Abstract

(57) [Summary] [Purpose] When operating a vehicle speed limiting device that limits the vehicle speed so that the vehicle speed does not exceed a predetermined speed in a cargo-handling vehicle, the set speed value is displayed to improve the efficiency of driving work. To be able to do it. [Structure] In a vehicle speed display device 1 of a cargo handling vehicle, a set speed value of a vehicle speed limiting device is displayed in a vehicle speed display unit 2 and an operator also confirms that the vehicle speed approaches or reaches a set speed value. Configure so that you can.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle speed display device for displaying vehicle speed and the like in a cargo handling vehicle such as a forklift truck.

[0002]

[Prior Art]

 Conventionally, in a forklift truck, a vehicle speed display device that is provided in front of the driver's seat of the vehicle body and displays the vehicle speed and the like has a vehicle speed display portion having a scale in which the inside of an arc-shaped frame is divided by a plurality of dividing lines. The vehicle speed is recognized by turning on the scale part corresponding to the vehicle speed.

Further, the vehicle speed display device is additionally provided with a vehicle speed limiting device display section, which is lit while the vehicle speed limiting device is operating (ON state) and is not operating (OFF state). The state is turned off to display the operating state (ON, OFF) of the vehicle speed limiting device. This vehicle speed limiter is to prevent the vehicle speed from exceeding a predetermined speed.To ensure the safety of work on a forklift truck, if the operator sets a certain speed, the speed within the set speed Is capable of traveling freely, but when the set speed is reached, the vehicle speed is automatically limited so that no higher speed is reached, and the vehicle can be driven safely.

[0004]

[Problems to be solved by the device]

 With the conventional vehicle speed display device, the operator can recognize the operating state of the vehicle speed limiting device, that is, the ON / OFF state by the vehicle speed limiting device display unit, but the speed at which the vehicle speed is limited, that is, the set speed. Is not displayed, and although the speed does not exceed the set speed, the worker must always consider the set speed during work, and work efficiency is improved. There was a risk of a drop. The present invention aims to solve this problem.

[0005]

[Means for Solving the Problems]

 According to the present invention, a vehicle speed display device for a cargo handling vehicle displays a set speed value of a vehicle speed limiting device, and an operator can confirm that the vehicle speed approaches or reaches the set speed value.

[0006]

【Example】

 One embodiment of the present invention will be described with reference to FIG. As in the conventional case, the vehicle speed display device 1 provided on the front face of the driver's seat of the vehicle body of the forklift truck to display the vehicle speed and the like is formed by a scale divided into a plurality of dividing lines in the arc-shaped frame, The vehicle speed display unit 2 that displays the vehicle speed when the corresponding scale is lit and the vehicle speed limiting device that lights up when the vehicle speed limiting device is operating (ON state) and turns off when the vehicle speed limiting device is not operating (OFF state). And a vehicle speed limiting device display section 3 (for example, a turtle-shaped mark is used) for displaying the operating state (ON, OFF) of.

In the vehicle speed display device 1 configured as described above, the present invention first displays the set speed value of the vehicle speed limiting device on the vehicle speed display unit 2. This is a dial not shown by the operator. When the set speed is set and the vehicle speed limiting device is operated, at the same time, the set speed signal is input to the vehicle speed display unit 2 and the scale corresponding to the set speed value is also turned on. For example, when the operator sets the set speed to 8 km / h, the scale of 8 km / h on the vehicle speed display unit 2 is turned on. Therefore, the operator can appropriately check the set speed of the vehicle speed limiting device while traveling.

Further, in the present invention, when the vehicle speed approaches the set speed value of the vehicle speed limiting device, for example, when the vehicle speed reaches 7 km / h when the set speed is 8 km / h, the set speed value display is turned on (8 km / h). The scale of is configured to flicker. When the vehicle speed reaches the set speed of 8 km / h, the indicator lights from zero display to vehicle speed (all scales from zero display to 8 km / h) are flickered. This allows the operator to instantly confirm that the vehicle speed has approached or reached the set speed.

[0009]

[Effect of the device]

 The present invention is as described above, and can recognize the following situations. By displaying the set speed value of the vehicle speed limiting device on the vehicle speed display device, the worker can appropriately confirm the set speed while traveling. When the vehicle speed approaches the set speed, the display of the set speed flickers, and the operator can confirm that the vehicle speed has approached the set speed. When the vehicle speed reaches the set speed, the operator can instantly confirm that the vehicle speed has reached the set speed by flickering the display lights from zero display to the vehicle speed. Since the situation recognition described above is possible, it is not efficient in the past for the worker to always work while considering the set speed, etc., but according to the present invention, the worker can judge the situation. The burden is reduced and the work efficiency is improved.
