The wheel drive mechanism of the right system is composed of a right bearing box 4, It is comprised from the right drive wheel 7, the drive shaft 8, and the AC motor 10 with a gear. Therefore, even when one of the wheel drive mechanisms breaks down or a failure occurs in a component, the work of pulling the motor carriage removed from the Shinkansen vehicle using the other wheel drive mechanism and transporting it to the truck inspection site Can be done without interruption.

  In addition, since the self-propelled carriage mobile device 1 is stuck due to a failure under the lifted Shinkansen vehicle, it is no longer necessary to perform the removal work under the lifted Shinkansen vehicle. Can be secured. Furthermore, since only the part on the side where the failure or malfunction occurs needs to be replaced or repaired, the parts replacement work and repair work can be easily performed, and the maintenance cost can be kept low.

  Next, a pair of left bearing boxes 11 and a pair of right bearing boxes 12 are also attached to the lower surfaces of the rear portions of the left frame 2a and the right frame 2b of the body frame 2, respectively. The left bearing box 11 supports the axle 14 of the left driven wheel 13 (iron wheel) in a rotatable state, and the right bearing box 12 supports the axle 16 of the right driven wheel 15 (iron wheel) in a rotatable state. .

  On the other hand, as can be seen from FIG. 1, the vehicle body frame 2 is equipped with two battery power sources 21 to be used as drive power sources for the two wheel drive mechanisms at the rear part thereof. The two battery power sources 21 include a battery unit 22 used as a driving power source for the left-side geared AC motor 9 and a battery unit 23 used as a driving power source for the right-side geared AC motor 10. Each of the battery units 22 and 23 is a 48V drive power source in which a plurality of general-purpose 12V lead batteries are connected in series, four in this example. A lithium ion battery or the like can be used instead of the lead battery.

  In this example, in addition to the two battery power sources 21 for driving, one system of control battery power source 24 is mounted. The control battery power source 24 is composed of two general-purpose 12V batteries. Further, three chargers 25, 26, 27 for charging the battery units of the respective systems are mounted on the left end of the battery power source 21 in the vehicle body frame 2.

  As shown in FIG. 1 and FIG. 2B, two multiple boosters 31 and 32 for boosting the battery power are mounted on the front portion of the battery power source 21 in the vehicle body frame 2 as shown in FIGS. On the left side of these, a battery level indicator 33a and a charger cord reel 33b for displaying the battery level of each system are mounted.

Next, an operation panel 34 and a driver's seat 35 are arranged on the right side of the battery power source 21 in the body frame 2. A control panel 36 that controls each part is mounted on the rear side of the driver seat 35, that is, on the right side of the battery power source 21. Further, as shown in FIGS. 1 and 2 (a), a rotating lamp 37a and an emergency stop button 38a are arranged at a position on the front end side of the right frame 2b of the body frame 2. Similarly, a rotating lamp 37b and an emergency stop button 38b are disposed at the rear end portion of the left frame 2a of the frame, as shown in FIGS. Further, as shown in FIGS. 1 and 2A, a signal lamp 39 that can be switched between red and green is attached to the front end portion of the left frame 2a.

  Next, FIG. 3 is a front view, a side view, and a bottom view showing a portion of the left drive wheel 5. It is desirable to be able to easily perform the work of removing the parts from the vehicle body frame 2 at the time of failure, maintenance inspection or the like. For this purpose, the pair of left bearing boxes 3 that support the drive shaft 6 of the left drive wheel 5 in a rotatable state use front and rear fastening bolts 41 and nuts 42 with respect to the vehicle body frame 2. And is detachably attached. The shaft end inside the drive shaft 6 is connected and fixed coaxially to the output shaft 9b in the gear box 9a on the geared AC motor 9 side. The gear box 9a is detachably connected to the vehicle body frame 2 side via a mounting bracket 9c by bolts and nuts. Therefore, the unit including the left drive wheel 5, the drive shaft 6, the left bearing box 3, and the geared AC motor 9 can be easily detached from the vehicle body frame 2. The side of the right drive wheel 7 is also configured in the same manner, and its removal is easy.

  As can be seen from the front view and side view shown in FIG. 4, the pair of left bearing boxes 11 of the left driven wheel 13 is also attached to the vehicle body frame 2 in a detachable state by two front and rear bolts and nuts 11a and 11b. ing. The portion of the right driven wheel 15 is similarly configured. Thus, it is convenient because the left and right drive wheels 5 and 7 and the left and right driven wheels 13 and 15 can be easily detached and attached. Further, the number of parts to be removed at the time of parts replacement can be reduced, parts replacement work can be performed efficiently, and costs can be kept low.

