Description

Lamp irradiation angle control device for construction equipment and method therefor

The present invention relates to an apparatus and method for controlling a lamp irradiation angle of construction equipment, and more particularly, when the construction equipment is turned or steered, a flow rate flowing into a swing motor or a driving motor of the construction equipment is sensed with a sensor to detect the flow rate of the construction equipment. To obtain a rotation angle of the construction equipment, and to automatically rotate the irradiation angle of the boom lamp (Boom Lamp) and the cabin lamp in the same direction and angle as the construction equipment, relates to a lamp irradiation angle control apparatus and method of the construction equipment.

Generally. Heavy construction equipment such as dozers, loaders, excavators, and graders are mainly used in earthmoving environments. Among these, the excavator has a wide radius for performing work compared to the size of the equipment, but the blind spot that occurs to the equipment operator due to the characteristics of the excavator (boom, arm) is wider than other vehicle-type equipment. .

Accordingly, as shown in FIGS. 1 and 2, the excavator is provided with a boom lamp (L) on the side of the boom (1) to perform night work, and this boom lamp (L) is always only in a certain area fixed for investigation.

For this reason, frequent safety accidents due to a blind spot caused by the boom lamp (L) fixed at the time of turning, for example, a dark zone, in work in a dark place requiring illumination, or in night work , or falls and falls due to blind spots while driving, and the efficiency of equipment operation is also greatly reduced due to anxiety about accidents. In particular, since turning, which is the main operation of the excavator, is repeatedly performed throughout the working time, it is very important to secure the field of view because there is a high probability that a dangerous situation will occur.

Therefore, when the boom lamp (L) is oriented so that it cannot properly irradiate the work area, the operator manually checks the arrangement position or orientation angle of the boom lamp (L) before or after stopping the vehicle during work each time. I had to deal with the inconvenience of having to adjust.

In addition, when the operator manually adjusts the arrangement position or orientation angle of the boom lamp (L) whenever the work area is changed, not only the work efficiency is greatly reduced, but also the installation position of the boom ramp (L) is high before or during work When adjusting the boom lamp (L) as above, the risk of causing a safety accident was very high.

To solve this problem, Korean Patent Registration No. 10-1387280 was devised.

In the prior patent, the signal generating unit operates by a signal from the outside, and the control unit operates according to the signal generated by the signal generating unit to operate the rotary driving unit and the linear moving driving unit equipped with the boom lamp, so that the irradiation angle of the boom lamp and It is configured to adjust the set position and operates semi-automatically, or automatically responds to changes in the working area of the excavator through the external camera steering angle sensor, boom-arm-bucket angle sensor, or boom-arm-bucket cylinder displacement sensor. It allows you to adjust the irradiation angle or setting position of the boom lamp according to the

However, the boom lamp steering device according to the prior patent operates semi-automatically by a signal from the outside or requires expensive equipment such as a separate external camera and a program to operate this equipment. There is a problem in that even the viewing angle cannot be secured.

Hereinafter, with reference to FIG. 9 , a method for controlling a ramp irradiation angle during turning of an excavator according to an embodiment of the present invention will be described.

First, it is checked whether the boom lamp 160 is operating (S910).

In step S910, if the boom lamp 160 is not in operation, it is terminated, and if the boom lamp 160 is in operation, when the Kevin lamp 510 is rotated, in order to prevent interference with the irradiation of the boom lamp 160 It is confirmed whether the boom 130 rises at a right angle (S920).

In step S820, if the boom 130 does not rise at a right angle, the turning operation stops and ends, and if the boom 130 rises at a right angle, it is checked whether the flow rate flows into the swing motor 717 (S930).

In addition, when the construction equipment is steered or turned, it is possible to secure a side view angle when necessary only with the cabin ramp and boom ramp.

As described above, the present invention has been described based on the preferred embodiments, but these embodiments are intended to illustrate, not to limit the present invention. Various changes, modifications, or adjustments to the examples are possible. Therefore, the protection scope of the present invention should be construed to include all examples of changes, modifications, or adjustments belonging to the spirit of the present invention.
