Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flywheel type freight car speed reduction device, and more particularly, to a flywheel type freight car speed reduction device that does not have a special power source.

The power sources for conventional freight car speed reducers include linear motor drive and rope drive, but the former requires power to be supplied to the linear motor, which requires electric wires to run along the entire length of the track. However, the latter had disadvantages in that it required a rope to be laid over the entire length of the route and required a power source to drive the rope.

SUMMARY OF THE INVENTION An object of the present invention is to provide a flywheel type freight car deceleration device that allows a freight car to decelerate and self-propel without requiring special external power.

The present invention uses a freight car deceleration device to catch freight cars that have been sorted and run at a freight car yard near the entrance of a freight car retention line called a classification line, transfer them to a position close to the retention freight car, and decelerate the freight cars until they reach a safe connection speed. After the freight car is released, the freight car speed reduction device is reversed and returns to its original position under its own power, and waits for the next operation. The energy required to decelerate a freight car during this series of operations is currently approximately 50,000 tm/day/yd, and most of this energy is absorbed and dissipated by equipment. The present invention focuses on this dissipated energy, and in order to effectively utilize this energy, a flywheel is provided to store deceleration energy and release it when the freight cars and bogies are transferred or run.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a capturing truck equipped with a freight car wheel capturing device 3 for capturing the freight car wheels 2, and is configured to capture or release the freight car by putting in and taking out rollers in front and behind the freight car wheels 2, for example. . The catching truck 1 is connected to a driving truck 5 via a connecting pin 4, and runs on a truck running rail 7 laid inside a freight car rail 6 with driving wheels 8 and running wheels 9. The driving truck 5 has a driving device 10.
is installed, and energy for driving the bogie or freight car is stored in the flywheel 23 by using the adhesive force of the drive wheels 8.

FIG. 3 shows details of the power transmission mechanism of the drive device 10. Reference numeral 11 denotes a generator motor, which connects drive wheels 8 via transmission gears 12 to 21 and a transmission shaft 22.
It is designed to drive the flywheel 2.
It is used as an auxiliary power only when the stored energy of No. 3 is low, and otherwise it is used as a generator to charge a battery for driving equipment (not shown).
Reference numeral 24 denotes a clutch, which is loosely engaged when adjusting the speed of the truck, stopping it, and energizing the flywheel. Numerals 27 and 28 are clutches for changing the running direction of the bogie, and either one is engaged depending on the running direction of the bogie. The flywheel 23 is housed in a casing 29 together with a planetary gear 25 and a drive shaft 30, and is connected to a bogie drive system via a clutch 24. In the above configuration, the operation will be explained with reference to FIG. In addition, the solid line curve in the figure shows the freight car, and the broken line curve shows the movement of the freight car speed reduction device. When a freight car approaches, the electric motor 11 accelerates the bogies 1 and 5 to near the speed of the freight car. At this time, the clutch 24 is in the "disengaged" state, and the flywheel 23 is not driven. When the freight car is captured at point B, the clutch 24 is gradually engaged and the electric motor 11 is switched to a generator. The bogies 1 and 5 are pushed by the freight car, forcing the flywheel 24 to rotate to maintain its inertial static force. In this way, deceleration is achieved by converting running energy into rotational energy. When point C is reached, the bogie acceleration energy of the flywheel 24 and the traveling energy of the freight car become equal, and the deceleration of the freight car ends. Here, trolleys 1 and 5
releases the freight car and shifts to reverse operation. When the clutch 24 is disengaged, the acceleration force of the truck disappears, and the truck stops at point D due to running resistance. clutch 2
7 and 28 are switched to the reverse side and the clutch 24 is gradually engaged, the carts 1 and 5 are reversed by the energy stored in the flywheel 24 and return to their original positions while running on their own. The flywheel 24 is installed in a chamber sealed with a casing 29, and if this chamber is kept in a vacuum state lower than atmospheric pressure, the air resistance against the rotation of the flywheel 24 can be reduced, and energy can be efficiently used. Can be accumulated.

According to the present invention, since the deceleration energy of the freight car can be stored, it is possible to control the speed of the freight car without supplying power from the outside.
