[0037] Embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present utility model will now be described in detail, which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts. In addition, although the terms used in the present utility model are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present utility model may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the description herein. In addition, it is required to understand the present utility model not only by the actual terms used, but also by the meaning implied by each term.

[0038] As Figures 1 to 5 shown, the present utility model provides a safety monitoring and alarm device for the blind area of a container crane drum, which is characterized in that the safety monitoring and alarm device comprises:

[0039] A drum mechanism 100, which is arranged on one side of the crane machine room against the wall;

[0040] A brake 200, which is arranged on the side of the drum mechanism 100 and is used to brake the drum mechanism 100;

[0041] An infrared detection device 300, which is arranged between the drum mechanism 100 and the wall of the crane machine room;

[0042] An alarm 400, which is arranged in the crane machine room, and the alarm 400 is electrically connected to the infrared detection device 300;

[0043] A monitoring camera 500, which is arranged in the crane machine room and is aimed at the area between the drum mechanism 100 and the wall of the crane machine room.

[0044] The area between the drum mechanism 100 and the wall of the crane machine room is the blind area of the drum mechanism 100. The infrared detection device 300 is installed in the blind area of the drum mechanism 100 to realize blind area monitoring. At the same time, the monitoring camera 500 is also aimed at the blind area of the drum mechanism 100 to detect whether there are objects or personnel in the blind area. The alarm 400 is installed in the crane machine room where the drum mechanism 100 is arranged, and can realize on-site alarm.

[0045] The brake 200 usually brakes the drum mechanism 100. When the infrared detection device 300 detects that there are objects or personnel in the blind area of the drum mechanism 100, the brake 200 remains in the braking state and does not open, so that the drum mechanism 100 cannot operate, ensuring construction safety and preventing personnel from being injured.

[0046] Preferably, the brake 200 and the alarm 400 are linked with the infrared detection device 300. When the infrared detection device 300 detects an obstacle signal in the blind area, the brake 200 remains in the braking state and does not open, and the alarm 400 is immediately activated.

[0047] Preferably, the monitoring camera 500 is linked with the infrared detection device 300. When the infrared detection device 300 detects an obstacle signal in the blind area, the monitoring camera 500 is activated, and the staff determines whether there are objects or people in the blind area according to the monitoring screen of the monitoring camera 500.

[0048] As Figure 4 shown, preferably, infrared detection devices 300 are installed in the blind areas of the drum mechanisms 100 belonging to the three major mechanisms of hoisting, pitching, and trolley in the crane machine room, and an alarm 400 is installed beside the drum mechanism 100

[0049] As Figures 1 to 3 shown, as a preferred embodiment of the safety monitoring and alarm device for the blind area of the drum of the container crane of the present utility model, the safety monitoring and alarm device further includes a drum mechanism operating device, and the drum mechanism operating device is electrically connected to the drum mechanism 100; the drum mechanism operating device is used to operate the drum mechanism 100 to act and issue a drum mechanism action command signal; the alarm 400 is electrically connected to the drum mechanism operating device.

[0050] Whether the alarm 400 alarms is controlled by the drum mechanism action command signal and the signal sent by the infrared detection device.

[0051] As Figures 1 to 3 shown, as a preferred embodiment of the safety monitoring and alarm device for the blind area of the drum of the container crane of the present utility model, the safety monitoring and alarm device further includes a programmable logic controller 600 (PLC); the alarm 400 is electrically connected to the infrared detection device 300 and the drum mechanism operating device through the programmable logic controller 600 (PLC).

[0052] The programmable logic controller 600 includes output points and input points. The alarm is electrically connected to the output points of the programmable logic controller, and the infrared detection device and the drum mechanism operating device are electrically connected to the input points of the programmable logic controller.

[0053] The programmable logic controller 600 (PLC) is used for logical control of whether the brake 200 opens, whether the alarm 400 alarms, and whether the monitoring camera 500 is activated, and can detect the drum mechanism action command signal.

[0054] The programmable logic controller 600 (PLC) can realize the determination of whether the drum mechanism 100 can act and the on-site alarm determination.

[0055] When the programmable logic controller 600 (PLC) receives the signal sent when the infrared detection device 300 detects an obstacle, and when the programmable logic controller 600 (PLC) receives the action command signal of the reel mechanism, the programmable logic controller 600 (PLC) controls the alarm 400 to give an alarm, and the brake 200 maintains the braking state and does not open.

[0056] Figure 1 This is the alarm logic diagram of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model. The infrared detection device 300 detects the signal state of the blind area of the reel in real time and transmits it to the programmable logic controller 600 (PLC). When the detection state of the action command of the reel mechanism is true, and the infrared detection device 300 detects that an object or a person is blocked, the detection state is abnormal at this time. The programmable logic controller 600 (PLC) controls the alarm device of the reel of the mechanism to emit an alarm signal, the brake 200 maintains the braking state and does not open, and the reel mechanism 100 is not allowed to move until the monitoring state returns to normal, and then the reel mechanism 100 is allowed to move.

