Abstract

PURPOSE:To improve workability by collecting ballast by a screw auger provided on a self-traveling truck, sucking it by a vacuum device and conveying it to a classification system, and classifying and recovering reusable ballast. CONSTITUTION:Ballast 3 is dug up by a screw auger 4 mounted on a self- traveling vehicle 15 and conveyed and collected to the intermediate position of a rail 2. Next, the ballast 3 is sucked into a suction port 8 of a vacuum device 7 by a pitching plate 6 mounted on a rotary shaft 5 of the auger 4. Then, the ballast 3 is conveyed to a screen 11 via a pipe 10, and reusable ballast 3 is classified and recovered into a reusable ballast vehicle 12. Further, the ballast 3 which is granulated so fine as not to be reusable is conveyed from a waste ballast hopper 13 into a waste ballast truck 14 and stored in it. Thus, it is possible to simplify the structure and dig and convey ballast stably. Also, digging, conveyance, classification, and reuse can be done continuously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roadbed replacing machine for removing crushed and atomized ballast of a railroad roadbed.

[0002]

2. Description of the Related Art A conventional roadbed replacement machine is shown in FIGS.
It shows in 0. 8 is a side view before the roadbed replacement work, FIG. 9 is a plan view before and after inserting the undercutter, and FIG. 10 shows a front view after the insertion.

The details of this machine will be described with reference to the drawings. On the frame 52 which is provided in front of the truck 51, the tray 54, the rotary shaft 53 and the belt conveyor 57 are provided.
Is attached. A curved undercutter 55 is attached to the rotary shaft 53, and a chain cutter 56 composed of a plurality of blades is attached around the curved undercutter 55. Further, a motor 58 for driving the chain cutter 56 is provided above the under cutter 55.

The following is a description of the roadbed replacement work procedure by this machine. First, by rotating the motor 58, the chain cutter 56 rotates along the outer circumference of the under cutter 55. In this state, the undercutter 55 set in parallel with the rail 61 is inserted into the ballast 59 under the sleeper 60 by rotating it 1/4 of the rotation axis 53, and is orthogonal to the rail 61.

During the replacement work, the carriage 51 is moved forward, and the chain cutter 56 rotating at this time causes the sleeper 60 to move.
The lower ballast 59 is continuously excavated, and the excavated ballast 59 is scraped up onto the frame 52. The scraped ballast 51 falls into the tray 54 and is conveyed by the belt conveyor 57 into the carriage 51 at the rear. After that, classification of the ballast scraped by the subsequent equipment, supply of new ballast, compaction, etc. are performed, and the replacement work is completed.

[0006]

However, the conventional roadbed replacement machine has the following problems. (1) Since the excavation and transportation are performed by circulating the chain cutter, the construction speed is slow. (2) Initial setting of the chain cutter is troublesome. (3) Since it has a cantilever structure, it is disadvantageous in terms of strength and rigidity. (4) The chain cutter easily breaks or falls off,
It has poor durability.

[0007]

In order to solve the above-mentioned problems, the structure of the present invention is to excavate and convey finely crushed ballast in a roadbed replacement machine for removing crushed and finely crushed ballast of a railroad roadbed. A screw auger having a function to perform, a pitching plate having a function to scrape ballast attached to a rotation shaft of the screw auger, and a vacuum device for sucking and discharging the ballast.

[0008]

According to the above construction, the screw auger has a function of moving forward while excavating the ballast, and carrying and gathering the ballast to an intermediate position of the rail or an arbitrary position on the side of the sleeper by setting the lead. Then, the collected ballast is repelled by the rotation of the pitching plate to the suction port of the vacuum device, sucked from the suction port, and conveyed to the subsequent classification system.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a screw auger 4 is installed in a ballast 3 below the sleeper 1 and the rail 2, and the ballast 3 excavated by the screw auger 4 has a rotating shaft of the screw auger 4. Vacuum device 7 by a plurality of pitching plates 6 attached to
It is sucked by the vacuum pump 9 through the suction port 8 and is conveyed to the screen 11 via the pipe 10.

The screen 11 is provided with a filter (not shown) through which only the ballast 3 of a size to be discarded, which has been made finer, passes, and the reusable ballast 3 is in the reusable ballast vehicle 12. Will be collected. Further, the non-reusable ballast 3 is designed to drop from the waste ballast hopper 13 to the waste ballast vehicle 14.

The roadbed changing machine configured as described above is capable of self-propelled on the rail 2 by the trolley 15 equipped with the engine, and proceeds while excavating the ballast 3 to the left in FIG. Reference numeral 16 in FIG. 1 denotes a cabin on which an operator rides. In addition, the reusable ballast 3 is continuously discharged into the roadbed after being excavated while supplying the shortage to form a new roadbed.

FIG. 3 is a detailed view of the excavation section III-III of FIG.
FIG. 4 is a view in the direction of an arrow, and FIG. 4 is a side view of FIG. 3.

The rotary shaft 5 is supported by a carriage 15 via a ladder 17 and a bearing 18, and is rotated by a drive motor 19 on the carriage 15 via a drive chain 20 in the ladder 17 to rotate the screw auger 4 in the rotary shaft. Rotate around 5.

In the screw auger 4, the screw leads are bilaterally symmetrical, and the ballast 3 can be conveyed and gathered to the center of the track (center between rails) while excavating the ballast 3. The ballast 3 collected in the central portion is sucked into the suction port 8 by the pitching plate 6.

Further, it is possible to perform stable ballast replacement by adjusting the rotation speed of the screw auger 4 and the forward speed of the carriage 15 according to the excavation load and the amount of excavation / conveyance.

Incidentally, the screw auger 4 has a structure which can be attached and detached at the bearing 18, and at the start of the work, only the volume capable of setting the screw auger 4 is used for the ballast 3.
Initially excavated, the screw auger 4 is set by directly facing the rail 2.

5 to 7 show another embodiment of the present invention.

In FIG. 5, the lead of the screw auger 4 is unidirectional, and has a function of transporting the excavated ballast to the right in the figure. Then, the collected ballast is sucked through the suction port 8 installed on the side of the sleeper 1.

Further, the drive motor 19 is installed on the carriage 15 by a turntable 21 so as to be rotatable by 90 ° or more in a horizontal plane, and the excavating portion such as the drive motor 19, the ladder 17 and the rotary shaft 5 is mounted on the rail 2. It is possible to rotate from a parallel state to a right angle state.

6 and 7 show the situation before the start of excavation work. That is, the screw auger 4 is the rail 2
And the turntable 2 on which the drive motor 19 is placed while rotating the screw auger 4 from this state.
1 is rotated, and the screw auger 4 is directly opposed to the rail 2 while excavating the ballast. According to this method, preliminary excavation for initial installation of the screw auger 4 is unnecessary.

[0022]

As described above, according to the present invention, the following effects can be obtained. (1) Since the ballast can be excavated and transported only by rotating the screw auger, the structure is simple. (2) Stable excavation and transportation is possible by adjusting the forward speed of the bogie and the rotation speed of the screw auger. (3) A series of operations such as excavation, transportation, classification, and introduction of new ballast can be performed continuously. (4) The driving force of the trolley is exerted by the screw auger, which facilitates self-propelling.
