Based on the dual mechanism for monitoring the travel of a large arc door provided in the first embodiment of the present application, the second embodiment of the present application proposes another dual mechanism for monitoring the travel of a large arc door. The second embodiment is only a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0043] Specifically, the difference of the dual mechanism for large arc door travel monitoring provided by the second embodiment of the present application is that a support rod 19 is installed on the top of the fixed bracket 2, and a mounting buckle 20 is fixedly connected to the top of the support rod 19, and the top of the mounting buckle 20 is rotatably connected to the protective frame 16 through a mounting head 21;
[0044] The protection frame 16 covers the outer surfaces of the angle sensor 11 and the arc door support arm rotating shaft 12 , and both sides and the bottom of the protection frame 16 are open.
[0045] One side of the protection frame 16 is rotatably connected to the telescopic assembly 18 via the second connecting buckle 22, and the other end of the telescopic assembly 18 is rotatably connected to the first connecting buckle 17;
[0046] The first connecting buckle 17 is connected to the top of the first cement column 1. The telescopic assembly 18 can provide assistance when the protective frame 16 is subjected to force for angle adjustment and can allow the protective frame 16 to be quickly reset when no force is applied.
[0047] The telescopic assembly 18 comprises a fixed tube 181, and the inner surface of the fixed tube 181 is fixedly connected to a limit strip 182 on the opposite side thereof, and one end of the inner wall of the fixed tube 181 is fixedly connected to a support spring 184 via a fixing sheet 183;
[0048] One end of the fixed tube 181 has a hole for allowing the movable rod 187 to move, and the other end of the fixed tube 181 is connected to the first connecting buckle 17 .
[0049] The other end of the support spring 184 is fixedly connected to a movable disk 186 via a support sheet 185, and the other end of the movable disk 186 is fixedly connected to a movable rod 187;
[0050] The outer surface of the movable plate 186 is provided with a groove into which the limiting strip 182 can be inserted, thereby increasing the stability of the movable plate 186 when it is moving. The other end of the movable rod 187 is connected to the second connecting buckle 22.
[0051] Compared with the related art, the dual mechanism for monitoring the travel of large arc doors provided by the utility model has the following beneficial effects:
