Description

CONSTRUCTION MACHINE

The present invention relates to a construction machine, and more particularly, to a construction machine capable of controlling the height of a headlight by determining whether a construction machine such as a wheel loader is traveling.

The loader performs excavation work for excavating soil, sand, transporting work carrying excavated soil, loading and unloading work on the cargo vehicle, road stop work, snow removal work, traction work etc. And is widely used.

These loaders include crawler type loaders and wheel loaders. The crawler type loader has a large traction force although it is slow in running speed, so it can effectively carry out the work of piling up soil, sand and gravel, and is effective in wetland, livelock, limb work and easy to work in narrow places Do.

In addition, the wheel loader type loader has the advantages of working on relatively dry terrain, speeding up work, excellent driving performance, and quick operation speed.

Such a loader is constituted by a boom installed on the front side of the vehicle and operated by a boom cylinder, and a bucket rotatably fixed to the front end of the boom and operated by a bucket cylinder.

Such a bucket is located at the front of the vehicle when the boom descends and rises to a relatively high position from the ground by the boom so that a powdery work such as soil, sand or the like can be conveniently loaded on a freight vehicle or the like.

At this time, the wheel type loader can be flexibly changed when starting, so it is widely used at the present work site.

Meanwhile, a head lamp is provided so that the driver can grasp the movement of the bucket during night work using the loader.

Conventional headlights are mounted through pipe structures at positions adjacent to both side booms of the front frame of the loader so that the driver can see the front of the vehicle and the bucket.

However, the height at which the headlamp is installed does not interfere with the driver's vision at the time of operation, but it is difficult to secure the visibility of the driver because the pipe structure supporting the headlamp can not be adjusted when the loader runs.

In addition, there is a possibility of occurrence of an accident due to the inability of securing the view of the driver.

An embodiment of the present invention provides a wheel loader capable of adjusting the vertical height of a headlight in accordance with work and driving.

According to an embodiment of the present invention, there is provided a construction machine comprising a main body of a construction machine, a headlamp disposed on one side of the main body, a height adjusting device connected to the headlamp to adjust the height of the headlamp, If the height of the headlight is increased according to the determination and the construction machine meets a preset driving condition and if the height of the headlight is not matched with the predetermined driving condition, And a control device for applying a signal for lowering the height of the height adjustment device to the height adjustment device.

Further comprising: a speed sensor for sensing a speed of the construction machine; and an angle sensor for sensing an angle between the working machine of the construction machine and the ground, wherein a speed value sensed by the speed sensor is not less than a predetermined value, The height of the headlight can be increased by controlling the control device when the value is less than a preset value.

And a controller for controlling the control device to increase the height of the headlight when the duration is longer than a predetermined time.

Further comprising a GPS for determining the position of the construction machine and transmitting the position data to the control device, wherein the control device controls the height adjusting device to adjust the height of the headlight according to the position data detected by the GPS .

According to the embodiment of the present invention, the vertical position of the headlight of the construction machine can be adjusted, thereby securing the visibility of the driver.

In addition, it is possible to prevent a safety accident that may occur due to uncertainty of the driver's sight.

1 is a perspective view of a construction machine according to an embodiment of the present invention.
2 and 3 are operational circuit diagrams for adjusting the height of the headlamp shown in Fig.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

The drawings are schematic and illustrate that they are not drawn to scale. The relative dimensions and ratios of the parts in the figures are shown exaggerated or reduced in size for clarity and convenience in the figures, and any dimensions are merely illustrative and not restrictive. And to the same structure, element or component appearing in more than one drawing, the same reference numerals are used to denote similar features.

The embodiments of the present invention specifically illustrate ideal embodiments of the present invention. As a result, various variations of the illustration are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture.

Hereinafter, a construction machine according to an embodiment of the present invention will be described with reference to FIGS.

1 to 3, a construction machine according to an embodiment of the present invention includes a main body 10, a headlamp 20, a height adjustment device 30, and a control device 40. As shown in FIG.

When the construction machine according to an embodiment of the present invention is a wheel loader, the main body 10 is divided into a front frame 11 and a rear frame 12. [

Work machines such as a boom 13 and a bucket 14 are disposed on the front frame 11 and parts for driving a work machine such as a boom 13 and a bucket 14 are arranged on the rear frame 12 .

The headlamp 20 is disposed in the main body 10. Specifically, one or more pieces may be disposed on one side of the front frame 11, and one piece may be disposed on both sides of the boom 13 as a center.

The height adjusting device 30 is connected to the headlamp 20.

The height adjusting device 30 according to an embodiment of the present invention may be formed as an electric cylinder capable of varying the height in the longitudinal direction.

That is, one end of the electric cylinder is connected to the lower end of the headlight 20, and the other end of the electric cylinder is fixed to the front frame 11.

The control device 40 determines whether the vehicle is under construction or in operation, and controls the height adjustment device 30 according to the determination.

The control device 40 may include a determination unit 41 and a control unit 42.

