Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a bogie transfer facility used when exchanging or inspecting a vehicle body and a bogie and performing maintenance work.

[Conventional technology]

The state where the vehicles remain connected, that is, the work of taking out the bogie of the vehicle from the vehicle body without disconnecting the formation state and inspecting, maintaining or exchanging the bogie does not require the work of disconnecting the vehicles and reconnecting after the work. It is advantageous in terms.

As a method of taking out the bogie from the vehicle body, a method of hoisting the vehicle body and moving it to another place and leaving only the bogie on the spot, or a method of hoisting the vehicle body and taking out only the bogie sideways is known. However, it is extremely difficult to apply these methods to a vehicle in a knitted state for several hundred meters because the knitted state must be lifted or lifted. Further, even when applied to each vehicle, the hoisting or hoisting height of the vehicle body is at most within the vertical allowable range of the coupler, and it is not possible to dodge the vehicle body and take out the bogie sideways. Therefore, according to the above-mentioned method, the formation of the vehicle must be performed in a state where the formation of the vehicle is separated for each vehicle, which is a troublesome work.

Therefore, recently, the lifting stroke of the vehicle body is limited to the allowable range of the coupler, or the vehicle body is supported at the current position or at a position slightly above the current position, and the vehicle is lowered to the required vertical space when the vehicle is taken out from the vehicle body. It is known how to get by. The method is embodied as the conventional bogie transfer device described below.

The conventional bogie transfer device is of a self-propelled type, and its operation will be described with reference to FIGS. 1 to 4. FIG. 1 shows a state in which the vehicle body 1 is on the trolley support device 2. After supporting the vehicle body 1 by the vehicle body supporting device 4, the trolley supporting device 2 is lowered as shown in FIG. 2 to separate the trolley 3 from the vehicle body 1. The trolley support device 2 that has moved down is moved in the underground pit by the traveling device 5 to the side line rail side next to the main line rail.
The moving state is shown in FIG. FIG. 4 shows a state in which the carriage 3 is being raised to the level of the side rail. In this state, the carriage 3 separated from the vehicle body 1 and brought to the side line is inspected, and if there is an abnormality in the carriage of the vehicle, a new carriage is mounted on the carriage transfer device. The new trolley is attached to the vehicle body 1 in the reverse order of the above-mentioned separating operation.

[Problems to be solved by the invention]

Since the trolley support device 2 used in the conventional trolley transfer device lowers the trolley 3 separated from the vehicle body and moves it to the side rail side, the trolley 3 must be completely moved into the underground pit. Therefore, it is necessary to dig deep into the pit, and also to dig a passage pit for movement that connects the main line and the side line, and it is also necessary to lay an underground rail for the moving device 5, resulting in a large and complicated pit. It was Further, since the pits must be dug in the main line and the side lines, the pit on the side where the carriage supporting device 2 is not present has a hole on the ground surface, which is a safety problem.

An object of the present invention is to obtain a bogie transfer facility that can simplify the installation pit shape.

[Means for solving problems]

The purpose is to provide a vehicle body support facility for supporting the vehicle body of the main rail, a truck support rail linearly connected to the main rail, and a side portion of the truck support rail at a position lower than the main rail. Substantially at the height of the floor, a side rail that is arranged at an angle to the direction of the main rail, and a lifting device that raises and lowers the carriage supporting rail between the main rail and the side rail, A first rotating device mounted on the elevating device for rotating the carriage supporting rail between the main line rail and the side line rail, and the first rotating device and the elevating device being installed. And a second rotating device that substantially supports the pit and that is supported by the pit and that rotates by the rotation of the rotating device. Can be achieved. .

[Work]

When the trolley of the vehicle that has entered the vehicle by traveling on the main line rail is placed on the trolley support rail, the trolley of the trolley stops traveling, the body is supported by the body support device in this state, and then the lifting device is operated to support the trolley. The trolley is lowered to remove the dolly from the vehicle body, and then the trolley-supporting rail is rotated by the first rotating device to match the side rail, and in this state, the trolley is pulled out to the side rail.

According to this, since it is not necessary to squeeze the carriage into the pit, not only the pit shape is small and simple, but also the number of pits opening in the foundation can be reduced by half and the cost can be reduced.

Moreover, the amount of lifting of the lifting device can be reduced, and the cost can be reduced.

In addition, since the pit is covered with the second rotating device, it can be safely performed. Since the second rotating device is supported by the pit and is not supported by the first rotating device and the elevating device, the second rotating device does not move up and down by the elevating device, so that the pit can be always covered. Since the second rotating device is rotated by the first rotating device, the carriage can be rotated.

