Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an excavation guide apparatus for a construction machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction machine, and more particularly, to a digging guide device for a construction machine capable of providing a driver of a construction machine with a laser beam on the ground in a visual and real- .

Construction machines used in construction sites are used for large civil engineering and construction works such as roads, airports, and housing complexes. Among these construction machines, excavators are the most used.

Generally, excavators perform works such as excavation work for digging the ground in civil engineering, construction, construction site, loading work for carrying earthworks, crushing work for dismantling the building, and cleaning work for arranging the ground. At this time, the excavation work includes an excavation process of digging the soil according to a predetermined excavation position, depth and slope at the construction site, and a confirmation survey process to determine whether the excavation process being performed matches the target excavation position, depth, and slope do.

Specifically, most of the excavation work depends on the visual guessing of the driver of the excavator and on the driver's senses, or skill. In other words, since the excavation work is carried out by the visual guessing of the excavator operator and the technique of the driver of the driver, there is a large error in the excavation position, depth, inclination and target excavation position, depth, do. Accordingly, the driver performs double excavation to fill up the excavation position, depth, and slope of the error generated by using the soil extracted during the excavation process. As a result of performing the double excavation, the work time required for the entire excavation work increases and the cost of excavation work also increases.

Meanwhile, as described above, the excavation work is repeatedly performed during the excavation process to perform an accurate surveying process so as to reduce the error between the current excavation position, depth, slope, target excavation position, depth, and slope. However, since the confirmation surveying process is performed during the excavation process, the excavator needs to wait while the excavator is started, which increases the cost of the excavation work and increases the time required for the work.

In recent years, an intelligent device has been developed in which a separate monitoring device is installed in an excavator so that a driver can precisely perform excavation work while confirming current excavation position, depth, and tilt information through a monitor image. However, these intelligent devices are very expensive and require expert knowledge in order to use intelligent devices, which makes it difficult for an excavator driver to use them easily.

Accordingly, there is a demand for development of an excavation guide device which can guide a driver of an excavator to work while confirming current excavation position, depth and inclination during actual excavation work, and is easy to use at low cost.

The present applicant has proposed the present invention in order to solve the above-mentioned problems. As a prior art document related thereto, Korean Patent Publication No. 10-2015-0102445 (entitled " A work control device and a method thereof, public disclosure date: 2015.09.07).

The driving member 126 may be one of the general motor types and is preferably provided as a step motor to finely adjust the projection angle of the green lens module 124a and the red lens module 124b, But the present invention is not limited thereto.

Referring to FIG. 1, the control unit 130 controls the laser beam of the light irradiation unit 120. In detail, the controller 130 controls the light irradiating unit 120 based on the target excavation position, the depth, and the slope information inputted in advance based on the topographic information for the excavation work of the construction machine 1, Can be displayed on the paper surface. At this time, the control unit 130 can automatically or manually control the projection length, the projection direction, or the projection angle of the laser beam emitted from the light irradiation unit 120. For example, when the control unit 130 manually controls the light irradiating unit 120, it can be adjusted according to the user's setting by using a button (not shown) or a dial (not shown). Although not shown in the drawing, an interface (not shown) and an automatic adjustment module (not shown) must be separately provided for the control unit 130 to automatically control the light irradiation unit 120.

In addition, the controller 130 may adjust the output intensity of the laser beam emitted from the light irradiation unit 120. The control unit 130 may sense the ambient illuminance of the construction machine 1, that is, the guide device 100 according to an embodiment of the present invention. The control unit 130 may adjust the output intensity of the laser beam emitted from the light irradiation unit 120 according to the sensed illumination result. For example, when the periphery of the guide apparatus 100 is bright, the output intensity of the laser beam emitted from the light irradiation unit 120 is increased, and when the periphery is dark, the output intensity is reduced.

Meanwhile, although not shown in the figure, the controller 130 may include a battery member (not shown) for stable driving of the guide device 100. The battery member (not shown) may be a power supply unit capable of supplying power to the light irradiating unit 120, the driving member 126, or the control unit 130, and may be provided as a general power supply unit.

Referring to FIG. 1, a guide device 100 according to an embodiment of the present invention may further include a cradle 140. The holder 140 is a member for positioning and supporting the main body 110 on the ground. Specifically, the holder 140 is provided at the lower end of the main body 110, so that the main body 110 can be positioned on the ground. The holder 140 may be provided in the form of a holder for supporting a general camera or the like. At this time, the number of legs of the cradle 140 and the shape of the cradle 140 may vary depending on the topography where the guide device 100 is located, the environment in which the construction machine 1 is working, and the like.

