Then, the mounting plate 41 is attached onto the lower portion of the loading frame 6. The mounting plate 41 is formed of a flat plate material having sufficient strength, and the dimension in the vehicle width direction is slightly larger than the outer diameter of the body 91 of VCT 9 and the dimension in the vehicle length direction is substantially equal to the outer diameter of VCT 9. It has a flat rectangular shape with rounded corners. The placement plate 41 is also supported by a placement plate receiving plate 63 attached between the placement plate 41 and the coupling member 53. The VCT 9 can be placed on the mounting plate 41 with the two umbrella-shaped portions 92 directed in the vehicle width direction and the terminal box 93 directed downward.

  Both side portions 62 of the loading frame 6 continue to an upright portion 65 which rises substantially perpendicularly to the mounting plate 41 via an inclined portion 64 which rises obliquely toward the upper side. A connecting plate 66 is attached to each of the inclined portion 64 and the upright portion 65 for connecting the pipe members on both sides in the vehicle width direction. A portion extending from the upper side of the mounting plate receiving plate 63 is bent and connected obliquely upward to the lower connection plate 66.

  A battery mounting frame 67 is attached between the lower connecting plate 66 and the upper connecting plate 66, and the battery 35 is installed there. As the battery 35, a lithium ion battery having a long continuous usable time and a short charging time is employed.

The raising button 83 and the lowering button 84 are arranged symmetrically so that when the horizontal portion of the handle bar 48 is grasped with both hands, the thumbs of both hands just reach each other. The rising button 83 and the lowering button 84 are set such that the drive motor 23 moves while the vehicle 2 is traveling while only one of them is kept pressed, and stops when the user speaks a finger. The emergency stop button 85 is disposed between the raising button 83 and the lowering button 84, and is set so that the drive motor 23 is immediately stopped when it is pressed in an emergency. Furthermore, in order to prevent the emergency stop button 85 from being accidentally touched, an erroneous operation prevention guard 87 is attached to the outside thereof.

  The outrigger 7 is configured by attaching casters 72 with a brake to both legs 71 of a portal frame in which a pipe material is bent. The outrigger 7 is disposed below the lower side of the loading frame 6 so as to straddle the vehicle body 2 and is fixed to the coupling member 53 so that both leg portions 71 are orthogonal to the mounting plate 41. In order to maintain the bonding form, a reinforcing diagonal member 73 is attached between the two legs 71 and the loading frame 6.

<Operation method>
A method of operating the transport vehicle 1 configured as described above will be described with reference to FIGS. The driving operation of the transport vehicle 1 is performed by an operation box 37 attached to the center of the handlebar 48. FIG. 6 shows a traveling state on a flat surface.

  When the power is turned on on the flat surface and the mode changeover switch 82 of the operation box 37 is on the flat surface mode side, the pivot frame 5 of the gantry 4 is substantially upright with respect to the bottom surface of the vehicle body 2 (the ground surface of the track frame 21). The telescoping cylinder 34 extends in such a manner that the caster 72 of the outrigger 7 is grounded, and the bottom surface of the track frame 21 is slightly lifted. In this state, the vehicle body 2 is supported by the tandem wheel mechanism 27 on the upper side and the caster 72 of the outrigger 7, so that the transport vehicle 1 can be advanced and retracted and turned manually. In the flat surface mode, the operations of the up and down buttons 83 and 84 are invalidated.

  In the flat surface mode, since the mounting plate 41 is substantially horizontal, the brake of the caster 72 is locked in this state, and the VCT 9 is placed on the mounting plate 41. The lashing belt 47 is wound around the upper and lower two places of the VCT 9 and hooked to the hooks 45 and 46, and the buckle is fastened to fix the VCT 9 on the mounting plate 41. When it is confirmed that the VCT 9 has no looseness, the caster 72 is released from the brake, stands on the high side, moves the cart 1 up to the stairs while pushing and pulling the handle bar 48. When the vehicle body 2 is directed at right angles to the stairs and the upper side of the vehicle body 2 is abutted against the first step nose of the stairs, the mode switching switch 82 is switched to the stairs lifting mode. Then, the telescopic cylinder 34 is contracted, and the pivot frame 5 is inclined upward by a predetermined angle. Along with this, the outrigger 7 is also lifted, and the bottom surface of the vehicle body 2 is grounded. In this state, the operation of the raising button 83 and the lowering button 84 is enabled.

  FIG. 7 shows the state where the transporter 1 has started to ascend the stairs. With the vehicle body 2 in contact with the first step nose of the stairs, when the operator stands around the third step of the stairs and grips the handlebar 48 from the upper side and presses the ascent button 83, the belt crawler 25 is driven. Go up one step and stop there. In that state, the pivot frame 5 is automatically inclined to the high side.

  FIG. 8 shows the state in the middle of raising and lowering the stairs. The vehicle body 2 moves up and down while always contacting the bottom of the track frame 21 for guiding the belt crawler 25 with three or more stairs. The operator stands up on the stairs two steps higher than the vehicle body 2 and ascends and descends with the transporter 1 while holding the handle bar 48 with both hands. While continuing to press the rising button 83 at the time of rising and the lowering button 84 at the time of falling, the lifting continues, and when the finger is released from the button, it stops at the place. Since the weight of the VCT 9 is supported by the center of the vehicle body 2 in the longitudinal direction of the vehicle body 2 via the pivot frame 5, the combined center of gravity of the gantry 4 and the VCT 9 is always stable during step up and down. If the slope of the stairs is too steep from the beginning, or if the balance is unexpectedly broken during lifting and falling to the front, the lifting operation is automatically stopped by the detection of the tilt sensor 31 attached to the vehicle body 2 side .

  When shifting from the stairs to the landing or the flat surface of the upper and lower floors, the telescopic cylinder 34 is extended after the vehicle body 2 is in a safe inclination state in the reverse procedure to the above, and the pivot frame 5 is erected. The caster 72 is grounded.

  As described above, according to the transport vehicle 1 disclosed in the present application, even one worker can safely lift and lower the VCT in a stable posture. Thus, the burden on the operator engaged in the installation, repair, replacement, etc. of the power reception facility is greatly reduced, and the safety is also improved.

  The technical scope of the invention disclosed in the present application is not to be interpreted in a limited manner by the illustrated embodiment, and is to be conceptually interpreted based on the description of the scope of claims for utility model registration. is there. In the implementation of the invention disclosed in the present application, the shapes and structures of members and parts, positional relationships, bonding forms, etc. not specifically specified in the claims of the utility model registration are substantially the same as in the embodiment. In the range which is obtained, it can modify suitably and can carry out.

  Further, the transport vehicle 1 according to the invention disclosed in the present application has not only the illustrated substantially cylindrical VCT 9 but also a substantially box-like (including a rounded box-like) or barrel-like barrel similar to this. It can also be used to transport transformers, transformers and other devices and equipment.