Further, because of the above configuration, the pit can be covered at all times.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 5 to 11.

As shown in FIG. 5, a vehicle body 8 of a railway vehicle is constructed by housing a bogie 10 in a lower skirt of the vehicle body 8. This vehicle can be driven on the main rail 7 by the carriage 10. The main line rail 7 is installed at a position higher than the side line rail 20 for pulling out the carriage 10 as shown in FIG. 8, and is installed in an arrangement perpendicular to each other as shown in FIG.

A carriage transfer device is provided in the middle of the main rail 7 as shown in FIG. The main part of the trolley transfer device includes equipment in a pit provided on the foundation and a vehicle body support device 9 provided on the upper surface of the foundation. The vehicle body support device 9 includes a gate-shaped frame 9a that is erected on both sides of the main rail 7, a frame 9b that is vertically attached to the gate-shaped frame 9a, and a frame 9b that is horizontal toward the vehicle body 8. A claw 9c that can be freely moved back and forth and a cylinder device 9d that horizontally drives the claw 9c.
And a lifting drive device that lifts and lowers the frame 9b that can be lifted and lowered.
It consists of 9e. The lifting drive device 9e is a motor 9f shown in FIG.
The ohmic gear 9g shown in FIG. 5 is the ohmic gear shown in FIG.
A screw feed device for rotating a gear 9i screwed to a screw shaft 9h via 9g is employed in the up-down direction to apply a lifting force to the frame 9b. In order to lift the vehicle body 8 horizontally, at least another pair of vehicle body support devices 9 is provided near the other end of the carriage.

On the bottom of the pit 16 dug in the foundation, as shown in Fig. 7,
A table lifter 13 of a type in which a cross link mechanism is driven by a cylinder device 19 is installed. The turntable 12 is rotatably supported on the table lifter 13. The turntable 12 is rotationally controlled by engaging a small gear 12b with a fire gear 12a attached to the turntable 12 and rotating the small gear 12b with a motor 12c attached to a table lifter 13. These form the first rotating device.

As shown in FIGS. 5 and 6, an auxiliary turntable 14 is arranged above the turntable 12 so as to close the pit 16. The auxiliary turntable 14 is rotatably and independently supported by a guide roller 14b on a circular track 14a supported from a side wall in the pit. The track 14a and the guide roller 14b form a first rotating device. The auxiliary turntable 14 is provided with slits 14c and 14d opened in the vertical direction. The rail support 11 having the slits 14c and 14d attached to the turntable 12 penetrates therethrough. In particular, a carriage stopper device 15 attached to the turntable 12 is penetrated through the slit 14d. A rail 6 for supporting the carriage is provided above the rail support 11, and as shown in FIG.
It is installed as a series of arrangement so that it becomes a part of.

The trolley stopper device 15 holds a stop position of the trolley 10, that is, a stop position of the vehicle, by sandwiching a part of the trolley 10 from the forward and backward directions by a stopper lever.

As shown in FIG. 7, the carriage support base 11 is a rail frame lock device.
17 can be engaged. This rail frame lock device 17
Is installed on the upper surface of the foundation, and horizontally moves the claw 17b forward and backward by the cylinder device 17a. The claw 17b that has advanced to the rail support 11 side moves the rail support 11 from the rail 6 for supporting the bogie to the rail 7 for the main line. Support in a state of matching the height. Then, when the table lifter 13 is operated, the claw 17b can be moved in a direction away from the rail support 11 so as to prevent the vertical movement of the rail support 11 from being damaged.

The bogie transfer operation in this embodiment having such a configuration is as follows.

A vehicle in the formation state is allowed to enter the main line rail 7 and is stopped when the trolley 10 of the vehicle for the purpose of work comes on the trolley support rail 16 in the formation. In this case, as shown in FIG. 7, the rail support 11 is previously supported by the rail frame locking device 17 so as not to cause a step on the carriage supporting rail 16 with respect to the main rail 7, and the main rail 7 and the carriage. Achieves smooth transfer between the supporting rails 16. Also,
The rail support device 11 is supported by a rail frame lock device 17 so that the rail frame lock device 17 does not naturally fall under the load of the vehicle.

Next, the stopper lever of the carriage stopper device 15 is raised and applied to the carriage 10, and the stop position of the carriage 10 is finely adjusted and held at the specified position.

Next, the claw 9c of the vehicle body support device 9 is advanced to the positioned vehicle 8, and the claw 9c is positioned at the support position of the vehicle body 8. Then, the lifting drive device 9e slightly raises the pawl 9c to apply the load of the vehicle body 8 to the pawl 9c. The claw 9c only supports the load of the vehicle body 8 and does not require a large lifting stroke. For this reason, the claw 9c should be within the upper and lower allowable range of the coupler.
Is enough to rise.

In this state, the carriage 10 is in the skirt portion of the vehicle body 8 and cannot be pulled out to the side, as shown in FIG.

Here, the claw 17b of the rail frame lock device 17 is attached to the rail support 1
Set back from 1.

Next, the cylinder lifter 19 shown in FIG. 7 is contracted to lower the table lifter 13 from the raised position shown in FIGS. 5 and 7 to the lowered position shown in FIGS. 8 and 9. When the table lifter 13 is in the lowered position, the carriage stopper device 15 and the rail support 11 supported by the table lifter 13 via the turntable 12 also descend. Therefore, the carriage supporting rail 6 on the rail support 11 has the same height as the carriage 10 supporting only the carriage 10 as shown in FIG. The auxiliary turntable 14, which is not supported by the table lifter 13, continues to be supported by the foundation via the circular track 14a at the same height as the upper surface of the foundation. Therefore, the auxiliary turntable 14 keeps the pits closed to prevent a fall accident or the like of a peripheral worker.

Next, when the carriage 10 is located below the skirt of the vehicle body 8, that is, when the table lifter 13 reaches the lowered position, the turntable 12 is rotated by driving the motor 12c, and the turntable 12 is rotated. The rotation position of the truck supporting rail 6 is changed by 90 degrees from the state shown in the figure to the state shown in FIGS. While the turntable 12 is rotating, the rail support 11 hooks the auxiliary turntable 14 at the slits 14c and 14d to rotate it in the same direction as the turntable 12. The auxiliary turntable 14 still covers the pit.

As shown in FIG. 10, when the turntables 12 and 14 are rotated 90 degrees, the bogie supporting rail 6 is a side rail.
There will be a series of 20 arrangements. Here, the trolley stopper device
Tilt the stopper lever 15 and release it from the trolley 10. afterwards,
The carriage 10 is pulled in from the carriage supporting rail 6 to the side rail 20 side to be transferred.

The bogie 10 transferred to the side rail 20 is on the spot.
Alternatively, the inspection / maintenance work is performed at a place carried along the side rail 20. Then, the dolly after the work is attached to the vehicle body 8 by a means reverse to the conventional one. When it is necessary to replace with a new trolley, the new trolley is mounted on the side rail 20 in place of the old trolley, and this new trolley is attached to the vehicle body 8 in the reverse order of the conventional procedure.

After the dolly 10 is attached to the vehicle body 8, the dolly that has been attached is made to travel from the dolly supporting rail 6 to the main line rail 7 side, and the operation for the next dolly is started. After the work for one vehicle, the bogie portion of the next one vehicle in the connected state is transferred to the bogie supporting rail 6. After that, the bogie transfer work is performed in the same procedure as described above. Such a work is repeated with the trolley parts placed on the trolley supporting rails 6 one by one in the knitted state, and the work is performed in the knitted state for each vehicle.

In the above embodiment, the push-up type in which the cross link and the cylinder device 19 are combined with the table lifter 13 is used, but other lift-up type lifters or lifting type may be used. Further, the table lifter 13 may be arranged below the turntable 12 or between the turntable 12 and the rail support 11. Further, the vehicle body support device 9 is going to rise to receive the vehicle body 8 by raising the pawl 9c, but due to the lowering of the vehicle body 8 that occurs when the table lifter 13 is lowered without the raising function, the vehicle body support device 9 is moved to the pawl 9c. You may adopt the method of sharing the vehicle body. This vehicle body support device 9 is also the vehicle body 8
It suffices to support, so it does not matter whether it is received and supported from below or hung by a crane or the like. However, in consideration of the knitting state, the support height of the vehicle body 8 must be within the allowable vertical height range of the coupler with respect to the front and rear vehicles. Further, it is naturally possible to use it even for a vehicle that is not in the formation state.

According to the present invention, since it is not necessary to let the bogie into the pit, the pit shape is not only small and simple, but also the number of pits that open to the foundation can be reduced by half, and the lifting amount of the lifting device can be reduced, It can be made cheap. In addition, since the pit is always covered with the second rotating device, it can be made safe.