In addition, a horizontal adjuster 142 may be provided on the above-mentioned stand 140. The horizontal adjuster 142 is a member for measuring or adjusting the level of the main body 110. In other words, the horizontal level of the main body 110 can be adjusted in accordance with the horizontal level of the ground or topography to be excavated by the level adjuster 142 provided in the mount stand 140. The level adjuster 142 may be provided as a sensor capable of measuring the inclination of the ground.

The laser beam can be emitted to the ground after aligning the level of the main body 110 or the light irradiating unit 120 using the level adjuster 142 when the main body 110 is placed on the ground. On the other hand, at the site where excavation work is performed by the construction machine 1, since various construction machines and a plurality of workers move while performing work, the main body 110 or the light irradiation part 120 maintains the initial horizontal level It may not be possible. Accordingly, when the laser beam is projected on the ground in a state in which the main body 110 is misaligned, errors may occur with the target position, depth, or inclination, which is initially set information. Therefore, It is desirable that the process of making and adjusting is repeatedly performed.

As described above, the horizontal adjuster 142 of the guide apparatus 100 according to an embodiment of the present invention measures the horizontality of the main body 110 in real time during the excavation work, If there is a difference in level, the result can be informed to the driver or auxiliary operator of the construction machine (1). To this end, the guide device 100 may further include an alarm unit 150 described later.

In addition, it is also possible to automatically restore the horizontal level when it is measured that there is a difference between the initially set horizontal level. That is, the controller 130 controls the horizontal or stand height 140 of the main body 110 to adjust the level of the main body 110 automatically by driving the horizontal adjuster 142 or a height adjuster 144 Or recover it. In other words, if the horizontality measured by the horizontal adjuster 142 is different from the initial set horizontal level, the horizontal level may be automatically adjusted by driving the driving unit (not shown) of the horizontal adjuster 142 or the elevator adjuster 144. The drive unit of the height adjuster 144 is controlled by the control unit 130 and the measurement result of the horizontal adjuster 142 can also be transmitted to the control unit 130. [

Further, the elevation adjuster 144 may be provided on the holder 140. The height adjuster 144 is a member for adjusting the distance between the main body 110 supported by the holder 140 and the ground. As shown in FIG. 1, the height adjuster 144 may be provided on at least one or more legs of the cradle 140. On the other hand, the height adjuster 144 may be replaced by providing the legs of the cradle 140 in a height-adjustable form.

Further, although not shown in the drawing, a separate fixed footrest (not shown) may be provided at the lower end of the cradle 140 so that the body 110 can be firmly fixed to the ground. The guide device 100 can be stably positioned or fixed on the ground by providing a fixed footrest (not shown) at the lower end of the mount 140. As described above, the height adjuster 144 may further include a drive unit (not shown) for automatically adjusting the height of the main body 110.

Meanwhile, the guide device 100 according to an embodiment of the present invention may further include an alarm unit 150. Specifically, the alarm unit 150 detects whether the construction machine 1 is performing an accurate excavation operation based on the target excavation position, depth, and inclination information displayed on the ground from the light irradiation unit 120, Depth and tilt information are compared with actual excavation position, depth, and tilt information to alert the driver of the construction machine (1) or the auxiliary manpower around him if an error occurs. In other words, the control unit 130 determines whether the construction machine 1 is performing the correct operation based on the target excavation position, depth, and tilt information displayed on the ground, and periodically determines the result of the construction machine 1 It informs the driver or an assistant in the vicinity. At this time, it is possible to inform the driver or the auxiliary assistant around the alarm unit 150 through a warning sound or to inform the assistant using the lens module 124 of the light irradiation unit 120. For example, if the construction machine 1 does not have an excavation position, a depth, and a slope that are set in advance, and the target excavation position, the depth, and the inclination are not in error, the alarm unit 150 may be inactivated or the green lens module 124a By turning it on, you can tell that there is no abnormality. On the other hand, if the excavation position, depth and inclination of the construction machine 1 during actual work are set to a preset target excavation position, depth, inclination and error, the alarm unit 150 is activated to generate a warning sound, 124b) to indicate that an error has occurred.

As described above, the alarm unit 150 can operate even when the level measured by the level adjuster 142 is different from the initial set value.

As described above, the control unit 130 can control the projection length, the projection direction, or the angle of the laser beam emitted from the light irradiation unit 120. Accordingly, the guide apparatus 100 according to an embodiment of the present invention can be used to guide a target excavation position, excavation depth, or excavation slope information to a ground surface where excavation work is to be performed using the laser beam emitted from the light irradiation unit 120 The driver of the construction machine 1 can guide the operator of the construction machine 1 to perform a precise excavation work while viewing the laser beam with the naked eye.

Hereinafter, the principle of displaying the excavation position, depth, and tilt information on the ground using the guide apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 3 to 8. FIG.

FIG. 3 shows an example of guiding the position to the ground where a digging operation is to be performed using a laser beam. Referring to FIG. 3, the angle of the light irradiation unit 120 is adjusted so that one or more laser beams L1 and L2 emitted from the two lens modules 124 of the light irradiation unit 120 are displayed on the ground. The first laser beam L1 or the second laser beam L2 is displayed on the ground in the light irradiating unit 120 with the angle adjusted to face the ground so that the driver of the construction machine 1 can obtain the target excavation position The target excavation area can be displayed on the ground. Accordingly, the driver of the construction machine 1 can perform the excavation work at the correct position while visually observing the laser beams L1 and L2 displayed on the ground.

FIG. 4 shows an example of guiding the depth of excavation using a laser beam. As shown in FIG. 4, the target excavation depth is displayed on the ground using the visual characteristics appearing when the two laser beams emitted from the two lens modules 124 converge to one point or converge to one line can do. Specifically, as shown in Fig. 4A, the laser beams L1 and L2 emitted from the two lens modules 124 are converged at one point or one line at the same target excavation depth (D) The distance between the two laser beams L1 and L2 becomes narrower as the laser beam approaches the target depth D. As a result, the target excavation depth D), one point or one line. In other words, as shown in FIG. 4B, the control unit 130 adjusts the output direction and the irradiation angle of two or more laser beams of the light irradiating unit 120, and is focused at the target depth D It should be represented as one point or one line. At this time, the driver of the construction machine 1 confirms whether the laser beams L1 and L2 shown by the naked eye are gathered by one point or one line, and sequentially from the starting point of the ground E to the end point of the target depth D When excavated, it is possible to excavate accurately to the target depth (D).

5, the setting of the rotation angle of the light irradiation unit 120 for irradiating the laser beam corresponding to the target excavation depth D from the light irradiation unit 120 will be described.

5, the two laser beams B emitted from the light irradiating unit 120 are gathered at one line at the target depth D to form the crossing lines O and O ' The light irradiation unit 120 may be rotated at the same angle, or only one of the light irradiation units 120 may be rotated. 5, the light irradiation unit 120 located on the left side is referred to as a first light irradiation unit A and the light irradiation unit 120 located on the right side is referred to as a second light irradiation unit A 'in FIG. 5A shows the first light irradiating part A and the second light irradiating part A 'rotating in the same angle, and FIG. 5B shows the first light Only the irradiation unit A rotates. Since the principle of the method (a) of FIG. 5 is the same as the principle of the method of FIG. 5 (b), the method of FIG. 5 (a) will be described below.

In FIG. 5A, h is the height of the guide device, D is the target (excavation) depth, c is the distance between the centers of the first light irradiation portion A and the second light irradiation portion A ' 1 and the second light irradiation portions A, A '. The laser beam B is emitted from the first light irradiation portion A and the second light irradiation portion A 'and the two laser beams B are emitted from the center between the first and second light irradiation portions A and A' So as to generate one crossing line O. At this time, the rotation angle [alpha] of the first light irradiation part A and the second light irradiation part A 'can be obtained by the following equations (1) and (2).

(1) is a formula for obtaining the rotation angle [alpha] of the first and second light irradiation portions A and A 'in the case of FIG. 5 (a) is a formula for obtaining the rotation angle [alpha] of the first light irradiation portion A with respect to the case of b).

In this case, since two laser beams are displayed in the area where the line O is missing or off, the driver of the construction machine 1 can grasp the accurate target excavation depth D with the naked eye and perform excavation work.

