speed of the endless chain band 10 is preferably in the range of about 3 to 5 US / sec.

[0007]

The method of the present invention is applied to the multipurpose civil engineering machine apparatus 1 shown in, for example, FIG. 1 (side view of the whole multipurpose civil engineering machine apparatus), FIG. 2 (front view of the same) and FIG. 3 (plan view of the same). And a tip end portion 15 of an inverted V-shaped guide plate band 12 (in the illustrated example) having a chain band guide groove 11 for supporting and guiding the endless chain band 10 provided with ballast / soil digging means
Is brought into contact with a place to be dug out, for example, a place on the side of the ballast layer 14 below the sleepers 13 of the railway, and the guide board body 1 is brought to the place to be dug out by operating the hydraulic cylinder body 9.
2 is moved gradually and at the same time endless chain belt 10
Is operated at a high speed of about 2 US / sec or more to scrape out ballast and soil.

At this time, the portion of the guide board 12 that projects into the ballast layer 14 is the horizontal portion 16 of the guide board 12, and the ballast scraped out is located at a side of the machine body 2 which is far away from the ground. It is discharged from the guide board body 12 at the scraped-out material discharging portion 17 located at, is moved to a desired place by the belt conveyors 3, 4, and, and is collected on, for example, a truck bed. For this purpose, the upper end 52 of the guide board 12 is
A cover body 18 is attached to collect the emission so as to cover the vicinity. (See FIGS. 5, 1 and 3).

In the method of the present invention, the moving speed of the endless chain belt 10 for digging and scraping ballast / soil is set to a high speed of about 2 US / sec or more, because it is sufficient for the digging at a low speed. This is because the present inventor has found that scraping is difficult. Further, it is most preferable to set the moving speed in the range of about 3 to 5 US / sec. If the speed is higher than this, the wear of the member for scraping out the endless chain band 10 is accelerated, which is not preferable.

The moving speed of the endless chain band 10 is about 2 US / sec or more during the work.

In the multipurpose earthmoving apparatus for carrying out the method of the present invention, in order to smoothly carry out the above-mentioned work, the guide board 12 having an inverted V-shape is supported and can be moved vertically and horizontally. The workbench 8 having the hydraulic means (48, 49, 50) can move the portion of the guide board 12 that comes into contact with the ballast / soil in the horizontal direction orthogonal to the moving direction of the endless chain band 10. It is supported by a hydraulic cylinder body 9 and gradually moves the workbench 8 in the horizontal direction in accordance with the progress of ballast and soil excavation.

As shown in FIGS. 6 and 7, in the multipurpose earthmoving apparatus for carrying out the method of the present invention, the endless chain band 10 is formed by combining elliptic chain rings 24, 24, 24. None, the required number of elliptical chain rings 24 among the elliptical chain rings are those to which the wide plate 26 with the ballast / soil scraping projection 25 is fixed. The body 26 includes an obliquely upward conical projection 25a, a horizontal conical projection 25b, and an oblique downward conical projection 25.
Due to the structure in which c is sequentially fixed, the digging can be performed efficiently.