[0057] As Figures 1 to 3 shown, as a preferred embodiment of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model, the safety monitoring and alarm device further includes an intelligent remote controller 700, and the intelligent remote controller 700 is electrically connected to the infrared detection device 300 and the operating device of the reel mechanism.

[0058] As Figures 1 to 3 shown, as a preferred embodiment of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model, the intelligent remote controller 700 is communicatively connected to the cloud platform 800; the intelligent remote controller 700 collects the signal of the infrared detection device 300 and the action command signal of the reel mechanism 100 in real time and uploads them to the cloud platform 800 in real time.

[0059] The intelligent remote controller 700 can realize signal uploading to the cloud platform 800 and platform alarm. When the intelligent remote controller 700 receives the signal sent when the infrared detection device 300 detects an obstacle, and when the intelligent remote controller 700 receives the action command signal of the reel mechanism, the intelligent remote controller 700 uploads the signal to the cloud platform 800 and alarms the cloud platform 800. The intelligent remote controller 700 is preferably a 4G intelligent remote controller 700, and alarms the cloud platform 800 through the 4G network.

[0060] As Figures 1 to 3 shown, as a preferred embodiment of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model, the intelligent remote controller 700 is communicatively connected to the mobile terminal.

[0061] When the intelligent remote controller 700 receives the signal sent when the infrared detection device 300 detects an obstacle, and when the intelligent remote controller 700 receives the action command signal of the reel mechanism, the intelligent remote controller 700 alarms the mobile terminal.

[0062] Preferably, the 4G card is integrated in the intelligent remote controller 700, and the cloud platform 800 alarms and the alarm functions of mobile terminals such as mobile phones and tablets are realized through network connection to the cloud platform 800.

[0063] Preferably, the intelligent remote controller 700 transmits the monitoring screen to the mobile phone mobile terminal to realize mobile phone side monitoring.

[0064] Such as Figure 2 and Figure 3 As shown, the programmable logic controller 600 (PLC) and the intelligent remote controller 700 collect the action command detection status signal of the reel mechanism and the feedback signal of the infrared device in real time, and upload them to the cloud platform 800 in real time. When the two signals are collected simultaneously and meet the alarm conditions, the cloud platform 800 alarms and monitors on the mobile terminal.

[0065] As a preferred implementation manner of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model, the monitoring camera 500 is electrically connected to the programmable logic controller 600.

[0066] When the infrared detection device 300 detects an obstacle and sends a signal, and when the action command detection device of the reel mechanism detects the action command signal of the reel mechanism 100, the programmable logic controller 600 controls the monitoring camera 500 to start.

[0067] Preferably, the 4G card is integrated in the monitoring camera 500 to realize the monitoring and voice shouting functions of mobile terminals such as mobile phones and tablets, that is, through mobile terminals such as mobile phones and tablets, the monitoring screen can be viewed in real time when the monitoring camera 500 starts, and voice shouting can be performed through the monitoring camera 500.

[0068] Such as Figure 5 As shown, as a preferred implementation manner of the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model, a relay 510 is arranged between the monitoring camera 500 and the programmable logic controller 600, and the relay 510 controls the opening or closing of the monitoring camera 500.

[0069] Such as Figure 5The figure shows the schematic control structure of the monitoring camera 500. Only when the action command signal of the reel mechanism and the signal of the infrared monitoring device are detected simultaneously, the relay 510 represented by KM1 is energized and the monitoring camera 500 is started. The mobile terminal issues a reminder, and the monitoring camera screen is monitored to determine whether there is a person in the picture and whether to issue a voice reminder for the person to evacuate.

[0070] The blind area safety monitoring and alarm device for the reel of the container crane of the present utility model is used to monitor whether there are objects or people in the blind area of the machine room reel by the infrared detection device, and then transmit the signal to the programmable logic controller 600 (PLC) and the intelligent remote controller 700. The monitoring camera 500 starts the monitoring screen, and then judges whether the reel mechanism 100 can be started, whether the alarm 400 alarms, and whether to send an alarm reminder to the mobile terminal.

[0071] In summary, the blind area safety monitoring and alarm device for the reel of the container crane of the present utility model adds devices such as an infrared detection device and a monitoring camera in the blind area of the reel without affecting the original functions of the reel mechanism, enhances the blind area monitoring function, can remind production personnel to take self-evasive actions on site, and also improves the safety of vehicle movement during production debugging. It is of great help to the construction safety and construction efficiency during the production process of the crane; it has certain economic and social benefits for responding to the national call for safe production.
