Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, and particularly relates to a portable emergency stop device for a quay crane. Background Art

[0002] A quay container crane (referred to as a quay crane for short) is a professional device specifically used for loading and unloading container ships at a container terminal, and is generally installed at a port container terminal. During the manufacturing stage of the quay crane, commissioning operations of the mechanisms are required, and the commissioning operations include adjusting the installation positions of various mechanism components, commissioning the main functions and interlock functions of various mechanisms, etc. During the commissioning process of the quay crane, many personnel are working on the machine at the same time. At this time, the safety of the mechanism during vehicle movement is particularly important. Therefore, during the commissioning process, a vehicle movement monitoring team needs to be equipped for the quay crane during vehicle movement. One of the command personnel needs to patrol the route of vehicle movement or places where potential hazards may exist, and continuous patrols are also required during the vehicle movement process.

[0003] Some emergency stop buttons are equipped at various parts of the quay crane for emergencies, which can quickly and effectively stop the vehicle emergently. However, these buttons are all installed at fixed positions, cannot be moved, and cannot be carried. Since the vehicle movement command personnel need to patrol back and forth, they cannot use the emergency stop buttons at fixed positions in a timely manner. Therefore, on the one hand, once the vehicle movement command personnel discover a safety problem, the command personnel can only call the driver or electrical personnel through a walkie-talkie to operate the emergency stop button to stop the machine, and the entire process will take a lot of time. On the other hand, the vehicle movement command personnel themselves do not have protection measures. When the command personnel encounter danger, they do not have emergency handling measures and cannot ensure their own safety. Summary of the Utility Model

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the protection scope of the present utility model.

[0042] First, a portable quay crane emergency stop device according to an embodiment of the present utility model will be specifically described below with reference to the accompanying drawings.

[0043] Refer to Figure 1 , which shows the structural schematic diagram of the portable quay crane emergency stop device in some embodiments of the present utility model. As Figure 1 shown, the portable quay crane emergency stop device of the present utility model may include: a power supply 100, a wireless remote controller 200, and a wireless remote control 300. Among them, the input end of the wireless remote controller 200 is connected to the power supply 100, and the wireless remote controller 200 is respectively connected to the emergency stop circuit 101 and the reset circuit 102 of the quay crane; the wireless remote control 300 is wirelessly communicatively connected to the wireless remote controller 200. The wireless remote control 300 is used to control the wireless remote controller 200 to disconnect the emergency stop circuit 101 in an emergency, or to control the wireless remote controller 200 to close the emergency stop circuit 101 after the emergency is lifted. The wireless remote control 300 is further used to control the wireless remote controller 200 to close and then disconnect the reset circuit 102 after the emergency is lifted.

[0044] In this embodiment, by connecting the wireless remote controller 200 to the emergency stop circuit 101 and the reset circuit 102 of the quay crane, and at the same time enabling the commander to carry the wireless remote control 300 with him / her, during the commissioning process of the quay crane, when the commander discovers an emergency or is in danger himself / herself, he / she can promptly use the wireless remote control 300 carried with him / her to control the wireless remote controller 200 to disconnect the emergency stop circuit 101, thereby causing the quay crane to stop urgently. Thus, by enabling the commander to carry the wireless remote control 300 with him / her, the response speed in case of an emergency is improved, the personal safety of the staff can be protected, and the safety during the commissioning of the quay crane is effectively improved. After the emergency is lifted and it is ensured that the quay crane is in a safe state, the commander can use the wireless remote control 300 to control the wireless remote controller 200 to close the emergency stop circuit 101, thereby ensuring that an emergency will not be triggered again. Further, after the emergency is lifted, the commander can use the wireless remote control 300 to control the wireless remote controller 200 to close and then disconnect the reset circuit 102, so that the various devices of the quay crane can be quickly reset and the commissioning work can be carried out again. Thus, the commissioning efficiency of the quay crane is improved.

[0045] Reference Figures 1 - 3 , Figure 2 shows a schematic structural diagram of a portable emergency stop device for a quay crane in some embodiments of the present invention. Figure 3 is a schematic structural diagram of the reset circuit 102 of the quay crane in some embodiments of the present invention. As Figures 1 - 3 shown, the wireless remote controller 200 of the present invention may include: an emergency stop contact assembly 210 and a reset contact assembly 220. Among them, the emergency stop contact assembly 210 is connected in series to the emergency stop circuit 101, and the wireless remote control 300 is used to control the emergency stop contact assembly 210 to disconnect the emergency stop circuit 101 in case of an emergency. Thus, by connecting the emergency stop contact assembly 210 in series to the emergency stop circuit 101, the on-off state of the emergency stop contact assembly 210 can directly determine the conduction or disconnection of the entire emergency stop circuit 101, which is convenient for a quick response in case of an emergency, can effectively protect the personal safety of the staff in case of an emergency, and improves the safety during the commissioning of the quay crane. After the emergency is lifted, the commander can use the wireless remote control 300 to control the emergency stop contact assembly 210 to close the emergency stop circuit 101, thereby ensuring that an emergency will not be triggered again. The reset contact assembly 220 is connected in parallel to the reset circuit 102, and the wireless remote control 300 is used to control the reset contact assembly 220 to close and then disconnect the reset circuit 102 after the emergency is lifted. Thus, by connecting the reset contact assembly 220 in parallel to the reset circuit 102, the reset circuit 102 is temporarily conducted by closing the reset contact assembly 220 during reset, so that the various components of the quay crane can be quickly reset and the commissioning work can be carried out again. Thus, the commissioning efficiency of the quay crane is improved.

[0046] AsFigure 2 As shown in the figure, the emergency stop contact assembly 210 includes: an emergency stop normally closed contact 211 and a long-stroke travel switch 212. Among them, the emergency stop normally closed contact 211 is connected in series to the emergency stop circuit 101; the long-stroke travel switch 212 is connected in series to the emergency stop circuit 101. Under normal circumstances, the long-stroke travel switch 212 is in closed contact with the emergency stop normally closed contact 211. The wireless remote controller 300 is used to control the long-stroke travel switch 212 to disconnect from the emergency stop normally closed contact 211 in case of an emergency; the wireless remote controller 300 is also used to control the long-stroke travel switch 212 to make a closed contact with the emergency stop normally closed contact 211 again after the emergency is lifted.

[0047] In this embodiment, the long-stroke travel switch 212 can be in continuous closed contact with the emergency stop normally closed contact 211, that is, under normal circumstances, the long-stroke travel switch 212 is in closed contact with the emergency stop normally closed contact 211, so that the quay crane can normally perform commissioning operations. In case of an emergency, the wireless remote controller 300 is used to control the long-stroke travel switch 212 to disconnect from the emergency stop normally closed contact 211. Thus, the disconnection of the long-stroke travel switch 212 and the emergency stop normally closed contact 211 can disconnect the entire emergency stop circuit 101, effectively protecting the personal safety of the staff in case of an emergency and improving the safety during the commissioning of the quay crane. After the emergency is lifted, the commander can use the wireless remote controller 300 to control the long-stroke travel switch 212 to make a closed contact with the emergency stop normally closed contact 211 again, thereby ensuring that the emergency situation will not be triggered again.

[0048] As Figure 3 shown in the figure, the reset contact assembly 220 includes: a reset normally open contact 221 and a jogging travel switch 222. Among them, the reset normally open contact 221 is connected in parallel to the reset circuit 102; the jogging travel switch 222 is connected in parallel to the reset circuit 102. Under normal circumstances, the jogging travel switch 222 is disconnected from the reset normally open contact 221. The wireless remote controller 300 is used to control the jogging travel switch 222 to make an instantaneous closed contact with the reset normally open contact 221 and then disconnect after the emergency is lifted.

[0049] In this embodiment, the jogging travel switch 222 can make an instantaneous contact with the reset normally open contact 221, that is, after the emergency is lifted, the wireless remote controller 300 can control the jogging travel switch 222 to make an instantaneous closed contact with the reset normally open contact 221 and then disconnect, so that the reset circuit 102 is temporarily turned on, so that the various components of the quay crane can be quickly reset and the commissioning work can be carried out again. Thus, the commissioning efficiency of the quay crane is improved.

[0050] As Figure 1 shown in the figure, a circuit breaker 110 is connected between the input end of the wireless remote controller 200 and the power supply 100. By setting the circuit breaker 110, overload protection and short-circuit protection can be provided for the wireless remote controller 200 to prevent the wireless remote controller 200 from being damaged.

[0051] As Figure 1 shown, the portable quay crane emergency stop device further includes: an external antenna 400, which is electrically connected to the wireless remote control controller 200. The external antenna 400 is used to enhance the wireless signal of the wireless communication connection between the wireless remote control 300 and the wireless remote control controller 200. Thereby, the control distance and signal strength of the wireless remote control 300 can be effectively improved, and the response speed and the safety during the commissioning of the quay crane are effectively improved.

[0052] As Figure 1 shown, the wireless remote control 300 includes: an emergency stop button 310 and a reset button 320. Among them, the emergency stop button 310 is used to control the wireless remote control controller 200 to disconnect the emergency stop circuit 101 in case of an emergency, or to control the wireless remote control controller 200 to close the emergency stop circuit 101 after the emergency is lifted; the reset button 320 is used to control the wireless remote control controller 200 to close and then disconnect the reset circuit 102 after the emergency is lifted. By setting the emergency stop button 310 and the reset button 320, it is convenient for the command personnel to quickly execute the emergency stop command and the reset command, and the response speed and the commissioning efficiency of the quay crane are effectively improved.

[0053] As Figure 1 shown, the wireless remote control 300 is provided with an openable anti-misoperation cover 330, and the emergency stop button 310 and the reset button 320 are located below the anti-misoperation cover 330. Thereby, it is possible to prevent the command personnel from accidentally touching the emergency stop button 310 or the reset button 320, and the safety performance is improved.

[0054] In an embodiment of the present invention, the power supply 100 is the power supply of the quay crane control cabinet. Since the power supply of the quay crane control cabinet will not be frequently disconnected during the commissioning stage, the risk of the socket power supply being frequently disconnected manually during use is avoided, and the safety is effectively improved.

[0055] In an embodiment of the present invention, the portable quay crane emergency stop device further includes: an alarm (not shown), which is wirelessly communicatively connected to the wireless remote control 300. The wireless remote control 300 is used to control the alarm to give an alarm in case of an emergency.