6, when the irradiation direction is adjusted so that the laser beam emitted from the light irradiating unit 120 is focused on the work surface having the inclination in a straight line, the target excavation of the construction machine 1 is performed on the work surface having the inclination, The slope can be displayed. In other words, at least two lens modules 124 are provided in the light irradiation unit 120, and two or more laser beams L1 and L2 are emitted from the two lens modules 124 to the working surface having a slope, The light irradiating unit 120 is adjusted so as to appear as a line in the form of a line. That is, the driver of the construction machine 1 can perform the excavation work up to a predetermined target excavation slope by digging to the point where one line appears on the work surface having the inclination.

On the other hand, as shown in Fig. 6, the work surface is shown to have two slopes, the lower work surface has a gentle slope than the target slope, and the upper work surface has a target slope. Therefore, the lower work surface must be machined until the lower work surface becomes the same slope as the upper work surface. At this time, if the light irradiation unit 120 is adjusted so that the laser beams L1 and L2 converge on one line on the working surface having the target inclination and the laser beams L1 and L2 are emitted to the working surface, The laser beam is not gathered but appears as two.

Referring to FIG. 7, setting of the rotation angle of the light irradiation unit 120 for irradiating a laser beam corresponding to the target excavation slope from the light irradiation unit 120 will be described.

As shown in FIG. 7, two light irradiation units 120 are provided so that two laser beams L1 and L2 are emitted. The laser beams L1 and L2 emitted from the two light irradiation units 120 are displayed parallel to each other on the ground surface and the two light irradiation units 120 are rotated equally by a predetermined angle? . Then, the two laser beams L1 and L2 are gathered to create the line O. Since the two laser beams L1 and L2 appear in the region where the two laser beams L1 and L2 do not reach the point of the intersection O and the operator of the construction machine 1 performs accurate target excavation The slope can be grasped visually and excavation can be performed.

Referring to FIG. 8, a method of guiding an excavating operation using the excavating guide apparatus 100 of a construction machine according to an embodiment of the present invention will be described.

First, the control unit 130 confirms excavation position, depth, or tilt information previously designed on the ground where the construction machine 1 performs the excavation operation, and then inputs the designed excavation position, depth, or tilt information (S110). At this time, it is preferable that such information is transmitted to the control unit 130. [

Then, the guide device 100 according to an embodiment of the present invention is set up and fixed at a position where it is not disturbed by the digging operation of the construction machine 1, and the height and the level of the holder 140 are adjusted. At this time, it is preferable that the position of the guide apparatus 100 is located on the front side of the construction machine 1 so that the laser beam with respect to the excavation position, depth, or tilt information emitted from the guide apparatus 100 can be visually confirmed.

Then, the laser beam is emitted from the light irradiating unit 120 by the control unit 130, and the target excavation position, depth, or tilt information is displayed on the ground so that the excavation operation is performed (S120). At this time, the shape of the laser beam with respect to the target excavation position, depth, or tilt information displayed on the paper may vary depending on the number of the main body 110 provided with the light irradiation unit 120 and the control unit 130 therein.

Then, the control unit 130 determines an error between the excavation work being performed and the laser beam displayed on the paper surface (S130). Specifically, information on the ground during the excavation work and the target excavation position, depth, or tilt information displayed on the ground from the light irradiation unit 120 are sensed in real time. If it is detected that there is an error between the ground information in the excavating operation and the information of the laser beam emitted from the light irradiating unit 120, the operator of the construction machine 1 or an auxiliary assistant around the operator is alerted at step S140. A method of alarming an error may be informed by using an alarm unit 150 as a warning sound or may be visually identifiable to an operator or assistant force by using the lens module 124 of the light irradiation unit 120.

According to the construction described above, in the excavating operation guide apparatus 100 of the construction machine according to the embodiment of the present invention, in the excavating operation of the construction machine, the operator of the construction machine repeatedly It is possible to greatly reduce the time required for the digging operation of the construction machine by displaying the excavation position, depth, or tilt information on the ground by using the laser beam, unlike the conventional technique of performing the confirmation survey and excavation work, Thereby preventing waste of human resources and equipment.

Further, since the excavation guide apparatus 100 of the construction machine of the present invention displays the excavation position, depth, or tilt information directly on the ground using one or more laser beams, it is possible to minimize the number of auxiliary workers around the construction machine It is possible to prevent a safety accident that may occur during excavation of a construction machine.
