Further, the motor 6, the motor 14, the deceleration motor 32, and the winding motor 35 are connected to the battery 7 as the drive source, and are each turned on and off by a switch button on the operation section 43 provided at the rear of the truck 1. can.

The functions of the above configuration will be explained one after another.

First, the work of transshipping the battery _B1 of locomotive K will be explained with reference to FIG.

The charged battery B ₁ is loaded onto the loading space S of the trolley 1 and transported to the transshipment site. On this occasion,
The lifting beam 26 has an angle determined at position D shown in FIG.
Located nearby. When the transport truck approaches the locomotive K, the deceleration motor 32 of the hoisting machine 30 for changing the angle is driven, the hoisting pole 22 is turned by hand, and the position of the hoisting pulley 27 is adjusted as shown in FIGS. 7 and 9. After raising the bogie to position A shown in the figures and FIG. In this state, the hoisting pulley 27 is located directly above the discharged battery _B1 , and the hoisting pulley 27 is located directly above the discharged battery B1.
is grounded and supported by support devices 8,8. next,
The hoisting motor 35 is driven to hoist the wire rope 3.
4, and attach the engaging claws 37 of the lifting tool 36 to the handle 3 of the discharged battery B ₁ in the storage case 40.
8 and 38, and the winding motor 35 is stopped when the bottom of the discharged battery _B1 rises above the top surface of the storage case 40. And the fixing lever 23
Loosen again and rotate the hoist pole 22 by hand.
Once the discharged battery _B1 is dropped on the ground.

Furthermore, the deceleration motor 32 is driven to lower the lifting beam 26.
Slightly raise the angle of the battery and turn it to position C, which is directly above the charged battery B ₁ in the loading space S, and drive the hoisting motor 35 in the same manner as described above to move the charged battery B ₁ . Lift it up, turn the hoist pole 22 by hand in that state, and drive the hoisting motor 35 again directly above the storage case 40 of the locomotive K, that is, directly above the loading position, to remove the charged battery. Roll down B ₁ and store case 40
Load into.

In addition, the discharged battery that has been removed is attached to the lifting burr 2.
6 is rotated in the same manner and loaded into the loading space S, the supporting devices 8, 8 are grounded and transported to the charging work station.

Next, the work of transferring the battery _B1 under the floor of the passenger car P will be explained with reference to FIG. The charged battery _B2 is loaded into the loading space S and transported to the transshipment site as described above. When the transport vehicle approaches the passenger car P, the angle of the lifting beam 26 is set at position B in FIGS. 2 is moved laterally, and the front end of the lifting beam 26, that is, the hoisting pulley 27 is thrust into the underfloor of the passenger car P.

By the way, before pushing the hoisting pulley 27 under the floor of the passenger car P, the door 42 of the battery storage box 41 is opened and the discharged battery _B2 is pulled out above the lower door portion 42a. Therefore, the engaging claw 3 of the lifting tool 36
7 and 37 are engaged with the handle 39 of the discharged battery B ₂ to drive the winding motor 35 and remove the battery B _{2 .}
Lift it until the bottom of the car P floats, then reverse the motor 14 and move the entire hoist 2 laterally in the opposite direction to pull out the discharged battery B ₂ from under the floor of the passenger car P. After that, rotate the hoist pole 22, and then Lower the discharged battery B ₂ to the ground. Next, after lifting the charged battery B ₂ in the loading space S and setting the lifting beam 26 at position B, the entire hoist 2 is moved laterally, and the charged battery B ₂ is lifted under the storage box 42 under the floor of the passenger car P. It is lowered onto the side door portion 42a. Then, the engaging claws 37, 37 are removed and the charging battery B ₂ is pushed into the back of the storage box 42. However, the removed discharged battery B ₂ is attached to the lifting beam 2 in the same manner as described above.
6 is turned and loaded into the loading space S, and the supporting devices 8, 8 are disconnected from the ground, and then transported to the charging work station.

In this way, one worker can easily and reliably transfer and transport batteries under the floor of a locomotive or passenger car. Although the above-mentioned example shows an example in which the system is used for transferring batteries of railway vehicles, it is of course possible to use the system for loading and unloading all kinds of other heavy objects.

As explained above, according to the carrier equipped with a hoist according to the present invention, one worker can load a fully charged battery onto the loading space S of the loading platform 3 and bring it to the side of the target vehicle at the vehicle depot. After that, move the hoist 2 on the loading platform 3 to one side of the loading platform 3, operate the hoist 2 to unload the battery of the target vehicle that needs charging, and charge it in the loading space S. Replace with a used battery.
Since the battery removed from the vehicle is loaded into the empty loading space S of the loading platform 3 and transported to the charging work site, it is easy to load, unload, and transport the battery, etc. to the target vehicle by one worker. Moreover, it can be done reliably and has the effect of saving labor in the above-mentioned battery transshipment work.

Further, according to the present invention, when moving the hoist 2 on the loading platform 3 of the transportation trolley 1, the guide rail 10 and the rack 1 fixed to the loading platform 3 are
7, since the wheels 12 at the bottom of the hoist base 11 and the drive pinion 16 operated by the motor 14 are engaged and moved, the movement described above is safe, easy, and efficient.

In addition, in this invention, the vertical swing of the lifting beam 26 is caused by the winding and unwinding of the rope 31 by the winding machine 30, and the lifting and lowering of the end lifting tool 36 of the rope 34 that hangs the battery is controlled by the lifting device 36 on the lifting beam 26. Hoisting machine 3
3, the winding and unwinding lengths of both ropes 31 and 34 are added together, and a relatively simple mechanism calculates the lifting length of the battery and the range of its lifting and lowering operations. This has the effect of widening the area.

Further, according to the present invention, the tip of the lifting beam 26 having the winding pulley 27 is bent upward, so that when the tip of the lifting beam 26 is lowered, The tip protrudes in a substantially horizontal direction, so that it can be easily inserted into a relatively narrow lower space of a vehicle, making it possible to easily replace the battery. (See Figure 8).
