Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a scraper device installed on a conveyor in a conveyor car in which the conveyor is installed on an open freight car used for transporting railroad bed ballast.

[Conventional technology]

When railway track bed ballast is used for a long period of time, problems such as increased soil contamination and poor drainage occur, so we use a track bed replacement device to sift out old track bed ballast, and remove soil that is heavily contaminated with soil and sand. It is necessary to dispose of this ballast and replace it with new ballast.

In this case, in a double-track section, wagons for transporting waste ballast are lined up on one track, and waste ballast collected by work vehicles on the other track is dumped into the wagons on the side.

[Problem that the invention attempts to solve]

The above method can only be used on double-track sections, and on single-track sections, waste ballast must be manually loaded onto freight cars, which poses the problem of extremely inefficiency.

Furthermore, even in double-track sections, using the left and right tracks as described above has the problem of blocking both the up and down tracks, making it impossible for trains to pass.

[Means for solving problems]

In order to solve the above problems, this invention attaches the scraper to a scraper frame that moves along the conveyor frame so that it can move up and down, and locks a piece provided on a part of the scraper in the raised position to raise the scraper. The scraper frame is provided with a locking frame having a pin hole into which a pin for preventing descent is removably inserted, and both ends of the scraper frame are fixed at the front and rear of the scraper frame to form an endless chain. The sprocket is attached to a sprocket attached to the conveyor frame so that the sprocket rotates as the scraper moves, and a part of the conveyor frame is connected to and disengages a ratchet wheel that rotates in conjunction with one of the sprockets mentioned above. It is equipped with a claw that can be rotated or stopped freely, and a handle for operating the claw.

[Effect]

This invention has the above-mentioned configuration, and when waste ballast on a conveyor is passed through without being thrown into a freight car, the scraper is placed in the raised position, that is, the inactive position, so that the scraper does not work, and the conveyor car connected to the rear The waste ballast and the like transported from the conveyor are transported as they are by the conveyor, and serve as a relay conveyor to be sent to the conveyor connected to the front.

In addition, when loading waste ballast etc. on the lower open freight car, lower the scraper to the working position at the rear of the freight car, lock the pawl to the ratchet wheel using the operating handle of the scraper fixing means, and then attach the sprocket together with the ratchet wheel. When the scraper is fixed by stopping, the ballast on the belt is distributed to the left and right by the scraper and discharged from the conveyor into the lower freight car. After loading waste ballast etc. into the rear of the freight car, if you set the scraper free, the scraper will be pushed by the waste ballast etc. on the conveyor and move, so when the scraper reaches the next position, fix the scraper again. Ballast etc. can then be discharged to that area.

After discarded ballast and other materials have been loaded uniformly over the entire length of the freight car, the scraper is raised and the piece attached to a portion of the scraper is engaged with a pin fitted into a pin hole in a locking frame provided in the scraper frame. By stopping the scraper and preventing it from descending, the scraper is placed in an inactive position, and the next delivered waste ballast passes over this freight car and heads onto the next freight car.

As shown in the figure. That is, the scraper main body 12 has a V-shaped planar shape with a pointed rear end, and its pair of left and right arms 13 are fixed to a horizontal shaft 15 above the front part of the scraper frame 14.

As shown in FIG. 4, the scraper frame 14 has an upward U-shape with a high front part, and a pair of left and right sides are arranged on both sides of the belt 7, and are connected together by a pair of front and rear connecting rods 16, 17 passing under the carrier side of the belt 7. It is fixed at .

Further, groove wheels 18 are rotatably attached to the front and rear lower portions of the left and right scraper frames 14, respectively, and these groove wheels 18 are placed on guide rails 21 on both sides of the conveyor frame 3.

22 in FIGS. 3 and 4 is the scraper frame 14.
This connecting rod 22 connects the front upper end of the
The horizontal shaft 15 is rotatably fitted into left and right bearing tubes 23 fixed to the rear part of the scraper frame 14, and both ends of the horizontal shaft 15 pass through the bearing tube 23 and protrude outside the scraper frame 14, as shown in FIGS. As shown in the figure, it bends forward and becomes the operating lever 24 of the scraper operating means 20.

Reference numeral 25 in FIGS. 3 and 4 is a locking frame fixed above the rear outer surface of the scraper frame 14, and has a pin hole 26 therein.

