Abstract

PURPOSE: To reduce load on an arm by providing a running lever for advancing separately from a grip. CONSTITUTION: A running operation device 6 is provided on the right side face of the control box 7 of a driver's cab 4, and a grip 8 is provided to move a vehicle forward and backward by being turned. Besides this grip 8, a running lever 9 is tiltably provided for only advancing the vehicle at an upper position near the grip 8. For advancing the vehicle, the operation of only the running lever 9 is enough, and it is not necessary to continuously turn and hold the grip 8, reducing the load on the arm more than in a conventional way. Since the vehicle can be advanced without continuing the same operation, the load on the arm is more reduced, making long time operation easy.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle running control device in which the arm operated by a driver is prevented from being touched more.

[0002]

2. Description of the Related Art Conventionally, in a vehicle which is moved forward or backward by rotating a grip, only a grip for moving the vehicle forward or backward by rotating is provided.

[0003]

In the above-mentioned conventional structure, the vehicle is moved forward or backward by only rotating the grip. Therefore, when the vehicle continues to move forward for a long time, the grip is rotated in the forward direction. There was a problem that I had to keep holding it and my arm got tired. The present invention has been devised to solve the above problems.

[0004]

DISCLOSURE OF THE INVENTION According to the present invention, in a vehicle which is moved forward or forward or backward by rotating a grip, a forward traveling lever is provided separately from the grip so that the vehicle only moves forward. The above problems are solved.

1 is a front view of an order picking vehicle embodying the present invention, 1 is an order picking vehicle, 2 is an order picking vehicle 1 Of the vehicle body, 3 is a mast standing on the rear of the vehicle body, 4 is a driver's cab that moves up and down along the mast 3, 5 is a pair of forks fixed to the lower surface of the driver's cab 4, and 6 is the order picking vehicle 1. It is a traveling operation device for moving forward and backward.

FIG. 2 is a front view of the traveling operation device of the present invention.
A traveling operation device 6 is provided on the right side surface of the control box 7 of the cab 4, and a grip 8 for moving forward and backward by a rotating operation and a forward traveling lever 9 for instructing only forward movement are provided near the grip 8 in a tiltable manner. There is.

FIG. 3 is a sectional view of the traveling operation device of the present invention.
The shaft 10 is formed at one end of the grip 8.
A pair of cams 11 and 12 are fixed to the shaft 10, and contact with convex portions formed on the outer circumferences of the cams 11 and 12 to activate either the forward limit switch 13 or the reverse limit switch 14. , The order picking vehicle 1 starts traveling in either the forward or reverse direction.

FIG. 4 is a control circuit diagram of the present invention. In the control circuit, an exciting coil 16 of a forward contactor is provided in a forward limit switch 13 and a second contactor is operated when the forward traveling lever 9 is operated. Via the first normally-closed contact X1-b of the second contactor, and the exciting coil 17 of the reverse contactor in the reverse limit switch 14 operates as the second contactor of the second contactor that operates when the forward travel lever 9 is operated. Closed contact X2
A limit switch 15 that is connected in series via -b and that operates when the forward drive lever 9 is operated.
And the exciting coil 18 of the second contactor are connected in series.

FIG. 4 is a main circuit diagram of the present invention. In the main circuit, a traveling motor 19, a forward / reverse switch 20 and a chopper device 21 are connected in series.
When the forward limit switch 13 is activated, the forward / reverse selector 20 is switched to the forward side and the chopper device 2
1, a speed control signal is applied, the rotation speed of the traveling motor 19 is controlled in proportion to the speed control signal, and the vehicle travels in the forward direction.

The vehicle which moves forward or backward by rotating the grip according to the present invention moves forward or backward by rotating the grip of a walkie-type forklift, a bar-handle type electric vehicle or the like, in addition to the order picking vehicle illustrated above. It is a concept that includes vehicles.

[0011]

As described above, according to the present invention, since the vehicle can be moved forward without making the same rotation operation permanent, the burden on the arm is further reduced as compared with the conventional one, and the vehicle can be operated for a long time. It will be easier to do.
