DETAILED DESCRIPTION

[0025] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0026] In conjunction with Figures 1 to 6 The present application provides a safety belt protection auxiliary device, which comprises a safety belt body 1 and a connecting stitching block 11 located on the safety belt body 1. The rear side of the connecting stitching block 11 is connected with a safety rope 2, and the safety rope 2 is connected with two groups. The end of the safety rope 2 is connected with a hook 3.

[0027] The hook 3 comprises a hook body 31 and a lock rod 32 hinged with the hook body 31. The hinge of the hook body 31 and the lock rod 32 is provided with a torsional spring 33.

[0028] Further comprising a detection assembly 4 for detecting whether the hook 3 is installed.

[0029] The inside of the hook body 31 is provided with a sleeve 311. The detection assembly 4 comprises an abutting block 41 arranged on the inside of the hook body 31. The upper end of the abutting block 41 is provided with a sliding column 411 which is in sliding connection with the sleeve 311. The upper side of the sliding column 411 is provided with an elastic member 413. One end of the elastic member 413 is connected with the inner wall of the sleeve 311. The hook body 31 and the abutting block 41 are provided with a pressure sensor 42 and a signal transmitter 43. The pressure sensor 42 and the signal transmitter 43 are electrically connected.

[0030] The detection assembly 4 further comprises an installation box 44 arranged on one side of the connecting stitching block 11. The inside of the installation box 44 is provided with a controller 45, an alarm 46 and a power supply 47.

[0031] The power supply 47 is electrically connected to the controller 45 , the alarm 46 , the signal transmitter 43 and the pressure sensor 42 .

[0032] In this embodiment, after the operator puts on the safety belt body 1, he hangs the hook 3 at the end of the safety rope 2 at a specified position. When the hook 3 is hung on the specified object, the object contacts the contact block 41, and under the action of the tension, the contact block 41 is squeezed by the object, so that the contact block 41 drives the sliding column 411 to slide inside the sleeve 311, so that the elastic member 413 is squeezed. At the same time, the contact block 41 squeezes the pressure sensor 42 when moving, and the pressure sensor 42 transmits the signal to the controller 45 through the signal transmitter 43. The controller 45 receives the pressure sensor signal. 42, the status of the pressure sensor 42 is monitored in real time. If the pressure sensor 42 detects that the pressure exceeds the set threshold, it means that the hook 3 has been correctly hung. If the hook 3 is not hung, the resistance block 41 is in the initial state under the elastic force of the elastic member 413. Then, at this time, the pressure sensor 42 does not detect the pressure, and the controller 45 determines that the hook 3 is not in the hanging position. When the controller 45 confirms that the pressure sensor 42 does not detect the expected pressure, the controller 45 will trigger the alarm 46 to work, and the alarm will send a sound signal to prompt the operator to check the status of the hook 3.

[0033] Combine Figure 4 and Figure 5 As shown, a limiting plate 412 is provided on the top of the sliding post 411 , a limiting groove 312 is provided inside the sleeve 311 , and the limiting plate 412 is slidably connected to the inside of the limiting groove 312 .

[0034] In this embodiment, when the resistance block 41 drives the sliding column 411 to move inside the sleeve 311, the sliding column 411 drives the limiting plate 412 to move along the limiting groove 312. When the limiting plate 412 moves to the end of the limiting groove 312, the position of the resistance block 41 is fixed. The setting of the limiting groove 312 and the limiting plate 412 can prevent the resistance block 41 from moving excessively, which will cause the pressure sensor 42 to be squeezed and damaged.

[0035] Combine Figure 6 As shown, mounting ears 442 are provided on both sides of the mounting box 44, and the mounting ears 442 are connected to the connecting suture block 11 by bolts;

[0036] A through slot 441 is defined on the outside of the installation box 44 , and the alarm 46 corresponds to the through slot 441 .

[0037] In this embodiment, the installation box 44 is installed by bolts, so that when the internal components of the installation box 44 are damaged, they can be easily replaced. By opening the through slot 441, the sound of the alarm 46 can be better transmitted.
