Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a control device for a container transport vehicle.

<Prior Art> Conventionally, as shown in FIG. 1, in a container transport vehicle, a driver's cab 2 is provided on the upper part of a portal-shaped vehicle body 1, and a container suspension frame 3 that can be freely raised and lowered is provided in the midsection of the vehicle. When the operator went up and down to the operator's cab 2, he used the ladder A, which required a lot of effort and was dangerous.

<Purpose> The present invention was made in order to solve the above-mentioned problems, and aims to provide a control device that can be operated by an operator when climbing up and down a frame for hanging a container that moves up and down.

<Example> Hereinafter, the present invention will be explained based on the embodiments shown in FIGS. 2 to 5. The device of the present invention has a driver's cab 2 on the upper part of the portal-shaped vehicle body 1, and a container suspended in the midsection that can be freely raised and lowered. In a container transport vehicle provided with a frame body 3, a start switch 5 for starting the engine 4 and a stop switch 6 for stopping the engine 4 located at the upper part of the vehicle body 1, a lift switch 7 for raising the frame body 3, and a lowering switch for raising the frame body 3 are provided. An operation panel 9 having a lowering switch 8 is provided at one end of the frame 3, and an operator guard B is provided at the one end.

In addition, in this embodiment, the switches 5, 6,
By means of an electric device operated by 7, 8, the engine 4
The solenoid valve that operates the hydraulic system for raising and lowering the frame 3 is also operated.

The electric device and the electromagnetic valve are provided in the operator's cab 2, and an electric cable 10 connecting these and the operating panel 9 is provided between the operator's cab 2 and the operating panel 9. Of course, a cable winding device is provided on the driver's cab side of the electric cable 10.

Further, together with the operation panel 9, a floor 11 and a handrail 12 are provided at the rear left end of the frame 3, and these 11 and 12 constitute the guard B. In the figure, 13 is the floor of the driver's cab 2, and 14 is a chain for suspending the frame.

Next, the operation will be explained. Normally, when the vehicle is stopped, the frame 3 is lowered to the ground.
In this state, the operator gets on the floor 11 of the frame 3 and operates the start switch 5 of the engine 4 to start the engine 4. When the engine 4 rotates, pressure oil is sent to the hydraulic system. In this state, when the lift switch 7 is operated, the frame 3 rises. When the heights of the floor 11 of the frame 3 and the floor 13 of the driver's cab 2 reach the same level, the lift switch 7 is released and the frame 3 is stopped at that position. Then, the operator gets into the operator's cab 2 and performs normal operation.

Next, when exiting the vehicle after completing the cargo handling work, the frame 3 is first raised inside the driver's cab 2 so that the floor 11 and the floor 13 of the driver's cab 2 are at the same height. Then, the operator leaves the operator's cab 2 and transfers to the floor 11 of the frame 3. Next, when the lowering switch 8 is operated, the frame 3 is lowered. When the frame 3 touches the ground, the user releases the lowering switch and operates the stop switch 6 of the engine 4 to stop the engine 4. Then, the operator
descend to the ground.

<Effects> As is clear from the above explanation, the control device of the present invention has a switch for starting and stopping the engine and a switch for raising and lowering the frame at one end of the container suspension frame. It is equipped with a board,
An excellent effect is that the operator can easily and safely get in and out of the high-position operator's cab by using the raising and lowering of the frame.
