[0031] Furthermore, the early warning assembly 2 comprises a sleeve plate 20, the sleeve plate 20 is arranged at the top of the cross beam 1 and directly above the opening 15, a lifting rod 21 is sleeved with the inner wall of the sleeve plate 20, the lifting rod 21 has a certain friction with the inner wall of the sleeve plate 20 and can be inserted into the sleeve plate 20, the number of the lifting rods 21 is arranged as several groups, a side plate two 22 is arranged at one side of each of the several groups of lifting rods 21, a rotating shaft one 23 is rotatably connected with the inner wall of the side plate two 22, a baffle 24 is arranged at the outer surface of the rotating shaft one 23, a limiting plate 25 is arranged at the inner side of the side plate two 22, a connecting rod 26 is arranged at one side of the rotating shaft one 23, the baffle 24 is arranged at a 45-degree position of the rotating shaft one 23, the limiting plate 25 is arranged at a position close to the bottom of the side plate two 22, a LED sound and light alarm 30 is arranged at one side directly below the early warning assembly 2 and close to the early warning assembly 2, the light colors of each of the groups of LED sound and light alarms 30 are different, but the light colors of the LED sound and light alarms 30 of each of the warning positioning assemblies 3 are the same.

[0032] The triggering assembly 4 comprises a side plate three 40, the side plate three 40 is arranged at one side of the bottom of the LED sound and light alarm 30, a pressing plate 41 is rotatably connected with the inner side of the side plate three 40, a pin shaft three 44 is rotatably connected with one end of the bottom of the pressing plate 41, a rotating rod two 45 is arranged at one side of the pin shaft three 44, a pin shaft five 46 is arranged at one end of the rotating rod two 45, a sliding rail one 470 is arranged at the inner wall of the bottom of the LED sound and light alarm 30, a sliding plate 47 is slidably connected with the inner wall of the sliding rail one 470, one side of the sliding plate 47 is connected with the pin shaft five 46; a push rod 48 is arranged at the other side of the sliding plate 47, a spring 49 is sleeved with the outer surface of the push rod 48, one end of the spring 49 is connected with the outer surface of the pressing type electric switch 32, the pressing part of the push rod 48 and the pressing type electric switch 32 are on a straight line.

[0033] In real-time use, the plurality of tunnel collapse early warning devices are placed transversely in the tunnel where faults and insufficient support are prone to occur along the left and right walls of the tunnel, and then the lifting rod 21 in the early warning assembly 2 is placed on the top of the tunnel (the lifting rod 21 is set as a fixed adjustable telescopic rod, and the distance is calculated before installation, and the length of the lifting rod 21 is changed);

[0034] Further, the refuge mechanism 5 comprises a side plate four 50 installed at the bottom of one side of the cross beam 1, a rotating shaft two 51 rotatably connected to the inner side of the side plate four 50, a fixed plate 52 sleeved on the outer surface of the rotating shaft two 51, a sliding rail two 53 formed on one side of the fixed plate 52, a pin shaft four 54 slidably connected to the inner wall of the sliding rail two 53, a pull rod 55 rotatably sleeved on one end of the pin shaft four 54, and a rotating shaft three 550 rotatably sleeved on one end of the pull rod 55.

[0035] The warning positioning assembly 3 comprises LED sound and light alarms 30, which are set as multiple groups and are vertically installed on the outer surface of the fixed rod 31. Each group of the multiple groups of LED sound and light alarms 30 is provided with a press-type electric switch 32 at the bottom inner wall. In real-time use, the elastic force of the spring 49 acts on the push rod 48, the rotating rod one 43, the rotating rod two 45, the sliding plate 47 and the pressing plate 41, so that the pressing plate 41 is always kept horizontal and in a pressed state.

