Abstract
The present invention provides an excavator that secures a field of view during excavation work and improves safety and work efficiency. The present invention relates to a vehicle comprising a traveling body, a main body rotatably mounted on the traveling body, a boom rotatably mounted on the main body, an arm having one end rotatably mounted on the boom, And a camera module mounted on one side of the arm for picking up the bucket.
Description
And more particularly, to an excavator that improves the visibility of a driver by picking up an image of an excavating operation at the time of work.
An excavator is a machine that collects digging or digging the earth or rock. Generally, an excavator has a lower traveling body, an upper rotating body, an engine, a boom, an arm, and a bucket. Under the engine driving, the lower traveling body is moved to change the working position, And operates to transfer the digging or digging of the soil or rock to the bucket by the mutual action of the boom and the arm.
During the work of the excavator, a safety fence is installed around the excavator for the safety of other workers or pedestrians, or a separate safety guard prevents people or objects from entering the work radius of the excavator.
However, the working environment of the excavator does not have a safety fence installed or a separate safety personnel available. Therefore, there is a need for a safe working environment for an excavator in a work environment where a safety fence or safety personnel can not be used.
In addition, the excavator is used to dig the surrounding ground or rock at the excavation site, but it is not easy for the operator to grasp the whole situation around the excavation site. Normally, the operator should check the surrounding situation while rotating the excavator or take a look at the excavation site by getting off the excavator. However, such circumstance confirmation work often occurs when the excavator is not easily operated depending on the work environment (for example, a space in which the upper rotator of the excavator is not smoothly rotated or a floor around the excavator is filled with water or mud). In this way, a means for easily grasping the surrounding environment is required in the current excavator.
In addition, excavators should be parked at a designated parking spot or at a parking area of an arbitrary parking lot after the end of the work. In such a case, when the other vehicle or equipment is parked in the vicinity of the vehicle due to the difference in vehicle width or vehicle length, It is not easy to park next to equipment or equipment. Thus, in the current excavator, appropriate means for easily grasping the surrounding environment is required for the convenience of the user.
In Korean Patent Laid-Open Publication No. 10-2014-0052436 (a side view device for an excavator), a camera is installed on the side of an excavator to secure a view from the side of the excavator.
Embodiments of the present invention aim to provide an excavator that secures a field of view during excavation work and improves safety and work efficiency.
According to an aspect of the present invention, there is provided a vehicle including a traveling body, a main body rotatably mounted on the traveling body, a boom rotatably mounted on the main body, an arm having one end rotatably mounted on the boom, A bucket rotatably connected to the arm, and a camera module mounted on one side of the arm for picking up an image of the bucket.
In addition, the camera module may include an imaging unit for imaging the bucket, and a housing provided at one side of the arm and housing the imaging unit.
The camera module may further include a driving unit for driving at least one of the imaging unit and the housing to adjust the position of the camera module. The camera module can capture the bucket in conjunction with the rotation of the bucket.
Further, the housing may be installed in the inside of the arm, one end thereof may be rotated with respect to the arm and protrude to the outside of the arm, and the image sensing unit may be installed at one end of the housing and pivotable about the housing .
In addition, the camera module can capture an end of the bucket.
The display device may further include a display unit for displaying an image captured by the camera module.
Further, the display unit may have an end portion of the picked up bucket positioned at the center of the display unit.
The apparatus may further include an angle sensor installed at the other end of the arm and measuring an angle between the arm and the bucket.
The controller may further include a controller for calculating a rotation angle of the camera module from information about a rotation angle of the bucket received from the angle sensor.
The camera module may further include an illumination unit that is spaced apart from the camera module and installed in the arm.
The excavator according to the embodiment of the present invention can easily grasp the image of the excavation work to improve the work efficiency and prevent the safety accident in advance.
In addition, the excavator can continuously photograph the end portion of the bucket by the camera module, and can keep the working view of the driver constant, so that the excavator can perform the excavation even in a position where the fine operation and the field of view are not secured.
In addition, the camera module of the excavator can effectively prevent the image pickup section from being contaminated by the foreign matter from the outside by arranging the image pickup section inside the housing.
