[0036] Working principle: When it is necessary to install the protection plate 32, first put the fixed frame 22 on the outer surface of the fixed column 21, then apply a turning force to the guide column 292 to take out the threaded rod 291 from the fixed plate 27 and the inside of the movable column 26. Apply a pushing force to the movable column 26 to insert the limit column 24 into the fixed column 21 and the fixed frame 22. Then apply a turning force to the guide column 292 to turn the threaded rod 291 into the corresponding connection hole 28 and the inside of the fixed plate 27;

[0037] This step quickly and efficiently disassembles and installs the protection frame from the bottom of the device, facilitating the inspection and repair of the flash lamp.

[0038] Please refer to Figures 1-4 As shown, a normally closed stall alarm device for a trackless rubber-tyred vehicle further includes a reinforcement component. The reinforcement component includes a mounting post 31, a protection plate 32, a threaded hole 321, a mounting frame 33, and a magnet block 34. The mounting post 31 is slidably connected to the inside of the connecting post 23. The protection plate 32 is fixed to the outer surface of the mounting post 31. The mounting frame 33 is fixed to the outer surface of one side of the protection plate 32. The magnet block 34 is fixed to the inside of the mounting frame 33. The threaded hole 321 is opened in the inside of the mounting post 31 and the connecting post 23.

[0039] The mounting post 31 is used to fix the protection plate 32 at the required position. The protection plate 32 is used to protect the flash lamp at the bottom of the device. The inside of the threaded hole 321 is used to receive and install screws, thereby fixing the mounting post 31 inside the connecting post 23. The mounting frame 33 is used to receive and install the magnet block 34. The magnet block 34 is used to connect with the iron column 36.

[0040] The outer surface of the magnet block 34 is magnetically connected to an iron column 36. The outer surface of the iron column 36 is slidably connected to a connecting frame 35. The outer surface of the connecting frame 35 is fixed to the outer surface of the other side protection plate 32. A moving groove 37 is opened inside the connecting frame 35. A connecting rod 38 is fixed to the outer surface of the iron column 36. The connecting rod 38 is located inside the moving groove 37.

[0041] By fixing the iron column 36 inside the mounting frame 33, the two protection plates 32 can be connected together. The connecting frame 35 is used for the iron column 36 to move inside it. The moving groove 37 is used for the connecting rod 38 to move inside it. The connecting rod 38 facilitates applying a pushing force to the iron column 36.

[0044] Working principle: When the protection board 32 is damaged and needs to be replaced, apply an upward pulling force to the guide rod 393 to compress the spring 392. After the limit rod 39 disengages from the inside of the connecting rod 38, apply a pushing force to the connecting rod 38. The connecting rod 38 slides inside the moving groove 37, and the iron column 36 retracts into the connecting frame 35. Remove the screw inside the threaded hole 321, apply a downward pulling force to the protection board 32, and the old protection board 32 can be disassembled. Then cut and paste the installation frame 33 or the connecting frame 35 on the outer surface of the new protection board 32. Insert the installation column 31 into the connecting column 23, and then fix the screw inside the threaded hole 321. Apply an upward force to the guide rod 393 and a pushing force to the connecting rod 38 to connect the iron column 36 with the magnet block 34;

[0045] This step adopts a split design, which can replace the protection board 32 specifically and reduce the maintenance cost.
