Description

[Detailed description of the invention] The present invention relates to a display panel for a tower crane.

A tower crane generally has a structure as shown in Fig. 1, in which the crane body lV'c is established, and 3 tower jibs are installed at the upper part of 9 tower posts 2 so that they can move freely. Because of the height of the tower crane, when installing it, it is necessary to constantly detect and monitor the inclination angle of the tower post and the wind direction and speed during work to avoid the risk of tipping over.

The present invention aims to improve the display panel for detecting these and accurately conveying the results to the driver, and the first invention includes a wind direction/wind speed detector attached to a tower post of a tower crane and an inclination angle. On the display panel that displays the detection results on the driver's cab of the crane, there are four
The second invention is w, and the first invention is characterized in that the combination of the indicator light and the digital display window can display the wind direction and wind speed or the direction and inclination angle by switching.
When any one of the four indicator lights lights up on the wind speed display, it indicates the wind direction within a range of 22.5 degrees to the left and right around the center of the lighting direction. From 1st to 2nd time, the 2 points are lit to show the wind direction in a range of 22°5° to the left and right, centering on center 1.The direction and inclination angle display is indicated by one of the 144 indicator lights in front, and it is lit at 9 o'clock. According to the third invention, in the first invention, when all of the four indicator lights are lit, the wind direction/wind speed detector indicates the angle of inclination. Select all detections and display the failures of 90,000 detectors.
This is a special feature.

An embodiment shown in FIG. F will be described below.

As shown in Figure 8g1, a wind direction/wind speed detector 5 is installed at the top of the tower post 2, a tilt angle detector 6 is installed at the bottom, and a reminder display board 7 is installed on the driver's cab to display the detection results. .

Display panel 7μ As shown in Figure 2, wind direction, wind speed, or direction can be determined by combining the 4-point indicator lights 8 arranged front to back and left and right on the left of the center of the board and the digital display window 9 placed to the right or center. Display by changing all tilt angles.

In the case of wind direction/wind speed display, when the wind direction/wind speed push button IO button in the lower row of the display panel 7 is operated, the 4-point indicator light 8 will light up the front and left two points in succession as shown in Figure 3 (-). (
If the one point on the right lights up as shown in b), it indicates that the wind is coming from the area on the right indicated by diagonal lines, and the wind speed at this time is indicated in the digital display window 9 as, for example, 1,888 m/s. show. To the right of the digital window 9 are two indicator lights 11 and 12a indicating which of the wind direction/speed and the tower post inclination angle has been selected, and when the indicator light 11 lights up, the inclination angle is Have you selected the wind direction and wind speed when the indicator light 12 lights up? It shows.

Next, if you want to switch to displaying the inclination angle of tower post 2,
When you press the corner pushbutton 13 after the 11th tower in the lower row, either the front or rear indicator light of the 4-point indicator light 8 lights up, for example!
If the front position lights up as shown in FIG. 4(a), it will be displayed on the tower post 2 that it is tilted 1.888 degrees in the front direction.

Similarly, when the tower left/right angle push button 14 is pressed, the left and right inclination angles of the tower post 2 are displayed. In addition, there are 2m each of angle sensors in the rear and left and right directions in the tilt detector 6.
The average value of both is displayed, and when the difference between the two is more than a specified value, for example 0.3 degrees or more, it means that one of the sensors is defective. As shown in FIG. 2, all four indicator lights 8 are lit to indicate that the angle sensor is malfunctioning, and the digital display window 9 is configured to display only a horizontal line.

Even when the wind direction/wind speed detector 5 becomes defective, all four points are displayed in the same manner.

Indicator light 15.1 of the tower front and back angle is placed on the upper part of the display panel 7.
6 is arranged, and the indicator light 16 lights up in yellow to warn when the tower post 2 is in the range of 1c90' to 85° in the front and back direction, and when it tilts backward from the vertical direction. The indicator light 15 will light up in red to warn you. When the wind speed becomes dangerous, for example, 10m/s or more, the indicator light 17 lights up in red to display a warning. It is also possible to use a buzzer in combination with cn et al.

Also, the t source switch 18 is r (power supply table when JNJ) I (
Light 19 lights up in green.

Since the present invention is constructed as described above, it is an excellent invention that contributes to the improvement of safety by achieving the following effects compared to the conventional & non-displacement systems.

(1) Wind direction/speed and tower post inclination angle are displayed by switching, so the display panel is small and easy to read.

(2) It is extremely convenient because the wind direction and slope direction can be distinguished by lighting combinations of 4-point indicator lights.

(3) You can also know if the detector is malfunctioning with the 4-point indicator light.
Extremely safe.

(4) The combination of digital display, warning lamps and buzzer makes it easier to sleep and drive by knowing the situation quickly and accurately.