Pieces 27 are provided at both ends of the horizontal shaft 15, and the belt 2
4 downward to raise the scraper body 12, the piece 27 enters the locking frame 25 and the pin hole 2
The main body 12 is held in an inactive position by a pin 28 which is removably fitted into the main body 12.

Further, a rubber plate 30 is attached to the lower edge of the scraper body 12 along its entire length as shown in FIG. 4 to prevent the belt 7 from being damaged when the scraper body 12 is placed on the conveyor belt 7. Also,
Chutes 31 are attached to both outer sides of the scraper frame 14 as shown in FIGS. 1 and 2, respectively.

32 and 33 in FIGS. 1 and 2 are sprockets attached to the front and rear of both sides of the conveyor frame 3,
The front and rear folded portions of a chain 35, which is made endless by connecting the front and rear ends of the left and right scraper frames 14, are connected to each sprocket 32, 33, so that when the scraper 11 moves, the sprockets 32, 33 rotate. .

38 in FIG. 2 is a scraper fixing means, the details of which are shown in FIG. 5. In FIG. 5, reference numeral 39 denotes a support frame fixed to the outside of the conveyor frame 3 behind the sprocket 33.

Now, when the handle 41 is facing downward as shown in FIGS. 2 and 5, the pawl 42 engages with the ratchet wheel 43 and prevents the ratchet wheel 43 from rotating clockwise. Therefore, since the sprocket 33 which is interlocked with the ratchet wheel 43 cannot rotate clockwise, the belt 7 is driven by the pulley in the direction of the arrow in FIGS. When the ballasts and the like are transported, they hit the scraper main body 12 at the lower working position and are discharged into the open freight car 1 from both sides of the scraper 11 while it is stopped.

After a suitable amount of ballast etc. has been discharged to a certain position on the open freight car 1 in this way, the handle 41 is turned to the left in FIG. The scraper 11 is moved forward by being pushed by a ballast, etc., and when the handle 41 is returned to its original position when the scraper 11 is moved to an appropriate position, the scraper 11 stops again.

By repeating the above operation, scraper 1
1 uniformly loads waste ballast etc. into the freight car 1 while moving intermittently at appropriate pitches.

Also, the operation lever 24 of the scraper 11 is moved to the fourth position.
The piece 27 is locked by turning it downward as shown by the chain line in the figure, inserting the piece 27 into the locking frame 25 as shown by the chain line in Figure 4, and fitting the pin 28 into the pin hole 26.
The scraper 11 is fixed in an inactive position.

In this state, there is a gap between the scraper body 12 and the belt 7, and the ballast of the belt 7 passes through the lower part of the scraper body 12 as it is.

〔effect〕

As mentioned above, this idea is to attach a scraper vertically to a scraper frame that moves along a conveyor frame, and a pin that locks a piece provided on a part of the scraper in the raised position to prevent the scraper from descending. Since the scraper frame is provided with a locking frame having a pin hole into which the scraper is detachably inserted, when the scraper is placed in the non-working position, the scraper is raised to the non-working position and the piece is inserted into the locking frame. If you place the pin above the pin hole and insert it into the pin hole, the piece will be received by the pin and the scraper will be prevented from descending.When the pin is removed, the scraper will descend under its own weight and return to its working position. Since it returns, it is extremely easy to set the vertical position of the scraper.

In addition, the front and rear folded parts of an endless chain with both ends fixed at the front and rear of the scraper frame are connected to sprockets installed at the front and rear of the conveyor frame so that the sprocket rotates as the scraper moves, and a part of the conveyor frame for,
Since the scraper fixing means is provided, which consists of a pawl that engages and disengages from the ratchet wheel that rotates in conjunction with any of the sprockets, and allows the ratchet wheel to rotate or stop together with the sprocket, and a handle for operating the pawl, the scraper fixing means can be easily operated. The scraper can be fixed in a predetermined position by engaging the pawl with the ratchet wheel using the handle, and when the pawl is removed from the ratchet wheel using the operating handle, the scraper can move freely. Therefore, it can be easily switched to both a loading conveyor and a relay conveyor. As mentioned above, this design allows work to be carried out on a single track, so waste ballast and the like can be loaded efficiently even on single track sections, and work can be carried out on return tracks while trains pass through one track.