[0036] In real-time use, when deformation occurs at the top of the tunnel, the mountain will squeeze the group of lifting rods 21 downward, causing the lifting rods 21 to slide downward in the sleeve plate 20. At the same time, as the sliding track of the lifting rods 21 is aligned with the pressing plate 41 in the trigger assembly 4, the lifting rods 21 will push the pressing plate 41 to deflect to one side. At the same time, the pressing plate 41 will push the rotating rod one 43 and the rotating rod two 45 to rotate and extend through the pin shaft two 42, the pin shaft three 44, and the pin shaft five 46 by a certain angle, push the push rod 48, and press the spring 49 to press the push-type electric switch 32. The group of LED sound and light alarms 30 will emit light and alarm, reminding the staff in the tunnel. If the mountain continues to collapse, it will push the pressing plate 41 downward and continue to trigger the following groups of LED sound and light alarms 30 by pushing the pressing plate 41. The colors of each group of LED sound and light alarms 30 from top to bottom are blue, yellow, orange, and red, respectively. The brighter the color, the more serious the deformation of the tunnel at that location. When one group of lifting rods 21 is pressed by the deformation of the top of the tunnel, the lifting rods 21 on the left and right will be pulled by the connecting rod 26 installed on the rotating shaft one 23 inside the side plate two 22. Since the tunnel mountain generally expands downward in an arc shape, there will be a displacement difference between the surrounding lifting rods 21 and the middle lifting rods 21. The baffle 24 and the limiting plate 25 will limit the rotation of the rotating shaft one 23, that is, the middle group of lifting rods 21 will pull the surrounding lifting rods 21 only after a certain distance, preventing the lifting rods 21 from moving downward together. The purpose is to locate the group of lifting rods 21 with the maximum downward distance, making it easier to determine the accurate position of the tunnel mountain deformation by color. For example, if the middle group of lifting rods 21 corresponds to the red LED sound and light alarm 30, and the LED sound and light alarms 30 on both sides are orange, it means that the mountain has started to deform from the position corresponding to the red LED sound and light alarm 30, which also corresponds to the characteristics of the mountain deforming in an arc or triangular shape. Ultimately, it is convenient for staff to quickly locate the accurate position of the mountain deformation to avoid this location below and better escape.

[0037] Furthermore, the fixed plate 52 is vertically installed and closely attached to one side of the load-bearing column 12. The rotating shaft two 51 has a gear disc one 56 installed at both ends. The gear disc one 56 is meshed with a gear rack 57 on the outer surface. The gear rack 57 is meshed with a gear disc two 58 on the inner wall. The gear disc two 58 has a rotating shaft four 59 installed on the inner side. The rotating shaft four 59 has a side plate five 590 connected on one side. The side plate five 590 is installed at the bottom of the cross beam 1. The rotating shaft four 59 has a support plate 591 installed on one side. The support plate 591 is installed at an angle of 25 degrees. The fixed plate 52 has a limiting buckle 592 installed on one side near the bottom. The support plate 591 can slide up and down along the fixed plate 52 on one side through the pull rod 55, the rotating shaft three 550, and the pin shaft four 54 in the sliding track two 53.

[0038] In real-time use, when the tunnel collapses, due to the installation of the folding plate 14 in the middle of the beam 1, the folding plate 14 is not only thinner than the beam 1, but also more flexible than the beam 1, so when the mountain collapses the beam 1, the beam 1 will start to bend from the middle (such as Figure 8 and Figure 9 ), at the same time when the two groups of beams 1 bend, the part of the beam 1 installed with the load-bearing column 12 starts to rotate through the pin shaft 11, due to the change of the angle between the beam 1 and the fixed plate 52 when the beam 1 bends, the beam 1 drives the side plate five 590 at the bottom to rotate, and drives the side plate five 590 to rotate, due to the inner wall of the side plate five 590 movably sleeving the gear disc two 58 end of the rotating shaft four 59 is in linkage relationship with the gear rack 57 and the gear disc one 56, at this time when the side plate five 590 rotates, the positional relationship between the gear disc two 58 and the gear disc one 56 will change, so the gear disc one 56 will drive the gear disc two 58, the rotating shaft four 59 and the support plate 591 sleeved on the outer surface of the rotating shaft four 59 to rotate downward, drive the support plate 591 to move downward tightly against the fixed plate 52 under the limitation of the sliding rail two 53, the pin shaft four 54, the pull rod 55 and the rotating shaft three 550, until it abuts against the limiting buckle 592, (the limiting buckle 592 is integrally formed with the fixed plate 52 at the time of production) at this time the combination of the beam 1, the load-bearing column 12 and the support plate 591 forms a stable triangular structure, so that the load-bearing column 12 and the middle of the inclined beam 1 form a triangular cavity, the beam 1 supports the mountain, and can also block some falling rocks or soil, since the load-bearing column 12 and the beam 1 are both very hard steel material, so it is very difficult for the mountain to bend the load-bearing column 12 and the beam 1 by its own gravity, at this time the staff who can escape in time can hide in this cavity and wait for rescue by opening the first-aid kit 13 on the side of the load-bearing column 12, and pass the time when the rescue personnel reach the position of the trapped person by digging the mountain, improve the survival rate of the staff when the tunnel suddenly collapses and they can't escape in time (during work training, the staff should be warned to be close to the load-bearing column 12 in the tunnel when the early warning alarm occurs, and to escape from the side wall of the tunnel, so as to maximize the function of the refuge mechanism 5).
