Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of monitoring systems, and in particular relates to an operation warning system for a port portal crane. Background Art
[0002] In recent years, with the rapid development of social economy, ports have played an increasingly important role in social and economic activities. Among them, port cranes play an important role in port operations. The manufacturers and users of port cranes are very concerned about the operational safety of port cranes. Cranes are mainly used to lift large and heavy cargoes, and relevant staff are needed to assist and cooperate with the crane operators to load and unload cargoes. In particular, gantry cranes require more auxiliary staff during operations because they lift a variety of cargoes.
[0003] However, the existing gantry cranes used in ports have high tower cranes and high operating platforms. Operators have to focus on the lifting of cargo, which makes it inconvenient for them to observe the ground operating area in real time. In addition, the lower part of the gantry cranes used in ports will also block the line of sight to a certain extent, hindering the operators from observing the ground operating area. Therefore, they cannot promptly detect the situation where other port staff members accidentally enter the operating area. Utility Model Content

The visual positioning module 30 is connected to the control module 10 and includes a first warning zone positioning module 310 and a second warning zone positioning module 320.
[0028] The first warning zone positioning module 310 is disposed at the bottom edge of the rotating platform 701 of the portal crane 70 and includes a first laser light 311, a second laser light 312, and a third laser light 313. The first warning zone positioning module 310 projects a first warning zone 50 on the ground around the portal crane 70.
[0029] The second warning zone positioning module 320 is disposed at the hook 702 of the gantry crane 70 and includes a fourth laser light 321. The second warning zone positioning module 320 projects a second warning zone 60 onto the ground below the hook 702 of the gantry crane 70. The second warning zone is located below the hook and serves as the hook's operating area, providing a warning. Furthermore, the operator's field of vision typically moves with the movement of the hook, allowing the operator to promptly observe the situation of personnel within the second warning zone.
[0030] The real-time monitoring module 20 is connected to the control module 10 and includes a first camera 201, a second camera 202, and a third camera 203. The first camera 201, the second camera 202, and the third camera 203 are arranged at the bottom edge of the rotating platform 701 of the portal crane 70. The positions of the first camera, the second camera, and the third camera correspond to the positions of the first laser light, the second laser light, and the third laser light, respectively, and monitor the first warning zone in real time. Since the first warning zone is located in the blind spot of the portal crane, the real-time monitoring module is provided for real-time monitoring.
[0031] The alarm module 40 is connected to the control module and is used to receive the warning instruction issued by the control module and issue a warning signal. It includes an audio warning device 401 and a warning light warning device 402. When it is detected that someone enters the first warning area, a warning audio signal and a light signal are issued.
[0032] This embodiment also includes a communication module 80 and a power module 90. The control module, real-time monitoring module, visual positioning module and alarm module are all connected to the communication module. The communication module is used for data transmission between the control module, real-time monitoring module, visual positioning module and alarm module. The control module, communication module, real-time monitoring module, visual positioning module and alarm module are all connected to the power module 90, and the power module is used to supply power to other modules.

For the convenience of description here, the side close to the water surface is the front, and the side away from the water surface is the rear. The third laser light and the third camera are installed on the right bottom edge of the rotating platform of the gantry crane. The positions of the first laser light and the third laser light are symmetrical about the line connecting the second laser light and the center of the rotating platform of the gantry crane.
[0034] In this embodiment, the first laser light, the second laser light and the third laser light are all red linear beam laser lights, which make the edge of the first warning zone a red U-shaped frame, which can usually demarcate a rectangular area about 22 meters long and 15 meters wide under the portal crane, and the beam width is about 10 cm. The fourth laser light is a yellow ring beam laser light, which makes the edge of the second warning zone a ring shape, specifically, it can be a circular ring frame with a diameter of about 15 meters, or it can be a square ring frame with a side length of 14 meters and a side thickness of about 10 cm. It mainly serves as a warning to facilitate personnel identification.
[0035] In this embodiment, the audio warning device is arranged on the tower of the gantry crane, and the warning light warning device is arranged at the lower part of the tower of the gantry crane. When someone breaks into the first warning area, the audio warning device is triggered and issues a similar warning prompt such as "You have entered the dangerous working area! Please leave immediately!"
[0036] The utility model forms a first warning zone by projecting a first warning zone positioning module on the ground around the portal crane. The first camera, the second camera and the third camera are used to monitor the first warning zone, mark the area and serve as a warning, and perform real-time monitoring through the first camera, the second camera and the third camera of the real-time monitoring module. Once it is detected that someone enters the first warning zone, a signal is immediately triggered to realize an alarm; the second warning zone positioning module forms a second warning zone by projecting a second warning zone on the ground in front of the hook of the portal crane, marks the operating area corresponding to the hook of the crane, serves as a warning and is convenient for the operator to observe.
[0037] The utility model provides an operation warning system for a port portal crane. The visual positioning module forms a first warning zone to serve as a warning. The real-time monitoring module monitors the first warning zone in real time, so that the operator and the personnel entering the first warning zone are warned, thereby ensuring the operation safety during the lifting operation.
[0038] The utility model aims at the blind spots and working areas of operators, forms the first warning zone and the second warning zone by projecting on the ground through the visual positioning module, and can monitor and alarm the first warning zone and the second warning zone in real time, which is conducive to timely discovering the situation where other port workers mistakenly enter the warning zone and maintain operational safety.