The determination unit 41 determines the state of the construction machine.

Specifically, the speed of the construction machine and the position of the work machine such as the boom 13 and the bucket 14 of the construction machine are detected, and based on the sensed information, it is judged whether the construction machine meets predetermined driving conditions.

Here, the judging unit 41 includes a speed sensor 411 for detecting the speed of the construction machine to determine whether the construction machine meets the driving conditions, an angle sensor 411 for sensing the angle between the working machine of the construction machine and the ground, (412).

The driving conditions for determining whether or not the construction machine is running according to an embodiment of the present invention are as follows.

The speed sensor 411 detects the speed of the construction machine.

Specifically, when the vehicle speed of the construction machine detected by the speed sensor 411 is within 20 km to 30 km, it is determined that the construction machine is running.

Here, in the case of the wheel loader, the heavy material is loaded on the bucket 14 and the work area is moved. Then, the boom 13 is operated to lower the weight applied to the bucket 14.

At this time, it is difficult for a wheel loader loaded with a heavy object to make a speed of 20 km or more due to a safety problem.

In addition, even if the wheel loader travels on the road, since the wheel loader itself is heavy, the traveling performance of the wheel loader may become too fast and the performance of the wheel loader may be deteriorated, so that it is practically difficult for the wheel loader to travel at a speed of 30 km or more.

Accordingly, it is most preferable to set the speed setting value for determining whether the construction machine is traveling according to an embodiment of the present invention within 20 km to 30 km.

The angle sensor 412 senses the angle formed by the working machine and the ground G. [

More specifically, as shown in Fig. 1, a virtual line is drawn from the lowermost end of the bucket 14 to the wheel bottom of the wheel loader, and when the angle? Between the imaginary line and the ground G is 15 degrees or less It is judged that the machine is running.

Here, the boom 13 and the bucket 14 are positioned on the front face of the wheel loader. In order to drive the wheel loader, the boom 13 and the bucket 14 must be lowered to a level that does not hit the ground, so that the driver's field of view is ensured and smooth running is possible.

Therefore, it is most preferable to set the angle setting value for determining whether the construction machine is traveling according to an embodiment of the present invention to be within 15 degrees which is not disturbed by the driver's view.

The control unit 42 applies a signal for adjusting the height of the headlight up and down. The controller 42 according to an embodiment of the present invention may be a relay.

If the speed of the construction machine determined by the determination unit 41 and the angle θ between the lower end of the bucket 14 and the ground G match the predetermined driving condition, A signal is applied to the height adjusting device 30 by the control part 42. [

Conversely, if the speed of the construction machine determined by the determination unit 41 and the angle [theta] formed by the lower end of the bucket 14 and the ground G do not match the predetermined driving condition, the height of the elevated headlight 20 The control unit 42 applies a signal to the height adjusting device 30. [

The construction machine according to an embodiment of the present invention may further include a timer 50 for detecting a duration of a predetermined driving condition.

The timer 50 may be disposed between the determination unit 41 and the control unit 42, but is not limited thereto.

The timer 50 senses the duration of the running condition of the construction machine. The driving condition continuation setting time of the timer 50 can be changed according to the traveling environment and the working environment of the construction machine.

The operation of the headlamp 20 of the construction machine having the above-described configuration will be described with reference to FIGS. 2 and 3. FIG.

 The vehicle speed and the angle? Of the construction machine are detected by the determination unit 41 of the control device 40, that is, the speed sensor 411 and the angle sensor 412.

When the vehicle speed of the detected construction machine is less than 20 km and less than 30 km and the angle formed by the bucket 14 and the ground G is 15 degrees or less, the vehicle speed and the duration of the angle θ are sensed through the timer 50.

If the construction machine meets the driving conditions and the duration of the condition exceeds the predetermined time set value in the timer 50, the control unit 42 increases the height of the headlamp 20 to the height adjusting device 30 Signal is applied. Thus, the height of the headlamp 20 is increased.

On the contrary, when the construction machine does not meet the driving condition, a signal for lowering the height of the headlamp 20 is applied to the height adjusting device 30 by the control part 42. Thus, the height of the headlamp 20 is reduced.

The construction machine according to an embodiment of the present invention may further include a GPS for determining the position of the construction machine and transmitting the position data to the control device 40. [

Specifically, the control device 40 stores the headlight height recommended specification according to the position data of the construction machine. Headlight height recommendations include other recommended values for regional safety regulations.

A height adjusting device 30 for determining the position of the construction machine through GPS and adjusting the height of the headlamp 20 based on the recommended specifications for each area stored in the control device 40 according to the determined position data of the construction machine, Lt; / RTI >

With such a structure, the construction machine according to an embodiment of the present invention can determine whether or not the predetermined driving condition is met and adjust the vertical height of the headlamp 20 so that the visibility of the driver can be ensured have.

In addition, it is possible to prevent a safety accident that may occur due to the inability of the driver to secure the field of view.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.

It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
