Construction safety devices

Abstract

The present invention provides a construction safety device for use on construction machinery comprising a main body and a movable body that moves relative to the main body, which can prevent the restricted area from becoming unduly large. [Solution] A construction safety device 1 is installed and used in a construction machine 3 which is composed of a main body 5 and a movable body 7 that moves relative to the main body 5. The construction safety device 1 has a detection unit 11 that detects the position of the movable body 7 using a sensor 15, and an area setting unit 13 that sets a predetermined area as a no-entry area 17 based on the position of the movable body 7 detected by the detection unit 11.

Claims

1. A construction safety device used in construction machinery, comprising a main body and a movable body installed on the main body and moving relative to the main body, A detection unit that detects the position of the moving object using a sensor, A region setting unit sets a predetermined area as a no-entry zone based on the position of the moving object detected by the detection unit, A safety device for construction work that has the following features.

2. The detection unit is configured to detect the position of the object to be detected using the sensor. A determination unit determines whether or not an object detected by the detection unit exists within the restricted area set by the area setting unit, When the determination unit determines that the object detected by the detection unit is within the restricted area set by the area setting unit, the alarm generation unit issues a first alarm, A construction safety device according to claim 1, having the following:

3. The detection unit has a prediction unit that predicts whether or not there is a risk of the detected object crossing the first boundary, which is the outer edge of the restricted area, into the restricted area. When the prediction unit determines that the object to be detected may cross the first boundary and enter the restricted area, the alarm generating unit issues a second alarm. A construction safety device according to claim 1, having the following:

4. The safety device for construction work according to claim 2 or 3, wherein the detection unit is configured to detect the position of the moving body and the position of the object to be detected using at least two types of sensors selected from LiDAR, a camera, a millimeter-wave radar detector, and an ultrasonic radar.

5. The aforementioned construction machine is configured to include an operating unit and a machine control unit. The operating unit is configured to move under the control of the machine control unit in response to the operation of the operator of the construction machine, The alarm generation unit is configured to send a predetermined signal to the machine control unit when the determination unit determines that the object detected by the detection unit is within the restricted area set by the area setting unit. The construction safety device according to claim 4, wherein the machine control unit, upon receiving a predetermined signal from the alarm generating unit, is configured to stop the movement of the moving body or to slow down the movement speed of the moving body, even though an operation is being performed at the operation unit.

6. The construction safety device according to claim 1, wherein the area setting unit is configured to set a three-dimensional space of a predetermined size as a no-entry area, centered on at least one of the parts of the moving body that has the widest range of movement relative to the main body, or the part of the moving body that moves the fastest relative to the main body.

7. The aforementioned construction machine is a backhoe equipped with a traveling section and a rotating section. The aforementioned running unit is configured to include a running unit body and crawlers provided on both sides of the running unit body. The swivel section is installed above the main body of the travel section and supported by the main body of the travel section, and is configured to rotate about a central axis extending vertically relative to the main body of the travel section. The moving body is configured to move relative to the rotating part, The safety device for construction work according to claim 1 or claim 2, wherein the sensor is installed in the rotating section.

8. A detection unit (43) for detecting the rotation angle of the swivel section relative to the main body of the travel section, A display unit that displays the rotation angle of the turning part relative to the main body of the traveling part detected by the detection unit, A construction safety device according to claim 7, having the following:
