DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-floor electric bogie that carries a heavy object such as a container used at a construction site and travels.

[0002]

2. Description of the Related Art A container loaded with construction materials has wheels, and is moved while being pushed by an operator, or is moved by scooping up with a forklift.

[0003]

In the working mode in which the worker moves the container or moves it with a forklift, the worker requires heavy labor and requires a large work space. In order to move the container by power, a low-floor electric bogie that moves into the bottom of the container by lifting the container has been considered. This low-floor electric bogie is provided with a control box provided with a control switch and the like. However, this control box is relatively weak, and is easily damaged by building materials and the like. In addition, in this low-floor electric bogie, the loading platform must be provided at a position as low as possible in order to enter under the container. Therefore, an object of the present invention is to provide a low-floor electric bogie in which a control box is hardly damaged and a bed is as low as possible.

[0004]

According to the present invention, a traveling device 1 is provided.
In a low-floor electric bogie having a control box 4 provided with a start switch 3 and the like at one end of a bogie frame 2 provided with a lift and a lift 5 provided at the other end thereof, when the load 5 rises, the load 5 Moved up to cover.

[0005]

In this electric bogie, the control box 4 and the loading platform 5 are provided side by side on the chassis frame 2 so that the overall height is made as low as possible. Since the loading platform 5 moves and ascends so as to cover the control box 4, it is possible to prevent the control box 4 from being easily damaged by construction materials and the like. In addition, by providing a hole 6 in the loading platform 5 and positioning the hole 6 on the suspension hook 7 provided in the chassis frame 2 when the loading platform 5 is lowered, the hook 7 is hung with a rope and suspended, so that the electric bogie can be suspended. Moving can be performed stably.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 3, the chassis frame 2 includes a box frame 10 that is long in the front-rear direction.
1 and 12, and track frames 13 and 14 are connected to the left and right outer sides of the horizontal rails 11 and 12, respectively.
The horizontal crosspieces 11 and 12 are connected to each other at the center of the left and right sides to form a central crosspiece 15.
6 is attached. Three batteries B are respectively mounted on the left and right inner portions of the frame frame 10 with a center bar 15 interposed therebetween. The board 18 is mounted. Lift arms 19, are provided between the left and right outer sides of the frame 10 and the track frames 13, 14.
20 pivots.

A traveling device 1 is constructed by winding a crawler belt 23 around a tension roller 21 provided at all ends and a sprocket 22 provided at a rear end of the track frames 13 and 14.
Is composed. The sprocket 22 has an electric motor M
Is mounted to drive and run with the electric power of the battery B. FIG. 4 shows a connection structure between the lifting frame 25 provided on the chassis frame 2 and the chassis frame 2, and the auxiliary arms 26, 27 having a U-shaped cross section project downward from the left and right sides of the lifting frame 25. This auxiliary arm 2
Lift arm 1 at the upper end of 6, 27 and chassis frame 2 side
9 and 20, which are pivotally connected, and lift arms 19 and 20
Is lifted, the lift arms 19, 20 are fitted to the auxiliary arms 26, 27 and firmly fixed.
Further, the chassis frame 2 and the elevating frame 25 are connected by the hydraulic cylinder 16, and the arms 19, 20 are erected by the extension of the hydraulic cylinder 16, and the elevating frame 25 moves upward while moving backward.

As shown in FIG. 2, the lifting frame 25 includes front and rear horizontal rails 28 and 29, left and right rails 30 and 31 located on the lift arms 19 and 20, and a central rail 32 located at the left and right center.
Are linked to form a framework. In addition, right and left crosses 30, 3
Hooks 7 are provided at the four corners of 1 in an upward direction. On the upper part of the ascending frame 25, the loading platform 5 is pivotally supported at the center thereof by the lifting platform 25, and is rotatably provided with four rollers 33 around the periphery thereof. 34 is a rotation unlocking pedal 90
The lock of the bed 5 which is locked every ° is released. The carrier 5 forms a cargo receiving surface that covers substantially the entire chassis frame 2, and has two guide grooves 35 and 36 at the center in the left and right directions toward the front.
Is formed. Behind this loading bed 5, a horizontally long tool box 3
7 is attached.

The carrier 5 is provided with four holes 6, and the holes 6 are located on the hooks 7 of the lifting frame 25 at the position where the carrier 5 is lowered. It can be hung. The rear portion of the chassis frame 2 is covered with a control box 4 made of a plate, and a start switch 3 and a charging display unit 40 are provided on the upper surface of the control box 4. Antenna 41 for receiving radio waves and emergency stop switch 42
Are provided. With the above-described configuration, the loading platform 5 moves up and down while moving on the front side and the upper side of the control box 4 due to the expansion and contraction of the hydraulic thin lid 16. By raising the loading platform 5, the container and the like are lifted and transported. Become.
