[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3 A ship loader windproof iron shoe return detection device includes an inspection frame 1 and a placement rack 11 installed inside the rear end of the inspection frame 1. The iron shoe component 7 is installed inside the placement rack 11. A lower bracket 12 is installed inside the rear end of the inspection frame 1 and above one side of the placement rack 11. A return limit switch 14 is installed inside the lower bracket 12. An upper bracket 13 is inserted at the top of the return limit switch 14 and above the lower bracket 12. Inspection doors 4 are provided on both sides of the front end of the inspection frame 1. Hinges 5 are installed on both sides of the inspection frame 1. One side of the hinge 5 is installed on the outer surface of the inspection door 4. A pin 6 is installed between the two sets of inspection doors 4. The inspection frame 1 and the return limit switch 14 protect the iron shoe and the return limit, preventing accidental activation. The iron shoe component 7 can be limited and maintained through the inspection doors 4.

[0023] Handles 3 are installed on both sides of the top of the inspection frame 1. A sound and light alarm 2 and a protective component 8 are installed on the outside of the inspection frame 1. A threaded hole A15 is opened on the outer surface of the inspection frame 1. The top two sides of the inspection frame 1 are inclined to prevent foreign objects from falling onto the iron shoe piece 7 and from accidentally triggering the return limit switch 14. The inclined inspection frame 1 can prevent foreign objects from accumulating on its top. The inspection frame 1, handles 3, inspection door 4 and placement rack 11 are made of 305 stainless steel. Their size is made according to the size of the iron shoe piece 7 on site and the actual environment.

[0024] The rear end of the inspection frame 1 is equipped with a mounting box 16, and a PLC 17 is installed inside the mounting box 16. The PLC 17 is electrically connected to the audible and visual alarm 2 and the return limit switch 14. The return limit switch 14 is connected to the same circuit. If any one of them is removed from the placement frame 11, a signal will be sent to trigger an alarm and interlock the action.

[0025] In this embodiment: the two sets of return limit switches 14 are model WLNJ-2 / OMRON, and the audible and visual alarm 2 is model HY-BG1. Under normal operating conditions, the iron shoe 7 is on the placement rack 11, and the lever of the return limit switch 14 is pressed by the iron shoe 7. The audible and visual alarm 2 does not respond, and the ship loader operator's screen does not alarm. Under strong wind conditions, the iron shoe 7 is removed from the placement rack 11. After the lever of the return limit switch 14 returns to its original state, it sends a signal. The PLC 17 controls the audible and visual alarm 2 to provide on-site alarm reminders. At the same time, it controls the ship loader operator's screen to provide operational alarm reminders. In addition, this signal is also interlocked with the corresponding mechanism of the ship loader, and the corresponding mechanism is prohibited from operating. All return limit switches 14 are connected to the same circuit. If any iron shoe 7 is removed from the placement rack 11, a signal will be sent to alarm and interlock the operation.

[0026] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The protective component 8 includes a base plate 83 and side plates 81 installed on both sides of the base plate 83. An L-shaped cover plate 85 is installed at the upper end between the two sets of side plates 81. A connecting plate 89 is installed on one side of the top of the L-shaped cover plate 85. A threaded hole B891 is opened through the middle of the connecting plate 89. A bolt 9 is threaded inside the threaded hole B891. The threaded hole B891 is aligned with the threaded hole A15. The threaded end of the bolt 9 is threaded into the inside of the threaded hole A15 to fix the position of the protective component 8. The protective component 8 is used to protect the audible and visual alarm 2.

[0027] A motor 87 is installed on the inner side of the L-shaped cover plate 85. A rotating shaft 871 is installed at the output end of the motor 87. A cover plate 86 is installed at one end of the L-shaped cover plate 85, the side plate 81, and the bottom plate 83. An opening 861 is opened at the upper end of one side of the cover plate 86. One end of the rotating shaft 871 is installed inside the opening 861. The PLC 17 is electrically connected to the motor 87. When the iron shoe piece 7 is removed from the inside of the placement rack 11, the PLC 17 controls the motor 87 to operate, moving the cover plate 86 away from one end of the side plate 81 to facilitate the sound transmission of the audible and visual alarm 2. After the iron shoe piece 7 is completely returned to the inside of the placement rack 11, the rotating shaft 871 rotates back. The cover plate 86 is used to protect the audible and visual alarm 2, which has rotated back to one end of the side plate 81. The protective component 8 protects the audible and visual alarm 2, preventing the audible and visual alarm 2 from being shortened due to the harsh environment of the port.

[0028] A sealing ring 88 is installed inside the cube formed by the base plate 83, the L-shaped cover plate 85 and the two sets of side plates 81. A transparent plate 82 is installed at the middle of the side plate 81. The transparent plate 82 makes it easy for the operator to observe the color change of the sound and light alarm 2. The sealing ring 88 is used to seal the inside of the protective component 8.

[0029] A magnetic strip A84 is embedded in the outer surface of the side plate 81 and the side near the cover plate 86. A magnetic strip B862 is embedded in the outer surface of the cover plate 86 and the side near the side plate 81. The magnetic strip B862 and the magnetic strip A84 are attracted by opposite poles, which fixes the position of the cover plate 86 and prevents the sealing state of the protective component 8 from being affected by the strong wind in the port.

[0030] In this embodiment: when placing the iron shoe piece 7, the PLC17 controls the motor 87 to operate, and drives the cover plate 86 to rotate through the rotating shaft 871. When the iron shoe piece 7 is missing, the alarm sound emitted by the audible and visual alarm 2 can be transmitted through the base plate 83. The transparent plate 82 makes it easy for the operator to observe the reminder color emitted by the audible and visual alarm 2. After placement, the rotating shaft 871 rotates in the opposite direction, and the cover plate 86 returns to its original position. The magnetic strips B862 and A84 are magnetically attracted to each other, fixing the position of the cover plate 86. The sealing ring 88 seals the environment inside the protective component 8, preventing the harsh environment of the port from affecting the service life of the audible and visual alarm 2.

[0031] Working principle: When the iron shoe part 7 is detached from the placement rack 11, the rod of the return limit switch 14 returns to its original state and sends a signal, which controls the sound and light alarm 2 through PLC17 to provide on-site alarm reminder, and at the same time controls the operation screen of the ship loader operator to provide operation alarm reminder.
