Description

Technical Field

[0001] The utility model relates to the technical field of overhead cranes, in particular to an anti-collision type overhead crane. Background Art

[0002] The multifunctional overhead crane is an important equipment in the electrolytic aluminum process. During its use, the multifunctional overhead crane may collide due to insufficient observation or operational errors. Currently, only mechanical collision buffering devices are installed on the overhead crane, which cannot prevent collisions. In addition, since the overhead crane works 24 hours a day and is used all year round, occasional failures may occur in the mechanical part, the electrical transmission part, or the PLC control part, requiring professional technicians to go up to the overhead crane for inspection, maintenance and repair. If the ground operator makes an uninformed mistake at this time, causing the overhead crane to move or the trolley on the overhead crane to start, it may cause harm to the maintenance personnel on the overhead crane. In addition, the overhead crane track is narrow, and maintenance personnel need to pass through the overhead crane track when repairing the overhead crane. If the ground personnel start the overhead crane without knowing it, it may cause serious harm to the maintenance personnel on the track. Utility Model Content

[0018] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0019] A collision-proof overhead crane, referring to Figure 1-2As shown, the system includes a first track 1, a longitudinal moving portion 2 positioned on the first track 1, two second tracks 3 positioned parallel to each other between the two longitudinal moving portions 2, a transverse moving carriage 4 positioned on the two second tracks 3, and an overhead crane main control system 9 fixedly connected to one of the longitudinal moving portions 2. The system also includes a first RGB-D camera 5, a second RGB-D camera 6, and a visual processing controller 7. The longitudinal moving portion 2 is provided with two first RGB-D cameras 5 radially facing the first track 1; the transverse moving carriage 4 is provided with two second RGB-D cameras 6 radially facing the second track 3; and the visual processing controller 7 is fixedly connected to the transverse moving carriage 4 and electrically connected to the first RGB-D camera 5, the second RGB-D camera 6, and the overhead crane main control system 9. The first RGB-D camera 5 and the second RGB-D camera 6 can be adjusted to form a visual monitoring area within a certain range.

[0020] It should be noted that the two longitudinal moving parts 2 located on the first track 1 provide drive for the entire overhead crane. The two second tracks 3 located between the two longitudinal moving parts 2 provide space for the transverse moving trolley 4. The overhead crane main control system 9 is the component that controls various motions and power supplies of the overhead crane. The first RGB-D camera 5 and the second RGB-D camera 6 can identify the distance between a person and the overhead crane and adjacent overhead cranes. The visual processing controller 7 analyzes 2D images and depth map data and transmits electrical signals to the overhead crane main control system 9. The first and second RGB-D cameras 5 and 6 can be commercially available products such as the DS86.

[0021] Specifically, the two first RGB-D cameras 5, located on the longitudinally movable portion 2 and fixedly attached radially to the first track 1, are positioned back-to-back. The two second RGB-D cameras 6, located on the transversely movable carriage 4 and fixedly attached radially to the second track 3, are also positioned back-to-back. This back-to-back arrangement of the first and second RGB-D cameras 5 and 6 facilitates the camera lenses to promptly capture the distance between a person and the overhead crane, as well as adjacent overhead cranes, enabling the crane to be stopped immediately.

[0022] Specifically, to facilitate ground personnel in receiving information about an emergency stop of the overhead crane, an audible and visual alarm 8 is fixedly attached to the side or bottom of the longitudinal movable portion 2. The audible and visual alarm 8 is electrically connected to the overhead crane main control system 9, which can transmit an electrical signal to the audible and visual alarm 8 to issue an alarm. The audible and visual alarm 8 is a commercially available product and will not be described in detail.

[0023] Specifically, in order to more conveniently control the overhead crane master control system 9, the overhead crane master control system 9 is remotely controlled via a wireless remote control transceiver 10. The wireless remote control transceiver 10 implements the functions of resetting the alarm light signal and disconnecting the safety protection system interlock.

[0024] Generally speaking, in order to facilitate adjustment of the viewing angles of the first RGB-D camera 5 and the second RGB-D camera 6, the first RGB-D camera 5 is detachably connected to the longitudinal movable portion 2; the second RGB-D camera 6 is detachably connected to the transverse movable carriage 4.

[0025] The working principle of this utility model:

[0026] Through the setting of the first RGB-D camera 5, when two adjacent overhead cranes approach the warning range detected by the first RGB-D camera 5, the first RGB-D camera 5 on the overhead crane transmits the 2D image and depth map data to the visual processing controller 7. After the visual processing controller 7 analyzes the 2D image and depth map data, it transmits the signal to the overhead crane main control system 9. The overhead crane main control system 9 sends an emergency stop signal to stop the overhead crane and sends a signal to the sound and light alarm 8 to alarm, effectively preventing the collision of adjacent overhead cranes; when the staff is in the process of maintenance, the overhead crane is running due to operational errors, and the Similarly, the first RGB-D camera 5 and the second RGB-D camera 6 can detect the distance between the operating overhead crane and a person. When a person enters the warning range, the first RGB-D camera 5 or the second RGB-D camera 6 transmits the 2D image and depth map data to the visual processing controller 7. After the visual processing controller 7 analyzes the 2D image and depth map data, it transmits the signal to the overhead crane main control system 9. The overhead crane main control system 9 sends an emergency stop signal to stop the overhead crane and sends a signal to the sound and light alarm 8 to alarm, effectively preventing the staff from colliding with the overhead crane during the maintenance process and causing personal injury.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