  Next, FIG. 5 is a schematic block diagram showing a control system of the self-propelled cart mobile device 1. As shown in this figure, two drive power sources and a drive control system for driving the left and right wheel drive mechanisms are provided. In other words, the battery units 22 and 23 are provided as drive power sources for driving the left and right wheel drive mechanisms, and the supply control of two systems of 48 V DC current output therefrom is a control circuit of the control panel 36. This is performed by power supply control switches 36b and 36c that are controlled to be switched by 36a.

  In the drive control system on the left side, a direct current of 48V is supplied to the multiple booster 31 via the switch 36b of the control panel 36 and boosted to 288V, which is the drive voltage of the geared AC motor 10. As the multiple booster 31, for example, a multiple booster DC-DC boost converter manufactured by Nipron Corporation can be used. The boosted direct current is converted into an alternating current through a DC-AC converter, for example, a silicon rectifier 51, and then supplied to the motor driver 52. The motor driver 52 drives the geared AC motor 9 under the control of the control panel 36. The left drive wheel 5 is rotationally driven by the geared AC motor 9.

  Similarly, the drive power source for driving the right wheel drive mechanism includes a battery unit 23 of the battery power source 21, and the control panel 36 performs supply control of a 48 V DC current output therefrom. In the right drive control system, 48V DC current is supplied to the multiple booster 32 via the switch 36c of the control panel 36, and is boosted to 288V which is the drive voltage of the geared AC motor 10. The boosted direct current is converted into an alternating current through a DC-AC converter, for example, a silicon rectifier 53, and then supplied to the motor driver 54. The motor driver 54 drives the geared AC motor 10 under the control of the control panel 36. The right drive wheel 7 is rotationally driven by the geared AC motor 10.

  Thus, in this example, the battery units 22 and 23 having a configuration in which 12V general-purpose batteries are connected in series are used as the drive power source, and the booster 31 and 32 boosts this to the motor drive power. By using a general-purpose 12V battery, the manufacturing cost of the self-propelled cart mobile device 1 can be reduced, and maintenance of the battery power source 21 and battery replacement can be performed at low cost.

  In addition, since the battery voltage is increased to the voltage required as the driving power of the AC motor using the multiple boosters 31 and 32, the number of 12V batteries connected in series can be reduced. Therefore, since the number of parts at the time of battery replacement is small, the battery replacement cost can be kept low. In addition, since the battery installation space is small, it is advantageous in reducing the size and cost of the self-propelled cart mobile device 1.

  Further, since the two drive power sources and the drive control system are provided, the self-propelled cart mobile device 1 can be moved using a normal system even when a failure or malfunction occurs in one of the systems. Therefore, when the self-propelled carriage mobile device 1 is stuck under the lifted Shinkansen vehicle, it is not necessary for the worker to perform recovery work in a dangerous state. In addition, since only the part on the side where the failure or malfunction occurs needs to be replaced, the part replacement work is easy and the maintenance cost can be kept low.

  Here, in order to perform the towing operation of the motor carriage safely, it is desirable to include a remote controller 55 for remote control in addition to the operation panel 34 mounted on the body frame 2. In this case, the control panel 36 performs rotational drive control of the left driving wheel 5 and the right driving wheel 7 based on the steering command from the operation panel 34 and the remote controller 55.

  In this case, the motor cart can be pulled as follows. First, as shown in FIG. 1, motor carriages 60 (1), 60 (2)... Removed from the body (not shown) of a lifted Shinkansen vehicle are connected to each other by a connecting member 61 and the top. The motor cart 60 (1) is connected to the self-propelled cart mobile device 1 by the connecting material 62.

  Thereafter, the self-propelled carriage mobile device 1 is moved to a position off the bottom of the body of the Shinkansen vehicle that has been lifted up by remote control by the remote controller 55 (see FIG. 5). In this way, it is not necessary for the operator to move the motor carts 60 (1), 60 (2), etc. by maneuvering the self-propelled cart mobile machine 1 under the lifted vehicle body. So it is safe. Next, after the self-propelled cart mobile machine 1 and the motor carts 60 (1), 60 (2),... Have moved to the position deviated from the bottom of the vehicle body, as shown in FIG. When P sits in the driver's seat 35 of the self-propelled cart mobile device 1 and operates the operation panel 34, the self-propelled cart mobile device 1 is steered more smoothly and safely than in the case of remote control. It can be pulled to the training ground.
